The jumping mat includes a substantially horizontal jumping region between two arcuated shaped jumping regions at opposing ends of the horizontal jumping region when connected to the frame. The frame may include two opposing ends formed from a pair of substantially parallel arcuated tubes each having a substantially vertical end, a substantially horizontal end, and a mid-point along its curved length, a support bar connecting the arcuated tubes at their substantially vertical ends, a pair of end footings, wherein each end footing is connect to the support bar and to the mid-point of one of the arcuated tubes, and a pair of side footings, wherein each side footing is connected to a leg of one of the end footings and to one of the arcuated tubes at its substantially horizontal end.
This application is a Continuation-in-Part of U.S. patent application Ser. No. 14/014,294, filed Aug. 29, 2013, which claims priority to U.S. Provisional Application Nos. 61/694,624 filed Aug. 29, 2012, and 61/864,980 filed Aug. 12, 2013, the entire contents of which are each incorporated by reference herein as if each is being set forth in its entirety.
BACKGROUND OF THE INVENTIONPresently, trampolines have consisted of a single, flat jumping mat attached under the tension of elastic springs or cords to a rigid frame, such that a subject can bounce up and down on the jumping mat. While there have been many improvements to the design and quality of materials of trampolines, all these advancements have retained the general design of the jumping mat surface being on a single plane.
It is well known that trampolines introduce a risk of injury to the subject or subjects jumping on them. For example, subjects can inadvertently launch towards the perimeter of the trampoline, possibly falling into the trampoline framework, or even falling entirely off the trampoline, resulting in injury. In other examples, a subject can inadvertently slip through the trampoline in the region of the elastic springs or cords connecting the jumping mat to the frame, also resulting in injury.
To combat this, padding is typically used to cover the springs and frame components at the perimeter of the jumping mat. Additionally, netting is often suspended by poles extending generally upward from the trampoline frame to stop a subject from falling outside of the framework. Unfortunately, while these safety measures help to decrease the number of injuries, they significantly detract from the experience of trampoline use.
Thus, there is a need in the art for a trampoline system that enhances the trampoline experience while still improving safety of use. The present invention satisfies this need.
SUMMARY OF THE INVENTIONThe present invention relates to a trampoline system. The trampoline includes a frame, a jumping mat and elastic means for connecting the jumping mat to the frame, wherein the jumping mat includes a substantially horizontal jumping region between two arcuated shaped jumping regions at opposing ends of the horizontal jumping region when connected to the frame. In one embodiment, the frame includes four side footings and two end footings. In another embodiment, the frame includes at least two cross-bar supports running substantially perpendicular to the length of the jumping mat. In another embodiment, the frame includes at least four cross-bar supports running substantially perpendicular to the length of the jumping mat. In another embodiment, the frame includes at least five cross-bar supports running substantially perpendicular to the length of the jumping mat. In another embodiment, at least one of the cross bar supports runs substantially perpendicular to the length of the jumping mat and underneath about the middle of the substantially horizontal jumping region. In another embodiment, the substantially horizontal jumping region is between 1 and 10 feet in length. In another embodiment, the substantially horizontal jumping region is between 2 and 20 feet in length. In another embodiment, the substantially horizontal jumping region is about 5 feet in length. In another embodiment, the substantially horizontal jumping region is about 10 feet in length.
The present invention also relates to a curved trampoline frame end structure. The frame end includes a pair of substantially parallel arcuated tubes each having a substantially vertical end, a substantially horizontal end, and a mid-point along its curved length, a support bar connecting the arcuated tubes at their substantially vertical ends, a pair of end footings, wherein each end footing is connect to the support bar and to the mid-point of one of the arcuated tubes, and a pair of side footings, wherein each side footing is connected to a leg of one of the end footings and to one of the arcuated tubes at its substantially horizontal end. In an alternative embodiment, the frame end includes a pair of substantially parallel arcuated tubes each having a substantially vertical end, a substantially horizontal end, and a mid-point along its curved length, a support bar connecting the arcuated tubes at their substantially vertical ends, a pair of end footings, wherein each end footing is connect to the mid-point and to the substantially vertical end of one of the arcuated tubes, and a pair of side footings, wherein each side footing is connected to a leg of one of the end footings and to one of the arcuated tubes at its substantially horizontal end. In one embodiment, the frame end further includes a cross-bar connecting the pair of side footings. In another embodiment, the frame end further includes a cross-bar connecting the pair of end footings. In another embodiment, the leg of the end footing to which the side footing is connected to forms the connection to the mid-point of one of the arcuated tubes.

Throughout this disclosure, various aspects of the invention can be presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual numbers within that range, for example, 1, 2, 2.7, 3, 4, 5, 5.3, 6 and any whole and partial increments therebetween. This applies regardless of the breadth of the range.
The present invention includes a trampoline system that allows a subject to bounce on both a central, substantially horizontal surface area, and a surrounding wall that is continuous with the central surface area and positioned at an angle about the perimeter of the central surface area.
As shown in
As contemplated herein, jumping mat 30 includes at least two primary jumping surfaces. The first jumping surface 31 is substantially horizontal and resembles the basic, single plane mat of a typical trampoline assembly. The second jumping surface 32 forms a wall positioned at an upward angle 33 from first jumping surface 31. Second jumping surface 32 extends generally from the perimeter of first jumping surface 31 at angle 33 suitable for propelling a subject generally upward and/or back into the vicinity of first jumping surface 31. For example, in one embodiment, angle 33 may be any angle between substantially horizontal and substantially vertical. In another embodiment, angle 33 may be between 1° and 90°. Preferably, angle 33 is between 25° and 50°, more preferably between 30° and 40° and even more preferably, angle 33 is about 35°. It should be appreciated that there is no limitation to angle 33, provided that it allows second jumping surface 32 to be positioned tangentially from the plane of first jumping surface 31.
While
In other embodiments, first jumping surface 31 is not fully surrounded by second jumping surface 32, but instead simply includes one or more jumping surfaces 32 that are continuous with jumping surface 31, or alternatively, adjacent to jumping surface 31. For example, jumping surface 31 may be substantially rectangular, and include two jumping surfaces 32 located at opposing ends of jumping surface 31. In such embodiments, the trampoline system may resemble a “half-pipe” with two walls tangentially angled upward from jumping surface 31. In such embodiments, frame 20 can be constructed such that the angle 33 of one or more jumping surfaces 32 can be adjustable, for example, such as by using telescoping frame tubing, sliding clamps, locking spring pins or rigid pins, sliding rails, and any combination thereof.
Depending on the desired shape and positioning of first and second jumping surfaces 31 and 32, jumping mat 30 can be constructed from a single piece of jumping mat material, or it can be constructed from multiple pieces of jumping mat material attached together to form a continuous jumping mat surface. For example, when trampoline system 10 is circular, as illustrated in
As shown in
The mat material of first and/or second jumping surfaces 31 and 32, as well as reinforcement strip 37, may be any standard trampoline mat material as would be understood by those skilled in the art, such as polypropylene or nylon or other durable fabric materials, which may also have UV resistant properties or coatings.
As shown in
Alternatively, frame 20 may be designed to attach to an existing, standard trampoline. For example, frame 20 may include upper support ring 23, support arms 25 and base component 26, and further include clamps or other attachment components attaching some of support arms 25 to the existing trampoline framework, such that the existing trampoline framework effectively becomes or replaces lower support ring 24. Then by replacing the existing standard trampoline mat with jumping mat 30 of the present invention, a subject can effectively convert their existing trampoline into the trampoline system of the present invention. Accordingly, trampoline system 10 of the present invention may be provided as an all-inclusive trampoline system, or it may be provided as a “conversion kit” for transforming an existing trampoline into the trampoline system of the present invention.
Elastic attachment means 40 are used at both upper and lower mat attachment areas 21 and 22, and may include any mechanical component or mechanism that provides an elastic attachment of jumping mat 30 to frame 20 at upper and lower mat attachment areas 21 and 22. For example, elastic attachment means 40 may include the use of metal springs, rubber cords or straps such as bungee cords, and the like, as would be understood by those skilled in the art. For example, jumping mat 30 may include a series of loops and/or secured metal rings at its perimeter that springs can hook on to. Similarly, upper and lower support rings 23 and 24 may include holes or knobs for the springs to also hook into or onto to provide the proper tension and spring bounce to jumping mat 30 when a subject is jumping on it.
In yet another exemplary embodiment of the present invention, the trampoline system may include two adjacent jumping mats, wherein the mats are at different planes and the second mat surrounds the entire perimeter edge of the first mat. For example,
Trampoline 50 may include a padding system 57 at the top perimeter edge, covering the springs connecting second jumping mat 55 to upper support ring 52. This padding system may be a standard padding, or it may be a padding wrap system as illustrated in
In yet another exemplary embodiment of the present invention, the trampoline system may include a single jumping mat, wherein the jumping mat is curved at one or more ends, creating an arcuated shaped surface that present multiple jumping planes. For example, as shown in
It should be appreciated that the framing for a stand-alone halfpipe trampoline system must be structured to withstand not only the force of a jumper jumping on the mat, but also the force of the spring tension pulling the framing inwardly into the jumping regions when the mat is assembled onto the frame via the springs. Such framing is particularly challenging due to the need to keep a sufficient space underneath the mat free of any framing components that could interfere with a jumper applying a downward force against the jumping mat. As shown in
As shown in
Any of the trampolines described herein may further include a standard padding system to cover the springs, or they may include a wrapping padding system 87, shown in greater detail in
Cushion 92 may be any cushioning material understood by those skilled in the art. In one embodiment, cushion 92 is a foam material. In another embodiment, cushion 92 is a balloon composed of PVC, nylon or an elastic material that can be filled with a gas, such as air, or even water. Cushion 92 may come in multiple pieces or sections. The actual number of cushion 92 sections will be dependent on the particular shape and size of the trampoline jumping mat perimeter needing the padding system of the present invention.
Liner 91 may provide a protective layer between the springs and/or frame components of the trampoline and cushion 92, if desired. Liner 91 may be a single layer or a multi-layer, and may be composed of any material desired. Preferably, liner 91 is composed of PVC, nylon or other lightweight material that resists puncture. In some embodiments, liner 91 lays on top of the springs and/or framing components of the trampoline. In other embodiments, liner 91 is at least partially attached to at least one region of the springs and/or framing components of the trampoline. In other embodiments, liner 91 is attached to cover 90, such that cushion 92 is encased within an interior region formed between cover 90 and liner 91. In still other embodiments, liner 91 is attached to jumping mat 82 and cover 90 at attachment region 93.
Attachment region 93 serves to securely anchor cover 90 and optionally liner 91 of wrapping padding system 87 to jumping mat 82. Attachment region 93 may be permanently secured or it may be detachably secured. In one embodiment, cover 90 is permanently attached to jumping mat 82 via stitching cover 90 at region 97 to the perimeter of jumping mat 82, such that region 97 of cover 90 overlays V-ring straps 98. In another embodiment, region 97 of cover 90 may be detachably secured to the perimeter of jumping mat 82 via Velcro®, snaps, buttons, zippers, ties or any other mechanism that allows for cover 90 to be securely attached and subsequently detached to jumping mat 82.
As contemplated herein, the trampoline systems of the present invention not only increases the user experience of multiple jumping surfaces on two or more planes, but it also enhances safety of use. For example, when a subject inadvertently launches towards the perimeter of the first jumping surface, the subject may “bounce” off the second jumping surface and be propelled back into the vicinity of the first jumping surface, instead of falling into the trampoline framework, the springs or even falling entirely off the trampoline. As the length of the wall of the second jumping surface is increased, the likelihood of a subject being able to bounce over the second jumping surface wall decreases, thereby reducing the likelihood that a subject will inadvertently contact the framing material, attachment springs, or even fall all the way out of the trampoline.
Further, the trampoline system of the present invention may additionally include any standard safety components as understood by those skilled in the art, such as soft mat coverings to cover the springs or cords, or netting extending above the upper ring of the frame. For example, because upper support ring is positioned above the height of the first substantially horizontal jumping surface, such netting would not need to extend very far beyond the height of the upper support ring of the frame. Alternatively, the netting can be shaped as a dome over the jumping mat, where the dome is formed by sturdy or flexible poles anchored to the upper support ring and arching overtop the jumping mat.
