The invention relates to a garbage truck and an associated garbage can with means for emptying of the garbage can in the garbage truck.

Garbage trucks and assigned garbage cans can be found at widespread use for the collection of household waste. The full garbage can is thereby through the means touched, lifted, tipped and emptied in the approaching garbage truck for emptying. Fast, Economic and reliable garbage disposal requires a number of demands on such Facilities, of which the essentials are: quick, convenient and reliable recording of the garbage can through the emptying means, secure locking of the garbage can after it Detection in such a way that the vessel cannot loosen or emerge from the emptying means during lifting and tilting, As far as possible avoidance of dry friction between those who work together during lifting and tipping Parts, simple, strong design of these parts, so that they are flawless even in robust operation and exact cooperation of the parts is ensured.

In known garbage trucks and associated garbage bins, the trolley is provided with two lifting arms, one end of which is hinged to the car and the other end with a lever with a trunnion is equipped, while the garbage can on two opposite sides with support members such is provided that the support pins engage the support members for lifting and tilting the vessel can. The lock that prevents the waste container from escaping from the support members during tilting is to prevent, is effected by using bent sheet metal parts that interlock.

Such known devices have considerable disadvantages, that of fulfilling the aforementioned Oppose the demand. The sheet metal parts do not only slide during the turning (tilting) of the Garbage can pass each other under dry friction, but the sheet metal parts are also - what at the rough operation of the device is of particular disadvantage - sensitive to deformation; beautiful if these sheet metal pieces are deformed slightly, however, the individual parts cannot work together well take place more. The garbage truck as well as the garbage can are used roughly, and the filled garbage can generally has a considerable weight; will now be used to prepare the If the lifting process is not carefully "targeted" with the lifting arms, the ends of the arms will be against butt the bent pieces of sheet metal, creating local garbage trucks and associated garbage can

Deformations occur and perfect assembly

ao men work or correct locking is no longer guaranteed. But there is also an aggravating factor that if the locking point intervenes incorrectly or incorrectly, a wrong support point is created, around which the sheet metal parts roll, causing the garbage can to fall while tilting can occur.

The invention is based on the object of garbage truck and associated garbage can with means for Emptying the garbage can in the garbage truck so that the disadvantages of known devices be avoided, perfect locking despite simple and powerful training of the cooperating Parts and an inevitable self-adjustment of the correct support point without deformation individual parts can be reached even with the roughest treatment.

The solution to this problem is according to the invention that the support members as support webs in Form of two substantially U- or L-shaped fishing forks are formed, of which the first one Limitation of the relative mobility of the garbage can with respect to the lifting arms in a horizontal position Direction and the second in cooperation with the first forms a limit in the vertical direction, while the trunnions are located near the ends of the levers.

This inventive design of the garbage truck and the associated garbage can is achieves that the trunnions easily engage "searching" in the support members, while the position of the Catching forks to each other ensures that the garbage can is locked in the lifting arms at all times.

It is particularly advantageous to design the forks of the garbage can in a double T-shape, with the The web of the T lies in the center plane of symmetry of the vessel, the upper flange of the T is wide at the ends is bent down and the lower flange of the T has edges that are slightly bent upwards.

In a further advantageous further development of the garbage truck according to the invention and the associated one Garbage can, in which the support pin lever provided at the end of the lifting arms by means of a The operating rod is rotated to empty the garbage can, the operating rod is with a End on a fixed tab arranged on the garbage truck and with the other end on an extension of the lever outside the connecting line of the trunnions near the fixed pivot point of the lever on the lifting arm connected in such a way that the garbage can during the upward movement of the Hebeanne is automatically tilted.

Further details of the invention are explained in more detail below with reference to the drawing. In this shows

F i g. 1 shows a side view of the most important parts of the device according to the invention and

F i g. 2 on an enlarged scale in side view of the garbage can according to FIG. 1 with part of the Lifting arms.

In Fig. 1 the rear part of a garbage truck 1 according to the invention is associated with one Garbage can 2 according to the invention shown.

The rear part of the carriage 1 consists of a loading device 3 of conventional construction in which a pouring opening 4 is provided halfway up the rear side. The loading device has furthermore a lifting device 5 consisting of two arms 6, one end of the arms are hinged to the carriage 1 by means of eyelets 7. The other ends of the arms 6 are each provided with a lever 8 provided, which has a support pin 9 at both ends. The lifting arms 6 continue with a projection 10 located in the vicinity of the hinge point 11 is provided. This projection 10 is with the end of the piston rod 12 of a lifting unit 13, 14 connected.

The garbage can 2 has two opposite side walls as a double-T-shaped support webs 15 formed as flat strips which form, as it were, catching forks 16. The bridge 17 each Support web is provided in the center plane of symmetry 18 of the vessel so that the points of attack for the pin 9 of the lever 8 are slightly outside of this center plane of symmetry. The upper part 19 of the Support web 15 is roof-shaped, the lower part 20 is channel-shaped and has a small, upward bent edge.

Each lever 8 is via a connecting rod 21 with one on the lower side of the loading device 3 provided and located in the same plane as the lever 8 stop 22 connected.

The device according to the invention works as follows: The garbage can 2 is on the roadside drove. Once the garbage truck has arrived, the lifting arm 6 is lifted by means of the lifting unit 13, 14 brought into their lowered position shown in FIG. Then the garbage truck drives backwards towards the vessel, or the vessel 2 is brought to the trolley and pressed against the lifting arms, wherein the upper pin 9 strikes against the web 17 of the support web 15. This is followed by means of of the lifting unit 13, 14, the lifting arms 6 raised. The support pins 9 of both lifting arms 6 engage in those formed by the roof-shaped part 19 Catch forks 16 a. After this state has been reached, pressure medium continues to be supplied to the cylinder 14, so that the lifting arms 6 move further upwards with simultaneous entrainment of the vessel 2. The arrangement of the support webs 15 and the length of the

ίο web 17 in terms of the distance between the The pin 9 is such that the weight is taken up by the upper roof-shaped part 19.

During the lifting, the levers 8 are now gradually tilted by means of the connecting rods 21. Here, the vessel 2 is supported on the levers 8 via the webs 17 of both support webs 15, with FIG at a certain moment the weight of the vessel is taken over by the lower channel-shaped part 20 will.

ao After emptying the vessel in the loading device 3 the lifting arms 6 are lowered again, whereby the whole process is reversed Direction takes place and the container 2 finally comes back to the ground, after which the garbage truck can continue to the next vessel.

The arrangement of the strip-shaped support webs on the outer sides of the garbage can is therefore special advantageous because it gives a very strong shock-resistant construction. However, it is also possible, not the fishing forks, but the pegs 9 on the sides of the garbage can and the To provide forks at the ends of the lever 8. The construction according to the invention enables Finally, the lifting and emptying of a garbage can on the floor at an angle.
