Technical Field

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

Background

Such a mop plate is known, for example, from DE 102012007525 a 1. The mop plate forms part of a mop, wherein the mop has a lever in addition to the mop plate, which lever is connected to the mop plate by a hinge. The mop plate is provided with a mop cover which is releasably fastened to the mop plate in such a way that it can be brought into contact with the floor surface to be cleaned. The mop plate presses the mop sleeve in a planar manner against the floor to be cleaned.

In order to wring out the mop sleeve, the mop plate wings are transferred from the operating position into the wringing position. The wiper sleeve is suspended in the form of a ring from the wiper plate. The mop sleeve suspended from the mop plate can thus be wrung out in a basket-shaped wringing device by pressing in the mop tool. It is also known to press the wiping bushing into a rotatable wringing device, in which the wiping bushing is wrung out by the wringing basket rotating rapidly together with the wiping plate. In both cases, for simple introduction of the wiping device, it is advantageous if the wiping plate with the wiping sleeve is pressed into the wringing device. In the case of a manual wringing device for wringing out a mop plate by pressing in, it is problematic that the hinge can tilt during the pressing in, which reduces the forces to be introduced and deteriorates the implementation result.

Disclosure of Invention

The object of the invention is to provide a mop plate which can be transported to a wringing device in a particularly simple manner.

The object is achieved by the mop plate according to the invention. The wiper blade has a base body, to which a first wiper blade wing, a second wiper blade wing and a hinge are connected in a pivotable manner, wherein the first wiper blade wing and the second wiper blade wing can be pivoted between a working position and a wringing position, wherein a device for locking the hinge is assigned, which device fixes the hinge along a longitudinal axis of the hinge when the first wiper blade wing and the second wiper blade wing are outside the working position, wherein the hinge has a first hinge body and a second hinge body, wherein the first hinge body receives a spring pin which projects through a longitudinal opening which is introduced into the first hinge body, wherein the spring pin has a pin section which is arranged in the longitudinal opening and has a spring section which is arranged in a transverse opening which is open in the direction of the base body, such that the first wiper blade wing and the second wiper blade wing, when pivoted out of the working position into the wringing position, come into contact with the spring section and will return the first wiper blade wing and the second wiper blade wing into contact with the spring section The needle section is pressed through the longitudinal opening in the direction of the recess of the second hinge body.

In order to solve this problem, a device for locking the hinge is provided in the base body, which fixes the hinge along the longitudinal axis when the wiper blade is out of the operating position. In particular, the hinge is fixed along the longitudinal axis by means of a device for locking when the mop plate wing is pivoted out of the operating position into the wringing position. The fastening is also provided according to the invention when the mop plate wing is in the wringing position. This ensures that the hinge can no longer be deflected or tilted during the pressing of the mop plate into the wringing basket. The force introduced into the mop plate over the entire rod can thus be used for the wringing operation. Thereby improving the wringing results.

The joint is preferably designed as a universal joint. The hinge can thus be pivoted together with the lever not only in the longitudinal direction but also in the transverse direction relative to the mop plate.

The hinge preferably has a first hinge body and a second hinge body, wherein the first hinge body is preferably arranged on the base body in a pivotable manner and the second hinge body is arranged on the first hinge body in a pivotable manner, wherein a pivot axis between the first hinge body and the second hinge body is oriented transversely to the pivot axis between the first hinge body and the base body. A universal joint results from this arrangement.

The second mop leaf can have a projecting element which is designed in such a way that it encloses the base body and the hinge associated with it in a U-shaped manner via the element. In such a design, the element is deflected in the direction of the hinge when the wiper blade is deflected and thereby locks the hinge. The element covers the hinge in the region of the main sides of the mop plate, i.e. the front and rear edges. In the case of a pivoted wiper blade wing, the element prevents the lever from being able to pivot in the direction of the main side.

A stop element can be assigned to the element, which stop element points in the direction of the hinge in the wringing position. The stop element can increase the stop area and thus lead to an improved fixing of the hinge.

The first hinge body may receive a pogo pin that protrudes through a longitudinal opening introduced into the first hinge body. The second hinge body may have a void that coincides with the longitudinal opening when the second hinge body is oriented in the direction of the longitudinal axis relative to the first hinge body. This is then the case when the deflection axis is 0 ° or in the range of 0 ° not only in the longitudinal direction but also in the transverse direction.

This design enables the fixation of the hinge bodies when the two hinge bodies are oriented along the longitudinal axis. The longitudinal opening receives a pogo pin, wherein the pogo pin penetrates into the gap when the second hinge body is oriented in the direction of the longitudinal axis with respect to the first hinge body. The two hinge bodies are thereby fixed relative to one another and can no longer be automatically deflected.

The spring pin can have a pin-shaped pin section which is arranged in the bore and has a spring section which is arranged in a further transverse opening which is open in the direction of the base body, so that the two wiper blade wings come into contact with the spring section when the wiper blade is deflected from the operating position into the wringing position and press the spring pin through the longitudinal opening in the direction of the recess of the second hinge body. This ensures that the spring pin penetrates the recess only when the wiper blade is transferred from the operating position into the wringing position.

In the operating position, the spring pins are located, in contrast, only in the longitudinal openings, so that the first hinge body can be pivoted relative to the second hinge body. By the design as a spring section, a prestress can be formed on the spring pin during the deflection, so that a deflection of the wiper blade limb is also possible when the lever is not oriented toward the longitudinal axis. If, after the wiper blade limb has been deflected from the operating position into the wringing position, the lever is oriented toward the longitudinal axis, the spring pin automatically springs into the recess on account of the prestress.

When the wiper blade is transferred from the wringing position into the operating position, the prestress on the spring section is reduced until the spring section is free after the operating position is reached and the needle section is arranged in the recess and the longitudinal opening in a freely movable manner. By the action of gravity, the pogo pins automatically leave the interspace and remain only in the longitudinal openings. The two hinge bodies can then be freely deflected again relative to one another.

The spring section can be assigned an intermediate element which comes into contact with the spring section when the wiper blade limb is transferred from the operating position into the wringing position and brings about: the needle section is pressed through the longitudinal opening into the interspace. In the working position, the intermediate element is preferably spaced apart from the spring section, so that the needle section is automatically removed from the recess and the two hinge bodies are released.

Starting from the hinge, two laterally projecting projections can be formed, which rest on a sliding surface formed by the base body. The projection projects in the direction of the narrow side of the wiper plate and rests on the sliding surface in the region of the free end of the projection. The base body can form a substantially semicircular projection, wherein the outer contour of the semicircular projection forms a sliding surface. The projection is formed by a sliding surface on the upper side of the projection, i.e. on the side of the projection facing away from the base body.

The projections are preferably designed such that they project beyond the sliding surface, so that a step results at each of the two transitions from projection to sliding surface.

During the cleaning operation, the rod is usually pivoted by an angle of between 45 ° and 80 ° relative to the longitudinal axis. In this angular range, the projection rests on a curved sliding surface and the wiper plate can be pivoted relative to the lever.

In particular, during the backward movement of the cleaning appliance, forces can act on the mop plate, which cause the mop plate to fold so that the mop cover no longer lies flat on the floor to be cleaned. This is particularly the case on wiping covers which are only slightly wet and on matt floors. By means of the step in the region of the transition between the curved sliding surface and the projection, a resistance is reacted to the projection, which resistance prevents the mop plate from folding up during the cleaning operation when the mop plate is moved backwards.

Detailed Description

The figure shows a mop plate 1 comprising 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 provided with a hinge 5, here a universal joint, which can be connected to a lever. The

wiper blade wings

3, 4 can be reversibly fixed in the operating position 6. In the operating position 6, the two

wiper blade wings

3, 4 are oriented substantially in one plane. By actuating the foot pedal 23, the

mop wing

3, 4 can be pivoted out of the operating position 6 into the wringing position 7.

The mop plate 1 and the

mop plate wings

3, 4 have an upper side and a lower side forming a wiping surface. The undersides of the first wiper blade wing 3 and the second wiper blade wing 4 move toward one another when the

wiper blade wings

3, 4 are deflected from the operating position 6 into the wringing position 7. In the wringing position 7, the two undersides of the two

mop wings

3, 4 lie opposite one another.

The foot pedal 23 is arranged on the first wiper blade 3 in a pivotable manner and is designed in such a way that the foot pedal 23 fixes the second wiper blade 4 in the operating position 6. The foot pedal 23 is furthermore designed such that the second wiper blade wing 4 is deflected relative to the first wiper blade wing 3 when the foot pedal 23 is actuated.

The foot pedal 23 is connected in an articulated manner to the first wiper blade wing 3, wherein the foot pedal 23 has a free first end which projects from the first wiper blade wing 3 and forms an actuating section of the foot pedal 23. Furthermore, the foot board 23 has a free second end projecting in the direction of the second wiper blade wing 4, which second end forms an interlocking section of the foot board 23.

The foot board 23 has two

projections

28, 29 which are assigned to the interlocking sections. The two

projections

28, 29 are designed as spring elements and are arranged on the underside of the second wiper blade 4 in the operating position 6. Where the two

projections

28, 29 bear with elastic prestress.

The second mop wing 4 has a projecting element 26, which is designed in such a way that the second mop wing 4, together with the element 26, encloses the base body 2 in a U-shaped manner. The foot pedal 23 forms a retaining element 31 which overlaps the element 26 of the second wiper blade leaf 4 and thus, together with the

projections

28, 29, secures the

wiper blades

3, 4 in the operating position 6.

If the foot pedal 23 is actuated, the holding element 31 is spaced apart from the second wiper blade wing 4 and releases the second wiper blade wing 4 for deflection. At the same time, the two

projections

28, 29 press against the underside of the second wiper blade wing 4 and thereby deflect the second wiper blade wing 4 relative to the first wiper blade wing 3 by actuating the foot pedal 23.

The first mop plate wing 3 and the second mop plate wing 4 each have a toothing, wherein the teeth of the toothing engage in one another. The two

wiper blades

3, 4 are thereby simultaneously deflected relative to the base body 2. In the wringing position 7, the two

wiper blade wings

3, 4 are located below the base body 2 or are aligned with the lever, the hinge 5 and the base body 2.

The first mop wing 3, the second mop wing 4 and the foot pedal 23 are positively locked in the operating position 6.

The base body 2, the

mop wings

3, 4 and the hinge 5 are made of injection-moldable plastic. The underside of the

wiper blade wings

3, 4 is provided with a structure in the form of ribs 24. The ribs 24 enable a locally high surface pressure of the wiping sleeve on the ground surface to be cleaned. Thereby improving the purification performance.

The

wiper blade wings

3, 4 are provided with a device 25 for fastening the wiper sleeve. The device comprises in the present design a recess which is provided in the edge region of the narrow sides of the

wiper blade limbs

3, 4 and serves to receive a button of the wiper sleeve. In this way, the mop sleeve is also fixedly connected to the mop plate 1 in the wringing position 7, so that the mop sleeve can be wrung out from the mop plate 1 in the wringing device.

A fastening device 8 for locking the hinge 5 is associated with the base body 2, said fastening device fastening the hinge 5 in the wringing position 7 along a longitudinal axis 9 of the hinge 5.

When the

mop wings

3, 4 are deflected, the projecting element 26 of the second mop wing 4 is deflected in the direction of the hinge 5. The hinge 5 is thereby locked and cannot be pivoted in the direction of the element 26. A stop element 32 is assigned to the element 26, which increases the contact surface between the element 26 and the hinge 5. The element 26 here forms part of the fastening device 8 and defines the mobility of the hinge 5 in a deflection direction pointing in the direction of the main side of the

wiper blade limb

3, 4.

The hinge 5 is designed as a universal joint and has a first hinge body 15 and a second hinge body 16. The first hinge body 15 is arranged on the base body 2 in a pivotable manner. The second hinge body 16 is arranged on the first hinge body 15 in a pivotable manner, wherein a pivot axis between the first hinge body 15 and the second hinge body 16 is oriented transversely to the pivot axis between the first hinge body 15 and the base body 2, so that a universal joint is produced.

In the other part of the fixing device 8, the first hinge body 15 receives a spring pin 17 which projects through a longitudinal opening 18 introduced into the first hinge body 15. The second hinge body 16 has a recess 19 which coincides with the longitudinal opening 18 of the first hinge body 15 when the second hinge body 16 is oriented in the direction of the longitudinal axis 9 relative to the first hinge body 15.

The spring pin 17 has a pin 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 opens out in the direction of the base body 2 and is introduced into the first hinge body 15. When the

wiper blade

3, 4 is deflected from the operating position 6 into the wringing position 7, the

wiper blade

3, 4 comes into contact with the spring section 21 via the 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 hinge body 16. If the hinge 5 is oriented toward the longitudinal axis 9, the pin section 20 is pressed into the recess 19, so that the first hinge body 15 and the second hinge body 16 are fixed toward one another along the longitudinal axis 9. If the two

hinge bodies

15, 16 are not yet completely oriented toward one another, the needle section 20 rests with prestress on the second hinge body 16 and, when the two

hinge bodies

15, 16 are finally oriented along the longitudinal axis 9, the needle section 20 is automatically pressed into the recess 19. If the

mop wings

3, 4 are moved from the wringing position 7 into the operating position 6, the

mop wings

3, 4 are spaced apart from the intermediate element 27 and the prestress of the spring section 21 on the needle section 20 is reduced, whereby the needle section 20 is automatically removed from the recess 19.

Starting from the hinge 5, two laterally projecting

projections

10, 11 are formed, which rest on substantially semicircular sliding

surfaces

12, 13 formed by the base body 2. The sliding surfaces 12, 13 have a projection 14, wherein the projection 14 is designed in such a way that a step is produced at the transition between the curved sliding

surfaces

12, 13 and the projection 14. If the hinge 5 is oriented obliquely to the longitudinal axis 9 during the cleaning operation, the

projections

10, 11 rest on the circular sections of the sliding

surfaces

12, 13. If the hinge 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 cams 14, wherein the

projections

10, 11 are deformed after reaching the step. The resistance against further deflection of the hinge 5 is thereby increased, so that the mop plate 1 does not fold during the cleaning operation.

projections

28, 29 of the foot pedal 23 are visible, which are designed as spring tongues and rest with prestress on the underside of the second wiper blade wing 4 in the operating position 6. Furthermore, a stop element 32 is visible, which increases the contact surface between the element 26 and the hinge 5.

Fig. 8 and 9 show a detail of the mop plate 1 in the wringing position 7. In particular, the stop element 32 can be seen, as well as the sliding

surfaces

12, 13 and the projection 14 comprising the formed step.

Fig. 10 shows a partial view of the mop plate 1 in the wringing position 7.

Fig. 11 shows the mop plate 1 in the operating position 6, wherein the region surrounding the foot pedal 23 is shown in section. In this position, the retaining element 31 of the foot pedal 23 overlaps the element 26 of the second wiper blade wing 4. The

projections

28, 29 of the foot pedal 23 bear with prestress against the underside of the element 26 of the second wiper blade wing 4.

Fig. 12 shows the mop plate 1 according to fig. 11, wherein the foot pedal 23 is actuated. The holding element 31 is thereby spaced apart from the second wiper blade flap 4 and the second wiper blade flap 4 is released for deflection. At the same time, the

projections

28, 29 press against the underside of the element 26 of the second mop wing 4 and thereby move the second mop wing 4 and, via the engagement, also the first mop wing 3 out of the operating position 6. If the foot pedal 23 is subsequently released, the

mop wings

3, 4 can no longer be automatically locked and the

mop wings

3, 4 are deflected into the wringing position 7 when the mop plate 1 is lifted.
