Definitions

  • the invention relates to a lock mechanism comprising a bolt actuated by the rotary bit of a key cylinder and a so-called "groove" locking piece making it possible to position the bolt stably and precisely along its trajectory in different predetermined positions. , the passage from one position to another corresponding to a turn of the key.
  • the invention relates more particularly to an improvement making it possible to avoid that the lock "false".
  • a conventional lock mechanism comprises, in the same housing or trunk, a key cylinder provided with a rotary bit, a bolt subject to move in a first direction and comprising drive crenellations called “barbs", on which acts the cylinder bit to move the bolt from one stable position to another, each turn of the key.
  • barbs drive crenellations
  • To define the stable positions of the bolt a so-called “groove” locking piece is provided on the side of the bolt. It is guided in a second direction perpendicular to the first and has a stop resiliently urged against an edge of the bolt on which several notches are provided. The engagement of the stop in one of the notches defines one of the above-mentioned stable positions.
  • Said groove further comprises a ramp cooperating with the bit so that the latter can lift the groove and consequently free the stop from a notch to allow the displacement of the bolt. It happens that depending on the wear of the parts or if some of them are biased in the housing, the movement of the bolt during a complete revolution of the bit is insufficient for the stop integral with the groove to engage in another notch. The lock is said to be "fake”.
  • the invention relates to an improvement making it possible to avoid this malfunction.
  • the basic idea of the invention is to build the bolt in two parts movable side by side with respect to each other, one of the parts comprising the aforementioned notches and the other part comprising the drive notches forming barbs.
  • the invention therefore relates to a lock mechanism comprising, in a box or trunk, a key cylinder provided with a bit, a bolt guided in a first direction and comprising drive crenellations forming barbs with which the said cooperates. bit for passing said bolt from a stable position to another in said first direction, a locking piece called "groove" adjoining said bolt and guided in a second direction perpendicular to the first and comprising, on the one hand, a stop resiliently urged against an edge of said bolt provided with several notches and capable of engaging in one of them so as to define a stable position mentioned above and, on the other hand, a ramp placed opposite the path of said bit for that the latter can move said groove in said second direction and release said stop from the notch where it is located, characterized in that said bolt comprises two elements movable relative to each other in said second direction, a main element carrying said notches and an auxiliary element carrying said barbs.
  • the two aforementioned elements constituting the bolt are preferably elastically urged by springs, one relative to the other in a way tending to move said notches away from said barbs.
  • the barbs remain in contact with the bit for a sufficient part of its stroke to ensure a desired movement of the whole bolt, at each turn of the key, allowing it to pass from a stable position to another defined , by cooperation of the groove stop with the neighboring notch.
  • the lock mechanism shown is arranged in a box or trunk 11 intended to be fixed or integrated into a door and comprises a key cylinder 12 provided with a rotary bit 13, a bolt 15 capable of being moved by the bit so that the end of said bolt can disengage from said trunk and a so-called "groove" locking piece 16 adjoining the bolt.
  • the latter moves and is guided in a first direction XX while said groove moves and is guided in a second direction YY perpendicular to the first.
  • the bolt has a massive part 17 and a relatively thin plate 18 extending said massive part while said groove 16 is also essentially defined in a metal plate attached to that of the bolt (see FIG. 4).
  • Two pins 19 are fixed to the internal wall of the housing.
  • Said groove 16 has two parallel oblong holes 20, elongated in the direction YY.
  • the groove 16 is engaged by its oblong holes 20 on the two pins 19, the assembly ensuring the guiding of the part in said second direction.
  • the bolt is, for its part, supported and guided in a rectangular opening 22 of the field wall of said trunk and by an oblong hole 24 elongated in the direction XX, made in the plate 18, the latter being engaged by this oblong hole on a pin 19 which already participates in guiding the groove.
  • the bolt as a whole, comprises drive crenellations forming "barbs" 25 with which said bit 13 cooperates when it is driven in rotation by the key actuating the cylinder and, on one edge of the plate 18, several notches 27 making it possible to determine several stable positions of the bolt.
  • the groove 16 comprises a stop 28 (produced by folding a tab of the plate forming said groove) capable of engaging in one of the notches 27 so as to define a stable position of the bolt.
  • a spring 30 fixed to a pin 32 secured to the housing bears against this stop and elastically urges the latter against the edge of the bolt comprising said notches 27.
  • the groove 16 has at its lower part a ramp 34, curved, placed in look at the path of the bit 13 so that the latter can move said groove in said second direction YY and consequently release the stop 28 from the notch 27 where it is located.
  • the bit 13 raises the groove 16 to unlock the bolt 15 by releasing the stop 28 from this notch and moves the bolt 15 in the direction XX by engaging in one of the notches defining said barbs .
  • the bolt 15 consists of two elements which are movable relative to one another in said second direction YY, respectively a main element 35 comprising the massive part 17 and the plate 18 in which are cut out said notches and an auxiliary element 36 carrying said drive crenellations forming barbs 25.
  • the main element 35 carries two pins 38 projecting on one of its lateral faces and the auxiliary element 36 has two holes oblong 39 oriented in the direction YY by which it is engaged on the two pins of the main element.
  • the latter carries a spring 40 in contact with a field of the auxiliary element 36 and urging the latter towards said bit 13.
