  • the invention also relates to the key for a lock controlled by magnets.
  • the document EP 1 482 108 describes a flat key with a notched profile, comprising a magnet for attracting, in one of the notches of the profile, a pin which is not spring-loaded.
  • the document EP 2 492 421 describes a flat key at the end of which is arranged a flat magnet, capable of separating, in the rotor, two magnets which attract each other while maintaining a pin in the keyway.
  • a flat magnet capable of separating, in the rotor, two magnets which attract each other while maintaining a pin in the keyway.
  • One of the two magnets moved apart by the key is integral with the pin and its movement releases the passage of the key.
  • the key has only one direction of insertion.
  • the document EP 0 571 311 describes a flat key carrying a magnet on each of its two side faces. Whichever way the key is inserted, one of the magnets is in position to push back a magnet, housed in the rotor, which in turn pushes a spring-biased pin out of the rotor.
  • the placement of the magnets on the side faces of the key is delicate, given their polarity which imposes their offset.
  • One of the aims of the invention is to propose a lock controlled by magnets which does not have the drawbacks mentioned.
  • the subject of the invention is a lock controlled by magnets, comprising a cylinder with a stator and rotor joined together by means of pins in the absence of a key, and a magnetic key for unlocking the rotor, in which the key bears, in its rod, a set of two magnets aligned on the same axis perpendicular to the axis of the rod of the key, the facing faces of the two magnets being of the same polarity, in which, in a first housing with an axis perpendicular to the axis of the rotor, the cylinder comprises a means for locking the rotor in the absence of a key, movable, on insertion of the key, by the magnets of the key rod, in which the axis of the rotor and the axis of the first housing of the cylinder define a first reference plane, the the axis of the key rod and the axis of the magnets of the key rod define a second reference plane, and after inserting the key into the

  • the key rod comprises a housing in which is inserted a capsule containing the magnets.
  • the cylinder comprises a second housing containing a pin biased by a spring and ensuring the release of the rotor when it is facing the capsule containing the magnets.
  • the capsule has an annular groove receiving a fixed pin.
  • the capsule has a lateral indentation providing relative movement with respect to a fixed pin.
  • the capsule comprises, on either side of its indentation, oblique faces.

  • the rotor has a polygonal housing at its end and the key rod has a polygonal end capable of being inserted into the polygonal housing of the rotor regardless of the direction of insertion of the key rod into the cylinder.
  • the means for locking the rotor in the absence of a key is a magnet whose face facing the axis of the rotor has the same polarity as the outer faces of the magnets of the key rod.
  • the first housing has a vertical axis and the magnet in said housing is subject to gravity alone and it is repelled by the magnets of the key stem.
  • the first housing has an axis with a different orientation from the vertical and the magnet in said housing is spring-loaded.

  • the magnets 3, 4 are housed in a non-magnetic capsule 5, made of plastic material for example, which has a annular groove 7 in the interval between magnets 3 and 4 ( Figure 3 ).
  • the magnets 3, 4 preferably have the same geometric axis. They are for example cylindrical, but can be of any shape.
  • the opposite faces of the magnets 3, 4 are of the same polarity, for example South (S).
  • the other faces of the magnets 3, 4, or external faces are also of the same polarity, for example North (N).
  • the housing 2 is a cylindrical passage in which the capsule 5 containing the two magnets 3, 4 is inserted.
  • a pin 6 is inserted into a passage 8 of axis perpendicular to the axis of the housing 2, and offset with respect to the axis of the housing 2, so that the pin 6 cooperates with the annular groove 7 to maintain the capsule 5 in the rod 1 of the key.
  • This maintenance is analyzed as a restraint, and not as a blocking of the capsule 5 in the housing 2 ( Figure 4 ), the whole of the capsule 5 and of the two magnets 3, 4 being endowed with a certain mobility in the housing 2 ( Picture 11 ).
  • the Figure 2 represents a round key rod 11, comprising near its end a cylindrical housing 2, with an axis perpendicular to the axis of the key rod 11, capable of receiving a capsule 5 containing two magnets 3, 4 having their faces in look of the same polarity, S for example.

  • the rotor 10 carries a fixed pin 12 for the orientation of the rod 11 of the round key ( Figures 9, 10 ).
  • the key rod 11 has a guide profile 13, 14 in the form of a wave, arranged symmetrically with respect to the reference plane of the key rod 11.
  • This guide profile is also symmetrical with respect to the plane perpendicular to the reference plane of the rod 11 of the key.
  • the sliding of the guide profile on the orientation pin ensures the rotation of the key so that at the end of the insertion stroke, the key is in the correct operating position.
  • the guide profile being symmetrical with respect to two perpendicular planes, the rotation of the key is a maximum of a quarter turn, and the key is reversible.
  • the key has no orientation imposed on the introduction into the rotor of the lock.
  • the rotor 10 is housed in a stator or dummy stator 15, to which it is secured in the absence of a key ( Figure 5 ).
  • a stator or dummy stator In the vicinity of its inner end, and on an axis perpendicular to the longitudinal axis of the rotor, are arranged, in the upper part a magnet 16 in a first housing 18 and in the lower part a pin 17 in a second housing 19.
  • the upper magnet 16 is located in the first housing 18 common to the stator 15 and to the rotor 10. This first housing 18 does not open into the central space of the rotor 10. As a result, the upper magnet 16 rests by gravity on the bottom of the first housing 18.
  • the upper magnet 16 fills the part of the first housing 18 located in the rotor 10 and partially the part of the first housing 18 located in the stator 15. In this rest position, the The upper magnet 16 prevents any rotation of the rotor 10 relative to the stator 15.
  • the magnet 16 is not subjected to gravity alone, but it is biased by a spring towards the bottom of the housing 18.
  • This embodiment variant makes it possible to arrange the housing 18 with an axis with a different orientation from the vertical.
  • the lower pin 17 is located in a second housing 19 common to the stator 15 and to the rotor 10.
  • This second housing 19 opens into the central space of the rotor 10, in the axis of the first housing 18.
  • the second housing 19 there is a conventional stack comprising a spring 20, capped by a cylindrical casing acting as a stator pin 21, and the pin 17 acting as a rotor pin.
  • a spring 20 When the key is introduced into the rotor 10, it pushes back the lower pin 17.
  • the capsule 5 containing the two magnets 3 and 4 When the key is in the correct position, the capsule 5 containing the two magnets 3 and 4 is opposite the pin 17, the tip of which comes into contact with one of the magnets 3, 4.
  • the pin 17 is then entirely in the rotor and the stator pin 21 is then entirely in the stator, and the rotor can turn.
  • the capsule 5 containing the two magnets 3 and 4 is provided, not with an annular groove 7, but with a lateral notch 27 of a certain height, providing it with relative movement with respect to the fixed pin 6.
  • the capsule 5 is movable in translation along the axis of the housing 2.
  • the capsule 5 protrudes from its housing 2, the upper edge of its notch 27 resting on the fixed pin 6. So that the key can be introduced without difficulty into the lock, the capsule 5 has, on either side of its notch 27, oblique faces 28 ensuring that it disappears in the key rod.
  • the capsule When the key reaches its final position corresponding to the Picture 11 , the capsule is placed on the lower pin 17 which urges it upwards under the action of its spring 20. To allow the capsule 5 to project above the key rod, the rotor 10 is provided with a recess under the housing 18 of the upper magnet 16.
  • the lower pin 17 pushes back the capsule 5 until the lower edge of the notch 27 bears against the fixed pin 6.
  • the magnet 3 is then close enough to the upper magnet 16 to push it back, possibly by compressing its spring.
  • the capsule 5 performs two functions. On the one hand, it maintains the lower pin 17 entirely in the rotor 10, on the other hand, it maintains the upper magnet 16 entirely in the stator 15. It thus controls two safety points to authorize the rotation of the rotor.
  • the rotor 10 comprises a third housing 25 receiving a pin 22 for securing the rotor 10 and the rod key 1 or 11.
  • This pin 22 is stressed by a spring 24 and protrudes into the central space of the rotor 10.
  • the spring 24, like the spring 20 of the lower pin 17, is capped by a cylindrical casing constituting a pin of stator, which ensures the blocking of the rotor 10 with respect to the stator 15 in the absence of a key.
  • the key rod 1 or 11 has two symmetrical notches 23, each of which can receive the pin 22 in a position allowing the rotation of the rotor 10 in the stator 15, and ensuring the joining of the key and the rotor to ensure this rotation ( Figure 6 ).
  • the rotor 10 between the third housing 25 of the pin 22 and the first housing 18 of the magnet 16, comprises several housings each receiving a pin, and the key rod comprises as many indentations to receive the tips of the pins.
  • the rotor 10 has a polygonal housing 26, for example hexagonal, adapted to receive the polygonal end 9 of a round key for example ( Picture 7 ).
  • the polygonal housing 26 also receives the polygonal end 9 of the key in its inverted position ( Picture 8 ).
  • the two magnets 3 and 4 of the key are mounted on the same geometric axis, with their facing faces of the same polarity (S for example) and their outer faces of the other polarity (N for example).
  • the upper magnet 16 has its face facing the key rod of the same polarity as the outer faces of the magnets of the rotor (N for example).
  • the upper magnet 16 is not positioned to allow free rotation of the rotor and the cylinder remains locked.
  • the upper magnet 16 can be free in its housing 18 and simply subjected to gravity.
  • the first housing 18 receives a means for locking the rotor in the absence of a key which, instead of being a magnet such as 16, is a ferromagnetic pin biased by a spring towards the stator.
  • a key which, instead of being a magnet such as 16, is a ferromagnetic pin biased by a spring towards the stator.
  • the magnets 3, 4 arrive opposite the ferromagnetic pin and attract it by compressing its spring, in a rotor release position.
  • the orientation pin 12 of the round key will ensure the correct positioning of the key by bringing the second reference plane into coincidence, defined by the axis of the key rod and the axis of the key magnets, with the first reference plane, of the rotor.
  • the introduction of the key into the lock is controlled by the coincidence between the notch 23 of the key rod and the pin 22 securing the rotor to the key.
