Definitions
- the invention relates to a cleaning device according to the preamble of claim 1 .
- Cleaning devices for floor cleaning which comprise a main body made of foam are known from the prior art.
- the main body is advantageously capable of soaking up liquid and delivering it to a floor surface to be cleaned.
- a main body of this type can also be easily wrung out and thereby emptied of water.
- a main body made of foam which is not filled with liquid can absorb a liquid film from a floor surface by virtue of capillary action.
- the object of the invention is therefore to design and develop a cleaning device of the type described in the introductory section such that it has an abrasive surface that can also be used to reliably collect both liquid and hair and dirt particles.
- a cleaning device for cleaning surfaces, particularly for floor cleaning, comprises a main body made of foam.
- flocked material is allocated to the main body, with the flocked material being arranged on a surface of the main body that can be turned to face a floor surface to be cleaned.
- the invention utilizes the knowledge that flocked material has relatively hard and resilient fibers which can have an abrasive effect.
- the flocked material can be used to remove stubborn dirt from a floor surface.
- a suitable arrangement of the flocked material can ensure that hair, crumbs and/or dirt particles will be collected by the flocked material.
- the invention utilizes the knowledge that the flocked material can give a relatively soft main body made of foam an abrasive character. Specifically, it is acknowledged that the advantages of the foam, namely the water storage capacity thereof, can be combined with the advantages of a hard surface, namely the flocked material.
- the flocking is applied to a standard wiping surface, the user can apply the flocked regions easily and without assuming anatomically uncomfortable contact angles in order to remove dirt.
- the lifespan of the flocking is adapted to the lifespan of the foam, so that when the foam is replaced, the original, good-as-new cleaning capacity can again be achieved.
- the flocking is applied to the flexible foam. As a result, when the cleaning device is rinsed with water the fibers of the flocked material are more thoroughly cleaned, since they are able to move relative to one another.
- a cleaning device which attains the above-stated object is thereby provided.
- the flocked material could be arranged in an insular manner and/or isolated in regions on the surface in such a way that the surface is not completely covered by flocked material.
- the insular arrangement ensures that channels and/or interstices are created between individual islands of flocked material. Hairs and particles of dirt can be easily collected and removed within these channels or interstices.
- the isolated arrangement of flocked material in regions on the surface ensures that a sufficient amount of the surface is not covered by flocked material.
- the part of the surface not covered by flocked material is available for absorbing liquid from a floor surface and/or for delivering liquid to the floor surface.
- the flocked material could comprise fibers and an adhesive matrix, wherein the fibers are injected into the adhesive matrix such that unattached ends of the fibers project outward from the adhesive matrix.

- the unattached ends of the fibers can be moved like a brush over a floor surface.
- the flocked material could comprise fibers having a thickness ranging from 20 to 100 decitex (dtex). Unexpectedly, it has been found that fibers of this thickness are stiff enough to have an abrasive effect, while being fine enough for small particles of dirt to collect among them, in the manner of a comb.
- the flocked material could comprise fibers having an extension length of 1 to 3 mm.
- the extension length is understood as the region of a fiber that is not encompassed within the adhesive matrix.
- An extension length of 1 to 3 mm ensures that the fibers are sufficiently flexible, but are also sufficiently hard and rough.
- the flocked material could be arranged directly on the main body made of foam.
- the adhesive matrix is arranged directly on the main body.
- the surface of the foam is covered only by the adhesive matrices. All other regions of the surface of the foam are available for absorbing and/or delivering liquid.
- the flocked material could be arranged on a layer which is attached to the main body made of foam. It is therefore specifically possible for fleece or non-woven fabric to be laminated to the main body.
- the flocked material can be easily applied in a specific pattern to the layer, in a separate production step.
- Complex patterns of flocked material can thereby be easily arranged on a main body having curved surfaces.
- a gripping or holding means could be arranged on the main body.
- the gripping or holding means allows the cleaning device to be easily gripped manually.

- the flocked material could be designed as an elongated edge which extends along a scrubbing edge of the main body which can be turned to face the floor surface to be cleaned.
- the elongated edge forms an isolated region of flocked material on the surface of the main body. This specific embodiment allows stubborn dirt to be removed using the scrubbing edge of the main body, while a liquid film can be absorbed from the floor surface using an edge that faces away from the scrubbing edge.
- a set could comprise a cleaning device of the type described herein and a dustpan, wherein the dustpan is equipped with flocked material.
- a main body made of foam can be wiped off on the inner side walls of the dustpan. This allows the flocked material to remove hairs and/or dirt particles from the main body and collect them.
- flocked material is produced by injecting fibers into an adhesive matrix. More specifically, the fibers are injected electrostatically into an adhesive, wherein the fibers are preferably 22 dtex, 50 dtex or 100 dtex fibers.
- the dustpan could have a supporting edge on which flocked material is arranged. This would allow dirt to be wiped off the main body during sweeping.
- the dustpan could have an upper edge on which flocked material is arranged.

A cleaning device (4, 4 a, 4 b, 4′ b, 4 c, 4′ c, 4 d, 4′ d) for cleaning surfaces, comprising a main body (5, 5 a, 5 b, 5 c, 5 d) made of foam, is characterized, in regard to the task of designing and improving a cleaning device of the type mentioned above such that it has an abrasive surface with which liquid, but at the same time hair and dirt particles, can be reliably collected, in that flock material (2, 2 d) is assigned to the main body (5, 5 a, 5 b, 5 c, 5 d) and the flock material (2, 2 d) is arranged on a surface (6, 6 a, 6 b, 6 c, 6 d) of the main body (5, 5 a, 5 b, 5 c, 5 d) which can face a floor surface to be cleaned.
Description
- This application is a U.S. National Phase Application based on International PCT/EP2012/004876 filed Nov. 26, 2012 and also claims priority to German Patent Application Serial No. DE 10 2012 004 331.7 filed Mar. 7, 2012, the entire disclosures of which are hereby incorporated herein by reference.
- The invention relates to a cleaning device according to the preamble of
claim 1. - Cleaning devices for floor cleaning which comprise a main body made of foam are known from the prior art.
- The main body is advantageously capable of soaking up liquid and delivering it to a floor surface to be cleaned. A main body of this type can also be easily wrung out and thereby emptied of water. A main body made of foam which is not filled with liquid can absorb a liquid film from a floor surface by virtue of capillary action.
- In practical applications, it is frequently necessary to remove stubborn dirt from a floor surface. It is also frequently necessary to gather and remove breadcrumbs, hair or grains of sand from a floor surface.
- The cleaning devices known from the prior art often fail to meet the aforementioned requirements.
- In light of the above, a cleaning device is known from US 2004/0187241 A1 which is relatively cumbersome to manipulate, since bristles are arranged separately on a handle.
- When these bristles become damaged or worn, essential parts of the cleaning device must be replaced. Moreover, because the bristles are relatively inflexible in design, they are difficult to clean.
- The object of the invention is therefore to design and develop a cleaning device of the type described in the introductory section such that it has an abrasive surface that can also be used to reliably collect both liquid and hair and dirt particles.
- This object is achieved by the present invention with the features of
claim 1. - A cleaning device according to the invention for cleaning surfaces, particularly for floor cleaning, comprises a main body made of foam.
- According to the invention, flocked material is allocated to the main body, with the flocked material being arranged on a surface of the main body that can be turned to face a floor surface to be cleaned.
- The invention utilizes the knowledge that flocked material has relatively hard and resilient fibers which can have an abrasive effect. The flocked material can be used to remove stubborn dirt from a floor surface. Furthermore, a suitable arrangement of the flocked material can ensure that hair, crumbs and/or dirt particles will be collected by the flocked material. The invention utilizes the knowledge that the flocked material can give a relatively soft main body made of foam an abrasive character. Specifically, it is acknowledged that the advantages of the foam, namely the water storage capacity thereof, can be combined with the advantages of a hard surface, namely the flocked material.
- Since the flocking is applied to a standard wiping surface, the user can apply the flocked regions easily and without assuming anatomically uncomfortable contact angles in order to remove dirt.
- The lifespan of the flocking is adapted to the lifespan of the foam, so that when the foam is replaced, the original, good-as-new cleaning capacity can again be achieved. The flocking is applied to the flexible foam. As a result, when the cleaning device is rinsed with water the fibers of the flocked material are more thoroughly cleaned, since they are able to move relative to one another.
- Unexpectedly, a tremendous increase in cleaning ability, specifically more than 200%, in terms of the removal of stubborn dirt and the collection of hair, particularly dirt, over that of conventional foam is realized. This is combined with easy rinsability of the foam and the flocked material.
- A cleaning device which attains the above-stated object is thereby provided.
- The flocked material could be arranged in an insular manner and/or isolated in regions on the surface in such a way that the surface is not completely covered by flocked material. The insular arrangement ensures that channels and/or interstices are created between individual islands of flocked material. Hairs and particles of dirt can be easily collected and removed within these channels or interstices. The isolated arrangement of flocked material in regions on the surface ensures that a sufficient amount of the surface is not covered by flocked material. The part of the surface not covered by flocked material is available for absorbing liquid from a floor surface and/or for delivering liquid to the floor surface.
- In light of the above, the flocked material could comprise fibers and an adhesive matrix, wherein the fibers are injected into the adhesive matrix such that unattached ends of the fibers project outward from the adhesive matrix. The fibers injected into the adhesive matrix are very securely connected to the adhesive matrix. Moreover, the fibers are arranged tightly adjacent to one another, so that they form a relatively hard cluster that has an abrasive effect. The unattached ends of the fibers are capable of removing stubborn dirt from a floor surface. The unattached ends of the fibers can be moved like a brush over a floor surface.
- The flocked material could comprise fibers having a thickness ranging from 20 to 100 decitex (dtex). Unexpectedly, it has been found that fibers of this thickness are stiff enough to have an abrasive effect, while being fine enough for small particles of dirt to collect among them, in the manner of a comb.
- The flocked material could comprise fibers having an extension length of 1 to 3 mm. The extension length is understood as the region of a fiber that is not encompassed within the adhesive matrix. An extension length of 1 to 3 mm ensures that the fibers are sufficiently flexible, but are also sufficiently hard and rough.
- The flocked material could be arranged directly on the main body made of foam. In this specific embodiment, the adhesive matrix is arranged directly on the main body. As a result, the surface of the foam is covered only by the adhesive matrices. All other regions of the surface of the foam are available for absorbing and/or delivering liquid.
- The flocked material could be arranged on a layer which is attached to the main body made of foam. It is therefore specifically possible for fleece or non-woven fabric to be laminated to the main body. In this specific embodiment, the flocked material can be easily applied in a specific pattern to the layer, in a separate production step. With the arrangement of complex patterns, in particular, it is expedient to first form said patterns on a flat surface made of fleece or non-woven fabric, and to deform the fleece or non-woven fabric once the pattern has been formed, during attachment to the main body. Complex patterns of flocked material can thereby be easily arranged on a main body having curved surfaces.
- A gripping or holding means could be arranged on the main body. The gripping or holding means allows the cleaning device to be easily gripped manually.
- The gripping or holding means could be designed as a head with a receptacle for a handle, or could have such a head. This specific embodiment allows a handle to be easily screwed or snapped into the receptacle. The cleaning device can thereby be easily used for floor cleaning. In particular, the cleaning device can be used as a mop.
- The gripping or holding means could be designed as retaining strips, which can be enmeshed with another device. The retaining strips can be inserted into a device in the manner of a rail. The device itself can be equipped with a handle, which allows the finished cleaning device to be easily guided over a floor surface.
- The flocked material could be designed as an elongated edge which extends along a scrubbing edge of the main body which can be turned to face the floor surface to be cleaned. The elongated edge forms an isolated region of flocked material on the surface of the main body. This specific embodiment allows stubborn dirt to be removed using the scrubbing edge of the main body, while a liquid film can be absorbed from the floor surface using an edge that faces away from the scrubbing edge.
- In light of the above, a set could comprise a cleaning device of the type described herein and a dustpan, wherein the dustpan is equipped with flocked material. In this specific embodiment, a main body made of foam can be wiped off on the inner side walls of the dustpan. This allows the flocked material to remove hairs and/or dirt particles from the main body and collect them. As described above, flocked material is produced by injecting fibers into an adhesive matrix. More specifically, the fibers are injected electrostatically into an adhesive, wherein the fibers are preferably 22 dtex, 50 dtex or 100 dtex fibers.
- In light of the above, the dustpan could have a supporting edge on which flocked material is arranged. This would allow dirt to be wiped off the main body during sweeping.
- The dustpan could have an upper edge on which flocked material is arranged. The upper edge would have a particularly large wiping surface.
