Title
(EN) A COUPLER
(FR) ATTELAGE
Abstract
(EN)
A coupler for coupling an implement having first and second spaced apart parallel pins, to the arm of a vehicle. The coupler has a body for attaching to the vehicle arm, a first fixed jaw, a movable second jaw facing away from the first jaw, and an actuator to selectively move the second jaw towards and away from the first jaw. The first jaw includes a lip forward of the seat for the first pin. A first locking member is pivotable between a locking position, in which a portion of the locking member protrudes into the opening of the first jaw, and an unlocked position. A second locking member is pivotable between a locking position in which a portion of the second locking member constricts the opening of the second jaw, and an unlocked position. Movement of the second jaw causes movement of the first locking member.

L'invention concerne un attelage destiné à accoupler un outil comprenant des première et deuxième broches parallèles espacées, au bras d'un véhicule. L'attelage comprend un corps destiné à être fixé au bras de véhicule, une première mâchoire fixe, une deuxième mâchoire mobile opposée à la première mâchoire, et un actionneur destiné à déplacer sélectivement la deuxième mâchoire vers et à l'écart de la première mâchoire. La première mâchoire comprend une lèvre en avant du siège pour la première broche. Un premier élément de verrouillage peut pivoter entre une position de verrouillage, dans laquelle une portion de l'élément de verrouillage fait saillie dans l'ouverture de la première mâchoire, et une position déverrouillée. Un deuxième élément de verrouillage peut pivoter entre une position de verrouillage, dans laquelle une portion du deuxième élément de verrouillage restreint l'ouverture de la deuxième mâchoire, et une position déverrouillée. Le mouvement de la deuxième mâchoire provoque le mouvement du premier élément de verrouillage.
