Description

TRAMPOLINE ROOF

FIELD OF THE INVENTION [0001] The invention relates to a roof for a trampoline. In particular, the invention relates, but is not limited, to a soft roof to cover the top of a trampoline.

BACKGROUND TO THE INVENTION [0002] Reference to background art herein is not to be construed as an admission that such art constitutes common general knowledge.

[0003] Trampolines have been around for recreational and sporting purposes for a number of years. More recently, particularly in relation to recreational trampolines, safety nets have been incorporated to contain a user in a space above the trampoline and to prevent injury from that user falling off the trampoline or landing on the frame of the trampoline.

[0004] Many trampolines are left outdoors, so roofs are sometimes provided to provide shade and to give the feeling of a tent or cubby house. Typically such roofs are substantially flat and not well suited to weathering rain. A known problem is for water to collect on the roof and create a pool in the middle. If there is sufficient rain this can damage the roof as it is unable to support the weight of the water and can rip or tear.

[0005] In an effort to overcome these issues some trampoline roofs have rigid support members, such as aluminium or fibreglass struts, to support the roof. These roofs are typically dome shaped. However, the hard elements of the support structure can cause injury to any user who jumps high enough to hit the supports. Furthermore, it has been known for some users, typically younger children, to try to grab onto the supports when jumping. This can damage the support structure and can result in injury to the trampoline user, or even bystanders.

[0015] Further features and advantages of the present invention will become apparent from the following detailed description.

BRIEF DESCRIPTION OF THE DRAWINGS [0016] By way of example only, preferred embodiments of the invention will be described more fully hereinafter with reference to the accompanying figures, wherein:

[0017] Figure 1 illustrates a perspective view of a trampoline with a trampoline roof;

[0018] Figure 2 illustrates a close-up cross sectional view illustrating the trampoline roof being attached to a trampoline pole; and [0019] Figure 3 illustrates a close-up cross sectional view illustrating the trampoline roof being attached to a trampoline pole in a different manner.

DETAILED DESCRIPTION OF THE DRAWINGS [0020] Figure 1 illustrates a trampoline 10 having a frame 100, spring members 300 in the form of leaf springs supporting a mat 200 above frame 100, a safety net 400 surrounding the mat 200, poles 150 extending above the mat 200, and a trampoline roof 600.

[0021] The roof 500 has a top 530 and sides 540 which are substantially perpendicular to the top 530. The sides 540 surround the perimeter of the top 530. The roof 500 is supported by poles 150 and covers the top of the trampoline 10 defining a chamber above the mat 200 and within the safety net 400.

-52018264069 12 Nov 2018 [0022] The roof 500 has a plurality of alternating apexes 510 and troughs 520 located In the top 530. The apexes 510 extend radially around the roof 500 In a substantially horizontal plane, The troughs 520 extend radially around the roof 500 at an incline to the apexes 510. Each apex 510 corresponds to a pole 150, extending substantially perpendicularly between opposite poles 150.

[0023] Each apex 510 is formed by two substantially triangular pieces of cover material at an angle to each other along the apex 510. Each apex 510 is connected to adjacent apexes via trough 520. The sides 540 are shaped to form the apexes 510 and troughs 520 in the top 530. Particularly, each side 540 has a bottom edge, two side edges, and a top edge, wherein the top edge is formed from two inwardly inclined segments forming the trough 520. The two side edges are higher than the bottom of the trough 520 forming the apexes 510. The apexes 510 meet in central region 512 of roof 500 which, in a preferred form, is reinforced.

[0024] Although not apparent from figure 1, each apex 510 has a line member in the form of an elastic cord 550 which supports the apex 510 and prevents collapse of the roof 500. An end of the elastic cord 550 can be seen in figures 2 and 3. The elastic cord 550 is received in a sleeve of a shell portion of the roof 500 and is tensioned between the poles 150 to provide a supported, yet soft and resiliently flexible, roof 500. The elastic cords 550 can extend from a respective pole 150 to the central region 512 or, alternatively, between two opposed poles 150 via the central region 512.

[0025] Figure 2 illustrates an upper portion of a pole 150 where the roof 500 is attached pole 150. The roof 500 is also shown in cross section, revealing the elastic cord 550 surrounded by a shell 502. Preferably regions of the shell 502 around the pole 150 are reinforced for added strength and wear resistance. In the example shown in figure 2, the elastic cord 550 of the roof 500 is affixed to a fixing 152 of the pole 150. The elastic cord 550 then extends along a sleeve

-62018264069 12 Nov 2018 portion of the shell 502 up the pole 150 to an upper end 154 of the pole 150 to the central region 512 of the roof 500 (not shown in figure 2). Connection of the elastic cord 550 to the pole 150 tensions the roof 500 as shown in figure 1. Without proper tensioning the roof 500 would collapse and fall in on itself.

[0026] Figure 3 illustrates a different method of attaching the roof 500 to a pole 150, which is better for retrofitting to existing poles 150 that do not have the necessary fixing 152 as Illustrated in figure 2. A pole connector 560 is provided which is received Inside a hollow 156 of pole 150. The pole connector 560 has a bias member 562, extending from a pole receiving portion 564, that presses against an inner surface of the hollow 156 of the pole 150 to retain the pole connector 560 therein. The pole connector 560 also has an elongate arm 566 that extends down the side of pole 150 to provide a fixing 568 below the top of the pole 150. The elastic cord 550 is affixed to the fixing 5668 and the roof 500 is configured in a similar manner as shown in figure 2.

[0027] In use, the roof 500 can be applied to new and existing trampolines providing a coverthat protects the trampoline, and users of the trampoline, from the elements. To apply the roof 500 it is placed on top of poles 150 and the elastic cords 550 are tensioned between opposed poles 150 providing a substantially taught horizontal surface of elastic cords 550 extending radially from the central region 512. The shell 502 of the roof 500 is supported by the elastic cords 550, with regions of the shell 502 adjacent the elastic cords 550 forming apexes 510 and regions between adjacent pairs of elastic cords 550 forming troughs 520. The troughs 520 incline downwards from the central region 512 providing a channel which adapted to convey any water that lands on the roof 500 away from the central region to an outer periphery of the roof 500.

[0028] Advantageously the roof 500 provides a cover that protects the trampoline, and any users therein, from the elements, including rain. Any water, e.g. from rain, which lands on the roof 500 is conveyed down troughs 520 to an

2018264069 12 Nov 2018

-7 outer periphery of the roof 500 under gravity. This prevents the roof 500 from collecting or 'pooling' water which can otherwise lead to collapse of the roof.

[0029] The roof 500 is not only shaped to convey water away, but does so without the need for a rigid, or semi-rigid, support structure comprising aluminium or fibreglass struts, or the like. This not only reduces the chance of injury occurring between a user and the support structure, but also improves durability as there are no struts to break. Furthermore, it reduces the complexity of the roof, making it easier to install, and also significantly reduces costs in manufacturing and transporting the roofs.

[0030] The trampoline illustrated in figure 1 is for example only and is not to be regarded as limiting. The roof can be used with other trampoline designs, including trampolines wherein the poles either have spring members therein (e.g. a resiliently flexible portion) or mounted thereto (e.g. a leaf spring located on the pole above the mat) to support the mat via depending support members such as webbing.
