<p>A device for translating movements in one plane to movements in a perpendicular plane wherein a first member, movable on a frame with a reversible drive, has gripping arms attached to it. A second movable member is also attached to the first member and connected to the arms. The first member has a lock mechanism for the second member, interacting with stops on the frame. The drive is attached to the second member, the first and second members being releasably connected by the lock mechanism. A connector links the arms to the second member which is released from the lock mechanism when the first member as well as the arms have reached an end position. Depending on the setting of the drive, the second member continues its displacement to move the arms, via the connector, perpendicularly to the plane of movement of the first and second members.</p> |
