Description

Waste press

The invention relates to a waste press according to the preamble of patent claim 1.

Waste compacting devices have become increasingly important recently. While there were previously large waste presses that were used, for example, at waste disposal sites, today there is an increasing need for waste presses for use on a smaller scale with increasing costs for waste and especially for the amount of waste.

Devices for pressing waste are described, for example, in CH 676 819 A5 (publication date March 15, 1991) and GB 2 078 161 A (publication date January 6, 1982). According to these publications, waste is compressed in a kind of bucket with the help of a press piston. The compressed waste can then be transferred from the bucket into a rubbish bag or the like.

These devices have the disadvantage that the waste has to be decanted after it has been compressed. In addition, the devices are relatively complex and therefore not particularly suitable for private households. But it is precisely the waste in the private household that accounts for a relatively large proportion of the cost of housing with rising waste prices.

According to the prior art, some devices for compressing or pressing waste are known which can be used in the home or in residential complexes. These devices are basic more simply constructed than the devices specified above.

For example, DE 29 12 188 AI (publication date 09/10/80) shows a simple ramming tool for refuse compaction with a head piece and a handle piece. The ramming tool is weighted on the head piece and can be used to compact rubbish in rubbish bins.

Furthermore, from DE 35 16 170 AI (publication date November 6, 1986) a hand press device is known in which a pressure plate can be moved vertically in a container with the aid of a threaded spindle. A device for comminution is arranged below the pressure plate and is actuated by means provided on the threaded spindle. By providing the device for shredding, a greater volume reduction of the waste can be achieved than with pressing devices without this device. However, the construction of the hand press device is relatively complex due to the provision of the comminution device. It also has the disadvantage that it either has to be transported as an additional device to a container with waste and has to be held or attached there during use, or that it is firmly connected to a container into which the waste is filled. In the first case, it is not ensured that the device can be sufficiently fastened, so that actuating the threaded spindle becomes complicated. In the second case it is necessary to transfer the waste from the container.

The same disadvantage exists in the device described in DE 43 33 057 AI (publication date March 30, 1995) in a mobile construction for compressing solids in containers. This relatively complicated structure has a carrier with a hole for guiding a press tube. There is one on the press tube Press plate attached. For use of the device, the carrier is fastened to a container using specially provided means.

A more simply constructed device for pressing compressible material, in particular waste or the like, is shown in DE 41 34 391 AI (published on October 17, 1991). This device consists essentially of a lower support plate and a side bracket connected to it, on which a lever linkage is mounted with a press adjuster attached to it. The press adjuster is arranged on the lever linkage such that it is provided on a support arm which is articulated on the lever linkage. It enters an opening in a container that stands on the carrier plate and presses the material in the container. According to this device, waste can be pressed at the place where it can remain after pressing. However, since there are no means for fastening a container on the carrier plate in this device, it is possible, due to the unstable mounting of the container, that it migrates on the carrier plate during pressing or, in the worst case, even tips over.

Therefore, the known device is not suitable for containers that are per se less stable, such as containers made of paper. In particular, there may also be difficulties in using the devices for empty tetra packs, such as those used for milk, juice, etc., as containers for waste. These containers are of great interest as waste containers because they are very bulky as waste and take up a lot of space in the rubbish bag. This space requirement can be reduced a little by squeezing the packs together, but the result remains unsatisfactory. The packs have also been used as containers for waste. However, without the possibility of being able to compress the waste in the inherently unstable container, this did not lead to a satisfactory result.

Based on the specified problems with inherently unstable waste containers and the last-mentioned publication, it is the object of the present invention to provide a simply constructed and easy-to-use waste press with which waste is stored in a special inherently unstable container, in particular in a so-called "Tetra pack", can be pressed.

This object is achieved by a waste press as defined in claim 1. The dependent claims show advantageous configurations of the waste press according to the invention.

The waste press ge ass of the present invention is particularly designed such that an inherently unstable container can be safely stored in it during pressing of the waste.

Thanks to the waste press for special containers, it is possible to make optimal use of the space in the rubbish bag, because much more rubbish can be brought into the individual containers when pressed. This then takes up much less space in the rubbish bag. This in turn means that much less expensive rubbish bags are required for the same amount of waste, which means that private households have the opportunity to save on waste taxes.

Embodiments of the waste press ge ass of the present invention are described in more detail below with reference to the figures, wherein Fig. 1 shows a side view of a waste press according to an embodiment of the invention; and

Fig. 2 shows a side view of a waste press according to another embodiment of the invention.

Ge ass of Figure 1, a waste press 1 consists of a container receiving part 2, on which a connecting part 7 for connection to a press medium holding part 10 for holding a press medium 15 is attached.

The container receiving part 2 has the shape of a cuboid in the size of a container to be received in the container receiving part 2, such as in particular a "tetra pack", and has a base plate 3, three side walls 4, an upper opening 5 and an open side 6 on. It is preferably made in one piece from metal, which is cut according to the final shape and then bent. On the open side 6, a very short side wall preferably extends from the bottom part 3 into the open side 6 upwards. This short side wall has projections which protrude beyond the width of the base part 3 and, starting from the sides of the short side wall, are bent at a right angle towards the adjacent side walls 4 and are attached to or welded to the latter. This construction of the container receiving part 2 ensures that it is solid in itself and that a container inserted into it via the open side wall 6 and the upper opening 5 is fixed there.

The connecting part 7 has a U-shape and is made of metal, wherein in the assembled waste press 1 the open side of the U-shape is opposite to the side wall 4 of the opposite side wall 6 of the Container receiving part 2 is directed and is attached or welded there by means of projections 8 provided on the adjacent closed sides of the U-shape. The projections 8 protrude outward from the two legs of the U-shape of the connecting part 7 at a right angle. The connecting part 7 extends on the outside of the container receiving part 2 beyond it and has no projections at its upper end 9.

The pressing means holding part 10 is attached to the upper end 9 of the connecting part 7. This pressing means holding part 10 has a U-shape, is made of metal and can be moved by a bolt 11 on the connecting part 7 with the three sides of the U-shape to form a continuation of the three sides of the U-shape of the connecting part 7 in a hinge-like manner. The movement of the pressing means holding part 10 is restricted on the one hand in the upward direction by the middle side of its own U-shape, which abuts the middle side of the U-shape of the connecting part 7, and on the other hand by the not up to the upper end 9 of the Connection part 7 formed projections against which the legs of the U-shape of the pressing medium holding part 10 abut when this is moved in the direction of the upper opening 5 of the container receiving part 2. The pressing means holding part 10 can thus be moved over a range of approximately 90 °.

The pressing means holding part 10 has in the longitudinal direction in its central section a bore 12 which is provided for receiving the pressing means 15 and as a guide for the latter. At its free end, the pressing medium holding part 10 is preferably provided with a protective device 13, which is preferably a protective cover made of plastic. In addition, it is preferably provided in the bore 12 with a support section 14 which, like the pressing means holding part 10 itself, has a U-shape. The support section 14 extends from the free end of the pressing means holding part 10 to going beyond the bore 12 and is inserted with the open side of its U-shape towards the open side of the U-shape of the press-medium holding part 10 and fastened or welded there.

A pressing rod 16 of the pressing means 15 runs through the bore 12 of the pressing means holding part 10 and is closed at its upper end by a handle 18 and at its lower end by a pressing plate 17. The pressing rod 16 can be moved back and forth in the bore 12 up to its respective ends and is guided through the bore 12. The press plate 17 is essentially in the form of a rectangle such that it can be inserted into the special container when it is lowered.

In addition, the waste press 1 according to the present invention can have a device for storing adhesive tape. This device is preferably attached to a side wall of the container receiving part 2.

FIG. 2 shows a waste press according to a further exemplary embodiment of the present invention, only the differences from the exemplary embodiment shown in FIG. 1 being discussed here.

In particular, the side walls 4 of the container receiving part 2, which adjoin the open side 6 of the container receiving part 2, are shaped in the direction of the open side 6 and in the direction of the upper opening 5 such that they have no corners but are rounded. This prevents snagging at corners when using the waste press 1, for example when inserting or removing a container. The rounded side walls 4 each preferably have a central cutout according to their outer shape. This makes the weight of the waste press 1 lighter without restricting its functionality.

A further difference between the exemplary embodiment in FIG. 2 and the exemplary embodiment shown in FIG. 1 consists in the design and arrangement of the pressing means holding part 10, the associated pressing means 15 and the pressing plate 17 attached to the pressing means 15. As shown in FIG Pressing medium holding part 10 is mounted on the connecting part 7 via the bolt 11 in such a way that the pressing medium 15 mounted on the pressing medium holding part 10 is mounted offset downwards relative to the bolt 11. This vertically offset mounting of the pressing means 15 is achieved by a curvature of the pressing means holding part 10 at least in the area up to the point at which the pressing means 15 is mounted on the pressing means holding part 10. This structure ensures that the press plate cannot interfere with the release of the container receiving part 2 for inserting or removing a waste container.

In the present exemplary embodiment, the pressing means 15 is stored on the pressing means holding part 10 via a hinge connection in the pressing means holding part 10, which is preferably a bolt 19, via which the pressing means 15 is rotatably mounted on the pressing means holding part 10. The pressing means 15 itself has two pressing means side walls 20 which run almost parallel to the open side 6 of the container receiving part 2 and to the two side walls 4 adjoining the open side 6 of the container receiving part 2, each of which is preferably in the form of a triangle are, the surface of which widens starting from the bolt 19 in the pressing means holding part 10 until it reaches a pressing plate 21 and merges into it. The press plate 21 is thus arranged between the press medium side walls 20 and preferably formed with these in one piece. It is similar to the press plate 17 of the exemplary embodiment shown in FIG. 1, but is provided with a guide aid for insertion into the waste container through the press agent side walls 20. A further guide aid is preferably provided by an extension of the press plate 21 which is bent upwards in the direction of the pressing means holding part 10 on the side facing away from the open side 6 of the container receiving part 2.

Compared to the exemplary embodiment shown in FIG. 1, the exemplary embodiment in FIG. 2 is distinguished in particular by the fact that the pressing is carried out by a built-in lever mechanism, so that less effort is required to press the waste.

After the description of the waste press according to the present invention with reference to the figures, there now follows a brief description of its operation.

A special container, preferably a “tetra pack” provided with an opening at the top, is inserted into the container-receiving part 1 via the upper opening 5 and the open side wall 6. Since the dimension of the container receiving part 1 is precisely adapted to the container and due to the design of the container receiving part 1 with the side walls 4 and with the short side wall on the open side 6, the inserted container is adequately fixed. When the container is inserted, the pressing means 15 is completely pulled out of the pressing means holding part 10, which means that the pressing plate 17 rests on the pressing means holding part 10. Furthermore, the pressing means holding part 10 is preferably in the open state possible by the hinge connection to the connecting part 7. This means that the pressing means holding part 10 and the connecting part 7 approximately in their respective longitudinal direction are aligned with each other on a line or at an angle of approximately 180 °.

After the container has been inserted, the pressing means holding part 10 is moved via the hinge joint in the direction of the upper opening of the container receiving part 1. It is best if an operator of the waste press moves the pressing medium holding part 10 through the handle 18 attached to the pressing rod 16. However, it is also possible for the operator to move the pressing medium holding part 10 by using the protective device 13. However, this has the disadvantage that before or upon reaching the final state of the pressing means holding part 10, i.e. of the state in which the pressing means holding part 10 forms approximately a right angle with the connecting part 2, the pressing rod 16 of the pressing means 15 runs automatically through the bore 12 in order to move the pressing plate 17 in the downward direction or in the direction of the waste. This can be avoided by using the handle 18. Then, by holding the handle 18, the movement of the pressing means holding part 10 and also the movement of the pressing rod 16 and the pressing plate 17 can be carried out in a controlled manner.

If the state of the right angle between the pressing means holding part 10 and the connecting part 2 is reached, an operator can guide the pressing plate 17 through the opening in the container in the direction of the waste via the handle 18 and the pressing rod 16 and there by moving the up and down Press plate 17 to press the waste. If additional waste is to be placed in the container, the previously described process for clearing the opening on the container can be carried out in reverse order. When the container is completely filled and the waste is compressed or compressed, the container is then removed from the container receiving part 1 and can be replaced by a next container. The waste press shown in FIG. 2 is even easier to operate. In this waste press, it is actuated exclusively via the protective device 13 as an operating handle and then via the lever mechanism provided by the bolts 11 and 19.

The above description makes it clear that the waste press is simple, holds a container securely in place and is extremely easy to use. Thus, the waste press according to the present invention can advantageously be used in private households. In particular, a reduction in the volume of waste can be achieved by the waste press according to the present invention, which leads to a not inconsiderable reduction in the cost of waste.
