Description

Tool for cleaning surfaces

Technical Field

The present application relates to tools for cleaning surfaces such as floors, washable objects, walls, and the like.

Technical Field

A tool for cleaning a surface has a handle that operates a head. The operating head is stably coupled to an end of the handle and comprises a cleaning element capable of absorbing water and retaining dirt, and a support element supporting the cleaning element and connecting the cleaning element to the associated handle. These tools are also known as mops or squeegees. These cleaningThe element may be a cloth (also known as a wipe) and may be comprised of a fabric, nonwoven (also known as TNT). The cleaning element may also consist of a plurality of bands or braids of fabric or non-woven cloth which are stably fixed to the support element, the cleaning element producing the best results being made of microfibers. These tools enable the user to immerse the cleaning elements in the liquid without the operator directly contacting the liquid. To facilitate the flushing operation of the tool, the tool may also be marketed with a dedicated bucket (bucket) comprising wringers on the inside, on the top and on the sides for pressing the cleaning element by compression against the wringers at the very heart. Various attempts have been made to reduce the amount of labor of the operator in the wringing and cleaning operations and to improve the achievable cleanliness targets. For example, to facilitate wringing, water hoppers have been designed which can wring cleaning elements by acting on a pedal; the bucket carries an electrically powered device for wringing out the cleaning elements, and a rotatable handle using a rotator-based mechanism. The development of these products aims at solving some of the drawbacks that occur in daily cleaning operations, but is not the best solution to reduce the amount of labor during cleaning operations by improving task ergonomics. Fig. 1 and 2 relate to a known type of electric cleaning tool 101 having a handle 102 and an operating head 103, the operating head 103 being connected to the handle by a joint 104 in which a tank (not shown) of cleaning liquid 105 and a motor (not shown) are arranged. The head comprises two rotating discs 106 rotating in opposite directions, which are activated by a motor, to which two cleaning elements 107 are firmly fixed, i.e. two circular cloths 107 for cleaning a surface. During the cleaning operation, the cloth may press against the surface to be cleaned. The reservoir may spray cleaning liquid 105 through openings 108 onto the surface to be cleaned over which two cloths 107 will pass. The distal end of the handle has a grip 109 thereon. In order to wring out two cloths 107, the tool 101 must be used with a suitable water bucket 110 (see fig. 3) in which a plurality of idler wheels 111 are fixed, which are mounted perpendicularly to the rotation axis of the cloths, without having to disassemble the cloths. Unfortunately, such power tools are not effective for deep cleaning and disinfecting surfaces, particularly because of the presence of the wringerPreviously, two cloths 107 could not be easily rinsed without disassembling the head, and because the total surface area of the two cloths was very limited (disk diameter 15cm, only 353.25cm, although the tool size was large) ² ). This limitation is due to the strong friction of the rotating two cloths 107 against the surface to be cleaned, and also to the inability of the cloths to protrude from the rotating disc, as the disc is continuous, which if the cloths protrude, would prevent the disc from rotating. Mops (or squeegees) are distinguished from other tools for cleaning surfaces in which the cleaning elements are not capable of absorbing water and retaining dirt. These further tools can only be used to clean surfaces from dirt. In fact, it involves a further cleaning operation, typically manual, using a sponge or a water-absorbing cloth to absorb and retain the dirt detached from the surface. Fig. 4 shows a power tool 201 currently on the market. The other tool has a short handle 202 and an operating head 203, the operating head 203 being connected to the handle 202 by a joint 204 and ending in a brush 205, typically made of nylon. The motor is arranged in an operating head which is capable of rotating the brush, the motor having a low power level and running at a high number of revolutions, because the friction forces generated by the small brush on the surface to be cleaned when rotating are low. Tools are commonly used for smaller sized surfaces to be cleaned, such as sanitary products (bowls, bidets, etc.).

Disclosure of Invention

The main object of the present application is to eliminate the drawbacks with respect to the tool for cleaning surfaces of the present application, which comprises cleaning elements capable of absorbing water and retaining dirt, in particular made of microfibres. In particular, the main purpose is to ease the effort done by the operator during the cleaning step and to speed up the cleaning operation by minimizing the size of the tool. It is a further object of the present application to provide an efficient and ergonomic tool for cleaning surfaces, said tool having cleaning elements made of microfibers, which enables the use of simple known hoppers provided with wringers as described above for wringing out related cleaning elements.

These objects and aims are achieved by the tool for cleaning a surface according to the present application.

The first handle is effective against friction generated by the cleaning elements during rotation and the presence of a single cleaning element can increase its size while the contact surface of the operating head remains unchanged. In fact, the cleaning elements may advantageously extend far beyond the contact surface. The tool for cleaning a surface according to the application is capable of rotationally pulling a cleaning element over the surface to be cleaned, said cleaning element having a diameter of even up to 35cm and being greater than 960cm ² And the fact that due to the presence of the inclined first grip, it does not tend to rotate the handgrip. Thus, the cleaning operation is accelerated because the surface of the tool to be cleaned at one time is very large, in particular with respect to the known tool 101 shown in fig. 1 and 2.

The applicant has determined that in fact a cleaning tool having other characteristics similar to those of the claimed cleaning tool, but having a motor with a torque below 5Nm, will not be able to successfully rotate a cleaning tool having a torque of 150cm ² And the surface area of the microfiber cloth is equal to or greater than 300cm due to friction between portions of the cloth covering the contact surface ² . This friction also increases with the type of material of the cloth, in particular in the case of a material made of microfibres. Applicants have also verified the performance of a cleaning tool having other characteristics similar to the claimed cleaning tool (i.e., having a single contact surface), but not including a first handle. In this case, the handle will tend to rotate or be twisted against the friction force due to the friction force created by the rotating cloth portion. Thus, the tool is neither easy to use nor ergonomic. It is worth noting that the wringer can rinse the cloth in a bucket provided with the wringer described above, without having to disassemble it, as long as it has a larger bottom than the contact surface.

The present application enables individual replacement of the cloth when the cloth wears out and/or is too dirty to be reused. This is because the first housing and the blocking means are arranged in such a way that the cloth is reversibly fastened to the support and connection means.

Referring to fig. 32, reference numeral "12" denotes a tool for cleaning a surface according to the present application, including:

-an operating head 11, again comprising: surface cleaning agent made of microfibers with a surface area equal to or greater than 300cm ² A cloth 13 of (2); support and connection device 14, comprising: a first side 15, a second side 17 opposite to said first side 15; and a contact surface 16 equal to or greater than 150cm ² Is arranged on the first side 15; a first housing 18, provided on said first side 15, having a closed annular shape and which surrounds and is firmly constrained to said contact surface 16; a connecting element 21 arranged on the second side; and blocking means 22, wherein said first housing 18 and said blocking means 22 are configured in such a way as to reversibly insert said blocking means 22 into said first housing 18, said cloth 13 being unfolded and arranged between said first housing 18 and said blocking means 22 when on said first side 15 of said support and connection means 14, with the aim of reciprocally and reversibly fixing said cloth 13 to said support and connection means 14 by means of a friction coupling with a central portion 131 of said cloth 13 in contact with said contact surface 16;

-a handle 300, in turn comprising: a first handle element 302 having a first longitudinal axis 306, a second handle element 301 having a second longitudinal axis 305, wherein said first handle element 302 and said second handle element 301 are connected to each other at opposite first ends thereof, possibly adjusting the tilt of said second longitudinal axis 305 with respect to said first longitudinal axis 306;

-an electric motor comprising a shaft 307 and having a torque equal to or greater than 5Nm, said electric motor being housed in said first handle element 302, said shaft 307 being arranged substantially parallel to said first longitudinal axis 306, one end of said shaft 307 protruding from a second longitudinal end 308 of said first handle element 302 opposite to said first end of said shaft, wherein said end of said shaft 307 can be firmly fixed to said connecting element 21, once fixed, such that said contact surface 16 is arranged perpendicular to said shaft 307 and such that said contact surface 16 can be moved rotationally with respect to said shaft;

at least a first handle 310 fixable to said second handle element 301, substantially inclined with respect to said second longitudinal axis 305 and on the opposite side with respect to said first handle element 302, and once fixed, grippable to oppose said friction of said portion of said cloth 13 upon a rotational movement of said contact surface 16 about said axis 307.

In a preferred embodiment, the second longitudinal end 308 of the first handle element 302 comprises a first through hole (not shown) from which the shaft 307 protrudes, and a sealing gasket arranged at the first through hole around the shaft 307 to prevent liquid from entering the interior of the first handle element 302 through the first hole during flushing of the cloth 13, and wherein the first handle element 302/shaft 307 group is waterproof, at least in the range of 10cm-15cm (preferably 20 cm) from the first through hole, and preferably completely waterproof. To this end, the first handle element 302 may advantageously be formed as a single piece, preferably made of plastic. In this case, it can be immersed without problems in the water bucket up to the first handle element 302, with the aim of flushing the cloth and wringing it. The cleaning of the cloth may be done electrically in a water bucket, preventing direct contact of the user with a cleaning agent, such as hypochlorite, bleach or other detergents for cleaning. All of the foregoing can be accomplished due to the water-repellent nature.

To advantageously allow the first handle to be secured in a position suitable for left and right handed persons, the tool 12 for cleaning a surface according to the present application may further comprise: an annular element 311 configured to surround a lateral portion of the second handle element 301 and comprising a second threaded through hole 312, wherein the first handle 310 comprises a threaded element 313 operable to be screwed into the second threaded through hole 312 to secure the first handle 310 to the second handle element 301 when the annular element 311 surrounds the lateral portion of the second handle element 301.

Because the use of two hands for cleaning operations is more ergonomic, the tool 12 for cleaning surfaces according to the present application may include a second handle that may be secured, and preferably secured, to a second handle element. To counteract friction generated by the cloth during rotation, the ring element 311 may comprise a third threaded hole provided on the opposite side from the first threaded through hole 312, and a second handle 309, the second handle 309 comprising a further threaded element which is operable to be screwed into the third threaded hole, in order to fix the second handle 309 to the second handle element 301 when the ring element 311 surrounds the lateral portion of the second handle element 301, the second handle element 301 being substantially inclined with respect to the second longitudinal axis 305.

The term "substantially inclined" means an inclination angle between 5 ° and 175 °. The first grip, preferably and optionally, and the second grip, are inclined with respect to the second longitudinal axis 305 by an angle which is gradually preferably between 10 ° and 170 °, between 20 ° and 160 °, between 30 ° and 150 °, between 40 ° and 140 °, between 500 ° and 120 °, between 60 ° and 130 °, between 70 ° and 110 °, between 80 ° and 100 °, preferably an angle of about 90 °.

In a preferred embodiment, the second handle may also be formed integrally with the first handle, for example forming a handle or steering wheel fixable and preferably fixed to the second handle element 301.

The cloth may advantageously extend beyond the contact surface 16 and may have a length of between 400 and 1000cm ² Surface area therebetween. In this case, the torque of the motor is preferably between 10Nm and 25Nm, preferably between 12Nm and 20Nm, which corresponds to a torque between 70kg and 200 kg. Especially when the overall size of the cloth is 500-1000cm ² When, for example, if the cloth is of a diameter of about 1A circular shape of 5-35 cm.

In each of the embodiments described in this document, torque is in any case preferred, even if not explicitly mentioned. It is also gradually preferred that the torque of the motor is between 8 and 40Nm, between 10 and 35Nm, between 10 and 30Nm, between 10 and 25Nm, between 10 and 20Nm and between 10 and 15 Nm.

The rotational speed of the motor may vary between 60 and 350rpm and may be regulated by two buttons or potentiometers (not shown). This allows the use of low rotational speeds when the cloth is wet (e.g. during a floor cleaning operation or during flushing of the cloth in a water bucket) to avoid spraying. However, when the cloth is wet or dry, higher rotational speeds may be used, for example for polishing floors or lifting dust from floors. Therefore, it is preferred that the embodiment of the tool 12 for cleaning a surface 11 according to the application further comprises an adjustment means of the rotational speed of the shaft 307 of the motor, said adjustment means being functionally connected to the motor for changing the rotation speed of the drive shaft from 60rpm to 350rpm. The adjustment means may preferably be provided in the first handle element 302. Furthermore, the regulating device may advantageously be a potentiometer or an inverter.

In a preferred embodiment, a tool 12 for cleaning a surface according to the present application may comprise: a joint 312 having an axis of rotation disposed perpendicularly with respect to the first longitudinal axis 306 and with respect to the second longitudinal axis 305 connects the first ends of the first and second handle elements 302, 301 to one another. More preferably (see fig. 19), the first end of the first handle element 302 has a first upper abutment surface and a second upper abutment surface inclined with respect to each other, and the first end of the second handle element 302a has a third lower abutment surface and a fourth lower abutment surface inclined with respect to each other, wherein said joint 312 connects both ends of the first handle element 302 and the second handle element 301 such that it can be arranged in a first configuration, in which the first upper abutment surface abuts the third lower abutment surface (see fig. 19), a second configuration and in which the second upper abutment surface 320 and the fourth lower abutment surface 321 are inclined with respect to each other by an angle α, and wherein the first longitudinal axis 306 and the second longitudinal axis 305 coincide with each other or are in any case parallel to each other, and a plurality of intermediate configurations (preferably a limited number of configurations); in the second configuration, the second upper abutment surface 320 abuts the fourth lower abutment surface 321, wherein the first lower abutment surface and the third abutment surface are inclined with respect to each other by an angle α, and wherein the first longitudinal axis 306 and the second longitudinal axis 305 are inclined with respect to each other by an angle α; among the plurality of intermediate configurations, the intermediate configuration is located between the second configuration and the second configuration, and the channel from one configuration to another configuration is click-operated. For this purpose, a button 322 is included for blocking the arrangement at the joint 32. The angle is preferably 60-80 deg., so that the cleaning operation can be performed ergonomically without having to place the entire handle perpendicular to the surface to be cleaned. As an alternative to the joint, a toothed ring (toothed ring) may be used.

For transport to a point of sale, it is preferred that the second handle element 301 consists of a first lower member 304 and a second upper member 303, which may be joined end-to-end to be reversibly secured to each other. To this end, one of the members may comprise a button 401 that can be activated to disengage from each other when coupled by friction.

In order not to have to connect the motor to an electrical socket during a cleaning operation, the tool 12 for cleaning a surface according to the application preferably further comprises a rechargeable battery (not shown), preferably a lithium battery, which is arranged in the second handle element 301 and preferably in the first lower member 304 and which can be recharged through an opening 400 arranged in the second handle element 301 (see fig. 16 and 17).

The motor may be activated by a button 403 provided in the second handle element 301, preferably provided near the first handle 310. Thus, the first and second lower members 304, 303 may comprise electrical contacts 404, which are pre-arranged for connecting the push button 403 to the rechargeable battery, whereas the electrical connection between the first and second handle elements 301, 302 is not visible in the figures, but may pass through the joint 312.

Alternatively, the cloth 13 may be radially cut into strips 500 at opposed portions that are not in contact with the support and attachment device 14 (see FIG. 43).

The contact surface 16 is preferably continuous, as shown in the figures associated with the present application, but may also be a discontinuous surface.

In a preferred aspect of the application, the blocking means 22 is configured as an split ring (see fig. 44), a closed ring, a ring portion, portions of a ring. A split ring, more preferably circular, is preferred, but a closed ring may also be used when the closed ring is elastically deformable, and/or the first inner annular edge 19 of the first housing 18 comprises a plurality of terminal portions 80 or flanges, the plurality of terminal portions 80 or flanges being elastically deformable and capable of changing the circumference of the first inner annular edge 19 of the housing by relative elastic deformation.

The support and connection means 14 may be made in one piece or more preferably may comprise (see fig. 44): a support 23 having a first side 70 and a second side 71 (see fig. 38); the contact surface 16 and the first housing 18 are disposed on opposite first sides 70; a first coupling element 25; a connecting device 24 with a fixing element 21; and a second coupling element 26, which can be reversibly coupled to the first coupling element 25, in order to firmly fix the fixing element 21 to the contact surface 16. This simplifies the production of the support and connection device 14. The first coupling element 25 is advantageously a third peripheral edge 25 surrounding the first casing 18; the second coupling element 26 is a second housing 26 arranged on the opposite side with respect to the fixing element 21 and configured to be stably and reversibly coupled with the third peripheral edge 25 housing the supporting means 23, wherein the opposite second side 71 faces the second housing 26 and the contact surface 16 faces the second housing 26, the central portion of the cloth 13 being in contact with the surface to be cleaned when said operating head 11 is in contact with the surface to be cleaned. In other words, the second housing may have an opposing opening with the fourth edge 40, and the contact surface 16 will be substantially aligned with the fourth edge 40 or will protrude from the fourth edge 40.

In order to advantageously simplify the assembly operations of the operating head 11 of the present application, the second housing 26 is advantageously adapted to be stably and reversibly coupled with the third peripheral edge 25 by a friction coupling or screwing in, more preferably by a friction coupling. In the case of screwing in, the third peripheral edge 25 may be threaded, as may the annular inner wall of the second housing 26. Alternatively, additional fixing elements may be used to fix the support means 23 to the connection means 24, such as screws and threaded holes.

As shown in the drawings associated with the present application, it is preferable that the first housing 18 has a closed annular circular shape, and the blocking means is configured to: a circular or open triangular ring, a circular or closed triangular ring, a circular or triangular ring portion or portions of a circular or triangular ring.

Preferably the contact surface 16 extends between 150 and 255cm ² Between, preferably between 175 and 227cm ² Between and advantageously about 200cm ² . This is because in this way the force exerted by the user can be distributed over a larger contact surface, simplifying and accelerating the cleaning operation. Furthermore, these dimensions represent a good compromise between the floor surface in contact with the central portion of the cloth 13 and the possibility of wringing out the cloth in a suitable bucket. When the contact surface 16 is circular, it may have a diameter of 14-18cm, more preferably 15-17, advantageously 16cm. The central portion 131 of the cloth 13 preferably comprises at least two layers of fabric or nonwoven which are firmly constrained to each other in order to relieve the pressure that can be exerted on the contact surface 16 during the cleaning operation. In this way, delicate surfaces (e.g. parquet or marble) are better protected.

In order to simplify the assembly operations of the operating head, in particular when it is necessary to replace the cloth 13, a hand cone (bradawl) 30 (see fig. 44) may be used, which has a T-shaped handle 31 and a bar 32 fixable to the handle, said bar having opposite use ends of the cone shape, configured to push the blocking means 22 into the first housing 18 when the cloth 13 is unfolded and arranged between the first housing 18 and the blocking means 22 on the first side 15 of the supporting and connecting means 14.

In another particularly preferred aspect of the application, the cloth 13 is preferably made of polyester/polyamide microfibers, advantageously with a honeycomb structure.

It should be understood that the foregoing has been described by way of non-limiting example, and that technical functional variants are considered to fall within the scope of the application as claimed below.
