Definitions
- the present disclosure concerns operation of a lock comprising an electronic utility that is operable upon communication with a user device.
- locks that are intended to wirelessly pair with a user device, e.g. a smartphone with a proper application running therein, and upon such pairing that requires sending out and receiving coded signals between the lock and the device, the lock opens.
- a user device e.g. a smartphone with a proper application running therein
- the lock opens.
- One is of a kind that continuously transmits a Bluetooth data signal and when an authorized user- device is in the vicinity, it receives the data signal, decodes it and sends out a coded response signal that when received in the lock and decoded therein causes the lock to open.
- this continuous transmission can rapidly drain the battery within the lock.
- Another type of lock that opens upon Bluetooth pairing requires the user to do a separate operation, e.g. press a button or a keypad that wakes the electronic utility of the lock to initiate the pairing process.
- the present disclosure provides a lock, particularly a cylinder lock that may be fitted into doors or other closures.
- the lock of this disclosure is secure in that it can only be opened by an authorized user, on the one hand, and is operable in a natural way without the need for physically inputting any code by the authorized user or separately "waking up” the electronic utility within the lock, on the other hand.
- An authorized user is one equipped with a user device (“user device") that can pair with the electronic utility within the lock to open the lock ("an authorized user device”); namely a user device that can or is configured to receive a first, typically encrypted signal from the lock's electronic utility and in response transmit a second, lock-specific opening signal, also typically encrypted, to the lock that once received by the lock induces it to open.
- the user device may be a dedicated device; or a mobile communication device, e.g. a smartphone that runs an application that configures the smartphone to receive the first signal from said electronic utility, decrypt the signal, and then issue the second, encrypted signal to said electronic utility.
- This opening signal causes the electrically operated mechanism within the lock to displace an engagement mechanism that couples the lock mechanism with an external user-accessible unit of the lock, thereby permitting opening of the lock by operation of said external user- accessible unit.
- the authorized user operates the lock in the same manner he would operate the lock had it been open already, oblivious to the fact that his action on the user-accessible unit initially activates the electronic utility within the lock that leads to wireless pairing (e.g. via the Bluetooth protocol) with an authorized user and consequently opening of the lock.
- the security of the lock is maintained by encryption of either or both of (i) the first signal that is transmitted by the lock's electronic utility to the user device and being decodable therein and (ii) the second signal transmitted by the user device in response to that received from the lock, that is decrypted by a coding/decoding module within the lock's electronic utility and induces the activation of the electrically operated mechanism.
- the signals transmitted by the lock or received thereby may be a variable signal, according to a predetermined sequence, such as that disclosed in PCT Applications WO 2014/0006615 and PCT/IL2015/050384, the relevant parts of which are incorporated herein by reference.
- the lock can be opened by a user in a natural manner without the need for the user to physically input a code for activating the lock, as long as he/she carries the proper user device.
- the signals that are communicated may typically be wireless electromagnetic signals, e.g. employing the Bluetooth communication protocol but, as will be appreciated, the disclosure is not limited to any specific type of signal.
- the user device may be configured for permanent pairing with the lock's electronic utility, may be configured for a limited number of pairings with the lock, may be configured for pairing at a defined time window, may be configured for pairing with a number of locks, etc.
- a lock comprising an external user-accessible unit for opening the lock, an electronic utility that is configured for wirelessly pairing with a user device, and an electromechanical assembly for switching the lock from the locked to the open state upon receipt of an appropriate command from the electronic utility.
- the external user-accessible unit is configured for operation in a two-stage process, of which the first stage activates the electronic utility to thereby pair with a user device and the second stage, seamlessly continuous with the first stage, opening the lock in the presence of an authorized user device.
- the electronic utility is configured for (i) transmitting one or more first wireless signals, (ii) receiving one or more second wireless signals from a user device and (iii) in the event of receipt of a signal from an authorized user device (e.g.
- pairing in the context of this disclosure, denotes a wireless (e.g. optical, IR, RF, Bluetooth) establishment of communication between the lock's electronic utility and the user device using a communication protocol that is intended, in the event the device is an authorized device, to induce the electronic utility to issue said command signal.
- wireless e.g. optical, IR, RF, Bluetooth
- the disclosure provides a lock that comprises an external user-accessible unit, a lock mechanism with locking element, an electronic utility and an electromechanical engagement assembly.
- Said engagement assembly comprises an electric sub-assembly that drives a mechanical sub-assembly adapted to engage the lock mechanism or an element thereof to thereby block coupling of said unit with locking element.
- the electronic utility is electrically coupled to said electric sub-assembly and comprises a trigger element (that may, for example, comprise a micro-switch), and is configured for (i) wireless pairing with an authorized user device and (ii) issuing, upon pairing, a lock-activation signal to activate the electric sub-assembly, to thereby drive the mechanical sub-assembly to couple the external user-accessible unit with the locking element.
- the pairing may be through a communication protocol that includes one or more first signals transmitted by the electronic utility and one or more second signals transmitted by the user device in response thereto.
- the communication may be entirely encrypted or may be partially open and partially encrypted (e.g.
- the signal transmitted by the electronic utility may be open while that transmitted by the user device may be encrypted and then decrypted by a module of the electronic utility).
- the lock will open only upon receipt of the proper (typically encrypted) lock opening code from the user device.
- the electronic utility may include a transceiver module or separate transmitter and receiver modules. Upon pairing and receipt of a lock opening signal from the user device, the electronic utility activates said electric sub-assembly to thereby drive the mechanical sub-assembly.
- the external user-accessible unit (i) is operable by a user to open the lock, (ii) is coupled to the trigger element such that a first stage of the operation actuates the trigger element, and (iii) is capable of coupling to the locking element upon activation of the electric sub-assembly.
- said electronic utility Upon pairing with the user device, said electronic utility activates the electric sub-assembly to drive the mechanical sub-assembly to thereby cause coupling of said external user-accessible unit with said locking element such that a second stage of said operation, substantially continuous with said first stage, opens the lock.
- substantially continuous denotes that the opening of the lock by the user is smooth and proceeds in a natural way as if opening an unlocked lock; although by some embodiments there may be some delay, e.g. fraction of a second, until full engagement and coupling between the external user-accessible unit and the lock mechanism. This may mean, for example, that the lock operates with the need for a user to perform a first operation stage to cause engagement of the external user-accessible unit with the lock mechanism, followed by a second operation stage after such engagement.
- the user would be oblivious to the fact (save for a potential click, vibration or other mechanical indication that the engagement mechanism emits in its operation) that an essentially two-stage procedure actually occurs.
- the two-stage procedure would occur internally within the lock in tandem with a natural operation of the lock as if the lock would have been a priori unlocked.
- said external user-accessible unit is at an exterior lock end intended for positioning at an exterior side of a closure (e.g. an entrance door) and the lock comprises an internal user-accessible unit at the opposite, i.e. interior lock end, operable by the user inside the closure.
- the electromechanical assembly and the electronic utility are typically housed within said internal user- accessible unit.
- at least one of the external and internal use- accessible units is a knob or a handle.
- both the external and internal use-accessible units are in the form of a knob.
- Said engagement assembly may be adapted to engage an element of the lock mechanism (e.g. by some embodiments being a plunger, as discussed below) that may be configured such that, upon displacement, the engagement assembly can couple and decouple (depending on the displacement direction) between said external user- accessible unit and the locking element. Any arrangement that can induce such coupling and decoupling may be used in accordance with the disclosure.
- an element of the lock mechanism e.g. by some embodiments being a plunger, as discussed below
- the engagement assembly can couple and decouple (depending on the displacement direction) between said external user- accessible unit and the locking element. Any arrangement that can induce such coupling and decoupling may be used in accordance with the disclosure.
- the electric sub-assembly may comprise a solenoid, an electric motor or a piezoelectric element.
- said engagement assembly engages the lock mechanism or an element thereof and released said lock mechanism or element upon activation to thereby couple the external user-accessible unit with the locking element.
- the coupling of the external user-accessible unit and the locking element is rotational.
- the lock mechanism comprises, by an embodiment of this disclosure, a plunger extending internally along an axis within the lock between the external and internal user-accessible units and having a first end proximal said external user-accessible unit and second end proximal said internal user-accessible unit.
- the plunger is axially displaceable between a reward state, in which its second end is engaged by an engagement element of the mechanical sub-assembly, and being biased into a forward state in which it couples the external user-accessible unit to the locking element.
- the engagement element may be a revolvable element that is coupled to an electric motor that revolves said element between an engaging state, in which it engages the second plunger end, and a releasing state in which it permits the plunger's displacement to its forward state.
- the plunger may be configured for rotational engagement of the external user- accessible unit upon axial displacement to its forward state, to thereby rotationally couple said unit with the locking element.
- the plunger may be configured for rotational engagement of the locking element upon axial displacement to its forward state, to thereby rotationally couple said unit with the locking element.
- the electronic utility comprises a first sensor, e.g. optic sensor or mechanical sensor, for monitoring the status of at least one of mechanical sub-assembly or the engagement element. It may also comprise a second sensor for providing indication of the locking status.
- the locking status may be an (i) indication of the status of an element in the mechanical sub-assembly that is indicative of whether the lock is open or locked, (ii) indication of the status of the engagement element, and/or (iii) may be a direct indication of the status of the locking element.
- the external user-accessible unit is a knob or handle operated by rotation.
- the first stage of the rotation may cause the actuation of the trigger element and hence the activation of the electronic utility, and the second stage, e.g. continuing smoothly from the first stage without any need for a user to temporary halt the rotation to then proceed to the second stage.
- the operation of the lock which mechanistically proceeds in the aforementioned two distinct sequences, will be externally seen and felt by a user as one operation.
- the external user-accessible unit is a retractable - extendible handle or knob that (i) can be pressed to activate the signal-transmitting module, and (ii) extends, upon receipt of the lock activation signal by the electronic utility to permit user operation for opening the lock.
- the knob may (i) axially reciprocate between a retraced state in which it is accommodated within a recess in the lock and an extended state in which is extends out of said recess and accessible to a user, and (ii) may be displaced into the extended state by the displacement of said plunger into its forward state.
- the first stage of the operation will, thus, involve pressing on knob or handle to thereby actuate the trigger element and hence activate the electronic utility and while the plunger extends, e.g. as a result of the electrically operated mechanism induced release of a spring-biased latch, the external user-accessible unit is coupled with the lock mechanism; and once the external user-accessible unit extends, the lock can be opened. Again, this operation proceeds as if the lock would have been a priori unlocked.
- the activation of the signal transmitting module may lead to substantial simultaneous extension of said external user-accessible unit and activation of the electronic utility; or the extension and said engagement may be one operation induced by said electronic utility.
- the retractable-extendible unit comprises a pair of wings that have a housed state, in which they are housed in a radial bore passing radially through said unit, and have a deployed state in which they extend radially out of the bore in opposite radial directions and are biased into the deployed state.
- the pair of wings are deployed, bettering the user's grip of the unit as compared to such a unit without the wings.
- a lock comprising a user-accessible, axially retractable and extendible unit with such wings is an independent aspect of this disclosure, even if outside the context of a lock of the kind described above.
- Causing extension from the retracted state into the extended state may be achieved by axially pushing said unit in the opposite direction and releasing, whether through the pairing mechanism described above or a mechanical or electromechanical arrangement, e.g. of a kind as known per se.
- at least one of the data signals typically at least that transmitted by the user device that can induce the electronic utility to issue said command signal, may be encrypted and accordingly the electronic utility may comprise at least one of a data signal encryption module for encrypting the transmitted wirelessly transmitted signal and a signal decrypting module for decrypting the wirelessly received signal.
- first signal will be used to denote the one or more data signals wirelessly transmitted by the lock's electronic utility
- second signal will be used to denote the one or more data signals wirelessly transmitted by the user device.
- the first and second signals are intended to pair the lock's electronic utility with the user device.
- the electronic utility may comprise a wireless transceiver for transmitting first signals and for receiving second data signals.
- the electronic utility may also comprise data storage for storing series of codes, which may be codes used in a certain predetermined sequence, codes used for specific timeframes, etc.
- Such security enhancing features may include, for example, encrypted signals that are specific for a defined time window to operate the lock, or a specific lock within a plurality of locks.
- the user device may be equipped with a location identifying functionality, e.g. one based on a global positioning system (GPS), such as a typical GPS software application typically installed in mobile communication devices and is configured to deliver one or more lock-specific data signals (in response to one or more data signals from the lock's electronic utility) in a location-specific manner.
- GPS global positioning system
- This permits accurate monitoring of the user device's position and its management based thereon; for example permitting generation of a second, lock-opening signal only if and when the user device is in the vicinity of a specific lock (i.e. geo-fencing).
- the electronic utility of the lock may include a processor module that may be pre-programmed with a plurality of access codes, or such codes may be stored in a memory being part of or associated with the processor module.
- One or more of such codes may then be transmitted as the first data signal from the electronic utility's signal-transmitting or transceiver module to the user device.
- each first signal may be an encrypted single use code to be used one time only and then deleted from, inactivated or marked as used in the processor. It is also possible, under some embodiments, particularly in high security applications, to require a combination of two or more encrypted signals or codes, e.g. at a defined interval, for opening the lock.
- the controller may further deliver encrypted data signals that may include other components to the user device to further be received by the signal-receiving utility of the lock.
- the second signals may encode instructions that define operational parameters of the lock's processor module.
- the operational parameters may be a control code for subsequent opening of the lock, may be change of operational parameters, change of functions, a new series of access control permissions, and others.
- any desired instruction to or any desired programming of the lock's processor module may thereby be delivered without the need to connect the lock to an on-line system or without the need to connect any physical devices to the lock for data transmission.
- the electronic utility is normally in a dormant state and is activated by the trigger element upon initial operation of the external user-accessible unit. Once activated, the electronic utility, by some embodiments, may issue an open/closed indication signal that may be received by the user device and may provide the locking status indication to the user.
- the locking status indication may be transmitted by the user device to a central controller or server, e.g. via wireless communication or over a cellular network.
- the signal-transmitting module of the lock is adapted to continuously transmit a lock's status to the user device, i.e.
- Such open/lock status indication may permit to monitor the status of the lock, even in the case of an off-line lock; to monitor the specific code that was used for a specific opening, in the case of high security installation where the code is intended to serve for a single use; to issue a reminder to the user to lock the lock in case this was accidentally omitted; etc.
- the opening may be for a defined time period and if the opening sequence is not continued, the engagement mechanism may disengage the external user-accessible unit from the lock mechanism.
- the engagement may be active as long as the lock is in the open state to permit locking of the lock.
- the electromechanical assembly causes disengagement of the lock mechanism from the external user- accessible unit.
- the lock may automatically switch to a locked state, in which the external user-accessible unit is disengaged from the lock mechanism after a defined time period of engagement.
- a door that includes such a lock may have an internal handle, knob, etc. (i.e., the internal user- accessible unit) that permits a user to open the lock from the inside, even when the lock is in the locked state.
- access from the outside will require a communication exchange sequence between the lock and the user device, as described above, while access from the inside may not.
- the same mechanism will operate also for opening from the inside.
- one of the features of the disclosure is that it does not require the user to physically input any code, whether to the lock or whether to the user device.
- the whole operation is practically automatic, namely, once the user moves said external user-accessible unit, the first stage of the movement induces the entire activation process that results in the engagement of said external user-accessible unit with the lock mechanism and the second stage opens the lock.
- These two stages may be substantially continuous; namely other than potentially hearing a click indicative of activation of the engagement mechanism, the opening will be natural as if using a regular door handle or knob.
- first stage and second stage is only from an internal lock operation sequence point of view and is not meant to indicate two discrete user-operated stages of moving said external user-accessible unit. On the contrary, these two “stages” are substantially non-discernible by the user are substantially one continuous movement of said unit.
- the disclosure provides a system comprising (i) a lock of the kind described above; and (ii) a user device containing application software that can configure the device to receive said first signal and issue said second signal.

- Fig. 1 shows a rotation-activated lock 100, according to an embodiment of this disclosure. It comprises an external user accessible unit 102, cylinder 104, with locking element in the form of a cam 106, and an internal user accessible unit 108.
- a closure element e.g. a bolt
- FIG. 2A and 2B A pressure-activated lock according to an embodiment of this disclosure is illustrated in Figs. 2A and 2B.
- Figs. 2A, 2B and generally throughout this disclosure the same reference numerals shifted by 1000 will be used to refer to elements in the pressure-activated lock embodiment that are functionally equivalent and at time structurally similar to elements in the rotation-activated lock embodiment.
- element 1102 in Fig. 2A is functionally equivalent to element 102 in Fig. 1.
- the description will not be repeated when describing the pressure-activated lock embodiment and the reader should refer to the description of the rotation-activated embodiment for explanations on their structure and function.
- Lock 1000 is seen in a locked state (Fig. 2A) and in an open state (Fig. 2B).
- Lock 1000 includes a user accessible unit 1300 which in the closed state of Fig. 2A is retracted and accommodated within recess 1302 formed in cylinder portion 1304; and in the open state is extended, as seen in Fig. 2B, the extension being effected by a mechanism to be described below.
- unit 1300 has two opposite wings 1306, 1308 that are biased to deploy into the opened state shown in Fig. 2B and thus automatically deploy when unit 1300 is extended out of recess 1302.
- portion 1304 is separated from the remaining portions of cylinder 1104 by gap 1310 that is bridged by integral bridge portion 1312.
- the two portions are held together also by a looped metal band wrapped around two vertical pins (not shown in Figs. 2A and 2B. but can be seen in Figs. 8A, 8B and marked there 1316 and 1318).
- This arrangement is designed as a means against tampering. In the event of tampering event by somehow grabbing and shaking unit 1300 or portion 1304, bridge 1312, which is the weak point of link between portion 1304 and cylinder 1104, will break. However such shaking will not affect other elements of the lock, particularly the elements responsible for coupling between the plunger and the cam that, as will be explained below, functionally couples between unit 1300 and cam 1106.
- the internal user accessible unit 108 houses an electro-mechanical assembly, generally designated 110 and also an electronic utility 112.
- the electro-mechanical assembly includes an electric sub-assembly that comprises a battery 114, electric motor 116 with its associated gear box 118 that is rotationally coupled to mechanical sub-assembly 120 (whereby activation of the motor rotates the mechanical sub-assembly 120.
- the mechanical sub-assembly comprises an integral engagement element 122.
- the electronic utility 112 better seen in Figs. 3A and 3B, includes a PCB board 124 holding a trigger element in the form of micro-switch 126 having a lever 128.
- the electronic utility is electrically coupled through leads (see Fig.
- plunger 130 Accommodated within cylinder 104 is plunger 130 that has two parts: a front part 132 and a rear part 134 that are axially threaded to one another at 135.
- the two part structure of plunger 130 is dictated by considerations of assembling the lock, although functionally the plunger operates as one unit
- Plunger 130 is accommodated in an elongated axial bore 136 formed within block 137 with a front portion 138, a narrower, mid-portion 140 and a rear portion 141. Plunger 130 can axially reciprocate within the bore 136, between the rear position in the closed state of Fig. 4A and the forward position in the open state of Fig. 4B.
- the plunger is forwardly biased in the direction of arrow 142 by an associated spring 144 fitted around the plunger and accommodated between step 146 at the rear end of bore portion 138 and shoulders 148 of the plunger.
- the rear part 134 of the plunger has a wider portion 150 that limits the forward displacement of the plunger upon engagement with step 151 at the front end of bore portion 141.
- the front end section 152 which is forward to shoulders 148, has a rear end portion 154 with a generally rectangular cross-section and a front portion 156 with rounded narrow side faces defined between broader parallel straight faces.
- cam 106 defined within cam 106 is a rectangular bore 158, so dimensioned that when portion 154 fits into bore 158, the cam and the plunger become rotationally coupled.
- the cross-sectional dimension of portion 156 is such that when within bore 158, the plunger and the cam are rotationally decoupled, namely, the plunger can freely rotate with respect to the cam, without causing rotation of the latter. This decoupled state is seen in Fig. 4A.
- the front end portion 156 of the plunger is accommodated within recess 160 formed within member 162, which is shaped to match the shape of portion 156 and consequently member 162 and the plunger are rotationally coupled.
- Member 162 can rotate within cylinder 104 and is rotationally coupled to external user accessible unit 102.
- rotation of unit 102 will rotate member 162 and hence the plunger 132 (without rotation of cam 106).
- Integrally formed at the rear end of plunger part 134 is an arresting member 170 that is integral with and projects radially from the rear end of the plunger to define shoulders 172 that rest against engagement element 122. The engagement and disengagement between arresting member 170 and the engagement element 122, as well as the structure of the engagement element are best seen in Figs. 5D and 5E.
- Engagement element 122 has an integral, generally radially projecting engagement member 167, which has a slanted rear face 165 defined between a narrow first end 163 and a broad second end 161.
- shoulders 172 of arresting member 170 rest against end 161 of the rear face 165 of member 167.
- the plunger 130 is forwardly displaced to the position seen in Figs. 4B and 5E (by the biasing action of spring 144).
- portion 154 comes to rest within bore 158, whereby plunger 130 becomes rotationally coupled to cam 106 and consequently rotation of unit 102 will rotate the cam to thereby open a bolt (or the like) of the closure in which the lock if installed.
- the arresting member 170 has a general annular shape and a rear face 173 that is gradually slanted in both directions between a narrow side 176 and a wide, opposite side 178.
- lever 128 rests against said rear face.
- micro-switch 126 will activate the electronic utility 112.
- This activation induces the electronic utility to transmit (through a transmitter or transceiver module thereof) a first, encrypted wireless signal to a user device and in the event said device is properly configured (e.g.
- the switch between the open state of Figs. 4B, 5B and 5E to the locked state of Figs. 4A, 5A and 5D proceed automatically, typically after a time window sufficient for a user to open the lock, such time window may be several seconds to tens of seconds.
- a time window sufficient for a user to open the lock
- the electronic utility will cause reactivation of the electric sub-assembly, whereby electric motor 116 will rotate in the opposite direction, thereby rotating engagement element 122 in the direction opposite to arrow 174.
- the narrow first end 163 of the engagement member will come into position below shoulders 172 and the ongoing rotation and engagement between rear face 165 and shoulders 172 will cause rear-ward displacement of the plunger and consequently decoupling between unit 102 and the cam.
- Engagement element 122 is part of a mechanical sub-assembly 120 which, as can be seen in Figs. 4A and 4B, consists in addition to engagement element 122, also of a motor coupled member 181 and a mechanical buffer arrangement 179 there-between. Member 181 is rotationally coupled to motor 116 through axial 177.
- the buffer arrangement has the capability to store some of the mechanical energy of the motor and then transfer it to the engagement element. This, among others, serves to protect the motor against damage that may have been imparted had the motor been connected directly to the engagement element, in the event that the engagement element rotation is blocked or at least partially blocked for some reason.
- the buffer arrangement comprises an elastic element in the form of spring 175 that is coupled via sliding blocks 167 that slide within groove 191 to and thus rotationally links the motor's axle with the engagement element. Consequently, rotation of the motor initially strains spring 175 and release of this strain, then induces a rotational force on the engagement element causing its rotation.
- the rotation of motor- coupled member 181 bears on one of the blocks 167 (depending on the direction of rotation) via a pin integral with member 181 (not seen and being in a rest state opposite pin 189 that is integral with engaging element 122) to thereby strain the spring that causes the other of blocks 167 to exert rotational force on pin 189 to thereby rotate the engagement element 122.
- Figs. 4 A and 4B also illustrate some other elements of the lock.
- block 137 accommodated within cylinder 104 which can axially rotate within the cylinder.
- Block 137 is rotationally coupled to cam 106 and consequently both jointly rotate.
- Block 137 is coupled at its rear end by means of radial screws 180 to the internal user accessible unit 108 and thus rotation of unit 108 will cause rotation of the cam.
- internal user accessible unit 108 is permanently rotationally coupled to the cam.
- Figs. 4A and 4B Also seen in Figs. 4A and 4B are hard balls 184 that are accommodated within spaces defined in member 162, their function being to inhibit tampering of the lock by axial drilling.
- a pressure-activated lock according to an embodiment of this disclosure will now be described with reference to Figs. 6A-8B.
- Many of the elements in the lock of this embodiment are functionally similar and, at times, structurally identical to elements in the lock of the rotation-activated lock embodiment described above. Accordingly, as already noted above, like elements have been given like reference numerals shifted by a 1000. These like elements will not be described again and description of this embodiment will focus on the unique features in comparison to the rotation-activated lock embodiment.
- the main functional difference as already seen in Figs. 2A and 2B, resides in the user accessible unit 1300 that has the features already described.
- axial rear- ward pressing in the direction of arrow 1320 causes slight displacement of plunger 1130.
- Plunger 1130 has an arresting member 1322 with a rear face 1323 that bears against lever 1128 of micro-switch 1126.
- the rearward displacement of plunger 1130 through pressing on unit 1300 thereby activates the micro-switch which this activates the electronic utility. From here, the operation is similar to that described above: the activation of the electronic utility, lead by activation of micro-switch 1126 causes the electronic utility to send a wireless, typically encrypted signal to the user device, and a response signal from the device, also typically encrypted, then activates the electro-mechanical system and consequently the plunger is released.
- the plunger 1130 has a rear part 1324 with a relatively narrow cross-section and can pass entirely through bore portion 1328. Consequently the plunger can be axially displaced by the bias of spring 1144, a distance defined between the shoulders 1325 of member 1322 and step 1326 at the front end of bore 1328; the forward displacement being arrested when shoulders 1325 engage step 1326. This distance is that required to bring to full extension of unit 1300 from its retracted position seen in Figs. 6A, 7A and 8A, to the extended position seen in Figs. 6B, 7B and 8B.
- portion 1154 which is forward to the plunger shoulders 1148, similar to portion 154 of the rotation-activated lock described above, fits into bore 1158 to thereby rotationally couple unit 1300 with the cam.
- Figs. 8A and 8B are included primarily to show two features: one being pins 1316, already noted above; and the other being for illustration of the structure and function of wings 1306, 1308. Both wings are fitted within a vertical bore with substantially rectangular cross-section and are biased by respective springs 1332, 1334 to deploy into their open state shown in Fig. 8B. When unit 1300 is retracted within bore 1302, these are kept in the closed position, seen in Fig. 8A, by the walls of the bore. Once unit 1300 extends out of the bore, the wings radially deploy into their open state, this radial deployment being limited by means of respective pins 1336, 1338.
- unit 1300 For locking of the pressure-activated lock, unit 1300 needs to be pushed back into to assume its retraced state within bore 1302, after user presses wings 1306, 1308 until their upper end is flush with the external face of unit 1300. Upon such retraction, rear face 1323 of member 1322 engages lever 1128 of micro-switch 1126 to thereby cause the activation of the motor 1116 to rotate the mechanical assembly 1120 in the opposite direction back into the state shown in Figs. 6A, 7A, 8A to thereby lock the lock.
- Fig. 9A The electric and electronic elements of the system to operate the lock, according to the invention, are illustrated in the block diagram of Fig. 9A. These elements are common to both the rotation-activated lock embodiment and the pressure-activated lock embodiment and thus, in order not limit the following description to one of these embodiments a different set of numerals has been used. It should be noted that internal user-accessible unit 108 and 1108 may in fact be identical and hence adapted for functional coupling with the different lock mechanism of the rotation- and pressure- activated lock embodiments.
- These elements include electronic utility 2112 that comprises a micro-switch 2126, processor 2400, transceiver 2500, and motor driver module 2600.
- the electric sub-assembly includes a battery 2114 and an electric motor 2120. Battery 2114 powers both electric motor and the electronic utility.
- the system also includes a user device 3000 with incorporated software utility 3100 that is configured to receive a lock- specific code and transmit a lock-activation code in response thereto via transceiver 3200. Through motor driver module 2600, the electronic utility can induce the motor to operate in either an opening rotation or a locking rotation direction.
- the first step 4000 is one in which the electronic utility 2112 is activated through displacement of micro-switch 2126. This is achieved by turning the external user-accessible unit 102 in the case of the rotation-activated embodiment, or through pressing the external user-accessible unit 1300 of the pressure-activated embodiment. This then, at 4100, causes activation of the electronic utility 2112, which then through the transceiver module 2500 sends at 4200 a first encrypted signal intended to be received by the user device 3000.
- the user device then, at 4300, receives the first signal and the application 3100 running in said device decrypts the data signal and then, at 4400, sends a second, encrypted lock-activation signal to the electronic utility 2112, which is then, at 4500, received by the electronic utility 2112 and decrypted within processor 2400.
- the electronic utility Upon receipt of the properly encrypted second signal the electronic utility, at 4600, activates motor 2120 via motor driver module 2600. This, at 4700, causes the motor to rotate and thereby causing rotation of the engagement element 120,1120 and consequently, at 4800, the plunger is released.
- the external user-accessible unit 102,1300 can be rotated to open the lock.
- the electronic utility typically also includes sensors that are adapted to provide indication on the lock status.
- This may include a sensor, such as sensors 200 and 1200, which may, for example, be X-Y-Z accelerometers that can provide an indication on the status of the engagement element, as well as other elements.
- the application utility 3100 operating in the user device 3000 can also provide the user with an indication of the lock status, and particularly alert the user in the event the lock has not been locked.
