Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a balance beam in which the beam itself has an explosive function.

BACKGROUND TECHNOLOGY In general, a balance beam is an exercise device equipped with legs that hold a single beam horizontally at a predetermined height, but since the beam is made of wood or a metal tube, it is rigid and does not bend by itself. Even if it does, it doesn't have the resiliency.

Problems that the invention aims to solve: According to the conventional balance beam, when performing a jumping movement on a beam, the practitioner must use his or her own jumping power, but the jump must be performed on a thin beam. As a result, jumping ability cannot be fully demonstrated.

On the other hand, there has been proposed a balance beam whose main body is divided into upper and lower halves, where cushioning materials are fixed at predetermined intervals along the entire length of the lower member, and where the upper member is placed above the cushioning material and covered with leather or the like. (Jikko 51-
10385, Utility Model Publication No. 52-4117). However, although this cushioning material has elasticity, since it is made of rubber, synthetic resin, or foamed polyethylene, its elasticity is weak, and therefore it is used to compensate for the lack of jumping ability of gymnasts or performers. It is not sufficient to assist in gymnastics or performance.

Means for Solving the Problems In view of the above-mentioned problems, the present invention provides a balance beam in which the beam itself has an elastic force, and extends over the entire length of the upper surface of the beam in one or more rows at predetermined intervals or closely spaced. A plurality of ammunition machines are fixed by using the same method, and a plate having a width and length that is approximately equal to the width and length of the beam is placed above the ammunition, and the beam and the plate surround the ammunition and are covered with a covering material. This is the structure of the balance beam.

Function According to the above configuration of the present invention, since the beam has the bullet, the stored force of the bullet compressed by the plate material through the covering material supplements the jumping power that the user lacks.

Embodiments The present invention will be explained below based on illustrated embodiments.

FIG. 1 is a front view, FIG. 2 is a sectional view taken along the line AA in FIG. 1, and FIG. 3 is a side view. In the figure, 1 is a beam, 2 is an extendable leg that supports beam 1, and 3 is a beam.
is a base for supporting and fixing the legs 2. As shown in FIG. 2, the beam 1 has a plurality of coil springs 4 arranged at predetermined intervals or closely spaced in one or more rows in the longitudinal direction on the upper surface of a square piece made of wood or metal. A plate material 5 having a width and length approximately equal to the width and length of the beam 1 is placed above these ammunition aircraft 4, and the beam 1 and the plate material 5 are wrapped around the ammunition aircraft 4 with a covering material 6. It will be covered. The side edge portion of the covering material 6 is fixed to the bottom surface of the beam 1 so that it cannot be easily removed. A cushion 7 such as a sponge is interposed between the plate material 5 and the covering material 6 to give a soft feel.

To explain the operation of the above embodiment, when a person using the balance beam steps on the covering material 6 on the plate material 5 and jumps, the bullet machine 4 is compressed and stored energy through the plate material 5, and the stored energy is Gives power to the user. Therefore, the user is able to perform desired techniques by supplementing his/her own lacking jumping power.

Effects of the invention According to the invention described above, a balance beam was created by compressing a coil spring, which has more elasticity than rubber, not as a cushioning material but as a bullet to compensate for the lack of jumping power. It becomes possible to perform or practice beyond the limit based on the person's lack of jumping ability.
