Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of an office desk.

[Background of the idea]

In recent years, with the advancement of office automation, so-called OA equipment such as computers and word processors are increasingly placed on desks, but these OA equipment have long cords and intermediate equipment such as repeaters. As more and more desks are connected, these cords and intermediate devices protrude outside the desk, resulting in an increased problem of unsightly appearance and tripping hazards for people.

[Conventional technology]

Conventionally, to solve this problem, a shelf board was installed between the inner surfaces of the left and right legs, and excess cords and intermediate equipment were stored and placed on this shelf board, or, alternatively, in actual implementation As disclosed in Publication No. 56-158926, a cord locking device is fixed to the inner surface of the rear curtain plate that blocks the rear part of the desk, and the excess cord is wrapped around this cord locking device. There is.

[Problem that the invention attempts to solve]

However, although the former method of mounting a shelf board between the left and right legs has the advantage of increasing the amount of storage for cords and intermediate equipment, it also has the problem of deteriorating the appearance because the shelf is visible from the outside. , in the latter case where the cord storage means is formed on the inner surface of the rear curtain plate,
Even if the deterioration of the appearance could be avoided, there were problems in that it became troublesome to store cords, etc., and it was not possible to increase the amount of cords, etc. stored.

In other words, if a storing means for cords, etc. is formed on the inner surface of the curtain board as in the invention of the above-mentioned Utility Model Application Publication No. 56-158926, when storing cords, etc., a person must first fix the curtain board to the desk. Storing the cords, etc. is very troublesome because you have to crawl inside the desk and pull the cords together to store them, and the load of the cords, etc. acts on the curtain plate, so many cords and intermediate devices are locked. This would cause the curtain plate to bend and become deformed, and there was a limit to the amount of cords etc. that could be stored.

The present invention solves the above-mentioned problems of the prior art by devising the form of the rear curtain plate when processing the cords of OA equipment used on desks.

[Means for solving the problem]

In order to solve this problem, the present invention provides a desk in which a top plate is disposed between the upper ends of the left and right legs, and a rear curtain plate is disposed between the rear ends of the left and right legs. The curtain board is provided with a frame body having a rectangular shape in front view, in which the upper and lower sides of the left and right pillar members are connected by a cross beam member, a back cover detachably attached to the back of the frame, and a back cover detachably attached to the front of the frame. The front cover is formed into a hollow shape, and the left and right ends of the frame are connected to the rear parts of the left and right legs, while the inner surfaces of the left and right pillar members of the frame are formed from the front and rear widths of the pillar members. A bracket with a small front and rear width is installed sideways,
A tray capable of storing intermediate equipment such as cords and OA equipment is removably attached to the bracket, and the left and right length of the tray is made smaller than the interval between the left and right column members. A vertically communicating wiring path is formed between the side end surface of the column member and the inner surface of the column member.

By facing the cord insertion passages 34 formed on the left and right sides of the cord insertion passage 18, when pulling out a large number of cords from the cord insertion passage 34, it is possible to pull out an appropriate number of cords at a time, or when the cords are long. In such cases, the cord can be wrapped around the left and right latch pieces 40 to prevent the cord from becoming tangled.

The front cover 41 is formed into a shallow box shape by folding back its side edges, and is detachably attached to the frame 17 by the following means.

That is, as shown in FIG. 11, engagement holes 45 are formed in the lower folded piece of the front cover 41 at appropriate intervals on the left and right, and the engagement holes 45 are formed in the front surface of the lower cross beam member 14 in the main body 17. The upper part of the front cover 41 is provided with a substantially dogleg-shaped locking claw 48 projecting downward, and this locking claw 48 is
It is inserted and locked into the lower folded piece 47 of the upper cross beam member 15 located on the front side. In this case, the lower folded piece 47 of the upper cross beam member 15 is provided with a hole 46 into which the bent portion of the locking pawl 48 fits, so that the locking pawl 48 is elastically engaged. There is.

As described above, the rear curtain plate 3 is formed into a hollow shape,

This means that it is possible to reliably prevent this from happening.

In this case, since the tray 22 is mounted between the left and right pillar members 13 of the frame 17, the back cover 18 and the front cover 41 can be attached and detached while the cords, etc. are stored in the tray 22. This makes storage work extremely easy.
Further, since the trays 22 are mounted on the frame 17, a large number of trays 22 can be provided, and the back cover 1
8 and front cover 41 without causing deformation.
The amount of storage for cords and intermediate equipment can be increased, and since the tray 22 is removable, it is extremely easy to take equipment into and out of the desk.

Furthermore, the wiring passage 25 is formed by making the front-to-back width of the bracket 20 smaller than the front-to-back width of the column member 13, and by making the left-right length of the tray 22 smaller than the interval between the left and right column members. , wiring passage 2 without drilling holes in the member, etc.
5 can be formed.

Note that the assembly type desk in the example is assembled in the following steps.

That is, when the longitudinally elongated protruding strips 11 at the rear of the inner surfaces of the left and right leg bodies 2 are fitted into the dovetail grooves 12 formed at both left and right ends of the frame body 17 in the rear curtain plate 3, the dovetail grooves 1
2 until the upper end of the vertically elongated protruding strip 11 comes into contact with the lower surface of the abutting plate 19 at the upper end, and the rear curtain plate 3 does not descend any further, and both the left and right legs 2 and the rear curtain plate 3 are separated from each other in plan view. Strongly connected in a U-shape.

Next, insert the four locking tools 5 into the locking grooves 4 of the left and right legs 2, and among the locking tools 5, the one in the front position slides forward, and the one in the rear position slides backward. , each locking tool 5 is attached to the leg body 2.
Then, by dropping the top plate 1 from above, the left and right legs 2 and the top plate 1 are connected. In this case, by fitting the positioning protrusion 42 projecting upward on the main body 5' of the rear locking tool 5 into the positioning hole 43 formed in the lower horizontal piece 9 of the top plate 1, the top plate 1 can be moved back and forth. It is made so that it cannot be shifted in either the left or right direction.

When wiring and repairing cords, etc. after assembling the desk, if the back of the desk is open, it is sufficient to remove the back cover 18 and store from the outside.Also, if the desk is installed facing each other, In such a case, the front cover 41 may be removed and the storage operation may be carried out from inside the desk.

[Functions and effects of the idea]

The present invention is constructed as described above, and cords for OA equipment used on a desk can be pulled out onto the desk through the wiring passage in the hollow part of the rear curtain plate, and excess cords and intermediate equipment can be removed. The equipment can be stored in a tray mounted inside the hollow part of the rear curtain plate, so that cords, etc., are exposed to the outside, deteriorating the appearance, and preventing people from tripping over cords, etc. that are dripping onto the floor. This means that problems can be reliably prevented. The features described in the claims for utility model registration provide the following effects.

The tray for storing cords, etc. is mounted between the left and right pillar members of the frame, so the back cover and front cover can be attached and removed while the cords, etc. are stored in the tray. Work can be done extremely easily.

Since the trays are mounted on the frame, a large number of trays can be provided, and the storage capacity of cords and intermediate devices can be increased without causing deformation of the back cover or front cover.

Since the tray is removable, it is extremely easy to take equipment in and out of the desk from the back of the desk.

When forming the wiring passage in the hollow part of the rear curtain plate, the front and rear width of the bracket should be smaller than the front and rear width of the column members, and the left and right length of the tray should be smaller than the interval between the left and right column members. Since the wiring path is formed by the above method, it is possible to prevent the number of processing steps for the member from increasing in order to form the wiring path.
