Abstract
The need for readjustment of clamps due to wear and tear is overcome by the provision of clamping means comprising a first member (16) movable relative to a housing (10) to effect clamping; torque limiting drive means (30,44) rotatable to effect that movement; and lost motion stop means (50,60) rotatable by the drive means into a first stop position in which continued rotation of the drive means is prevented and, through reverse rotation of the drive means, into a second stop position in which continued reverse rotation of the drive means is prevented. This clamping means can be used in particular to clamp telescoping legs, for instance on camera tripods.
