Definitions

  • the invention concerns a flat mop including a support plate that is connectable with a mop cover.
  • Flat mops such as described above are generally known.
  • One example of such a flat mop includes a rectangular support plate with the support plate enclosed by a pocket-shaped, rectangular mop cover that is open on one of its longitudinal sides. Dry, unused mop covers are pulled onto the support plate by hand.
  • An object of the invention is to further develop a flat mop of the previously known type to provide simplified handling, in particular, such that a used mop cover can be removed from the support plate without direct contact with the user's hands.
  • a flat mop that includes a support plate that is connected with a mop cover.
  • the support plate has a stripper for the removal of the mop cover from the support plate.
  • the stripper can be employed without the user having to touch the mop cover with his hands.
  • the changing of the mop cover is thus implemented in a simple and hygienically satisfactory manner.
  • the support plate can be covered with the mop cover in a form-locking manner.
  • the mop cover is made, for example, in the shape of a pocket and rectangular.
  • the mop cover can have a closed longitudinal side and two closed transverse sides and an open longitudinal side, into which the support plate is introduced and thus is connected with the mop cover.
  • the corners of the open longitudinal side reach, in a form-locking manner, around the corresponding corners of the support plate.
  • the support plate can have at least one corner that is enclosed in a form-locking manner by the mop cover.
  • the stripper for the removal of the mop cover may be arranged so it can swivel around the corners.
  • the mop cover For the removal of the mop cover from the support plate, the mop cover is pulled down by the stripper around the corners of the support plate. Subsequently, the mop cover falls independently off the support plate, especially if the mop cover is wet and heavy after use.
  • the stripper can be made of a polymeric material.
  • Polymeric materials as compared for example to metal materials, have the advantage that they are light and rust-free and are thus particularly suitable for use in cleaning devices. Furthermore, polymeric materials can be frequently processed in a simple and low-cost manner, so that the components thus produced (e.g., the support plate) can be manufactured simply and at low cost.
  • the stripper can be configured as a folding lever.
  • a folding lever is a component that can be simply produced and can be simply connected with the support plate. The movement course of the folding lever is immediately clear for the user. In this way, the function of the folding lever and the mode of its operation are self-explanatory.
  • the folding lever can be made substantially flush with the surface of the support plate.
  • the substantially surface-flush integration of the folding lever into the support plate during use of the flat mop enables the mop cover to be uniformly pressed on the floor and thus enables a uniform cleaning result. Additionally, this configuration produces no disturbing projections that could hinder simple assembly or dismantling of the mop cover. Furthermore, the cleaning of the support plate following use of the flat mop is simplified. The smooth surface minimizes the danger of the folding lever causing an injury to the user.
  • the folding lever can have a U-shaped profile that is located on a congruently designed guide bridge of the support plate during the proper or normal use of the flat mop.
  • the guide bridge is thereby a component of the longitudinal side of the support plate. If the folding lever is held on the guide bridge with a U-shaped profile, then the folding lever fits into the support plate so the folding lever is flush with the surface.
  • the connection of the folding lever with the guide bridge is preferably carried out in a force-locking manner with clamps.
  • the clamping force with which the folding lever is situated on the guide bridge is dimensioned or selected such that the folding lever is held securely on the guide bridge when the flat mop is properly used and can be detached from the support plate by the user of the flat mop in order to strip off the mop cover without any problems even if the folding lever is moist and/or slippery.
  • the folding lever can be brought to a stripping position against the elastic force of a retaining spring.
  • the retaining spring provides additional security against an unintended detachment of the folding lever from the guide bridge. Furthermore, it is advantageous if the folding lever to a large extent automatically springs back to its starting position following the stripping of the mop cover from the support plate. The handling of the flat mop is thus simplified.
  • the stripper can be formed by a strap that is articulated in the corner and that can swivel around the corner. As compared to the previously described folding lever, a strap can be produced more simply and with an even lower cost. Due to the simple construction, a damaged strap can be replaced by a user quickly and simply. A provisional repair, for example, can be easily done using a cable strap forming a loop.
  • the stripper can be conducted in a sliding block guide in the support plate and can swivel around the corner.
  • a sliding block guide can be designed, for example, in the shape of a simple slit in the support plate with the slit in the plate extending from the plate parallel to the longitudinal side of the support plate.
  • Such a sliding block guide can be produced simply and at low cost, but, as compared to the articulation or joint described below, has disadvantages with regard to the handling of the stripper.
  • the folding lever can be connected with the support plate with an articulation or joint located in the corner.
  • Such a joint has the advantage that the folding lever is always defined and moves the same way and is conducted exactly through the joint.
  • the dismantling of the mop cover from the support plate is carried out by swiveling the folding lever to the stripping position through the open longitudinal side of the mop cover around the joint located in the corner, until the folding lever carries along the mop cover, located in a form locking manner over the corner, beyond the corner and, in this way, the mop cover falls from the support plate.
  • the joint can be formed by an axle located in the corner, around which the folding lever can swivel.
  • the joint can be formed separately and the axle formed by a sleeve, which is located in the support plate and around which the folding lever can swivel.
  • the joint can be configured, in part, as one piece or unitary with and uniformly made of the same material as the folding lever.
  • the axle around which the folding lever rotates can form a one-piece component of the folding lever and snaps in a fork-shaped holder of the support plate.
  • the fork-shaped holder is thereby located, for example, on the end of the guide bridge, which leads into the end around which the mop cloth is pulled.
  • Both the axle, constructed as one piece with the folding lever, as well as the fork-shaped holder can be made of a polymeric material.
  • the fork-shaped holder is preferably designed as one piece with the support plate and is uniformly made of the same material.
  • the joint can be formed by a film hinge, which extends around the corner.
  • a film hinge which extends around the corner.
  • the film hinge must thereby be designed in such a manner that it is sufficiently dimensionally stable to strip the mop cover over the cover of the support plate while being sufficiently elastic so as to also not fatigue/break in continuous operation.
  • Such a design ensures that the flat mop has consistently good usage characteristics during a long period of use.
  • the film hinge can be designed as a separate component and can be affixed to the support plate.
  • the affixing can be carried out, for example, by a screw connection. If necessary, the stripper and/or the film hinge can be replaced independently of the support plate.
  • the film hinge can be designed as one piece with and be made uniformly of the same material as the support plate. The manufacturing is thus simplified.
  • the joint can be made of a polymeric material.
  • the joint can thus also be made rust-free, lightweight, and in a simple manner.
  • the folding lever can have an actuation handle on the side turned away from the joint.
  • the actuation handle can simplify the stripping of the mop cover from the support plate without direct hand contact. The user grips the actuation handle and, in this way, leads the folding lever to the stripping position.
  • the actuation handle can be made of a rubber-elastic material. Such a construction has the advantage that the actuation handle can not break off, is durable for a particularly long time, and when mopping, cannot damage, for example, the surface to be cleaned and/or the furniture standing on the surface to be cleaned, regardless of the mopping direction of the flat mop.
  • the support plate can be made rectangular with two longitudinal and two transverse sides.
  • the mop cover can be designed in the shape of a pocket that is closed on three of its sides.
  • one of the longitudinal sides of the mop cover and the two transverse sides of the mop cover can be designed closed and the other longitudinal side of the mop cover, which is open for the introduction of the support plate into the mop cover, can have closed corners for the form-locking holding of the mop cover on the support plate.
  • the mop cover preferably has two mopping surfaces.
  • the two mopping surfaces can be the same or different with regard to their characteristics. In this way, either cleaning can be carried out with a mop cover for a particularly long time or surfaces with different degrees of soiling can be cleaned, for example, in stages.
  • the one longitudinal side of the support plate that is associated with the open longitudinal side of the mop cover can thereby have an opening through which a shaft, preferably connected via a cardan joint with the support plate, can be swiveled.
  • the closed corners can cover 20 to 50% of the length of the folding lever.
  • the cover is selected such that a reliable form-locking connection of the mop cover with the support plate exists while allowing, if necessary, the mop cover to be stripped from the support plate.
  • the closed corner covers 30% of the folding lever, regarded from the joint, in the direction of the folding lever.
  • the support plate can be designed in a trapezoidal shape, with the shorter longitudinal side of the support plate enclosed by the closed longitudinal side of the mop cover.
  • the described trapezoidal shape has the advantage that the stripping of the mop cover from the support plate without direct hand contact takes place in a particularly reliable manner.
  • the corner, around which the mop cover is pulled from the support plate, located on the longer longitudinal side the mop cover, pulled over this corner by means of the stripper, will slip with particular ease from the support plate without remaining hung on the transverse side of the support plate.
  • room corners can be cleaned particularly well.
  • the open longitudinal side of the mop cover is surpassed toward the outside by the actuation handle. Such a development is sensible, so as to be able to grip the actuation handle without coming into direct hand contact with the mop cover.
  • the support plate can include a tension element and in this way, can be designed for stretching a mop cover with a change in the length.
  • the tensioning element can be acted on by the force of a spring in the longitudinal direction of the support plate.
  • Such a support plate is necessary when using a mop cover that is largely inelastic, so as to be able to cover the support plate with the mop cover in a form-locking manner.
  • the longitudinal sides of the support plate and mop cover are of substantially equal length, with the open longitudinal side of the mop cover with the closed corners having only one opening for the assembly on the support plate, which opening is shorter than the longitudinal side of the support plate.
  • the support plate must be pushed together to a shorter dimension until it is completely situated within the mop cover and subsequently returns to its original size.
  • the mop cover then tautly encloses the support plate.
  • a variable length of the support plate for the assembly with the mop cover could also be achieved by designing the support plate to be pliable and elastically yielding.
  • the support plate thereby can be elastically deformed to be assembled with the mop cover. With such a development, therefore, a separate tension element is not necessary.
  • the lower dimensional stability of the pliable and elastically yielding support plate can be sufficient for a taut assembly of the mop cover on the support plate.
  • the invention provides a support plate for a flat mop, as previously described, including a stripper for the removal of the mop cover from the support plate.
  • Such support plates can easily replace existing support plates so that the known flat mops can be operated with a support plate according to the invention so as to enable a removal of the used mop cover from the support plate without direct hand contact, as previously described, in a simple manner.
