Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wiring floor material that can prevent a cable accommodated in a wiring groove from jumping out.
[0002]
[Prior art]
Conventionally, as a flooring material for wiring, for example, there is one shown in Japanese Utility Model Publication No. 4-36351. As shown in FIG. 15, the wiring floor material 21 was composed of a rectangular block-shaped portion 22 and a protruding portion 23 extending in a bowl shape from the entire lower edge of the block-shaped portion 22 to the side. . The wiring flooring 21 was positioned and installed such that the overhanging portions 23 and 23 of the adjacent wiring flooring 21 and 21 faced each other. Thus, the space between the block-like portions 22 and 22 arranged apart by the protruding portions 23 and 23 to be abutted is a wiring groove 24 that accommodates a cable (not shown). The wiring groove 24 was covered with a cover plate 25 placed so as to be bridged over the upper edges of the block-like portions 22 and 22 sandwiching the wiring groove 24 after the cable was accommodated.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional wiring flooring 21, since the winding usually remains in the cable, the cable is not orderly accommodated in the wiring groove 24, but once accommodated in the wiring groove 24. Even in the case of a cable, there are cases where a number of locations where the cable jumps out of the wiring groove 24 in the wiring path occur as the wiring work proceeds sequentially. Therefore, after wiring the cable, it is necessary to store the protruding portion in the wiring groove 24 again. Further, when the protruding portion is accommodated in the wiring groove 24 again, the work is very troublesome so that the cable protrudes from the wiring groove 24 at a new location.
[0004]
Here, every time the cable is accommodated in the wiring groove 24, there is a method of covering the portion with the cover plate 25 to prevent the jumping out. In this case, the wiring work is performed while holding the cover plate 25 in addition to the cable. The work was extremely troublesome. Further, since the cover plate 25 is usually only placed on the wiring flooring 21, the cable may jump out of the wiring groove 24 so as to lift the cover plate 25. In this case, the cover plate 25 is again covered. The plate 25 had to be placed.
[0005]
The present invention has been made to solve the above-described conventional drawbacks, and an object of the present invention is to provide a wiring floor material that can easily prevent a cable accommodated in a wiring groove from jumping out. It is to provide.
[0006]
[Means for Solving the Problems]
In order to achieve the object, the wiring floor material according to the present invention has the following configuration. That is,
The flooring material for wiring according to the invention described in claim 1 is provided with a plurality of block-like portions to form a floor, and these block-like portions are arranged at predetermined intervals so as to form wiring grooves. And it has a pop-out prevention piece that extends from the block-like portion toward the wiring groove and covers the upper part of the cable accommodated in the wiring groove to prevent the cable from popping out. This pop-out prevention piece can be opened and closed between a position where the cable is opened so as to enter the wiring groove and a position where the cable accommodated in the wiring groove is prevented from popping out. Is formed. Then, the pop-out preventing piece is elastically returned from the opened position to the closed position.
[0007]
In this way, the wiring floor material has a plurality of block-like portions arranged at a predetermined interval, and a space between the block-like portions is a wiring groove. And a cable is put in a wiring groove | channel by making it the position which opened the protrusion prevention piece. Thereafter, the jumping-out prevention piece is set in the closed position, thereby preventing the cable accommodated in the wiring groove from jumping out. Here, when the cable is inserted into the wiring groove, the pop-out preventing piece is elastically returned from the opened position to the closed position, that is, automatically restored.
[0008]
Moreover, like the flooring material for wiring according to the second aspect of the present invention, the pop-out prevention piece is formed to be deformable so that it can be opened and closed between the opened position and the closed position. May be. Thus, the pop-out preventing piece is formed to be deformable, and can be opened and closed between the opened position and the closed position by the deformation.
[0009]
[0010]
Moreover, like the flooring material for wiring according to the invention described in claim 3 , it is desirable that the pop-out preventing piece is moved to the opened position by moving downward from the closed position. As a result, if the cable is pushed downward from above the jump-off prevention piece in the closed position, the jump-off prevention piece moves downward and becomes an open position, and the cable can be easily inserted into the wiring groove. Can be put.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a wiring floor material according to the present invention will be described with reference to the drawings.
[0012]
1 to 5 show a first embodiment of a wiring floor according to the present invention. In the figure, reference numeral 1 denotes a foundation floor surface, and 2 denotes a wiring floor material installed on the foundation floor surface 1. The wiring flooring 2 is made of, for example, a synthetic resin material such as polyethylene resin, and includes a block-shaped portion 3 having a predetermined height with a substantially square shape in plan view and a flat top surface so as to form a floor. The wiring floor materials 2 and 2 are arranged on the basic floor surface 1 at a predetermined interval so that the block-like portions 3 and 3 form wiring grooves 4 passing in the front and rear and right and left directions. Here, the block-like portion 3 is formed with a step portion 3b that is stepped down in a strip shape around the entire periphery of the edge of the upper surface 3a.
[0013]
The wiring flooring 2 has an anti-jumping piece 6 that covers the upper side of the cable 5 accommodated in the wiring groove 4 and prevents the cable 5 from jumping out at the upper part of the block-like portion 3. It is resin-molded integrally with the shaped part 3. This pop-out preventing piece 6 extends horizontally from the side surface of both ends of one side of the block-like portion 3 to the wiring groove 4 side so that the upper surface is flush with the stepped portion 3b, and the extending tip The portion is formed in a tapered shape with the upper surface side being an inclined surface 6a. And this protrusion prevention piece 6 is extended so that the front-end | tip which the other extension may adjoin with the front-end | tip of the other protrusion prevention piece 6 which the other wiring flooring 2 installed adjacently has. Also serving as a positioning means for forming the wiring groove 4.
[0014]
Further, the pop-out prevention piece 6 is formed with a thin-walled portion 6b serving as a hinge at the base end portion so that the lower surface side is cut out in a semicircular shape. Due to the elasticity, the thin-walled portion 6b can be bent and elastically bent. Thus, the jump-off prevention piece 6 is bent so as to be inclined downward, the both ends are opened, and the position where the cable 5 is opened so as to enter the wiring groove 4 (indicated by a two-dot chain line in FIG. 2) and the horizontal Open and close by rotating between the closed positions (shown by solid lines in FIG. 2) so that both ends abut against each other and the cable 5 accommodated in the wiring groove 4 is prevented from popping out. It can be moved. In this way, the jump-off preventing piece 6 becomes an opened position by moving downward from the closed position, and can be elastically returned from the opened position to the closed position.

Further, when the pop-out preventing piece 6 is in the closed position, the thin-walled portion 6b at the base end portion is connected to the block-like portion 3 on the upper surface side, and another wiring floor material on the lower surface side at the tip portion 2 is in contact with the other pop-out prevention piece 6 and collides with another wiring floor material 2 so that the tip portions of each other interfere with each other, the tip portion rotates downward about the thin portion 6b. Moment force acts like this. As a result, the pop-out prevention piece 6 moves so that the thin portion 6b is deformed and tilts downward (see FIG. 5).
[0016]
After the cable 5 is accommodated in the wiring groove 4, the adjacent wiring floor materials 2, 2 are connected by the connector 7 (see FIG. 3). The connector 7 is made of a belt-like plate material, and engaged portions 7a and 7a bent at a right angle downward are formed at both ends. On the other hand, in the wiring flooring 2, the engagement portion 7 a is inserted into the stepped portion 3 b of the block-like portion 3, and an engagement hole as an engagement portion that engages with the engagement portion 7 a. 3c is formed. Thus, the adjacent wiring floor materials 2 and 2 are connected to each other by the engaged portions 7a and 7a of the connector 7 being inserted into the engagement holes 3c and 3c of the wiring floor materials 2 and 2. The At this time, the step portions 3b and 3b are notched so that the upper surface of the connector 7 is flush with the step portions 3b and 3b. Thereafter, the upper surfaces of the wiring grooves 4 are closed so that the cover plates 8 and 8 are bridged over the step portions 3b and 3b of the adjacent wiring floor materials 2 and 2 (see FIG. 4). A carpet (not shown) is laid on the block-like portions 3 and 3 of the floor materials 2 and 2 and the cover plates 8 and 8.
[0017]
Next, the effect of the wiring flooring 2 having the above configuration will be described. The wiring flooring 2, 2 is installed such that the block-shaped parts 3, 3 are arranged on the basic floor surface 1 at a predetermined interval, and the space between the block-shaped parts 3, 3 is connected to the wiring groove 4. It has become. Then, when the cable 5 is pushed downward from above the pop-out preventing pieces 6 and 6 extending horizontally from the block-like portions 3 and 3 to the wiring groove 4 side, the pop-out preventing piece 6 , 6 are deformed and moved downward and become open positions. When the cable 5 enters the wiring groove 4, the pop-out preventing pieces 6 and 6 are elastically returned from the opened position to the closed position, that is, automatically returned. In this way, simply by pushing the cable 5 downward, the pop-out preventing pieces 6 and 6 can be opened so that the cable 5 can be put into the wiring groove 4 and then prevented from popping out. Since the pieces 6 and 6 are automatically returned from the opened position to the closed position, the cable 5 can be easily accommodated. Thus, the cable 5 is accommodated in the wiring groove 4, and the cable 5 is easily prevented from jumping out of the wiring groove 4 by the pop-out preventing pieces 6 and 6 in the closed position.
[0018]
Further, the jump-out preventing piece 6 extends so as to abut against the other jump-out preventing pieces 6 of the other wiring flooring 2 installed adjacent to each other, and is positioned for forming the wiring groove 4. Since it is a means, the wiring groove | channel 4 is ensured reliably. Moreover, since the pop-out preventing piece 6 is in an upper position that covers the upper side of the cable 5, it is easy to visually check the contact state, and even after the cable 5 is placed in the wiring groove 4, The cable 5 does not become an obstacle, and the contact state can be easily confirmed by visual observation as to whether the positioning is properly performed.
[0019]
Further, when the wiring floor material 2 expands due to an increase in temperature, the jump-out preventing piece 6 that comes into contact with another jump-out preventing piece 6 that is installed next to the other wiring floor material 2 is It collides with another jump-off preventing piece 6 of the wiring floor material 2 and deforms and moves downward, that is, tilts into the wiring groove 4 (see FIG. 5). Accordingly, the expansion of the wiring floor material 2 can be absorbed by the deformable jump-out preventing piece 6, and the entire floor is not warped.
