Abstract

Each of a plurality of leg units (U1 to U4) for supporting a top plate (2) have a support column (5) and a foot section (6). The plurality of leg units (U1 to U4) are divided into a first leg unit group (G1) along one long side edge “a” of the top plate (2) and a second leg unit group (G2) along the other long side edge “a”. The first operation units (301) corresponding to the first leg unit group (G1) and the second operation units (302) corresponding to the second leg unit group (G2) are operated individually, to change the lengths of the support columns (5) belonging to the leg unit set (G1) and the second leg unit set (G2) to the different lengths, so that the top plate (2) is tilted.

1 . A table provided with a top plate, a plurality of leg units and a plurality of operation units, said each leg unit has a support column and a foot section, said support column has upper and lower ends, the length of the direction connecting the upper and lower ends being changeable, and the upper end being connected to the top plate, and said foot section is connected to said lower end of said support column and is adapted for seating on the floor, said lengths of said support columns of said plurality of leg units are changeable by operating one or more said operation units, wherein
 said each leg unit belongs to either a first leg unit group which includes one or more leg units and arranged on one side of the top plate or a second leg unit group which includes one or more leg unit and arranged on the other side of the top plate,   said each operation unit comprises a first operating section for changing the lengths of the support columns of the leg units belonging to the first leg unit group, and a second operating section for changing the lengths of the support columns of the leg units belonging to the second leg unit group, the second operating section being operable independently of the first operating section.   
     
     
         2 . A lifting table according to  claim 1 ,
 in each of said leg units, said foot section comprises a foot body portion which is mounted on said support column and extends in a direction between said one side of the top plate and the other side, and plurality of foot portions which are spaced in the direction of their extension and are adapted for seating on the floor.   
     
     
         3 . A lifting table according to  claim 2 ,
 the foot body portion of said leg unit is fixedly mounted on said support column, the foot portions are mounted on said foot body portion in a manner that the length of each foot portion protruding relative to the foot body portion in the direction to the floor can be changed,   said protruding lengths of said foot portions relative to the foot body portion can be changed corresponding to the tilt angle of the top plate.   
     
     
         4 . A lifting table according to  claim 2 ,
 the foot body portion of said leg unit is mounted on said lower end of the said support column in a manner that the mounting angle can be changed,   the mounting angle of the foot body portion relative to said support column can be changed corresponding to the tilt angle of the top plate.   
     
     
         5 . A lifting table according to  claim 1 ,
 both the first and second leg unit groups have more than two leg units,   the support columns of the leg units belonging to the first leg unit group are in a common first support column configuration plane,   the support columns of the leg units belonging to the second leg unit group are in a common second support column placement plane,   said first configuration surface and second configuration surface are parallel to each other.   
     
     
         6 . A lifting table according to  claim 1 ,
 said foot portions mounted on the support columns of the leg unit belonging to the first leg unit group and said foot portions mounted on the support columns of the leg unit belonging to the second leg unit group are connected by the connecting member so that the relative position changes of the both said foot portions resulting from the inclination of said top plate can be absorbed.   
     
     
         7 . A listing table according to  claim 1 ,
 said leg units includes four leg units, each arranged at point corresponding to the four vertices of the parallelogram,   said one side and said other side of the top plate are the two opposite sets of sides of said parallelogram,   with respect to each of the two sets of sides of the top plate, said foot units are defined as belonging to either a first leg unit group or a second leg unit group, and two operating sections are defined as belonging to either a first operating section or a second operating section.   
     
     
         8 . A lifting table according to  claim 7 ,
 said each leg unit includes a top plate support structure that is mounted on the top plate and the upper end of the support column, for connecting the upper end of the strut to the top plate,   in each of said leg units, one of the operating sections belonging to said first operating section and one of the operating sections belonging to second operating section extends into said top plate support structure, and the length of the support column can be changed by operating either of said two operating sections.   
     
     
         9 . A lifting table according to  claim 1 ,
 the foot sections are rotatably mounted on said support columns according to the selected tilt direction so that the direction in which said foot body portion extends follows said tilt direction.   
     
     
         10 . A lifting table according to  claim 1 ,
 the height of the top plate can be changed by changing the support column lengths of the leg units belonging to the first and second leg unit groups to the same length.
