Row uncoupling device for cattle stalls

There are. Row decoupling devices known for cattle stalls) which each consist of a large number of individual parts, whereby these must be guided or »stored, whereby the. Risk of plague rust and thus failure, for example in the In the event of a fire.

In a known device are over one with thumb levers provided actuation by means of the thumb lever vertically slidable multi-leg bolt arranged, each with one leg acts as a guide piece and the other as a locking piece, if now a large number of such devices from one ¥ elle must be operated out, and the animals pull chains on them when panic, then unlocking is no longer reliably possible, because then an enormously high frictional resistance has to be overcome * This difficulty is compounded by an unavoidable one Increased soiling and rust formation.

To avoid these disadvantages, serial decoupling devices proposed according to the invention for cattle sheds that the end links or suspension rings of the chains on pivoting · The levers can be suspended, the levers can be detached or uncoupled by pivoting the levers, the one adjoining the suspension ring The end of the chain is looped around the actuating shaft from below, into which the lever can be hung »

Further details of the invention are to be found at the end of the description to be found in the following subclaims.

In the housing designated 1, a continuous strong shaft 2 is rotatably mounted below, on which short locking levers 3 are attached. Above that, a lever 5 suspended approximately vertically by its own weight is rotatably mounted on a bolt k in the housing 1 by means of a socket 6 * The locking lever 3 is fastened to the actuating shaft by screws. This can fill the free housing space between the bearings with its width, as shown in FIGS. 1 and 2, or it can be designed with a narrow locking piece 3 ". In the second case, the upwardly tapered locking piece 3 "can penetrate into the chain ring 8 and the determination of the position of the chain ring thus produced prevents unintentional uncoupling. The corresponding shape of the locking piece 3" of the locking lever 3 is shown in Fig. k .

When the device is closed, i.e. when the locking levers 3 are swiveled in, the levers 5 hanging downwards are moved backwards. towards the side, that is, pushed into the housing and thus secured or locked. In this position the animals can be pushed in of the chain ring 8 between the head of the locking lever 3 and that of the lever 5 are coupled. On the reverse Individual animals can be uncoupled using the operator. At the end of an actuating shaft 2, the locking position is of the operating lever 9 by a lock 10

According to the invention, there is still another embodiment. It essentially only consists of a housing 1, an actuating shaft 2 and the lever 3 on which the link or the ring 8 of the chain is hooked around the actuating shaft 2 from below. This greatly simplified series decoupling device fulfills the same effect Purpose like the previously complicated devices and also has much less friction and therefore fewer possibilities of failure on, <

The advantages of the series decoupling device g according to the invention _{are that it can be actuated with the lowest possible expenditure of force Q} and that it remains fully functional even when it is dirty and completely functional.
