BACKGROUND OF THE INVENTIONThe present invention relates to a tent and more particularly to a foldable or collapsible tent. For novice campers and camping families, among others, foldable tents are a popular alternative to conventional assemble-to-use tents. These tents are commonly referred to as “instant tents,” “one-touch tents” or “pop-up tents.” Foldable tents are typically sold with a frame assembly and tent fabric permanently attached to each other, i.e., preassembled. Erecting and collapsing the tent is easy and less time consuming than conventional assemble-to-use tents because the frame assembly and tent fabric are collectively opened and folded. The frame assembly usually includes a single central hub and a plurality of poles pivotally attached to the hub to provide a stable tent structure. These types of instant tents are particularly advantageous because a minimal number of poles, typically four, are required and thus erecting and collapsing the instant tent is quite simple. Although convenient for the user, there are several disadvantages for instant tents in the prior art.
For example, a large amount of stress is exerted on the frame assembly due to the tension from the tent fabric. These stresses are often transferred to and concentrated on the single central hub where the poles are interconnected, especially when a wind force is exerted on the tent. Thus, there is risk of damage or even failure of the central hub.
Also, the size of instant tents in the prior art today are limited because stability of the structure is compromised with longer poles required for larger instant tents. Therefore, even though there is great interest for bigger tents (often including separate rooms), this cannot be achieved with an instant tent today. Instead, larger tents that could accommodate many people are of the conventional type which requires the user to separately assemble the poles and then attach the poles to the tent fabric for set up, and detach the poles from tent fabric and disassemble the poles to store and transport.
Another disadvantage of instant tents of the prior art is that head room is limited. The central portion of the instant tent where the central hub is located serves as the apex of the tent. Even though cabin instant tents attempt to solve this problem, the poles are positioned downwardly and the ceiling height decreases from the central portion of the tent. Thus, head room is still limited at radially outer portions of the tent.
As another example, instant tents in the prior art are limited in shape. They are either dome shape or a single rectangular cabin. The use of a single central hub also limits the overall configuration of the instant tent because the overall length of the tent is restricted by the length of the poles which can securely extend from the central hub. Therefore, a tent with a more elongated configuration or other configurations cannot be achieved.
Instant tents today also pose problems with folding the tent into a relatively short and compact state. The folded length of the tent as well as the volume of the tent is dictated by the sections of the poles which are connected to the central hub and because those pole sections are usually elongated to increase the overall volume of the tent in the open configuration, the instant tent is relatively long when folded.
Another problem with instant tents today is the lack of an integral rain fly that provides sufficient head room for the user.

The tent 300 is shown with features such as doors having slide fasteners (zippers), ground flaps and vents, however, the tent could be constructed with more or less features than shown. For example, the tent could be constructed with an impermeable roof, permeable walls and without a floor as a screen house. Screen houses are particularly useful when one desires ample ventilation and/or shade while preventing bugs or mosquitoes from entering living quarters or entertaining space. Also, each of the pivoting joints and auxiliary hubs 313 are covered with a fabric casing which protects the tent fabric 322 from damage when the tent is folded, but could be constructed without the fabric casings.

Alternative embodiments of frame assemblies 140, 150 are shown in
In all of the embodiments of the tent of the present invention, the tent fabric is intended to remain coupled to the frame assembly at all times, including when the tent is folded. The frame assemblies are shown without the tent fabric for purposes of clarity.
The hubs 315, 313, 311, 211, 213 and 111 of the embodiments of the frame assemblies described above could be any tent hub known in the art, for example, the hubs shown and described in U.S. Pat. Nos. 7,861,736 and 8,448,656 as well as the '589, '517 and '396 Applications, which are incorporated by reference in their entireties.
The tent fabric 322, 222 of the embodiments is shown with features such as doors, openings, windows, vents and permeable portions, however, the tent fabric could be modified to include more or less features. For example, a tent fabric having a roof, eaves, side walls partially constructed of mesh and no floor could be utilized to form a screen house, or a tent fabric having only a roof and additional fabric along the leg assemblies could be utilized to form an open shelter. Also, the tent fabric 322, 222 could be coupled to the respective frame assemblies by a variety of means including hooks and fabric sleeves extending from the tent fabric. Other means such as button fasteners, hook-and-loop fasteners could be used as well.
In the present embodiments the poles of the instant cabin tents are constructed of a rigid tubular steel having a diameter between 14.5 mm and 16 mm. The upper poles of the instant dome tents are constructed of fiberglass reinforced plastic (FRP) and the lower poles are constructed of a rigid tubular steel. Other materials such as other metals (e.g., aluminum), metal alloys, other polymers and composite materials or any combination thereof could be used, and different sizes of poles could be used depending on desired strength without departing from the spirit and scope of the invention. Also, each of the pivoting joints and hubs could be covered with a fabric casing to protect the tent fabric from damage when the tent is folded.
For the instant dome tents that utilize a central hub having poles pivot upward with respect to the hub, if necessary, the tent could include an adjustable loop assembly 620 as shown in FIG. 21 of U.S. Pub. No. 2012/0318316 and described therein.
The overall configuration of the embodiments described above allow for larger instant tents with increased headroom. In the present embodiments, the angles (with respect to a horizontal plane) at which the central roof poles and lower roof poles extend are much less than the angle at which a continuous pole of comparable instant tents of the prior art extends, and thus, more volume and head room are provided. Thus, the larger tents could be provided with interior dividers to form separate rooms and/or vestibules and multiple entrances. The frame assemblies shown in the drawings are easy to set up and fold, while the various embodiments of the frame assemblies could be used with a variety of tent fabrics pre-assembled to the frame assembly to form, for example, an enclosed instant tent, an open instant shelter or an instant screen house.
Also, the stresses in tent structures are mostly concentrated on the upper or roof portion of the frame assembly where the poles are closer to a horizontal position. For foldable frames of the prior art which utilize only a single central hub and have continuous upper poles extending from the central hub to the upper corners of the tent, those stresses are concentrated on the central hub and upper poles. This requires the use of a substantially large hub and upper poles with larger diameters to accommodate for those stresses. Even so, damage to or failure of the central hub is possible. For the tents of the present invention shown in
Moreover, in the embodiments shown, the tent is capable of being folded into a more compact state than a comparable instant tent of the prior art. The tent is capable of being folded into a compact state despite the large volume of the tent in the open configuration which can accommodate a large number of people. This is because the overall folded length of the tent is dictated by the length of the upper roof pole 114, 221, 321 which covers a partial length of the roof. In contrast, roof poles used for instant tents in the prior art with single central hubs covers the entire diagonal length of the roof spanning from the center to corner. Almost invariably, the length of the lower roof pole 113, 212, 312 whether retracted or not, is less than the length of roof poles of comparable single hub instant tents in the prior art. Thus, the compact folded instant tents of the present invention are advantageous for storage and transport.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
