Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a gate indicator for a gateball game, which is attached so as to easily identify the number and position of the gate for a gateball game at the time of competition. (B) Conventional technology In addition to the fact that most of the gateball players are occupied by middle-aged people who have a weak visual acuity, the environmental conditions of the court where the gateball game is played are determined to be grounds, plazas, parks or open spaces. Notwithstanding this, it is not easy for a competitor to identify at a glance the order of the set gates of No. 1, 2, and 3 made of steel rods with a diameter of about 1 cm. Therefore, competitors demanded that the order of the gates be easily identifiable, and for that purpose, a cloth with a curtain hanging from the gate frame was temporarily proposed and used. Use is prohibited by the competition rules, and it is said that a number display device within 10 cm x 10 cm may be attached on the side frame of the gate.

In accordance with the rules of gateball competition, a display plate of a type that supports the gate number on the horizontal frame of the gate was inserted and supported, but it was put into practical use, but strong winds during competition, the coefficient of thermal expansion of the horizontal frame of the gate and the display plate Often, the display plate tilts or reverses and sags due to the loosening of the support portion due to the difference between the two and the impact when the ball hits the gate, which hinders the progress of the gate. C. Problems to be solved by the present invention The present invention solves the above-mentioned drawbacks such as the inclination and inversion droop of the display plate all at once, and the wind pressure, the difference in the thermal expansion coefficient between the gate horizontal frame and the display plate, and the impact. It is intended to obtain a gate indicator for a gateball game that can maintain the standing state on the horizontal frame of the gate. D. Means for Solving the Problems The present invention has been made in view of the above-mentioned points of view, and two hard plastic plates are provided, and the lower half predetermined portions on both sides of the plate are provided as bearing parts. As a scissors-like free-moving connection, and a spring member is interposed at a predetermined position in the upper half between the plate bodies so as to elastically urge the lower end opening of the plate bodies in a direction to always close the plate body. At the predetermined position in the back of the mouth, the mouth is always kept open at a constant level and the projecting sides having the function of positioning the gate are respectively provided in pairs, and the cross section of the mouth normally corresponds to the diameter of the gate horizontal frame. Form a gate holding surface that forms a part of the envelope surface of the circumference, attach a non-slip sheet such as rubber or soft plastic to the gate holding surface, and display the gate number on the outer surface of the plate. Tries to provide a gate indicator for gateball competition Than it is. E. Operation and Embodiment Hereinafter, one embodiment of the present invention will be described together with operation with reference to the drawings.

Two rigid plastic plate bodies 1 and 2 in which integral reinforcing bones are appropriately overhanged vertically and horizontally are provided on the back surface, and lower half predetermined portions on both sides of the plate bodies 1 and 2 serve as bearing portions, that is, one plate body. The shaft pieces 4 and 4 of the other plate body 2 are inserted into the holes 3 and 3 of the first body, and are integrally connected in a scissor-like manner so as to be freely movable. A spring member 5 having a required strength is interposed at a predetermined position between the plate bodies 1 and 2 so that the lower end opening portions 6 of the plate bodies 1 and 2 are always elastically biased in a direction to be closed. At the predetermined positions in the inner part of the mouths 6 of the plates 1 and 2, the mouths 6 are always maintained at a constant opening, and the projecting sides 7 and 7 having the function of positioning the gates are provided in pairs, respectively. In the normal state, the portion 6 is formed with gate holding surfaces 8 and 8 each of which forms a part of an envelope surface of a circumference whose cross section corresponds to the diameter of the gate lateral frame, and the gate holding surfaces 8 and 8 are made of rubber or soft material. Non-slip sheets 9 made of plastic or the like are attached. Opening angle limiting projections 10 and 10 for limiting the opening angle of the mouth 6 are provided at the upper edge portions of the plates 1 and 2, and knob protrusions and depressions are provided on the upper end portions of the surfaces of the plates 1 and 2. 11,
11 is attached. Gate numbers 12 and 12 are displayed on the surfaces of the plates 1 and 2 that are exposed to each other. The gate display device A for gateball competition is configured as described above.

Since the present invention has the above-mentioned configuration, the spring member 5 is repelled by holding the knob irregularities 11 and 11 on the upper end portion of the surface of the plates 1 and 2 that constitute the display A when the gate numbers are displayed. Opening angle limiting projections 10, 10 against the force
If the pressure is applied until the contact with the
Automatically opens. Gate 21 with its mouth 6 open
The horizontal frame 22 is inserted until it hits the projecting sides 7, 7, and when the clamping force by the hand is released there, the mouth portion 6 is naturally closed by the elastic force of the spring material 5, whereby the gate holding surfaces 8, 8 are formed. Can strongly eat the horizontal frame 22. Since the non-slip sheets 9, 9 made of rubber or soft plastic are attached to the gate holding surfaces 8, 8, the display tool A cooperates with the elastic force of the spring member 5 with respect to the gate lateral frame 22. Therefore, the standing posture in which the lateral gate frame 22 is embedded is stably maintained.

Effect of the Invention As is apparent from the above description, the present invention allows the display device displaying the gate number to be attached / detached to / from the gate horizontal frame by one-touch operation, and can be easily and reliably attached to the correct position without individual difference. Not only this, the standing state can be stably maintained on the gate horizontal frame due to wind pressure, a difference in coefficient of thermal expansion between the gate horizontal frame and the display board, and impact. Therefore, the one-touch operation directly and stably displays the gate number.
