Definitions

  • the present invention relates to a key-operated security lock, in particular for a motor vehicle.
  • the locks equipping the doors of current motor vehicles generally consist of a body pierced with a cylindrical bore in which a rotor secured to a rotor secured to a rod called a thresher, which drives an actuating rod of a lock mechanism.
  • Means retractable by means of a key are provided for locking the rotor in rotation relative to the body.
  • a lock comprising a body pierced with a cylindrical bore, a thresher housed at the bottom of the bore, movable in rotation around the axis of the body and integral with a rod actuating a lock mechanism, and means capable of being actuated by a key to drive the threshing machine in rotation.
  • the object of the present invention is to remedy the aforementioned drawbacks: it is aimed at a key-operated safety lock, in particular for a motor vehicle, which can hardly be torn off, which cannot be opened by the mere exercise of a couple on the rotor , nor by a direct action on the means of connection of the thresher to the lock mechanism and whose key profile has a large number of specific characteristics limiting as much as possible the opening of the lock by means of another key or any tool.
  • the means for locking in rotation of the thresher, retractable by means of the key consist of pistons mounted to slide in longitudinal holes drilled in the thresher and counter pistons mounted to slide in longitudinal housings drilled in the bottom. of the body with the same sections and the same arrangement as the holes of the thresher, a spring being placed at the bottom of each housing to normally bias each counter-piston in a position for which it is partially contained in its housing and partially in the hole corresponding to the thresher, the end of each piston opposite the counter-piston being capable of cooperating with a corresponding flat machined at the end of the key to place each counter-piston flush with the thresher-body interface.
  • the means for locking in translation of the rotor relative to the body are preferably constituted by flakes slidably mounted in radial housings drilled in the body extended by radial holes drilled in the rotor, each flake being normally biased by a spring in a position for which it is partially contained in its housing and in the corresponding hole of the rotor and being pierced with a hole capable of cooperating with a notch of the key to bring the straw in a position for which it is completely contained in the rotor.
  • the housings drilled in the body are circular grooves allowing rotation of the rotor relative to the body regardless of the position of the flakes in their housings
  • the disengageable means for blocking the rotation of the rotor by relative to the body being preferably elastic means allowing the disengagement of the rotor from a certain torque.
  • the housings drilled in the body comprise shoulders for blocking the flakes in rotation relative to the body, the flakes thus constituting both the means for blocking in translation and in rotation of the rotor with respect to the body.
  • the body advantageously consists of a fixed part and a mobile part called a stator, with an outside diameter slightly less than the inside diameter of the fixed part, locked in translation but movable in rotation relative to this. last and provided with rotation locking means, these means being preferably disengageable elastic means from a certain torque.
  • the lock shown in Figures 1 to 5 intended in particular for a motor vehicle door, comprises a body 1 pierced with a cylindrical bore 2 and terminated by a bottom 1 a in which is housed a thresher 3 in the form of a movable disc in rotation about the axis XX of the bore 2, and integral with drive means 3a of a rod 3b for actuating a lock mechanism, known per se and not shown.
  • the body 1 here consists of a fixed part 1 and a movable part 4, called a stator, with an outside diameter slightly less than the inside diameter of the fixed part 1 b and locked in translation relative to the latter between two shoulders 5 and 6.
  • the stator 4 is locked in rotation relative to the fixed part 1 b of the body 1 by a ball 7 which is held in a corresponding housing 8 of the body 1 b by means of a spring 9 but which is capable of coming out of the housing 8 from a certain torque, allowing the stator 4 to disengage from the fixed part 1b of the body 1.
  • a tubular rotor 10 of outside diameter slightly smaller than the inside diameter of the stator 4, is movable in axial translation relative to the stator 4 between a engaged position for which it is capable of driving the thresher 3 by means of a penetrating finger 11 in a notch 12 of the thresher 3, and a disengaged position.
  • Figures 1 and 2 show the rotor 10 in the disengaged position while Figure 3 shows the rotor in the engaged position.
  • Flakes 13 formed by plates are slidably mounted in radial housings 14 drilled in the stator 4 and extended by radial holes 15 drilled in the rotor 10.
  • Each flake 13 is normally biased by a spring 16 in a position for which it is partially contained in its housing 14 and in the corresponding hole 15 of the rotor 10, illustrated in Figure 1.
  • Each straw 13 is pierced with a hole 17 capable of cooperating with a notch 18 of the key 19 relating to the lock to bring the straw 13 in a position for which it is completely contained in the rotor 10 ( Figures 2 and 3).
  • the housings 14 have shoulders 14a for blocking the flakes 13 in rotation relative to the stator 4, the flakes 13 thus constituting means for blocking the rotor 10 both in translation and in rotation relative to the body 1.
  • Longitudinal holes 20 are drilled in the threshing machine 3 with the same sections and the same arrangement as longitudinal housings 21 drilled in the bottom 1a.
  • a spring 22 is placed in the bottom of each housing 21 and normally biases a piston 23 by means of a counter-piston 24 in a position for which its end opposite to the counter-piston 24 abuts against the end d 'a rod 25 secured to the bottom 1a. In this position, the counter-piston 24 is partially contained in the housing 21 and partially in the corresponding hole 20 of the thresher 3.
  • each piston 23 opposite the counter-piston 24 is capable of cooperating with a machined flat 26 at the end of the key 19 to place each counter-piston 24 flush with the thresher interface 3 - bottom 1a.
  • the end of the rod 25 is housed in a hole 27 provided at the end of the key 19.
  • the latter further comprises a notch 28 capable of cooperating with a finger 29 of the rotor 10 to drive the latter. ci in rotation.
  • the bore 2 is closed at its end opposite the thresher 3 by two flaps 30 and 31 which are each capable of being retracted in a housing 32, respectively 33, formed in the rotor 10, and which comprise elastic means formed here by torsion springs 30a and 31a, for returning to the closed position of the bore 2 when the key 19 is withdrawn.
  • the body 1 is provided at its end opposite the bottom 1a with a plastic cover 34 and a central part 35 made of a very resistant material, such as for example carbonitrided steel.
  • the entire lock is fixed by means not shown to a wall 36 such as a vehicle door.
  • this wall 36 is reinforced by a sheet 36a welded to the sheet 36.
  • the key 19 has been pressed in to a position for which the counter-pistons 24 are flush with the thresher interface 3 - bottom 1a, and the rotor 10 has undergone a longitudinal translation such as the finger 11 of the rotor 10 is located in the notch 12. It then suffices to rotate the key 19 to drive the rotor 10 which in turn drives the thresher 3 which actuates the lock mechanism via the rod 3b.
  • the body 1 no longer has a movable part or stator 4 such as that of Figures 1 to 5 and the radial housings 14 drilled in the body 1, here consist of circular grooves 14b allowing rotation of the rotor 10 relative to the body 1 whatever the position of the flakes 13 in their housings.
  • the rotor 10, which is therefore no longer locked in rotation by the flakes 13, is, in its disengaged position, locked in rotation relative to the body 1, by a ball 7a which is held in a corresponding longitudinal groove 8a of the body 1 by means of a spring 9a but which is capable of coming out of the groove 8a from a certain torque.
  • the groove 8a is terminated, at its end closest to the bottom of the body 1a, by a circular groove 8b which allows effortlessly the release in rotation of the rotor 10 relative to the body 1 when the rotor 10 is in the engaged drive position. of the threshing machine 3 in rotation.
  • the lock according to the invention can hardly be torn off because the wall 36 is reinforced in the vicinity of the lock by the sheet 36a.
  • the lock according to the invention therefore has the advantage of being able to be very difficult to open by means of a false key or of any tool and of being able to be very difficult to force or tear off.
  • a means of declutching in rotation (7, 8; 7a, 8a) prevents the opening of the lock without, however, damaging the latter.
  • the means for locking the rotor in rotation could consist of lugs cooperating with grooves made in the key or else by a set of pistons and counter-pistons.
