A motor vehicle door lock or the like comprises a locking mechanism for securing and releasing the door, operated by a lock which is disengageable from the locking mechanism. The disengageable lock comprises a stator, a tubular intermediate sleeve, a rotor operable by a key, and a control lever for actuating the locking mechanism. The control lever is coupled to the rotor through a driving sleeve. The lock also includes an indexer which is moveable axially between a rest, or engaged, position and a disengaged position when the intermediate sleeve is rotated during actuation of the rotor by an incorrect key. This axial movement of the indexer displaces the driving member axially to a position in which the driving member is prevented from rotating. The indexer is fixed in rotation to the intermediate sleeve, and is also free to rotate with respect to the stator when in the disengaged position.

[ What is claimed is:] [1.] A disconnectable lock for connection with a locking mechanism, the disconnectable lock comprising: a fixed stator defining an axis of the lock and having a front end and a rear end, a tubular intermediate sleeve fixed axially with respect to the stator but rotatable in the stator about the said axis; a rotor fixed axially in the intermediate sleeve and including releasable locking means for locking the rotor against rotation with respect to the intermediate sleeve, the rotor further having a keyhole and means mounting the said releasable locking means in the rotor for engagement of the locking means with a key when a key is inserted into the rotor through the keyhole, whereby when said key is a correct key, the key retracts the locking means into the rotor so as to enable the rotor to rotate freely with respect to the intermediate sleeve and with respect to the stator; a control lever at the front end of the stator; a driving member coupling the rotor to the control lever for rotational movement of the control lever by the rotor when the rotor is rotated with the said releasable locking means retracted into the rotor, the control lever being adapted to engage a said locking mechanism for actuation of the latter by said rotational movement of the control lever, the intermediate sleeve having means for engaging said releasable locking means in the absence of retraction of the releasable locking means into the rotor, so that when a said key is an incorrect key, rotation of the rotor thereby causes the intermediate sleeve to rotate with the rotor; and an indexer interposed between the intermediate sleeve and the driving member, for axial movement of the indexer between an engaged and rest position and a disengaged position of the indexer when the intermediate sleeve is rotated with respect to the stator by said rotation of the intermediate sleeve with the rotor in the presence of an incorrect key, whereby said axial movement of the indexer to said disengaged position displaces the driving member axially with respect to the rotor to a disengaged position of the driving member, in which the driving member is prevented from rotating further with respect to the stator, the indexer having means for coupling the indexer in rotation to the intermediate sleeve and the rotor when in its said disengaged position, in which the rotor is freely rotatable with respect to the stator, the said indexer comprising a ring element having rearwardly extending axial guide lugs, the intermediate sleeve having a front end, and further defining notches open in said front end of the sleeve for receiving the said guide lugs in the said disengaged position, the said ring element further carrying at least one catch projecting axially forward of the said ring element, the stator having a transverse face defining at least one axial aperture therein, the said at least one catch extending towards said transverse face of the stator whereby the or each said axial aperture of the stator receives a said catch when the indexer is in said rest position, the stator defining ramps flanking the or each said aperture therein, for guiding the said at least one catch out of the said at least one aperture when the intermediate sleeve is rotated about the said axis with respect to the stator, the driving member and indexer being fixed to each other in the axial direction; and a spring interposed between the rotor and the driving member for urging the driving member axially forward towards an engaged position of the driving member corresponding to the said rest position of the indexer, wherein the driving member comprises a rear portion and a front portion coaxial with the rear portion and disposed in front of the latter, the front portion being of smaller diameter than the rear portion, the said rear portion having a back end defining an external radial collar portion for engagement with the indexer whereby to couple the indexer with the driving member for relative movement in rotation but without relative axial movement being possible between the indexer and the driving member, the said back end of the driving member further having an outer cylindrical surface and at least one radial lug of the driving member projecting radially from the said cylindrical surface, and the stator having at least one recess for receiving the said at least one radial lug of the driving member when the driving member is in its disengaged position.
