Definitions

  • the invention relates to a cleaning device according to the preamble of claim 1.
  • the generic cleaning device has in particular a support plate with a working surface which can be applied to the surface to be cleaned.
  • a possible application may be the design of the cleaning device as a floor wiper, however, the invention is not limited thereto.
  • the invention can be used. All these devices are hereinafter referred to simply as a cleaning device.
  • a cleaning pad for example in the form of a cloth, a sponge, a grinding surface or a Kehransatzes be attached via a Velcro connection such that the cleaning pad is held on the, the surface to be cleaned facing working surface ,
  • at least one holding element is provided, which has a Velcro hook with Velcro surface for attachment of the cleaning pad.
  • a wiper for attachment to a cleaning device of this kind is from the DE 10 2010 03 568 A1 known.
  • This wipe is connected via a Velcro connection to the underside of a mop holder and is multi-layered. It has an upper, liquid-storing layer on which a klettsorter mounting strip is arranged directly or indirectly, via which the wipe can be attached to the underside of a support plate of the cleaning device.
  • the wipe can be well moistened, as it has the liquid-storing layer and when used in conjunction with a suitable Cleaning device would lie directly under the moisturizing moistening, but the attachment of the wipe on the Velcro connection is not optimal, since the holding forces of the Velcro connection have a relatively large Velcro surface.
  • a wiper device with movable Velcro surfaces is from the US 2013/0340187 A1 known.
  • the wiper plate movably mounted carriers for hook and loop areas are pulled away from the wipe in the transverse direction, whereby the wipe is thereby torn off the hook and loop surfaces.
  • this has the disadvantage that there is a risk that the wipe is pulled into the openings of the Velcro and also damaged by the high tensile forces.
  • a wiper which is connected via a so-called mushroom hook and loop connection with the mop plate, is from the US 5607345 A1 known. Although this connection is firm, but has the disadvantage that the risk of damage in improper removal of the wipe in the more obvious, perpendicular to the mop plate direction.
  • the object of the invention is therefore to provide a cleaning device in which the attachment via the Velcro connection has a higher strength and smaller Velcro surfaces are possible.
  • the cleaning device according to the invention is preferably characterized in that the Velcro surface with the Velcro hooks is movable relative to the work surface and the Velcro hooks have a, from the Velcro surface extending pin-like shaft and at the free end of the shaft in at least one transverse direction extending head portion, wherein the relatively movable to the work surface Velcro surface is movable such that the Velcro elements are at least in a different from the vertical to the working surface angle, but preferably also in the direction perpendicular to the work surface direction.
  • the secure hold of the cleaning pad on the support plate is realized on the particular configuration of the Velcro connection.
  • This Velcro connection has Velcro hooks, which have a lower, pin-like shaft, with which they on the holding element or are attached to the holding elements. This can be done via a conventional adhesive joint, in this respect, the Velcro surface does not necessarily differ from the classic Velcro fasteners.
  • the head region will protrude outward in several or all directions so that it may, for example, have the shape of a small mushroom.
  • the head regions may be not only mushroom-shaped or plate-shaped, but also L-shaped or T-shaped or also have any other shape which has a lateral extension, preferably extending in at least one of the directions perpendicular to the shaft.
  • Such a Velcro connection is also known under the name mushroom hook and loop fastener and is sold, for example, under the brand name 3M DualLock by the company 3M Germany GmbH.
  • the cleaning device should be provided with a secure attachment between the cleaning pad and the support plate or or additionally, the attachment should be possible via a small held Velcro.
  • the user should be enabled to remotely release the cleaning pad from the carrier plate. This can be followed by a separate actuating mechanism or by a suitable embodiment of the carrier plate itself, as will be described in detail below.
  • the hook and loop fasteners used in connection with the present invention have the advantage that they provide increased protection against peeling in the direction perpendicular to the cleaning pad. At the same time, however, they also have the further advantage that they are relatively easier to detach in a transverse movement when the parts connected via them are moved. This effect is now utilized according to the invention in order to optimize the attachment of the cleaning pad to the carrier plate.
  • the movement used in a transverse direction for the lower hook can additionally be superimposed on a movement in a direction perpendicular to the working surface or can be followed or connected upstream in time. This can be done via a longitudinal movement or a rotational movement in a thread-like screw, alternatively, the Velcro hooks can also be arranged on holding elements which are obliquely, for example, guided along oblique planes, so that they not only in the direction of the But also move the carrier plate transversely to the carrier plate.
  • the support plate has for attaching the cleaning pad on the holding elements.
  • These holding elements are provided on their underside with the Velcro surface, wherein the holding elements are arranged next to or in the carrier plate so that they jump out of the plane by a preferably rather small distance.
  • the head area used as hook areas of the hook and loop elements project out of the plane of the work surface.
  • the support plate can now be placed on a velcro-cleaning surface, for example, on a wipe, with the slightly downwardly projecting hook and loop fasteners connect with the material of the cleaning lining in that the hook and loop elements are pushed up and move laterally or turn. As a result, then hooked the Velcro connection. This can be done by the pressure force of the user or even by the weight of the cleaning device, which may be sufficient, for example, to move the rotatable or laterally slidably mounted holding elements in the storage.
  • the provision of a single retaining element may be sufficient to implement the invention.
  • This can, for example, similar to the frame-like brush of the nozzle of a vacuum cleaner, run around the support plate around and so completely grasp the edge of the cleaning pad.
  • a complete, peripheral detection of the edge is not always necessary, it may also be sufficient to connect only one edge of the cleaning pad to the carrier plate, so that the underlying area of the cleaning pad can be pulled behind the connection, for example.
  • a preferred embodiment of the invention has a plurality of holding elements that hold the cleaning pad on the support plate at different locations. These holding elements are for example distributed over the underside of the carrier plate, so that the cleaning pad, without it would hang down when lifting the carrier plate, is held on the underside of the carrier plate.
  • the invention can be exploited to solve the cleaning pad again.
  • the retaining element can be pulled even further into the carrier plate, so that shear forces occur in the area of the Velcro connection, which release the Velcro connection.
  • the retraction of the holding elements can be done by placing the support plate on an abutment, such as the edge or a shoulder of the waste container, or via a user-operable actuator.
  • a movable support member will be provided on the support plate, from which extend the holding elements with the Velcro down through recesses in the work surface.
  • the gap between the work surface and the support members is then so small in the case of a textile or other flexible cleaning pad that retraction of the cleaning pad does not occur in the recesses, this being possible only in that the Velcro connections according to the invention because of the special shape of the Velcro elements can be kept very small.
  • the transverse movement of the hooks is preferably realized in that the holding elements are mounted in a thread-like screw, so that not only the movement perpendicular to the support plate, but also in the transverse direction results from this fferlagerung, as a depression of the holding elements in the fferlagerung automatically their rotation and thus to a transverse movement is not concentric with the axis of rotation Velcro leads.
  • the twisting of the retaining elements in the erlagerung is initially used to hook the cleaning pad with the Velcro elements.
  • the user simply sets the support plate on the cleaning pad or pushes the support plate in handheld devices on the cleaning pad.
  • the holding elements which are now slightly protruding from the plane of the underside of the carrier plate, can now be pressed inwards into the carrier plate. Since at the same time by the leadership of the holding elements in the, provided in the support plate storage their transverse movement is realized, the head portions of the Velcro hooked to the top of the cleaning pad.
  • Velcro elements with the flattened head area has the additional advantage that damage to the surface to be cleaned can be avoided, since even with very thin cleaning surface, in particular in the form of antistatic cloths, for example Velcro elements can no longer come into contact with the surface with pointed end areas, which has hitherto brought with it the risk of scratches in the case of classic Velcro connections and thin cleaning coverings. Also, the installation of the cleaning device without cleaning surface could lead to scratches or an unwanted hooking with, for example, textile floor coverings. Since the holding elements are movably mounted, they can move upwards on a sensitive surface when setting up the carrier plate and will not exert any critical pressure force on the surface.
  • the Velcro connection will now remain firmly fixed, since further movement of the holding elements after pressing into the storage in the carrier plate no longer takes place.
  • the holding elements can now be moved out of the storage again so that they stand out of the plane of the underside of the carrier plate out again, so take their initial position again. This can be done for example by pure gravity when the support plate no longer stands up on a surface to be cleaned.
  • This actuating device can be, for example, a cable pull, which makes it possible to move the holding elements relative to the remaining area of the carrier plate in the desired direction.
  • a possible embodiment of the invention may be, for example, a floor wiper, the support plate has an inner support member to which the holding elements are attached. This inner support member may then be slidably mounted in the remaining region of the support plate, wherein the underside of the support plate has recesses through which protrude the holding elements with the Velcro areas.
  • the support member can be moved in this embodiment, for example, by placing it on a floor upwards, wherein the rotatably mounted on the support member retaining elements are mounted in a screw on the underside of the support plate, so not only move together with the support member up, but themselves simultaneously forcibly turn.
  • the contact area with the cleaning pad is firmly connected to the Velcro elements.
  • only a slight displacement of the holding elements and a small rotational movement are necessary.
  • the user places the cleaning advisor with the carrier plate on the cleaning pad.
  • the retaining elements and the Velcro elements hook with the head areas in the surface of the corresponding region of the cleaning pad.
  • a locking device may be provided, which lock the holding elements or, if present, the carrier plate in the depressed state.
  • This has the advantage that the user can lift the cleaning device without the risk that the cleaning pad accidentally falls down. This facilitates the implementation of the cleaning device and prevents the unintended fall off of not yet used cleaning surface.
  • the latching can be achieved via the actuating means in the embodiment described above.
  • a cable may be provided on the style, which can be tensioned by the user via a handle and releases the catch in the carrier plate. Subsequently, the support element can then drop gravity driven again.
  • springs can also be provided between the holding elements or the carrier element and the remaining regions of the carrier plate, which press the holding elements or the carrier element back into the release position after releasing the latching connection.
  • Another embodiment of the invention solves the Velcro connection in that the holding elements are further retracted into the carrier plate.
  • the holding elements may be mounted in the carrier plate so that they are first rotated, as described above, in a first locking direction.
  • Further pulling up the holding elements can then cause a reversal of direction of the rotational movement, whereby the locking of the head portions of the Velcro connection is released, so that on the one hand the strong hold of the particular Velcro connection and on the other hand by the above-described shear forces of the cleaning pad is released from the holding elements.
  • the direction reversal rotational movement can be realized for example via an opposite sense thread in the upper region of the mounting of the holding elements.
  • the movement of the holding elements necessary for this purpose can then be effected by an actuating device which, for example, is capable of sufficiently pulling the holding elements mounted on the carrier element into the bearing.
  • the carrier element can be pressed into the carrier plate by the force which is exerted on the surface to be cleaned when the carrier plate is pressed on.
  • the actuating force is transmitted to the movement of the retaining elements of these themselves on the support element.
  • the support member may also have separate supports, which may be provided penetrating laterally or the support plate and transmit a force from the surface to be cleaned on the support member. These can then be used as adjusting means to displace the carrier element when hiring or pressing the carrier plate to the surface.
  • the retaining elements are displaced by placing the carrier plate on the edge of a waste container further in the release position.
  • the support element described above can protrude outward from the support plate with support regions, wherein the geometry is adapted to the geometry of the waste container, so that upon immersion of the support plate in the waste container results in a conditioning of the support areas to the edge of the waste container. This can then lead to the force transmitted by the support areas pushing the carrier element upwards, or the holding areas then turning on the one hand again and on the other hand removing from the cleaning coating, which then leads to the solution of the Velcro connection.
  • the cleaning device is designed as a floor wiper.
  • this floor wiper allows humidification of the cleaning pad.
  • the carrier plate may have a moistening distributor, which is able to dispense moisture downwards in the direction of the cleaning pad then formed as a wiping cloth.
  • the wiper is formed in this embodiment so that on the one hand it is suitable to cooperate with the special Velcro connection. On the other hand, it must be able to transport the moisture provided either to the surface to be cleaned or, in the case of a further preferred embodiment, also to store it, that is to store it.
  • the wipe can be formed in multiple layers, with a middle layer serves as a moisture-storing layer.
  • the cleaning layer is provided below this moisture-storing layer and has the necessary properties, for example, to be able to scrape off dirt or to gently clean the surface.
  • a water-permeable layer may be provided which consists of a water-permeable material.
  • the water permeability of this layer can also be achieved by extending this upper layer only over the edge region of the wipe, so the middle area remains free. This is then the area through which the moistening distributor can deliver the moisture into the wipe, so that in particular in an absorbent, moisture-storing layer then distributed in this layer, the liquid distributor of course also by the working pressure and the movement of the support plate along cleansing surface takes place.
  • the viable area can then be provided in this embodiment, which does not necessarily have to be liquid-permeable.
  • the individual layers of the wipe can be sewn or needled together, so that there is a solid bond.
  • the invention is usable independently of the embodiments described above in connection with all types of cleaning equipment.
  • the moistening of a cleaning pad is merely to be understood as an optional feature, just as well, for example, provided with a bristle surface or a grinding surface on the support plate may be provided.

  • the support plate 1 is formed substantially rectangular and has two opposite longitudinal sides. Parallel to these longitudinal sides, two rows of four retaining elements 6 are provided here, which penetrate the lower side of the carrier plate 1 with cylindrical areas.
  • velcro surfaces 8 are provided at the lower regions of the holding elements 6, which have hook-and-loop elements which do not protrude in the rest region or only with a small portion out of the plane of the underside of the carrier plate 1 forming the working surface A. These Velcro elements can then be used with a suitable surface of only in the FIGS. 2, 3 and 5 to 9 visible cleaning pad 5 are connected when the holding elements 6 are pressed by pressure of the support plate 1 in this.
  • the retaining elements 6 can be pressed together with the Velcro surfaces 8 in pressure in the receptacles 7 of the support plate 1, a scratching of the soil during installation of the cleaning device without cleaning pad 5 in conjunction with the flattened head portions of the Velcro elements can be additionally avoided.
  • FIGS. 2 and 3 is the support plate 1 off FIG. 1 in a view on the long side ( FIG. 2 ) as well as on the transverse side ( FIG. 3 ).
  • the support plate 1 has a hinge 16, via which it can be connected to a style of the wiper device.
  • a distribution port 4 is provided, which is on the one hand with the two humidification distributor 2 and on the other hand (not visible here) in fluid communication with a pressure-operated supply for liquid of the cleaning device.
