ELECTRONIC LOCK WITH WIRELESS EXTERIOR TO INTERIOR DOOR COMMUNICATION

TECHNICAL FIELD

The present disclosure relates generally to locksets. In particular, the present disclosure relates to a lockset that uses exterior to interior communication without cables.

BACKGROUND AND SUMMARY

Existing electronic locksets include wires to electrically connect their exterior and interior assemblies. The wires are used to send electrical signals between the exterior and interior assemblies. For example, the exterior assembly may include a user interface (e.g., a keypad, etc.) for inputting an authentication code, which is communicated to the interior assembly. If the interior assembly determines a valid authentication code was sent, then the interior assembly controls a motor to actuate a bolt between an extended position and a retracted position.

One challenge with the installation of the electronic locksets is electrically connecting the interior and exterior assemblies. This is a challenge because the wires need to be manipulated through a bore hole of a door. In some situations, the wires may become pinched or otherwise damaged during the installation process. As a result, the communication between the exterior and interior assemblies may become unreliable, which can cause the electronic lockset to operate improperly.

According to one aspect, this invention provides a lockset for securing a door with a bore hole. The lockset includes a latch assembly, an interior assembly, and an exterior assembly. The latch assembly includes a bolt movable between an extended position and a retracted position. The interior assembly is configured to electronically control movement of the bolt between the extended position and the retracted position. The exterior assembly includes a locking assembly configured to be mechanically coupled with the latch assembly. The interior assembly includes an interior wireless communication unit and the exterior assembly includes an exterior wireless communication unit that is configured to wirelessly communicate therebetween. In some embodiments, the exterior assembly includes a photovoltaic solar cell and the interior assembly includes a light source. The light source and the solar cell are configured for wirelessly communicating and for power transmission between the exterior and interior assemblies through a bore hole in the door.

In the example shown, the lockset system 100 includes an exterior assembly 102, an interior assembly 104, and a latch assembly 106. Typically, the exterior assembly 102 is mounted on the outside of a door 108, while the interior assembly 104 is mounted on the inside of the door 108. The latch assembly 106 is typically mounted in a bore hole 110 formed in the door 108. The bore hole 110 is also used for communication between the exterior assembly 102 and the interior assembly 104. As shown, the latch assembly 106 includes a bolt 112 movable between an extended position and a retracted position. Typically, the extended position relates to a locked position and the retracted position relates to an unlocked position. The term “interior” is broadly used to denote an area inside a door and “exterior” is also broadly used to mean an area outside a door. For example, with an exterior entry door, the exterior assembly 102 may be mounted outside a building and the interior assembly 104 may be mounted inside a building. In another example, with an interior door, the exterior assembly 102 may be mounted on the outside of a secured room located inside a building, and the interior assembly 104 may be mounted inside the secured room. The lockset system 100 is applicable to both interior and exterior doors. The lockset system 100 may also be used in such a way to secure any room with the exterior assembly 102 located on the outside and the interior assembly 104 located on the inside of the room.

In one embodiment, a warning condition may relate to a low battery level of the interior assembly 300, a low battery level of the exterior assembly 200 (FIG. 2), a fault of the interior assembly 300, a fault of the exterior assembly 200 (FIG. 2), or another aspect that the user should be notified of related to the lockset system 100 (FIG. 1). In one embodiment, the interior output device 306 may be embodied as a light communication device to notify the user through different colors of lights that signify different things. For example, the interior output device 306 may display a red light to notify the user of a warning condition of the exterior assembly 200 (FIG. 2). In another embodiment, the interior output device 306 may be embodied as an audible alarm to notify the user through different sounds produced. In another embodiment, the interior assembly 300 may have two interior output devices. One interior output device 306 relates to the interior assembly 300 and the other interior output device (not shown) relates to the exterior assembly 200 (FIG. 2). In another embodiment, the interior output device 306 may include LED lights that indicate the battery level of the interior assembly 300. In another embodiment the interior output device 306 may include LED lights that indicate the battery level of the exterior assembly 200 (FIG. 2).

In the embodiment shown, the power supply 308 is electrically connected to the interior controller 302. The interior controller 302 powers the other electrical components 304, 306 (e.g., the interior wireless communication unit 304 and interior output device 306). In another embodiment, the power supply 308 may be directly connected to the electrical components 304, 306. The power supply 308 may have other components to convert the power supplied to each of the components. In the example shown, the power supply 308 is located in the interior assembly 300. In another embodiment, the power supply 308 may be located outside of the interior assembly 300 to power the interior assembly 300 and its components 304, 306. In one embodiment, the power supply 308 may be embodied as batteries to supply power to the interior assembly 300. In another embodiment, the power supply 308 may be embodied as any device capable of providing power to the electrical components 302, 304, 306.

In one embodiment, the interior controller 302 may receive an authentication code from the exterior controller 202 (FIG. 2) through the exterior wireless communication unit 204 (FIG. 2). If the interior controller 302 receives a valid authentication code from the exterior controller 202 (FIG. 2) then the interior controller 302 may send a signal to the motor 314 to actuate the bolt 316 between the extended position and the retracted position. The interior controller 302 may also send a confirmation signal to the exterior controller 202 (FIG. 2) through the interior wireless communication unit 304 to the exterior wireless communication unit 202 (FIG. 2) for the exterior controller 202 (FIG. 2) to notify the user of the valid authentication code as described above.

In one embodiment, the interior controller 302 may receive status signals regarding the exterior assembly 200 (FIG. 2) from the exterior controller 202 (FIG. 2). The interior controller 302 may process the signals received and determine if there is a warning condition as described above. If the interior controller 302 determines a warning condition is present, such that a parameter regarding a warning condition exceeds a predetermined threshold, then the interior controller 302 outputs a notification through the interior output device 306. The notification may be used to allow a user of the lockset system 100 (FIG. 1) to know that there may be a fault in the system or a low battery level issue to consider.

In one embodiment, the exterior controller 202 may determine that the interior controller 302 has not received signals sent by the exterior controller 202 through the exterior wireless communication unit 204. After a determination that the interior controller 302 has not received signals sent by the exterior controller 202, the exterior controller 202 may attempt to resend the signals received from the user interface 208 to the interior controller 302. The exterior controller 202 may then output through the exterior output device 206 that the interior controller 302 has not received the signals sent by the exterior controller 202. The signals may not have been received either through a fault or maybe an obstruction in the way of communication with the bore hole 110. The exterior controller 202 may also temporarily store the signals received from the user interface 208 to reattempt to send the signals after a failed attempt at communicating with the interior controller 302. The exterior controller 202 may also process the signals to send a signal of a valid authentication code instead if the first attempt to communicate with the interior controller 302 failed.

In one embodiment, the communication between the exterior wireless communication unit 204 and the interior wireless communication unit 304 may be means for short field communication. The short field communication means may include the exterior wireless communication unit 204 and the interior wireless communication unit 304. In one embodiment, the short field communication means is capable of the functions described by the exterior communication unit 204 and the interior wireless communication unit 304. The short field communication means includes communication via at least one of visible light, infrared light, audible sound, or ultrasound. The short field communication means may include any device to achieve communication via at least one of visible light, infrared light, audible sound, or ultrasound. The communication between the exterior wireless communication unit 204 and the interior wireless communication unit 304 may be encoded. The exterior controller 202 and the interior controller 302 may encode the signals sent through the exterior wireless communication unit 204 and the interior wireless communication unit 304 to be decoded by a receiving controller 202 or 302. For example, if the exterior controller 202 sends an encoded signal through the exterior wireless communication unit 204, then the interior wireless communication unit 304 receives the encoded signal to be decoded by the interior controller 302.

FIG. 4A is a first part of a simplified flow chart showing an example operation of the exterior assembly 200. In the shown example, the method of operation 400 begins with operation 405 to initiate the process. After operation 405, the process continues to operation 410 where the exterior assembly 200 waits for an input from the user interface 208. After operation 410, the process continues to operation 415 where the exterior controller 202 checks the user interface 208 for user input. If there is no user input, the process returns to operation 410 to wait for the user input from the user interface 208. If there is a user input, the process continues to operation 420 where there is an evaluation from the exterior controller 202 on the exterior assembly 200 to see if there are any present warning conditions as described above. If there are warning conditions present, the process continues to operation 425 where the exterior controller 202 sends encoded signals of the warning conditions to the interior assembly 300 through the exterior wireless communication unit 204 to the interior wireless communication unit 304. More specifically, the exterior controller 202 sends encoded signals of the warning conditions to the interior controller 302 of the interior assembly 300. In another embodiment, the signals may be sent without being encoded.

After operation 425, the process continues to operation 430 where the interior controller 302 sends a signal to the interior output device 306 to notify the user of the warning condition. The interior output device 306 allows the user to know that there may be a fault or low battery level condition or another warning condition of the lockset system 100. In another embodiment, the exterior controller 202 may perform operations 420, 425, and 430 independently from a user input. The exterior controller 202 may periodically check for warning conditions of the exterior assembly 200 to send to the interior controller 302. The exterior controller 202 may also periodically send status updates to the interior controller 302. If there are no warning conditions of the exterior assembly 200, then the process continues to operation 435 where the exterior controller 202 sends encoded signals of the user input and status of the exterior assembly 200. In another embodiment, the exterior controller 202 may only send the encoded signals of the user input to the interior controller 302 when receiving user input from the user interface 208. In another embodiment, the exterior controller 202 may send the signals from the user interface 208 without being encoded to the interior controller 302. After operation 435, the process continues on to operation 440 where the method of operation 400 continues from FIG. 4A to FIG. 4B.

FIG. 4B is a second part of the simplified flow chart showing the example operation of the exterior assembly 200. In the shown example, the method of operation 400 continues with operation 440 to continue the process from FIG. 4A. After operation 440, the process continues to operation 445 where the interior controller 302 checks to see if it received signals from the exterior controller 202 through the interior wireless communication unit 304 from the exterior wireless communication unit 204. If it is determined that the interior assembly 300 did not receive signals from the exterior assembly 200, then the process continues to operation 450 where the user is notified that the interior assembly 300 did not receive any signals through the exterior output device 206. Operation 445 is determined by the exterior controller 202 not receiving a confirmation signal from the interior controller 302 of receiving the signals sent by the exterior controller 202 within a predetermined time interval. The exterior controller 202 may also reattempt to send the signals after not receiving the confirmation signal as described above. After operation 450, the process continues to operation 470 where the method of operation 400 ends. If the interior assembly 300 did receive the signals, then the process continues to operation 455 where the interior controller 302 verifies that the signals sent were a valid authentication code. In another embodiment, if the interior assembly 300 only received a status update or a warning condition from the exterior assembly 200, then the interior assembly may send back a confirmation signal. If it is determined that the user input is correct and is a valid authentication code, then the process continues to operation 460 where the interior controller 302 sends a confirmation signal of correct input to the exterior assembly 200 and the exterior assembly 200 will notify the user of a valid authentication code through the exterior output device 206 as described above. If it is determined that the user input is incorrect and is an invalid authentication code, then the process continues to operation 465 where the interior controller 302 sends a confirmation signal of an incorrect input to the exterior assembly 200, and the exterior assembly 200 will notify the user of an invalid authentication code through the exterior output device 206 as described above. After the user is notified of either an incorrect or correct input, the process continues to operation 470 where the method of operation 400 ends.

FIG. 5A is a first part of a simplified flow chart showing an example operation of the interior assembly 300. In the shown example, the method of operation 500 begins with operation 505 to initiate the process. After operation 505, the process continues to operation 510 where the interior assembly 300 waits for signals from the exterior assembly 200. In one embodiment, the interior controller 302 may be waiting to receive a signal from the exterior assembly 200 through the interior wireless communication unit 304. In one embodiment, the signals may be at least one of a user input, a status update of the exterior assembly 200, or a warning condition of the exterior assembly 200. After operation 510, the process continues to operation 515 where the interior controller 302 checks to see if there is a signal received from the exterior controller 202 through the exterior wireless communication unit 204 to the interior wireless communication unit 304. If there is no signal received, the process returns to operation 510 for the interior assembly 300 to wait for a signal from the exterior assembly 200. If the interior assembly 300 does receive a signal, then the process continues to operation 520 where the interior controller 302 decodes the signals received. In another embodiment, the interior controller 302 may just receive the signals if the signals are not encoded. After operation 520, the process continues to operation 525 where the interior controller 302 checks to see if any warning conditions were sent. In another embodiment, the interior controller 302 may also wait to receive warning conditions separately from waiting for a user input. The interior controller may receive status updates of the exterior assembly 200 in conjunction with the user input. If warning conditions were sent, the process continues to operation 530 where the interior assembly 300 will notify the user of a warning condition through the interior output device 306 as described above. If warning conditions were not sent by the exterior assembly 200 or the user was notified of the warning condition through the interior output device 306, the process continues to operation 535 where there is a check to see if the interior assembly 300 received user input from the exterior assembly 200. If there is no user input received, the process returns to operation 510 where the interior assembly 300 waits for a signal from the exterior assembly 200. If the interior assembly 300 received user input from the exterior assembly 200, the process continues to operation 540 where the method of operation 500 continues from FIG. 5A to FIG. 5B.

FIG. 5B is a second part of the simplified flow chart showing the example operation of the interior assembly 300. In the shown example, the method of operation 500 continues with operation 540 to continue the process from FIG. 5A. After operation 540, the process continues to operation 545 where the interior controller 302 verifies that the user input is correct and is a valid authentication code. If the user input is an incorrect signal and an invalid authentication code, then the process continues to operation 550 where the interior controller 302 sends a confirmation signal of an incorrect signal to the exterior assembly 200 through the interior wireless communication unit 304 to the exterior wireless communication unit 204. If the user input is a correct signal, then the process continues to operation 555 where the interior controller 302 sends a confirmation signal of the correct signal to the exterior assembly 200 through the interior wireless communication unit 304 to the exterior wireless communication unit 204. After operation 555, the process continues to operation 560 where the interior controller 302 processes the signal and determines whether the user input was to lock the lockset system 100 or to unlock the lockset system 100. If it is determined that the user input is to lock the lockset system 100, then the process continues to operation 565 where the interior controller 302 sends a signal to the motor 314 to actuate the bolt 316 to a locked position. If it is determined that the user input is to unlock the lockset system 100, then the process continues to operation 570 where the interior controller 302 sends a signal to the motor 314 to actuate the bolt 316 to an unlocked position. After the position of the bolt 316 is in the correct position in accordance to the user input sent by the exterior assembly 200, the process continues to operation 575 where the method of operation 500 ends.

FIG. 6 shows an example lockset system 600 according to an embodiment of the disclosure. In the example shown, the lockset system 600 includes an exterior assembly 602, an interior assembly 604, and a latch assembly 606. Typically, the exterior assembly 602 is mounted on the outside of a door 608, while the interior assembly 604 is mounted on the inside of the door 608. The latch assembly 606 is typically mounted in a bore hole 610 formed in the door 608. The bore hole 610 is also used for communication between the exterior assembly 602 and the interior assembly 604. In this embodiment, the lockset system 600 includes a solar cell 616 and a light source 618 (depicted for purposes of example in FIG. 6 as an LED light source).

The solar cell 616 is coupled to the exterior assembly 602 such that it can receive light from the light source 618 that is coupled to the interior assembly 604. The solar cell 616 may be any commercially available solar cell, such as 4.5 V photovoltaic solar cell. With a sufficiently powerful light source, such as a 10,000 millicandela white LED from Lumen Opt (Part No. SSL-LX100133XUWC), the light source 618 can power the exterior assembly 602. For example, the lockset system 600 may include electrical storage capacity (such as power supply 210 described with reference to FIG. 2) on the exterior assembly 602. In some embodiments, light source 618 may be activated to provide power to the exterior assembly 602 by way of the solar cell 616 when the electrical storage capacity levels reach below a voltage threshold or some other threshold that indicates low power.

In addition to providing power to the exterior assembly 602, the light source 618 may allow the interior assembly 604 and the exterior assembly 602 to communicate data. By way of example only, the data communicated between the exterior assembly 602 and the interior assembly 604 could include user input for authentication, user input for configuration, electrical storage levels on the exterior assembly 604, as well as the communications described herein with reference to FIGS. 1, 2, 3, 4 A, 4B, 5 A, and 5B. The lockset system 600 may also include similar components, and may also include similar operation, as the lockset systems shown and described herein with reference to FIGS. 1, 2, 3, 4 A, 4B, 5 A, and 5B.

The latch assembly 606 may include a bolt 612 (e.g., similar to bolt 112) movable between an extended position and a retracted position. Typically, the extended position relates to a locked position and the retracted position relates to an unlocked position. The exterior assembly may include a tail piece 614 that moves the bolt or the latch assembly 606 between the extended position and the retracted position. The term “interior” is broadly used to denote an area inside a door and “exterior” is also broadly used to mean an area outside a door. For example, with an exterior entry door, the exterior assembly 602 may be mounted outside a building and the interior assembly 604 may be mounted inside a building. In another example, with an interior door, the exterior assembly 602 may be mounted on the outside of a secured room located inside a building, and the interior assembly 604 may be mounted inside the secured room. The lockset system 600 is applicable to both interior and exterior doors. The lockset system 600 may also be used in such a way to secure any room with the exterior assembly 602 located on the outside and the interior assembly 604 located on the inside of the room. The lockset system 600 may also be used in a way where the exterior assembly 602 is located on the inside of the door and the interior assembly 604 is located on the outside of the door.

In the embodiment shown, the exterior assembly 602 includes a key hole (not shown) to receive a key (similar to key 114) to manually actuate the bolt 612 of the latch assembly 606 between the extended position and the retracted position. In one embodiment, the exterior assembly 602 and the interior assembly 604 may wirelessly communicate with each other through the bore hole 610. In some embodiments, the communications between the exterior assembly 602 and the interior assembly 604 could be duplex (e.g., with a light source coupled to the exterior assembly and a solar cell or receiver coupled to the interior assembly); embodiments are also contemplated in which the communications may be one-way from the exterior assembly 602 to the interior assembly 604.
