Abstract

A handle for files and similar tools having a tang to be pushed into the handle which is a molded integral plastic body provided with an elongated opening to receive the tool tang, the opening having a flat rectangular section shape over most of its length while at its mouth, there is a cylindrical indentation to prevent excessive stress in the handle body.

Claims

1. A handle of elongated shape substantially symmetrical with respect to a handle axis for a file, a ratchet or another tool having a tang to be driven axially into said handle and subjected, in use, to reciprocal forces parallel to said axis, the handle being made of a plastic material and being provided with an axial opening to receive said tang, said opening extending, from a first end of the handle, thereinto over less than the entire length thereof, said opening having a substantially flat-rectangular section shape except a first portion adjacent thereof said first handle end where said opening has a circular section of a diameter equal to or greater than the greatest sectional dimension of said tang, the axial length of said first opening portion being substantially equal to the axial extension of a bulge rim provided at said first handle end, the entire handle being integrally molded.

2. A handle as claimed in claim 1 in which indentations are provided extending from the outside of the handle thereinto substantially transverse with respect to said axis.

3. A handle as claimed in claim 2 in which at least some of said indentations extend substantially diametrically through the handle.

4. A handle as claimed in claim 1 in which said opening tapers inwardly from said first handle end.

5. A handle as claimed in claim 1 in which the handle has a substantially elliptic section shape, the greater axis thereof being congruent with a greater axis of said flat-rectangular opening section.
