Wiping board

Technical Field

The invention relates to a mop plate having a base body, to which a first mop plate wing and a second mop plate wing are pivotably connected, wherein the mop plate wings can be reversibly secured in a working position by means of a securing device, wherein the securing device has a foot pedal, wherein the securing device is released by actuating the foot pedal, so that the mop plate wings can be pivoted from the working position into a wringing position, wherein the foot pedal is pivotably arranged on the first mop plate wing and the foot pedal secures the second mop plate wing in the working 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 assigned a mop sleeve 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 be able to remove the mop sleeve, it is known to implement the mop plate in a deflectable manner, wherein the mop plate has two mop plate wings which are oriented in a substantially horizontal plane in the operating position. In order to remove the wiping sleeve or to wring out the wiping sleeve, the wiper blade can be transferred into the wringing position. This is done by deflecting the wiper blade wings towards each other.

In order to automatically hold the wiper blade wings in the operating position, it is also known to provide a fixing device which fixes the wiper blade wings in the operating position relative to one another. The fastening device has a foot pedal which is designed in such a way that the fastening of the wiper blade is released by actuating the foot pedal, so that the wiper blade can then be pivoted.

The problem is that the actuation direction of the foot pedal for releasing the fastening corresponds to the deflection direction of the wiper blade wing from the operating position into the wringing position. It is thereby possible for the wiper blade wing to remain in the operating position during the actuation of the foot pedal and to be fixed again in the operating position after the foot pedal has been released. To prevent this, it is known in the prior art to pretension the two wiper blade wings with the aid of spring elements in such a way that the wiper blade wings are automatically deflected into the wringing position. However, it is disadvantageous here that additional construction elements are required and the changeover of the mop wings from the wringing position into the working position can become difficult.

Disclosure of Invention

The object of the present invention is to provide a mop plate which can be produced at low cost and has simple operability.

This object is achieved by the features of claim 1. The dependent claims relate to advantageous embodiments.

In order to solve this object, the foot pedal has a spring mechanism which is designed in such a way that the second wiper blade is deflected relative to the first wiper blade when the foot pedal is actuated. The two wiper wings are thus released from their fastening and are simultaneously pivoted when the foot pedal is actuated, so that the two wiper wings are not immediately locked again when the foot pedal is released.

The fixing of the two wiper blade wings is preferably effected by means of a snap connection. For this purpose, the foot plate, which is arranged so as to be pivotable on the first wiper blade wing, has a section which is interlocked with a further section of the second wiper blade wing. For this purpose, the foot pedal can have a retaining element on the edge assigned to the second wiper blade, which retaining element overlaps and thereby fixes the second wiper blade in the operating position. Alternatively, one or more projections can be provided which, in the operating position, project into a recess which is formed by the second wiper blade wing. When the foot pedal is actuated, the foot pedal is spaced apart from the second wiper blade wing, so that the retaining element is spaced apart from the second wiper blade wing and the second wiper blade wing can be pivoted relative to the foot pedal and thus relative to the first wiper blade.

The foot pedal and the second mop wing are furthermore preferably designed such that the fixing of the two mop plates takes place automatically when the two mop wings are transferred from the wringing position into the operating position. In this design, a section of the second wiper blade wing automatically latches in under the foot pedal, wherein the foot pedal is automatically deflected in this case.

The foot pedal is preferably connected in an articulated manner to the first wiper plate, wherein the foot pedal has a free first end which projects from the first wiper plate and forms an actuating section of the foot pedal, and a second end which projects in the direction of the second wiper plate and forms an interlocking section of the foot pedal.

The mop plate can have an upper side and an underside forming a cleaning surface, wherein the undersides of the first mop plate wing and the second mop plate wing move toward one another when deflected from the operating position into the wringing position. In the operating position, the undersides of the first and second wiper blade wings are oriented substantially in the horizontal plane. The foot pedal is preferably arranged on the upper side of the first wiper blade wing. The foot pedal is designed in the form of a rocker.

At least one projection can be assigned to the foot pedal, which projection is assigned to the interlocking section, wherein the projection is assigned to the underside of the second mop wing in the operating position. Here, two projections may be provided. When the foot pedal is actuated, the projection presses against the underside of the second wiper blade wing. The second mop plate wing is thereby deflected at a small angle relative to the first mop plate wing. It is sufficient that the two wiper wings no longer lock automatically after releasing the foot pedal. The release of the foot pedal from the second wiper blade wing and the lifting of the second wiper blade wing are simultaneously carried out when the foot pedal is actuated. If the mop plate is then spaced apart from the floor to be cleaned, the two mop plate wings are deflected toward one another and the mop sleeve can be wrung out or removed from the mop plate.

The projection can be designed as a spring element. According to a further advantageous embodiment, the projection is designed as a spring tongue. In this design, the projection is designed as a clamping plate with a thin wall thickness. The projection, like the two wiper wings, is preferably made of injection-moldable plastic. In this design, the protruding portion can be deformed when the foot pedal is manipulated, which is accompanied by easier operability.

The foot pedal can have a retaining section which is assigned to the interlocking section, wherein the retaining section is assigned to the upper side of the second mop wing in the operating position. The second mop plate wing is preferably designed such that, in a plan view, it encloses the base body in a U-shaped manner and in this case partially covers the first mop plate wing. By means of this design, two projecting elements are formed on the second mop plate wing, which elements are deflected in the direction of the hinge when the mop plate wing is deflected from the operating position into the wringing position. A retaining section of the foot pedal is assigned to the projecting element, which in the operating position overlaps the element and thereby locks the wiper blade flap. The two wiper blade wings cannot be automatically deflected in this position. If the foot pedal is actuated, the element is moved away from the holding section, so that the second wiper blade is released and can be deflected relative to the foot pedal or the first wiper blade.

The retaining element and the retaining section are preferably selected such that the retaining section automatically snaps onto the element when deflected from the wringing position into the working position by merely pressing the lever and automatically locks in this position. This can be done, for example, by the retaining section coming into contact with an element of the second mop plate wing, wherein the element deflects the foot pedal comprising the retaining section. Once the retaining section overlaps the element, the foot pedal is deflected back and the wiper blade wing is locked in the working position.

The first mop plate wing and the second mop plate wing may each have an engagement section, which engage in one another. This ensures that the wiper blade wings are deflected uniformly.

The first mop wing, the second mop wing and the foot pedal can be interlocked in a form-fitting manner in the operating position.

Detailed Description

The figures show 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 attached in a pivotable manner. A hinge 15, in this case a universal joint, which can be connected to the lever, is associated with the base body 2. The

wiper blade wings

3, 4 can be reversibly fixed in the operating position 6 by means of a fixing device 5. In the operating position 6, the two

wiper blade wings

3, 4 are oriented substantially in one plane. The fastening device 5 has a foot pedal 7, wherein the fastening device 5 is released by actuating the foot pedal 7, so that the

mop wings

3, 4 can be pivoted out of the operating position 6 into the wringing position 8.

The mop plate 1 and the

mop plate wings

3, 4 have an upper side 11 and a lower side 12 forming a wiping surface. The undersides 12 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 8. In the wringing position 8, the two undersides 12 of the two

mop wings

3, 4 lie opposite one another.

The foot pedal 7 is arranged on the first wiper blade 3 in a pivotable manner and is designed in such a way that the foot pedal 7 fixes the second wiper blade 4 in the operating position 6. The foot pedal 7 is also designed in such a way that the second wiper blade 4 is deflected relative to the first wiper blade 3 when the foot pedal 7 is actuated.

A foot pedal 7 is connected in an articulated manner to the first mop plate wing 3, wherein the foot pedal 7 has a free first end 9 which protrudes from the first mop plate 1 and forms an actuating section of the foot pedal 7. Furthermore, the foot board 7 has a free second end 10 projecting in the direction of the second wiper blade wing 4, which second end forms an interlocking section of the foot board 7.

At the free second end 10, the foot pedal 7 has two retaining elements 26 at the end, which are assigned to the locking section. The two holding elements 26 overlap the second wiper blade flap 4 in the operating position 6. At the same time, the projection 13 embodied as a spring tongue rests with elastic prestress against the underside 12 of the second mop wing 4. The projection 13 is also constituted by the foot board 7. The two holding elements 26 and the projections 13 rest above and below the second wiper blade flap 4 in the operating position 6 and clamp it therebetween. The

wiper blade wings

3, 4 are thereby fixed in the operating position 6.

The second mop wing 4 has a projecting element 25, which is designed in such a way that the second mop wing 4, together with the element 25, encloses the base body 2 in a U-shaped manner. When the

wiper blade

3, 4 is deflected, the element 25 is deflected in the direction of the hinge 15. In the operating position 6, the holding element 26 rests on the element 25 on the upper side 11 and thereby locks the

wiper blade wings

3, 4 in the operating position 6.

If the foot pedal 7 is actuated, the holding element 26 is spaced apart from the second wiper blade wing 4 or the element 25 and releases the second wiper blade wing 4 for deflection. At the same time, the two projections 13 press against the underside 12 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 7.

The first wiper blade limb 3 and the second wiper blade limb 4 each have an engagement section 14, which engage in one another. The two

wiper blades

3, 4 are thereby simultaneously deflected relative to the base body 2. In the wringing position 8, the two

wiper blade wings

3, 4 are located below the base body 2 or are aligned with respect to the lever, the hinge 15 and the base body 2.

The first mop wing 3, the second mop wing 4 and the foot pedal 7 are positively locked in the first operating position 6.

The base body 2, the

wiper blade wings

3, 4 and the hinge 15 consist of injection-moldable plastic. The underside 12 of the

wiper blade wings

3, 4 is provided with a structure in the form of ribs 16. The ribs 16 enable a locally high surface pressure of the wiping sleeve on the ground to be cleaned. Thereby improving the purification performance.

The

wiper blade wings

3, 4 are provided with means 17 for fastening the wiper sleeve. In the present design, the means are formed by recesses which are mounted in the edge regions of the narrow sides of the

wiper blade limbs

3, 4 and serve to receive the push buttons of the wiper sleeve. In this way, the mop sleeve is also fixedly connected to the mop plate 1 in the wringing position 8, so that the mop sleeve can be wrung out in the wringing device while being suspended from the mop plate 1.

Fig. 1 shows a front view of a mop plate 1 in a working position 6.

Fig. 2 shows a plan view of the mop plate 1 in the operating position 6.

Fig. 3 shows a bottom view of mop plate 1 in operating position 6. In addition to the ribs 16, a cover 24 is visible in a bottom view, which covers the foot pedal 7 on the underside 12. The foot board 7 is thus protected against undesired intervention through the underside 12.

Fig. 4 shows a side view of the mop plate 1 in the operating position 6. In this side view, the first wiper blade wing 3 including the foot pedal 7 is shown. Fig. 5 shows a further side view of mop plate 1 in operating position 6. In this side view, the second wiper blade wing 4 is shown.

Fig. 6 shows a spatial view of the mop plate 1 in the operating position 6.

Fig. 7 shows a side view of the mop plate 1 in the wringing position 8.

A first wiper blade wing 3 is shown comprising a foot pedal 7. Furthermore, an element 25 of the second mop wing 4 can be seen. In the wringing position, the element 25 is deflected in the direction of the hinge 15.

Fig. 8 shows a front view of the mop plate 1 in the wringing position 8.

Fig. 9 shows the mop plate 1 in the operating position 6, wherein the region surrounding the foot rest 7 is shown in section. In this figure, a projection 13 is visible, which is designed as a spring tongue and rests with prestress on the underside 12 of the second wiper blade wing 4. Furthermore, a retaining element 26 can be seen, which is formed by the foot plate 7 and is placed on the upper side 11 of the second wiper blade wing 4 or on the element 25 and, together with the projection 13, locks the two

wiper blade wings

3, 4. A distance holder 19 is provided on the element 25, which comes into contact with the projection 13 when the

mop plate wings

3, 4 are deflected from the wringing position 8 into the operating position 6. By means of the distance holder 19, the element 25 comes into contact with the projection 13 early on in the deflection. Furthermore, the prestress of the projection 13, which is embodied as a spring tongue, increases, so that the

wiper blade

3, 4 is automatically moved out of the operating position 6 after the foot pedal 7 is actuated.

Fig. 10 shows the mop plate according to fig. 9, in which the foot pedal 7 is actuated. The holding element 26 is spaced apart from the second mop wing 4, so that it is released for deflection. At the same time, the projection 13 presses against the underside 12 of the second mop wing 4 and thereby moves 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 7 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 8 when the mop plate 1 is lifted.
