The invention relates to an improved modular handle (1), particularly for brooms and like, characterised in that it is comprised of a plurality of handle parts or segments (2, 3, 4), and particularly at least a initial part (2) or grasping segment and at a support part (3) or segment for the tool to be handled, said handle parts or segments (2, 3, 4) being provided with a male end (5) and/or a female end (13), coupling each other by a forced introduction, said male end (5) providing at least a reduced diameter zone (6) with a undulate section, the perimeter of which is equal to the circumference of the handle, said section being obtained by deformation of the end of the part or segment of the same handle, and said female end (13) having an inner diameter to receive, by a forced coupling, said undulate section male end (5).
Improved modular handle, particularly for brooms and like, characterised in that it is comprised of a plurality of handle parts or segments, and particularly at least a initial part or grasping segment and at least a finale part or segment for coupling the tool to be handled, said handle parts or segments being provided with a male end and/or a female end, coupling each other by a forced introduction, said male end providing at least a reduced diameter zone with a undulate section, the diameter of which is equal to the circumference of the handle, said section being obtained by deformation of the end of the part or segment of the same handle, and said female end having an inner diameter to receive, by a forced coupling, said undulate section male end.
Improved modular handle according to one of the preceding claims, characterised in that said reduced diameter section of the male end has shape and dimension slightly growing or slightly conical.
Improved modular handle according to one of the preceding claims, characterised in that said undulate section male end is realised making the end passing the end of the part or segment within an apparatus provided with various shaped rolls, provided a dial and having the rotation axis laying on a plane perpendicular to the axis of the part or segment.
Improved modular handle according to one of the preceding claims, characterised in that it is realised employing bare tubes, or tubes coated with a plastic film, or painted tubes, or in any case tubes having a surface finishing not damaged by the diameter reduction step, this not involving a lengthening or compression of the material.
Improved modular handle according to one of the preceding claims, characterised in that said female end is protected by a ring partially inserted on the same in such a way that the terminal part of the tube is within the same ring, said ring possibly providing a groove to house an outward riveting necessary to promote the insertion of the male end and that could be realised by a suitable punch after the mounting of the ring.
Improved modular handle according to one of the preceding claims, characterised in that said ring for the protection of the female end has a very thin thickness and rounded shape so as to create the minimum discontinuity on the assembled handle.
Improved modular handle, particularly for brooms and like according to each one of the preceding claims, substantially as illustrated and described.
