Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double floor formed by supporting and laying a large number of rectangular floor panels adjacent to each other at a certain height on the floor base, and a rectangular notch provided on each side edge of two adjacent floor panels. The present invention relates to a lid that is attached to rectangular openings whose parts face each other.

[0002]

[Industrial applications]

 Square floor panels for double floors usually have a rectangular cutout at the center of the two opposite edges to serve as a handle for the double floor, and two double cutouts facing each other during double floor molding. Depending on the part, it is used as a square opening for under-floor wiring extraction holes, wiring fixture mounting holes, etc. On the other hand, the rectangular opening that is not used for this purpose covers the floor upper surface with a lid such as a metal plate or synthetic resin plate. It is closed so that it becomes one (for example, see Japanese Utility Model Laid-Open No. 63-85753, Japanese Utility Model Laid-Open No. 1-84515). Further, a semicircular cutout is provided on the side edge of the lid, and the two lids are butted against each other and fitted into the rectangular opening, so that the semicircular cutout covers the elliptical passage opening. It is already possible to form a surface or a lid that can easily cut off a part of one side edge surface of the lid with a fine groove cutting line and can correspond to both a wire passage part and a non-wire passage part. Proposed.

[Problems to be solved by the device]

 The lid with the above-mentioned wiring opening covers the square opening of the double floor closest to the equipment placed on the double floor, and the underfloor wiring can be directly connected to the equipment through the wiring opening. There is usually a floor finish sheet such as carpet or tile carpet laid on the lid to hold the lid in a stable manner. In case of hitting, it is necessary to have a blind lid without a passage opening, and even in the case of a lid where a passage portion can be formed by the above cutting, prepare a non-cut lid that does not form a passage portion. In this case, however, the problem that the compressive strength of the resectable part becomes insufficient was unavoidable.

[0004]

[Means for Solving the Problems]

 The present invention is a lid to be attached to the rectangular cutouts provided on the side edges of the two floor panels forming the square opening of the double floor as described above. The present invention solves the handling problem of preparing two types of conventional lids that can be used as any of the lids. That is, the present invention is a metal plate molded body in which a blind lid plate portion and a passage lid plate portion having a cutout opening are vertically parallel to each other and connected by a vertical wall at the center of one side edge of each. A lid for a double floor panel cutout portion, characterized in that a facing distance between the blind lid plate portion and the wiring lid plate portion is equal to or larger than a size obtained by adding a floor panel thickness of an object to be adhered and an insertion wire diameter. The gist also includes the lid for the double floor panel cutout part in which the electrodeposited flock layer is provided on the entire outer surface of the vertical wall.

A floor panel for a double floor is usually a rectangular hard plate having a side length of 30 to 60 cm, an opening in one direction of 5 to 10 cm and a depth of 2 in the opposite direction at the center of the two opposite sides. ． A rectangular cutout of 5 cm is provided, and a groove step portion with a width of 3 to 6 mm and a depth of 1 to 3 mm for mounting a lid plate edge is formed on the upper surface of the floor panel along the peripheral green of the cutout. It is commonly used. Therefore, both the blind cover plate part and the line cover plate part of the lid are dimensioned so that the three edges other than the vertical wall connecting edges can be properly mounted on the groove step part of the rectangular cutout peripheral edge of the floor panel. The blind cover plate covers the entire notch of the floor panel, and the wire cover plate part is a part of the cover plate cut off from the line part. It covers the notch. It is desirable that one or two cutout openings for the wire provided on the edge of the lid plate portion for the wire are provided by cutting off the edge portion other than the vertical wall connecting edge.

[0006] The blind lid plate portion and the passage lid plate portion having the above-mentioned size and shape are held by vertical walls that are connected at the center of one side edge so as to face each other vertically and in parallel. It is necessary for inserting the electric wire that the facing interval of the plate portions is equal to or larger than the sum of the thickness of the floor panel to which the lid is attached and the diameter of the electric wire that passes through the cutout portion of the floor panel. Along with this, both sides of the above vertical wall should have open side edges of sufficient width, and this open side edge should be inserted from diagonally above the square opening edge of the double floor, and the upper and lower lids should be inserted. The lid can be inserted between the plates so that the edge of the floor panel is sandwiched, and the inserted lid can be easily removed and removed obliquely upward.

The lid of the present invention is manufactured by die-cutting and bending of a metal plate, and the lids are paired in pairs, and each lid has a double floor with a square opening. The rectangular notches of the flannel are inserted so that the outer surfaces of the vertical walls of both lids abut. If the vertical walls of both lids mentioned above make contact vibrations due to an earthquake or the like, an unpleasant metallic sound is generated.Therefore, it is desirable to provide an electrodeposited flocked layer in which short fibers are densely planted on the outer surface of each vertical wall of both lids. Also, this makes it possible to maintain a stable fitted state by elastically contacting both lids in the covered state.

[0008]

[Action]

 In the double floor panel notch lid of the present invention, the blind lid plate portion and the passage lid plate portion are vertically opposed to each other and connected by vertical walls at the center of one side edge of each lid plate portion. Since the facing distance between both lid plate parts is greater than or equal to the size of the floor panel thickness of the object to be adhered and the insertion wire diameter, the square opening of the formed double floor is The two lids can be inserted in a slanted manner one after another and moved in a direction perpendicular to the vertical wall, so that the two lids can be combined to form a stable lid state. One or both of the blind lid plates inserted under the floor panel or the line lid plate inserted under the floor panel can be connected to the bottom surface of the floor panel by placing the wire lid plate on the upper surface. The vertical space in which the cables are inserted is maintained, and the underfloor wiring is routed through the space through the notch opening in the top cover plate. It is those that can be drawn on. It is also possible to place the blind lid plate portion on the upper surface of both of the two lids to close the rectangular opening of the double floor.
