Abstract:
A clamping and/or braking device including:(a) a basic body having an essentially U-shaped cross section with a clamping and/or braking region provided on the inner surface or on the outer surface of one or both legs of the U shape, each clamping and/or braking region for pressurizing an element which is to be clamped; and (b) an actuating mechanism connected to the basic body, the actuating mechanism including a chamber on or in a leg of the U shape on which a clamping and/or braking region is located with the chamber being at least partially bounded by an actuating wall which at least in partial regions is flexible but tension-proof and pressure-resistant, the actuating mechanism for exerting tensile or compressive forces on the basic body to substantially elastically deform the basic body in response to an overpressure or vacuum applied within the chamber, the deformation moving the clamping and/or braking region on the respective leg into or out of a pressurizing position or changing the pressurizing force which the clamping and/or braking region exerts on the element which is to be clamped.
