Abstract
A clamping device for fixing a wheelchair drive unit to a wheelchair frame, the clamping device comprising a lever, a first clamping jaw, a second clamping jaw, which are movably mounted on a clamping jaw holder via a jaw path between an open position and a closed position. The lever is movably coupled to the first clamping jaw and the second clamping jaw via a lever path such that a movement of the lever along the lever path causes the clamping jaws to move along the jaw path. A transmission arrangement couples the lever to the first clamping jaw and the second clamping jaw in such a way that, moving the lever by half the lever path causes the first clamping jaw and the second clamping jaw to move by more than half the jaw path in the direction of the closed position of the clamping jaws.

A clamping device for fixing a wheelchair drive unit to a wheelchair frame comprising:
- a lever element;
- a first clamping jaw;
- a second clamping jaw;
- a clamping jaw holder;
- and
- a transmission arrangement, wherein
- the first clamping jaw and the second clamping jaw are movably mounted on the clamping jaw holder via a jaw path between an open position and a closed position,
- the lever element is movably coupled to the first clamping jaw and the second clamping jaw via a lever path such that a movement of the lever element along the lever path causes the clamping jaws to move along the jaw path,
- the transmission arrangement couples the lever element to the first clamping jaw and the second clamping jaw in such a way that, starting from the open position of the clamping jaws, moving the lever element by half the lever path causes the first clamping jaw and the second clamping jaw to move by more than half the jaw path in the direction of the closed position of the clamping jaws,
- the transmission arrangement is configured in the form of an eccentric arrangement,
- the eccentric arrangement has at least one hole guide in which a bolt is arranged that is operatively connected to the lever device, and
- the eccentric arrangement also has an articulated piece that is connected to the first clamping jaw and the bolt and is operatively connected to the lever device via the bolt.
