Description
Mop-head plate The invention relates to a mop-head plate comprising a main body, to which a first mop-head-plate wing, a second mop-head-plate wing and a joint are attached, wherein the mop-head-plate wings can be pivoted between a working position and a wringing-out position.
Such a mop-head plate is known, for example, from DE 10 2012 007 525 Al.
The mop-head plate forms part of a mop, wherein, in addition to the mop-head plate, the mop has a handle, which is connected to the mop-head plate via the joint. The mop-head plate is assigned a mop cover, which is fastened in a releasable manner on the mop-head plate such that it can be brought into contact with the floor which is to be cleaned. The mop-head plate here pushes the mop cover flat onto the floor which to be cleaned.
In order for the mop cover to be wrung out, the mop-head-plate wings are transferred from the working position into the wringing-out position. The mop cover here hangs down in the form of a loop from the mop-head plate. The mop cover hanging down in this way from the mop-head plate can be wrung out in a basket-like wringer by virtue of the mop being pushed into same. It is also known for the mop covers to be pushed into a rotatable wringer, in which the mop cover is wrung out as result of rapid rotation of the wringer basket together with the mop-head plate. In both cases, it is advantageous, for straightforward introduction of the mop, if the mop-head plate with the mop cover is pushed into the wringer in a straight position. The problem of a manual wringer, in which the mop-head plate is wrung out as result of being pushed in, is that the joint can tilt during the pushing-in action, which reduces the force which can be applied and impairs the performance results.

2 The object of the invention is to provide a mop-head plate which is particularly easy to feed into a wringer.
This object is achieved by the features of claim 1. The dependent claims refer to advantageous configurations.
The object is achieved by the main body having arranged in it a device for arresting the joint, said device fixing the joint along the longitudinal axis when the mop-head-plate wings are located outside the working position. The joint is fixed along the longitudinal axis by the arresting device in particular when the mop-head-plate wings pivot from the working position into the wringing-out position. To this extent, fixing is also provided according to the invention when the mop-head-plate wings are located in the wringing-out position. This ensures that it is no longer possible for the joint to pivot or tilt while the mop-head plate is being pushed into the wringer basket. This makes it possible for the entire force which is applied to the mop-head plate via the handle to be used for the wringing-out work. This improves the wringing-out result.
The joint is designed preferably in the form of a universal joint. This makes it possible to pivot the joint with the handle together both in the longitudinal direction and in the transverse direction relative to the mop-head plate.
The joint has preferably a first joint body and a second joint body, wherein the first joint body is arranged preferably in a pivotable manner on the main body and the second joint body is arranged in a pivotable manner on the first joint body, wherein the pivot axis between the first joint body and second joint body is oriented transversely in relation to the pivot axis between the first joint body and main body. This arrangement gives rise to the universal joint.
The second mop-head-plate wing can have projecting elements, which are designed such that the second mop-head-plate wing engages in a U-shaped Date Recue/Date Received 2020-11-27

3 manner, by way of the elements, around the main body and the joint, which is assigned to the main body. In the case of such a configuration, the elements pivot in the direction of the joint, and thus block the joint, as the mop-head-plate wings pivot. The elements overlap the joint in the region of the main sides, that is to say of the front edge and of the rear edge, of the mop-head plate. When the mop-head-plate wings are in the folded state, the elements prevent the handle from being able to pivot in the direction of the main sides.
The elements can be assigned stop elements which, in the wringing-out position, are oriented in the direction of the joint. The stop elements can increase the size of the stop region and thus provide for improved fixing of the joint.
The first joint body can accommodate a resilient needle, which projects through a longitudinal opening made in the first joint body. The second joint body can have an aperture which is congruent with the longitudinal opening when the second joint body is aligned in the direction of the longitudinal axis relative to the first joint body. This is the case when the pivot axis is 00, or in the region of 0 , both in the longitudinal direction and in the transverse direction.
This configuration allows the joint body to be fixed when the two joint bodies are aligned along the longitudinal axis. The longitudinal opening accommodates the resilient needle, wherein the resilient needle penetrates into the aperture when the second joint body is aligned in the direction of the longitudinal axis relative to the first joint body. As result, the two joint bodies are fixed in relation to one another and are no longer able to pivot automatically.
The resilient needle can have a pin-like needle portion, which is arranged in the bore, and a resilient portion, which is arranged in a further transverse opening which is open in the direction of the main body, and therefore, as the mop-head plate pivots from the working position into the wringing-out position, the two Date Regue/Date Received 2020-11-27

4 mop-head-plate wings come into contact with the resilient portion and push the resilient needle through the longitudinal opening in the direction of the aperture of the second joint body. This ensures that the resilient needle penetrates into the aperture only when the mop-head-plate wings are transferred from the working position into the wringing-out position.
In the working position, in contrast, the resilient needle is located only in the longitudinal opening, and therefore the first joint body can be pivoted in relation to the second joint body. The configuration in the form of the resilient portion makes it possible for prestressing of the resilient needle to be built up during pivoting, and therefore pivoting of the mop-head-plate wings is possible even when the handle is not aligned with the longitudinal axis. If, once the mop-head-plate wings have been pivoted from the working position into the wringing-out position, the handle is aligned with the longitudinal axis, the resilient needle, in contrast, springs automatically into the aperture on account of the prestressing.
As the mop-head-plate wings transfer from the wringing-out position into the working position, the prestressing of the resilient portion decreases until the resilient portion, after reaching the working position, is free and the needle portion is arranged in a freely movable manner in the aperture and longitudinal opening. The action of gravitational force means that the resilient needle leaves the aperture automatically and remains merely in the longitudinal opening. The two joint bodies can then be pivoted freely in relation to one another again.
The resilient portion can be assigned an intermediate element which, as the mop-head-plate wings transfer from the working position into the wringing-out position, comes into contact with the resilient portion and causes the needle portion to be pushed through the longitudinal opening into the aperture. In the working position, the intermediate element is preferably at a distance from the resilient portion, and therefore the needle portion moves automatically out of the aperture and the two joint bodies are freed.

Date Recue/Date Received 2020-11-27 Two laterally projecting protrusions can be formed from the joint and rest on sliding surfaces formed from the main body. The protrusions here project in the direction of the narrow sides of the mop-head plate and rest on the sliding
5 surfaces in the region of the free ends of the protrusions. Essentially semicircular elevations can be formed from the main body, wherein the outer contours of the semicircular elevations form the sliding surfaces. On the upper side of the elevations, that is to say on that side of the elevations which is directed away from the main body, a plateau is formed from the sliding surfaces.
The plateau is preferably designed such that it projects beyond the sliding surfaces, and therefore a respective step is formed at the two transitions from plateau to sliding surface.
During the cleaning work, the handle is usually pivoted by an angle of between 45 and 800 in relation to the longitudinal axis. In this angle range, the protrusions rest on the curved sliding surfaces and the mop-head plate can be pivoted in relation to the handle.
In particular when the cleaning appliance is moved rearward, the mop-head plate can be subjected to a force which causes the mop-head plate to flip over, and therefore the mop cover is no longer resting on the floor which is to be cleaned. This is the case, in particular, with mop covers which are only slightly damp and with dull floors. The step in the region of the transition between the curved sliding surfaces and the plateau sets against the protrusions a resistance which prevents the mop-head plate from flipping over when the mop-head plate is moved rearward during cleaning work.

9 The mop-head-plate wings 3, 4 are provided with a device 25 for fastening a mop cover. In the case of the present configuration, said device comprises apertures which are made in the peripheral regions of the narrow sides of the mop-head-plate wings 3, 4 and serve to accommodate snap fasteners of a mop cover. This means that the mop cover is fixed to the mop-head plate 1 even in the wringing-out position 7, and therefore the mop cover can be wrung out in a wringer in a state in which it hangs down from the mop-head plate I.
The main body 2 is assigned a fixing device 8 for arresting the joint 5, said device fixing the joint 5 along the longitudinal axis 9 of the joint 5 in the wringing-out position 7.
As the mop-head-plate wings 3, 4 pivot, the projecting elements 26 of the second mop-head-plate wing 4 pivot in the direction of the joint 5. As result, the joint 5 is blocked and cannot pivot in the direction of the elements 26. The elements 26 are assigned stop elements 32, which increase the size of the contact surface area between the elements 26 and joint 5. To this extent, the elements 26 form part of the fixing device 8 and limit the movement capability of the joint 5 in the pivoting direction oriented in the direction of the main sides of the mop-head-plate wings 3, 4.
The joint 5 is designed in the form of a universal joint and has a first joint body 15 and a second joint body 16. The first joint body 15 is arranged in a pivotable manner on the main body 2. The second joint body 16 is arranged in a pivotable manner on the first joint body 15, wherein the pivot axis between the first joint body 15 and second joint body 16 is oriented transversely in relation to the pivot axis between the first joint body 15 and main body 2, this giving rise to a universal joint.
In a further part of the fixing device 8, the first joint body 15 accommodates a resilient needle 17, which projects through a longitudinal opening 18 made in Date Recue/Date Received 2020-11-27 the first joint body 15. The second joint body 16 has an aperture 19 which is congruent with the longitudinal opening 18 of the first joint body 15 when the second joint body 16 is aligned in the direction of the longitudinal axis 9 relative to the first joint body 15.
The resilient needle 17 has a needle portion 20, which is arranged in the longitudinal opening 18, and a resilient portion 21, which is arranged in a transverse opening 22 which is made in the first joint body 15 and is open in the direction of the main body 2. As the mop-head-plate wings 3, 4 pivot from the
The main body 2 is assigned a fixing device 8 for arresting the joint 5, said device fixing the joint 5 along the longitudinal axis 9 of the joint 5 in the wringing-out position 7.
As the mop-head-plate wings 3, 4 pivot, the projecting elements 26 of the second mop-head-plate wing 4 pivot in the direction of the joint 5. As result, the joint 5 is blocked and cannot pivot in the direction of the elements 26. The elements 26 are assigned stop elements 32, which increase the size of the contact surface area between the elements 26 and joint 5. To this extent, the elements 26 form part of the fixing device 8 and limit the movement capability of the joint 5 in the pivoting direction oriented in the direction of the main sides of the mop-head-plate wings 3, 4.
The joint 5 is designed in the form of a universal joint and has a first joint body 15 and a second joint body 16. The first joint body 15 is arranged in a pivotable manner on the main body 2. The second joint body 16 is arranged in a pivotable manner on the first joint body 15, wherein the pivot axis between the first joint body 15 and second joint body 16 is oriented transversely in relation to the pivot axis between the first joint body 15 and main body 2, this giving rise to a universal joint.
In a further part of the fixing device 8, the first joint body 15 accommodates a resilient needle 17, which projects through a longitudinal opening 18 made in Date Recue/Date Received 2020-11-27 the first joint body 15. The second joint body 16 has an aperture 19 which is congruent with the longitudinal opening 18 of the first joint body 15 when the second joint body 16 is aligned in the direction of the longitudinal axis 9 relative to the first joint body 15.
The resilient needle 17 has a needle portion 20, which is arranged in the longitudinal opening 18, and a resilient portion 21, which is arranged in a transverse opening 22 which is made in the first joint body 15 and is open in the direction of the main body 2. As the mop-head-plate wings 3, 4 pivot from the
10 working position 6 into the wringing-out position 7, the mop-head-plate wings 3, 4 come into contact, via an intermediate element 27, with the resilient portion 21, which in turn pushes the needle portion 20 through the longitudinal opening 18 in the direction of the aperture 19 of the second joint body 16. If the joint 5 is aligned with the longitudinal axis 9, the needle portion 20 is pushed into the aperture 19, and therefore the first joint body 15 and the second joint body are fixed in relation to one another along the longitudinal axis 9. If the two joint bodies 15, 16 have not yet been fully aligned in relation to one another, the needle portion 20 butts under prestressing against the second joint body 16, and the needle portion 20 pushes automatically into the aperture 19 when the two joint bodies 15, 16 are finally aligned along the longitudinal axis 9. If the mop-head-plate wings 3, 4 are moved from the wringing-out position 7 into the working position 6, the mop-head-plate wings 3, 4 move away from the intermediate element 27 and the prestressing of the resilient portion 21 on the needle portion 20 decreases, as result of which the needle portion 20 moves automatically out of the aperture 19.
Two laterally projecting protrusions 10, 11 are formed from the joint 5 and rest on essentially semicircular sliding surfaces 12, 13 formed from the main body 2.
The sliding surfaces 12, 13 have a plateau 14, wherein the plateau 14 is designed such that a step is formed at the transition between curved sliding surface 12, 13 and plateau 14. If the joint 5 has been oriented obliquely in Date Recue/Date Received 2020-11-27

11 relation to the longitudinal axis 9 during the cleaning work, the protrusions 10, 11 rest on the circular portions of the sliding surfaces 12, 13. If, then, the joint 5 is pivoted in the direction of the longitudinal axis 9, the protrusions 10, 11 are displaced on the sliding surfaces 12, 13 in the direction of the plateau 14, wherein the protrusions 10, 11 are deformed once they reach the step. This increases the resistance against any further pivoting of the joint 5, and therefore the mop-head plate 1 does not flip over during cleaning work.
