DETAILED DESCRIPTION OF THE INVENTION

(10) The subsurface refuse system for side loading collection as described by the current invention is equipped with a cover (2) supporting the paving which has two or more hinges and opens up to 90 degrees, by means of one or more electric or electro-hydraulic cylinders (3) combined with other gas cylinders.

(11) The gas cylinders and the electric or electro-hydraulic cylinders (3) attached to an underground bunker (4) and to the cover (2) have a driving action system electrically feed to allow the automated opening of the lid up to 90 degrees and also the automated closing. The cylinders (3) electric or electro-hydraulic cylinders may be powered by a solar system comprising one or more photovoltaic panels and the movements of the cover (2) are remotely controlled using a single device by means of continuous control buttons.

(12) On the surface connected with the cover (2) there is an input bin (1) located at a height of around 90 cm to allow the waste deposition.

(13) Inside the underground bunker (4) is located a container (6) for collection of the refuse and one internal platform (5). The internal platform (5) is fixed to the bunker (4) and swings from the initial position connected with the walls of the bunker and to the walls of the container (6) to a horizontal position. The refuse container (6) is collected with a side loading lifter (16) installed in the collection truck (17).

(14) FIGS. 1 and 2 shown the subsurface system, comprising a deposit input bin (1), a cover (2) which opens up to 90 degrees, a container (6) for collection of refuse, an underground bunker (4) and an internal platform (5) fixed on the underground bunker (4). The internal platform (5) is positioned between the walls of the bunker (4) and the walls of the container (6).

(15) The container (6) has a mechanism (7) installed on two opposite sides where each one consists of: One movable arm (8) with a pin (9) for automatic connection with the side loading lifter (16) and a roller (10) installed at the top of the referred movable arm (8); A fixed arm (11) with another pin (12) for another automatic connection with the side loading lifter (16).

(16) FIGS. 1 and 3 show the container (6) with the container's lateral movable arms (8) opened.

(17) In each mechanism (7) of the container (6) is installed a spring (13) in the interior of the said fixed arm (11) responsible for the mechanism movement: when the container (6) is inside the bunker (4), due to the weight of the cover (2) that is closed, the movable arm (8) is inside the fixed arm (11) and the spring (13) is compressed; when the cover (2) is opening, the roller (10) of the movable arm (8) moves on one channel (18) installed in the cover (2), the spring (13) is extended and the movable arm (8) translates vertically out of the bunker.

(18) In FIG. 4 is represented the spring (13) installed inside of the fixed arm (11) and the movable arm (8) translating inside the fixed arm (11).

(19) In FIG. 5 is represented the connection between the roller (10) installed in the movable arms (8) of the container (6) and the channel (18) installed in the cover (2).

(20) When the two movable arms (8) of the container (6) are positioned outside of the bunker (4), the side loading lifter (16) of the collection truck (17) connects to the pins (9) of the two movable arms (8) in order to lift the container (6).

(21) FIG. 6 shows the container (6) being lifted inside the bunker (4) by the automatic side loading lifter (16) of the collection truck (17). The lifter (16) of the truck (17) is connected to the pins (9) installed in the movable arms (8).

(22) During the lifting of the container (6), two movable elements (14) of the internal platform (5), positioned between the walls of the bunker (4) and the walls of the container (6), swing into horizontal position due to the force of a gas shock absorber (15) attached to the bunker (4) and to each of the two movable elements (14). When the two movable elements (14) are in a horizontal position, each one approach in two electromechanical locks (19) attached to the opposite sides of the bunker (4). After the internal platform (5) approach, the side loading lifter (16) disconnects from the pins (9) of the two movable arms (8) in order to release the container (6) into the said internal platform (5) that supports it temporarily.

(23) In FIG. 8 it is possible to see one electromechanical lock (19) fixed in the bunker in order to support one side of one movable element (14) of the internal platform (5) in the horizontal position.

(24) When the container (6) is temporarily supported in the internal platform (5), the side loading lifter (16) of the collection truck (17) connects to the pins (12) of the two fixed arms (11) of the container (6) in order to enable the lifting and the turning of the container (6) to be emptied to the collection truck (17).

(25) After emptying, the side loading lifter (16) moves the container (6) to the same position where it was temporarily supported in the internal platform (5) and disconnects from the pins (12) of the two fixed arms (11).

(26) The four electromechanical locks (19) that close the two movable elements (14) and support temporarily the container (6) in the horizontal position are opened by an electric contact in order to permit the gravity vertical movement of the container (6) and the consequent swing of the movable elements (14) of the internal platform (5) against the wall of the bunker (4). The opening of the electromechanical locks (19) is controlled remotely.

(27) In FIG. 7 it is possible to verify the container (6) being loaded by the automatic side loading lifter (16) of the collection truck (17). The lifter (16) of the truck (17) is connected to the pins (12) installed in the fixed arms (11) in order to unload the refuse into the vehicle. With the container inside the bunker, the operator controls remotely the electric or electro-hydraulic cylinders to close the cover (2) and consequently the roller (10) of the movable arm (8) moves back on the same channel (18) of the cover (2), the spring (13) is compressed and the movable arm (8) translates vertically in to the inside part of the bunker (4).

(28) As is evident to experts in the field several changes are possible without going beyond the scope of the following claims.
