Cam actuated, adjustable clamp

Apparatus for clamping a device to a work surface, at an edge of the work surface, the apparatus being disposed generally at the edge and adjacent one side of the work surface, and the device being disposed generally at the edge and in contact with an opposite side of the work surface, comprising:

• (a) a member that is attached to the device;
• (b) an elongate handle having two opposite ends, a cam being disposed adjacent to one end of the handle, the other end of the handle comprising a grip, said handle being pivotally coupled to the member;
• (c) an elongate lever having two opposed ends, a surface disposed adjacent one end of the lever riding on the cam of the handle, a socket being disposed at the other end of the lever, said lever being pivotally coupled to the member, rotation of the handle by a user causing the cam to apply a force on the surface of the lever that produces a corresponding rotation of the lever;
• (d) a bolt disposed in the socket and adjustable relative to the lever to accommodate a thickness of the work surface;
• and
• (e) a shoe coupled to an end of the bolt, said shoe applying a compressive force against said one side of the work surface, relative to the device in contact with the opposite side of the work surface, as the handle is pivoted to a closed position, said shoe moving away from said one side of the work surface as the handle is pivoted to an open position, the closed position of the handle causing the device to be clamped to the work surface and the open position enabling the device to be removed from the work surface.
