Abstract
A lever lock unit includes a housing, a dogging element adapted to actuate a lock bolt, a plurality of lever tumblers that are actuable via the dogging element and movable relative thereto, and a blocking element for blocking movement of the dogging element in the absence of a key or when the wrong key is inserted in the unit. The unit is characterized by a cradle accommodated in the dogging element and adapted to receive the lever tumblers. The dogging element is rotatable and is adapted so that when rotated, the cradle accommodated in the dogging element, and there with also the lever tumblers accomodated in the cradle, will be caused to move linearly in relation to the dogging element and in relation to a key inserted into the unit, for movement of the lever tumblers to a blocking element release position when the correct key is inserted.
