Height-adjustment device
US-7574965-B2Abstract
In the case of a height-adjustment device for a table ( 1 ) with three or more table legs ( 3.1 . . . 3.4 ) arranged in an edge region of the table, with respectively adjacent table legs ( 3.1 . . . 3.4 ) being connected to one another by a horizontal, hollow-profile connecting element ( 4.1 . . . 4.4 ), each of the table legs ( 3.1 . . . 3.4 ) comprises a telescopic mechanism for changing a length of the table leg ( 3.1 . . . 3.4 ), which mechanism can be adjusted by rotating a rotatably mounted adjusting element ( 7.1 . . . 7.4 ). A plurality of coupling elements ( 9.1 . . . 9.4 ) are accommodated within the connecting elements ( 4.1 . . . 4.4 ) and are arranged in such a manner that each of the adjusting elements ( 7.1 . . . 7.4 ) of the table legs ( 3.1 . . . 3.4 ) is mechanically synchronized with the adjusting elements ( 7.1 . . . 7.4 ) of the adjacent table legs ( 3.1 . . . 3.4 ) by means of separate coupling elements ( 9.1 . . . 9.4 ).
