Definitions

• the present invention relates to a set of security key lock.
• a field of application envisaged is notably, but not exclusively, that of the building and more specifically that of the access doors to housing.
• Known key-lock assemblies known, for example of the "European cylinder” type, comprise a stator having a cylindrical housing, which stator comprises a plurality of locking pins pushed by springs and intended to extend partially to inside said cylindrical housing.
• Such a lock assembly also includes a rotor rotatably mounted within the cylindrical housing.
• the rotor comprises an axial passageway opening axially outwards on a key entrance, and a plurality of radial housings opening radially outwardly and each receiving a movable counter-pin in translation.
• the rotor is then released in rotation of the stator by means of a coded flat key.
• Document BE1010212 for example, describes the implementation of a flat key with the edge of the bit is notched.
• the calibrated notches correspond to the rotor, and when the bit is introduced through the keyway of the rotor, in the passageway, the cotter pins are spaced from the passageway and they push the same pins, so the contact zones between cotter pins and pins are extended in the joint plane of the stator and the rotor.
• the stator In order to make the lock assembly less easy to force, it is practiced in the stator at least two blind holes opening radially into the cylindrical housing.
• the rotor includes two balls and respectively a translationally movable locking member having a bearing end to be able to keep the balls protruding from the rotor, and an opposite end recessed. The balls then come to extend inside, blind holes so as to add additional rotational locking members of the rotor inside the stator.
• the bit of the flat key then comprises two lateral ribs interrupted to form a shoulder, and during the introduction of the bit inside the pathway, the two movable locking members then bear respectively on the shoulders, and they are driven in translation until their recessed ends respectively face balls. The latter can then retract inside the rotor when it is rotated inside the stator.
• a set of safety lock with a flat key comprising: a stator having a cylindrical housing and a blind hole opening radially in said cylindrical housing, said stator comprising a plurality of locking pins intended to extend inside said cylindrical housing; a rotor rotatably mounted within said cylindrical housing, said rotor comprising an axial passageway and a plurality of radial housings opening outwardly to permit said pins to be extended into said radial housings to maintain in position fixed said rotor with respect to said stator, said rotor further comprising a ball and a rotatable locking member for holding said ball projecting from said rotor while said ball extends within said blind hole; and, a flat key intended to be engaged inside said axial passage way in order to be able to push said pins outside said rotor, and simultaneously, controlling said locking member to allow said ball to retract within said rotor.
• said locking member is a cylinder of revolution.
• the locking member is a solid of revolution.
• the rotor has a cylindrical housing of revolution adapted in size to receive the locking member, and allow its rotation guidance.
• said locking member is rotatable about its axis of revolution.
• Figure 3B is a schematic detail view of Figure 3A;
• the rotor 18 is divided into two semicylindrical parts by the axial plane
• this second radial housing 66 has, towards the axial passageway 32 a reduced section creating a first stop shoulder 68.
• the counter-pin 64 then has a rod 70 surmounted by a head 72 forming a second shoulder d stop 74, which bears on the first stop shoulder 68 in order to retain the pin against 64 in translation towards the axial passageway 32.
• FIGS. 5A, 5B showing another embodiment of the invention for which only the elements of cooperation between the locking member and the contact piece, and the contact piece itself, have different shapes.
• the elements identical in their function to those among the elements represented in the preceding figures will have the same reference assigned a prime sign: "'".
