Definitions

  • the lock 8 is described in the particular case where it is a door strip. Therefore, the reference numeral 8 is also used to designate the door strip.
  • Door 4 is located at the entrance to the home. This door 4 delimits the interior of the home from the exterior of the home. Subsequently, the terms “interior” and “exterior” are used to refer to what is located, respectively, inside and outside the home.
  • door 4 is a landing door of an apartment or a house or any other dwelling.
  • Door 4 has an interior face facing the interior of the home and, on the opposite side, an exterior face. The interior and exterior faces extend mainly in parallel vertical planes.
  • Door 4 is movable between an open position, shown in figure 1 , and a closed position. In the open position, a person can enter the home and therefore move from outside the home to the inside. Conversely, in the closed position, a person cannot enter the home.
  • Terminal 6 for example, is located outside the home and may be several kilometers away from home. To simplify the figure 1 , only one terminal 6 is shown. However, in practice, there are often several examples of terminal 6 that operate in the same way. Only terminal 6 is described in more detail below.
  • the interface 20 comprises, for example, one or more buttons that can be operated by the owner. Here, it comprises in particular a button 26 to trigger the sending of the unlocking command.
  • the transceiver 22 makes it possible to connect the terminal 6 to the strip 8 via a long-distance telecommunications network 28 such as a wireless telephone network or the Internet network.
  • Terminal 6 is, for example, the owner's smartphone.
  • Strip 8 is a multi-point door strip. Strip 8 is mounted, without any degree of freedom, on the inner face of door 4.
  • the strip 8 is in the form of a single piece inside which are housed the various components described with reference to the figure 2 .

  • the strip 8 can be installed on the inner face of a pre-existing door.
  • the bolt 36 is movable by the handle 38 from an extended position (shown in the figure 1 ) to a retracted position.
  • the bolt 36 is permanently pushed back to an extended position by a return spring.
  • the distal end of the bolt 36 is beveled so that when the door 4 is slammed from its open position to its closed position, by shape cooperation between the beveled end and an upright 40, the bolt 36 sinks inside the housing 30 against the force of the return spring in order to allow the door 4 to reach its closed position.
  • the upright 40 is fixed, without any degree of freedom, on the frame of the door 4.
  • Each of the deadbolts 42 is movable between an extended position and a retracted position. In the extended position, each bolt 42 is received in a corresponding cavity provided in the jamb 40 to lock the door 4 in its closed position. In its retracted position, each bolt 42 is retracted inside the housing 30 and located outside the cavity provided in the upright 40. Thus, when all the bolts 42 are in their retracted position, the door 4 is unlocked and can be freely moved from its closed position to its open position after pressing the handle 38.

  • the Y direction is directed from the inside of the home to the outside of the home. Terms such as “front” and “back” are defined with respect to the Y direction.
  • FIG. 1 schematically represents the interior architecture of the strip 8 as well as various elements connected to this strip 8.
  • the strip 8 comprises, mainly housed inside the housing 30, a bolt mechanism 50 and a system 52 for actuating the mechanism 50.
  • the mechanism 50 includes the bolts 42 as well as the linkage necessary to move them between their extended and retracted positions. However, in this embodiment, the mechanism 50 does not include the bolt 36.

  • the protruding state at least one bolt 42 is in its extended position.
  • all the bolts 42 are in their extended position.
  • the system 52 comprises a toothed wheel meshed with a rack of the bolt mechanism 50. When this toothed wheel rotates, in a first direction, this moves the mechanism 50 from its protruding state to its retracted state. retracted. When this same toothed wheel rotates in the opposite direction, this moves the mechanism 50 from the retracted state to its protruding state.
  • the system 52 does not allow the bolt 36 to be moved. The bolt 36 can only be moved using the handle 38.

  • Such unavailability may result from a failure of the motor 60 or another element of the actuation system 52. This unavailability may also result, for example, from a cut in the electrical power supply to the motor 60.
  • the cylinder 46 is a mechanical cylinder devoid of any electronic components that require power to operate.
  • the cylinder 46 is a European-format mechanical cylinder.
  • it comprises an inner half-cylinder and an outer half-cylinder 61 ( Figure 3 ) accessible, respectively, from the inner and outer sides of the door 4.

  • the pins of the first set are also known as "counter pins”.
  • the interfaces between the pins of the first and second sets of pins are all located at the interface between the rotor 62 and the stator 64, which releases rotation of the rotor 62.
  • the interface between the rotor 62 and the stator 64 is also known as the "break line".
  • the interfaces between the pins of the first and second sets of pins are not all located at the interface between the rotor 62 and the stator 64, which prevents rotation of the rotor 62.
  • the cylinder 46 also includes a bit 68.

  • the counter plate 202 can also be omitted. In this case, the front plate 200 rests directly on the outer face of the door 4.
  • the lock may take other forms than that of a door strip.
  • the lock is not a multi-point lock so that on the inside, it does not form a strip that extends over the entire height of the door.
  • the electric motor 60 is omitted. In this case, the movement of the bolt mechanism 50 can only be actuated using the cylinder 46.
  • Cylinder 46 can also be an electronic lock cylinder, for example, in European format.
  • the deduced rotational speed is taken equal to a number of complete revolutions made by the pellet 140 during a predetermined time interval.
  • the predetermined interval begins to be counted from a triggering event.
  • the triggering event is, in one possible embodiment, a new rotational movement of the pellet 140 which occurs after the module 90 has finished counting down the previous predetermined interval.
  • the triggering event is a rotation of the pellet 140 of at least ⁇ degrees, where ⁇ is a predetermined value greater than 5° or 10° or 90° so as not to take into account a slight accidental rotation of the pellet 140.
  • the measurements of the sensor 98 are used to count the number of complete revolutions of the pellet 140 during the predetermined interval.
  • Steps 312, 314 may be omitted. Similarly, steps 320, 322 may also be omitted.
  • the presence of the anti-drill pellet 140 makes the lock robust against break-in attempts by drilling the cylinder rotor. Measuring the rotation speed of this pellet 140 to detect such a break-in attempt makes it possible to quickly detect these break-in attempts with a high level of reliability even before the anti-drill pellet is completely destroyed or torn off.
  • the use of the return rod 126 makes it possible to house the angular sensor 98 on the inside of the door 4. This increases the robustness of the lock because the sensor 98 is thus very difficult to access from the outside of the door.
  • the cylinder protection part 130 if hammer blows are applied to the anti-drill pellet 140, the energy of these blows is mainly transmitted to the plate 120 of the lock housing 30 without passing through the cylinder 46. This therefore makes it more difficult to degrade or damage the cylinder 46 by applying such hammer blows to the anti-drill pellet 140.
  • Detecting the opening of the door in the absence of rotation of the pellet 140 and in the absence of receiving an unlocking command to actuate the motor 60 makes it possible to reliably detect an attempted break-in.
  • this arrangement makes it possible not to signal an attempted break-in when the lock is unlocked using the cylinder 46 normally or when the lock is unlocked in response to receiving an unlocking command without it being necessary to first deactivate countermeasures such as the alarm system.
