Abstract: A trampoline support structure comprises a joining pipe including a longitudinal mounting hole and two transverse mounting portions, a first annular pipe including a first fitting segment and a first connecting segment, a second annular pipe including a second fitting segment and a second connecting segment, and a supporting pipe including a third fitting segment, in which the first annular pipe and the second annular pipe are mounted to the two transverse mounting portions of the joining pipe through the first fitting segment and the second fitting segment, respectively, while the supporting pipe is mounted to the longitudinal mounting hole of the joining pipe through the third fitting segment. In this case, the joining pipe is a linear tubular part so as to enable material cost savings with enhanced efficiency of assembly.

Abstract: A trampoline support frame comprises transversal and longitudinal branch pipes. The transversal ones are connected to form an annular frame. Each longitudinal one is provided with a fitting portion and two reinforcing portions integrally extended from the fitting portion to corresponding two side surfaces of the transversal one and then fixed to the transversal one by welding. The two reinforcing portions of each longitudinal one are extended from and integrally formed with the fitting portion, such that each transversal one is fixed to the two reinforcing portions by welding directly after the transversal one is placed between the two reinforcing portions without precision alignment, whereby the manufacturing process for the trampoline support frame is simplified, and manufacturing energy consumption is reduced to meet requirements for environment protection.

Abstract: A trampoline support structure includes a manifold, a first annular tube, a mesh encircled tube, a second annular tube and a support tube. The manifold includes a longitudinal installation portion, a transverse installation portion and an installation hole located on the transverse installation portion. The first annular tube includes a first assembly section inserted into the transverse installation portion and an anchor hole located on the first assembly section. The mesh encircled tube includes an anchor section inserted into the installation hole, the anchor hole and the longitudinal installation portion. The second annular tube includes a second assembly section inserted into the first assembly section. The anchor section, the longitudinal installation portion and the support tube form a multi-layer structure, thus can solve the problem of inadequate structural strength occurred to the conventional techniques.

Abstract: 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.

Abstract: A trampoline includes a frame, a protective circular net and a jumping portion. The frame has a circular base rack, a plurality of legs and circular net support racks respectively at two sides of the circular base rack. The jumping portion is located in the circular base rack and includes a flexible mat and a plurality of elastic support members having one end coupled on the flexible mat and another end fastened to the circular base rack. The protective circular net is hung on the circular net support racks. The protective circular net is held by a reinforced coupling portion which includes a holding section fastened to the flexible mat and a retaining section threaded through by at least one tightening member. The protective circular net has a lower edge with a plurality of apertures formed thereon threaded through by the tightening member to couple with the retaining section.

Abstract: A method of fabricating sleeves for trampolines includes steps of: first, bending a plate into a tube with a coupling seam bonded through a bonding process to form a sleeve; next, expanding an opening of the sleeve through an opening expansion means to form a body and an expanded opening section extended from the body; applying a compressive force to the expanded opening section to form an outer expanded portion and an inner folding portion. When the sleeve is coupled with a connection tube, the outer expanded portion and inner folding portion provide greater structural strength. Whether defects are formed on the coupling seam at the outer expanded portion and inner folding portion can be easily and visually detected after the fabrication process is finished. Thus defected sleeve can be instantly identified during the fabrication process to save extra inspection time. Fabrication productivity of trampolines also improves.

Abstract: A swing training apparatus includes an upright target portion and a ball capturing net. The target portion has a hit surface to be hit by golf balls. The hit surface has at least one ball inlet to receive the golf balls and a ball outlet at a lower section of the target portion. The ball capturing net is fastened to a side of the target portion to form a ball collection space therebetween. The ball collection space communicates with the ball inlet and ball outlet. The ball capturing net includes a ball guide slope leading to the ball outlet to direct the golf balls to leave the ball collection space through the ball outlet. Hence once the golf balls enter the ball inlet they can be retrieved easily for swing practice again without users going to the swing training apparatus to fetch the golf balls.

Abstract: A trampoline has an enclosure which includes a wire ring; a plurality of connectors connected to the wire ring; and a plurality of support poles. The support poles have a top end. The support poles have a top bend that bends inward at the top end. The wire ring is substantially inflexible during trampoline use. The trampoline also includes trampoline frame. The plurality of support poles are rigidly connected to the trampoline frame. A trampoline enclosure net is suspended from the wire ring at an upper portion of the trampoline enclosure net. A trampoline mat is included and the trampoline enclosure net is bounded by the trampoline mat at a lower portion of the trampoline enclosure net. A bounding surface is supported by a plurality of springs connecting between the bounding surface and the trampoline frame.
