Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel support device for arranging and supporting a floor panel on an office floor for installing office automation equipment on the floor.

[0002]

2. Description of the Related Art When a floor panel is arranged at an appropriate distance from the floor, the floor is wavy, so that the lower end portion of the supporting leg does not come into contact with the floor, resulting in an uneven portion. Therefore, the support leg screwed through the floor panel is inserted through a hole above the floor panel and rotated to adjust the downward protrusion amount of the support leg.

However, when the floor is used for a long period of time, the support leg rotates by a small amount, the screw portion is loosened, and an unsteady portion is generated. As a countermeasure against this, conventionally, for example, the actual exploitation Sho 61-1
As shown in Japanese Patent No. 50930, a supporting leg screwed into a supporting cylinder provided in a hole of a floor panel is inserted into a driver through a hole above the floor panel, and the supporting leg is rotated so that no uneven portion is generated. After such adjustment, there is a fixing method in which a loosening preventing male screw short cylinder is screwed in from above the support leg so as to prevent the loosening of the screw portion by a so-called double nut fixing method.

[0004]

However, in the above-mentioned conventional locking device, the support legs are first rotated,
Adjust so that there is no unevenness, and then screw in the loose-fitting male screw short cylinder from above the support legs, so it will take time to install the floor panel, and with a driver for the support legs. , I had to prepare two types of drivers for the male screw short cylinder for locking.

According to the present invention, the floor panel can be quickly installed by one driver by inserting the driver, rotating the support leg, and adjusting the position to prevent the uneven portion, and then automatically forming the locking member. It can be so.

[0006]

In order to achieve the above object, the floor panel supporting device of the present invention is configured such that a rotary tool is inserted through a hole formed in an upper portion of the floor panel and a supporting leg is screwed in and out. In a floor panel support device in which the height of the floor panel is adjusted, a rotation stopper metal that is restricted from rotating and can be raised and lowered with respect to the support leg is provided between the surface plate of the floor panel and the support leg. At the abutting part between the stopper and the front panel of the floor panel, when the stopper is in contact with the front panel of the floor panel, the stopper prevents the relative rotation between the stopper and the front panel, and A feature is provided in which, when the floor panel is detached from the surface plate, a rotation restricting portion is provided for removing rotation regulation between the detent metal fitting and the surface plate, and the detent metal fitting is separated from the surface plate of the floor panel by inserting a rotary tool. I am trying.

[0007]

[Function] When the rotary tool is inserted through the upper hole, the rotation restriction between the rotation stopper and the surface plate is released, and then the support leg is screwed in and out by the rotary tool to adjust the height of the floor panel. You can After adjusting the height of the floor panel,
When the rotary tool is removed, the anti-rotation metal fittings come into contact with the surface plate of the floor panel, and the rotation restricting part regulates the relative rotation between the anti-rotation metal fittings and the surface plate. You can quickly install the floor panel with the driver.
