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.

  • the lock will open only upon receipt of the proper (typically encrypted) lock opening code from the user device.

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.

  • 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.

  • 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.

  • 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.
