Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of a desk for office use or financial business use.

[Problems that conventional technology and ideas try to solve]

Since it has been necessary to mechanize office work by placing office equipment such as microcomputers and word processors on desk tops, the specification and drawings of U.S. Patent No. 3,829,187 suggest that desk tops be supported by left and right cabinets. On the other hand, in the left and right longitudinal hollow frame that connects the rear surfaces of the left and right cabinets and the lower surface of the desk top plate,
Some have holes for the wiring cords to pass through from left to right.

Similarly, Japanese Utility Model Application No. 60-105426 discloses that a wiring tray is provided within a frame that connects the rear ends of both the left and right plate-like legs below the desk top.

According to these configurations, the rigidity of the desk is increased by the left and right longitudinal frames. However, connecting the left and right legs with such a frame tends to increase the weight of the desk.

In addition, these frames are located at the rear end of the desk (the side opposite to the side where people sit on the chair), so they are not suitable for desks such as counters used for dealing with customers in offices or financial services such as banks. In order to prevent the lower part of the desk from being seen from the rear side of the desk from the visitor's line of sight, it is necessary to cover the rear surface of the frame board with a rear curtain board to improve the aesthetic appearance of the desk. In this case, if the rear curtain plate is configured to be openable and closable so that the wiring work can be performed from the rear side of the desk, there is a risk that the wiring will be tampered with on the visitor side (the rear side of the desk).

The present invention solves the above-mentioned disadvantages of the conventional technology,
The purpose of the present invention is to provide a desk that is light in weight, yet increases the rigidity of the desk, facilitates wiring work, and improves the safety of wired wiring cords. It is.

[Means to solve the problem]

Therefore, in the present invention, the left and right legs of the desk are formed into a U-shape when viewed from the side, including a support section, arms and legs extending from the upper and lower ends toward the front of the desk. In a desk where the body support is located midway in the longitudinal direction of the desk top and the desk top is fixed to the upper surface of the arm, an upper reinforcing beam is used between the arms of both the left and right legs.
In addition, the legs are connected and fixed by lower reinforcing beams, and between the upper and lower reinforcing beams, the ends of a plurality of left and right long wiring trays are fixed to the front surfaces of the pillars of the left and right legs, and the ends of the left and right long wiring trays are fixed between the upper and lower reinforcement beams. A rear curtain plate that covers the rear side is fixed to the rear surface of the column of each of the legs, and an end panel is detachably fixed to the outer surface of each leg, while a front panel that covers the front of the wiring tray is fixed to the rear surface of the support column of each of the legs. It is detachably attached to the reinforcing beam.

[Functions and effects of the invention]

According to this configuration of the present invention, between the pair of left and right legs formed in a U-shape in side view, which includes a support and arms and legs extending from the upper and lower ends of the support toward the front of the desk, The upper and lower reinforcing beams are used to connect and fix the legs, and the front surfaces of the leg supports that are sandwiched between the upper and lower reinforcing beams are connected using a plurality of left and right long wiring trays. With the legs, a strong framework structure is completed, and only a small number of parts are required, which has the effect of increasing the rigidity of the desk and reducing the weight of the desk.

In addition, the pair of left and right legs, which are U-shaped in side view, have their support portions located midway in the front-rear direction of the desk top, and cover the rear surfaces of the support columns of the pair of left and right legs with a rear curtain plate.
In addition, since the end panel covering from the outside is fixed across the outer end surfaces of both the left and right legs and the left and right outer end surfaces of the desk top plate, it can also be used as a counter desk.
The lower and front parts of the desk can be completely hidden from the visitor's side, resulting in the effect of not spoiling the aesthetic appearance.

Moreover, since the rear curtain plate is fixed to the support column, there is no possibility that the wiring cord part in the wiring tray located in front of it will be tampered with from the rear side of the desk.

The front panel that covers the front of the wiring tray is detachably attached to the upper and lower reinforcing beams, so wiring work to each wiring tray is easy, and the front panel that is attached to the legs The space between the desk panel and the rear curtain board and the wiring tray placed in that space are all hidden, resulting in the effect that the aesthetics of the desk will not be spoiled.
