ABSTRACT:
BODY OF THE INVENTION
This invention relates to the technological field of systems which are used in the city to collect recyclable or non-recyclable garbage, for the purpose of removing it and afterwards sending it to recycling or disposal centers.
More particularly, the invention relates to the sector which manufactures and uses systems in which garbage which has been deposited through the appropriate openings accumulates in one or more containers which are located underneath these openings, awaiting removal to be sent their final destination.
Usually, in order to occupy less space, these containers are underground receptacles with a high capacity, but they may have limited usable space inasmuch as the garbage which piles up in the approximate shape of a pyramid reaches up to and blocks the aforementioned openings, preventing all the usable space from being filled.
Removal of this garbage therefore becomes difficult and complex, and consequently expensive.
Another reason why containers with higher capacity and usable space cannot be utilized is the fermentation and reproduction of bacteria which generate malodorous gas and vapors with high content of germs which adversely affect public health.
Consequently, for example in the large cities, these containers are undersized with respect to the requirements of the inhabitants, and must necessarily be emptied frequently, more often than once a day in some cases.
SUMMARY OF THE INVENTION
The inventor of this invention thought that it would be possible to avoid all the drawbacks cited above by devising systems with containers having a larger usable space in that it would not be limited by the aforementioned factors, because the garbage could be moved in a transverse direction with regard to the openings, thereby causing the garbage to occupy areas of a container which are relatively far from the area lying immediately below the corresponding openings, while keeping the non-recyclable garbage—defined as solid urban waste—at a temperature low enough to prevent the aforementioned fermentation and reproduction of germs and bacteria.
To do this, the object of this invention is to devise a system for collecting recyclable or non-recyclable garbage, as described in the preamble of the attached claim
1
, with features which are described in the characterizing part of that same claim.
A more detailed description of a preferred embodiment of a system as claimed in the invention follows. This example shall not in any way be considered binding or restrictive of the scope of the invention, which includes all possible embodiments conceivable to one skilled in the art.
