DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid which is detachably attached to a wiring outlet formed on a floor panel of a free access floor.

[0002]

2. Description of the Related Art Conventionally, a large number of floor panels are laid on a base floor such as a concrete floor and a space is formed between the floor panel and the base floor for a cable wiring or the like. A double floor structure called an access floor is known.

In the free access floor, power cables and signal cables for computer terminal equipment and communication equipment can be freely wired in the space below the floor. In order to connect the terminal device and the communication device arranged on the upper surface side of the floor, it is necessary to take out the wiring under the floor to the upper surface side of the floor. A wiring outlet is formed.

[0004] In a conventional floor panel, a form of a wiring outlet is formed by forming a cutout recessed inside the panel in a substantially semicircular or semielliptical shape or a rectangular shape on the outer periphery of the floor panel. There have been proposed several structures in which a cover capable of forming a communication hole later is placed and mounted in the cutout portion, and some of the same types are already in practical use.

[0005] As an example of a conventional product, as shown in FIG. 10, a synthetic resin lid C attached to a notch K formed by recessing the inside of the panel P on the outer peripheral edge of the panel P,
In order to form the wire hole H later, a thin groove-shaped cut S along the shape of the wire hole H is formed in the cover C, and the minute connecting portion L is left on the cut S when the cover C is formed. Formed,
When passing the wire, the cap-shaped small piece Pi surrounded by the cut S is removed to form a wire opening H.

However, with the above-described form and structure of the communication port H, the opening area of the communication port H cannot be so large, so that the amount of cable that can be pulled out from one communication port H is limited. There was a limit and there was some difficulty in usability. In particular, when the cutouts K, K of the adjacent panels P are arranged opposite to each other, a considerable amount of cables can be drawn out by separating the cables from the four wire openings H of the two lids 1. Must be done, which not only complicates the process,
The appearance was not good either.

Further, a cover C mounted on a mounting flange (not shown in FIG. 10) of a cutout K which is opened in a substantially semicircular shape on the outer periphery of the floor panel P is also wired to the communication hole H. When a cable or the like is inserted, or when the cable is pulled from above after the insertion, there is a problem that the cable is easily caught on the flange. In order to avoid this, in the conventional product, it is indispensable to take measures such as attaching a radius to the edge of the mounting flange.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems of the wiring outlet of the conventional free access floor panel and the lid thereof, and has been developed in consideration of the above problem. When arranged facing each other, the through-holes of the facing panel are connected and integrated so that they can cope with the insertion of a large amount of cables, and when the cables are pulled out, the cables catch on the flanges formed in the cutouts of the panel. It is an object of the present invention to provide a lid for a wiring outlet of a floor panel which is free from a fear.

[0009]

FIG. 1 shows a cutout portion for taking out, which is provided with a cutout groove 2 and a cap 3 which are substantially U-shaped in plan view for forming a communication hole H to be described later.
An example of the lid 1 of the present invention shown in FIG. 2 is removably mounted.
Hereinafter, this point will be described.

First, the notch 20 in the panel P shown in FIG.
Are formed in a flange shape. The support side 21 has a cover 1 described later on its left and right sides.
Locking notches 21a and 21b are formed for fitting and guiding the locking claw pieces 9 and for holding the lid 1 in the cutouts 20.

The lid 1 of the present invention, which is mounted in the cutout portion 20 for taking out the wiring of the panel P, has a flat shape that fits within the outer contour of the cutout portion 20, and has the panel P on its outer periphery.
A cap 3 is provided, facing the side 1a along the outer periphery of the cap 3 and surrounded by a groove-shaped notch 2 which is substantially U-shaped when viewed from a plane. The cap 3 is held on the lid 1 by a thin holding portion 2a left in the groove-shaped notch 2. When the holding portion 2a is cut, the cap 3 comes off the lid 1 and thereby has a substantially U-shaped flat surface. A wire opening H is formed. The holding portion 2a is not limited to the strip-shaped holding portion, but may be a half-punched holding portion in which a thin bottom is left in the groove-shaped notch 2, or may be a combination of these. Good. In addition, the groove-shaped notch 2 forming the communication hole H can have any planar shape such as a semicircular shape, a triangular shape, and a rectangular shape in addition to the U-shape.
Further, the size and position of the notch 2 are not limited to the embodiment.

Reference numeral 4 denotes a rib-shaped standing wall having a substantially U-shape on the back surface of the lid 1 so as to surround the groove-shaped notch 2.
5 is a vertical wall 4 near the outer side 1a located at the front end of the lid 1.
A standing wall 6 integrally formed with the front wall, 6 is a reinforcing standing wall formed continuously with the two standing walls 4 and 5 and formed substantially at the center of the lid 1, and each of the standing walls 4 to 6 is a lid 1 To support the vertical load applied to the cover 1 without warping the lid 1.

Reference numeral 7 denotes a through-hole recess formed between the left and right groove-shaped notches 2 holding the caps 3 formed on the left and right sides on the outer side 1a of the lid 1, and 8 denotes a cap for the cap 3. It is a rib-shaped support piece which is vertically formed at substantially the center of the rear surface along the length direction of the cap 3 at the same height as the standing walls 4 to 6. The planar shape of the concave portion 7 can also be an arbitrary planar shape such as a semicircle or a V-shape. In addition, the number of formed portions can be arbitrarily selected according to the length of the extra length of the outer side 1a of the lid 1.

In the lid 1, reference numeral 9 denotes a locking claw piece for attaching and detaching the lid, which is formed on the left and right sides of the rear surface of the lid 1 so as to form a substantially elongated U-shape as viewed from the front, which is erected downward. It is resiliently locked at a step 9a formed by projecting outward from the claw piece 9 in the locking notch 21a, 21b of the panel P. Reference numeral 10 denotes an operation hole having a substantially semicircular planar shape for operating the locking claw piece 9 by grasping it with a finger from the upper surface side of the lid 1.

As described above, an example of the lid 1 of the present invention is formed. The planar shape of the lid 1 is a semi-elliptical shape in the example shown in FIGS. 1 to 4, but the present invention is not limited to the illustrated example,
For example, lids of other planar shapes such as semicircle, triangle, etc.
It can be applied as it is. Of course, the planar shape of the lid 1 corresponds to the planar shape of the notch 20 on the panel P side, so that the planar shape of the notch 20 and the lid 1 may correspond to any planar shape. It must be of a shape with. The material of the lid 1 is desirably made of synthetic resin in terms of molding and the like. However, the lid 1 of the present invention is not limited to synthetic resin, and may be made of metal, for example.

The lid 1 of the present invention shown in FIGS. 1 and 2 is provided with a notch 20 as a wiring outlet of the floor panel P of FIG.
It is mounted and used as shown in FIG. When the lid 1 is attached to the notch 20, the right and left locking claw pieces 9, 9 formed on the back surface of the lid 1 are fitted and guided by the locking notches 21 a, 21 b of the notch 20. 1 is easy to install, and
After the attachment, the steps 9a, 9a of the locking claw pieces 9, 9 are
Since it is locked to a and 21b, there is no danger of it coming off due to vibration or the like. In this mounting mode, when it is desired to form a wire opening H in the lid 1, the cap 3 is separated from the lid 1 by hitting or cutting the holding portion 2 a of the groove-shaped notch 2. , A communication hole H is formed.

The cover 1 for a wiring outlet according to the present invention is
In this embodiment, the cap 3 having a substantially U-shaped plane is supported by the groove-shaped notch 2 via the holding portion 2a, that is, the cap 3 is provided in the notch 20 of the panel P. Because it is not supported by the flange-like support side 21,
Before separating the cap 3 from the lid 1, the cap 3
When a concentrated load is applied to, the holding portion 2a cannot withstand the load,
There is a possibility that it will be cut.

In order to cope with this point, in the present invention, a rib-shaped support piece 8 for preventing bending is formed on the back surface of the cap 3. For example, as illustrated in FIG. 5, even when a concentrated load such that the heel h of the high heel is placed on the cap 3 is applied, the lower portion of the side end 8 a of the support piece 8 hits the rib-shaped standing wall 4. Because it is supported, even if a part of the holding portion 2a of the groove-shaped notch 2 is about to be cut, it does not break even if the cap 3 receives such a concentrated load.
There is no risk of coming off the groove-shaped notch 2.

In the present invention, since the cap 3 is provided so as to face the outer side 1a of the lid 1 (the side on the same side as the outer periphery of the panel P), the adjacent panels P are When the lids 1 and 1 face each other as illustrated in FIG.
The caps 3, 3 are located opposite to each other, whereby two opposed U-shaped grooved notches 2, 2 are formed.
Will form one oval notch. Of course,
When the groove-shaped notch 2 is semicircular or triangular, it becomes a circular or square notch.

As a result, when the opposing caps 3 and 3 are removed from the opposing lids 1 and 1, a single oval wiring opening H 'for taking out the wiring is formed. , 1 allows a large amount of wiring to be drawn out from one take-out port, which not only allows the wiring work to be performed rationally, but also improves the appearance of the drawn-out wiring.

Moreover, since the wiring hole H for taking out the wiring formed by removing the cap 3 is surrounded by the rib-shaped standing wall 4 having a flat U-shape, the installation form of the standing wall 4 is drawn out. This serves as a guide for the wiring to be performed, and the situation in which the wiring to be drawn is hooked on the flange of the cutout portion of the panel P unlike the conventional product does not occur. In order for the standing wall 4 to more effectively fulfill the role of a line guide, a rounded end can be provided at the lower end 4a of the standing wall 4. The standing wall 4 is provided with wiring extending to the upper surface side of the panel P.
Since the component members, specifically, do not directly contact the metal flange-shaped support side 21, the coating of the wiring is not damaged at the time of extraction by the burrs remaining on the support side 21, and is not broken, Electrically safe. In this regard, it is particularly useful when drawing out wiring with a broken coating.

Further, according to the present invention, on the side of the outer side 1a of the lid 1,
With the provision of the recess 7 for wiring, in the case of a small amount of wiring or a thin cable, it is possible to draw out the wiring from the recess 7 without removing the cap 3. When the recesses 7 are arranged such that the adjacent lids 1 face each other, the recesses 7 of the two lids 1 are integrally formed in one hole, so that a larger amount of wiring is required. There is an advantage that it can be taken out, and furthermore, it is preferable from the viewpoint of safety that the drawn out wiring does not have to come into contact with the edge of the panel constituent member (mainly made of metal).

In the present invention, instead of the rib 8 for preventing the cap 3 from being bent before the removal as described above, or in addition to the rib 8, it is possible to prevent the cap 3 from being bent as shown in FIG. The piece 8 ′ may be vertically provided on the front end face side of the cap 3. In this case, a receiving protrusion 5a or 4b may be provided on the front end face of the standing wall 5 or the standing wall 4. The bend preventing piece 8 ′ can also prevent the holding portion 2 a connecting the groove-shaped notch 2 and the cap 3 from being severely broken when a concentrated load is applied to the cap 3 before removal from above. .

In the present invention, the bend preventing piece provided on the tip end side of the cap 3 is formed on the tapered preventing piece 81 illustrated in FIG. 7 and the front wall corresponding to the tapered surface 81a of the piece 81. By forming the edge of the upright wall 5 on the tapered surface 5b, it is possible to prevent the cap 3 from being bent by the load.

[0027]

The present invention is as described above, and a removable cap for forming a wire opening is provided on the outer side of a lid attached to a cutout portion serving as a wiring outlet of a panel. Since it is provided at the facing position, when the lids are arranged to face each other, when the caps facing each other are removed, a large through hole having an opening area approximately twice as large as that of the cap forming one oval or the like is formed. Thus, the wiring can be drawn out reasonably and with good appearance.

Further, since a bend preventing piece formed by a rib-shaped standing wall is provided on the lower surface or the front end of the cap for the purpose of preventing the bend, the portion of the lid where the cap is disposed is a semi-circular shape provided on the panel. Even if the cap is not supported by the flange-shaped support side in the notch, there is no risk that the cap will break due to a vertical load and fall off from the groove-shaped notch.

Further, since the recesses for communication lines formed on the outer side of the lid are formed in one hole when they face each other,
A small amount of wire or fine cable can be pulled out of the lid without having to cut the cap from the grooved notch.
