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.
Claims20
A tool, comprising:
- a handle that includes a first handle element having a first head section;
- a jaw subassembly that includes a base ring and a plurality of jaws, the base ring having a central axis and being rotatably mounted proximate the head section, each jaw being pivotably mounted to the base ring, each jaw having an engagement surface and a first side wall extending from the engagement surface, and each jaw having a first cam follower protuberance extending outwardly from the first side wall;
- and
- a controller mounted to the handle and coupled to the base ring such that rotation of the controller causes rotation of the base ring relative to the handle;
- wherein the first head section includes a plurality of first cam slots;
- and
- wherein each first cam follower protuberance engages a given one of the first cam slots such that rotation of the base ring relative to the head section causes the jaws to pivot in concert with each other toward or away from the central axis of the base ring.
