Description

Shock absorbing member and jumping board with same

The present invention relates to a shock absorbing member and a jumping board having the same, and more particularly, to a shock absorbing member and a jumping board having the same, which can be manufactured inexpensively and simply while effectively reducing the noise generated during the shock absorbing action.

In general, jumping exercise is widely used regardless of age or sex due to various effects such as stimulating the growth plate to help the development of children or adolescents, or to reduce the body fat by shaking the belly fat. Such a jump exercise may be performed by simply rolling a foot with bare body, or may be performed in parallel with an arm exercise using a tool such as a skipping rope.

On the other hand, since the impact easily occurs in the process of rolling the floor with the foot or landing on the ground during the jump exercise, there was a fear that the crowd easily goes to the joint side such as the knee or ankle during the jump exercise. And such a jump exercise was not suitable for indoors because of the loud noise during exercise.

Therefore, in recent years, such as a jumping board has been introduced mechanisms that can effectively perform the jumping motion indoors without straining the joint.

Conventionally, such a jumping board has a footrest and a cushioning member provided to elastically support the bottom of the footrest. As the buffering member, a coil spring made of a metal material is usually used.

Therefore, in the case of performing a jumping exercise using a conventional jumping mat, since the impact applied to the footrest in the process of the player rolling the footrest or landing on the footrest is alleviated by the buffer member, it is possible to prevent the strain on the joint of the athlete. It will be possible to reduce the noise, so there is no big crowd to jump indoors.

However, even in the case of the conventional jumping board, in the case of the cushioning member provided with the coil spring, the contact noise between the spirals constituting the coil spring is caused during the expansion and contraction, thereby limiting the noise caused by the buffering action. As it was bent toward the side, it was not able to perform the buffering function properly.

On the other hand, noise generation and buckling phenomenon of the coil spring is not limited to the jumping board. Even when only the bed mattress is seen, the coil spring is often adopted inside, so that the contact noise occurs between the spirals of the coil spring or the coil spring is buckled to one side during the buffering action of the coil spring to provide cushioning force. That is, the noise-induced problem and the buckling phenomenon of the coil spring are common problems in all the various mechanical fields in which the coil spring is employed. In order to solve this problem, a metal coil coil surface is coated with a synthetic resin to reduce contact noise between the spiral portions of the coil spring, or insert a separate member to guide the expansion and contraction of the coil spring inside the coil spring. As can be seen, in this case, the price of the coil spring is greatly increased in the process of coating the coil spring, excessively deteriorating the manufacturability of the coil spring, or the expansion and contraction of the coil spring through the guide is limited to buffer the coil spring Another problem arises, such as a significant drop in performance.

In addition, since the conventional jumping board is provided so as to simply perform a jumping exercise, its use is limited only to the jumping exercise, and there are many difficulties in carrying out various exercises in various forms or using them for other purposes.
