Cleaning tool with hardened tip, especially for screw holes on robotic lawnmowers.

Abstract

Cleaning tool, characterized in that it comprises a carrier body (1) and a hardened metal tip (2) attached to the carrier body, wherein the tool is intended for removing dirt from screw receptacles, in particular on robotic lawnmowers.

Description

Technical field

[0001] The invention relates to a cleaning tool for removing dirt and deposits from screw sockets, particularly on robotic lawnmowers. The tool is specifically designed for applications where screw contamination by clippings, impurities, and dirt can impede the function or replacement of components. State of the art

[0002] In the field of robotic lawnmowers, a few maintenance and cleaning tools are known. For the targeted cleaning of screw holes – for example, for attaching blades or housing parts – improvised tools such as screwdrivers are predominantly used. Object of the invention

[0003] The object of the invention is to provide a cleaning tool that enables targeted, reliable and permanent cleaning of screw receptacles. Solution

[0004] The task is accomplished by a cleaning tool ( Fig. 1) solved. The tool comprises a carrier body (1) made of plastic - preferably producible by additive manufacturing - and a firmly integrated, hardened metal tip (2).

[0005] The metal tip is dimensionally stable, resistant to deformation, and allows for the precise removal of even hardened or dried-on deposits from screw receptacles. The connection to the plastic base is achieved through a form-fit, force-fit, or overmolding mechanism.

[0006] The carrier body can also be provided with a non-slip surface structure, such as knurling or texturing, to improve grip and handling during cleaning.

[0007] This representation ( Fig. 1) corresponds to a preferred embodiment of the invention.

Claims

[1] Cleaning tool, characterized by , comprising a carrier body (1) and a hardened metal tip (2) attached to the carrier body, wherein the tool is intended for removing dirt from screw receptacles, particularly on robotic lawnmowers. [2] Cleaning tool according to claim 1, characterized by , that the metal tip (2) tapers to a point to allow access to narrow recesses. [3] Cleaning tool according to any one of the preceding claims, characterized by , that the carrier body (1) is manufactured using injection molding or additive manufacturing processes. [4] Cleaning tool according to any one of the preceding claims, characterized by , that the metal tip (2) is inserted into a corresponding recess in the carrier body and held in a form-fitting manner. [5] Cleaning tool according to any one of the preceding claims, characterized by, that the connection between metal tip (2) and carrier body (1) is additionally reinforced by gluing as a material bond, overmolding as a form bond or welding as a material bond. [6] Cleaning tool according to any one of the preceding claims, characterized by , that the carrier body (1) is ergonomically shaped and has a non-slip surface. [7] Cleaning tool according to any one of the preceding claims, characterized by that the tool is designed as part of a modular maintenance kit for robotic lawnmowers. [8] Cleaning tool according to any one of the preceding claims, characterized by , that the metal tip (2) is made of hardened steel, stainless steel or a wear-resistant metal. [9] Cleaning tool according to any one of the preceding claims, characterized by , that the anti-slip surface on the support body (1) has a knurling, a texturing or a rubberized coating.
