Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the lead-out portion of an undercarpet cable.

Generally, undercarpet cables are installed under the carpet on the floor.
It is designed so that it can branch out as needed, penetrate the carpet, and stand up on the top surface of the carpet. The cable pull-out hole opened in the carpet needs to be as small as possible, and moreover, it needs to be able to maintain an orderly appearance even after changing the pull-out position. However, in the past, it was necessary to cut off a part of the carpet to accommodate the cable pull-out position, and therefore, after the cable pull-out position was changed, the cut-off portion remained on the carpet, resulting in an unfavorable appearance.

The present invention was developed in view of the above situation, and provides an undercarpet that can reliably fix the cable pull-out position and maintain an orderly appearance even after the pull-out hole formed in the carpet has been changed. Its purpose is to provide a cable outlet.

The undercarpet cable pullout part of the present invention is formed by pulling out the undercarpet cable laid under the carpet laid on the floor surface onto the floor surface, and has a built-in cable part with a U-shaped cross section, and a fixing metal fitting having a bottom fixing surface fixed to the floor surface parallel to the bottom surface of the U shape at the open end of the U shape, and a fixing metal fitting having a cable pull-out hole opened in the bottom surface, and a fixing metal fitting fixed to the floor surface. a cable holding bolt attached to the cable built-in part at a position where a cable protection tube of the cable stored in the cable built-in part whose surface is fixed via a fixing member is crimped between the cable protection tube and the floor surface; The above-mentioned fixing metal fitting fixed to the above-mentioned floor surface can be built in, and a cable through hole is provided in the ceiling part of the upper surface at a position corresponding to the above-mentioned cable pull-out hole, and the above-mentioned ceiling part is fixed to the bottom surface of the above-mentioned fixing metal fitting, and the side wall is formed into a conical slope, and the length of the notch in the center of the H-shaped carpet is longer than the length of the cable built-in part,
and the central notch is cut in the direction of forming the U-shaped groove of the cable built-in part of the fixing fitting fixed to the floor surface, and the end face part of the carpet cut by the central notch sandwiches the cable built-in part. H-shaped notches formed in the carpet are formed so as to face each other on both outer sides.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The undercarpet cable lead-out portion of the present invention will be explained below using an embodiment with reference to FIGS. 1 to 5. Figures 1 and 2 are perspective views of the fixing fittings and cover fixed on the floor at the cable pull-out position, respectively; Figure 3 is a plan view of the H-shaped notch cut into the carpet at the cable pull-out position; Fourth
FIG. 5 is a sectional view of the drawn-out position. In the figure, reference numeral 1 denotes a fixing fitting, and the fixing fitting 1 includes a cable built-in part 16 having a U-shaped cross section and
The U-shaped opening end has a floor fixing surface 17 formed parallel to the bottom surface 16a of the U-shaped groove and fixed to the floor surface 14, and a cable pull-out hole 2 opened in the bottom surface 16a.

As shown in FIGS. 4 and 5, the cable built-in portion 16 of the fixture 1 is fixed to the floor surface 14 by the floor fixing nail 15 of the fixing member.
Cable restraint bolt holes 3, 4, and 5 into which cable restraint bolts (not shown) for fixing the cable protection tube 12 of the cable 11 housed in the U-shaped groove are inserted are arranged in a direction perpendicular to the direction in which the U-shaped groove is formed. It is opened to The cable holding bolt hole 4 is opened at a position slightly higher than the floor surface 14. Cable-holding bolt holes 3 and 5 are cable-protecting holes that are guided on the upper surface of the cable-holding bolt that is inserted into the cable-holding bolt hole 4 in the longitudinal direction of the cable protection tube 12 at positions that sandwich the cable-holding bolt hole 4. An opening is provided at a position where the cable protection tube 12 can be crimped between the cable restraint bolt inserted in the upper part of the tube 12 and the floor surface 14. 6 is a hole for a floor fixing surface for fixing the floor fixing surface 17 with a floor fixing nail 15 as shown in FIG. Reference numerals 7 and 8 indicate cover fixing bolt screw holes for fixing the cover 9 to the upper surface of the bottom surface 16a of the cable built-in portion 16 with bolts 10, as shown in FIG.

As shown in FIG. 2, the cover 9 can house the fixing fitting 1 whose side wall is formed into a conical slope, and
A ceiling part is formed on the top surface of the fixing bracket 1 so that it can be attached, and the ceiling part has a cable pull-out hole 2 formed in the cable built-in part 16 and a cover fixing bolt screw hole 7.
8, the cable through hole 2a and the round holes 19, 19 are opened. Reference numeral 18 denotes an H-shaped notch in the carpet 13 where the cable 11 is placed in the pulled-out position. has been done. 13a
13b is a carpet main body, and 13b is a carpet rubber portion.

In order to pull out the cable 11 laid on the floor surface 14 on the lower surface of the carpet 13, an H-shaped notch 18 is cut into the carpet 13 as shown in FIG. Roll up the bent pieces 18b, 18b and make the floor surface 1
Fixing metal fittings 1 are fixed onto 4 with floor fixing nails 15. At this time, the direction in which the U-shaped groove is formed in the cable built-in part 16 is aligned with the direction of the notch 18a of the H-shaped notch part 18, and the cable 11 is placed in the cable built-in part 16.
Pull in the cable protection tube 12 and pull it out from the cable extraction hole 2. Then, as shown in FIG. 4, the cable protection tube 12 is guided to the top of the cable restraint bolt inserted into the cable restraint bolt hole 4, and the cable protection tube 12 is inserted into the cable restraint bolt holes 3 and 5 at the top of the cable protection tube 12. The cable protection tube 12 is pressed into contact with the floor surface 14 using the cable holding bolt, and the cable 11 is in the pulled-out position.
Attach so that it is fixed. Therefore, the bent pieces 18b, 18b separated by the notch 18a of the H-shaped notch 18 are diagonally connected to the cable built-in part 1 as shown in FIG.
They are opposed on both sides of 6. Then, attach the cover 9 to the top surface of the fixture 1 and attach the cable through hole 2.
Pull out the cable 2 together with the cable protection tube 12 from a, and attach the cover 9 to the fixing bracket 1 with the bolt 1.
Fix it with 0 and complete the work.

In this way, the undercarpet cable pull-out part of this embodiment has an H-shaped notch in the carpet at the position of the fixing bracket that is fixed to the floor surface at the cable pull-out position, and is separated by the notch in the center of the H-shaped notch. The end faces of the bent pieces were made to face each other on both outsides of the cable built-in part of the fixing bracket, and the cable protection tube of the cable at the pulled-out position was fixed in the cable built-in part, and the cable was pulled out and the cover was fixed on the top surface of the fixing bracket, so that the cable was fixed at the pulled-out position. In addition to preventing the cable from slipping and securely fixing it, there is no need to cut off a part of the carpet at the pull-out position as in the conventional case, and by simply making an H-shaped cut, the cable can be fixed securely. Even after changing the pull-out position, the H-shaped notch is left behind to maintain an orderly appearance.

As described above, the undercarpet cable pull-out portion of the present invention has the effect of preventing the cable from shifting its pull-out position and maintaining an orderly appearance even after the pull-out position of the pull-out hole formed in the carpet is changed. It has the following.
