<p>The shank of the clamping device is connected to the actuating element via a freewheel and is supported on the cover via a counteracting further freewheel. Located on the shank fixedly in the terms of rotation and displacement is the first coupling part which interacts with a second coupling part mounted at a fixed location. The latter is connected to the winding-up element for the clamping cables via a bevel gear. Formed on the actuating element is a slot-shaped groove which slides along the fixed guide pin during the pivoting of the actuating element. For tensioning the clamping cables, the actuating element is pivoted in such a way that the groove part is located at the guide pine. The shank is thereby lifted into the upper clamping position and the coupling is closed. During the pivoting of the actuating element to and fro, the clamping cables are wound onto the winding-up element. To release the clamping cables, the actuating element is pivoted in such a way that the groove part is located at the guide pin. The shank is thereby lowered into the lower release position, the first coupling part separating from the second coupling part. The winding-up element is thereby freely rotatable.</p> |
