is retracted, and is caught by claw-like elements on laterally protruding stub axles or handles (see DT-AS 1 226 036). There are also similar devices for emptying wheeled large garbage containers are known in which the support and tilting arms of the tilting frame reaching over the side of the container under an upper, flange-like container edge to grab.

On the other hand, emptying devices for garbage cans are also known in which the tilting frame has hooks into the Bracket-like parts of the garbage cans are to be hung. Finally, emptying devices for garbage cans are also known, a frame element for receiving the lower rim of the rubbish bin and the holder gripping the upper rim of the rubbish bin exhibit.

In contrast, rubbish bins in the form of garbage cans with 110 liters and 220 liters capacity have recently become known, which have two wheels on the lower band area of their rear wall. Usually these containers stand on their bottom Edge. But if you tilt them backwards, they can be driven like a cart with the wheels .. There the wall this well-known container is thin, and mostly made of If there is plastic, no special elements need to be attached to which the previous emptying

Container wheel is capable of receiving the bag. the Container wheels can be retracted quickly and safely into such a pocket, and are also used in every tilted position of the The tilting frame is held securely in the bag without being at the pocket inlet any locks or interlocks would be required.

The swivel range of the sewing bags compared to the respective The support and tilt arm can be limited in such a way that the receiving pocket with its front part practically only extends upwards their starting position after the support and tilting arm can be pivoted back and forth. This avoids that the receiving pockets At the beginning of the tilting movement, first perform a downward pivoting movement and then again in the upper part must swing back the tilting movement. Rather, it is the tilting movement of the receiving pockets on the safe Locking the container wheels required area limited. For this limitation, a with Carrying and tilting frames, or a counter-stop that works together on this limit stop. This limit stop and / or the counter stop can be adjustable.

Another, additional security measure, in particular takes effect at the beginning of the upward tilting movement and at the end of the downward tilting movement, can be provided to this effect that the side wall of the receiving pocket lying on the floor inr area of the pocket entrance a has to be overrun by the respective wheel, strip-shaped upwardly projecting backstop. Furthermore, the receiving pocket on the side wall which is at the top in the starting position of the tilting frame and preferably also on the outer one Front wall with a lead-in slope for the respective wheel be trained. In this way, the entry of the wheels into the receiving pocket is made much easier.

In the context of the invention, it is also possible that the to emptying container between receiving support and tilting arms in their mutual distance on the axial To make the RadX distance of the various containers adjustable. This makes it possible to empty containers of different widths with one and the same device. This can include, for example a pivot lever provided with handlebars can be provided, which is larger in one end position and in the other end position sets a smaller mutual distance between the support and tilting arms.

The support and tilting arms 3 are designed to extend laterally over the lower part of the garbage can 1, and each carry a sewing machine 6 for a container wheel 2 at the free end End of the respective support and tilting arm 3 pivotally mounted, these tilting axes 7 of both receiving pockets 6 should fall as possible in a straight line.

In the upper area a rotatable roller-like abutment 8 is arranged between the two support and tilting arms 3 , against which the upper part of the container wall 9 of the refuse receptacle 1 opposite the wheels 2 rests when it is inserted into the tilting frame.

The two Aufnähmetaschen 6 are to be partially encompassed of the wheels 2 formed. For this purpose, they have a closed outer end wall 11 (see FIGS. 4 to 6) and a

The peripheral edge of this end wall 11 partially surrounding wall strips 12. As a result, a flat side wall 12a, which sits on the floor, is formed on each receiving pocket 6, starting therefrom an essentially semicircularly curved pocket base 12b and a pocket cover 12c. The rear side of the receiving pocket 6 in the starting position is open. As can be seen from FIGS. 1 to 3, 5, 6, the pivot axis 7 is displaced backwards with respect to the center of curvature of the pocket base 12b, namely by an amount which corresponds approximately to the radius of curvature of the pocket base 12b. This means that the distance between the pocket pivot axis 7 and the pocket bottom 12b is always greater than the radius of the largest container wheel 2 that the pocket 6 can accommodate, and the distance corresponds approximately to the diameter of the largest container wheel 2 that the pocket 6 can accommodate. As FIGS. 5 and 6 show, a bearing bracket 13 is attached to the outer side of the pocket end wall 11, which rotatably supports a journal 14 fastened in the end of the respective support and tilting arm 3, but secures it against axial removal.

In the examples shown, in the area of the open rear side, each receiving pocket 6 has an insertion bevel 15

formed on the pocket front wall 11 and a lead-in bevel 16 on the pocket top 12c. On the down on the floor laying, essentially flat pocket side wall 12a is one of the respective in the area of the open rear side of the bag Wheel 2 to be overrun, strip-shaped upwardly projecting backstop 17 is formed.

In addition, the receiving pocket 6 can also be one of the end wall 11 opposite, inwardly directed, along the wall strip 12 extending flange 18 carried between the respective wheel 2 and the garbage can 1 engages. This is of particular importance when the support and tilting arms 3 can be adjusted laterally Importance to prevent that when the garbage can 1 is inserted, the support and tilting arms 3 moves outwards and the Wheels 2 could be released from the receiving pockets 6.

At the receiving pockets 6, the pivoting movement is limiting Attacks 19 attached. In Figure 1 to 3, such a stop 19 is marked in a possible attachment position thick reproduced. In this way of attachment, the receiving pocket 6 has moved from the starting position shown in FIG from the possibility of an angle towards the respective To pivot support and tilting frame 3 down until the limit stop 19 hits against the respective support and tilting arm.

But a delivery position at 19 'is also shown weaker, in which the limit stop 19 'is already in contact with the respective support and tilting arm 3 in the starting position. The first option has the advantage that the Aufnähmetasche 6 immediately when pivoting the carrying and Tilting arms 3 assumes an inclined position upwards, and offers increased security against the wheels 2 turning back. It but it must be accepted that when pivoting downwards the receiving pocket 6 does not essentially interfere with it flat side wall 12a, but with the lower, rear region of the pocket bottom 12b hits the bottom, and until reaching the starting position according to Figure 1 has to slide slightly over the floor. The arrangement of the Limitation stop 19 'given the second possibility, the first downward pivoting movement of the receiving pockets 6 is omitted, so that the inclination of the flat side wall 12a to the pocket bottom 12b pivot corresponding to the upward the support and tilting arms 3 increases. For this purpose, the receiving pocket opens with its flat side wall 12a when it is pivoted downwards laid the ground.

As FIG. 3 shows, an end limit stop 20 can also be attached to the end wall of the receiving pockets against the support and tilt arm 3 when the tilt frame in

the upper end of its tilted position runs. Like Figure 3 can be seen, this can be done before the actual upper tilt end position is reached. This additional end stop 20 prevents the receiving pockets 6 with the garbage can 1 suspended in them from being in the upper tilted position the tilting frame could perform a rocking motion.

As shown in Figure 4, the tilting frame for mutual lateral adjustment of the support and tilting arms 3 and the attached to them be formed Aufnähmetaschen 6. As a result, is made possible, in one and the same device with appropriate conversion, both the above-mentioned wider, as well as narrow ones: to empty rubbish bins. The carrying and For this purpose, the upper end of the tilting arms 3 is seated axially displaceably on the pivot shaft 4 by means of eyes 21. The pivot shaft 4 can be designed as a spline or toothed shaft for torque transmission to the support and tilting arms 3. It is enough, however, In the example shown, a transmission plate 22 firmly attached to the pivot shaft 4 also for torque transmission, the one at the bottom between the two support and tilting arms 3 extending transmission rod arrangement 23 carries "

This transmission rod arrangement is than to the lower End of the transmission plate 22 attached guide and transmission sockets 24 with axially displaceable guided in it actual rods 25 formed. In the area of these rods, control arms 26 engage the two support and tilting arms 3. At the inner end these handlebars 26 are attached to a crank lever 27, which is itself pivotably mounted on the bushing 24 and has an actuating arm 28.

The abutment 8 is formed in this example by a shortened abutment roller 29, in which each support and tilting arm 3 ago an axle journal 30 engages coaxially and axially displaceably.

Figure 4 shows the device in the setting for wider refuse containers 1. To switch to narrower refuse containers is only to pivot the hand lever 28 to the right in the illustration in FIG 3 contracted into the mutual position corresponding to the narrower garbage can.

The operation of the device according to the invention is as follows:

After the tilting frame has been set to the side of the garbage can 1 to be emptied with the hand lever 28, the garbage can 1 becomes cart-like, i.e. with the wheels 2 opposite wall 9 (see FIG. 1) forward between two the support and tilting arms 3 and retracted with the wheels 2 in the receiving pockets 6 until the wheels over the strip-shaped Backstop 17 have run away. The garbage can is then tilted backwards from the cart-like position in the normal, vertical position in which it then, as shown in FIG. 1, with the wall 3 opposite the wheels 2 against the stop shaft or stop roller 8 lies. In this starting position, the tilting device acting on the pivot shaft 4 is then actuated. The carrying and Tilt arms 3 then swivel upwards. If the limit stop 19 of the receiving pockets 6 is in the arrangement 19, the recording pocket 6 leads during the first part of the Upward pivoting movement of the tilting frame from a counter-pivoting movement, and thereby slides with the side wall 12a and the Pocket bottom 12b over the ground until the limit stop 19 hits the support and tilting arm 3. From that moment on (when arranging the limit stop 19 'from the beginning) lead the recording pockets 6 together with the support and tilting arms 3 an upward pivoting movement, that of that of a

So

Excavator bucket is comparable. This common movement continues up to about the middle tilt position shown in dashed lines in Figure 2 (when the limit stop 19 'is arranged into a slightly higher tilt position). From there on, the limit stop 19 or 19 'rises again from the support and tilting arm 3 to pivot upwards relative to the support and tilting arm 3. This relative pivoting movement of the receiving pockets 6 takes place until the end limit stops 20 hit the support and tilt arm 3, and then again a common pivoting movement of support and tilt arm 3 and receiving pocket Force 6. As a result, rocking movements of the with the receiving pockets 6 on the support and tilting arms 3 are suspended Rubbish bins 1 prevented, and the essential for emptying the trash and loosening the contents of the container When η hits the tilting frame, it hits its end stop Transferred to the garbage can 1 at the tilting end position.

When the tilting frame is swiveled back, the steps described above take place Backward motion sequences. The garbage can 1 is safely set down on the floor again. When arranging the limit stop 19 becomes a sliding movement of the arched pocket during the last part of the downward pivoting movement
