摘要

The combination lock for a door handle is formed into a rigid and integrated unit with each section of the handle holding the lock together with the handle shaft. The combination lock wheels (4) have at least one specific recess where the door lock shrouding (9) can only be brought into the rest position when all the lock wheels are positioned at a given number, such as zero. The lock wheel shaft (6) has security pins (6c) in drillings between the rotary lock sleeves (6b) so that they can pass the passage openings in the intermediate members (5).
