Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is of a type in which a top plate is supported by a plurality of leg columns independent of each other, and is preferably used in an office or the like. Related to the desk.

[Prior Art] Conventionally, as this type of desk, there is known a desk in which a corner portion of a frame is supported by leg columns and a top plate is mounted on the frame.

[Problems to be Solved by the Invention] By the way, in such a structure, since the side panel or the front panel does not exist as a structural member, when it is desired to conceal the front side or the side side of the desk, a special curtain board is used. Need to be installed between the leg columns.

As a measure for mounting such a curtain plate, it is conceivable that the upper edge of the curtain plate is suspended and supported by a frame via a bracket, and the lower end side thereof is fixed to a leg support via a bracket.

However, when the bracket is fixed to the leg support by bolts or the like, bolt holes are exposed in the leg support when the curtain plate is removed and used. Since the leg support part is a part that is easily exposed to the eyes of the user and others,
If it is left as it is, the appearance will be impaired. Therefore, it is necessary to cover the screw hole with a cap or the like. Moreover, in order to be able to mount the curtain plates having various vertical dimensions, it is necessary to provide screw holes at various height positions of the leg support, and the treatment should be done so as not to damage the appearance. It gets harder and harder.

It is an object of the present invention to make sure the mounting state of the curtain plate to the leg support and to solve such a problem.

[Means for Solving the Problems] The present invention takes the following means in order to achieve the above object.

That is, the desk according to the present invention is such that the leg support supports the lower end side of the curtain plate via a pair of brackets, and the leg support has an opening edge portion at its inner edge portion rather than the inside. The narrow groove is formed continuously in the vertical direction. The curtain plate is disposed between the leg columns in a suspended state. One of the brackets has such a thickness that the rotation of the bracket can be locked in a posture in which the tip of the bracket is inserted into the groove of the leg column and horizontally rotated to a position of about 45 ° with respect to the opening direction of the groove. It is a set plate-like member, and has a slit that opens at the upper edge or the lower edge at a portion corresponding to the opening edge portion of the tip end portion. The other bracket is formed by bending the tip end portion having the same thickness as that of the one bracket in the thickness direction by about 90 ° with respect to the base end portion, and a lower edge or a part of the tip end portion corresponding to the opening edge or It has a slit that opens to the upper edge. Then, the front end portions of the both brackets are inserted into the common groove in an orthogonal state, the slit forming portions of the both brackets are meshed with each other from above and below, and the base end portions of both brackets are overlapped to form a common inner surface of the curtain plate. It is characterized in that they are fastened together using a fastener.

In order to save the trouble of manufacturing two kinds of brackets having different shapes, it is preferable that the other bracket has a shape obtained by bending the tip portion of one bracket.

When bending the tip of one bracket to obtain the other bracket, if you want to avoid shifting the holes for inserting bolts etc. due to bending, etc., place the bracket in the vertical center at the base end. It is advisable to bore long holes extending in the horizontal direction, and to insert bolts as fasteners into these both long holes.

[Operation] With such a configuration, the tip portions of both brackets are inserted into the grooves of the leg columns separately, and then the both brackets are slid in the direction along the groove to form the slit forming portion. When they are engaged with each other, both brackets cannot be pulled out from the groove. In this way, when the slit forming parts are engaged with each other so that the front ends of both brackets are orthogonal to each other, the base ends of both brackets are superposed, and the superposed base ends are attached to the inner surface of the curtain plate. The curtain plate can be joined to the leg support by co-fastening. In this way, when the base end is fixed to the curtain plate together, both brackets cannot move relative to each other in the vertical direction. It will never be released.
