Abstract: In said devices the operation of the handle serves to open the door when the lock is in the unlocked position. The handle operation is achieved by means of an operating lever (30) and the rotation of the lock cylinder (60) is transferred to a carrier (45). According to the invention, the construction may be simplified and rendered flexible, whereby a control member (50) is used, which transmits the movement of the carrier (45) to the operating lever (30) of the handle. The operating lever (30) has an adjustable bearing position (31, 11 or 32, 12), which is determined in relation to the rotational position of the lock cylinder (60) by the control member (50). The transfer ratios (34.1 to 33.1 or 34.2 to 33.2) on the operating lever (30) are thus altered relative to a connector (40) leading to the lock. Although an identical operation of the handle occurs, differing working strokes (36) occur at the connector (40).
