Description

  The present invention relates to a wiring cover formed by a wiring opening formed on a top plate such as a desk or table and a duct having a substantially U-shaped cross section disposed on the lower surface thereof, and a wiring cover attached to the opening of the top plate. The present invention relates to a frame structure for supporting (also referred to as an opening lid).

  A wiring duct configured by providing a horizontally long or rectangular opening at the center of the top plate and providing a duct below the opening is known from Patent Documents 1 and 2, for example.

  Wiring ducts are prone to become long because a large amount of various wirings, their connected devices, relay devices, and the like have been accommodated in response to office conditions in which so-called OA has recently remarkably advanced. Therefore, a new problem is derived.

  In other words, if the opening of the wiring duct is left fully open, not only the internal wiring can be seen from the outside and the appearance does not look good, but also office supplies such as writing instruments used on the top plate are ducted. It is easy to become a hindrance to business operations due to falling inside. On the other hand, a rubber lid or a lid having a rubber edge is arranged with a small gap (a gap that allows one wiring to be inserted) between the opening and the wiring is taken out from the gap. There is a known method of introduction, but there is a problem that if the lid cannot be removed, large devices such as the above-mentioned connection devices (such as outlets and routers) cannot be taken in and out.

  Therefore, recently, a mounting-type lid that can be attached to and detached from the opening of the wiring duct as described above, that is, a wiring cover, or a removable opening and closing type in which an opening and closing support member such as a hinge is interposed in the opening. Many devices including the wiring cover have been proposed including the above-mentioned patent documents.

  However, conventional lids for wiring ducts, i.e., wiring covers, have a flat cover type mounting method and a hinge opening / closing method in which an opening / closing support member such as a hinge is interposed. Therefore, even if the design of the top board, desk, table, etc. is the same, the wiring covers of different installation methods are supported by support members having different structures. For this reason, there is a problem that support members having different structures or parts thereof must be prepared in advance.

In view of such points, Patent Documents 1 and 2 propose a cover for a wiring duct that can be deployed both in a mounting type and a hinge opening / closing type, but the wiring provided on the opening side of the top plate. The structure of the portion that supports the cover tends to be complicated, and therefore there is a problem that the opening / closing operation and the attaching / detaching operation of the cover must be complicated.
