Description

  The present invention relates to a bar support used in a high jump competition in athletics, and provides a support that can easily move a bar support for fixing a bar in a desired position and has a strong fixation. It is.

  As shown in FIG. 5, a general high jump bar bar is constructed by detachably installing a lower tube 22 on a pedestal 77 and attaching a support member 55 of a bar 66 to the lower tube. 33 was inserted so as to be movable up and down, and the upper tube was fixed at a desired position with a fastener 44 such as a bolt.

Problems to be solved by the invention

Therefore, since the fixing method of the bar support in the conventional product described is based on points such as bolts, for example, if the athlete fails to jump and falls the support, the fixing may be released or loosened. Was often. In addition, in the case of use in a school where the position of the bar has to be adjusted up and down many times, complicated work such as loosening or tightening the bolt each time is required.
Therefore, the present invention is adopted as a method for fixing the bar support so that it can be easily performed, and the fixing method is changed from a point method to a method in which the fixing strength is improved, so that it can be performed firmly. To do.

Means for solving the problem

In order to achieve the above-mentioned object, the present invention is formed integrally with two members a and a ′, and has a hole 3 for inserting a column C in the central portion 1 and a bar mounted on one end. A bar support A that also serves as a cover body provided with a receiving portion 2 that exhibits a flat shape for use, and a grip hole 4 provided at the other end;
b and b 'are formed in two pieces, and a hole for inserting a support column C is formed in a substantially central part of the main body 11, and a ridge 14 is interposed between one end of the member. In addition to attaching the grip 12, the pin 13 having the ridge 15 interposed is composed of a slide fitting B provided between the two pieces,
The slide bracket B formed of two pieces b and b ′ is housed in a bar support A formed integrally by combining the two pieces a and a ′, and is attached to the column C so as to be movable up and down. As a means to solve the problem.

An embodiment of the present invention will be described based on an example with reference to the drawings.
The present invention is composed of two main members,
1 and 2 show a bar support A which is one of the members, and the support A also serves as a cover body of a slide fitting B which is another main member described later. And a ′ are integrally formed by combining two pieces of members, and a central portion 1 has a hole 3 for inserting a column C, and one end has a flat shape for placing a bar. A grip hole 4 described later is provided at the other end.

  FIG. 3 shows another member of the main member constituting the present invention, the slide fitting B, which is formed of two pieces of b and b ′, and also serves as a cover body. The bar support A described above is attached, and is provided on the column C so as to be movable up and down.

  The two pieces b and b 'forming the slide metal fitting B have the same shape, and a hole for inserting a column C is penetrated at a substantially central portion of the main body 11, and one end thereof is formed. The members b and b ′ are connected between the members with the ridges 14 interposed therebetween, and a grip 12 is provided at the other end portion exhibiting a remarkable rising shape from the main body 11. A pin 13 fitted with a ridge 15 is provided between the members b and b 'closer to the hole for inserting the column C.

FIG. 4 shows the present invention in which the bar support A described in FIGS. 1 and 2 is attached to the slide fitting B of FIG.
In the figure, the two pieces forming the bar support A are described with one piece a ′ removed.

  The slide fitting B is housed in the form of being housed inside the bar support A, and only the grip 12 of the fitting B is exposed from the hole 4 at the end of the bar support A.

  Since the slide fitting B accommodated in the bar support A is formed with the strips 14 and 15 interposed between the two pieces at both ends of the constituent members b and b ', it is always in the shape of a half-shaped katakana. And is fixed to the column C. That is, the two pieces of constituent members b and b 'are in a free-running state with respect to the column C, respectively, and the fixed state is extremely strong as compared with the conventional product.

  In the present invention, when the bar is fixed at a desired position, the two upper and lower grips 12 are brought in the direction indicated by the arrows in the figure, and the two pieces of components b and b ' The two pieces are in a two-letter parallel state of Katakana and the fixed state with the column C is released, so that the bar supporter can move up and down as indicated by the arrows in the figure.

In addition, the method of fixing the bar support that has been moved to a desired position is as follows.
The repulsive force of the ridge 15 interposed between the two pieces of the slide fitting B, b and b ′, instantly forms the Katakana half-shaped shape described above and is fixed to the column C.

The invention's effect

As described above, the present invention is composed of two main elements, the bar support A and the slide fitting B, and the bar support A is formed from two members a and a ′. The two pieces are united to form an integral body, and are provided with a bar receiving portion 2 at the end, a hole for a column C at the center, and a hole 4 for a grip at the other end.
The slide fitting B is formed of two members b and b ′, and the strips 14 and 15 are interposed near both ends between the two members, and a grip 12 is provided at one end, and the element And is provided on the column C so as to be movable up and down.

Therefore, according to the present invention, the two members b and b 'forming the slide metal fitting B are attached to the support column C in a katakana shape like a free rod, so that the fixation is strong and competitive. If the fixed position of the bar supporter moves due to the person's jumping failure, nothing will happen.
On the other hand, when changing the position of the bar, if the grip 12 is pinched and pushed from the top and bottom, the shape of the letter H changes, and the two members become parallel to the two-letter katakana shape, and the fixed state to the column is released. Since it can move up and down, it can be moved to a desired position.
When the bar support that has been moved to the desired position is released from the grip 12 that has been pushed from the top and bottom, the two pieces of the slide fitting instantly take on the shape of the former C and are fixed to the column C. In this way, the firmness of fixing, the ease of changing the position of the bar, the fixing after changing the position can be done instantly and firmly as before moving, etc. The effect is obtained.

It is a figure which shows the bar support of the main elements which comprise this invention. It is a side view of FIG. It is a figure which shows the slide metal fitting of the main elements which comprise this invention. It is a figure explaining the operation | movement of a vertical motion with a support | pillar in the state which accommodated the ride metal fitting in the bar support and removed the I piece among the bar supports. It is a figure explaining a typical conventional product.
