BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg apparatus for a table and a desk, and more particularly to a highly versatile leg apparatus which can be mounted according to the size of a table or a table top. .

[0002]

2. Description of the Related Art Conventionally, tables and desks in which at least three or more pillars are provided on a top plate are known. Here, it is also known that the pillar has a structure in which a fixed plate fixed to the upper end thereof is independently attached to the lower surface of the top plate by screwing. Further, between each of the adjacent pillars below the top plate,
A structure in which a crosspiece is provided to increase the strength of a leg is also known.

However, when each pillar is independently mounted on the lower surface of the top plate, the lateral strength of the pillar is insufficient. In addition, when a horizontal rail is directly provided between the upper and lower intermediate portions between adjacent pillars in order to increase the lateral strength of the pillar, it is necessary to form a connecting portion to the pillar at the end of the horizontal rail. However, when the distance between the pillars is different, that is, when the size of the top plate is different, it is necessary to create a horizontal rail according to the dimensions of the top plate, which hinders cost reduction. Was.

[0004] Further, when the width of the top plate becomes large, it is necessary to reinforce the bending of the top plate. Usually, the top plate is provided with a reinforcing member fixed to the lower surface of the top plate, or the top plate itself has a high strength structure. However, an increase in cost is inevitable in any case. In addition, if the top plate is fixed to the leg frame fixed by the horizontal rail between the upper ends of each pillar, the lateral strength of the pillar can be improved and the bending of the top plate can be suppressed, but the versatility as the pillar is improved. It is gone.
