Description

The invention relates to a cleaning set for cleaning a surface, preferably for cleaning a floor, comprising at least one base plate with an upper side, on which a coupling point for a handle is arranged, and an underside facing away from the upper side, wherein the base plate has a diamond-shaped outline, and at least one mop textile cover.

Cleaning sets with a mop, base plate and, if necessary, a handle are everyday objects that are used for cleaning purposes both privately and commercially. The mop in the cleaning set is used for (often wet) cleaning of smooth floors. There are already plenty of cleaning sets designed for private use, e.g. including a bucket and mechanism for rinsing and wringing out the mop. These cleaning sets are often used, but from a hygienic point of view they are unsuitable, at least in buildings such as hospitals, old people's homes, etc., because the mop does not really get clean when rinsed and is wiped with dirty water for a long time. On the one hand, the conditions in such buildings are usually completely different, i.e. there is usually a greater and more complex degree of dirt. In addition, the areas are usually larger and there is less time available or the workers are given less time. On the other hand, in the commercial environment the focus is unfortunately more on quantity than on quality. Unfortunately, this is also due to the way in which staff are usually paid, namely according to the area cleaned. The workers themselves are then primarily interested in taking as little time as possible to cover as much work area as possible. If staff are paid on an hourly basis, the employer is primarily interested in the cleaning process being as quick as possible and thus as much area as possible being cleaned in as short a time as possible. Regardless of this, there is always an interest in providing a cleaning set in which the time required to change the mop between the actual cleaning times is minimized as much as possible. This is because the actual cleaning time required to clean an area can only be reduced to a certain extent (otherwise the quality suffers enormously).

Nowadays, in commercial cleaning, e.g. cleaning hospital floors etc. (if the cleaning is done professionally), the mop or a mop textile cover is usually washed directly by a fresh mop textile cover. Only then are the collected, used mop textile covers effectively cleaned together in a cleaning system, e.g. a washing machine, by washing them with hot water and disinfecting them if necessary. This procedure has proven to be far more hygienic than having the mop textile covers washed several times by the cleaner themselves and then reusing them.

This is why standard cleaning sets with a bucket for washing and a mechanism for wringing are generally not suitable for commercial cleaning. In most cases, changing the mop is either time-consuming due to the design, as the mop does not actually have to be removed from the holder for washing and wringing, or the mop is permanently attached to the holder.

It is therefore an object of the present invention to provide a cleaning set which enables a particularly quick and uncomplicated changing of the mop textile cover, if necessary of another cleaning attachment, in particular with only one hand in one movement.

This object is achieved by a cleaning set according to patent claim 1.

As mentioned at the beginning, the cleaning set for cleaning a surface, preferably for cleaning a floor, comprises at least one base plate with an upper side on which a coupling point for a handle is arranged. Cleaning or purifying is also understood here to mean disinfecting, wiping, dry wiping or, for example, applying a liquid, such as a cleaning liquid, to a surface.

It should also be noted at this point that although the cleaning kit is always described below in relation to cleaning a floor, it can also be used, for example, to clean a wall, table or ceiling surface.

The base plate also includes a bottom side facing away from the top side. The base plate has a diamond-shaped outline. The diamond-shaped outline includes a closed contour, ie no indentations or the like. The diamond-shaped The floor plan is preferably a rhombus with two acute and two obtuse interior angles, i.e. two acute-angled corner areas and two obtuse-angled corner areas.

The two acute-angled corner areas are preferably located opposite each other at the ends of a longer first diagonal (also called "long diagonal") of the rhombus and the obtuse-angled corner areas are located opposite each other at the ends of a shorter diagonal (also called "short diagonal") running transversely, preferably perpendicularly, to the first diagonal. The base plate is preferably mirror-symmetrical with respect to both diagonals.

Preferably, the interior angles of the acute-angled corner areas of the base plate can be no more than 30°. This slightly extends the edge length of the base plate compared to a standard square base area, so that a user can always reach into the corners when cleaning room floors or the corner steps of spiral staircases. This means that the edges of the base plate taper towards each other in this acute-angled corner area right to the end and the tip formed is not rounded (apart from a minimal rounding angle that is unavoidable within the usual tolerance for production reasons but is negligible in terms of the desired function of cleaning corners). This acute-angled diamond-shaped outline preferably affects both the base plate itself and the mop textile cover as well as all accessories and cleaning attachments, which are explained further below.

As already mentioned, the cleaning set also includes a mop textile cover for picking up dirt on the floor with a diamond-shaped textile base. The diamond-shaped textile base is adapted to the diamond-shaped outline of the base plate. This means that it is almost the same size and can be slightly larger if necessary so that it can be at least partially placed or pulled over the base plate.

Accordingly, the interior angles of the acute-angled corner areas of the textile base area should preferably be no more than 30°. The tapered or acute-angled corner areas ensure that the base plate and the mop textile cover do not completely fill a right-angled corner when cleaning it. Completely filling a corner when cleaning would be disadvantageous in practical use, as a dynamic wiping movement would then no longer be possible. Since a diamond has this acute angle on two sides, it is possible to quickly switch between the sides. so that both sides can be used for cleaning and in this way, for example, two such corners can be cleaned very dynamically one after the other.

In the simplest case, the mop textile cover is a cleaning cover or cloth with fringes or loops. The cleaning cover can have any fringes or loops, short or long, to pick up dust on the floor. It can also be moistened or used completely wet for more effective floor cleaning. Accordingly, it is also referred to as a mop textile cover or wiping cloth.

Alternatively or in addition to the textile mop cover, the cleaning set includes an additional cleaning attachment that can be connected to the underside of the base plate. Details of this will be described later.

To ensure that the mop textile cover always remains on the base plate during use, the base plate preferably has at least one adhesive element on the underside. This adhesive element can preferably be a Velcro element, i.e. usually a hook strip to which the mop textile cover then adheres. The adhesive element can particularly preferably be injected in the form of (small) hooks, spikes, etc., e.g. if the base plate is manufactured using an injection molding process. The material of the mop textile cover can then be selected accordingly, which is suitable in most cases anyway, or an additional fleece strip can be sewn in as a counter Velcro element, as explained below.

Preferably, the mop textile cover can have a counter-adhesive element complementary to the adhesive element, in particular a counter-Velcro element, which is at least partially, preferably completely, integrated (in the top side) into the mop textile cover. Preferably, the counter-Velcro element can be woven into the mop textile cover. The counter-adhesive element, in particular the counter-Velcro element, can also be made up of several parts.

Preferably, the mop textile cover can therefore comprise at least one suitable counter-adhesive element on an upper side. This can accordingly particularly preferably be a counter-Velcro element, ie when the Velcro element is a hook strip is a fleece strip and vice versa. The top side here refers to the inside that faces the base plate during normal use or application, which then rests against the underside of the base plate.

The mop textile cover can also have such a counter-adhesive element, in particular a counter-Velcro element, on an upper side, for example preferably over the entire surface or at least essentially over the entire surface, for example except for a (narrow) edge area, or can be designed on the upper side as such a counter-adhesive element, in particular a counter-Velcro element. The dimensions of the adhesive element, in particular the Velcro element, on the underside of the base plate can preferably be selected to suit this.

Alternatively or additionally, the mop textile cover can have an insertion loop and/or insertion pocket for a first acute-angled corner area of the base plate on at least one first acute-angled corner area of the diamond-shaped textile base on an upper side, in particular for receiving the corner area. This means that the mop textile cover can therefore be sewn there in the form of a textile insertion loop and/or insertion pocket, for example.

Furthermore, the mop textile cover can have a first quick-release element or a second insertion pocket for a detachable coupling to the base plate on at least a second corner area of the diamond-shaped textile base area. The detachable coupling to the base plate preferably takes place on a second acute-angled corner area of the base plate.

Preferably, the mop textile cover can have a first quick-release element or a second insertion pocket for a detachable coupling to the base plate at a second acute-angled corner region of the textile base, which is opposite the first acute-angled corner region of the textile base.

Preferably, the base plate can have a counter-coupling element for the quick-release element in a second acute-angled corner area. This design has the advantage that the quick-release element remains particularly securely attached to the base plate even if the base plate is frequently lifted from the ground, for example to clean or polish steps or similar.

To clean a normal flat floor, the cleaning set can generally manage without such a special counter-coupling element for the quick-release element during cleaning. This is because the base plate usually only needs to be lifted to attach and change the mop textile cover. In this case, it may therefore be sufficient to simply loop the quick-release element, for example if it is designed as an elongated piece of material, namely tape, cord, string or the like (as explained in more detail below), once or several times around the relevant acute-angled corner area of the base plate for a somewhat faster (but not completely fixed) attachment to the base plate, so that the mop textile cover remains securely on the base plate in its intended cleaning position, at least when it is in contact with the floor or is only slightly lifted.

The two acute-angled corner areas, i.e. the first acute-angled corner area and the second acute-angled corner area, are the two corner areas of the four corner areas of the diamond-shaped textile base area in which the interior angles between the outline edges or side lengths are smaller than in the other two corner areas. "Acute-angled" also means that the diamond-shaped base area has two acute interior angles there and, accordingly, obtuse interior angles in the other two corner areas. Preferred values for the acute interior angles will be mentioned later in a preferred embodiment of the invention.

Alternatively or additionally, the base plate can be assigned a holding plate that can be detachably coupled to the underside of the base plate. The holding plate (e.g. only a few millimeters thick) has at least one holding element for detachably coupling the mop textile cover to the holding plate. The holding element is particularly preferably arranged on an underside of the holding plate, which - when the holding plate is coupled to the base plate - points away from the base plate. Most preferably, the holding element can also be at least partially, in particular completely, integrated into the holding plate. For example, the holding element can be integrated into the underside of the holding plate. The holding element can preferably be injection-molded when the holding plate is manufactured using an injection molding process. For example, small hooks, spikes or similar can be injected or formed, which then also hold the mop textile cover against slipping when the surface is cleaned.

Regardless of the specific embodiment, the holding element can also be designed in several parts.

The construction according to the invention ensures the necessary adhesion, e.g. relative static friction between the base plate and the mop textile cover. This means that the mop textile cover stays particularly well in the intended position on the base plate during the cleaning process, e.g. during dynamic movements on the floor surface, when lifting perpendicular to it, e.g. when the mop textile cover has to be lifted over a threshold in order to clean the next room or further steps, or e.g. when a contamination on the floor, such as a sticky spot, causes increased friction.

On the other hand, the mop textile cover can also be attached to the base plate very easily and quickly and removed just as quickly and easily for changing.

The cleaning set according to the invention is therefore a particularly simple and quick-to-change cleaning set that is ideal for commercial use. It therefore enables time to be saved when cleaning floors, which results from the particularly quick and easy change of the mop textile cover, or a different cleaning attachment if necessary. Whereas, with designs known from practice, time is lost when changing the mop textile cover, the design according to the invention can save time, which in turn is then available for cleaning other floor areas.

Furthermore, the diamond-shaped outline with acute-angled corner areas also helps to effectively clean tight corners on the floor right into the very back of the corner. Furthermore, the diamond-shaped outline with acute-angled corner areas helps to clean narrow places, e.g. between chair or table legs, etc. with ease without bumping into anything, as the acute-angled corner area can be threaded into the narrow gap or guided along the object in question without bumping into anything with a broad side (e.g. with rectangular or square base plates).

If the cleaning set is designed with corresponding adhesive elements as described above, the mop textile cover can be attached to the base plate particularly quickly and easily, essentially with just one hand in one quick movement. This saves a lot of time, additional handling and is also much more hygienic. If the mop textile cover is arranged on the base plate via a pocket and e.g. a quick-release element or by means of a holding plate, the mop textile cover can be changed quickly and easily. This means that The invention is particularly suitable in the field of commercial cleaning, since here time is of paramount importance and saving time means saving costs.

Furthermore, the construction according to the invention, in particular the base plate with mop textile cover, can have such a low structural height that, if possible, only the surface to be cleaned itself is cleaned or wetted, but not a boundary surface such as an adjacent wall surface or an adjacent part of the building. This is advantageous, for example, when applying, i.e. coating or sealing, e.g. with cleaning agents, polymer coatings, etc. In practical terms, no adjacent boundary surfaces need to be taped off when applying a cleaning agent or polymer coating, etc.

Further, particularly advantageous embodiments and developments of the invention emerge from the following description, wherein in particular individual features of different embodiments or variants can be combined to form new embodiments or variants.

There are various options for anchoring or relative fastening between the base plate and the mop textile cover:
Preferably, the first quick-release element can comprise a flexible, elongated piece of material, such as a band, a cord, a string or a tab, preferably a textile tab.

The base plate can preferably have anchoring means on its upper side, preferably as a counter-coupling element, for the flexible, elongated piece of material. Anchoring means here means all means that can be used for anchoring. These can particularly preferably be arranged in the corresponding second corner area of the base plate assigned to the second corner area of the textile base area, in particular in (cleaning) operation.

The base plate can preferably comprise a cleat on its upper side as an anchoring means for the flexible, elongated piece of material. This can preferably be arranged in the corresponding second corner area of the base plate associated with the second corner area of the textile base area.

Particularly preferably, the base plate can even include two fastening pins or "fastening nipples" as anchoring means for the piece of material. These can, for example, protrude slightly upwards or away from the base plate so that a user can very easily and quickly tie, secure or anchor the flexible, elongated piece of material to it.

However, it is also possible that instead of two fastening pins that are physically spaced apart from one another, only fastening pins that are at least diagonally spaced apart or diverge from one another are used, which are spaced apart from one another in at least one anchoring area. This means that the flexible, elongated piece of material for anchoring can still be easily tied or laid around the "individual" fastening pins.

For simple and quick, but at the same time sufficiently secure anchoring to a cleat or two such fastening pins, a so-called "Dopino" knot is suitable, i.e. a started belay knot with a half hitch at the end (the other way round to a normal head hitch). Such a knot can be tied very quickly in a very simple but effective way and can be untied just as quickly.

Alternatively or additionally, the fastening pins can also be designed to be slip-resistant, for example by being provided with a slip-resistant coating or by having an external shape that ensures that, for example, an elongated, flexible piece of material slips as little as possible on them or does not slip off them when it is wrapped around them.

The first quick-release element can preferably comprise a tab. In other words, it can be designed like a band, preferably so wide that when the tab is pulled upwards over a tip of the relevant acute-angled corner area of the base plate, the tab envelops the tip. The tab can preferably be a textile tab or textile flap. This ensures a certain flexibility and makes it easier to attach, e.g. by sewing.

Preferably, the tab can have a Velcro tab for a counter-Velcro element arranged on the upper side of the base plate.

In this case, the counter-Velcro element, e.g. a hook strip, can be arranged particularly preferably on the top in the area of the second acute-angled corner area of the base plate. This serves to attach the Velcro tab, which in this case could then be a fleece strip, for example, which adheres to the hook strip.

Preferably, the first quick-release element can comprise an elastically extendible loop which can be pulled or pulled over at least one acute-angled corner area of the base plate for fastening to the base plate. The loop, e.g. an elastic band or an elastic band or similar, can in turn be sewn onto the associated acute-angled corner area of the mop textile cover in an area slightly spaced from the tip, i.e. not right at the front of the tip, i.e. slightly further inwards parallel to the short diagonal of the mop textile cover.

Preferably, the loop, in particular also the respective insertion pocket, is arranged on an upper side of the mop textile cover, in particular the textile base surface, which is opposite a cleaning surface (as underside) of the mop textile cover.

Preferably, the mop textile cover can be provided with an insertion band on a half-side or half having the insertion loop and/or insertion pocket, which connects the two contour edges connected by the insertion loop and/or insertion pocket on the inside in the acute-angled corner area of the diamond-shaped textile base at a position between the insertion loop and/or insertion pocket and the short diagonal of the diamond-shaped textile base. The insertion band is preferably arranged on the top of the mop textile cover or spans the top of the textile base. The insertion band therefore bridges the textile base and thus forms a holding loop for threading the mop textile cover relative to the base plate.

Preferably, the insertion band can extend perpendicular to a longitudinal direction of the mop textile cover, ie parallel to the short diagonal of the mop textile cover. The short diagonal is the shorter of the two diagonals, in this case the diamond-shaped textile base area. A position approximately in the middle between the tip of the relevant acute-angled corner area and the short diagonal is particularly preferred, very particularly preferably closer to the short diagonal or the diagonal intersection point than to the tip.

There are various options for further equipping the cleaning set.

Preferably, the above-mentioned additional cleaning attachment can be detachably coupled to the base plate by means of at least one second quick-release element.

Alternatively or additionally, the holding plate can be detachably coupled to the base plate by means of at least one second quick-release element.

The cleaning attachment and/or the holding plate can preferably have a plate-like, diamond-shaped base surface which is adapted to the diamond-shaped outline of the base plate.

Preferably, the additional cleaning attachment can comprise at least one of the following elements, namely a brush plate, a sponge element or a pad plate. Preferably, the additional cleaning attachment can be detachably coupled to the base plate as an alternative to a mop textile cover in order to form a (ready-to-use) cleaning set.

A brush plate or bristle plate is a plate with brushes or bristles that can be used to clean stubborn, coarse dirt on the floor. A sponge element is a plate or cube-shaped cleaning attachment containing a sponge that can be used, for example, on more sensitive floors to absorb moisture or to moisten. The sponge can also be a glass ceramic sponge for removing grease and stubborn dirt, such as burnt-on dirt.

A pad plate here refers to a pad - such as a scrubbing pad, a microfiber pad, a hand pad, a polishing pad or similar - which is arranged on a plate.

There are preferred options for attaching such a cleaning attachment and/or the holding plate to the base plate.

Preferably, the second quick-release element on the base plate can have at least one through-hole that goes through the base plate. Through here means completely through the base plate from the top to the bottom.

Furthermore, the second quick-release element can comprise at least one coupling element in order to couple the further cleaning attachment and/or the holding plate to the bottom of the base plate through the through-hole.

Particularly preferably, the base plate can have two through holes through the base plate in order to be able to couple the additional cleaning attachment and/or the holding plate at two positions evenly distributed over the base plate. For example, the principle of a clamp closure with a cap lifter (as used to close glass bottles) could be used for the coupling.

In a preferred variant, the coupling element can be designed as a screw element, e.g. as a wing screw or threaded rod with a wing nut. For this purpose, the cleaning attachment and/or the holding plate can preferably also be designed with corresponding internally threaded holes.

In a particularly preferred variant, the cleaning set comprises two wing screws, a base plate with two, preferably four, through holes for the variable attachment of the two wing screws and the additional cleaning attachment and/or the holding plate two threaded holes for screwing in the wing screws.

Preferably, the holding element of the holding plate can have an adhesive element, in particular a Velcro element. The adhesive element, in particular a Velcro element, can be designed, for example, in the form of a plate or film, i.e., only a few millimeters thick, in order to attach the mop textile cover to it and to hold it in the attached position when cleaning the floor.

Alternatively or additionally, at least 30%, preferably at least 50%, particularly preferably at least 75%, of an underside of a base area of the holding plate can have a holding element. In principle, the underside of the holding plate can also be designed essentially completely as a holding element, in particular as an adhesive element. Accordingly, the mop textile cover then adheres at least partially to the holding plate, and adheres (over the entire surface) wherever an adhesive element is located. For this purpose, the adhesive element can, for example, have a surface facing the mop textile cover in the coupled state with a hook surface with a large number of hooks or barbs.

These then hold the material of the mop textile cover firmly in place after a light press, whereby a certain position between the holding plate and the mop textile cover is maintained, particularly during (cleaning) operation. To change the mop textile cover, it can then simply be pulled off or detached from the adhesive element again by applying a little pulling force in a rolling motion along the holding plate, for example in the same way that you pull a Velcro strip, adhesive tape or film off a Velcro or adhesive surface. This advantageously enables the mop textile cover to be easily disassembled and assembled, whereby a secure, temporary attachment of the mop textile cover to the base plate (via the holding plate) is achieved.

If the holding plate is manufactured using an injection molding process, as is preferred, it is also possible to integrate the holding element into the holding plate, or more precisely into the underside of the holding plate, i.e. to form it or to inject it. For example, a hook surface with a large number of hooks can also be integrated into the underside of the holding plate.

As mentioned above, there is a coupling point for a rod in the top of the base plate, i.e. any element that enables the base plate to be coupled to a rod. In principle, this coupling point can be designed in any way, provided that a corresponding counter-coupling element, e.g. a suitable adapter, is arranged at the (lower) end of the rod that is to be coupled to the base plate.

For example, in a preferred variant, a handle can also be arranged on the top of the base plate. This can be particularly advantageous when used to clean a wall, table or ceiling surface. Such a handle can preferably have at least one handle opening and/or at least one grip recess. For example, the handle can extend in an arc (so that the handle opening remains below the arc) in a longitudinal direction that preferably runs parallel to one of the diagonals above the base plate, particularly preferably parallel to the longer diagonal.

The handle itself can, for example, serve as a coupling point for a handle if it has a suitable receiving element or an adapter (for example a clamping device for clamping the handle). In particular, the handle can also be designed in such a way that it has a coupling element specially provided for this purpose, for example a coupling eyelet (a coupling hole or a coupling bore), in which, for example, an axle or at least an axle stub or a pin can be inserted into a counter-coupling element or adapter at the end of a handle.

Such a coupling eyelet can preferably be arranged in such a way that a (virtual) coupling axis runs through the coupling eyelet, along which, for example, an axle or the said axle stubs or pins can be inserted on an adapter at the end of a handle, transversely to the handle, particularly preferably perpendicular to a longitudinal extension of the handle and parallel above the top of the base. An example of a suitable adapter for coupling a handle with such a coupling eyelet is given, for example, in the EN 10 2019 113 870 A1 described. This has a U-shaped, fork-like holder with two fork arms at the lower end, of which two short pins or axle stubs opposite one another extend inwards into the fork space on a common (virtual) axis. This fork-containing holder is made of a material (in this case, plastic) that allows the fork arms to be easily pushed apart so that they clamp the handle between them on the top of the base plate, with the pins or axle stubs engaging the coupling eyelet on the handle from both sides. This holds the handle securely on the adapter, which can still be pivoted around the virtual axis of the coupling eyelet. The upper part of the adapter can also be used, for example, as in the EN 10 2019 113 870 A1 designed to fit different stem diameters.

Preferably, the cleaning set can comprise a coupling mechanism arranged at the coupling point of the base plate, which connects the base plate to the handle. The coupling point can be located (viewed in a projection from above onto the top of the base plate) particularly preferably at the intersection point of the diagonals of the diamond-shaped outline.

The coupling mechanism can be designed in such a way that the stem can be pivoted relative to the base plate by at least two degrees of freedom. For example, it is a joint with at least two axes or a double joint or a ball joint.

Particularly preferably, the cleaning set can comprise a fork joint, a joint cube that can be rotated in the fork joint about a fork joint axis and has fork joint receiving holes in at least two of its side surfaces, and an adapter that can be coupled to the joint cube with another fork joint and has an interface for a handle. The The adapter can be rotated in the additional fork joint about a second fork joint axis. This means that the handle or the base plate, e.g. with the mop textile cover on the handle, can be positioned almost anywhere in two degrees of freedom.

Preferably, the cleaning set can comprise a generally elongated handle as a grip and extension for convenient holding and guiding of the cleaning set by a user and an adapter for fastening the base plate to the handle with an adapter element. For this purpose, the adapter element preferably has a conical fitting section for forming a positive connection with one end of the handle and a conical threaded section.

With such an adapter element of the adapter, different standard pipe stems or stems on the adapter can be attached to the base plate and used.

If an adapter is to be used for coupling with the handle, which is to be coupled to a coupling eyelet of a handle described above, which allows the base plate to be pivoted relative to the handle by several degrees of freedom, this adapter can of course also have a corresponding coupling mechanism, for example by connecting the EN 10 2019 113 870 A1 a joint cube is used, similar to what was previously described.

In order to achieve a coupling of the handle with a handle on the upper side of the base plate that can be pivoted about two (pivoting) axes, in another preferred variant the handle itself can also have at least one pivoting part, i.e. a pivot axis can be integrated into the handle.

For example, the handle could have a simple coupling eyelet running across the handle, with which, as described above, a U-shaped, fork-like holder (as in the EN 10 2019 113 870 A1 ) of an adapter at the end of a handle. This coupling then allows the handle to be pivoted on the handle about a first pivot axis, namely the longitudinal axis through the eyelet. In order to allow pivoting of the handle relative to the base plate about a second pivot axis that is transverse, preferably perpendicular, to this first axis, the handle can be made up of several parts. A part that contains the coupling eyelet can be pivoted relative to the other parts of the handle.

Particularly preferably, an arcuate handle can be divided into at least three sections along its length, with the coupling eyelet located in the middle section. This middle section is then pivotably coupled to the two outer sections of the handle about a pivot axis running in the direction of the length of the handle (which then forms the second pivot axis), which in turn are each firmly connected to the top of the base plate. It is preferably also possible for the middle section of the handle to be lockable between the two outer sections of the handle in a basic position in which the axis runs through the coupling eyelet parallel to the top of the base plate, for example by means of suitable locking means. With a slightly increased effort and/or by actuating an integrated release device (e.g. pressure on a locking spring or the like), it can be pivoted out of this basic position (again).

Preferably, the underside of the base plate can be flat and substantially planar over the entire contour, i.e. the entire contour length.

Because the base plate lies flat on the floor on the side facing the floor when used as intended (at least indirectly via the mop's textile cover), the base plate can apply even pressure to the floor over the entire length of the contour edges when cleaning. This significantly improves the cleaning result.

In particular, pressure can be effectively exerted in the area of the acute-angled corners of the diamond-shaped base plate.

Preferably, the base plate can comprise a diamond-shaped outer frame all around, between which a material-saving inner lattice structure with lattice struts for stabilization and stiffening runs or is formed.

Compared to a base plate made of solid material, this saves material and weight. However, the grid structure still provides the necessary stiffening and stabilization.

Preferably, the lattice structure can be designed such that the lattice struts converge in a star shape at three positions on one of the diagonals.

In a middle position of the three positions, they can form an overlapping, converging central surface, where the coupling point for a stem is located. In the two off-center positions, they can each form an overlapping, converging fastening surface, in each of which the through holes are made.

Preferably, at least the oblique lattice struts of the lattice structure can protrude from the frame or outer frame at the same angle, so that an overall uniform honeycomb structure is created.

Particularly preferably, the lattice struts can be hollow inside to save even more material and weight.

It should be noted at this point that a combination of the previously described embodiments is also possible. For example, a single base plate can be designed to detachably attach either another cleaning attachment or a mop textile cover to it.

a perspective exploded view from above of the embodiment according to Figure 7 .

In Figure 1 An embodiment of a cleaning set 1 according to the invention is shown by way of example and schematically in a perspective view of an upper side.

The main components of this cleaning set 1 include a base plate 10 with a diamond-shaped outline 10g, which has a coupling point 12 for an elongated handle 60 or an end 61 of the handle 60, the optional handle 60 itself and a mop textile cover 40 with a textile base area 40g that is also diamond-shaped and is adapted in shape to the base plate 10.

The base plate 10 is further constructed from a diamond-shaped outer frame 13, between which a grid structure 14 or grid struts 14 run. The grid struts 14 are evenly distributed so that they stabilize the structure evenly. The diamond-shaped outline 10g of the base plate 10, or more precisely of the outer frame 13, comprises two acute-angled corner areas 10a, 10b with an interior angle α ( Figure 4 ) and in between two obtuse-angled corner areas 10c, 10d ( Figure 3 ), which of course lie opposite each other due to the diamond shape. The respective acute-angled corner areas 10a, 10b are connected in a stiffening manner by a lattice strut in the longitudinal direction 55L along a long diagonal 57 and the respective obtuse-angled corner areas 10c, 10d are connected in a stiffening manner by a lattice strut in the transverse direction 55Q along a short diagonal 56. Between Hollow spaces are left in the lattice struts 14, so that the construction requires considerably less material than a base plate made of solid material and above all saves weight. In addition, the lattice struts 14 themselves are made hollow, which saves material and weight again.

In addition to the two diagonal lattice struts 14, further lattice struts 14 run diagonally (approximately at 45° angles) to the two diagonals 56, 57 within the outer frame 13. The diagonally running lattice struts 14 end in the two diagonals 56, 57 at three points, each at a 45° angle. At a central point, which forms the diagonal intersection point 58, this creates a reinforced central surface 12a for the coupling point 12. At the other two off-center points, approximately halfway between the diagonal intersection point 58 and the respective tip of the respective acute-angled corner areas 10a, 10b of the base plate 10, this creates a reinforced fastening surface 15a, 15b. Towards the outside, the lattice struts 14 running diagonally between the diagonals 56, 57 and the outer frame 13 run into the outer frame 13. The lattice-like construction or the lattice structure 14 thus saves material and weight, as mentioned, and is also extremely stable.

At this point, it should be mentioned that the mop textile cover 40, which is explained in more detail below, also has two acute-angled corner areas 40a, 40b with an interior angle β and two obtuse-angled corner areas 40c, 40d to match the shape or outline 10g of the base plate 10, i.e. its textile base area 40g is adapted to the base plate 10. An interior angle β can preferably be essentially identical to the above-mentioned interior angle α of the acute-angled corner areas 10a, 10b of the base plate 10, possibly minimally, i.e. a few degrees larger.

The base plate 10 further comprises an upper side 11 on which the previously mentioned coupling point 12 for the handle 60 is located, more precisely the relevant end 61 of the handle 60 (which is close to the ground when in use). At the coupling point 12 there is an articulated coupling mechanism 90 (see Figure 4 ). A part of the coupling mechanism 90 is a fork joint 17 on the base plate 10. This protrudes vertically upwards from the base plate 10 on the upper side 11 and forms with its two parallel "fork tines" or legs, each with a pin, spaced 55L apart in the longitudinal direction (see Figure 5 ) a first fork joint axis 96 or longitudinal axis of rotation 96. Between the legs it accommodates a joint cube 91, which for this purpose is provided in two side surfaces 91a, 91b facing the legs of the fork joint 17, each with a round bore 92 or a receiving hole 92. In these, in the coupled state (uncoupled see again Figure 5 ) a pin formed on the inside of each leg of the fork joint 17 is rotatably mounted. This allows the base plate 10 with the fork joint 17 to be rotated about the first fork joint axis 96. On two further side surfaces 91c, 91d of the joint cube 91 in the transverse direction 55Q of the base plate 10, this has a further receiving hole 92 for a further fork joint 94 on an adapter 93, which in turn has a pin on the inside of the legs. This allows the second fork joint 94 with the adapter 93 to be rotated about a second fork joint axis 97 or transverse rotation axis 97. In summary, the coupling mechanism 90 represents a two-axis joint or double joint and thus allows the stem 60 to be pivoted relative to the base plate 10 on an entire "hemispherical surface". That is, the base plate 10 is mounted on the handle 60 or at the end 61 of the handle 60 with sufficient mobility to be able to move it over the floor in any desired wiping motion for cleaning a floor.

For coupling with an end 61 of the stem 60, the adapter 93 itself has an adapter element 95 on a side facing away from the fork joint 94, which can be designed for a particular stem type. The adapter element 95 comprises Figure 1 and 5 a sleeve with a simple internal thread for solid material handles or handles 60 with a matching external thread at the end 61. These are found mainly in the American region. In Figure 4 an alternative variant of the adapter element 95' is shown, in which it has a conical fitting section 98 and a conical threaded section 99. These allow coupling with hollow stems or stems 60 that do not have an extra external thread at the end 61. Such stems are particularly common in Europe.

During use, the mop textile cover 40 is arranged on the back of the upper side 11, i.e. on a lower side 21 of the base plate 10, and is detachably fastened.

In order for the mop textile cover 40 to adhere securely to the underside 21 of the base plate 10 during use - ie, for example, during lateral wiping movements and when slightly lifting, e.g. to wipe the next step or the next room behind a threshold - the base plate 10 has a hook strip 22 as an adhesive element 22, preferably a Velcro element 22, at least in a central area ( Figure 3 ). The mop textile cover 40 is in turn attached to this hook strip 22 with a fleece strip 42 as a counter-adhesive element 42, preferably a counter-velcro element 42 ( Figure 1 ). This very simple Solution already ensures a solid hold between base plate 10 and mop textile cover 40. Alternatively, a material could be selected for the mop textile cover 40 (at least on the top side 41 or inside 41) which adheres to the hook strip 22. The same material can be used for the underside 51 of the mop textile cover 40, i.e. the side of the mop textile cover 40 which comes into contact with the floor to be cleaned during use, provided it is suitable as a cleaning material for the floor.

For an even more solid, better grip, the mop textile cover includes 40 in Figure 1 In addition, on a first acute-angled corner area 40a of the textile base area 40g on an upper side 41 or inner side 41, there is an insertion pocket 43. This consists of an essentially triangular material section which is sewn onto the mop textile cover 40 in the first acute-angled corner area 40a to form a "pocket" so that the first, acute-angled corner area 10a of the base plate 10 can be inserted or threaded into it. This then ensures that the mop textile cover 40 is held particularly securely in position on the base plate 10 in this corner area 10a as well.

In addition, the mop textile cover 40 comprises a first quick-release element 45 on a second acute-angled corner area 40b opposite the first acute-angled corner area 40a of the textile base area 40g, here in the form of an elongated, flexible piece of material 45, in particular in the form of a textile Velcro tab 45l, more precisely a fleece strip 45l, which is fixedly attached to a further hook strip 16 as a counter-coupling element 16 of the base plate 10 on the upper side 11 of the base plate 10 (see Figure 1 ). As shown by Figure 2 As can be seen, the Velcro tab 45l, in the case shown the fleece strip 45l, can be attached to the hook strip 16 of the base plate 10 very quickly, easily and simply in fractions of a second and can be removed again just as quickly.

As an alternative variant to such a flap 45l, in particular Velcro flap 45l, the mop textile cover 40 can also simply have a flexible, elongated piece of material 45 in the form of a band, a cord, a string or the like as the first quick-release element 45 and can be fastened with it, as in Figure 2C and 2D shown.

To match this, the base plate 10 can be used as an anchoring means 18k, 18s on the base plate 10 a cleat 18k (see Figure 2C ) In order to connect the "horns" of the cleat 18k pointing away from each other, with a little practice and the right technique, In other words, within a few seconds the flexible, elongated piece of material 45 can be effectively wound or knotted, for example in the form of a horizontal "figure eight" in the manner of a "Dopino" knot (ie a started slip knot with a half hitch at the end, the other way around as with a normal head hitch).

Particularly preferably, however, the anchoring means 18k, 18s can be designed in the form of two spaced-apart fastening pins 18s, as in Figure 2D shown. These can preferably be designed to be slip-resistant or provided with a slip-resistant coating so that the flexible, elongated piece of material 45 does not slip and thus becomes loose when it is wrapped around it. For example, they can have a rubber coating or alternatively a particularly rough coating. It is also conceivable that they have a type of profile or thread which prevents the piece of material 45 from slipping. Alternatively, they can also have a type of "head" which prevents the piece of material 45 from slipping (indicated in Figure 2D ).

Such a flexible, elongated piece of material 45 can also form a loop 45s with the mop textile cover 40, for example as shown here in Figure 2B shown, each of which is sewn onto the contour edges 46 of the mop textile cover 40 that enclose the acute angle. The loop 45s mentioned can specifically consist of an elastic band or elastic band, for example, which enables the mop textile cover 40 to be quickly attached to a corner, e.g. the corner area 10b of the base plate 10.

Finally, the mop textile cover 40 in Figure 1 In order to further improve the hold on the base plate 10, an optional insert band 44 is provided. This runs between a short diagonal 56 and the insert pocket 43 essentially parallel to the short diagonal 56 on the upper side 41 of the mop textile cover 40 (e.g. in the position shown here closer to the short diagonal 56 slightly off-center from the center of the mop textile cover 40) and connects the two relevant outline edges 46 in the transverse direction 55Q in a band-like manner, forming a loop, in order in turn to accommodate the associated acute-angled corner region 10a of the base plate 10. This insert band 44 is designed to be inelastic so that the mop textile cover 40 lies or remains as close as possible to the base plate 10.

In the two fastening surfaces 15a, 15b already mentioned above, two through-holes 25 are formed as parts of second quick-release elements 25 through the base plate 10 from the top side 11 to the bottom side 21.

As shown in the exploded view according to Figure 5 As can be seen from a further embodiment of a cleaning set 1 according to the invention with a cleaning attachment 70, the cleaning attachment 70, here for example a brush plate 70, can be attached to the bottom of the base plate 10 in a very simple manner, e.g. by screwing, as a further variant, for example for cleaning a rougher floor covering. In this case, the brush plate 70 replaces the mop textile cover 40. Such a brush plate 70 is also suitable, for example, for particularly stubborn dirt. The brush plate 70 is adapted in shape to the base plate 10 and accordingly has a diamond-shaped base area 70g and an upper side 71 with two internally threaded holes 72 and an underside 73 with bristles 74. The above-mentioned through holes 25 are therefore used to fasten the brush plate 70 to the base plate 10 using two suitable screw elements 80, here wing screws 80, i.e. threaded rods with wing nuts, so to speak. However, the invention is not limited to such wing screws alone. Other comparable screw means or cylindrical clamping or spreading means are also possible, which can be clamped or spread within the through holes.

The wing screws 80 are guided through the through holes 25 for fastening from above, i.e. an upper side 11 of the base plate 10, and are screwed into the internally threaded holes 72 on the upper side 71 of the brush plate 70. The base plate 10 and the handle 60 thus enable convenient guidance and cleaning of the floor with the brush plate 70.

In addition to the brush plate 70 shown as an example as a possible cleaning attachment 70, a selection of other (not shown) cleaning attachments, such as a sponge element or a pad plate, can also be attached to the base plate 10 in the same or at least a similar manner.

According to a further embodiment of a cleaning set 1 according to the invention, alternatively - as in Figure 6 shown - a holding plate 75 with a holding element 79 on a bottom side 78 of the holding plate 75 for detachably coupling the mop textile cover 40 to the base plate 10 in the same or at least a similar way. The holding plate 75, which has a diamond-shaped base surface 75g adapted to the diamond-shaped outline 10g of the base plate 10, represents an alternative solution, to attach the mop textile cover 40 indirectly to the base plate 10, as in Figure 6 shown.

The holding plate 75 with holding element 79, preferably adhesive element 79, in particular Velcro element 79, is a plate which, in comparison with the Figure 5 shown brush plate 70 except for the bristles 74 on the underside 73 of the brush plate 70.

In contrast to the brush plate 70, the holding plate 75 - instead of bristles 74 for cleaning the floor - here has a holding element 79 for detachably coupling the mop textile cover 40 essentially on the entire underside 78, so that the mop textile cover 40 can be attached to the holding element 79 very quickly for cleaning a floor and can also be detached again just as quickly. In this respect, this could also be referred to as an adhesive plate 75. The holding element 79 here comprises, for example, an adhesive coating or adhesive coating in the form of a large number of small hooks to which the material of the mop textile cover 40 adheres excellently if the right material is selected. These can be integrated into the holding plate 75 during production, preferably by means of injection molding. This has the advantage that the base plate 10 could then basically do without a counter-coupling element for the first quick-release element and could only function as a "base plate". Furthermore, when using such a holding plate 75, a mop textile cover 40 without insertion pockets or without a first quick-release fastener element can be provided.

In order to further improve the hold of the mop textile cover 40 on the hooks of the holding element 79, an upper side 41 of the mop textile cover 40, i.e. a side of the textile cover 40 facing the adhesive element 79 in the coupled state, can be provided with at least one, preferably several fleece strips, in particular with a fleece surface over the entire surface as a counter-adhesive element.

For cleaning with the holding plate 75, this is screwed onto the base plate 10. Here, too, the wing screws 80 for fastening are guided from above, i.e. an upper side 11 of the base plate 10, through the through holes 25 and screwed into suitable internal thread holes 77 on an upper side 76 of the holding plate 75. A mop textile cover 40 is then attached to the underside 78 of the holding plate 75. This is then used to clean until it is dirty to a certain degree or a certain floor area has been cleaned. After this, in a very short time With one hand, the mop textile cover 40 can simply be pulled off the adhesive element 79 of the holding plate 75 and a new, fresh mop textile cover 40 can be pulled on or attached.

In the Figures 7 and 8 a further embodiment of a cleaning set 1 according to the invention with a handle 12' on the upper side 11 of the base plate 10 is shown.

The base plate 10 again has a diamond-shaped outline 10g with two acute-angled corner regions 10a, 10b located opposite each other at the ends of a longer first diagonal of the diamond, as well as two obtuse-angled corner regions 10c, 10d located opposite each other at the ends of a shorter diagonal running perpendicular to the first diagonal ( Figure 8 ). The base plate 10 is - as in the other embodiments - mirror-symmetrical with respect to both diagonals.

The interior angle of the acute-angled corner regions 10a, 10b is preferably at most 70°, particularly preferably at most 60° and/or preferably at least 35°, particularly preferably at least 40°. Most preferably it is approximately 50°.

The interior angle of the obtuse-angled corner regions 10c, 10d is preferably at least 115°, particularly preferably at least 120° and/or preferably at most 145°, particularly preferably at most 140°. Most preferably it is approximately 130°.

Since such a cleaning set 1 with a handle 12' can also be used for cleaning by hand, it is advisable to also produce a smaller version.

The length of the first diagonal is therefore preferably at most 35 cm, particularly preferably at most 30 cm and/or preferably at least 20 cm, particularly preferably at least 25 cm. Most preferably, this length is approximately 26 cm.

Given the length of the first diagonal and the interior angles in the corner areas, the length of the second diagonal is already clearly defined.

However, the dimensions can be such that the length of the second diagonal is preferably at most 15.5 cm, particularly preferably at most 15 cm and/or preferably at least 13 cm, particularly preferably at least 14 cm. Most preferably, this length is approximately 14.5 cm.

The handle 12` is arranged on the upper side 11 of the base plate 10 such that a longitudinal direction of the handle 12' runs along the first diagonal from one of the acute-angled corner regions 10a, 10b to the other.

The handle 12` is constructed in a kind of lattice design with two struts 12a`, 12b` running one above the other in the longitudinal direction of the handle 12', essentially in an arc shape from the first acute-angled corner region 10a to the second acute-angled corner region 10b of the base plate 10, namely an upper arched strut 12a` (or upper strut 12a`) and a handle strut 12b` (or lower strut 12b') running underneath. At the apex, the handle strut 12b` is connected to the arched strut 12a` above it via a cross strut 12c' (running essentially vertically relative to the surface of the base plate 10). To the right and left of the cross brace 12c`, between the arch brace 12a` and the handle brace 12b', there are two cavities 12h` in the handle 12'.

A coupling eyelet 12l' runs through the cross brace 12c' itself between the handle brace 12b' and the bow brace 12a', which can be used for coupling with a suitable adapter on a handle. The coupling eyelet 12l' is formed here by a simple coupling hole or a coupling bore 12l', the axis of which runs transversely to the longitudinal extension of the handle 12' and parallel to the second, shorter diagonal of the base plate 10. An adapter, such as that shown in the EN 10 2019 113 870 A1 described above, or that referred to above in connection with Figure 5 shown adapter element 95 can be coupled directly. The axis of the coupling eyelet 12l' then forms a first pivot axis D1, about which the handle can be pivoted relative to the base plate 10. However, as already described, it is also possible here, for example, to use a joint mechanism in an adapter that allows pivoting by several degrees of freedom

Thus, the handle 12' itself already forms a suitable coupling point 12' for a shaft.

The handle bar 12b` is designed and arranged in such a way that a sufficiently large grip eyelet 12o' remains between the top side 11 of the base plate 10 and the handle bar 12b', into which a user can easily reach with four fingers of his hand. In addition, the handle bar 12b` is shaped in such a way that it has several (here specifically four) grip recesses 12g' in order to comfortably place the four fingers on the handle bar 12b`.

The arched strut 12a' running above the handle strut 12b' is also shaped in such a way that it allows the handle 12' to be gripped as ergonomically as possible. In the present case, the arched strut 12a' has a slightly curved elongated upper section in the uppermost area and two steeper end sections running at an obtuse angle from it to the top of the base plate 10. These end sections are also only slightly curved.

To better stabilize the handle 12' on the base plate 10 and to stabilize the sharp corners of the base plate 10, a reinforcing bar 10s' runs in the end areas of the longer, first diagonal on the top side 11 of the base plate 10 between the handle strut 12b' and the arched strut 12a' and beyond these into the sharp corner. This reinforcing bar 10s' is shaped in such a way that it becomes thinner and lower towards the tip of the base plate 10.

The entire handle 12' with all struts 12a', 12b', 12c' and the reinforcing bars 10s' is designed in such a way that it is particularly ergonomically shaped and enables working as gently and fatigue-free as possible. In addition, on the one hand, due to the lattice construction, it is relatively light and requires only relatively little material, and on the other hand, it is arranged extremely stably on the base plate 10. It is preferably manufactured in one piece with the base plate 10 (particularly preferably using an injection molding process).

In Figure 8 Another possible variant is schematically indicated, which allows a pivotable coupling of a handle with the base plate on a handle 12' around two pivot axes D1, D2. The first pivot axis D2 is defined by the axis of the coupling eyelet 12l'. The handle 12' would then be additionally divided into three sections, for example, at the dashed dividing lines T. In this case, the handle 12' would then be, unlike in Figure 8 shown, preferably not manufactured in a lattice construction, but the area between the handle strut 12b` and the arched strut 12a' could be filled over its entire surface, ie the handle 12' would then have, for example, a single wide arch (preferably with the grip recesses 12g' on the underside facing the base plate 10). Alternatively, the handle strut 12b` and the arched strut 12a' could have further cross struts to the right and left of the dividing lines. In the area of these dividing lines T, the middle section of the handle 12' arranged between the dividing lines T can then be pivoted about a second pivot axis D2 with the two outer sections of the handle, which are firmly connected to the top 11 of the base plate 10, thus a The coupling eye 12l' coupled handle is here pivotably coupled to the base plate 10 about two mutually perpendicular pivot axes D1, D2.

At the dividing lines T, there may also be cooperating locking means, arresting means or the like on the middle section and on the outer sections of the handle 12' in order to hold the middle section of the handle 12' in a basic position in which the pivot axis D1 runs through the coupling eyelet 12l' parallel to the upper side 11 of the base plate 10 (i.e. in the position shown in Figure 8 shown in the position of the coupling eyelet 12l'), whereby with a little additional force the middle part can then be pivoted out of this basic position.

On the underside 21 of the base plate 10 there is again an adhesive element 22 in the form of a Velcro element 22. However, this extends over the entire surface of the underside 21, apart from a thin peripheral edge area. In principle, the adhesive element 22 could also extend completely over the underside 21. Here too, the adhesive element 22 or Velcro element 22 can be designed in the form of a type of hook surface or the like with a large number of (small) hooks, spikes, etc., to which the material of the mop textile cover 40 adheres excellently if the right material is selected. These hooks, spikes, etc. can particularly preferably also be integrated into the underside 21 of the base plate 10 or formed on it when the base plate 10 is manufactured, in particular by injection molding.

On the back side of the top side 11, i.e. on a bottom side 21 of the base plate 10, the (in the Figures 7 and 8 The mop textile cover 40 (shown separately) is arranged and detachably fastened.

This mop textile cover 40 is again designed to match the shape or outline 10g of the base plate 10, i.e. its textile base area is adapted to the base plate 10.

Here, the upper side 41 of the mop textile cover 40, ie the side of the textile cover 40 facing the adhesive element 22 in the coupled state, is preferably provided over its entire surface with a fleece surface or the like as a counter-adhesive element.

Particularly suitable materials for the mop textile cover 40 (for realizing a suitable adhesive upper side 41 facing the adhesive element 22 as well as an underside particularly suitable for cleaning) can be selected as described above generally or also for the other embodiments.

Although the quick and easy replacement of a dirty mop textile cover with a fresh, washed mop textile cover is considerably more important in commercial cleaning than in private use, since the mop textile cover is usually washed, wrung out and then reused several times, the invention can of course also be advantageous for private use. Particularly since frequent washing and wringing can be very tiring and stressful for the hands in the long run. Not to mention that such an approach with several fresh mop textile covers, which are only washed together in the washing machine with hot water after the floor has been cleaned, would also be more hygienic at home.

Finally, it should be pointed out once again that the devices described in detail above are merely exemplary embodiments which can be modified in a variety of ways by a person skilled in the art without departing from the scope of the invention. For example, other coupling elements for coupling the cleaning attachments to the base plate than the screw elements mentioned, such as universal closures with integrated cap lifters, as are known for closing glass bottles, in particular wine bottles, quick-release levers, etc. are also included in the scope of the invention. The cleaning set is particularly well suited for cleaning a floor. In principle, however, it can also be used for cleaning a wall, table or ceiling surface. In particular, it is also suitable for wiping, applying a cleaning fluid and disinfecting a wall, table or ceiling surface. Furthermore, the use of the indefinite articles "a" or "an" does not exclude the fact that the features in question can also be present multiple times. Likewise, the term "element" does not exclude the fact that the component in question consists of several interacting subcomponents, which can also be spatially distributed if necessary.
