The invention relates to a device for emptying refuse collection containers or the like in refuse collection vehicles.

There are already devices for emptying garbage containers or the like in garbage trucks known, the two pivot arms mounted on the vehicle for receiving the with at least one side Have hinged door equipped garbage bin.

The invention improves such devices in order to close the side doors of the refuse collection containers close and keep it closed until the emptying process is complete. It is true Provisions for locking the closed doors have been known, however these are common left unlocked so that the doors can swing outward from the end panels.

If there are fork arms in such devices with sleeves at the ends of the The collecting container engage, so these fork arms can not easily be used to to close the doors because the doors are in a perpendicular spaced relationship with the location of the sleeves. So the doors are over the receiving sleeves. It is therefore for the driver in the vehicle cabin of the garbage collection truck only possible to keep the receiving fork aligned with the sleeves and the vehicle forward into the To drive the receiving position so that the forks are brought through the sleeves into the position to pick up the container.

If the doors are unlocked when this work is carried out, they will go into the Open position swing when the container from its supported position on the ground into its unloading position is pivoted. But this has the undesirable consequence that the waste or the garbage not only falls into the upper part of the garbage truck, but also out of the side of the doorway. More seriously, the doors can also be torn off if the sump falls into the funnel of the trolley to dispense the contents therein.

In order to avoid these disadvantages, the device mentioned at the beginning is on the swivel arms with devices provided that not only close the side doors when the collecting container is picked up, but also keep them closed until the end of the emptying process.

The door locking device is expediently made of metal sheets that are firmly connected to the swivel arms and have outward bends.

The additional device according to the invention thus ensures that the doors close automatically and to keep them closed, regardless of whether they are locked during the unloading process or not. In one embodiment, the device forms, so to speak, a door lock console that is on each of the forks is mounted so that the door is closed immediately upon engagement of the fork with a receiving sleeve and remains closed during the engagement of the fork with the sleeve.

The invention is illustrated as it is applied to a refuse collection vehicle of a conventional type is, but only as an example, the type of vehicle in which this charger is used can. Up to now it has been customary to use a vehicle chassis of the type generally indicated by the designation 1 and which is under the control of an operator on road bikes, such as the front and rear wheels, self-propelled, at the front end through which the garbage enters the Container can be done. The execution of this collecting container can of course also be of a different type be.

According to FIGS. 1 to 6, the structure of the trolley includes a pair of pivot arms 8 which are mutually are about as far away as it corresponds to the width of the car 4. These arms 8 are preferred

B. garbage, waste 15 17 on both end walls, the rotatable at 18 on the and the like, and may be designed to be attached to a body of the container and a compacting device is provided to have the garbage locking device 19 to compress the doors, when keeping it in the container closed. These doors 17 can be used for is poured. Such a container is preferred to be opened and should be opened during the other filling use that a filling opening or a funnel is locked and closed, jeter, denoted by 7, but often left open in the upper part near the. In the event that the

Doors are open when the pick-up vehicle moves into the pick-up position for the container is the Provision according to the invention is taken to close the 25 doors and keep them closed while tilting to keep.

In the exemplary embodiment, this is achieved by a door strike plate 20 on each door 17, which protrudes at an angle to its surface,

Gooseneck-shaped or have the shape of a 30 which is tapered, as can be seen in FIG. inverted U so that it is over the roof and in front. The outward slope must be in the direction of the downwards and behind the cabin 4 on the front part of the hinge edge of the door. The door of the Motor vehicle run essentially as in striking plate 20 is so on the door that it is from a 1 and 4-6 is shown. The arms must be held on the door lock bracket 21 on the broom leave the cabin completely free, but the 35 adjacent pivot arm 11 is to rest, such as.
