The patent 929 776 refers to a garbage can emptying, in which a torsion bar spring arranged in the pivot axis of the front panel, which between Side walls of the bed arranged and with the garbage can by hand or by mechanical means Tipping device swiveled back into the bed so far that i> ie then by the own weight in the starting position falls behind.

When using a mechanical tilting device, e.g. B. one acted upon with pressure medium Rubbish bin dumper had to pull the piston in the rubbish bin dumper's cylinder while it was tipping back pressurized medium on its opposite side in order to keep the moving parts of the rubbish bin tipper, namely piston, piston rod, toothed segment, swivel arm shaft and swivel arm, in their Starting position.

This mode of operation required a complicated construction of the tipper cylinder of the control element and the Hydraulic lines.

The object of the invention is to design the device so that the torsion bar does not only the front panel and the garbage can swiveled back out of the emptying, but also at the same time the swivel arm of the rubbish bin tipper and the tipper parts coupled to the swivel arm, such as Swivel arm shaft, toothed segment, piston rod and piston, after the pressure medium has expanded the unilaterally loaded rubbish bin tipper returns to its starting position.

The invention enables a simple construction of the tipper cylinder, the control member and the pressure medium supply lines, since now the piston of the rubbish bin tipper only acts on one side with pressure medium needs to be because the tipper only has to manage the tipping. Since also the previously required sliding claws on the swivel arm are no longer required, which is a two-part training of the swivel arm made necessary, the swivel arm can now be made in one piece and be designed tapered towards its free end. In addition to the easier training of the parts that are cheaper to manufacture, material and weight are also saved.

In the drawing, the device according to the invention is shown schematically. It shows

Fig. 1 the garbage can emptying in view with the on and off switchable torsion bar spring in section,

Fig. 2 the rubbish bin emptying with the rubbish bin tipper., Seen from the side, in section.

The rubbish bin tipper 1 is connected to the pivot arm shaft 3 on which a release arm 2 for the control unit of the dump truck and a one-piece dump for garbage cans

so the free end tapered swivel arm 4 are wedged. In the bed 5, a front plate 6 is arranged, which at one end rotatable with its eye 7 on the bearing pin 9 and with its other end on the bearing bush 10 is stored. The torsion bar spring 12 engages with its ends in corresponding recesses in the faceplate eye 7 and in the bearing bush 10. A lock 11 that can be switched on and off engages in the switched on Position in the bearing bush 10 and holds it in place so that it is not in the Can rotate the discharge side wall.

The front plate 6 has an opening which is provided with a pivotable closure plate 13, on which a drawstring 14 engages, which opens the closure flap 13 when the front panel 6 is tilted, so that the garbage from the swiveled garbage can 17 slides into the garbage truck (Fig. 2). One between the Front plate 6 and the retaining bolt 15 arranged bellows 16 prevents the escape of Dust from the pile.

When the rubbish bin tipper 1 is actuated, the swivel arm shaft 3 with the swivel arm 4 and the rubbish bin 17 is set in a pivoting movement, whereby the upper edge of the rubbish bin rests against the front panel 6 and the front panel is pivoted through the angles α + ß into the bed . The torsion bar spring 12 is held with one end in the seat in the bearing bush 10, while the other end is rotated by the front plate eye 7, so that the torsion bar spring 12 is tensioned. Towards the end of the pivoting movement, the release arm 2 adjusts the control element of the tipper, whereby the flow of pressure medium to the tipper cylinder is interrupted.

After the garbage can, as described above, has been emptied and the tipping cylinder has been vented of the pressure medium, the tensioned torsion bar spring 12 pivots the front plate 6, the garbage can 17 and the pivot arm 4 back by the angle β . When pivoting further through the angle α, the effect of the torsion bar spring 12 is supported by the weight of the front panel of the garbage can and the pivot arm. The moving parts of the tipper follow this backward movement and are thus returned to their starting position without using any pressure medium.

The purpose of the lock 11 is to switch the torsion bar spring 12 on and off. When switched off Torsion bar spring 12, the front panel 6 can be pivoted by hand into the bed without the The torsion bar spring tensions, since the bearing bush 10 rotates in the side wall of the bed. As the front panel if it remains in the swiveled-in embankment, bulky garbage that cannot be put in a garbage can is to be loaded into the garbage truck by hand.

After such a load, the front panel is also manually removed from the bed and into its starting position brought back. The lock is then switched on again, so that normal operation

for tipping λ * οη garbage cans can be picked up again.

Claims (1)

PATENT CLAIM: Garbage can emptying with swiveling front plate and a torsion bar spring as a return spring in the swivel axis of the front panel, designed as a hollow shaft, according to patent 929 776, characterized in that that the torsion bar spring (12) except for the front plate (6) and the garbage can (17) at the same time also the swivel arm (4) of the rubbish bin tipper (1) and those coupled to the swivel arm Tipper parts, such as the swivel arm shaft, tooth segment, piston rod and piston, from the tilted Position swiveled back into its starting position after the expansion of the pressure medium from the rubbish bin tipper loaded on one side, wherein the swivel arm (4) of the rubbish bin tipper (1) is made in one piece and tapers towards its free end.
