Description

[Detailed Description of the Invention] The present invention relates to an improvement of an office desk.

Office desks often have corded devices such as telephones on them, so the cords hang down from the top and are scattered on the floor, deteriorating the appearance, causing people to trip over them, and making it difficult to clean. Because the cord protrudes from the back of the top plate, it is necessary to place the backs of the top plates close to each other.
There was an inconvenience in that the back of the top plate could not be brought into close contact with the wall surface. In particular, in recent years, in order to improve office efficiency, terminals for various online systems, office computers, word processors, and other so-called office equipment have become more common on desks. As a result, the above-mentioned inconvenience was further exacerbated.

Regarding this problem, the Jikko Kosho 55 as a prior art
- In Publication No. 30330, the rear curtain plate installed on the back of the desk is configured in a hollow shape with a front panel and a back panel, and the front panel is configured to be detachable, so that the hollow space between the two panels is On the other hand, by forming a notch in the edge near the back of the top plate and inserting the cord through this notch, the cord can be placed inside the back of the top plate. I try to let them do it.

However, in the case of the prior art, the entire rear curtain board is formed into a hollow shape with a pair of front and back panels, and the cord is formed in the hollow part, so it is troublesome to have to remove the front panel one by one when storing the cord. In addition, since the front panel must be configured to be detachable, the structure of the rear curtain plate becomes complicated, and processing is labor-intensive, resulting in an increase in manufacturing costs.

Additionally, when a notch is formed in the desk top plate for the cord to pass through, a protective frame is removably attached to the opening of the notch to prevent the cord from protruding from the notch. In the case of the above-mentioned publication, as a mounting means, a frame is fixed to the inner surface of the notch, vertically elongated engagement grooves are formed on the left and right inner surfaces of the frame, and the left and right engagement grooves of the protective frame are formed on the left and right inner surfaces of the frame. The protrusions protruding from both sides are fitted. However, in the case of desks on which office automation equipment is placed, the notches are formed to be quite horizontally long so that many cords can be inserted through them, and the length of the protective frame also increases accordingly. The method of fitting the protective frame with the groove has the disadvantage that it cannot be firmly engaged and is likely to come off easily.Furthermore, if the protective frame is simply made longer, the material cost will increase in proportion to the length. Become.

In this case, the prior art of the protective frame mounting means suitable for the case where the notch groove is formed horizontally and horizontally is as follows.
There is Japanese Utility Model Application Publication No. 55-49602, which states that a horizontally long flat mounting plate is fixed to the bottom of the notch groove, and a cover that covers the entire notch groove is attached to and detached from the mounting plate. In addition to allowing the cover to be attached freely, a notch for inserting the cord is formed in the front part of the cover. However, in this case,
Since it is necessary to form an engaging protrusion on the back of the mounting plate for engaging the cover, it is not possible to form a cord insertion hole across the entire left and right sides of the notch groove, so it is difficult to make the notch groove wide. There was also a problem that many cords could not be inserted.

The present invention aims to solve these problems.

Therefore, in the present invention, the top plate is supported by the left and right legs, and a rear curtain plate is disposed between the rear ends of the left and right legs, approximately parallel to the back surface of the top plate. In the desk, a vertical gap of an appropriate size is formed between the upper surface of the rear curtain plate and the lower surface of the top plate, and a rear surface is formed by the rear curtain plate near the lower surface of the top plate. A cord storage section with a top opening is formed, and one or both of the left and right ends of the cord storage section are opened downward, while the left and right longitudinal ends of the cord storage section are formed on the rear edge of the top plate. A cutout groove is formed that vertically communicates with the cutout groove, and an edge frame body having a U-shape in plan view that opens rearward is fixed in the cutout groove. A protection frame is provided on both left and right sides of the edge frame by protruding engaging portions having a U-shaped cross section at appropriate lengths and forming a U-shape in cross section with a downward opening. The left and right ends of the protective frame are disposed at a position closer to the open part between the surfaces, and the left and right ends of the protective frame are removably fitted into the engaging part from above, and the lower parts of the left and right sides of the protective frame In this embodiment, a removable locking portion is provided protruding from the engaging portion.

With this structure, the cutout groove formed in the top plate is located above the storage part provided inside the desk, so that the cutout groove and the cord storage part communicate directly in the vertical direction, so that the cord can be easily stored. It is possible to insert the cord into the cord storage part by simply hanging it downward from the cutout groove, and since a part of the cord storage part is facing downward, the cord can be inserted to the required length through this downward opening. It can be pulled out to the outside,
Moreover, in that case, since a gap is formed between the rear curtain plate and the top plate, the cord can be pulled into the cord storage part or pulled out to the outside using this gap.

Therefore, according to the present invention, the OA placed on the top plate
When disposing of a large number of cords from devices, etc. so that they do not protrude outside the desk, there is no need to remove the rear curtain board one by one, so the cords can be disposed of quickly, making it easier to install office equipment, telephones, etc. This allows you to quickly change the desk layout, etc. Moreover, since the cord storage section is formed by sharing a part of the rear curtain plate, and the rear curtain plate does not need to be configured to be detachable while remaining fixed to the legs, the overall structure of the desk can be changed. It is extremely simple, has the function of reliably preventing excess cords from protruding outside, and can be manufactured at low cost.

In addition, the protective frame to be attached to the notch groove has a U-shaped cross section with a downward opening, so its rigidity is strengthened even when the wall thickness is reduced, and even when the length is increased. It is possible to reduce the weight and save material costs, and since it can be fitted into the engaging part and still be firmly fixed by engaging the locking part, it prevents it from accidentally coming off. There are things you can do to protect your code. Moreover, since the protective frame can be formed in a straight line, it can be arranged in a straight line along the back of the top plate, and the entire left and right direction of the notch can be used as a cord storage area, and the appearance It can also be used to make it more difficult to use.

Furthermore, the engaging part of the frame installed in the notch groove,
Since the cross section is formed in a U-shape with a downward opening, the frame body can be screwed to the top plate at this engagement part, and the screw heads can be prevented from being exposed on the side of the notch groove, so the appearance can be improved. can be further improved.

Next, an embodiment of the present invention will be described based on the drawings. 1 supports a top plate 2 with left and right legs 3, 3, and has a top plate 2 between the rear parts of the left and right legs 3, 3.
This is an office desk comprising a rear curtain plate 4 arranged approximately parallel to the back surface of the office desk 1. They are arranged so that gaps are formed at appropriate intervals vertically between them.
