Abstract
Abstract A handle-connecting assemby for hand-held machine tools comprises a wire element having a loop engaging a tool-supporting projection of the tool and a hollow member adapted to receive the ends of the wire element. The ends of the wire element are rigidly connected to a head of a bolt, the end threaded portion of which is threaded into a handle. The wire element connecting the tool-supporting projection to the handle provides for sufficient flexibility of such connection thereby the handle may positioned at an acute angle to the axis of elongation of the projection.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
A handle assembly for a hand-held machine tool having a housing and a cylindrical projection extending from said housing and adapted to receive a tool, and a handle having an opening, comprising means for connecting said handle to said housing, said means including at least one clamping strand formed with a loop, two end portions and two transition shoulders located between said loop and said end portions, said loop being adapted to encompass said projection; a hollow member positioned between said projection and said handle and adapted to receive said transition shoulders and said end portions; and a bolt having one end rigidly connected to said end portions and another end threadably inserted into said opening of the handle, said clamping strand being formed as a wire element.
Claim 2
Dependent Claim
128 words
A handle assembly for a hand-held machine tool having a housing and a cylindrical projection extending from said housing and adapted to receive a tool, and a handle having an opening, comprising means for connecting said handle to said housing, said means including at least one clamping strand formed with a loop, two end portions and two transition shoulders located between said loop and said end portions, said loop being adapted to encompass said projection; a hollow member positioned between said projection and said handle and adapted to receive said transition shoulders and said end portions; and a bolt having one end rigidly connected to said end portions and another end threadably inserted into said opening of the handle, said clamping strand being formed as a wire element.
Claim 3
Dependent Claim
23 words
The assembly of claim 1, wherein said member has a longitudinal axis, said bolt extending within said member substantially parallel to said axis.
Claim 4
Dependent Claim
20 words
The assembly of claim 2, wherein said transition shoulders extend substantially parallel to the direction of elongation of said projection.
Claim 5
Dependent Claim
25 words
The assembly of claim 3, wherein said bolt including a head facing away from said opening, said end portions being rigidly connected to said head.
Claim 6
Dependent Claim
23 words
The assembly of claim 4, wherein said head is formed with two bores adapted to receive said end portions of said wire element.
Claim 7
Dependent Claim
25 words
The assembly of claim 5, further including two hollow sleeves adapted to receive the ends of said end portions and rigidly connected to said head.
Claim 8
Dependent Claim
