Definitions

  • the invention relates to a system for actuating a bolt mechanism.
  • the invention also relates to a door strip comprising this actuation system as well as an assembly for producing this actuation system.
  • the actuation systems are used in locks and, in particular, in electronic door locks.
  • the actuation systems make it possible to move the bolt mechanism between a protruding state and a retracted state.
  • the bolts of the bolt mechanism are in an extended position in which they lock the door in a closed position by formal cooperation with a door frame.
  • the bolts In the retracted state, the bolts are in a retracted position in which the door can freely be moved from its closed position to its open position.
  • Known actuation systems include in particular an electric motor which makes it possible, when an unlocking command is received, to automatically move the bolt mechanism from its protruding state to its retracted state.
  • These known actuation systems also include a mechanical cylinder to be able to open the door even in the event of failure of the electric motor.
  • the invention aims to remedy at least one of the disadvantages of the actuation system of a bolt mechanism. FR2696493A1 .
  • FIG 1 represents a door 2 of a dwelling.
  • This door 2 can be moved between an open position, shown on the figure 1 , and a closed position. In the open position, access to the interior of the housing is possible. In the closed position, access to the interior of this housing is prohibited.
  • this electronic lock is fixed without any degree of freedom on door 2.
  • this electronic lock is a multi-point door strip 4 mounted on the interior side of door 2.
  • This strip 4 is in the form of a housing 6 inside which a bolt mechanism 10 is housed ( figure 2 ) and a system 12 ( figure 2 ) for actuating the mechanism 10.
  • the strip 4 also includes a handle 14 which allows the door 2 to be moved between its open and closed positions.
  • the housing 6 is here fixed along the vertical edge of the door 2 located on the side opposite the hinges.
  • the bolt mechanism 10 includes bolts. Each of these bolts can be moved between an extended position and a retracted position. In the extended position, each bolt is received in a corresponding cavity arranged in a frame or a frame 14 fixed without any degree of freedom on the frame, to lock the door 2 in its closed position. In its retracted position, each bolt is pressed inside the housing 6 and located outside the cavity provided in the frame 14. Thus, when all the bolts are in their retracted position, the door 2 can be freely moved from its position. closed position to its open position.
  • each bolt 20 is shown in their extended position to make them more visible even if the door 2 is in its open position.
  • each bolt 20 is a cylindrical bar movable in translation between its extended and retracted positions.
  • the actuation system 12 makes it possible to move the mechanism 10 from a protruding state to a retracted state and vice versa.
  • the protruding state at least one bolt 20 is in its extended position.
  • all the bolts 20 are in their extended position.
  • the system 12 comprises a toothed wheel meshed with a rack of the bolt mechanism 10. When this toothed wheel turns, in a first direction, this moves the mechanism 10 from its protruding state to its retracted state. When this same toothed wheel turns in the opposite direction, this moves the mechanism 10 from the retracted state to its protruding state.
  • the system 12 comprises an electric motor 30 ( figure 2 ) and an emergency device 32. On the figure 1 , only the device 32 is visible.
  • the device 32 is called “emergency” because it is mainly intended to move the mechanism 10 from its protruding state to its retracted state in the event of unavailability of the electric motor 30.
  • the motor 30 is said to be “unavailable” when it cannot not be used to move the mechanism 10 from its protruding state to its retracted state.
  • Such unavailability may result from a breakdown of the motor 30 or from a another element of the actuation system 12. This unavailability can also result, for example, from a cut in the electrical power supply to the motor 30.
  • FIG 1 also represents an orthogonal coordinate system XYZ.
  • the Z direction of this mark corresponds to the vertical.
  • the X and Y directions are horizontal.
  • the X direction is parallel to the vertical plane in which the door mainly extends.
  • the direction X is directed from the edge of the door along which the strip 4 is fixed, towards the hinges of this door.
  • the Y direction is directed from the inner side to the outer side of door 2.
  • the figures 3 to 8 are oriented relative to this same XYZ reference.
  • the device 32 is a mechanical cylinder devoid of any electronic component which requires power to operate.
  • the unlocking member 46 is a bit which moves in rotation. Subsequently, the same numerical references 32 and 46 are used to designate, respectively, this mechanical cylinder and this bit.
  • the fixing mechanism comprises a screw whose screw head is only accessible from the vertical edge of the door 2 or from a vertical face of the housing 6 parallel to this vertical edge of the door 2
  • this screw is received in a hole made in the door 2 or the housing 6 and which opens into the housing capable of receiving the cylinder.
  • the end of this screw is screwed into the stator 42 of the cylinder 32 to retain it, without any degree of freedom, inside the housing.
  • the cylinder 32 comprises a rotor 40 rotatably mounted inside the fixed stator 42.
  • the stator 42 is fixed, by the fixing mechanism, without any degree of freedom, on the door 2.
  • the rotor 40 comprises a channel 44 of key which opens on the interior side and the exterior side. This channel 44 is intended to receive a key.
  • the rotor 40 can be rotated around its axis of rotation only when an authorized key is introduced inside the channel 44 and then turned.
  • An authorized key is a key authorized to move the mechanism 10 to its retracted state.
  • the rotor 40 is blocked from rotating and cannot rotate around its rotation axis.
  • the access authorization mechanism of the cylinder 32 comprises a first set of pins movable in translation inside the stator 42 and, opposite, a second set of pins movable in translation inside the rotor 40 by the key inserted into the channel 44.
  • the pins of the first set are also known under the term “counter pins”.
  • the interfaces between the pins of the first and second sets of pins are all located at the interface between the rotor 40 and the stator 42, which releases the rotation of the rotor 40.
  • the interface between the rotor 40 and the stator 42 is also known under the term "hyphenation line".
  • the interfaces between the pins of the first and second sets of pins are not all located at level of the interface between the rotor 40 and the stator 42, which prevents the rotation of the rotor 40 and therefore the rotation of the bit 46.
  • the rotor 40 When the rotation of the rotor 40 is prohibited by the first and second sets of pins, the rotor 40 is in a particular angular position relative to the stator 42. This particular angular position is subsequently called the rest position. A key can be completely inserted or removed from channel 44 only when rotor 40 is in this rest position. As soon as the rotor 40 is angularly offset from this rest position, generally, the key cannot be removed from the channel 44. Subsequently, these positions of the rotor 40 angularly offset from the rest position are called “ rotated positions”.
  • the bit 46 is rotated by the rotor 40 when this rotor is turned. It is the rotation of this bit 46 which makes it possible to activate the movement of the mechanism 10 towards its retracted state.
  • the motor 30 includes a drive shaft 48. When the motor 30 is controlled to move the mechanism 10 to its retracted state, it is the rotation of the shaft 48 which activates the movement of the mechanism 10.
  • the system 12 includes a control unit 50.
  • This unit 50 is able to receive an unlocking command and, in response, to control the motor 30 so that the shaft 48 rotates in a first direction which moves the mechanism 10 towards its retracted state.
  • the unit 50 comprises a programmable microprocessor 52 and a non-volatile memory 54 comprising the instructions to be executed by the microprocessor 52.
  • the memory 54 comprises all of the instructions and data necessary to execute the different functions described in this text.
  • the different components of the unit 50 are connected to each other via an information transmission bus 58.
  • the unit 50 comprises a transmitter/receiver 56 capable of establishing a wireless communication link with a remote mobile terminal 55 via a long-distance telecommunications network 59 such as a wireless telephone network.
  • a transmitter/receiver 56 capable of establishing a wireless communication link with a remote mobile terminal 55 via a long-distance telecommunications network 59 such as a wireless telephone network.
  • the terminal 55 executes an application which acquires an unlocking command via a man-machine interface then transmits this unlocking command to the transmitter/receiver 56.
  • the terminal 55 is a smartphone.
  • the unit 50 is also capable of controlling the motor 30 to rotate the shaft 48 in the opposite direction and thus return the mechanism 10 to its protruding state. For example, after a predetermined period of time has elapsed since the unit 50 received the unlock command, the unit 50 automatically controls the motor 30 to return the mechanism 10 to its protruding state if the door 2 is in its closed position.
  • the system 12 includes an opening sensor 60 capable of detecting if the door 2 is in its closed position. This sensor 60 is connected to the unit 50.
  • the system 12 comprises an output shaft 70 and a mechanism 72 for mechanically coupling the bit 46 and the shaft 48 to this shaft 70 to cause it to rotate.
  • the shaft 70 moves the mechanism 10 from its protruding state to its retracted state when it is turned in one direction and from its retracted state to its protruding state when it is turned in the opposite direction.
  • a differential is usually used to distribute the rotational speed of one input shaft to two output shafts.
  • the 80 differential is used differently. More precisely, when the shaft 84 is blocked in rotation, it transmits the rotational movement of the shaft 82 to the shaft 70. Conversely, when the shaft 82 is blocked in rotation, the differential 80 transmits the rotational movement from shaft 84 to shaft 70.
  • the differential 80 is an epicyclic differential. Such a differential is formed using gear wheels. An example of embodiment of this differential 80 is described below with reference to the figures 3 to 8 .
  • the differential 80 also makes it possible to amplify the torque of the pin 46 and therefore to obtain a greater torque on the shaft 70. This makes it possible to increase the force exerted on the bolt mechanism 10 to facilitate its movement.
  • connection 86 systematically transmits the rotational movement of the shaft 48 to the shaft 82.
  • this connection 86 includes an immobilizing device 90.
  • the device 90 makes it possible to block the rotation of the shaft 82 when the shaft 84 is rotated by the bit 46.
  • the device 90 authorizes the transmission of the rotational movement only in the direction going from shaft 48 towards shaft 82 and, conversely, prevents the transmission of a rotational movement from shaft 82 towards shaft 48.
  • the mechanical connection 88 transmits the rotational movement of the bit 46 to the shaft 84.
  • this connection 88 comprises an immobilizing device 92.
  • the device 92 makes it possible to block the rotation of the shaft 84 when the shaft 82 is rotated by the motor 30.
  • the device 92 authorizes the transmission of the rotational movement only in the direction going from the bit 46 towards the shaft 84 and, conversely, prevents the transmission of a rotational movement from the shaft 84 to the bit 46.
  • the connection 88 is also made using toothed wheels.
  • connection 88 additionally comprises an electronic device 94 for blocking the rotation of the shaft 84.
  • the device 94 can be moved reversibly between an active state and a passive state. In the active state, it blocks the rotation of shaft 84. In the passive state, they release the rotation of shaft 84.
  • the device 92 does not prevent the rotor 40 from turning, using the authorized key, from its rest position to a turned position and therefore rotating the shaft 84. Thus, the device 92 does not allow not to condemn the use of cylinder 32.
  • the device 94 makes it possible to prohibit the use of the cylinder 32. To this end, it prohibits the rotation of the shaft 84 even with the aid of an authorized key. Furthermore, here, by blocking the rotation of the shaft 84, the device 94 also blocks the rotation of the rotor 40.
  • the device 94 is able to condemn the use of the cylinder 32, and therefore to move in its active state, in response to receipt of a condemnation command. Then, the device 94 remains in its active state until a rehabilitation command is received. In response to receipt of an order for rehabilitation, the device 94 moves from its active state to its passive state.
  • the device 94 comprises the control unit 50 and the unit 50 is configured to receive, via the transmitter/receiver 56, a condemnation command and, alternately, a rehabilitation command transmitted by the terminal 55.
  • the use of the cylinder 32 can be condemned and, alternately, rehabilitated remotely. This feature is useful, for example, in the event that the authorized key is lost.
  • the user detects the loss of the authorized key he interacts with the terminal 55 to transmit the locking command. Next, it replaces cylinder 32 with a mechanical cylinder having a different authorized key. Finally, it interacts with terminal 55 to transmit the rehabilitation command.
  • the cylinder 32 can be replaced by any mechanical cylinder in the European format commonly marketed. This is made possible by the fact that the devices 92 and 94 are located outside the cylinder 32, that is to say that none of the parts of the devices 92 and 94 are received, at least in part, in this cylinder 32. Thus, the mechanical cylinder 32 has nothing specific compared to the mechanical cylinder currently marketed. Cylinder 32 is therefore interchangeable with mechanical cylinders currently marketed in European format which have the same length.
  • the endless screw 100 is fixed, without any degree of freedom, on the shaft 48 and rotates on itself around an axis 104 of rotation coincident with the axis of rotation of the shaft 48.
  • the crown 102 rotates on itself around an axis 106 of rotation perpendicular to the axis 104.
  • the axis 106 is parallel to the direction Y.
  • the crown 102 also constitutes the input shaft 82 of the differential 80. Under these conditions, the crown 102 is blocked in rotation as long as the shaft 48 is not rotated.
  • THE figures 4 to 7 represent a detailed example of the mechanical connection 88.
  • the figures 5 and 6 correspond to the states of the connection 88 when the rotor 40 is, respectively, in its rest position and a rotated position.
  • Figure 7 illustrates the active state of the immobilization device 92 reached when the shaft 82 is rotated while the rotor 40 is in a rotated position.
  • the blocking device 94 has not been shown on this Figure 7 .
  • the crown 110 rotates on itself around an axis 114 ( Fig. 4 ) of rotation coincident with the axis of rotation of the bit 46. More precisely, the cylinder 32 has a notch crossed by the bit 46 when the latter is rotated by the rotor 40. When the bit 46 rotates, its distal end describes a circle, of radius R 46 , centered on the axis 114. The crown 110 also passes through this notch when it rotates on itself. For this purpose, the exterior radius R ext110 of the ring 110 is less than or equal to the radius R 46 . In addition, the crown 110 includes a radial slot 116 ( Fig. 4 ) inside which the bit 46 is received.
  • the internal radius R int110 of the crown 110 and the width of the slot 116 are sufficiently large so that the cylinder 32 can be inserted inside the crown 110 by a translation movement in the Y direction when the bit 46 is received at the inside the cylinder notch.
  • the crown 110 is held in place inside the system 12, even in absence of cylinder 32.
  • the crown 110 comprises, in addition to external teeth, a smooth circular ring 118 whose external radius is equal to R 46 .
  • the system 12 comprises a circular hole, not shown, centered on the axis 114 and inside which the ring 118 is received.
  • the diameter of this circular hole is chosen to keep the ring 118 centered on the axis 114 even in absence of the cylinder 32 while allowing the rotational movement of the ring 118 around the axis 114.
  • the radius of the circular hole is slightly greater than the diameter R 46 .
  • the wheel 120 turns on itself around an axis 126 of rotation parallel to the axis 114. It has teeth shaped to mesh with the teeth of the crown 110.
  • the teeth of the crown 110 and of the wheel 120 are shaped to allow rotation of the bit 46 over more than one complete revolution.
  • the teeth of the wheel 120 have a space 128 ( Fig. 4 ) authorizing the passage of the bit 46 without blocking its rotation around the axis 114.
  • Finger 122 is eccentric with respect to axis 126.
  • finger 122 is a cylinder, of circular section, whose axis extends parallel to axis 126.
  • the Maltese cross 124 has radial grooves 130 each capable of receiving the finger 122. When the finger 122 is received inside one of these grooves 130, the wheel 120 rotates the Maltese cross 124. Here , each time that the crown 110 rotates the Maltese cross 124, this Maltese cross 124 rotates by 40 degrees around an axis of rotation coincident with the axis 106 of rotation of the Maltese cross 124.
  • the Maltese cross 124 additionally constitutes the input shaft 84 of the differential 80.
  • the stop 140 is fixed, without any degree of freedom, on a vertical face of the wheel 120.
  • the stop 140 has a convex cylindrical face 144 whose directing curve is an arc of a circle centered on the axis 126.
  • Each concave face 142 is located between two grooves 130 and turned towards the stop 140.
  • the concave faces 142 and the convex face 144 are shaped to block, by shape cooperation with each other, any transmission of the rotation of the Maltese cross 124 towards the bit 46.
  • the convex face 144 is fitted inside one of the concave faces 142 as illustrated in the figure 5 .
  • the finger 122 is outside the grooves 130. This prevents any transmission of a rotational movement from the Maltese cross 124 to the wheel 120.
  • the rotation of the wheel 120 around its axis 126 remains authorized.
  • the rotational movement of the bit 46 causes the rotation of the wheel 120 and therefore of the Maltese cross 124.
  • the mechanism 112 also does not make it possible to transmit a rotational movement of the Maltese cross 124 towards bit 46. Indeed, in this case, as illustrated on the Figure 7 , one of the concave faces 142 abuts against one end of the convex face 144 which blocks the rotation of the Maltese cross 124. On the other hand, in the position of the Figure 7 , the rotation of the wheel 120 around its axis 126 remains authorized. Thus, the rotational movement of the bit 46 causes the rotation of the wheel 120 and therefore of the Maltese cross 124.
  • the position represented on the Figure 7 can be achieved, for example, when an authorized key is forgotten in channel 44 and the rotor is in a rotated position and then the shaft 82 is rotated by the motor 30.
  • the stopper 150 can be moved reversibly between an active position and an inactive position. In the active position, the stopper 150 prohibits the rotation of the Maltese cross 124 even using an authorized key. In the inactive position, the stopper 150 releases the rotation of the Maltese cross 124.
  • the stopper 150 is here a pawn comprising a tip 154 which, in its active position shown on the Figure 5 , is introduced between two teeth of the wheel 120. In the inactive position, this tip 154 is not engaged with the teeth of the wheel 120. The stopper 150 moves between these active and inactive positions in translation along 'an axis which intersects axis 126.
  • the actuator 152 moves the stopper 150 between its active and inactive positions in response to a corresponding command transmitted by the control unit 50.
  • the actuator 152 is a monostable actuator which includes a return spring which permanently urges the stopper 150 towards its inactive position.
  • the actuator 152 in response to receipt of a locking command, the actuator 152 is powered to move the stopper 150 from its inactive position to its active position. Then, the power supply to the actuator 152 is maintained until a rehabilitation command is received. If when moving the stopper 150 towards its active position, the tip 154 comes into abutment, for example, on the top of a tooth, then the stopper 150 remains in this intermediate position until the authorized key is introduced into channel 44 then turned. When the authorized key is turned, this causes the wheel 120 to rotate and the tip 154 then sinks between two teeth, thus immediately blocking the rotation of the wheel 120. Then, when the rehabilitation command is received, the power supply to the actuator is cut and the return spring automatically returns the retainer 150 to its passive position.
  • the wheel 160 is mechanically connected, without any degree of freedom, with a toothed wheel 166.
  • the toothed wheel 166 rotates on itself around the axis 106 when the wheel 160 turns.
  • the wheel 166 constitutes the output shaft 70 of the differential 80.
  • the wheel 166 is meshed with the rack of the bolt mechanism 10 to move it between its protruding and retracted states.
