Abstract
A clamp usable as a vise has a fixed clamping member and a movable clamping member movable toward and away from the fixed clamping member along a guide. A tippable locking element has a hole through which passes an elongated locking element that extends in the direction of displacement of the clamping member. The tippable element can be displaced between a slide position wherein the hole loosely surrounds the elongated element and allows it to move relative to the tippable element and a locked position with the tippable element canted and the elongated element wedged in the hole. Furthermore once the tippable element is in the canted position it can further be displaced so as to bring extra clamping force to bear on a workpiece between the two clamping members.
Claims23
A clamp comprising:
- a fixed clamping member;
- a movable clamping member displaceable through a relatively long distance toward said fixed member in a closing direction and away from said fixed member in an opposite opening direction;
- a tippable locking element having a hole;
- an elongated locking element received in said hole said extending in said direction;
- means for displacing said tippable element between a slide position with said hole loosely surrounding said elongated element and a locked position with said tippable element canted and said elongated element wedged in said hole;
- and
- means expansible in said directions through a relatively short distance and including a nut bearing in one of said directions against one of said locking elements and a threaded element threaded through said nut and bearing in the other direction against one of said members, the other locking element bearing in the other direction against the other member.
A clamp comprising:
- a fixed clamping member;
- a movable clamping member displaceable through a relatively long distance toward said fixed member in a closing direction and away from said fixed member in an opposite opening direction;
- a tippable locking element at one of said members and having a hole;
- an elongated locking element extending in said directions and nondisplaceable in said directions relative to the other of said members, said elongated locking element being received in said hole and said tippable element being displaceable between a slide position with said hole loosely surrounding said elongated element and a locked position with said tippable element canted and said elongated element wedged in said hole;
- a body having a formation at said one member extending at an inclination to said directions and nondisplaceable in said directions relative to said one member;
- a body bearing in one of said directions on said formation and in the other of said directions on said tippable element;
- and
- means for rotating one of said bodies about an axis generally parallel to said direction relative to the other body and thereby relatively oppositely displacing said bodies by means of said formation through a relatively short distance in said directions so as to displace said tippable element from said slide position to said locked position and thereafter to displace said elements relative to said one member.
