Abstract

Abstract Handle for manual percussion tools having a metal tube covered with plastic cases of varying rigidity which affect different areas of the tube. The tube constitutes the core of the handle and has a preferably elliptic section with two coaxial portions of approximately the same length and different width and near the free end of the narrower portion there is a deformation which affects the lateral surface. The portion of the tube of greater section receives a dismountable casing shaped for manual gripping of the handle. The portion of the tube of lesser section immovably receives a rigid plastic covering preferably of acetate, having a graded extreme area of lesser dimensions than the rest and has the general shape of a rectangular truncated pyramid concealing the deformation.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 126 words
A handle for manual percussion tools of the type having a striking head, said handle comprising: a core element formed of a metal tube, said tube throughout is length having a substantially elliptical cross-section, said tube having first and second sections of substantially equal length, said first section having a larger transverse dimension than said second section, said first and second sections being joined by a stepped portion, said second section adjacent the free end thereof being deformed inwardly to form a constriction; a casing formed of elastic material positioned over said first section; and a covering positioned over the entire length of said second section, said covering being formed of a material having a rigidity different from that of said elastic material of said casing.
Claim 2
Dependent Claim 126 words
A handle for manual percussion tools of the type having a striking head, said handle comprising: a core element formed of a metal tube, said tube throughout is length having a substantially elliptical cross-section, said tube having first and second sections of substantially equal length, said first section having a larger transverse dimension than said second section, said first and second sections being joined by a stepped portion, said second section adjacent the free end thereof being deformed inwardly to form a constriction; a casing formed of elastic material positioned over said first section; and a covering positioned over the entire length of said second section, said covering being formed of a material having a rigidity different from that of said elastic material of said casing.
Claim 3
Dependent Claim 17 words
A handle as claimed in claim 1, wherein said casing is removably positioned over said first section.
Claim 4
Dependent Claim 16 words
A handle as claimed in claim 2, wherein said elastic material of said casing is P.V.C.
Claim 5
Dependent Claim 17 words
A handle as claimed in claim 1, wherein said covering is immovably positioned over said second section.
Claim 6
Dependent Claim 15 words
A handle as claimed in claim 4, wherein said material of said covering is acetate.
Claim 7
Dependent Claim 42 words
A handle as claimed in claim 1, wherein said covering at the end thereof adjacent said free end of said second section is tapered to form a portion having the shape of a rectangular based truncated pyramid, said portion concealing said constriction.
Claim 8
Dependent Claim 48 words
A handle as claimed in claim 1, wherein said constriction is made in the direction of a lesser axis of said elliptical cross-section of said tube, the walls of said tube at said constriction in the direction of the greater axis of said elliptical cross-section being outwardly bulged.
Claim 9
Dependent Claim 54 words
A manual percussion tool including the handle as claimed in claim 1, and further comprising a striking head placed on said handle; and a wedge insertable into said free end of said second section to force the walls of said tube at said constriction outwardly when said striking head is placed on said handle.
Claim 10
Dependent Claim 33 words
A manual percussion tool as claimed in claim 8, further comprising a hardenable plastic material insertable into a space formed between the exterior of said handle and the interior of said striking head.
