Description

Field of the invention

The invention relates to a device for squeezing liquid-absorbing wiping bodies with the features of the preamble of claim 1. Furthermore, the invention relates to a mop with such a device.

For wet or wet wiping of floor surfaces Mophalter be used on a mop cover is clamped. The mop cover must be washed regularly and pressed out before use so that it does not contain any excess liquid. In order to at least partially squeeze out the liquid contained in the mop cover, before a cleaning of a bottom surface is continued or started, a device for squeezing is used.

Such a device for squeezing liquid-absorbing wiping bodies serves to receive a mop cover introduced into it, which may either be provided separately or is mounted on a holder, and to apply force to squeeze the liquid out of this. A device for expressing liquid can be placed on or integrated in a bucket or a similar collecting vessel. On the one hand, the vessel serves to receive liquid that has been squeezed out, on the other hand, however, it can contain a cleaning liquid, into which the mop cover is dipped before being pressed out.

State of the art

In the art mop cover dispensing devices are known in the state clamped on a holder. In particular, such devices are used for substantially rectangular mop holders and covers.

A device with two pressing jaws, between which the tensioned on a mop holder mop cover is pressed, is known from the G 94 16 565. The device described therein comprises two pressing jaws, which are each mounted by four pins in grooves provided for this purpose on the bucket. In order to move the pressing jaws from an open to a closed position expressing the mop holder, supporting arms are provided on the pressing jaws perpendicular to the direction of movement of the mop holder, on which the mop holder presses during insertion in order to initiate the movement of the pressing jaws downwards and towards each other , In this device, the entire squeezing force must be generated by the cleaning force by a mechanical pressure force on the support elements.

To reduce the force required to squeeze out a mop holder with mop cover stretched on the mop holder, after the EP 1 138 246 B1 a press lever used, which is hingedly connected to a clamping device and with the clamping device closed by means of the lever action transmits a force on the pressing jaws and brings them into a closed position. However, the movement sequence for actuating the mop press is complex. First of all, the mop holder with the mop cover stretched down is guided vertically downwards, so that it is enclosed laterally by the first and second pressing jaws. If the mop holder with mop cover has been inserted deep enough, the pressing lever is first rotated in a first direction, whereby a clamping lever attached to the clamping lever can engage with locking lugs, which are provided on one of the two pressing jaws. Subsequently the lever is retracted while the clamping lever remains in engagement with the locking lugs and due to the articulated mounting of the pressing lever on the other pressing jaw, the pressing jaws are stretched toward one another, whereby the mop holder with clamped mop cover arranged between the pressing jaws is dehydrated. To open the squeezing the lever must first be moved back sufficiently far opposite the rotational movement during pressing until the clamping lever is no longer in engagement with the locking lugs and then pivoted back in the opposite direction until the squeezing in its open position and the mop holder can be removed again with the mop cover stretched out of the squeezing device.

The CH 173 044 A describes a pressable on a container press for pressing liquid with a solid pressing wall and a hingedly connected to this movable pressing wall. The press is operated by a hand lever, the depression of which reduces the distance between the fixed press wall and the movable press wall. The operating mechanism with the help of a toggle lever is designed so that the transmission ratio increases as the pressing space is reduced. The CH 173 044 A represents the closest prior art.

Presentation of the invention

The invention has for its object to design a compact device for pressing liquid absorbing wiping bodies, which can be actuated by means of a simple movement and can be kept with little effort in the closed extrusion position.

This object is achieved by a device for expressing liquid-absorbing wiping bodies having the features of claim 1. A mop press comprising a Device according to the invention is described by the features of claim 10.

The device for squeezing liquid-absorbing wiping bodies comprises a first, substantially plate-shaped pressing jaw, and a second, substantially plate-shaped pressing jaw, which are connected to each other in the region of their respective first end via a hinge. In operating position, the respective first end of the pressing jaws is below. The device further comprises a pressing lever which is connected to the second pressing jaw in the region of second end of the second pressing jaw, ie in the operating position in the upper region of the second pressing jaw, is connected via a first bearing articulated to the second pressing jaw. The device is characterized in that the first pressing jaw is arranged stationary relative to the device and the pressing lever comprises a toggle lever portion between the first bearing and a second bearing fixed to the pressing lever, wherein the second bearing a toggle element is attached, which is a rigid connection between the second bearing and a third bearing in the region of the second end of the first pressing jaw forms. The third bearing is thus arranged stationary relative to the first pressing jaw. Since the first pressing jaw is arranged stationary relative to the device, and the joint is stationary relative to the device.

The device according to the invention has a compact construction, since the first pressing jaw is not pivoted and therefore can be arranged substantially vertically in the device in the operating position. In this way, the device for pressing can be made very compact. Furthermore, the press lever with toggle mechanism according to the invention has several advantages. The provision of the pressing lever makes it possible to provide this with a sufficiently long lever arm, so that the device for pressing can be operated with little effort. The toggle mechanism consisting of the toggle lever portion and the toggle lever element provides a firm connection between the press jaw attached to the second press jaw and the first press jaw. Thus, it is not necessary first to establish a connection between the first press jaw and the second press jaw before the apparatus can be actuated. The device can be closed with a single lever movement and reopen a movement of the pressing lever in the reverse direction. The device is simple despite the use of a toggle mechanism, since the first portion of the toggle mechanism, the Knee lever portion, part of the pressing lever itself and thus in addition to the pressing lever only a single further element, namely the toggle element is provided, which establishes the connection between the second bearing on the pressing lever and the third bearing on the first pressing jaw.

According to a preferred embodiment of the invention, the pressing lever is movable between an open position with V-shaped first and second pressing jaws and a closed position with first and second pressing jaws arranged substantially parallel to one another. A V-shaped opening facilitates insertion of the mixed body to be squeezed out.

It is particularly preferable if, in the closed position, the toggle mechanism consisting of the toggle lever section and the toggle lever element is in the over-dead-center position. The closed position serves to drain a mop holder with mop cover stretched on. For this purpose, it is necessary to keep the device in the closed position for a few seconds, since the dewatering of the wiper body takes a few seconds. Experience has shown that cleaning personnel tends to move the pressing lever only in the closed position and then immediately open again. If the pressing lever is to be kept in a closed position over a certain period of time, this is associated with a permanent effort in conventional squeezing devices for the cleaning personnel, which can be avoided by the toggle mechanism according to the invention. When in the closed position the toggle mechanism has been moved beyond the dead center, the device locks itself in the closed position. No effort is required to hold the press in the closed position. After a few seconds, the lever can be opened again to the dead center with little effort and can be easily moved to the fully open position.

According to a preferred embodiment of the invention, the first bearing extends over the entire width of the second pressing jaw and is fixed to the press lever opposite side of the second pressing jaw on the first bearing a second toggle mechanism rotationally fixed relative to the pressing lever, which comprises two pivotally interconnected lever elements and on the first pressing jaw is rotatably mounted. It is thus provided on the over the entire width of the second pressing jaw extending first bearing a second toggle mechanism, which is provided parallel to the first toggle mechanism on the side of the pressing lever and serves to unbalanced force application and a possible tilting of the device due to an asymmetric force introduction to prevent.

Another measure to prevent an asymmetrical force introduction is to provide a U-shaped pressing lever instead of only one side of the device mounted pressing lever, so that symmetrically force conditions prevail on both sides with respect to the width of the first and second pressing jaw.

Preferably, a stop element is arranged on the pressing lever, which is optionally adjustable in an operative position in which the movement of the pressing lever is limited in the closed position before reaching the dead center of the toggle mechanism. Depending on the wiper body to be drained and depending on the desired degree of dewatering, a further closed position can thus be defined. By this further closed position is before reaching the dead center of the toggle mechanism, also the self-locking the device in the closed position are turned off.

The pressing jaws preferably have numerous passage openings, preferably passage slots, for the passage of cleaning fluid. In this way, the squeezed out liquid not only flows down from where it can escape downwards in the area of the joint, but the squeezed out liquid is discharged directly through the pressing jaws. By providing through-slots, a relatively large opening area can be produced, while at the same time keeping the passage slots narrow enough so that the wiping body can not partially pass through the passage openings themselves.

In order to ensure the desired power transmission of the pressing jaws on the wiping body to be squeezed out, but also to minimize twisting of the device, according to a preferred embodiment, the pressing jaws have reinforcing ribs which extend substantially vertically in the operating position. The vertical arrangement of the reinforcing ribs serves to prevent cleaning liquid, which can escape through optional passage openings in the pressing jaws to the outside, not to run down.

According to a preferred embodiment of the invention, the first pressing jaw is integrally connected to a side wall having a guide surface for the pressing lever, in particular in the region of the first bearing. The provision of a side wall has several advantages. On the one hand, it is intended to prevent objects from entering the area between the first and second pressing jaws inadvertently from the side and to be damaged during the pressing-out operation or to damage the device. Furthermore, this side wall has a guide surface or optionally also Sliding guide for the pressing lever in the area of the first bearing, whereby the toggle mechanism is exactly guided.

According to a preferred embodiment, the toggle mechanism and / or the second toggle mechanism is designed so that the elements pivotable relative to each other largely overlap. Instead of a narrow connection between the bearing points thus a wide, plate-shaped element is provided, which largely overlaps, regardless of the relative position to the respective second pivotable element of the toggle mechanism, so that there is no free space between the relatively pivotable elements in the unintentionally an object can get that can be sheared off under the high leverage of the pressing lever. Thus, this advantageous design of the pivotable relative to each other elements also serves to protect against injury to the cleaning staff.

The mop press according to the invention comprises a device for squeezing liquid-absorbing wiping bodies as described above and a collecting container to which the device can be fastened.

Preferably, the pressing jaws extend substantially over the entire width of the collecting container. This measure helps to make the entire mop compact as compact as possible.

According to a preferred embodiment of the mop press, the receptacle has a bottom and sidewalls integrally connected to the bottom, and the sidewalls have a reinforced edge on the side opposite the bottom on which the device rests with correspondingly shaped support portions. Alternatively, it is also possible, the collection container and to perform the device for pressing in one piece with each other. However, it is preferred if the device for pressing rests on a reinforced edge of the collecting container and is also removable from this.

Preferably, the mop press further comprises a positive connection between the collecting container and the device for pressing, preferably elastic elements in the region of the support portions of the device for pressing, which produce a clip connection with the reinforced edge. In this way, the device for pressing can be firmly connected to the collecting container, but also quickly and easily be solved by this again.

Preferably, the press lever is shaped such that, in the open position of the press-out device, the press lever does not extend beyond the vertical plane adjacent to the side wall of the mop press near the first press jaw. This vertical plane defines the end of the mop press in the operative position so that the press lever does not extend beyond the end of the mop press when the press lever is in the open position of the squeeze-out device. This measure serves to attach the mop press to a cleaning trolley for cleaning personnel. Due to the leverage effect, the mop press is attached to a conventional cleaning trolley so that the device placed on the receptacle for squeezing is close to the cleaning trolley, while on the side facing away from the cleaning trolley usually still extends beyond the device for squeezing, thus a Mop holder with tensioned mop cover in this area can be immersed in the cleaning liquid arranged in the collecting container during its use. Both the construction of the device for pressing with the stationarily arranged first pressing jaw as well as the arrangement of the pressing lever thus jointly serve the mop press To make as compact as possible and also to allow them to attach directly to a support frame, such as a cleaning cart. For this purpose, the mop press preferably has a suitable attachment device for fastening the mop press to a cleaning trolley.

Ways to carry out the invention

In the following figures, in each case the same components are designated by the same reference numerals.

In Fig. 1 is the generally denoted by reference numeral 10 pressing device and a mop holder 12 with mop cover stretched thereon 14 shown to illustrate the insertion of the mop holder 12 in the direction of arrow A in the squeezing device 10. The squeezing device 10 is usually placed on a collecting vessel 16, as later with reference to FIG Fig. 6a will be explained.

The squeezing device 10 has a first pressing jaw 18 and a second pressing jaw 20, which have substantially plate-shaped pressing surfaces. The pressing jaws 18 and 20 are provided with numerous openings 22, which are in the present embodiment, V-shaped mutually arranged slots and occupy an area of more than 25% of the pressing surfaces of the first pressing jaw 18 and the second pressing jaw 20. To stabilize the pressing jaws also reinforcing ribs 24 are provided, which in the Fig. 1 Installation position shown are arranged substantially vertically, so as not to hinder the drainage of squeezed liquid during operation of the squeezing device 10.

The first pressing jaw 18 is at least partially provided with side walls 26 which are integrally connected to the substantially plate-shaped first pressing jaw 18 and extend perpendicular to the plane of the plate-shaped first pressing jaw at the lateral ends thereof. The side walls are on the one hand provided with a suitable support geometry in the form of support surfaces 28 for placing the squeezing device 10 on a collecting vessel and additionally have a guide surface 30 which serves to guide a pressing lever 32, which will be described in more detail later. In addition to the guide surface 30 is the Side wall on the side of the pressing lever 32 additionally provided with a stop projection 34 which controls the movement of the pressing lever 32 in the in the Fig. 4 and 5 illustrated, closed position of the squeezing limited.

The pressing lever 32 has a handle portion 36 and a stop member 38, which consists of the in Fig. 1 shown in the shaft of the pressing lever 32 recessed position can be pivoted into an extended operative position and limited in this way the rotational movement of the pressing lever 32 into contact with the stop projection 34. In other words, the stopper member 38 can be brought into a projecting over the outer contour of the pressing lever operative position in which the pressing lever abuts against the stop projection 34 after a smaller angle of rotation and therefore the pressing jaws 18 and 20 are not brought into the fully closed position.

The first pressing jaw 18 and the second pressing jaw 20 are connected at their respective lower ends via a hinge 40 and from the in the Fig. 1 to 3 dargstellten, V-shaped arrangement to each other in the in the Fig. 5 shown arrangement pivotable in which the first pressing jaw 18 is substantially parallel to the second pressing jaw 20 to lie.

The relative pivoting between the first pressing jaw 18 and the second pressing jaw 20 takes place here exclusively by a movement of the second pressing jaw 20, since the first pressing jaw 18 is arranged stationarily in the pressing device 10. This means that the joint 40 is also arranged stationary in the extrusion device 10 and the closing movement of the extrusion device takes place exclusively by a pivoting of the second pressing jaw 20 about the joint 40.

In order to pivot the second pressing jaw 20, a pressing lever 32 is used, which is pivotable about a first bearing 42, which is located at the upper edge of the second pressing jaw 20. The toggle mechanism used will be described in more detail with reference to the following figures, but is off Fig. 1 It can be seen that, for reasons of symmetrical movement of the second pressing jaw 20 without twisting, a toggle mechanism 44 is also provided on the side of the second pressing jaw remote from the pressing lever 32, which is connected to the rotational axis of the pressing lever 32 via a rotationally rigid connection of a first toggle lever element.

The Fig. 2 shows a section through the squeezing device from the side remote from the pressing lever and makes it clear that the first pressing plate 18 is provided with reinforcing ribs 24. Furthermore, in Fig. 2 the guide surface 30 shown in the in Fig. 2 shown, fully open position of the extrusion device 10 has no function.

Out Fig. 2 It can be seen that in the open position of the squeezing device 10, the pressing lever 32 does not extend beyond the plane designated by reference numeral E, which in operating position defines the maximum horizontal extent of the squeezing device 10 without pressing lever. This has the advantage that the squeezing device 10 or the squeezing device can be used with a suitably shaped receptacle so that it can be attached to a sheet-like component such as a cleaning trolley, without affecting the function of the squeezing device, because the squeeze lever is not more can be moved to the fully open position.

Fig. 3 also shows a side view of the squeezing device 10 in the open state and the first toggle mechanism 46 used in this case.

The first toggle mechanism 46 includes a toggle portion 48, which is part of the press lever 32 and extends between the first bearing 42 for pivotally mounting the press lever 32 at the upper end of the second press jaw 18 to a second bearing 50 fixedly located on the press lever. On the second bearing 50 is pivotally mounted relative to the pressing lever 32, a toggle member 52 which is attached via a third bearing 54 in the vicinity of the upper end of the first pressing jaw 18. The third bearing 54 is thus arranged stationary relative to the squeezing device 10. How to continue Fig. 3 becomes clear, the toggle element 52 has a large extent to keep a free space between the toggle lever portion 48 and the toggle element 52 as low as possible, so that no objects inadvertently enter the free space between toggle lever portion 48 and toggle element 42 during operation of the extrusion device 10 and can be damaged during the closing movement.

Fig. 4 and 5 show the squeezing in the closed position, the representation of the Fig. 4 those after Fig. 3 corresponds and the representation after Fig. 5 those after Fig. 2 equivalent. In the illustration after Fig. 4 the pressing lever 32 has been completely pivoted to the closed position and into abutment with the stop projection 34. In this position, consisting of the toggle lever portion 48 and the toggle lever element 52 first toggle mechanism 46 is pivoted beyond the dead center, as is apparent from the position of the first axis 56 of the toggle lever portion 48 and the second axis 58 of the toggle element 52. In this position occurs a self-locking of the first Toggle mechanism on and the squeezing device 10 remains without exerting force on the pressing lever 32 in the illustrated closed position in which the second pressing jaw 20 comes to lie substantially parallel to the first pressing jaw 18. To open the squeezing device 10, the pressing lever 32 must be raised only by force over a very small angular range until the dead point is reached at which the first axis 56 is parallel to the second axis 58. After overcoming the dead center, the squeezing device can be fully opened without any effort.

In the closed position, which also in Fig. 5 is shown, the Presshebe is completely on the guide surface 30 and the mop holder 12 mounted on the mop cover 14 is dewatered between the substantially parallel pressing jaws.

In the Fig. 6a and FIG. 6b shows the squeezing device 10 fastened to the collecting vessel 16. The mop press generally designated by the reference numeral 60 in this case has a substantially cuboid collecting vessel 16 which has a closed bottom 62 and side walls 64 which have an upper edge 66 which is suitable for placing and securing the squeezing device 10. It may be a conventional flanged edge, but also a step-shaped shoulder 68 may be provided, on which the squeezing device with its bearing surfaces 28 (see also Fig. 1 ) rests.

In addition, an attachment of the squeezing device 10 on the collecting vessel 16 is advantageously provided. This attachment can be realized by a clip connection, as in the Fig. 6a and 6b is shown. To make this clip connection better visible, was in the Fig. 6a and 6b the pressure lever and the toggle mechanism not shown, as these look at the clip connection partially obstruct. As in particular in the detailed representation in Fig. 6b is shown, a fastening hook 70 may be provided on both sides of the Auspressvorrichtung 10 which is pivotable about a pin 72 and is additionally acted upon by a torsion spring in the direction of arrow B with torque, so that the barb 74 engages under the upper edge 66 of the collecting vessel and the squeezing device 10 is locked on the collecting vessel 16. However, the squeezing device 10 can be easily detached again from the collecting vessel 16 by gripping on both sides under the edge 76 and the fastening hooks 70 outwardly, ie against the arrow B outwards and pivoted against the bias of the torsion spring until the squeezing vertically lift off the top of the collecting vessel.

As well as out Fig. 6a It can be seen, preferably, the first pressing jaw 18 and the second pressing jaw 20 extend over the entire width of the collecting vessel, so that the mop is as compact as possible. The stationary first pressing jaw 18, which is essentially parallel to the one in FIG Fig. 6a not shown back wall of the collecting vessel can be arranged so that the available space is utilized in the best possible way. Preferably, the squeezing device 10 is placed on the collecting vessel 16 that the in Fig. 2 illustrated conclusion level E also at the same time corresponds to the final level of the collecting vessel arranged below. In this way, the mop 16 can be attached at a suitable location, such as on a cleaning trolley, for the attachment of the receptacle 16 on the cleaning trolley any, known in the art mounting alternative can be selected such as from the top 66 downwardly projecting vertically arranged pockets , which can be inserted into correspondingly shaped pockets on the cleaning cart as part of a vertical insertion movement. The squeezing device according to the invention and mop wringer are of particularly compact construction and the mop wringer can be fastened flush to a cleaning trolley on its rear side since this does not hinder the pivoting range of the lever. The operation of the squeezing device is simple, since with a single movement the squeezing device is closed and with a movement in the reverse direction of swiveling it can be opened again. In addition, without the application of force, the squeezing device can be held in the closed position because a toggle mechanism is used that has been moved past its dead center in the closed position. All these measures work together to design a user-friendly, because compact and easy-to-use squeezing device for a mop press.
