Description

[Detailed description of the invention] Industrial application field The present invention relates to an auxiliary device for balance beams, and in particular, to give elasticity to the beam on the balance beam, and to utilize the elastic force during gymnastics practice. This allows for advanced practice.

BACKGROUND TECHNOLOGY In general, a balance beam is an exercise equipment 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, the balance beam is divided into upper and lower parts, and cushioning materials are fixed at predetermined intervals along the entire length of the lower member, and
An upper member is placed above the cushioning material and covered with leather etc. (Utility Model Publication No. 51-10385,
(Refer to Utility Model Publication No. 52-4117 and Utility Model Publication No. 53-6538).
However, although this cushioning material has elasticity, since it is made of rubber, synthetic resin, or foamed polyethylene, the elasticity is weak, and therefore it is used to compensate for the lack of jumping ability of gymnasts or performers. Otherwise, it is insufficient to assist in acting. Furthermore, when the main body of the balance beam is divided into upper and lower halves in this way, they are integrated and covered with a covering material to improve the appearance, but if the main body is finished covering the entire main body, the covering material may become dirty or damaged. In this case, the entire covering material must be replaced, which is a cumbersome task.

Means for Solving the Problems In view of the above problems, the present invention provides an auxiliary tool that is detachable from the beam and has elasticity.
This is designed to compensate for the lack of jumping ability of practitioners who perform jumping exercises on the beam. This auxiliary tool consists of a plurality of bullets interposed and fixed between two plates that are approximately equal to the upper surface of the beam, and can be removably attached to the beam using a hook. It was constructed by covering it with a covering material to improve the feel and appearance of the product.

Effects According to the above structure of the present invention, the auxiliary device that can be attached and removed from the beam has a bullet and is highly elastic, so when the practitioner steps deeply, the bullet is compressed and stores energy, and when the practitioner jumps, the bullet is compressed and stored. The stored elasticity can be given to the practitioner. Therefore, the practitioner can practice attempting a desired technique without worrying about his or her own lack of jumping ability. Furthermore, since the covering material can be attached to and removed from the beam using a hook, it can be easily removed and replaced.

Embodiment The present invention will be described below based on an illustrated embodiment. Figure 1 is the front view of the balance beam, Figure 2 is Figure 1A
-A sectional enlarged view, FIG. 3 is an enlarged sectional view similar to FIG. 2 showing another example, and FIG. 4 is a perspective view of the cushion material.

In the figure, 1 is a beam, 2 is a telescopic leg,
3 is a base, and 4 is an auxiliary tool. The auxiliary tool 4 covers the upper surface of the beam 1 over its entire length in the longitudinal direction, and is detachably fixed by a beam hook 5. As shown in FIG. 2, the auxiliary tool 4 includes a bullet 7 made of a plurality of coil springs fixedly interposed between two plates 6, such as plywood plates, each having a rectangular shape substantially equal to the upper surface of the beam, and a plate 6. , 6 and sandwiching the bullet 7, a cushion 10 is mounted on the upper surface of the upper plate 6 to cover the upper surface, and A covering material 9 made of special synthetic leather that covers the side surface of the beam 1 and hangs down approximately at the center of the side of the beam 1, and hook-shaped hooks connected to and facing the lower plate material 6 and provided at regular intervals in the longitudinal direction of the plate material 6. It consists of a plurality of beam hooks. The bombs 7 are arranged in one or more rows at regular intervals or closely in the longitudinal direction of the plate 6. The cushion 10 is made of sponge or the like and makes the covering material 9 soft to the touch. The cushioning material 8 may be a plate-shaped body with a quadrilateral cross section as shown in FIG. 2, but may also be a special cushioning material as shown in FIG. 4. This special cushioning material is formed by integrally molding a cylindrical rubber body 11 with inverted trapezoidal protrusions 12, 12 facing each other in the diametrical direction, and is often used in exercise equipment.

In the figure, the beam 1 is shown as a drum-shaped metal tube with an arcuate side protruding, but it is clear that it may also be made of a square piece of wood. Further, the beam hook 5 may be replaced with a string or a belt having a fastener. Furthermore, in the example shown in FIG. 3, the width of the plate 6a is wider than the beam 1, so it is used as a balance beam for practice by beginners.

To explain the operation of the above embodiment, the attachment and detachment of the auxiliary tool 4 is carried out by inserting one end of the beam 1 from one end side of the auxiliary tool 4 between the lower plate 6 and the pair of beam hooks 5, 5. It can be attached by pulling it toward the other end, and when it needs to be removed, it can be pulled out from either end of the beam 1. When the practitioner jumps on the auxiliary device 4, the bullet 7 is compressed and stores energy through the covering material 9 that has a good feel and the plate material 6 that has an appropriate hardness. Since it gives strength to the practitioner, it compensates for the jumping power that the practitioner lacks.

Effects of the invention According to the invention described above, the bullet interposed between two plates is compressed and stored through the covering material and the plate, and the stored force is given to the practitioner as an auxiliary aid. Since it is a tool, it is effective as a practice tool to compensate for a practitioner's lack of jumping ability and to master a desired technique.
Moreover, since the covering material can be attached to and removed from the main body using a hook, it can be easily replaced in the event of dirt, damage, or deterioration. It has the advantage of being lightweight since it does not impair functionality.
