Abstract

The invention relates to a refuse container (1) for degradable waste, the interior of which comprises two vertically arranged volumes (5, 16), whereby it is intended that the liquid received with the degradable waste should collect in the lower volume (16), from where it can also be removed. On the one hand, this volume should be large enough to be definitely able to accommodate the liquid received, on the other hand emptying of the liquid section and of the refuse container itself should be easy and trouble-free, without backmixing of the waste with the liquid occurring. To this end, the lower volume (16) is separated from the rest of the container casing by means of a forked grid (14), which is normally horizontal, but which is pivoted about a horizontal axis in the container casing during emptying. Reliable separation of solid and liquid waste and complete emptying of waste from the refuse container are achieved in this way. <IMAGE>

A WASTE-COLLECTING CONTAINER FIELD OF THE INVENTION The invention relates to a waste-collecting container for compostabie waste, in particular for collecting of household garbage or the like, essentialy oooeo consisting of an upper lid and a lower container housing S" composed of an upstanding wall part and a bottom wall and closeable by means of the lid, and including a space in the region of the bottom wall separated from the o ""interior of the container housing, which space is designed to receive the liquid contained in the waste.

BACKGROUND OF THE INVENTION Such a waste-collecting container has already been described by the inventor in an earlier published DE-OS 3939511 on December 20, 1990. This earlier publication .:teaches a number of technical features that assures that the compostable waste stored in the container housing is most of all well relieved from the liquid it contains in order to guarantee a rotting supported more by aerobic bacteria. It is among others provided for this purpose that the liquid is collected in the region of the bottom wall of the container housing and that care is taken that it can at least partly flow directly out of the container housing and/or can evaporate through a ventilating element provided on the back wall of the 2 container housing. In order to achieve this, a troughlike insert is provided which partitions off a (very small) part of the container housing volume for liquid removal. The bottom of the trough-like insert is ribbed in order to achieve, on the one hand, a stable formn with respect to the stored waste and to gain, on the other hand, indeed a space for the separated liquid which reaches the space through recesses at the bottom of the insert.

Such a structural arrangement is fully functional; however, it also has disadvantages. Thus, the space available for collecting the liquid is relatively small and is no longer sufficient in particular when liquid removal from the container housing is disturbed, for example, when the discharge channel in the area of the bottom part thereof, is clogged, especially with waste that is particularly loaded with liquid. To empty such S"a waste-collecting container can also cause difficuleeo S"ties. Thus, it is conceivable that the trough-like insert separates from the region of the bottom wall during a tipping of tne waste-collecting container.

*There also exists the risk that even when the insert remains stationary in the waste-collecting container, residues of waste under or within the insert are not dumped out.

Thus, the purpose of the invention is to provide a waste-collecting container of the type identified in detail above which can also receive large amounts of liquid and to simultaneously assure that the mechanical task of emptying of this waste-collecting container takes place smoothly and completely.

The purpose is attained according to t ention by the space being separated fr remaining interior portion of the conta- ousing by a fork-like grate which lie orizontal plane in the normal position 9-4 -i -4 -4 'a 0/<'1 SUMMARY OF THE INVENTION According to one aspecc of this invention there is provided a waste-collecting container for compostable waste, in particular for collecting household garbage or the like, including an upper lid and a lower container housing composed of an upstanding wall part and a bottom wall and closeable by means of the lid, including means defining a separated space in the region of the bottom wall from an interior portion of the container housing, which space is designed to receive the liquid contained in the waste, the improvement wherein the space is separated from the remaining interior portion of the container housing by a fork-like grate which lies horizontally in the normal position thereof, wherein the fork-like grate is pivotally supported for movement in direction of the lid about a horizontal axle provided on a back wall of the container housing, extends parallel with respect to the back wall and is supported on stationary support members on the container housing.

:'.020 According to another aspect of this invention there is provided a waste-collecting container for compostsble waste, including open top container housing and an upper oo ~lid therefor, said open top container housing having means *fee defining an upstanding wall and a bottom wall connected to 000•o said upstanding wall, grate means separating a bottom space in the region of said bottom wall from an upper interior space inside of said container housing, said bottom space being adapted to receive any liquid that may be contained in the waste, said grate means comprising a fork-like grate which includes a plurality of spaced and generally parallel tines all connected together only adjacent their respective common ends, and pivot means for 00 0 pivotally securing said grate means to said upstanding wall at a location adjacent said common end f said 35 plural tines and for movement between a first position wherein said tines are generally parallel to said bottom 0 0 wall for separating said bottom space from said upper 0 of interior space and a second position wherein said tines becomes oriented generally parallel to said upstanding 2awall, said free ends of said tines, when said grate means is in said second position, being closer to said open top of said container housing than when said grate means is in said first position thereof so that when said waste-collecting container is upended for purposes of dumping collected compostable waste, said grate means will pivot to said second position to enable said compostable waste to slide freely off said tines, past said free ends thereof.

It is preferred that the waste-collecting container includes a ventilating element, for example arranged on the back wall.

000 0: 0 00** S 0 3897b X ?ffi, 3897b 2b- 3 adjacent a back wall of the container housL^S d extending parallel roc the back nd resting on stationary supports o container housing. The arrangemen ereby such that the grate is pivotal thn a 4pprox -14- A substantially larger space for collecting the liquid is in this manner created in the region of the bottom wall of the waste-collecting container than has been possible up to now. With this it is first assured that the waste stored in the collecting container can be well drained. When the waste-collecting container is emptied, the grate pivots under the influence of gravity toward the back wall of the container housing so that even waste parts which slipped through the grate into the separated space can now be poured out of the container housing. The grate returns then into its :normal position when the waste-collecting container is set up straight again, The pivotal grate can actually be supported in any desired manner; however, if the support occurs on the ventilating element insertable into the container housing, then the grate forms a structural unit with the ventilating element, which unit only need be inserted into the waste-collecting container. It is also possible, depending on the type of waste to be stored, to keep different types of grates on hand or to equip :different waste-collecting containers with different grates. The expense is definitely warranted because a good precomposting of the waste can c.o.ur in this manner.

BRIEF DESCRIPTION OF THE DRAWINGS The details and further advantages of the invention will be discussed in greater detail hereinafter in cornection with the drawings and one exemplary embodiment, in which: V. Q VJS

4 Figure 1 is a longitudinal cross-sectional view of a waste-collecting container of the invention, and Figure 2 is a cross-sectional view taken along the line A-A of Figure 1.

DETAILED DESCRIPTION Figure 1 shows first of all a container housing 1 and a lid 2, which are the main parts of the wastecollecting container. The lid 2 is connected by a hinge 3 to the container housing 1 and has a number of openings 4 used to ventilate the interior 5 of the container housing. A ventilating element 6 is releasably fastened to the back wall 7 of the container housing 1; it has projections 8 which are each equipped with air slots 9 to ventilate the waste stored in the interior 5 of the container housing. Openings assuring a ventilating to the surroundings are provided coo in the back wall 7. As shown in the inventor's earlier publication mentioned above, the lower end of the ventilating element is open to the space 16. In this particular embodiment, the ventilating element 6 has S: plural openings 9A at the lower end of a frontwardly facing wall 6A thereof facilitating access by the space 16 to the openings 10 in the back wall 7 of the container housing i. It is to be recognized that the 0 •oventilating element in the earlier publication could, if desired, be substituted for the one shown in Figure 1.

This makes it possible to sufficiently and adequately ventilate the waste-collecting container independent of the amount of stored waste.

In the region of the bottom wall 11, near the back wall 7 of which the common transport rollers 12 are also easily rotatably supported, there are provided, adjacent a front wall, support members 13 on which the free ends of the grate rods or tines 15 of a grate 14 is supported when the waste-collecting container is in an upright position. The grate 14 is then approximately horizontally arranged. Figure 2 shows a top view of the grate.

5 The grate has in the special arrangement of the exemplary embodiment the general configuration of a coke fork with its outer periphery, in the top view, conforming approximately to the contour of the interior walls of the interior 5 of the container housing 1. The grate 14 is composed of individual, back wall to front wall extending, parallel grate rods or tines 15. The grate 14 separates the space 16 between the grate and the bottom wall 11 from the interior portion 5. The space 16 is the collecting receptacle for the liquid contained in the waste.

The grate 14 is pivotal about an axle generally designated at 17 adjacent the back wall 7 of the container housing 1. The axle 17 is formed by two stub axles 18 stationarily provided on the grate 14, extend horizontally and are otherwise approximately parallel to the back wall 7. The stub axles 18 are received in eoo bearing holes 19 advantageously provided on the side oo S"walls of the ventilating element 6. The stub axles 18 are actually the bent ends of two wire rod-like legs the spacing of which is slightly greater than the width o• ""of the ventilating element 6. A direction arrow 21 makes it clear that the grate 14 is pivoted about the axles 18 in direction of the ventilating element 6 ""during an emptying of the waste-collecting container and thereby frees the entire bottom area of the container housing 1 so that same can also be emptied.

The invention is not to be limited to the described exemplary embodiment; in particular the shape and the construction of the grate 14 and the cross sections of its grate rods or tines 15 can be chosen relatively freely. It must, however, be assured that the grate 14 can carry out the identified pivoting during an emptying of the waste-collecting container under the influence of gravity.
