Document Type and Number:
Japanese Patent JP2020171388
Kind Code:
A
Abstract:
To provide a non prepared soil corresponding leg length adjusting unit capable of corresponding to inclination or irregularity of an installation place, reducing a labor and a time for grounding all legs and installing horizontally a top plate when a table is installed on non-prepared soil.SOLUTION: A leg length adjusting unit comprises: a plurality of legs each having leg members with means for extending/reducing leg length according to a fluid amount, and an opening/closing valve 5 on a fluid path 4 to the extending/reducing means; and a valve linkage mechanism 7 to which paths 4 for a fluid 6 of all legs are integrally connected through the opening/closing valve 5 of each leg, and which can open/close all of the valves 5 in a unitary manner. The leg length adjusting unit is provided as one-touch installation means capable of installing a table horizontally or at a required inclination even in installation on non-prepared soil, by causing the valve linkage mechanism 7: to open all of the valves 5 to uniformize pressure throughout fluid 6 so as to ground all of the legs, eliminating wobble, while using a level vial to correct inclination of a top plat; and then, to close the valves 5 to fix the leg length of all legs.SELECTED DRAWING: Figure 2
