Detailed Description of the Invention

[0001]

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

[0002]

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

On the above-mentioned free access floor, power cables and signal cables for computer terminal equipment and communication equipment can be freely wired in the space under the floor, but both cables are arranged on the upper surface side of the floor. Since it is necessary to take out the wiring under the floor to the upper surface side of the floor in order to connect with the terminal equipment, communication equipment, etc., in the conventional floor panel, the wiring outlet is formed in various modes.

In the conventional floor panel, the wiring outlet has a shape in which a semi-circular or semi-elliptical shape or a rectangular cutout is formed on the outer periphery of the floor panel. Several structures having a structure in which a lid that allows a passage opening to be formed later is mounted on the cutout portion have been proposed, and some of the same type have already been put into practical use.

As an example of a conventional product, as shown in FIG. 11, a lid C made of synthetic resin is attached to a notch K formed by recessing the inside of the panel P on the outer peripheral edge of the panel P.
Since the through hole H is formed later, a fine groove-shaped cut S along the shape of the through hole H is formed in the lid C, and the minute connection portion L is left on the cut S when the lid C is formed. Formed,
When the wire is passed, the cap-shaped small piece Pi surrounded by the cut S is removed to form the wire hole H.

However, with the above-described form and structure of the passage opening H, the opening area of the passage opening H cannot be so large, so that the amount of cables that can be pulled out from one passage opening H is limited. There was a limit and it was a little difficult to use. In particular, when the cutouts K, K of the adjacent panels P are arranged facing each other, in order to pull out a considerable amount of cable, the cables are separately pulled out from the four wire passages H of the two lids C. Since it has to be done, not only is it troublesome, but also the appearance is not preferable.

Further, the lid C mounted on the mounting flange (not shown in FIG. 11) of the cutout K opened in a substantially semicircular shape on the outer periphery of the floor panel P is also wired to the passage opening H. There is also a problem that when the cable or the like is inserted, or when the cable is pulled from above after the insertion, the cable is easily caught by the flange. In order to avoid this, in conventional products, it is essential to take countermeasures such as adding a radius to the edge of the mounting flange.

[0008]

SUMMARY OF THE INVENTION In view of the above problems of the wiring outlet and the lid of a conventional free access floor panel, the present invention provides a free access floor panel with a cutout portion for its wiring. When placed facing each other, the passage openings of the facing panels are integrated so that they can accommodate the insertion of a large amount of cables, and when pulling out the cables, the cables are caught 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 without fear.

In FIGS. 1 to 4, reference numeral 20 designates a wiring formed in a manner of being recessed from the upper surface of the panel P at at least one location or more locations on the outer periphery of the floor panel P having a substantially square plane. 1, which is a cutout portion for taking out, which is provided with a cutout groove 2 and a cap 3 which are substantially U-shaped in a plan view for forming a through hole H which will be described later.
An example of the lid 1 of the present invention shown in FIG. 2 is removably mounted.
This point will be described below.

[0012] First, the cutout portion 20 of the panel P in FIG. 4, the support sides 21 of the lid 1 down by one step from the upper surface of the panel P in the circumferential edge of that are formed in a flange shape. Then, on the left and right peripheral sides of the support side 21, the locking claw pieces 9 of the lid 1 described later are fitted and guided, and the locking notch for holding the lid 1 in the notch 20 is provided. 21a and 21b are formed.

The lid 1 of the present invention, which is attached to the cutout portion 20 for taking out the wiring of the panel P, has a plane shape which fits within the outer contour of the cutout portion 20 and has the panel P on the outer periphery thereof.
There is provided a cap 3 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 by 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 is detached from the lid 1 and thereby the U-shaped flat surface. The line mouth H is formed. The shape of the holding portion 2a is not limited to the above-mentioned strip-shaped holding portion, but may be a half punch-shaped holding portion in which a thin bottom is left in the groove-shaped notch 2 or a combination thereof. Good. In addition to the U-shape, the groove-shaped notch 2 that forms the passage opening H may have an arbitrary planar shape such as a semicircular shape, a triangular shape, or a rectangular shape.
Further, the size and position of the notch 2 are not limited to those in the embodiment.

Reference numeral 4 denotes a rib-shaped standing wall having a substantially U-shape in a plane, which is erected so as to surround the groove-shaped notch 2 on the back surface of the lid 1.
5 is the standing wall 4 near the outer side 1a located at the front end of the lid 1.
The standing wall 6 has a front wall shape integrally formed with the standing wall 6, and is a reinforcing standing wall continuously formed on the two standing walls 4 and 5 and formed at a substantially central portion of the lid 1, and each standing wall 4 to 6 is a lid 1. It is for supporting a vertical load applied to the lid 1 without warping the lid 1.

Reference numeral 7 denotes a recess for wire passage formed between the left and right groove-shaped notches 2 holding caps 3 formed at two places on the left and right on the outer side 1a of the lid 1, and 8 denotes the cap 3 It is a rib-shaped support piece formed substantially vertically in the center of the back surface along the lengthwise direction of the cap 3 at the same height as the standing walls 4 to 6. The planar shape of the recess 7 may be any planar shape such as a semicircle or a V shape. Further, the number to be formed can be arbitrarily selected according to the length of the extra length portion on the outer side 1a of the lid 1.

In the lid 1, reference numeral 9 denotes locking claw pieces for attaching and detaching the lid, which are formed on the left and right sides of the back surface of the lid 1 so as to have a substantially elongated U shape when viewed from the front facing downward. Also, the stepped portion 9a formed by projecting to the outside of the claw piece 9 is elastically locked to the locking notches 21a and 21b in the panel P. Reference numeral 10 denotes an operation hole having a substantially semicircular shape in a plane for holding and operating the locking claw piece 9 from the upper surface side of the lid 1 with a finger.

By the 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, other flat lids, such as semi-circular and triangular shapes,
It can be applied as is. Of course, the planar shape of the lid 1 corresponds to the planar shape of the cutout portion 20 on the panel P side, so that the planar shape of the cutout portion 20 and the lid 1 may correspond to any planar shape. Must have a shape with. The lid 1 is preferably made of synthetic resin in terms of molding, but 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 has a notch portion 20 serving as a wiring outlet of the floor panel P shown in FIG.
It is mounted and used as shown in FIG. When the lid 1 is attached to the cutout portion 20, the left and right locking claw pieces 9 and 9 formed on the back surface of the lid 1 are fitted and guided in the locking cutouts 21a and 21b of the cutout portion 20. 1 is easy to install, and also
After the mounting, the stepped portions 9a, 9a of the locking claw pieces 9, 9 have the notches 21.
Since it is locked by a and 21b, there is no danger of it coming off due to vibration or the like. Then, in this mounting mode, when it is desired to form the passage opening H in the lid 1, the cap 3 is separated from the lid 1 by hitting or cutting the holding portion 2a of the groove-shaped notch 2. , The passage opening H is formed.

The lid 1 for the wiring outlet of the present invention is the lid 1.
In this embodiment, the cap 3 having a substantially U-shaped plane is only supported by the groove-shaped notch 2 through the holding portion 2a, that is, the cap 3 is provided in the notch 20 of the panel P. Since it is not supported by the flange-shaped support side 21,
Before separating the cap 3 from the lid 1, the cap 3
If a concentrated load is applied to the holding part 2a, it will not be able to withstand the load,
It may be disconnected.

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 if a concentrated load is applied such that the heel h of the high heel rests on the cap 3, the lower portion of the side end 8a of the support piece 8 contacts the rib-shaped standing wall 4. Since it is supported, even if a part of the holding portion 2a of the groove-shaped notch 2 is about to be cut, the tear does not occur, and even if the cap 3 receives such a concentrated load,
There is no danger of it coming off the groove-shaped notch 2.

In the present invention, the cap 3 is provided so as to face the side of the outer side 1a of the lid 1 (the side on the same side as the outer periphery of the panel P). When the lids 1 and 1 face each other as illustrated in 7,
The caps 3, 3 are positioned so as to face each other, whereby two U-shaped groove-shaped notches 2, 2 facing each other are provided.
Will form one oval notch. Of course,
If the groove-shaped notch 2 is semicircular or triangular, it becomes a circular or quadrangular notch.

As a result, when the caps 3 and 3 facing each other are removed from the lids 1 and 1 facing each other, a single elliptical wire outlet H'for taking out the wiring is formed. It is possible to pull out a large amount of wiring from one of the outlets 1 and 1, so that not only can the wiring work be performed rationally, but also the wiring to be pulled out looks good.

Further, since the wire outlet H for taking out the wiring formed by removing the cap 3 is surrounded by the rib-shaped standing wall 4 having a U-shaped plane, the installation state of the standing wall 4 is drawn out. Since the wirings play the role of a guide for the wirings, the situation that the wirings to be drawn out are not caught on the flange of the cutout portion of the panel P as in the conventional product will not occur. The lower end 4a of the standing wall 4 can be rounded so that the standing wall 4 can better serve as a wire guide. The standing wall 4 is a wiring that is drawn to the upper surface side of the panel P.
Since it does not directly contact the component member of, specifically, the flange-shaped support side 21 made of metal, the burr remaining on the support side 21 does not damage or break the coating of the wiring at the time of drawing, It is electrically safe. In this respect, it is particularly useful when drawing out a wiring whose coating is broken.

Further, in the present invention, on the side of the outer side 1a of the lid 1,
By providing the recess 7 for the wire passage, in the case of a small amount of wiring or a thin cable, the wiring can be pulled out from this 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 into one hole, so that a larger amount of wiring can be formed. This is advantageous from the viewpoint of safety in that it has the advantage that it can be taken out, and that the drawn wiring does not have to come into contact with the edges of the panel constituent members (mainly made of metal).

In the present invention, instead of the rib 8 for preventing the bending of the cap 3 before removal described above, or in addition to the rib 8, the bending prevention of the cap 3 as shown in FIG. 6 is performed. The piece 8 ′ may be hung on the front end face side of the cap 3. In this case, the receiving projection 5a or 4b may be provided on the front end surface of the standing wall 5 or the standing wall 4. This bending preventing piece 8'can also prevent the breakage of the holding portion 2a connecting the groove-shaped notch 2 and the cap 3 when a concentrated load is applied to the cap 3 before removal from above. .

In the present invention, the bending prevention piece provided on the tip end side of the cap 3 is formed on the tapered tapered prevention piece 81 illustrated in FIG. 7, and the front wall shape corresponding to the tapered surface 81a of the piece 81 is formed. By forming the edge of the standing wall 5 on the tapered surface 5b, it is possible to prevent the cap 3 from bending due to the load.

[0027]

The present invention is as described above, and the removable cap for forming the passage opening is attached to the outer side of the lid attached to the cutout portion serving as the wiring outlet of the panel. Since the caps are provided so as to face each other, when the lids are arranged so as to face each other, when the caps facing each other are removed, a large passage opening having an opening area approximately twice as large as that of the cap, which is one oval or the like, is formed. As a result, the wiring can be drawn out reasonably and visually.

Further, since a bending prevention piece 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 bending, the portion where the cap is arranged in the lid has a semicircular shape provided on the panel. Even if the cap is not supported by the flange-shaped support side in the notch portion, there is no possibility that the cap will break due to a vertical load and fall out from the groove-shaped notch.

Further, since the passage recesses provided on the outer side of the lid are also formed into one hole when they face each other,
Small amounts of wire or fine cables can be pulled out of the lid without having to separate the cap from the groove cutout.
