RELATED APPLICATIONS

This application claims priority to australian provisional application No. 2017904088 filed on 10/2017, the entire contents of which are incorporated herein by reference.

The present application also relates to a PCT application entitled "Electronic Lockset Having Mode Selection" filed as international application date 10/10 in 2018 in the name of Assa Abloy Australia Pty Ltd and the entire contents of the related PCT application are incorporated herein by reference.

Technical Field

The present invention relates to an electronic lock for mounting on a door for moving a bolt relative to the door, comprising an electrically operated control mechanism which interacts between an inner manually operable member and an outer manually operable member to control movement of the bolt. The applicant has appreciated that electronic locks have particular application in the home security market, and it will be convenient to hereinafter describe the invention with reference to that particular application. However, it should be appreciated that electronic locks may have other applications.

Background

Traditionally, mechanical locks and locksets have been supplied to the residential security market. Users have a high degree of acceptance and understanding of how they can be used, and users are also reassured that they provide adequate functionality and security. In addition, some users want them to be familiar enough with their home mechanical lock so that they feel relieved when installing the lock, with the peripheral lock (rim lock) being particularly popular with DIY users.

Residential users obviously desire locks with the ability to prevent ingress from the outside to the inside, and often also want the ability to selectively prevent egress from the inside to the outside. Such selective locking may be referred to as a deadlock, and is generally preferred when, for example, no one is in the house during the day, to prevent unauthorized removal of items through the door.

More complex mechanical, electromechanical and electronic locks are commonly offered to the commercial security market. The locks are often installed by hard wiring and utilize an electric actuator to release an electric striker or magnetic lock. These locks are often keyless, controllable without a mechanical key, but use a keypad, a magnetic or electronic access card or key fob, and more recently a biometric scanner to provide a personal digital signature. While egress from the inside to the outside is typically accomplished by pressing a release button or the like at the inside of the door, these locks are typically monitored by a security system, often adding an extra layer of security by a personal security guard. Thus, there is typically no need to include a deadlock option in a business environment, as the security system will know who is in the building, and the security guards can block them from leaving if needed.

The applicant has appreciated that residential users are often exposed to these business safety options at work and are seeking to implement similar options at home. The ability to utilize keyless controls is particularly attractive, however users are often not prepared to pay for security systems for monitoring locks. Furthermore, users often tend to understand the way in which the lock works, or at least has the same level of reassurance as their existing residential security options, so that the lock will be able to have a degree of reliability in a similar manner to the existing residential security options. Thus, for the residential security market, complex locks, particularly those requiring hard wiring, are often rejected. Furthermore, the ability to select the operation of the lock to prohibit unauthorized egress from the interior to the exterior would be preferable.

The reference herein to a patent document or to other material which is given as prior art is not to be taken as an admission that the document or material was known in australia or that the information it contains was part of the common general knowledge as at the priority date of any of the claims.

Disclosure of Invention

According to the present invention, there is provided an electronic lock for installation on a door to control movement of a bolt, the electronic lock comprising: an outer body for positioning on an exterior side of the door, having an outer manually operable member; and an inner body for positioning on an inside of the door, each of the outer and inner manually operable members being rotatable to move the plug from the outside and inside of the door respectively; at least an external user interface configured to receive user input from an outside of the door; an electrically-powered control mechanism in communication with the external user interface to control operation of the inner manually-operable member and the outer manually-operable member, wherein electrically-powered control mechanism comprises an electrically-powered control circuit adapted to process the user input and cause the electrically-powered control mechanism to adopt an access mode in which at least the outer manually-operable member becomes operable to move the plug, or a protection mode in which the outer manually-operable member and the inner manually-operable member each become inoperable to move the plug. The inner manually operable member and the outer manually operable member may take any suitable form provided that they are engageable by a user's hand and rotatable about an axis. It is further preferred that the rotational axis of the inner manually operable member is aligned so as to be coaxial with the rotational axis of the outer manually operable member, however this is not essential.

The electrically powered control mechanism is not limited to operating in the modes as mentioned above and the electrical control circuit may also be adapted to process the user input and cause the electrically powered control mechanism to adopt a pass through mode in which the outer manually operable member and the inner manually operable member become operable. Further, the electric control circuit may be further adapted to process the user input and cause the electric control mechanism to adopt a privacy mode in which the outer manually operable member becomes inoperable and the inner manually operable member becomes operable. Still further, the electric control circuit may be adapted to cause the electric control mechanism to switch to a safe mode after a selected period of time when the electric control mechanism is in an access mode, a protection mode, a pass-through mode, or an escape mode. Furthermore, the electric control circuit may be adapted to process the user input and cause the electric control mechanism to enter an escape mode in which at least the inner manually operable member becomes operable. However, it is preferred that the electronic lockset includes an internal user interface configured to receive user inputs from an interior side of the door, wherein the electronic control circuitry is adapted to process the user inputs to cause the electronic control mechanism to enter an escape mode in which at least the internal manually operable member becomes operable. The internal user interface may take any suitable form which may include any one or combination of a keypad, a reader or a device for receiving electronic or magnetic signals, biometric signatures, and forms part of the inner body.

The user input may comprise any one or more of the following user credentials for identifying the user: user-selected user credentials to select the mode for adoption by the electrically-controlled mechanism, temporary user credentials to enable user selection by the user within a set period of time based on the user credentials, maintenance user credentials to provide the user with information regarding performance of the electronic lock, and primary user credentials to provide the user with authority to program the electrically-controlled mechanism at the time of installation of the electronic lock.

It is further preferred that the external user interface comprises any one or combination of a keypad, a reader or a device for receiving electronic or magnetic signals, biometric signatures, and forms part of the inner body.

The electrically operated control mechanism may take any suitable form to control the interaction between the inner manually operable member and the bolt and the outer manually operable member and the bolt. In one form, the electrical control mechanism includes an external coupling mechanism within the outer body for interaction between the outer manually operable member and the plug, the external coupling mechanism being adjustable between engaged and disengaged conditions to render the outer manually operable member operable or inoperable respectively, and an internal coupling mechanism within the inner body for interaction between the inner manually operable member and the plug, the internal coupling mechanism being adjustable between engaged and disengaged conditions to render the inner manually operable member operable or inoperable respectively. The manner in which the inner and outer couplings are adjusted may take any suitable form, including: providing an internal electric actuator within the inner body that when energized adjusts a condition of the internal coupling; and providing an external electric actuator within the outer body that when energized adjusts a condition of the external coupling. In a preferred form, the inner electric actuator has an inner pawl and the outer electric actuator has an outer pawl, the inner and outer pawls each being adjustable between an active position and an inactive position in which they cause their respective inner and outer couplings to become disengaged and engaged, respectively. In this preferred form, each of the inner and outer couplers may include first and second members, each first member being associated with the outer or inner manually operable member respectively for rotation about an axis when the outer or inner manually operable member is operated, the second member being associated with the first member for rotation therewith about the axis when the coupling mechanism is in the engaged condition, the first member being rotatable relative to the second mechanism when the coupling mechanism is in the disengaged condition, and the second mechanism being associated with the plug such that rotation of the second member by the first member moves the plug. Also, in this preferred form, the inner and outer couplers may each include: biasing means for biasing each respective first member in an axial direction towards each respective second member; and a pawl movable in a direction substantially perpendicular to the axis to move each respective first member in an axial direction away from each respective second member. The preferred embodiment includes each pawl pivoting about an axis relative to its respective inner or outer body, and thus the term "substantially perpendicular" is intended to include arcuate movement toward and away from the axis. However, the specific form of the internal electric actuator, the internal coupling, the external electric actuator and the external coupling may be different from the above-described form. An alternative arrangement may include each pawl providing a connection between its respective first and second members when the respective coupler is in the engaged condition. In this alternative arrangement, the pawl will be movable relative to the first and second members when the coupler is adjusted between the engaged and disengaged conditions, and movable with both the first and second members when in the engaged condition.

Preferably, the electrical control mechanism includes a power source, particularly a stand-alone power source that may be provided by a battery power source, although other options are clearly possible. It is further preferred that the electronic lockset includes power terminals accessible from outside the door when the outer body is installed to supply auxiliary power to the power source. This has the advantage that auxiliary power is most likely provided in the form of a separate battery or the like in the event of a power supply failure or power depletion.

It is further preferred that the electrical control circuit is further adapted to monitor electrical conditions of said power source, including power supply conditions and power supply fault conditions between said power source and said electrical control mechanism. It is also preferred to include a further main setting user input for providing the user with permission to set a preferred mode for adoption by the electrically-operated control mechanism in the event of the power supply failure condition. This has the following advantages: the electric control mechanism is allowed to adopt a so-called pass-through mode, often referred to as fail-open, in the event of a power failure event, or alternatively a protection mode, often referred to as fail-close, in the event of a power failure event. It will be apparent that the electrical control mechanism may also employ a privacy mode, for example in the event of a power failure, which will allow a user to leave the asset while preventing, for example, an unauthorized user from accessing the asset when power has failed.

The electric control mechanism may include an inner motor and an outer motor for adjusting the inner pawl and the outer pawl, respectively. In a preferred embodiment, each of the inner and outer motors includes an output shaft, with each pawl having a driven member attached to each output shaft so as to be movable there with rotation of the shaft. However, in the event that the pawl must be able to move with the first and second members when in the engaged condition, the motor will need to interact with the pawl rather than be attached. Alternatively, the electric control mechanism may include a single motor to adjust the inner and outer pawls.

The electronic lockset can include a bolt in any suitable form, including a latch bolt, a locking bolt, or a swing bolt. The plug may form part of a core insert assembly or a tube assembly for positioning in a void formed in a side edge of the door. Alternatively, the plug may be housed in the inner body. With the plug received in the inner body, the electronic lockset may be referred to as an exterior electronic lockset.

The electronic lockset preferably includes a visual indicator operable by the power control circuit to indicate at least one mode of the power control mechanism and a condition of the power source.

It will be convenient to describe the invention in more detail below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. The drawings and the following detailed description are merely illustrative of how the invention may be practiced. The particular forms and arrangements of the various features shown are not to be considered as limiting the invention.

Detailed Description

Referring initially to fig. 1, an electronic lockset 1 is illustrated in accordance with an embodiment of the present invention. The electronic lock 1 is adapted to be mounted on a door (not shown) such that the inner body 4 is located on the inside of the door and the outer body 3 is located on the outside of the door. Further, the embodiment of the electronic lockset 1 as shown in fig. 1 is shown to include a tubular latch bolt assembly 2, a head of a latch bolt 5 extending out of a latch bolt housing 6. Although fig. 1 shows a tubular latch bolt assembly 2, it is apparent that the electronic lockset can be adapted to other forms of mortise lock assemblies including lock or swing bolts.

The electronic lock 1 further comprises an outer manually operable member 8 and an inner manually operable member 7 (see fig. 2), each shown in the form of a lever. The electronic lock 1 of the present invention is not limited to use with levers only, and the inner manually operable member 7 and the outer manually operable member 8 may take other forms including knobs.

The electronic lock 1 further comprises an external user interface 9 and an internal user interface 10 associated with the external body 3 and the internal body 4, respectively. The illustrated embodiment of the internal user interface 10 and the external user interface 9 is a keypad arrangement (seen more clearly in fig. 2), however, the electronic lockset 1 may alternatively or additionally include an RFID reader, or biometric reader, for receiving electronic or magnetic signals from an access card or the like. More specifically, the electronic lock 1 of the present invention is not limited to including a keypad arrangement as the user interface.

It should also be noted from fig. 1 that the electronic lock 1 comprises an internal spindle 11 extending between the internal body 4 and the tubular latch bolt 2. An equivalent outer mandrel 12 (see fig. 2) extends between the outer body 3 and the tubular latch bolt assembly 2. Furthermore, fig. 1 shows a wire harness 13 extending between the inner body 4 and the outer body 3, said wire harness 13 allowing electronic communication between the inner body 4 and the outer body 3 for reasons that will be explained later in the description.

As shown in fig. 8, another option is to have the plug assembly form part of the inner body, as in the case of the exterior latch assembly. More specifically, the present invention is not limited to use with a tubular latch bolt assembly as shown in FIG. 1.

As shown in fig. 8, the electronic lockset 1 includes equivalent inner and

outer bodies

104, 103 on the inside and outside of the door (not shown), respectively. The plug assembly 102 is associated with an inner body 104, and fig. 8 shows the head of a latch plug 105 extending out of the inner body 104. Fig. 8 also shows an outer manually operable member 108, an inner manually operable member 107, both in the form of a knob. Further, the external user interface 109 and the internal user interface 110 are in the form of RFID readers.

Referring now to fig. 2, there is shown the inner body 4 and outer body 3 each having an inner cap 14 and an outer cap 15 respectively. The inner and outer covers 14, 15 each cover the keypads 37, 38 of the inner and outer user interfaces 10, 9 respectively. With particular reference to the external user interface 9, there is shown a series of twelve keys 16, the twelve keys 16 allowing user input to adjust the operation of the electronic lockset 1. The external user interface shown in fig. 2 is a light panel 17 with twelve LEDs 39 thereon, the twelve LEDs 39 serving as visual indicators to visually indicate to the user the function of the electronic lockset 1. It will be appreciated that the internal user interface 10 comprises an equivalent keypad 72 with lights 40, which equivalent keypad 72 operates in the same way as the external user interface 9.

The preferred embodiment of the electronic lockset 1 shown in fig. 2 also includes an electronic control mechanism that broadly includes an electronic control circuit 18, an external coupler 19, an internal coupler 20, and a power source 21. Referring specifically to the external coupling 19, it can be appreciated that it includes a first member 22 and a second member 23. The first member 22 is positioned to interact with the outer handle 8 (see also fig. 4), while the second member 23 is positioned to interact with the outer spindle 12. Similarly, with respect to the internal coupling 20, the respective first member 24 is positioned to interact with the internal handle 7, while the respective second member 25 is positioned to interact with the internal spindle 11. Further, the outer pawl 26 is positioned between the first and

second members

22, 23 of the outer coupler, while the inner pawl 27 is positioned between the first and second members 24, 25 of the inner coupler 20. The preferred latch bolt assembly 2 interacts with each of the inner spindle 11 and the outer spindle 12 in the following manner: so that the operation of the outer manually operable member 8 is independent of the operation of the inner manually operable member 7. One preferred form of the latch bolt assembly 2 is a split hub tubular latch bolt assembly.

Fig. 2 also shows an internal motor 28 and an external motor 29, each operable to adjust the position of the pawls 27, 26 respectively, to achieve a function that will be described later in the specification. It should be noted that for the purposes of this description, the internal motor 28 and the internal pawl 27 combine to form an internal electric actuator, while the external motor 29 and the external pawl 26 combine to form an external electric actuator.

Reference is now made to fig. 3, which shows in general terms the outer manually operable member 8, the outer body 3, the outer motor 29, the outer pawl 26 and the second member 23 of the outer coupling 19. Fig. 3 shows the pawl 26 in the active position. As can be appreciated from fig. 4, with the external pawl 26 in the active position, the first member 22 is spaced from the second member 23 of the external coupling 19 such that rotation of the external manually operable member 8 does not result in rotation of the second member 23. It should also be noted from fig. 4 that a biasing spring 30 acts between the first member 22 and the outer manually operable member 8 to urge the first member 22 towards the second member 23. However, due to the position of the external pawl 26, the first member 22 is prevented from engaging the second member 23. In the arrangement shown in fig. 3 and 4, the external coupling 19 is considered to be in the disengaged position, which corresponds to the external pawl 26 being in the active position.

In contrast, fig. 5 shows the external pawl 26 in an inactive condition. It should be noted that the external motor 29 has been energized to rotate its output shaft 31, thereby moving the driven member 34 along said output shaft 31. The free end 32 of the external pawl 26 is captured by the driven member 34 such that movement of the driven member 34 causes the external pawl 26 to pivot about its fixed end 33. As a result of the movement of the external pawl 26, it can be appreciated from fig. 6 that the first member 22 has moved under the influence of the biasing spring 30 to engage the second member 23. It will be appreciated that with the first member 22 now engaging the second member 23, rotation of the externally manually operable member 8 will result in rotation of the second member 23. Furthermore, when the electronic lock 1 is assembled, the external spindle 12 is located within a socket 35 (see fig. 6) of the second member 23, such that rotation of the external manually operable member 8 will cause the bolt 5 to move relative to the latch bolt housing 6.

It can also be noted from fig. 3 (and 5) that the lock 1 comprises power terminals 36 located outside the outer body 3, said power terminals 36 being connected to the power supply 21. This enables auxiliary power to be supplied to the power supply in the event of a power supply failure. The power supply terminals may take any form and are not limited to the form of the power supply terminals shown. The power terminals may, for example, take the form of sockets for receiving plugs from cables associated with the auxiliary power supply. This arrangement may include a USB socket connectable to the battery of the mobile phone.

While the electrical control mechanism, and in particular the adjustment of the outer coupling 9, has been described with reference to fig. 3 to 6, it will be appreciated that the electrical control mechanism can adjust the inner coupling 20 in the same manner. The electric control mechanism receives user input from either the internal user interface 10 or the external user interface 9 to adjust the internal coupling 20 and/or the external coupling 19, since the wiring harness 13 connects the electric control mechanism with both the internal electric actuator and the external electric actuator. This arrangement allows for independent control of the adjustment of the inner coupling 20 and the outer coupling 19.

It should also be appreciated that the manner in which the inner coupling 20 and the outer coupling 19 are adjusted between the engaged condition and the disengaged condition may differ from that shown. Taking the internal coupling 20 as an example, rather than adjusting the pawl 27 to cause relative axial movement between the first and second members 24, adjusting the internal pawl 27 itself may cause the internal pawl 27 to itself create a connection between the first and second members 24, 25.

The user input will typically include user credentials identifying the user. Where the user interface is in the form of a keypad, the user credentials may include a selected combination of numbers or letters that have been predefined to identify the user. Alternatively, where the user interface is a magnetic or electronic access card, a signal is supplied to the user interface magnetically or electronically to identify the user. Where the user interface includes a biometric reader, the user may use a fingerprint or the like to provide the predefined user credentials. Clearly, other forms of user credential provisioning are possible without the use of a mechanical key.

The user input also preferably includes a user selection for selecting a mode to be employed by the power control mechanism. The electrically controlled mechanism is operable in an access mode wherein at least the outer manually operable member becomes operable to move the bolt. The electrically controlled mechanism may also be operated in a protected mode wherein the outer manually operable member and the inner manually operable member each become inoperable to move the plug. The protection mode effectively "deadlocks" the lock, and it may be selected at either the internal user interface or the external user interface. The electrically controlled mechanism may also be operable in a mode wherein the outer manually operable member and the inner manually operable member become operable to move the bolt. The electrically controlled mechanism may also be operable in an escape mode wherein at least the inner manually operable member becomes operable to move the bolt. The electrical control mechanism may also be operable in a privacy mode in which the outer manually operable member becomes inoperable and the inner manually operable member becomes operable to move the plug. A privacy mode may be selected from the internal user interface and the external user interface rendered inoperable, thereby providing a "private space" internally to the user. The electrically controlled mechanism may also be operated in a safe mode wherein after a period of time the outer manually operable member becomes inoperable and the inner manually operable member becomes operable to move the plug.

These user selections may be limited according to user credentials received by the user interface. Further, the user credentials may identify a user having authority to perform maintenance on the lock, and once identified, the user selections may include a maintenance user input to gather information from the power control circuit regarding the performance of the electronic lock. Still further, the user credentials may identify the user as a master controller authorized to have master control of the lock, and once identified, the user selections may include a master user input to override existing programming of the lock and reprogram the lock, or more particularly the power control circuit. For example, the master user may set a mode for the electric control mechanism to adopt in the event of a power supply failure condition. Alternatively, the user credentials may identify the user as a temporary user, and in such cases, the user has limited time and mode for operation of the motorized control mechanism. For example, the temporary user may be a merchant who needs to temporarily enter a building to perform certain appointment functions. Maintenance and main user input can be performed when the lockset is installed. Preferably, the visual indicator provides a unique indication of the selected user input. It is further preferred that the visual indicator provides an indication of whether the user credentials have been accepted or rejected, in particular for the user selected mode of operation. The LEDs 39, 40 may illuminate in a range of colors to indicate whether the user credentials have been accepted or rejected, and may flash in a unique sequence to indicate the mode employed by the motorized control mechanism. Obviously, other configurations of visual indicators are possible.

Fig. 7 shows a flow chart of how an electronic lockset can be operated. To unlock 50 the lock, user credentials 51 are provided to the internal user interface or the external user interface to identify the user. If the user is authorized, the user may supply user input to, for example, cause the electrically-powered control mechanism to adjust the internal or external electrically-powered actuators to assume, for example, pass-through mode 53. Obviously, another choice of operating mode is the access mode. To lock 60 the lock, having entered user credentials, the user input may include an escape mode 61 in which the external coupler is disengaged and the internal coupler is engaged 62. Alternatively, the user input may adopt a protected mode 63 in which both the inner and outer couplings are disengaged 64.

It will also be appreciated that the electrical control circuit may control the mode of operation to adopt a preselected mode after a period of time, such that the lock may return to the escape or pass-through mode, for example after a user input has caused the pass-through mode. This pre-selection should be limited to adjustments by the primary user.

It will be appreciated from the foregoing that an electronic lockset as described previously herein provides a relatively simple option for providing a deadlock solution in an electronic lockset. The ability to effectively deadlock a lock from an external user interface is particularly unique.

Various changes and/or additions may be introduced into an electronic lockset as described hereinbefore without departing from the spirit or scope of the invention as defined by the claims.
