Abstract: A locking mechanism to secure a coupler's jaw, and a coupler incorporating the locking mechanism.

Abstract: A coupler to secure a work attachment to a work vehicle is disclosed. The work attachment includes a first pin and a second pin, while the coupler body has a first engagement portion which is configured to accept the first pin and a second engagement portion configured to accept the second pin. The coupler body has a guide and a slider configured to slide along the guide. The body of the slider includes a first locking portion and a second locking portion. The coupler has a trigger located on the coupler body such that the trigger is released by contact with the second pin, and a first actuator that is activated by release of the trigger. When the trigger is released, the first actuator moves the slider along the guide into an engaged position where the first locking portion engages and retains the first pin in the first engagement portion of the coupler body and the second locking portion engages and retains the second pin in the second engagement portion of the coupler body at the same time.

Abstract: A coupler for attaching an implement to a machine, the coupler including a body portion, a first jaw configured to engage a first attachment portion associated with the implement; a moveable jaw configured to engage a second attachment portion associated with the implement; and a first sensor located on the body portion configured to detect the presence of the implement adjacent to the body portion and to indicate one of a safe position in which the implement is securely held by the coupler and an unsafe position in which the implement is not securely held by the coupler.

Abstract: There is provided a locking mechanism to secure a coupler's jaw, and a coupler incorporating the locking mechanism.

Abstract: A method of releasing a work attachment from a coupler (2), wherein the work attachment is secured to the coupler via two pins held within two jaws (5, 7), the method including the steps of: (a) moving a jaw (7) to release a first pin (b) changing the orientation of the coupler (2) and work attachment relative to each other (c) moving the jaw (7) in the opposite direction to that in step (a); characterised by the step of: (d) moving the jaw (7) in the opposite direction to that in step (c) characterised in that the action of step (c) moves a safety link (17) to a release position, thereby allowing a locking portion (10) to release a second pin from a jaw in step (d).
