Abstract

Anti-theft lock for vehicles, characterized by the fact that it comprises a rotating lock barrel and at one end of which a key can be received; locking means, requested by elastic means towards the barrel to a rest position, whose locking means are moved away from said barrel in the initial insertion of the key inside it, against the stress of the elastic means and from the rest position up to a displaced position; a plate member which extends substantially axially relative to the housing and carries at its end remote from or adjacent to the first end of the barrel, a pin member, said plate member being resiliently engaged towards an operating position in which the pin member is it engages with movable means that it is intended to block, in order to avoid movement thereof, the plate member incorporating a cam surface suitable for coupling with projection stop means of the barrel, and rotatable with the latter, so that, when the barrel is rotated by the key, the stop means move on the cam surface to move the plate member axially within the housing and against elastic stress, from the operating position to a withdrawn position, in which the pin member is disengaged from the movable means to allow their movement, while the reverse rotation of the key l It releases the stop means from the cam surface, the plate member being retained in its withdrawn position, by cooperation with the locking means until the key is completely withdrawn from the barrel, withdrawal which is accompanied by the return of the locking means from its displaced position to its rest position, and by the release of the plate member from the locking means whereby said plate member is returned by the elastic solution to its operating position in which a pin member engages with the means movable.
