Abstract:
1. A hook coupling comprising; a hook body; a hook-in opening; a closure latch which can be adjusted between an open position, in which the hook-in opening is at least open to such an extent that a drawbar eye can be hooked in at the hook body, to establish a positive connection therewith, and a closed position in which the hook-in opening is closed at least to such an extent that the drawbar eye hooked in at the hook body is secured to stay thereon; a blocking lever which is pivotable between a blocking position, in which it blocks an adjustment of the closure latch from the closed position towards the open position, and a release position in which it permits an adjustment of the closure latch from the closed position towards the open position, wherein the blocking lever is mounted pivotably in the closure latch so as to be displaceable between the blocking position and the release position; and a triggering device which, in a basic position, whenever the blocking lever is in the blocking position, prevents displacement of the blocking lever into the release position, and which, when actuated out of the basic position, permits displacement of the blocking lever into the release position; wherein the triggering device comprises a triggering component which is mounted moveably on the closure latch, or on the hook body, or on a component connected rigidly to the hook body and which is moveable between the basic position and a triggering position in which the triggering component permits the displacement of the blocking lever into the release position; wherein the triggering component is provided on the closure latch or on the hook body or on a component connected rigidly to the hook body so that it is pivotable between the basic position and the triggering position; and wherein the blocking lever and the triggering component are pivotable in opposite directions.
