EP3954843B1 - Washing roller holder for a wash bucket - Google Patents

Description

Technical area

The invention relates to a roll holder for holding washing rolls and placing them on a washing bucket according to the preamble of claim 1.

State of the art

Washing buckets with a holder for washing rolls on which washing and joint boards as well as sponges or the like can be stripped or rolled off in order to lead excess water back into the washing bucket are already known in a variety of shapes and designs.

In this context, attention is drawn to the DE 298 03 795 U1 referred. It discloses a roll holder with a receiving bearing for receiving washing rolls and placing them on a washing bucket, having a receiving side and an attachment side, the receiving side comprising a receiving wall which has the receiving bearing for rotatably receiving the washing rolls, and wherein the attachment side comprises an attachment groove, which allows the respective roller holder to be placed on the edge of a washing bucket according to the tongue and groove principle, with the attachment groove on the attachment side being U-shaped in cross section.

The EP 0 910 982 A1 , the DE 78 09 226 U1 and the DE 201 02 362 U1 reveal similar constructions to that DE 298 03 795 U1 .

In this regard, for example, DE 20 2011 052 462 U1 to call. A washing bucket, in particular a tile washing bucket, is disclosed there, which has roll holders on two opposite washing bucket walls, which are used to hold washing rolls.

Washing rolls are also known, for example from EP 1 230 988 B1 . A roller for wiping a sponge board is disclosed there. This roll has so-called stub axles, which are suitable for rotatably holding the washing rolls in roll holders on both sides.

Washing buckets for tiler use are usually rectangular and not round like conventional buckets, which enables the inclusion of scraper and/or unrolling devices. The respective corners of these washing buckets are usually rounded.

A disadvantage of the present prior art is that excess water regularly runs over the edge of the washing bucket when sponges, washboards or the like are rolled on the aforementioned washing rollers. This leads to unnecessary wiping work and puts into perspective the advantage of rolling or stripping the washing tools on the washing rolls.

Furthermore, receiving systems for washing rolls that are permanently connected to the washing bucket are inflexible with regard to the respective applications. Such fixed roller holders also make it more difficult to clean the washing buckets, since the washing rolls first have to be separated from the washing bucket's receiving device, which is a laborious process.

Other holding systems for washing rolls also have the disadvantage that they do not hold the edges of the washing bucket firmly enough and when they are unrolled Retaining systems on the edges of the washing buckets tend to slip, making it difficult to unroll or wipe off.

Task of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, a washing roll holder should be provided which prevents excess unrolled or stripped washing water from getting over the edge of the washing bucket and thus not flowing into the washing bucket. Furthermore, the washing roll holder should be flexible in use and can be attached to standard washing buckets. The washing roll holder should be able to be connected to the washing bucket in a non-slip manner without there being a firm, irreversible connection, so that the washing rolls together with the washing roll holder can be easily removed from the washing bucket at any time.

Solution to the task

The features according to claim 1 lead to the solution of the problem.

Advantageous embodiments are described in the subclaims.

Roll holders according to the invention are used to hold washing rolls and place them on a washing bucket. For this purpose, a pair is required, which consists of two roller holders that are identically mirrored to one another.

These roller holders according to the invention preferably consist of a suitable plastic, but can also consist of metal or another suitable material or another suitable mixture of materials.

The roll holders according to the invention each have a receiving side and an attachment side.

The receiving side is used to rotatably accommodate washing rolls and advantageously enables the reliable drainage of excess water via a drainage channel that is also included on the receiving side.

Furthermore, the receiving side includes a receiving wall, which in turn includes receiving bearings. Washing rolls are rotatably accommodated via these receiving bearings, so-called stub axles of the washing rolls being able to be clipped into the receiving bearings in a simple manner. The washing rolls are thereby reliably kept rotatable in the mounting bearings. The washing rolls can also be removed from the storage areas just as easily.

The drainage channel is delimited on the one hand by the receiving wall and on the other hand by a rear side of an attachment groove, the attachment groove being U-shaped in cross section on the attachment side.

On the receiving side, the back of the attachment groove also includes a rounded drain edge, which directs stripped water into the drain channel. The back of the attachment groove is surrounded by a frame a few millimeters high on the receiving side and there to an inside, an outside and a washing bucket edge side. This frame directs the stripped water that runs over the washing rollers or splashes over the drain edge into the drain channel and prevents water from running over the edge of the washing bucket.

The drainage channel is J-shaped and has two drains, a first drain and a second drain. The first drain is arranged on the inside, the second drain is arranged on the washing bucket edge side.

The attachment side has the attachment groove. The attachment groove is also J-shaped, with a U-shaped groove being formed in cross section. The attachment groove advantageously allows the respective roller receptacles to be placed on the edges of a washing bucket according to the tongue and groove principle. The mirrored pair of roller holders is placed on the edges of the washing bucket in accordance with the J-shaped shape of the attachment groove at the corners of the washing bucket. This has the advantage that the roll holders can slip around on the edges of the washing bucket, but remain there without slipping thanks to the J-shaped shape and the placement in the corners of the washing bucket.

In some exemplary embodiments, the attachment groove also has retaining lamellas on its inside, which provide additional support on the edge of the washing bucket. These slats can be present in different numbers and designs.

The receiving wall, which is arranged on the inside of the receiving side of the roll holder, is trapezoidal. A front side edge is longer than a rear side edge, which is why an upper edge slopes downwards in relation to the drain channel in the direction of the washing bucket edge side.

The receiving wall includes one or more receiving bearings. The upper edge of the receiving wall, which slopes towards the side of the washing bucket edge, is broken through by one, preferably two or three receiving bearings.

This sloping course of the upper edge advantageously leads to the washing rolls received by the receiving wall or by the receiving bearings being arranged at a sloping height from one another to the drain channel or a washing bucket base. This makes stripping easier of the washing tools and the targeted collection of excess water are enormous.

The receiving camps in turn include horseshoe-shaped bearing reinforcements. These bearing reinforcements have two thickenings, each arranged at an open end and opposite one another. These thickenings extend into the open area and allow the axle stubs of the washing rollers to be securely clipped in, so that they are stored in the receiving bearing so that they can rotate and at the same time are secured against slipping out.

Furthermore, the receiving wall includes a reinforcement on the side facing the drainage channel. The reinforcement is adapted to the shape of the receiving wall, with recesses being provided for the receiving bearings, for example. The reinforcement is plate-shaped and preferably consists of a metal or a suitable plastic. In preferred embodiments, the reinforcement is connected to the receiving wall using screws, rivets and/or a suitable adhesive to reinforce the receiving wall via holes included therein. The reinforcements can be arranged on the roller holders and removed from them as required. This leads to the advantage that the roller holders are more resilient and more durable.

Embodiment example

In the Figures 1, 2 and 3 is a first roll recording 1 and in the Figures 4, 5 and 6 a second roll holder 2 shown. The first roller holder 1 and the second roller holder 2 form a matching pair. A pair of roller holders is each mirrored and designed to be identical.

The matching pair of roll holders 1 and roll holders 2 allows two washing rolls to be rotatably accommodated and their positioning across a washing bucket.

In the Figures 7, 8 and 9 is a third roll holder 3 and in the Figures 10, 11 and 12 a fourth roll holder 4 is shown. The third roller holder 3 and the fourth roller holder 4 also form a mirrored, identical pair. This pair represents a further embodiment of the invention.

The matching pair of roll holders 3 and roll holders 4 allows three washing rolls to be rotatably accommodated and their positioning across a washing bucket.

Since the first roll holder 1 and the second roll holder 2 are designed to be identical in a mirrored manner, only the first roll holder 1 will be described below, since the same applies to the roll holder 2 in a mirrored sense.

The first roll holder 1 has a receiving side 5 and an attachment side 6. Furthermore, the roll holder 1, like all other roll holders, also has an inside 22, an outside 23 and a washing bucket edge side 24.

The receiving side 5 is the side of the roll holder 1 on which the washing rolls are picked up and water is led back through a drainage channel 7 into a washing bucket.

A receiving wall 8 is included to accommodate washing rolls or their axle stubs. In the present exemplary embodiment, this receiving wall 8 has a first receiving bearing 9.1 and a second receiving bearing 9.2. The first exception bearing 9.1 and the second exception bearing 9.2 each form a circular recess in the receiving wall 8 that is open towards the top.

The receiving bearings 9.1, 9.2, 9.3 have a horseshoe-shaped bearing reinforcement 13. This bearing reinforcement 13 is wider than the receiving wall 8, the bearing reinforcement 13 being flush with the receiving wall 8 on the side of the receiving wall 8 that is directed in the direction of the drainage channel 7 and correspondingly protruding by a few millimeters on the opposite side of the receiving wall 8. This increases the contact surface of the receiving bearings 9.1, 9.2, 9.3.

Furthermore, the receiving wall 8 has a hole 20 in its central region. This hole 20 serves to arrange a plate-shaped reinforcement made of a suitable plastic or metal on the receiving wall 8. The reinforcement has recesses for the receiving bearings 9.1, 9.2, 9.3 and is arranged on the side of the receiving wall 8 on which the drainage channel 7 runs. For this purpose, a suitable fastening means, for example a screw or a rivet, is passed through the hole 20 from the side opposite the drainage channel 7 and connected to the reinforcement. This reinforcement is not shown in the figures.

The receiving bearings 9.1, 9.2 are arranged from one another on the receiving wall 8 in such a way that two washing rollers running parallel to one another can be rotatably received on their stub axles.

An upper edge 14 of the receiving wall 8, which is broken through by the two receiving bearings 9.1, 9.2, runs slopingly towards the drainage channel 7 from the area in which the receiving bearing 9.1 is arranged towards the area in which the receiving bearing 9.2 is arranged, i.e. in the direction of Washing bucket edge side 24. This means that the receiving bearing 9.1 is at a greater distance from the drainage channel 7 than the receiving bearing 9.2. The receiving wall 8 is therefore trapezoidal in shape, since a front side edge 15 is longer than a rear side edge 16.

As a result, a washing roll that is received by the receiving bearings 9.1 is further away from the drain trough 7 or a washing bucket bottom than the second washing roll, which is arranged somewhat deeper in the receiving bearings 9.2.

The corners of the receiving wall 8, i.e. the areas in which the front side edge 15 merges into the upper edge 14 and the upper edge 14 merges into the rear side edge 16, are rounded.

The drainage channel 7 is also arranged on the receiving side 5 of the first roller holder 1. The drainage channel 7 is designed as a J-shaped channel. The drainage channel 7 has a drain at its respective ends. A first drain 17 and a second drain 18. The first drain 17 is arranged on the inside 22. The second drain 18 is arranged on the washing bucket edge side 24. The first drain 17 and the second drain 18 are separated from each other by the receiving wall 8. By J-shaped it is meant that the first drain 17 is on the inside 22 in one Angle of 90 degrees to the second drain 18 on the washing bucket edge side 24 is aligned.

The drain groove 7 is delimited on the one hand by the receiving wall 8 and on the other hand by the back of an attachment groove 12. The attachment groove 12 is J-shaped on the attachment side 6, just like the drainage channel 7, and its cross section is U-shaped, as in, for example Figure 3 , a view of the attachment side 6 of the roll holder 1 according to the invention can be clearly seen.

The rear attachment groove 12 has a rounded drain edge 10 on the receiving side 5, which, in conjunction with a circumferential frame 11, ensures that water drains into the drain channel 7 in a targeted manner. The circumferential frame 11 is a few millimeters high and delimits the attachment groove 12 on the receiving side 5 and there on the sides that face away from the drainage channel 7, namely on the inside 22, the outside 23 and the washing bucket edge side 24. The frame 11 nestles Curved and rounded on both sides, it adjoins the drainage channel 7 before merging into it.

The attachment side 6 is opposite the receiving side 5. The attachment side 6 of the first roller holder 1 according to the invention is, for example, in Figure 3 visible. The attachment side 6 includes the attachment groove 12 and a rear bottom 19 of the drainage channel 7 running on the receiving side 5. The attachment groove 12 is also J-shaped, with a U-shaped cross-sectional groove being formed. This shape of the attachment groove 12 allows the roller holder 1 according to the invention to be placed on the edge and in a corner area of a washing bucket. The slip-on groove 12 accommodates part of the upper edge of a washing bucket using the tongue and groove principle. Due to the J-shaped shape, the first roll holder 1 according to the invention can only be placed in the area of a rounded corner of a washing bucket. The second roll recording 2 of the pair, which is mirrored and identical to the first roll holder 1, fits accordingly on an opposite corner of one side of a washing bucket. The respective inner sides 22 or the respective receiving wall 8 of the pair of the two roller holders 1 and 2 face opposite one another when placed as intended.

In the Figures 8 to 12 the pair of the third roller holder 3 and the fourth roller holder 4 is shown.

The third roller holder 3 and the fourth roller holder 4 are also mirrored and identical, which is why the third roller holder 3 will be described below, since the same applies to the fourth roller holder 4 in a mirrored sense. The third roller holder 3 and the fourth roller holder 4 also form a matching pair.

The pair of the third roll holder 3 and the fourth roll holder 4 differ from the pair of the first roll holder 1 and the second roll holder 2 only in that, in addition to a first and a second washing roll, a further third washing roll can be rotatably accommodated.

For this purpose, the third roller receptacle 3 and the fourth roller receptacle 4, only the third roller receptacle 3 will be described below due to the mirrored identity to the fourth roller receptacle 4, have an elongated shape compared to the pair of the two roller receptacles 1 and 2.

A receiving wall 8.1 is also trapezoidal. In the present exemplary embodiment, this receiving wall 8.1 has the first receiving bearing 9.1, the second receiving bearing 9.2 and a third receiving bearing 9.3, the third receiving bearing 9.3 being designed identically to the other two receiving bearings 9.1 and 9.2 and also having a correspondingly arranged bearing reinforcement 13. Here too the receiving bearings 9.1, 9.2, 9.3 interrupt an upper edge 14.1. In the present exemplary embodiment, the receiving bearings 9.1, 9.2, 9.3 are arranged at the same distance from one another on the receiving wall 8.1 so that three washing rolls can be accommodated parallel to one another in the receiving bearings 9.1, 9.2, 9.3.

In order to have enough space for the third washing roll accommodated in this way, the receiving wall 8.2 is designed to be longer or more plugged in compared to the receiving wall 8.1. This means that the upper edge 14.1 of the receiving wall 8.1 of the roller receptacles 3 and 4 is longer than the upper edge 14 of the receiving wall 8 of the reel receptacles 1 and 2. In accordance with this extension, the entire third reel receptacle 3 and fourth reel receptacle 4 is also designed to be extended. All other features correspond to the pair of first and second roller holders 1 and 2 that have already been described.

Of course, the third roller holder 3 and the fourth roller holder 4 can also be reinforced with a plate-shaped reinforcement. This is designed to correspond to the receiving wall 8.1 and is also arranged on the side that is directed towards a drainage channel 7.1. For this purpose, two holes 20 are included on the receiving wall 8.1. An arrangement in connection with the two bores 20 is also carried out here using a suitable fastening means, for example rivets, screws, and if necessary additionally or solely by gluing.

The trapezoidal design of the receiving wall 8.1 also means that the distance between the receiving bearings 9.1, 9.2 and 9.3 to the drainage channel 7.1 or a washing bucket bottom is reduced. The distance between the receiving camp 9.1 and the drainage channel 7.1 is therefore the largest. The distance between the receiving camp 9.2 and the drainage channel 7.1 is the second largest and the distance between the receiving warehouse 9.3 and the drainage channel 7.1 is the third largest, i.e. the smallest.

Referring to the Figures 1 to 12 The functionality of the roller holders 1, 2, 3, 4 according to the invention is explained as follows:
So that washing rolls can be arranged on an ordinary washing bucket, which is used in particular in the activities of a tiler, without them being firmly and irreversibly connected there, roll holders 1, 2, 3, 4 according to the invention are used. For this purpose, a pair of the roll holders according to the invention is necessary. Through the j-shaped attachment grooves 12 which are arranged on the respective attachment sides 6, the roller holders 1, 2, 3, 4 can be placed on the edge of a washing bucket in the area of the corners.

The pair of roll holders 1, 2 or 3, 4 are attached to the corners of the washing buckets, so that the respective pair of roll holders 1, 2 or 3, 4 lie opposite each other, i.e. the receiving walls 8.1 or 8.2 face each other.

The J-shaped shape of the attachment grooves 12 ensures that the roller holders 1, 2, 3, 4 cannot slip on the edge of the washing bucket. At the same time, the pair of roller holders 1, 2 or 3, 4 arranged in each case can be easily removed from the washing bucket. To do this, the pair of roll holders 1, 2 or 3, 4 are pulled off the edge of the washing bucket together with the washing rolls arranged between them, or without the washing rolls.

The washing rolls are inserted into the opposite receiving bearings 9.1, 9.2 and possibly 9.3, with the axle stubs of the washing rolls being inserted from above, i.e. from the side of the upper edge 14, 14.1, into the receiving bearings 9.1, 9.2 and possibly 9.3 and their bearing reinforcement 13 be clipped in. For this purpose, the bearing reinforcement 13 includes two opposite thickenings 21, which are in the receiving area, which contains the axle stub of the washing rolls in the receiving bearings 9.1, 9.2, 9.3, reach them and hold them there.

After the washing rolls have been clipped into the receiving bearings 9.1, 9.2 and possibly 9.3, they are rotatably mounted there. If necessary, the washing rolls can also be removed from the storage bearings 9.1, 9.2 and 9.3 and exchanged or replaced.

Due to the trapezoidal shape of the receiving wall 8, 8.1, the washing rollers are arranged sloping towards one another. This makes it easier to unroll or wipe off the sponge board or washing tool. Because the washing rolls are arranged within the washing bucket by the roll holders 1, 2, 3, 4 according to the invention, the stripped washing water is reliably returned to the washing bucket.

Excess water cannot get over the edge of the washing bucket, since the drainage channel 7, 7.1 is arranged below the edge of the washing bucket if the roller holders 1, 2, 3, 4 have been placed on the washing bucket in the correct manner. The fact that water does not get over the edge of the washing bucket during the wiping process, but is led over the drain edge 10 into the drain channel 7, 7.1, is also made possible by the surrounding frame 11. This frame 11 therefore represents additional overflow protection.

Although only two preferred embodiments of the invention have been described and illustrated, it is obvious that those skilled in the art can add numerous modifications without departing from the scope of the invention, which is defined by the claims. In particular, a further receiving bearing can be included by extending the roll holders, so that a fourth washing roll could also be accommodated. <b>Reference symbol list</b> 1 first role recording 2 second roll recording 3 third roll recording 4 fourth roll recording 5 Recording page 6 Attachment side 7, 7.1 gutter 8, 8.1 Recording wall 9.1, 9.2, 9.3 Reception camp 10 drain edge 11 Frame 12 Attachment groove 13 Bearing reinforcement 14, 14.1 Top edge 15 front side edge 16 rear side edge 17 first drain 18 second drain 19 Floor 20 drilling 21 thickening 22 inside 23 outside 24 Washing bucket edge side
