Description

Technical area

The invention relates to a mop head and a mop comprising the mop head.

The mop head comprises a support body and textile fringes which extend in the longitudinal direction, wherein the fringes are respectively fixed in the longitudinal direction on the one hand on the support body and in the longitudinal direction on the other hand have an opposite end.

State of the art

Such a mop head and a mop comprising such a mop head are well known.

The textile fringes are in each case formed coincidentally and comprise threads of identical design, which extend in the longitudinal direction parallel to each other and are associated with each other loosely.

During the intended use of the mop head, when the fringes are exposed to water and / or heat, they have a matching shrinkage behavior in the longitudinal direction.

From the US 4,995,133 a mop head is known, comprising a support body of textile fringes extending in the longitudinal direction, the fringes are each fixed in the longitudinal direction on the one hand on the support body and in the longitudinal direction on the other hand have an opposite end, wherein at least one fringe at least two strands with a first strand and a second strand and wherein the strands are in direct contact with each other.

In the strands threads are summarized.

The fringes of the previously known mop head are strongly three-dimensionally deformed and have a deviating from the plan shape. Such a shape may for example be formed by a spindle-shaped shape of the fringes or simply in that the fringes have wrinkles, creases, wrinkles, grooves, bends, rollers, openings, depressions or the like.

Due to the strong three-dimensional shape of the fringes is to be achieved that they are better suited to absorb impurities and / or liquids.

The fringes can be made of a variety of suitable materials, the material, the previously described shape of the fringe provided, is of secondary importance.

The strands and strands of the strands used in the fringes of the prior art mop head are each of the same type, and the object underlying the prior art mop head is seen in the fact that the fringes used are used throughout the service life keep their strong three-dimensional shape.

This can happen, for example, because the fringes have a three-dimensional core.

In 9C is a fringe with two strands revealed, which entwine each other.

In 9A discloses a fringe without strands, in which the threads of the fringe are held with a fixing thread in its spindle-shaped arrangement, to prevent the spindle-shaped fringe from moving back against its direction of rotation. The fixing thread extends in a spindle shape from the mop head to the free end of the fringe.

Instead of the fixing thread, for example, an adhesive for fixing the shape of the twisted fringe can be used.

From the WO 02/076277 A1 a wet mop cover is known, which has a fabric with at least one cleaning active side and two rear side to the cleaning active side holder pockets, wherein the at least one cleaning-active side consists of a knitted fabric made of plastic microfibers on which at least one suction pad made of plastic material is arranged , The knitted fabric consists of textile fibers, for example of polyester fibers or polyester threads. The at least one absorbent pad is sewn to the knitted fabric and arranged in a pocket or bag-shaped cavity. The cavity may have two chambers. The absorbent pad consists for example of one plate per chamber.

The previously known wet mop cover is based on a cleaning textile, which consists predominantly of cotton and synthetic fibers, with both types of textiles being mixed and having opposing properties. As an example, cotton is called, which has a water suction of about 250%, in contrast to plastic fibers, which have virtually no water suction. Next is described that the abrasiveness of cotton is very low, the plastic fibers on the other hand, high.

It has been recognized that the textile types with different properties that are sewn together have a different shrinkage behavior during the intended use of the wet mop cover. This can damage the wet mop cover and lead to premature failure.

Particularly problematic are flat mop covers whose drying shrinkage is 30% compared to the wet state. As a result of different shrinkage behavior, extreme distortions of the different materials relative to one another and, as a result, damage to the flat mop cover occur.

In order to avoid the disadvantages mentioned above, it was further recognized that the materials used should, if possible, not have any divergent shrinkage behavior.

An as uniform as possible wet mop cover, which is made entirely of plastic, even a total of polyester, is disclosed as advantageous. The Flächengewirke and the cavity containing the absorbent pad then have no significant differences in the shrinkage behavior.

Presentation of the invention

The invention is based on the object, a mop head and a mop of the type mentioned in such a way that the fringes are better adapted to the particular circumstances of the application and have consistently good performance characteristics during a long service life. Also, the appearance of the mop head in the manufacturing condition and during normal use under water and / or heat should not differ significantly from each other.

This object is achieved by the features of claims 1 and 10. In advantageous embodiments, the dependent claims relate.

To achieve the object, a mop head is provided, comprising a support body and textile fringes extending in the longitudinal direction, the fringes are respectively fixed in the longitudinal direction on the one hand on the support body and in the longitudinal direction on the other hand have an opposite end, wherein at least one fringe at least two strands with a strand and a second strand, wherein the strands touch each other directly adjacent, each strand manufacturing reasons, the same length, the strands have during the intended use of the mop head in water and / or heat due to the material a different shrinkage behavior in the longitudinal direction and wherein the strands are fixed to each other by at least one fixation in the longitudinal direction such that the strands are kept in the same length during the intended use of the mop head.

In addition, a mop is provided to solve the problem, comprising the mop head described above, wherein the mop head is connected to a stem.

It is advantageous that the strands, which are used in a fringe for use, are well adapted to the particular circumstances of the application. Thus, for example, it is possible to design one of the strands in such a way that it can absorb or dispense comparatively much cleaning fluid, so that this strand thus has substantially sponge-like use properties. In the same fringe, at least one other strand can be used which has deviating usage properties. The differing performance characteristics may consist in that the second strand has more abrasive performance properties and consists of a textile material that practically neither absorbs nor releases cleaning fluid. One and the same fringe is therefore multifunctional and, for example, well suited to first moisten the surface to be cleaned, then to remove impurities abrasive from the surface to be cleaned and then, after the mop head has been washed and wrung out, to resume moisture from the previously cleaned surface ,

Different textile materials in a fringe often have a material-dependent shrinkage behavior in the longitudinal direction when exposed to water and / or heat. For example, it may happen during intended use that the second strand, based on the first strand, shrinks more in the longitudinal direction when exposed to water and / or heat. This would affect the quality of the cleaning result.

In addition, it would be disadvantageous that the mop head by different degrees of shrinkage the strands would look aesthetically unappealing.

To exclude the aforementioned disadvantages, it is therefore provided according to the invention to compensate for this different degrees of shrinkage of the strands, that the strands of the fringe are fixed by fixing in the longitudinal direction to each other so that the strands during the intended use of the mop head in the same length are held. Even under the influence of water and / or heat, the strands of the fringe thus always have the same length. From the support body to the opposite end, the fringe over its entire length therefore has consistent performance characteristics. So also in the region of the opposite end of the fringe, both strands are effective, and the mop head has even during its intended use on an appearance that is virtually indistinguishable from the production-related appearance.

The fixation can be designed as a holding thread system. The retaining thread system may comprise at least one retaining thread, which is formed for example as a retaining mesh.

The fixation changes its length, regardless of water and / or heat also not.

The fixation causes the strand, which has a greater shrinkage during the intended use of the mop head with water and / or heat, correspondingly upsets the adjacent strand with the relatively lower shrinkage. Due to the compression of the strand with the relatively lower shrinkage, this then usually has a voluminous shape, which contributes to a further improved cleaning result.

Length differences of the adjacent strands of normally up to 40% can be easily compensated by the fixation.

All textile fringes of a mop head can be designed as described above.

According to another embodiment, it may be advantageous that only the textile fringes arranged on the surface of the mop head are designed as described above. Within a bell-shaped mop head textile fringes can be provided, which are designed differently. As a result, the mop head can be adapted even better to the particular circumstances of the application, depending on how the mop equipped with the mop head is guided by the user over the surface to be cleaned.

The fringes on the peripheral outer surface of the mop head have different usage characteristics than the inner fringes.

According to an advantageous embodiment, it may be provided that the fixation of the fringe is formed by at least one holding thread system which extends substantially transversely to the longitudinal direction.

The retaining thread system may comprise at least one retaining thread, which is formed for example as a retaining mesh.

The extension of the holding thread system transversely to the longitudinal direction results in a longitudinally effective toothing effect of the strands arranged adjacent to one another. A relative displacement of the adjacent strands, which would lead to strands of different lengths, is thereby excluded. In the region of the holding thread system, the fringe is constricted, whereby, viewed in the longitudinal direction, on both sides of the constriction results in a relatively voluminous shape of the fringe. During the intended use of the mop head, the strand with the relatively lower shrinkage is even more bulky due to its compression and the cleaning result is improved.

The holding thread system can be formed by a retaining stitch of thread. The retaining flap is designed so that it ensures reliable fixation of the mutually fixed strands even when the mop head is used for a long period of use.

The retaining thread system may circumferentially surround the fringe at least at one point of its extent. However, in order to reduce the mechanical stress on the holding thread system, it is expedient to provide a plurality of points in the longitudinal direction of the fringe, which are peripherally enclosed by the holding thread system. The mechanical stress of the holding thread system arises from the fact that the strand with relatively greater shrinkage upsets the strand with relatively less shrinkage and the retaining thread system nevertheless has to fix the strand with relatively less shrinkage on the strand with relatively greater shrinkage in the region of the retaining thread system. A relative movement between the strands in the region of the holding thread system is excluded.

Differently large shrinkage of the strands can be compensated particularly well by the fact that the holding thread system the fringe in Longitudinally encloses the support body to the opposite end circumferentially. For example, there is the possibility that the holding thread system, the fringe, viewed in the longitudinal direction, uniformly and circumferentially encloses, more preferably substantially helical.

According to an advantageous embodiment, it can be provided that the holding thread system holding threads, for example, holding tabs, which, viewed in the longitudinal direction of the fringe, each having a width relative to each other, which corresponds approximately to the thickness of the fringe. As a result, the different strands are fixed on the one hand reliably in the longitudinal direction to each other, and on the other hand, such a fringe has sufficient cleaning surface to quickly and thoroughly clean a surface to be cleaned can.

For household applications, it has proven to be advantageous if the holding thread system has a regular distance. Between the support body and the opposite end, the strands, for example, are fixed about every one centimeter in the longitudinal direction, so as to reliably fix the strands together, to compensate for the different shrinkage of the strands and to maintain the aesthetically pleasing appearance of the mop head under all operating conditions ,

The strands can be arranged parallel to one another in the longitudinal direction. The fringe then has a substantially rectangular cross-section and well-defined areas with different performance characteristics. Deviating from the strands can surround each other spirally.

The fringe then has a substantially round cross-section, wherein the regions with different performance properties, viewed in the wiping direction, are designed to merge into one another.

According to a particularly advantageous embodiment, it may be provided that the strands are arranged parallel to each other in the longitudinal direction, that the fringe has at least three strands, wherein two strands are formed coincident, comprise matching first threads and during normal use have the same shrinkage and a strand Deviating from this, comprises second threads and during normal use has a greater or lesser shrinkage in the longitudinal direction and that the strand comprising the second threads disposed between the strands with the matching first threads and fixed by the fixing in the longitudinal direction between them is.

It is advantageous that the mutual support effect of the strands with different shrinkage is particularly good. The symmetry also results in an attractive appearance of the mop head / mop. Also, three strands can be used, each with different materials.

During normal use, the second threads can absorb or release less cleaning liquid and / or have abrasive performance properties than the first threads. The mop head is thus well suited for cleaning heavily soiled surfaces.

The mop head described above may be connected to a handle and thereby forms a mop having the advantageous properties described above.

• 2 a fringe, as in the mop head accordingly 1 used.

Embodiment of the invention

In 1 a bell-shaped mop head is shown, which together with the stem 13 forms a mop.

The mop head comprises a support body 1 made of a polymer material. The textile fringes 2 , each on the support body 1 are fixed, extend bell-shaped in the longitudinal direction 3 to the opposite end 4 , The opposite end 4 is formed in the embodiment shown here as a free end, but may also be loop-shaped.

The fray 2 form the circumferentially outer surface of the mop head; inside the mop head, so under the fringe 2 , Further fringes are arranged, the deviating, for example, the same material, are formed.

The fray 2 in the embodiment shown comprise three strands 5a . 5b , 6, where two of the strands 5a . 5b are formed consistently. The strands 5a . 5b therefore have matching first threads 7 which are well suited to pick up or dispense cleaning fluid.

Deviating from this is the second strand 6 formed, the second threads 8th includes, wherein the second threads 8th , compared to the first threads 7 , absorb or release less cleaning fluid and have more abrasive handling properties.

Due to the different materials that make up the first threads 7 and the second threads 8th exist, they have a different material shrinkage on water and / or heat due to the material. The shrinkage of the second threads 8th is greater under the circumstances described above, than the shrinkage of the first threads 7 , This indicates the second strand 6 during normal use when exposed to water and / or heat due to the material due to a greater shrinkage than the strands 5a . 5b on.

The fixation 10 is formed by a holding thread system and fixes the strands 5a, 5b, 6 in the longitudinal direction 3 together. By this Verkrallungseffekt each adjacent strands 5a . 6 ; 6 . 5b is achieved that the strands 5a . 5b . 6 even during the intended use of the mop head always an equal length 9 show, thereby the fringes 2 from the support body 1 up to her in the longitudinal direction 3 opposite end 4 consistently clean well and have an appearance that is always the same.

The fixation 10 is through the retaining pocket 11 formed, wherein the retaining pocket 11 is a substantially equal distance from the support body 1 to the opposite end 4 the fringes 2 having. The retaining flap 11 extends substantially transverse to the longitudinal direction 3 the fringes 2 , so that thereby a mechanical cleavage of the strands 5a . 5b . 6 longitudinal 3 results in each other and these are always fixed in the position shown here relative to each other.

The bodies 12 on which the fringes 2 through the retaining pocket 11 are constricted, extend, in the longitudinal direction 3 considered substantially uniformly from the support body 1 to the opposite end 4 ,

In general, there is the possibility that at least one fringe of the mop head, for example, only two strands or more than three strands.

If a dual composite is used, the two strands can be arranged so that they surround each other in a spiral shape.

For domestic applications, it has proven to be advantageous if the retaining mesh 11 has a mesh size of about 1 cm. Between the support body 1 and the opposite end 4 are the strands 5a , 5b, 6, in the longitudinal direction 13 considered, so about every centimeter fixed together, so the different shrinkage of the strands 5a . 5b . 6 balance and maintain the aesthetically pleasing appearance of the mop head.
