Abstract

The invention relates to a mop, which may be designed in particular as a floor mop and has a handle and a pressing device, which can be moved along the handle, for pressing two pivotably mounted mop plate segments against each other. The known mops have the disadvantage that the folded-together mop plate segments must be inserted into the pressing device or that the mop plate cannot be rotatably designed. The invention avoids this by the pressing device being mounted rotatably in relation to the handle.

WIPER

Technical area

The invention relates to a wiper, which is designed in particular as a floor wiper. The wiper has a handle, a wiper plate disposed at one end of the handle, the two wipers extending outwardly from the handle and pivotable toward each other downwardly

Wiper plate wings, and one along the stem between an upper position of use and a lower Auspressstellung

displaceable pressing device for pressing against each other of the two downwardly pivoted squeegee blades in the Auspressstellung, wherein the pressing device in the Auspressstellung the

Mop plate wings pressed against each other and releases the mop plate wings in a wiping position.

State of the art

From EP 1208788 A wet mop with two pressure arms for pressing against each other of hinged mounted squeegee blades are known. The squeegee blades are part of a mop head, which is attached via a universal joint pivoting freely at the end of a stem. The pressure arms are attached to a displaceable along the stem displaceable sleeve. To allow a reliable squeezing in any position of the stem are on the

Wischplattenflügeln and / or provided on the pressure arms guide means for defined folding.

The known wet mop has the disadvantage that it constructive

is complex and in particular that the leadership institutions must be carefully coordinated to ensure the folding function. Therefore, for example, replacing the entire mop head in practice is not feasible or very expensive.

For simpler wipers, the mop plate is again not rotatably mounted. However, this complicates the wiping process.

Presentation of the invention It is the object of the present invention to provide a wiper with mutually pressable squeegee blades, which are independent of the design of the folding squeegee blades or the mop head on which the squeegee blades are arranged a reliable squeezing from any initial position of the stem allows.

The object is achieved by a wiper, the thereby

is characterized in that the pressing device is designed such that it at least during a portion of the displacement from the wiping position in the Auspressstellung the mop plate via a

Forced guidance is forcibly rotated for threading in the pressing device by a certain angle. The angle is preferably less than 90 °, more preferably between 30 ° and 60 °, so that threading is also possible automatically in angular frames or cages of a pressing device.

The wiper according to the invention has the advantage that the pressing device captures the wiping plates at the initiation of Auspressvorganges by their rotational movement regardless of the angular position of the mop plate wing to the stem and entrains in the necessary position for pressing out.

In particular, in a particular embodiment of the

wiper according to the invention, in which the squeegee blades,

For example, as part of a mop head directly or indirectly gimbal and / or universal joint are connected to the stem there is a risk that the pressing device when initiating the Auspressvorganges at an oblique angle to the hinged to the stem tailed mop head or hits, so that it without the inventive Rotary movement of the pressing device could come to jamming.

In a preferred embodiment of the invention it is provided that the pressing device is rotatably mounted about the stem center axis. However, it is also possible that the pressing device is rotatably mounted about an axis parallel to the stem center axis. Distance may be provided according to the invention that the pressing device to a for Displacement direction parallel axis is rotatably mounted.

The wiper according to the invention is designed such that the

Pressing device optionally in a Auspressstellung in which it presses the mop plate wings against each other, or a wiping position in which it releases the mop plate wings, can be transferred. This version is particularly easy to handle due to the positive guidance for rotating the pressing device, which is designed in such a way that the wiping plate is rotated when transferring from the wiping position to the expressing position.

For example, the positive guide may have a guide groove, in which engages a guide pin. In particular, the guide groove can advantageously be helically wound and / or curved.

The wiper according to the invention can with different

Press devices are realized. For example, the

Pressing device having press arms with flexible free ends or press arms with rigid free ends.

In contrast to the wipers known from the prior art, the wiper according to the invention instead of press arms (or in addition to press arms) may also have a closed frame, which is even with filigree and compact design in a position to greater forces on the mop plate wings transferred, as freely ending press forks.

In particular, it can be provided according to the invention that the mop plate wings are embraced in the Auspressstellung of the frame.

This filigree frame has the further advantage that only a little

Dirty water comes into contact with the frame and hardly

Inaccessible areas are present, which are dried by

Dirty water could be contaminated.

In a particularly good expressive embodiment of

The wiper according to the invention is provided that the enclosed by frame inner surface approximately the cross-sectional area of the

against each pressed squeegee blade corresponds; Preferably, the distance of the opposing, acting on the upper sides of the mop plate wings frame sides is smaller than the thickness of the Wiper plate wings together with the double-laid, non-pressed mop cover. The smaller the distance is selected, the more the applied pressing force

The frame may be formed, for example, quadrangular, this

In particular, when the wiping surface facing away from the upper sides of the mop plate wings are flat. However, it is also possible, for example, to give the squeegee blades particular stability, this curved or rounded form, so that it is advantageous in these embodiments, the frame also correspondingly curved or round. In any case, it is advantageous if the frame in the Auspressstellung conforms to the tops of the mop plate wings.

To achieve a particularly good Auspressergebnis, may alternatively or additionally also be provided that the frame has inwardly directed pressing projections and / or press noses and / or pressing surfaces.

In an advantageous embodiment, the inner surface of the

Frame includes, arranged perpendicular to the longitudinal direction of the style.

A particularly well-cleaning embodiment of the wiper according to the invention is constructed such that on the frame, at least one - preferably two - scrapers are arranged such that the emerging during Auspressvorgang between the squeegee blades dirt and / or the moisture exiting there is stripped. The scraper may be formed for example as a rubber lip. In addition, the scraper may be arranged so that it

Squeezing process on the side edges of the squeegee blades and / or the side edges of a mop cover scrapes along.

In an advantageous embodiment of the wiper according to the invention it is provided that the pressing device has a sleeve displaceable along the handle. In addition, it can be provided that the frame and / or the pressing arms are attached directly or indirectly to the sleeve. For example, it can also be provided that the frame is fastened to the sleeve with a connecting device. This may, for example, have struts, which in itself must exert no pressing pressure on the mop plate wings. Alternatively, the connecting device may also be designed box-shaped.

In a particularly simple to manufacture and robust embodiment, a box is provided, the lower edge portion forms the frame, the middle part forms the connecting device and the upper part of an opening - preferably a bore - through which the stem extends. This embodiment has the advantage that almost the entire squeezing device can be formed as a one-piece, open-bottom box with a hole arranged above.

Very easy to use and comfortable is a special

Embodiment of the wiper according to the invention, wherein it is provided that the frame is rotatably mounted about the stem center axis.

In particular, it can be provided that the frame is directly or indirectly constrained in such a way that it moves when transferring from the

Wiping position turns into the Auspressstellung. Instead of the stem central axis, the frame can also rotate about an axis parallel thereto, for example about an axis perpendicular to its inner surface. Due to the rotational movement is a jamming, regardless of the position of the mop head relative to the stem at the initiation of

Auspressvorganges, effectively and reliably avoided.

A positively driven rotation of the frame, for example

be achieved in that the sleeve has a curved - in particular helically curved - guide groove, in which engages a stem arranged on the guide mandrel. Alternatively, conversely, it can also be provided that the handle has a curved - in particular

helically curved - has guide groove, in which a sleeve arranged on the guide pin engages.

Particularly user-friendly is an embodiment of the

Wiper according to the invention, in which a handle is provided which can be operated independently of a rotational movement of the pressing device and / or the frame and / or the sleeve and / or the connecting device. For example, such a handle relative to Press device and / or rotatably mounted relative to the sleeve.

In particular, it can be provided that the handle is rotatably mounted about the same axis, as the pressing device and / or the

Frame and / or the sleeve. In particular, it can be provided that the handle is arranged coaxially to the sleeve. For example, the handle may be tubular.
