A multicoupling device for lines, especially hydraulic lines, wherein first and second coupling parts (7,8) are provided with a plug connector (5) or a bushing (6) for coupling units (1,2) whose number corresponds to the number of connections to be produced. The coupling units (1,2) are embodied in the form of a self-locking lock-in coupling with a locking sleeve (9) which can be displaced in relation to the bushing (6). The two coupling parts (7,8) can be brought together by means of a switching element (10) and can be pressed apart and are mutually lockable in the coupling position. The locking sleeves (9) interact with a common switch plate (11). The switching element (10) is rotatably mounted on an axis (12) on the switch plate (11). The switch plate (11) can be adjusted in relation to one (8) of the two coupling parts (7,8) in the direction of closure or opening of the coupling units (1,2). The two coupling parts (7,8) can be moved by the switching element (10), which is mounted on the switch plate (11), by engagement via curved engagement slots and by bolts (14) protruding on the other coupling parts (7), in relation to each other in a closing and opening position.

L'invention concerne un dispositif à raccords multiples pour des conduites, notamment des conduites hydrauliques. Un certain nombre d'unités de raccordement (1, 2) correspondant au nombre de raccordements à effectuer comporte des premiers et des deuxièmes éléments de raccordement (7, 8) avec une fiche mâle (5) ou une fiche femelle (6). Les unités de raccordement (1, 2) sont de type raccord à blocage automatique comportant un manchon de blocage (9) mobile relativement à la fiche femelle (6). Un élément de commutation (10) permet de rassembler et de désaccoupler les deux éléments de raccordement (7, 8) et de les bloquer en position d'accouplement. Les manchons de blocage (9) coopèrent avec une plaque de commutation (11) commune à toutes les unités de raccordement (1, 2). L'élément de commutation (10) est logé pivotant sur un axe (12) de la plaque de commutation (11), laquelle est mobile relativement à un (8) des éléments de raccordement (7, 8) dans le sens d'ouverture et de fermeture des unités de raccordement (1, 2). Les deux éléments de raccordement (7, 8) sont mobiles l'un par rapport à l'autre dans une position de fermeture et d'ouverture, au moyen de l'élément de commutation (10) logé sur la plaque de commutation (11) avec solidarisation par des fentes d'engrènement incurvées et au moyen de boulons (14) en saillie sur l'autre élément de raccordement (7).
