A quick coupler has a frame with a hook, and an operator movable control bar. The hook has a recess for receiving a hitch pin. A latch mechanism includes a latch, a one-piece trigger, a spring, and a stop fixed to the coupler frame. The latch is pivotally coupled to the frame and moves to open and closed positions permitting and preventing the hitch pin to move into and out of the hook recess. The trigger is pivotally coupled only to the latch and to the control bar. The trigger engages the hitch pin and moves the latch to the open position. When the hitch pin is in the hook recess, the stop engages the trigger and prevents the latch from moving to its open position. A central portion of the trigger is pivotally coupled to a central portion of the latch. A shoulder surface is formed in a lower end of the latch, and a tab projects from an end of the trigger. The tab engages the shoulder surface to limit pivoting of the latch to its open position when the trigger engages the stop. A latch spring is mounted on the latch and engages the frame and urges the latch to its closed position.

We claim: 1. In a quick coupler having a frame with a hook, and an operator movable control bar supported by the frame, the hook having a hook recess therein for receiving a hitch pin, a latch mechanism comprising: a latch pivotally supported by the frame and movable to an open position permitting the hitch pin to move into and out of the hook recess, and movable to a closed position preventing removal of the hitch pin from the hook recess, the latch having a shoulder surface formed in a lower end thereof; a stop fixed to the coupler frame; and a one-piece trigger pivotally coupled only to the latch and to the control bar, the trigger being engagable with the hitch pin and operable to move the latch to the open position in response to movement of the hitch pin towards the recess, and when the hitch pin is received by the hook recess, the stop engaging the trigger to prevent the trigger from allowing the latch to move to its open position, the trigger having a tab which projects from an end thereof, the tab being engagable with the shoulder surface to limit pivoting of the latch to its open position when the trigger is in engagement with the stop. 2. In a quick coupler having a frame with a hook, and an operator movable control bar supported by the frame, the hook having a hook recess therein for receiving a hitch pin, a latch mechanism comprising: a latch pivotally supported by the frame and movable to an open position permitting the hitch pin to move into and out of the hook recess, and movable to a closed position preventing removal of the hitch pin from the hook recess, the latch having a shoulder surface formed in a lower end thereof; a stop fixed to the coupler frame; and a trigger pivotally coupled only to the latch and to the control bar, the trigger being engagable with the hitch pin and operable to move the latch to the open position in response to movement of the hitch pin towards the recess, and when the hitch pin is received by the hook recess, the stop engaging the trigger to prevent the trigger from allowing the latch to move to its open position, the trigger having a tab which projects from an end thereof, the tab being engagable with the shoulder surface to limit pivoting of the latch to its open position when the trigger is in engagement with the stop.
