Device for lifting, tilting and discharging of garbage containers into the garbage truck, fitted with removable slide, one or more lever arms and hook-up by means of an oscillating and transverse mobile triangular head

Claim 1

Device for lifting, tilting and discharging of garbage containers into a collecting garbage truck,, characterized by the fact that this system invLves the following combination: - a slider (3) located between the driver's cab (1) and the truck body (2) into which the garbage is dumped, transversally sliding on guides by means of a double acting hydraulic fluid piston (4) so as to come out on one side and to retract whithin the space taken up by the garbage truck, - an upright (5) consisting of a double section fastened onto the mobile head of the slider (3), - a lever arm (7) located between the two sections of the upright (5) and hinged onto an articulated joint (6) with lengthwise horizontal axis mounted at the free end of this upright (5), this arm (7) being oscillating between its lower rest position, the container hook-on position and its upper discharging position, by means of a hydraulic fluid double acting piston (8), - a longitudinal horizontal sectional arm (10), located at the level of the truck body (2) which receives the garbage and secured, by means of an articulated joint (9) with lengthwise horizontal axis at the free and of the lever arm (7), this sectional arm (10) being able to oscillate so that it can hook on and lift the container (20), by means of a double acting hydraulic fluid piston (11), - a plate (12), one end of which will be sliding, to facilitate coupling, in the above mentioned sectional arm (10) with the aid of a double acting hydraulic fluid piston (13), while the other end of the plate (12) will be provided with an articulated joint (14) having a lengthwise horizontal axis, bearing the coupling head (15), - a coupling head (15) having the shape of a hollow triangular prism mounted on the articulated joint (14) at the free end of the plate (12) and freely oscillating between two positions (15 t , 15"), delimited by pawls (16, 17), so as to facilitate hooking up of the container and dumping of the garbage into the truck; this head (15) being provided with two opposed pin teeth (18) with tapered tip, lodged in lengthwise horizontal slots and pxperly actuated by a system (19) to secure and release the head in the female part fixed onto the container (20), - a female part (21, 22, 23) of the coupling device, fastened onto the external frontal surface of the container (20) the internal configuration of which will match the external configuration of the coupling head (15), while opposite holes (24) on the converging lateral surfaces (22) of this female part will be able to lodge the above mentioned pin teeth (18) of the head which shall thus enter these holes; so that it will be possible to hook up, lift and discharge the containers in the garbage truck, at a limited cost of installation, limited space requirements and with the help of only one operator who will also act as truck driver.
