Description

Cleaning device, mop cover cloth and cleaning system

Technical Field

The invention relates to a cleaning device comprising a mop plate having a central element articulated to a handle, a first oscillating wing and a second oscillating wing, wherein the first oscillating wing and the second oscillating wing are articulated to the central element and can oscillate between a mop position and a receiving position; in the wiping position, the first oscillating wing rests against the first main side of the central element and the second oscillating wing rests against the second main side of the central element; in the receiving position, the first and second swing wings hang down from the central element, which is provided with a latching member to latch the first and second swing wings in the wiping position. The invention also relates to a mop cover for a cleaning device and a cleaning system.

Background

A cleaning device for cleaning floors is known from EP 0757903 a 2. This cleaning device has a mop plate for receiving a mop cloth, wherein the mop plate is formed by a central oscillating element, on one side of which a handle holder is arranged in an articulated manner, and on the opposite side two oscillating wings which can oscillate opposite one another are arranged. Wherein the pivoting wings can be pivoted freely about a common pivot axis on the central pivoting element.

The pivot wing has freely movable long sides which are designed to engage in recesses on the long sides of the mop cover opposite each other. In this way, the mop cover can be received by the pivot wing, wherein after the pivot wing has been snapped into the recess, the central pivot element is first pivoted on the mop cover to the inside of one of the pivot wings and is releasably connected to this pivot wing. Subsequently, the unit consisting of the pivoting wings and the central pivoting element is pivoted to the inside of the second pivoting wing and releasably connected to this second pivoting wing. In this way, a mop plate is formed which receives a mop cover cloth, wherein the mop cover cloth is arranged on two mop surfaces which are opposite to each other.

Disclosure of Invention

The object of the invention is to further develop the cleaning device such that a particularly simple operation is achieved.

The solution of the invention to achieve the above object is characterized by the features of claim 1. Advantageous embodiments are described in the dependent claims.

To achieve the object, form-fitting elements for form-fittingly receiving a mop cover cloth are arranged on the edges of the first and second oscillating wings spaced apart from the central element. Such a cleaning device can reliably receive a mop cloth, wherein the mop cloth is reliably fixed to the mop plate during the cleaning process.

Preferably, in the wiping position, the form-fitting elements of the first and second oscillating wings snap into the latching member of the central element. Therefore, the mopping sleeve cloth fastened on the mopping plate can be fixed at the mopping position in a shape matching and loss prevention manner.

In the receiving position, the first and second swing wings may depend from the central element such that the mop plate is Y-shaped in side view. In this embodiment, the distance between the two long edges spaced apart from the central element is reduced, so that the mop cover can be received particularly easily.

The form-fitting element may be constructed in the form of a tongue. In this solution, the tongue extends from two edges spaced from the central element in the opposite direction to the central element. Viewed from a top view, according to a first solution, the tongue can be configured to be rectangular. Furthermore, according to another solution, the free end of the tongue may be rounded. By means of the rounded tongue, the oscillating wing can penetrate into the mop cover cloth more easily.

The tongue is designed to grip behind a corresponding form-fitting element of the mop cover in order to be able to fasten the mop cover to the two pivoting wings.

The tongue may be at least partially curved. If the two swing wings hang down in a Y-shape from the central element, the tongues, due to their curved solution, project laterally in the horizontal direction and are easy to insert into a mop cloth, which can be laid flat on the floor to be cleaned or in a transport container. In the transport container, in particular, a plurality of mop cloths can also be stacked one on top of the other in a horizontally oriented manner.

The first edge of the central element may be a swingably arranged swing axis for the first and second swing wings, and the latching member may correspond to an edge of the central element opposite to the first edge. Wherein the latching means snap-fit on an edge of the swing wing spaced apart from the central element and latch the swing wing in the mopping position such that the two swing wings rest on both main sides of the central element, wherein a mopping cover cloth is arranged on the other two sides of the swing wings such that the mopping cover cloth is likewise arranged on both main sides of the central element of the mopping plate.

The latching member at least partially loops over the form-fitting elements of the first and second oscillating wings in the mopping position. As a result, the two oscillating wings are securely fixed to the central element.

A snap-in member may be provided on a side of the form-fitting element facing away from the central element, wherein the snap-in member is configured to snap together with the latching member in the wiping position. This ensures a reliable locking of the oscillating wing.

The form-fitting element may correspond to the retaining member. If the form-fitting element is configured as a tongue, projections can be formed laterally from the tongue, for example, which form a hook-shaped contour. The retaining means can prevent uncontrolled release of the mop cover from the mop plate, in particular when the two swing plates are unlocked after the cleaning process has been completed in order to release the mop cover and collect it, for example, in a laundry bag.

The unlocking element can be at least partially designed to be elastic. Depending on the particular engagement of the handle with the central element, the mop plate for cleaning can either be pulled onto the floor to be cleaned or pushed onto the floor to be cleaned. If the mop plate is pushed, the edge of the central element spaced from the handle is located in the front, viewed in the direction of mopping. On this edge is also located a joint to which the swing wing is swingably engaged. In this position, the cloth of the mop cover is completely looped around the edge.

However, the mop plate can also be pulled. Wherein the edge corresponding to the handle is located at the front, seen in the wiping direction. In the mopping position, this edge is not completely covered by the mopping cloth, but is partially open. In order to prevent damage to the objects due to the mopping movement and the stop of the mopping plate, the elements of the edge which may protrude beyond the mopping cloth are advantageously constructed to be elastic. This is the case for example with a blocking member. In order to achieve a resilient solution, the blocking element can be made of a thermoplastic elastomer, for example. It is also possible to manufacture the latching member with a form-stable core and an elastic jacket by two-component injection molding.

The latching member may correspond to an unlocking element. The unlocking element makes it possible to quickly and simply release the mop cover from the plate. In a simple embodiment, the unlocking element can be in the form of a tab which is opened by simply pulling the locking element, so that the pivoting wing can be moved away from the central element. The unlocking element is preferably also elastic and is made, for example, of a thermoplastic elastomer. The actuation of the pulling movement on the tab for unlocking the locking element is advantageous, since the user can perform a movement directed away from the mop cover that is soiled as a result of the cleaning process. In addition, the user can be prevented from inadvertently touching the mop cover cloth when the mop cover cloth is detached from the mop plate. Thereby, the operation of the mop is particularly hygienic, in particular after the cleaning process. The unlocking element is preferably also elastic and is made, for example, of a thermoplastic elastomer.

It is also an object of the invention to provide a mopping cloth which is particularly simple to operate.

This object is achieved by the features of claim 10. Advantageous embodiments are described in the dependent claims which are incorporated back.

In order to achieve the object defined above, the mop cover comprises a planar layer which on one of its surfaces forms a mop surface and on the other surface has receiving elements for form-fitting contact with form-fitting elements of a mop plate, wherein the receiving elements are formed by strip-shaped strips which are arranged spaced apart from one another and parallel to one another on opposite edges on the receiving surface, wherein the strip sections are fastened to the layer, wherein through-holes for receiving the form-fitting elements of the mop plate are constructed between the strips and the receiving surface, wherein the form-fitting elements grip the strips from behind in order to fasten them to the mop plate.

In the mop cover according to the invention, the receiving element is formed in the form of a strip as a form-fitting element which corresponds to the form-fitting element of the cleaning device. Here, the strip sections are fastened to the layer. In order to fasten the mop cover to the cleaning device, the form-fitting elements of the swing wings of the mop plate, which hang in a Y-shape, are snapped into the corresponding through-holes, so that the form-fitting elements grip the band from behind in order to fasten it to the mop plate. Subsequently, the mop plate is pressed against the mop cover cloth by means of a vertical downward movement and is then pivoted in the direction of the first pivoting wing, so that the first pivoting wing engages in the locking element. The central element and the unit of the first pivoting wing which is locked in this way are then pivoted in the direction of the second pivoting wing, so that the second pivoting wing finally also engages in the locking member. Wherein the form-fitting element grips behind the strip of the mop cover cloth and protrudes through the through-hole, so that the mop cover cloth is reliably fastened to the mop plate and, in the process, covers the two main sides of the mop plate evenly and non-slip.

In this way, a cleaning system with mopping surfaces that can be used independently of one another is produced in a simple manner. The mop cloth is preferably designed in one piece. By means of the one-piece solution, during mopping, the mop cover cloth is placed around the mop plate in a U-shape and connected to the mop plate in a form-fitting manner. At the same time, the two mopping surfaces are firmly connected. The resulting fold line forms an elongate mop contour, by means of which, for example, skirting lines and small bosses can be cleaned without the mop plate having to be lifted from the floor.

Alternatively, the two mopping surfaces may be designed independently of each other. In this embodiment, the two mopping surfaces may be provided with different cleaning characteristics. For example, a mopping surface may be formed from a fluffy microfiber plush fabric to clean smooth floors with loose dirt. The opposite mopping surface may contain a woven strip with cleaning bristles to clean rough floors with tough stains.

The mop cover is preferably constructed so as to be flat and soft for shipping, washing and cleaning. Thereby, the mop cover can be transported as a loose single part and has a particularly advantageous geometry in order to be able to clean easily and thoroughly in machine washing with a minimum of washing chemicals, mechanical forces, time and water. In this case, both sides of the mop cover and all the fabric fastening elements can equally well be used in the washing process.

In the mop cover according to the invention, it is particularly advantageous if no recesses are required at all into which the oscillating wings at least partially engage. The mop cover cloth is fixed on the mop plate only by means of a strip. In this regard, the present invention is completely free of recesses or similar features that allow dirt to accumulate and be difficult to clean. In contrast to sewn grooves, the back side of the strip and the mop cover do not form any cavities, undercuts or grooves and can be rinsed particularly easily for cleaning, in particular in machine washing. This is advantageous in situations where a wiping blanket is required for use in a hygienically sensitive area.

Preferably, the planar layer of the mop cover is substantially rectangular in configuration and has two opposite narrow sides and two opposite main sides, wherein the strips are arranged in a parallel manner on the main sides. In most cases, the mop cover cloth, which is to be applied against one side of the mop plate for cleaning, has fastening elements which correspond to the narrow sides of the mop cover cloth. However, in the present wipe cover, the fastening elements (here, the strips) correspond to the major edges.

By designing the mop cover cloth as a planar structure and attaching the fastening element on only one side of the mop cover cloth, it is ensured that it can be manufactured in a very simple manner. The mop cover can be laid flat and worked from only one side during the entire manufacturing process. This allows a high level of automation to be achieved with simple components in the production.

The major side may correspond to a stiffener. The reinforcement can be made, for example, of a fabric strip which is fastened to the mop cover on the side facing away from the cleaning side. The reinforcement may also be in the form of a plastic strip, for example formed of a thermoplastic elastomer. The reinforcement improves the leveling and abutting of the mop cover cloth on the floor to be cleaned. In addition, it is prevented that in the case of particularly high friction, the mop cover cloth is pushed partially under the mop plate, so that the front edge of the mop plate is exposed.

The cleaning system of the invention comprises a cleaning device and a mop cover cloth, wherein in the mopping position, form-fitting elements of a first oscillating wing and a second oscillating wing of the mop plate snap into through-holes between the strip and a receiving surface of the mop cover cloth, and wherein the first oscillating wing and the second oscillating wing are oriented parallel to the central element, and wherein the mop cover cloth substantially covers the surfaces of the first oscillating wing and the second oscillating wing facing away from the central element.

If the form-fitting element is constructed as a tongue, the tongue can be passed through the through-hole of the strip in such a way that the strip rests between the tongues on the edge of the oscillating wing. The mop cover cloth can thereby be fixed particularly reliably to the mop plate, and the cleaning process is particularly efficient.

In this connection, it is particularly advantageous if, in the wiping position, the free end of the form-fitting element snaps into the latching member. In this case, the strip of the mop cover cloth is fixed between the base of the oscillating wing and the blocking member in such a way that the mop cover cloth cannot be released from the mop plate by itself. This is advantageous when cleaning very rough floors, where the high friction between the floor covering and the mop cover cloth creates a large force that tries to separate the mop cover cloth from the mop plate.

The mop plate and/or the mop cover cloth may correspond to at least one additional securing member. In this case, according to a first aspect, the mop cover and the mop plate can correspond to magnetic elements which, after the mop cover has been placed on the mop plate, are connected to one another and thus additionally fix the mop cover on the mop plate. Alternatively, additional securing members in the form of velcro or other form-fitting elements (e.g. buttons) may be provided. The free main edge of the mop cover opposite the U-fold in the mop position can additionally be fastened by means of its own fastening means in the form of velcro, zip, push button or the like.

Drawings

The technical solutions of the cleaning device, the mop cover and the cleaning system according to the present invention will be described in more detail below with reference to the accompanying drawings. The figures show schematically:

fig. 1 is a perspective view of the cleaning system.

Detailed Description

The cleaning device 1 comprises a mop plate 2 having a central element 3 articulated with a handle 4. The central element 3 is articulated to the shank 4 by means of a universal joint 13.

The mop plate 2 further comprises a first oscillating wing 5 and a second oscillating wing 6, wherein the first oscillating wing 5 and the second oscillating wing 6 are joined to the central element 3 in an articulated manner. In order to arrange the oscillating wings 5, 6 in an oscillating manner, an oscillating shaft for receiving the first oscillating wing 5 and the second oscillating wing 6 is arranged on the first edge of the central element 3.

Wherein the first swing wing 5 and the second swing wing 6 can swing between a wiping position and a receiving position. In the wiping position, the first swing wing 5 rests against a first main side 7 of the central element 3 and the second swing wing 6 rests against a second main side 8 of the central element 3. In the receiving position, the oscillating wing 5 and the second oscillating wing 6 hang in a Y-shape, seen in side view, from the central element 3.

The central element 3 is provided with a latching member 9 to latch the first swing wing 5 and the second swing wing 6 in the mopping position. In the present invention, the blocking means 9 is constructed in the form of a blocking rod and corresponds to the edge of the central element 3 facing the universal joint 13. The locking member 9 extends substantially over the longitudinal extension of the rim. The blocking member 9 is provided with a resilient element which automatically brings the blocking member 9 into the blocking position.

On the edge 10 of the first and second oscillating wings 5, 6 spaced apart from the central element 3, a form-fitting element 11 is arranged for the form-fitting reception of a mop cover 12. The form-fitting element 11 is also configured to snap into the latching member 9 in the mopping position to latch the first and second oscillating wings 5, 6 there in a manner abutting on both sides against the central element 3.

The form-fitting element 11 is constructed in the form of a tongue 11', wherein the tongue 11' is at least partially bent such that it projects in a horizontal direction transversely to the suspended central element 3 in the receiving position.

In the wiping position, the blocking member 9 loops over the form-fitting elements 11 of the first and second oscillating wings 5, 6. The blocking member 9 is made of a form-stable plastic and is thus rigid in the longitudinal direction. The locking member 9 also corresponds to an unlocking element 15, which is connected to a lug projecting in the direction of the universal joint 13. The tab is made of a thermoplastic elastomer and is elastic. If the tab is pulled, the latching member 9 releases the form-fitting element 11, so that the oscillating wing 5, 6 can be moved from the wiping position into the receiving position.

The mop cover cloth 12 of the invention comprises a planar layer 16 which on one surface 17 thereof forms a mop surface and on the other surface 18 has a receiving element 19, which receiving element 19 is intended for form-fitting connection with the form-fitting element 11 of the mop plate. The planar layer 16 of the mop cover 12 is generally rectangular in configuration and has two opposing

narrow sides

24, 25 and two opposing major sides 26, 27.

The receiving element 19 is formed by strip-shaped strips 20 which are arranged spaced apart from and parallel to each other on

opposite edges

21, 22 on the other surface 18. In the present solution, the

opposite edges

21, 22 correspond to the main edges 26, 27. Correspondingly, the strip 20 corresponds to the main edges 26, 27.

The strip 20 is fastened in sections on the layer 16, wherein a through-hole 23 for receiving the form-fitting element 11 of the mop plate 2 is constructed between the strip 20 and the further surface 18. In the present solution, the strip 20 is fastened to the plane layer 16 by means of seam sections. The sections of the strip 20 form through-holes 23 between the seams, through which the form-fitting elements 11 of the mop plate can be snapped in.

The main sides 26, 27 correspond to reinforcements 28 in the form of fabric strips sewn onto the planar layer 16.

As previously mentioned, the cleaning system 30 of the present invention comprises a cleaning device 1 and a mop 12. In the mopping position, the form-fitting elements 11 of the first and second oscillating wings 5, 6 of the mopping plate 2 snap into the through-holes 23 between the strip 20 and the other surface 18 of the mopping blanket 12. Wherein the first and second oscillating wings 5, 6 are oriented parallel to the central element 3 and the wiping cloth covers the surfaces of the first and second oscillating wings 5, 6 facing away from the central element 3.

In an alternative embodiment, the mop plate 2, preferably the pivoting wings 5, 6 and the mop cloth correspond to an additional fastening means. Magnets are preferably used here, which additionally fix the mop cover 12 to the mop plate 2 in the mop position.
