  • the lock shown in the figures and generally identified by the reference 1 comprises a hollow body generally identified by the reference 2.
  • This body 2 comprises a part of rectangular section 3 which is embedded and fixed through d an opening element such as a door 4 in which is formed a rectangular passage as well as a front wall 6 inclined up and down towards the outside and which has on its lower left part a projecting part 7, as well as a rear wall 8 set back with respect to the rear edges of the part of rectangular section 3.
  • the lock 1 has a member formed by a transverse shaft 9 which is mounted rotating in the projecting part 7 of the front wall 6 and in the rear wall 8. On the rear end of this shaft 9 is fixed radially a bolt 10 which , when the shaft 9 pivots 90 °, passes from a vertical opening position to a horizontal closing position of the door 4 in which it extends for example behind a fixed upright 11 only shown in the Figure 2.
  • the latter carries a boss 9a and the front or inner face of the rear wall 8 carries two bosses 8a and 8b against which the boss 9a abuts.
  • a recess 12 In the projecting part 7 of the front wall 6 of the housing 2 is formed a recess 12 with a flat bottom and concentric with the shaft 9.
  • an annular plate 13 is provided which is integral in rotation with the shaft 9 then a handle in the form of an operating button 14 which is rotatably mounted on the front end of the shaft 9 and which is held axially by a snap connection 15.
  • This operating button 14 has a rib on its front face radial gripping 16 located outside the projecting part 7 of the housing 2.
  • the front radial face of the plate 13, located opposite the rear radial face of the button 14, has a multiplicity of hemispherical notches 17 provided on the same circumference.
  • a recess 18 In the rear face of the button 14 is formed a recess 18 in which are arranged a spring 19 and a ball 20 which, under the effect of this spring 19, is pushed towards the plate 13 so as to partially engage in the notches 17 of this plate 13.
  • the set of notches 17, ball 20, spring 19 constitutes a disengageable elastic connection between the operating button 14 and the shaft 9.
  • a recess 21 in which are successively disposed a spring 22 and a ball 23 which under the effect of the spring 22 is pushed towards the face rear of the plate 13, this rear face of the plate 13 having two hemispherical notches 24 at 90 ° in which the ball 23 partially engages when the shaft 9 occupies its two extreme positions corresponding to the two extreme positions at 90 ° of the bolt 10.
  • a locking-unlocking mechanism generally identified by the reference 25 which is provided in the housing 2 between its front wall 6 and its rear wall 8.
  • This locking mechanism 25 comprises a lever 26 movable in a vertical plane perpendicular to the shaft 9.
  • This lever 26 has an arm 27 adjacent to the rear wall 8, the straight end farthest from the shaft 9 present laterally cylindrical bosses-28 forming axes rotating respectively in the front face 6 and in the rear face 8 and whose left end 29 is adapted to engage in a recess 30 provided at the periphery of the shaft 9.
  • the lever 26 also has, between its ends 28 and 29 an arm 32 which extends upwards and, from the upper end of this arm 32 a lateral arm 33 which extends horizontally away from the rear wall 8.
  • This electromagnet 34 comprises a magnet 35 of cylindrical section which extends perpendicular to the shaft 9 and the left end of which is carried by a projecting part 36 of the rear wall 8, this part 36 being situated above and at a distance from the shaft 9.
  • a coil holder 37 On the electromagnet 35, to the right of the door -magnet 36, is slidably mounted a coil holder 37 on which is wound a coil 38 and which has at its upper left part an inclined surface 39 forming a cam.
  • the coil holder 37 has a lateral finger 41 which is engaged in a longitudinal groove 42 provided in the rear face of the front wall 6 of the housing 2, this finger 41 sliding in this groove 42 during the sliding of the coil holder 37 on the magnet 35.
  • the lock 1 In its closed position visible in FIGS. 1 and 2, the lock 1 is in the following state: The shaft 9 is in its extreme position in which its boss 9a is in abutment against the boss 8b, the bolt 11 is horizontal in its closed position, the reel holder 37 is in its retracted position and the locking lever 26 is in its low position in which it prevents the shaft 9 from turning towards the open position of the bolt 10.
  • the shaft 9 does not move.
  • this operating button 14 rotates on the front end of the shaft 9 and the ball 20 passes from a notch 17 to the next notch 17, successively, by winning the force applied to it by the spring 19.
  • the shaft 9 has a weakening groove 43 provided behind the snap connection 15 and in front of the recess 30 of the shaft 9, in the plane of the flat bottom of the recess 12. Beyond a determined force on the operating button 14, other than a rotational force, is applied, the shaft 9 breaks at the level of the weakening rib 43 The operating button 14 separates but there is no longer any possible grip on the remaining front end of the shaft 9.
  • an electrical pulse is sent to the coil 38, for example from an electronic identification circuit not shown, connected to the coil 38 by a flexible electric wire 38a, this electronic circuit being for example placed in the housing 2 in rear of its rear wall 8 and subjected for example to an identification code introduced via a keyboard carried by the inclined external face of the front wall 6, the reel carrier 37 moves from its retracted position to its advanced position and raises the locking lever 26, thus releasing the shaft 9. This position in which the locking lever 26 is in its high position is visible in FIG. 3.
  • the electronic circuit sends a reverse pulse to the coil 38, the coil carrier 37 returns to its retracted position and the locking lever 26 is released. If the bolt 10 is still in its vertical open position, the underside of the locking arm 27 of the locking lever 26 comes to bear on the peripheral face of the shaft 9. As soon as the bolt 10 is brought back to its horizontal closed position by rotating the operating button 14 in the other direction, the locking lever 26 continues its downward movement and its left end 29 engages in the notch 30 of the shaft 9 and locks again the latter.
  • the lock 1 also comprises a security system generally identified by the reference 44, which makes it possible to prevent any displacement of the reel holder 37 from its retracted position as well as the rise of the locking lever 26, in particular in the event that the device carrying this lock 1 is shaken or tilted.
  • This system 44 comprises a pendulum element 45 which comprises a vertical arm 46 adjacent to the rear wall 8, the upper end of which has cylindrical lateral bosses 49 engaged respectively in the front wall 6 and in the rear wall 8 so as to constitute a articulation parallel to the shaft 9.
  • This arm 46 extends downwards towards the free end part of the arm 27 of the locking lever 26.
  • the lower end of the arm 46 of the pendulum element 45 is located just opposite a recess 50 provided in the arm 27 of the locking lever 26 in which it engages when the locking lever 26 is raised, without preventing its movement.
  • the angular movement of a few degrees of the pendulum element 50, in a vertical plane perpendicular to the shaft 9 and above the arm 27, is limited on either side of its vertical position by two stops 53 and 54 provided projecting from the rear wall 8.
  • the reel holder 37 has, at its lower left part, a transverse projecting part 51 and the arm 27 of the locking lever 26 has a lateral arm 52, which are arranged so as to form stops preventing the locking lever 26 from rising from its shaft locking position 9 when the reel holder 37 is in its retracted position, the transverse stop 51 of the reel holder 37 emerging from the transverse arm 52 of the locking lever 26 after a short stroke of the reel holder 37, as soon as the cam follower arm 33 reaches cam 39.
  • the lower end of the pendulum element 45 comes above one of the edges 50a or 50b of the recess 50 provided in the arm 27 of the locking lever 26 and prevents the latter from rising, this rise being further prevented by virtue of the corresponding stops 51 and 52 provided respectively on the reel holder 37 and on the locking lever 26, the cam 39 abuts against the cam follower arm 33 and the movement of the spool holder 37 towards its advanced position is thus stopped, the locking lever 26 being unable to rise and therefore remaining in its position for locking the shaft 9.
