Handle for manual cleaning tools

Abstract

 The device comprises a resin connector(1) with a cylindrical seat(2) for retaining the end of a hollow metal handle(3) in order to cover and protect the end edge of the handle, the handle-end surrounding the axially extending central portion(4) of the connector which forms the inside wall of said cylindrical seat.

Description

[0001] The invention relates to a handle, in metal sheathed draw piece, for manual cleaning devices characterized by the fact that the lower terminal part is integrated in the screwing threaded part of the tool with a volute seat.

[0002] For cleaning operations in general and particularly for sweeping, washing, treating surface with different goods, for cleaning floors, walls, glass- walls or windows and other, manual devices of different kinds are currently used to steer by means of a stock handle. In general on the lower end of this cylindrical handle a larger diameter resin connector with outgetting screwed part is fitted by insertion for mounting the tool. Consequently the handle end, in a free approach, beats on the intermediate crown foreseen between the above axial part, which is embodied in the handle end, and the above mentioned screwed fitting part of the tool. This causes two inconveniences: an intrinsic structural fragility, since the means underlies to cutting strains, and causes a precarious binding of the cylindrical metal part to the resin connector, since the parts are freely coupled, which leads to handle break through wear or to release of the components owing to their deformation. Moreover, since the means uses a handle in sheathed metal profile, its beating disposition in a free approach on the said crown does not enable to cover imperfections and curling up of the covering sheath. These inconveniences are obviated by the system according to the invention which foresees a different connecting system for the handle, in sheathed metal profile to the mounting threaded part, which ensures a solidary working binding condition, by integrating these parts by embodying them, and carries out sealing of the sheath border covering the metal profile part of the handle.

[0003] Substantially the invention uses a resin joint 1 with a cylindric seat 2 for containing under pressure the handle end 3 in sheathed metal profile, which in an analogous way contains the cylindrical axial part 4 which forms the inside wall of the above cylindrical seat 2. This combined connecting system, through an integration of its components, determines a solidarily operating binding condition of the resin joint 1 with the handle in sheathed metal profile 3 and covers and protects the covering sheath.

[0004] An execution form of the invention is illustrated in a merely indicative way in the drawings of Table 1. With reference to this table, fig. 1 is the view in longitudinal section of the handle end part with a tool 5 fitted on it. The double clutch integration of the joint 1 can be seen with handle 3 and the mounting condition on handle of the tool 5 carried out by screwing the threaded part of the joint 1 in its volute seat 6. Fig. 2 is the perspective section view of the handle end with components 1 and 3. Fig. 3 is the partial view of a possible cleaning tool, with a dashed view of its handle 3 which penetrates into joint 1, whereas its axial part of the joint penetrates into the same handle.

[0005] In the realization, the components, their shape, the material and anything else may be foreseen in different ways according to the use requirements.

Claims

1. Handle for manual cleaning tools, characterized by the fact that a resin joint (1) is used with a cylindrical seat (2) for containing under pressure the handle end (3), in sheathed metal profile, which in an analogous way contains the cylindrical axial part (4) forming the inside part of the said cylindrical seat (2). This combined dutch system, by integration of the components, determines a solidarily operating binding condition of the resin joint (1) with the handle (3), in sheathed metal profile, and covers and protects the covering sheath on border.
