Description

A SPRUNG WALL ARRANGEMENT FOR A TRAMPOLINE
BACKGROUND OF THE INVENTION
THIS invention relates to a sprung wall arrangement for a trampoline.
Typical trampolines comprise a frame for supporting a strong fabric sheet using a plurality of springs. In one version, the frame may be arranged to cover or surround a pit dug into the ground so as to define a sunken trampoline, and in another version, the frame may be supported above the ground so as to define a raised trampoline. Both versions, however, have a number of disadvantages including the risk of people landing on the springs, on the frame or on the ground. There is also a relatively limited range of exercises or movements that can be performed on the trampoline.
It is an aim of the present invention to address these disadvantages. SUMMARY OF THE INVENTION
According to the invention there is provided a sprung wall arrangement for a trampoline, the trampoline comprising a substantially flat frame for horizontally supporting a fabric sheet using a plurality of springs, the sprung wall arrangement comprising:
a plurality of frame elements that are arranged around the frame of the trampoline;
a fabric sheet that defines a wall around the trampoline; and
a plurality of sets of springs, each set being arranged to connect the fabric sheet of the wall to one of the plurality of frame elements.
In an example embodiment, each frame element comprises a connecting post, the connecting post being arranged to extend upwardly so as to define an angle between itself and the trampoline.
Advantageously, the fabric sheet is connected to the connecting posts so that the fabric sheets are held at an angle with respect to the trampoline.
Each frame element may be connected or connectable to the flat frame.
In addition, each frame element may include a support leg for supporting the connecting post.
The angle between each connecting post and a plane defined by the trampoline may be approximately 45°.
The angle between the fabric sheet and a plane defined by the trampoline may also be approximately 45°. The fabric sheet of the trampoline is typically polygonal so as to define a plurality of sides and so the fabric sheet of the sprung wall is also typically formed from a plurality of panels that correspond to the sides of the polygonal fabric sheet of the trampoline.
The bottom of the sprung wall may be arranged to cover the springs of the trampoline.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows a side perspective view of a sprung wall for a trampoline according to an example embodiment;
Figure 2 shows a detailed side view of the sprung wall taken along line 2-2 shown in Figure 1 ; and
Figure 3 shows a side view of a sprung wall for a trampoline according to a further example embodiment.
DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to Figures 1 and 2, a sprung wall arrangement 10 for a sunken trampoline 12 is shown. The trampoline 12 comprises a substantially flat frame 14 inserted into an opening or pit in the ground 15 for horizontally supporting a fabric sheet 16 using a plurality of springs, indicated generally by arrows 18. For example, the frame 14 may surround the pit dug into the ground.
In one embodiment, the substantially flat frame 14 is polygonal to provide a base to which the fabric sheet of the trampoline is secured. The frame 14 may be manufactured from angle iron.
The sprung wall arrangement 10 comprises a plurality of frame elements 2OA to 2OH that are arranged around the frame 14 of the trampoline 12. Each frame element 2OA to 2OH comprises a connecting post 22 as shown in Figure 2. The connecting post 22 is arranged to extend upwardly so as to define an angle θ between itself and a plane defined by the trampoline/ground. Preferably, the angle θ is approximately 45°.
The connecting posts 22 may be connected or connectable to the frame 14. For example, and as shown in Figure 2, the connecting post may be bolted to the frame 14. The connecting posts 22 may also be secured to the frame 14 by any other suitable means, for example by welding.
In an alternate embodiment, each frame element 2OA to 2OH may include a support leg (not shown) for supporting the connecting post. The connecting post 22 and support leg may be combined into one section.
A fabric sheet 26 is arranged to define a wall 28 around the trampoline 12. Typically, the fabric sheet 16 of the trampoline 12 is polygonal so as to define a plurality of sides. Accordingly, the fabric sheet 26 of the sprung wall arrangement 10 defines a plurality of panels 28A to 28H that are secured together, e.g., stitched or welded together, with the panels 28A to 28H corresponding to the sides of the polygonal fabric sheet 16 of the trampoline 12.
The fabric sheet 26 may be made of a woven trampoline material, a coated, woven fabric that may be a PVC coated polyester fabric, or any other suitable material
Advantageously, the bottom of the sprung wall 28 is arranged to cover, or at least partially, cover as shown in Figure 2, the springs 18 of the trampoline 12.
The sprung wall arrangement 10 further comprises a plurality of sets of springs 3OA to 3OH, each set being arranged to connect the fabric sheet 26 of the sprung wall 28 to one of the plurality of frame elements 2OA to 2OH. As shown more clearly in Figure 2, this configuration allows each set of springs, in this case set 3OA, connected to the fabric sheet 26 of the sprung wall 28 to define an angled plane.
In the illustrated embodiment the springs are in the form of coil springs, however the springs may take another form such as elastic bands, for example.
Turning now to Figure 3, a sprung wall arrangement 40 for a raised trampoline 42 is shown. The trampoline 42 comprises a substantially flat frame 44 supported on a plurality of legs 46A, 46B, 46C and 46D1 the frame 44 being arranged to horizontally support a fabric sheet (not shown) using a plurality of springs (also not shown).
The sprung wall arrangement 40 comprises a plurality of frame elements 48A, 48B, 48C and 48D that are arranged around, and fitted to, the frame 44 of the trampoline 42. Each frame element 48A to 48D is arranged to extend upwardly so as to define an angle θ between itself and a plane defined by the trampoline 42. Preferably, the angle θ is approximately 45°. It will be appreciated, that in this configuration the angled plane defined by each set of springs connected to the fabric sheet of the sprung wall may also be 45°.
A fabric sheet 50 is arranged to define a wall 52 around the trampoline 42. The fabric sheet 50 is substantially similar to the fabric sheet 26 described above, and will thus not be repeated here.
Advantageously, a support ring 54 may be fitted to the outside of the plurality of frame elements 48A, 48B, 48C and 48D so as to support the sprung wall arrangement 40. In one example embodiment, the support ring 54 will be fitted to the upper ends of the plurality of frame elements 48A, 48B, 48C and 48D. In one embodiment, a ladder 56 may be attached to the support ring to enable a user of the trampoline to climb over the sprung wall arrangement in order to use the trampoline.
In another embodiment, instead of using the ladder 56 to enter the sprung wall arrangement, a gap of about 300mm is left between the bottom of the sprung wail 28 and the horizontal fabric sheet 16 so that a user can enter the arrangement by crawling under the sprung wall 28.
The present invention thus provides a sprung wall arrangement that can be relatively easily fitted to an existing trampoline, and that greatly extends the versatility, safety and usability of the trampoline.
