Description
Description
The invention relates to a wringer device for a mopping unit, comprising a basket-like receptacle, which is arranged in a rotatable manner in a holder, wherein the receptacle can be made to rotate via a mechanical drive, wherein the drive has a lever which is mounted in a movable manner in the holder, wherein the receptacle is set in rotation by means of a gear mechanism when the lever is activated.
A wringer device of this type is known from DE 20 2008 014 219 Ul. The wringer device described therein is particularly suitable for wringing a mop. Although a mop can in principle also be wrung out by means of a rigid wringer device into which the mopping unit is pressed in order to remove the cleaning fluid, it has however been found that a spinning process designed for the wiper cover or mop carried out by a rotating wringer device is substantially more effective than wringing out the mop cover by way of compression. In the wringer device known from the prior art, a basket-like receptacle is set in rotation by means of a foot-activated lever. The lever is arranged in the bottom region of the mop bucket and drives the receptacle via a gearwheel transmission with freewheel. The freewheel ensures that the receptacle rotates in one direction only. This permits higher rotational speeds to be achieved.
WO 2017/102133
PCT/EP2016/074564
A disadvantage, however, is that relatively large gearwheels have to be used on account of the required transmission ratio, which gearwheels cannot, however, be covered on account of their assignment to the lever. As a result, there is a certain risk of injury to the user. Due to the large acting forces, the gearwheels are subject to relatively high wear.
It is the object of the present invention to present a wringer device which is robust whilst having minimum space requirements.This object is achieved with the features of claim 1. The dependent claims refer to advantageous embodiments.
The wringer device for a mopping unit achieving the object comprises a basket-like receptacle which is arranged in a holder in a rotatable manner, wherein the receptacle can be set in rotation by means of the mechanical drive, wherein the drive has a lever, which is mounted in the holder in a movable manner and is provided with a spindle nut, which causes a spindle to rotate when the lever is moved, wherein a first gearwheel is arranged on the spindle in a rotationally fixed manner, wherein a second gearwheel is associated with the axis of rotation of the receptacle, wherein a freewheel is arranged between the axis of rotation and the second gearwheel, which freewheel allows torque transmission to the axis of rotation in only one direction of rotation, wherein a toothed belt is arranged between the first gearwheel and the second gearwheel.
Transformation of the translational movement caused by the lever movement into a rotational movement is achieved by the combination of the spindle nut, which is fastened to the lever, with a spindle which is mounted in the holder in a rotatable manner.
WO 2017/102133
PCT/EP2016/074564
When the lever is activated by the user's foot, i.e. moved from an initial positioin to an end position, the spindle nut, which is mounted on the lever in a rotationally fixed manner, moves along the axis of the spindle. As a result, the spindle is set in rotation. A gearwheel which is arranged in a rotationally fixed and positionally fixed manner on the spindle, and which rotates with the spindle, transmits the rotation to a second gearwheel via a toothed belt. The second gearwheel is in turn fastened to the axis of rotation of the receptacle.
A freewheel is provided between the second gearwheel and the axis of rotation, which allows torque to be transmitted to the axis of rotation in one direction of rotation only. As a result, torque is transmitted to the axis of rotation only when the lever is moved from the initial position into the end position. If, on the other hand, the lever is moved from the end position into the initial position in a rearward movement, i.e. when the spindle reverses the direction of rotation, no torque is transmitted. As a result, the receptacle can reach very high rotational speeds, resulting in an effective spinning of the wiping cover located in the receptacle.
The receptacle has slots or other openings through which the discharged cleaning fluid is conveyed into the mop bucket.
The combination of spindle drive and toothed belt drive makes it possible to drive the receptacle with minimum space requirement. In addition, the toothed belt drive can be encapsulated with the two gearwheels and the toothed belt so that intervention by the user or other external effects can be excluded.
WO 2017/102133
PCT/EP2016/074564
Only the spindle with the spindle nut is partially open due to the assignment to the lever. However, only low risk of injury exists in the case of a spindle drive. Both a spindle drive and the toothed belt drive are very robust components and allow the production of a wringer device which is robust and has a long service life.
The lever can have a spring element assigned which, in the unloaded state, automatically moves the lever into the initial position.
When the receptacle is to be set in rotation, the lever is moved from the initial position into an end position. As a result, the spindle nut is displaced in the axial direction of the spindle and the spindle rotatably mounted in the holder is thereby set in rotation. The rotation is transmitted to the receptacle via the toothed belt drive. To enable the lever to automatically move from the end position into the initial position, a spring element is provided which moves the lever back when the latter is unloaded. As a result, the movement from the initial position into the end position can be repeated in rapid succession, so that a high rotational speed can be achieved.
In a first embodiment, the lever is mounted in a parallel guide. In this embodiment, the lever is preferably oriented approximately parallel to the bottom plate of the wringer device, wherein this orientation is also maintained during the movement of the lever from the initial position into the end position. This configuration offers the advantage that no transverse forces are introduced into the receptacle, because no tilting movement of the lever occurs.
In order to achieve parallel guidance, the lever can have recesses through which guide elements project which are fixed to the receptacle. The guide elements are rigidly fastened in the holder. During the activation of the lever, said lever slides along the guide elements from the initial position into the end position. In this embodiment, the
PCT/EP2016/074564
WO 2017/102133 spring element, which automatically moves the lever back into the initial position in the unloaded state, can be arranged either on the spindle or on the guide elements. The spring element can be a simple spiral spring.
In a further embodiment, the lever can be fixed to the receptacle in a rotatable and tiltable manner at one free end, wherein the lever, according to a first alternative, is rotatably fixed to the receptacle on the free end facing the axis of rotation and, according to a second alternative, is fixed to the free end facing away from the axis of rotation.
In the first alternative, the lever protrudes upwards at the free end facing the user. This represents the initial position. In order to activate the lever, it is necessary for the user to lift his foot and place it on the lever. The advantage here is that the user can introduce great force into the lever. The disadvantage is that the use can be unreliable due to the required lifting of the foot.
In the second variant, the end of the lever facing the user represents the pivot point which is arranged on the bottom plate of the holder. As a result, the user can set the foot comfortably and securely onto the lever. The disadvantage here is that not much force can be applied to the lever.
The lever can be adustable in length. Here, it is feasible for an extension of the lever to be translationally pulled from within the lever. By virtue of the extension of the lever, the lever arm is increased and thus the force introduced into the wringer device.
WO 2017/102133
PCT/EP2016/074564
The pitch of the spindle can be variable. In particular, it is conceivable that the pitch of the spindle is designed in such a way, that it is greater in at least one edge region than in the middle region. In the region with a greater pitch, the ratio of the distance travelled by the spindle nut to the number of revolutions of the spindle is increased.. Due to the extended path of travel, the force required to set the receptacle in rotation is again reduced. This is particularly useful in the reversal points of the spindle and immediately at the start of the activation of the lever. In particular, in connection with the variant wherein the lever is fixed to the free end facing away from the axis of rotation, achieving a high force input may result whilst at the same time offering a comfortable operation.
The spindle nut is preferably mounted tiltably in the lever. In addition, the spindle nut can be mounted in the lever in such a way that it can move relative to the longitudinal axis of the lever. As a result, the spindle nut can drive the spindle without impeding transverse or shear forces occurring.
Some embodiments of the wringer device according to the invention are explained schematically in the following with reference to the figures.

The figures show a wringer device 1 for a mopping unit, comprising a basket-like receptacle 2 which is rotatably arranged in a holder 3. The holder 3 comprises a bottom plate 18 onto which the components of the wringer device 1 are fastened. The bottom plate 18 can in turn be fastened in the mop bucket, for example by means of screws. A mop bucket equipped for integrating a wringer device 1, has an indentation on the outside in the bottom region, which indentation partially receives the wringer device 1 with the bottom plate 18. The indentation has an opening, through which the axis of rotation 9 of the receptacle 2 protrudes. The receptacle 2, in turn, is arranged in the interior of the mop bucket. Only the axis of rotation 9 passes through the wall of the bucket. The bottom plate 18, with regard to its extension, is designed in such a way that the latter protrudes so far out of the mop bucket that tilting moments introduced by the lever 5 are intercepted.
The receptacle 2 has slot-shaped openings, through which the cleaning fluid spun out from the mop cover or the mop is expelled into the bucket.
The receptacle 2 can be set in rotation by means of a mechanical drive 4. For this purpose, the drive 4 has a lever 5, which is movably mounted in the holder 3 and is provided with a spindle nut 6. The spindle nut 6 sets a spindle 7 in rotation when the lever is moved, wherein a first gearwheel 8 is arranged in a rotationally fixed manner on the spindle 7. The axis of rotation 9 of the receptacle 2 is in turn associated with a second gearwheel 10, in which case a freewheel 11 is arranged between the axis of rotation 9 and the second gearwheel 10, which freewheel 11 only in one direction of rotation allows a torque transmission from the second gearwheel 10 onto the axis of rotation 9. Between the first gearwheel 8 and the second gearwheel 10, a toothed belt 12 is arranged.
WO 2017/102133
PCT/EP2016/074564
The spindle 7 is mounted in the holder in a rotationally movable manner. The spindle 7 is preferably supported by means of plastic bearings 23. The freewheel 11 arranged between the second gearwheel 10 and the axis of rotation 9 is preferably designed as a freewheel roller. In this case, the second gearwheel 10 and the freewheel 11 form a preassembled unit.
In this case, the wringer device 1 can be designed in such a way, that the first gearwheel 8 and the second gearwheel 10 are encapsulated with the freewheel 11 and the toothed belt 12. For this purpose, for example, a cover can be provided which covers the rotating components of the wringer device 1. As a result, manual access to these components is excluded.
Figure 1 shows a first embodiment of the wringer device 1. In this embodiment, the lever 5 is mounted in a parallel guide 15. For this purpose, the lever 5 has recesses 19, through which guide elements 16 fixed at the receptacle 2 project. In the present embodiment, two circular recesses 19 are provided in the lever 5. The guide elements 16 are formed in a column-like manner and are fastened to the bottom plate 18. When the lever 5 is activated from the initial position 14 into the end position 17, the lever 5 slides parallel to the guide elements 16, wherein the orientation relative to the bottom plate 18 remains substantially unchanged.
A spring element 13 is associated with the lever 5, said spring element automatically moving the lever 5 into the initial position 14 in the unloaded state. In this embodiment, the spring element 13 is designed as a spiral spring and is plugged onto the spindle 7.
WO 2017/102133
PCT/EP2016/074564
Figure 2 shows a second embodiment of the wringer device 1. In this configuration, the lever 5 is fixed to one free end in a rotatable and tiltable manner to the receptacle 2.
In the embodiment shown in FIG. 2, this is done in such a way, that the lever 5 is rotatably fixed to the receptacle 2 at the free end facing the axis of rotation 9. As a result, the free end of the lever 5, which faces the user, is spaced at a distance from bottom plate 18 in the initial position 14. The lever 5 is fastened to the holder 3 via a joint 20. For this purpose, a projection is formed from the base plate 18, which accommodates the joint 20. The spring element 13 is associated with joint 2O.The lever 5 is rotatably movable along lever path of travel 24.
The spindle nut 6 is mounted in the lever 5 so as to be pivotable and displaceable along the longitudinal axis of the lever 5. For this purpose, an opening 21 is arranged in the lever 5, which accommodates the spindle nut 6. The opening 21 is adjoined by two elongated holes 22 which, on the one hand, facilitate the pivotal support of the spindle nut and on the other a longitudinal displacement of the spindle nut within certain limits.
Figure 3 shows in greater detail the lever 5 and its movement with the spindle nut 6 relative to the spindle 7. The position spaced at a distance from the bottom plate 18 is the initial position 14 and the position facing the base plate 18 is the end position 17. The lever 5 is moved by the foot of the user from the initial position 14 to the end position 17 and due to the spring tension of the spring element 13 returns automatically from the end position 17 into the initial position 14. By a rhythmic activation of the lever 5, the receptacle 2 is set in rotation, thereby facilitating high rotational speeds to be achieved.

PCT/EP2016/074564
Figure 4 shows a further embodiment of the wringer device 1. In this embodiment, which substantially corresponds to the embodiment in Fig. 2, the lever 5 is rotatably fixed to the receptacle at the free end facing away from the rotational axis 9. As a result, the joint 20 with the integrated spring element 13 is facing the user so that for activating the lever 5 with the integrated spring element 1, the foot may remain placed on the lever 5 during the entire activation of the lever 5. The spindle nut 6 is supported in the same manner as described in the embodiment according to Figure 2.
Figure 5 shows the initial position 14 and the end position 17 of the lever 5 in the embodiment of the wringer device 1 as shown in Figure 4.
In this embodiment, the pitch of the spindle 7 is variable, wherein the pitch of the spindle 7 is designed in such a way that, in the region of the initial position 14 of the lever 5, which corresponds to an edge region of the spindle 7, the pitch is greater than in the middle region.
