1. Lock with key, with double bolt closed position (2), consisting of a barrel (3), block cylinder, bolt carrier (2) and including one or more neck plates or blades (6 and 7) thrust outwards by one or more springs but retractable by action of the key, in such a way as to make the catch(es) (6' and 7') of the plates (6 and 7) enter the circle of the barrel (3), and allow rotation of the latter in one piece (1) comprising a body (8) holding the barrel (3) and in which it turns, characterized by the fact that, starting from the open position of the bolt (2), first notch (9, 13 and/or 15) made on the inside wall of the body (8), such inside wall does not form an abutment to the catch(es) (6', 7') whereas, by contrast, this same inside wall of the body (8) subsequently forms an abutment to a second notch (10, 14 and/or 16), first closed position, towards a third notch (11, 15 and/or 13), second closed position and conversely. |
