The present invention relates to a device for attaching a device support arm to a desk top plate.
[0002]
[Prior art]
In recent desks, the shape of the top plate, the combination of the front panel and legs, and the like have become complicated due to various functions such as various wiring and diversification of design.
[0003]
On the other hand, a flat display (hereinafter referred to as FD) arm, a task light, a telephone stand, and other various attached devices are often used around the desk.
[0004]
By the way, when an OA device is installed on a desk top, for example, if an arm for supporting the device is attached to the desk top so that the arm can be rotated, the OA device should be used at a desired position on the desk top. This is preferable.
[0005]
By the way, in order to attach this type of conventional device support arm to the desk, when the top plate is viewed from the front, the top surface is the top plate using a fixture whose cross section is formed in a U-shaped cross section at the rear side which is the back side. Hold the top plate on the surface so that the bottom surface is on the bottom side of the top plate, insert screw parts such as bolts into the screw holes drilled on the bottom surface of the fixture, and the tip of the bolt is on the top plate It is tightened so that it touches the bottom. A support having a pivotable arm or the like is fixed to the upper surface of the fixture in advance, so that if the OA device is installed on the arm, the OA device can be used at a desired position on the desk top plate.
[0006]
[Problems to be solved by the invention]
However, if the desk is mounted from below, a sufficient tightening allowance is required between the top plate and the leg, and if the desk top plate protrudes more outward than the leg or front panel, It is easy to install, but generally there is a problem that it is not easy to tighten from the bottom because the space between the end of the desk top and the leg is narrow, so it is easy to come off, and there is a problem between the desk top and the leg. Even in the case where the space is wide, there is a problem that the desk must be moved and installed one by one in a workplace where desks and other items facing each other are placed.
[0007]
