Definitions

  • the invention relates to a cleaning device for wet, damp or dry wiping of floors with a handle and an elongate holder for a mop cover fastened pivotably thereon via a joint.
  • the holder consists of at least two parts which can be rotated relative to one another about an axis which is horizontal in use (foldable).
  • the handle is attached to only part of the foldable holder.
  • This holder part is also referred to below as the main part, the other holder part as a folding part.
  • the pivot axis of the handle is aligned parallel or obliquely to the folding axis of the holder.
  • the cleaning devices usually consist of a holder, a rigidly or movably attached handle and the mop cover attached to the holder.
  • the mop cover lies against a rectangular, elongated holder, so that the active cleaning underside of the mop cover (flat mop cover) lies with its entire surface on the floor in use.
  • Flat wipers with a plate-shaped or with a holder consisting of a wire frame are known.
  • the present invention is directed to a cleaning device with a foldable holder for wiping covers which can be detachably attached to it.
  • the foldable holders which are also called folding holders, have the advantage of allowing the flat mop cover to be opened and removed quickly.
  • the narrow sides of the unlocked holder which is usually opened in the transverse direction and thus shortened, are introduced in the direction of the longitudinal axis into corresponding insertion pockets on the narrow sides of the mop cover. The holder is then unfolded again and locked in this position.
  • the locking devices of the known folding holder must be robust and strong so that they can withstand the great forces exerted by the wet mop covers on the narrow sides of the holder when the cleaning device is lifted from the floor.
  • the long lever arms from the narrow sides to the folding axis of the holder reinforce this effect.
  • the increased manufacturing effort necessary for this reason represents a further disadvantage of known cleaning devices with folding holders.
  • a cleaning device with a rigid, that is, not foldable holder is described, for example, in German utility model DE 1 784 359 U.
  • the manufacturing costs and the susceptibility to faults are lower compared to folding holders, but a laborious fastening of the cover on the holder and a corresponding laborious removal of the cover must be accepted will.
  • ball pins are provided on the holder, which engage in corresponding holes in the cover.
  • the invention is therefore based on the object in a cleaning device of the type mentioned significantly reduce the manufacturing costs and the susceptibility to malfunction of known folding holders and at the same time to enable a quick, problem-free and easy removal and fitting of the mop cover.
  • the folding axis has a sufficient distance from the location of the attachment of the handle to the holder, so that the part of the holder attached to the handle, the main part of the holder, points upwards when the handle is lifted.
  • the pivot axis of the handle and the folding axis of the holder are offset from one another by a minimum distance. This has the consequence that when lifting the stem and thus the stem directly attached main part, the weight of the folding part pulls the folding axis downwards and thus presses the end of the main part opposite the folding axis upwards in the manner of a lever.
  • the folding holder therefore remains essentially in its elongated, flat state, so that an opened mop cover does not slip off.
  • a locking mechanism for the folding holder is neither necessary nor provided. The problems occurring with the known locking devices therefore do not arise in the folding holder according to the invention.
  • the holder It is essential in the invention for a given mass distribution of the holder to have a sufficiently large distance of the folding axis from the mounting location of the handle on the main part, so that the weight of the folding part exerts a sufficiently large torque on the main part to pivot it into the desired position. If, on the other hand, the specified minimum distance, which can easily be determined by experiment, is not maintained, the torque exerted by the weight of the folding part is not sufficient, and the holder takes the shape of an inverted V when the handle is lifted, so that the Mop cover slips off the holder.
  • the procedure for opening and removing the flat mop covers is as follows.
  • the underside of the mop cover lies flat on the floor.
  • the outer end of the folding holder main part opposite the folding axis points upwards, as has already been stated.
  • the downward-facing edge of the folding part can be pushed into one of the two insertion pockets of the mop cover.
  • the end of the folding holder main part pointing upwards is pressed down, so that the holder folds up and is thus in the shortened state.
  • the edge of the main part, which was pointing upwards can be inserted into the other insert pocket of the flat mop cover.
  • the flat mop cover is removed from the folding holder in a corresponding manner.
  • the folding axis of the holder according to the invention can be aligned in any direction.
  • it can extend transversely to the longitudinal axis of the elongated holder.
  • the folding axis runs essentially parallel to the longitudinal axis of the holder and that the mop cover has an insertion pocket opening towards the center on each long side.
  • the mop covers to be applied to the foldable holder have a relatively high proportion of cotton in order to ensure sufficient absorbency.
  • the cotton content leads to a shrinkage when washing the mop covers, especially at higher temperatures, and thus to a shortening, especially of the long sides of the mop covers. This shortening varies depending on the type and number of washing processes.
  • the known mop covers must therefore be manufactured with a relatively large tolerance range. In the case of the usual mop covers with slide-in pockets attached to the narrow sides, the difficulty arises that the covers are either too tight or too loose. In the latter case, the covers slide partially under the holder during use, making the wiping process more difficult.
  • the construction of the folding holder according to the invention can be different.
  • holders made of wire frames are in the Scope of the invention.
  • the holder is designed as an elongated, essentially rectangular plate. It is preferably made of plastic.
  • the holder edges should be beveled to facilitate insertion into the pockets of the mop cover.
  • a special joint is also not required, with which the handle is attached to the holder. It is only essential that the folding part of the holder is able to press the main part of the holder with its outer end upwards when lifting the handle. In addition to the distance between the folding axis and the pivot axis of the handle, it is necessary according to the invention that the pivot axis of the handle forms an angle deviating from 90 ° with the folding axis of the holder. A parallel alignment of the pivot axis of the handle and the folding axis of the holder is not absolutely necessary, but is generally advantageous.
  • the handle is connected to the holder via a cardan joint.
  • This joint which can be swiveled in all directions, simplifies the wiping of floors with corners and edges and protruding furniture pieces and parts.
  • the parts of the holder which can be rotated relative to one another can only be folded downward.
  • the terms “below”, “above” are understood here and also in the rest of the description and the claims when the cleaning device is aligned during use, that is to say with a holder lying flat on the floor and a handle pointing upwards.
  • the foldability of the holder is blocked upwards, for example by a corresponding design of the folding mechanism.
  • the main part of the holder attached to the handle is only pushed up until the holder parts lie in one plane. It is not possible to swivel beyond this, which would cause the mop cover on the holder to bend with its cleaning-active underside.
  • the folding axis has a sufficient distance from the location of the attachment of the handle to the holder, so that the folding part exerts a sufficiently strong, downward force on the folding axis when lifting the handle, so that the main part moves away from the horizontal position moved to the substantially vertical position.
  • the joint of the handle is attached directly to the top of the main part of the folding holder.
  • the stem joint may need to be relatively close to the outer edge of the body of the holder.
  • the intermediate piece proposed in this embodiment of the invention thus fulfills the requirement according to the invention for the sufficient distance of the folding axis from the location of the handle attachment, so that the handle or its joint above any position of the folding holder and thus also in the advantageous Location may be immediately above the folding axis.
  • the intermediate piece extends into the central area of the holder and the articulation of the stem is fastened to the intermediate piece in this area, preferably directly above the folding axis.
  • the weight of the holder folding part which acts on the folding axis, leads to a particularly large lever action which places the main part in the upright position if, in a further embodiment according to the invention, the intermediate piece is connected to the latter in the region of the outer edge of the one holder part, namely the main part is.
  • both downward and horizontally directed forces are transferred to the holder with the wiping cover stretched over the handle. Trouble-free transmission of the forces pointing horizontally in any direction is possible if the intermediate piece is plate-shaped and stiff in the horizontal directions.
  • cleaning devices without this feature are also within the scope of the invention. With these devices, however, only the forces pointing in certain horizontal directions can be transferred from the handle to the holder, unless other measures are provided.
  • the intermediate piece itself can be in different shapes and consist of different materials as long as it can be bent or pivoted parallel or obliquely to the folding axis of the holder.
  • the intermediate piece is preferably designed as an elastic flap and in particular made of flexible plastic or spring steel.
  • the hinge of the handle is attached to this tab.
  • Such an elastic tab offers cost advantages in terms of production and material.
  • a particularly good bendability of the intermediate piece is achieved if it is designed as an articulated hinge on which the articulation of the stem is attached.
  • the folding holder is plate-shaped and has a folding axis running parallel to the longitudinal axis.
  • the invention also includes holders made of wire frames or other constructions as well as holders with a different orientation of the folding axis.
  • the holder 1 shown in top view in FIG. 1 consists of two parts 2, 3 which can be rotated downward about their common folding axis 6 in the direction of the paper plane.
  • the axis of rotation 5 for a stem sleeve 10 is provided at a distance A from the folding axis 6 on part 2, the main part of the holder 1. Both axes, the folding axis 6 and the axis of rotation 5 for the stem sleeve 10, run parallel to one another and in the longitudinal direction of the elongated holder 1.
  • the pivot axis 5 is in the present case part of a cardan joint 4 for the stem sleeve 10.
  • FIG. 3 shows the beveled long sides 11, 12 and the narrow area of the main part 2 and the following wide area of part 3 with the folding axis 6.
  • the beveled contact surfaces 14 of the parts 2 and 3 can also be clearly seen.
  • FIG. 4 shows the beveled, long sides 11 and 12 and the wide area of the main part 2 with the pivot axis 5 and the folding axis 6 and the narrow area of the part 3.
  • the contact surfaces 14a are also beveled here, but in the opposite direction to the contact surfaces 14 in Figure 3.
  • the main part 2 of the holder has a significantly lower weight than the other part 3.
  • the holder When lifting the device handle 7 inserted into the handle sleeve 10, the holder is prevented from collapsing about its folding axis 6 in that the relatively heavy holder part 3 exerts a sufficiently large force on the folding axis 6 to move the relatively light holder part 2 with its long side 11 to press up.
  • the necessary force depends essentially on the distance A of the folding axis 6 from the handle attachment point and on the weight distribution within the folding holder main part 3.
  • the two-part holder surface When lifting the handle 7, the two-part holder surface therefore remains almost closed and in one plane. It forms one in this embodiment An angle of approximately 70 ° to 90 ° to the floor surface 13, as is shown schematically in FIG. 5.
  • the mop cover with its pocket 8 attached to the long side hangs on the edge 11 of the main part 2 of the holder 1.
  • the edge 12 also remains in its pocket, since the entire holder 1 lies almost in one plane and is not substantially folded down .
  • no locking is required for the two parts 2 and 3 in order to prevent the mop cover 9 from slipping off the holder 1.
  • the cleaning device according to the invention is used in the following way.
  • the flat mop cover with its insert pockets 8 attached to the long sides lies flat on the floor, the insert pockets pointing upwards.
  • the holder 1 is pulled upwards with the handle 7, so that it hangs obliquely downwards and forms an angle of approximately 70 ° to 90 ° to the floor surface 13 (FIG. 5).
  • the folding part 3, which is not directly attached to the stem 7 or the stem sleeve 10, points downwards, the main part 2 upwards. In this orientation, the long edge 12 of the holder part 3 is inserted into an insertion pocket 8 of the cover. After the handle 7 has been lowered, the holder part 2 rests on the other insertion pocket 8. To fold down the two holder parts 1, 2 in the direction of the floor 13, the part 2 of the holder is weighted with one foot and the handle 7 is pulled upwards.
  • the holder 1, which is now folded down about the folding axis 6, is shortened in its transverse direction and can be pushed into the second insertion pocket 8 by depressing the handle 7.
  • the holder 1 thus stretched and lying in one plane remains almost in the extended position when the device handle 7 is raised again, so that the mop cover does not slip off the holder.
  • the mop cover is removed from the folding holder 1 in the reverse order.
  • Figures 6 to 9 show a second and a third embodiment of the folding holder according to the invention.
  • the gimbal joint 4 is not directly on the upper side of the main part 2, but rather on one that serves as an intermediate piece elastic tab 15 attached.
  • the tab 15 is fastened to the upper side of the main part 2 of the folding holder via point connections 16.
  • the tab 15 is replaced by an articulated hinge 17 with an articulation 18.
  • the essentially rectangular, plastic holder has tapered holder edges.
  • the folding holder main part 2 and the folding holder folding part 3 are connected to one another via a folding axis 6.
  • the already mentioned elastic tab 15, which consists of spring steel or flexible plastic or the like, is attached to the top of the folding holder main part 2.
  • What is essential in this intermediate piece is the flexibility perpendicular to the upper side of the main part 2 and the stiffness in the horizontal directions, that is to say in the plane of the upper side of the main part 2.
  • the tab 15 is preferably fastened to the main edge 2 of the main holder 2 at a distance of approximately 1 cm. In this example, there is a point connection 16.
  • the cardan joint 4 On the end of the elastic tab opposite the punctiform connection 16, the cardan joint 4 is attached with a stem sleeve. In the state of use, that is to say during the wiping process, the cardanic joint is preferably located immediately above the folding axis 6.
  • the total width of the elastic tab 15 can also be the same as that of the folding holder main part 2.
  • the term "width” here means the extension of the tab from the fastening location 16 in the direction of the cardan joint 4.
  • the stiffness in the horizontal direction enables the holder to be easily moved in the forward, backward and sideways as well as oblique direction.
  • the holder To open and remove the cover, the holder lies flat on the floor. With one foot, the outer edge of the folding part 3 is held near the ground and the handle 7 is pulled up. This situation is shown schematically in Figure 7b.
  • the holder 1 folds downwards and the outer edges of the holder shortened in this way slide out of the longitudinal pockets 8 of the mop cover 9.
  • the mop cover is put on the holder in reverse order.
  • the long side 11 of the main folding holder part 2 is pushed into one of the two long pockets 8 of the cover 9.
  • the longitudinal side 12 of the folding holder folding part can also be inserted into one of the two pockets of the cover 9 first.
  • the longitudinal side 12 lies on the floor, so that the folding axis 6 is partially relieved of the weight of the folding part 3.
  • the main part 2 moves about the folding axis 6, so that the holder 1 is shortened in width and in this way allows the other longitudinal side 11 to be inserted into the second longitudinal pocket 8 of the cover 9.
