The present invention has been made in view of such circumstances,
An object of the present invention is to provide a round-shaped wire take-out tool for a floor wiring device having a simple structure, which is capable of solving the problems all at once while taking advantage of the above-mentioned conventional device.

B. Configuration of the Invention (1) Means for Solving the Problems To achieve the above object, the present invention covers a duct main body having an open upper surface provided on a floor covered with a finishing material, and an open upper surface of the duct main body. , From the inside of the duct body of the floor wiring device having a duct cover flush with the floor, for taking out the round cable through the outlet formed in the duct lid, in the round wiring device for floor wiring device, An edge frame body having an opening corresponding to the outlet and mounted on the upper surface of the peripheral edge of the outlet of the duct lid, and at least one through hole recess for closing the opening. A lid body to be placed on the edge frame body, and a first body whose screw is inserted into the duct lid through the edge frame body to fix the edge frame body to the duct lid and whose head is covered with the lid body. The lid body is screwed into the edge frame body through a screw member and the lid body. And a second screw member whose head is exposed from the upper surface of the lid body, and the lid bodies are arranged in parallel with each other so as to traverse the recess for passage hole drilling. A pair of lid halves individually secured to the upper surface of the edge frame by a second screw member,
Each of the lid halves is integrally provided with a brim portion for sandwiching an end edge of the finishing material between the lid lid and the duct lid so as to protrude outward from the edge frame body.

(2) Operation According to the above configuration, in the state in which the duct lid is removed from the duct main body while the lid body divided into two is screwed to the duct lid, the passage hole drilling concave portion is punched to form the passage hole. Since the drilling work can be performed, the drilling work is very simple, and it is possible to avoid chips and the like from entering the duct body and damaging the wiring in the duct body during the drilling.

Further, since the edge frame body is mounted on the peripheral edge portion of the outlet of the duct lid and is fixed to the peripheral edge portion of the outlet by the first screw member, the upper surface of the peripheral edge portion of the duct lid can be formed by the edge frame body.

Moreover, even after the edge frame is set on the duct lid, the edge frame can be easily separated from the duct lid. Therefore, if the edge frame is damaged, only the edge frame can be easily replaced. It is possible. Moreover, since the head portion of the first screw member for fixing the edge frame body to the duct lid is covered with the lid body and is not exposed on the upper surface of the lid body, the appearance of the lid body may not be deteriorated. There is also no risk of accidentally loosening the first screw member when loosening the second screw member and opening the lid.

Furthermore, even if the cutout work on the finish material is performed slightly inaccurately, the cutout edge of the finish material can be covered with the flange part of the lid, so the cutout work on the finish material can be performed somewhat rough. And Further, when the edge of the finishing material is sandwiched between the collar portion and the duct lid, the lid member is placed on the edge frame body while simply holding the edge of the finishing material with the collar portion from above. Since only the screw member needs to be tightened, there is no risk that the edge of the finishing material will be wound around the collar and scratched or wrinkled, and the flange and duct lid for the edge of the finishing material at that time The sandwiching interval can be constantly regulated by an edge frame body that is placed on the duct lid and the lid body is placed on the upper surface.

Effect of the Invention As described above, according to the present invention, the through hole drilling recess provided in the lid body is provided inside and outside the lid body in a state before the through hole is drilled therein. Since it does not communicate with each other, there is no risk that dust or the like will infiltrate into the duct body. Moreover, in the state in which the duct lid is removed from the duct main body while the two divided lids are screwed to the duct lid, it is possible to perform the work of forming the through hole by punching the recess, so that the drilling work is very successful. Not only is it simple, but it is possible to reliably prevent chips and the like from entering the duct main body and damaging the wiring inside the duct main body when drilling.

In addition, since the edge frame body is placed on the outlet opening peripheral portion of the duct lid and is fixed to the outlet opening peripheral portion by the first screw member, the upper surface of the outlet edge peripheral portion of the duct lid is fixed by the edge frame body. It can be covered well, and it is not necessary to finish the upper surface of the peripheral portion in a particularly careful manner, so that the duct lid can be easily processed, and even after the edge frame body is set on the duct lid, Since the edge frame can be easily separated from the duct lid, if the edge frame is damaged, etc., it is possible to easily replace only the edge frame and not the entire duct lid. Can contribute to the saving of. Moreover, the first for fixing the edge frame body to the duct lid.
Since the head of the screw member is covered with the lid and is not exposed on the upper surface of the lid, the appearance of the lid is good, and the second screw member is loosened to open the lid. In that case, there is no risk of accidentally loosening the first screw member.

Further, since a pair of lid halves constituting the lid body is integrally provided with a collar portion for sandwiching the end edge of the finishing material between the duct lid and the edge frame body, the brim portion is integrally provided. Even if the notch work is performed slightly inaccurately, the notch edge can be covered with the flange portion, so that the notch work of the finishing material can be performed somewhat rough, and the notch work is easy and efficient. You can When sandwiching the finishing material edge between the collar portion and the duct lid, the lid member is placed on the edge frame body while simply holding the finishing material edge from above with the collar portion. Since it is only necessary to tighten the 2 screw members, there is no risk that the edge of the finishing material will be wound around the collar and scratched or wrinkled, and the flange and duct lid for the edge of the finishing material at that time Since the holding interval can be constantly regulated by the edge frame body that is placed on the duct lid and the lid body is placed on the upper surface, the edge of the finishing material can always be properly pinched. As described above, the edge frame body can be used both as the replaceable edging means for the outlet and as the spacer means for uniformly controlling the holding interval with respect to the edge of the finishing material, which contributes to the simplification of the structure of the apparatus. it can.
