Technical Field

[0001] The invention relates to a trampoline support folding structure and a trampoline, belonging to the field of sports goods. Background Art

[0002] A trampoline is a common recreational and sports equipment, mainly composed of a trampoline surface frame, supporting leg frames, jumping cloth, springs, etc. Since general trampolines are large and bulky, when not in use, they not only occupy a certain space, but also take up a lot of time and manpower to move.

[0003] Although the existing trampoline can be disassembled and stored, its parts are scattered after disassembly, which is inconvenient to carry and easy to lose parts. Therefore, there is an urgent need for a trampoline that can solve the problem that the existing trampoline cannot be folded and disassembled, resulting in occupying a large space and being inconvenient to carry.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1-2 As shown, the folding structure of the trampoline support comprises a plurality of telescopic columns 1 and a folding mechanism disposed between adjacent telescopic columns 1, the telescopic columns 1 and the folding mechanism surround to form a regular polygon, and the telescopic columns 1 are provided with a locking mechanism 2;

[0025] The folding mechanism includes a first connecting member 3 arranged on the upper edge of the side wall of the telescopic column 1, a second connecting member 4 arranged on the lower edge of the side wall of the telescopic column 1, a folding rod 5 that connects adjacent telescopic columns 1 through the first connecting member 3 with rivets and can rotate axially along the connection, an X-shaped frame 6 that connects adjacent telescopic columns 1 through the first connecting member 3 and the second connecting member 4 with rivets and can rotate axially along the connection, and the intersection of the two rods of the X-shaped frame 6 is connected by rivets, and the two rods can rotate axially along the rivet.

[0026] In the stowed state, the telescopic column 1 is in a stretched state. When unfolded, the telescopic column 1 contracts, driving the folding rod 5 to unfold and the horizontal angle of the X-shaped frame 6 to decrease during the contraction process. After fully unfolded, the locking mechanism 2 locks the telescopic state of the telescopic column 1, and the folding rod 5 and the X-shaped frame 6 form a support.

[0027] In another embodiment of the present invention, Figure 3 As shown, the folding rod 5 includes two support rods of equal length, each of which has a slot below one side of the two support rods, in which a third connecting member 7 is arranged, and rivets connected to the support rods are arranged on both side walls of the third connecting member 7, and the support rods can rotate along the axis of the rivet.

[0028] The slot of the support rod is arranged below it, which provides a limit for the axial movement of the support rod on the one hand, and on the other hand, the third connecting member 7 is embedded, and the ends of the two support rods are abutted, thereby forming a relatively stable support that is not easy to deform.

[0029] In another embodiment of the present invention, a tow bar 8 is further included. One of the multiple telescopic columns 1 extends upward to form a sleeve 9. The tow bar 8 is arranged in the sleeve 9, and the position of the tow bar 8 is adjusted by a hand-tightened bolt (a bolt with a hexagonal or plum blossom cap on the head, and the user can grasp the head to adjust the tightness without the aid of tools) passing through the side wall of the sleeve 9.

[0030] The towing bar 8 is provided for easy carrying and can be used as a supporting structure in the unfolded state, so that the user can hold the towing bar 8 to keep the body balance when jumping on the trampoline.

[0031] In another embodiment of the present invention, the locking mechanism 2 is a hand-tightened bolt, or other conveniently adjustable fixing methods.

[0032] The locking method is described by taking a hand-tightened bolt as an example: after the telescopic column 1 is retracted, it is in a state where support rods of different diameters are sleeved. After the hand-tightened bolt passes through each support rod in turn, the telescopic state can be limited to achieve locking.

[0033] In another embodiment of the present invention, the bottom of the telescopic column 1 has an anti-skid pad to increase its friction and prevent displacement.

[0034] Example 2

[0035] A trampoline comprises a trampoline support and a trampoline cloth, wherein the trampoline cloth is arranged on the upper end surface of the trampoline support and is fixedly connected, and the trampoline support has the trampoline support folding structure in embodiment 1.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
