BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a closing member for closing an opening for leading out a communication cable or the like provided on a floor panel constituting a free access floor.

[0002]

2. Description of the Related Art Conventionally, there is known a free access floor in which a large number of floor panels are laid on a floorboard made of concrete and communication cables and telephone lines can be wired between them. In the free access floor configured in the above, an opening is provided at the edge of the floor panel at a required position in order to guide the communication cable and the telephone line to the floor, and the opening is closed by the closing member. There is. The closing member is formed in a rectangular shape according to the shape of the opening, and the closing member is provided with a sealing piece surrounded by a score line to form one or a plurality of conducting wire openings. This sealing piece is normally connected integrally with the closing member, and when opening the conducting wire opening, it can be cut at the position of the score line by pressing with a tool such as pliers. (Japanese Patent Application Laid-Open No. Hei 2
-8455).

[0003]

By the way, in the free access floor, the opening position of the lead wire opening is often changed by changing the installation position of the terminal equipment or telephone installed on the floor surface. According to the configuration, there is no means for storing the sealing piece that has been once separated from the closing member integrally with the closing member. Therefore, conventionally, a method such as sticking to the closing member using an adhesive tape or the like is used. According to this method, there is a fear that the blocking piece is often lost, and there is also a fear that the above-mentioned storage method by sticking is troublesome and scattered.

[0004]

Therefore, the present application solves the defects of the conventional one by opening and closing the conducting wire opening and by preventing the sealing piece from separating. That is, a plate body having a size for closing an opening provided in a floor panel and having one or a plurality of conducting wire openings, and a first supporting member supported at the position of the conducting wire opening to open the conducting wire opening. And a second position for sealing the lead wire opening, the lid piece being vertically rotatable, and the detachable lock for holding the closing piece between the lead wire opening and the sealing piece in the first position. Specifically, the plate body has a planar rectangular shape and extends forward from a rear edge thereof, and has a fitting concave portion and an engaging hole at front left and right positions thereof. And a sealing piece having a size for closing the conducting wire opening,
A shaft portion that rotatably fits in the fitting recess and an engagement piece that engages in the engagement hole are provided at the front left and right positions. Further, the locking means is provided between the pair of protrusions provided on the left and right side surfaces of the conductor opening or the sealing piece and displaced in the vertical and front-back directions, and between the pair of protrusions provided on the left and right side surfaces of the sealing piece or the conductor opening. It consists of an intervening nail piece.

[0005]

However, when not in use, the locking means
The sealing piece is held in the first position with the lead wire closed,
From this state, when opening the conducting wire opening for inserting and removing the communication cable or the telephone line, the rear end portion of the sealing piece is pressed downward. Then, the locking means is released and the sealing piece pivots vertically with the supporting portion as a fulcrum and hangs down, and the conducting wire opening is opened. Further, the sealing piece is rotated upward from this state, and the locking means again holds the sealing piece in the first position, whereby the conducting wire port is closed.

The left and right sleeve pieces 2 and 2 are made of a resin molded body integrally provided with a wall portion 3, and when the opening portion a provided in the floor panel B is closed by the closing member A, the opening portions are opened. Elastic locking pieces 2a that lock with the side edges of a are integrally provided.

The plate 1 is provided with two T-shaped conducting wire openings 5 extending forward from the rear edge and having fitting recesses 4 and 4 opening on the upper surface at the front left and right positions thereof. The bottom surface of the fitting concave portion 4 is formed in a U shape, and the engaging hole 6 is formed on the vertical side surface thereof, and the left and right side surfaces of the lead wire opening 5 are formed on the vertical side surface thereof.
A pair of projections 7 and 8 that slightly project and are displaced in the vertical and front-back directions are provided on the left and right sides of the lower surface of the plate 1, and downward projections 9 are provided.

A sealing piece 1 for planarly closing the conductor port 5.
Reference numeral 0 denotes a shaft portion 1 which is rotatably fitted in the fitting recesses 4 and 4 at the front left and right positions of a plate piece having the same shape as the conducting wire port 5.
The shaft portion 11 has a lower surface outer periphery formed in an arc shape so as to match the bottom surface of the fitting recessed portion 4, and the side end surface of the shaft portion 11 has the engagement portion. Engagement pieces 12 that engage with the holes 6 are provided, and horizontal claw pieces 13 that slightly project and intervene between the projections 7 and 8 are integrally provided on the left and right side surfaces.

The plate 1 and the two sealing pieces 10, 10 described above
As shown in FIG. 7, the sealing piece 1
In the state in which 0 and 10 are turned upside down, the tip slightly intervenes, and the plate 1 and the sealing pieces 10 and 10 are connected by the small piece 14 at the intervention position so as not to separate from each other, the synthetic resin Are integrally molded by. When the plate body 1 and the sealing pieces 10 and 10 thus produced are used, after separating the sealing pieces 10 and 10 at the small piece 14 position,
By reversing it, the shaft portion 11 is fitted into the fitting concave portion 4, the engaging piece 12 is engaged with the engaging hole 6, and the projections 7 and 8 are provided.
By interposing the claw piece 13 between them, the sealing piece 10 is held in the horizontal state and the conducting wire opening 5 is sealed.

The closing member A thus constructed has a floor panel B constituting a free access floor as in the conventional case.
Is placed on the upper surface of the flange b formed in a paragraph shape on the periphery so as to close the opening a formed in the plate, and the elastic locking piece 3 is locked to the side edge of the opening a and The protrusion 9 provided on the lower surface of 1 is attached by engaging with the engagement hole c provided in the flange b.

However, when the conductor port 5 is opened and the communication cable or the telephone line is led in and out with the closing member A attached to the floor panel B, the rear end of the sealing piece 10 is pressed downward. . Then, the claw piece 13 is disengaged from the lower protrusion 8 and the sealing piece 10 is rotated downward about the shaft portion 11 as a pivot as shown by the phantom line in FIG. Mouth 5 opens.

Further, in this state, when the conductor wire port 5 is to be sealed, the sealing piece 10 is rotated upward to interpose the claw piece 13 between the projections 7 and 8.

[00013]

As described above, according to the present invention, since the sealing piece is supported so as to be vertically rotatable with respect to the plate body, the conducting wire opening is opened and closed as desired by rotating the sealing piece. In addition, the sealing piece is not likely to be detached from the plate and lost, and the closed state of the conductor wire opening due to the sealing piece is held by the locking means so that the conductor wire opening is disturbed when not in use. In particular, according to the configuration of claim 2, there is an advantage that the synthetic resin molding is possible and the productivity is effective.
