Doorleaf lock

A doorleaf lock, having a lock mechanism for governing a locking bolt and a catch bolt, which is controllable by means of a door handle, said catch bolt, in a neutral position defined by a spring means, extending with a non-circular bolt head through a non-circular opening in the lock front wall, abutting a catch means, and being displaceable into the lock, against the action of said spring means, during manipulation of said handle, wherein said catch means is accessible via a second opening in the front wall, and displaceable from its catch position by manipulation from the outside via the second opening so that the catch bolt, after said manipulation of the catch means, can be displaced with its bolt head out of the non-circular opening to the outside of the lock, enabling a turning of the catch bolt around its longitudinal axis wherein the catch means is pivotable around a pivot axis, which extends across the longitudinal axes of the bolts and the plane of the lock housing;

• wherein the pivot axis is placed adjacent the second opening;
• wherein the spring means comprises a hair pin spring, one limb of which rests against a foot section formed at the inner end of the bolt in the lock, and the second limb abuts the catch means keeping it in a neutral position in parallel with the longitudinal axis of the catch bolt while a ledge on the catch means forms a stop surface for the foot section;
• and wherein the catch means and an extension portion internal of the lock and constructed to cooperate with the catch means form a partition wall which is horizontally oriented when the lock is in an installed position.
