ABSTRACT:
A cylinder lock whose stator is a longitudinal groove and whose rotary cylinder has a key receiving slit, two series of seatings and two orthogonal slits; a series of sliders pushed by springs is inserted, with mobility in two directions, into the first series of seatings of the cylinder and cooperates with a key, and each slider is provided with projections and with a member for sliding engagement; a series of tumblers is slidingly inserted into the second series of seatings of the cylinder, and each tumbler is provided with recesses turned towards the sliders and with at least one recess at the opposite side; a stop bar pushed by springs is inserted into an orthogonal slit and is provided with projections turned towards the tumblers and with a continuous projection suitable for being inserted into the groove of the stator; and a translation bar pushed by springs is inserted into the other orthogonal slit of the cylinder, engages the members for sliding engagement of the sliders and is provided with a continuous projection suitable for being inserted into the groove of the stator; the parts are coordinated in such a manner that the stop bar immobilizes the tumblers until its continuous projection penetrates into the groove of the stator, and that the sliders engage the tumblers until the continuous projection of the translation bar penetrates into the groove of the stator, thus giving rise to a condition in which the key can be replaced by a different key.
