Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tool for a high jump or a pole vault competition, and more particularly to a bar support that fixes a bar at a desired position and places a bar.
There are two types of equipment, one for facilities used only for athletes limited to formal stadiums, and one for schools and general stadiums used by many people for education and civil sports. Apart from this, the present invention has been invented so as to be suitable for both.
[0002]
[Prior art]
A typical conventional product of the above models is a pole with the height scale displayed on a pedestal, a bar mounted on a support slidably provided on this pole, and sliding the support up and down to raise and lower the height. The adjustment was performed, and the support was tightened and fixed with a handle screw at a desired position.
In this method, since the support is fixed to the pole at a point, a so-called "glare" has occurred.
Therefore, the present inventors devised Japanese Utility Model Publication No. 6-7725 in order to solve these problems. However, the problem cannot be completely prevented, and the so-called "grassiness" has occurred when the invented product has been used for a long time, albeit slightly.
[0003]
[Problems to be solved by the invention]
The present invention has been made by paying attention to the above points, and the present invention has been devised with a device for locking and fixing a bar mounting support slidably provided on a pole to solve the so-called "grassy" problem. Specifically, the principle of the universal hook is used for the locking and fixing means to obtain a more complete fixing state, and the operation can be performed by a simple operation. Things.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the bar support device for high jump competition according to the present invention has an end provided with a flat bar mounting table at the upper end of the main body as a support piece and the other end as a cover. A frame formed of two molds A and B;
A two-body fixing plate C and D having a pole insertion hole penetrating therethrough and a push button provided at an end thereof are opposed to each other, and a short strip is provided between the opposed two bodies near the front end of the fixing plate. The end portion is characterized by comprising a thin pipe penetrating through the two bodies, and a locking fixing member formed by interposing a spike between the pipes between the two bodies.
[0005]
Protrusions that fit into the grooves of the poles are provided on the side frame walls of the two mold bodies A and B that form the frame body, thereby preventing unnecessary rotation of the product of the present invention and the poles.
[0006]
[Operation]
The present invention provides a bar supporter for a high jump competition having the above-described configuration. Therefore, when the supporter is moved and fixed at a desired position, the two push buttons 11 exposed from the frame are provided. At the same time in the direction of the arrow in the drawing, the spring 40 interposed between the two bodies of the thin pipes 30 penetrating through the two fixed plates C and D is compressed, and the two fixed plates C and D are pressed. D becomes a parallel state, and the fixed state with the pole is released, so that it can move up and down. In other words, since the state in which the bar support is locked and fixed to the pole with the two universal hooks is released, the support can move up and down and can move to a desired position.
[0007]
On the other hand, when fixing the support at a desired position of the pole, if the push button being pressed is released at the desired position, C of the fixing plate is rebounded upward and D-body is simultaneously rebounded downward by the repulsive force of the spring 40, The distance between the ends of the fixing plate in the direction of the end is widened, and each of the poles assumes the state of a free hook on the pole, so that the fixing state is instantly firmly held and fixed. Therefore, in this fixed state, it is important that the interval between the two fixed plates C and D is wider in the sprung 40 interposed in the thin pipe than in the short sprout 20 at the tip.
[0008]
