Bauer, Heinz-Dieter, Eichendorffstr. 3, '4286 Südlohn "Tipping beam for stack tipper"

The innovation relates to a tilting traverse according to the generic term of the main claim.

Tilting traverses of the generic type are known, in which a connection between the latch and the area of the forklift driver's seat makes it possible to release the latch from the forklift seat in the simplest way, so that it is guaranteed that the forklift driver can no longer get into the swivel area of the actual container. A pull rope is provided in the simplest way. In practice it has been found that the latch can come loose on difficult ground over which the forklift is driving, which is of course undesirable.

The innovation is based on the task of improving the generic known device in such a way that, while retaining the advantages of the known device, it is now ensured that an unintentional release of the latch is not possible, i.e. that the latch can only be released by operation from the driver's seat.

This problem underlying the innovation is solved by the teaching of the main claim.

Further advantageous embodiments are explained in the subclaims.

In other words, it is proposed that a toggle lever rod is connected to the end of the latch facing away from the latch head, which is in a "dead center position" in the transport position, so that an unintentional release of the latch is not possible. This toggle lever rod can be moved by the forklift driver beyond the dead center position, either via a traction device or hydraulically or pneumatically, and then the latch can be released. It is clear that an unintentional release of the latch can no longer occur due to simple vibrations in the ground.

An example of the innovation is explained below using the drawing.

The drawing shows a tilting beam 1, which consists of a steel frame with entry pockets 2 for the forks of the forklift truck. At the front free end of the tilting beam 1 there are hook arms 3 pointing downwards, in whose hooks 4 the corresponding bolts of the container can be stored.

Inside the hook arms 3 or just one hook arm 3, a latch 5 is pivotally mounted around a pivot bearing 6 and in the locking position comes against a stop, while a rotary movement downwards around the bearing 6 is freely possible. The latch head 8 is arranged at the end of a latch lever 9. At the end of the latch lever 9 facing away from the latch head 8, a toggle lever rod 10 is connected, which consists of a toggle lever 11 and a toggle lever 12. The toggle lever 11 is here

hinged to the ratchet lever 9 and hinged to the knee lever 1?, which in turn is hinged to the tilting cross member at the other end, as is illustrated by the hinge pin 18. The hinged connection between the knee lever 11 and the knee lever 12 is shown as knee joint 14 in the drawing.

A spring 16 is connected to the end of the knee lever 12 facing away from the knee joint 14, which tends to pull the knee lever 12 into the position shown in the drawing in such a way that the actual knee lever rod 10 moves beyond the extended position into a so-called "dead center position" in which the actual latch 5 is securely locked against unintentional release.

At the lower end of the toggle lever 12 there is a pulling means 17, with which the toggle lever rod 10 can be pulled beyond the dead center position shown, so that the latch head 8 can then fall downwards, thereby unlocking the latch.

Instead of the traction device 16 shown in the drawing, a hydraulic or pneumatic device can of course also be provided. By pulling on the traction device 17, the latch 5 is moved downwards and thus releases the stop so that the tilting movement of the container (not shown in the drawing) can now take place.

Protection claims: 1. Tilting beam (1) for stacking tippers with hook arms (3) carried by the tilting beam (1) and at least one latch (5) for locking positioning of the stack tipper in the FIi 11 position, wherein the latch (5) is pivotably supported about a horizontal axis (6) by the hook arm (3), characterized in that at the end of the latch head (8) facing away from the A toggle lever rod (10) is connected to the ratchet lever (9), the toggle lever (11) of which is connected at one end in an articulated manner to the ratchet lever (9) and the other end in an articulated manner to the toggle lever (12), which in turn is arranged at the other end in an articulated manner to the tilting cross member (1), and in the area of the toggle joint (14) between the toggle lever (11) and the toggle lever (12) an abutment plate (15) is provided which limits the bending movement of the two toggle levers (11) and (12). 2. Tilting traverse according to claim 1, characterized in that at the outermost end of the knee lever A spring (16) is connected to the lever (12) facing away from the knee joint (14), which pulls the knee levers (11, 12) into their "dead center position".
5 3. Tilting traverse according to claim 1 or 2, characterized by a traction means (17) which is connected to the toggle lever linkage (10). 4. Tilting traverse according to claim 3, characterized in that the traction means (17) is connected to the knee lever (12) in the region of the knee joint (14).
