Definitions

• the present invention relates to a lock comprising a locking-unlocking mechanism using an electromagnet of a connecting or adapting member to connect on the one hand a handle or other actuating means and on the other hand at least one bolt.
• said mechanism comprises an auxiliary element adapted to in one position be engaged with said member and in another position to be released from this member, a return means acting on said auxiliary element so as to urge it towards the one of its positions, an electromagnet comprising a magnet and a coil, a cam and a cam follower, one of which is carried by the movable element of said electromagnet and the other by said auxiliary element and adapted to cooperate so that when the mobile element of the electromagnet passes from a first position to a second position the auxiliary element passes from one of its positions to its other position against said return means, and vice versa.
• said handle is connected to said member by means of disengageable means allowing the rotation of this handle relative to this member when the torque applied to it is greater than a determined value.
• said member may comprise a shaft coaxial with said handle, this handle and this shaft having two opposite faces between which are provided elastic means ensuring the disengagement of said handle when the torque applied to it is greater than a determined value.
• one of said faces preferably has notches while the other carries elastic means penetrating into these notches.
• said mechanism comprises means for preventing the displacement of said auxiliary element before said cam and said cam follower cooperate to move this auxiliary element from one of its positions to its other position.
• said mechanism comprises at least one pendulum element allowing the movement of said auxiliary element from one of its positions only when they are in determined positions.
• said member consists of a shaft, said auxiliary element consists of an articulated lever which can occupy a first position in which it prevents rotation of said shaft and a second position in which this shaft is free, and said return element biases this articulated lever towards its first position, the mobile element of said electromagnet being adapted to move linearly and horizontally.
• said lever can extend perpendicular to said shaft and the movable element of said electromagnet is adapted to move perpendicular to said shaft.
• said mechanism can advantageously comprise a pendulum element allowing movement of said lever from its first position to its second position only when they are in determined relative positions.
• the movable member of said electromagnet and said lever can advantageously carry stops which prevent the displacement of said lever before said cam and said cam follower cooperate to move this lever from its first position to second position.
• FIG. 1 shows a transverse and vertical section along I-I of Figure 2 of a lock according to the present invention
• - Figure 2 shows a longitudinal section along II-II of the lock of Figure 1, its mechanism being in the locked position;
• FIG. 3 shows a view corresponding to Figure 2 of the lock of Figure 1, its mechanism being in the unlocked position;
• FIG. 1 shows an interior rear view of the lock shown in Figure 1, the latter being inclined.
• 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 5 as well as a front wall
• the lock 1 has a member formed by a transverse shaft 9 which is mounted to rotate in the projecting part
• a recess 12 In the projecting part 7 of the front wall 6 of the housing 2 is housed 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
• a shaft 9 is associated with 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 furthest from the shaft 9 presents 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. Lateral to the vertical arm 32 and below the transverse arm 33 is provided an electromagnet generally identified by the reference 34.
• 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 located above and at a distance from the shaft 9.
• 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 to the open position of the bolt 10. If we try to rotate the shaft 9 using the operating button 14, the shaft 9 does not move. When the blow applied to the operating button 14 is greater than a determined value, 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 take on the remaining front end of the shaft 9. If an electrical pulse is sent to the coil
• 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 further comprises a security system generally identified by the reference 44, which makes it possible to prevent any movement 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 includes a pendulum element 45 which includes a vertical arm 46 adjacent to the rear wall 8, the upper end of which has cylindrical lateral bosses
• the reel carrier 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 the 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 the corresponding stops 51 and 52 provided respectively on the reel holder 37 and on the locking lever 26, the cam 39 comes into abutment against the cam follower arm 33 and the movement of the reel holder 37 towards its advanced position is thus stopped, the locking lever 26 being unable to rise and therefore remaining in its shaft locking position 9.
