Abstract
A device comprising: (a) a first working arm; (b) a body; (c) a shuttle, and (d) a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position.
Claims21
A device having a longitudinal axis comprising:
- a. a first working arm;
- b. a body;
- c. a shuttle movable between at least a first position and a second position along the longitudinal axis;
- and
- d. a bias device including a biasing surface;
- wherein the bias device biases the first working arm outward relative to the body when the shuttle is in the first position by physical contact between the biasing surface and the shuttle, the physical contact caused by movement of the shuttle from the second position to the first position along the longitudinal axis;
- and
- wherein the bias device is free of biasing the first working arm outward relative to the body when the shuttle is in the second position, the biasing surface of the bias device being free of physical contact with the shuttle in the second position.
5 more elements
A device comprising:
- a. a first working arm;
- b. a second working arm;
- c. a body;
- d. a shuttle;
- and
- e. a bias device;
- wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position,
- wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position, and
- wherein the shuttle is located on the first working arm and the second working arm is free of a shuttle so that the first working arm is biased when the shuttle is in the first position and the second working arm is freely movable.
6 more elements
A device comprising:
- a. a first working arm;
- b. a body;
- c. a shuttle located on the first working arm;
- and
- d. a bias device extending from the body and comprising an elastically deformable element;
- wherein the first working arm includes one or more deactivation features operable to deactivate the bias device;
- wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, the bias device in physical contact with the first working arm or the shuttle in the first position;
- and
- wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position and the bias device is deactivated, the bias device being free of physical contact with the first working arm or the shuttle in the second position.
