DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring duct in which the inside of a duct body is separated into a wiring groove for high current and a wiring groove for low current, and more specifically, is attached vertically along a leg of a table or desk. The present invention relates to a wiring duct.

[0002]

2. Description of the Related Art It is conventionally known to provide a table or desk with a wiring duct. For example, a wiring duct is formed in which a wiring duct is formed in a horizontal direction along a rear edge of a top plate, and the inside of a leg is used as a vertical duct for wiring.

[0003] Generally, as a wiring duct, a structure in which the inside of the duct body is divided into a high-current wiring groove and a low-current wiring groove is known. Some of the provided horizontal ducts for wiring separate such strong and weak electric wires, but few of the vertical ducts for wiring provided on the legs separate the strong and weak electric wires. The reason for this is that there is little need to start up and wire along the legs from the same floor at the same location because the high-voltage power lines such as power lines and the low-voltage lines such as telephone lines and LAN cables are drawn at different positions. It is because. Conversely, once wired from the floor to a table or desk, if it is wired across an adjacent table or desk, it is common practice to wire the heavy electrical wires and the weak electrical wires together using a horizontal wiring duct. Therefore, it is necessary to separate such strong and weak electric wires in the horizontal duct for wiring.

[0004] When wiring to the legs of a table or desk, there is a structure in which a high-voltage electric wire is wired inside the legs and a low-voltage electric wire is wired to a vertical duct for wiring mounted along the outer surface of the legs. However, there has not been provided any device capable of separately arranging strong and weak electric wires in the same vertical duct for wiring. The same can be said of the wiring duct for the partition panel. In the case of ordinary wiring ducts, after wiring wires in the wiring grooves of the duct main body, those with a structure that covers the opening by fitting a cover plate created separately are required to work on new wiring or add new wiring. Wiring work is troublesome, and in the case of a structure in which the cover plate is hinged to the duct main body, the cover plate may interfere with the wiring work.

[0005]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is intended to solve the problem by separately wiring a high-power wire such as a power line and a low-power wire such as a telephone line or a LAN cable. In addition, it is possible to provide a wiring duct suitable for wiring along the legs of a table or a desk, in which the wiring work can be performed very easily while the wires during the wiring work are stable. is there.

[0006]

The partition plate is raised from the mounting plate to separate the inside of the duct body into a wiring groove for strong electricity and a wiring groove for weak electricity, and the cover plate can be opened and closed freely via hinges along the edges of both side plates of the duct body In addition, a wiring duct is formed in which locking pieces are provided on both sides of the top of the partition plate, and locking claws are formed at free ends of both cover plates to be engaged with the locking pieces.

[0007] A first stop edge having a substantially L-shaped cross section is formed inside the ends of both side plates of the duct body, and a second stop edge having a substantially L-shaped cross section is formed on both sides of the end of the partition plate. The cover plate is formed and stably holds the electric wire arranged in the wiring groove, and when the cover plate is closed, the back surface of the cover plate is stopped by the ends of the first stop edge and the second stop edge. What can be done
This is preferable because the electric wires during the wiring work are stabilized and the closed state of the cover plate is stabilized.

Further, it is more preferable that the duct body and the cover plate are formed of a hard resin material, the hinge portion is formed of a soft resin material, and these are integrally formed by two-color extrusion.

The wiring duct is attached vertically along a leg of a table or a desk, and a two-part leg cover is detachably attached around a lower end of the leg, and the leg cover is used to attach the wiring duct. That is, the outer surface of the cover plate located at the lower end of the duct is stopped and cannot be opened.
