Abstract

A trampoline having one or more seat structures supported on a surrounding support frame with which a jumping surface is resiliently stretched. Each seat is carried by the surrounding support structure and is secured in plane by attachment to a trampoline leg that supports the jumping surface and the surrounding support frame. The seat structures are attachable to many known trampolines and provide seating outside of the jumping surface of the trampoline so that people can sit on the seats even while other people are jumping on the jumping surface and without obstructing the jumping surface.

BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to trampolines.
Trampolines comprising a flexible material forming a jumping surface tautly and resiliently stretched within a supporting framework are well known.
Trampolines have proven very popular as exercise devices and for entertainment purposes.
Some trampolines are installed to be at ground level with a hole in the ground over which the jumping surface is stretched between a surrounding frame and with spaced resilient grippers securing the jumping surface to the frame.
Trampolines also come in different sizes, with the jumping surface ranging from the small areas of mini tramps for use by a single jumper to much larger trampolines with jumping surfaces that will permit as many as six, eight or even more jumpers to perform simultaneously.
It is believed that the majority of these commonly trampolines in use are above ground trampolines with a jumping surface supported on legs ard of a size that will safely allow two or even up to four jumpers to perform on the jumping surfaces at the same time. If more than the safely allowed number of jumpers are desirous of jumping, it becomes necessary for the jumpers to take turns. This generally means that people are jumping on the jumping surface for a period of time and then, after completion of their jumping, climbing down off the trampoline. At the same time other people who have waited for a turn to jump are often climbing onto the trampoline and preparing to jump.
The rotation of jumpers from ground to jumping surface and back to ground often results in collision between jumpers and injuries resulting from falls. In addition, time that could be spent on the jumping surface is often wasted as the rotating jumpers mount and dismount from the trampoline jumping surface.

BRIEF SUMMARY OF THE INVENTION

OBJECTS OF THE INVENTION

A principal object of the invention is to provide a trampoline on which one or more persons can jump on a jumping surface while another person or other people are resting on the trampoline support structure off the jumping surface and out of the way of the person or persons jumping.
Another object of the present invention is to provide a trampoline that will allow jumpers to rotate on and off a jumping surface and on and off seating provided on the support frame for the trampoline.
Yet another object is to provide a trampoline having an easily installed and easily removed seat, or a plurality of such seats, that will support persons sitting thereon outside of the periphery of the trampoline frame. The seat or seats will support such person or persons even as another person, or a plurality of people are jumping on the jumping surface of the trampoline.

FEATURES OF THE INVENTION

To achieve the aforementioned objects, the trampoline of the invention has the usual, tautly stretched jumping surface and surrounding support frame. Resilient means, most commonly, coil springs. secure the periphery of the jumping surface to the surrounding support frame and legs extend from the support frame to hold the frame and jumping surface in a stable condition and at a desired height, above ground or a floor.
At least one seat structure is attached to the surrounding support frame and a trampoline leg, with a seat surface positioned outwardly of the surrounding support frame and outside the outer periphery of the jumping surface.
Preferably, the seat structure is readily secured to the surrounding frame and a trampoline leg. It will be apparent that more than one seat assembly can be attached to the surrounding support frame and a support leg to allow a number of persons to sit on the seat surface while one or more persons are jumping on the jumping surface.
Each person sitting on a seat surface can rest his or her feet on the padded cover commonly provided over the top of the resilient means (springs). The sitting person's foot will not adversely affect operation of the resilient means and will not extend onto the jumping surface to limit the safe jumping surface area available to the person or persons jumping.
The seat structure preferably includes a rigid, strong seat base having a padded upper seating surface.
A support bar has one leg that extends across the seat base bottom from a front edge to a rear edge of the seat base. Another leg of the support bar extends downwardly from a front edge of the seat. Hooks appropriately placed along the length of the downwardly extending support bar hook over the surrounding support frame and hold the seat at a desired seating height above the top of the jumping surface. The seat base is then cantilevered outwardly of the jumping surface.
Clamping structure at the bottom of the downwardly leg of the support bar secures the seat assembly to a depending trampoline leg member and holds the hooks securely on the surrounding support frame.
Additional objects and features of the invention will become apparent to persons skilled in the art to which the invention pertains from the following detailed description and drawings.

DETAILED DESCRIPTION

Referring Now to the Drawings
In the illustrated preferred embodiment of the invention, the trampoline, shown generally at 10, includes a tautly stretched, flexible, durable, jumping surface 12. While the outer periphery of the jumping surface of different trampolines may take different shapes, the outer periphery 14 of the jumping surface shown at 12 is circular.
Jumping surface 12 is connected by springs 16 spaced around the periphery to a surrounding support frame 18. The number of springs 16 attached between the jumping surface and the surrounding support frame 18 and the size of the springs is shown to be that required to hold the jumping surface 12 in a taut condition.
The surrounding support frame 18 (here shown to be of tubular metal construction) is mounted on spaced apart, U-shaped trampoline legs 20. The legs support the jumping surface and surrounding frame held above ground or floor at a desired height. The U-shaped trampoline legs 20 have spaced apart upright members 22 and 24 secured at their upper ends to the surrounding support frame and interconnected at their other ends by a ground or floor engaging member 26.
In conventional fashion, a padded cover 28 overlies the surrounding support frame 18, and the springs 16 to protect jumpers against injuries that could occur if they engage the frame or springs, while jumping.
As shown in FIG. 1, a pair of seat structures 30 are supported by the surrounding support frame 18 to provide seating for persons not currently jumping on the jumping surface 12.
Each seat structure 30 includes a rigid seat base 32 of desired width. The seat base may be wide enough to seat one adult, or two children, for example. Alternatively, the seat base may have another desired width.
The upper surface of the seat base 32 has padding 34 thereon and a cover 36 fitted over the padding 34 is secured to a bottom surface of the seat base with staples 40. Thus, the seat base preferably has a cushioned upper surface although it will be apparent that padding and cover are optional.
An L-shaped support bar 44 has one leg 36 extending centrally across the bottom surface 38 of the seat base 32. Transversely extending plates 48 and 50 wielded to opposite ends of the leg 46 and screws 54, are inserted through washers 56 and holes 58 in opposite ends of the transverse plates 48 and 50, and are secured into the seat base 32, thereby securing leg 46 to the seat base 32. The leg 46 is positioned to extend from beneath a front edge 60 of the seat base 32 to beneath a rear edge 62 of the seat base. The leg 46 is mounted to extend across the seat base centrally between opposite ends 66 and 68 of the seat base.
The other leg 70 of support bar 44 extends downwardly from the end of leg 46 beneath the front edge 60 of the seat base 32.
A diagonal brace 74 extends from the free end of leg 46 to intermediate the length of leg 70 to strengthen the seat structure 30.
A plate 78 is fixed to a front surface 78 of leg 70 and a pair of spaced apart hooks 80 and 82 extend from plate 78. Hooks 80 and 82 are sized to fit snugly over the surrounding support frame 18.
An anchor plate 84 is fixed to a lower end of leg 70 and extends outwardly beyond both sides of the leg.
Holes 88 and 90, through the anchor plate 84 receive the threaded ends 92 and 94 of a U-clamp 96. U-clamp 96 is sized to straddle a vertical leg 22 or 24 of a trampoline leg 20 and to then have its ends 92 and 94, respectively inserted through the holes 88 and 90. Lock washers 100 are inserted on the ends 92 and 94 and nuts 102 are threaded onto the ends 92 and 94 to pull the U-clamp tightly against the trampoline leg and to keep the hooks 80 and 82 from disconnecting from the surrounding support frame 18.
A cushioned pad 104 may be fitted over the upper end of leg 70, above the hooks 80 and 82 so that a jumper otherwise engaging the upper support leg will not be seriously hurt.
With the seat structure 30 positioned and mounted as described, the front edge of the seat base is above a portion of the surrounding support frame. The seat base is cantilevered away from the surrounding support frame and the jumping surface while being supported by the surrounding support frame.
