Abstract
An extensible handle for applying increased torque to a tool headpiece, such as a ratchet wrench. The handle includes a sleeve which carries the tool headpiece. A rod is telescopically received within the sleeve and is resiliently biased towards an extended position. A latch is provided for locking the rod in at least a first retracted position of lesser torque and a second extended position in which greater torque may be applied to the tool headpiece.
Claims5
An extensible tool handle for applying different degrees of torque to a tool headpiece, which handle comprises, in combination:
- a. a sleeve for supporting the tool headpiece at one end of the sleeve,
- b. a rod telescopically received within the other end of the sleeve and having at least one I-shaped groove along the surface thereof for permitting the rod to assume at least one position of retraction and at least one position of extension with respect to the sleeve,
- c. resilient means disposed within the sleeve for biasing the rod towards the position of extension,
- d. latch means carried by the sleeve for engaging the groove and locking the rod against movement with respect to the sleeve in the positions of retraction and extension, and
- e. a handgrip carried by the free end of the rod, which handgrip remains substantially entirely outside of the sleeve when the rod is in the position of retraction.
