Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to horizontal bar exercise equipment for gymnastics.

[Background of the idea]

In general, it is not preferable to rigidly connect both ends of the iron bar for this type of gymnastics to the support body. In other words, in order to make a person swing his or her body back and forth, or rotate the body around a horizontal bar like a large wheel, this kind of movement cannot be achieved unless the horizontal bar rebounds, that is, the horizontal bar bends.

[Conventional technology]

It is already generally known that the horizontal bars used by gymnasts and others to perform advanced techniques are equipped with a mechanism that causes rebound, and that the athletes themselves adjust the bars to obtain the rebound that suits them.

However, very common height-adjustable iron bars do not have a structure that allows such rebound (bending) to occur.
Therefore, even simple horizontal bar exercises such as kicking up are difficult, and the current situation is that only exercises that are not suitable for horizontal bar exercises are provided.

[Purpose of invention]

The present invention was developed in view of these circumstances, and aims to solve the problems of the conventional technology by simple and rational means, provide the general public with a horizontal bar with rebound, and improve the technique of horizontal bar gymnastics. It is something that I will try to plan.

[Means to resolve the problem]

In order to solve the conventional problems, the horizontal bar exercise equipment of the present invention has connecting bodies having a U-shaped planar shape attached to both ends of the horizontal bar so that the openings face outward, and these connecting bodies are erected. In the iron bar exercise equipment, which is fitted onto each of the square pillars, and in which a tightening bolt is inserted through two opposing sides of the connecting body and the square pillar to connect the two, one side of the connecting body is fitted with the aforementioned tightening bolt. The bolt is loosely supported in a ring-shaped groove formed in a nut member that is screwed onto the bolt, and the width of the groove is made larger than the thickness of the connecting body to form a gap 10 between the two for the rebound of the iron bar. , is characterized in that a rebound gap 12 is also formed between the side of the connecting body to which the iron rod is attached and the square column.

〔Example〕 The details of the embodiments will be explained with reference to the drawings.

Fig. 1 shows a movable iron bar exercise device, in which 1 is a stand member, 2 is a square pillar erected on the stand member 1, and holes 3 for height adjustment are provided in the square pillar 2 at appropriate intervals. There is. 4 is an iron bar.

Next, the main structure of the present invention will be explained with reference to FIG. 2. Connecting bodies 5 having a U-shaped planar shape are attached to both ends of the iron rod 4 so that the openings face outward.
The connecting bodies 5 are respectively fitted into the square pillars 2 which are erected to face each other. Two opposing sides 5 of the connecting body 5
A and 5b have holes 6 that fit the holes 3 of the square column 2.
A tightening bolt 7 having a tightening head 7a at one end is inserted into both holes 3 and 6, so that a connecting body 5, that is, an iron bar 4 is attached to the square column 2. There is. One side 5b of the connecting body 5
is loosely fitted into a ring-shaped groove 9 provided in a nut member 8 that is screwed onto the tightening bolt 7, and the width of this groove 9 is wider than the wall thickness of the side 5b. A rebound gap 10 is formed between the groove 9 and the groove 9. In addition, a boss portion 5c centered around the hole 6 is provided on the inner surface of the other side 5a,
The resistance of the side 5b to the nut part 8 and the pressing resistance of the side 5a to the boss part 5c and the two faces of the prism are balanced.

Further, a rebound gap 12 is formed between the inner surface of the side 5d of the connecting body 5 having the support tube 11 for connecting the iron rod 4 and the square column 2. This gap 12 can also be used as a play that allows the iron rod 4 to tilt relative to the square column 2 when adjusting the height of the iron rod 4. In the figure, reference numeral 13 denotes a knock pin for connecting the iron rod 4 and the support tube 11.

〔effect〕

As described above, according to the present invention, the following effects can be obtained.

(a) The vertical rebound of the iron bar can be achieved by the presence of the gap 12, and in addition, the rebound effect is increased by the loose fit between the sides of the connecting body and the nut member.

(b) Rebound in the longitudinal direction of the horizontal bar is obtained by the presence of the gap 10, and in combination with the rebound effect due to the gap 12, advanced techniques of horizontal bar gymnastics can be performed.
