Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a desk unit capable of forming desks of different forms such as an office desk and a learning desk by combining common members.

Conventional technology and its problems As a single-sleeve desk, which is a basic form of an office desk or a study desk, a one provided with a curtain plate that shuts off the underside of the desk is widely used. In such a desk with a curtain plate, a plate-like body, that is, a leg plate is generally used as a leg body so that the underside of the desk can be blocked from the side, and the curtain plate is provided between the leg plate and the sleeve box. It is stretched with screws. Further, since the plate-like portion of the leg plate cannot be screwed directly to the top plate from below, it is usual to provide a mounting stay at the upper end for projecting toward the center of the desk for screwing.

By the way, in order to reduce costs and standardize work by mass production in desk production, it is very convenient if desks having different shapes can be produced by combining common members. Also, even in offices, if the desk form can be changed by changing the constituent members in response to changes in work content, personnel composition, changes in the interior layout, etc., it is possible to reduce the labor, time, cost, etc. involved in replacing the desk. There is an advantage.

However, even if an attempt is made to share the above-mentioned constituent members of a single-sleeve desk with a curtain plate into a member of a flat desk without a sleeve box or a sleeve box, the width of the curtain plate is too long for both sleeve desks. It cannot be used as a common member because it is too short for a flat desk. Furthermore,
The leg plate and sleeve box require screw holes for mounting the curtain plate on the opposite sides, and if the positions of both are reversed, the curtain plate cannot be attached.To cope with this, there are screw holes on both left and right sides of both. In case of providing the above, since the unused screw holes are exposed on both sides of the desk, it is difficult to change the form of the right sleeve type and the left sleeve type by the same member.

Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances, and by combining all common members, as a desk with a curtain plate having a good appearance, a right sleeve type and a left sleeve type single-sleeve desk, double-sleeve desk By providing a desk unit that can easily configure any of the flat desks, productivity in manufacturing desks can be improved, costs can be reduced, work standardization can be realized, and the user can change the desk form as necessary. The purpose is to make possible.

That is, in order to achieve the above object, the desk unit of the present invention comprises a top plate, a curtain plate screwed to the rear edge thereof, a leg plate and a sleeve box screwed to the top plate and the curtain plate, The curtain plate is set to have a width almost equal to that of the top plate, and the leg plate and the sleeve box mounting portions are respectively formed on the right and left sides of the top plate. Holes are formed at two positions on the left and right sides, and are fixed to the upper end surface of the leg plate in a laterally protruding manner, and have a top plate mounting stay that can be reversed in the lateral direction. Is.

Action Since the mounting parts of the leg plate and the sleeve box are formed on the left and right sides of the top plate respectively, by selecting the combination of the leg plate and the sleeve box that support the top plate, the right sleeve type and the left sleeve type can be selected. Sleeve desk,
Both desks and desks can be configured. Since the curtain board is set to the left and right width almost equal to the top board,
It is arranged so as to cover the entire rear side of the desk regardless of the above-mentioned desk form, and can be screwed to the leg plate and the rear end surface of the sleeve box at both end portions thereof. However, the rear end face of the sleeve box needs to be provided with screw holes for attaching the curtain plate to the left and right sides in order to correspond to changes in the left and right arrangement positions of the sleeve box. In both the left and right sleeves, they are hidden behind the curtain. on the other hand,
