Domaine technique de l'inventionTechnical field of the invention

La présente invention se rapporte au domaine général de l'agriculture et notamment de l'élevage de bovins, d'ovins, ou de caprins. Elle vise plus précisément un dispositif destiné à limiter les mouvements d'un animal qui est en train de manger.The present invention relates to the general field of agriculture and in particular the breeding of cattle, sheep or goats. It relates more specifically to a device intended to limit the movements of an animal which is in the process of eating.

Etat de la techniqueState of the art

Dans l'élevage de bovins notamment, il est connu d'utiliser des dispositifs, appelés cornadis, installés devant une auge et destinés à limiter les mouvements d'un animal qui est en train de manger. De manière classique, dans les cornadis connus, l'immobilisation de l'animal s'obtient par l'abaissement de sa tête dans un cadre constitué, d'une part, par une colonne du portique de stalle et, d'autre part, par un organe à balancier guidé librement sur le longeron supérieur dudit portique et monté de manière à pouvoir pivoter dans le plan de l'ouverture correspondante du portique grâce à une tringlerie de commande, de telle manière que sa partie supérieure s'écarte de ladite colonne du portique alors que sa partie inférieure s'en rapproche.In cattle breeding in particular, it is known to use devices, called yokes, installed in front of a trough and intended to limit the movements of an animal that is eating. Conventionally, in known headlocks, the immobilization of the animal is obtained by lowering its head in a frame consisting, on the one hand, of a column of the stall gantry and, on the other hand, by a pendulum member guided freely on the upper spar of said gantry and mounted so as to be able to pivot in the plane of the corresponding opening of the gantry thanks to a control linkage, in such a way that its upper part deviates from said column of the portico as its lower part approaches it.

Ces cornadis connus sont certes efficaces mais présentent un certains nombres d'inconvénients. Tout d'abord, ils ne respectent pas les mouvements naturels de l'animal, ce dernier devant lever sa tête pour l'engager dans l'espace délimité par la colonne du portique de stalle, l'organe à balancier et le longeron supérieur. Enfin, ces cornadis peuvent être dangereux pour l'animal, car ce dernier peut coincer son cou entre la colonne du portique de stalle et l'organe à balancier formant un V et finir par se blesser voire s'étrangler.These known yokes are certainly effective but have a certain number of drawbacks. First of all, they do not respect the natural movements of the animal, the latter having to raise its head to engage it in the space delimited by the column of the stall frame, the outrigger and the upper spar. Finally, these yokes can be dangerous for the animal, because the latter can trap its neck between the column of the stall frame and the pendulum member forming a V and end up being injured or even strangled.

Le but de la présente invention est donc de proposer une alternative aux cornadis connus qui soit pérenne, solide et facile à mettre en œuvre tout en étant sans risque pour l'animal et en respectant les mouvements naturels dudit animal.The object of the present invention is therefore to propose an alternative to the known yokes which is durable, solid and easy to implement while being without risk for the animal and respecting the natural movements of said animal.

Conformément à l’invention, il est donc proposé un cornadis remarquable en ce qu'il comporte :
- une pluralité de portiques plans verticaux agencés pour être disposés en enfilade les uns à côté des autres le long d'une auge d'une étable, chaque portique déterminant avec le sol et ledit portique adjacent ou poteau d'extrémité, un espace interne en forme de L,
- une trappe associée à chaque portique et mobile par rapport à ce dernier pour obturer ou non au moins la partie latérale inférieure dudit espace, et
- des moyens de blocage exclusivement mécaniques pour faire passer le cornadis de sa position "accès", dans laquelle chaque trappe peut au moins pivoter en direction de l'avant et de l'arrière du portique associé autour d'un axe globalement horizontal, à sa position "blocage", dans laquelle ledit pivotement est bloqué au moins en direction l'arrière dudit portique, et inversement.In accordance with the invention, there is therefore proposed a yoke remarkable in that it comprises:
- a plurality of vertical plane gantries arranged to be arranged in a row next to each other along a trough of a barn, each gantry determining with the ground and said adjacent gantry or end post, an internal space in l shape,
- a hatch associated with each gantry and movable relative to the latter to close or not at least the lower side part of said space, and
- exclusively mechanical blocking means to move the yoke from its "access" position, in which each hatch can at least pivot in the direction of the front and rear of the associated gantry around a generally horizontal axis, its "blocking" position, in which said pivoting is blocked at least towards the rear of said gantry, and vice versa.

Selon une première variante de réalisation, chaque portique comprend un premier montant vertical étant agencé pour être fixé par rapport au sol, une traverse supérieure s'étendant globalement perpendiculairement dudit premier montant depuis l'extrémité supérieure de ce dernier, un deuxième montant vertical s'étendant en direction du sol depuis l'extrémité libre de ladite traverse supérieure et une traverse médiane s'étendant globalement parallèlement à ladite traverse supérieure depuis l'extrémité inférieure dudit deuxième montant selon une direction opposée audit premier montant, l'extrémité de ladite traverse médiane opposée audit deuxième montant étant fixée sur le premier montant d'un portique adjacent ou sur l'extrémité supérieur d'un poteau d'extrémité.According to a first variant embodiment, each gantry comprises a first vertical upright being arranged to be fixed relative to the ground, an upper crosspiece extending generally perpendicularly from said first upright from the upper end of the latter, a second vertical upright extending in the direction of the ground from the free end of the said upper crosspiece and a central crosspiece extending generally parallel to the said upper crosspiece from the lower end of the said second upright in a direction opposite to the said first upright, the end of the said central crosspiece opposite said second upright being fixed to the first upright of an adjacent gantry or to the upper end of an end post.
