Description:
ASSEMBLY FOR COLLECTING REFUSE For the collection of refuse such as domestic refuse or small commercial waste, use is usually made of containers in which the refuse is temporarily stored.

This refuse is collected by a refuse collecting service by means of refuse collection trucks. An advantage of the use of such containers is that a certain quantity of refuse can be stored temporarily, and be presented to the refuse collection service in practical manner. The refuse collection trucks are adapted to the use of the containers in that lifting devices can pick up the containers and the refuse can hereby be tipped into the refuse collection truck without manpower.

Recently the need has arisen to separate diverse types of refuse at source, whereby different refuse flows can be processed separately.

Known for this purpose is a container with a separating wall whereby two compartments are created in the container, whereby refuse can be processed in two fractions. Further known are insert units with two fixed bins for the possibility of separate processing of four fractions of refuse.

The present invention provides an assembly, comprising : - a container comprising a base and one or more walls extending from the base to an upper edge, - a frame which is placeable on the upper edge of the container, and - at least one holder placeable in the frame.

Such an assembly allows the holders to be adapted to the desired uses of companies, households and/or refuse collecting services.

The holders can further be cleaned in practical manner. A loose holder cdDfor instance be filled

separately at a different location from the container or the frame and then easily transferred to the location of the container.

In a preferred embodiment, the frame comprises first engaging means for engaging grippers for emptying the holder. For the separate processing of refuse fractions it is recommended that the content of the holders and the content of the rest of the container can be emptied successively. Using this embodiment, the frame with the holders is lifted out of or from the container, whereby the holders can be emptied separately of the container. A further advantage of the engaging means is that the frame can be picked up by means of lifting means of the refuse truck, whereby emptying can be performed mechanically. Despite the possibly small volume of the holders, exhaustive use of manpower is unnecessary.

The frame preferably comprises positioning means for engaging the edge of the container and/or the upper edge of the container comprises complementary positioning means for engagement of the positioning means thereon. Such positioning means have for instance the advantage that placing of the frame on the container can be carried out in simple manner. An approximate positioning of the frame is for instance sufficient in this embodiment for an exact positioning. Such positioning means are further useful for holding the frame in place, whereby the frame is present in a stable manner on the container.

In a further preferred embodiment, the container comprises at least one separating wall. The combination of such a separating wall with a frame creates a refuse container with four compartments for four different refuse fractions.

The holders are preferably attached releasably in the frame by means of attaching means such as snap elements, screw elements or sliding means for attaching the holder to the frame. It is however also possible to envisage permanent fixing of the different holders to the frame, for instance via welding or glueing of holders to the frame.

In a further preferred embodiment, the holder comprises openings for ventilation or weight reduction.

Further advantages, features and details of the present invention will be elucidated on the basis of the description of an embodiment with reference to the annexed figures: - fig. 1 shows a combination of diverse embodiments in exploded perspective view.

A container 1 comprises a base and four side walls 11, 12,13, 14. An upper edge 5 is situated on the top side of the side walls. A frame 2 can be placed on this upper edge 5.

Two (collecting) bins 3,4 can be arranged in frame 2.

At the rear the container has handles and hinge means 17 for handling the container and for hinged mounting of lid 6.

The container is further provided with separating wall 15 for dividing the waste compartment from front to rear into two waste compartments. It hereby becomes possible in known manner to separate waste into two fractions.

Frame 2 is provided with two locations for arranging collecting bins 3,4. The frame is formed by base plate 20 on which the edge 15 is arranged as well as strengthening parts 16 and 19. Extending on the underside of base plate 20 is a wall 22 which is further

attached to base plate 20 by means of strengthening ribs 21.

Base plate 20 together with front wall 22 and strengthening ribs 21 serve as engaging means for lifting means of a refuse truck for the purpose of emptying bins 3,4.

Bins 3,4 can be attached in frame 2 by sliding in the bins by means of edges 18 and grooves 35. The figure shows an embodiment wherein the bins are pushed into the frame from the rear. This is also possible for instance from the side (s), the front, the underside or the top.

Alternative methods of attaching the bins in the frame are by means of a snap mechanism or a screw mechanism.

An advantage of the present embodiment is that bins 3,4 of different size can be arranged in frame 2 in accordance with the requirement of the users. Standard frames can hereby be applied while simultaneously applying a variety of bins.

Bin 4 comprises four side walls and an upper edge 25 in which is arranged groove 35. In similar manner bin 3 comprises four side walls 31,32, 33,34 and an upper edge 36 in which is arranged groove 38. Bin 3 is further provided with openings which decrease the weight of the bin. The openings are also suitable for ventilating the content of the bin. An organic waste fraction for instance can hereby be kept relatively dry, optionally with the use of a paper bag. For the purpose of keeping organic fractions dry in such a container, it is further possible to give the container a ventilated form, for instance by leaving open a channel between edge 5 and lid 6.

In a particular embodiment the volume of the container is for instance 370 litres, it can be loaded with 150 kg, it has a wheel of 300 mm, a width of 745

mm, a depth of 860 mm, a total height of 1070 mm, a container height of 960 mm, and is manufactured from a green plastic which can be applied at ambient temperatures of-40 C to +80 C. The frame is in this case modified to fit round the edge of the container.

The bins are hereby placed on the inside of the container during placing of the frame. The lid of the container is closable over the assembly of container and frame. The assembly or the individual parts are preferably manufactured from one or more plastics suitable for refuse containers.

The invention is not limited to the above described embodiments; many modifications can be made by the skilled person on the basis of the description. The rights are defined by the appended claims.
