2. Description of the Related Art Wiring floors with wiring grooves have become popular recently. Conventionally, a grid-shaped wiring groove that simply crosses the cross shape has been used as a wiring path. At the intersections of the crosses, there are some cases where the corners of the floorboard are rounded or slightly cut, but the radius of curvature is usually about 5 mm and the corners are cut about 5 mm to eliminate sharp corners. It is difficult to bend a cord at a right angle in a narrow wiring groove having a width of 5 to 10 centimeters. In particular,
In the case of a hard cord, it could not be bent.

[0003]

OBJECTS OF THE INVENTION The present invention solves these difficulties,

Embodiment 2 FIG. 7 shows another example of the corner floor plate 1. A small block floor board with a side of 5 cm
One corner of a square aggregate floorboard B formed by connecting the above is cut into corners to form a substantially pentagonal corner floorboard 1. It is formed by installing deformation blocks along the corners. In addition to this, as the corner cutting floor plate, it is possible to use a floor plate made of a solid or hollow flat plate with bolt legs attached to each corner for height adjustment function, but at least one corner cutting If it is applied, the material is not specified.
Normally, the distance from the corner to be cut to the corner cut point is ideally about one half of the width of the formed wiring groove, but about one fifth, that is, for the wiring groove having a width of 10 cm. 2
Even a centimeter corner cut can be expected to have a considerable effect.

[0016]

[Embodiment 3] A large corner cut inevitably results in a large intersection. In the case of a cross lid corresponding to a large intersection, the central portion is weak against the load from above. In order to deal with such a situation, an example of a cross lid having a reinforced central portion is shown.

As shown in FIG. 8, two facing corner cutting edges 62 of a face plate 10 made of a galvanized steel plate having a thickness of 3 mm and having a size to be fitted into an octagonal shape of a crossing are formed into two corner cutting edges. The width is about 5 mm and the extension is bent downward at a right angle to form the locking edge 51. A semi-long round notch 63 having a width of 20 mm and a length of 20 mm is provided at the center of the one corner cutting edge 62 having no locking edge.

As shown in FIG. 9, using the same material as above, the width is the same as that of the two corner cutting edges 62 not provided with the locking edges,

As shown in the drawing, a reinforcing plate 64 is welded to the back surface of a front plate having locking edges provided at two locations to form a cross lid 6. When welding, the side with the locking edge of the reinforcing plate,
Stack on the side of the surface plate that does not have the locking edge. By stacking in this manner, locking edges are attached to all corner cutting edges around the surface plate. Further, since the center of the face plate is doubled, it is strong against a load from above and is convenient for use in a large intersection. The method of using the cross lid is the same as that in the first embodiment.

When the cross lid is formed in this manner, as shown in FIG.
As shown in 0, the large cutout of the face plate 10 is
Overlying the four small notches, a wiring outlet 65 is formed, but at the same time, a narrow horseshoe-shaped loading edge 66 of about 2 mm width is formed around the notch of the reinforcing plate.

A plastic cap 67 having the same thickness as the thickness of the surface plate is fitted in the notch of the surface plate as shown in FIG. 11, and is placed on the loading edge for easy attachment / detachment. It is good to block the outlet. An insertion groove 68 may be provided on the back surface of the cap of the wiring outlet so that the cap is inserted and fixed in the above-mentioned load edge. Alternatively, a deep cut groove 69 may be provided along the edge of the cap, and a part may be easily cut off by using pliers or the like.

[Embodiment 4] FIG. 12 shows a small block floorboard 1
4 shows a state in which four corner-cutting floorboards 14 formed by cutting one corner of the aggregate floorboard B consisting of 5 are installed at intervals to form the wiring groove and the intersection 3. A pillar 16 having a circular cross-section and having the same height as the surrounding floor boards is erected at the intersection. The four corner-cutting floor plates and the pillars are arranged in this manner, and the lower surfaces are connected by the sheet-like material 21. 5 mm wide and 3 deep along the edges of the aggregate floorboard B and the columns 16.
A millimeter loading edge 66 is provided.

As shown in FIG. 13, it is made of a rigid flat plate having a thickness of 3 millimeters, and has a substantially octagonal shape which is substantially the same as that of the above-mentioned intersection, and is fitted in the outer edge of the above-mentioned load edge 66 at the center of the pillar. Prepare the cross lid 6 provided with the round hole 60 to be fitted,
The intersection lid is put on the intersection. The cross lid is formed at the same level as the surrounding aggregate floorboard. Further, since the center portion of the cross lid is supported by the pillar, the force from above can be counteracted even if the width of the cross road is wide.

[0024]

[Embodiment 5] Using a corner floor plate as shown in FIG.
As shown in Figure 4, four corner-cut floorboards are abutted to form a floorboard group. A large number of such floor board groups are laid out by providing wiring grooves each having a width of 10 cm on four sides other than the corner cut sides. An octagonal intersection is formed where the wiring grooves intersect in a cross shape. FIG. 14 shows another example of the cross lid 6 for such an intersection.

The four corner cutting edges 62 of the face plate 10 made of a zinc-plated steel plate having a thickness of 2 mm and having a size to fit in the octagon of the intersection are approximately 3 cm in strip shape with the width of the corner cutting edges being the same. And the extended portion is bent downward at a right angle to form the support leg 13. A square opening 7 having a side of 7 cm is provided in the center of the face plate. The opening is punched out into a shape as shown in FIG. 15, and a reinforcing edge piece 71 having a width of 5 mm and a full width of the edge is provided on the two opposite sides. On the other two sides, an opening leg piece 72 having a length of 3 cm is provided inside the reinforcing edge. Bend these reinforcing edge pieces and opening leg pieces at right angles to the reinforcing edge,
Use open legs.

As shown in FIG. 14, a flat plate 8 having the same height as the cross lid and internally fitting in the opening and having a wiring connecting mechanism such as a connector and an outlet is prepared. The opening 7 is detachably loaded and finished flat. When necessary, the cord passing through the wiring groove can be connected to the bottom of the wiring connection mechanism, and the connected cord can be pulled out onto the floor through this opening.

As another example of the cross lid, a face plate having a thickness of 5 is used.
It is made of a flat plate with a high rigidity of millimeter, and the corner cutting edge is provided with a separately formed insertion edge with an L-shaped cross section, and it is installed at the peripheral edge of the cross groove and inserted into the support edge. You may use.

[0028]

Since the present invention is constructed as described above, it has the following effects. 1 A wide wiring space can be formed by using a corner-cutting floor plate to form a corner-cutting wiring groove. 2 When bending a hard cord, it cannot be bent unless the bend R is large, but since there is a corner cut, it is possible to take a large R even if the wiring groove itself is relatively narrow. 3 In the case of a crossroad with no corner cuts, there was no good way to support it even when trying to put a lid on the crossroads. In the case of the corner cut wiring groove, since the lid can be supported by the corner cut edge, an independent lid at the intersection can be formed. If an independent lid can be prepared for the 4 intersections, it is convenient to attach a wiring outlet to the intersection lid and pull out the cord from the wiring groove.
