Abstract
Adjustable-size jaw sub-assemblies, jaw assemblies made from such sub-assemblies, and tools, particularly hand tools, made using such jaw assemblies. A plurality of jaws are connected to a base ring by pivot pins. Cam follower recess can be defined at positions of the inner perimeter of the base ring, and between opposing faces of the base ring. In the jaw assemblies, an actuator, such as a cover plate, covers at least a portion of one of opposing faces of the base ring, and one or more bridges connect the jaws to the actuator. Movement of the base ring relative to the actuator causes the jaws to pivot about the pivot pin axes, with the jaws moving in concert with each other thereby to reduce or expand the size of a work opening defined by the jaws.
Claims39
A jaw subassembly, adapted to be used as part of a jaw assembly, said jaw subassembly comprising:
- (a) a base ring, having first and second opposing faces, a first outer perimeter of said base ring extending between the first and second opposing faces, a base ring aperture being disposed inwardly of the outer perimeter, the base ring aperture having an inner perimeter and a central longitudinal axis;
- and
- (b) a plurality of jaws, each said jaw having a jaw base, and a jaw extension displaced from the respective said jaw base, each said jaw being connected to said base ring by a pivot pin such that the respective said jaw can pivot about the respective said pivot pin at a respective jaw pivot axis, at least one cam follower recess being defined by the inner perimeter of said base ring.
