Description

[0001] The present invention relates to an electronic device for opening and / or closing a door, or the like, comprising an electric lock, as well as a method of installing such an electric lock on a door or the like.

[0002] The field of the invention is that of electric locks: this type of lock comprises an electric actuator for changing the state of the lock, namely from a closed state to an open state, this actuator being controlled by the electronics of a control unit connected in turn to means for receiving a signal from a transmitter.

[0003] The invention is more particularly concerned with electronic devices in which the opening or closing of the door by the electric lock is controlled from a light signal in the visible range, the light pulses of which define an opening and / or closing code.

[0004] This opening / closing code is emitted by a portable transmitter having means for emitting said light signal. The portable transmitter may be a smartphone onto which suitable software is downloaded. The means for emitting the light signal may be the phone's flash.

[0005] Such a state of the art is for example disclosed by the device of document WO2016 / 124544 A1 which comprises: a lock cylinder which is coupled to an electric actuator marked 13 such as a motor for changing the state of the lock, reception means marked 16, comprising a photodiode marked 20, adapted to detect the pulses of the light signal, a control unit marked 17, connected to said reception means and connected to the actuator 13, comprising electronics configured to decode the light pulses of the signal detected by said reception means and to determine a command of the actuator 13 for the change of state of the electric lock.

[0006] Such an electric lock is advantageous in that it allows the user's smartphone to be used as a control device, after downloading the dedicated application. The use of a control signal in the form of light pulses further provides a high level of security, thanks to the use of the phone's flash. The light flux of the flash being substantially directional, it is thus more difficult to hack compared to WIFI or Bluetooth ®< signals, which radiate, can be easily listened to: this reduces the risk of hacking.

[0007] On the contrary, and according to the inventors' findings, the use of a light flux as a control signal requires the reception means 16, and in particular the photodiode, to be provided on the outside of the door, namely on the same side from which the light signal is emitted, and as illustrated in figure 1 of document WO2016 / 124544 A1, or to provide for the integration of this photodiode in a housing, received in the door, this housing making it possible to receive the smartphone from an access opening on the outside of the door. This housing then has an opening for the passage of the light signal to the detector photodiode, referenced 220, and as illustrated according to the embodiment of the figures 5 , And 6 from document WO2016 / 124544 A1.

[0008] In both cases, whether it is the method of realization of the figure 1 , or that of the figures 5 And 6 , the means of receiving the light signal require for their integration a specific and dedicated housing in the door, that is to say a housing separate from the housings already present in the door for the integration of the handle and the lock cylinder in particular.

[0009] The method of realization of the figure 1 with easily accessible photodiode on the outside of the door can still be easily damaged by vandalism, rendering the electric lock inoperable.

[0010] The aim of the present invention is to overcome the aforementioned drawbacks by proposing an electronic device configured to open / close a door or the like, from a light signal defining an opening and / or closing code emitted by a portable transmitter having means for emitting said light signal and whose electric lock is of simplified installation compared to the aforementioned state of the art, and while limiting the aforementioned risks of vandalism.

[0011] Advantageously, and as will be understandable later: the installation of the electronic device according to the invention will not require in terms of installation steps, no additional step compared to those necessary for the assembly of a conventional lock cylinder known by a person skilled in the art as a European cylinder, namely that the fixing of such a European type cylinder, requires just the insertion of the lock cylinder in a through housing of the door of a shape adapted for a European profile cylinder, then the installation of a fixing screw from the edge of the door, this screw engaging with a thread of the stator of the lock cylinder to ensure the locking in position of the lock cylinder in its housing, the receiving diode of the electronic lock and used to detect the pulses of the light signal will be inaccessible, and thus protected from malicious acts.

[0012] Other aims and advantages of the present invention will appear during the description which follows, which is given for information purposes only and is not intended to limit it.

[0013] The invention also relates first of all to an electronic device configured to open / close a door or the like, from a light signal defining an opening and / or closing code emitted by a portable transmitter having means for emitting said light signal, said electronic device having an electric lock comprising: a lock cylinder with a stator and a rotor, as well as an electric actuator configured to change the state of the electric lock, from an open state to a closed state, or vice versa, signal receiving means configured to detect light pulses in the visible range comprising a receiving diode, a control unit connected to the receiving diode and connected to the electric actuator, configured to decode the light pulses detected by said receiving means and determine a command of the electric actuator for changing the state of the lock.

Said channel passing through the stator of the lock cylinder from the longitudinal end called the outer end to the other longitudinal end, called the inner end; which the housing internally receives the electric actuator; the housing receives a source of electrical energy (such as a battery or batteries) for the electrical supply of the control unit (5) and the electric actuator; the electric actuator comprises an electric motor, with an axis of rotation substantially perpendicular to the axis of rotation of the rotor of the lock cylinder, as well as a gear forming an angle transmission, comprising a first bevel gear secured to the rotor, and a second bevel gear secured to the output of the electric motor;the electric lock comprises a manual control comprising a gripping part, intended to be actuated from the inside of the door, and a shaft secured to the rotor, extending from the rotor to the outside of the stator, from the inside end of the stator, the manual control being configured so as to allow the state of the lock to be changed by a manual rotation action on the gripping part;the rotor actuated by said electric actuator is called the first rotor, the lock cylinder comprises a second rotor, provided inside the stator, independent of the first rotor, said second rotor having a recess forming a key path for receiving a key, the second rotor being configured so as to allow the change of the state of the lock by rotation of the key inserted in the key path of the second rotor from the outer end of the stator, a clutch mechanism being configured to ensure the clutch of the second rotor to the bit only when the key is inserted in the key path of the second rotor; the second rotor and stator assembly forms a pin tumbler lock;the receiving diode is configured to detect the light pulses and to emit a visual light signal visible from the outer end of the stator, and in which following the detection of a light signal defining an opening and / or closing code, and generation by the control unit of a closing or closing command, the control unit is configured to control the diode in order to emit a visual signal testifying to the success of the opening or closing operation.;

[0018] The invention also relates to a laying method comprising the following steps: providing a self-supporting assembly of an electric lock of an electronic device according to the invention inserting the lock cylinder of the self-supporting assembly into a door housing intended for receiving a lock cylinder, from the side of the door opposite that from which the light signal is intended to be emitted to control the opening or closing of the electric lock, locking the self-supporting assembly by inserting the fixing screw from the edge of the door and screwing the fixing screw into the threaded bore of the stator of the lock cylinder.

[0019] The invention will be better understood by reading the following description accompanied by the appended figures, including: There figure 1 is a perspective view of an electric lock of an electronic device according to the invention, the lock cylinder, the signal reception means and the control unit advantageously form a self-supporting assembly, and according to an embodiment for which the lock cylinder, of European profile, may be controlled not only by the actuator, but also by a flat key, The figure 2 is a sectional view of the electric lock of the figure 1 , along a vertical plane passing through the lock cylinder, illustrating more particularly the positioning of the diode set back from said outer end of the stator of the lock cylinder, and the presence of a channel allowing the transmission of the light signal along the stator, to the diode received inside a projecting housing secured to the inner end of the stator of the lock cylinder. figure 3 is an exploded view of the lock cylinder of the device of the figure 1 , more particularly illustrating the stator, the first motorized rotor and a second rotor with a cavity for a keyway, the key bit which is actuable by the first rotor or the second rotor, the clutch / disclutch mechanism for coupling the second rotor to the key bit only upon insertion of a key; and the active pins and passive pins of the pin tumbler lock formed by the stator / second rotor assembly, as well as an optical fiber intended to extend into the channel of the stator. figure 4 is an exploded view of the single-rotor lock cylinder that can replace the one in the figure 3 , more particularly illustrating the stator, the motorized rotor and the bit which is actuated by the rotor, and an optical fiber intended to extend in the channel of the stator, said lock cylinder being devoid of a key mechanism. figure 5 is a schematic view illustrating a second embodiment for which the channel allowing the transmission of the light signal is formed between a plate or the like at the base of the stator and a housing for a European profile lock cylinder. figures 6 et 7 illustrate the two assembly steps for fitting the self-supporting assembly to a door, namely inserting the lock cylinder of the self-supporting assembly into a door housing from the side of the door opposite that from which the light signal is intended to be emitted to control the opening or closing of the electric lock, then locking the self-supporting assembly by inserting the fixing screw from the edge of the door and screwing the fixing screw into the threaded bore of the stator of the lock cylinder.

[0020] The invention also relates to an electronic device 1 configured to open / close a door P or similar, from a light signal defining an opening and / or closing code emitted by a portable transmitter having means for emitting said light signal.

[0021] For this purpose, the electronic device has an electric lock comprising: a lock cylinder 2 with a stator 20 and a rotor 21, as well as an electric actuator 3 configured to change the state of the electric lock, from an open state to a closed state, or vice versa, signal reception means configured to detect light pulses in the visible range comprising a receiving diode 4, a control unit 5 connected to the receiving diode 4 and connected to the electric actuator 4, configured to decode the light pulses detected by said reception means and determine a command of the electric actuator 3 for changing the state of the lock.

[0022] Notably and according to the invention, the lock cylinder 2, the signal receiving means and the control unit 5 form a self-supporting assembly 6, the device being configured so as to allow the self-supporting assembly 6 to be mounted on the door by inserting the lock cylinder 2 into a door housing Lg P intended for a European profile lock cylinder (see figure 6 ), then installation of a fixing screw 7 cooperating with a tapped bore 201 of the stator 20 from the edge of the door (see figure 7 ).

[0023] The installation of the electronic device 1 according to the invention is therefore extremely simple and does not require, in terms of steps, any additional steps to those required for the installation of a conventional lock cylinder, of European profile.

[0024] The lock cylinder 2 comprises said stator 20 and said rotor 21 rotated by the electric actuator 3, as well as a bit 22 rotated by the rotor 21, intended for controlling a locking bolt. The stator 20 has two longitudinal ends, with a so-called outer end Ee which, when the lock cylinder 20 is housed in said housing Lg of the door, is intended to be positioned on the side of the door from which the light signal is emitted to control the opening or closing of the electric lock. This is then referred to as the outer side of the door. The stator 20 also comprises an inner end Ei of the stator 20 which is intended to be positioned on the opposite side of the door P from that from which the light signal is emitted to control the opening or closing of the electric lock: this is then referred to as the inner side of the door.

[0025] Notably, said receiving diode 4 belonging to said receiving means is advantageously positioned at a distance from the outer end Ee of the stator of the lock cylinder 2 towards the inner end Ei, said receiving diode 4 inaccessible at least when said self-supporting assembly is mounted on the door, in particular inside the self-supporting assembly. The resistance of the electronic device against the risks of malicious acts is improved in that it is not possible to easily damage this diode from the outer side of the door.

[0026] According to a first possibility of the invention illustrated by way of non-limiting example in the figure 2 , the stator 20 comprises a channel 204 of closed section opening at the outer end Ee of the stator 20, said channel 204 being configured to allow the transmission of the light signal emitted from the outer side of the door to said receiving diode 4, arranged internally and inaccessible.

[0027] Alternatively, and according to a second possibility illustrated by way of non-limiting example in the figure 5 , the stator 20 comprises an open channel or a flat 24 configured so as to form a closed section channel 205 only once the lock cylinder 2 is mounted in a housing Lg of the door P for a European profile lock cylinder. This channel thus formed is configured to allow the transmission of the light signal emitted from the external side of the door to said receiving diode 4, arranged internally and inaccessible.

[0028] A cylinder 2 of European profile comprises a stator with a circular part 2a coaxial with the rotor(s) of the cylinder, and an elongated part 2b extending radially in growth from the circular part, and terminated at its lower part by an arcuate convex profile 2c.

[0029] As shown in the figure 5 , the base of the stator 20 may have a flat, in particular at the base of the stator, over all or part of the length of the stator, and so that a closed section channel 205 is created between an arcuate profile at the base of the housing for the European profile cylinder and the flat: on the figure 5 this dish removes the aforementioned arched profile 2c, and with a view to creating channel 205.

[0030] According to the first embodiment possibility, it is noted that the closed section channel can be produced by a longitudinal bore, in particular over the entire length of the stator 2, produced on the section of the aforementioned arcuate profile stator 2c. It is also noted that this channel can be located below the threaded bore 201 configured for fixing the lock cylinder 2, this threaded bore 201 being, in a conventional manner, substantially orthogonal to the axis of the stator and to the radial direction of the elongated part 2b, made by removing material in the elongated part 2b.

[0031] According to one embodiment, an optical fiber 8 can be configured to ensure the guidance of the light signal from the outer end Ee of the stator 20 and to the diode 4 internal to said self-supporting assembly 6 arranged internal to the channel 204 of the stator according to the first possibility, or in the channel 205 formed between the housing for a European profile cylinder and the stator 2, according to the second possibility.

[0032] According to one embodiment, said self-supporting assembly 6 may comprise a housing 9 secured to the stator 20 of the lock cylinder 2 projecting from the inner end Ei of the stator 20. This housing 9 receives all or part of the following elements: the control unit 5, the receiving diode 4, the electric actuator 3, an electrical energy source such as a battery or batteries for the power supply.

[0033] The housing 9 can be fixed to the inner end Ei of the cylinder stator by means of screws 90 engaging with threaded bores of the stator 20. The threaded bores are for example provided on the elongated part 2b, and as illustrated in figure 2 . For example, the housing comprises a fixing plate 91 and a cover 92 (removable) forming between them an inter-space for receiving the aforementioned elements. The plate 91 is for example supported on the flat surface at the inner end Ei of the stator, the plate 91 being fixed to the stator 20 by the fixing screws 90.

[0034] The cover is a hollow element which can be fixed to the plate 91, by screws 93, passing through holes in the plate 91. Of course, other methods of fixing can be envisaged between the plate and the housing, such as fixing by clips.

[0035] In the case where the housing internally receives the receiving diode 4 of the receiving means, and according to the first possibility, said channel 204 passes through the stator 20 of the lock cylinder from the longitudinal end called the outer end Ee to the other longitudinal end, called the inner end Ei. In the case where the housing internally receives the receiving diode 4 of the receiving means, and according to the second possibility, the flat 24 extends over the entire length of the stator 20.

[0036] The electric actuator 3 may comprise an electric motor 30, and a gear connecting the output of the electric motor with the rotor 21. This electric motor 30 causes the rotation of the rotor 21, and of the associated blade 22 when controlled in a direction of rotation when opening, or in a direction of rotation when closing.

[0037] As illustrated as an example in the figure 2 , this motor 3 can have an axis of rotation substantially perpendicular to the axis of rotation of the rotor 21 of the lock cylinder 2. The gear then forms an angle transmission, and comprises a first bevel gear 31 secured to the rotor 21, and a second bevel gear 32 secured to the output of the electric motor 30.

[0038] The electric lock may also comprise a manual control comprising a gripping part 11, intended to be actuated from the inside of the door P, and a shaft 12 secured to the rotor 21, extending from the rotor 21 to the outside of the stator, from the inside end of the stator 20. This manual control is configured so as to allow the state of the lock to be changed by a manual rotation action on the gripping part 11.

[0039] To the figure 2 , we note that said shaft 12 is coaxial with the rotor 21, and passes through the housing 9, on either side, emerging outside by its terminal end. The gripping part 11 is fixed to the terminal end of the shaft 12, for example via a clamping screw 13.

[0040] According to an embodiment illustrated as an example of the figures 1 à 3 , the lock cylinder 2 comprises a second rotor allowing actuation with a key. Thus, the rotor 21 actuated by said electric actuator 3 being said first rotor, the lock cylinder 2 comprises a second rotor 23, provided inside the stator 20. This second rotor 23 has a longitudinal recess forming a key path and is configured so as to allow the state of the lock to be changed by rotating the key inserted in the second rotor 23, from the outer end of the stator. The second rotor 23 and stator 20 assembly can thus form a pin tumbler lock.

[0041] Such an embodiment is illustrated by way of non-limiting example in FIG. figure 3 : the stator 20 comprises, from the outer end Ee, a first section of length 26 with a circular part comprising a bore intended to receive the second rotor 23, followed by a second section of length 27 with a circular part comprising a bore intended to receive the first rotor 21. A notch 28, intermediate between the first section of length 26 and the second section of length 27, receives the bit 22. This bit 22 comprises a driver 220 intended to engage with the actuating mechanism a bolt of the door, as well as a ring 221, mounted coaxially with the rotors 21, 23.

[0042] A clutch mechanism 25 is configured to provide clutch engagement of the second rotor 23 to the bit 22 only when the key is inserted into the key path of the second rotor 23.

[0043] The clutch mechanism may comprise a key device received through the ring 221 of the bit 22 and which comprises two shaft parts 25a and 25b, secured to each other by a pivot with an axis coaxial with the shafts 25a and 25b. The shaft part 25a comprises a key 29 securing the rotation of the part 25a to the second rotor 23 and the shaft part 25b comprises a key (not visible) securing the shaft part 25b to the first rotor 21.

[0044] This key device with parts 25a, 25b is mounted to slide along a limited stroke through the ring 221 of the bit, constrained by a spring in the direction of the second rotor 23 in the absence of a key.

[0045] In this position (key absent), only the key of part 25b engages with a keyway 33 of the bit 22, thus linking the rotation of the first rotor 21 to that of the bit 22: in particular and as illustrated in figure 2 , the part 25a is released from the keyway of the bit 22, thus disengaging the rotation of the second rotor 23 and the rotation of the bit 22: it is thus possible to drive the first rotor 21 and the bit 22 in rotation, without driving the second rotor 23 in rotation.

[0046] When a key is inserted into the key path of the second rotor, the end of the key comes into contact with the key device 25a, 25b driving the latter a limited stroke towards the bit 22, against the return force of the spring. This movement causes the second rotor 23 to engage with the bit 22 by engagement of the key 29 in the key groove 33 of the bit 22: the rotation of the key thus makes it possible to drive the rotation of the second rotor 23 and of the bit 22. Preferably, and in this position (key inserted) the first rotor 21 always remains coupled to the bit 22 (and to the second rotor 23): such an arrangement allows the electronics to detect an opening of the mechanism by key. For this purpose, an angular encoder makes it possible to follow the rotation of the first rotor. According to this embodiment, the stator 20, second rotor 23 assembly can form a pin lock. As illustrated in figure 3 , the second rotor 23 thus has radial bores for active pins 14, and the part 2b of the stator 20 has corresponding bores for passive pins 15, springs 16 pushing the pins 14, 15, bearing on plugs 17. In a known manner, the profile of the key makes it possible to ensure that the bearing plane between the active pins 14 and the passive pins 15 coincides with the second rotor 23 / stator interface, thus releasing the rotation of the second rotor 23.

[0047] According to another embodiment illustrated in the figure 4 , the lock cylinder 2 comprises a single rotor, marked 21 which can be moved by the electric actuator 3 by an electric command from the control unit 5, or from the inside thanks to the manual control which comprises the shaft 12 and the gripping part 11. On the other hand and according to this embodiment, this lock cylinder is devoid of a second rotor operating with a key. Thus and as illustrated in the figure 4 , the first section of length 26 of the stator 20 can be solid, only the second section of length 27 having a bore for the rotor 21.

[0048] Also notably, the diode 4 used may be a photodiode, used only in reception to detect the pulses. Advantageously, the receiving diode 4 may also be configured not only to detect the light pulses, but also to emit a visual light signal visible from the outer end of the stator 20. Following the detection of a light signal defining an opening and / or closing code, and generation by the control unit 5 of a closing or opening command, the control unit can control the diode in order to emit a visual signal testifying to the success of the opening or closing operation, for example in green color.

[0049] Conversely, if the light signal code is not recognized, the control unit can control the diode to emit a visual signal indicating the failure of the operation, for example in red.

[0050] The invention also relates to a laying method comprising the following steps: providing a self-supporting assembly 6 of an electric lock of an electronic device according to the invention, inserting the lock cylinder 2 of the self-supporting assembly 6 into a door housing Lg P) intended for receiving a lock cylinder, from the side of the door opposite that from which the light signal is intended to be emitted to control the opening or closing of the electric lock, locking the self-supporting assembly 6 by inserting the fixing screw from the edge of the door and screwing the fixing screw into the threaded bore 201 of the stator 20 of the lock cylinder 2.
