Abstract
Abstract A handle mounting for cleaning implements (brooms, scrubbers, squeegees or the like) comprises a forked connecting member whose fork arms are at one end securable to the head of the cleaning implement and at the other end, interconnected by a crosspiece, are inserted into one end of a tubular metal stem forming the handle or a portion thereof. The connecting member is secured in the stem by deformation of the latter between the two arms of the fork until the tube wall forms two layers, also by welding. The inserted parts of the fork arms, beyond the deformed end of the tube, are bent so as to bear on opposite faces of the tube wall. A cranked arrangement of the outer ends of the fork arms, for engagement with the cleaning implement, are described.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
Handle mounting for cleaning implements, such as brooms, scrubbers, mops, and the like, comprising a fork-like connecting member having fork legs with free ends, the free ends of the fork legs being attachable to the body of the cleaning implement, and the fork-like connecting element additionally having a bridge connecting the fork legs and being inserted in the end of a tubular metallic handle and being fixed in position within the end of the handle, characterized in that the fork legs extend into the cylindrical part of the tube and are bent in an undulating shape at right angles away from the plane formed by the legs, wherein the apex of the bend of the fork legs on the one hand, and the bridge connecting the fork legs on the other hand, are supported on approximately opposite locations of the tube wall.
Claim 2
Dependent Claim
142 words
Handle mounting for cleaning implements, such as brooms, scrubbers, mops, and the like, comprising a fork-like connecting member having fork legs with free ends, the free ends of the fork legs being attachable to the body of the cleaning implement, and the fork-like connecting element additionally having a bridge connecting the fork legs and being inserted in the end of a tubular metallic handle and being fixed in position within the end of the handle, characterized in that the fork legs extend into the cylindrical part of the tube and are bent in an undulating shape at right angles away from the plane formed by the legs, wherein the apex of the bend of the fork legs on the one hand, and the bridge connecting the fork legs on the other hand, are supported on approximately opposite locations of the tube wall.
Claim 3
Dependent Claim
53 words
A handle mounting as claimed in claim 1, wherein the bridge is secured in the handle by the end of the handle being deformed between the fork legs until the handle forms two layers and wherein the two layers formed by the tube wall in the two-layer area are connected by spot welds.
Claim 4
Dependent Claim
48 words
A handle mounting as claimed in claim 1, wherein the tubular handle comprises a seamed tube, the connecting member is inserted in said end of the tube in such a way that the seam is between the fork arms, and said layers are welded together in this area.
Claim 5
Dependent Claim
30 words
A handle mounting as claimed in claim 1, wherein the wall of the handle is fixed to the fork arms by spot welds in the area adjoining the fork arms.
Claim 6
Dependent Claim
69 words
A handle mounting, as claimed in claim 1, wherein the fork leg of the connecting member are substantially parallel and, for insertion of said leg in apertures in the implement head so as to be secured therein non-positively by means of spring force, the fork arms are bent at their free ends through approximately 90° to engage behind the implement head from below by means of their bent ends.
Claim 7
Dependent Claim
41 words
A handle mounting as claimed in claim 5, wherein the fork legs are cranked before the transition to the bent ends so that they bear on the back of the implement head by way of a portion parallel to the back.
