Problems solved by technology

[0002] Traditional trampolines that have been developed work in such a way that some coil springs are connected to an iron frame, so that the occupied area is relatively large
Moreover, the elasticity of the trampoline can only be controlled by installing and removing the coil springs
The trampoline is made of fabric so it is difficult to keep the user level and it is also difficult to install handles on it due to the nature of the trampoline so it does not provide any stability for the user
In addition, these springs also generate noise when they rub against each other

[0010] Best Mode for Carrying Out the Invention

[0011] According to the present invention, if figure 1 with 2 As shown, the elastically controllable trampoline that adopts leaf spring is formed in the following way, that is, the pedal 14 is connected to the upper end of the fixed plate 5 using a pedal connecting movable element 16 and connecting movable element 15, the pedal connecting movable element 16 and connecting movable element 15 The movable element 15 keeps the pedal 14 horizontal through the joint pin 4, so that the pedal 14 can move up and down. Thus, the pedal 14 can be operated with little force by means of the point of application adjusting screw 17 according to the principle of leverage. And leaf spring 11 adopts lever principle according to the motion of leaf spring supporting mobile frame 7. As a result, the twice-leverage principle is employed in the elastically controllable trampoline of the present invention. Thus, the trampoline of the present invent...

Abstract

Disclosed is an elasticity-controllable trampoline using a plate spring that can be manufactured in small size and in low height compared with existing trampolines using coil springs, thereby proving stability to a user. Also, it has a mechanical structure, thereby providing a semi-permanent life term. Under the principles of a lever using the third law of motion, particularly, the plate spring carries out action in smooth manner, in operation and also carries out reaction with the jumping operation of the user, such that the trampoline of the present invention will have a strong elasticity. In addition, a plate spring support movable stand on the plate spring is moved in simple manner according to the principles of the lever, thereby allowing the elasticity of the plate spring to be controlled. With the adjustment of the upward and downward motion of an action point operation bolt, the height of the upward and downward motion can be adjusted. Specifically, the step plate is maintained at a horizontal state, upon upward and downward motion, by the adoption of a coupling movable member for maintaining the step plate horizontally, and a bearing sheet is formed on the step plate with a result that the step plate can carry out a twist motion.

Description

technical field [0001] The invention relates to a trampoline with controllable elasticity using leaf springs. Background technique [0002] Traditional trampolines that have been developed work in such a way that some coil springs are connected on an iron frame, so that the occupied area is larger. Moreover, the elasticity of the trampoline can only be controlled by installing and dismounting the coil springs. The trampoline is made of fabric, so it is difficult to keep the user level, and it is also difficult to install handles on it due to the characteristics of the trampoline, so it does not provide any stability for the user. In addition, these springs also generate noise when they rub against each other. Because of these problems, there is a need for a novel trampoline of reduced size that provides stability and convenience to the user. Summary of the invention [0003] The object of the present invention is to provide an elastic controllable trampoline, which adop...
