Description

Hand-operated cleaning device and mop cover

Field of the invention

The invention relates to a hand-operated cleaning device with a handle with a handle and a cleaning head and a mop cover, comprising a textile element that can be releasably connected to a handle.

State of the art

There are many hand-operated in the prior art

Cleaning equipment known. These include one of the

Operator to gripping handle and have one with the handle usually articulated connected

Cleaning head on, itself as a cleaning device

is designed, e.g. a sweeping device or a

Represents Abstreiteinrichtung, or at the one

Cleaning device, such as a mop cover, attachable.

In particular, mops consist in the prior art of three basic elements. These are on the one hand the handle handle, on the other hand a mop holder, which is pivotally connected to the handle handle, and as a third element, a mop cover that can be connected to the mop holder. To connect a mop cover with a mop holder, various concepts are known. The mop cover can be attached via a Velcro connection or another releasable connection to a rigid, plate-shaped mop holder. Alternatively, solutions are known in the art, according to which the mop holder can be inserted into receiving pockets of a mop cover. For this purpose, the plate-shaped

Mop holder provided with folding wings, for cleaning or changing the mop cover from an extended position with mutually latched folding wings in a second

Position can be brought, in which the folding wings closed on each other. In this position, the mop cover can be either washed out hanging on the mop holder or expressed in a press or removed completely from the mop holder. The mop holders, which are generally configured in an elongated form, can be folded around one another in the longitudinal direction about a pivot axis, as is known from EP 0 757 903 B1, or else pivoted about an axis perpendicular to the longitudinal extension of the mop holder, as for example in the EP 0 663 178 Bl is described.

Such as mop designed cleaning equipment

Although allow a simple and convenient replacement of the mop cover, but is the mop holder itself over a

Universal joint firmly connected to the mop holder. For the

Performing other cleaning tasks, a separate, hand-operated cleaning device with its own handle and its own cleaning head, e.g. in the form of a broom, from

Cleaning staff are carried separately.

The operation of the above described mop in the prior art is simple, but it is always

Find that untrained cleaning staff even with mop holders with only a single foot-operated

Locking button still has problems. Therefore, that exists

Need for a hand-operated cleaning device, which is modular and independent of the

used cleaning head is always to operate the same and the simplest possible way.

Presentation of the invention

The invention has for its object to propose a hand-operated cleaning device that can be fastened in the simplest and most convenient way with a cleaning head. The invention further relates to a mop cover, which constitutes such a cleaning head. This object is achieved by a hand-operated cleaning device with the features of claim 1 and a mop cover with the features of claim 13. preferred

Embodiments follow from the remaining claims.

The hand-operated cleaning device according to the invention comprises a handle with a handle and a handle

Fastening device comprising two fasteners, and a cleaning head, the two

Includes attachment elements which are arranged and designed so that they can be coupled to the fastening elements of the handle. At least one fastening element and the associated attachment element comprise permanent magnets, which are preferably embedded in plastic. In other words, the connection between the handle and the cleaning head is effected at least two attachment points. Each attachment point consists of a fastener on the handle and an associated attachment member on the cleaning head. At least one such fastening pair consisting of fastening element and attachment element has permanent magnets. In order to reduce or completely avoid corrosion phenomena on the magnet in the cleaning insert, the permanent magnets are preferably completely embedded in plastic.

The advantage of the solution according to the invention is that on the one hand different cleaning heads can be connected to the handle in a simple manner. Since at least one pair of permanent magnets is provided, the connection between the handle and cleaning head can be designed so that two attachment points between the handle and

Cleaning head are provided and one or both

Attachment points via a pair of permanent magnets is effected. In this way, the cleaning head mounted in a very simple manner on the handle, again removed from this and by another cleaning head be replaced. Another advantage of using

Permanent magnets is that they can define a preset release force depending on the arrangement and strength. A pre-set release force ensures that the cleaning head does not undesirably come off the handle during use. At the same time, however, by the use of a compound by means of permanent magnets

to ensure that a certain tensile force is not exceeded. In other words, can the

Connection between handle and cleaning head so

adjust that the cleaning head when properly

Use remains coupled to the handle, but can be easily solved by the handle, as soon as an increased force occurs. Such a situation occurs not only when the operator specifically pulls on the handle and z. B. fixed with a foot cleaning head while doing so, but may also occur in situations when, for example, with a dry or wet wiping this gets stuck on a table leg. If, in such a case, the handle then releases from the mop head, can

damage may be avoided otherwise the cleaner may jerk up on the table leg and cause objects standing on the table to fall.

Furthermore, the connection by means of permanent magnets but also to make the connection easy. Since strong permanent magnets only have to be brought into relative proximity to each other to center each other and connect to each other, the connection between the handle and cleaning head can be significantly simplified. The additional attachment point can also be configured via a pair of permanent magnets. In this case, it is particularly easy for cleaning personnel to couple the handle with the cleaning head. However, it is equally conceivable that only one attachment point is formed by permanent magnets and on the other side is a simple positive connection. Also In this case, the attachment is simple, because the two fasteners and attachment elements can be configured so that for coupling the cleaning head to the handle first the first fastener of the handle is associated with the associated attachment member of the cleaning head, for example, by one of the two elements engages positively in the other.

Subsequently, the handle only has to be pivoted until the permanent magnets have been brought close enough to each other that they automatically couple with each other. It must therefore by the cleaning staff, the handle only at one point according to the cleaning head exactly

can be arranged, while the second connection point does not need to be placed so precisely, since the permanent magnets take over the required mutual centering automatically.

According to a preferred embodiment of the invention, the cleaning head is a sweeping device, stripping device or a window cleaning device. These different

Cleaning heads are in the professional use of

Cleaning staff often needed, so currently usually separate cleaning equipment for the various

Tasks are carried. The solution according to the invention allows the coupling of different cleaning heads to one and the same due to the modular structure

Handle.

According to a preferred embodiment of the invention, the cleaning head is a mop. This embodiment is

especially of interest when the mop is designed hold-free, i. the handle directly on one

Mop cover can be attached. Unlike the dry and wet wiping devices known from the prior art, the cleaning device according to the invention thus only consists of two separately provided elements, namely the handle and the cleaning head, which is already the mop. It is thus the handle can be attached directly to the mop cover. A mop holder hingedly connected to the handle, as used in the prior art, can be dispensed with in this case.

Preferably, at least one fastening element comprises a form-locking element which forms a positive connection with a complementary shaped form-fit geometry of the associated attachment element. Here are several options conceivable. When providing two

Fasteners can both fasteners

Permanent magnets include, in addition to a

Fixing point or both a positive connection element

is provided. Furthermore, at one of both

Attachment points be provided a magnetic connection and on the other attachment point a positive connection element. It is also possible at both attachment points

To provide positive locking elements, wherein an attachment point is formed over correspondingly shaped or coated with appropriate shaping permanent magnets. Finally, it is also conceivable that a magnetic connection is provided with additional positive locking element only on one of two attachment points, while the second attachment point is formed of a fastener and associated attachment member which in the coupled state two

have abutting surface with high frictional resistance.

In the case of the provision of a positive locking element, this is preferably designed such that the positive locking geometry of the at least one fastening element of the handle comprises a protruding element, which is preferably spring-loaded in the protruding position. This represents a concrete possibility of how a form fit geometry can be realized. The spring load of the

protruding element facilitates the engagement of the protruding element in a corresponding recess of the associated attachment member. It is preferred that this form-fitting geometry is developed such that the positive-locking element of the at least one attachment element is a recess which receives the protruding element, and wherein the recess comprises a first region which is shaped corresponding to the geometry of the protruding element, and a second region, which ramped chamfer includes. In this way, a spring-loaded

Design locking lug, which can be solved without a release mechanism on the handle. To lock the spring-loaded protruding element engages under relief of the spring in the recess in the associated attachment element. To release, the handle can be brought into a certain position relative to the cleaning head, e.g. exactly in a vertical position relative to the lying on a flat surface cleaning head. In this position, there is a ramped chamfer between the

Recess for the spring-loaded, protruding element and the front surface of the attachment member on

Cleaning head. If the handle defined in this

Position is brought under a predetermined tensile force from the cleaning head Vierden, while in other angular positions between the handle and cleaning head, the positive connection between the handling-side fasteners and the cleaning head side

Mounting elements this is not allowed.

According to a preferred embodiment of the invention, the fastening device of the handle comprises two pivoting levers which are pivotally connected to each other via an axle, each pivoting lever carrying a fastening element, and the fastening elements by an elastic element, preferably a torsion spring, on both pivoting levers in Area of the axis is arranged, towards the

Attachment elements are biased. This embodiment of the handle is particularly preferred in connection with the

Use of at least one attachment point, ie one Fastening element of the handle and the associated

Attachment of the cleaning head as

Form-fitting pair. Through the use of pivot levers, the two, each attached to a pivot lever fasteners can be biased outward. In other words, the two fastening elements of the handle are moved away from each other by the spring-loaded pivot lever and thereby move substantially in a direction perpendicular to the longitudinal extension of the handle

away from each other. When the associated attachment elements are arranged on the cleaning head so that their with the

Fasteners of the handle coming into contact

Contact areas facing each other, then the fasteners of the handle by the elastic

Pressed element towards the contact elements and thus provide a secure connection between each

Fastener and the associated attachment element ago.

Preferably, the hand-operated cleaning device further comprises an actuating device in the region of

Handle whose operation changes the position of at least one fastening element and / or the positive-locking element. For actuating the at least one grip-side fastening element and / or positive-locking element of

Handle are any known in the art

Variants conceivable. So it is possible the

However, to provide fasteners on pivot levers, each pivot lever with a tension element, such.

Cable is provided, the actuation of at least one of the fasteners by a suitable

Actuator allowed in the handle. Another alternative is the provision of a sliding sleeve in the region of the handle, which can be moved in the axial direction of the handle and acts in the shifted state on one or both spring-loaded pivot lever as a carrier of a fastener. By moving the Displacement sleeve in the axial direction thus a fastener or both can be changed in position, preferably in a direction perpendicular to

Longitudinal extension of the handle and preferably on the

Longitudinal axis of the handle too. In addition to the change of

Position of at least one actuating element, it is equally possible to change a positive locking element as part of the actuating element with respect to its position. A change in position may involve an axial displacement of a protruding one

Form-fitting element include, but also a rotation of a form-fitting element, so that this in a

correspondingly shaped recess in the associated

Attachment element can engage and moves back after loosening the actuator in the region of the handle back to the original position, where a lock between the fastener and the attachment member. In the embodiment of such

Positive locking connection and in particular the locking described above should be taken to ensure that the described advantage of an adjustable release force between the handle and cleaning head is not prevented.

According to a further preferred embodiment, the attachment elements of the cleaning head each have a first contact surface and the first facing each other

Contact surfaces of the two attachment elements are arranged at an angle to each other. The fastening elements of the handle have associated second contact surfaces whose angular arrangement is complementary to the first contact surfaces.

An angular arrangement is understood here to mean that the contact surfaces are at an angle to any plane in which the longitudinal axis of the handle is located. In this way it can be achieved that the required force for releasing the handle from the cleaning head are configured by the angled design of the surfaces to each other and the corresponding orientation of the angled surfaces to each other can. So the first contact surfaces can be so angled

be arranged to each other, that they are in one

Working position ,, in which the longitudinal axis of the handle is approximately at an angle of 45 ° to 60 ° relative to the arranged on a flat surface cleaning head, the

Pull-out force is high, while in a position in which the longitudinal axis of the handle is perpendicular to the standing on a flat surface cleaning head, the handle with little effort from the cleaning head can be solved.

According to a further preferred embodiment of the invention, the fastening elements are rotatably mounted on the handle on the fastening device. In the provision of

Fastening elements in the form of a plastic

overmolded permanent magnet can be poured in a very simple manner an additional axis of rotation with the sheath of the permanent magnet, so that a

Permanent magnet with a substantially cylindrical basic geometry can be easily rotatably mounted on the handle. The general provision rotatably mounted on the fastening means fasteners serves to improve the handling of the hand-operated cleaning device by not pivoting the handle relative to the cleaning head, the position between the

Fastening elements and attachment elements is changed, but maintain a rigid connection with each other and the fasteners are pivotable relative to the handle. This requires that the axes of rotation of the fastening elements are aligned with each other and are arranged substantially perpendicular to the longitudinal axis of the handle.

Preferably, the actuating device comprises an in

Slidable longitudinal member of the handle handle, preferably a sliding sleeve whose displacement changes the position of at least one fastener. This embodiment can be used in particular with outwardly spring-loaded legs. By the Providing a sleeve that can be moved downwards, these swiveling outward swivel lever against the

Spring force of a torsion spring are pressed inward, so that in this way a rigid pin connection in addition. to solve at least one magnetic connection.

Preferably, both fasteners and both associated Änbringungselemente permanent magnets and the tensile force in the longitudinal direction of the handle to release the

The connection between the handle and the cleaning head is more than 10 N. The specification of a minimum tensile force of 10 N ensures that there are no delays due to unintentional, automatic release of the cleaning head from the handle.

The mop cover according to the invention comprises a textile element, to which attachment elements are attached, wherein at least one of the attachment elements comprises a protected against contact with liquid permanent magnet. The flat mop cover is also dimensionally stable and can be coupled directly with a rod-like handle. Finally, the attachment elements of the mop cover are arranged and

designed to make a releasable connection with fasteners of the handle. The essential

The point of view of the mop cover according to the invention is that it can be coupled directly with a rod-like handle. It is thus interposed between the flat mop cover and a handle no separate mop holder.

At the same time, the flat mop cover is dimensionally stable. The term "dimensionally stable" does not mean that the mop cover is completely rigid, but is intended to express that the textile element has a certain dimensional stability. This means that the flat mop cover, for example, when the entire cleaning device is raised using the mop cover according to the invention by a flat surface, essentially retains its shape. The advantage of dimensional stability is that a hand-operated cleaning device using the mop cover according to the invention can be used for example for wiping stairs. In doing so, the cleaning device must be raised from step to step, and placed on the next higher or next lower step. Only a sufficiently dimensionally stable trained

Mop cover can be used here meaningful, because it rests flat again after placing it on the next tread. Also for cleaning the risers, it is important that the mop cover sufficient

Form stability has, otherwise this no pressure

can pass, which is exercised by the handle on the mop cover.

According to a preferred embodiment, the

Attachment elements together via a rigid

Intermediate element connected. This measure serves to keep the mounting elements of the mop cover at a predetermined distance from each other. This is necessary because in the cleaning of mop covers at high washing temperatures, a certain shrinkage of the textile material is not

can be excluded. However, since it essentially depends on the exact positioning of the attachment elements present directly on the mop cover relative to the fastening elements of the handle, by connecting the two

Attachment elements are ensured by, for example, a rigid strap the correct distance between the attachment elements.

According to another alternative embodiment of the

Invention, the textile element is pocket-shaped and provided with a substantially central opening on one of the sides of the textile element for coupling the handle, wherein the attachment elements are in the region of the central opening. The provision of a textile

Elements, which is pocket-shaped, makes it possible to different wiping surfaces with different To provide characteristics on the two main surfaces of the pocket-shaped textile element. So can

For example, on one of the two main surfaces for releasing adhering dirt a relatively rough surface

be provided, while on the other hand an area with particularly high absorption capacity is provided. The term "bag-shaped" also includes a textile element which is closed on all sides except for the central opening.

Preferably, the textile element comprises fibers whose

Diameter is at least 0.5 dtex and their

Tear strength is at least 35 cN / tex. Such fibers are particularly suitable for the mop cover a

to provide sufficient dimensional stability.

Preferably, the attachment elements are sewn to the textile element and / or glued and / or welded. All three of these attachment variants are possible because the permanent magnets are protected against contact with liquid. To achieve this, the permanent magnets are preferably completely surrounded by a plastic material, so that also the sewing of the attachment elements to the textile element is possible. In addition to the above-mentioned individual mounting alternatives but also to

Ensuring a secure attachment of the

Attachment elements on the textile element arbitrary

Combinations between the mentioned attachment alternatives possible.

In the case of the pocket-shaped embodiment of the textile element, the mop cover preferably further comprises a dart in the region of the central opening, which represents a closed seam around the central opening and the two main surfaces of the pocket-shaped textile

Connecting elements together. Such a dart closes the central opening, so that in the case of Use of the mop cover for wet wiping

Cleaning liquid can not flow to any appreciable extent in the pocket of the textile element.

In order to provide the mop cover with sufficient dimensional stability, apart from the use of suitable fibers, the mop cover preferably comprises one or more

Stiffening elements in addition to the

Attachment elements are provided and with the

Sewn or glued textile element and / or in

Inner pockets of the textile element are inserted.

Such stiffening elements can, for example

Be plastic strips that are inserted into inner pockets of the textile element of the mop cover and the arrangement and shaping of a dimensional stability in a certain, predetermined direction can be generated.

The same applies to sewn or glued

Stiffening elements whose properties, shape and dimension can be selected so that the dimensional stability in the two main directions of the inner pockets can be influenced separately.

According to a preferred embodiment of the invention, the mop cover further comprises a flexible insert, the

is integrally formed with the attachment elements and is arranged in the pocket of the textile element. Thus, as an alternative to the embodiment according to which

Attachment elements are sewn to the textile element and / or glued and / or welded, also be provided the embodiment according to which the attachment elements are connected to a flexible insert. The flexible insert is preferably made of silicone or other elastic material. The shape and choice of material of the flexible insert can be selected according to the desired dimensional stability of the mop cover. According to a preferred embodiment, the flexible insert is sewn into the pocket-shaped textile material. In this way, the flexible insert can not accidentally slip out of the pocket-shaped textile element and the mop cover is still a one-piece element that directly with the

rod-like handle is connectable. The flexible insert can not with a mop holder in the prior art

be compared, because the textile element of the mop cover is not provided separately to the flexible insert, but represents a single unit.

It is also possible to design the mop cover in such a way that the flexible insert can be inserted into the bag-shaped textile element via an opening in the latter. For example, if the flexible liner does not extend across the entire width of the pocket, it is possible to position the aperture such that the flexible liner is first inserted into the pocket in one direction through the aperture, but subsequently in a second direction perpendicular thereto the bag to be moved rauss to bring the attached to the flexible insert attachment elements in the region of the central opening.

According to a preferred embodiment of the invention, the textile element has two major surfaces, which as

Wischflächen are configured and different

Have surface characteristics, in particular

different absorption capacity. Next

however, there may be other differences in the surface characteristics of the two major surfaces with different absorbency.

According to a preferred embodiment of the invention, the mop cover further comprises a passive electronic component, preferably an RFID tag. The provision of an RFID tag serves to make the logistics within large to be cleaned To facilitate objects such as hospitals or airports. It is possible to determine when a particular mop cover has been manufactured and commissioned or a specific mop cover can be identified. Also, it can be demonstrated in complaints to which

Times a certain mop cover was cleaned.

RFID tags are suitable passive electronic ones

Components because they are also in the presence of as

Permanent magnets configured attachment elements

work reliably. In addition, RFID tags

inexpensive to produce. If the mop cover is in any case provided with receiving pockets for stiffening elements, then an inner pocket for receiving the RFID tag can be used in the same way, but this is closed by a dart to prevent the loss of the RFID tag.

Preferably, the textile element is substantially

pocket-shaped and has a substantially rectangular shape with two substantially parallel longitudinal edges and two substantially parallel transverse edges, wherein the attachment elements are arranged close to one of the longitudinal edges and the assembly consisting of the two attachment elements is arranged substantially centrally relative to the nearby longitudinal edge , The

Attachment elements preferably have a substantially cylindrical geometry and are so to each other

arranged that the end faces of the two cylinders are facing each other and are arranged at a defined distance from each other.

Ways to carry out the invention

The invention will be described purely by way of example with reference to the embodiments shown in the figures, wherein in all representations in each case the same

Components and assemblies are denoted by the same reference numerals.

Fig. 1 shows a hand-operated cleaning device, the

generally designated by reference numeral 10. The term "manually operated" is intended to express that the cleaning device is not driven by a motor or moved automatically, but is manually moved by an operator. The hand-operated cleaning device 10 has a handle, generally designated by reference numeral 12, which consists essentially of an elongated handle 14 which is in a manner conventional in the art

can be designed. In the present example, the handle handle 14 is provided with a ball handle 16, but this is only to be understood as an example. The handle 12 has a fastening device, not shown in detail in FIG. 1, by means of which the handle 12 can be releasably coupled to a cleaning head 18. In the exemplary embodiment according to FIG. 1, the cleaning head 18 is a mop, of which essentially only one pocket-shaped one is configured

Mop cover 20 is visible.

The hand-operated cleaning device 10 is constructed in modules and can be coupled to various cleaning heads 18, such as a sweeper, stripping or Window cleaning devices that follow the invention described herein only in terms of their mounting geometry and otherwise constructed in a conventional manner and

can be designed. Therefore, as an alternative to that

Wischmop 20 not designed as a broom sweeping device, but also no stripping or

Window cleaning device shown.

The handle handle can be made adjustable in length. The measures required for this are known to the person skilled in the art.

In addition, the handle 12 may be pivotally mounted relative to the cleaning head 18.

Fig. 2 and 3 show a possibility of connection between a lever mechanism 22 on the side of the handle and a unspecified cleaning head 18. On the

Representation of the handle and the handle was

omitted in order to better represent the core elements of the connection between the handle and cleaning head. The lever mechanism 22 is part of a

Fastening device 24, as shown later with reference to FIGS. 9 to 11 as part of the handle. Of the

Lever mechanism 22 is provided with two fasteners 26 which are fixedly attached to the attachment means 24 of the handle. These fasteners 26 cooperate with attachment members 28 which are fixedly attached to the cleaning head 18. In the present example, fasteners 26, as well as attachment members 28, are permanent magnets that are completely embedded in plastic to prevent corrosive attack of cleaning liquor or acidic

To avoid cleaning fluids. The magnetic

Fasteners 26 as well as attachment members 28 are arranged so that the attachment members 28 have contact surfaces facing each other and one

have predetermined distance between them.

Corresponding to this point also the Fasteners 26 contact surfaces for coupling with the mounting elements facing away from each other.

To the fasteners 26 in engagement with the

As shown in Fig. 2, the lever mechanism can be brought into an arrangement in which the individual legs 32a and 32b are pivoted towards each other, so that the total width and thus the distance between the contact surfaces on the

Fasteners 26 reduced. For this purpose, the lever mechanism 22 may be provided with a torsion spring or other elastic element, the two

Leg 32a, 32b in a spread and in Fig. 3rd

biased position shown. However, the position shown in FIG. 3 does not have to correspond to that configuration in which the elastic element is completely relaxed. To improve the connection between the fastening elements 26 and attachment elements 28, it is equally possible, by the elastic element between the legs 32 a and 32 b an additional

Pressing force in the area of the contact surfaces 30 between the fasteners 26 and attachment elements 28 to produce.

In the present embodiment, the

Contact surfaces 30 oriented so that they are parallel to

Longitudinal axis of the handle stem 14 extend. This has the

Advantage that for releasing the connection between the handle and cleaning head an operator only has to pull the handle handle in the longitudinal direction. Thus, the connection between the handle and cleaning head but does not solve automatically in the proper use of the cleaning device, a minimum tensile force in the longitudinal direction of the handle is set to release the connection between the handle and cleaning head of 10 N. This can be due to the strength of the permanent magnets, on the one hand, and the embedding depth of the permanent magnets in the surrounding plastic material, on the other hand also by a given contact pressure in the area of

Contact surface 30 are generated. Further measures are described in the following figures and relate

Positive connection between the fasteners and attachment elements.

The embodiment according to FIGS. 2 and 3 has a permanent magnet connection on both sides

Fasteners and attachment elements.

According to the invention, it is sufficient if at one point a connection with permanent magnets, while the other side, for example, exclusively as

Positive connection is configured.

Fig. 4 shows schematically again a lever mechanism 22, the legs 32a and 32b are pressed apart via an elastic element, not shown, in the direction of arrow A. For this purpose, the legs 32a and 32b are one

common pivot axis 34 movable. With reference to FIG. 4 is to be shown schematically two ways. On the one hand, a sliding sleeve 36 is shown schematically, the above the handle handle 14 and the associated fastening device in the direction of arrow B, i. in the longitudinal direction of the handle handle, can be displaced. By a shift of

Displacement sleeve 36 comes the front end 38 of the

Displacement sleeve 36 in contact with the legs 32a and 32b and presses them against the direction of the arrow A to each other. The sliding sleeve 36 can be actuated via a suitable mechanism on the handle handle of the handle. For example, it is possible that the not shown in Fig. 4

upper end of the sliding sleeve has an inclined surface and by rotation of the sliding sleeve to the

Longitudinal axis the axial movement in the direction of arrow B is caused. In addition to the provision of a sliding sleeve, however, all other kinetics known in the art are also possible in order to move the legs of the lever mechanism toward one another. A second aspect illustrated in FIG. 4 relates to the combination of a connection between the

Fasteners 26 and attachment elements 28 as a magnetic connection and at the same time positive connection. For this purpose, on the one hand both to the

Fastening elements 26 first permanent magnets 40 and in the mounting elements 28 embeds second permanent magnets 42 are provided. In the illustration of Fig. 4, only one attachment member 28 is shown. The second permanent magnet 42 is designed annular. This has the advantage that, in spite of an additionally provided in the attachment member 28 positive locking recess close to the contact surface 46 of the

Attachment element 28 can be arranged, as the

Formschlussvertiefung 44 is located in the center of the annular second permanent magnet 42.

The fasteners 26 are with a

Form-fitting element in the form of a positive locking survey 48 provided whose position and shape corresponding to

Formschlussvertiefung 44 is selected in the mounting member 28, so that in addition to the magnetic coupling and a positive connection between the

Fasteners 26 and the associated

Attachment elements 28 can be produced.

Fig. 5 shows a fastener 26 and a

Änbringungselement 28 in coupled condition. The form-fitting elevation 48 of the fastening element 26 extends into the form-fitting recess 44 of FIG

Attachment element 28. In addition, a first

Permanent magnet 40 and second permanent magnet 42nd

shown schematically. Both permanent magnets are

completely embedded in plastic 49. In addition, Fig. 5 shows an axis of rotation 50 which serves for the rotatable attachment of the fastener 26 to the fastening means 24 of the handle. In the simplest case, the axis of rotation 50 is merely a metal pin whose Fixing in the plastic material 49 can be additionally ensured by one or more annular thickenings 52 and on the side facing away from the attachment member 28 can be rotatably mounted in a suitable manner in the attachment means of the handle.

In Figs. 6a, 6b and 7 are views of a

Attachment element 28 (Fig. 6a, 6b) and an associated fastener 26 (Fig. 7) shown. The

Attachment element 28 has a form-fitting depression 44, which is subdivided into a first region 44a and a second region 44b. In Fig. 6b, the areas are schematically delimited by a broken line against each other. The first region 44a of the form-fitting recess is substantially matched to the geometry and position of a positive locking projection 48, as shown in FIG. 7

is shown. The second area 44b provides a

ramp-shaped recess in the attachment member, which extends only in a certain angular direction relative to the first region, as shown in Fig. 6a can be seen. From Fig. 7 it can be seen that the Forrnschlusserhebung 48 of the fastener 26 may be biased by an elastic member 47, when acting on a force on the positive locking 48 but also against the bias of the spring in the direction of arrow C in the fastener 26 can drive. Now the handle of the

Cleaning head to be solved, the connection between the fastener 26 and the attachment member 28 must be solved. This is possible by the handle is brought into a predetermined angle relative to the cleaning head, for example, is placed perpendicular to this and then a tensile force is exerted on the handle handle of the handle. This has the consequence that the positive locking projection 48 is moved with increasing movement in the direction of arrow C and increasing compression of the elastic member 46, the ramp-shaped slope in the second region 44b until the positive locking survey 48 completely or almost completely in the fastener 26 has been pushed in and the fastener 26 and attachment member 28 can slide along the contact surface 46 past each other to release the connection.

Another alternative design between one

Fastener 26 and a mounting member 28 is shown in Fig. 8. In this case, the contact surface 30 is not parallel to the longitudinal axis of the handle (not shown), but arranged inclined. The provision of an inclined contact surface can, with suitable orientation, serve to increase the release force between the handle and the cleaning head when the angular position between the handle and the cleaning head prevails in the course of a conventional activity, while the connection between the handle and the handle

Cleaning head can be solved very easily as soon as the handle is brought into a certain angular position relative to the cleaning head. This could e.g. be a position perpendicular to lying on a flat surface cleaning head or even inclined beyond the usual working position.

In addition to the provision of an inclined contact surface 30 between the fastening element and the attachment element, it is equally possible for the two to contact one another

To make appropriate contact surfaces with a surface whose coefficients of friction are high, resulting in

In addition, the force required to release the connection increases.

Fig. 9 shows schematically a section through a

hand-operated cleaning device whose grip handle 14

but not fully illustrated. The

Hand-operated cleaning device comes with a

used according to the invention mop cover. This comprises a textile element 52, which is designed substantially in the form of a bag, as best seen in Fig. 11. The Textile element 52 has a substantially rectangular shape with two parallel longitudinal edges 54 and two substantially parallel transverse edges 56. The in the

Embodiment of FIGS. 9 to 11 shown as a substantially rectangular, pocket-shaped mop cover is not a binding feature of the invention and for special cleaning purposes, other geometries can be provided in the same way, especially since it is just a modular system in the system according to the invention in which different cleaning heads light

can be exchanged for each other.

In the sectional view of Fig. 9 of the connection mechanism described above in detail is shown. The

Fastening device 24 of the handle in this case has a lever mechanism 22 with two mutually pivotable legs 32a, 32b. Both fasteners 26 are provided with an axis of rotation 50 and rotatably mounted in this way on the legs 32a, 32b. Both the

Fasteners as well as the attachment elements have permanent magnets. The second permanent magnets 42 of the attachment member are cast in a mounting member 28, which in turn is fixedly connected to the textile member 52. This connection can alternatively or

cumulatively by sewing, welding or gluing done.

So that the fastening device 24 of the handle can easily establish a connection with the mop 20, a central recess 58 is provided on one of the two longitudinal edges 54, which is best seen in the illustration in Fig. 11. To avoid unnecessary intrusion of

Cleaning liquids in the pocket-shaped textile

Preferably, to prevent element 52, the pocket of the textile element is closed about the central recess by means of a dart 60. A mop 20 as described above with fixedly attached to the textile member 52 attachment members 28 does not require a conventional mop holder, but can be attached directly to the handle as a hold-open mop. In order for the mop to have sufficient stability, the fibers used to make the textile element 52 can be configured accordingly. It has proved to be advantageous if the textile element comprises fibers whose diameter is at least 0.5 dtex and if the tensile strength of the fibers is at least 35 cN / tex.

Especially with the exclusive use of

Permanent magnets as a connection mechanism between the fasteners and attachment elements, the exact positioning of the attachment elements is important. At the same time it must be taken into account that textile elements

Washing may be subject to a certain shrinkage. This problem can be solved by, as shown in Fig. 9, a lever mechanism 22 is used on the side of the handle and by the bias of the legs 32 a, 32 b of the lever mechanism minor

Changes in the distance of the attachment elements 28 can be compensated for each other. A second possibility is to use a rigid connection element 62, e.g. to provide in the form of a bracket between the attachment elements.

FIG. 9 includes yet another embodiment of the invention which serves to increase the dimensional stability of the textile member 52. For this purpose, on one of the two inner sides of the main surfaces of the pocket-shaped textile element on the textile element 52 stiffening elements 64 are provided, which may for example consist of elastic plastic. The stiffening elements 64 can be connected in any way with the textile element, for example sewn or glued to this. But it is also possible on the inside, ie the the Inside the pocket facing side of the textile element 52 receiving pockets 66 provide, in which the

Stiffening elements can be inserted. Depending on the desired increase in the dimensional stability of the textile element, all directional arrangements shown in FIG. 9, such as in the longitudinal direction, in the transverse direction or even diagonally, can be provided, as illustrated by the stiffening elements 64a, 64b and 64c. Also the shape of the individual

Stiffening elements is selected in Fig. 9 only by way of example. The same applies to the number of stiffening elements. A receiving pocket may also serve to receive an RFID tag 72 for electronic identification of the mop 20. However, an RFID tag can also be attached to the mop in any other way.

In Fig. 10, an alternative embodiment of the pug 20 is shown. There is no difference to the embodiment shown in FIG. 9 on the side of the handle. The

However, mopseitigen attachment elements 28 are part of a flat insert 68, which may for example consist of silicone material and in the textile element 52nd

formed pocket is located. The design of the

Inlay element 68 with attached attachment elements 28 can have the geometry represented in FIGS. 2 and 3, although in the description of FIGS. 2 and 3 this geometry has been described as a general and unspecified form of a cleaning head. However, it is essential that the provision of an insert 68 does not change the fact that it is a moor-free mop, ie the mop cover in the form of the pocket-shaped textile element can be connected directly to the rod-shaped handle. The interposition of a mop holder with separately provided mop covers deleted. If the mop cover is changed, the handle is released from the mop 20 and not the insert 68 is removed from the textile element 52. The firm integration of the insert 68 in the textile element 52 can also be expressed by the fact that the textile element 52 is sewn tightly around the insert 68, so that after the original production of the user no longer remove the insert 68 from the pocket-shaped textile element 52 can. Alternatively, it is also possible to laterally one

To provide insertion pocket 70, which is indicated in Fig. 10 and shown in Fig. 11 in addition. However, the insertion pocket 70 should be arranged so that after releasing the handle from the attachment elements of the drawer not automatically, but only after the exact displacement and positioning within the pocket of the textile element 52 can be removed from this again.

With the present invention, a hand-operated cleaning device and a mop cover suitable in a special way has been proposed, which in the context of a modular

Systems can be used. The mop cover can be replaced with other cleaning heads and it is in all cases only a rod-shaped handle to connect to the cleaning head. The provision of a connection with at least one pair of permanent magnets also makes it particularly easy to attach the handle to the cleaning head. Even untrained and inexperienced

Cleaning personnel can immediately make the right connection, because the magnets have a self-centering effect and positioning inaccuracies can be compensated in this way.

The mop cover according to the invention can be attached directly to the handle. There is thus a hold-free mop. So that the mop cover is sufficiently dimensionally stable depending on the intended use, this can be done either via the in the

Producing the mop cover used textile fibers done or else on the provision of suitable

Stiffening elements, which are located around the interior of the pocket-shaped mop cover. The provision of suitable fibers and the additional provision of stiffening elements can also be used in combination. The stiffening elements can either be independent of the Anbrxngungselementen of the

Mop cover be provided, or else be provided integrally with these, to the final assembly to less

To reduce items. As a result, the provision of stiffening elements does not change the fact that the

Changing the mop cover no longer the mop cover must be solved by a mop holder and a new mop cover must be clamped to the mop holder, but only the mop cover as a whole must be released from the handle and replaced with a new one.
