Description
TITLE: IMPROVED STRUCTURE OF TRAMPOLINE
(a) Technical Field of the Invention The present invention generally relates to a trampoline, and more particularly to an improved structure of a trampoline featuring omnidirectional-swing shock-absorption.
(b) Description of the Prior Art A conventional trampoline is generally composed of a circular or rectangular frame and a plurality of legs extending from a lower circumference of the frame to be positioned on the ground. A net, serving as a trampoline bed, is arranged at a center of the trampoline and has an outer circumference that is connected by a plurality of springs or elastic cables to an inner circumference of the frame. When a force is applied to the bed, the bed displaces downward in a normal direction thereof; when the force is removed, the springs or elastic cables provides the bed with a restoration force, causing the bed to return to the original home position. As such, a user can jump up and down on the bed to achieve an effect of sports exercise. However, the conventional trampoline is generally not provided a safety device on the circumferential edge thereof. If a user is not of skillful, or if an accident occurs, the user may get hurt. The use of the trampoline is definitely not safe.

2 A protection screen is thus available for use with a training trampoline to prevent a player from falling off the trampoline. However, the known protection screen is structured to mount, in a fixedly secured manner, to the trampoline and this results in a non-elastic mounting of the protection screen and may easy cause impact injuries or graze injuries of the player. Further, if the mounting is not made secure enough, the protection that the screen offers may be insufficient These are generally shortcomings of the conventional trampolines.
In view of the above problems, the present invention aims to provide a solution to overcome or at least alleviate the problems.
