Description

The invention relates to a mop plate comprising a base body to which a first mop plate wing, a second mop plate wing and a joint are connected, wherein the mop plate wings can be pivoted between a working position and a wringing position.

Such a wiper plate is, for example, from the EN 10 2012 007 525 A1 known. The mop plate forms part of a mop device, whereby the mop device has a handle in addition to the mop plate, which is connected to the mop plate via the joint. The mop plate is assigned a mop cover, which is detachably attached to the mop plate so that it can be brought into contact with the floor to be cleaned. The mop plate presses the mop cover flat onto the floor to be cleaned.

To wring out the mop cover, the mop plate wings are moved from the working position to the wringing position. The mop cover hangs down from the mop plate in the form of a loop. The mop cover hanging down from the mop plate can be wrung out in a basket-shaped wringing device by pressing the mop device. It is also known that the mop covers are pressed into a rotating wringing device in which the mop cover is wrung out together with the mop plate by quickly rotating the wringing basket. In both cases, it is advantageous for easy insertion of the mop device if the mop plate with the mop cover is placed straight into the wringing device. is pressed in. With a manual wringing device, where wringing is done by pressing in the wiping plate, it is problematic that the joint can tilt during pressing in, which reduces the force that can be applied and worsens the execution result.

From the EN 10 2005 044 507 A1 A mop plate is known which is connected to a handle in an articulated manner, whereby the articulated connection can be locked via a locking device. The CN 2887238 Y shows a butterfly mop in which the mop plate is connected to the handle via several joints, whereby the joints block each other in the wringing position.

The invention is based on the object of providing a wiping plate which can be fed particularly easily to a wringing device.

This object is achieved with the features of claim 1. The subclaims refer to advantageous embodiments.

To solve the problem, a device for locking the joint is arranged in the base body, which fixes the joint along the longitudinal axis when the mop plate wings are outside the working position. In particular, the joint is fixed along the longitudinal axis by the device for locking when the mop plate wings pivot from the working position into the wringing position. In this respect, fixation is also provided according to the invention when the mop plate wings are in the wringing position. This ensures that the joint can no longer pivot or tilt when the mop plate is pressed into the wringing basket. This means that all of the force introduced into the mop plate via the handle can be used for the wringing work. This improves the wringing result.

The joint is preferably designed as a universal joint. This allows the joint and the handle to be pivoted both longitudinally and transversely relative to the wiping plate.

The joint has a first joint body and a second joint body, wherein the first joint body is preferably arranged pivotably on the base body and the second joint body is arranged pivotably on the first joint body, wherein the pivot axis between the first joint body and the second joint body is aligned transversely to the pivot axis between the first joint body and the base body. The universal joint results from this arrangement.

The second mop plate wing can have protruding elements which are designed in such a way that the second mop plate wing, through the elements, encompasses the base body and the joint associated with the base body in a U-shape. With such a design, the elements pivot in the direction of the joint when the mop plate wings pivot, thereby blocking the joint. The elements cover the joint in the area of the main sides, i.e. the front edge and the rear edge of the mop plate. When the mop plate wings are folded, the elements prevent the handle from pivoting in the direction of the main sides.

The elements can be assigned stop elements which point in the direction of the joint in the wringing position. The stop elements can enlarge the stop area and thus improve the fixation of the joint.

According to the invention, the first joint body accommodates a spring needle which projects through a longitudinal opening made in the first joint body. The second joint body can have a recess which is congruent with the longitudinal opening when the second joint body is aligned relative to the first joint body in the direction of the longitudinal axis. This is the case when the pivot axis is 0° in both the longitudinal and transverse directions, or is in the range of 0°.

This design enables the joint body to be fixed when both joint bodies are aligned along the longitudinal axis. The longitudinal opening accommodates the spring needle, whereby the spring needle penetrates into the recess when the second joint body is aligned relative to the first joint body in the direction of the longitudinal axis. This fixes both joint bodies to one another and means that they can no longer pivot on their own.

The spring needle has a pin-like needle section which is arranged in the bore, and a spring section which is arranged in a further transverse opening which is open in the direction of the base body, so that when the mop plate is pivoted from the working position to the wringing position, the two mop plate wings come into contact with the spring section and press the spring needle through the longitudinal opening in the direction of the recess of the second joint body. This ensures that the spring needle only penetrates the recess when the mop plate wings are moved from the working position to the wringing position.

In the working position, however, the spring needle is only in the longitudinal opening, so that the first joint body can be pivoted towards the second joint body. Due to the design as a spring section, a preload can be built up on the spring needle during pivoting, so that the mop plate wings can be pivoted even if the handle is not aligned with the longitudinal axis. If, after pivoting the mop plate wings from the working position to the wringing position, the handle is aligned with the longitudinal axis, the spring needle automatically jumps into the recess due to the preload.

When the wiper plate wings are moved from the wringing position to the working position, the pre-tension on the spring section is reduced until the spring section is free after reaching the working position and the needle section is freely movable in the recess and longitudinal opening. Due to the effect of gravity, the spring needle automatically leaves the recess and simply remains in the longitudinal opening. The two joint bodies can then pivot freely towards each other again.

An intermediate element can be assigned to the spring section, which comes into contact with the spring section when the wiper plate wings are transferred from the working position to the wringing position and causes the needle section to be pressed through the longitudinal opening into the recess. In the working position, the intermediate element is preferably spaced apart from the spring section, so that the needle section automatically moves out of the recess and the two joint bodies are released.

Two projections can be formed from the joint that protrude laterally and rest on sliding surfaces formed from the base body. The projections protrude in the direction of the narrow sides of the wiping plate and rest on the sliding surfaces in the area of the free ends of the projections. Essentially semicircular elevations can be formed from the base body, with the outer contours of the semicircular elevations forming the sliding surfaces. A plateau made of the sliding surfaces is formed on the top of the elevations, i.e. the side of the elevations facing away from the base body.

The plateau is preferably designed in such a way that it projects beyond the sliding surfaces, so that a step is formed at each of the two transitions from plateau to sliding surface.

During cleaning, the handle is usually swiveled at an angle of between 45° and 80° to the longitudinal axis. In this angle range, the projections rest on the curved sliding surfaces and the wiping plate can be swiveled relative to the handle.

Particularly when the cleaning device is moved backwards, a force can act on the mop plate, causing the mop plate to fold over so that the mop cover no longer rests on the floor to be cleaned. This is particularly the case with mop covers that are only slightly damp and with dull floors. The step in the area of the transition between the curved sliding surfaces and the plateau provides resistance to the projections, which prevents the mop plate from folding over when the mop plate is moved backwards during cleaning.

The figures show a mop plate 1 with a base body 2, to which a first mop plate wing 3 and a second mop plate wing 4 are pivotably connected. The base body 2 is assigned a joint 5, here a universal joint, which can be connected to a handle. The mop plate wings 3, 4 can be reversibly fixed in a working position 6. In the working position 6, the two mop plate wings 3, 4 are essentially aligned in one plane. By operating a foot pedal 23, the mop plate wings 3, 4 can be pivoted from the working position 6 into a wringing position 7.

The wiping plate 1 and the wiping plate wings 3, 4 have a top side and a bottom side that forms the wiping surface. The bottom sides of the first wiping plate wing 3 and the second wiping plate wing 4 move towards each other when the wiping plate wings 3, 4 are pivoted from the working position 6 into the wringing position 7. In the wringing position 7, the two bottom sides of the two wiping plate wings 3, 4 are opposite each other.

The foot pedal 23 is pivotably mounted on the first mop plate wing 3 and is designed such that the foot pedal 23 fixes the second mop plate wing 4 in the working position 6. The foot pedal 23 is further designed such that the second mop plate wing 4 pivots relative to the first mop plate wing 3 when the foot pedal 23 is actuated.

The foot pedal 23 is connected in an articulated manner to the first mop plate wing 3, wherein the foot pedal 23 has a first free end protruding from the first mop plate wing 3, which forms the actuating section of the foot pedal 23. Furthermore, the foot pedal 23 has a second free end protruding in the direction of the second mop plate wing 4, which forms the locking section of the foot pedal 23.

The foot pedal 23 has two projections 28, 29, which are associated with the locking section. The two projections 28, 29 are designed as Spring elements are formed and in the working position 6 are assigned to the underside of the second wiper plate wing 4. The two projections 28, 29 rest there with elastic preload.

The second wiper plate wing 4 has projecting elements 26 which are designed such that the second wiper plate wing 4 together with elements 26 surrounds the base body 2 in a U-shape. Holding elements 31 are formed from the foot pedal 23, which engage over the elements 26 of the second wiper plate wing 4 and thereby, together with the projections 28, 29, fix the wiper plate wings 3, 4 in the working position 6.

If the foot pedal 23 is actuated, the holding elements 31 move away from the second mop plate wing 4 and release the second mop plate wing 4 for pivoting. At the same time, the two projections 28, 29 press against the underside of the second mop plate wing 4 and thereby pivot the second mop plate wing 4 relative to the first mop plate wing 3 by actuating the foot pedal 23.

The first wiping plate wing 3 and the second wiping plate wing 4 each have a toothing, whereby the teeth of the toothing engage with each other. As a result, both wiping plate wings 3, 4 pivot simultaneously relative to the base body 2. In the wringing position 7, both wiping plate wings 3, 4 are located below the base body 2, or in a straight line to the handle, the joint 5 and the base body 2.

The first wiper plate wing 3, the second wiper plate wing 4 and the foot pedal 23 are positively locked in the working position 6.

The base body 2, the wiper plate wings 3, 4 and the joint 5 are made of injection-moldable plastic. The underside of the wiper plate wings 3, 4 is provided with a structure in the form of ribs 24. The ribs 24 enable a high local surface pressure of the mop cover on the floor to be cleaned. This improves the cleaning performance.

The mop plate wings 3, 4 are provided with a device 25 for attaching a mop cover. In the present embodiment, this consists of recesses which are provided in the edge areas of the narrow sides of the mop plate wings 3, 4 and serve to accommodate push buttons of a mop cover. As a result, the mop cover is firmly connected to the mop plate 1 even in the wringing position 7, so that the mop cover can be wrung out in a wringing device while hanging from the mop plate 1.

The base body 2 is assigned a fixing device 8 for locking the joint 5, which fixes the joint 5 in the wringing position 7 along the longitudinal axis 9 of the joint 5.

When the mop plate wings 3, 4 are pivoted, the projecting elements 26 of the second mop plate wing 4 pivot in the direction of the joint 5. As a 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 contact area between the elements 26 and the joint 5. In this respect, the elements 26 form part of the fixing device 8 and limit the mobility of the joint 5 in the pivoting direction pointing towards the main sides of the mop plate wings 3, 4.

The joint 5 is designed as a universal joint and has a first joint body 15 and a second joint body 16. The first joint body 15 is pivotably arranged on the base body 2. The second joint body 16 is pivotably arranged on the first joint body 15, wherein the pivot axis between the first joint body 15 and the second Joint body 16 is aligned transversely to the pivot axis between first joint body 15 and base body 2, so that a universal joint is formed.

In a further part of the fixing device 8, the first joint body 15 receives a spring needle 17, which projects through a longitudinal opening 18 made in the first joint body 15. The second joint body 16 has a recess 19, which is congruent with the longitudinal opening 18 of the first joint body 15 when the second joint body 16 is aligned relative to the first joint body 15 in the direction of the longitudinal axis 9.

The spring needle 17 has a needle section 20 which is arranged in the longitudinal opening 18 and has a spring section 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 base body 2. When the mop plate wings 3, 4 are pivoted from the working position 6 into the wringing position 7, the mop plate wings 3, 4 come into contact with the spring section 21 via an intermediate element 27, which in turn presses the needle section 20 through the longitudinal opening 18 in the direction of the recess 19 of the second joint body 16. If the joint 5 is aligned with the longitudinal axis 9, the needle section 20 is pressed into the recess 19 so that the first joint body 15 and the second joint body 16 are fixed to one another along the longitudinal axis 9. If the two joint bodies 15, 16 are not yet fully aligned with each other, the needle section 20 rests against the second joint body 16 with pre-tension and the needle section 20 automatically presses itself into the recess 19 when both joint bodies 15, 16 are finally aligned along the longitudinal axis 9. If the wiper plate wings 3, 4 are brought from the wringing position 7 into the working position 6, the wiper plate wings 3, 4 move away from the intermediate element 27 and the pre-tension of the spring section 21 on the needle section 20 decreases, thereby causing the needle section 20 to automatically move out of the recess 19.

Two laterally projecting projections 10, 11 are formed from the joint 5, which rest on essentially semicircular sliding surfaces 12, 13 formed from the base 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 the curved sliding surface 12, 13 and the plateau 14. If the joint 5 is aligned at an angle to the longitudinal axis 9 during cleaning work, the projections 10, 11 rest on the circular sections of the sliding surfaces 12, 13. If the joint 5 is now pivoted in the direction of the longitudinal axis 9, the projections 10, 11 on the sliding surfaces 12, 13 move in the direction of the plateau 14, wherein the projections 10, 11 are deformed after reaching the step. This increases the resistance against further pivoting of the joint 5, so that the wiping plate 1 does not fold over during cleaning.

Furthermore, the elements 26 of the second wiping plate wing 4 can be seen. In the wringing position 7, the elements 26 are pivoted in the direction of the joint 5. Furthermore, the projections 28, 29 of the foot pedal 23 can be seen, which are designed as spring tongues and in the working position 6 rest against the underside of the second wiping plate wing 4 with pre-tension. Furthermore, the stop elements 32 can be seen, which increase the contact area between the elements 26 and the joint 5.

Figures 8 and 9 show details of the wiping plate 1 in the wringing position 7. In particular, the stop elements 32 as well as the sliding surfaces 12, 13 and the plateau 14 with the formed step can be seen.

Figure 10 shows the wiping plate 1 in the wringing position 7 in the partial view.

Figure 11 shows the wiper plate 1 in the working position 6, with the area around the foot pedal 23 shown in section. In this position, the holding elements 31 of the foot pedal 23 overlap the elements 26 of the second wiper plate wing 4. The projections 28, 29 of the foot pedal 23 rest against the underside of the elements 26 of the second wiper plate wing 4 with pre-tension.

Figure 12 shows the wiper plate 1 according to Figure 11 , whereby the foot pedal 23 is actuated. As a result, the holding elements 31 are spaced from the second mop plate wing 4 and the second mop plate wing 4 is released for pivoting. At the same time, the projections 28, 29 press against the Underside of the elements 26 of the second mop plate wing 4 and thereby move the second mop plate wing 4 and, via the toothing, also the first mop plate wing 3 out of the working position 6. If the foot pedal 23 is then released, the mop plate wings 3, 4 can no longer lock themselves in place and when the mop plate 1 is lifted, the mop plate wings 3, 4 pivot into the wringing position 7.
