Description

Quick System Device Field of the invention

The present invention relates to a quick system device for a semiunderground waste container.

Furthermore, the present invention relates to a semi-underground waste container comprising a quick system device and a quick system kit for retrofitting a semi-underground waste container.

Background

Present day consumption habits produce large amounts of waste, whereas at the same time, space, especially tightly populated areas, is running low. Therefore, semi-underground waste containers are increasing their share among waste containers. A semi-underground waste container is based on a vertical structure in which generally over 50 % of the container is located underground. The containers occupy a minimal surface area that allows practical waste collection solutions even in small and confined spaces. Semiunderground waste containers enable use of larger containers. Furthermore, gravity compacts the waste by its own weight inside the containers. Therefore, semi-underground waste containers enable less frequent waste collection. The large waste capacity reduces emptying traffic in the area and minimizes environmental load. Increasing intervals between emptyings reduce fuel costs and emissions.

Description of Example Embodiments

Semi-underground waste containers or underground waste containers comprise at least a container body, a lid and a reusable lifting bag. Semi-underground waste containers are emptied through the bottom of the lifting bag, using a hydraulic arm and a lifting chain that lifts the bag from the container body. Nowadays, for lifting there are typically strapping bands arranged in the upper part of the lifting bag. Before attaching the lifting chain to strapping bands the lid of the container has to be temporarily transferred aside and the strapping bands have to be found in order to attach them to the lifting chain. When the lifting chain is attached to the bands the bag is lifted and positioned over the collection vehicle. The trigger mechanism is released to open the bottom of the bag and waste falls into the truck. After emptying, the bottom of the bag will be closed and the bag will be lifted back into the container. However, instead of strapping bands there could be a quick system with a lifting loop on top of the lid. The metal lifting loop is fixed to the top of the frame structure that is a part of the quick system. A lid is non-openable and fixed on top of the frame structure and the metal lifting loop extends through an opening of the lid. The frame structure is fixed to the upper part of the lifting bag. The lifting chain will be attached to the metal lifting loop for lifting. When the lifting chain is attached to the lifting loop the whole quick system including the bag, the loop, the lid and the frame structure, is lifted for emptying, and returned back inside the container as explained above.

Semi-underground waste containers comprising strapping bands for emptying purposes may, however, take unnecessary time when emptied, because the lid has to be removed and also because the strapping bands have to be located for emptying. In addition, regular lid transfers may damage the lid. However, this structure is preferable, when large sized waste has to be fed into the waste container and the waste drop-hole opening with or without a lid is too small, because the lid can be temporarily moved aside. Whereas, semi-underground waste containers comprising a quick system with a lifting loop, a non-openable lid and frame structure may be faster to empty, because there is no need to move the lid aside for emptying and because the metal lifting loop is easily accessible. However, this structure does not allow large sized waste to be fed into the waste container, because the lid cannot be temporarily moved aside or opened and the waste feeding slot and/or drop-hole opening with a lid may be too small for large sized waste.

In the following, several embodiments of the invention will be described in the context a quick system device of a semi-underground waste container and a semi-underground waste container comprising a quick system device. It is to be noted, however, that the invention is not limited to shown embodiments only.

In embodiments of the invention, a quick system device for a semiunderground waste container comprises a frame structure, a lifting bag and a lid. The frame structure is, for example, a metal frame structure arranged to be fixed to the upper part of the lifting bag. When the lifting bag is inside the waste container and more particularly inside the container body, the frame structure supports the lifting bag to its place. The frame structure may comprise, for example, protrusions or other suitable structure, which support the lifting bag inside the container body. When the bag is inside the container body, protrusions are on the edges of the container body. For example, if the container body is a rectangle, when seen from above, the frame structure may comprise at least one protrusion for each side of the container body, or if the container body is a circle, when seen from above, the frame structure may comprise protrusion, for example, for 4 to 8 points in the circle. The quick system device further comprises a lifting loop and a hinge structure. The lifting loop and/or the hinge structure may, however, be a part of the frame structure. The lifting loop extending through an opening of the lid, when the lid is closed, is arranged to be used for lifting the bag from the container for emptying. The hinge structure is attached between the lid and the frame structure so that the whole lid is openable i.e. tiltable to a predetermined opening angle. Thus, the whole lid is openable in addition to a drop-hole lid of a drop-hole opening of the lid. The opening angle may preferably be, for example 20 to 60°, for example, 45°, 50° or 55°. Preferably the angle is so big that large sized waste, for example, bigger refuse sacks, for example a 60 litres sack, can be fed to the container, but so small that the lid would preferably not open up to the vertical position in order to avoid the wind from catching the lid. When the lifting bag is lifted for emptying by means of the lifting loop of the quick system device, the lid, the frame structure and the hinge structure are also lifted.

The lifting bag may be any type of structure inside a semi-underground waste container that is arranged to be lifted from the container for emptying and arranged to be opened from the bottom when emptied. The lifting bag may be made of, for example, woven polypropylene, plastic, durable plastic, aluminum and stainless steel or combination of them.

The frame structure may be formed to be suitable for any shape or size of a semi-underground waste container body. When seen from above, the shape of a semi-underground waste container body may be circular, rectangular, oval, pentagon, hexagon etc. The lid may also be formed to be suitable for the shape and size of container body of the semi-underground waste container.

Some of the users may want to use an additional temporary liner inside the lifting bag, for example, a sake of hygiene. The idea of the temporary liner is to change the liner in connection with emptying. Previously the liner was placed to the lifting bag so that the upper part of the liner was bent over the upper edges of the container body like a regular trash bag in a trash can of a house. In the case of a container with a lifting bag with strapping bands and removable lid, there was no connecting place for the liner inside the container, therefore the liner was bent over the edges of the container body. Whereas, in the case of a container with prior art quick system with an integrated lid, it was not possible to attach the liner to the quick system device, because the lid was integrated, non-openable, and a drop-hole opening of the lid is too small and/or inconvenient to be used for placing the liner to the lifting bag and attaching it to the frame structure of the quick system. Therefore the liner is also in this type of containers bent over the edges of the container body. However, the quick system device according to embodiments of the present invention enables fixing of the additional liner to the quick system device through the space between the openable lid and the frame structure. The frame structure may, for example, comprise fixing devices for the liner. Fixing devices may be, for example, hooks, clamps, fixing pins or any other device suitable for fixing the liner to the quick system device so that it locates inside the lifting bag of the semi-underground waste container.

Figure 1 shows a simplified structure of a prior art quick system 10. The quick system 10 comprises a frame structure 11, a lid 16 (shown by broken line) and a lifting bag 12 (only part of the bag is shown). The lifting bag 12 is arranged to be fixed to the frame structure 11. The frame structure 11 is arranged to be located on the edges of a container body 13 (only upper part of the container body is shown) of a semi-underground waste container and the bag inside the container, when the quick system 10 is in the use position. The frame structure 11 comprises protrusions 14 supporting the quick system 10 on the edges of the container body 13. Further, a lid (not shown) is arranged above the quick system 10 and the container body 13.
