Description

[Detailed description of the invention]

[0001]

[Industrial application] The present invention uses a large number of square floor panels,
In a double floor formed by laying adjacently at a fixed height on the floor base, a rectangular notch provided at each side edge of two adjacent floor panels covers a rectangular opening facing each other. It is about.

[0002]

2. Description of the Related Art A rectangular floor panel for a double floor is usually provided with a rectangular notch at the center of two opposing side edges to serve as a handle for handling. The two cutouts are used as a rectangular opening for the underfloor wiring draw-out hole, wiring equipment mounting hole, etc. On the other hand, the rectangular opening not used in this way is covered with a lid made of metal plate, synthetic resin plate, etc. (See, for example, Japanese Utility Model Laid-Open No. 63-85753 and Japanese Utility Model Laid-Open No. 1-84515). In addition, a semicircular notch is provided on the side edge of the lid of the previous period, the two lids are butted and fitted into the square opening,
An elliptical through-hole opening with a semicircular notch is formed in the lid surface, or a part of one side edge surface of the lid can be easily cut off by a narrow groove cutting line. It has already been proposed to use a lid that can correspond to any of the line portions.

SUMMARY OF THE INVENTION According to the present invention, the lid is turned upside down as a lid which is attached to rectangular cutouts respectively provided at the side edges of two floor panels forming the rectangular opening of the double floor. The present invention solves the above-mentioned problem of handling by preparing two types of conventional lids as a lid which can be easily formed into both a blind lid and a wiring lid. That is, the present invention is a blind cover plate, wire-passing lid plate portion having a notch opening, a metal plate made moldings joined by a vertical wall in each of the one side edge center by vertically opposed parallel, the The vertical wall is
Make sure there are enough open edges on both sides and
The gap between the blind cover plate portion and the cover plate portion for communication is not less than the sum of the thickness of the floor panel to be adhered and the diameter of the current-carrying wire. The gist also includes a lid, and further includes a double floor panel cutout lid provided with an electrodeposited flocked layer on the entire outer surface of the vertical wall.

[0005] Floor panels for double floors usually have a side length of 30-6.
A rectangular hard plate of 0 cm is used, and a rectangular notch having an opening in the mold direction of 5 to 10 cm and a depth in the opposite side of 2.5 to 5 cm is provided at the center of two opposing sides. Generally, a groove having a width of 3 to 6 m and a depth of 1 to 3 mm for mounting a lid edge is formed on the upper surface of the floor panel along the periphery of the portion. Therefore, each of the blind cover plate portion and the wire cover plate portion of the lid is dimensioned so that the three edges other than the vertical wall connecting edge fit into the groove step around the rectangular cutout portion of the floor panel. The blind cover plate covers the entire cutout of the floor panel, and the cover plate for the wire is a floor panel other than the cutout opening for the wire with a part of the cover plate cut off from the edge. To cover the notch. It is desirable that one or two cutout openings for the communication line provided at the edge of the cover plate portion for the communication line be cut off at edges other than the vertical wall connecting edge.

The blind cover plate having the above-mentioned size and shape is held by a vertical wall connected at the center of one side edge thereof so as to be vertically opposed to and parallel to each other. It is necessary for the insertion of the electric wire that the facing distance of the cover is not less than the sum of the thickness of the floor panel to which the lid is attached and the diameter of the electric wire to be inserted through the cutout of the floor panel. Along with the vertical wall, open side edges of sufficient width are provided on both sides of the vertical wall, and the open side edge is inserted obliquely from above the rectangular opening edge of the double floor, and between the upper and lower lid plate portions. Thus, the lid is inserted so as to sandwich the edge of the floor panel, and the inserted lid can be easily removed obliquely upward and removed. Up
The sufficient width of the open side edge described above is the square opening edge of the double floor.
To facilitate the insertion and removal of
When two notch lids are installed as a set,
On the side to facilitate wiring
The width of the vertical wall is narrow enough to maintain the shape retention of the lid.
Is desirable.

The lid of the present invention is manufactured by die cutting and bending a metal plate, and the lids are made into a pair, and each lid is formed of a double floor having a rectangular opening. Are inserted into the rectangular notches so that the outer surfaces of the vertical walls of both lids are in contact with each other. When the vertical walls of both lids vibrate in contact with each other due to an earthquake or the like, an unpleasant metal sound is generated.Therefore, it is desirable to provide an electrodeposited flocking layer in which short fibers are densely planted on the outer surfaces of the respective vertical walls of both lids. Thereby, a stable fitted state can be maintained by the elastic interview of both lids under the covered state.

[0008]

SUMMARY OF Invention The present invention of a double floor panels notch lid are linked with each one side edge center of hunting case plate portion by the vertical wall cover plate portion for blind cover plate portion and the wire-passing the up and down opposed parallel , Both of its vertical walls
The open side edge of a sufficient width is provided on the side, and the facing distance between the two cover plates is set to be equal to or larger than the sum of the thickness of the floor panel to be attached and the diameter of the insertion conducting wire. The two lids from the upper surface of the double floor are inserted obliquely into the rectangular opening of the floor in order, and are moved in the direction perpendicular to the vertical wall. In this case, one or both of the two lids can be placed on the upper surface by placing the wiring lid plate on the upper surface, so that the other blind lid plate or the lower lid inserted below the floor panel can be placed. The wire cover plate maintains the vertical space where the electric wire is inserted between the lower surface of the floor panel and the underfloor wiring through the space through the cutout opening of the wire cover plate on the upper surface. You can do it. In addition, both of the two lids can be closed with the blind lid plate positioned on the upper surface to close the rectangular opening of the double floor.
Pulling up and removing the lid from the above-mentioned cover state also from the double floor upper surface
Operation can be easily performed, and conversion of the cover state can be performed.
It can be done easily.
