ADJUSTING MECHANISM FOR KINEMATICALLY GUIDING AN ADJUSTING BODY DURING DISPLACEMENT ON A SUPPORTING STRUCTURAL PART, ADJUSTING MECHANISM FOR KINEMATICALLY ADJUSTING A VERTICALLY LIFTING BODY AND VERTICAL LIFT SYSTEM COMPRISING SAID TYPE OF ADJUSTING MECHANISM

摘要

An mechanism for kinematic guidance of a body during its adjustment on a supporting structure. The body is moved between a refracted position and an extended position while performing a movement in a longitudinal direction in combination with a rotary movement. The mechanism includes first and second transmission levers for coupling to the supporting structure, a base connection lever to which these levers are coupled, third and fourth transmission levers coupled to the base connection lever, an adjusting lever coupled to the third and fourth transmission levers for attachment of the adjustable body, to adjust the body by a movement of the adjusting lever, and a coupling lever coupled to the first or second transmission lever and to the third or fourth transmission lever. During a movement of the adjusting lever, the first and second transmission levers each move opposite to the third and fourth transmission levers.
