Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the present invention, a shelf on which OA equipment and the like are usually placed is provided in a desk main body in a housed state. This shelf is raised to the desk surface to put the OA equipment and the like in use. The present invention also relates to a desk with a lifting device which is lowered to a storage state and can move a shelf up and down stably.

[0002]

2. Description of the Related Art OA equipment is raised on a desk,
As means for lowering, for example, the techniques of JP-A-6-112 and JP-A-8-98723 are known. The outline of Japanese Patent Application Laid-Open No. 6-112 has a structure in which an elevating rack on which a display is mounted is moved up and down by an elevating means comprising a vertically movable elevating supporter configured like a pantograph and a balance weight. I have.

The outline of Japanese Patent Application Laid-Open No. Hei 8-98723 is to open and close a top plate which can be turned up and down with a hinge as a fulcrum,
Long left and right guide members, a base member connecting the lower portions of the left and right guide members, a strength member attached to the left and right support frames of the desk body, and a lifting mechanism operated and controlled by a signal from a control unit And a lifting / lowering body supported by the guide member and moved up and down by a lifting / lowering mechanism.

However, in the former case, the structure is complicated because it is configured like a pantograph by means of a link in which the elevating supports are combined in an X-shape. In addition, when the lifting shelf is lowered and the lifting support is fully folded, a large space is required to accommodate the lifting support below the lifting shelf. It is necessary to secure a space for the user to move up and down, which leads to an increase in the size of the entire desk. Moreover, since the elevating rack is supported by the pantograph-shaped elevating support, it is inevitable to swing back and forth, left and right, and stable vertical movement cannot be expected.

[0005] In the latter case, a vertically long screw rod that constitutes a lifting mechanism is disposed, and this long screw rod is rotated forward and reverse by a motor to move the lifting mechanism up and down.
The structure is complicated due to the configuration in which the support table attached to the elevating mechanism moves up and down. In addition, since it has a lifting mechanism that is controlled in operation by a signal from the control unit, there is a problem that the manufacturing cost is extremely high.

The present invention has been made in view of these circumstances, and has a simple structure, in which the auxiliary top plate is rotated and pushed down in the desk main body, so that the shelf in the desk main body can be easily provided via wires and guide rollers. It is an object of the present invention to provide a desk with an elevating device that can raise the desk to the upper part of the desk main body.

[0007]

According to the present invention, an auxiliary top plate is provided at a rear portion of a top plate of a desk body, and a hinge shaft provided on the auxiliary top plate is used as a fulcrum. The auxiliary top plate can be rotated 90 degrees through the guide groove, and the auxiliary top plate is rotated and pushed down in the desk main body, so that the shelf can be raised to the upper part of the desk main body. Is fixed to the desk body, and furthermore, a wire is provided over the guide roller.
