Description

Technical Field

[0001] This invention relates to lock assemblies for windows and doors. Specifically, this invention relates to a lock assembly including an automatic mechanism for extending at least one latch and an electronic method for retracting the latch. Background Technology

[0002] Electronically controllable lock components are known and used to secure doors or windows. These components use an electric actuator to extend and retract a locking latch, thereby locking and unlocking the window or door. Some electronically controllable lock components also include an authentication authority that verifies the user's identity, for example, by using biometric data such as fingerprint sensors, voice recognition, and / or facial recognition. Once the authentication system has verified the user's identity, the electric actuator of the lock component is configured to disengage the locked latch, allowing the user to open the door or window.

[0003] Recently, locking mechanisms have been developed that use mechanical triggers to automatically extend the locked latch when a window or door is closed. Examples of such locking mechanisms are described in the applicant's GB patent applications GB2584100 and GB2564225.

[0004] Powering electronically controlled lock components can be challenging. Some electronically controlled lock components use batteries, but these require periodic battery replacements due to their relatively high energy demands. Other electronically controlled lock components connect directly to the main power source, but wired connections to the lock components are difficult to implement in moving door panels and can also introduce security vulnerabilities.

[0005] This invention attempts to solve or improve one or more problems of lock components for doors and windows, or to provide useful alternatives. Summary of the Invention

[0006] According to a first aspect of the invention, a lock assembly is provided. The lock assembly may include a locking mechanism. The locking mechanism may include at least one latch. The lock mechanism may include an automatic actuation mechanism. The automatic actuation mechanism may include a trigger configured to trigger at least one latch when the trigger is actuated. The lock assembly may include a handle assembly. The handle assembly may include a spindle connectable to the handle. The spindle may be connected to the lock mechanism such that rotation of the spindle retracts at least one latch. The handle assembly may include a spindle locking mechanism configured to prevent rotation of the spindle when engaged. The lock assembly may include an electronic mechanism for engaging and / or disengaging the spindle locking mechanism.

[0007] The trigger can be mechanical. The trigger can be non-electronic. The trigger can be non-magnetic. The trigger can be compressible or depressable. Triggering at least one latch can include extending at least one latch. A spindle can be coupled to and / or integrally formed with a handle. At least one latch can be selectively movable between an extended position and a retracted position. At least one latch can be a fixed latch.

[0008] Advantageously, the use of an automatic actuation mechanism reduces the amount of electrical energy required to operate the locking mechanism and thus the locking components. Specifically, using an electronic mechanism to disengage the spindle locking mechanism, rather than retracting or extending at least one latch, reduces the electrical energy required to operate the locking components. By reducing energy demand, the system's battery life is significantly improved.

[0009] The electronic mechanism may include an authentication unit for verifying user identity. The authentication unit may include at least one of the following: a biometric sensor; a receiver; and / or a keyboard. The biometric sensor may include a fingerprint sensor and / or a camera. The camera may be configured for facial and / or iris recognition. The biometric sensor may include, for example, a microphone for voice recognition. The receiver may include a radio wave receiver, a radio frequency identification (RFID) receiver, a Bluetooth receiver, a Bluetooth Low Energy (BLE) receiver, and / or a Wi-Fi receiver. The keyboard may be electronic. The keyboard may include a series of keys, buttons, and / or a touchscreen.

[0010] The authentication unit can be configured to receive input from a user. Input may include biometric information (e.g., fingerprint). Biometric information can be automatically acquired, for example, via a camera or RFID system, when the user moves within a predetermined distance of the authentication unit. Optionally, input may include a username, code, and / or password. Input may include wireless signals, such as those transmitted from a user equipment (UE). The UE may include a mobile phone, computer, tablet, keychain, or any other similar electronic device. The UE can be configured to send a signal to a receiver when the user performs an action. This action may include the user opening application software. This action may include the user entering information into the application software. This action may include the user connecting to Wi-Fi. This action may include the user connecting to a local area network (LAN). This action may include the user bringing the UE within a predetermined distance of the authentication unit.

[0011] The authentication unit may also include a memory. Optionally, the memory can be remotely stored and connected to the authentication unit via a wired or wireless interface. The memory can be configured to store user authentication information. The stored user authentication information can be used to verify the user's identity. The stored user authentication information may include the user's biometric data, username, password, and / or code.

[0012] User identity can be verified by comparing the received input with stored user authentication information. Successful user authentication is indicated by detecting a match between the received input and the stored user authentication information.

[0013] Authentication units may require multi-factor authentication to verify user identity. For example, an authentication unit may require the user to enter two or more of the following: biometric data, username, password, and / or code, to successfully verify user identity. Advantageously, using multi-factor authentication improves the security of lock components.

[0014] The electronic mechanism can be configured to disengage the spindle locking mechanism upon receiving a signal from the authentication unit indicating successful user authentication.

[0015] The spindle locking mechanism may include a limiter portion configured to engage with the spindle and prevent rotation of the spindle. The locking assembly may also include a biasing device configured to bias the limiter portion to an engaged position (e.g., where the limiter portion engages with the spindle). The biasing device may be a spring. Additionally or alternatively, the limiter portion may be configured to move to the engaged position under the influence of gravity.

[0016] The electronic mechanism may also include an electric drive. The electric drive can be configured to move the limiter portion to a disengaged position. The disengaged position may be a position where the spindle is rotatable. Alternatively, the electric drive can move the limiter portion to an engaged position.

[0017] Advantageously, using a biasing device and / or gravity to bias the limiter portion to the engaged position ensures that the limiter will return to the engaged position even if the electronic mechanism and / or electric drive fails.

[0018] In a range of embodiments, the electric drive may include a motor. The electric drive may include a power source, such as a battery or battery pack. The battery or battery pack may be located within the handle assembly.

[0019] The electric drive unit may include a power transmission mechanism for connecting a motor to a limiter portion. The power transmission mechanism may include an insert linkage mechanism (fork yoke). The limiter portion may include a slot or channel. The power transmission mechanism may include at least one gear, which includes a drive pin that can be received within the slot or channel. The insert linkage mechanism may be configured such that rotation of at least one gear drives linear movement of the limiter portion. For example, the drive pin may apply a driving force to the side or wall of the slot or channel, thereby driving linear movement of the limiter portion.

[0020] The power transmission mechanism may include one or more gears. Multiple gears may include bevel gears and additional gears connected to the bevel gears. The additional gears may include a drive pin connected to the additional gear.

[0021] In some embodiments, the electric drive may include a servo motor or a linear actuator.

[0022] In some embodiments, the mandrel may include a rotor coupled to the mandrel. The rotor may be configured to rotate with the mandrel, for example, to prevent relative rotation of the rotor on the mandrel.

[0023] The rotor and limiter portions may include an interlocking structure. When the limiter portion engages with the rotor and / or spindle (e.g., when the interlocking structure is engaged), the interlocking structure prevents rotation of the rotor relative to the limiter portion. The interlocking structure may include teeth and recesses. Teeth may be provided on the limiter portion, and recesses may be provided on the rotor, and vice versa. Alternatively, the interlocking structure may include multiple teeth and multiple recesses.

[0024] The lock assembly may also include a direction sensor. The direction sensor can be configured to determine the orientation of the spindle. The direction sensor may include a magnet coupled to the spindle. The direction sensor may include a magnetic field sensor (e.g., a Hall sensor or reed switch). The Hall sensor or reed switch can be configured to determine the position of the magnet. By detecting the position of the magnet, the Hall sensor or reed switch can be configured to determine the orientation of the spindle, thereby determining whether the spindle is rotating.

[0025] The electronic mechanism can be configured to prevent the spindle locking mechanism from engaging when the orientation sensor determines that the spindle is misaligned with the spindle locking mechanism. The spindle may be misaligned with the spindle locking mechanism when it has already rotated relative to the limiter. The spindle may also be misaligned when it rotates away from its rest position. The rest position can be defined as a position where no torque is applied to the spindle.

[0026] Advantageously, by preventing the spindle locking mechanism from engaging when the orientation sensor determines that the spindle and the spindle locking mechanism are not aligned, the electronic mechanism can prevent damage to the spindle locking mechanism.

[0027] The electronic mechanism can be configured to automatically engage the spindle locking mechanism after a predetermined time interval. This predetermined time interval can be the time required for the user to rotate the spindle, retracting at least one latch, and for the spindle to return to its original position. The predetermined time interval can be adjusted by the user, for example, according to their preference. By automatically engaging the spindle locking mechanism after the predetermined time interval, the door equipped with this component will automatically lock, preventing the spindle locking mechanism from remaining in a disengaged state indefinitely.

[0028] The automatic actuation mechanism may include a drive plate. The drive plate is operatively connected to a trigger. The drive plate is operatively connected to at least one latch. The drive plate may be configured such that triggering at least one latch includes lowering the drive plate under the action of gravity or a biasing mechanism, thereby driving the latch to an extended position.

[0029] Actuation of the trigger (e.g., compression or depressing) can move the drive plate. The drive plate can be operably connected to at least one latch via a linkage mechanism. The linkage mechanism can include at least one link. The linkage mechanism can be configured to convert the motion of the drive plate under the action of gravity or a biasing mechanism into the motion of at least one latch. The motion of at least one latch can be perpendicular to the motion of the drive plate, and / or the motion of at least one latch can be a rotational motion. The locking mechanism can be configured such that rotation of the spindle causes the drive plate to rise. The trigger can hold the drive plate in the raised position before it is actuated (e.g., before the trigger is compressed or depressed).

[0030] The locking mechanism may also include a key-operable lock cylinder. The locking mechanism and lock cylinder may be configured such that the operable lock cylinder extends and / or retracts at least one latch.

[0031] Advantageously, using a lock cylinder to extend and / or retract at least one latch provides an alternative mechanism for operating the lock mechanism in the event of a failure of the automatic actuation mechanism or spindle locking mechanism, a power failure of the electronic mechanism, or a dead battery.

[0032] In a series of embodiments, the mandrel may include a fragile portion. The fragile portion may be configured to break when a force greater than a predetermined value is applied. The fragile portion may include at least one groove or at least one notch in the mandrel. The groove or notch may be perpendicular to the length axis of the mandrel. The fragile portion may be positioned such that, in the event of breakage, a portion of the mandrel remains within the handle assembly and connected to the locking mechanism and the mandrel locking mechanism. Advantageously, the fragile portion ensures that excessive forces (e.g., forces from an attacker attempting to force the mechanism apart) are not transmitted to the mandrel locking mechanism and damage it.

[0033] The locking mechanism may also include a housing. The locking mechanism may include a mandrel bore positioned within the housing and configured to receive a mandrel passing through it. A fragile portion may be positioned such that, in the event of breakage of the fragile portion, the mandrel will not extend beyond the mandrel bore. The housing may include a gearbox. A trigger may be attached to or disposed on the housing. Additionally or alternatively, the fragile portion may be positioned such that, in the event of breakage of the fragile portion, one end of the mandrel is flush with a surface of the housing.

[0034] The locking assembly may also include a stop. The stop may be configured to restrict the removal of the spindle. The stop may include a protrusion (e.g., a pin) extending from the spindle. The stop may be configured to prevent the spindle from being removed in a first linear direction (e.g., along the longitudinal axis of the spindle itself). The protrusion may be larger than the size of the spindle bore, thereby preventing the spindle from being pulled past the spindle bore.

[0035] Additionally or alternatively, the stop device may include a blocking portion in the handle assembly. The blocking portion may include a plate (e.g., a reinforcing plate). The blocking portion may be configured to prevent the mandrel from being removed in a second linear direction opposite to the first direction (i.e., along the longitudinal axis of the mandrel). The blocking portion may abut against an end of the mandrel to prevent the mandrel from being pushed through the mandrel bore in the second linear direction.

[0036] The locking mechanism may also include at least one remote locking unit, which includes other latches and a drive rod operably connected to an automatic actuation mechanism.

[0037] In a second aspect of the invention, a door or window assembly is provided that includes the locking assembly as described above. The door or window assembly may include a frame and a door or window sash. The locking assembly may be located in or on the door or window sash, for example, on or within the front end surface of the door or window sash. The door or window assembly may include at least one retainer located in or on the frame for engaging the locking assembly with a locking latch.

[0038] The locking assembly can be configured such that a trigger is actuated when the door or window sash is aligned with the frame during a closing operation of the door or window assembly. The trigger can be actuated by a retainer. The door or window can be aligned with the frame when the door or window sash is closed and / or when a latch is aligned with at least one retainer. Actuating at least one latch can include extending at least one latch into a retainer. Retracting at least one latch can involve retracting at least one latch from the retainer.

[0039] It should be understood that any one or more features from any aspect of the present invention may be combined with other features from any aspect of the present invention. Attached Figure Description

[0051] It will be understood that the use of terms such as up, down, left, right, clockwise, and counterclockwise is for descriptive purposes only to aid understanding, and therefore does not exclude alternative directions or configurations of the disclosed invention.

[0052] Turn now Figure 1 The diagram shows a perspective view of a lock assembly 500. The lock assembly 500 includes a lock mechanism 1 and a handle assembly. The handle assembly includes a first handle 100 and a second handle 200. The first handle 100, the lock mechanism 1, and the second handle 200 are connected by a spindle (not shown) extending through a spindle hole 16. The first handle 100 can be attached to the inside of a door or window sash (not shown). The second handle has a conventional lever handle 202 connected to the spindle. The second handle can be attached to the outside of the door or window sash. The lock mechanism 1 has a cover plate 3 and is recessed into the edge of the door or window sash. In use, rotation of the lever handle 202 and the connected spindle is configured to retract the latch 4.

[0053] Turn now Figure 2The image shows a partially exploded front perspective view of a first handle 100. The first handle 100 includes a pull handle 52 attached to a first handle body 62 by a first screw 51a and a second screw 51b. The pull handle 52 has two battery holders 54a and 54b configured to receive a conventional battery / battery pack (not shown) (such as AA batteries). The pull handle 52 also includes a battery cover 50 configured to cover the battery holders 54a and 54b. The first handle body 62 has a keyhole 14 for receiving a cylinder lock (not shown). The first handle body 62 also houses an electronic mechanism having a printed circuit board (PCB) 57 including a microprocessor 58. As will be described below, the electronic mechanism is also connected to other electrical components. In use, the microprocessor 58 and the PCB 57 are covered by a snap-fit ​​plate 56.

[0054] The first handle 100 also includes a spindle stop device 60 having a reinforcing plate connected to the first handle body 62 by mechanical fasteners. In use, the reinforcing plate 60 abuts the end of the spindle extending through the spindle hole 16, thereby preventing the spindle from being pushed past the first handle body 62 in the direction indicated by the dashed arrow S.

[0055] Turn now Figure 3 The image shows a partially disassembled rear perspective view of the first handle 100. Figure 3 A spindle locking mechanism 71 is shown housed within a first handle 100. The spindle locking mechanism 71 has a first rotor 78 and a limiter 84. The first rotor 78 includes a spindle bore 16a with a corresponding square cross-section for receiving a spindle (not shown) passing through it. Thus, the spindle is coupled to the first rotor 78 such that the first rotor 78 rotates with the spindle. The limiter 84 has teeth 86, a rotor bore 87 in which the first rotor 78 is located, and a channel 88. The first rotor 78 has a recess 82 for receiving the teeth 86. Furthermore, a motor 98, a first bevel gear 96, a second bevel gear 94, and a clutch gear 90 are also housed within the first handle 100. The motor 98 is electrically connected to a battery within battery holders 54a and 54b. The first bevel gear 96 is connected to the motor 98, and the second bevel gear 94 meshes with the first bevel gear 96, such that the first and second bevel gears are perpendicular. The second bevel gear 94 meshes with the clutch gear 90. The clutch gear 90 includes a protrusion in the form of a pin 92 that inserts into a channel 88 of the limiter 84.

[0056] Now refer to Figure 4a and 4b Describe the operation of the spindle locking mechanism 71. Figure 4a A spindle locking mechanism 71 in an engaged state is shown, in which the first rotor 78 and the spindle located in the spindle hole 16a are prevented from rotating. Figure 4bThe spindle locking mechanism 71 in the separated state is shown. In the separated state, the first rotor 78 and the spindle connected in the spindle hole 16a can rotate. Figure 4a and 4b Some components of the first hand in the design were removed for ease of understanding.

[0057] During operation, the first bevel gear 96 is driven by the motor 98, and subsequently drives the second bevel gear 94 and the clutch gear 90. The bevel gears are used to change the axis of rotation, allowing the motor to be mounted at a 90° angle to the axis of rotation of the clutch gear 90. This arrangement reduces the required space and thus the size of the handle body 62. To disengage the spindle locking mechanism 71, the clutch gear 90 rotates clockwise (e.g., ...). Figure 3 (As shown by the dashed arrow E in the diagram). As the clutch gear rotates, pin 92 abuts against the upper edge of channel 88, forcing limiter 84 to move linearly upward within handle body 62 (as shown by the dashed arrow E in the diagram). Figure 4a (As shown in the Z direction). As the limiter 84 moves upward, the teeth 86 of the limiter 84 separate from the recess 82 of the first rotor 78 (as shown in the Z direction). Figure 4b (as shown in the diagram). In this separated state, the first rotor 78 and thus the spindle are allowed to rotate without being obstructed by the teeth 86 of the limiter 84.

[0058] To engage the spindle locking mechanism 71, the motor is run in the opposite direction, causing the clutch gear 90 to rotate counterclockwise. As the clutch gear 90 rotates, the pin 92 abuts against the lower inner edge of the channel 88, forcing the limiter 84 to move linearly downward (in the direction opposite to the Z direction). As the limiter 84 moves downward, the teeth 86 of the limiter 84 engage with the recess 82 of the first rotor 78 (as shown in the image). Figure 4a (As shown in the diagram). In this engaged state, the first rotor 78 and thus the spindle are prevented from rotating.

[0059] The spindle locking mechanism 71 can be engaged by gravity and / or by the force applied by the conical spring 99 attached to the first handle body 62. As the limiter component 84 moves upward (along the Z direction), the top of the limiter 84 compresses the conical spring 99. The biasing force applied by the conical spring 99 and gravity are sufficient to force the limiter 84 downward (in the opposite direction to the Z direction) and engage. Figure 4a The engagement state is shown. This is particularly advantageous in the event of a malfunction of motor 98 (e.g., if the battery is dead, the motor has no power source). If motor 98 malfunctions, the spindle locking mechanism can automatically return to the engaged state. If the spindle locking mechanism 71 remains in the disengaged state, the spindle can be rotated to operate the locking mechanism 1, and thus the door to which the locking mechanism 1 is mounted can be opened.

[0060] The spindle locking mechanism 71 is configured to automatically return to the engaged state after a predetermined time period. The motor 98 is configured to hold the limiter 84 in the disengaged state for a predetermined time period and, after the predetermined time period has elapsed, engage the spindle locking mechanism 71. The motor 98 actuates the limiter upon receiving a signal from an electronic mechanism (described below). The predetermined time period can be adjusted by the user; alternatively, the user can deselect the predetermined time period if they wish to prevent locking while the limiter is still engaged.

[0061] Return to reference Figure 3 The first handle assembly 100 has a direction sensor that detects the orientation of the spindle inserted into the spindle hole 16. The direction sensor has a Hall sensor 70 connected to the first handle body 62, a second rotor 76 having a magnet 74, and an electronic mechanism (described below) for interpreting the data generated by the Hall sensor 70. The second rotor 76 is connected to the first rotor 78, and is thus configured to rotate together with the first rotor 78 and the spindle. The spindle can rotate the second rotor 76 and the magnet 74, thereby changing the magnetic field strength at the Hall sensor 70. At a given point in time, the Hall sensor 70 detects the changing magnetic field and sends a signal to the electronic mechanism, which interprets the data to determine the orientation of the magnet and thus the spindle.

[0062] If the orientation sensor determines that the spindle and limiter 84 are not aligned, i.e. when the recess 82 of the rotor 78 rotates relative to the tooth 86 of the limiter 84, the electronic mechanism prevents the motor 98 from returning the spindle locking mechanism 71 to the engaged state after a predetermined amount of time.

[0063] Attempting to return the spindle locking mechanism 71 to the engaged state while the rotor 78 is not aligned with the limiter 84 will damage the spindle locking mechanism 71, gears (96, 94, and 92), and motor 98. For example, if the limiter 84 is moved downwards (along the axis of rotation) while the rotor 78 is already rotating... Figure 4a If the Z-direction is reversed (as shown in the diagram), the teeth 86 of the limiter 84 will not engage with the recess 82 of the rotor 78 as required for the normal operation of the spindle locking mechanism 71. Instead, the teeth 86 will abut against the outer circumferential surface of the rotor 78. If the outer circumferential surface of the rotor 78 prevents the limiter 84 from moving downward, the motor may cause the gears (96, 94, and 92) to jump, which may wear the gear teeth or even shear the gear teeth.

[0064] Now go to Figure 5The image shows a partially exploded perspective view of the second handle 200. The second handle assembly 200 includes a lever handle 202, a fingerprint scanner 204, a second handle housing 206, a reinforcement 208, a speaker 210, and an LED light 212. The fingerprint scanner 204 is housed within the lever handle 202. The lever handle 202 includes a finger opening 203 through which a capacitive fingerprint reader 205 can be accessed. The reinforcement 208 is made of hardened cast stainless steel. Located behind the reinforcement 208 are the LED light 212 and the speaker 210. The LED light 212 serves as an indicator signaling to the user that the spindle locking mechanism 71 has disengaged.

[0065] In operation, the user grasps the lever handle 202 and places their finger or thumb on the capacitive fingerprint reader 205. The capacitive fingerprint reader 205 then scans the fingerprint and sends the fingerprint data to the authentication unit (described below). The location of the capacitive fingerprint reader 205 is particularly advantageous because it allows the user to complete the grasping of the lever handle 202 and placement of their finger or thumb on the capacitive fingerprint reader 205 with a single action. This contrasts with conventional door locks that typically include fingerprint scanners spaced apart from the door handle. In this configuration, the user is forced to place their fingerprint on the fingerprint reader and then move their hand to grasp the handle, resulting in a delay in opening the door.

[0066] Turn now Figure 6 The diagram shows a perspective view of the spindle 300 used in the lock assembly 500. The first handle 100, the lock mechanism 1, and the second handle 200 can be connected together by inserting the spindle 300 through the spindle hole 16. The spindle 300 is elongated and substantially cuboid, with a square cross-section. The spindle 300 also includes a fragile portion, indicated by the dashed line F, formed by a groove 302 in the body of the spindle 300.

[0067] In use, the spindle 300 is connected to the lever handle 202 through the spindle hole 16. When the lever handle 202 rotates, the spindle rotates accordingly. The depth of the groove 302 is calculated such that the fragile part F breaks when a predetermined amount of force is applied. For example, if an attacker attempts to forcefully turn the lever handle 202 or the spindle 300 while the spindle locking mechanism 71 is still engaged, the applied force will exceed the predetermined amount, and the spindle 300 will break preferentially at the fragile part F. The predetermined amount of force is calculated such that the spindle will remain intact during normal operation. Therefore, the fragile part F protects both the spindle locking mechanism 71 and the locking mechanism 1.

[0068] refer to Figure 1 and 6The fragile part F is also positioned along the main body of the spindle 300 such that, in the event of breakage of the spindle 300, a portion of the spindle 300 is retained within the locking mechanism 1 of the lock assembly 500 and connected to the spindle locking mechanism 71 within the handle 100. The fragile part F is also positioned such that, in the event of breakage of the spindle 300, the broken end of the spindle 300 is flush with the front cover plate 3 of the locking mechanism 1.

[0069] The spindle has a spindle stop device in the form of protrusions 302a and 302b. Protrusions 302a and 302b extend from the spindle and have a width greater than that of the spindle bore 16. Protrusions 302a and 302b prevent the spindle 300 from being pulled past the rotor 78 and the spindle bore 16. To install the spindle, handles 100 and 200 are mounted on the door, and the spindle is inserted through the handle body 62. Then, a plate 60 is secured to the end to prevent the spindle from being pushed backward past the assembly.

[0070] In some cases, an attacker might attempt to remove the damaged spindle 300 to insert the second spindle. The second spindle could then be forcibly rotated to operate the locking mechanism 1, causing the locking latch 4 to retract. Because the damaged spindle lacks a protrusion from the front cover plate 3 of the locking mechanism 1 (which could be easily gripped and pulled), the location of the fragile part F makes it difficult for an attacker to remove the damaged spindle 300. Even if an attacker successfully grips the damaged spindle 300, protrusions 302a and 302b prevent the damaged spindle 300 from being pulled through the spindle hole 16. In some embodiments, an attacker might attempt to remove the damaged spindle 300 by pushing it through the spindle hole 16 and the first handle 100. However, the reinforcing plate 60 prevents the spindle 300 from being pushed through the first handle body 62. The fragile part F, protrusions 302a and 302b, and the reinforcing plate 60 improve the security of the lock assembly 500 and prevent the damaged spindle portion from being removed from the outside of the handle assembly.

[0071] Turn Figure 7 It provides an operating spindle locking mechanism 71 (such as...) Figure 3 A schematic diagram of the electronic mechanism 600 (shown). The electronic mechanism 600 includes multiple components, some of which have been shown in the previously discussed figures. The electronic assembly 600 is located in the first handle 100 and the second handle 200. Figure 7 In the diagram, dashed arrows represent wireless communication interfaces between electronic components, while regular arrows represent wired communication interfaces between electronic components.

[0072] The first handle 100 includes a PCB 57, a Hall sensor 70, a motor 98, and a battery 412 located within respective battery holders 54a and 54b. The PCB 57 includes a Bluetooth Low Energy (BLE) module 404 for communication with a user equipment (UE) 400, an RF module 406 (e.g., an 868fsk module) for communication with a wireless router 402, a flash memory 408, and a microprocessor 410. The flash memory is configured to store fingerprint data belonging to an authorized user. The UE can be a mobile phone, tablet, laptop, key fob, or any similar electronic device. The motor 98, battery 412, and Hall sensor 70 are all connected to the PCB 57 via wired connections. The motor 98 is also directly connected to the battery 412, which provides power to the motor. The second handle 200 includes a fingerprint scanner 204, an LED light, and a speaker 210 (e.g., a Bluetooth Low Energy (BLE) module 404 for communication with a user equipment (UE) 400, an RF module 406 (e.g., an 868fsk module) for communication with a wireless router 402, a flash memory 408, and a microprocessor 410. Figure 5 (As shown).

[0073] Some components in the electronic device 600 form an authentication unit for verifying the user's identity. The authentication unit consists of a PCB 57, a fingerprint scanner 204, and a speaker 210.

[0074] Users can verify their identity using fingerprint scanner 204. In operation, the user places their finger or thumb on fingerprint scanner 204. Fingerprint scanner 204 collects fingerprint data and sends it to microprocessor 410 located within PCB 57. Microprocessor 410 compares the input fingerprint data with fingerprint data previously stored in flash memory 408. If microprocessor 410 determines that the input fingerprint data matches the stored fingerprint data, microprocessor 410 successfully identifies the user. If microprocessor 410 determines that the input fingerprint data does not match the stored fingerprint data, microprocessor 410 fails to successfully identify the user. If microprocessor 410 successfully identifies the user, microprocessor 410 sends a signal to motor 98 instructing the motor to disengage spindle locking mechanism 71. Spindle locking mechanism 71 moves as previously referenced. Figure 4a and 4b The described separation state.

[0075] Users can also verify their identity using the BLE module 404 and the UE 400. In operation, the user opens an application on their UE 400. This application instructs the UE 400 to send a BLE signal to the BLE module 404 to establish a connection between the UE 400 and the BLE module 404. Once the connection is established, the speaker 210 is configured to emit a "beep" sound to indicate to the user that the connection has been successfully established. Once the connection is successfully established, the application sends a BLE signal to the BLE module 404 to verify the user's identity. The BLE module 404 sends the received BLE signal to the microprocessor 410, which then sends a signal to the motor 98 to instruct the motor to disengage the spindle locking mechanism 71. The application may further require the user to enter a valid username, password, and / or code to verify the user's identity before sending the BLE signal to the BLE module 404.

[0076] Users can also verify their identity using the radio frequency module 406, the wireless router 402, and the UE 400. In operation, the user opens an application on the UE 400 configured to send a signal to the wireless router 402 to verify their identity (e.g., via Wi-Fi). The wireless router 402 then sends the verification signal to the radio frequency module 406. The radio frequency module 406 sends the received radio frequency signal to the microprocessor 410, which then sends a signal to the motor 98 to instruct the motor to disengage the spindle locking mechanism 71.

[0077] Two or more of the above processes can be combined to create a multi-factor authentication method. Advantageously, multi-factor authentication ensures that a user's credentials are not easily compromised.

[0078] The microprocessor 410 is also configured to send a signal to the motor 98 to instruct the motor 98 to return the spindle locking mechanism 71 to the engaged state after a predetermined time amount. The user can reprogram the microprocessor using an application on the UE 400 to adjust the value of the predetermined time amount. As previously mentioned, the microprocessor is also configured to process and interpret the output data received from the Hall sensor 70 to determine the spindle orientation. If the microprocessor determines that the spindle 300 and the limiter 84 are misaligned, the microprocessor will not send a signal to the motor 98 with the instruction to return the spindle locking mechanism 71 to the engaged state.

[0079] The described handle assembly, including the first handle 100 and the second handle 200, is particularly advantageous because it minimizes the amount of electrical energy required to operate the lock while allowing the user to enjoy the benefits of an electronically controllable lock. As the handle 202 rotates, the spindle rotates accordingly, causing the latch (e.g., latch 4) to retract. The work required to retract the latch 4 is generated by the user manually turning the lever handle 202. Therefore, retracting the latch does not consume the electrical energy supply of the lock assembly 500.

[0080] Simultaneously, the electronic mechanism 600 controls when the latch 4 can retract, thereby ensuring that only authorized users can open the door. The electronic mechanism controls when the latch can retract by using a spindle locking mechanism 71. The energy required to move the spindle locking mechanism 71 from the engaged state to the disengaged state and from the disengaged state to the engaged state is minimal. Therefore, the lock assembly can be operated using the minimum amount of energy provided by the battery 412. This extends the lifespan of the battery 412.

[0081] Return to reference Figure 1 The handle assembly, including the first handle 100 and the second handle 200, can be used with a range of different locking mechanisms. A particularly advantageous locking mechanism 1 is described in the applicant's GB patent applications GB2584100 and GB2564225, which further reduces the energy required to operate the entire locking assembly 500.

[0082] Now refer to Figure 8 , 9a Section 9b briefly describes the structure and operation of locking mechanism 1. Now turn to Figure 8 A partially exploded view of a locking mechanism 1 is shown. The locking mechanism 1 includes a housing 2, which has a generally cubic shape and is configured to be recessed into the edge of a door (not shown). The housing 2 houses a latch 4 and a spring lock 5. The latch 4 is shown in a retracted position within the housing 2. The housing 2 also has a follower with a spindle hole 16 for receiving a spindle (not shown) passing through it. The follower is connected to a spindle rod 8. On the front surface of the housing 2, a trigger 10 is provided, which is operatively connected to a drive plate 6, which is subsequently connected to the latch 4 (described below). Extending vertically from the drive plate 6 is a drive plate pin 18. During operation, the drive plate pin 18 can be raised via the spindle rod 8. The housing 2 has a keyhole 14 in which a lock cylinder (not shown) (such as a European lock cylinder) can be located.

[0083] The locking mechanism 1 may also include a remote locking unit (not shown) to form a multi-point locking. The remote locking unit is operatively connected to the automatic actuation mechanism via a drive rod (not shown) connected to the drive plate 6.

[0084] Figure 9a and 9b The rear side of the locking mechanism 1 is shown, with a portion of the housing 2 removed. Figure 9a In the middle, the locking mechanism 1 is ready to be actuated. Figure 9a In the middle, the latch is in the retracted position. Figure 9b The lock mechanism 1 is shown after it has been actuated and the latch 4 has been driven to the extended position.

[0085] The trigger 10 is configured to be in a depressed state when a door with a locking mechanism is closed. The trigger 10 has a tooth 34 at its rear end that engages with a shoulder 32 disposed on the drive plate 6. The trigger 10 includes features to bias the trigger to... Figure 9a The biasing device (not shown) is depicted in the preparatory position. Tooth 34 prevents the drive plate 6 from moving downwards (i.e., moving in the Y direction). When the trigger 10 is pressed, the trigger 10 and thus tooth 34 are pushed back into the housing 2, i.e., the trigger 10 and tooth 34 move in the X direction. Once tooth 34 has moved past shoulder 32, the drive plate 6 no longer remains in the raised position and can descend in the Y direction under the influence of gravity. In some embodiments (not shown), a biasing mechanism (such as a spring) may be present to assist the downward movement of the drive plate 6.

[0086] The automatic actuation mechanism also includes a linkage mechanism in the form of a pivot arm 20 that operably connects the drive plate 6 and the latch 4. The pivot arm 20 has a pivot pin 36 connected to the housing 2, about which the pivot arm 20 is rotatable. The pivot arm 20 has a drive pin 24 received within a channel 22 at the rear end of the latch 4. The drive plate 6 is provided with an arm 30 including a protrusion 26 that engages with a hole 28 in the pivot arm 20.

[0087] As the drive plate 6 descends in the Y direction, the protrusion 26 of the arm 30 abuts against the inner edge of the hole 28 in the pivot arm 20, causing the pivot arm 20 to rotate about the pivot pin 36. As the pivot arm 20 rotates in an arc, the drive pin 24 abuts against the inner surface of the slot 22 and drives the latch in the X direction, thereby extending the latch. The movement of the drive plate 6 drives any remote locking unit connected to the locking mechanism 1.

[0088] To retract latch 4 and reset the automatic actuation mechanism, the user can raise drive plate 6. The user rotates a handle connected via a spindle to the driven member and spindle rod 8. Spindle rod 8 raises drive plate pin 18, thereby raising drive plate 6. The raised drive plate 6 causes pivot arm 26 to move in the opposite direction, thus pulling latch 4 to the retracted position. The upward movement of drive plate 6 can also retract at least one other latch located in the remote locking unit in a conventional manner.

[0089] The latch and any other latches located in the remote locking unit (e.g., as described in GB2564225) can also be actuated by operating the lock cylinder located in the keyhole 14. Therefore, even if the battery 412 fails and the spindle locking mechanism 71 is engaged, the user can still retract the latch and one or more other latches using a regular key. This prevents the user from being unable to operate the mechanism in the event of a power or automatic actuation failure.

[0090] Because the described locking mechanism 1 is mechanically triggered when the door is closed, requiring no electrical energy to operate, the specific combination of locking mechanism 1 with the previously described handle assembly is advantageous. Therefore, the high energy requirements for extending and retracting the latch 4 or any remote locking unit are completely eliminated. This further protects the energy reserves of the battery 412 used within the locking assembly 500, and thus provides the high security benefits of multi-point locking and a significantly extended battery life for the electronic locking mechanism (e.g., no key required).
