Patent ID: 7204364

Claim:
A lift device for lifting and lowering a support device ( 2 , 3 B, 5 ) of a transport track segment of a transport device for work pieces, the lift device comprising: a work piece carrier ( 58 ), wherein the work pieces are deposited on the work piece carrier; a force producing device ( 35 , 72 , 73 ), wherein the force producing device produces a force for lifting or lowering the support device ( 2 , 3 B, 5 ); a force transmission device, wherein the force transmission device transmits the force from the force producing device to the support device; and wherein the force transmission device includes at least on lever ( 25 a , 25 b ) having a first end ( 29 a , 29 b ) coupled to the force producing device ( 35 , 72 , 73 ), the first end ( 29 a , 29 b ) guided for horizontal displacement, and having a second end ( 30 a , 30 b ) coupled to the support device ( 2 , 3 B, 5 ), the second end ( 30 a , 30 b ) guided for vertical displacement, wherein the first end ( 29 a , 29 b ) is linked to at least one slide bar ( 16 a , 16 b ) oriented in the horizontal direction, wherein the second end ( 30 a , 30 b ) is linked to at least one lift bar ( 17 a , 17 b ) parallel to the at least one slide bar ( 16 a , 16 b ), and wherein the at least one lever includes two levers, and two slide bars ( 16 a , 16 b ) are provided oriented parallel and bracketing the two levers ( 25 a , 25 b ).
