Abstract
A clamp, for example of the conventional "clothes peg" type, is provided with a wedging device 9 which may be selectively locatable between the rear ends of the two clamping members 2 so as to urge the rear ends apart, and thereby by virtue of the pivotal connection 4 between the clamping members 2 to urge the clamping jaws 3 together. In this way the wedging device 9 acts to increase the strength of the clamp in order to reduce the possibility of the items held between the jaws of the clamp from slipping out of the clamp. A locking member is also provided to prevent the wedging member from being unintentionally released.
Claims9
A clamp comprising:
- (a) a pair of clamping members, each said clamping member including a jaw member, and said clamping members being pivotally mounted with respect to each other,
- (b) spring means for biassing said clamping members such that said jaw members are urged towards each other,
- (c) a guide means located between said clamping members,
- (d) wedging means adapted to slide upon said guide means until said wedging means contacts the clamping members to thereby urge the ends of said clamping members remote from said jaw members apart, whereby said jaw members are urged together, and
- (e) selectively engageable screw drive means for tightening of the wedging means against the clamping members.
