[Prior art]
Conventionally, cabinets are for storing documents and files, so it is not supposed that electronic and electric devices are stored or mounted on a top plate and used. There was no structure for it.
[0003]
Therefore, the present applicant has proposed a cabinet provided with a structure for wiring and housing cords on the back side (see Patent Documents 1 and 2). That is, in Patent Literature 1, an auxiliary top plate is detachably or rotatably disposed with respect to a support bracket provided at an upper end portion of a rear surface of a cabinet, and the auxiliary top plate and a top surface of the cabinet are connected to each other. While making the same plane, the side cover plate was detachably mounted on the back side of the cabinet via a bracket, and the rear part of the cabinet surrounded by the auxiliary top plate and the side cover plate was configured as a wiring space. A wiring structure in a cabinet is disclosed. Further, in Patent Document 2, a frame-shaped wiring duct body formed so that a wiring passage is communicated over four circumferential sides is connected to the back surface of a main body case of furniture such as a cabinet, and the back surface of the wiring duct body is connected. It is connected so as to cover with a panel device, and furthermore, the left and right side surfaces and the upper surface of the wiring duct body are respectively covered with detachable cover plates, and the surfaces of the respective cover plates, and the side and top surfaces of the main body case of the furniture. There is disclosed a wiring structure in furniture configured to be substantially flush.
[0004]
However, since the thing of patent document 1 presupposes the usage form which arranges a back side closely on a wall surface or a partition panel, a back cover does not exist on the back side, and therefore, when it arranges in an island mode, the back is exposed. It is virtually impossible to use. Further, the thing of patent document 2 attaches the square frame-shaped duct main body which has the duct part which consists of the concave groove opened to the outer periphery to the back of furniture, such as a cabinet, and the upper surface cover which can attach and detach the duct part. Because the vertical cover covers the side and top surfaces of the main unit case of the furniture so that they are almost flush, a duct body that is approximately the same size as the front shape of the furniture is required, which increases the size and weight. The weight is also heavy, so that it is difficult to handle and the parts cost increases.
