Device comprising an articulated handle with specific housing on broom or brush or other implement with multi angular positioning about two orthogonal axes

Description

Field of the invention

[0001] The present invention generally relates to a device of the type comprising a handle for the use of broom or brush or other implement, herein named broom, and more particularly to the handles providing the possibility to set the broom at different angular positions in relation to the handle.

Background of the invention

[0002] The prior art discloses articulated handles connected by different kind of hinges to a broom with the purpose to change the inclination of the broom and keep a good sweeping position in particular when sweeping under furniture. Most of them provide this skill by means of an hinged joint between the handle and the broom pivoting about only one axis with the possibility to lock the broom.

[0003] The state of the art also include some other devices combining two different rotations of the broom about two orthogonal axes with the possibility to lock the broom for the purpose to increase the said sweeping effect and the manoeuvrability of the device.

[0004] The devices disclosed by documents EP 0 430 846 A1 - 05-06-1991, us 1 687 953 A - 16-10-1928, US 4 893 370 A - 16-01-1990, comprise an articulated handle for cleaning implements with a locking device of two different rotation of the implement on two axes.

[0005] Although the improvement disclosed in said prior art, however it is possible to note a limited number of angular positions of said implements or a not user friendly activation of the locking device or the presence of a not functional size in proximity of the hinge.

Summary of the invention

[0006] The purpose of the present invention is to solve said problems improving a manual working device, in particular a cleaning device, and more specifically a broom, having an higher possibility of articulation of the handle and the broom as to maximize the operational flexibility.

[0007] The present invention disclose an articulated handle connected by a hinge to a broom or brush or other implement, herein named brown, comprising a first spring locking and unlocking device inside the handle, activated by means of a knob or similar along the handle, which allows the rotation of the broom up to 180°, by gravity or by hand, around the axis of the pivotal connection between the handle and the hinge, and also allows the locking of the broom at multiple predefined angular positions.

[0008] Furthermore it comprises a second spring locking and unlocking device inside the hinge, activated by means of two buttons on both lateral sides of the hinge, which allows the rotation of the broom up to 360°, by hand, around the central rotational axis of the connection between the hinge and a specific housing on the broom-back, and also allows the locking of the broom at different predefined angular positions.

[0009] Both said axes are orthogonal.

[0010] Furthermore said second spring locking and unlocking device inside the hinge allows the fastening and unfastening of the hinge on the broom-back, so that it is possible to use the handle with another kind of broom or implement having the same said housing.

[0011] Each angular position of the broom around one rotation axis can be combined with each angular position around the other axis.

[0012] It is the object of the invention to provide:

• a more efficient cleaning effect: for example when sweeping under domestic or industrial furniture, where it is possible for the operator to choose the better sweeping inclination on the flpor and the better orientation of the handle in respect to his position;
• more contexts of use: the wide possibility of articulation allows, for example, to sweep on walls, inclined surfaces, ceilings, shelves, cars, camper, equipments, shutters, tents and so on;
• an effective flexibility: the rapidity of the activation of the locking devices which allows to change constantly the operational setting, it is for example another skill the rapid unfastening of the broom and its manual use;
• a multi tasking device: it is possible to use different implements with one handle;
• an easy transport device: unfastening the broom, for example, it is easier to put it on a car;
• a less cumbersome device/a compact device: it is possible choosing the best inclination when putting back or unfastening the broom.
