ABSTRACT:
In order to enable quick and easy clamping of a work piece or device to the top of a work bench, the work bench is formed with a plurality of keyhole-like slots which are adapted to receive a threaded shaft and stopper arrangement which extends down from each of a plurality of rocker arm-like clamp members. Each of these clamps is such that a stopper which is provided on the bottom of the threaded shafts, is wider than the width of the slot. Rocker arms, which are connected to the upper ends of the threaded shaft, are each provided with a vertically extending bore through which a threaded shaft extends, and an intersecting lateral bore in which a follower nut which cooperates with the threaded shaft, is received. The lateral bore is formed toward one end of the rocker arm that is adapted to have engagement fingers or members at each end. The follower nuts are each formed with a thread only on one side of the bore through which the threaded shaft is disposed and are each arranged to laterally displaceable so that temporary disengagement between the threads can be achieved to allow for quick setting of the clamps.
