Adjustment linkage for windows, doors or the like, composed of a lock-case-front rail 2, of an adjustment rod 3 and of a housing 4 which is fastened on said rail 2 and whose claws 18, engaging around the border of the rail 2 on three sides, are provided, on the claw web 20, with cutouts 24 for receiving the lugs 9 formed on the rail 2 by border clearances 8. The adjustment rod 3 is provided in the region of the housing 4 with through-passages 14 for the engagement of the teeth of a drive pinion 5 arranged in the housing 4. In order optionally also to be able to use the same embodiment of a lock-case-front rail 2 and an adjustment rod 3 for a passive adjustment linkage which does not have its own drive, it is proposed to use a pinion-free coupling housing 6 for connecting the adjustment rod 3 to the lock-case-front rail 2, which housing is likewise adapted, in the region of the claws 38, to the border clearances 8 of the rail 2. The coupling housing 6, in particular formed from plastic, may advantageously be provided with at least one pin 36 which can be sheared off and is intended for engagement into one of the through-passages 14 in the adjustment rods 3, as a result of which mounting is facilitated when fastening the adjustment linkage. <IMAGE> |
