Patent Application
20240312270
The present disclosure relates generally to lock assemblies (locks) for movable closures and the like, and in particular to an intelligent lock that can be actuated in part using a trusted device that is within a selectable proximity of the lock.
Lock assemblies (locks) are generally well-known in the art. Locks are typically flush mounted on an associated closure (such as but not limited to a door closure) to facilitate selectively shifting the closure between an open, unlocked position and a closed, locked position.
It is useful for locks to be accessible and operable at least partially in a keyless, remote manner for convenience and security. However, it is important for remote operation to avoid unauthorized activation and deactivation.
To this end, intelligent remotely activated locks have become more commonly used in the art that allow a user to activate or deactivate the lock using authorized portable items such as key fobs, badges, etc. Such authorized items allow a user to activate or deactivate the lock wirelessly using a device that is near the lock using a simple manual operation (such as pressing a button on the key fob) or by merely locating the item in the lock's range, without further operation required.
However, there is a tradeoff between, on the one hand, reducing the burden on the user of an authorized item to activate or deactivate the lock, and on the other hand, avoiding unintentional activation or deactivation of the lock, or activation or deactivation of the lock using an unauthorized device. Existing remotely activated locks have not been suitably adaptable or configurable to optimize such tradeoffs based on particular user needs or environments.
There is a need for an intelligent lock that can be actuated using one or more trusted portable devices when the trusted portable devices come into a selectable range of the lock.
There is a further need for an intelligent lock that is simple for a user to activate or deactivate while avoiding unintentional activation or deactivation from the user, and while avoiding activation or deactivation using an untrusted device.
There is a further need for an intelligent lock having an operation that is at least partially configurable via the trusted portable devices.
There is a further need for an intelligent lock that can track the one or more trusted devices and/or the locks' locking or unlocking history using such trusted portable devices.
Embodiments provide, among other things, an intelligent lock that senses, using wireless communication (Bluetooth, Bluetooth LE, wireless communication based on or according to protocols such as IEEE 802.11b or more generally IEEE 802.11x (Wi-Fi), etc., or a combination) via a wireless antenna, the presence of one or more trusted interactive portable devices (such as smartphones, tablets, portable computers (such as but not limited to laptops), smart wearables (such as but not limited to smart watches), etc.), referred to herein as trusted devices, that are within a selectable short range or zone of the lock. Trusted devices are devices that have been securely paired to the lock and are associated with the lock, e.g., via a device identifier or ID that is stored in a memory of, or otherwise accessible to, the lock. If the lock is associated with a trusted device, the lock in turn can be considered a trusted lock for that trusted device. A proximity mode can be selected using the trusted device, and in the proximity mode the user can activate or deactivate the lock by interfacing with a portion of the lock, such as by touching a surface of the lock or touching a button on the lock's keypad or touch pad, e.g., providing a one-touch unlock. One or more additional commands can optionally be sent from the trusted device while in proximity of the lock for operating one or more functions of the lock. Locks can be used for and installed in various closures, including but not limited to building doors, vehicle doors, cabinets, portable articles, etc.
The size of the zone within which proximity mode takes place for a particular trusted device (which can be defined, for instance, by wireless signal strength between the lock and the trusted device) can be individually configurable/definable by the user, e.g., by using an application (app) executed by a processor and memory in the trusted device. Each trusted device paired to the lock can thus be associated with a selectable zone boundary around the lock. It will be appreciated that functions may be provided via a single app or multiple apps, and as such the use herein of “app” can refer to single or multiple apps that may be provided on the trusted device for various functions.
In embodiments, this zone can be made more precise by providing a radiofrequency (RF) shield such as a Faraday shield for the wireless antenna of the lock. This can improve wireless communication and the configurability of the zone.
In embodiments, the lock includes an indicator for notifying a user of a trusted device that the trusted device is within the selected zone or range and that the proximity mode is enabled. This lets the user know that the proximity mode commands are available. Example indicators that may be in or on the lock (e.g., on a housing of the lock, or viewable through a housing) include an illuminator such as a light (e.g., a light-emitting diode (LED) or other suitable light, which may be steady or blinking in one or more patterns), audio device (e.g., sound chip or speaker), signal generator (e.g., for sending a notification signal to a specific trusted device).
In embodiments, the user can activate/deactivate a proximity mode for the lock using the app. When the proximity mode has been activated for the lock, and the lock detects that a trusted device is within the defined zone, the lock enables the capability of one or more functions that are set within the app, such as unlocking the lock from a user touching a button or a surface on the lock's keypad or touch pad. In some embodiments, unlocking the lock can be in response to a single action (e.g., touching the lock surface, touching a keypad or touch pad, touching a single icon, pressing a single button, etc.), though multiple command actions may be used in other embodiments. If detection mode is not activated, or if no trusted device is within the defined zone (that is, either no device is within the zone or only devices that are not trusted are within the zone) the lock can disable the functions.
Each trusted device can be assigned a secure ID (e.g., a unique ID not generally known) that is accessible by the lock so that the trusted device is associated with the secure ID by the lock. Secure IDs may be in any form. In embodiments, the secure ID is stored in a suitable memory in the lock.
Embodiments herein further provide systems and methods for operating a lock. The lock can be configured using processor-executable instructions for operating the mechanical elements of the lock and for communicating with one or more trusted devices. The lock can be configured to detect that the trusted device is within a zone (or range, or proximity) of the lock that is configurable, to authenticate the trusted device as authorized, and to, while the trusted device is within the zone of the lock, open the lock at least partly in response to a user of the trusted device interfacing with the lock and/or at least partly in response to a signal from the trusted device, where this signal is in response to the user operating an app on the trusted device.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following figures.
The present disclosure will become more fully understood from the detailed description and the accompanying figures, wherein:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawing and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspects of the invention to the embodiments illustrated.
Referring now to
In the example lock 1, a paddle handle 4 is pivotally mounted in an exterior portion of the housing 2 for rotation between a retracted position and an extended position (
A paddle handle key lock 6 can be mounted on the exterior portion of the paddle handle 4, and may include a movable key lock member 7 that is selectively movable between a locked position and an unlocked position. A paddle handle lock pawl 8 is movably mounted in the paddle handle 4, operably connected with the movable key lock member, and configured such that when the movable key lock member 7 is in the locked position, the paddle handle lock pawl 8 engages a paddle handle recess stop (not shown) in which the paddle handle 4 can be retained in the retracted position. When the movable key lock member 7 is in the unlocked position, the paddle handle lock pawl 8 may assume an unlocked position in which the paddle handle 4 is free to be shifted between the retracted and the extended positions.
A deadbolt key lock 10 may be mounted in the housing 2 for shifting between a locked position, wherein the closure is positively retained in the closed position, and an unlocked position, wherein the closure is free to be shifted between the open and the closed positions. The key lock 6 may be but need not be substantially identical to the deadbolt key lock 10. The deadbolt key lock 10 may include a movable deadbolt key lock member 12, such that the movement of the movable deadbolt key lock member 12 between the locked and unlocked positions contemporaneously shifts the deadbolt key lock 10 between the locked and unlocked positions.
In the example arrangement in
As shown in
The inside surface of the exterior housing plate 22 may include a centrally disposed, horizontally extending plunger slide channel 30 and a horizontally extending deadbolt lock slide channel 32 disposed vertically below the latch plunger slide channel for mounting therein associated portions of the lock, examples of which are illustrated in U.S. Pat. Pub. 2018/0016810. The inside surface of the exterior housing plate 22 can also include a cylindrically shaped lock boss 34, the interior of which defines a lock aperture 27, and a plurality of rearwardly projecting fastener bosses 35 which can facilitate connection of the interior housing plate 23 to the exterior housing plate 22 using fasteners 21. The insider surface of the exterior housing plate 22 also includes a processor such as a microchip or controller 45, explained in more detail below, and a motor 86.
The example interior housing plate 23 includes a marginal portion 40, which engages the interior surface of closure 3, as well as fastener bosses 41, a lock boss 42, and a centrally disposed actuator window 43, and may include a finger recess 44. A rearwardmost or interior side edge 48 of the interior housing plate 23 is contoured inwardly to define a stationary interior handle 49, which facilitates opening and closing the closure 3, e.g., from an interior portion of a vehicle. A release lever 50 can be pivotally mounted on the inner surface of the interior housing plate 23 and extend generally over the finger recess. The example release lever 50 includes a protruding actuator tab 51, which extends through actuator window 43 in the interior housing plate 23 and into an interior pocket in a slide portion 100 of the latch plunger 5 to selectively shift the same to the unlatched position. An interior lock knob 52 can be pivotally received in the lock boss 42 on the interior housing plate 23 and is operably connected with the movable key lock member 12 of the deadbolt key lock 10 to lock and unlock a deadbolt 80.
The interior handle 49 may be formed integrally with interior housing plate 23 along a rearwardmost interior side edge 48 thereof, and may include a central cutaway area 53 for finger access to facilitate shifting closure 3 between the open and closed positions. The example interior handle 49 has a flat portion 54 disposed substantially coplanar with the innermost surfaces of the release lever 50 and the lock knob 52. Furthermore, the interior handle 49 includes a downwardly angled exterior portion 55 in which the cutaway area is formed, and is disposed in an inwardly angled orientation with respect to the flat portion 54. The ramp-shaped exterior portion 55 of the interior handle 49 deflects or leads a pleated or sliding screen over the interior of the lock assembly 1, so as to avoid interference. The finger recess can achieve a low profile, while facilitating grasping and rotating the interior release lever 50.
The interior housing plate 23 can also be provided with a battery compartment 56 disposed between the interior handle 49 and the interior lock knob 52 and release lever 50. The battery compartment 56 is preferably adapted to receive a power source, for instance provided by four AA batteries AA, which are common and easy to install. A battery compartment cover 57 is removably attached to the interior housing plate 23 through tabs 58 that are received within recesses 59 on one edge of the battery compartment and fasteners 62 that secure attachment tabs 63 to the opposite edge of the battery compartment. The batteries in the battery compartment in the interior housing plate 23 are electrically coupled through suitable power lines to provide electrical power to the controller 45 and motor 86 mounted on the exterior housing plate 22.
In the illustrated example, the movable deadlock key lock member 12 of the deadbolt key lock 10 is received in the lock aperture 27 on the exterior housing plate 22, and is rotatably mounted in the lock boss 34 for rotation between locked and unlocked positions. The illustrated lock cam 74, may have a crank arm that is operably connected with the deadbolt key lock 10. The lock cam 74 may further include a cylindrically shaped base with a recessed end oriented toward the exterior housing plate 22, a stop or collar, and a faced shaft oriented toward the interior housing plate 23. A cam actuator 71 can be fitted within the recessed end and is coupled to the distal end of the deadbolt key lock member 12. The recessed end of the lock cam 74 can be provided with opposed lobes on its interior surface. The face of the cam actuator 71 facing the recessed end of the lock cam 74 can be provided with a center edge. This structure allows the rotation of the deadbolt key lock member 12 and the cam actuator 71 within the recessed end to rotate the lock cam 74, but likewise allows the lock cam 74 to rotate to a degree independent of and without the necessity of rotation of the deadbolt key lock member 12 and the cam actuator 71.
A base of the lock cam 74 can be received within the lock boss 34 and engage a recess (not shown) to positively position the lock cam 74 for rotation about its axis only. A lock cam support (not shown) can be provided at the marginal edge of the lock boss 34 to further restrain the lock cam 74 from extraneous motion. The faced shaft on the lock cam 74 extends through the lock boss 42 in the interior housing plate 23, and engages the lock knob 52 mounted on the interior end thereof, such that rotation of the lock knob 52 from the interior of the closure rotates the lock cam 74 between the locked and unlocked positions to shift the deadbolt 80 between the locked and unlocked positions, as described below.
The illustrated deadbolt key lock 10 and the lock knob 52 can be operably connected with the deadbolt 80 slidably mounted in a deadbolt lock slide channel of the exterior housing plate 22, which can include an outer end that extends exterior of the housing 2 for engagement with door strike 15, and an inner end 82, which extends interior of housing 2. A first link 83 has a first end thereof pivotally connected with an orifice provided at the inner end of deadbolt 80, and a second end thereof pivotally connected with a first orifice in a motor crank arm 76, which is, in turn, operably connected to a motor shaft extending from the motor 86 mounted to the exterior housing plate 22.
A second link 87 has a first end thereof pivotally connected with a second orifice in the motor crank arm 76 and a second end thereof pivotally connected to an orifice 73 of the crank arm of the lock cam 74, such that rotation of the motor shaft rotates the motor crank arm 76 between the locked and unlocked positions and simultaneously longitudinally shifts the deadbolt 80 between the locked and unlocked positions. Preferably, the first link 83 and the second link 87 are identical in length, height, gage, and material so as to be interchangeable, avoiding assembly error. An example motor 86 is a 6 vdc motor capable of 320-340 RPM at 6 vdc with a gear reduction of 100:1, which, due to the geometry of the linkages and along with the fact that with two separate linkages the motor 86 need only rotate 90 degrees or less, preferably less than about 80 degrees, and provides high-speed actuation capable of activating deadbolt 80 in approximately ¼ second. Alternative configurations for the lock are disclosed in U.S. Pat. Pub. 2018/0016810.
The motor 86 can be mounted in a recess pocket 92 integrally molded into the interior side of the exterior housing plate 22. The pocket 92 may be designed to prevent water pooling proximate the motor 86. The pocket 92 may securely contain the motor 86 from misalignment and provides ease of assembly because the motor 86 is simply slid into the pocket 92. An interconnect board 69, into which the battery power line 46 is connected via a plug, provides power to the touch pad 36 and the motor 86 via wires 108 routed through wire channel 109. The interconnect board 69 may also contain one or more micro switches 105, discussed below, for indicating the locked and unlocked deadbolt 80 positions. Preferably, the interior surface of the exterior housing plate 22 incorporates a pocket for ease of location and installation of interconnect board 69.
In the illustrated lock assembly 1, an interior backer plate 120 is disposed between the exterior and interior housing plates 22 and 23, covers the interior faces of deadbolt 80 and slide portion 100, and is attached to fastener bosses 121 on the interior side of the exterior housing plate 22 to retain the moving components securely in place.
The axis of rotation of the motor crank arm 76 may be fixed by a combination of a pocket 92, discussed above, as well as a circular pad on the motor crank arm 76 and an orifice 94 in the interior backing plate 120 that holds the motor 86 in place. These features prevent the motor crank arm 76 from moving laterally, and yet allow the motor crank arm 76 to freely rotate. Preferably, the interior surface of the exterior housing plate 22 includes physical stops 96, 97 to prevent the motor crank arm 76 from over rotation and to prevent the deadbolt 80 from being forced to the unlocked position.
The example latch plunger 5 includes a slide portion 100 which is slidably mounted in the latch plunger slide channel 30 on the inside surface of the exterior housing plate 22 for laterally shifting between latched and unlatched positions. Slide portion 100 has an exterior pocket 101 into which an actuator tab 26 on paddle handle 4 is received, such that shifting paddle handle 4, e.g., from the exterior of a vehicle, between the retracted and extended positions longitudinally shifts slide portion 100 in a lateral direction between a latched position and an unlatched position. The slide portion 100 has an interior pocket 47 into which an actuator tab on a release lever is received, such that shifting the release lever 50 from the interior of the closure similarly shifts slide portion 100 between the latched and unlatched positions. A coil spring 102 is mounted in the latch plunger slide channel 30 and is abuttingly received in a centering hole in a rearward side edge 103 of slide portion 100 to urge the slide portion 100 toward the normally latched position.
In an example operation, the closure 3 can be shifted from the closed to the open position from the exterior of the vehicle (for instance) in the following manner. With the paddle handle 4 in the unlocked position via a key 126 and the deadbolt key lock 10 in the unlocked position, the paddle handle 4 may be rotated outwardly from the retracted position to the extended position. Rotation of the paddle handle 4 from the retracted position to the extended position pivots the actuator tab 26 laterally, which, in turn, moves the slide portion 100 laterally inwardly. The lateral inward shifting of the slide portion 100 causes the latch plunger 5 to shift to the unlatched position. The latch plunger 5 thereby disengages from the door strike recess 16, and permits the user to shift closure 3 from the closed position to the open position, as shown in
Closure 3 can be similarly shifted from the closed position to the open position from the interior of the closure in the following manner. With the paddle handle 4 in either of the locked or unlocked positions and the deadbolt key lock 10 in the unlocked position, the release lever 50 may be rotated laterally inwardly from the retracted position to the extended position, which pivots the actuator tab 51 laterally, and moves the slide portion 100 inwardly. The inward shifting of the slide portion 100 also causes the latch plunger 5 to shift to the unlatched position. The latch plunger 5 thereby disengages from the door strike recess 16, and permits the user to shift closure 3 from the closed position to the open position.
In order to return the closure 3 to the closed and latched position from either the exterior or interior of the closure, the user can simply shift the closure 3 to the closed position, which causes an inclined surface on the latch plunger 5 to strike the door strike 15 and thereby push the latch plunger 5 into the interior of the lock 1. When the latch plunger 5 comes into registry with the door strike recess 16, the latch plunger 5 is urged back to the latched position by virtue of the spring biasing force exerted by coil spring 102, thereby preventing the door from being inadvertently shifted from the closed position to the open position. The latch plunger 5 may also have a slightly inclined surface relative its longitudinal length to provide a greater resistance to inadvertent opening of the closure 3 and more reliable engagement with the door strike recess 16, particularly when the lock assembly 1 is applied to a trailer or other mobile application subject to significant vibrations during transit.
When the closure 3 is in the fully closed and latched position, the same can be positively locked in place by rotation of deadbolt key lock member 12 or interior lock knob 52. A matching deadbolt key 128 may be inserted into the key slot 129 in the deadbolt key lock member 12, and the same are then rotated from the unlocked position to the locked position. Rotation of the deadbolt key lock member 12 rotates the lock cam 74, which, in turn, contemporaneously shifts the crank arm of the lock cam 74, the second link 87 pivotally connected with the motor crank arm 76, the motor crank arm 76, the first link 83 pivotally connected with the motor crank arm 76 and the inner end of deadbolt 80, and deadbolt 80 from the unlocked to the locked position. In the locked position, the deadbolt 80 engages the door strike recess 17 in the door strike 15, and positively prevents opening of the door. The deadbolt key lock 10 can be unlocked by rotating the deadbolt key 128 and the associated deadbolt key lock member 12 in the opposite direction. The deadbolt 80 can be similarly shifted between the locked and unlocked positions from the interior of the closure 3 by rotation of the interior lock knob 52.
The closure 3 can also be positively locked in place by actuation of touch pad 36. For instance, a numerical code may be programmed on the microchip or controller 45 at the time of manufacture of the lock assembly 1. The original code may be, as a nonlimiting example, a null-code, such as “1111.” After purchase by the end-user, the code can be modified and customized to the end-user's preference. Preferably, the code may be repeatedly changed as deemed appropriate by the end-user. Once the predetermined numerical code is entered into the buttons 37 of the touch pad 36, the controller 45 can receive a signal that the closure 3 is to be placed in the locked mode. The controller 45 can then open a switch to send electrical power to actuate the lock motor 86. Preferably, the rotation of the motor 86 is about 90 degrees or less, and more preferably less than 80 degrees, in either direction. Upon actuation of the lock motor 86, the lock motor 86 rotates the motor crank arm 76, e.g., clockwise, which shifts the first link 83 pivotally connected with the motor crank arm 76 and the inner end of deadbolt 80, and deadbolt 80 from the unlocked to the locked position. In the locked position, deadbolt 80 can engage the door strike recess 17 in the door strike 15, and positively prevent opening of the door. The crank arm 75 of the lock cam 74 and the second link 87, pivotally connected with the motor crank arm 76, are also placed in the locked position. The deadbolt 80 is unlocked by re-entry of the predetermined numerical code and subsequent rotation of the lock motor 86 counterclockwise.
As shown in
In the event of an electrical problem with the lock assembly 1, it is contemplated that the deadbolt 80 can still be activated by the deadbolt key 128 or internal lock knob 52. That is, the deadbolt 80 can be similarly shifted between the locked and unlocked positions from the interior of the closure by rotation of interior lock knob 52 and from the exterior of the closure by rotation of the deadbolt key lock member 12.
In the preferred example, a computer input device in the form of a flat panel or surface divided into several, differently marked, touch-sensitive areas form a relatively large, illuminated touch pad 36 including buttons 37. An example touch pad 36 may be provided by HSS Touch Technology and developed by AlSentis® HSS™, which is capable of identifying when a surface touch occurs without using pre-determined capacitive thresholds. However, other capacitive touch technologies and mechanical buttons can be employed as the buttons 37 of the touch pad 36. In an example lock 1, the buttons 37 have a diameter of at least ½ inch, with black numerical indicia 38 against a white background. Other indicia can be used, such as letters and symbols. A sensor 64 is disposed on the controller 45 and extends to the external surface of the exterior housing plate 22 for determining the proximity of a hand of a user. Illuminators that illuminate the buttons 37 of the touch pad 36, such as but not limited to LEDs, are disposed beneath the buttons 37, which may be translucent.
Upon detection of the user's hand or other appendage or contact source, the controller 45 can activate the LEDs to backlight the numerical indicia 38 to facilitate entry of the code. Alternatively or additionally, the controller 45 may process the detected touch to perform other functions, such as for a one-touch unlocking operation as described in more detail below. After a predetermined period of non-use, the LEDs may be deactivated to conserve battery power. Alternatively or additionally, the illuminators may be actuated by touch or depression of any of the buttons 37, as is readily available using the example HSS Touch Technology.
Audible feedback may be provided to successfully indicate locking and unlocking functions. For example, audible features may also be used to: signal that the assembly is ready to accept new code by emitting three short beeps; signal that a new code is entered by emitting four short beeps; signal that an incorrect code was entered with one long beep; signal that the deadbolt 80 is locked or unlocked with two short beeps; signal that the deadbolt 80 failed to lock or unlock with one long beep; and signal low battery charge with one long beep after the lock/unlock beeps. The controller 45 may be programmed such that the assembly will cycle up to ten (or other number) more times once the low battery indication occurs. After this, the final electric function in a low battery condition preferably implements a protocol to prevent the electronic locking function.
The lock assembly 1 described herein may be adapted for operable connection with a remotely operated signaling device such as but not limited to a key fob (not shown) or another trusted device such as device 320, described in more detail below. In example operation, the controller 45 may be programmed to interface with a built-in receiver, e.g., a wireless receiver, to receive a signal from a remotely operated signaling device equipped with a transmitter to place the lock assembly 1 in the locked mode. In response to such a signal, the controller 45 then opens a switch to send electrical power to actuate the lock motor 86. Upon actuation of the lock motor 86, the lock motor 86 rotates the motor crank arm 76 clockwise, which shifts the first link 83 pivotally connected with motor crank arm 76 and the inner end 82 of deadbolt 80, and deadbolt 80 from the unlocked to the locked positions. The closure 3 may be unlocked in similar fashion.
The controller 45 can be programmed at the time of manufacture of the lock 1 or afterward (e.g., in the field) using processor-executable instructions that can be stored in or otherwise accessible to the controller to perform example methods herein, including but not limited to controlling an input device for the lock 1 for actuating or deactivating the lock to lock the closure 3 (e.g., opening a switch to send electrical power to actuate a lock motor 86, actuating a deadbolt 80), monitoring for trusted devices, authorizing trusted devices, actuating one or more indicators (such as LED 300), monitoring the state of battery or other power source charge, and interacting with the trusted devices according to example methods.

A radiofrequency shield (
As shown in
The signal attenuation provided by the Faraday shield 304 and the attenuator 330 in combination can help avoid an unintentional recognition by the lock 1 that a trusted portable device is in the selected proximity. By providing this signal attenuation, the trusted device can be more deliberately positioned in proximity to the lock 1 (e.g., by a user approaching the lock while the trusted device is carried in the user's hand, clothing (e.g., pocket), bag, purse, etc.), and in response the lock 1 can signal, e.g., via the indicator 300 that the lock recognizes the trusted device so that the user can deactivate the lock easily, such as by touching the touch pad 36, keypad 37, or button on the lock.
Referring to
The remote portable device 320 can be embodied in, for instance, a smartphone as shown in
The remote portable device 320 is preferably associated with, e.g., assigned, embedded with, etc., a device identifier (ID) that is stored in a memory of, or otherwise accessible to, the controller 45 so that the remote portable device is considered a trusted device by the lock. The device ID is preferably unique to each remote portable device 320, or at least each trusted device. The lock 1 may itself be associated with a unique ID (a Lock ID) that in turn can be associated with the device IDs of trusted devices, and accordingly may be considered a trusted lock for a particular trusted device. This association may be stored in the controller 45, in a remote storage, in a central storage, in the remote portable device 320, or elsewhere, in any combination. Individual locks 1 may be associated with multiple remote portable devices 320 providing trusted devices, and individual remote portable devices may be associated with multiple locks providing trusted locks.
The device ID may be created in any suitable manner (random, hashed, selected, etc.) and assigned by a user or by a central entity, for instance. In other examples, the device ID may be a unique ID already associated with computing or networking devices (such as a MAC address, Unique Device ID (UDID), IMEI, IMSI, etc.). Reference herein to a stored device ID is intended to refer to device IDs that are either stored in the controller 45 itself or that otherwise are accessible to the controller during operation. The stored ID can be provided to the controller 45, for instance, at the factory, provided during installation, and/or provided after installation such as by a central computing unit that updates stored IDs, by the remote portable device 320, or by another device that interfaces with the controller. Stored IDs can be stored as data via one or more tables, by hard coding, or by any other suitable format.
A remote portable device 320 that is trusted by the lock 1 for performing locking or unlocking operations, e.g., by having a device ID that is known to the controller 45 to be authorized for controlling the lock 1, or at least activating or deactivating the lock, is referred to herein as a trusted device or alternatively a securely paired device. This pairing may be distinct from, for instance, more general pairing for communication methods or protocols such as Bluetooth or Bluetooth LE pairing in devices such as earbuds, appliances, etc. (e.g., where a device in a vicinity may pair) in that a device ID for the remote portable device 320 is registered with the lock 1 to provide a trusted device, though both standard Bluetooth or Bluetooth LE pairing (or pairing via other communication such as wireless protocols such as IEEE 802.11b or more generally IEEE 802.11x (Wi-Fi), or a combination) and device ID association can be required or used. It is also possible that the device ID used for standard communication pairing and device ID association is the same ID, while in other embodiments, these IDs are distinct. In a nonlimiting example pairing operation, a personal code may be entered on the keypad 37 of the lock 1 followed by an additional input (e.g., touching two or more buttons, a submit or enter command, etc.). This puts the lock 1 in pairing mode and prevents unsecured devices from being paired. Preferably, the pairing also is encrypted.
It is possible that remote portable devices 320 can have different trust levels associated with a device ID. For instance, some trusted devices may be permitted to activate and deactivate the lock and set various functions related thereto but may not be able to add or remove device IDs or receive or transmit history data or a subset of the same, while other trusted devices may be permitted to do so. In some example embodiments, the controller 45 stores each remote portable device's unique ID to track trusted devices.
If the user does not enable proximity mode at 906, the lock 1 optionally may be operated with one or more interfaces at 908 such as Bluetooth, 802.11x (Wi-Fi), and/or other wireless communication-based operation, touch pad operation, or using a key, such as described above. On the other hand, if the user enables proximity mode at 906, e.g., using the selector on example settings screen 1000, the app screen allows a user to configure or adjust the proximity mode at 908, e.g., to set an activation distance by displaying a tool such as a slider as shown in configuration screens 1100, 1200. Configuring or adjusting the proximity mode at 908 can include adjusting a close field boundary in which a Device will detect the presence of a securely paired (or trusted) device. “Close field” as referred to herein is a defined area (e.g., by the user via the app) in which the lock 1 can sense or detect the presence of a remote portable device 320 that was securely paired to the lock. In this way, the lock 1 can differentiate non-paired and paired phones within the defined close field area. Typically, for a communications method such as Bluetooth, Bluetooth LE, 802.11x, etc., or a combination the maximum range or area would be determined by the remote portable device's and the lock's Bluetooth and/or Wi-Fi modules, including antennae capability and specifications.
In embodiments, the proximity mode is configured or adjusted by configuring an activation distance in the app. This activation distance is typically set by signal strength between the portable device 320 and the lock 1 (e.g., their respective antennas). For instance, the screens 1100, 1200 in
In this way, the zone within which the lock allows a particular trusted device (which zone can be defined, for instance, by signal strength between the lock and the trusted device) to be used in a proximity mode is individually configurable/definable by the user, e.g., by using an application (app) executed by a processor and memory in the trusted device. In embodiments, each trusted device can define its own close field boundary, and each trusted device paired to the lock can thus be associated with a selectable zone boundary around the lock. During operation, the device 320 would not be recognized for proximity mode operation outside the limits of the set zone.
The lock 1 can then be operated, e.g., activated and deactivated, using the enabled proximity mode at 912, which mode may be in addition to (as shown) or an alternative to other unlocking modes, such as Bluetooth (shown in
An example monitoring and locking/unlocking method 1300 performed by the trusted device 320 via the app is shown in
If the connection succeeds, the app determines at 1314 whether proximity mode has been enabled. Proximity mode can be enabled once the trusted device 320 wirelessly connects to the lock 1. If proximity mode is not enabled, the app waits for user input at 1316. If a lock/unlock command is received, e.g., the user presses a lock/unlock button such as via the app, the lock/unlock command is sent to the lock at 1318, and the app then returns to wait for user input at 1316. If the connection fails during this time, the trusted device 320 returns to scanning for trusted locks at 1310.
If proximity mode is enabled at 1314, the app measures at 1320 the signal strength of a wireless signal received from the lock 1, e.g., using signals generated from the transceiver provided on the portable device 320. If the measured signal strength is greater than (or in some embodiments, greater than or equal to) a user setting providing (or processed to provide) a threshold for the activation distance, it is determined at 1322 that the trusted device 320 is within the selected close field of the lock 1. A proximity active command is then sent to the lock 1 at 1324. An example proximity active command is a secure message sent to the lock 1 indicating that proximity mode has been activated. In this way, when a trusted device 320 (i.e., a paired remote portable device having an ID that is associated with one stored in the lock) comes in the defined close field boundary, a secure message can be sent to the lock 1 indicating that the particular trusted device is inside the close field boundary. Proximity mode is activated in response, and the lock 1 can activate the indicator 300, e.g., illuminating the LED, causing the LED to blink, etc.
The presence of the trusted device 320 can then be used by the lock 1 while in the proximity mode to enable or disable certain functions. For example, once the trusted device 320 is detected inside the close field, the lock 1 can unlock with a simple user action, such as the simple press of a button or a surface on the lock's keypad 37 or touch pad 36, e.g., a one-touch unlock, or an icon (soft button).
Returning to
A signal measurement timeout timer is then started at 1328, and after a waiting period at 1330 for a time (which may be selectable or fixed), the timer expires, and signal strength is again measured at 1320 to determine whether the trusted device is still within the close field. If connection fails while the measurement timeout timer is running at 1330, the trusted device again returns to scanning for trusted locks at 1310.
Referring now to
If the received command is a lock/unlock command outside of proximity mode, the lock 1 performs the requested command at 1414, and waits for additional commands from the app at 1412. If the app connection fails, the lock returns to waiting for the app to connect at 1410.
If the lock 1 receives an activate proximity command, the controller 45 can also activate the indicator 300 (e.g., switches on the LED, which can blink or remain steady) to signal to the user and/or the trusted device 320 that the lock can now receive proximity mode commands such as but not limited to a one-touch locking/unlocking command. The lock 1 enables proximity unlock/locking commands at 1416, such as but not limited to a lock or unlock command issued by touching the keypad (touch pad) 36, buttons 37, etc. The example indicator 300 allows the user to set or receive feedback regarding the proximity mode distance for their particular device 320. It provides a visual representation for the distance and allows the user to know the lock 1 is locked and can be unlocked by, e.g., touching a button on the keypad 37 or touching the touch pad 36.
Having enabled proximity unlock at 1416, the lock 1 starts a proximity timeout timer at 1418 and waits for additional commands at 1420. While the proximity timeout timer is running, if a locking or unlocking command such as via a touch input signal (e.g., a single touch input, an enter button, etc.) is received by the lock 1, the lock deactivates or activates the lock accordingly at 1422, and waits for further commands at 1420. If a new activate proximity command is received from the trusted device 320, the proximity timer is restarted at 1418. However, if the proximity timer expires, and no appropriate proximity mode command is received, the lock 1 can disable proximity unlock mode at 1424, deactivate the indicator 300 (e.g., switch off the LED), and wait for further commands from the app at 1412. In this way, the lock 1 detects when the trusted device 320 has left the left the close field boundary or otherwise lost communications, and disables proximity functions inside the lock. If, during the waiting time, the trusted device (e.g., app) connection fails, the proximity unlock mode is also disabled at 1426, the indicator 300 can be deactivated, and the lock 1 can again wait for a connection from a trusted device 320 at 1410.
The trusted device 320 and/or the lock 1 may store in their memory data corresponding to one or more aspects of locking/unlocking history or status for one or more locks and/or devices.
The locking and unlocking history for one or more trusted devices 320 (e.g., by device ID) and/or locks 1 (e.g., by lock ID) can be stored, in any combination, in trusted devices, locks, remote or central processing locations, or any combination. Other data that may be stored and associated with locks and/or trusted device include, but are not limited to, battery status of locks; connection time by device ID, proximity activated time by device ID, number of dropped/failed connections; unauthorized locking/unlocking attempts; and others.
