Definitions

  • the invention relates to the field of secure key control and concerns a lock mechanism designed to prevent its opening when the outer portion is submitted to vibrations.
  • Electromechanical lock and key with identification code are widespread. Such a lock mechanism is disclosed in e.g. WO2014/016283A1 . They enable authorized key holders to have access to locked rooms if the identification code of the key corresponds to a predetermined code in relation with the electromechanical lock.
  • the key may be an ordinary locking key to insert into the lock or an access badge to pass in front of the lock.
  • the electromechanical lock comprises a processor configured to compare the identification code of the key with the predetermined code. If the identification code corresponds to the predetermined code, the electromechanical lock switches from its locked state to its unlocked state.
  • locks are formed with a body that can be easily unscrewed by a locksmith to facilitate rekeying.
  • the body has the function to lock and unlock the lock.
  • a lock body may be found under the form of a European cylinder (defined by the DIN18251).
  • a European cylinder is a type of lock cylinder.
  • a body may not be in the form of a cylinder.
  • a lock body may be inserted into a lock or a mortise lock or a slot-in lock. This function offers the advantage of allowing its change without altering the boltwork hardware. Removing the body typically requires only loosening a set screw, then sliding the body from the boltwork.
  • This type of electromechanical locks has the drawback that they are not totally safe. Indeed an ill-intentioned person may manage to unlock an existing lock by applying vibrations to the lock, for example by hitting the lock with a hammer. The internal mechanical elements of the lock slightly move because of the vibrations. While further submitted to vibrations, the internal mechanical elements may come into the position in which they cooperate to unlock the existing lock.
  • a new solution to overcome this drawback is a lock mechanism with an additional security feature, thus preventing the internal mechanical elements of the lock to cooperate when submitted to vibrations.
  • the subject of the invention is a lock mechanism comprising a housing, a lock clutch configured to cause the lock mechanism to switch between a locked state and an unlocked state according to a switching command received by the lock mechanism, a clutching mechanism mobile in rotation around a longitudinal axis and in translation with respect to the lock clutch according to the longitudinal axis and configured to be in an engaged position with the lock clutch so as to cause the lock mechanism to switch between the locked state and the unlocked state, or in a disengaged position from the lock clutch in the locked state, a first abutment against which the clutching mechanism abuts, the first abutment being mobile in translation with respect to the housing according to the longitudinal axis between the disengaged position and the engaged position according to the switching command, thus making the clutching mechanism mobile in translation between its disengaged position and its engaged position, a mechanical element extending along the longitudinal axis between the housing and the clutching mechanism, configured to maintain the clutching mechanism abutting against the first abutment in the engaged and disengaged
  • the mechanical element may be a spring, a piston, a rubber element, or a magnet.
  • the lock mechanism is configured to cooperate with at least one identification key having an identification code and to switch from the locked state to the unlocked state if the identification code of the at least one identification key is an authorized code of the lock mechanism.
  • the lock mechanism comprises a processor configured to read the identification code of the at least one identification key, determine if the identification code is an authorized code of the lock mechanism and deliver the switching command if the identification code of the at least one identification key is an authorized code of the lock mechanism.
  • the lock mechanism may comprise a motor configured to move the first abutment between the disengaged position and the engaged position according to the switching command.
  • the invention also relates to a locking system comprising the lock mechanism according to the invention and the at least one identification key, wherein the at least one identification key comprises a transmitter of the identification code and the lock mechanism comprises a receiver of the identification code.
  • the at least one identification key may be an electronic key or a remote control.
  • the at least one identification key is a smart phone configured to receive the identification code from an external connection or generate the identification code.
  • the invention also relates to a method for preventing a lock mechanism submitted to vibrations from switching between a locked state and an unlocked state, the lock mechanism comprising a lock clutch configured to cause the lock mechanism to switch between a locked state and an unlocked state, a clutching mechanism configured to be in an engaged position with the lock clutch so as to cause the lock mechanism to switch between the locked state and the unlocked state, or in a disengaged position from the lock clutch in the locked state, a mechanical element configured to absorb the mechanical energy due to vibrations, the method comprising a step of absorbing by the mechanical element the mechanical energy due to vibrations to which the lock mechanism is submitted in the disengaged position of the clutching mechanism in the locked state and retracting, so as to prevent the clutching mechanism from engaging with the lock clutch.
  • the mechanical element being a spring
  • the step of absorbing the vibrations comprises a step of retracting the spring
  • a door is an opening unit enabling the access to a room (or from a room to the outside) through an aperture.
  • the door is connected to a door frame that frames the aperture and is fixed to the walls around the aperture.
  • the door In an unlocked state of the door, the door is mobile in relation to the door frame, typically mobile in rotation around doors hinges (or in translation in the case the door and the door frame being configured to let the door slide in relation to a part of the door frame and the wall).
  • the door may be in an open configuration or a closed configuration. In the closed configuration, the door covers the aperture (i.e. no one can go through the aperture).
  • the door is equipped with a lock mechanism.
  • the lock mechanism has a latch that is either inserted into a slot of the door frame (the door is closed) or retracted in the door (the door is not more fixed to the door frame and may be open). In the closed configuration, the latch is inserted into the slot of the door frame.
  • a lock clutch is connected to the latch.
  • the lock clutch is usually engaged with both the indoor and outdoor door knobs. This enables a user to activate the lock clutch to cause the latch to move when a user moves one of the door knobs (or handles). Therefore a user has to move a door knob of the door to switch from the closed configuration of the door to the open configuration of the door. Indeed, the lock clutch being engaged with the knob, the movement of the knob generates a movement of the latch. Moving the door knob makes the latch retract into the door. The user can pull or push the door to open it.
  • the lock mechanism can be either in a locked state or an unlocked state.
  • the unlocked state corresponds to the case discussed above.
  • the door may be open by a user when activating a door knob and pushing or pulling the door.
  • the lock mechanism has a deadbolt entirely positioned inside the locking mechanism in the unlocked state. In the locked state, this deadbolt projects beyond the lock mechanism and is inserted into a slot of the door frame, thus locking the door to the frame.
  • the movement of the deadbolt can be mechanically obtained, for example by a rotation of a key inserted into the locking mechanism.
  • the rotation of the key clockwise, respectively anticlockwise, causes the deadbolt to translate either outside the lock mechanism to be inserted into the slot of the door frame, or inside the lock mechanism.
  • a user has to rotate the key with the corresponding rotation of the key inside the lock mechanism. Afterwards, to open the door, the user has to move a door knob of the door, as explained before.
  • a multi-point lock also known as a safety lock, provides extra security as it distributes the locking points (i.e. a plurality of deadbolts) over the entire door.
  • the most common multi-point lock is the three-point lock composed of a main deadbolt in the center and two other bolts at the top and at the bottom actuated by a rod.
  • Some multi-point locks may have up to ten locking points.
  • FIGS 1A, 1B, 1C schematically represent a first embodiment of a lock mechanism 10 according to the invention.
  • the lock mechanism 10 comprises a housing.
  • the housing is commonly a cylinder extending along a longitudinal axis Z.
  • the lock mechanism 10 comprises a lock clutch 11 configured to cause the lock mechanism 10 to switch between a locked state and an unlocked state according to a switching command 12 received by the lock mechanism 10.
  • the lock clutch 11 may for example be in a contact with the deadbolt.
  • the lock clutch 11 causes the deadbolt to translate beyond the lock mechanism 10 to insert into a slot of the door frame, so as to switch from the unlocked state to the locked state of the lock mechanism 10.
  • the lock clutch 11 causes the deadbolt to translate inside the lock mechanism 10, so as to switch from the locked state to the unlocked state of the lock mechanism 10.
  • the lock mechanism 10 comprises a clutching mechanism 13 mobile in rotation around a longitudinal axis Z and in translation with respect to the lock clutch 11 according to the longitudinal axis Z and configured to be in an engaged position with the lock clutch 11, so as to cause the lock mechanism 10 to switch between the locked state and the unlocked state, or in a disengaged position from the lock clutch 11 in the locked state.
  • the clutching mechanism 13 may be a star wheel or any gears.
  • the protrusions of the clutching mechanism 13 for example gear teeth
  • a rotation of the clutching mechanism 13 leads to a rotation of the lock clutch 11, to further translate the deadbolt, as mentioned before.
  • the disengaged position see Figure 1A
  • the protrusions of the clutching mechanism 13 are not in contact with the protrusions of the clutch lock 11. Therefore no rotation of the lock clutch 11 may occur.
  • the deadbolt cannot be translated.
  • the lock mechanism 10 further comprises a first abutment 14 against which the clutching mechanism 13 abuts.
  • the first abutment 14 is mobile in translation with respect to the housing according to the longitudinal axis Z between the disengaged position and the engaged position according to the unlocking command 12, thus making the clutching mechanism 13 mobile in translation between its disengaged position and its engaged position. Since the clutching mechanism 13 abuts against the first abutment 14, the mobility in translation of the first abutment 14 enables the clutching mechanism 13 to cooperate with the lock clutch 11. Since both the clutching mechanism 13 and the lock clutch 11 have protrusions (such as gear teeth), the mobility in rotation around the longitudinal axis Z of the clutching mechanism 13 enables its right positioning in relation to the lock clutch 11 to ensure their engagement with each other.
  • the lock mechanism 10 comprises a mechanical element 16 extending along the longitudinal axis Z between the housing and the clutching mechanism 13, configured to maintain the clutching mechanism 13 abutting against the first abutment 14.
  • the mechanical element 16 is configured to absorb vibrations to which the lock mechanism is submitted.
  • the mechanical element 16 may be a spring, a piston, a rubber element or a magnet. Any other element able to absorb vibrations generated outside the lock mechanism may replace one of the above-mentioned mechanical elements.
  • the lock mechanism 10 has the advantage that it cannot be unlocked by applying vibrations to the lock, for example by hitting the lock with a hammer. It is known that the internal mechanical elements of a lock slightly move when submitted to vibrations. While submitted to vibrations, the internal mechanical compounds of the lock mechanism 10 (i.e. the clutching mechanism 13 and the lock clutch 11) cannot come into the position in which they cooperate. Indeed, when the lock mechanism 10 is submitted to vibrations, the mechanical element 16 absorbs the mechanical energy due to the vibrations and retracts, as represented in Figure 1B .
  • the mechanical element 16 has mechanical features chosen so that the absorption is performed in a given range corresponding to the field of application as it is known by a person skilled in the art.
  • the lock mechanism according to the invention presents an additional security feature, all the more because the application of vibrations to the lock mechanism moves the clutching mechanism 13 away from the lock clutch 11.
  • the unlocking command 12 may result from an ordinary-looking key, the form of which being complementary to mechanical pieces inside the lock mechanism.
  • the rotation of the ordinary-looking key may lead to the displacement of an element in connection with the first abutment 14, so as to cause it to translate.

  • the lock mechanism 20 represented in Figures 2A, 2B, 2C is identical to the lock mechanism 10 represented in Figures 1A, 1B, 1C .
  • the lock mechanism 20 comprises the mechanical element 16 configured to absorb vibrations to which the lock mechanism 20 is submitted.
  • the mechanical element 16 may be a spring, a piston, a rubber element or a magnet. Any other element able to absorb vibrations generated outside the lock mechanism may replace one of the above-mentioned mechanical elements.
  • the mechanical element 16 absorbs the mechanical energy due to the vibrations and retracts, as represented in Figure 2B .
  • the lock mechanism 20 is configured to cooperate with at least one identification key 21 having an identification code 22 and to switch from the locked state to the unlocked state if the identification code 22 of the at least one identification key 21 is an authorized code 23 of the lock mechanism 20.
