OBJECT OF THE INVENTION

The invention relates to an articulated connection between two rods, in particular for self-locking feed fences in stables for cattle.

STATE OF THE ART

In the known Selbstfangfreßgxttern are grid elements and rods made from pipes. The interception rods are attached to the fixed tube through a the bolts penetrating through the two tubes are directly connected to one another in an articulated manner and the boundary The swivel stroke in the rest position and catching position is carried out by a U-shaped, on the fixed bar attached sheet metal strips. This embodiment has the disadvantage that the high operational stresses often cause deformations at the bearing point, In addition, the bearing bore in the tubular rods results in an undesirable weakening which only occurs through correspondingly stronger embodiment of the whole Bars and rods could be compensated.

TASK

The invention is based on the object of creating an articulated connection between the lattice rods and the interception rods which, with normal cross-sectional dimensions, measurement of the bars is able to withstand all stresses and impairments occurring in operation reliably avoids deformations during operation.

SOLUTION OF THE TASK

In solving this problem, the invention is based on the consideration that weakened material for the articulated connection should be avoided at the hinge point for both the grid and the interception rods, in order to get by with the lowest possible cost of materials for these components. Based on this consideration are according to the invention for the articulation two special, on the rods to be connected to each other attachable joint body is provided, each consisting of a bearing eye for receiving a common joint bolt and there are two guide washers firmly connected to the bearing eyes, on which stops for Limitation of the swing stroke are attached in two predetermined angular limit positions. In this way

a connection between the interception rods and the grid that is sufficient for all stresses is guaranteed. There is also the advantage that normal grids can be retrofitted with interception rods can without fear of overstressing from the forces exerted by the cattle on the rods have to.

The guide disks are preferably used with their in the pivot plane of the interception rods lying guide surfaces as connecting elements between the bearing eyes and the bars; they can consist of rails running in the longitudinal direction of the rod, their backs serve to fix the rods. Preferably, L-profile-shaped rails are provided, whose to the bearing axis vertical legs form the guide washers, while the angular spaces of the rails are used to accommodate the rods. The joint body with their Bearing eyes, guide washers and stops each form a single casting.

The invention is illustrated in the drawing using the example of a self-locking feeding fence for cattle stalls. In such stables (cf.

DE-PS 21 53 863) the playpen floor S is through a separating base T and a grid G separated from a generally trough-shaped feed space. That Grille G consists of anchored firmly in the separating base T.

Joint perpendicular to the lattice plane with one of the fixed bars a of the lattice adjacent to the feeding gap are pivotally connected. These interception rods are provided at the top with obliquely angled ends b1, which in the Trapping position F, locking oneself in front of the neck of the eating animal, while the lower, straight ones Ends b2 of the. Neck underside of the animal from the area of the feeding gap are displaced, in which these ends b2 are in the standby position B.

The tentacles are provided with hooks h which can pivot to a limited extent for locking in the catch position F below, which fall behind locking rings r on a push rod d - if necessary by i80 ° rotation the push rod can be brought into or out of engagement individually - are arranged.

In this respect, the device corresponds to the conventional one described in the above patent specification 21 53 863 Embodiment. The grid can also be used with a be connected lower support tube and end post.

Special joint bodies 1, 2 are used for the joint connection with bearing eyes 1.1 and 2.1, hinge pins 3 provided, which to ensure an exact, to the plane of the eating

grid G parallel direction of the pivoting movement are provided with guide disks 1.2 and 2.2. These Guide disks are formed by one leg of L-shaped rails, their angular spaces to accommodate the tubular rods a and b. The joint bodies exist with their bearing eyes and guide washers each made from a single casting. To limit the swivel stroke it is with. The cast piece connected to the fixed lattice bar with molded stops 1.3 and 1.4 for the tentacle arm or the joint body 2 connected to the tentacle is provided.

Various modifications and other embodiments are possible within the scope of the invention; also is the invention mutatis mutandis applicable to the articulation of rods for other purposes.
