Definitions

  • the invention relates to a lock comprising a control member for a bolt and a mechanism for actuating this bolt using a key carrying a code, by means of a set of identification of code comprising lamellas of generally substantially rectangular shape, of the same dimensions, juxtaposed parallel with a determined pitch and movable behind the scenes in their longitudinal direction, each of these lamellas comprising, on a substantially rectilinear longitudinal side, a notch notched in one several locations determined along this side, the notched sides of all the lamellae being arranged substantially in the same plane perpendicular to the planes of the lamellae, so that, in - these notches brought into alignment by action of the key on the lamellae from their rest position, can engage, by a rectilinear drive edge which it comprises, a coupling member of the melles to the control member of the bolt, this coupling member being able to transmit to said control member the movement printed with the key.
  • the invention aims to improve a lock of this type
  • the key drives the slats which first slide in a positioning stroke where their notches are aligned if the key is suitable for the lock, then in a complementary stroke where, if the probe was able to engage by its drive edge in the aligned notches slats, these drive, via the feeler, the control member of the bolt in the sliding direction of the slats, in a direction tending to put the bolt in the open position, while a means of recall of the control member of the bolt in the opposite direction is provided to bring it back to the closed position, this means preferably not making it possible to move said member in the direction of opening.
  • Stop means should be provided to prevent the probe from moving in the sliding direction of the slats until its drive edge has engaged in the aligned notches of the slats.
  • the feeler remains immobilized without being able to drive the control member of the bolt until the alignment of said notches, which can only be obtained by means of a key carrying the correct coding.
  • movement of the feeler substantially perpendicular au'plan slat sides of the notch consists of a rocker motion about a hinge axis oriented parallel to this plane and perpendicularly to the • sliding direction of the slats, and movable in this direction.
  • the probe preferably comprises a second pair of lateral ears situated in the vicinity of its drive edge and engaged in a second pair of slots made in said fixed walls, each of these latter slots comprising a first part extending parallel to the direction of sliding of the slats and a second part, relatively short and oriented perpendicular to this direction, the corresponding ear of the second pair of the feeler located in this second part when the latter bears on the strips while they are at rest and their notches are not aligned, which prevents the feeler from moving.
  • a lock according to the invention does not lend itself to probing maneuvers in order to discover the coded combination that comprises all of the lamellae.
  • the driving-in movement thereof may be hampered by inadvertent catching of the notches of one or some of the strips on the drive edge of the probe in the event that this edge is affected by a slight deformation or a small offset from its theoretical rest configuration, so that the false key would fail to trigger the alarm device which is provided with the lock, provision should be made for the edge of the notch of each strip by which the drive edge of the probe is liable to be attacked is connected by a bevel to the longitudinal side of the strip in which the notch is made.
  • the lock according to the invention is particularly advantageous when it is designed to operate with the aid of a flat key, comprising a front edge provided with cutouts which reveal successive teeth and hollows therein according to a determined coding combination. ; such a key, inserted into the lock, is capable of selectively pushing, by said front edge, the strips of the identification assembly and of positioning them with their notches aligned, then of making them execute their complementary stroke.
  • the cutouts in the front twist of the key determine a binary coding there, each strip having its notch located in one of two locations determined along its length.
  • a lock according to the invention can be designed so that the key directly attacks the strips of the identification assembly, in their longitudinal sliding direction.
  • the coding notch that each lamella has on its longitudinal side facing the probe is located near its end opposite to that of attack by the key, so that the probe, whose drive edge is located in the vicinity notches of the slats, covers the latter only over a short length. If, in addition, provision is made for the second part of each of the slits of said second pair of slits to be continued by a third part, of short length, oriented parallel to the first part, it is possible to cause the probe to uncover and release completely the strips by temporarily placing it in an erasing position where it is retained by its second pair of ears engaged in said third part of the aforementioned slots.
  • the abovementioned stop, ensuring the maintenance of each strip,. may be formed by a projection of the corner gear provided in association with the strip. .
  • FIG. 3 shows schematically, in perspective, an alternative embodiment of the lock.
