Definitions

  • the invention relates to a sliding bolt lock with improved security.
  • Sliding bolt locks of this type have a movable groove in translation perpendicular to the direction of sliding of the bolt, against a compression spring, so as to effect a displacement in which the upper end of the groove bypasses a stop integral with the trunk of the lock.
  • the groove comprises a member cooperating with the stop integral with the trunk of the lock.
  • This stop integral with the trunk has a limited resistance and section, which constitutes a risk of break-in during a significant push on the bolt in the direction corresponding to the sliding return of the bolt in the lock.
  • This lock has a conformation which rests on the bolt in the position open from the lock and is braced behind the latch in the closed position of the lock, so as to oppose the return movement of the bolt.
  • This lock slides on the thickness of the bolt when the movement of lock lock and falls by gravity behind a latching hook after locking the lock. This lock is then lifted by the groove when unlocking of the lock, so as to allow the bolt to retract.
  • This device is entirely satisfactory to avoid any risk break-in during a significant push on the bolt in the direction corresponding to the sliding return of the bolt.
  • the object of the invention is to improve the security of sliding bolt locks, by creating a new simple lock with dimensions comparable to that of art anterior, and avoiding a break-in by passing through the barrel hole.
  • the subject of the invention is a sliding bolt lock with a movable groove against a compression spring, comprising a pivoting pawl intended for block the latch in the closed position of the lock, characterized in that the pawl rests on the groove in said closed position of the lock and in that the ratchet performs full swivel after full throat descent following removal of the barrel or similar operating member from the lock, to lock the lock in the locked position.
  • a lock 1 according to the invention is driven by a operating member such as a barrel, not shown, and comprises a closed trunk 2 by a cover 2a.
  • the safe 2 of the lock according to the invention contains a bolt 3 sliding
  • the bolt 3 has a control conformation 4 cooperating with the barrel not shown and a square 6 sliding in a light 6a of the trunk 2 of the lock.
  • the bolt 3 finally comprises an axis 5 cooperating with a groove 7.
  • This groove 7 includes a cleat 8 and a housing 9 for a spring 10 mounted in compression between the cleat 8 of the groove 7 and the axis 5 of the bolt 3.
  • the groove 7 comprises a retainer 11 able to retain the bolt 3 in the open or closed position of the lock.
  • This retaining member 11 is for example a portion in relief guided in a conformation 12, for example a U-shaped cut in the cover 2a of the chest 2.
  • a conformation 12 for example a U-shaped cut in the cover 2a of the chest 2.
  • the front branch of the U-shaped conformation or cutout 12 is longer than the rear branch of this conformation 12.
  • a pawl 13 is pivotally mounted in the manner of a lever around an axis 14 by means of two pins 15a, 15b of square section engaged in two holes 16a, 16b of the trunk 2.
  • the pawl 13, cut and folded in a metal sheet, comprises two substantially flat parts 17, 18, folded perpendicular to each other.
  • Part 17 of pawl 13 has a large section whose width roughly corresponds to the thickness of the bolt 3.
  • Part 18 of pawl 13 has a curved or circular contour intended to come into abutment against a screw or a member V secured to the lock2 of the lock, after complete rotation of the pawl 13 in the direction of arrow C.
  • the cover 2a of the lock according to the invention is not shown for the clarity of the drawing.
  • the lock according to the invention comprises a barrel 19 fixed in its housing by a screw 20.
  • the actuating barrel 19 comprises a bit 21 controlled by a key not shown.
  • the lock in the open position has its bolt 3 retained at the interior of the lock by the cooperation of the member 11 with the conformation 12 no shown, while the part 17 of the pawl 13 rests by gravity on the thickness of the bolt 3 with freedom of sliding.
  • the raised pawl 13 then rests by its part 17 on the thickness of the groove 7, sliding over the thickness of groove 7, when the rotation of the bit 21 in the direction of arrow 24 corresponding to the locking direction of the lock.
  • the pawl 13 falls by gravity, or possibly under the action of a spring prestressing not shown, in the direction of arrow 28 behind a curved recess 29 made on the bolt 3, so as to create a bracing behind this recess 29.
  • This bracing of the pawl 13 forming blocking lever is produced by the part 17 engaged behind the recess 29 of the bolt 3 in the locked position of figure 4.
  • the destruction of the barrel 19 results in a blockage of the lock according to the invention and prevents the bolt 3 from being pushed in the re-entrant direction, even in case of barrel rupture.
  • the pawl 13 is pivoted completely in the direction of the arrow C, to reach the stop position of the curved or circular outline of part 18 of the pawl 13 against a screw or a member V secured to the lock2 of the lock.
  • the pawl 13 in this stop position constitutes an obstacle which prevents re-entry of the bolt 3, completely blocking the lock in its position locking.
