Description
- The present invention relates to an electronic device for driving a lock and an electronic lock comprising said device.
- Therefore, the present invention finds particular application in the field of security, and in particular in products for public or private building security.
- Over the last years, the research in the field of the locks is mainly directed along two distinct currents, namely the realization of more and more performing products from the point of view of the anti-break-in security and, contextually, the realization of more and more technological and user-friendly products.
- In this respect, electric and electronic locks are well known, in which the cylinder rotation is imparted by drives or suitably controlled electric motors.
- To allow the movement of the cylinder reducing the overall dimensions, in the prior art devices for driving the lock are known in which the axis of rotation of the electric motor is perpendicular to that of the cylinder and coupled to it by means of specific transmissions of the bevel gears type, or the like.
- Disadvantageously, this kind of coupling forces the manufacturer to a predetermined positioning of the motor and limits also the freedom in its dimensioning.
- In fact, this kind of direct coupling of such type requires the motor to be placed perpendicularly to the axis of the cylinder, which makes the motor diameter a very limiting parameter.
- Moreover, the direct coupling between the motor and the shaft or tang of the cylinder makes the balance between the need to have a performing motor and that to impact in a limited way on the possibility of manual operation by the user very hard.
- Furthermore, in the known solutions the electric motor is connected, sometimes in a reversible way, through specific "universal" supports, to a pre-existing cylinder, and has a number of wirings, which are integrated in the frame together with a control and driving interface.
- Disadvantageously, such solutions entail a considerable investment for the user, or for the manufacturer, who must change the frame structure to integrate all the electronics of the driving device.
- Other prior art solution are known from
documents EP 2 365 475 A1 ,EP 1 296 008 A1WO2004/009938 A1 ,DE 92 07 789 U1 orUS 2001/0027669 A1 . - In particular the
document EP 2 365 475 A1 discloses an electronic device for driving a cylinder lock. The device comprises a support for connection with the cylinder lock of an existing lock. The support has at least one through opening for accommodating a projecting portion of said cylinder lock. The device further comprises a gear motor provided with an actuator and a transmission configured to rotate the shaft or tang of said cylinder lock and allow the opening or closing of the lock, wherein the actuator is defined by an electric motor having an axis of rotation parallel and offset with respect to a central axis of said opening so as to be parallel to the cylinder lock. - Object of the present invention is therefore to provide an electronic device for driving a lock and an electronic lock comprising said device which overcome the aforementioned drawbacks of the prior art.
- In particular, object of the present invention is to provide an electronic device for driving a lock easily applicable to pre-existing locks and having limited overall dimensions.
- In addition, it is an object of the present invention to provide an electronic device for driving a lock, which does not impact, on the frame structure. Furthermore, object of the present invention is to provide a user-friendly, highly performing and interactive system for driving a lock.
- Said objects are achieved by an electronic device for driving a lock according to
claim 1 and by an electronic lock according toclaim 12. - More precisely, the intended objects are achieved by an electronic device for driving a lock comprising a support for connection with the cylinder of an existing lock having at least one through opening for receiving a projecting portion of said cylinder and fastening means to block the support with respect to said projecting portion, a gear motor provided with an actuator, and a transmission configured to rotate said cylinder and allow the opening or closing of the lock.
- According to the present invention, the actuator is defined by an electric motor having an axis of rotation parallel and offset with respect to a central axis of said through opening of the support so as to be parallel to the cylinder.
- Advantageously, in this way, the motor diameter is no longer a constraint for the producer, who has the possibility to select the most performing as well as the most powerful motor, without increasing the overall dimensions of the device.
- According to the invention, the transmission comprises at least a first and a second toothed wheel rotatably connected to each other, wherein the first toothed wheel is rigidly connected to the motor and the second toothed wheel has a coupling portion with a shaft or tang of the cylinder.
- Note that, in order to increase the multiplication or reduction effect, depending on the motor type, the transmission comprises a cascade of gears extending between said first and said second gear.
- To facilitate the positioning and the operation of the device on pre-existing locks, minimizing the overall dimensions, the coupling portion is defined by an opening, which can be coupled with the projecting portion of said shaft or tang of the cylinder and shaped so as to prevent a relative rotation (preferably substantially in a "D"-shape).
- In particular, a driving system may be provided, in such system is provided the presence of a driving device as described above further comprising a control board associated with said actuator, and provided with a communication module configured to put the control board in communication with a remote device.
- More precisely, the system also comprises at least one remote server connected to said control board via said communication module and a remote device provided with a programming interface connectable to said communication module of the device via said server, and configured to exchange data with said device in order to display the lock condition and/or allow an operator to set one or more operating parameters of the device.
- Advantageously, in this way, the user has the possibility to remotely drive and change the status and the response of the device, both by programming the opening/closing condition and enabling or disabling the users.
- These and other advantages will become more apparent from the following exemplary, and therefore non-limiting description of a preferred, and therefore not exclusive embodiment of an electronic device for driving a lock as shown in the following drawing tables, in which:
-

part 104a of thecylinder 104 has a fixed portion, which can be anchored to the frame and a rotatable portion crossed by a passage 105 for inserting a key. - The second half-

shaft 106 has a free end, distal from the first half-part 104a, shaped to couple with arotatable knob 103 suitable for allowing a quick opening/closing of the lock from the inside environment. - In use, in fact, the first half-
part 104a is faced from an outer side of the frame, while the first half-part 104b is faced from an inner side of the frame. - In this regard, the
shaft 106 or tang has at least one flattened portion of rotational coupling with theknob 103. - Note that the
cylinder 104 comprises at least one portion (fixed) projecting from the frame, or from a face of the frame, connected in series with theshaft 106 or tang. - The projecting portion is thus part of the second half-
part 104b. - The
electronic device 1 for driving thelock 100 is coupled, in use, to thecylinder 104 and in particular to the above projecting portion. - According to the invention, the
electronic device 1 comprises asupport 2 for connection with thecylinder 104 of thelock 100. -
Such support 2 has at least one through opening 3 for receiving the aforementioned projecting portion of thecylinder 104 and fastening means 4 to block thesupport 2 with respect to the projecting portion. - More precisely, the
opening 2 is shaped so as to fit on the projecting portion, and the fastening means 4 are configured to block thesupport 2 on the projecting portion. - Therefore, the
opening 3 extends crossing thesupport 2 along a central axis "B" which, in use, is parallel (or corresponding) to the extension axis of thecylinder 104. - In the preferred embodiment, the
support 2 is defined by aplate 5 provided with ahole 5a substantially complementarity shaped to the projecting portion of a commonEuropean cylinder lock 100 and defining said opening 3. - The fastening means 3 are preferably of the screw type in order to allow an accurate tightening of the
support 2 on the projecting portion, which is also suitable for cylinders with slightly variable dimensions. - In a first embodiment, the fastening means 4 comprise pressure elements translatable by means of a screw towards and away from the projecting portion (or from a centre of the opening 3) as a vice.
- Alternatively, such fastening means 4 may be defined by the two sides of the opening 3 elastically movable towards and away from each other by means of said screw.
- The
support 2 is also connected to agear motor 6 provided with an actuator 7 and atransmission 8. -
Such gear motor 6 is configured to rotate thecylinder 104 and allow the opening or closing of thelock 100. - According to the invention, the actuator 7 is defined by an
electric motor 7a having an axis of rotation "B" parallel and offset with respect to the central axis of said opening 3 so as to be parallel in use to thecylinder 104. - Note that the
motor 7a is not aligned to the cylinder 104 (or to the opening 3), but is parallel and moved with respect to it. - Advantageously, in this way the diameter of the
electric motor 7a is not a critical parameter in the dimensioning of thedevice 1, allowing the manufacturer to use motors having different powers according to the needs, without structural limits to the choice. - According to the invention, the
transmission 8 comprises at least a first 9 and asecond wheel 10 rotatably connected to each other, wherein thefirst wheel 9 is rigidly connected to themotor 9 and thesecond wheel 10 has acoupling portion 10a with theshaft 106 or tang of thecylinder 104. - More precisely, the
second wheel 10 is aligned with theopening 3 of the support, preferably disposed along its central axis "B". - According to the invention, the
coupling portion 10a of the second wheel is defined by ahole 11, which can be coupled with theshaft 106 or tang of thecylinder 104 and shaped so as to prevent a relative rotation. - In other words, the
hole 11 is shaped so that theshaft 106 or tang of thecylinder 104 is slidingly insertable therein but is constrained to it during the rotation. - In this respect, the
hole 11 has non-circular section, preferably complementarity shaped to the cross section of theshaft 106 or tang of thecylinder 104. - More preferably, the
hole 11 has at least one flattenedportion 11a, which can be coupled with a corresponding flattenedportion 106a of theshaft 106 or tang. - In the illustrated embodiment, the
hole 11 has a substantially "D"-shaped section or passage. - Advantageously, it is the typical and standard shape of the "tangs" currently on the market, which allows the application of the
device 1 to any pre-existing lock. - Preferably, in order to allow maximum reduction or multiplication of ratios, the
transmission 8 comprises a cascade ofgears 12 extending between the first 9 and thesecond wheel 10. - Therefore, the first 9 and the
second wheel 10 are toothed wheels. - To facilitate the compactness of the device 1 a
plate 13 is provided, having at least a first 13a and asecond face 13b opposite to each other. - The actuator 7, or the
electric motor 7a, and thesupport 2 are connected to and projecting from thefirst face 13a. - The
transmission 8, instead, is associated with thesecond face 13b. Therefore, the cascade of gears 12 (at least the first 9 and the second wheel 10) are pivoted to saidsecond face 13a. - Advantageously, in this way the support 2 (i.e., in use, the
shaft 106 or tang) and themotor 7a are arranged one above the other and abutted to the frame, allowing maximum axial compactness of thedevice 1. - According to the invention, the device comprises a
box body 14 provided with at least a first 13 and asecond plate 15 facing each other and defining a housing for thetransmission 8 therewithin. - Therefore, the
first plate 13 corresponds to the plate described above. Both the first 13 and thesecond plate 15 are provided with respective through holes substantially aligned with thecoupling portion 10a of thesecond wheel 10. - In this way, the
shaft 106 or tang of thecylinder 104 projects from thesecond plate 15 with a free end to which theknob 103 is anchored or anchorable. - Therefore, the device comprises a
box body 14, inside which thetransmission 8 is arranged, asupport 2 and amotor 7a, the latter two elements being both anchored to a same external face of the box body. Advantageously, in this way, the device is compact and robust. - To allow the driving of the actuator 7, the device comprises a
control board 16 associated therewith. -
Such control board 16 is arranged to receive a driving signal from a user and configured to send to saidactuator 7 a signal representative of an opening or a closing of thelock 100 in order to move the actuator. - Structurally, the
control board 16 is constrained to thetransmission 8, so that thetransmission 8 itself is interposed between thetab 16 and said actuator 7. - More precisely, the
control board 16 is abutted, preferably constrained, to thesecond plate 15 of thebox body 14. - Such arrangement further strengthens the concept of compactness that the
driving device 1 described herein aims to achieve. - Note that, also the
control board 16 is provided with its own through hole 16b aligned to the central axis "B" of the support 2 (and hence to the holes of theplates 13, 15). - Preferably, the
control board 16 comprises at least onemicroprocessor 17 or microcontroller, which can be set by the manufacturer to respond to one or more predetermined external or internal signals. - Moreover, the
control board 16 comprises a receivingmodule 18 associated with themicroprocessor 17 or microcontroller and configured to receive a signal sent by an opening element or transponder. - In particular, the
control board 16 is configured to: - compare the signal (received by the transponder) with at least one preset value, and
- send to said
actuator 7 a signal representative of an opening or a closing of thelock 100 as a function of a result of said comparison. - Preferably, the driving
device 1 comprises at least onememory 22 associated with thecontrol board 16 and programmable with the inclusion of one or more reference values (or preset values) corresponding to one or more opening elements (or transponder) - Note that the opening element could also be a smartphone provided with BlueTooth® connection.
- Furthermore, the
device 1 also comprises a communication module associated with thecontrol board 16 and configured to place it in communication with a remote device 109 (as will be better clarified hereafter). - Furthermore, in the preferred embodiments, a signalling module (not shown) is provided connected to the
microcontroller 17. - Similarly, an end-stop striker is also associated with the
control board 16 and configured to detect the position of the frame with respect to the striker, and to prevent the operation of thedevice 1 when the frame is not in abutment. - In the preferred embodiment, the
control board 16 is configured to adapt the movement of the actuator 7 (motor 7a) to the stroke of the lock on which the device is installed. - More precisely, the
control board 16 is configured to measure a parameter representative of the lock stroke from a retracted position of the sliding lock to an end-stop or abutment position. - Preferably, both said positions (retracted and in abutment) are detected in terms of electric current; therefore, the
control board 16 is configured to measure the electric current absorption by the motor 71 and to evaluate a stall current corresponding to a condition of "blocked motor". - In detail, said "stall current" is preset in the control board 16 (or in the microcontroller 17) and is limited to an acceptable value by acting on the control of the drive pulses (PWM signal, Pulse Width Modulation).
- In the preferred embodiment, the
device 1 comprises a timer associated with thecontrol board 16 and configured to measure at least the time between said retracted position and said abutment position of the motor. - Said
control board 16 is thus arranged, in a learning configuration, to receive a signal representative of such time in order to determine the activation time of the actuator 7 necessary to a complete closing/opening of the lock. - Said learning configuration is maintained by the control board at least to a first switching on of the
device 1. - Subsequently to said first switching on, the
control board 16 switches into an operating configuration, in which it drives the actuator 7 in opening or closing for a time equal to, preferably slightly lower than, the detected value in said learning configuration. - Advantageously, in this way the sliding lock is not brought in abutment, with advantages from the point of view of the user's liking and the wear of the system.
- Moreover, in the preferred embodiment the
control board 16 is configured to activate periodically the "learning" configuration, in order to update said time value. - The update period may be temporally fixed, through said timer, or (preferably) linked to the cycle number of opening/closing of the device through, for example, a counter associated with the tab.
- Advantageously, this allows compensating the mechanical parameters variations of the motorized system, due to the wear or settling of the components in motion and to the effects of the room temperature and the internal temperature on the system itself to allow the device operation without the need to perform masonry works. The
device 1 also comprises abattery 20 connected to the actuator 7 and/or to thecontrol board 16. Such battery may be connected to the device in a removable or irremovable way. - In the second case, the
battery 20 should be rechargeable in situ by a cable or connector, which is extractable or externally faceable to thedevice 1. - Alternatively, or in combination, the
battery 20 is connected in a reversible way to the actuator 7 and/or to thecontrol board 16 in order to allow its replacement. - Thus, in the preferred embodiment the
battery 20 is provided with a reversible connector, which can be coupled with a respective socket formed in or associated with thecontrol board 16. More preferably, sliding contacts are used. - Preferably, the
device 1 comprises a coveringelement 21, which can be anchored to the frame. - This covering
element 21 preferably has a first 21a and asecond concavity 21b adjacent to each other. - In the
first concavity 21a are housed, in use, thesupport 2 and the gear motor 6 (and the control board 16). - In the
second concavity 21b is instead housed, in use, thebattery 20. Preferably, the covering element has two separable half-parts, each defining a concavity. - Advantageously, in this way, it is possible to replace the
battery 20 without the need to remove thedevice 1 or its covering. - As mentioned above, the
device 1 preferably is inserted into an electronic system for driving thelock 100. - Preferably, the system is composed of the
device 1, at least oneremote server 200 and at least oneremote device 201. - The
remote server 200 is therefore operatively interposed, from a point of view of the communication and data transfer, between thedevice 1 and theremote device 201. - It is connected to the
control board 16 of thedevice 1 through the communication module mentioned above. - Note that the expression "
remote device 201" herein refers to any programmable electronic device through which it is possible to connect remotely to the server and interface with thecontrol board 16 of the device, such as, for instance, a PC, a smartphone, a tablet, or the like. - In this respect, the
remote device 201 is provided with aprogramming interface 202 connectable to the communication module of thedevice 1 through saidserver 200. - Preferably, the
programming interface 202 is defined by a web application or software, which can be installed or downloaded by a user on theremote device 201 through the common channels used. - Such
remote device 201, through theprogramming interface 202, is therefore configured to exchange data with thedriving device 1 in order to display the condition of thelock 200 and/or to allow an operator to set one or more operating parameters of the thedriving device 1 itself. - In a first functionality, the
programming interface 202 comprises at least aselection module 203 operable by a user control interfaced with saidremote device 201, and configured to send to saidcontrol board 16 of the device 1 a signal representative of an opening or closing condition of thelock 100. - Advantageously, in this way, an enabled user can remotely open or close the
lock 100, resolving numerous problems and daily uncertainties related to the need for currently verifying in situ the correct closing or opening of the lock, or the need for constantly verifying the possession of the keys. - In a further functionality, independent but preferably complementary to the previous one, the
programming interface 202 comprises at least onemanagement module 204 activated by a command of a user interfaced with saidremote device 201. -
Such management module 204 is configured to enable or disable one or more opening elements (or transponders) through an insertion or a deletion of the respective opening element into or from saidmemory 22. Similarly, theprogramming interface 202 may comprise, in turn, a memory 202a in which one or moreremote devices 201 enabled to the use of thedriving device 1 are insertable and disinsertable, through specific encoding. - Preferably, moreover, the
management module 204 is arranged to allow the creation and/or modification and/or deletion of personal profiles provided with respective identification parameters enabled for opening thelock 200. - The invention achieves the intended objects and achieves important advantages.
- In fact, the presence of a motor coaxial to the opening of the support allows reducing the overall dimensions of the device, making it easily coupled to all the existing locks.
- Moreover, the presence of a transmission with perforated wheel in which the tang of the existing cylinder is slidably insertable makes the device easily to assemble and intuitive.
- Furthermore, the presence of a remote interface that allows both the activation and the enabling of the transponders to the use of the device, makes the system safe and easily to control.
