DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap device for closing a hole formed in a floor panel or the like of a gymnasium when not in use.

[0002]

2. Description of the Related Art In a gymnasium, a hole is formed in a floor panel in order to insert and start a game pole such as volleyball. When the pole is not used, the upper opening of the hole is closed by a cap to prevent the competitor from stepping on the foot and tripping over. The conventional cap is fitted into the upper opening of the hole so as to be flush with the upper surface of the floor panel, and the cap is hinged at one end to the support wall at the upper part of the hole, and the other end of the cap is used. Is provided with a finger hook for raising and rotating the cap.

[0003] However, in the method of attaching by a hinge, in a use state in which the pole is inserted into the hole by raising the cap, the cap protrudes from the floor panel and remains on the floor, so that the cap is an obstacle. In addition, there is a considerable danger that the cap may be accidentally lifted by an impact given by the competitor in the closed state.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cap which can be properly restrained and held on the same plane as a panel when the hole is closed, and which is completely separated from the panel by a simple operation when the hole is used. It is to provide a cap device that can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a description will be given using reference numerals in the accompanying drawings. A panel hole cap device of the present invention is a fixed device fixed to a back surface of a cap 3 for closing a hole 2 of a panel 1. A case 4; a pair of left and right latches 5 and 5 which are housed in the fixed case 4 with the base end portions being entangled with each other and advance and retreat in opposite directions on the same straight line; The locking projection 5c is inserted between the receiving portion 5d and the tip spring receiving portion 5e of the other latch 5, and the locking projection 5c at the tip of each latch 5 is connected to the metal receiving portion 7 on the panel 1 side.
And a key handle 8 inserted into the fixed case 4 from the through hole 3a of the cap 3
Consists of The inclined drive surfaces 8b, 8b for pressing the inclined passive surface 5a at the base end of the latch 5 are formed on the left and right sides of the round bar-shaped tip key portion of the key handle 8 in the shape of a mountain with opposite inclinations, and the base end side of the inclined drive surface 8b. A pair of left and right locking grooves 8a, 8a parallel to each other are formed on the side surface of the key handle 8,
At the base end of each latch 5, a locking projection 5b is formed adjacent to the rear side of the inclined passive surface 5a, and the locking projection 5b of the latch 5 is engaged with the locking groove 8a of the key handle 8 so that the cap 5 3
From the hole 2.

In the cap device configured as described above,
When the hole 2 of the panel 1 is not used as shown in FIGS. 1 to 3, the cap 3 is fitted into the upper opening of the hole 2 and the locking projections 5 of the pair of left and right latches 5, 5 are provided.
The b and 5b are engaged with the metal receiving portions 7 and 7 on the panel 1 side to restrain and hold the cap 3 at a closed position on the same plane as the upper surface of the panel 1.

The tip key of the key handle 8 is attached to the cap 3
Of the key handle 8
When the inclined driving surface 8a of the base end portion of the latch 5 is pressed by the inclined driving surface 8b of the tip key portion, the pair of left and right latches 5, 5 are moved in the retreating direction against the bias of the spring 6, and the lock is locked. The stop projection 5c is detached from the receiving part 7. As a result, the cap 3 is unlocked from the panel 1.

When the key handle 8 is pushed further deeply, a pair of left and right locking grooves 8a, 8 on the side surface of the key handle are provided.
Since the locking projections 5b, 5b of the pair of left and right latches 5, 5 are engaged with the key a, the key handle 8 is connected to the cap device, and this connection state is accurately held by the biasing of the springs 6, 6. Then, when the key handle 8 is pulled up, the cap device is pulled out from the hole 2 with the cap device completely separated from the panel 1.

When the key handle 8 is rotated about the through hole 3a after the cap device is removed, the bottom surface of the locking groove 8a pushes the side surface of the locking projection 5b. At the stage when the key handle 8 has been moved forward by 90 degrees from the beginning, the engagement between the locking projection 5b and the locking groove 8a is released, as shown in FIG.
The side surface of “b” comes into contact with the arc side surface of the key handle 8. Therefore, the key handle 8 is pulled out of the cap device without being hindered by the locking projection 5b.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a handle portion of a key handle 8 made of a round bar is bent at a right angle to a main portion, and the entire shape of the key handle 8 is L-shaped. . A compression coil spring is used as the spring 6,
The latch 5 urged by the spring 6 to move is
c protrudes from the through holes 4 a in the left and right side walls of the fixed case 4. A through hole 4b for inserting the key handle 8 is provided at the center of the upper wall of the fixed case 4.

An inclined cam surface 5f is formed on the lower surface side of the locking projection 5c of the latch 5 so that the cap device can be connected to the hole 2a.
When the latch 5 is fitted into the bracket, the inclined cam surface 5f comes into contact with the tip of the metal receiving portion 7, whereby the latch 5 temporarily moves in the retreating direction.
When the cap 3 is inserted to the same position as the upper surface of the panel 1, the latch 5 returns to the forward position and the locking projection 5 c is
Engages.

[0012]

In the panel hole cap device of the present invention configured as described above, when the hole is closed, the cap 3 is engaged with the metal receiving portions 7, 7 on the panel 1 side by a pair of left and right latches 5, 5. 5, the cap 3 is accurately restrained and held by the panel 1, so that there is no danger of the cap 3 being accidentally lifted from the surface of the panel 1 due to an impact from an athlete or the like, and the cap 3 can be used stably.

Further, by engaging the locking projections 5b, 5b at the base ends of the pair of left and right latches 5, 5 with the pair of left and right locking grooves 8a, 8a on the side surface of the key handle 8, the entire cap device is formed. Is pulled out of the hole 2 and the cap 3 is completely separated from the panel 1 and can be removed.
Does not interfere with the competition.
