SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is intended to solve the problem when a plurality of tables having four corners of a top plate supported by pillars are installed adjacent to each other. By eliminating the need for extra pillars, the appearance can be reduced and the appearance can be reduced.The cost can be reduced. It is another object of the present invention to provide a table leg device that can be used.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is a table leg apparatus in which four corners of a top plate are supported by pillars, and a plurality of tables are arranged adjacent to each other. In this case, the pedestal is attached to the top plate symmetrically at least at four places at the upper end of the pedestal so that the pedestal is attached across the corners of the adjacent top plate and shared by a plurality of adjacent tables. And a table leg device having an optional supporting portion such as a panel in the center.

[0007] Further, a notch of a quarter circle is formed in at least two adjacent corners of the top plate so that the support portion of the pillar can be exposed from the notch. In a state where the pillar is attached to the inside of the corner, it is preferable that the pillar can be attached so that the pillar is not exposed to the notch.

Then, the supporting portions of the pillars are exposed to the openings formed by the cutouts of two or four adjacent top plates, and the butting portions of the top plate are utilized using the plurality of supporting portions. The panel is attached along the line.
