Abstract

The invention relates to a rubbish container (3). The available volume of said rubbish container can subsequently be adjusted according to requirements in that an insert (1, 6) designed for this purpose divides the rubbish container as required into different chambers with different volumes. Said insert can also be used as fastening means for a partition (15) which can be subsequently introduced.

Description

"Household waste container"

The invention relates to a device for household waste containers, with which existing household waste containers that are out of date in their application can be adapted to the requirements of modern household waste collection. It is therefore not necessary to take existing household waste containers out of use and to replace them with modern, new ones.

Modern household waste collection requires the use of multi-chamber waste bins (German Patent 25 58 433) in order to collect and load different waste fractions separately in a single operation in a space and labor-saving and thus cost-saving manner. This system has now been successfully introduced internationally. However, it requires the procurement of new garbage bins, in which webs are provided on the floor, into which the partition is inserted and usually at the upper edge. is fastened with clips. This procurement is very profitable, but it requires considerable investments.

At the same time, there is a trend to reduce the usual 120 and 240 liter rubbish bins in order to force citizens to recycle by reducing the volume of the garbage bins. Many municipalities do this and also measure household garbage charges on a volume scale, sometimes coupled with the weight of the garbage.

The object of the invention is to enable a variable subdivision of a refuse container which initially does not have a special holding device for a partition (so-called mono refuse containers in contrast to multi-chamber refuse containers) with a vertical partition wall in order to create a so-called multi-compartment refuse container . It is advantageous if, in order to adapt to the individual and seasonally fluctuating volume of the various refuse fractions, the vertical partition can be variably moved in predetermined positions. At the same time it should be gfls. be possible to adjust the total usable volume of the container to new, smaller dimensions. In order to save costs, raw materials and transporters, it is important to continue using the existing garbage containers (especially those made of plastic injection molding on two wheels, as they have generally been introduced in sizes between 80 and 240 liters since 1973). At the same time, the hygiene and functional reliability of the separation should be ensured. The assembly of the device should also be possible quickly and easily.

State of the art;

DE 36 12 965 shows a garbage container divided in depth, in which the individual partial volumes are emptied via various wall flaps lying one above the other. With this container it is not possible, as in the above-mentioned DE 25 58 433, to empty the garbage separately in different fractions at the same time in a cost-saving manner. This document therefore does not affect the subject matter of the invention. This is also the case with DE 3531554. The "Biotainer" (brochure from Gebr. Otto KG, Kreuztal) shows an intermediate floor with holes about 20 cm above the bottom of a waste bin, which is supported on ribs that are attached in the lower area of the bin. It is used to ventilate organic waste, so that it rots better. The font does not meet the problem. This also applies to DE 3628305, where a foldable intermediate floor is shown. With this, neither the usable volume can be reduced, nor can a partition be attached.

The patent EP 0 428 185 has disclosed how, in a newly produced domestic waste container, partition walls can be attached in a very simple manner in this new waste bin. At the same time, trouble-free production and volume-saving shipping and simple assembly of the partition in the container are made possible. However, the patent requires the new production of a garbage can in order to attach the webs for holding a partition in the garbage can. Different sizes of containers are produced for different volumes of household waste containers.

DE 44 10 627 shows a device which is introduced into undivided household waste containers and consists of a rail which is glued to the bottom of the container or is clamped between two opposing inner walls on the bottom of the waste container. This version, which is used only for retrofitting a partition in a fixed position, also has the disadvantage that gluing requires a very thorough cleaning of the glue point, which is hardly feasible: with a new waste container, the mold release agent, with used grease and Waste residues are removed thoroughly. This is very labor intensive and difficult to do at the bottom of the container, since the waste containers are so deep and narrow that they can hardly be reached on the ground. Then these bars must also be positioned exactly. The jamming mentioned in the document is also unsuitable for practice, since it loosens in use due to the bulges and vibrations of the waste containers (the latter in particular when emptying) and migrate against the diagonal and / or vertical of the container and therefore does not hold the partition on offer lower end. Thus, a clean separation is no longer guaranteed, furthermore, the partition wall can fall out when the container is tipped out, if the upper fastening can no longer absorb the forces which occur due to this construction and in some cases run obliquely to the walls.

Another disadvantage can be seen in the fact that this solution favors the contamination on the bottom of the container and is therefore detrimental to hygiene because of the remaining germs, especially since glued webs cannot be removed for cleaning.

It is also known to screw partitions into existing ordinary waste containers - this is how the first user tests of the multi-chamber waste system were carried out. At the same time, these solutions have the disadvantage that they rigidly define the division ratio (that is, they do not allow rapid adaptation to different types of waste) and that they can only be used to divide the useful volume of an older waste container, but not to reduce it overall as desired. Such a new container volume is 80 liters, for example. However, the rubbish bins installed on two wheels in the past two decades usually have a volume of 120 and 240 liters. If smaller containers, which are cheaper in the calculation of the removal fees, are now required, new, expensive containers have to be produced and distributed, and the old ones have to be scrapped. This is undesirable from an environmental point of view. The new small containers have a higher floor, which in this position integrates with the side walls will be produced. However, it has poor standing properties, for example when exposed to wind. The floor of these new containers is raised so that, on the one hand, the dimensions of the container opening in the system correspond to the pouring devices on the vehicle, and on the other hand, to comply with the labor standards for the transport handle height and the EU directive for handling loads.

Advantages of the invention;

In the invention, there is a particular advantage that the footprint of the garbage container is not reduced, and thus, especially after emptying in strong winds, it tends to fall over much less (risk of traffic on the roads) than new, smaller containers. Because of the existing, original bottom of the container to be converted, the focus is particularly low when empty, which improves stability.

Another advantage can be seen in the fact that the inventive retrofit device can be easily and safely attached even in the inaccessible depth of the waste container, can be dismantled for cleaning and can be cheaply and energy-savingly produced on small injection molding machines in a plastic injection-molding design, and also in a ratio injection molds for the production of waste containers, cheap, quickly produced injection molds are used. The transport volumes are also

Retrofit device small and therefore cheaper than new garbage containers. Many municipalities are often unable to procure new waste containers due to the financial situation. It is also possible to turn a mono waste bin into a multi-compartment waste bin, even with a variable partition, with simple means and low costs.

Problem solving and examples of execution;

The problem is solved according to at least one of claims 1 or 14. The subclaims contain further advantageous developments of the invention.

Figure 1 shows an example of an embodiment of the solution in which a bowl-shaped or trough-shaped insert (1) with vertically oriented webs or grooves (2) is attached to the bottom (4) of the waste container (3). The webs are used in a known manner (see EP 0 428 185) for fastening a vertical partition (5) in this waste container. Figure 2 shows a simplified top view of the insert (1) of Figure 1, which is advantageously dimensioned so that it fits snugly on the inside of the waste container 3. This both prevents the insert 1 from twisting and prevents contamination under this insert, which could be caused by liquid (e.g. in the case of organic waste) which could run down the inside walls of the container. It is also possible to provide this insert with a sealing ring or elastic lip on its upper edge in order to prevent liquid from penetrating under the insert.

Fig. 2a + 2b show in plan view that the webs (2) are suitable for fastening the partition in a known manner for different divisions of the garbage container volume (right / left and / or front / rear), furthermore that the webs are not the entire dimensions of the z. B. trough-shaped insert, but, as the webs 2 'show, can be advantageous in terms of hygiene (avoidance of dirt angles) only in some areas. Figure 3 shows that it is also possible to design insert 1 not only as a lower trough, but as a kind of flat base plate (6). In this case, it is advantageous to attach the vertical partition (5) to the base plate (6) prior to the introduction thereof or to connect it in one piece.

A quick, uncomplicated assembly outside of the waste container (3) is possible here. Base plate (6) and vertical partition (5) can be easily screwed or dowelled together or fastened to one another with a plug connection. Here it is possible to dispense with webs (2) (see Fig. 6) for fastening, and yet the partition is easy to install (without turning the container over to make holes on its bottom, etc.).

Of course, such a base plate 6 can also be sealed laterally as described above or curved upwards, so that it presses even better against the inner walls of the waste container from above.

Figure 4 shows an embodiment in which the base plate (6) is designed to be very material-saving, in that it is designed on both sides of the partition 5 as a segment plate 6 ". Of course, this only makes sense if the useful volume of the container is not to be reduced at the same time. Also this fastening cannot be rotated in the waste container and is therefore secure because the plate or tub width is selected in such a way that it prevents the base plate / tub from twisting. This can also be done by the tub / plate reaching into a corner In this case, care must be taken to ensure that the dimensioning ensures that the container cannot be rotated or moved. Fig. 5 shows the example of the flat intermediate plate 6 'that this can also be suitable for reducing the height of the garbage container 3. It goes without saying that a trough-shaped insert 1 or a curved bottom can also be used, as is shown in FIG. 1 with insert 6. However, it is important to pay attention to the dimensions according to the container cross-section (due to the taper of the waste container).

In order to better identify the residual volumes resulting from the intermediate shelves and not to confuse the different sized inserts for the different heights, it makes sense to use different colors (e.g. yellow, blue, green ...) for the respective insert sizes.

The insert 1 or trough or the intermediate plate 6 'can be fastened by screwing through the walls of the waste container 3. But it is also possible to make openings in the garbage container walls and insert 1, 6 (tub / plate) with elastic

Attaching tabs (8) or lugs (8), Figure 6. These tabs can be molded on or subsequently attached to the plate / tray (insert 1, 6). In the case of the molded noses, they are advantageously designed so that they have at least the thickness of the container wall. For example, the easiest way to mount the plate / tub is to hang these tabs / noses on one side into the wall holes in the waste container and then press them down on the opposite side until the tabs or noses pass through the corresponding holes Engage with the other wall (or walls). Since any liquids should not escape through the holes, the wall openings should preferably be avoided on the side of the waste container that forms the inside when the waste container is emptied with the lifting and tilting device. These are generally those of the garbage can emptying bar (10) facing sides. Furthermore, they can be sealed with conventional means such as rubber rings, sealing compound, etc. However, this is not necessary if the tabs / lugs are slightly conical so that they have a sealing effect on the inside of the wall openings. They can also be quickly and conveniently secured against slipping out on the outside using screws, cross bolts and the like. the like. or fix by welding.

In order to be able to empty any liquid that has flowed downward despite the insert 1 or the intermediate plate being sealed, it is advantageous to provide the insert or intermediate base preferably with at least one opening against the middle of the front side of the container (the one with the emptying strip 10). to allow the liquid to leak when the container is tilted. In order to keep this breakthrough free of constipation due to thrown-in rubbish, it can be covered at the top in the form of an umbrella.

Figure 7 shows an embodiment of an intermediate plate 6 with ridges 9 which serve to reduce the usable volume of the refuse container and form a support to the bottom of the refuse container. The fastening tabs (8) are used here to prevent them from falling out. The height of the webs 9 determines the position of the intermediate plate 6 in the waste container and thus the usable volume above it. The partition 5 in turn serves to form the multi-chamber waste container in a reduced size.

It is also advantageous to design such an intermediate plate (1, 6) in such a way that one side has ribs for fastening partition walls to form a multi-chamber waste bin, while the other side is smooth. It can then be used as required. The ribs are also a reinforcement of the floor. Figure 8 shows, by way of example, that it is also possible to subdivide the container volume using different, intersecting partitions. These devices can also be designed with their individual parts that can be dismantled.

Basically, the vertical partition 5 can be fastened in its upper area in a known manner with clips, dowels, bolts or screws. In any case, it is ensured that this upper fastening is loaded as little as possible, that the transverse forces on the wall - in particular in the tilted position for emptying - are well absorbed and thus twisting or falling out of the partition wall is reliably prevented.
