DESCRIPTION

Plate for a surface cleaning tool

The present invention relates to household cleaning tools and in particular refers to a new improved type of support or plate for brooms, brushes, scrub brushes and tools in general for cleaning floors and surfaces.

Useful for cleaning floors, i.e. brooms, brushes, scrub brushes, cloth sweepers, etc. are known. These tools are generally provided with a handle that is suitable for the user to hold, to one end of which a support or plate is attached removably or permanently, the bristles of the broom or brush, or a cleaning cloth or Dust cloth, directly or indirectly attached to said support or plate.

Usually, the upper surface of the support or plate is provided with at least one coupling means for said end of the handle.

Said support or plate may also comprise coupling means for a cleaning cloth or a dust cloth.

Supports or plates are known in which the handle coupling means comprise a seat created in the upper part of the support, the inside of said seat being threaded or provided with projections or recesses suitable for engaging the end of the handle.

The supports provided with an internally threaded seat are suitable to be coupled to a handle having a correspondingly threaded end that can be screwed into the seat to achieve a rigid connection between the handle and the support.

On the other hand, the supports provided with a seat with coupling elements are suitable for coupling with a handle whose lower end is provided with corresponding elements capable of fitting removably in said seat.

Said seat, whose interior may be threaded or provided with coupling means, may be formed within the thickness of the support, then being lowered, or it may be formed in a sleeve protruding from the support.

Said sleeve is 2-3 cm long, so that the handle is inserted therein and screwed into a corresponding length of 2-3 cm.

Especially in the case of internally threaded sleeves, it often happens that the sleeve on which the handle rests tends to widen due to prolonged use, thus loosening the connection between the handle and the support.

Consequently, the handle gradually unscrews during use, until it comes out.

At this point, the user needs to repeatedly screw the handle or buy a new support.

Another drawback posed by known supports is that the sleeve is frequently broken due to prolonged use, as a result of the force applied to the sleeve itself by the handle, which makes it more difficult to properly grip the handle.

Document US4541139 refers to a broom holder consisting of several pieces, which includes a broom cover housing, suitable to be attached to the handle, a block of bristles to house the bristles, and a closing lid. Said broom cover housing comprises a neck member for inserting the handle, with an external part and an internal part, and wherein the lower part of said internal part comprises a threaded internal section suitable to allow the threaded end to be screwed thereon. of mango

Document US4684283 refers to a broom holder that has a cylindrical seat where a plug adapter is inserted. Said plug adapter is configured to hook a shaft.

Document US4384383 refers to a block with an upper part provided with a substantially cylindrical bore, the lower part of which has a reduced diameter and is threaded to allow the threaded end of the shaft to be screwed inside.

In order to overcome the aforementioned drawbacks, a new improved support has been designed and built, which is suitable for use with brooms, brushes, scrub brushes or tools in general for cleaning floors and surfaces.

The main object of the present invention is to guarantee a more stable connection between the handle and the support.

It is another object of the present invention to provide a support with prolonged duration.

It is a further object of the present invention to provide a support that can also be used in case of partial rupture of the sleeve.

These and other direct and complementary objects are achieved with the new improved support for brooms, brushes, scrub brushes or tools in general for cleaning floors and surfaces.

The invention consists of a support or plate for brooms, brushes, scrub brushes or tools generally for cleaning floors and surfaces as in claim 1, comprising a body to which it is possible to directly or indirectly hold the bristles of a broom or brush , and / or cloths for cleaning floors, as well as a sleeve or tube attached to said body and provided with coupling means for connecting a handle, and wherein the interior of said tube is generically subdivided into at least a first part, or part of engagement, in which said engagement means are arranged to connect the handle, and at least a second part, or extension, near the open end of the tube and without said attachment means.

More specifically, the new support or plate comprises a body whose lower face is suitable to be oriented towards the surface to be cleaned, wherein said lower face can be provided with broom or brush bristles or cloths in general for cleaning floors.

Said support or plate comprises at least one sleeve or tube for connecting the handle, located substantially in its upper or lateral part.

Said tube in turn comprises a cylindrical surface attached at one end to the body of said plate, while the opposite end is open to allow insertion of the connecting end of the handle.

Said tube is attached to said plate body so that it is substantially vertical or inclined, with its open end substantially oriented upwards.

Said tube is internally provided with preferably removable coupling means, suitable for engaging with said end of the handle.

Said engagement means comprise, for example, a thread suitable for receiving the correspondingly threaded end of the handle that is screwed thereon.

As an alternative to said thread, the interior of the tube can be provided with recesses or projections or other means for coupling the correspondingly configured end of the handle.

In the preferred solution, said thread and / or said engagement means for connecting the end of the handle are located within the tube only in one part of the tube, or part of engagement, near the end fixed to the body of the support or plate, while the remaining part, or extension, is not provided with said coupling elements.

Said extension, which preferably is 2-10 cm long, has the function of increasing the resistance of the tube and the maneuverability of the cleaning tool.

In particular, once inserted into the tube and held therein, the handle rests during use on the edge of the open end of the tube, said edge being separated from the point where the handle is connected to the tube.

This protects the handle connection area, which also ensures a more stable connection between the tube and the handle.

According to the invention, at the level of or in the vicinity of said upper end of the tube, one or more joints or reinforcement elements can be arranged, for example with an annular shape and suitable for being interposed between the cylindrical wall of the tube and the handle.

Said seals or reinforcement elements also have the function of preventing dirt from entering the tube. In addition to the above, said seals or reinforcing elements also have the function of preventing the handle from coming out.

According to the invention, at the level of or in the vicinity of the open end of the tube, the cylindrical wall of the tube may comprise at least a thicker part or reinforcement flange, preferably with an annular shape and facing outwards.

According to the invention, the new support can also comprise at least one substantially annular joint with a substantially cylindrical internal wall and an external wall at least partially in the form of a truncated cone, said annular joint being suitable for fitting on the handle to be insert into the tube, and where the insert and screw the handle make the gasket insert, which ensures a firm connection between handle and tube.

In the following description the characteristics of the new support or plate are highlighted, referring to the attached drawings that are attached by way of non-limiting example.
