10 cleaning tool, in particular suitable for cleaning floors and other surfaces comprising cleaning rollers which are operated by a gear mechanism with turn conversion, which is driven by a single wheel motor

fifteen

BACKGROUND OF THE INVENTION

Currently in the market for household goods there different utensils for cleaning floors and other surfaces, such as brooms, vacuum cleaners and others. The brooms

20 have the disadvantage that they require the action of sweeping, drag the dirt to a certain point and finally They require an additional collector to collect dirt. The mops do not require the action of sweeping and at first neither they require an additional collector since the dirt remains

25 hooked on the mop itself, but the use of this device is

limited to interior surfaces (tiles, parquets, etc.) and for a very specific dirt (mainly dust and hairs).

A household vacuum cleaner is characterized by having as at least one mouth that is in contact with the surface to clean there are basically two types of mouths, the mouth with retractable filaments for use in tiles, carpets and any surface in general, and the mouth of fixed filaments for use on delicate surfaces such as parkets and certain types of tiles.

In both mouths manufacturers must enable small filament wall openings to allow entry of the dirt. This design reduces the efficiency of the vacuum cleaner by have the following inconveniences:

-The suction of the vacuum cleaner is limited by the own

wall of filaments that only allow air flow

circulate through the small openings

-The filaments themselves eject the particles out

when traveling on the surface to be cleaned.

On the other hand, crumbs that have rollers, base their operation on the collection of crumbs by bottom of the device, having as main inconvenient that it is very easy for the collected particles get out of it again for not being able to implement any system roll that isolates the dirt from the roller.

In the state of the art there are a variety of utensils based on rollers or barbed brushes intended to collect the dirt on the ground or surface.

Examples of this type of utensils are described in the Patent Nos. US4007508, US2004034952 and ES0286283. However, the device represented in US Patent No. US4007508 It presents a certain complexity by requiring four wheels tractors (motor) to force the direction of rotation of the rollers (instead of just one). At the same time, the existence of these four wheel drive limits freedom of movement on the surface to be cleaned in exclusively straight directions preventing curves and therefore easily move the device in any desired direction. This finally forces to lift the device off the floor and redirect it to use it In a new direction.

Patent No. US2004034952 is also known in which describes a cleaning tool provided with a mechanism of gear (very similar to the US4007508 patent but simplified) which acts in such a way that when the utensil forward the associated roller rotates picking up the dirt. However, if the user moves in the opposite direction (backwards) the tool, the gear mechanism does not act by what the roller does not collect dirt and only allows work one way (forward). Finally the patent ES0286283 also has the disadvantage that it only acts in

one way and therefore only works by moving the device forward.

DESCRIPTION OF THE INVENTION

The present invention consists of a cleaning tool which has two parallel rotating main rollers between yes they turn in opposite directions towards the interior of the utensil. This allows dirt to be trapped between both rollers and peel off at the top of the rollers by uncoupling of the filaments of both rollers, the centrifugal force of the rollers and the combing of the filaments inside the utensil.

Additionally, this tool has a mechanism for turn conversion that is driven through a single wheel motor in contact with the surface to be cleaned and allowing the rollers always turn in the same direction of rotation, regardless of the direction of rotation of the driving wheel. Finally the device consists of a second wheel or wheel displacement, in contact with the surface and independent of the driving wheel, which allows the device to be orient in any direction without lifting it from ground. With this arrangement of the wheels, the utensil can move across the surface to any direction, allowing both main rollers always turn in the same direction of rotation regardless of the direction

of use of the utensil on the selected direction, both towards Forward as backward.

The present invention has been developed for the purpose of provide a cleaning tool that solves the existing problems in the state of the art, contributing in addition other additional advantages, depending on the embodiment concrete, which will be evident from the description that accompanies next.

It is therefore an object of the present invention. provide a cleaning tool, particularly suitable for cleaning of floors and other surfaces that has a means of cleaning operated by a gear mechanism with conversion rotation.

In particular, the invention relates to means of cleaning that consist of two main filament rollers

or similar, rotating parallel to each other and located inside of a cavity of an internally hollow housing, which they rotate in opposite directions to each other. In addition, the mechanism of gear with turn conversion is driven by a single wheel motor capable of coming into contact with the surface to be cleaned, which is associated with the main axis that transmits the movement of rotation to the two main rollers through axles associated to each of the main rollers, thanks to the turn conversion mechanism and that allows the main rollers always turn in the same direction of rotation, regardless of the direction of rotation of the driving wheel,

sweeping dirt particles into the device.

On both main rollers a hairstyle is performed on the inside the device in order to help remove the dirt particles from the filaments of the rollers and from this way to improve the cleaning efficiency of the device.

The device has a second wheel, or wheel of displacement in contact with the surface and independent of the drive wheel, which allows the device to be oriented towards any direction of use in a much more effective way and simple and without the need to lift it from the ground or surface, to redirect it.

In relation to the gear mechanism with conversion of turn, the main axis of said mechanism has a body elongate of substantially circular section, except a section of non-circular section, on which a central wheel is coupled movable on said non-circular section and turning in solidarity with the main axle, in which the central wheel is delimited by a first and second bounding wheel which in turn are mounted on the main axis by the section of circular section, turning freely on said main axis, the wheel being central and alternatively coupled bounding wheels each other, so that the bounding wheels and the axle main are able to rotate in the same direction of rotation or in opposite senses.

In addition, preferably the central wheel consists of a wheel with a non-cylindrical shaft with a cross section equal to the section of the non-circular section of the main axis, comprising on both surfaces of their faces at least one toothed crown concentric with respect to the non-cylindrical axis of the wheel and where Each crown is formed by a plurality of teeth.

It is worth mentioning that this cleaning tool does not require no electrical device for its operation, being by it completely mechanical so that it is not necessary to use batteries or power supply means nor of a maintenance.

As discussed the driving wheel and the wheel of displacement are independent of each other, allowing the orientation of the device towards any direction of use, the which, in a preferred embodiment, where maximum is achieved device operating efficiency, corresponds to the direction perpendicular to the axes of the main rollers.

To further ensure that the device can be move, not just orient, in any direction you could make a wheel variant as described in continuation.

The utensil can comprise a driving wheel capable of turning with respect to a main axis, including a plurality of second wheels radially arranged and protruding from the edge of the driving wheel body, in which the second wheels rotate

freely with respect to respective secondary axes of rotation perpendicular to the main axis of the driving wheel.

In this way it is allowed to move the driving wheel in any direction as it will rotate in a particular direction, but at the same time thanks to the radial wheels will be allowed move it over the surface.

The scroll wheel must also be multidirectional to make the entire utensil multidirectional, but in this case since this wheel is not the driving wheel, it can have the same provision as the one mentioned above or may have any other multidirectional wheel arrangement.

In this way, it is possible to have a utensil multidirectional that allows to remain effective in a wide range of different directions (and in both directions of the direction) to the perpendicular of the roller shafts main (ideal direction of use) reaching the extreme of yes the device will move in a direction parallel to the axes of the main rollers, the utensil would move without problem, the main rollers would not turn and the utensil It would act like a broom.

According to another aspect of the invention, the housing is defined by side walls and an upper base, including the inside the housing an interior separation wall and a base lower that would form a storage area or container of particles. This particle container would not be necessary for the concrete realization of mouths of vacuum cleaners since in

in this case the dirt would be sucked from the top of the device.

Advantageously, the storage area includes means of retention in an area near the entrance of the zone of storage that reduces the passage section. In this way, it prevents that in the case of rotating or turning the utensil, the particles and dirt generally accumulated in the area of storage, get out of it.

Preferably, the retention means consist of a section of wall that can present an inclination with respect to the horizontal plane in a downward direction when the utensil is arranged in a condition of use, such that it it makes it difficult for dirt to come out and at the same time it facilitates Dirt drop in storage area. In one embodiment preferred of the invention, this wall section is the one additionally performs the roller hairstyle to help remove dirt and move along the inclined wall towards the storage area, constituting the styling means.

In an alternative embodiment, the retention means they have a second wall inclined downwards located on the opposite side wall and at a different height so that define a zigzag route to the area of storage making it more difficult to exit the dirt in case of overturning of the utensil.

Another inconvenience to overcome in this type of devices is to allow localized dirt collection

at any point on the surface of the utensil outside the reach of the main rollers (for example under the mechanism or wheels) and allow dirt to be collected located between the limits of the utensil and the rollers, as per For example, collect dirt located near a baseboard where main rollers do not arrive and the device cannot displace more by being limited by the socket itself.

In a preferred embodiment and to solve the problem above, the axes of the main rollers or secondary axes could include toothed crowns that mesh with toothed crowns coupled to filament rollers or similar, secondary, which they rotate in the opposite direction to the associated main roller, such that The end of each rotating main roller is linked to a filament roller or similar secondary, adopting said filament rollers a substantially shaped configuration "X" in a horizontal plane, such that they are arranged on the part outside of the housing cavity.

The presence of secondary rollers favors that dirt particles, etc., when the utensil is moved in one direction, be moved towards the central part of the utensil, which corresponds to the area where the two rotating main rollers responsible for collecting particles

Thanks to all the previous technical characteristics, it obtains a cleaning tool provided with a mechanism gear with turn conversion, which is only used

a single driving wheel for driving said mechanism of gear and with this, of the multiple cleaning elements, by which is constructively much simpler, more effective in cleanliness and much more maneuverable with respect to utensils known in the prior art.

Throughout the description and claims, the word "understands" and its variants do not intend to exclude other technical characteristics or components. For experts in the matter, other objects, advantages and characteristics of the invention they will come off in part from the description and in part from the practice of the invention.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The present application refers to a cleaning tool for floors and other surfaces. The object of the invention according to claims 1-2 is a cleaning tool comprising two filament rollers that rotate in opposite directions by the action of a single driving wheel. The transmission of said movement is carried out through a rotation conversion mechanism, the direction of rotation of the rollers being maintained independently of that of the driving wheel. This conversion mechanism is constituted by a main axis, which rotates in both directions, and which has a non-circular section on which a central wheel with a non-cylindrical axis that rotates in solidarity with it and is delimited with free displacement. two wheels that rotate freely on the main axle in its circular section sections, with which it is alternately coupled each time the direction of rotation of the main axle changes through toothed crowns. The tool also has a freewheel wheel located in the housing opposite the drive wheel. These technical characteristics are already known from document D01 which describes this gear mechanism for turning conversion and its application to the construction of two-roller cleaning utensils in which the direction of rotation thereof remains unchanged (column 1, lines 3 -16; column 1, lines 44-53, column 2, lines 43-59; column 3, line 43 - column 6, line 29; figures). Therefore, the object of the invention according to claims 1-2 is not new. The design features of dependent claims 5-7 and 9, which refer to the existence of a storage area with retaining means, in the form of an inclined wall, which reduce the passage section and a section of wall entering contact with the filaments, are widely known in the state of the art (see documents D02 to D05) and therefore obvious to the person skilled in the art, which is why they are not considered to involve inventive activity. Finally, none of the aforementioned documents or any relevant combination thereof reveals a cleaning tool comprising two rollers that rotate in opposite directions by the action of a driving wheel and a turning conversion mechanism, which includes a plurality of wheels. radially distributed around the driving wheel, a series of secondary filament rollers located on the outside of the x-shaped housing or retaining means located different from the heights, defining a z-gz zag pr evor storage space . Accordingly, claims 3-4 and 8 are new and are considered to involve inventive activity. State of the Art Report Page 4/4
