Abstract
A tool handle having a core (2) adapted to be secured to a screwdriver blade (1), and a sleeve (3) of plastics material placed around the core. The core and the sleeve have portions in relief (9, 20) for mutual positioning in rotation, and mutual positioning devices (5, 10, 11, 14, 17, 21, 22) for mutual positioning in axial translation. The sleeve (3) is a part that is distinct from the core, and is made of a semi-rigid plastics material and is engaged on the core (2) from in front.
Claims13
A handle for a tool, the handle comprising:
- a core formed of rigid material and being adapted to be secured to a blade of the tool;
- and
- a sleeve formed of semi-rigid plastics material, said sleeve being press-fitted onto the core, wherein said core and said sleeve are each provided with relief portions for mutual positioning in a rotational direction, and mutual positioning means for mutual positioning in an axial direction,
- wherein the sleeve is a part that is distinct from the core, and the semi-rigid material is substantially non-deformable so as to permit the sleeve to be press-fitted onto the core from a front end thereof,
- wherein the mutual positioning means comprise rear abutment means and locking means for locking the sleeve in a rear abutment position,
- wherein the locking means comprises cooperating portions in relief on the core and on the sleeve, said cooperating portions in relief being hidden by the sleeve, and
- wherein the locking means further comprises complementary surfaces on said core and said sleeve, wherein said complementary surfaces extend from the front end faces of said core and said sleeve and converge rearwardly so as to lock the sleeve in its rear abutment position.
