Abstract

A cleaning unit for basins which may contain liquid in the base region, especially for WC bowls. It consists of a sleeve-shaped cleaning part (2), designed to be disposable and flushed away, on which there is a cleaning head (4) and a support and operating part to guide it. The sleeve-shaped cleaning part (2) is dimensioned and designed in such a way that the inserted holding and operating part (1) cannot come in contact with accumulated dirt and in particular cannot touch the waste water at the bottom of the basin.

Description

R e i n i g u n g s e t

The present invention relates to ^• a cleaning device for basins that may contain liquid in Bodeπbereich, particularly for toilet bowls gem. the preamble of claim 1.

Cleaning devices for toilet bowls, but also for other bowls, which can have liquid in the floor area, are known in various embodiments. Most common is the permanently mounted on a stielformigen handle toilet brush whose cleaning head is made of natural or synthetic bristles on the entire circumference or only partially applied to the lower end of the stalk ^'. The shape of the brush head can be designed very differently.

However, all of these toilet brushes have decisive hygienic disadvantages. On the one hand, the brush head comes into contact with the dirt adhering to the toilet bowl, which experience shows that even when the brush is subsequently cleaned, it deposits on the bristles and handle and, in addition to the unsavory and unsanitary impression, also causes an unpleasant odor. On the other hand, it cannot always be avoided that water drips from the brush head when the toilet brush is removed from the toilet bowl. Both this dripping water and the still moist and possibly dirty brush as well as the containers, drip trays and the like that are usually used for storage are to be regarded as potential carriers of bacteria and other germs. For these reasons, the use of conventional toilet brushes is to be regarded as unsanitary, which means that the toilet brush is used by the toilet user is often reluctant or not used at all and the toilet bowl is left to the next user uncleaned. As an alternative, chemical cleaning agents are used that have only a low cleaning effect, but are a burden for the sewage treatment plant.

To avoid the aforementioned disadvantages of conventional toilet cleaning brushes, various toilet cleaning devices have recently been proposed in which the hygiene problem is apparently to be solved by a cleaning head made of cellulose or the like attached to the bottom part designed as pliers, plate or the like Ren end of a handle-like holder by clamping, putting on or the like .. and released after a single use without touching by hand by a mechanism and can be washed away in the toilet bowl, the holder being used again. Such constructions are described, for example, in British Patent 15 32 457, British Application 21 07 973 A, German Utility Models 76 25 294, 82 19086 and 1993 157.

Some of these utility models mentioned are discussed and criticized in detail in the utility model GM 82 19 086. Attention is drawn to the problem of the tight fit of the cleaning part on the holding and operating rod (called "holder" or "handle") and to the defects in the technical design. The cleaning device according to GM 82 19 086 consists of a holding and operating rod (called "holding and operating handle") and a sleeve-shaped cleaning part intended for single use (called "cleaning agent"), which is referred to as the "cleaning head" lower end of the holding and operating rod is pushed on, this cleaning head consisting of two hinged plates. After use, the cleaning part is removed by opening one of the two plates by means of a displaceable linkage (also called "operating lever") attached to the holding and operating rod. grazes or tears open.

With such a cleaning device, however, neither the problem of hygiene nor its technical handling are decisively improved. Since the sleeve-shaped cleaning part only covers the lower end of the holding and operating rod and is pocket-shaped, it swells and expands when handled in water and can come off in an uncontrolled manner despite the projections provided on the outside of the plates. This does not guarantee a reliable fit of the cleaning part. If, on the other hand, the cleaning part is not completely soaked, but only moistened, as can occur, for example, when cleaning flat-rinsing toilets, there is a risk during the wiping process that the cleaning part will stick to one of the two plates. If, after the cleaning process, a new cleaning part is to be pushed onto the wetted plates of the holding and operating rod, the cleaning part, since it sticks to the wetted plates, can only be pushed on with the help of the second hand, which is important for the User is an extremely unhygienic and uncomfortable process because touching the ^• plates wetted with dirty water cannot be avoided.

So that the unfolding of one of the two plates at the lower end of the holding and operating rod also works safely, the plates must not deform significantly, so they cannot be flexible. This means that certain areas of the toilet bowl cannot be cleaned at all, or cannot be cleaned conveniently and effectively, e.g. the area of the upper rinsing rim, the bottom of the odor trap or generally strongly curved surfaces.

Since the reusable holding and operating rod itself is not protected against contamination or wetting with dirty water, it cannot be completely avoided when it is used that the lower end of the holding and operating rod comes into contact with a possibly dirty part of the toilet bowl during the cleaning process or is wetted with dirty water by the necessary immersion in the area under water and drips when removed.

This reusable holding and operating stick, which is to be kept after use, is therefore to be regarded as a potential carrier of bacteria and other germs like the conventional toilet brushes and is to be regarded as unsanitary. The cleaning device according to GM 82 19 086 is therefore not an improvement since it is to be regarded as inadequate both in terms of hygiene and handling.

The present invention is therefore based on the object of developing a cleaning device for basins which can contain liquid in the floor area, in particular for toilet bowls, in such a way that the hygienic and technical disadvantages of conventional cleaning brushes and also more recent cleaning devices with disposable cleaning heads are avoided, wherein an easy and safe to use device is to be created, which the user can use without danger of coming into contact with dirt or moisture, directly and without complex constructions.

This object is achieved with a cleaning device with the features of patent claim 1. Advantageous further developments result from the subclaims.

The cleaning device according to the invention accordingly consists of a holding and operating part made of metal, wood or plastic and a cleaning part pushed onto it, intended only for single use, which consists of a sleeve part and a cleaning head that is firmly and preferably liquid-tightly connected to it. The cleaning head can be used as a brush made of known materials such as natural, plastic or paper bristles or made of paper or wood wool, as a sponge, preferably made of foam or other plastics, as a tampon made of cellulose, cotton wool, cleaning wool or the like or as a scraper made of rubber, plastic, paper, foam, cardboard or cellulose.

The sleeve part can be made of paper, cellulose or textile fabric, which may have been treated with chemicals, solutions or the like to increase the liquid resistance, but also consist of a metal or plastic film. 0

The sleeve part is designed in the area of the greatest possible immersion depth as a protective zone which is designed in such a way that it either only allows moisture to penetrate to a small extent or at least for a limited time. The protection zone may be in a bottom and a lateral protection zone are divided that may sstehen b-from the same or from different materials that are impervious to liquids during use time is preferably ^'at least. Possible materials are:. Plastic or metal foil 0 or paper, pulp or textile fabrics, chemicals which, if necessary, with Chemi¬, varnishes, waxes, resins, ^"oils, paraffins, fats, Lösun¬ gen, bituminous materials, adhesives or glues are treated .

25 The lower protection zone can also consist of elastic putty and may have rubber or plastic inserts.

The lateral protection zone can extend over the entire length of the sleeve part. If it does not reach the upper end of the sleeve part, it must be at least longer than the greatest possible immersion depth in the toilet bowl. .

The lower and the lateral protection zone can be in a ,,. Be made. The length of the sleeve part is preferably such that it protects the holding and operating part from contact with a part of the toilet bowl, for example also the edge of the bowl, even at full immersion depth.

The protective effect of the sleeve part or the lateral and lower protection zone ensures that the reusable holding and operating part is protected against the ingress of moisture, dirt or contact with part of the toilet bowl and thus remains clean. At the end of the cleaning process, the cleaning part-1 is either manually

• Or removed from the holding and operating section by a scraper and washed away in the toilet bowl. The still dry

The holding and operating part can now be removed drip-free from the area of the toilet bowl and kept in a ^" hygienically perfect condition for reuse.

If the cleaning device is designed without a scraper device, the length of the sleeve part should preferably be dimensioned such that it extends approximately a hand's width beyond the pool edge at the greatest possible immersion depth, so that it is ensured that it is handled in the clean area after use and by the holding and operating part can be stripped.

In order to prevent accidental detachment of the pushed-on cleaning part from the operating part, there is a clamping device or a friction-based holding device, which acts as a cone ring or., On this part in the area in which the upper edge of the sleeve part comes to lie when pushed open Wedge can be formed from rubber, foam or other known materials, provided that the friction between the sleeve part and the operating part does not already offer a secure hold.

The sleeve part is designed in terms of material and dimensions so that it has the stiffness necessary for handling when dry. possesses the flexibility required to pass the odor trap curvature of the toilet bowl. It can be designed with a small cross section and thin wall thickness. In order to increase the rigidity required for handling, the sleeve part can be equipped with stiffeners, which can consist, for example, of adhesives, glues or other suitable materials if they are not achieved by material deformation or material reinforcements.

In order to ensure that the cleaning part is removed within a single rinsing process, holes are provided above the largest possible immersion area in the sleeve part, which allow water to penetrate more easily when flushing away and thereby accelerate the submersion of the cleaning part.

The stripping device can lie inside or outside the holding and operating part. If it lies within the holding and operating part, it is expediently designed as a tube and the stripping device as a rod, which protrudes at the upper end of the tube by approximately the sleeve length and is preferably connected to the tube by means of a return spring. In order to strip off the cleaning part, the rod is then pushed down through the pipe so that it protrudes from the lower end of the pipe and pulls the cleaning part off the pipe until it falls into the toilet bowl.

If the stripping device is outside the holding and operating part, it can e.g. are designed as a scraper ring which is pushed over the lengthwise split holding and operating part, as will be explained in detail later using an exemplary embodiment.

The cleaning device according to the invention offers over the known cleaning ^{'ungsgeräten} toilet bowl following advantages: ^■ It enables reliable and hygienic handling what one of the previously known and commonly used Reinigungs¬ devices can not be said with certainty.

5 The reusable holding and operating part remains throughout the Reiπigungsvorganges by the sleeve part in trocke¬ NEM and sanitary condition and can no Herab¬ drops of dirty water from the area of the toilet bowl heraus¬ taken and without drip tray easily and hygienically harmless ^• ® should be kept on loan since it is not a potential source of infection like the usual toilet brushes or other known toilet cleaning devices.

Through the scraping and the sufficient long-dimensioning ^'* * ne sleeve portion ensures that the user during Abstrei¬ fen of the cleaning member after use is not in contact with the soiled Reiπigungskopf or may ver¬ soiled area of the sleeve member occurs. Additional advantages can be seen in the fact that, in the present invention, the pushing of the cleaning part onto the holding and operating part can be done easily, safely and hygienically, and premature loosening or tearing of the cleaning part from the holding and operating part, in contrast to other known ones WC cleaning devices with disposable cleaning agents are not possible, 5 since the sleeve part has a secure fit on the holding and operating part due to its length.

In addition, the space required for storing both the holding and operating part and the stock of disposable cleaning parts is very small due to the narrow shape of the device, and the disposable cleaning parts can be stored in commercially available packaging boxes.

As a result of the perfect separation between clean re-ver

35 reversible holding and operating part and the disposable cleaning part 1, the cleaning device is to be handled hygienically, so that greater readiness for use and, consequently, greater cleanliness in toilet bowls can be expected.

_c The cleaning device according to the invention is particularly suitable for immediate use. Since dirt can be easily removed when wet, the cleaning part need not have a high strength and is therefore particularly suitable for washing away. 0

FIG. 24 shows a side view of a storage container with bundled and laterally held cleaning parts.

In Figs. 1 to 3 the basic structure of the cleaning device according to the invention and its application is shown. It consists of a holding and operating part 1 which is rod-shaped in the broadest sense and a cleaning part 2 which, cf. Fig. 2, is pushed onto the holding and operating part 1. The dimensions of these parts are chosen so that cleaning of the water-covered floor of the basin to be cleaned is also possible, as shown in FIG. 3 with the aid of a toilet bowl shown in section.

In the interest of clarity and understanding, the respective holding and operating part is denoted in the following by 1 but with the addition of different letters a or b, depending on the design, as are the cleaning part 2 with its parts sleeve part 3 and cleaning head 4, and according to the different fundamentally different designs.

Using the figures 4 to 7, the structural design of a cleaning device is explained in a flat design. As is basically the case with FIGS. 1 and 2, from a holding and operating part 1a, over which the cleaning part 2a, consisting of a casing-like sleeve part 3a and a cleaning head 4a, is pushed. The holding and operating part 1a has a flat cross section, which can be rectangular, lenticular or oval, for example.

The case-like sleeve part 3a consists of paper, e.g. from crepe paper or waste paper, it can be made in one or more layers by folding once (lengthways or crosswise) from a single piece (similar to coffee filter paper).

The edges 7 to be closed are glued or pressed.

The lower 5 and side 6 protection zone is achieved in the simplest case of the options listed by plastic coating.

The aim is to use materials which can be ^degraded in sewage treatment plants, such as papers with degradable impregnations or the like. The connection of the edges 7 is also watertight in the area of the lower 5 and 6 lateral protection zones.

The cleaning head 4a applied to the lower end of the sleeve part 3a consists of cellulose, paper or other degradable wiping material.

The length of the lateral protection zone 6 must correspond at least to the maximum immersion depth 8 of the cleaning device in the water area of the various types of toilet bowl. If it is necessary or cheap for manufacturing reasons, it can also extend over the entire length of the sleeve part 3a. Above the greatest possible immersion depth 8, the sleeve part 3a is provided with holes 9.

The length of the sleeve part 3a is preferably such that, even with the greatest possible immersion depth, the holding and operating part 1a is in contact with part of the toilet bowl, for example the pool edge, protects, s. Fig. 3.

The inside width of the sleeve part 3a is dimensioned such that an easy pushing and pulling onto or from the holding and operating part 1a is ensured over the entire length; it can remain the same or decrease from top to bottom.

The sleeve part 3a has a lateral edge on which the entire cleaning part 2a may be held and, by way of example, a plurality of cleaning parts 2a may also be packaged by means of lateral adhesive, etc. It is preferably so wide that the cleaning part 2a is light can be handled.

Furthermore, this edge 7 can also be provided with holes 9, which make it possible to store the cleaning parts 2a on pins, hooks or the like ready for use, such as e.g. can be seen from Fig. 11.

FIGS. 24 to 26 show a further advantageous embodiment of the cleaning device according to the invention, which is particularly simple to manufacture and operate in this case. The sleeve parts (3a) are folded during production so that the adhesive seam comes to lie in the middle area and the sleeve parts (3a) have no glued or pressed edges. The individual cleaning parts (2a) are combined into a bundle by an adhesive strip (30) attached to the side, which is fastened as a whole to the storage housing (31). The removal of a cleaning member (2a) is carried out by inserting the holding and operating rod (1) and removal of the cleaning ^'part (2a) of the adhesive tape (30).

As can be seen from FIG. 8, the holding and operating part 1a is slotted on its broad side lengthwise almost to the lower end, so that two strips 11 are formed which are spaced from one another and are connected only in the lower area. gene.

A flexible design of the lower end 12 of the holding and operating part 1a is advantageous in order to facilitate the cleaning of the curved parts of the toilet bowl. The upper end of the two strips 11 is summarized by an operating handle 13, which is expediently attached at an angle from the plane of the two strips 11.

The pair of strips 11 consists of elastic plastic and is preformed so that the distance between the two strips 11 increases from the bottom up to a maximum 14, which corresponds to the clear sleeve cross-section, and then decreases again up to the handle 13.

Above the two strips 11 there is a sliding body 15 which can be moved in the longitudinal direction and which has two openings separated by a web 16, into which the two strips 11 fit with the required tolerance. The width of the web 16 corresponds to the minimum distance between the two strips 11.

Before a cleaning process, the sliding body 15, which has the function of a scraper device, is located above the maximum distance 14 of the conductors 11 and is thereby prevented from sliding down.

If you want to push a cleaning part 2a onto the holding and operating part 1a, you press the strips 11 together a little by pushing the sliding body 15 down a little over the maximum 14 of the strip spacing. The holding and operating part 1a can now be inserted into one of the expediently suspended cleaning parts 2a, cf. for example Fig. 11.

If the sliding body 15 is pushed up again, the strips 11 spread outwards again, as a result of which the sleeve part 3a is held by friction on the holding and operating part 1a (see FIGS. 8, 10, 11). The cleaning device is now ready for use.

After use, the sliding body 15 is pushed down over the maximum distance 14 of the strips 11. The strips 11 are thereby compressed and release the sleeve part 3a, which is pushed down by the web 16 of the sliding body 15 until it falls into the toilet bowl.

The web 16 prevents the sleeve part 3a from becoming jammed in the tolerance range between the strips 11 and the sliding body 15.

The paper of the thin-walled sleeve part 3a softens quickly during the rinsing process and can easily pass through the curvature of the odor trap.

The water penetrating through the holes 9 in the sleeve wall prevents floating during the rinsing process, so that the cleaning part 2a can be rinsed away quickly.

The sliding body 15 is now located at the lower end of the holding and operating part 1a and is pushed upwards before or during the next opening operation.

Fig. 12 shows a further advantageous embodiment of the holding and operating part 1a, which consists in that, in contrast to the previous example, preforming of the strips 11 can be omitted, i.e. the distance between the two strips 11 remains constant. The sliding body 15 is equipped with two spring clips 18 in the manner of clothes pegs, which clamp the sleeve part 3a on the holding and operating part 1a.

The cleaning part 2a is stripped off by loosening the clamps 18 and sliding the sliding body 15 downward, as in the previous example. If it is accepted that the cleaning part 2a should be opened and wiped off by hand, the holding and operating part 1a can also be designed with an undivided shaft and a sliding body can be dispensed with. The length of the sleeve part 3a is then expediently dimensioned such that it projects beyond the pool edge with the greatest possible immersion depth 8, so that it is ensured that after use of the device it can be handled in a clean area and stripped from the holding and operating part 1a .

In this case, as shown in FIG. 13, in order to prevent unwanted detachment of the pushed-on sleeve part 3a from the holding and operating part 1a, it can be clamped thereon in the area which corresponds to the upper end of the drawn-on sleeve part 3a or friction-based holding device 19 can be provided, which can consist of rubber, foam or other known materials in a wedge shape.

Using the figures 14, 15 and 16, another possible implementation of a cleaning device according to the invention will now be explained, in which the holding and operating part 1b is designed with a round or oval cross section. Either the previously described sleeve part 3a with a flat cross section or one with a round or oval cross section 3b can be fitted onto this holding and operating part 1b shaped in this way. In the following, only the distinguishing features of a flat cleaning part 2a, as previously explained, are listed. The round or oval sleeve part 3b is preferably made from one or more layers of paper, e.g. Crepe paper, produced and can be made thin and with a small diameter.

The sleeve part 3b has in the inner area as a lateral protective zone 6 a water-impermeable layer, for example made of plastic film, and forms a watertight unit with the cleaning head 4b made of paper attached to the lower end and a lower protective zone 5. The inner diameter of the sleeve part 3b is so large that there is so much tolerance between the sleeve wall and the holding and operating part 1b that the sleeve part 3b can easily be pushed on and stripped off. For better handling, the sleeve part 3b is equipped with ring-shaped stiffening zones, which are preferably provided with water-soluble, but solid in the dry state, such as adhesives, glues, etc. or can be produced by material deformation or thickening. After use, the paper of the thin-walled sleeve part 3b quickly softens during the rinsing process, loses rigidity and can therefore easily pass through the curvature of the odor trap.

As shown in Figs. 16 to 21 can be seen, the holding and operating part 1b can be split lengthways. In this case, on its shaft 22 provided with longitudinal grooves 21 there is provided a strip 23 which is spread apart in the manner of a leaf spring and which is firmly connected at the lower end to the shaft 22 of the holding and operating part 1b and - in an unspread, i.e. pressed state with this forms an essentially circular cross section.

A longitudinally displaceable wiper ring 24 is slid over the holding and operating part 1b, the inner circular cross section of which is provided with fins 25 pointing radially inwards, which run into the grooves 21 of the shaft 22 (FIGS. 18 and 19). The grooves 21 do not extend all the way to the lower end of the holding and operating part 1b, as a result of which the scraper ring 24 is prevented from falling down. A spreading device 26 in the form of a spring, a rubber or the like, at the level of the upper end of the pushed-on sleeve part 3b, pushes the bar 23 away from the shaft 22, so that the pushed-on sleeve part 3b is held by friction. A spreading device can be omitted if the bar 23 is made, for example, of elastic plastic or metal or wood and is preformed in such a way that it does not rest on the shaft in the idle state

22 abuts, but is spread as far away from it as is necessary for a secure holding of a sleeve part 3b.

At the upper end of the holding and operating part 1b sits above the shaft 22 and bar 23 a handle 27 which, like the scraper ring 24, is provided with fins 25 which extend into the upper end of the holding and operating part 1b Grooves 21 grip. In the area of the bar 23, the handle 27 has an internal widening 28, which offers the bar 23 the necessary freedom of movement.

Based on the previous embodiment with the preformed pair of strips 11 and the sliding body 15, the function of the scraper ring 24 with fins 25 corresponds to that of the sliding body 15 with web 16 and the function of the spread strip

23 and the shaft 22 that of the pre-bent pair of strips 11. The operation is carried out analogously to the previous embodiment.

The design of the cleaning part in paper offers the following additional advantages:

The manufacturing process is simple. In a flat version it resembles that of a coffee filter bag, a paper case or a paper bag, in the round version it is similar to a cigarette tube. The manufacturing costs are low; waste paper can also be used. The cleaning part made of paper is light and can also be easily transported in large quantities due to its low weight and small dimensions. When dry, the cleaning part has the rigidity necessary for handling and still manages with a small cross-section and thin wall thickness. A stock of disposable cleaning parts can therefore be kept in a small space. In the case of the round cleaning part, it is conceivable to store it in a kind of quiver, which at the same time forms the packaging and can be set up on the floor or fastened to the wall.

The flat cleaning parts are suitable for a row-mounted suspension, which may be done through holes in the sleeve-shaped part and pins attached to the wall. In a further possibility for keeping the rear eiπaπdergereihten Reiniguπgsteile flat in the central region of the lateral edges of the length are perforated by and the outermost ^'regions of the edges by adhesive bonding or by brackets above unterein¬ other and connected to the storage container. After the holding and operating part has been introduced, the cleaning part is removed by tearing off the perforation from the storage container which is open at the front.

In another type of storage, the individual cleaning parts are combined to form a bundle by means of an adhesive strip attached to the side, which is attached as a whole to the storage housing. A cleaning part is removed by inserting the holding and operating rod and pulling the cleaning part off the adhesive strip.

When washing away, the rigidity of the cleaning part decreases rapidly under the influence of water. This makes it easy to wash away. The paper decomposes easily and therefore does not represent an additional burden on the sewage treatment plant.

The desired, at least temporary, watertightness can be achieved by impregnation with water-soluble substances per se, which likewise means that there is no additional stress or delay in the decomposition process. The process of dissolving the impregnating agent can even be indicated by a color change to indicate to the user that he now has to strip off the cleaning part or that a cleaning part had already been immersed in the water.
