Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a wiring duct used for attaching an outlet to a building structure and wiring the outlet.

(Prior art) Conventionally, when installing an outlet on a building structure, such as a wall, the outlet is directly attached to the wall with screws, and then the connection between the outlet and the power line wired on the floor or ceiling is connected. Connections are made using electric wires that pass through a gutter that is attached to the wall with screws or double-sided adhesive tape, but in this case, due to the structure of the wiring using the gutter and the outlet, it must be connected to a wall far away from the corner of the room. It is installed in a relatively conspicuous position, and as a practical matter, it is not possible to match the inch reality of the line gutters and outlets, which vary widely.
Not only does this tendency become stronger as the number of wires and outlets increases, but as the number of wires increases, the line gutter becomes more likely to come off the wall, etc., and construction work becomes more difficult.

(Problems to be Solved by the Invention) An object of the present invention is to provide a wiring duct that can be easily installed even when the number of wiring lines and the number of electrical outlets increases without impairing the industrial design.

(Means for Solving the Problem) The present invention provides a duct main body of a wiring duct installed along a structure of a building so that its cross-sectional shape is a right triangular shape corresponding to the corner of the building. The receptacle mounting means is formed with an open oblique side of the duct body, and the receptacle is removably installed at any position in the longitudinal direction of the duct body, with the open surface serving as the insertion surface, and further, A wiring duct is provided with a wiring cover for removably attaching to the open surface of the duct body.

(Example) Next, the configuration of an example of the present invention will be described with reference to the drawings.

For installation along the corner of a building structure, for example, the cross section is formed into a right triangular shape, and the hypotenuse of the right triangle is open.The inside corner of the duct body 1, which forms a right angle, is covered with duct wood. The holding plate 3 for positioning the electric wire passing through the body 1, in this case, the 0Alfi coaxial cable 2 for connection between devices, is attached to a part of the corner forming the right angle. Main body 1
It is formed integrally with the duct body 1, and at each corner of both ends of the hypotenuse part of the right-angled triangle inside the duct body 1, a recess is formed for positioning the electric wire passing through a part of the corner, and a holding plate is attached for holding down the electric wire passing through the recess. For installation of outlet 9 described later, use and cover 1
2.14.14' For mounting, a presser protrusion 5' is formed to serve as reinforcement, and for mounting at a right angle, a presser plate 3 is attached to the protrusion 5, as well as an insertion groove 4. An insertion groove 8 for inserting a metal fitting 7 is formed for the mounting used when attaching the terminal block 6 to the duct body 1, and a mounting groove 8 for attaching the outlet 9 to the duct body 1 is formed on both edges of the open surface of the duct body 1. is a metal fitting 10, in this case, five slits S are arranged in the center to facilitate the center positioning of the outlet 9.The mounting is made of a metal fitting 10 with a slot 11 for insertion and no hole for covering the open surface of the duct body 1. A stepped part 15 is formed for attaching the cover 12 and a cover 14 with a hole that covers the outlet 9 except for the insertion part 13, and each cover 12.14 has a locking protrusion 16 protruding from the back surface of the duct. The insertion hole 1 of the hole-equipped cover 14.14' is attached to the duct body 1 while being locked to both edges of the open surface of the main body 1, and fits into the insertion part 13 of the outlet 9.
7.17-The inner circumferential edge is pressed into engagement with the outer circumferential edge of the insertion portion 13 of the outlet 9 to prevent the holed cover 14 from coming off the outlet 9, and the holed cover 14.
An engaging protrusion 18 is formed to maintain a constant gap between the inner peripheral edge of the insertion hole 17.17 of the socket 14' and the outer peripheral edge of the insertion part 13 of the outlet 9.

Straight joint duct 20 for connecting multiple sets of wiring ducts 19 of a fixed length or arbitrary length configured in this manner to each other in response to changes in wall surface length and wiring direction, etc. The joint duct 21 for direction conversion and the end cover 22 attached to the end face of the wiring duct 19 are each formed into a right triangular shape with no open surface, matching the cross-sectional shape of the wiring duct 19. Between 20.19 and 21 and between the wiring duct 19 and the end cover 22, positioning protrusions 23 protruding from each joint duct 20.21 and the end cover 22 fit into positioning grooves 24 formed in the wiring duct 19. and are positionally connected to each other.

Next, the operation of this embodiment will be explained.

First, arrange the duct body 1 along with the joint ducts 20 and 21 and the end cover 22 along the corner of the room where the outlet 9 is required, according to the dimensions of the room.
In this arrangement, attach the duct body 1 to the corner of the room using double-sided adhesive or screws (not shown).
When passing the coaxial cable 2 through each corner of a right triangle, for example, by inserting a metal holding plate 3 which also serves as a magnetic shield into the insertion groove 4 of each mounting number projection 5. The coaxial cable 2 can be easily wired, and when the power source is connected to the outlet 9 from external wiring, it can be installed with a metal fitting in the insertion groove 8 of the protrusion 5 at the connection position with the external wiring of the duct body 1. 7 is inserted, the installation involves attaching the terminal block 6 to the metal fitting 7, and
For installation, attach the wiring foil outlet 9 to the insertion groove 12 of the protrusion 5 with the metal fitting 10 attached, and attach each cover 12 to the stepped part 15 of the open surface of the duct body 1.
．． 14 and 14', the wiring duct 19 can be easily installed in the corner of the room.

(Effects of the Invention) The present invention provides a duct main body of a wiring duct installed along a structure of a building so that its cross-sectional shape is a right triangular shape corresponding to the corner of the building, and the hypotenuse of the right triangle is The plug-in socket is formed in an open state and is installed at any position in the longitudinal direction of the duct body in a removable manner using the open surface as the insertion surface. form,
Furthermore, the wiring duct is equipped with a wiring cover for removably attaching to the open surface of the duct body, and as a result, the present invention does not impair the inch-realistic design, and moreover, it is possible to cope with an increase in the number of wires and outlets. This also has the effect of making it possible to easily install the wiring duct with a sufficiently strong mark.
