Description

[Detailed description of the invention] [Field of industrial application] The present invention is a desk system that makes it easy to wire a cord to the back of each desk when multiple desks are arranged side by side. This invention relates to the structure of a wiring cord insertion device on the rear side.

[Conventional technology and its problems]

In recent offices, office equipment such as small computers and word processors are often placed on desks. In this case, when multiple desks are arranged side by side, the
As a prior art for inserting wiring cords for OA equipment, telephones, etc., for example, Japanese Utility Model Publication No. 61-30507 discloses a method in which a rear curtain plate at the rear end of a desk is detachably separated into an inner panel and an outer panel. , the inner panel is connected between the rear ends of the legs on both the left and right sides of the desk, and the inner panel is equipped with a plurality of left and right longitudinal groove plates for receiving wiring cords, spaced apart from each other vertically, and the left and right sides of the outer panel are A plurality of cord entry ports are drilled in the upper and lower midpoints of both sides so as to communicate with each other in correspondence with the height positions of each of the groove plates, while left and right longitudinal drawer ports are drilled in the upper and lower surfaces of the outer panel, respectively. However, a configuration is disclosed in which a gap is formed between the upper surface of the outer panel and the lower surface of the rear end of the desk top plate.

According to this configuration, when the inner panel and the outer panel are assembled, the upper and lower corners of the left and right sides of the outer panel protrude so as to come into contact with the inner panel, so that the upper surface of the outer panel and the desk point In order to take out the wiring cord from the gap formed between the bottom surface of the rear end of the board, or to place the wiring cord on the groove board inside the inner panel, it is necessary to first remove the outer panel from the inner panel. However, there was a problem in that it took time and effort to attach and detach.

On the other hand, in Japanese Utility Model Application Publication No. 60-176630, a storage shelf for left and right long wiring cords is fixed between the inner surfaces of the left and right legs that support the desk top, and can be freely attached to and detached from the rear end surfaces of the left and right legs. Guide portions for inserting vertical and longitudinal wiring cords are formed on both left and right end surfaces of the rear curtain plate connected to the rear curtain plate, and each guide portion is closed with a flexible wiring cord insertion tool. A left and right longitudinal gap is formed between the end surface and the lower surface of the desk top plate, and a locking frame is attached to the upper end of the rear curtain plate so as to be movable up and down. Also in this prior art, in order to insert the wiring cord from the gap between the upper end surface of the rear curtain plate and the lower surface of the desk top plate to the storage shelf on the front side of the rear curtain plate and pass it through the guide parts on both the left and right sides, the above-mentioned locking is required. It is necessary to either rotate the frame to communicate with the guide, or remove the rear curtain plate.

The purpose of the present invention is to easily insert a wiring cord across both the left and right sides of a desk without having to attach and detach a large rear curtain plate as in the above-mentioned prior art. .

[Means for solving problems]

Therefore, the present invention connects the rear curtain plate of the desk to the legs attached to the left and right lower surfaces of the desk top plate and/or the inner surface of the sleeve cabinet, and connects the upper end of the rear curtain plate to the lower surface of the rear end of the desk top plate. A gap is formed between the left and right longitudinal wiring cords, and a wiring cord receiving gutter with both left and right ends open is provided on the front surface of the rear curtain plate, while a rear end of the leg body and/or sleeve cabinet is provided. A rear-opening notch is provided at the corner of the top surface and the bottom surface of the rear end of the desk top plate to communicate with the gap, and the inside of the notch can communicate approximately in a straight line with the receiving gutter. A cap body for closing the end of each gutter body is removably attached to the outer end surface of the leg body and/or sleeve cabinet.

[Functions and effects of the idea]

According to this configuration, the legs attached to the left and right lower surfaces of the desk top plate and the rear end upper corner portions of the sleeve cabinet are provided with rearward open cutouts so as to create a gap between them and the lower surface of the desk top plate. This combined with the fact that there is a left and right longitudinal gap formed between the top edge of the rear curtain plate and the bottom surface of the rear edge of the desk top plate, and these gaps are in communication with each other, makes it possible for the desk top plate to At the bottom of the rear end, a gap for wiring cords to be inserted is now connected to both the left and right sides of the desk top plate, allowing wiring cords to be easily routed to the front of the rear curtain plate without having to remove the rear curtain plate or outer panel as in the past. This has the effect of allowing the wiring cord to be inserted into the gutter.

In addition, since the gutter bodies provided in the notches in the legs and sleeve cabinets can communicate in a substantially straight line with the receiving gutter in the rear curtain plate, all you need to do is remove the cap bodies on the outer surfaces of the legs and/or sleeve cabinets. Therefore, it is possible to extremely easily guide the wiring cord placed on the receiving gutter in the rear curtain board to the outside of the desk in the lateral direction through the gutter body in the leg body and sleeve cabinet.

In particular, even if both ends of the wiring cord are connected for a long time, the wiring can be routed along the rear edge of desks installed on both the left and right side of the desk. This eliminates the need to route the wires around the cables or to route the wires under the lower ends of the legs and sleeve cabinets, and it also has the advantage that the required length of the wiring cord can be shortened.
