Trampoline
A trampoline includes a rebounding portion and a circular support rack. The rebounding portion includes a pad and a plurality of elastic members located on the circumference of the pad. The circular support rack is located around the rebounding portion and connected to the elastic members, and includes an inner ring side facing the rebounding portion and an outer ring side opposite to the inner ring side, and also includes at least one first support tube and one second support tube. The first support tube and second support tube have respectively a bent tube section, a first coupling end and a second coupling end corresponding to the first coupling end. The first coupling end includes a first support section located on the inner ring side, a second support section located on the outer ring side and at least one first ridge between the first and second support sections.
1. A trampoline, comprising:
a rebounding portion including a pad and a plurality of elastic members on the circumference of the pad; and
a circular support rack which is connected to the elastic members to surround the rebounding portion and supported by a plurality of legs, and includes a vertical axis parallel to the legs and bisecting a profile of the circular support rack into an inner ring side facing the rebounding portion and an outer ring side opposite to the inner ring side, the circular support rack containing at least one first support tube and one second support tube, the first support tube including a first coupling end, a first jointing end and a first bent tube section between the first coupling end and the first jointing end, the second support tube including a second coupling end corresponding to the first jointing end, a second jointing end corresponding to the first coupling end and a second bent tube section between the second jointing end and the second coupling end, the first and second bent tube sections respectively including a first groove on the inner ring side and a second groove on the outer ring side to transfer stretching stress from the rebounding portion to the center of the first and second bent tube sections, the first coupling end and the second coupling end respectively including a first support section on the inner ring side, a second support section on the outer ring side, and at least one first ridge which is located on the vertical axis between the first support section and the second support section and formed by protruding towards a direction away from the legs to disperse stress from the plurality of elastic members to the first support section and the second support section equally.
2. The trampoline of claim 1 , wherein the first support section and the second support section are connected to the first ridge through at least one connecting section.
3. The trampoline of claim 1 , wherein the first jointing end and the second jointing end include a first auxiliary support section contacted with the first support section, a second auxiliary support section contacted with the second support section and a first auxiliary ridge contacted with the first ridge.
4. The trampoline of claim 1 , wherein the first support section includes a second ridge.
5. The trampoline of claim 1 , wherein the second support section includes a third ridge.
6. The trampoline of claim 1 , wherein the first coupling end and the second coupling end include a fourth ridge which is between the first and second support sections and extends towards the legs along the vertical axis.
7. The trampoline of claim 1 , wherein the pad includes a plurality of connection rings on the perimeter, each elastic member including a first end fastened to one connection ring and a second end fastened to the circular support rack.
8. The trampoline of claim 1 , wherein the first support tube further includes a branch tube.
