401GM20 Collection container for recyclable materials

The invention relates to a collection container for recyclable materials, which comprises a body with at least one emptying flap, which is kept closed or released via traction means by at least one horizontally displaceable actuating element arranged on the top of the body. Such a collection container is described and shown in the German utility model application G 94 16 727.3.

For emptying such containers, there are special lifting devices on collection vehicles that hydraulically move at least one actuating element horizontally relative to an abutment. Instead of an abutment, a second actuating element can also be provided.

In the container mentioned at the beginning, at least one actuating element is designed as a two-armed lever. This enables a desired force-displacement ratio to be determined by selecting the lever arm lengths accordingly. The displacement stroke of the actuating element is relatively small in relation to the opening stroke of the emptying flap,

while the available force of the hydraulic cylinder is more than over-dimensioned for its movement.

However, to achieve the desired path transmission ratio, the lever arms that extend into the container become quite long and bulky. If translatory slides are used instead of the lever (or levers), the path transmission/force reduction must be achieved in another way.

For this purpose, the invention proposes that the traction means between the actuating element and the emptying flaps be designed to reduce the force and thus increase the distance. A pulley arrangement is preferably provided.

An embodiment of the subject matter of the invention is shown in the accompanying drawings and is explained in more detail below.

Fig. 1 shows a schematic sectional side view of the area of the container deck wall in which the actuating element is arranged, Fig. 2 is a section along line 2-2 of Fig. 1.

Under the cover wall 10 of a container body, two U-profiles 14 are welded on both sides of a slot 12, with their legs facing each other. Support rollers 16 of a slide or carriage 18 run in the rails thus formed, consisting of two side cheeks 20, an upper cross bolt 22 and an axle 24 in a welded construction. A cable pulley 26 is mounted on the axle 24.

An abutment 28 also has a cross bolt 30. The abutment is welded to the cover wall 10 or to the U-profiles 14. A steel cable or rope 32 wraps around the rope pulley 26 and is attached at one end near the abutment. The other rope end runs over a second rope pulley 34, which is rotatably mounted on an axle 36 under the abutment.

The carriage 18 is shown in its final position, in which the rope 32 opens the discharge flap (not shown) at the bottom of the container

closed. If the container is to be emptied, a hydraulic working cylinder attached to a hoist is anchored to the two cross bolts 22, 30 and holds the slide 18 away from the abutment 28 so that the flap remains closed as long as the container is lifted and swung over a vehicle loading bay. The working cylinder is then actuated and releases the slide 18. The emptying flap can now open under the weight of the collected goods, with the cable 32 pulling the slide 18 towards the abutment.

A spring that biases the slide 18 into its closed position can be provided, but is not shown. Likewise, rubber tabs that cover the slot 12 and are carried along by the slide 18 are not shown.

Claims (6)

401GM20 Protection claims: 1. Collection container for recyclable materials, comprising a body with at least one emptying flap, which is kept closed or released via traction means of at least one horizontally displaceable actuating member arranged on the top of the body, which traction means are designed to transmit displacement/reduce force. 2. Collection container according to claim 1, in which the at least one actuating element is a lever. 3. Collection container according to claim 1, wherein the at least one actuating member is a slide. 4. Collection container according to one of claims 1 to 3, in which two actuating members are provided which can be displaced horizontally towards or away from each other. 5. Collection container according to one of the preceding claims, in which the traction means comprises a pulley block. 6. Collection container according to claim 6, in which the pulley is designed for a 1:2 path ratio and a 2:1 power reduction.
