Abstract
A compressible handle for a tool is reversibly compressible along its longitudinal axis during use of the tool. The handle includes a first longitudinal portion and a second longitudinal portion which can slide in opposing directions relative to each other along the longitudinal axis of the handle. The handle further includes a biasing element providing a biasing force to bias the first longitudinal portion and the second longitudinal portion away from each other, and a bias adjustment mechanism by means of which a user can apply and vary a load applied to the biasing element so as to modify the magnitude of the biasing force and thereby adjust the compressibility of the handle.
Claims14
A handle for a tool, wherein the handle is reversibly compressible along a longitudinal axis thereof during use of the tool, the handle comprising:
- a first longitudinal portion;
- a second longitudinal portion slidably attached to the first longitudinal portion, the first longitudinal portion and the second longitudinal portion being mutually slidable in opposing directions along the longitudinal axis of the handle;
- a biasing element providing a biasing force to bias the first longitudinal portion and the second longitudinal portion into mutual distance, the biasing force having a magnitude, wherein application to the handle of a compressive force opposing and overcoming the biasing force is operable to slide the first longitudinal portion and the second longitudinal portion into mutual approach along the longitudinal axis;
- and
- a bias adjustment mechanism operable by a user while the handle remains intact to apply a variable load to the biasing element and to vary the variable load, thereby to modify the magnitude of the biasing force.
A handle for a tool, wherein the handle is reversibly compressible along a longitudinal axis thereof during use of the tool, the handle comprising:
- a first longitudinal portion;
- a second longitudinal portion slidably attached to the first longitudinal portion, the first longitudinal portion and the second longitudinal portion being mutually slidable in opposing directions along the longitudinal axis of the handle;
- a compression spring comprising a first end and a second end and defining an axis of compression aligned with the longitudinal axis of the handle, the compression spring providing a biasing force to bias the first longitudinal portion and the second longitudinal portion into mutual distance, the biasing force having a magnitude, wherein application to the handle of a compressive force opposing and overcoming the biasing force is operable to slide the first longitudinal portion and the second longitudinal portion into mutual approach along the longitudinal axis;
- and
- a bias adjustment mechanism comprising a first stop engaging the first longitudinal portion and abutting the first end of the compression spring, and a second stop fixed to the second longitudinal portion and abutting the second end of the compression spring, wherein the bias adjustment mechanism is operable while the handle remains intact to apply a variable load to the compression spring, and to vary the variable load, thereby to modify the magnitude of the biasing force.
