Description

The invention relates to a floor cleaning device for manual operation and for cleaning dry, wet or damp floors with a handle, which is connected at one end of its longitudinal extension to a rail-like contact element holder, so that the contact element holder in its longitudinal extension into a first and a second contact element side is subdivided, the contact element holder having a groove on the side of its longitudinal extension facing away from the handle, a contact element being held in the groove.

It is generally known that floors in houses and plants, for example in households, commercial, industrial plants, public buildings or hospitals, require regular cleaning and maintenance. The cleaning is done dry, for example with a broom, or damp or wet. For example, wide mopping devices, mops or scrubbers are used for this.

Wide mopping devices are used for dry or damp cleaning of floors. Wide mopping devices are less suitable for cleaning wet floors. As a wiping element, they often have a type of wiping plate that is articulated to an operating rod. This means that the wiper plate can be moved flat over the floor to be cleaned. The wiper plate has a comparatively small thickness, while one of the two largest side surfaces serves to clean the floor, while the other side surface is connected to the rod. With the wide mop device, only the floor is wiped, because this device is not designed for the use of force by the operator on the handle. To increase the cleaning performance, the wiper plate is often wrapped in a cleaning cloth or the cleaning cloth has pockets into which the wiper plate is inserted. For the dry cleaning of dust or lint, cleaning papers or paper-like, particularly light cleaning wipes are also known, which are clamped on the wiper plate and have a weight per unit area of about 10 to 90 grams / m ² . By wiping with the large side surface, it is possible to clean a comparatively large area of the floor in a relatively short time, and the dirt-binding capacity, i.e. the possibility of absorbing a certain amount of dirt, in particular dust and lint, is also high due to the large side surface .

In contrast, a scrubber is a floor scrubber with a wide brush that has harder bristles on a stick. With the scrubber it is possible to clean floors that have a smooth and hard surface, both dry and damp, as well as wet. The brush can also be wrapped with a cleaning rag to clean the floor damp or wet. Alternatively, the damp floor can be dried with a dry cloth. An essential difference from the scrubber to the wide mop is that the hard bristles make it possible to scrub the floor with force and not just to wipe it. For this purpose, the rod is usually firmly connected to the brush.

Another floor cleaning device is a puller that is used to remove liquids on a smooth floor as efficiently and quickly as possible.

From the EP 1 529 480 A1 Another device for floor care has become known that can not be assigned to the wide mop devices. There, namely, a device for floor care is presented, which has a handle and a dryer part with a wiper blade, which works the floor with a narrow side, which distinguishes it from the wide mop devices. A dry, damp or wet cloth can be attached to a dryer part be attached. An edge part of the cloth is clamped between the holders and the dryer part, so that the cloth is fixed. The brackets are neither rigidly connected to the dryer part nor to the handle. Therefore, in this patent, the brackets are further developed to have a clamping part at one end which is fitted over the dryer part and a locking head at the other end which is suitable for being locked to the dryer part by means of an opening, recess or notch be such that the interlocked parts form a dovetail connection. In this way, the brackets are connected to the device and cannot be lost.

A disadvantage of this prior art is that changing the cloth in the floor care device is comparatively time-consuming. After all, the brackets are intended to fix the cloth firmly on the dryer part. For this purpose, the holders have to be positioned at a position provided for them above the dryer part, then the cloth has to be put in between and finally the holder has to be put on the dryer part with the cloth inserted in between. Since the connection is made via a force clamp, which holds better the harder the holder is pressed onto the dryer part, the operator tries to press the holder onto the dryer part with sufficient force until the best possible clamping effect is achieved. When changing the cloth, the holder must be removed from the dryer part accordingly. It can happen that the clamping effect of the force clamping is so high that the holder can only be removed with a correspondingly high counterforce.

Based on this prior art, it is an object of the invention to provide a floor cleaning device and a floor cleaning system for dry, moist and wet cleaning of floors, which is particularly one enables simple and quick cloth change and at the same time has the simplest possible structure.

The object is achieved by a floor cleaning device of the type mentioned at the outset. This is characterized in that at least one cloth impression fastening device is arranged on each side of the contact element.

A cloth printing fastening device is an independent component in which a cleaning cloth can be clamped. For this purpose, the cloth impression fastening device has a flat, usually flat area, which is made of flexible material, for example plastic. In this area there are cuts or recesses which are arranged such that a number of tongues are formed in this area. Frequently, the area can be seen in plan view as a circle, square, rectangle or ellipse, the cuts being arranged in such a way that the tongues have approximately the shape of circular sections or circular segments. In this way, a cleaning cloth can be pressed easily and easily into the middle approximately in the area, the flexible tongues bending in such a way that the cleaning cloth is jammed or hooked between the tongues. With a floor cleaning device that has such cloth pressure fastening devices, changing the cleaning cloth is particularly quick and easy. It has surprisingly been found that even comparatively thick and heavy qualities of cleaning cloths can be fastened in such cloth printing fastening devices. This is because only a correspondingly strong pull on the cleaning cloth is necessary in order to release the jamming or hooking of the cleaning cloth in the cloth press fastening device. Finally, several of the otherwise necessary steps when changing the cloth, such as removing a cloth clip from the contact element holder, are omitted Position the cleaning cloth between the cloth clip and contact element holder and then attach the cloth clip to fix the cleaning cloth between the cloth clip and contact element holder.

In addition, the construction of the floor cleaning device according to the invention is simplified. Namely, only one component, namely the cloth impression fastening device, is necessary to fix a cleaning cloth. The comparatively complex jamming of the cleaning cloth between two different components is eliminated. It is also no longer necessary to provide other structural means, for example axes of rotation, belts or lines, in order to correctly position the two components relative to one another, or to secure the clamp against loss. A further simplification of the structural design is that the cloth impression fastening device is designed, for example, in one piece.

An advantageous development of the floor cleaning device is characterized in that two or three cloth pressure fastening devices are arranged on each half of the contact element holder.

In this way, the cleaning cloth can be attached particularly precisely to the floor cleaning device. In addition, the holding force with which a cleaning cloth is held on the floor cleaning device is increased with a higher number of cloth impression fastening devices. Another advantage of several cloth impression fastening devices on each half is that the arrangement of the cloth impression fastening devices is carried out in accordance with the distribution of forces that are introduced into the floor cleaning device by the cleaning cloth. For example, cloth printing fastening devices can be arranged along an imaginary line, or in another pattern, in particular offset to the imaginary line. Accordingly, the positions of the cloth printing fastening devices can be selected so that the forces acting on the cleaning cloth are the same on each cloth printing fastening device. Alternatively, a cloth pressure fastening device is to be dimensioned according to the forces acting on its position. This is done, for example, by the tongues for clamping being formed or manufactured from a correspondingly stronger or weaker material, the shape of the tongues whose flexibility is increased or decreased, or by the tongues being made from another material which causes higher or lower clamping forces, depending on what is needed at the point in question.

In addition, in an alternative embodiment of the floor cleaning device, it is provided that the at least one cloth impression fastening device is arranged on at least one mounting rail and can be fixed at a desired location on at least one mounting rail, and that the at least one mounting rail is connected to the contact element holder.

In this way, a cloth impression fastening device is connected to the contact element holder with the interposition of a mounting rail. A cloth printing fastening device can accordingly be plugged onto a desired location on the rail or displaceable along the rail. The fixation of the cloth printing fastening devices at the desired location on the rail is implemented in a simple manner, for example by means of a clamping device, a latching device or a plug-in device. The position of a cloth printing fastening device on the mounting rail can thus be advantageously changed, that is to say it can also be adapted to the width of the cleaning cloth.

A further advantageous variant of the floor cleaning device is characterized in that the contact element holder has two leg elements which are connected to one another with a connecting piece, that the cloth impression fastening device has a cloth impression plate, that an imaginary plane is determined by the cloth impression plate, and that the imaginary plane is perpendicular to the is to the handle-facing side of the connecting piece and / or is arranged approximately parallel to the longitudinal extension to a leg element.

In such a configuration of the floor cleaning device, the cloth printing plate is arranged practically vertically on the connecting piece. As a result, the cleaning cloth can be inserted particularly easily into the cloth printing plate from each of the two sides, as a result of which particularly simple and flexible handling and use of the floor cleaning device is achieved. If the cloth printing plate is also arranged parallel to the longitudinal extension to a leg element, the insertion or pressing of the cleaning cloth into the cloth printing plate is also simplified. The main direction of movement of the floor cleaning device is a back and forth movement, which takes place along the floor to be cleaned and occurs perpendicular to the longitudinal extent of the contact element or the contact element holder. This means that in the case mentioned above, the cleaning cloth can be inserted into the cloth printing plate in the direction of one of the main directions of movement of the floor cleaning device. The same advantage arises when the cloth impression fastening devices are arranged on one of the two leg elements. In this case too, the cloth impression plate is arranged parallel to the longitudinal extension of the leg element in question. Of course, the cleaning process is not limited to the main directions of movement. Also, for example, an otherwise usual circular movement or a so-called figure of eight as a cleaning movement can easily be carried out with the floor cleaning device.

Another advantage for the floor cleaning device is obtained if the cloth printing plate is detachably connected to a cloth printing plate holder of the cloth printing fastening device.

The cloth printing plate is a mechanically particularly heavily loaded component. For example, one of the flexible tongues can be damaged. Because the cloth printing plate can be detached from its cloth printing plate holder, it is particularly easy to replace. It is also possible to replace a cloth printing plate with another one, which for example has a greater thickness, that is to say has a stronger design, in order, for example, to jam thicker, heavier cleaning wipes. The interchangeability is ensured, for example, by the fact that the cloth printing plate is circular, the diameter of the cloth printing plate being adapted to a recess of the cloth printing plate holder such that it can be inserted into the recess, for example up to a collar or a web in the recess. The fixation of the cloth printing plate is then made possible, for example, by a screw which is screwed into a corresponding thread in the recess and in this way the cloth printing plate is braced against the collar or the web. However, other holders or fixings for a cloth printing plate in a cloth printing plate holder, for example clamping or tensioning devices, are also conceivable without further notice. The shape of the cloth printing plate holder can also be configured flexibly. The shape can, for example, be cuboid, cube-shaped, circular disk-shaped or ring-shaped, the side of the cloth impression plate holder facing the mounting rail or the contact element holder having corresponding connecting elements to the mounting rail or to the contact element holder.

A further embodiment of the floor cleaning device provides that at least one of the Cloth printing fastening devices are arranged on a leg element such that the leg element has a first recess assigned to each cloth printing fastening device and the contact element has a second recess assigned to each cloth printing fastening device, and that the positions and dimensions of the first and second recesses are matched to the assigned cloth printing plate such that a A pressed-in cleaning cloth part can be inserted into the first and second recess.

In such a floor cleaning device, the construction and operability are further simplified. The particularly easy insertion of the cleaning cloth perpendicular to the main operating direction of the floor cleaning device is achieved by arranging the cloth impression fastening devices on a leg element. The recesses, which are arranged directly behind the cloth printing plate, as seen in the insertion direction of the cleaning cloth, create space for the cloth part of the cleaning cloth pressed into the cloth printing plate. Thus, the cloth impression fastening devices can be designed to save space and their construction is simplified. The second recess in the contact element can also be designed, for example, as a through hole through the entire thickness of the contact element. Then there are openings in the contact element on both sides of the second recess, the first recesses being arranged on both leg elements such that openings and first recesses are located one above the other. In the case of cloth pressure fastening devices arranged at these points, a cleaning cloth can in turn advantageously be pressed in on the cloth pressure fastening devices on the first leg element and / or optionally on the second leg element.

Furthermore, it is advantageous if the floor cleaning device is designed such that the cloth printing fastening device or the cloth printing plate is held in the first recess. This ensures that the first recess on or in the leg element functions functionally as a cloth impression plate holder, so that the construction of the floor cleaning device is further simplified in this way. In such an embodiment, a holding device or a connecting device is provided either on the cloth printing plate, on the cloth printing plate holder or on the leg element, with which the leg element can be connected either to the cloth printing plate or to the cloth printing plate holder.

The advantage of a floor cleaning device in which the cloth printing fastening devices are arranged exclusively on the connecting piece or in which the cloth printing fastening devices are arranged exclusively on one of the leg elements is that a particularly simple change of the cleaning cloth can be carried out here.

In a floor cleaning device according to the invention, the contact element is made of rubber, foam rubber, plastic or other materials with rubber-like or elastic properties. On the one hand, these materials are so flexible that they ensure contact from the contact element to the floor during the cleaning process, and on the other hand they are stable enough to absorb the forces acting on the contact element. The contact element, in particular the areas facing the floor (hereinafter also referred to as contact body or contact parts), is advantageously designed in a segment-like manner, for example by one or more interruptions or cuts substantially perpendicular to the longitudinal extension of the contact element or parallel to the main directions of movement of the floor cleaning device. The juxtaposition of at least two segments thus achieved makes a better one Floor contact of the contact element or the floor cleaning device achieved on uneven surfaces.

In the floor cleaning device, it is also provided that the shapes and dimensions of the leg elements and the connecting piece are matched to the shape of the contact element in such a way that the contact element is held in a form-fitting manner in the contact element holder. In addition, cover elements can also be provided, which are attached to the end faces of the contact element holder. This reliably prevents a contact element that is held in a positive or non-positive / positive manner from sliding out of its contact element holder.

If the contact element is held in a form-fitting manner in the contact element holder, it is advantageous that the positioning of the contact element is predetermined in terms of construction. In addition, a large number of positive connection options are known and provided, for example a contact element holder whose cross section is dovetail-shaped or U-shaped with bent free ends of the leg elements.

As an alternative to positive locking, it is also within the inventive concept that the dimensions of the contact element are matched to the dimensions of the contact element holder in such a way that the contact element is held in the contact element holder in a force-locking manner. In this case, too, a variety of design options are available.

A further development of the floor cleaning device is achieved if part of a fixing element is connected to at least one of the leg elements and another part of the fixing element in a corresponding third Recess is positioned in the side facing the leg element or the sides of the contact element facing the leg elements.

In this way, the contact element is connected by the fixing element to the leg element or the leg elements and thus in the contact element holder. This is, for example, an additional security measure to connect a contact element to the contact element holder, that is, an additional security measure for a non-positive and / or positive connection of the contact element to its contact element holder.

It is also within the concept of the invention if, in the case of a floor cleaning device, the handle is connected to the contact element holder with the interposition of a swivel joint. In this way, the contact element holder is articulated to the handle. The swivel joint thus increases flexibility when using the floor cleaning device. The cleaning direction for a cleaning movement can be changed particularly easily by the operator of the floor cleaning device without the operator having to change his position. In addition, the ease of use for cleaning work is increased.

In the event that an axis of rotation of the swivel joint is perpendicular to the longitudinal extension of the contact element holder and perpendicular to the longitudinal extension of the handle, the overall stability of the floor cleaning device increases. In addition, it is particularly easy for an operator of the floor cleaning device to transmit a force which he has applied to the handle, to the contact element holder and thus to the contact element. This is because there is no risk that the swivel joint will take up a rotary or tilting movement, and this prevents the force from being transmitted to the contact element.

In addition, the object of the invention is achieved by a floor cleaning system with a floor cleaning device mentioned above and a cleaning cloth, which is pressed into the cloth printing fastening devices with a cleaning cloth edge, that a partial area of the cleaning cloth held in the cloth printing fastening devices is arranged between the contact element and the surface to be cleaned is that the surface section of the cleaning cloth in contact with the contact element indicates the effective cleaning area of the cleaning cloth, and that the material of the contact element at least on the surface section of the cleaning cloth in contact has such a high coefficient of friction that the surface section in contact during a cleaning process remains on the contact element.

This ensures that the cleaning cloth is only fixed with the contact element. A fixation of the cleaning cloth by other components, for example the cloth pressure fastening devices, is not necessary for the cleaning process. In this case, the cloth pressure fastening devices have the primary task of connecting the cleaning cloth to the floor cleaning device as a whole, so that it is particularly easy to pick up the floor cleaning device together with the cleaning cloth from the floor and to put it back on at a different location on the floor, for example, there continue the cleaning process. In addition, it is possible to change the surface section on the cleaning cloth that is currently in contact with the contact element, for example because the previous surface section is contaminated by the cleaning process, the cleaning cloth remaining on the floor cleaning device. Due to the possibility of changing the surface section - even several times - the capacity of the cleaning cloth to bind dirt particles or moisture is more advantageous Way better used than would be possible with cleaning with only one surface section of the cleaning cloth. In addition, the tensile load on the cloth impression fastening devices is reduced.

Further advantageous design options can be found in the further dependent claims.

The invention also relates to all combinations of preferred configurations, insofar as these are not mutually exclusive. The information "about" or "approx." in connection with a number means that at least 10% higher or lower values or 5% higher or lower values and in any case 1% higher or lower values are included.

The invention, further embodiments and further advantages are to be described in more detail on the basis of the exemplary embodiments illustrated in the drawings. The examples serve to explain the invention, but the invention is not intended to be limited to the specifically described embodiments.

Fig. 1 shows a first side view of a first floor cleaning device 10 with a handle 12, which has a fastening element 14 at one end of its longitudinal extent. With the fastening element 14, the handle 12 is connected to a first contact element holder 16. A first contact element 18 is non-positively clamped in a first groove 17 of the first contact element holder 16, which is arranged on the side of the first contact element holder 16 facing away from the handle 12. In addition, the first contact element 18 is additionally connected to the first contact element holder 16 with a first 20 and a second pin 22 as fixing elements. In this way, a connection of the contact element with the contact element holder - additional for clamping these two components - is created. For example, it is also conceivable that the contact element in the contact element holder has no clamping effect at all, but is, for example, only held loosely in it. In this case, the pins connect or fix the contact element at a specific position.

The first contact element holder 16 is approximately rail-shaped. The fastening element 14 of the handle 12 is attached centrally to a longitudinal extent of the first contact element holder 16 and thus divides the first contact element holder 16 into a left and a right half, as seen in this first side view. On the side of the first contact element holder 16 facing the handle 12, a first 24 and a second cloth impression fastening device 26 are firmly connected to the first contact element holder 16 on the left half. Each cloth printing fastening device 24, 26 has a first cloth printing plate holder 30 in which a cloth printing plate 28 is held. In the example shown, they are Cloth printing plate and the cloth printing plate holder different components that are firmly connected to each other by a corresponding connecting device. However, the two functions can also be made in one piece, so that the cloth printing fastening device is in one piece and at the same time has the functions of the cloth printing plate and the cloth printing plate holder. However, if the cloth printing plate holder has both components mentioned, the connecting device of the two components is often designed in such a way that the cloth printing plate can be replaced.

Fig. 2 shows the first floor cleaning device 10 in a second side view, which is the view of an end face of the first contact element holder 16 of the first contact element 18. The second view is rotated by 90 ° compared to the first side view. The individual components of the first floor cleaning device 10 are therefore also provided with the same reference numerals as in FIG Fig. 1 . In addition, in the Fig. 2 a cleaning cloth 32 is shown, which is inserted with a cloth edge area 34 in the cloth printing plate 28 of the second cloth printing fastening device 26 and is thus jammed or hooked. Another area of the cleaning cloth 32 lies on a floor 36. Together, the first floor cleaning device 10 and the cleaning cloth 23 form a first floor cleaning system.

The cleaning cloth 32 is held in contact with the floor 36 by the first contact element 18. For this purpose, the first contact element 18 has a first 38 and a second contact lip 39 on its side facing the floor 36. A surface area 37 of the cleaning cloth 32 between the contact lips 38, 39 is an effective cleaning area of the cleaning cloth 32. This means that this effective cleaning area is kept constantly on the floor 36 by the first contact element 18 during the cleaning process and is cleaned in this way. Another advantage is that the material of the first contact element 18 in the selected example has a higher coefficient of friction than the material of the floor 36 to be cleaned. This ensures that the cleaning cloth 32 slides over the floor 36 during the cleaning process, while the effective cleaning area on the first contact element 18 remains. In this way, the floor 36 can be cleaned with the same effective cleaning area until the cleaning cloth 32 is soiled at this point. Then it is possible for the operator in a simple manner to place the first contact element 18 on another, unpolluted area of the cleaning cloth 32 and thus to define a new, clean, effective cleaning area.

The Fig. 3 shows a second floor cleaning device 42 in a third side view, which offers a view comparable to that Fig. 1 to the first floor cleaning device 10. The second floor cleaning device 42 has a handle 44 which has a swivel joint 46 as a joint element at one end. The swivel joint 46 is connected on the one hand to the stem 44 and on the other hand to a second contact element holder 48, approximately in the middle of its longitudinal extent. In addition, the swivel joint 46 can be pivoted about an axis of rotation 47. The position of the axis of rotation 47 is selected such that pivoting in the direction of the left or the right half of the second contact element holder 48 takes place. Ideally, the dimensions of the various components of the second floor cleaning device 42 are coordinated with one another in such a way that pivoting of the handle 44 to one side or the other is made possible by 90 ° in each case, that is to say a pivoting range of 180 ° can be achieved together. When the handle is swiveled by 90 °, the handle is located parallel to the second contact element holder 48, so that in this cleaning position it is also possible to clean floor spots that are located, for example, below pieces of furniture and would otherwise be inaccessible, for example with a rigid connection between the handle handle 12 and the first contact element holder 16 according to the first cleaning device 10. Im second contact element holder 48, a second contact element 50 is clamped non-positively. For this purpose, the second contact element holder 48 has a second groove 49, which is arranged on its side facing the floor. In addition, in this view, on the side of the second contact element holder 48 facing the viewer, four third cloth impression fastening devices 52 are arranged, two of which can be seen on each side of the second contact element holder 48 in this view.

To further explain the second floor cleaning device 42, this is shown in FIG Fig. 4 is shown in a fourth side view, again with a view of an end face of the second contact element 50. The second floor cleaning device 42 is connected to a cleaning cloth 54, which together are a second floor cleaning system 40. In this exemplary embodiment of the invention, the second contact element 50 can be functionally subdivided into a base body 56 and a contact body 58, which is represented by a broken line 60. The base body 56 is essentially cuboid and is that part of the second contact element 50 which is non-positively clamped in the second contact element holder 48. While the contact body 58 has a shape and corresponding material properties which are suitable for holding the cleaning cloth 54 on the contact body 58, while the floor 36 is cleaned with the second floor cleaning system 40. In addition, in this view, that is to say viewed in the direction of the end face of its longitudinal extent, the contact body 58 has the contour of half an ellipse. The contact body 58 thus tapers in the direction of the bottom 36. This has the consequence that the surface pressure on the cleaning cloth 54, which is arranged between the bottom 36 and the contact body 58, is advantageously higher than in the case of a straight surface facing the floor 36 points. In addition, the material of the contact body 58 is selected such that its static friction coefficient is higher than that of the base 36. This has the consequence that the cleaning cloth 54 remains on the contact body 58, while the cleaning cloth 54 glides over the floor 36 during cleaning.

In this view, the second contact element holder 48 is approximately U-shaped, a first 62 and a second leg element 64 being connected to a connecting piece 66. The leg elements 62, 64 are resiliently connected to the connecting piece 66, so that the clamping force of the non-positive connection between the second contact element holder 48 and the second contact element 50 can be determined by the resilient connection. This fourth side view also shows that a third cloth impression fastening device 52 is attached to the first leg element 62. This third cloth impression fastening device 52 is pressed in the cleaning cloth 54 and is connected in this way to the second floor cleaning device 42. In the selected example, the third cloth impression fastening device 52 has a certain thickness, so that a cavity is formed which is sufficient to receive the part of the cleaning cloth 54 which is pressed into this cavity. However, it is also readily conceivable that part of a cloth printing fastening device, namely a cloth printing plate, is designed such that it is attached or fixed directly in a recess, for example a bore, in the first leg element 62. In this case, a corresponding contact element also has a recess in the region of the recess, so that a cavity is again created which can accommodate the part of a cleaning cloth which is then pressed into the cloth impression plate. It is also within the concept of the invention if the contact element has a through hole at the said point, corresponding recesses then being located on the first and second leg elements and cloth printing plates being attached there in each case. Then the cleaning cloth can advantageously be attached either to the first or second leg element.

In the example shown, the cleaning cloth 54 is a tissue cloth of a heavy quality that is usually used in a floor cleaning system, that is to say a tissue cloth of approximately 250 grams / m ² . The usual cleaning cloths used in such floor cleaning systems have a basis weight of approximately 100 to approximately 600 grams / m ² , but particularly preferably approximately 250 grams / m ² .

The Fig. 5 shows a one-piece third contact element 68 in a frontal side view of its longitudinal extent. A first base element 70, which is adapted to a connection with a contact element holder, and a first contact part 72 are shown, which are delimited by a broken line 74 for better identification of the regions. The first contact part 72 has a rectangular shape in this view. Overall, the third contact element 68 is therefore particularly robust and insensitive to mechanical loads.

The Fig. 6 shows a one-piece fourth contact element 76 in a frontal side view of its longitudinal extent. A second base element 78, which is adapted to a connection with a contact element holder, and a second contact part 80 are shown, which are again delimited by the broken line 74 for better identification of the regions. The second contact part 80 has a trapezoidal shape in this view, the tapering part of the trapezoid being arranged at the bottom in this view. Overall, the fourth contact element 76 is thus both robust and insensitive to mechanical loads and also has an increased surface pressure on a floor to be cleaned compared to the third contact element 68.

The Fig. 7 shows a one-piece fifth contact element 82 in a front side view of its longitudinal extent. There are a third Base element 84, which is adapted to a connection with a contact element holder, and a third contact part 86 are shown, which are again delimited by the broken line 74 for better identification of the areas. The second contact part 80 has a triangular shape in this view, with a tip of the triangle pointing towards the floor for cleaning, that is to say again pointing downward in this view. Overall, the fifth contact element 82 is optimized in particular for a particularly high surface pressure on a floor to be cleaned. The contact part is particularly advantageously designed in the form of a double lip or dovetail-shaped.

The Fig. 8 shows a plan view of a third contact element holder 90 of a floor cleaning device with a view of the side facing a handle. A first connection point 92 for a handle handle is arranged approximately centrally on the side of the third contact element holder 90 to be seen. Such a handle is connected to the third contact element holder 90, for example, by screwing, gluing or welding. Parallel to its longitudinal extent, a first mounting rail 94 is arranged on the left side in this view and a second mounting rail 96 on the right side of the third contact element holder 90 and is connected to the latter. The support rails 94, 96 are designed and intended to carry fourth cloth impression fastening devices 98. In the example shown, a fourth cloth impression fastening device 98 is clamped on the left and on the right side of the third contact element holder 90 on the respective mounting rail. However, the connection between a mounting rail 94, 96 and a fourth cloth impression fastening device 98 can also be made by screwing or by locking or by a similar connection technique. In this way, the fourth cloth impression fastening device 98 can be moved back and forth on its mounting rail 94 or 96 and can be fixed at a desired location. In this way Different cleaning wipes of, for example, different wipe widths can be attached to the third contact element holder 90 in a particularly simple manner.

The Figures 9a to 9d show an exemplary selection of sketches of possible design variants of cloth printing plates, short printing plates, for cloth printing fastening devices. In the case of a first impression plate 100, a flexible region which is suitable for pressing in a cleaning cloth is designed in a circular manner. Apart from the fact that a flexible material is selected for the first impression plate 100, a total of eight tongue-like circle segments 104 are produced by four suitable cuts 102. The eight circle segments 104 thus form a circular area, in which the cloth can be easily pressed in. The tips of the tongues of the circular segments 104 namely bend slightly spring-like, so that the restoring forces and the hooking of the cleaning cloth between the tongues cause the cleaning cloth to become jammed or caught on the tongues. The Fig. 9b shows a second indentation plate 106 with a flexible area which is designed elliptical. In this exemplary embodiment there are also cuts 102, namely exactly two cuts 102, which divide the elliptical area into four ellipse segments, so that flexible tongues for clamping a cleaning cloth are also produced in this embodiment of the second impression plate 106. The Figure 9c shows a third indentation plate 108, which has a comparable basic shape to the second indentation plate 106, namely rectangular in this view, and also an elliptical flexible region. In this exemplary embodiment, however, the number of cuts 102 is selected with three cuts 102 such that a total of six ellipse segments are present. Finally, in the Fig. 9d Another embodiment shown, in which two flexible circular areas 112 are shown on a fourth indentation plate 110, each having six circle segments. The above examples are intended to show that there are a multitude of possibilities in the design of impression plates for different cloth impression fastening devices, all of them can attach any kind of cleaning cloth. For this purpose, the circular, elliptical, square, rectangular or otherwise shaped flexible regions usually have a diameter of 2 cm to 10 cm or are located with their contours within a corresponding imaginary diameter. Ideally, however, this diameter or the imaginary diameter is between 3 cm and 6 cm.
