Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of U.S. Provisional Patent Application No. 63/593,928 filed on Oct. 27, 2023, and titled “COLLAPSIBLE SHELTER WITH FLEXIBLE RODS,” the disclosure of which is expressly incorporated by reference in its entirety.

BACKGROUND

Field

Certain aspects of the present disclosure generally relate to folding, collapsible structures.

Background

Portable rooms, such as tents, screened rooms, or other temporary enclosures, have become essential in various scenarios where a flexible and mobile shelter is needed. These portable structures offer the convenience of transportation and assembly at diverse locations for a wide range of purposes. For example, a tent may serve as a temporary shelter for camping or outdoor recreation, providing protection from the elements while offering a space for rest and relaxation. Similarly, a screened room may be used to offer protection from insects and other pests while allowing occupants to enjoy an unobstructed view of the surrounding environment. In more specialized applications, such as emergency response, portable rooms may be erected quickly for use in crime scene investigations, as medical treatment stations, or even as clean areas to control contamination in sensitive operations.

Despite their versatility, conventional portable rooms often face challenges related to structural stability, particularly when exposed to adverse weather conditions. For instance, tents and other lightweight structures are susceptible to wind pressure, which can lead to deformation, collapse, or displacement. In addition, water pooling on the roof or other surfaces during heavy rain can place undue strain on the structure, increasing the risk of damage and compromising the comfort and safety of the inhabitants. These issues not only affect the durability and usability of portable rooms but also pose significant safety concerns for users, particularly in environments where adverse conditions are unpredictable.

Conventional portable shelters, such as portable canopies, designed primarily for ease of transport and basic protection, often face significant challenges when it comes to maintaining structural stability in varying environmental conditions. Many portable canopies are constructed using a simple frame with a fabric cover, supported by a few poles. While this minimalist design is sufficient for calm weather and temporary use, it frequently underperforms in more demanding conditions, such as heavy rain or strong winds.

One of the most common issues with portable shelters is the pooling of water on the shelter's surface (e.g., roof), particularly in flat-topped designs or those without proper tensioning systems. As water accumulates on the shelter roof, it adds considerable weight, which can strain the structure and fabric. Over time, this additional weight can stretch and weaken the material, increasing the risk of tearing. Furthermore, water pooling increases the likelihood of leaks, as even minor imperfections in the seams or fabric can allow water to seep through. As these small leaks expand over time, they can lead to interior dampness, which compromises both the comfort of the occupants and the integrity of any equipment or materials stored under the canopy.

Wind also presents several challenges for portable shelters. Inadequately anchored or tensioned canopies are prone to flapping in the wind, which not only causes noise and discomfort but also leads to wear and tear, especially at seams and connection points. In stronger winds, the poles that support the shelter may bend or even break, particularly when wind strikes the shelter's broad side. This risk is exacerbated when the poles are made from rigid materials that lack the flexibility to absorb wind pressure. Additionally, in windy environments like beaches or deserts, portable canopies can be infiltrated by sand or dust, making the interior uncomfortable for occupants and potentially harmful for sensitive equipment.

The aforementioned challenges directly impact the safety and comfort of shelter users. A shelter susceptible to water pooling risks interior flooding, which can damage equipment, furniture, or supplies stored underneath. In windy conditions, a canopy that deforms or collapses poses a significant safety risk, potentially injuring occupants or leaving them exposed to the elements. While design innovations, such as geodesic or tunnel-shaped shelters, have been developed to improve wind resistance and stability, there remains significant room for further innovation to address the wide range of environmental challenges that portable shelters face.

Various aspects of the present disclosure are directed to a collapsible shelter that integrates detachable flexible rods within the roof structure. These flexible rods create a support system that significantly enhances the structural stability of the canopy, particularly in adverse weather conditions. In some examples, the shelter also includes reinforced trusses, a reinforced central hub, mounting hooks, and a positive lift truss system. Together, these elements optimize water runoff, reduce the risk of pooling, and maintain structural integrity in windy conditions. The flexible rods, which may be permanent or removable, provide strength both laterally and vertically, improving the stability of the shelter and offering additional support for mounting accessories at the central hub. This design offers a versatile and robust solution for outdoor settings, addressing many of the challenges faced by conventional portable shelters.

FIG. 1A illustrates an example of a conventional shelter 100 with sidewalls 101 and side skirts 106 attached to the legs 104. The sidewalls 101 and side skirts 106 may be formed of a fabric material such as a polyester fabric. As previously discussed, in conventional systems, the sidewalls 101 and side skirts 106 may attach directly to the legs 104 or perimeter truss via a connection, such as a fastener attached to a strap. The connections are neither secure nor taut. Therefore, the sidewalls 101 and side skirts 106 are prone to sagging or disconnecting from the legs 104. Additionally, or alternatively, banners, flags, and/or other types of dressings may be mounted to the legs and/or frame. As an example, half walls 110 may also be mounted to the legs 104. FIG. 1B illustrates another example of a booth structure 150 with flags 180 and banners 190 may be mounted to the legs 154.

As shown in FIGS. 1A and 1B, the sidewalls 101, side skirts 106, flags 180, and banners 190 are visible from the exterior of the shelter 100. The sidewalls 101, side skirts 106, flags 180, and banners 190 may have information printed on both sides. Still, there is unused space on the interior of a shelter's dome (e.g., ceiling). Still, the space on the interior of the shelter's dome may also be used to provide information (e.g., advertisements). Conventional fastening systems do not provide a system for attaching structures, such as flags and banners to an interior of the shelter.

It is desirable to provide a system to improve a customer's ability to attach various structures to a shelter. Aspects of the present disclosure are directed to a multi-point attachment system that provides multiple points in a shelter for securely fastening a structure, such as a flag, banner, side skirt, tent, etc., to the shelter's frame. According to aspects of the present disclosure, the multi-point attachment system provides a solution for a customer to attach different structures to the interior and/or exterior of the frame.

In one configuration, the multi-point attachment system provides attachment points at a center of a shelter as well as corners of the shelter. Of course, aspects of the present disclosure are not limited to providing attachment points at the center and all corners, as various configurations are contemplated based on a customer's need.

Some shelters may have a roof structure that is elevated with a telescoping peak beam. The peak beam may be connected to a bracket (e.g., center bracket) with multiple sockets. The sockets may receive one end of the peak beam as well as ends of truss links. In one configuration, one or more attachment points are provided at the center bracket.

FIG. 2 illustrates an example of a center bracket 200, in accordance with various aspects of the present disclosure. As shown in FIG. 2, an end of a peak beam 220 is coupled to a center socket 202 of the center bracket 200. The end of the peak beam 220 may be secured to the center socket 202 via a bolt 222 or other type of fastener. The center socket 202 may be a square shaped socket for receiving an end of the peak beam 220. Of course, the center socket 202 may have other shapes, such as a circle or other parallelogram, based on a shape of the peak beam 220.

Additionally, the center bracket 200 includes multiple side sockets 206 extending from the body of the center bracket 200. In one configuration, each socket is at substantially right angles from an adjacent socket 206. FIG. 2 illustrates the center bracket 200 with four sockets 206. In some examples, a shelter may use the center bracket 200 with four sockets 206 as more or fewer sockets 206 are contemplated. Aspects of the present disclosure are not limited to shelters with the center bracket 200. In some examples, a different type of center bracket may be used. Alternatively, in some examples, a shelter does not use a center bracket, such as the center bracket 200 described in FIG. 2.

Each socket 206 is coupled to a truss link 204 via a bolt 222 or other type of fastener. The truss links 204 may pivot within the respective sockets 206. In one configuration, to allow a truss link 204 to pivot when coupled to a socket 206, the sockets 206 include three sides (e.g., two arms 216 and a base 218). Furthermore, as shown in FIG. 2, a handle 208 is attached to each socket 206. In one configuration, the handle 208 is u-shaped and is attached to an outer side of the base 218. The inner side of the base 218 refers to a side that is adjacent to a truss link 204. Aspects of the present disclosure are not limited to the handles 208 having a u-shape and are contemplated for other designs that allow for a fastener 210, or other apparatus, to attach to the handle. Aspects of the present disclosure are not limited to the handles 208 being attached to the outer side of the base 218 and are contemplated for the handles 208 being attached to other portions of the center bracket 200.

As shown in FIG. 2, the fastener 210 is attached to the handle 208. As an example, the fastener 210 may be a hook, clasp, clip, or other type of structure to be coupled with the handle 208 of the socket 206. An opening 214 of the fastener 210 may receive a connector from a dressing, such as a wall, sidewall, skirt, flag, and/or banner. That is, the opening 214 is specified to receive a strap or material connected to a dressing, such as a wall, sidewall, skirt, flag, and/or banner.

FIG. 3 illustrates an example of a fastener 300, in accordance with various aspects of the present disclosure. In some examples, the fastener 300 is provided for attaching a dressing or structure to an attachment point, such as a handle of a bracket. As shown in FIG. 3, the fastener 300 includes a hook portion 302 that curves at a top of the fastener 300. A portion of the fastener 300 extends outward at the nose of the hook portion 302 to form a v-shaped end 304 for the fastener 300. As previously discussed, the fastener 300 is adapted to clip to a handle of a bracket. The v-shaped end 304 improves the retainment of the fastener 300 with a handle (e.g., attachment) of a multi-point attachment system.

Furthermore, as shown in FIG. 3, in one configuration, a strap 306 is extended through the opening 308 of the fastener 300. The opening 308 may be defined in a rectangular shaped end 310 of the fastener 300. Of course, aspects of the present disclosure are not limited to the fastener 300 having a rectangular shaped end 310 as other shapes are contemplated. The strap 306 may be sewn (e.g., connected) to a material of a dressing, such as a sidewall or skirt. Aspects of the present disclosure are also contemplated for the strap 306 to be connected to material of other structures, such as a tent, a flag, an inner wall extending along the roof of the canopy, or any other type of dressing (e.g., structure/fabric/material). In one configuration, the length of the strap 306 is adjustable.

In some examples, attachment points are defined on leg brackets of a shelter. The attachment points on the leg brackets may be provided alternate to or in addition to the attachment points of the center bracket. FIGS. 4A and 4B illustrate examples of different views of a leg bracket 400 in accordance with various aspects of the present disclosure. FIG. 4A illustrates a first view (e.g., front view) of the leg bracket 400 and FIG. 4B illustrates a second view (e.g., back view) of the leg bracket 400. The second view is opposite of the first view. As shown in FIGS. 4A and 4B, the leg bracket 400 is connected to a leg 402 of the collapsible frame. That is, a socket 420 of the leg bracket 400 receives an end of the leg 402. The leg 402 may be attached to the socket 420 via a bolt or other attachment (not shown).

The leg bracket 400 includes multiple sockets 404 extending outward from a body 412 of the leg bracket 400. Each socket 404 may be at substantially right angle from an adjacent socket 404. Aspects of the present disclosure are not limited to two sockets 404 as shown in FIGS. 4A and 4B; the leg bracket 400 may have one or more sockets 404. For example, in one configuration, the leg bracket 400 includes only one socket 404 extending outward from a body 412 of the leg bracket 400.

An end of a link member 408 is received in each socket 404 of the leg bracket 400. The end of the link member 408 may be pivotally connected to the socket 404. Specifically, the end of the link member 408 may be attached to the socket via a bolt 424 or other attachment. The socket 404 of the leg bracket 400 includes two arms 416. As a roof and a floor are not defined for each socket 404 of the leg bracket 400, the link member 408 may pivot in an up or down direction.

In one configuration, a handle 410 (e.g., attachment point) is defined below each socket 404. A first end of the handle 410 may be attached to a bottom of one arm 416 of the socket 404 and a second end of the handle 410 may be attached to the body 412 of the leg bracket 400. Each handle 410 may be adaptable to receive a fastener 414. As previously discussed, the fastener 414 is adapted to be connected to material of a structure via a strap or other type of connector. The leg bracket 400 is not limited to receiving link members and may receive telescoping pole members, flexible rods, or other structures of a frame of a shelter. Additionally, or alternatively, each leg bracket 400 may include additional sockets. For example, each bracket may include three sockets, wherein a third socket pivotally receives an inner truss link.

FIG. 5 illustrates an example of a frame of a shelter 500. The shelter 500 may be a modular folding shelter, such as a display booth. As shown in FIG. 5, the frame has four sides 504 and four corners. Each side 504 may be substantially perpendicular to one or more adjacent sides 504. Of course, aspects of the present disclosure are not limited to a frame with four sides and four corners, as other configurations, such as three sides and three corners, are also contemplated. Additionally, adjacent sides 504 may be connected at an angle that is greater than or less than 90 degrees. The frame may be collapsible. In another configuration, the frame is fixed.

In one configuration, legs 508 are provided at each corner to erect the frame. The legs 508 may be telescoping (e.g., extendable). That is, each leg 508 may comprise a telescoping lower section 520 that extends from a hollow upper section 522. The telescoping lower section 520 may be slidably disposed within the hollow upper section 522. Each telescoping lower section 520 has a foot 540 for engagement with the ground. Additionally, a perimeter truss frame 550 is connected to the legs 508 via brackets 524, 526 to stabilize and support the frame of the shelter 500. The perimeter truss frame 550 may also be referred to as a perimeter truss framework.

The perimeter truss frame 550 may include multiple outer truss links 552 and multiple inner truss links 554. Two outer truss links 552 may form an outer truss link pair. The outer truss links 552 of each outer truss link pair may be pivotally connected to each other at a cross-link joint 536, such as in a scissor configuration. In one configuration, a first end of each outer truss link 552 is pivotally connected to a leg 508 via either a leg bracket 524 or a sliding bracket 526. That is, a first end of one outer truss link 552 of each outer truss link pair may be pivotally connected to a socket of the leg bracket 524. Each socket of the leg bracket 524 may include an attachment point (e.g., handle) for receiving a fastener (see FIGS. 4A-B). The first end of another outer truss link 552 of each outer truss link pair may be pivotally connected to a socket of a sliding bracket 526, such that one outer truss link 552 of an outer truss link pair is slidably connected to a corresponding leg 508. A second end of each outer truss link 552 may be connected to a second end of another outer truss link 552 at an outer joint 530. The outer joint 530 may be a three-way joint.

As shown in FIG. 5, two inner truss links 554 may be pivotally connected at a cross-link joint 536 to form an inner truss link pair. Two inner truss links 554 may be pivotally connected, such as in the scissor configuration. In one configuration, a first end of a first inner truss link 554 is pivotally connected to a second end of two outer truss links 552 at an outer joint 530. A second end of the first inner truss link 554 of each inner truss link pair is pivotally connected to a peak slider 518. Furthermore, a first end of a second inner truss link 554 of each inner truss link pair is pivotally connected to a second end of two outer truss links 552 at an outer joint 530. A second end of the second inner truss link 554 of each inner truss link pair is pivotally connected to a socket of the center bracket 528. Each socket of the center bracket 528 may include an attachment point (e.g., handle) for receiving a fastener (see FIG. 2).

The shelter 500 may include a peak beam 532 for supporting a roof structure (not shown), such as a canopy. The peak beam 532 may be attached to a center bracket 528. The peak slider 518 may also be slidably attached to the peak beam 532. In one configuration, a peak pole 534 is telescoping (e.g., extendable) from the peak beam 532. That is, the peak beam 532 may be hollow so that the peak pole 534 may extend upward from the peak beam 532. The peak pole 534 may be slidably disposed within the peak beam 532. Additionally, the peak pole 534 may include a top bracket 538 for engaging a roof structure, such as a canopy.

The top bracket 538 may also include attachment points. In one configuration, a sail banner may be attached to an attachment point of the top bracket 538 and an attachment point on one or more leg brackets 524. Additionally, or alternatively, the sail banner may be attached to other components of the shelter. The sail banner may be used to display information on the interior of the shelter 500. In one configuration, a roof material may be placed on the shelter 500. In this configuration, the roof structure is placed over the sail banner, such that only the roof structure is visible from the exterior of the shelter 500, while both the roof structure and the sail banner are visible from the interior of the shelter 500.

FIG. 5 illustrates an example of a sliding bracket 526 according to aspects of the present disclosure. As shown in FIG. 5, a leg 508 passes through an opening of the sliding bracket 526. A pin 502 is used to engage the sliding bracket 526 with an opening in the leg 508 to keep the sliding bracket 526 in a desired position. The sliding bracket 526 includes one or more sockets 542 for engaging an end of a truss link, such as an outer truss link 552. A truss link may pivot within the socket 542. In one configuration, the sliding bracket 526 includes one or more attachment points of the multi-point attachment system.

Aspects of the present disclosure are not limited to the frame of the shelter 500, other frame types are contemplated. The frame of the shelter 500 shown in the example of FIG. 5 does not include flexible rods. Therefore, this frame may struggle with maintaining structural stability in diverse environments. It may be desirable to add flexible rods to the frame of the shelter 500.

FIG. 6 illustrates an example of a frame for a shelter 600 with a peak shape roof in accordance with aspects of the present disclosure. The shelter 600 may be a modular folding shelter, such as a display booth. As shown in FIG. 6, the shelter 600 has four sides 604 and four corners. Each side 604 may be substantially perpendicular to one or more adjacent sides 604. Of course, aspects of the present disclosure are not limited to a shelter 600 with four sides and four corners, as other configurations are also contemplated. The shelter 600 may be collapsible. The shelter 600 shown in the example of FIG. 6 does not include flexible rods. Therefore, this shelter 600 may struggle with maintaining structural stability in diverse environments. It may be desirable to add flexible rods to the shelter 600.

In one configuration, legs 608 are provided at each corner to erect the shelter 600. The legs 608 may be telescoping (e.g., extendable). That is, each leg 608 may comprise a telescoping lower section 624 that extends from a hollow upper section 622.

The telescoping lower section 624 may be slidably disposed within the hollow upper section 622. A slider 628, such as a slider with a pull pin, may be used to extend the telescoping lower section 624 from the hollow upper section 622. Each telescoping lower section 624 has a foot 640 for engagement with the ground. Additionally, a perimeter truss frame 616 is connected to the legs 608 for stability and support.

The perimeter truss frame 616 may include multiple outer truss links 612. Two pivotally connected outer truss links 612 may form an outer truss link pair. The outer truss links 612 of each outer truss link pair may be pivotally connected to each other at a cross-link joint 636, such as in a scissor configuration. In one configuration, a first end of each outer truss link 612 is pivotally connected to a leg 608 via a sliding bracket 664 or a leg bracket 668. Specifically, the first end of one outer truss link 612 of each outer truss link pair may be pivotally connected to a socket of a sliding bracket 664. The first end of another outer truss link 612 of each outer truss link pair may be pivotally connected to a socket of the leg bracket 668, such that each outer truss link 612 is pivotally connected to a corresponding leg 608. The leg bracket 668 and/or the sliding bracket 664 may include one or more attachment points (see FIGS. 4A-B). A second end of each outer truss link 612 may be connected to a second end of another outer truss link 612 at an outer joint 630.

As shown in FIG. 6, the frame may include multiple upper peak truss links 614 and lower peak truss links 632. A first end of each upper peak truss link 614 may be pivotally connected to a leg bracket 668. A second end of each upper peak truss link 614 may be pivotally connected to a peak center bracket 606. The peak center bracket 606 may include one or more attachment points of the multi-point attachment system. Each upper peak truss link 614 may also include a peak joint 638, such that a first portion 614a and a second portion 614b of each upper peak truss link 614 are foldable. A first end of a lower peak truss link 632 may be pivotally connected to the upper peak truss link 614 at a truss joint 634. A second end of the lower peak truss link 632 may be pivotally connected to socket of a sliding bracket 664. Each socket of a sliding bracket 664 may include a handle for receiving a fastener.

The lower peak truss links 632 may provide support to a corresponding (e.g., adjacent) upper peak truss link 614. The upper peak truss links 614 form a peak for supporting a roof structure (not shown), such as a canopy. The lower peak truss links 632 and/or upper peak truss links 614 may be made of a rigid material or flexible material. The truss links may form a dome shape roof, a pyramid shape roof, or other type of roof.

FIG. 7 illustrates an example of a shelter in a partially collapsed position. As shown in FIG. 7, a perimeter truss link assembly 700 having multiple perimeter truss pairs of link members 706 is connected to each leg 702. Each of the perimeter truss pairs including first link members 708 and second link members 710 that are pivotally connected together, such as in a scissor configuration. The first link member 708 and second link members 710 have inner ends 712 and outer ends 714. The outer end 714 of each first link member 708 connected to the upper end of one leg 702 via a leg bracket 720, and the outer end 714 of each second link member 710 being connected to a sliding leg bracket member 716 so as to be slidably connected to the leg 702. The inner ends 712 may be pivotally connected to each other. Each leg 702 may comprise a hollow upper section 726 and a telescoping lower section 728, with the lower section slidably disposed within the upper section, with the lower section having a foot section 770 for engagement with the ground. An end 722 of each leg 702 is connected to the leg bracket 720.

Various aspects of the present disclosure describe a collapsible shelter designed for portability and enhanced structural stability, particularly in outdoor environments. The shelter features a set of supporting legs, which are interconnected by outer truss links positioned between each pair of legs. These outer truss links improve the shelter's overall stability, ensuring the shelter remains secure and upright even in challenging weather conditions. In some examples, the shelter includes the flexible rod mounting system, which may be removably attached to the outer truss links. This mounting point acts as an anchor for one end of a flexible rod, while the other end of the flexible rod connects to a central hub located at the top of the structure. The central hub also connects to a group of inner truss links, which adds another layer of support and strength to the shelter. In addition, the shelter may include integrated mounting hooks that connect to the support rods, allowing the structure to bear additional weight, enhancing both functionality and durability.

The shelter's design further incorporates one or more truss muscles, which reinforce the roof structure. These truss muscles are connected to the inner truss links and are designed to add upward pressure, increasing the rigidity of the ceiling. This upward force is applied through a truss support hook, which helps the roof maintain its tension and shape, particularly under stress from wind or other forces. In some configurations, each truss muscle is removably connected to at least one inner truss link, allowing for flexibility in its positioning. The truss muscle acts as a bridge between primary and secondary inner truss links, both of which are pivotally connected. This arrangement enables the truss muscle to apply a positive lift force to the second inner truss link, helping the entire structure retain its shape and ensuring that the roof does not sag or collapse under strain.

The central hub may include two sets of sockets. The first set of sockets may receive the flexible rods, while the second set connects pivotally with the inner truss links. The respective sockets are oriented differently, with the first set angled in relation to the second set, such that the flexible rods and truss links create a balanced, tensioned structure that can withstand various environmental stresses.

Once the structure is fully assembled, a protective cover may be placed over the framework, enveloping the flexible rods, inner truss links, and outer truss links. This cover serves a dual purpose: it shields the occupants and the interior from the elements, such as rain or sunlight, while also contributing to the overall aesthetic appeal of the shelter.

In some examples, the process for setting up the collapsible shelter begins by unfolding the shelter and extending the supporting legs, which are stabilized by the outer truss links. These truss links provide the foundational stability required to keep the shelter upright. The next step is to locate the removable flexible rod mounting points on the outer truss links, which serve as anchors for the flexible rods. After attaching one end of the flexible rod to the mounting point, the rod is extended toward the central hub, maintaining a balanced tension that adds structural integrity to the shelter. The other end of the flexible rod is inserted into a socket on the central hub, which connects to the inner truss links. These inner truss links are pivotally attached to the central hub, and their orientation, facilitated by the distinct angles of the sockets, ensures an even distribution of tension throughout the structure.

To further enhance the stability, a truss muscle is attached to the inner truss links. This truss muscle provides additional upward pressure, strengthening the roof and preventing any sagging or instability. Once the framework is complete, a protective cover is draped over the structure. This combination of flexible rods, truss links, and truss muscles ensures a shelter that is not only easy to set up but also robust, durable, and capable of withstanding a variety of outdoor conditions. The design optimizes both performance and durability, making it suitable for a wide range of applications, from recreational use to more demanding environments.

FIG. 8 is a diagram illustrating an example of a collapsible shelter 800, in accordance with various aspects of the present disclosure. The collapsible shelter 800 may be a modular folding shelter, such as a display booth. As shown in FIG. 8, the collapsible shelter 800 has four sides and four corners. Other shelters are contemplated, such as a shelter with three sides and three corners. Each side may be substantially perpendicular to one or more adjacent sides.

In one configuration, legs 808 are provided at each corner to erect the collapsible shelter 800. The legs 808 may be telescoping (e.g., extendable). That is, each leg 808 may comprise a telescoping lower section 824 that extends from a hollow upper section 822. The telescoping lower section 824 may be slidably disposed within the hollow upper section 822. A slider (not shown in the example of FIG. 8), such as a slider with a pull pin, may be used to extend the telescoping lower section 824 from the hollow upper section 822. Each telescoping lower section 824 may include a foot 840 for engagement with the ground.

The legs 808 may be interconnected by outer truss links 812 to provide a stable foundation. These outer truss links 812 prevent the legs from spreading apart or collapsing inward, ensuring the collapsible shelter 800 maintains its shape. The outer truss links 812 may form a perimeter truss. Two pivotally connected outer truss links 812 may form an outer truss link pair. The outer truss links 812 of each outer truss link pair may be pivotally connected to each other at a cross-link joint, such as in a scissor configuration. In one configuration, a first end of each outer truss link 812 is pivotally connected to a leg 808 via a sliding bracket 864 or a leg bracket 868. Specifically, the first end of one outer truss link 812 of each outer truss link pair may be pivotally connected to a socket of a sliding bracket 864. The first end of another outer truss link 812 of each outer truss link pair may be pivotally connected to a socket of the leg bracket 868, such that each outer truss link 812 is pivotally connected to a corresponding leg 808. The leg bracket 868 and/or the sliding bracket 864 may include one or more attachment points (see FIGS. 4A-B). A second end of each outer truss link 812 may be connected to a second end of another outer truss link 812 at an outer link connector 830.

As shown in FIG. 8, the frame may include multiple upper peak truss links 814 and lower peak truss links 632. For ease of explanation, the upper peak truss links 814 may be referred to as upper truss links 814. Two upper truss links 814 may be pivotally connected to each other. A first end of a first upper peak link 814, in a pair, may be pivotally connected to a socket of a leg bracket 866. The leg bracket 866 is an example of a fixed leg bracket. A second end of the first upper peak truss link 814, in the pair, may be pivotally connected to a first end of a second upper peak link 814, in the pair. A second end of the second upper peak link 814, in the pair, may be pivotally connected to a peak center bracket 806. The peak center bracket 806 may include two different sets of attachment points. The peak center bracket 806 may also be referred to as center bracket, a central bracket, a center hub, or a central hub (hereinafter used interchangeably). Each upper peak truss link 814 may also include a peak joint, such that a first portion and a second portion of each upper truss link 814 are foldable. A truss muscle may be coupled to each pair of upper truss links 814. A first end of a lower peak truss link 832 may be pivotally connected to the upper peak truss link 814 at a truss joint. A second end of the lower peak truss link 832 may be pivotally connected to the socket of a sliding bracket 864. One or more sockets of a sliding bracket 864 and/or the leg bracket 866 may include a handle for receiving a fastener. The lower peak truss link 832 may also be referred to as a lower truss link 832.

The lower peak truss links 832 may provide support to a corresponding (e.g., adjacent) upper peak truss link 814. The upper peak truss links 814 form a peak for supporting a roof structure (not shown), such as a canopy. The lower peak truss links 832 and/or upper peak truss links 814 may be made of a rigid material or flexible material. The truss links may form a dome shape roof, a pyramid shape roof, or other type of roof.

As shown in FIG. 8, the collapsible shelter 800 also includes flexible rods 850. One end of each flexible rod 850 may be attached to the central hub 806. Another end of each flexible rod 850 may be attached to a respective mounting device 852 removably attached to an outer truss link 812. Each flexible rod 850 may be detachable from the central hub 806 and the corresponding mounting device 852. The curved and flexible design of each flexible rod 850 may improve an ability of the collapsible shelter 800 to withstand environmental forces such as wind and rain. The combination of flexible rods 850 and truss links 812 and 814, along with the central hub 806, provides a balanced and durable structure. The flexible rods 850 help manage external pressures, while the truss links 812 and 814 reinforce the frame, ensuring that the collapsible shelter 800 remains sturdy in various outdoor conditions. The flexible rods 850 may be constructed from aluminum, which is known for its lightweight properties, excellent strength-to-weight ratio, and corrosion resistance. Aluminum is particularly advantageous in outdoor environments, where exposure to the elements requires materials that can withstand moisture, temperature changes, and other environmental stressors without compromising structural integrity.

In addition to aluminum, the flexible rods 850 may be manufactured from other materials to suit different performance needs. For example, carbon fiber offers high tensile strength and stiffness while being extremely lightweight. Carbon fiber rods may provide resistance to bending or deformation. Another option is fiberglass, which, like carbon fiber, provides strength and flexibility. Steel is another potential material for the flexible rods, particularly when added strength and durability are needed. Additionally, polymer-based composites such as reinforced plastic can be used to manufacture the flexible rods. These materials combine flexibility with durability and are often reinforced with fibers such as glass or carbon to increase their strength. Polymer composites can be engineered for specific weather resistance, including resistance to moisture, UV exposure, and temperature fluctuations.

By allowing the flexible rods 850 to be made from a variety of materials, the design of the collapsible shelter 800 can be improved for specific environmental conditions, performance requirements, and cost considerations. This versatility in material selection ensures that the shelter remains sturdy, lightweight, and adaptable to a wide range of outdoor conditions.

FIG. 10A is a diagram illustrating an example of a mounting device 852 attached to a truss link 812A, in accordance with various aspects of the present disclosure. As shown in the example of FIG. 10A pairs of truss links 812A, 812B and 812C, 812D may be pivotally coupled to each other in a scissor configuration via respective cross link joints 1000. One end of each truss link 812A, 812B, 812C, and 812D in one truss link pair may be pivotally attached to an end of another truss link 812A, 812B, 812C, and 812D from an adjacent truss link pair. For example, an end of a first truss link 812A may be pivotally attached to an end of a third truss link 812C at an outer link connector 830. Additionally, an end of a second truss link 812B may be pivotally attached to an end of a fourth truss link 812D at outer link connector 830. The first truss link 812A and the second truss link 812B are a truss link pair, and the third truss link 812C and the fourth truss link 812D are a truss link pair. As shown in FIG. 10A, the mounting device 852 may be detachably coupled with one of the truss links, such as the first truss link 812A. The mounting device 852 may be mounted to one truss link 812, such that the mounting device 852 faces an inner portion of a shelter and is adjacent to a highest outer link connector 830 of two outer link connectors 830 that pivotally attach neighboring truss link pairs. As discussed, in some examples, an outer link connector 830 may be used to secure the mounting device 852 to an outer truss link 812. A flexible rod 850 may be inserted into a mounting point (e.g., receiving hole) of the mounting device. The flexible rod 850 may be detachable from the mounting point.

FIG. 10B is a diagram illustrating an example of a mounting device 852 attached to a truss link 812A, in accordance with various aspects of the present disclosure. As shown in the example of FIG. 10B, the first truss link 812A and a third truss link 812C may be pivotally attached together via an outer link connector. In some examples, the outer link connector may be an example connector that allows the first truss link 812A to be pivotally attached to the third truss link 812C. For example, the outer link connector may be a bolt or another type of connector for connecting the two outer truss links 812A and 812C. In some examples, the outer link connector may pass through a through hole 1010 off the mounting device to pivotally connect the two outer truss links 812A and 812C, as well as attaching the mounting device 852 to the first truss link 812. Each outer truss links 812A and 812C may include a respective through hole for receiving the outer joint connection. In other examples, a separate connector (e.g., bolt) may be used to attached the mounting device 852 to the first truss link 812. In such example, the separate connector is distinct from the outer link connector.

The mounting device 852 may be mounted to one truss link 812, such that the mounting device 852 faces an inner portion of a shelter. The mounting device 852 may clip onto the first truss link 812A. As noted, the mounting device 852 may be detachable from a truss link 812, such as the first truss link 812A.

The mounting device 852 may be constructed from a polymer, such as nylon 6, which offers mechanical strength, durability, and resistance to abrasion. Nylon 6 may be desirable due to its flexibility and ability to withstand environmental stresses such as wind and varying temperatures, while maintaining its integrity. The material's combination of strength and flexibility allows it to perform similarly to a well-tuned spring-able to flex under pressure but strong enough to return to its original form.

Still, aspects of the present disclosure are not limited to nylon 6, as various other materials may be used in the construction of the mounting device 852, depending on specific mechanical and environmental requirements. These materials include, for example, polypropylene, polycarbonate, or acrylonitrile butadiene styrene (ABS).

In some embodiments, the mounting device 852 may be made from lightweight metal alloys, such as aluminum or titanium, which offer superior strength and corrosion resistance while keeping the overall weight low for ease of assembly and transport. Alternatively, reinforced composites, such as fiberglass or carbon fiber, can be utilized for increased load-bearing capacity and enhanced resistance to wear and deformation, similar to the strength of a bridge reinforced with steel cables.

The flexibility to use a wide range of materials allows the truss muscle to be tailored to the specific needs of different environments and applications. This versatility ensures that the mounting device 852 can meet a variety of performance criteria, from strength and flexibility to weather resistance and cost efficiency.

FIGS. 11A and 11B are diagrams illustrating an example of a mounting device 852, in accordance with various aspects of the present disclosure. As discussed, the mounting device 852 is used to secure one end of a flexible rod that contributes to the overall stability and functionality of the structure.

FIG. 11A shows a perspective view of the mounting device 852. As shown in the example of FIG. 11A, mounting device 852 includes a cylindrical mounting point 1102 positioned at the top, which serves as a receiving structure for one end of a flexible rod or another component.

The groove 1104 may be used to clip onto a truss link, such as a truss link 812 described with respect to FIGS. 8, 9A, 10A, and 10B. The mounting device 852 facilitates the quick assembly and disassembly of the structure but also provides enhanced strength and durability to the overall framework. The mounting point 1102 allows for effective tension distribution and load management, which improves the shelter's integrity in outdoor environments. A through hole 1010 may be defined on the back of the body 1100. As discussed, the through hole 1010 may receive a connector, such as an outer link connector, to connect the mounting device to one or more outer truss links. The through hole 1010 extends from the back of the body 1100 to the front face of the body 1100, as depicted in FIGS. 11A and 11B. This through hole may accommodate a connector, such as a bolt, which passes through the through hole 1010 and one or more corresponding through holes located in the respective outer truss links. The connector, in this case, can be an example of a bolt (or another type of connector) where the diameter of the bolt's head is larger than the diameter of the through hole 1010, ensuring that the bolt can be secured to the mounting device 852.

Furthermore, the connector may have a head on both ends, allowing it to be securely fastened to both the mounting device 852 and one of the outer truss links 812. This dual-headed design ensures a tight, stable connection, preventing the bolt from slipping out and maintaining the overall structural integrity of the shelter. The secure fastening between the mounting device and the outer truss link through the connector provides essential support, allowing the shelter's framework to remain rigid and resilient against external forces, such as wind or movement.

FIG. 12 is a diagram illustrating an example of a mounting assembly of a mounting device 852, in accordance with various aspects of the present disclosure. As shown in the example of FIG. 12, a flexible rod 850 is attached to a mounting point 1102 of the mounting device 852. As discussed, the mounting point 1102 is used to hold the flexible rod 850 securely in place, ensuring that the flexible rod 850 remains firmly attached during use and can withstand external forces such as wind or rain. The flexible rod 850 extends from the mounting point at an angle, contributing to the overall tension and flexibility of the shelter's structure, allowing the flexible rod 850 to absorb stress without compromising stability. The body 1100 provides a strong base for the attachment of the flexible rod. The mounting device 852 is attached to a truss link or other framework component of the shelter via the groove 1104.

FIG. 13A is a diagram illustrating an example of a central hub 806 connected to an upper truss link 814, in accordance with various aspects of the present disclosure. The central hub 806 may be pivotally attached to multiple truss links and may also receive ends of multiple flexible rods. The central hub 806 maintains the integrity of the collapsible shelter's roof structure. As shown in FIG. 13A, the upper truss link 814 is pivotally connected to the central hub 806 via a socket 1302 of the central hub 806. The central hub 806 also includes mounting points 1300 for receiving respective ends of flexible rods. The mounting points 1300 may be positioned at downward angles to receive the flexible rods, which may be positioned at upward angles. By accommodating both the upper truss links 814 and the flexible rods, the central hub 806 ensures that forces exerted on the shelter are evenly distributed, providing enhanced stability in varying weather conditions.

The central hub 806 may also include one or more handles 208, such as a handle 208 described with reference to FIG. 2. In some examples, the central hub 806 only includes one handle 208. The handle 208 may be defined in a center of the central hub 806. In other examples, the central hub 806 may include multiple handles 208. As shown in the example of FIG. 13A, the upper truss link 814 is positioned at an angle relative to the central hub, illustrating the structural configuration that forms part of the shelter's roof. The pivotal nature of the connection allows the truss links to fold and unfold as needed during the shelter's assembly and disassembly, contributing to the overall modular and collapsible design.

FIG. 13B is a diagram illustrating an example of a central hub 806 connected to a flexible rod 850, in accordance with various aspects of the present disclosure. As shown in FIG. 13B, the central hub 806 serves as the anchor point for the flexible rod 850, which is a component in supporting the shelter's roof. The flexible rod 850 is attached to the central hub 806 at one of the mounting points, helping to create the desired tension and curvature necessary for the shelter's stability and structural integrity. The central hub 806 may include multiple mounting points for receiving the ends of flexible rods. The connection point for the flexible rod 850, as illustrated, provides stability while allowing the rod to be positioned at an upward angle to support the roof structure. The flexible rod 850 is shown in an arched position, which helps to distribute tension across the shelter's roof and ensures that the shelter can withstand external forces such as wind or rain. The central hub 806, as in FIG. 13B, also features a handle 208, which can be used to receive a detachable hook connected to a component, such as an internal sail, as needed.

FIG. 13C is a diagram illustrating an example of the central hub 806 connected to the flexible rod 850, in accordance with various aspects of the present disclosure. The central hub 806 serves as a component that anchors both flexible rods and truss links, ensuring the structural stability of the collapsible shelter's roof. As shown in the example of FIG. 13C, one end of the flexible rod 850 is connected to the central hub 806 through a mounting point 1300. The mounting point 1300 is designed to securely hold the flexible rod 850, allowing it to extend outward at an upward angle. This angled positioning of the flexible rod 850 helps create tension across the shelter's roof, contributing to the overall support and shape of the shelter. Additionally, the central hub 806 includes a truss link socket 1302, which serves as a pivotal connection point for a truss link (not shown in FIG. 13C). This socket allows for the attachment of a truss link, facilitating the modular and collapsible nature of the shelter by enabling easy folding and unfolding during assembly and disassembly. The central hub 806 also features a handle 208, located at its center.

FIG. 14A is a diagram illustrating an example of a top-side view of the central hub 806, in accordance with various aspects of the present disclosure. For ease of explanation, the central hub 806 may also be referred to as the hub 806. As shown in the example of FIG. 14A, the hub 806 includes multiple sockets 1302 around its perimeter, which are designed to receive the ends of the truss links, allowing for a secure and pivotal connection that contributes to the modular nature of the shelter.

The hub 806 includes multiple mounting points 1300 around its perimeter (only one is shown in FIG. 14A), each mounting point 1300 may receive the end of a flexible rod or another structural element. The flexible rod is detachable from the mounting point 1300. The positioning of the mounting point 1300 also helps to maintain the shape of the roof by distributing forces evenly across the framework. Additionally, a handle 208 is located at the center of the hub 806. The multiple truss link sockets 1302 positioned along the outer edge of the hub 806 are symmetrically arranged, enabling the even distribution of load and tension across the shelter's structure. These sockets allow the truss links to pivot, facilitating the collapsible nature of the shelter, making it easier to fold and unfold during transport or storage.

The pivotal nature of the connection between the truss links and the sockets 1302 contributes to the shelter's collapsibility and portability.

In addition to the truss link sockets 1302, the underside of the hub 806 includes mounting points 1300. Each mounting point 1300 receives an end of flexible rods, which may be positioned at upward angles to create tension and support for the roof of the shelter. The placement and orientation of the mounting points 1300 ensure that the flexible rods are securely anchored while allowing for the even distribution of forces across the shelter's roof structure. The hub 806 also includes a handle 208.

FIG. 15A is a diagram illustrating an example of a truss muscle 950 between two upper truss links 814A and 814B, in accordance with various aspects of the present disclosure. In the example of FIG. 15A, the two upper truss links 814A and 814B form an upper truss link pair. The truss muscle 950 adds additional structural support and rigidity to the shelter's roof by increasing the tension between adjacent truss links. As such, the truss muscle 950 helps maintain the overall shape and stability of the shelter, particularly under environmental forces such as wind or rain.

As shown in FIG. 15A, the upper truss links 814A and 814B are pivotally connected and reinforced by the truss muscle 950. The truss muscle 950 spans between the two upper truss links 814A and 814B and exerts an upward pressure, or positive lift, on a second upper truss link 814B via a truss support hook 1500. This positive lift ensures that the shelter's roof remains taut and resistant to sagging under external loads.

As shown in FIG. 15A, the truss support hook 1500 engages the second upper truss link 814B. The truss muscle 950 is attached to an end of the first upper truss link 814A. The truss support hook 1500 stabilizes the upper truss links 814A and 814B by providing an additional anchoring point for the second upper truss link 814B. Thus, the truss muscle 950 increases the rigidity of the upper truss links 814A and 814B, preventing unwanted movement or deformation in the truss links. This further contributes to the overall stability of the shelter, especially in challenging weather conditions.

As shown in the example of FIG. 15A, the first upper truss link 814A and a second upper truss link 814B may be pivotally attached together via an upper link connector 1502 (e.g., upper truss link connector). In some examples, the upper link connector 1502 may be an example connector that allows the first upper truss link 814A to be pivotally attached to the second upper truss link 814B. For example, the upper link connector 1502 may be a bolt or another type of connector for connecting the two upper truss links 814A and 814B. In some examples, the upper link connector 1502 may pass through a through hole (not shown in FIG. 15A) of the truss muscle 950 to pivotally connect the two upper truss links 814A and 814B. Each upper truss link 814A and 814B may include a respective through hole for receiving the upper link connector 1502.

The upper link connector 1502 may be an example of a bolt (or another type of connector) where the diameter of the bolt's head is larger than the diameter of a through hole defined on each upper truss link 814A and 814B, ensuring that the upper link connector 1502 can be secured in place. Furthermore, the upper link connector 1502 may have a head on both ends, allowing it to be securely fastened to both the upper truss link 814A and 814B.

FIGS. 15B and 15C are diagrams illustrating examples of a truss muscle 950, in accordance with various aspects of the present disclosure. FIG. 15B illustrates a perspective view of the truss muscle 950. As shown in the example of FIG. 15B, the truss support hook 1500 is integrally formed on the truss muscle 950.

The truss support hook 1500 extends outward from the truss muscle 950. The truss support hook 1500 provides a secure engagement point for one of the upper truss links, helping to support the upper truss assembly. A groove 1504 is shown on the side of the truss muscle 950 and is designed to receive an upper truss link, allowing the truss link to fit snugly within the groove, adding additional stability to the structure. As shown in the examples of FIGS. 15B and 15C, the truss muscle 950 includes a through hole 1506 for receiving an upper link connector, such as the upper link connector 1502 described with reference to FIG. 15A. The through hole 1506 may be defined in the center (or substantially center) of the truss muscle 950. The through hole 1506 may be accessible via both a front and a back of the truss muscle 950.

FIG. 15C illustrates a back view of the truss muscle 950. As shown in the example of FIG. 15C, a receiving area 1508 is shaped to accommodate the end of the upper truss link 814B. The receiving area 1508 is contoured to ensure that the truss link is securely held in place, minimizing movement and preventing disengagement during the shelter's use. Additionally, the groove 1504, also visible in this figure, aligns with the upper truss link 814B to provide a stable attachment, ensuring that the truss muscle 950 remains securely connected to the truss links.

The truss muscle 950 may be constructed from a polymer, such as nylon 6, which offers mechanical strength, durability, and resistance to abrasion. Nylon 6 may be desirable due to its flexibility and ability to withstand environmental stresses such as wind and varying temperatures, while maintaining its integrity. The material's combination of strength and flexibility allows it to perform similarly to a well-tuned spring—able to flex under pressure but strong enough to return to its original form.

Still, aspects of the present disclosure are not limited to nylon 6, as various other materials may be used in the construction of the truss muscle 950, depending on specific mechanical and environmental requirements. These materials include, for example, polypropylene, polycarbonate, or acrylonitrile butadiene styrene (ABS).

In some embodiments, the truss muscle 950 may be made from lightweight metal alloys, such as aluminum or titanium, which offer superior strength and corrosion resistance while keeping the overall weight low for ease of assembly and transport. Alternatively, reinforced composites, such as fiberglass or carbon fiber, can be utilized for increased load-bearing capacity and enhanced resistance to wear and deformation, similar to the strength of a bridge reinforced with steel cables.

The flexibility to use a wide range of materials allows the truss muscle to be tailored to the specific needs of different environments and applications. This versatility ensures that the truss muscle 950 can satisfy a variety of performance criteria, from strength and flexibility to weather resistance and cost efficiency.

FIG. 16 is a diagram illustrating an example of a collapsible shelter 1600, in accordance with various aspects of the present disclosure. The collapsible shelter 1600 is an example of the collapsible shelter 800 described with reference to FIG. 8. As shown in the example of FIG. 16, the collapsible shelter 1600 includes flexible rods 850, truss links 814, and a central hub 806, all of which work together to provide a stable and durable structure.

A framework of the collapsible shelter 1600 includes four supporting legs 808, each comprising a hollow upper section 822 and a telescoping lower section 824. These legs 808 provide the primary vertical support for the structure. The telescoping feature allows the legs to extend or retract, contributing to the portability and collapsibility of the shelter. At the top of each leg, a leg bracket 866 and a sliding bracket 864 provide attachment points for the various truss links 812, 814, and 832.

The flexible rods 850 extend from the central hub 806, forming the arched roof structure. These rods are designed to create tension and distribute loads evenly across the roof, improving the shelter's resistance to environmental factors such as wind and rain. The rods are connected to the central hub 806 at mounting points and extend outward to attach to mounting devices at a center point each side. The arched design of the flexible rods also helps maintain the shape of the roof, ensuring that it remains taut.

The perimeter truss links 812 form a horizontal support structure between the legs and are arranged in a scissor-like configuration. The upper truss links 814A and 814B form a pair, one upper truss link 814B of each pair is pivotally connected to the central hub 806. Each pair of upper truss links 814A and 814B is reinforced by the truss muscle 950 to help maintain the tension and stability of the roof structure. The truss muscle 950 provides additional rigidity by exerting a positive lift force between the truss links, ensuring that the roof remains structurally sound and resistant to sagging. For ease of explanation, only one upper truss link pair 814A and 814B, one outer truss link 812, and one leg bracket 866 are labeled in the example of FIG. 16.

The lower truss links 832 extend from the leg brackets 866 to provide further reinforcement to the overall frame. These truss links work in conjunction with the flexible rods and upper truss links to create a balanced and stable structure capable of withstanding various environmental pressures.

FIG. 17 is a diagram illustrating a top-down view of a collapsible shelter 1700, in accordance with various aspects of the present disclosure. The collapsible shelter 1700 is an example of the collapsible shelter 800 described with reference to FIG. 8. As shown in the example of FIG. 17, at the center of the collapsible shelter 1700 is the central hub 806, which acts as the main attachment point for the flexible rods 850 and an upper truss link 814B of an upper truss link pair 814A and 814B. From the central hub 806, the flexible rods 850 extend outward to the center of each side of the collapsible shelter 1700. These rods 850 form a support system for the roof and are designed to maintain the tension and stability of the structure by distributing forces evenly across the roof. The flexible rods 850 also provide the necessary upward curvature for the shelter's roof, allowing the shelter to shed water and resist wind effectively.

The upper truss links 814A and 814B further reinforce the collapsible shelter 1700. These upper truss links 814A and 814B are arranged diagonally across the frame, connecting to respective leg brackets 866 and providing additional support to the roof structure. For ease of explanation, only one upper truss link pair 814A and 814B, one outer truss link 812, and one leg bracket 866 are labeled in the example of FIG. 17. The outer truss links 812, which form a perimeter around the entire shelter frame, connecting to respective leg bracket 866 or sliding leg brackets 864 at the corners. This perimeter truss system helps ensure the shelter maintains its overall shape and rigidity.

In some examples, a process for setting up the collapsible shelter begins by positioning the group of legs, ensuring they are securely standing. Each leg includes a fixed leg bracket and a sliding leg bracket. The outer truss links are already attached between each pair of legs, providing stability and forming the shelter's perimeter. The legs may be expands such that the outer truss links expand outward and the upper truss links rise upward to form a roof structure.

Next, the flexible rods may be attached to complete the roof structure. Each flexible rod should be secured by attaching its first end to a respective flexible rod mounting point, which is already affixed to an outer truss link. The flexible rod mounting point includes a cylindrical mounting point defined at an upward angle to facilitate secure attachment. Once the first ends of the flexible rods are in place, attach the second end of each flexible rod to its corresponding socket on the center hub, which is positioned at the peak of the shelter. Before or after attaching the flexible rods, the cover may be placed over a roof structure of the shelter.
