Definitions

  • the invention relates to an electronic lock.
  • Such locks are for example disclosed in patent applications EP 10161789 ( EP2248971A1 ) and EP 11175117 ( EP2 412 901A1 ).
  • the locking lever moves until it bears, on the other hand, on the fixed stop.
  • the locking lever is then stuck in its locking position.
  • This movement of the locking lever in response to the support of the locking member deforms its axis of rotation.
  • the deformation of the first axis increases the friction between this axis and the locking lever, which can then prevent the movement of the locking lever to its unlocked position.
  • repeated deformations of this axis of rotation can cause its irreversible deformation, or even rupture.
  • the invention aims to remedy this drawback.
  • the invention therefore relates to a lock according to claim 1.
  • Such a lock limits the mechanical deformation of the first axis in response to the support of the locking member. Indeed, in response to this support, the end of the first axis moves in the rail which allows the movement of the locking lever to the fixed stop while limiting or eliminating the deformation of the first axis. The strength and the life of such a lock are thus improved.
  • the embodiments of this lock may further comprise one or more of the features of the dependent claims.
  • the figure 1 represents a barrel 2 of a double barrel lock whose other barrel is not shown in the figure 1 .
  • This barrel 2 extends in depth along a direction Z perpendicular to horizontal and vertical directions, respectively X and Y.
  • the barrel 2 is for example identical to that described in the patent application EP11175117 except that it has a mechanism for protecting an axis of rotation of a locking lever. This mechanism is described with reference to figures 2 and following.
  • the two barrels are housed in a conventional manner in a door (not shown) and are arranged symmetrically with respect to the average plane P of the door.
  • the two barrels are positioned and connected in a conventional manner to one another by a connecting rod (not shown) which has in its middle a bulge serving as a spacer to maintain a predefined spacing between the two barrels.
  • a connecting rod (not shown) which has in its middle a bulge serving as a spacer to maintain a predefined spacing between the two barrels.
  • a bit (not shown) which can be rotated by a rotor 4 of one or the other of the two barrels when an appropriate key, for example a key 5 is introduced into a channel 6 of the rotor 4 and manually rotated by a user.
  • the bit When rotated by the key 5 and the rotor 4, the bit controls a conventional lock mechanism (not shown) which causes the displacement of at least one bolt of the lock in a direction allowing the opening of the lock. door or in a direction prohibiting the opening of the door according to the direction of rotation of the key 5.
  • a conventional lock mechanism (not shown) which causes the displacement of at least one bolt of the lock in a direction allowing the opening of the lock. door or in a direction prohibiting the opening of the door according to the direction of rotation of the key 5.
  • the rotor 4 of the barrel 2 is rotatably mounted in a profiled stator 7.
  • the stator 7 is itself housed in an outer sheath 8 having the same profile.
  • the stator 7 has a standardized profile, called "European”. Still in the example, the axis of rotation of the rotor 4 is parallel to the direction Z.
  • the barrel 2 conventionally comprises several pairs of stator and rotor pins, which are arranged in pairs, end to end, in corresponding pairs of aligned housings respectively formed in the stator 7 and in the rotor 4. arrangement of the rotor and stator pins is well known, this one has not been shown to simplify the figure 1 .
  • the key 5, which has for example a substantially rectangular cross section, has on at least one of its two large faces, preferably on its two large faces, indentations and / or reliefs which cooperate with the rotor pins.
  • the imprints and / or the reliefs are shaped and the lengths of the rotor pins are chosen so that, if a good key 5 is inserted into the channel 6 of the rotor 4, the interface between each rotor pin and the pin of associated stator is located exactly at the interface between the rotor 4 and the stator 7. Under these conditions, the rotor 4 can be rotated manually using the key 5, provided that a mechanism 9 electric lock is him - even in an unlocked state.
  • the mechanism 9 is here different from that described in the application EP11175117 to overcome the disadvantages mentioned above. It is described later.
  • the barrel 2 comprises an additional locking member 10 for preventing the rotor 4 from rotating as long as an appropriate digital code contained in a memory (not shown) housed in the key 5 has not been introduced into an electronic circuit 12 housed in the barrel 2.
  • the circuit 12 is disposed outside the barrel 2 to simplify the drawing. This circuit 12, when it receives the appropriate code, generates an electric unlock command. For example, it controls the mechanism 9 to enable the unlocking of the rotor 4.
  • the code is transmitted from the key 5 to the electronic circuit 12 of the lock via radio relay or via electrical contacts.
  • the key 5 is equipped with a transponder and the circuit 12 is equipped with a transponder reader.
  • the digital code contained in the memory of the key 5 is transmitted to the circuit 12.
  • the circuit 12 compares the transmitted code with at least one prerecorded code in a memory. In case of agreement between the two codes, the circuit 12 generates the electric unlocking command of the mechanism 9.
  • the additional locking member 10 is a stator pin which cooperates with a corresponding rotor pin 14 so that if the correct key is inserted into the channel 6, the interface between these two pins is exactly at the interface of the stator 7 and the rotor 4.
  • the locking member 10 is extended by a conical stud 16, with a top rounded, which is engaged in a corresponding frustoconical recess 18 formed in the rotor pin 14.
  • the member 10 is made of a magnetic material.
  • magnetic material denotes a material whose relative magnetic permeability is strictly greater than 1 and, preferably, greater than 100 or 1000.
  • the material is a ferromagnetic material such as steel.
  • the member 10 is movable between a locking position (represented on the figure 1 ) in which it is engaged with the rotor 4 to block its rotation and a retracted position in which it releases the rotation of the rotor 4.

  • the member 10 further comprises a transverse bar 24 which is formed integrally with the member 10 at the lower end thereof. One end of the bar 24 is shaped to form a heel 26.
  • the two sides of the bar 24 are engaged and guided in slots (not shown) formed in the wall of the housing 20. These slots prevent the organ 10 to rotate when it moves in the cylindrical housing 20.

  • the stop 40 is a lower part of the stator.
  • the lever 34 is shaped so that when in the locking position, in the absence of support of the member 10 on the lever 34, a clearance 42 (visible on the figure 5 ) remains between the end 36 of the lever 34 and the bar 24, and a clearance 44 (visible on the figure 5 ) remains between the end 38 and the stop 40.
  • These games 42 and 44 are sufficiently large to allow the lever 34 to rotate from its locking position to its unlocking position.
  • the shape and characteristics of the lever 34 may for example be identical to those described in more detail in the patent application. EP 1175117 .
