FLAT MOP
Description Technical Field The invention relates to a flat mop including a mop plate having a cleaning side over which a mop cover can be stretched, whereby the mop plate has two folding mop plate parts lying adjacent to one another.

Background Art Such flat mops are generally known. The mop plate is connectable with a handle which is most of the time jointedly connected to the upper side of the mop plate. Mop covers are stretched over the mop plate for wet cleaning, which can be soaked with a cleaning liquid. The mop covers can be connected to the mop plates by way of pockets or positive or non-positive fastening elements. The mop plate is made of injection molded plastic and has a mostly rectangular shape. The upper side of the mop plate is constructed smoothly and the cleaning side has a ribbed structure, whereby the ribs are mostly oriented in elongated rectangles relative to one another. The ribbed structure results in material economy and at the same time provides the mop plate with high rigidity.

Description of the Invention It is an object of the invention to provide a flat mop which provides an improved cleaning performance for hard to reach locations.
This object is achieved with the features of claim 1. Preferred embodiments are dealt with in the dependent claims.
This object is achieved by constructing the mop plate in a trapezoidal shape.
The trapezoidal shape results in two blunt edges which are associated with the shorter longitudinal edge and two pointed edges which are associated with the longer longitudinal edge. Hard to reach corner regions of the floor to be cleaned can be reached and cleaned in an advantageous manner by way of the pointed edges. It is conceivable to arrange the ribs on the underside of the flat mop in a honeycomb pattern. The ribs are thereby, contrary to the known ribbed structures, not continuous but form segments of a comb. This results in spaces which are defined by the length of the segments. These combs form the cleaning side of the mop plate. A mop plate of such construction has a high bending stiffness and at r r the same time has an evenly distributed contact with the mop cover, because of the evenly distributed ribs, This results in an even pressing of the mop cover onto the floor to be cleaned and thereby an evened out cleaning result. In a preferred embodiment, the length of the ribs is selected such that five combs can be positioned offset to one another across the width of the mop plate. A mop plate with a cleaning side consisting of a honeycomb shaped ribbed structure is especially easily and cost efficiently manufactured with an injection molding process. The ribs can thereby be constructed in such a way that they thicken from the cleaning side in a direction towards the upper side of the mop plate. The mop plate is thereby especially easily removed from the injection mold.
The corners of the mop plate associated with the longer longitudinal edge can be bent up. The corners thus have the shape of winglets. Pocket shaped mop covers are mostly stretched over the mop plate. To mount the mop cover, the mop plate parts are folded towards one another and the free ends of the mop plate parts are inserted into the pockets of the mop cover. The mop plate parts are thereafter straightened and locked. By folding the mop plate parts, their free ends are directed almost vertically downward, which because of the high normal force complicates the sliding of the free ends on the mop cover towards the pockets. Because of the winglets formed the edges, the free ends are no longer directed virtually vertically downward when the mop cover is folded together, but point at least partially in the direction of the pockets when the mop plate parts are folded together.
This significantly improves the sliding of the mop plate parts on the mop cover towards the pockets and thereby the mounting of the mop cover onto the mop plate.
A retaining arrangement can be provided on the cleaning side. The wet cleaning, depending on the floor to be cleaned, can be associated with high frictional forces, whereby the mop cover can be displaced, which worsens the cleaning results. A
displacement of the mop cover is prevented by the retaining arrangement which can have a non-positive or positive action principle. This preferred embodiment is also conceivable in other embodiments of a mop plate which go beyond the present inventive embodiment.
The retaining arrangement can have a force-fit (non-positive) action principle.
Non-positive retaining arrangements can be especially easily realized namely by materials which have a high frictional value. The retaining arrangement can thereby be in the same plane as the ribs or protrude therefrom. It is also possible to cover the ribs with an elastomer which has a high frictional value. This results in a flat T-shaped retaining = .
arrangement. In other embodiments, multiple pin-like projections can be formed on the cleaning side which at their free ends have a material with high frictional value. It is advantageous in that embodiment that the retaining arrangement on the one hand prevents a displacement of the mop cover, but on the other hand also prevents sliding of the mop plate of the cleaning apparatus when it is placed on the floor without mop cover.
The retaining arrangement can be formed by elastomeric bodies. Elastomeric bodies, for example rubber knobs, are easily and cost efficiently manufactured. They can be fastened to the mop plate by simple means, for example gluing.
The mop plate parts can be pivotally connected with one another by a locking element, whereby the locking element is provided with a spring body so that the locking of the mop plate parts occurs against the force of the spring body. This provides the advantage that the mop plate parts during the unlocking fold apart far enough that they can no longer lock on their own. This facilitates the handling of the mop plate.
The spring body can be formed by an elastomeric body. Spring bodies formed of elastomeric bodies are especially robust, have a long service life and are cost efficient.
The side of the mop plate directed away from the cleaning side can have a waved structure. The stiffness of the mop plate is increased by this waved structure in the particularly loaded regions. In the central region where the handle is connected to the mop plate, a wave trough is provided, whereby the handle connection and thereby the center of mass of the mop plate is located especially low.
The mop plate can be divided in such a way that mop plates of essentially equal size result. The mop plate parts can thereby be jointed to an intermediate piece. With such an embodiment, the mop plate parts can be folded mirror symmetrically and in the folded condition hang downwards to the same degree from the intermediate part or the joint connection. This facilitates the mounting of the mop cover, since the corners of the mop plate associated with the longer longitudinal side simultaneously come into contact with the pockets of the mop cover. This embodiment is especially advantageous in connection with the above described curved corners associated with the longer longitudinal side of the mop plate.

r c Brief Description of the Drawings Several preferred embodiments of the flat mop in accordance with the invention are described in the following by way of the figures. They respectively schematically illustrate the following:
Fig. 1 shows the mop plate in accordance with the invention from below;
Fig. 2 shows the mop plate in perspective view;
Fig. 3 illustrates a mop plate part with locking element and spring body; and Fig. 4 illustrates a mop plate with mirror symmetrically foldable mop plate parts.
Embodiment of the Invention Figure 1 shows a mop plate 2, consisting of two foldably associated mop plate parts 5, 6, and having a cleaning side 3 which is formed by ribs 7. The ribs 7 are oriented to one another in a honeycomb shape. A mop cover with pockets (not illustrated) can be stretched over the mop plate 2, whereby the mop cover covers the cleaning side 3 and thereby comes into contact with the ribs 7. The mop plate 2 is in the shape of a trapezoid.
A retaining arrangement 11 is positioned on the cleaning side 3, which consists of four elastomeric bodies made of rubber, whereby the retaining arrangement 11 has a non-positive (force-fit) action principle. The mop plate 2 consists of plastic and is manufactured by injection molding.
Figure 2 shows the mop plate 1 according to Figure 1 in perspective illustration. It is shown that the corners 9, 10 associated with the longer longitudinal side 8 of the mop plate 2 are curved and thereby have the shape of winglets. Furthermore, the side 14 of the mop plate 2 directed away from the cleaning side 3 is constructed to achieve a wave structure. The wave crests are thereby respectively associated with a middle of each mop plate part 5, 6 and a wave trough is associated with the middle of the mop plate 2 and the corners 9, 10. A receptacle 15 is further provided at the center of the mop plate 2 by which the mop plate 2 can be jointedly connected with a handle. Both mop plate parts 5, 6 are hingedly connected with one another by a locking element 12 so that the mop plate parts 5, 6 are foldable relative to one another. A locking element 12 is tiltingly mounted on one mop plate part 6 and overlaps a portion of the other mop plate part 5 to thereby prevent a self-acting folding of the mop plate parts 5, 6. The portion is released by tilting of the locking element 12 to enable a folding of the mop plate parts 5, 6.

r .
Figure 3 shows in detail a mop plate part 6 according to Figure 1 or 2. It is illustrated that a spring body 13 consisting of an elastomeric body is associated with the locking elements 12 in such a way that the locking of the mop plate parts 5, 6 occurs against the force of the spring body 13. Two spring bodies 13 are thereby provided in the 5 region of the locking element 12 on the mop plate part 6. The spring bodies 13, consist of semi-spherical rubber bodies. When the mop plate parts 5, 6 are locked by the locking element 12, the spring bodies 13 located on the mop plate part 6 are compressed and exert a force onto the other mop plate part 5. A flat mop according to claims 1 to 6, characterized in that the mop plate parts 5, 6 are hingedly connected by a locking element 12, whereby the locking element 12 is associated with a spring body 13 is such a way that the locking of the mop plate parts 5, 6 occurs against the force of the spring body 13.
Figure 4 shows the mop plate 2 of a flat mop 1. The mop plate 2 consists of two mop plate parts 5, 6 which essentially have the same size with respect to their cleaning side 3. The mop plate parts 5, 6 are jointedly connected with an intermediate part 16 so that the mop plate parts 5, 6 can be mirror symmetrically folded. A receptacle for a handle 15 is jointedly centrally connected with the intermediate part 16. The cleaning side 3 of the mop plates 5, 6 is formed with ribs 7, whereby the ribs are oriented in a honeycomb shape. Alternatively shaped cleaning sides 3 are also conceivable within the embodiment according to Figure 4, for example flat surfaces. A mop cover with pockets (not illustrated) can be stretched over the mop plate 2, whereby the mop cover covers the cleaning site 3 and thereby comes into contact with the ribs 7. The mop plate 2 has the shape of a trapezoid, whereby the corners 9, 10 associated with the longer longitudinal side 8 of the mop plate 2 are bent up and therefore form winglets.
Furthermore, the side 14 directed away from the cleaning side 3 is constructed to have a waved structure. The wave crests are thereby respectively positioned in the center of the mop plate part 5, 6 and a wave trough is associated with the center of the mop plate 2 and the corners 9, 10. A
retaining arrangement 11 is positioned on the cleaning side 3, which consists of four elastomeric bodies made of rubber, whereby the retaining arrangement has a force-fit (non-positive) action principle. A locking element 12 is tiltedly mounted on one mop plate part 6 and overlaps a portion of the other mop plate part 5 and thereby prevents a self-acting pivoting of the mop plate parts 5, 6. This portion in turn overlaps in the closed condition of the mop plate 2 also the intermediate part 16. This portion is released by tilting of the locking element 12, thereby enabling a pivoting of the mop plate parts 5, 6 relative to the intermediate part 16. The mop plate 2 is made of plastic and manufactured by an injection molding process.
