  • the end of the link 36 is articulated to the locking device 8.
  • the locking device 8 comprises an electromagnet 51 whose movable core 52 is provided with a rod 53 which passes axially through the electromagnet, is movable parallel to the axis of the housing and enters a locking mechanism 54 which is controlled by the electromagnet 51.
  • This locking mechanism comprises a sleeve of rectangular cross section 55 mounted fixed in the housing.

  • This body 60 of substantially rectangular cross section comprises on the side of the electromagnet 51 a portion 63 of dimensions complementary to those of the internal space of the rod 56 and a portion 64 located on the side of the spring 61 whose height is reduced relative to the height of the hollow space, symmetrically with respect to the median plane of the rod.
  • the two portions 63 and 64 are connected by a middle portion 65 which has inclined surfaces which constitute ramps each cooperating with a small body of revolution, namely a small roller 68.
  • a lumen 70 through which the roller can partially penetrate into an advantageously triangular notch 71 formed in the wall of the sleeve 55.
  • the arrangement according to the invention is equipped with a superlocking device 72 with independent circuit, which is located in the housing in axial alignment with the electromagnet 51 and is designed to be able to block the movable core thereof.
  • This superlocking device 72 essentially comprises an electric motor 73 whose rotary output shaft 74 extends parallel to the axis of the housing and carries at its end an intermediate piece 75 which is rotationally integral with the output shaft 74 and carries at its free end a diametrical pin 76 which engages in an axial recess 78 in the form of a slot which passes diametrically through a screw 80.
  • the screw is rotationally integral with the intermediate piece 75 and thus with the output shaft 74 of the motor and axially movable relative to the latter.
  • the screw 80 passes axially through a nut 81 which is fixedly mounted in the housing, cooperating with the internal thread of this nut.
  • the end 82 of the screw which moves axially in response to the rotation of the output shaft of the motor is adapted to lock the mobile core 52 in its retracted position in the electromagnet 51.
  • the end 82 of the screw 80 allows the movable core 52 to come out of the magnet to occupy its position shown in FIGS. 2 and 5.
  • the screw 82 includes a flange 83 which allows the actuation of two contacts 85 and 86 at the end of the travel of the screw 80.
  • the latch device 1 To close the door, that is to say to pass from the state shown in FIG. 2 to that shown in FIG. 1, the latch device 1 is pushed into the space formed by the notches 14 of the jaws of blocking 11, 12. Under the effect of this device, the blocking jaw 11 rotates in the direction of arrow F1, the jaw 12 in the direction of arrow F2, this rotation being effected at the same angular speed as that jaw 11, but in the opposite direction.
  • This rotary movement of the jaw 12 is provided by the jaw 24 which moves in synchronism with the jaw 11.
  • the latter causes the pinion 30 to rotate in the direction of the arrow F3 which on the other hand causes the pinion 31 to rotate according to the arrow F4.
  • the pinion 31 rotates the pinion 32 in the direction of the arrow F5.
  • This pinion being integral in rotation with the plate 45 to which the link 34 is articulated, the rotation of the pinion causes the rectilinear axial movement of the rod 56 of the locking device, via the links 34, 35 and 36. Due to the multiplication effect of the pinion train, the rotation by an angle of 60 ° of the locking jaw 11 of the locking device 4 causes the pinion 32 and the hinge plate 45 to rotate at an angle of about 350 °, in the direction of arrow F5. Under the effect of this rotation, the rod 56 performs a back-and-forth movement which is symbolized by the arrow F6 and, due to the pivoting angle of 350 ° of the plate 45, stops in the position shown in Figure 1 in which the rod is fully inserted into the sleeve 55 of the locking device.
  • the locking arrangement according to the invention makes it possible, by playing on the difference in the primary teeth diameters, to increase the amplitude of rotation of the jaws and therefore to reduce the force of traction on the locking element, to obtain a high yield and precision of movement and thus to reduce noise and to avoid adjustment systems for positioning and to reduce the size of the arrangement.
