[0001] The present invention relates to an electronic device for driving a lock and an electronic
lock comprising said device.
[0002] Therefore, the present invention finds particular application in the field of security,
and in particular in products for public or private building security.
[0003] 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.
[0004] In this respect, electric and electronic locks are well known, in which the cylinder
rotation is imparted by drives or suitably controlled electric motors.
[0005] 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.
[0006] Disadvantageously, this kind of coupling forces the manufacturer to a predetermined
positioning of the motor and limits also the freedom in its dimensioning.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] Said objects are achieved by an electronic device for driving a lock according to
claim 1 and by an electronic lock according to claim 12.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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).
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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

[0027] With reference to the appended figures, number 1 indicates a device for driving a
lock 100 according to the present invention.
[0028] The lock 100 is assembled or integrated in a frame or door, preferably outdoor.
[0029] The lock 100 thus comprises a box body 102 inserted (or insertable) in a recessed
area formed in the frame .
[0030] In the box body 102 a plurality of sliding locks and the set of (upper and/or lower)
rods are provided, all moved by a moving mechanism, not illustrated nor described
in detail as known
per se.
[0031] In the lock 100 is also provided a latch bolt, preferably operable also by means
of a handle.
[0032] Preferably, both the latch bolt and the mechanism are operable via the lock 100 both
manually, through a key or a knob 103, and by means of the device 1 according to the
present invention.
[0033] In any case, the lock 100 comprises a cylinder 104 inserted in the frame and extending
along its own main extension axis "A" which, in use, is preferably horizontal.
[0034] In the illustrated embodiment, the cylinder 104 comprises at least a first 104a and
a second half-part 104b arranged in succession along said extension axis "A".
[0035] The first half-part 104a of the cylinder 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.
[0036] The second half-part 104b of the cylinder 104, instead, has a shaft 106 or tang extending
along the extension axis "A" away from the first half-part 104a.
[0037] Preferably, the shaft 106 or tang is connected to the rotatable portion of the first
half-part 104a, in series to it.
[0038] Note that the shaft 106 has a free end, distal from the first half-part 104a, shaped
to couple with a rotatable knob 103 suitable for allowing a quick opening/closing
of the lock from the inside environment.
[0039] 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.
[0040] In this regard, the shaft 106 or tang has at least one flattened portion of rotational
coupling with the knob 103.
[0041] 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 the shaft 106 or
tang.
[0042] The projecting portion is thus part of the second half-part 104b.
[0043] The electronic device 1 for driving the lock 100 is coupled, in use, to the cylinder
104 and in particular to the above projecting portion.
[0044] According to the invention, the electronic device 1 comprises a support 2 for connection
with the cylinder 104 of the lock 100.
[0045] Such support 2 has at least one through opening 3 for receiving the aforementioned
projecting portion of the cylinder 104 and fastening means 4 to block the support
2 with respect to the projecting portion.
[0046] More precisely, the opening 2 is shaped so as to fit on the projecting portion, and
the fastening means 4 are configured to block the support 2 on the projecting portion.
[0047] Therefore, the opening 3 extends crossing the support 2 along a central axis "B"
which, in use, is parallel (or corresponding) to the extension axis of the cylinder
104.
[0048] In the preferred embodiment, the support 2 is defined by a plate 5 provided with
a hole 5a substantially complementarity shaped to the projecting portion of a common
European cylinder lock 100 and defining said opening 3.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] The support 2 is also connected to a gear motor 6 provided with an actuator 7 and
a transmission 8.
[0053] Such gear motor 6 is configured to rotate the cylinder 104 and allow the opening
or closing of the lock 100.
[0054] 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 the cylinder 104.
[0055] 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.
[0056] Advantageously, in this way the diameter of the electric motor 7a is not a critical
parameter in the dimensioning of the device 1, allowing the manufacturer to use motors
having different powers according to the needs, without structural limits to the choice.
[0057] According to the invention, the transmission 8 comprises at least a first 9 and a
second wheel 10 rotatably connected to each other, wherein the first wheel 9 is rigidly
connected to the motor 9 and the second wheel 10 has a coupling portion 10a with the
shaft 106 or tang of the cylinder 104.
[0058] More precisely, the second wheel 10 is aligned with the opening 3 of the support,
preferably disposed along its central axis "B".
[0059] According to the invention, the coupling portion 10a of the second wheel is defined
by a hole 11, which can be coupled with the shaft 106 or tang of the cylinder 104
and shaped so as to prevent a relative rotation.
[0060] In other words, the hole 11 is shaped so that the shaft 106 or tang of the cylinder
104 is slidingly insertable therein but is constrained to it during the rotation.
[0061] In this respect, the hole 11 has non-circular section, preferably complementarity
shaped to the cross section of the shaft 106 or tang of the cylinder 104.
[0062] More preferably, the hole 11 has at least one flattened portion 11a, which can be
coupled with a corresponding flattened portion 106a of the shaft 106 or tang.
[0063] In the illustrated embodiment, the hole 11 has a substantially "D"-shaped section
or passage.
[0064] 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.
[0065] Preferably, in order to allow maximum reduction or multiplication of ratios, the
transmission 8 comprises a cascade of gears 12 extending between the first 9 and the
second wheel 10.
[0066] Therefore, the first 9 and the second wheel 10 are toothed wheels.
[0067] To facilitate the compactness of the device 1 a plate 13 is provided, having at least
a first 13a and a second face 13b opposite to each other.
[0068] The actuator 7, or the electric motor 7a, and the support 2 are connected to and
projecting from the first face 13a.
[0069] The transmission 8, instead, is associated with the second face 13b. Therefore, the
cascade of gears 12 (at least the first 9 and the second wheel 10) are pivoted to
said second face 13a.
[0070] Advantageously, in this way the support 2 (i.e., in use, the shaft 106 or tang) and
the motor 7a are arranged one above the other and abutted to the frame, allowing maximum
axial compactness of the device 1.
[0071] According to the invention, the device comprises a box body 14 provided with at least
a first 13 and a second plate 15 facing each other and defining a housing for the
transmission 8 therewithin.
[0072] Therefore, the first plate 13 corresponds to the plate described above. Both the
first 13 and the second plate 15 are provided with respective through holes substantially
aligned with the coupling portion 10a of the second wheel 10.
[0073] In this way, the shaft 106 or tang of the cylinder 104 projects from the second plate
15 with a free end to which the knob 103 is anchored or anchorable.
[0074] Therefore, the device comprises a box body 14, inside which the transmission 8 is
arranged, a support 2 and a motor 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.
[0075] To allow the driving of the actuator 7, the device comprises a control board 16 associated
therewith.
[0076] Such control board 16 is arranged to receive a driving signal from a user and configured
to send to said actuator 7 a signal representative of an opening or a closing of the
lock 100 in order to move the actuator.
[0077] Structurally, the control board 16 is constrained to the transmission 8, so that
the transmission 8 itself is interposed between the tab 16 and said actuator 7.
[0078] More precisely, the control board 16 is abutted, preferably constrained, to the second
plate 15 of the box body 14.
[0079] Such arrangement further strengthens the concept of compactness that the driving
device 1 described herein aims to achieve.
[0080] 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 the plates 13,
15).
[0081] Preferably, the control board 16 comprises at least one microprocessor 17 or microcontroller,
which can be set by the manufacturer to respond to one or more predetermined external
or internal signals.
[0082] Moreover, the control board 16 comprises a receiving module 18 associated with the
microprocessor 17 or microcontroller and configured to receive a signal sent by an
opening element or transponder.
[0083] 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 the
lock 100 as a function of a result of said comparison.
[0084] Preferably, the driving device 1 comprises at least one memory 22 associated with
the control 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)
[0085] Note that the opening element could also be a smartphone provided with BlueTooth®
connection.
[0086] Furthermore, the device 1 also comprises a communication module associated with the
control board 16 and configured to place it in communication with a remote device
109 (as will be better clarified hereafter).
[0087] Furthermore, in the preferred embodiments, a signalling module (not shown) is provided
connected to the microcontroller 17.
[0088] 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 the device 1 when the frame is not in abutment.
[0089] 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.
[0090] 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.
[0091] 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".
[0092] 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).
[0093] In the preferred embodiment, the device 1 comprises a timer associated with the control
board 16 and configured to measure at least the time between said retracted position
and said abutment position of the motor.
[0094] 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.
[0095] Said learning configuration is maintained by the control board at least to a first
switching on of the device 1.
[0096] 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.
[0097] 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.
[0098] Moreover, in the preferred embodiment the control board 16 is configured to activate
periodically the "learning" configuration, in order to update said time value.
[0099] 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.
[0100] 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 a battery 20 connected to the actuator 7 and/or to the control
board 16. Such battery may be connected to the device in a removable or irremovable
way.
[0101] In the second case, the battery 20 should be rechargeable
in situ by a cable or connector, which is extractable or externally faceable to the device
1.
[0102] Alternatively, or in combination, the battery 20 is connected in a reversible way
to the actuator 7 and/or to the control board 16 in order to allow its replacement.
[0103] 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 the control
board 16. More preferably, sliding contacts are used.
[0104] Preferably, the device 1 comprises a covering element 21, which can be anchored to
the frame.
[0105] This covering element 21 preferably has a first 21a and a second concavity 21b adjacent
to each other.
[0106] In the first concavity 21a are housed, in use, the support 2 and the gear motor 6
(and the control board 16).
[0107] In the second concavity 21b is instead housed, in use, the battery 20. Preferably,
the covering element has two separable half-parts, each defining a concavity.
[0108] Advantageously, in this way, it is possible to replace the battery 20 without the
need to remove the device 1 or its covering.
[0109] As mentioned above, the device 1 preferably is inserted into an electronic system
for driving the lock 100.
[0110] Preferably, the system is composed of the device 1, at least one remote server 200
and at least one remote device 201.
[0111] The remote server 200 is therefore operatively interposed, from a point of view of
the communication and data transfer, between the device 1 and the remote device 201.
[0112] It is connected to the control board 16 of the device 1 through the communication
module mentioned above.
[0113] 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 the control board 16 of the device, such as, for instance, a PC, a smartphone,
a tablet, or the like.
[0114] In this respect, the remote device 201 is provided with a programming interface 202
connectable to the communication module of the device 1 through said server 200.
[0115] Preferably, the programming interface 202 is defined by a web application or software,
which can be installed or downloaded by a user on the remote device 201 through the
common channels used.
[0116] Such remote device 201, through the programming interface 202, is therefore configured
to exchange data with the driving device 1 in order to display the condition of the
lock 200 and/or to allow an operator to set one or more operating parameters of the
the driving device 1 itself.
[0117] In a first functionality, the programming interface 202 comprises at least a selection
module 203 operable by a user control interfaced with said remote device 201, and
configured to send to said control board 16 of the device 1 a signal representative
of an opening or closing condition of the lock 100.
[0118] 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.
[0119] In a further functionality, independent but preferably complementary to the previous
one, the programming interface 202 comprises at least one management module 204 activated
by a command of a user interfaced with said remote device 201.
[0120] 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 said memory 22. Similarly, the programming interface 202 may
comprise, in turn, a memory 202a in which one or more remote devices 201 enabled to
the use of the driving device 1 are insertable and disinsertable, through specific
encoding.
[0121] 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 the lock 200.
[0122] The invention achieves the intended objects and achieves important advantages.
[0123] 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.
[0124] 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.
[0125] 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.
