Description

[Detailed description of the invention] [Industrial field of application] This invention proposes that when lighting equipment, shelves, etc. are installed on the top of a study desk or office desk, the supports supporting the lighting equipment or shelves can be attached to the top of the desk. This invention relates to a device for attaching the device to stand on a leg exposed on the upper side.

[Prior Art] Conventionally, as a technique for erecting the supports of lighting equipment, shelves, etc. so as to protrude upward from the corners of the desk top plate, there is a technique disclosed in the prior art, Japanese Utility Model Application No. 56-93907. A pair of insertion pieces that protrude downward from the lower end of the column are inserted into the upward openings of the legs attached to the corners of the desk top plate, and the stopper pieces that protrude inward approximately horizontally into the inside of the legs are inserted. A configuration in which the insertion piece is supported by the support member, while the downwardly protruding insertion piece of the leg body is clamped by setscrews screwed onto two opposing sides of the leg body, thereby eliminating wobbling of the support column. is disclosed.

[Problem that the invention attempts to solve]

According to the prior art, the pair of insertion pieces protruding downward from the lower end of the column is expanded downward to prevent rattling against the inner surface of the leg. It is difficult to insert it into the upper end opening, making the operation difficult.

Furthermore, since the downwardly protruding insertion piece of the leg is held between the two opposing set screws that are screwed into the side surfaces of the leg, the heads of both set screws are always protruding from the outer side of the leg. As a result, the appearance of the legs will deteriorate, and the heads of the setscrews will protrude sideways from the sides of the legs at the corners of the desk. There was also the problem that it got in the way when they were placed closely together so that they were in contact with each other.

The present invention aims to solve such problems.

[Means for solving problems]

Therefore, in the present invention, the legs supporting the desk top are formed in a hollow shape at the corners of the desk top, and the upper ends of the legs are connected to the upper surface of the desk top through the notches provided at the corners of the desk top. An upwardly-opening funnel-shaped supporting member into which the lower end of a support such as a lighting fixture fits is provided inside the leg at an appropriate position below the upper end of the leg, and the lower end of the supporting member An inward stopper piece is provided to which the lower end of the support of the lighting equipment comes into contact, while a corner cover body that covers the upper opening of the leg is fitted to the upper end of the leg, and the corner cover body is fitted with a corner cover body that covers the upper opening of the leg. A through hole into which the support column fits is bored, and an annular steady rest kifp is inserted between the through hole and the outer surface of the support support.

[Action/Effect]

According to this configuration, the lower end of the column is fitted into the upwardly-opening funnel-shaped support member provided in the hollow leg, so the opening area of the upper end opening of the leg is also smaller than that of the funnel-shaped support member. The area of the upper end opening is also larger than the area of the lower end of the column, making it easier to insert the lower end of the column into the leg and the cylindrical support member.

Since a corner cover body covering that portion is fitted into the leg upper end opening located above the cylindrical support member, the area of the leg upper end opening is larger than the through hole bored in the corner cover body. There is no problem.

The gap between the through hole of the corner cover body and the outer surface of the midway part of the pillar inserted into the through hole is filled by the inserted annular steady rest cap,
In addition, the annular steady rest cap can support the middle part of the support column to prevent it from swinging from side to side, resulting in an effect that the appearance of the desk is greatly improved compared to the conventional set screws.

Since the annular steady rest cap is located on the upper surface of the corner cover body, there is no protruding part on the outer surface of the leg unlike in the conventional case, and in this respect as well, the appearance of the desk can be improved and the closeness of adjacent desks can be improved. It also has the effect of not getting in the way.
