Abstract:
A clamping sander for receiving and holding a sheet of sandpaper, the clamping sander comprising:a chassis plate having an upper surface and a lower surface; a clamp plate having an upper surface and a lower surface, the clamp plate being coupled to the chassis plate and movable between a released position spaced from the chassis plate and a clamped position with the lower surface engaging the upper surface of the chassis plate; a grip coupled to the chassis plate for being grasped by an operator for using the clamping sander; and a clamping mechanism carried by the chassis plate and the clamp plate for moving the clamp plate between the released position and the clamped position, the clamping mechanism operated by rotation of the grip and including a camming surface extending from the upper surface of the clamp plate adjacent an aperture formed therethrough, a post extending substantially perpendicularly from the upper surface of the chassis plate and received through the aperture in the clamp plate, and the grip rotatably coupled to the post and including a cam extending from a lower portion thereof, the cam engaging the camming surface to force the grip away from the upper surface of the clamping plate, moving the clamping plate into the clamping position, the camming surface includes a pair of opposing semi-circular camming surfaces encircling the aperture in the clamp plate, and the cam includes a pair of opposing semi-circular cams riding on the camming surfaces.
