The present invention relates to an articulating and locking mechanism for a chassis of agricultural implements of broad working width. More particularly, the invention relates to a mechanism that enables alternation between an operation configuration and a rest configuration of agricultural implements, by articulating and locking movements of the chassis of said agricultural implement. Such an articulating and locking mechanism (6) chassis of agricultural implements is used on an agricultural implement (1 ) comprising at least one central chassis (4) and a side chassis (5) associated to each other. The mechanism (6) is capable of enabling or preventing angular movement between the central chassis (4) and the side chassis (5). In addition, the mechanism (6) comprises at least one extending arm (13), the first end of the extending arm (131) being associated to the side chassis (5); and further comprising at least one locking device (15) associated to a second end of the extending arm (132), the movement of the extending arm (13) in a first direction being capable of deactivating the locking device (15) to enable angular movement between the central chassis (40) and the side chassis (5), and the movement of the extending arm (13) in a second direction being capable of activating the locking device (15) to prevent angular movement between the central chassis (4) and the side chassis (5). The present invention also relates to an agricultural implement comprising the articulating and locking mechanism for chassis mentioned above.

La présente invention concerne un mécanisme d'articulation et de verrouillage pour châssis d'instruments agricoles de grande largeur de travail. L'invention concerne, plus précisément, un mécanisme permettant une alternance entre une configuration de fonctionnement et une configuration de repos pour des instruments agricoles, au moyen de mouvements d'articulation et de verrouillage du châssis dudit instrument agricole. Ledit mécanisme d'articulation et de verrouillage (6) pour châssis d'instrument agricole est utilisé sur un instrument agricole (1) comprenant au moins un châssis central (4) et un châssis latéral (5) associés l'un à l'autre. Le mécanisme (6) est capable de permettre ou de prévenir un mouvement angulaire entre le châssis central (4) et le châssis latéral (5). En outre, le mécanisme (6) comprend au moins un bras extensible (13), dont la première extrémité (131) est reliée au châssis latéral (5), et au moins un dispositif de verrouillage (15) relié à une seconde extrémité du bras extensible (132), le mouvement du bras extensible (13) dans une première direction étant capable de désactiver le dispositif de verrouillage (15) afin de permettre un mouvement angulaire entre le châssis central (40) et le châssis latéral (5), et le mouvement du bras extensible (13) dans une seconde direction étant capable d'activer le dispositif de verrouillage (15) pour prévenir tout mouvement angulaire entre le châssis central (4) et le châssis latéral (5). La présente invention concerne également un instrument agricole comprenant le mécanisme d'articulation et de verrouillage pour châssis précité.
