[0002]
[Prior art]
In recent years, a large number of various electric and electronic devices are used in rooms such as offices provided in buildings. The indoor electric wires and communication lines used for these are wired at a predetermined location in the space between the foundation floor surface of the building and the free access floor constructed above it, and placed at the desired position of the panel members constituting the free access floor. A terminal portion of the wiring cable can be taken out to the upper surface of the floor from the provided wiring outlet.
[0003]
These conventional free access floors include, for example, as shown in FIGS. 6 to 8, a square main body panel 3 having a plurality of legs 2 arranged at predetermined intervals on a foundation floor 1 of a building, and these The rectangular groove panel 5 is provided to cover the groove 4 formed between the main body panels 3 and 3 and the square auxiliary groove panel 5a is provided between the groove panels 5 and 5. In the groove 4, various cables 6 are accommodated.
[0004]
The main body panel 3 uses a molded panel made of synthetic resin or the like whose back and peripheral surfaces are reinforced with ribs 7 for integrally forming the leg 2 and for weight reduction, and the groove panel 5 is used for wiring. In view of the necessity of ensuring the space as large as possible and maintaining the strength, a product obtained by pressing a metal plate is used. And in the desired position of the peripheral part of the groove panel 5, the taking-out port 8 which pulls out the terminal part of the cable 6 connected to an electric and electronic device is notched from the surrounding wall part 9 to the top-plate part 10, and is provided. .
[0005]
The cable 6 wired in the groove is drawn out from a take-out port 8 in the vicinity of installed electrical and electronic equipment, and used by being connected to the equipment. Accordingly, since the wiring cable does not crawl on the outer surface of the floor, the appearance of the room is good, and a large number of cables can be accommodated in the groove 4, so that a large number of electrical and electronic devices can be accommodated.
[0006]
[Problems to be solved by the invention]
However, when the metal panel is pressed to form the groove panel 5, the wiring outlet 8 in the conventional free access floor is formed by punching at the same time, and the edge of the metal plate serving as the outlet 8 The corner portion 11 is an acute corner portion in which a cutting trace remains during punching.
[0007]
Therefore, during the operation of pulling out the cable 6 from the groove 4, the surface of the cable 6 hits against the acute angle portion of the edge 11 of the metal plate and the smooth pulling operation is impaired, and the connection operation with each device is performed. At this time, depending on the method of an unskilled operator, there is a concern that the surface of the cable 6 may be rubbed and damaged by the sharp edge 11.
[0008]
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a wiring outlet structure in which a cable in a groove can be smoothly taken out and there is no fear of damaging or damaging the cable even during connection work with a device. It is said.
[0009]
[Means for Solving the Problems]
The present invention relates to a free access floor formed by connecting a plurality of floor panel body panels and a plurality of metal groove panels covering a wiring groove formed between the body panels. An opening recess is provided at the peripheral edge of the panel and opens to the outer peripheral surface and the upper and lower surfaces, and a portion corresponding to the opening recess of the peripheral wall portion of the groove panel is bent inward from the peripheral edge of the top plate portion to form an inclined surface. The above-described problems have been solved by using a wiring outlet having a configuration in which a concave portion is formed.
[0010]
The angle of the inclined surface formed in the opening recess is preferably about 40 degrees .
[0011]
DETAILED DESCRIPTION OF THE INVENTION

The basic structure of the free access floor including the main body panel 3, the groove panel 5, and the auxiliary groove panel 5a has already been described. In the following drawings, the same reference numerals are given to the overlapping parts, and the description thereof is omitted.
[0013]
As shown in FIG. 2, the main body panel 3 is formed using a synthetic resin material in the same manner as in the conventional example, and a flat square panel portion 12 whose back surface is reinforced with ribs 7, its corner portions 13, and each side 14. A leg portion 2 in which a part of the top surface 15 protrudes from the corner portion 13 and each side 14 is integrally formed and protruded at the center. The leg portions 2 may be provided separately and fixed by appropriate means such as adhesion, welding, and screwing.
[0014]
A fitting groove 16 for connecting the groove panel 5 is provided on each corner portion 13 lower than the upper surface of the panel portion 12 and on the top surface 15 of the leg portion 2 on each side 14.
[0015]
Further, at a desired position of the peripheral edge of the main body panel 3, one or more opening recesses 17 are provided that open to the outer peripheral surface and the upper and lower surfaces.
[0016]
On the other hand, the groove panel 5 is obtained by pressing a metal plate such as a steel plate or an aluminum plate, and the peripheral wall portion 9 is vertically bent by bending the peripheral edge portion of the top plate portion 10. A portion corresponding to the opening recess 17 of the main body panel 3 is bent about 40 degrees inward from the peripheral edge of the top plate portion to form a concave portion 19 of the inclined surface 18.
[0017]
The concave portions 19 of the peripheral wall portion 9 of the groove panel 5 are provided at a plurality of locations so as to correspond to the opening recesses 17 of the main body panel 3 regardless of the direction of the groove panel 5 to be inserted when assembled as a free access floor. ing.
