Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of balance beam exercise equipment for kindergartens and lower grade children.

[Conventional technology] Conventionally, balance beam exercise equipment for kindergartens and lower grade children has been floor-standing, or has a beam with a semicircular cross section installed between jumping boxes like a bridge, and the arc or plane of this beam is Using this technique, children were asked to perform average exercises to develop their balance and motor skills.

Conventionally, balance beams of this type have mainly been very monotonous, as mentioned above, and as children's motor skills develop, this type of balance beam has become unsatisfactory. On the other hand, if it is custom-made for a product with a different surface shape, i.e., a surface with an irregular shape that makes it difficult to average motion, the cost will increase, and having several types of products is difficult to carry out from the hangar, carry it in, etc. There is a problem with the handling.

The purpose of this invention is to enable multiple types of balance beam exercises to be performed using one exercise device, and by simply reversing it on the spot, it is possible to provide a balance beam that suits the aptitude of young children, which is also economically advantageous. The purpose is to provide a balance beam exercise equipment that is suitable for use in sports.

[Means for Solving the Problems] The structure of the present invention which solves the problems of the prior art consists of a plurality of long rods of equal length and different surface shapes, and a combined body, and each of the long rods The balance beam main body A is attached to the outer periphery of the above-mentioned combination body so that the longitudinal axes thereof are parallel to each other, and each of the above-mentioned long rods is arranged in a substantially equally distributed manner. It is characterized by comprising a plurality of pedestals having engaging recesses that fit into the parts.

[Example] Next, details of an example of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view, FIG. 2 is a side view of the balance beam supported on a pedestal, and FIG. 3 is a side view of the balance beam placed directly on the floor.

As is clear from FIG. 1, numeral 1 is a composite body made of wood etc. arranged at equal intervals, and has a substantially triangular shape as shown in FIGS. 2 and 3. The two adjacent apex corners of are cut off as shown in the figure to form mounting surfaces 1a and 1b for long rods 2 and 3 made of wood, which will serve as balance beams, and the remaining apex corner is cut off as shown in the figure. is integrally provided with a rectangular extension extending outward, and an attachment surface 1c for attaching another elongated rod 4 is formed at the end of this.

As shown in FIGS. 2 and 3, the long rods 2, 3, and 4 attached to each of the mounting surfaces 1a, 1b, and 1c are
They are fixed to the combined body 1 with L-shaped fittings 5 and screws 6, respectively.

The long rod 4 attached to the mounting surface 1c is
As described above, since it is attached to the extension part connected to the apex corner of the combined body 1, the apex protrudes outward compared to the mounting surfaces 1a and 1b from which the other apex corners have been cut. For this reason, since the outer surface of each long rod 2, 3, 4 is located at the top of an equilateral triangle, the long rod 4 is formed relatively thinner than the other long rods 2, 3, and The cross-sectional shape is semicylindrical, and the curved surface 4a is attached facing outward.

The long rod 2 attached to the mounting surface 1a of the above-mentioned combined body 1 has a circular arc surface 2a with a round cross section and a flat surface 2b.
The long rod 3 attached to the mounting surface 1b has a plane 3a that is on the same plane as the plane 2b of the long rod 2, and a plane 3b parallel to the mounting surface 1b.
, an arcuate surface 3c connecting both planes 3a and 3b, and an arcuate surface 3d inclined toward the elongated rod 4 side.

7 is a flat plate 8, 9 bridged between the combined body 1 by using the gap between the long rods 2 and 3;
The road surface 8a, 9b is bridged between the combined body 1 by utilizing the gap between the long rod 4 having a semi-cylindrical cross section and the other two long rods 2, 3 adjacent thereto. It is a rod, and the balance beam main body A is constituted by the above structure.

Reference numeral 10 denotes a pedestal for supporting the balance beam main body A on the floor surface, and this pedestal 10 is formed with an engagement recess 10a in which each of the long rods 2, 3, and 4 is fitted into the deepest part. has been done. As is clear from FIG. 2, this pedestal 10 is used when the flat plate 7 is used directly above or when the rods 8 and 9 are used directly above. In addition, when using each side of the long rods 2, 3, and 4 directly above, the balance beam main body A is placed directly on the floor as shown in the figure, without using the pedestal 10 as shown in Figure 3. Place it on. Third
The figure shows the state in which the long rod 4 and the treads 8a and 9a of the rods 8 and 9 are used.
Of course, each of the long rods 2 and 3 can be used independently by rotating them.

In the above embodiment, three long rods 2, 3, 4, a flat plate 7, and rod rods 8, 9 are combined, and these are connected parallel to the combined body 1 whose front shape is approximately triangular. Although the balance beam main body A is shown as being radially attached, it can also be constructed using an odd number of long rods such as 5 or 7 rods, so the construction is not limited to that of the embodiment. The reason for using an odd number of long rods is that when placed directly on the floor, each long rod becomes the top and can be used as a single balance beam, but an even number of long rods is used. However, if effective balance beam movement can be achieved depending on the arrangement, the number of long rods to be used is determined based on the overall weight and is not specified.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) One balance beam main body structure allows young children to exercise on a balance beam with each long rod as the apex, and in particular, in the present invention, each long rod has a different surface shape, so it is not used. The long rod allows balance beam exercises of varying degrees of difficulty to be performed depending on the child's aptitude.

(b) In addition, long rods with different surfaces can be used by simply rotating the balance beam main body at the site, eliminating the conventional hassle of transporting different balance beams to and from the site. Therefore, it is possible to appropriately teach balance beam exercise using time effectively.

(c) By inserting and fitting each of the long rods that make up the balance beam body into the deepest part of the engagement recess of the cradle, the height of the other long rods located on the top surface can be increased and further increased. Not only can the level of difficulty be improved, but children can also be given a variety of exercises, such as balance beam exercises that utilize the empty spaces between the long rods.
