Abstract (en)
[origin: EP1211022A2] The clamping device (5) includes a clamp lever (5) with a cam-type raised contour having a saddle region extending the length of the lever rotation axle, the saddle region. A spring acting upon a first flank of this saddle region exerts a torque force on the lever in the clamp rotary direction. The saddle region has a dead point where the spring can exert no torque force on the lever. The spring can also act upon a second flank on the opposite side of the saddle region of the first flank, exerting a torque force on the lever in the opposite direction to the clamp rotary direction. The clamping device comprises a clamp lever rotatable about an axle extending parallel to the rear side (7) of the sanding plate (2). The side of the lever facing the narrow side (4) of the sanding plate defines a clamping surface or edge which urges the edge region of the sanding sheet against the rear side of the sanding plate. A spring keeps the lever in the clamping position. A hand-operated actuator is used to swing the lever into an open position where its clamping surface or edge is raised above the rear side of the sanding plate. An Independent claim is also included for a clamping device including a clamp lever with a cam-type raised contour having a saddle region extending the length of the lever rotation axle, the saddle region having two flanks. The rotation axle is elastically bendable and by bending it towards the rear side of the sanding plate it acts as a spring. In the clamping position the lever has its clamping surface against the rear side of the sanding plate and its first flank against a counter-bearing on the rear side of the sanding plate, so that a torque is generated in the clamp rotary direction. In the open position the lever is supported against this counter-bearing only via its second flank.
