Description

Field of Invention

The invention relates to manual cleaning devices, including a handle with a handle, a cleaning nozzle and a mop cover with a removable textile element that is attached to the handle.

State of the art

From the prior art recognized several different options for manual devices for cleaning. The latter include a handle that the operator holds, and a cleaning nozzle, typically movable and attached to the handle, and are in the form of a cleaning device, which, for example, is a brush device, a wiping device, or a device on which a cleaning device is attached, such such as a mop cover.

In particular, prior art mops are made up of three basic elements. The first is the handle, the second is the mop holder, which is movably fixed to the handle, and the third is the mop cover, which is attached to the mop holder. There are various methods for attaching a mop cover to a mop holder. The squeegee cover is attached using a Velcro joint or other detachable connection to the rigid plate squeegee holder. Alternative technical solutions are also recognized from the prior art, according to which the mop holder is inserted into the nests of the mop cover. For this purpose, plate-shaped squeegee holders with folding flaps are used, which, if necessary, cleaning or changing the cover for the squeegee moves from the extended position with folding flaps that engage with each other, into the second position in which the folding flaps are inserted one into the other. In this position, the mop cover is either rinsed when the cover hangs from the mop holder, or is squeezed in the press, or the cover is completely removed from the mop holder. The squeegee holders, which are typically telescopic, therefore slide into each other along their axis in the longitudinal direction, as is known from EP 0 757 903 B1, or rotate in a direction perpendicular to the longitudinal extension of the squeegee holder, as described, for example, in the patent EP 0 663 178 B1.

These types of mop-type cleaning devices make it easy and convenient to replace the mop cover, while the mop holder itself is firmly connected to the mop holder with a universal connection. To perform other cleaning tasks, the cleaner must have a separate manual cleaning device with its own handle and its own cleaning nozzle, for example, in the form of a brush.

The principle of operation of the squeegee, described above in the prior art, is quite simple, however, untrained personnel still encounter certain problems, even if the squeegee holders have only one foot-release button. Therefore, there is a need for manual cleaning devices, which, on the one hand, are modular structures and are always operated in the same simplest possible way, regardless of which cleaning nozzle is used.

Description of the invention

The purpose of the invention is a manual device for cleaning, which is attached to the cleaning nozzle in the most simple and convenient way. In addition, the invention relates to a cover for a mop, which is this type of cleaning nozzle.

The purpose of the invention is a manual cleaning device with the characteristics listed in claims 1 or 2, and a mop cover with the characteristics listed in claims 17 or 18. A preferred embodiment is determined by other claims.

A manual cleaning device in accordance with the invention includes a handle with a handle and a fixing device, in turn, consisting of two fasteners and a cleaning nozzle, which includes two connecting elements arranged and designed so that they are fastened to the fasteners of the handle. Permanent magnets, preferably integrated in plastic, are included in the construction of at least one fastener and the corresponding connecting element, or an electromagnet is included in the construction of at least one fastener. In other words, the mounting of the handle and the cleaning nozzle is provided at least at two mounting points. Each attachment point consists of a fastener on the handle and a corresponding connecting element on the cleaning nozzle. Permanent magnets or an electromagnet are included in the design of at least one such mounting pair, consisting of a mounting and connecting element. To reduce or completely eliminate the formation of corrosion on the magnets during their use in cleaning, permanent magnets or electromagnets are preferably embedded in plastic or non-magnetic metal, for example, in a metal with a low degree of magnetic susceptibility.

Alternatively, the manual cleaning device in accordance with the invention includes a handle with a handle and a fixing device, which, in turn, consists of at least one fixing element and a cleaning nozzle, which includes two connecting elements arranged and designed in this way that they are attached to at least one handle fastener. The design of at least one fastener includes a permanent magnet or electromagnet, which is attached to one or two elements made of the ferromagnetic material of the two connecting elements. Similar to the first option above, the handle and the cleaning nozzle are secured at least at two points of attachment.

Therefore, each attachment point creates a magnetic connection between the handle and the cleaning nozzle.

The advantage of the technical solution in accordance with this invention is that on the one hand various cleaning nozzles are easily attached to the handle. Since at least one pair of permanent magnets or an electromagnet is included in the design, the handle and the cleaning nozzle are secured by two fixing points of the handle and the cleaning nozzle, and one or both of the mounting points are magnetically connected. Thus, the cleaning nozzle is easily attached to the handle, removed and replaced with another cleaning nozzle. A further advantage of using permanent magnets or electromagnets is that these magnets provide a predetermined tripping force depending on location and strength. The pre-set release force ensures that the cleaning nozzle does not detach from the handle during use, which is undesirable. At the same time, however, the use of a magnetic joint ensures that the specified tensile force is not exceeded. In other words, the attachment between the handle and the cleaning nozzle can be set in such a way that the cleaning nozzle is attached to the handle when used correctly and without any problems detaches from it whenever more force is applied. This happens not only when the operator specifically pulls on the handle, while, for example, holding the cleaning nozzle with his foot, but also in situations, for example, when a dry or wet mop nozzle is caught by the table leg. If in this case the handle is detached from the nozzle of the squeegee, damage can be avoided, because otherwise the cleaning device could hit the table leg sharply, which would lead to the falling of objects standing on the table.

In addition, mounting with magnets also simplifies the mounting itself. Since powerful permanent magnets need only be brought close to each other to center them relative to each other and to establish mounting with each other, mounting the handle and cleaning nozzle can be simplified. You can also create another attachment point using a pair of permanent magnets. In this case, the cleaning service staff can easily attach the handle to the cleaning nozzle. However, in a similar way this is feasible for one attachment point, which is created by permanent magnets and which, as a result, becomes a simple geometrically closed connection on the other side. In this case, the fastening is also simplified, since two fastening and connecting elements can be made in such a way that for fastening the cleaning nozzle to the handle, the first fastening element of the handle is first attached to the corresponding connecting element of the cleaning nozzle, for example, one of two elements in contact with the other element using geometric closure. Further, you just need to rotate the handle until the permanent magnets come close enough to each other to automatically connect to each other. Thus, the cleaning service personnel only need to position the handle directly at the point corresponding to the position of the cleaning nozzle, while there is no need to precisely position the second attachment point, since the permanent magnets will automatically carry out the necessary reverse centering.

If, in accordance with an alternative embodiment, two connecting elements include an element made of ferromagnetic material, the following advantage appears: a replaceable cleaning nozzle is made of inexpensive materials, while a durable handle design that can be reused with various cleaning nozzles includes permanent magnets or electromagnets , which, respectively, are attached to one of two connecting elements made of ferromagnetic material.

According to a preferred embodiment of the invention, the cleaning nozzle is a brush device, a wet cleaning device, a dry cleaning device or a window cleaning device. For professional use, cleaning service personnel often require various cleaning nozzles, so cleaning devices, which are usually presented separately, can be combined to perform various tasks. Thanks to the modular design of the technical solution in accordance with the invention, various cleaning nozzles can be attached to the same handle.

According to one preferred embodiment of the invention, the cleaning nozzle is a mop. This configuration is of particular interest if the mop is made without a handle, i.e. The handle is directly attached to the mop cover. Unlike previous technical solutions for mops for dry and wet cleaning, recognized from the prior art, this cleaning device in accordance with this invention consists of only two separate elements, namely: a pen and a cleaning nozzle, which is a mop. Consequently, the handle attaches directly to the handle. In this case, a mop holder movably fixed to the handle can be dispensed with, as provided in the prior art.

Preferably, at least one fastening element includes an element with a geometric closure, forming a mount with a geometric closure with an additionally formed geometry of the geometric closure of the corresponding connecting element. Various options are possible here. If there are two fasteners, magnets are included in their design, and an element with a geometrical closure is additionally installed at one or both attachment points. In addition, a magnetic connection is established at one of the two attachment points, and an element with a geometric closure is installed at the other attachment point. It is also possible to install elements with geometrical closure at both attachment points, one attachment point will be formed by magnets of the corresponding shape or magnets enclosed in the corresponding profile. Finally, it is also possible to establish a magnetic connection in only one of the two attachment points with an additional element with a geometric closure, while the second attachment point is formed by the fastener and the corresponding connecting element, which in the fixed state has two surfaces located close to each other with high degree of resistance to friction. In the case of installing an element with a geometrical closure, it is preferable to provide the latter in such a way that the geometry of the geometrical closure of at least one handle fastening element includes a protruding element, which should be located in the protruding position by means of spring loading. This is a special opportunity to implement geometric closure geometry. The springing of the protruding element facilitates engagement of the protruding element in the corresponding recess of the corresponding connecting element.

This geometry of the geometric closure is further developed in such a way that the element with the geometric closure of at least one connecting element is a recess in which the protruding element is located; the recess consists of a first region that corresponds to the geometry of the protruding element, and a second region at a slope. Thus, a spring-loaded lock is formed, which is detached without any unlocking mechanism on the handle. To lock, the spring-loaded protruding element extends into the recess in the corresponding connecting element when the spring is not pressed. For disengagement, the handle must be moved to a special position relative to the cleaning nozzle, i.e. exactly perpendicular to the cleaning nozzle located on a flat surface. In this position, there is a slope between the recess for springing the protruding element and the outer side of the connecting element on the cleaning nozzle. If the handle is moved to such a specific position, it is removed from the cleaning nozzle when subjected to a predetermined tensile force, while in positions at different angles between the handle and the cleaning nozzle, the connection with the geometric connection between the fasteners on the handle side and the connecting elements on the side of the cleaning nozzle is not lets do this.

According to a preferred embodiment of the invention, the handle fixing device has two articulated arms that are movably connected to each other by an axis; each hinge lever supports a fastener and fasteners pre-stretched in the direction of the connecting elements by an elastic element, preferably a torsion spring, which is located on both hinge arms in the region of the axis. Such a handle configuration is particularly preferred for attachment using at least one attachment point, i.e. the fixing element of the handle and the corresponding connecting element of the cleaning nozzle in the combination of geometric closure. When using articulated levers, two fasteners, respectively mounted on the articulated arm, are previously stretched outward. In other words, with the help of spring-loaded articulated levers, the two fasteners of the handle move in the direction from each other and, thus, are significantly removed from each other in the direction perpendicular to the longitudinal extension of the handle. If the corresponding connecting elements are located on the cleaning nozzle in such a way that their contact areas in contact with the handle fasteners are directed to each other, the handle fasteners are then compressed by the elastic element in the direction of the contact elements and, thus, a secure connection is established between each fastener and corresponding connecting element. The design of the manual device for cleaning also includes an actuator in the area of the handle, the operation of which changes the position of at least one fastener and / or element with a geometric closure. For the operation of at least one fastening element on the gripping side and / or an element with a geometric locking on the handle, any options recognized from the prior art are possible. Thus, it is possible to install fasteners on the articulated arms, wherein each articulated arm will be delivered in a stretchable member, such as, for example, a Bowden cable, which provides operation of at least one fastener with a work member located in the handle region . Another option involves the installation of a movable sleeve in the area of the handle, which moves in the direction of the axis of the handle and in a displaced state acts on one or both articulated levers as a carrier of the fastener. When the sleeve is moved in the direction along the axis, the position of one or both fasteners changes preferably in the direction perpendicular to the longitudinal extension of the handle and preferably in the direction of the longitudinal axis of the handle. As well as a change in the position of at least one work item, a similar change with geometric closure within the work item relative to its position is possible. The change of position involves the axial displacement of the protruding element with a geometric closure, as well as the rotation of the element with a geometric closure so that the latter is in contact with a recess of the corresponding shape in the connecting element and after disengaging the working element in the handle area, it moves to its original position in which there is a lock between the mounting and connecting elements. In the configuration of this type of geometric closure of the connection and, in particular, the blocking described above, special care must be taken not to lose the above advantage of the predetermined disengagement force between the handle and the cleaning nozzle.

According to a further preferred embodiment, the connecting elements of the cleaning nozzle have, respectively, a primary contact surface and a primary contact surface of two connecting elements facing each other and mounted at an angle to each other. The handle fastener has corresponding secondary contact surfaces, the angular direction of which complements the primary contact surface. Here, the angular direction refers to the fact that the contact surfaces are at an angle to any plane in which the longitudinal axis of the handle is located. Thus, by using the angular configuration of the surfaces relative to each other and the corresponding direction of the angular surfaces relative to each other, the required force is achieved to separate the handle from the cleaning nozzle. Thus, the surfaces of the primary contact are angled relative to each other so that in the working position in which the longitudinal axis of the handle is, for example, at an angle from 45 ° to 60 ° to the cleaning nozzle mounted on an even base, it is necessary to apply high force to separate the handle, while in a position where the longitudinal axis of the handle is perpendicular to the cleaning nozzle located on a flat surface, the handle is separated from the cleaning nozzle by applying a small force. According to a further configuration of the present invention, the fastening device includes two fasteners; fasteners on the handle are mounted rotatably on the mounting device. When installing fasteners in the form of a permanent magnet or an electromagnet embedded in plastic, an additional axis of rotation is freely integrated into the magnet cover, so that a magnet with a cylindrical geometry can easily be connected to the handle with the possibility of rotation. The general provision for the installation of fasteners with the possibility of rotation on the mounting device involves improving the operation of a manual cleaning device; when the handle is rotated relative to the cleaning nozzle, the position of the fastening and connecting elements does not change, however, such elements retain a rigid connection with each other, and the fasteners rotate relative to the handle. This leads to the alignment of the axis of rotation of the fasteners relative to each other so that they are perpendicular to the longitudinal axis of the handle.

The actuator includes an element that is located in a direction longitudinal with respect to the handle, preferably a movable sleeve, the movement of which changes the position of at least one fastening element. In particular, this design can be used with sidewalls that spring outward. When installing a sleeve that slides down, these articulated levers moving outward are pressed inward under the action of a torsion spring, so that an additional disengagement of the hard pin joint for at least one magnetic joint is provided.

It is preferable that the tensile force in the longitudinal direction of the handle for disengaging the connection between the handle and the cleaning nozzle is more than 10 N. When the minimum tensile force is set to 10 N, there are no delays in operation due to the unintentional automatic separation of the cleaning nozzle from the handle. In accordance with a preferred embodiment of a manual cleaning device involving the installation of two connecting elements with elements of ferromagnetic material, each magnet is arranged so that both magnetic poles face one of the elements made of ferromagnetic material and are operatively connected to it. Thus, the binding by lines of magnetic induction passing from the magnetic pole to the ferromagnetic element of the connecting element and leaving them is carried out in the direction of the opposite magnetic pole. Using such a device between the dipole magnets and the connecting element of a material with high magnetic susceptibility creates an increased holding force of the magnets.

Alternatively, the permanent magnets are arranged in such a way that only one of the magnetic poles is facing one of the elements of the ferromagnetic material, and the permanent magnet is additionally surrounded by a metal housing that is operatively connected to the element of the ferromagnetic material. This metal case is also made of a material with increased magnetic susceptibility, such as iron. In this case, the metal case, which is also made of a material with increased magnetic susceptibility in order to maintain increased magnet force, performs the function of directing magnetic lines of force from one magnetic pole to another magnetic pole, lengthening the line of force passing through an element of ferromagnetic material in the connecting element , and the metal sleeve surrounding the magnet.

A mop cover according to the invention includes a textile element to which connecting elements are attached; the construction of at least one connecting element provides a permanent magnet that is protected from contact with the liquid. In addition, the dimensions of the flat mop cover are specially designed to maintain dimensional stability; the case attaches directly to the rod-shaped handle. Finally, the attachment elements of the mop cover are arranged and designed so as to form a releasable connection with the handle fasteners. An essential property of the mop cover in accordance with the invention is that it is directly attached to the rod-shaped handle. Therefore, there is no need to install a separate mop holder between the flat mop cover and the handle. At the same time, a flat mop cover is characterized by dimensional stability. The concept of "dimensional stability" here, however, does not mean that the cover for the mop is absolutely rigid; this means that the textile element is flexible, but has constant dimensions, due to which the cover for the mop, in general, retains its shape and weight in the wet state. This means that, for example, when the cleaning device is completely lifted from a flat surface when using the mop cover in accordance with the invention, the flat mop cover generally retains its shape. An advantage of dimensional stability is that when using a mop cover according to the invention, a manual cleaning device can be used, for example for wet cleaning of stairs. In this case, the cleaning device is lifted from a step to a step and transferred to the next upper or lower step. Only the use of a mop cover, designed with sufficient dimensional stability, offers advantages, since it still remains flat when moving to the next step. To clean the railing, it is also important that the cover for the mop has sufficient dimensional stability, because otherwise it will not be able to transmit the pressure created in the cover by the handle.

Alternatively, both connecting elements consist of an element of ferromagnetic material, and the connecting elements of the mop cover are designed and designed to install at least one handle fastener with a permanent magnet or an electromagnet for detachable connection. In this alternative configuration, the flat mop case is also characterized by dimensional stability (see the previous section for explanations), and is attached directly to the rod-shaped handle.

In accordance with one preferred embodiment, the connecting elements are connected to each other by means of a rigid intermediate element designed to maintain a predetermined distance between the connecting elements of the mop cover. This is necessary because When cleaning the mop covers at high temperatures, a certain degree of shrinkage of the textile material is not ruled out. However, since it is important that the connecting elements are positioned directly on the mop cover relative to the handle fasteners, the correct distance between the connecting elements is ensured by connecting the two connecting elements with, for example, a hard clamp.

According to a further alternative embodiment of the invention, the textile element is designed in the form of a pocket and is equipped with a central hole on one side of the textile element for fixing the handle; connecting fasteners are located in the area of the central hole. The installation of the textile element, which has the shape of a pocket, allows you to install various cleaning surfaces with different characteristics on the two main surfaces of the textile element in the form of a pocket. Thus, for example, a surface with a relative roughness is formed on one of the two main surfaces in order to remove existing dirt, while on the other side a surface with increased absorption capacity is created. The term "pocket-shaped" in this regard also means a textile element that is closed on all sides except for the central hole.

Preferably, the textile element is composed of fibers of a diameter of at least 0.5 dtex and a tensile strength of at least 35 cN / tex. These fibers are particularly suitable for ensuring the consistent size of the mop cover. Preferably, the attachment fasteners are stitched, glued and / or welded to the textile element. All three of the above mounting options are possible, so if permanent magnets are installed in the area of the connecting elements, the latter are protected from contact with the liquid. For this purpose, the permanent magnets are preferably completely sewn up with plastic, so that it is possible to sew the connecting elements to the textile element. In addition to the above alternatives, in order to guarantee a reliable attachment of the connecting elements to the textile element, any combination of the above alternative attachment options is also possible. Alternatively, with elements of ferromagnetic material, similar alternative mounting options that provide advantages are also possible.

If the textile element is pocket-shaped, the mop cover also has a tuck in the region of the central hole, which is a closed joint around the central hole and is connected to the two main surfaces of the textile element in the form of a pocket. Such a tuck allows you to close the Central hole so that when using the cover for the mop for wet cleaning, the cleaning fluid does not flow into the pocket of the textile element in significant volumes.

To ensure dimensional stability of the mop cover, regardless of the use of the respective fibers, it is preferable that the mop cover includes one or more reinforcing elements, the structure of which, inter alia, includes connecting fasteners sewn or glued to the textile element and / or inserted into internal pockets of textile element. These reinforcing elements can, for example, be plastic strips that are inserted into the inner pockets of the textile element of the mop cover, and which, due to their location and shape, ensure dimensional stability in a certain predetermined direction. The same applies to the properties of stitched or glued reinforcing elements, the shape and dimensions of which are chosen so that dimensional stability is observed when the inner pockets are exposed in both directions separately. In accordance with one of the preferred embodiments of the invention, the design of the cover for the mop also includes a flexible insert installed together with the connecting elements in the pocket of the textile element. Therefore, as an alternative to the design, according to which the connecting elements are sewn, glued and / or welded to the textile element, an embodiment is created, according to which the connecting elements are connected to the flexible insert. This flexible insert is preferably made of silicone or other flexible plastic. The shape and material of the flexible insert is selected in accordance with the preferred dimensional consistency of the mop cover. In addition, the flexible insert is resistant to temperatures of at least 60 °, so that the mop cover can be washed directly with the flexible insert in it.

In accordance with one preferred embodiment, the flexible insert is sewn into the textile material in the form of a pocket. Thus, the flexible insert cannot be thrown out of the pocket-shaped textile element by mistake, and the mop cover is a monolithic element that is directly attached to the handle in the form of a rod. The flexible insert cannot be compared with the mop holder according to the prior art, since the textile element of the mop cover is not provided separately from the flexible insert, but is a separate structural member. You can also design a mop cover so that the flexible insert is inserted into the textile element in the form of a pocket through an opening in the pocket. In a rectangular textile element, the hole can be located on both long and short sides. If the flexible insert does not extend over the entire width of the pocket, the hole, for example, is positioned so that the flexible insert is initially inserted into the pocket in one direction of the hole, and then moves to the second position in the pocket at the right angle in order to connect the connecting elements to the flexible insert in the area of the central hole.

In accordance with one of the preferred embodiments of the invention, the textile element has two main surfaces, which are in the form of surfaces for cleaning, designed for surfaces of various characteristics, in particular, various degrees of absorption. In addition to varying degrees of absorption, other differences may occur in the characteristics of the two main surfaces.

According to one preferred embodiment of the invention, the mop cover also has a passive electronic component, preferably an RF tag. Tagging simplifies logistics at large cleaning facilities, such as hospitals or airports. The label is triggered when a separate mop cover is activated or is used in any other case of identification of the mop cover. In the case of claims, it can also be proved at what time a particular mop cover was washed. Labels in this case are passive electronic components, since they work reliably in the presence of connecting elements in the form of permanent magnets. In addition, tags are inexpensive to manufacture. Also, if the mop cover is equipped with slots for reinforcing elements, the inner pocket is used in the same way to set the mark, while the pocket is closed with a recess to prevent loss of mark.

It is preferable to manufacture a textile element in the form of a rectangle with two parallel long edges and two parallel short edges; in this case, the connecting elements are located next to one of the long edges, and the structural element, consisting of two connecting elements, is located in the center relative to the nearest long edge. Preferably, the connecting elements have a cylindrical geometry and are located relative to each other so that the side surfaces of the two cylinders are facing each other and are located at a certain distance from each other.

Methods for carrying out the invention

The invention will now be described solely by way of example and by means of the embodiments shown in the figures; in all illustrations, the same components and components are indicated under the same numbers, respectively.

Figure 1 shows a manual device for cleaning, which is generally indicated by the number 10. The term "manual" means the fact that the device for cleaning is not driven by the engine and does not move automatically, but is manually moved by the operator. The manual cleaning device 10 includes a handle, generally designated 12, the construction of which consists of an elongated handle 14, the configuration of which is controlled in a manner standard for the prior art. In the present example, the handle 14 is equipped with a spherical handle 16, given solely as an example. The handle 12 has a fastening device, not shown in FIG. 1, with which the handle 12 is detachably attached to the cleaning nozzle 18. In the embodiment of FIG. 1, the cleaning nozzle 18 is a mop, from which only the mop cover 20 is visible, made in the shape of a pocket.

A manual cleaning device 10 is a modular structure to which various cleaning nozzles 18 are attached, such as a brush, a dry cleaning device or a window cleaner, as follows from the invention described here and in connection with the geometry of attachment of such nozzles; otherwise, the device is manufactured and configured in the standard way. Therefore, in an alternative embodiment of the mop 20, brush brooms or dry cleaning devices or window cleaning devices are not shown.

The handle is adjustable in length. Length adjustment methods are known to those skilled in the art. In addition, the handle 12 can be made so that it rotates relative to the cleaning nozzle 18. When using electromagnets on the handle, you can additionally install a working switch that supplies electric current to the electromagnets from the power source, preferably connected to the handle. The power supply is supplied in this case, for example, in the form of rechargeable batteries. Batteries must have sufficient power to power electromagnets with voltage for more than 8-12 hours. The wiring between the energy source, the drive switch and the electromagnet is carried out according to the standard scheme. Figures 2 and 3 show the connectivity between the lever mechanism 22 on the handle and the cleaning nozzle 18 (not shown further). The nozzle is not shown in the illustrations of the handle and the handle in order to more clearly illustrate the basic elements of the connection between the handle and the cleaning nozzle. The lever mechanism 22 is part of the mounting device 24, as shown further in Fig.9-11 in part of the handle. The lever mechanism 22 is equipped with two fasteners 26, which are securely attached to the fastening device 24 on the handle. These fasteners 26 cooperate with the attachment elements 28, which are securely attached to the cleaning nozzle 18. In the previous example, both the fasteners 26 and the attachment elements 28 are permanent magnets that are fully integrated into the plastic to prevent the corrosive effects of the cleaning liquor or cleaning liquids, containing acid. Both the magnetic fasteners 26 and the connecting elements 28 are arranged so that the connecting elements 28 have contact surfaces facing each other and spaced apart from each other by a predetermined distance. Accordingly, the fasteners 26 also have contact surfaces for connection with connecting elements that are deployed from each other.

For the contact of the fasteners 26 with the connecting elements 28, the linkage is arranged as shown in FIG. 2, where the individual sidewalls 32a and 32b rotate relative to each other, so that the total width as well as the distance between the contact surfaces on the fasteners 26 are reduced. For this purpose, the link mechanism 22 is equipped with a torsion spring or other elastic element that pre-stretches the sides 32a and 32b to the position shown in FIG. 3. However, the position shown in FIG. 3 in this case does not have to correspond to the configuration in which the elastic element completely relieves tension. To improve the connection between the fasteners 26 and the connecting elements 28, additional pressure forces can be similarly created in the region of the contact surface 30 between the fastening elements 26 and the connecting elements 28 by means of an elastic element between the sidewalls 32a and 32b.

In the previous example, the contact surfaces 30 are oriented so that they are parallel to the longitudinal axis of the handle 14. The advantage here is that to release the connection between the handle and the cleaning nozzle, the operator only needs to pull the handle in the longitudinal direction. However, provided that the connection between the handle and the cleaning nozzle does not automatically disengage when the cleaning device is used correctly, a minimum tensile force of 10 N is set in the longitudinal direction of the handle to release the connection between the handle and the cleaning nozzle. This can be done, on the one hand, by the force of permanent magnets, on the other hand, by the depth of sealing of the permanent magnets in plastic, as well as using a predetermined compressive force in the region of the contact surfaces 30. The following methods, shown in the following figures, relate to geometric closure connections between fasteners and connecting elements.

According to the previous embodiment in accordance with FIGS. 2 and 3, on both sides there is a connection of permanent magnets between the fastening and connecting elements. However, in accordance with the invention, it is sufficient that the connection is made with permanent magnets at one point, while the second side, for example, is exclusively a connection with a geometric closure.

4, a linkage mechanism 22 is again schematically shown, the sidewalls 32a and 32b of which protrude away from each other in the direction of arrow A, an elastic element (not shown). For this purpose, the sidewalls 32a and 32b can move relative to the common axis of rotation 34. It is assumed that FIG. 4 schematically shows two different patterns. On the one hand, a movable sleeve 36 is shown schematically, which can move the handle 14 and the corresponding mounting device in the direction of arrow B, i.e. in the longitudinal direction of the handle. When moving the sleeve 36, the outer end 38 of the movable sleeve 36 contacts the sidewalls 32a and 32b and presses them against each other in the direction opposite to the direction of arrow A. The movable sleeve 36 operates using a suitable mechanism on the handle of the handle. For example, it is possible that the top end of the movable sleeve, not shown in FIG. 4, has an inclined surface, and axial movement in the direction of arrow B causes the movable sleeve to rotate about its longitudinal axis. In addition to installing the movable sleeve at the prior art, other kinetic characteristics are also available for moving the sides of the linkage mechanism toward each other.

A second aspect, shown in FIG. 4, relates to a combination of a connection between the fastening elements 26 and the connecting elements 28 as a magnetic connection and at the same time a geometrical connection. For these purposes, on the one hand, the first permanent magnets 40 are mounted on the fasteners 26, and the second permanent magnets 42 are embedded in the connecting elements 28. In the illustration of FIG. 4, only one connecting element 28 is shown. The second permanent magnet 42 has an annular shape. An advantage is that in spite of the recess of the geometrical closure additionally installed in the connecting element 28, the latter can be located close to the contact surface 46 of the joining element 28, since the recess of the geometrical closure 44 is located in the middle of the second annular permanent magnet 42.

The fasteners 26 are also installed with a geometric closure in the form of an elevation of the geometric closure 48, the position and shape of which are selected according to the corresponding deepening of the geometric closure 44 in the connecting element 28, so that in addition to the magnetic coupling, a geometric closure is also formed between the fastening elements 26 and the corresponding connecting elements 28.

Figure 5 shows the fastener 26 and the connecting element 28 in a state of connection with each other. The geometrical lift 48 of the fastener 26 is included in the geometrical depression 44 of the attachment 28. In addition, the first permanent magnet 40 and the second permanent magnet 42 are shown schematically. Both permanent magnets are fully integrated into the plastic 49. In addition, FIG. 5 shows the axis of rotation 50 , which serves to rotate the fastening element 26 to the fastening device 24 of the handle. In the simplest case, the axis of rotation 50 is a metal pin, the fastening of which in the plastic 49 additionally provides one or more annular bulges 52 and which on the side rotated from the connecting element 28, is accordingly mounted for rotation in the mounting device of the handle.

On figa, 6b and 7 shows views of the connecting element 28 (Figa, 6b) and the corresponding fastening element 26 (Fig.7). The connecting element 28 has a recess of geometric closure 44, which is divided into the first region 44a and the second region 44b. 6b, regions are schematically indicated by a dashed line. The first geometric closure recess region 44a generally coincides with the geometry and elevation position of the geometric closure 48, as shown in FIG. The second region 44b is a niche in the connecting element, which extends at a special angle to the first region, as seen in Fig.6a. 7, it is obvious that the rise of the geometrical closure 48 of the fastening element 26 may have a preliminary tension by the elastic element 47, but when a force is applied, the rise of the geometrical closure 48 can also enter the fastener 26 depending on the prestress of the spring in the direction of arrow C. If the handle is separated from the cleaning nozzle, the connection between the fastening element 26 and the connecting element 28 should be disconnected. This is possible when translating the handle at a predetermined angle relative to the cleaning nozzle, for example, if it is perpendicular to the nozzle, and then applying a tensile force to the handle of the handle. The result is an increase in movement in the direction of arrow C and an increase in compression of the elastic member 46; the rise of the geometrical closure 48 moves up the slope in the second region 44b until the rise of the geometrical closure 48 is completely or almost completely pressed into the fastener 26, and the fastener 26 and the connecting element 28 are moved one after the other along the surface of the contact 46 to release the connection . The following alternative configuration of the fastener 26 and the connecting element 28 is shown in Fig. Here, the contact surface 30 is located not parallel to the longitudinal axis of the handle (not shown), but obliquely. The installation of the inclined contact surface with the corresponding direction serves to increase the force between the handle and the cleaning nozzle with an angular location between the handle and the cleaning nozzle prevailing in the ordinary course of business, while the connection between the handle and the cleaning nozzle is easily disconnected when the handle is moved to a position under a special angle to the cleaning nozzle. This may be, for example, the position perpendicular to the cleaning nozzle located on a flat surface or in a position inclined relative to the normal operating position.

In addition, to create an inclined contact surface 30 between the fastening and connecting element, it is possible to similarly change the configuration of two contact surfaces that are in contact with each other by a surface with a high degree of friction, by which the force required to release the joint is further increased. Figure 9 schematically shows a cross section of a manual cleaning device, the handle 14 of which is not shown completely. A manual cleaning device is used with a mop cover according to the invention. This mop cover includes a textile element 52, which is generally made in the form of a pocket, as can be seen in FIG. 11. The textile element 52 as a whole has a rectangular shape with two parallel long edges 54 and two parallel short edges 56. The pocket-shaped mop cover has a generally rectangular profile, as shown in the embodiment of FIGS. 9-11, however this is not a mandatory characteristic of the invention; for specific cleaning purposes, a different geometry can be used in a similar way, in particular since the system according to the invention is modular in which each individual cleaning nozzle is easily replaced.

In the diagram in accordance with Fig.9 shows the connection mechanism described in detail above. The handle fixing device 24 has a link mechanism 22 with two sidewalls 32a and 32b that can rotate relative to each other. Both fasteners 26 are mounted with an axis of rotation 50 and, thus, can be rotatably connected to the sidewalls 32a, 32b. Both fasteners and connecting elements have permanent magnets. The second permanent magnets 42 of the connecting element are inserted into the housing of the connecting element 28, which, in turn, is securely fixed to the textile element 52. This connection, in the alternative, can generally be done by sewing, welding or gluing. In order for the handle fastening device 24 to easily move into the mop joint 20 on one of the two long edges 54, a central niche 58 is installed, as seen in FIG. 11. To prevent the penetration of any liquids into the pocket-shaped textile element 52, it is preferable to close the latter around the central niche with a protrusion 60. The squeegee 20, as described above, with the attachment elements 28 is firmly fixed to the textile member 52 and does not require a conventional squeegee holder, but may Attach directly to the handle in the form of a mop without a holder. At the same time, the mop is sufficiently stable, and the configuration of the fibers used to form the textile element 52 is changed accordingly. In this case, the advantage is proved that if the textile element includes fibers whose diameter is at least 0.5 dtex and the breaking strength of the fibers is at least 35 cN / tex.

In particular, with the exclusive use of permanent magnets as a connecting mechanism between the fastening and connecting elements, it is important to accurately position the connecting elements. At the same time, it must be borne in mind that textile elements can to some extent undergo shrinkage during washing. The problem can be solved, as shown in FIG. 9, by the lever mechanisms 22 used on the handle and small changes in the distance between the connecting elements 28, which return to their initial state by the predetermined voltage of the lever mechanism sidewalls 32a, 32b. A second possibility is the installation of a rigid connecting element 62, for example, in the form of a clamp between the connecting elements.

Figure 9 shows another embodiment of the invention, which is intended to improve the dimensional stability of the textile element 52. For these purposes, reinforcing elements 64 of the textile element 52, which can be manufactured, are installed on one of the two inner sides of the main surfaces of the textile element in a pocket, For example, from elastic plastic. Reinforcing elements 64 are attached to the textile element in any way, for example, by sewing or gluing. You can also install slots 66 from the inside, i.e. the sidewall of the textile element 52 is directed inside the pocket into which the reinforcing elements are inserted. Depending on the desired degree of improvement, the dimensional stability characteristics of the textile element can be set in any direction, as shown in Fig. 9, for example, in the longitudinal, transverse or diagonal direction, as shown in the figure, using reinforcing elements 64a, 64b and 64 from. The shape of the individual reinforcing elements is selected solely on the basis of the example in FIG. 9.

The same applies to the number of reinforcing elements. The pocket can also be used to set the RF tag 72 for electronic identification of the mop 20. However, the label must be secured to the mop and in any other way.

Figure 10 shows an alternative embodiment of the mop 20. As for the handle, there is no difference when compared with the design shown in Figure 9. The connecting elements 28 on the squeegee, however, are part of a flat insert 68 made, for example, of silicone and mounted in a pocket in the textile element 52. The configuration of the insert 68 with the connecting elements 28 fixed to the latter has the geometry shown in FIG. 2 and 3, even if this geometry is described in general form, without specifying the individual parts of the cleaning nozzle in the description of FIGS. 2 and 3. Nevertheless, it is important that when inserting insert 68 no actual changes are required, as it is a mop without a holder, i.e. a mop cover made of a textile element in the form of a pocket is directly attached to the handle in the form of a rod. The use of a mop holder with a mop cover supplied separately is unnecessary. If the mop cover is changed, the handle is detached from the mop 20, and the insert 68 is not removed from the textile element 52.

Reliable fastening of the insert 68 in the textile element 52 is expressed in that the insert 68 is securely sewn into the textile element 52, therefore, after manufacturing, the user cannot remove the insert 68 from the textile element 52 in the form of a pocket. Alternatively, an insert pocket 70 can also be mounted on the side, as shown in FIG. 10 and further shown in FIG. 11. Nevertheless, the insert pocket 70 must be arranged in such a way that after disconnecting the handle from the connecting elements, the insert is not automatically removed from the textile element, but only after precise movement and placement of the textile element 52 in the pocket. Fig. 12 shows the following embodiment of the manual device for cleaning in accordance with the invention, which differs from the designs discussed earlier, only fixing at least one mounting and two connecting elements on the cleaning nozzle. Consequently, with respect to the configuration of the handle, the cleaning nozzle, and also the mop cover, reference is made to the full contents of the previous options. Thus, for example, insert 68 is shown as an example in accordance with FIG. 12; there are other ways; however, the design shown in the following figures provides for the installation of two connecting elements of the cleaning nozzle separately on the mop cover and their sewing, gluing and / or welding on the textile mop cover.

In the embodiment shown in FIG. 12, a locking device 24 is mounted on the handle 12, into which the fastening elements 26 are inserted in the form of permanent magnets or electromagnets. In the case for the mop 20 is an insert 68 to which the connecting elements 28 are mounted so that they are connected to the handle fasteners 26. The connecting elements 28, respectively, have elements 80 made of a ferromagnetic material, i.e. of metal with increased magnetic susceptibility, which can be quickly connected to dipole magnets 26 installed in the mounting device 24 in order to form a safe and detachable connection between the handle and the cleaning nozzle described above. As can be seen from FIG. 13, the dipole magnet 26, being part of the mounting device 24, is oriented so that the north pole, reference N, and the south pole of dipole magnet 26, reference S, are directed to the connecting element 28 of the cleaning nozzle 18. In this case, the connecting element 28 includes a metal housing 80 of ferromagnetic material, for example, a steel insert, which is operatively connected to the magnet 26 by means of a magnet 26 in the connected state if it is near or direct contact with the metal case 80. In this case, the magnetic flux passes between the poles and the magnet, as shown in the magnetic line diagram under reference number 84. To protect the magnet from corrosion, you can additionally install a metal cover 86 on the surface of the magnet 26 facing the metal case 80, as shown in FIG. 13. On Fig shows an alternative arrangement in which the dipole magnet 26 is directed so that only one magnetic pole points in the direction of the metal housing 80. In the direction of the magnet shown in Fig, the desired force is applied using a metal sleeve 82 having the shape of the metal housing surrounding the provided magnet 26, which performs the function of directing magnetic lines of force 84 between the magnetic poles when embedded in an element of ferromagnetic material 80. Thus, and the use of a metal sleeve 82 made of ferromagnetic material with a very low degree of loss, an increased holding force of the magnets between the magnet 26 and the attachment region 28 on the cleaning nozzle 18 is guaranteed.

On Fig shows a possible configuration of the connecting element 28 on the cleaning nozzle 18; in addition, to install the elements 80 of ferromagnetic material (the element shown on the left in FIG. 15 is not visible), an element with a geometrical closure 88 is installed, which, in addition to fastening by the magnetic holding force, creates almost continuous protection against the unintentional detachment of the handle from the cleaning nozzle. In addition, by means of a trough-like body 90 between the individual connecting elements 28, the latter are accurately positioned and, in particular, the distance between them is determined and, in addition, after the fixing device 25 of the handle is installed, their corresponding direction is ensured. This is also evident in FIG. 17, where the handle is inserted. Due to the formation of the closed geometry element 88, the handle fixing device must have a configuration with two articulated arms 32a, 32b that rotate relative to each other, as described in more detail in previous embodiments.

FIG. 16 shows a flat insert 68, which, by analogy with the embodiment shown in FIGS. 15 and 17, has a groove-shaped housing 90 and connecting elements 28 surrounded by elements with a closed geometry 88. In addition, FIG. 16 shows a metal an element made of a ferromagnetic material, preferably of a sheet of metal 100, which is located between two connecting elements. An element 100 made of a ferromagnetic material is shown only in the embodiment of FIG. 16, but can be used separately from such an embodiment and from a trough-like housing in all variants of execution in which at least one of the fastening elements on the handle is a magnet. Element 100 simplifies the operation of the cleaning nozzle. Since various cleaning nozzles can be attached to the handle, the latter are attached to the handle after disconnecting the cleaning nozzle and are stored, for example, in a cleaning trolley. Thus, the user is not distracted by these actions; contact with the element 100 is established by means of a handle and a magnetic fastener, and thus, since re-attachment of the cleaning nozzle to the handle is not required, it rises from the floor, is captured and stored. The element 100 can then also be useful if the cleaning nozzle is detached from the handle during the cleaning process, since the cleaning nozzle, for example, is stuck in a hard-to-reach place and is located, for example, under the furniture element. If the operator attempts to push the cleaning nozzle onto the handle, the element 100 is an additional and easily accessible attachment point for establishing a connection between the handle and the cleaning nozzle, and thus to easily remove the cleaning nozzle from an inaccessible position.

In addition, FIG. 16 shows the design of a flat insert 68 consisting of several ribs 102 connected to each other. The ribbed structure serves to achieve optimum hardening of the flat insert 68 using a minimum of material. Nevertheless, with the geometry of the ribbed structure, a certain flexibility can be set, either in the desired positions of the flat insert, or in general in the longitudinal or transverse direction of the flat insert. The configuration of the flat insert in the form of a ribbed structure, shown in Fig. 16, does not depend on the subsequent characteristics shown in Fig. 16, such as, for example, a groove-shaped housing 90, an element 100, as well as elements with a closed geometry 88 around the connecting elements 28. The flat insert 68 with a ribbed structure, shown in 16, can, for example, be implemented in a form similar to the embodiment of FIG. 10 or 12, as an example. And finally, FIG. 18 shows a manual cleaning device with individual components shown in sectional view of FIGS. 15 and 17. The area with the connecting elements 28 shown in FIG. 15 is part of a flexible insert 68, which is located in the mop cover 20, as already described above in previous embodiments, is inserted, for example, through the hole in the mop cover 20 provided on one from long or short sides, as a result of which the mop cover closes properly, i.e. using stitching or Velcro fastening.

On Fig shows a variant of the cleaning nozzle 18, which can be used as a module with a holder. Instead of a flat insert 68, as shown in FIGS. 10 and 12, the cleaning nozzle 18 has a bottom sheet 92, which has a recess in the upper part, in which there is a groove-shaped housing 90 and connecting elements 28 surrounded by elements with a closed geometry 88. The cleaning nozzle, shown in Fig.19, can be used, for example, with a gripping part, as already described with reference to Fig.4. A lever mechanism is installed here with the sidewalls 32a, 32b, so that the sidewalls and fasteners 26 attached to them can move relative to the axis of rotation 34 in order to locate the fasteners in the region of the groove-shaped housing 90, as well as to rotate them relative to the axis of rotation 34 to supply to the elements with a closed geometry 88 and contact with the connecting elements 28.

The cleaning nozzle shown in FIG. 19 has a harvesting surface 94 and fringe 96, which is also shown in FIG. The cleaning surface 94 has alternating regions 98a and 98b, which differ in different roughness and have different abrasive characteristics. Thus, the cleaning surface 94 can be used to loosen dirt that adheres to the surface, which must be washed with chemical and / or mechanical means, while fringe 96 is suitable for traditional cleaning with the reception of loose dirt and dirt falling off the cleaning surface 94. A wet rag, shown in Fig.19 and Fig.20, cleaned in the usual way in a bucket for rinsing rags, and then squeezed to remove unwanted moisture in the extraction device with the geometry of the cleaning nozzle.

With this invention, a manual cleaning device and mop are particularly suitable for the latter method of use within a modular system. The mop cover is replaced with another cleaning nozzle and in all cases the cleaning nozzles are attached only to the handle in the form of a rod. In addition, providing a connection for at least one pair of permanent magnets makes connecting the handle to the cleaning nozzle particularly easy. Even untrained cleaning service personnel can quickly establish the correct connection, since the magnets have the property of self-centering, and thus, positioning inaccuracies are eliminated. The mop cover according to the invention can be directly attached to the handle. Therefore, this mop does not have a holder. Thus, the mop cover has sufficient dimensional stability depending on the intended application; this is ensured by the textile fibers used to make the mop cover, as well as the corresponding reinforcing elements, which are located in the pocket shape of the mop cover. Appropriate fibers and additional reinforcing elements may also be used in combination. Reinforcing elements are either provided separately from the connecting elements of the mop cover, or together with them in order to minimize the final assembly with fewer individual parts. As a result, the presence of reinforcing elements does not change the fact that when replacing the mop cover, it is not necessary to disconnect the latter from the mop holder, and any new mop cover does not need to be stretched along the mop holder, but it is only necessary to completely disconnect the old cover from the handle and replace it with a new one .
