Abstract

An operating handle (1) for devices, particularly for cleaning devices, such as wiping devices, mops, brooms, or the like. The operating handle (1) has at least a first and a second tubular handle element (2, 2′) which are able to be joined to one another. The tubular handle elements (2, 2′) form a hollow space (5). A connecting link (4, 4′) is provided for connecting the first and the second handle element (2, 2′). The connecting link (4, 4′) extends at least partially into the hollow space (5) formed by the handle elements (2, 2′). A first connecting segment (6) and a second connecting segment (7) are provided. The first connecting segment (6) is designed to connect to the first handle element (2), and the second connecting segment (7) is designed to connect to the second handle element (2′). The first and/or second connecting segment (6, 7) has a screw-in thread (11, 11′) which is forced into engagement with connecting agents (8) arranged on the first and/or second handle element (2, 2′). The first and/or second connecting segment (6, 7) has a supporting surface (9, 9′) for resting against the inner surface (10) of the handle element (2, 2′). The screw-in thread (11, 11′) is arranged in the region of the supporting surface (9, 9′).

Claims

1. An operating handle (1) for devices, particularly for cleaning devices, the operating handle comprising:

a first and a second tubular handle element which are able to be joined to one another, the tubular handle elements forming a hollow space;

a connecting link for connecting the first and the second handle element, the connecting link extending at least partially into the hollow space formed by the handle elements, the connecting link having a first connecting segment and a second connecting segment, the first connecting segment being designed to connect to the first handle element and the second connecting segment having being designed to connect to the second handle element and the first and/or second connecting segment having a screw-in thread which is forced into engagement with connecting agents arranged on the first and/or second handle element, the first and/or second connecting segment having a supporting surface for resting against an inner surface of the handle element and the screw-in thread being arranged in the region of the supporting surface.

2. The operating handle according to claim 1, wherein the connecting agents are designed as at least one projection that protrudes into the hollow space formed by the rod elements.

3. The operating handle according to claim 1, wherein the connecting agents are designed as at least two projections that are arranged on an imaginary, spiral connecting line.

4. The operating handle according to claim 2, wherein the projections are produced through a point-by-point deformation of the handle element.

5. The operating handle according to claim 1, wherein the projections are produced through a point-by-point deformation of the handle element.

6. The operating handle according to claim 1, wherein the tubular handle element is made of metal.

7. The operating handle according to claim 1, wherein a flange which projects beyond the supporting surface from the first and/or second connecting segment is provided at the connecting link in the region between the first and the second connecting segments.

8. The operating handle according to claim 1, wherein the connecting segments have an essentially cylindrical design.

9. The operating handle according to claim 1, wherein the connecting link is hollow.

10. The operating handle according to claim 1, wherein the connecting link is made of plastic.

11. The operating handle according to claim 10, wherein the plastic is polyamide.

12. The operating handle according to claim 1, wherein the connecting link only has a thread in the region of the first connecting segment, and wherein the supporting surface is formed as a cylinder in the region of the second connecting segment.
