摘要

The locking device has an inner drive shaft (11) whose shaft seat (17) on the gear element (18) of the locking device (7) is accessible from the outside for an outer drive shaft (25) which can be driven circumferentially from outside. The inner drive shaft is movable in the longitudinal direction (12) from a function position to inside the room whilst the outer drive shaft when the inner drive shaft is on the room inside is supported on the shaft seat in the circumferential direction on the gear element (18) of the locking device and is in driving connection with the casement locking element of the locking device. The inner drive shaft can be moved between the function position and the inside of the room against the action of a retaining force.
