Definitions

  • the present invention concerns an electronic lock cylinder suitable for replacing mechanical cylinders of known Yale type locks, and an electronic key for actuating such a cylinder.
  • the state of the art includes a solution (EP 1 707 712 A1 , "Cylinder lock assembly with mechanical and electronic mechanism”) that combines the classic mechanical code with an electronic code.
  • the unlocking code is stored in an electronic circuit on the key that is powered by the cylinder through mobile and sliding electrical contacts, which are not very reliable because they suffer from wear and from the influence of environmental factors.
  • the manufacturing cost of such key is higher than a simple passive key.
  • This solution also allows the key to be inserted just at one end of the cylinder due to the presence of the battery, the motor and the decoding circuit at the other end.
  • an activation switch comprises a sensor for exclusively detecting the absence or the presence of the key and controlling the power supply of the locking/unlocking circuit in on/off mode. This means that the higher is the absorption of electrical energy, the longer is the time the key stays inserted in the cylinder. This solution is therefore unsuitable for replacing a classic mechanical cylinder when a battery-power is used; on the other hand, this solution is more suitable for the use with electrified and motorised locks, also by virtue of the circular section of the key and its housing that do not allow manual actuation of the bolt.
  • a purpose of the present invention is to avoid the aforementioned drawbacks of the state of the art, and in particular to provide a cylinder for electronic key locks that can easily replace the lock cylinders for mechanical keys, for example so-called Yale locks, of locks that have already been installed.
  • Figures 1-7 relate to a lock and related electronic key according to a first embodiment of the invention.
  • a lock is meant of the type commonly indicated in the jargon as “Yale lock” or rotary drum lock.
  • This kind of lock generally comprises an outer housing, a rotary drum inside the drum and one or more mechanical locking/unlocking elements that, when the correct key is inserted in the drum, move transversally to the axis of the latter, allowing it to rotate.
  • Yale or cylinder locks can be divided into different varieties, including the pin tumbler lock, wafer tumbler lock, disc tumbler lock.
  • the lock cylinder 1 comprises a cylinder housing 3 and a driving pin 5A, 5B housed in the cylinder housing 3.
  • the cylinder housing 3 and the driving pins 5A, 5B are called, in the technical jargon, "fixed cylinder”/" cilindro fisso” and “sprocket”/ “rocchetto", respectively.
  • a key seat 7 is provided that is suitable for receiving a key 9, on which the reproduction of a predetermined unlocking combination is formed ( Figure 3 ).
  • a key opening 2 is formed so to act as a keyhole of the lock, and through which the key 9 can be introduced into the key seat 7 ( Figure 2 ).
  • the lock cylinder 1 is provided with a logic circuit which in turn comprises:
  • the logic unit 11 can consist of, or in any case comprise, a suitable programmable microprocessor.
  • the reading sensor preferably comprises:
  • Each emitter 170A can be or comprise for example an LED
  • each receiver 170B can be or comprise for example a photo cell, a photo diode, a phototransistor or CCD or CMOS photodetectors.
  • one or more of the following elements is housed in the cylinder housing and is integral with it, and is also arranged outside of the driving pin, not mounted on it but integral with the outer housing 3: the logic unit 11, the reading sensor 170A, 170B, the one or more emitters 170A, the one or more receivers 170B.
  • the reading sensor comprises a plurality of emitters 170A and a plurality of receivers 170B, and both the emitters 170A and the receivers 170B are arranged on at least one row that extends transversally, and more preferably perpendicular, to the insertion direction D1 of the key 9 in the key seat 7 or in any case in the keyhole 2 ( Figures 2 , 3 ), allowing the emitters 170A and the receivers 170B to be made less bulky.
  • the emitters 170A are arranged in front of the receivers 170B so as to be able to irradiate them directly with a rectilinear trajectory, allowing the circuitry of the reading sensor to be sensibly simplified, increasing its reliability and also allowing the construction of the key 9 to be simplified.
  • the one or more emitters 170A, the one or more receivers 170B - or more generally the reading sensor - and the logic unit 11 are arranged to read the combination of the key 9 when the latter is in movement
  • the emitters 170A and the receivers 170B are preferably arranged close to the opening 2 that forms the keyhole of the lock, so as to be able to start reading as early as possible the combination of the key 9 as soon as it begins to be inserted in the keyhole 2. Moreover, even the arrangement of the emitters 170A and the receivers 170B close to the opening 2 allows the layout of the logic circuit to be optimised and made less bulky.
  • the one or more emitters 170A, the one or more receivers 170B and the logic unit 11 are arranged to read the combination of the key 9 with a so-called majority vote algorithm, i.e. the emitters 170A emit impulses of detection radiations with sufficiently high frequency so to allow the receivers 170B to carry out many readings, preferably at least three, and even more preferably at least ten, of each window 96 of the key 9 that passes in front of them when the key is being inserted in the keyhole 2.
  • the reading with majority vote algorithm reduces the probability of incorrect readings of the combination reproduced by the key, it can be implemented with few instructions of a software program residing inside the cylinder and it can involve very low energy consumption.
  • an electrical power supply 19 is housed, arranged for powering one or more of the logic unit 11, the one or more emitters 170A and the one or more receivers 170B; advantageously, the electrical power supply 19, which can for example be a battery or another storage cell of electrochemical energy, is fixed to the housing 3 or in any case it is integral with it, contributing to make the electronic circuit that implements the logic circuit of the cylinder 1 more compact, less bulky and simple.
  • the logic circuit is provided with an activation switch 15 arranged to activate the logic unit 11 when the key 9 is close to the lock cylinder or partially inserted in the key seat 7 or in the key opening 2, making the logic unit 11 pass from a first stand-by operating mode, i.e.
  • the logic unit 11 performs all the functions needed to control the motor while engaging or disengaging - or in general actuating - the driving pin 5A and/or 5B, the power consumption of the logic unit 11 can be very high but preferably for a very short time interval, for example not longer than 3 seconds.
  • the logic unit 11 performs the functions needed to switch from the stand-by operating mode to the fully operating mode and the power consumption of the logic unit 11 is preferably kept at a medium level, lower than power consumption at fully operational mode and for very short time periods, for example not longer than 3 seconds.
  • the activity of the logic unit 11 is reduced to the bare minimum for detecting the insertion of the key 9 in the lock cylinder 1; preferably in stand-by the clock frequency of the logic unit 11 is also reduced.
  • the power consumption of the logic unit 11 is preferably reduced to the minimum, for example to not more than 1% of the power consumption during wake-up or fully operational mode.
  • the power consumption of the logic unit 11 in stand-by can for example be equal to or less than 50 ⁇ W, or in any case not more than a few tens of ⁇ W.
  • the activation switch 15 is a normally-open type.
  • the switch 15 can comprise or consist of one or more reed contacts capable of opening or closing in the presence of a magnetic field or in any case of a variation of the magnetic field in which the contacts are immersed.
  • the reed contacts are open, so as not carrying current and reduce power consumption of the logic unit 11 in stand-by.
  • the logic circuit comprises two boards or plates for electronic circuits 21A, 21B arranged facing one another; the one or more emitters 170A are fixed on one of the two boards or plates, for example 21a, whereas the one or more receivers 170B are fixed on the other of the two boards or plates, for example 21B ( Figure 5 ): such an arrangement sensibly simplifies the practical embodiment of the logic circuit, for example making it much easier to face the emitters 170A and the receivers 170B opposite one another.
  • the contraposition of the plates 21A, 21B makes it possible to greatly simplify the paths and the connections of the tracks that supply the various components of the logic circuit or transmit the related signals, and in order to allow the interconnection of electrical power supply or signals between the two plates it may be sufficient to use dedicated pins or a suitable connector.
  • each pair of boards or plates for electrical circuit 21A, 21B is separated, in the direction perpendicular to the insertion and extraction direction of the key, by an empty space in which the electrical power supply 19 is housed ( Figure 5 ): this arrangement also greatly contributes to simplify the logic circuit, and in particular its power supply or signal tracks, as well as reducing the overall size of the circuit itself, allowing larger and higher capacity batteries 19 to be housed in the cylinder housing 3.
  • the electrical contacts that touch the power supply 19 supplying its energy to the rest of the logic circuit of the cylinder 1 are arranged one on a power supply plate 21A or 21B, the other contact on the other facing power supply plate, 21B or 21A respectively, further simplifying the circuit.
  • an opening 35 is formed on the cylinder housing 3 arranged on the front or rear face of the lock cylinder 1, so as to face onto the empty space between the two boards or plates for electrical circuits 21A, 21B, allowing access and allowing the storage cell 19 to be easily replaced, with a very basic and compact electro-mechanical construction.
  • a lock cylinder like that of Figure 5 provided with two driving pins 5A, 5B able to be actuated one by inserting a key for example from outside a home, and the other from inside.
  • the lock cylinder 1 comprises an actuating clutch arranged for:
  • the actuating clutch can comprise one or more sliding shafts 23A, 23B, each of which is arranged to engage and disengage reversibly with a corresponding driving pin 5A, 5B translating along its axis (arrow D2).
  • Each sliding shaft 23A, 23B can be permanently engaged with the bolt actuation tooth 25, so as to be able to actuate it.
  • the lock cylinder 1 is advantageously provided with one or more clutch motors 27A, 27B each of which is arranged to move a corresponding sliding shaft 23 under the control of the logic unit 11.
  • each clutch motor 27 can actuate the corresponding sliding shaft 23A, 23B through a speed reducer comprising the gear wheels 29A, 29B; 31A, 31B and the screw/nut screw mechanism 33A, 33B.
  • FIG. 6 shows an embodiment of a key 9 that is particularly advantageous and suitable for being used to actuate a lock cylinder 1 according to the invention.
  • the key 9 comprises a control head 90, a shank 92 narrower than the control head 90 and preferably a gripping end 94, wider than the shank and arranged to be gripped.
  • the control head 90 is preferably shaped substantially like a plate or parallelepiped, and more preferably like a more or less squashed parallelepiped.
  • On the control head 90 a plurality of windows 96 is preferably formed, some of which can be crossed by detection radiations - i.e. they are transparent to radiation -, whereas the material that surrounds them is more opaque to such radiations.
  • the transparent windows 96 are arranged so that the detection radiations emitted by one of the emitters 170A after having crossed a corresponding window 96 strike one of the receivers 170B.
  • the windows 96 are aligned according to a plurality of rows 90R and columns 90C.
  • the number of rows 90R and/or columns 90C is equal to or greater than three.
  • the number of rows 90R can be comprised between 4 and 5, and the number of columns 90C between 4 and 10.
  • Such numbers of rows and columns allow a key to compose a sufficiently large number of opening combinations; indeed, with three rows and three columns it is possible to compose more than 500 possible nominal opening combinations, with four rows and four columns it is possible to compose more than 65000 and with five rows and six columns it is possible to compose more than one billion, i.e. much more than the number of combinations (100,000) above which the standard EN 1303 classifies a lock at the maximum degree of safety.
  • the unlocking combination reproduced by the key 9 is obtained by ensuring that part of the windows 96 are also opaque to the detection radiations.
  • the number and position of the transparent windows 96 and of the opaque windows is preferably different in the various columns 90C, so as to greatly increase the number of possible combinations potentially able to be reproduced by the key 9.
  • the transparent windows 96 are made from a material substantially opaque to visible light but transparent to non visible detection radiation, i.e. ultraviolet or infrared, emitted by the emitters 170A.
  • each window 96 fills the corresponding cavity formed in the remaining part of the head 90 flush with the surface of the head itself.
  • an activation element 98 arranged to activate the activation switch 15 when the control head 90 starts to enter into the keyhole of the lock 2 or into the key seat 7.
  • the activation element 98 can be or can comprise for example a permanent magnet, an electromagnet or another generator of magnetic field or even just a piece of electrically and/or magnetically conductive material, depending on the type of activation switch 15 used.
  • the choice of a permanent magnet has the advantage of not requiring a key 9 with batteries or other sources of internal energy and allows a switch to be used that does not have mechanical contacts with the key (contactless), providing advantages in terms of reliability of activation and much longer lifetime, thanks to the lower exposure to wear and to foreign agents; in this case preferably the activation switch 15 comprises or consists of reed contacts that are open in the absence of magnetic fields.
  • the activation switch 15 besides reed contacts can comprise a permanent magnet that, when the key 9 is not inserted in the lock cylinder 1, keeps the reed contacts open - which in this case would be normally-closed type - whereas the activation element 98 preferably comprises a material capable of deviating the flux lines of the field of the permanent magnet enough to open the reed contacts when the key 9 is inserted into the cylinder 1. Mounting the permanent magnet on board of the lock instead of the key allows the costs of the system to be reduced, whilst still allowing a switch without mechanical contacts with the key (contactless) to be made.
  • the two smaller sides of the cross sections of the control head 90 are substantially shaped like an arrowhead or peaked ( Figure 6 ), just as the smaller sides of the keyhole 2 of the cylinder correspondingly have such a shape ( Figures 2 , 7 ), so as to ensure the correct orientation of the key in the lock without occupying the useful surfaces of the key reserved for the encoding windows.
  • the cross sections of the control head 90 of the key advantageously have a shape without axial, rotary, star-like or circular symmetries, so as to ensure that the key is inserted in the keyhole with a single and very precise orientation with respect to the insertion direction.
  • the key 9 is purely passive and not powered by any internal electrical or chemical energy source.
  • a lock cylinder according to the invention can also be provided with two keyholes 2 and with some or all of the following items: two or more emitters 170A, two or more receivers 170B, two clutch motors 27A, 27B, two groups of gear wheels and of screws 29A, 31A, 33A; 29B, 31B, 33B.
  • both the emitters 170A, the receivers 170B and the clutch motors 27A, 27B are controlled by a single logic unit 11 and are powered by a single storage cell 19.
  • the logic circuit advantageously comprises a fifth board or plate for electronic circuits or flexible plate or flat cable 21C that mechanically fixes and electrically connects the two boards 21A and/or the two boards 21B together, according to the insertion and extraction direction of the key ( Figure 5 ).
  • a fifth board or plate for electronic circuits or flexible plate or flat cable 21C that mechanically fixes and electrically connects the two boards 21A and/or the two boards 21B together, according to the insertion and extraction direction of the key ( Figure 5 ).
  • one or more electric conductors that electrically connect together the electrical and electronic components arranged on the two boards or plates 21A or 21B are arranged on the fifth board or plate, for example connecting the single storage cell 19 and/or the single logic unit 11 to both of the emitters 170A, both of the receivers 170B and/or both of the clutch motors 27A, 27B.
  • the fifth board 21C is already fixed to and integral with the two boards 21A and/or the two boards 21B before being inserted in the rest of the lock cylinder
  • the permanent magnet of the activation element 98 closes the contacts of the reed that acts as activation switch 15; the closure of the contacts is detected by the logic unit 11, which passes from the stand-by state to the wake-up state, and from this to the fully operational state.
  • the logic unit 11 then activates the emitters 170A and the receivers 170B, starting to supply them with power, which start to progressively read the unlocking combination reproduced by the windows 96. More specifically, the emitters 170A and the receivers 170B detect the sequence of ones and zeros reproduced by the various columns 90C of the key as the columns slide in front of the emitters 170A and the receivers 170B, i.e.
  • the logic unit 11 detects that the unlocking combination read by the receivers 170B is equal to one of the opening combinations stored in the unit 11 itself, it commands the unlocking of the cylinder 1 by actuating the clutch motor 27, which through the gear wheels 29A, 31A and the screw mechanism 23A makes the sliding shaft 23A translate, engaging it with the driving pin 5A and keeping it simultaneously engaged with the bolt actuation tooth 25. Therefore, by rotating the driving pin 5A by turning the key 9 inserted in the key seat 7 it is now possible to rotate - or in any case actuate - the tooth 25 and open or close the bolt of the lock 102.
  • the logic unit 11 is programmed or in any case arranged to disengage again the driving pin 5A from the sliding shaft 23A, once again preventing the actuation of the tooth 25 rotating the driving pin 5A.
  • the choice to activate the lock cylinder 1 by making it pass to the higher consumption mode only when the key 9 is inserted greatly reduces the energy consumption of the cylinder, since the latter stays in the first minimum energy consumption operating mode, i.e. stand-by, on average for at least 90% or in any case for the majority of its operating life.
  • the particular choice of reed contacts to make the activation switch 15 allows the energy consumption of the lock cylinder 1 to be kept quite low in the stand-by state, as well as allowing a simple, cost-effective switch to be made without mechanical contact with the key 9.
  • the different solutions that allow the electrical/electronic circuit housed in the lock cylinder 1 to be made more compact and simplified also contribute to reduce its energy consumption in general.
  • the driving pin 5 Since the driving pin 5 is turned manually by the end user through the key 9, the movement of the bolt 102 and the opening of the lock do not involve absorption of energy from the storage cell 19 and make using the new lock totally equivalent - i.e. manual - to that of old mechanical locks; this does not prevent making cylinders for motorised locks of the latest generation according to the invention. Since they are only used to move the sliding shafts 23A, 23B, the clutch motors 27A, 27B absorb very little energy and can have for example approximately maximum powers of about 40 mW or even less.
  • the shape substantially like a plate, like a parallelepiped - or in any case different from that of a rotation solid - of the control head 90, in particular like a squashed parallelepiped, is particularly effective and handy for manually rotating the driving pin 5, as well as reducing the wear of the head 90 itself and of the inside of the lock.
  • the narrower shank 92 of the control head 90 advantageously allows a narrower keyhole 2 to be adopted that better protects the components inside the cylinder 1.
  • the reading sensor 170A, 170B is at the shank 92, all of the circuits and the electrical components of the lock can be placed outside of the driving pin 5A, 5B and stay fixed with respect to the cylinder housing 3 while the pin 5A or 5B rotates; this allows the electromechanical implementation and circuitry of the cylinder 1 to be made substantially simpler, avoiding for example sliding electrical contacts or transmission of electromagnetic signals.
  • Figure 7 provides an indicative example of the external dimensions of the cross sections of a common European profile cylinder, in which the electrical-electronic circuits and the mechanisms according to the invention can be housed: the height H1 can be about 33 mm, the width L1 about 17 mm and the width L2 about 10 mm.
  • the lock cylinders according to the invention can replace, very easily and at low cost, the mechanical cylinders - for example with pistons - currently mounted on the overwhelming majority of external doors of homes, gardens, enclosures, wine cellars, garages, offices, workplaces and places with limited access in general.
  • a cylinder for locks 1 is particularly suitable for being used with different keys that can open and close it with different opening combinations, and allows the modification of the opening combination - or combinations - to be managed with great flexibility and ease through a simple reprogramming of the logic unit 11, the replacement of keys and the management of various situations like for example losing a key, changing tenants, enabling opening with one new key and only one, opening a lock with different keys and opening some locks, but not others, with a single key.
  • the activation switch 15 can for example comprise:
  • the reading sensor can comprise a microcircuit reader, said microcircuits being able to be housed on the key 9.
  • a lock cylinder according to the invention can also be powered from the outside, for example if mounted on security doors with external power supply also - but not only - in order to motorise opening, still ensuring the operation of the door when there is no current.
  • a lock cylinder according to the invention can also be arranged to be opened with a key on just one side of a door, and in this case a single emitter 170A, a single receiver 170B, a single driving pin 5A, a single sliding shaft 23A and a single clutch motor 27A can be provided.
  • a key 9 can also be provided with several activation elements 98, arranged so to be read in sequence while the key is inserted or extracted from the keyhole 2 and allow the logic unit to recognise whether the key is inserted or extracted from the lock cylinder; for this purpose, an activation element 98 can be placed on the free end of the key and a second activation element 98 closer to the end to be gripped.
  • the control head 90 can more generally have a different shape from that of a solid of revolution, and for example have a radiated symmetry or completely asymmetrical shape with respect to the rotation axis of the key 9.
