[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk (table) and a joint used for its frame.

[0002]

2. Description of the Related Art Since desks are bulky, they are required to be easily packaged and transported.

Regarding this point, conventionally, it has been practiced to manufacture each of the rough components such as the top plate, the legs, or the curtain plate, and assemble them at the delivery destination.

For example, in Japanese Patent Laid-Open Publication No. 3-224507, in a desk in which the corners of a top plate having a rectangular shape in plan view are supported by rod-shaped legs, adjacent legs are detachably connected by horizontal members. In this publication, a top plate, legs, and horizontal members are separately packed, transported, and assembled at a delivery destination.

[0005]

By the way, there are various types of desks. For example, the top plate is not limited to a mere square shape, and various types such as an elliptical shape having an L shape in plan view are available. Also, the legs are rod-shaped, L-shaped in side view, U-shaped,
Alternatively, there is a wide plate shape.

In particular, in recent years, in order to improve the usability of OA equipment such as a personal computer and to cope with the change in work style represented by SOHO, desks with novel designs have been devised.

In such a situation that the appearance of the desk is diversified, it is preferable that the members are shared as much as possible to contribute to cost reduction and effective use of resources (of course, for each type such as a top plate). There are things that have to be made).

However, in most of the conventional desks including the invention of the above-mentioned publication, dedicated desks are constructed for each type of desk, and the commonality of the members and the ease of developing variations are not so great. Was not considered.

The present invention aims to improve such a situation.

[0010]

According to a first aspect of the present invention, there is provided a desk, a top plate, at least a pair of joints disposed below adjacent corner portions on at least a back side of the top plate, and adjacent joints. And a beam connecting the two. And
The side frame constituting the upper part of the leg or the side frame to which the sleeve cabinet is attached can be fastened to the joint with a fastener such as a screw, and the top plate is fixed to the side frame.

According to a second aspect of the present invention, a plurality of types of the legs according to the first aspect, such as a downward opening U-shape (gate shape), a side-view C-shape, or a wide plate shape, at least the upper end of which extends long. These legs are prepared, and a side frame is fixed to the upper ends of the legs in advance to form a unit, so that any type of legs can be fixed to the joint.

A third aspect of the present invention relates to a joint used for the frame structure of the desk according to the first or second aspect, wherein the joint is a base and side projections extending from the base in a direction orthogonal to each other in plan view. And a center protrusion that extends so as to bisect a portion sandwiched by both side protrusions in a plan view.

The side frames can overlap the both side protrusions, while the center protrusion is formed with two projecting portions extending in parallel with the side protrusions. The connecting beam can be fastened to the projecting portion.

[0014]

According to the present invention, the side frame forming the upper part of the leg and the side frame to which the sleeve cabinet is attached can be attached to the joint as a common component of the joint and the connecting beam in various desks. It is possible to configure top plate support structures of various variations.

That is, since it suffices for the leg to have a side frame at its upper end, it is possible to fix various types of legs such as rod-shaped ones and U-shaped ones in a side view to the joints. Not only can the sleeve cabinet be installed.

Further, since the adjacent joints are connected by the connecting beam, the connecting beam, the joint, and the side frame are in a mutually reinforcing state, and as a result, the strength is not impaired.

Therefore, the desk of the present invention can be shared with members and diversified in variations without impairing the easiness of packing / transporting which can be disassembled into a plurality of elements.

According to the second aspect of the present invention, the leg of each type is unitized with the side frame fixed in advance, which is advantageous in that the assembling work can be facilitated.
