Description

Field of the invention

The invention relates to a squeezing device for squeezing wet mop covers, especially mops, a set consisting of such a squeezing device and also an associated container on which the squeezing is placed as well as a mop holder for use in such a set.

State of the art

Conventional mop presses are known on the market and serve to wipe mops after washing in a cleaning liquid or after the first wetting with cleaning fluid from excess cleaning fluid. For this purpose, the mop cover is pressed by applying pressure. Conventional mop presses often use roller assemblies between which the mop cover is made and wrung out due to the pressure exerted by the rollers. Also, squeezing devices are known on the market to wring a wiper head mounted on a handle to pick up liquid. In this case, an adapted in the form of the wiper head, downwardly tapering container provided, which has openings in its walls, wherein the upper edge of the container at the upper edge of a cleaning bucket is fastened. This is achieved by means of brackets that overlap the upper edge of a bucket. This device is only suitable for wringing or pressing special mop heads, wherein the mop head must be pressed by manual guidance of the stem into the container. The drainage of the mop cover thus depends decisively on the force applied by a cleaning person.

Presentation of the invention

The present invention has for its object to provide a squeezing device for squeezing wet mop covers, which allows for simple and convenient handling even with little effort an effective squeezing of mop covers, especially mop.

This object is achieved by a squeezing device with the features of claim 1. Preferred embodiments follow from the remaining claims.

The extrusion device according to the invention for pressing wet mop covers, in particular mops, has a lower part which can be placed on the edge of a container for holding cleaning liquid and furthermore comprises a press basket with openings for cleaning liquid, a press die which can be introduced into the press basket, and a user-operable one Actuation mechanism for the punch. The actuating mechanism has a hand lever which is pivotable relative to the lower part about a first pivot axis near the end of the hand lever opposite to a grip portion. In this case, the press ram is articulated on a first pivot axis substantially parallel to the second pivot axis. By the second Pivot axis is close to the first pivot axis between the first pivot axis and handle portion, a lever mechanism is created, which allows a cleaning person without having to wet his hands to be able to effectively squeeze a wet mop cover with little effort. The described extrusion device allows that when transferring the hand lever from an open position into a closed position of the articulated mounted on the second pivot axis press ram passes into the press basket and acts on a mop cover inserted there.

In such a squeezing device, the lower part is thus placed with the hand lever hinged thereto on the upper edge of the container for receiving cleaning liquid. After opening the hand lever, ie the pivoting of the hand lever, the press die leaves the press basket, so that a wet mop cover to be squeezed can be inserted into the press basket. By the hand lever is transferred to the closed position and is pivoted back under, the press stamp enters the press basket and acts on the therein wet mop cover. Depending on the geometry of the press ram in relation to the press basket and the volume of the wet mop cover to be pressed out, a predetermined proportion of the cleaning liquid is pressed out of the mop cover and can flow back through openings in the press basket into the container for receiving cleaning liquid. Due to the above-mentioned lever effect by the relative position of the substantially mutually parallel first and second pivot axis relative to the handle portion, considerable pressing forces can be transferred to the wet mop cover even at low power, so that an effective squeezing the mop covers even less strong people can be carried out.

Preferably, the press basket has a flat bottom in which passages for liquid are located.

Furthermore, it is preferred that the press basket has substantially planar, preferably conically tapering side walls. If the press basket to the plane of the bottom slightly conically towards the basket bottom has converging side walls, this can be done by the press ram when opening and closing the actuating mechanism. In addition, the kinematics of the articulated mounted on the hand lever press ram is taken into account. Finally, this measure can also provide advantages in a demolding of the press cage from an extrusion device, if the press basket is extruded from plastic.

Preferably, the squeezing device further comprises passage openings for liquid in at least one side wall of the press basket. By also in the side walls of the press basket, at least in the area adjacent the basket bottom openings for the escape of unwanted cleaning liquid are present, a wet mop cover can be pressed out more uniformly and faster. Such openings or passages for liquid can be in the form of vertical, i. be configured substantially perpendicular to the basket bottom arranged water drainage slots.

According to a preferred embodiment, the pressing punch has a pressing head with a lower-side pressing surface and an upper side. In this case, preferably, the pressing surface may be concavely curved and shaped, for example, partially cylindrical. It has been found in practice that due to this particular embodiment, the Auspressergebnis can be substantially improved over a flat pressing head. Such shaping can also have manufacturing advantages by the pressing surface in the form of a curved, rectangular plate, whereby the pressing surface can be produced at low cost of materials.

Preferably, the pressing head has passage openings for liquid. This measure, which promotes the escape of unwanted cleaning liquid from the mop cover during the pressing process, serves to dewater the mop cover as evenly as possible, not only in the bottom of the press basket passage openings are provided for liquid, but also the escape of liquid on the opposite side a mop cover located in the squeezing device is possible.

Preferably, the pressing head on the upper side on reinforcing ribs, which preferably extend in the direction of curvature. The provision of reinforcing ribs increases the stability of the pressing head and the arrangement of the reinforcing ribs in the direction of curvature serves not to hinder the drainage of cleaning liquid, but to channel in the direction of the side walls of the press basket.

A further improvement of the Auspressergebnisses can be achieved if the pressing surface is surface-structured, preferably having ribs which extend parallel to the second pivot axis.

It has proved to be particularly advantageous if the distance between the grip section on the hand lever and the second pivot axis corresponds approximately to twice to five times the distance between the second pivot axis and the first pivot axis. Of course, other gear ratios than the resulting gear ratio between 2: 1 and 5: 1 are possible, but you only get a favorable power transmission ratio when the distance of the second pivot axis of the first pivot axis is less than that Distance of the second pivot axis of the handle serving the operating portion.

The above-described squeezing device for squeezing wet mop covers is preferably provided in a set consisting of the squeezing device and an associated container, on which the squeezing device is placed. The provision of an associated container has the advantage that the squeezing device and the container can be coordinated so that a secure stand is ensured and the squeezing so largely rests on the container that even with large force, the resulting forces of the lower part of the squeezing can be safely introduced into the container walls.

If the set consisting of squeezing device and container stands on a flat surface, it has proved to be advantageous to design the lower part so that it has an inclined surface in the direction of the press basket between the first pivot axis and the press basket. By this measure can prevent that when opening the hand lever and the pivoting out of the press ram from the press basket cleaning liquid can run next to the container. Cleaning liquid dripping from the press die strikes the bevelled surface and is discharged in the direction of the press basket.

According to a preferred embodiment, there is also a pouring opening between the lower part of the squeezing device and the container in the region of the first pivot axis. For this purpose, the lower part may be bevelled on its underside in the region of the end at the first pivot axis towards the end upwards. When pouring cleaning liquid from the container thus the operator can use the free ends of the lower part and hand lever together with a provided on the container strap handle on the Hold container edge, while the cleaning liquid can flow out of the container in the region of the first pivot axis with attached squeezing.

According to a preferred embodiment, the hand lever is dimensioned and arranged so that it does not extend beyond the dimensions of the container for receiving liquid in the closed position with the inserted into the press basket punch. In this way, on the one hand limits the squeezing on the space required by the container. On the other hand, the hand lever with low center of gravity can safely and flatly rest on the edge of the container without reaching beyond its circumference. Finally, this measure prevents the container from tipping when pressure is applied to the hand lever during pressing. In general, however, it is advantageous if in the closed position of the handle shell has no projecting hand lever or other parts, which in handling the container with the cleaning liquid, e.g. when pouring or when placing in confined spaces, could be a hindrance.

Preferably, the press die and the press basket are shaped so that when an inserted into the press basket punch for pressing a mop cover, an associated mop holder between a side wall of the press basket and the press die can be located. Preferably, this is realized in the form of a correspondingly shaped and dimensioned bulge in a side wall of the press basket. In this way, the mop cover must not be removed from the mop holder while the mop cover is pressed out.

The set according to the invention consisting of the squeezing device and the associated container as described above is preferably used with a mop which consists of two fixing wings that can be pivoted relative to one another and can be locked in an operating position, which are insertable in receiving pockets of an associated mop cover. By providing the two relatively pivotable mounting wings, the mop holder can be brought into a position in which the mop cover is inserted into the press basket, without the mop cover must be completely detached from the mop holder.

In this context, it has proved to be advantageous if the mop holder comprises a slot opening on at least one of the two attachment wings for receiving a fastening loop provided on the mop cover. In this slot opening the mop located fastening loop is retracted to provide a firm connection of the mop cover and mop holder, even if one opens the mop holder, that brings from the operating position to a second position in which the mounting wings are pivoted toward each other. In this way, the user of the mop holder including mop dip the handle of the mop holder in the cleaning liquid after dirt has adhered to the wiping surface of the mop cover as part of a cleaning process. In this way, the mop cover can be washed out in the cleaning liquid. Subsequently, the mop holder is inserted with the attached mop cover so in the press basket, that the mop cover is in the region of the bottom of the press basket, while the mop holder is located in a bulge in a side wall of the press basket. Subsequently, the hand lever can be gripped on the handle portion and operated with one hand. Upon actuation of the hand lever of the press ram is inserted into the press basket and exerts pressure on the mop cover, so that excess cleaning fluid is wrung out of the mop cover. This is done without the user's hand coming into contact with dirt or moisture, thereby allowing the user to work comfortably.

Since conventional mop systems include a mop cover, which is equipped on the back with two pockets, in which the mounting wings of the mop holder can be inserted, in conventional mop the cleaning process can be performed only by adding a hand. With the attachment loop, however, the mop cover can be fixed to the mop holder during the cleaning process, so that no additional holding by hand is required.

By actuating a pedal on the mop holder, for example, the locking of the fastening wings in the operating position can be solved. The mop holder opens, whereupon the mop cover only hangs on the mop holder with the fastening loop fastened in the slot opening. This position also facilitates the insertion of the mop holder with the mop cover located thereon in the press basket of the squeezing device, because by inserting the handle of the mop holder with the mop located thereon automatically the starting position for the subsequent process of squeezing the mop cover is created. Also, the subsequent operation of the hand lever for pressing the mop cover can be carried out without having to take the mop cover itself in the hand. After the subsequent opening of the press basket and removing the press ram, the handle of the mop holder can be removed with the mop cover located thereon. The mop holder is returned to the operating position and locked the mounting wings in this position. During this process, the two attachment wings of the holder are reinserted into the pockets located on the mop cover.

Ways to carry out the invention

In the following figures, the same elements are designated by the same reference numerals.

In Fig. 1 an extrusion device 10 according to the invention is shown, which is placed on an associated container 12 for receiving cleaning liquid. As from the illustration in Fig. 1 it can be seen, the squeezing device 10 has a lower part 14 which has a peripheral edge for placement on the container 12, an integrally formed with the lower part of the press basket 16, a ram 18 and a hand lever 20. The ram 18 is designed to be in relation to its shape substantially conforms to the shape of the press basket 16. The hand lever 20 has a handle portion 22 and is dimensioned so that it is in the in Fig. 1 illustrated closed position of the existing lever and press ram actuating mechanism does not extend beyond the outer edge of the container 12 addition. Both the container 12 and the squeezing device can essentially be made of plastic, that is, with the exception of the later-described pivot axes.

The Fig. 2 shows the set consisting of squeezing device 10 and container 12 in the open position of the actuating mechanism. It can be seen that the hand lever 20 is rotatable about a first pivot axis 24, which in the illustration in Fig. 5 is more apparent. The pressing ram 18 is rotatably mounted on the hand lever about the second pivot axis 26 and has a pressing head 28 which has a pressing surface 30 with a plurality of passage openings 32 for cleaning liquid. The pressing surface is concave and preferably part-cylindrical. On the opposite side of the pressing surface, ie the top of the press ram ribs 34 are provided for reinforcement, which reinforce the ram. The ribs 34 are hinted at Fig. 2 but better in Fig. 1 to recognize.

The press basket 16 is provided with a substantially flat bottom surface 38, in which there are a plurality of passage openings 40 for cleaning fluid. The adjacent side walls 42 of the press basket 16 may be arranged perpendicular to the bottom surface 38 but also inclined to the vertical and open to the top of the squeezing out. If the press ram is provided with a shape substantially corresponding to the inner contour of the press basket and an articulation arm 44 between the press head 28 and the second pivot axis 26, a reliable guidance of the press ram can be ensured in the press basket with sufficient play.

To improve the removal of excess cleaning fluid, the side walls 42 are provided with slot-shaped passage openings 46, which are preferably arranged in those areas of the side walls 42 close to the bottom surface 38.

If the hand lever 20 of the in Fig. 2 shown position towards the in Fig. 1 actuated position shown, the press ram 18 enters the press basket 16 and wringing out a arranged on the bottom of the press cage 16 mop cover. In this case, a high force between the punch and press basket is generated by the leverage of the hand lever. The leverage effect is that the distance between the handle portion 22 of the hand lever 20 and the second pivot axis 26 is significantly greater than the distance between the first pivot axis and the second pivot axis.

Fig. 3 shows a mop holder 50 for use in a squeezing device Fig. 1 or Fig. 2 , In addition to a gripping element 52, the mop holder has two fastening wings 54, 56 which, with the aid of a locking device 58 in the in Fig. 3 shown working position can be fixed. The end portions 60 of both fastening wings 54, 56 are designed to be able to engage in correspondingly shaped receiving pockets on the top of a mop cover.

The two mounting wings 54, 56 are pivotally arranged to each other and can after loosening the lock 58 in the in Fig. 4 shown position, which serves for cleaning and wringing out of an associated mop cover. The sequence of wringing out a mop cover 62 is shown in the sectional view in FIG characters 5 and 6 clear. After opening the mop holder in the in Fig. 4 shown position, the mop cover 62 depends on the two end portions 60 of the mop holder. For this purpose, at least one attachment wing of the mop holder is provided with a slot opening 64, which in the Figures 3 and 4 it can be seen and serves to receive a fastening loop on the mop cover, so that even in the open position of the mop holder 50, the mop cover 62 does not detach from this and remains connected without manual intervention of the user with the mop holder 50.

How out Fig. 5 it can be seen, the mop cover 62 is first introduced into the press basket 16. Subsequently, the user grasps the hand lever 20 and brings it from the in Fig. 5 shown position by a pivoting movement in the in Fig. 5 shown arrow A in the direction of the closed position. An intermediate position when pressing a mop cover is in Fig. 6 shown. The mop cover 62 is disposed in the press basket 16 and the press head 28 moves into the press basket 16 to compress the mop cover 62 therein. The two attachment wings 54, 56 of the mop holder 50 are located in a groove-shaped recess 66 in the side wall of the press basket 16, the best in the view in the Fig. 2 is recognizable. In this way, the mop cover can be pressed without this must be removed from the mop holder.

After the hand lever 20 from the in Fig. 6 shown position has been moved even further in the direction of arrow B and the mop cover 62 located in the press basket 16 has been sufficiently squeezed, the squeezing device 10 by pressing the hand lever in the opposite direction to the in Fig. 5 opened position again. The still open mop cover with the hanging, now optimal moisture possessing mop cover can then be removed and the mop holder 50 back into the in Fig. 3 shown operating position, wherein before the Locking in the operating position must be ensured that the end portions 60 of the mounting wings 54, 56 engage again in corresponding mounting pockets on the top of the mop cover.

In Fig. 6 Finally, it can still be seen that in the area of the first pivot axis 24 of the lower part of the extrusion device 10 has an inclined surface which has a slope in the direction of the press basket 16. This inclined surface has two functions. On the one hand, dripping cleaning liquid is supplied via the inclined surface 68 to the press basket and thus to the container 12, on the other hand, by this inclined surface a pouring opening between the container and the squeezing device in the region of the first pivot axis 24 is generated, which are used for pouring the cleaning liquid with attached squeezing can.

Due to the design of the squeezing device, but also the associated and tailored to the design of the squeezing out shape of the mop holder and the attachment of the mop cover it can all steps of cleaning, pressing the kick button to open the mop holder, cleaning the mop cover, squeezing the mop cover and then Restoring the working position of the mop holder are carried out with mop cover without the user to do this, the mop cover must handle. In this way, the entire process can be performed without the user getting wet or dirty hands.
