The present invention relates to an apparatus according to the preamble of claim 1.

Such a device, described in U.S. Pat. No. 3,446,377, comprises a basket or container having a substantially sealed bottom and in which full waste containers can be placed and / or emptied by hand. The basket or container is formed of two parts which pivot relative to each other about a substantially vertical axis to form an opening through which the waste container can be inserted into the basket so that it does not have to be lifted over the wall of the basket. The body is pivotally connected via a horizontal pivot shaft to a lifting arm 15, one end of which is connected to a refuse collection vehicle, and by means of a second horizontal pivot axis parallel to the first, the lifting arm and the waste container can be raised and emptied and emptied. A major disadvantage of this known device is that the driver cannot load or fill the body without leaving the vehicle.

The main object of the invention is to provide a simple and easy-to-use collection device of the type in question, which is intended for the collection of waste bags placed on the ground, and which can be controlled by the driver without leaving the vehicle. This object is achieved in that the device according to the invention is made as defined in the characterizing part of claim 1.

Other features and advantages of the device according to the invention will become apparent from the following detailed description and the accompanying drawings, which schematically and by way of non-limiting example show a preferred embodiment of the invention, Figure 1 is a very schematic plan view of a garbage truck part and a sack collection device where it has the shape of a basket or a cage without a roof.

Figure 5 is a partial plan view on a larger scale and showing parts of the body and its support member.

10 In the drawings, reference numeral 1 denotes a waste container, of which only the rear is shown, and 2 emptying hoppers, both of which form part of a vehicle not otherwise shown. The lifting arm, which is indicated in its entirety by reference numeral 3, is pivotally mounted at one end on a support support 8 (Fig. 4) in a vehicle (not shown) around the pivot axis 4. The turning of the arm 3 is effected by means of a hydraulic lever 25. In the position shown in Figures 1 and 2 ("collecting position"), the lifting arm rests on the support 5. The lifting arm 3 is telescopic 20 and comprises a main part 6 and an extension part 7 which can be pushed out of the main part 6 and retracted inside the main part. At the outer end furthest from the pivot shaft 4, a lifting arm 3 is connected to a support arm 9f which extends along one side wall of the discharge hood approximately parallel to the pivot shaft 4.

The support arm 9 pivots about its longitudinal axis by means of a hydraulic lever, most clearly shown in Fig. 4, comprising a pivoting piston cylinder 20 and an associated piston rod 21, as well as pivot arms or articulations (not shown).

At the free end furthest from the lifting arm 3 there is a fastener 10 on the support arm 9, most clearly shown in Figures 1, 2 and 5, for a basket or collecting device according to the invention, indicated in its entirety 35 by reference numeral 11. This basket or cage comprises two halves 12 each has a base 13 and a side wall 14. In addition to both wall parts 14, the side wall of the car 11 comprises a third wall part 15 rigidly connected to the car |

5 74444 to the fastener 10. The basket is constructed of tubes or rods connected to each other as a lattice structure by welding or the like. As best seen in Figure 1, the body in its closed position is oval in the top view 5 with respect to both the bottom and the upper edge line of the side walls. Both body base portions 13 have facing edge lines ΐβ which, in the closed position of the body, both extend to the base. . Both halves of the bottom extend downwards towards these two edge lines 10 from the respective side walls 14 »as most clearly shown in Fig. 3. As can also be seen, said edge lines define blades which penetrate under the bottom of the sacks when the basket halves 12 are turned from the position shown in Fig. 2. , which sacks are gripped by the basket and which are collected in the basket 11, in the closed position of the basket, said blades of the bottom halves form a gap or crack 24 between them, which prevents the waste sacks from cutting when the basket is closed.

As most clearly shown in Figure 1, the sidewalls 14,15 of the car are substantially vertical, except in the region of the closest portions of the wall portion 15 and the wall portions 14, where the sidewalls converge slightly as they descend. This means that the longest diameter of the upper edge forming the oval shown above and closed according to Fig. 1 25 is longer than the longest diameter of the bottom oval, which in the main view coincides with the part of the former diameter.

Each body half 12 is supported by its own angle arm 30, both of which are pivotally supported by a fastener 10 and operated by means of a hydraulic lever 13 through two lever arms 25, 26 shown in Figure 5 only or similar and connecting joints 27 to open and close the body. 35 from the position of Figure 1 to the position shown in Figure 2, and vice versa. In order to allow individual movements of the basket halves 12 relative to each other, these are supported on the corner arms 17 4 74444 by means of springs 23 (Fig. 4).

The telescopic outer part 7 of the lifting arm 3 is pushed out and retracted, the body halves 12 are opened and closed by means of a lever lever device 18, the lifting arm 3 is raised by means of lever 5 and the body 11 is preferably hydraulically by means of a vehicle hydraulic system. valves operated from the driving position or any other suitable part of the vehicle.

10 When collecting (closed) garbage bags that are required to be placed "upright'1 along a road or street edge, the garbage truck or collection vehicle drives along the street and stops at each collection operation with the basket 11 (in the position shown in Figure 1) next to and in the middle Using the hydraulic valves in question, the driver first opens the basket 11 to the position shown in Fig. 2 and pushes out the telescopic arm 7 so that the basket halves 12 surround the pile of garbage bags 12. The body halves are then reclosed so that the pile of garbage bags 2 by turning the lifting arm 3, possibly after the telescopic arm 7 has been pulled more or less into the telescopic arm 6. Finally, the waste bags in the basket 11 are emptied into the emptying hopper so that the basket 11 is turned more or less up and down by turning the support arm 9. then the basket is returned to its initial position by performing the above operations in reverse order.

The embodiment 50 described above and shown in the drawings is, of course, to be considered only as a non-limiting example and may be varied in detail in many different ways within the scope of the following claims. Thus, in particular, the basket 11 can be opened and closed by moving its halves linearly away from each other and towards each other instead of twisting or turning them. In addition, the invention can also be applied to objects and vehicles other than garbage bags and garbage trucks, respectively.
