DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for attaching a lid to a pole insertion hole of exercise equipment provided on a floor of a gymnasium or the like.

[0002]

2. Description of the Related Art In a gymnasium or the like designed for multipurpose use, a socket for inserting a pole used for various athletic sports such as volleyball, basketball, and handball is fixed below the floor surface, and is adapted to an athletic sport. The pole from the socket.

[0003] The pole insertion hole in the floor is closed by a lid when not in use, but when the lid is configured to be completely separated from the floor, the lid is likely to fall off when the lid is opened. There's a problem. On the other hand, when the lid is connected to the floor surface by a connecting means such as a chain, the operation is not smoothly performed because the chain is sandwiched between the lid and the edge of the pole insertion hole during the operation of fitting the lid. There is.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to prevent the lid from falling off and being lost during opening,
An object of the present invention is to provide a pole insertion hole lid attaching device for a gymnasium or the like in which a lid can be smoothly moved in and out of a pole insertion hole.

[0005]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. According to the lid mounting apparatus of the present invention, the lid is provided so as to face the socket 2 of the pole 15 of the exercise equipment fixed below the floor. An insertion hole 13 is provided in the floor 1, a pole insertion hole 3 a is provided in the fixed base plate 3 fitted and fixed in the lid insertion hole 13, and a notch 3 is formed in an edge of the pole insertion hole 3 a.
b, and a pair of first bearing plate portions 4
Is vertically provided, and the lid receiving plate 1 is fixed to the lower surface side of the lid 12.
A pair of second bearing plate portions 14 are provided at the center of the zero. The base ends of the pair of L-shaped first arm plates 7 are connected to the first bearing plate portion 4 of the fixed base plate 3 by a first horizontal pivot 5,
The base ends of the pair of L-shaped second arm plates 8 are connected to the first bearing plate portion 4 at positions displaced right beside the first arm plate 7 by the second pivot 6 in the horizontal direction. The distal end of the arm plate 7 was connected to the second bearing plate 14 of the lid receiving plate 10 by the third pivot 9 in the horizontal direction, and the distal end of the second arm plate 8 was shifted right beside the first arm plate 7. 4th Axis 1 in position
1 to the second bearing plate 14 and the first bearing plate 4
And the second bearing plate portion 14 and the first arm plate 7 and the second arm plate 8 form a parallelogram link.

In this lid mounting apparatus, when the socket 2 is not used, the lid 12 is fitted into the pole insertion hole 13 of the floor 1 as shown in FIGS. 1 and 3, and the upper surface of the lid 12 is flush with the floor. Is placed inside. When inserting the pole 15 into the socket 2 for a specific athletic competition, the lid 12
Is the pole insertion hole 1 by the operation tool using the vacuum suction disk.
Raised from 3. At this time, the first arm plate 7 rotates about the first pivot 5 with respect to the fixed base plate 3,
The second arm plate 8 rotates about the second pivot 6 with respect to the fixed base plate 3.

Along with the rotation of the first arm plate 7 and the second arm plate 8, the lid receiving plate 10 holds a posture parallel to the floor 1 due to the parallelogram link structure as shown in FIG. And at the final stage as shown in FIG.
The first arm plate 7 and the second arm plate 8 move to a position where they come into contact with the floor 1, and the lid 12 is held at a position as close as possible to the floor.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, the first arm plate 7 and the second arm plate 8 are connected to a base end portion 7a, in order to minimize the amount of lift of the lid 12 from the floor 1 in the open state. 8a is configured to be shorter than the distal end portions 7b, 8b. With such an arrangement, the movement trajectory of the lid 12 in and near the pole insertion hole 13 becomes substantially linear. The first bearing plate 4 is bent downwardly of the fixed base plate 3, and the second bearing plate 14 is
Is formed to be bent downward at the edge of the central opening 10a.

In order not to interfere with each other in the rotational movement of the first arm plate 7 and the second arm plate 8,
As shown in FIG. 6, the pair of first arm plates 7, 7 is arranged between the pair of second arm plates 8, 8, and the interval is secured by the spacer tube 16. In the closed state, the bent portions of the first arm plate 7 and the second arm plate 8 protrude toward the lower surface side of the floor 1, so that the socket 2 made of a metal pipe is arranged at a certain distance from the floor 1. Socket 2
Is fixed to the floor 1 and the underfloor foundation by a bracket metal separately.

[0010]

As described above, in the lid attaching device of the present invention, the lid 12 is connected to the floor 1 via the first arm plate 7, the second arm plate 8, and the fixed base plate 3, so that the socket 2 The location of the lid 12 is clear even when the pole 15 of the exercise equipment is inserted into the
There is no danger of falling off.

The base end of the L-shaped first arm plate 7 is connected to the first bearing plate portion 4 of the fixed base plate 3 by the first pivot 5, and the base of the L-shaped second arm plate 8 is connected. End the second pivot 6
The first arm plate 7 is connected to the first bearing plate 4 at a position shifted right beside the first arm plate 7, and the distal end of the first arm plate 7 is connected to the second bearing plate 14 of the lid receiving plate 10 by the third pivot 9. And the second arm plate 8 is connected to the second bearing plate portion 14 by the fourth pivot 11 at a position where the distal end of the second arm plate 8 is shifted to the side of the first arm plate 7, and the first bearing plate portion 4 and the second Double bearing plate 14
In addition, since the parallelogram link is formed by the first arm plate 7 and the second arm plate 8, the lid 12 always rotates while keeping parallel to the floor surface, and is substantially in the lid insertion hole 13 and in the vicinity thereof. Since the linear motion trajectory is drawn, it does not catch on the edge of the lid insertion hole 13. Thereby, the play gap between the outer peripheral surface of the lid 12 and the inner peripheral surface of the lid insertion hole 13 can be reduced to the utmost, and the unevenness of the floor surface at the time of loading the lid can be reduced as much as possible, and one-sidedness can be sufficiently secured. Can be.

In the lid removal position, the lid 12 occupies a position as close as possible to the floor surface, so that it does not become an obstacle. Furthermore, the first bearing plate 4 and the second bearing plate 1
4 and the first arm plate 7 and the second arm plate 8 are arranged as a pair, so that the lid 12 is stably held without tilting, and the fitting operation into the lid insertion hole 13 is performed more smoothly. .
