Traditional entryways into a dwelling typically contain an entry door system. The entry door allows ingress and egress to the dwelling. A typical entry door system includes a door frame that includes a plurality of hinge mechanisms that pivotably mount a door panel. The door panel typically includes a handle that has a latch mechanism that cooperates with a strike plate mounted in the frame to hold the door in a closed position. One or more locks can be provided to secure or lock the door in the close position. These conventional locks typically include a handle based or mounted lock that locks or secures the latch in the deployed position, thus locking the door relative to the frame. In addition, entry door systems can also include a deadbolt that provides a further and separate means for locking the door in the closed position.
A disadvantage of traditional door entry systems of this type are that they have a single or at most dual point of locking connection between the door panel and the frame. Hence, by applying the appropriate amount of force to the door panel at the locking sites, the door panel can typically be forced open. Further, the entry door system typically provides one or more seals between the frame and the door in an attempt to provide a fluid tight seal. However, the locking mechanisms themselves do not function as sealing elements, and there is typically an issue associated with these types of door panel seals. In many instances, the seals are not effective at preventing the transfer of environmental elements such as noise, weather, water, and insects from one side of the panel to the other side.
Prior attempts have been made to address these issues by using various types of weather stripping between the panels and frame. For example, the weather stripping may be a strip of felt, foam, or a pile of flexible synthetic material. In many instances, however, this weather stripping fails to act as a sufficient seal between the door panel and the frame. Another prevalent issue associated with seals formed between the door frame and the door panel or between adjacent panels is that these seals can become disjoined. Either intentionally or unintentionally, the alignment between the frame and the panel or between adjacent panels may be disturbed which can degrade the quality of the seal, since, in many instances, the integrity of the seal relies upon these members having certain positional relationships relative to one another.
The present invention is directed towards a door panel based or a frame based door lock assembly or system that can lock, seal and secure an entrance to a dwelling. The door lock assembly of the present invention can be formed and mounted within a door panel and has a movable locking element that, when deployed, locks and seals the door to the frame.
The present invention is directed to a door lock assembly that includes a deadbolt or drive assembly 720 that is adapted to mechanically cooperate with a movable locking assembly 520 so as to move the locking assembly between a locked position and an unlocked position. The present invention also includes a door latch assembly 810 that has integrated therewith a coupler element for coupling to the locking elements 522 of the movable locking assembly 520. The latch assembly operates independent of the operation of the locking assembly.
The drive assembly of the present invention includes opposed housing parts that are adapted to mount or seat a hub element, a slider element, and a drive arm. The hub element is adapted to operate in connection with a manual operating element, such as a latch element of a deadbolt, to move the locking elements between the locked and unlocked positions. The drive arm includes a drive interface pin that is adapted to seat within a connector portion that is mounted within a chamber or cavity formed in at least one of the locking elements. The movable locking elements can include any selected number of locking elements, and preferably have a wedge-like shape.
The door latch assembly of the present invention has opposed housing parts that are adapted to house and seat a latch hub, a latch arm, and a biasing element.

According to still another practice, the present invention is directed to a door lock assembly for use with a door, comprising a movable locking assembly disposed within a recess formed in an edge of a door panel having one or more movable wedge shaped locking elements disposable between a locked position and an unlocked position, a drive assembly operatively coupled to the movable locking assembly for moving the movable locking elements between the locked and unlocked positions, and a latch assembly configured for coupling the door to a door frame and operable independently of the movable locking assembly.
These and other features and advantages of the present invention will be more fully understood by reference to the following detailed description in conjunction with the attached drawings in which like reference numerals refer to like elements throughout the different views. The drawings illustrate principals of the invention and, although not to scale, show relative dimensions.
The present invention is directed towards a frame based door lock assembly or system that can lock, seal and secure an entrance to a dwelling. The door lock assembly of the present invention is formed and mounted within a door frame and has a movable locking element that, when deployed, locks and seals the door to the frame. As used herein, the term “dwelling” is intended to include any partially or fully enclosed space that requires a door, such as a residential or commercial structure. Examples of dwellings contemplated by the present invention include houses.
The present invention is also directed towards a door panel based door lock assembly or system that can also lock, seal and secure an entrance to a dwelling. The door lock assembly of the present invention is formed and mounted within a door panel and has a movable locking element that, when deployed, locks and seals the door to the frame.
The present invention is also directed towards a system and method for a user to register the door lock assembly and to control and manage the state and access rights of the door lock assembly of the present invention.
As shown in
The illustrated frame element 26 includes a relatively flat portion 27 having a front surface and a back surface. The front surface of the frame element has formed thereon a number of surface features or protrusions. Specifically, the front surface of the frame element includes a channel housing 29 that forms a channel 28 therein. The channel is sized for accommodating any suitable wiring that needs to run along the door jamb. For example, according to one embodiment, the channel accommodates power conduits that connect at one end to the control panel and at the other end to a suitable power source. Examples of suitable power sources include door bell wiring and the like. The power conduits can include any suitable wiring or cable, such as electrical wiring, Ethernet cables and the like.
The front surface of the flat portion 27 of the frame also includes an integrally formed outwardly projecting lock connector portion 30 that includes a relatively flat extension 30A that has integrally formed therewith a curved connector element 30B that forms a lock receiving groove 30C. The lock receiving groove 30C is adapted to seat and mount a portion of the movable locking element 90 (
With reference to
As shown in
The control panel 22 includes a motor 32 for providing the power necessary to actuate the door locking assembly. The motor 32 includes a cam 34 that mounts to a shaft 33 of the motor. The cam is formed as an eccentric member that has a flanged end with a pin receiving aperture formed therein. The cam 34 is in turn coupled to a drive plate 40 via a cam pin 38 that serves to directly connect the plate to the cam. The cam when rotated by the motor shaft moves in a reciprocating manner, and this reciprocating motion is transferred to the drive plate 40. The shape of the cam element helps limit or define the axial movement of the drive plate 40.
The illustrated drive plate 40 includes, when viewed from the front, a substantially vertically disposed and axially extending lock connector portion 42 and an integrally formed, substantially horizontally disposed and axially extending cam connector portion 44. According to one embodiment, the lock connector portion 42 and the cam connector portion 44 are perpendicular relative to each other. The illustrated lock connector portion 42 includes a series of channels that allow for substantially linear movement of the drive plate when driving a locking element between the locked and unlocked positions, as explained below in further detail. Specifically, the drive plate 40 includes a first elongated channel 50 that is sized and configured for seating a fastener 62. The fastener is adapted to couple to a guide pin 72 for securing the drive plate to the frame element 26 of the lock assembly 20. The fastener 62 when mounted and seated within the channel 50 is adapted to travel within the channel upon movement of the drive plate, thus guiding the drive plate when moving in the axial direction A. The fastener thus operates to help secure the drive plate to the door frame while concomitantly ensuring that the drive plate moves or translates in a horizontal or axial direction (i.e., a direction perpendicular to the axis of the motor and the door frame).
The lock connector portion 42 of the drive plate 40 also includes a pair of parallel channels 52, 54 that are horizontally spaced in the axial direction from the channel 50. The channels 52 and 54 are also sized and configured for seating fasteners 64 and 66, respectively. The length of the channels 52, 54 are sized to allow translation of the drive plate in the axial direction without impeding movement thereof. The fasteners 64 and 66 threadingly engage with the guide pins 74 and 76, respectively, for also securing the drive plate to the frame element. The lock connector portion of the drive plate also includes a vertically extending groove 56 that seats an end portion of a drive pin 80. The drive plate at a terminal or axially outwardly most end terminates in a cut-out or groove. The groove 86 is sized and configured for seating a portion of a ramp assembly 100. Those of ordinary skill will readily recognize that the illustrated drive plate 40 can have any shape or configuration suitable for converting the rotational movement of the motor into linear movement of the plate, while concomitantly seating or mounting the required mechanical components.
As further illustrated in
The bottom portion 106 of the ramp member 102 includes a multi contoured top surface 126 and a multi-stepped bottom surface 128 that are bounded at each end by a flattened first terminal end 122 and a flattened second terminal end 124. The first terminal end 122 includes one or more fastener receiving apertures that are also adapted to seat the fasteners 138, and the opposed second terminal end 124 includes a flattened portion that has a tab engaging channel formed therein. The bottom surface 128 includes a series of steps that extend between the terminal ends and the step surface disposed adjacent the second terminal end 124 forms a drive plate engaging surface 132 sized and configured for seating within the groove 86 of the drive plate 40.
The multi contoured top surface 126 includes an initial flat surface 140 disposed adjacent the second terminal end 124 that transitions to a sloped surface 142 that has a rounded top portion that transitions to a detent groove 120 for seating a portion of the movable locking element when engaged therewith.
The bottom portion 106 and the top portion 104 of the ramp member 102 can be assembled together by inserting the tab portion 114 of the top portion of the ramp member into the tab engaging channel 130. When so assembled, the overlay portion 110 of the top portion overlies and mates with the first terminal end 122 of the bottom portion 106. When so assembled, the holes formed in the first ends of the top and bottom portion are aligned so as to receive the fasteners 138. The fasteners and the tab portion disposed in the channel 130 help secure the top and bottom portions of the ramp member together.
The illustrated door lock assembly also includes a pivot mechanism 150. The pivot mechanism 150 includes an aperture 156 formed at one end. The pivot mechanism is secured to the frame by way of fastener 152 that passes through the aperture 156 and seats within the guide pin 154. The guide pin in turn is secured to the frame element 26. A pair of drive pins 80, 158 can also be coupled to the pivot mechanism. The first drive pin 80 seats within a corresponding aperture formed in a bottom portion of the pivot mechanism and is sized and configured for seating in the U-shaped channel 56 of the drive plate. The second drive pin 158 seats within an aperture formed in a top portion, and specifically, an extension portion, of the pivot mechanism and is sized for seating in a channel 174 formed on a rear surface of a manual control element 170.
With reference to
The illustrated manual control element 170 also includes a guide portion 180 and a flange 182 extending outwardly the back surface 176B of the latch portion 176. The guide portion 180 includes a pair of substantially parallel channels 184, 186. The inner channel 184 has an overall length that is smaller than the length of the outer channel 186, and the inner channel 184 is offset from the outer channel 186 in the longitudinal direction of the guide portion. The inner channel 184 is adapted to seat a fastener 188 that is coupled to a guide pin 190 disposed on the opposed side of the channel. The outer channel 186 is adapted to seat a pair of fasteners 192, each of which is coupled to a guide pin 194. Similar to the other guide pins, the guide pins 190, 194 secure selected elements of the door lock assembly to the frame element.
As shown in
In operation, when the door lock assembly is fully assembled and integrated within the door frame, the movable locking element 90 can be moved between an unlocked position where the element is stored within the frame and specifically within the groove 92, and a locked position where the movable locking element is moved pivotably outwardly from the groove 92 so as to seat within a channel formed in a side of the door panel. With reference to the foregoing Figures, and with particular reference to
When the unit is not actuated, the lock can be disposed for example in the unlocked position (
When the unit is actuated, as shown in
When the locking element 90 contacts the engaging portion 204 of the sealing element 202, the locking element forms a strong sealing and locking connection. Indeed, any additional force applied to the door panel from an outside surface or side enhances and strengthens the sealing contact between the locking element 90 and the sealing element 202.
Those of ordinary skill will readily recognize that the battery 58 housed within the door lock assembly 20 can power one or more of the other components of the assembly either directly or indirectly. The battery can be charged during periods of non-use by a power source, such as through any local electrical connection.
The control panel 22 which forms part of an overall control box can be formed as a modular component. As such, if the control box needs to be replaced, the old box can be disconnected or removed from the frame and a new box can be installed. Hence, the control box is a removable and replaceable component of the door lock assembly 20.
Another feature of the present invention is that the door lock assembly 20 can be constructed so that the motor drives the drive plate, cam and hence locking element into the locked or unlocked position to provide a final sealing function, if moved into the locked position, or a final stowing function if moved into the unlocked position.
In further operation, the door lock assembly may be controlled by a suitably programmed computing device. In one exemplary embodiment, the computing device may be a mobile computing device such as a cell phone, smart phone, watch, tablet computer, or customized device such as a fob, or any other suitable electronic device. The computing device may include a wireless transmitter, such as a radio antenna, for wirelessly communicating with the lock. It should be noted that the lock may be controlled by any alternative means which include a method for identifying a user, such as by entering a user-assigned pin number on a keypad, or biometric authentication (e.g., using a fingerprint, facial recognition, voice commands, or other means), among other possibilities.
The computing device may be programmed to set up and manage a door lock assembly at one or more access points in a dwelling or other secured area, which may include identifying the specific lock, designating an owner or administrator for the lock, and registering users who have rights to perform actions with respect to the lock. Such actions may include locking or unlocking the door lock assembly, viewing the current status of the lock (e.g., “locked” or “unlocked”), accessing a camera associated with the lock, viewing a log of when the lock's status was changed, etc. Furthermore, such actions may include administrative actions, such as recognizing and registering a new lock, inviting users to have access rights to the lock, restricting users from using the lock and/or limiting access rights for existing users of the lock.
Actions and rights may be applied to a particular door lock assembly, or may be applied together to a group of locks organized into common locations (e.g., the “My House” location may have a Front Door lock, a Back Door lock, and a Garage Door lock). Similarly, individual users may be managed using the computing device, or users may be grouped together and managed as a group.
Access and/or administrative rights over locks may be restricted to certain times for particular users. For example, a user may be assigned “guest” access rights which last for a specified period of time (e.g., one week) or until a specified time (e.g., until April 1 at 6:00 PM).
Exemplary interfaces for setting up and administering a lock and managing users of the lock are described below, with reference to
In order to gain rights to access and manage locks, a user may first register an account, as shown in the exemplary account registration interface 300 of
The account registration interface 300 may include an identification dialog 302 for entering an identifier, such as a name. The identifier may be, for example, an alphanumeric string. The identifier may be used to identify the account associated with the user.
The account registration interface 300 may further include a code entry 304 for entering a secret or non-public code associated with the user's account. The code may be required in order to take actions related to the account, such as changing the status of a lock to which the account has access rights and/or administering a lock (e.g., adding guest users to the lock). The code may be selected by the user, or may be assigned by the registration software (e.g., by choosing a random number). The pin may be, for example, alphanumerical or strictly numerical.
Optionally, the account registration interface 300 may include a remote administration option 306. The remote administration option may allow the user's account settings to be stored in a remote location, such as a centralized server. This option allows for account recovery, in case the user's account information is accidentally deleted from the local actuation or mobile device. Furthermore, by saving the user's account information remotely, the user can access the account from a device that is different than the actuation device on which the original account registration was completed.
In one embodiment, no account or lock information is saved remotely. Rather, the account and lock information resides solely on the user actuation devices and the locks themselves. For example, the lock may be provided with a non-transitory storage medium which is in physical contact or short range wireless communication (e.g., less than 100′, or as determined by typical ranges associated with a short-range wireless protocol such as a typical WiFi transmitter or Bluetooth® transmitter) with the locking mechanism. Thus, all the “keys” associated with the lock may be stored securely in the locking mechanism itself. In this way, there is no central storage location which could be compromised, thereby also compromising all the locks and user accounts stored in the central storage location. Hence, the actuation or mobile device operates or functions as a universal key since it can be programmed to open any particular lock in any particular dwelling. As such, the actuation device can be deemed to be an identity based device since it is associated with the user and whether that user has permission to enter a specific dwelling rather than a lock specific device.
When a user wishes to register a new lock so that the lock may be managed, the user may perform an initial setup procedure for the lock using registration software, as shown in
The lock and/or registration software may be provided with authentication capabilities to ensure that only an authorized user sets up the lock. For example, the lock may be configured to respond only to a handshake from a predetermined setup account. Upon purchasing the lock, the user may be provided with information allowing the user to access the predetermined setup account (e.g., an access code unique to the lock which, when entered into the registration software, allows the registration software to communicate with the lock), and thereby set up the lock.
Once the registration software has successfully connected to the lock, the interface 308 may be updated so that the status bar indicates the identity of the lock, as shown in
Upon selecting the interface configuration element 312, a configuration interface 314 may be presented for configuring basic information about the lock, as depicted in
Multiple door lock assemblies may be associated with a particular location, such as by assigning the locks a common location identifier. In one embodiment, locks with a common location identifier may be administered and/or accessed together as a group or a single entity. For example, if a user is given access rights to lock/unlock a particular location (e.g., “John's House”), then the user may lock or unlock any and/or all locks associated with the location (e.g., “John's Front Door” or “John's Back Door”).
A graphic identification element 318 may be provided for allowing a user to create or select a graphic representing the lock. For example, the graphic identification element 318 may present an option to select an existing photograph, such as a photograph stored on the user's mobile phone or on a remote server, to represent the lock. Alternatively or in addition, if the registration software detects that it is running on a device (such as a mobile phone) that is equipped with a camera, the graphic identification element 318 may prompt the user to take a picture of the lock or the fixture in which the lock is installed (e.g., a door, garage door, window, etc.). The picture may be used to identify the lock. Alternatively or in addition, the registration software may be provided with preconfigured graphics that may be used to represent the lock. Upon selecting the graphic identification element 318, the user may be presented with the preconfigured graphics and prompted to select a preconfigured graphic to represent the lock.
Upon selecting or creating a graphic to represent the lock, an editing interface 320 may optionally be presented, as shown in
After the lock is set up, the registration software may prompt the user to define an administrator for the lock in an administrator interface 322, as depicted in
The administrator may be a permanent administrator, or a temporary administrator may be defined. The administrator interface may include a timeline configuration tool with a starting input 324 and an ending input 326. The starting input 324 and the ending input 326 may be used to identify, respectively, when the administrator's term as an administrator begins and ends. A permanent administrator may be established by setting, for example, the starting input 324 to “immediately” and the ending input 326 to “never.” A temporary administrator may be established by setting specific starting and ending times defining the temporary administrator's term. If a temporary administrator is established and the temporary administrator's term expires without providing a new administrator, then the temporary administrator may be prompted to select a new administrator.
When an administrator is removed from a lock, the lock may optionally be placed into escrow. This may be particularly applicable when a property such as a house is sold and administration of the locks on the house is passed to a new owner. Secure ownership of locks associated with a particular location may be transferred to a third party, such as an escrow company. When ownership of the property is transferred to a new owner, the escrow company may transfer ownership and administration privileges for the locks to the new owner as well.
Similarly, if a transfer is made directly from the old owner to the new owner, the old owner may securely relinquish access rights directly to the new owner by specifying that the new owner should become an administrator on a certain date, and by specifying that the old owner's administration privileges expire on that date.
Alternatively, the old owner may relinquish administration privileges without specifying a new administrator. In this case, the lock may return to a factory-default setting and await a claim by an owner with the lock's original predetermined setup information. In another embodiment, the old owner may specify a code that, when entered by the new owner, causes ownership and/or administration privileges of the lock or locks at a particular location to pass to the new owner.
In the above-described embodiments, a user device such as a mobile phone may be configured to function with (e.g., administer or access) a lock by registering the lock with a user account associated with the user device. It should be noted that multiple user devices may be registered with the user account.
For example, if a user account is initially set up on a mobile device such as a phone, the user may also authorize a custom fob to work with the user account. The mobile device may take ownership of the fob by programming the fob with a group ID or location ID associated with a location (e.g., a group of locks that are related to each other or in proximity to each other, such as locks on a particular house), or an account ID associated with the user account. A device ID and/or token associated with the fob may similarly be added to the user account (e.g., in a database or data structure on the mobile device or a central server which stores registration information for user accounts). Any number of hardware devices and/or access methods may be associated with a user account.
In a similar manner, a hardware device that is associated with a user account may be removed from the user account and/or associated with a different user account. Thus, ownership of the hardware device may be securely transferred between users.
Alternatively or in addition to the above registration procedures, a user who initially does not have access rights to access a particular lock may request such access rights.
The lock may be a private lock associated with one or more owners, as noted above, or may be a common, public, or shared lock which may be accessible by a user if the user meets certain criteria. For example, a restroom may have a lock that is only accessible by users of the appropriate gender. In some cases, any member of the public may request access to the public lock, while in other cases access to the lock may be restricted (e.g., an employees' restroom may be accessible only to people who work at a particular company).
The user may approach the lock with a mobile device, fob, or other device and place both the lock and the device into a pairing mode. This may be accomplished in a single action, for instance by tapping the device to the lock. Alternatively, the lock and device may be separately placed into pairing mode by issuing commands to the lock and/or device.
The lock and device may attempt to pair with each other and, if successful, the lock and/or device may identify that the device is not authorized to access the lock. Accordingly, a message may be displayed to the user on the device indicating that the user does not have access to the lock, and querying whether the user would like to request access. The device may accept the user's request to access the lock.
If the lock is a private lock, the request may be transmitted to one or more owners of the lock, who may then approve or deny the request. If the request is approved, the user may be provided with the necessary privileges to access the lock, as described in more detail below. Alternatively or in addition, the owner may simply be notified that the user is waiting at the lock (e.g., through a bell or chime similar to a doorbell), in which case the owner may remotely unlock the door. In another embodiment, tapping an unauthorized device to the lock may cause the device to initiate a telephone call or video chat with the owner of the lock.
If the lock is a public lock, an interface may be presented for entering information about the user of the device. The information may include identifying information, such as a name and/or a phone number, and/or may be descriptive. The descriptive information may be used to determine whether the user is permitted to access the lock. In the example above regarding the restroom, the user may be queried as to whether they are male or female. Once the information is entered, the lock, device, and/or a remote server may determine, based on the user's responses, the user is authorized to access the lock. The lock may store records, including the entered information and/or a timestamp, relating to attempts to access the lock by the electronic device. In this way, a history of which users entered the room secured by the lock may be maintained.
In some situations, the user may be requested to provide authenticating information to determine whether the user is permitted to access the lock. For example, if the lock secures an employees' restroom as in the example above, the user may be asked to provide their employee ID number, login password, or another identifier.
Accordingly, users without access to a private or public lock may request that they be granted access to the lock.
After initial setup, users with appropriate access rights to the lock may manage the state of the lock through a suitable interface. For example,
The management interface 328 may include a selection mechanism 330 for choosing a particular lock associated with the user's account. In the exemplary management interface 328, two locks are associated with the user account, as indicated by the two dots in the center/top of the display, and the selection mechanism allows for a selection of one of the two locks to be made. Identification indicia 332 provides general information about the currently-selected lock, such as a name and/or address of the lock and a graphic representing the lock.
A locking mechanism 334, such as a button or a slider, may be presented for changing the status of the lock (e.g., to “locked” or “unlocked”). The locking mechanism 334 may display the current status of the lock, or the current status may be displayed separately from the locking mechanism 334.
Upon activating the locking mechanism 334, a signal may be sent to a processing device associated with the lock, which actuates the lock to change the lock's status to reflect the user's selection. In exemplary embodiments, the user device may communicate with the lock through a wireless signal, such as a Bluetooth® signal. The user device may be pre-paired with the lock or otherwise preauthorized to use the lock so that the user device can simply transmit a “lock” or “unlock” signal without the requirement of discovering the lock and performing initial setup when the lock is first encountered.
In one embodiment, the lock may communicate with user devices through a courier that connects the lock to a secure remote server. Accordingly, user devices may not communicate with the lock except through a secure connection. In other embodiments, the lock may communicate directly with user devices using a secure protocol.
Upon receiving a lock or unlock signal, the lock may automatically take action to actuate the internal locking mechanism (as described in detail above), thereby locking or unlocking the lock.
A log of actions taken with respect to the lock may be maintained and viewed by certain users who have the right to access the log. For example, every time the lock is unlocked or locked, the time and user who initiated the action may be noted in the log. When additional users are given rights to the lock or when existing users are restricted from using the lock or have access rights restricted, such administrative changes may also be noted in the log. The log may be stored on a computing device associated with an administrator of the lock, at a central location connected to the lock and/or users of the lock through a network, or on the lock itself.
The management interface 328 may include a log summary 336 describing the most recent action take with respect to the lock. For example, the log summary 336 may display the last time the lock's status was changed, what the status was changed to, and which user changed the status. This information may be retrieved from the log if the user has sufficient privileges to view the information in the log. If the user does not have sufficient access rights to view the log, then the registration software may abstain from displaying the log summary 336.
A user with administrator rights to a lock may invite additional users to have access rights to the lock. For example,
The registration software may access a contacts list 338 of the administrator, as shown in
Upon selecting a user 340, the administrator may be presented with a user administration interface 342, as shown in
An access rights level selector 346 may be provided to assign different sets of access rights to the user. For example, a user who is designated is a “guest” may have rights to change the status of a lock (e.g., to lock or unlock the door lock assembly). A user who is designated as an “administrator” may be permitted to invite other users to have access rights over the lock.
A temporal limitation selector 348 may allow the administrator to define a time period for which the invited user is permitted to access or administer the lock. The user may be given permanent rights to the lock by assigning a start time of “immediately” and an end time of “never.” Alternatively, the user may be given temporary rights by defining a particular time frame in which the user is permitted to access the lock.
Upon selecting a user and configuring the user's rights with respect to the lock, an invitation may be generated and transmitted to the user. For example, the invitation may be sent to a mobile device defined by an identifier associated with the user in the contacts list 338 (e.g., a phone number or an email address).
When the invitation is sent to the user, the user may be presented with an invitation interface 350, as depicted in
If the invitation is accepted, the lock may be added to the user's account. For example, the user's mobile device or fob may include a non-transitory storage medium storing one or more tokens, where each token represents a lock or group of locks to which the user has access rights.
In one embodiment, locks may be represented on a client-side storage medium as participants in a “chat room.” One or more chat rooms on the client device may represent locations to which the client has access rights (e.g., “My House”). Within the chat room, one or more locks may be represented as participants (e.g., in the “My House” chat room, participants may include “My Garage,” “My Front Door,” “My Back Door,” etc.). When approaching a particular location defined by a chat room (as determined, e.g., by GPS coordinates), the members of the chat room may be determined and any requisite setup may be performed (e.g., pre-pairing the user device with the lock, as described in more detail below) so that the user can simply approach the lock and request that the lock be opened.
Thus, details about which locks a user has access to may be stored directly on the user's device, thereby turning a single “key” (i.e., the user's device) into an access mechanism opening any lock to which the user has rights. Instead of the conventional technique where a key provides access to a single lock, in exemplary embodiments of the present invention a key is tied to a user's identity and may open any lock to which the user has been assigned access rights.
The lock may be pre-paired with the user's device so that the user will be able to immediately change the status of the lock without the need to search for, discover, and/or initially pair with the lock. For example, the invitation may include pairing information for the lock (such as an identifier, access code, protocol, and/or frequency which may be used to communicate with the lock) so that the user's device may be preconfigured with sufficient information to allow the user's device to communicate with the lock immediately. In this manner, the user device may be preauthorized to communicate with the lock.
A user with sufficient rights may be presented with administrative details regarding the lock. For example,
The administrative details may include options 362 for enabling auto-locking and auto-unlocking of the door lock assembly. When auto-locking or auto-unlocking is enabled, the status of the lock may be changed based on the proximity of the user's device to the lock. When the user's device approaches to within a predetermined distance of a door panel of the dwelling or enclosure where the door lock assembly is disposed in the locked position, the lock may detect the presence of the user's device and automatically move the lock into the unlocked position. The presence of the user's device may be determined, for example, by using a predetermined wireless signal such as a Bluetooth® signal or a Wi-Fi signal. The distance to the device may be determined, among other options, using a Global Positioning System (GPS) signal, triangulation with cellular towers or other wireless transmitters/receivers.
Furthermore, the administrative details may include a list 364 of users who have access rights (as administrators and/or as guests) to the door lock assembly. Using the list 364, the user accessing the administrative interface 358 may access a profile of the selected user to determine what rights the user has with respect to the identified lock 360. If the user accessing the administrative interface 358 has sufficient rights, the user may be presented with a removal option 366 to remove all access rights from a selected user in the list 364.
Thus, a user with administrator privileges may remove a user's registration from a particular lock, thereby eliminating the removed user's rights to access the lock. Alternatively, a user may remain registered with the lock, but their rights may be modified (e.g., by adding or removing administrator privileges from the user, by changing a temporary guest user into a permanent user, or by changing a permanent user into a temporary guest user, among other possibilities).
A user may also wish to determine whether they have access rights in a particular lock. Accordingly, a user may search for existing locks in order to (for example) request access to the lock from the lock's owner or identify the presence or level of access rights that the user has with respect to a particular lock.
A lock administrator may choose to have their lock appear in search results, or not appear in search results. In one embodiment, locks may appear in a user's search results only if the lock is administered by a person in the user's contact list (e.g., on the user's mobile phone).
One or more of the above-described acts may be encoded as computer-executable instructions executable by processing logic. The computer-executable instructions may be stored on one or more non-transitory computer readable media. One or more of the above described acts may be performed in a suitably-programmed electronic device.

A virtual machine 405 may be provided to handle a process running on multiple processors so that the process may appear to be using only one computing resource rather than multiple computing resources. Virtualization may be employed in the electronic device 400 so that infrastructure and resources in the electronic device may be shared dynamically. Multiple VMs 405 may be resident on a single computing device 400.
A hardware accelerator 406 may be implemented in an ASIC, FPGA, or some other device. The hardware accelerator 406 may be used to reduce the general processing time of the electronic device 400.

The information may be executed, interpreted, manipulated, and/or otherwise processed by the processor 402. The storage device 416 may include, for example, a storage device, such as a magnetic disk, optical disk (e.g., CD-ROM, DVD player), random-access memory (RAM) disk, tape unit, and/or flash drive. The information may be stored on one or more non-transient tangible computer-readable media contained in the storage device.

Alternatively, the chat room 426 may identify a user, and furthermore identify all of the locks to which the user associated with the user account 424 has access rights.
One or more embodiments of the invention may be implemented using computer-executable instructions and/or data that may be embodied on one or more non-transitory tangible computer-readable mediums. The mediums may be, but are not limited to, a hard disk, a compact disc, a digital versatile disc, a flash memory card, a Programmable Read Only Memory (PROM), a Random Access Memory (RAM), a Read Only Memory (ROM), Magnetoresistive Random Access Memory (MRAM), a magnetic tape, or other computer-readable media.
The network 430 may transport data from a source to a destination. Embodiments of the network 430 may use network devices, such as routers, switches, firewalls, and/or servers (not shown) and connections (e.g., links) to transport data. Data may refer to any type of machine-readable information having substantially any format that may be adapted for use in one or more networks and/or with one or more devices (e.g., the computing device 400, the service provider 432, etc.). Data may include digital information or analog information. Data may further be packetized and/or non-packetized.
The network 430 may be a hardwired network using wired conductors and/or optical fibers and/or may be a wireless network using free-space optical, radio frequency (RF), and/or acoustic transmission paths. In one implementation, the network 430 may be a substantially open public network, such as the Internet. In another implementation, the network 430 may be a more restricted network, such as a corporate virtual network. The network 2012 may include Internet, intranet, Local Area Network (LAN), Wide Area Network (WAN), Metropolitan Area Network (MAN), wireless network (e.g., using IEEE 802.11), or other type of network The network 2012 may use middleware, such as Common Object Request Broker Architecture (CORBA) or Distributed Component Object Model (DCOM). Implementations of networks and/or devices operating on networks described herein are not limited to, for example, any particular data type, protocol, and/or architecture/configuration.
The service provider 432 may include a device that makes a service available to another device. For example, the service provider 432 may include an entity (e.g., an individual, a corporation, an educational institution, a government agency, etc.) that provides one or more services to a destination using a server and/or other devices. Services may include instructions that are executed by a destination to perform an operation (e.g., an optimization operation). Alternatively, a service may include instructions that are executed on behalf of a destination to perform an operation on the destination's behalf.
The server 434 may include a device that receives information over the network 430. For example, the server 434 may be a device that receives user input from the computer 400. The cluster 436 may include a number of units of execution (UEs) 438 and may perform processing on behalf of the computer 400 and/or another device, such as the service provider 432 or server 434. For example, the cluster 436 may perform parallel processing on an operation received from the computer 400. The cluster 436 may include UEs 438 that reside on a single device or chip or that reside on a number of devices or chips.
The units of execution (UEs) 438 may include processing devices that perform operations on behalf of a device, such as a requesting device. A UE may be a microprocessor, field programmable gate array (FPGA), and/or another type of processing device. UE 438 may include code, such as code for an operating environment. For example, a UE may run a portion of an operating environment that pertains to parallel processing activities. The service provider 432 may operate the cluster 436 and may provide interactive optimization capabilities to the computer 400 on a subscription basis (e.g., via a web service).
Units of Execution (UEs) may provide remote/distributed processing capabilities for the applications 420. A hardware unit of execution may include a device (e.g., a hardware resource) that may perform and/or participate in parallel programming activities. For example, a hardware unit of execution may perform and/or participate in parallel programming activities in response to a request and/or a task it has received (e.g., received directly or via a proxy). A hardware unit of execution may perform and/or participate in substantially any type of parallel programming (e.g., task, data, stream processing, etc.) using one or more devices. For example, a hardware unit of execution may include a single processing device that includes multiple cores or a number of processors. A hardware unit of execution may also be a programmable device, such as a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), a digital signal processor (DSP), or other programmable device. Devices used in a hardware unit of execution may be arranged in many different configurations (or topologies), such as a grid, ring, star, or other configuration. A hardware unit of execution may support one or more threads (or processes) when performing processing operations.
A software unit of execution may include a software resource (e.g., a technical computing environment) that may perform and/or participate in one or more parallel programming activities. A software unit of execution may perform and/or participate in one or more parallel programming activities in response to a receipt of a program and/or one or more portions of the program. A software unit of execution may perform and/or participate in different types of parallel programming using one or more hardware units of execution. A software unit of execution may support one or more threads and/or processes when performing processing operations.
The term ‘parallel programming’ may be understood to include multiple types of parallel programming, e.g. task parallel programming, data parallel programming, and stream parallel programming. Parallel programming may include various types of processing that may be distributed across multiple resources (e.g., software units of execution, hardware units of execution, processors, microprocessors, clusters, labs) and may be performed at the same time.
For example, parallel programming may include task parallel programming where a number of tasks may be processed at the same time on a number of software units of execution. In task parallel programming, a task may be processed independently of other tasks executing, for example, at the same time.
Parallel programming may include data parallel programming, where data (e.g., a data set) may be parsed into a number of portions that may be executed in parallel using, for example, software units of execution. In data parallel programming, the software units of execution and/or the data portions may communicate with each other as processing progresses.
Parallel programming may include stream parallel programming (sometimes referred to as pipeline parallel programming). Stream parallel programming may use a number of software units of execution arranged, for example, in series (e.g., a line) where a first software unit of execution may produce a first result that may be fed to a second software unit of execution that may produce a second result given the first result. Stream parallel programming may also include a state where task allocation may be expressed in a directed acyclic graph (DAG) or a cyclic graph.
Other parallel programming techniques may involve some combination of task, data, and/or stream parallel programming techniques alone or with other types of processing techniques to form hybrid-parallel programming techniques.
The foregoing description may provide illustration and description of various embodiments of the invention, but is not intended to be exhaustive or to limit the invention to the precise form disclosed. Modifications and variations may be possible in light of the above teachings or may be acquired from practice of the invention. For example, while a series of acts has been described above, the order of the acts may be modified in other implementations consistent with the principles of the invention. Further, non-dependent acts may be performed in parallel.
In addition, one or more implementations consistent with principles of the invention may be implemented using one or more devices and/or configurations other than those illustrated in the Figures and described in the Specification without departing from the spirit of the invention. One or more devices and/or components may be added and/or removed from the implementations of the figures depending on specific deployments and/or applications. Also, one or more disclosed implementations may not be limited to a specific combination of hardware.
Furthermore, certain portions of the invention may be implemented as logic that may perform one or more functions. This logic may include hardware, such as hardwired logic, an application-specific integrated circuit, a field programmable gate array, a microprocessor, software, or a combination of hardware and software.
No element, act, or instruction used in the description of the invention should be construed critical or essential to the invention unless explicitly described as such. As used herein, the article “a” is intended to include one or more items. Where only one item is intended, the term “a single” or similar language is used. Further, the phrase “based on,” as used herein is intended to mean “based, at least in part, on” unless explicitly stated otherwise. In addition, the term “user”, as used herein, is intended to be broadly interpreted to include, for example, an electronic device (e.g., a workstation) or a user of an electronic device, unless otherwise stated.
Similarly, a channel or groove 504 is formed within the door jamb of the door frame 10. A frame element 550 is mounted or seated within the channel 504 and is secured therein according to known techniques. For example, the frame element can be secured therein by fasteners, by an adhesive, or by known pressure fit techniques.
The door panel 18 can also have one or more holes or apertures 505, 507 formed therein for mounting for example a door handle or latch assembly 600 and a deadbolt assembly 570. The door panel apertures can be formed therein by a user or other skilled professional or can be pre-drilled by the manufacturer. As shown in
As illustrated in
Those of ordinary skill in the art will readily recognize that the frame element 510 can have any suitable shape or configuration, provided that the shape is suitable for its intended purpose. The illustrated frame element 510 can be made of any suitable material, and is preferably made of aluminum.
With reference to
The opposed end or an intermediate portion of the main body 524 of the locking element 522 has a groove 586 formed therein that is adapted to mount a resilient member 528. The resilient member 528 provides a sound dampening function during operation of the door lock assembly. Specifically, the resilient member 528 is adapted to contact one leg portion 515 of the frame element when the locking assembly is disposed in the locked or protruding position, as shown in
The main body 524 of the illustrated locking element 522 has opposed ends, the first end of which, as set forth above, includes the connecting portion 526 and the opposed second end wraps around to form in essence a hollow passage 590. The actuator of the deadbolt assembly described below is positioned in part within this passage during operation. The main body of the locking element also includes a notch or cut-out portion 588. The notch allows the locking element, when assembled to the frame element 510 mounted in the door panel, to seat about the actuator of the deadbolt assembly.
The illustrated locking element 522 can have any selected size and shape, provided that the locking element is capable of contacting the frame element 550 of the door frame in order to lock or secure the door panel 18 to the frame 10. The locking element 522 can be any suitable rail-type locking element that is capable of moving when actuated between the locked and unlocked positions. According to this embodiment, the locking element has a generally wedge-shaped configuration. The locking element can be made from any suitable material, and is preferably composed of aluminum. The resilient member can also have any selected size, shape or configuration, and can be composed of any suitable material, such as rubber.
The movable locking assembly 520 also includes an intermediate coupler element 530 and a drive element 540, as shown for example in
The illustrated drive element 540 also has a main body 541 that includes a central rectangular portion that has an elongated channel 542 formed therein. The drive element 540 has a first coupler receiving end 543 having a general cut-out portion 544 and a tab hole 545 that is sized and dimensioned for mounting over and engaging a respective end portion 534 of the intermediate coupler element 530. When coupled thereto, the end portion 543 of the drive element 540 seats over the boss 538 such that the tab 539 is positioned within the tab hole 545. This helps secure the drive element to the intermediate coupler element 530. The drive element 540 also includes a second opposed end 546 that extends outwardly from the main body and which has a partially formed channel or groove 547 formed thereon. The boss 537 formed on the end portion 533 of the intermediate coupler element 530 is coupled to one of the locking elements 522, and the second end of the drive element 546 when coupled to the end portion 534 of the intermediate coupler element 530 is coupled to the other locking element 522.
The drive element 540 helps constrain and trap an actuator mechanism, as described below, such that when the actuator moves the movable locking assembly into the locked position, it contacts and exerts a force on a portion of the drive element, such as the second end 546. The drive element in turn exerts a force on the locking elements 522 since they are coupled together. This in turn moves the locking elements into the locked position. Further, when the actuator mechanism moves the movable locking assembly 520 into the unlocked position, the actuator pulls back away from the drive mechanism and hence contacts (as shown in
The various elements of the movable locking assembly 520 as illustrated in the Figures and as described herein can be formed of any suitable material, and is preferably formed of aluminum.
As illustrated in
The door lock assembly 500 of the present invention also contemplates the use of an actuator mechanism for moving the locking assembly between the locked and unlocked positions. The actuator mechanism can optionally form part of the door lock assembly, although this element can also be separately provided, such as being formed for example as part of a deadbolt assembly. According to the current embodiment, the actuator mechanism can be a deadbolt assembly 570. As illustrated in
The illustrated deadbolt assembly 570 preferably includes within a chamber formed by the assembly housing a suitable actuation assembly that is capable of moving the actuator mechanism (e.g., piston 578). The present Figures simply illustrate for the sake of convenience and simplicity a general actuation assembly, which can include the actuation assembly of a conventional deadbolt which converts manual force applied by the user, such as via a latch or a key, into translational or linear movement of the piston (e.g., bolt or actuator). Alternatively, the actuation assembly can include any suitable arrangement of mechanical and electrical components that are capable of moving the piston. For example, the actuation assembly can include a motor that is powered by a battery or by electrical power supplied at the installation site to move the actuator. Examples of potential functionality and arrangement of components were described in some respects in connection with the first embodiment. Those of ordinary skill will readily recognize that for the purposes of the present invention it does not matter the type of actuation mechanism that is used provided that the mechanism is capable of moving the actuator (piston) linearly so as to properly interact with the locking elements 522, 522. As such, the actuator mechanism hence must be able to effect movement of the locking elements between the locked and unlocked positions.
As illustrated with reference to
Further, as illustrated in
The present invention also contemplates the use of a door latch assembly 600. The door latch assembly can, if desired, form part of the door lock assembly 500 of the present invention. The door latch assembly 600 is illustrated in
The illustrated door latch assembly 600 includes, in addition to the first and second main body portions, a latch piston element 610, a latch hub element 630, a piston actuator element 650, a biasing element 670, and a spring latch element 680. The latch piston element 610,
The latch piston element 610 is adapted to move in a linear direction as illustrated in
As illustrated in
A biasing element 670 is mounted about the boss 642 and is coupled thereto. The boss element this functions as a biasing element seat during use. The latch hub element 630 and associated biasing element are then mounted within the main body of the door latch assembly 600 such that the end of the biasing element opposite to the end coupled to the boss 642 contacts the inner surface 628A. The biasing element can be any suitable element sufficient for applying a biasing force to the latch piston element 610. According to a preferred embodiment, the biasing element is a spring.

As illustrated in
The door latch assembly 600 and associated components can have any selected shape or configuration, in addition to those illustrated and described herein. The various elements other than the biasing element can be formed from any suitable material, such as plastic.
The door latch assembly 600 of the present invention operates as follows. With reference to
If a user wishes to open the door, the user rotates the door handle (not shown), which applies a rotational force to the piston actuator element 650,
The operation of the door latch assembly 600 is separate and independent from operation of the movable locking assembly. Thus, the door latch assembly 600 can move the latch element between the engaged and retracted positions independent of the position of the locking assembly. Further, selected features of the first and second embodiments of the door lock assembly illustrated herein can be shared as would be apparent to one of ordinary skill in the art.
The elements of the door lock assembly 700 can be essentially the same as the elements disclosed in connection with the second embodiment of the invention unless otherwise noted below. As previously shown for example in
Similarly, a channel or groove 504 can also be formed within the door jamb of the door frame 10. A frame element 550 is mounted or seated within the channel 504 and is secured therein according to known techniques. For example, the frame element can be secured therein by fasteners, by an adhesive, or by known pressure fit techniques.
The door panel 18 can also have one or more holes or apertures 505, 507 formed therein for mounting for example a door handle or latch assembly and a deadbolt assembly. The door panel apertures can be formed therein by a user or other skilled professional or can be pre-drilled by the manufacturer. As shown in
As illustrated in
The movable locking assembly 520 of the present invention according to the current embodiment can also comprise a plurality of interconnected components. The illustrated assembly includes one or more, and preferably a pair, of movable locking elements 522, 522 that are adapted to pivot into and out of the space 518 formed by the frame element 510. Each of the movable locking elements 522 has a main body 524 that includes a connecting portion 526 formed at a first end. The connecting portion 526 is sized and dimensioned for seating within the groove 516B formed in the lock connector portion 516 of the frame element 510. The connecting portion 526 can have any suitable shape or configuration that allows the connecting portion to seat within and move relative to the lock connecting portion 516. According to one practice, the lock connector portion has a shape that is complementary to the shape of the groove 516B, and preferably has a substantially C-shaped configuration.
The opposed end or an intermediate portion of the main body 524 of the locking element 522 has a groove 586 formed therein that is adapted to mount a resilient member 528. The resilient member 528 provides a sound dampening function during operation of the door lock assembly. Specifically, the resilient member 528 is adapted to contact one leg portion 515 of the frame element when the locking assembly is disposed in the locked or protruding position, as shown in
The main body 524 of the illustrated locking element 522 has opposed ends, the first end of which, as set forth above, includes the connecting portion 526 and the opposed second end wraps around to form in essence a hollow passage 590. The actuator of the deadbolt assembly 720 described below is positioned in part within this passage during operation.
The main body 524 of the illustrated locking element 522 has opposed ends, the first end of which, as set forth above, includes the connecting portion 526 and the opposed second end wraps around to form in essence a hollow passage 590. The actuator of the deadbolt assembly described below is positioned in part within this passage during operation.
The illustrated locking element 522 can have any selected size and shape, provided that the locking element is capable of contacting the frame element 550 of the door frame in order to lock or secure the door panel 18 to the frame 10. The locking element 522 can be any suitable rail-type locking element that is capable of moving when actuated between the locked and unlocked positions. According to this embodiment, the locking element can have a generally wedge-shaped configuration. The locking element can be made from any suitable material, and is preferably composed of aluminum. The resilient member can also have any selected size, shape or configuration, and can be composed of any suitable material, such as rubber.
The movable locking assembly 520 can employ a connector portion 738 that is adapted to couple to the drive portion of the deadbolt or drive assembly 720. This connector 738 serves to matingly and operatively couple the deadbolt assembly to the movable locking assembly 520 so as to move the locking assembly between the locked and unlocked positions. Further, rather than employ an intermediate coupler element 530 and a drive element 540 as in the second embodiment, the movable locking assembly of this embodiment employs a wedge coupler element 880 that can be integrated with the latch assembly 810, as described in further detail below,
As shown in
The slider element 750 includes a main body 752 having a first end that is adapted to engage the hub portion 740. Specifically, the first end of the main body of the slider element has formed therein a groove 756 that is sized and dimensioned for receiving the latch element 746. The latch element when mounted within the groove serves to move the drive element assembly axially within the housing parts so as to move the lock assembly between the locked and unlocked positions. The first end also includes a pair of opposed tab portions 754 that are adapted to seat within a corresponding groove 732 formed in the housing parts 722, 724. The tab portions 754 are configured to axially move within the groove when the hub element is rotated.
The slider element 750 has a main body that includes an opposed second end that includes a hinge portion 760 that is configured to mate with, in a movable manner, an end of a drive arm 770. Specifically, the illustrated drive arm 770 includes a first end that has formed thereon a hinge portion 774 that is sized and dimensioned to mate with the hinge portion 760 of the slider element 750. The hinge portions can be interleaved together and then secured in this state by a hinge pin 792. The drive arm 770 has formed on an opposed second end a drive interface pin 778. The pin is adapted to be inserted into a connector portion 738 of the movable locking assembly. The main body of the drive arm 770 also includes an intermediate body portion disposed between the first and second ends and has an aperture 782 formed therein. The aperture is sized to seat an arm guide element or restrictor 790. The arm guide element can be mounted on either side of the drive arm within the aperture and is intended to restrict movement of the drive arm in that direction.
As shown in
The deadbolt assembly 720 of the present invention can be assembled as follows. The hinge portions of the slider element 750 and the drive arm 770 are assembled and secured together with the hinge pin 792 to form part of the drive assembly. The mated hinge portions allow the drive arm the ability to move in a curved or oscillating path with movement of the locking assembly 520 during use. The tab portions 754 of the slider element 750 are disposed in the grooves 732 of the housing parts 722, 724 and the second end of the drive arm 770 is disposed within the cut-out 728 of the head plate 726. The hub element 740 is then placed between the housing parts and the latch element 746 of the hub is disposed within the groove 756 of the first end of the slider element 750. The arm guide 790 is then disposed in the aperture 782 formed in the drive arm 770. If the door is a right swinging door then the arm guide is disposed in the aperture on a particular side of the drive arm (e.g., the side can be marked “R” if needed, which is the top surface of the drive arm illustrated in
When disposed in the unlocked position,
Conversely, when the user wishes to unlock the locked door, the latch of the deadbolt assembly is moved in the opposite direction. As such, the hub element drives the slider element and in turn the drive arm in the opposite axial or linear direction. When the drive mechanism moves the movable locking assembly 520 into the unlocked position from the locked position, the drive interface pin pulls on one or more of the movable connector elements via the connector portion 738 and hence moves the movable connector assembly from the deployed position into the stowed or retracted position.
The present invention also contemplates the use of a door latch assembly 810 suitable for use with the door lock assembly 700 according to the teachings of the present invention. The door latch assembly can, if desired, also form part of the door lock assembly 500. The door latch assembly 810 is illustrated for example in
The illustrated second main body housing portion 814 includes a head plate 822 that has a groove 824 formed therein. The groove is adapted to seat a portion of a latch arm 850. The head plate 822 also includes a hinge-like protrusion 828 which extends outwardly therefrom. The hinge-like protrusion is adapted to mate with a wedge coupler 880 and a latch element 900, as described below. The housing portion 814 also has formed therein at an end opposed to the head plate 822 an aperture 832 for seating a portion of a latch hub 840 and a latch or door handle (not shown) of a conventional handle assembly. The first main body housing portion 812 also includes at an end portion a similar aperture 834 for seating a portion of the latch hub 840. An inner surface of the housing portion 812 also has formed thereon a protruding seat element 836 that has formed on an end portion thereof a boss element 838. The boss element 838 is adapted to seat one end of the biasing element 870.
The illustrated door latch assembly 810 includes, in addition to the first and second main body housing portions, a latch hub 840, a latch arm 850, a biasing element 870, a wedge coupler 880, a latch element 900, and latch pin 920. As shown in
The biasing element 870 is mounted within the cavity 860 of the latch arm 850 and a first end is adapted to abut an inner wall 868 of the cavity 860 and the opposed end is adapted to seat about the boss element 838 of the housing portion 812. The boss element 838 thus functions as a biasing element seat during use. The biasing element 870 can be any suitable element sufficient for applying a biasing force to the latch piston element 864. According to a preferred embodiment, the biasing element is a spring.
The illustrated door latch assembly 810 also includes a wedge coupler 880. As shown in
With reference to
The deadbolt assembly 720 and the door latch assembly 810 and associated components can have any selected shape or configuration, in addition to those illustrated and described herein. The various elements other than the biasing element can be formed from any suitable material, such as plastic or metal or a combination of both.
As shown in the foregoing figures, and with particular reference to
The hinge portions of the head plate, wedge coupler 880 and latch 900 are assembled and the components are secured together by the hinge pin 920. When assembled together, the piston head 866 seats within the space 906 formed on the underside of the latch element 900. The mating together of the piston head 866 and the latch element 900 allows the latch arm 850 to move the latch element between selected positions, such as between an engaged or deployed position and a disengaged or retracted position. For purposes of explanation, a door handle (not shown) is deemed to be attached to the door latch assembly 810 via the central opening 844 formed in the latch hub 840 and the apertures 832, 834 formed in the housing portions 812, 814. When the door panel is closed relative to the frame, the latch element 900 is disposed in the normally disposed engaged position. In this position, the engagement portion 862 of the latch hub does not apply an axially inward force on the legs 854 of the latch arm 850. Consequently, no linear force is applied to the piston element 864 to counteract the force generated by the biasing element 870. As such, the biasing element pushes the latch piston element towards the head plate. This forward movement of the latch piston element linearly moves the piston head 866 in the same direction. The piston head 866 applies a force to the latch element 900 and since the piston head seats within the space 906, pivots the latch element into an engaged position. That is, the latch element extends outwardly from the main body of the door latch assembly 810 and seats within a channel or cavity 692 formed in the frame element 550. A strike plate, such as strike plate 694, is disposed about or adjacent to the cavity for helping ensure that the latch element seats within the cavity 692 during use. This disposes the door latch assembly 810 in the engaged position. In this position, the door is closed relative to the door frame.
If a user wishes to open the door, the user rotates the door handle (not shown), which applies a rotational force to the latch hub 840. The main body of the latch hub rotates and the engagement portion 846 engages the legs 854 of the latch arm and axially or linearly moves the latch arm in an inward linear direction, that is, in the direction opposite to the direction of the force that is applied by the biasing element 870. The engagement portion 846 converts rotational movement of the door handle and latch hub into linear movement of the latch arm 850. When this counter force exceeds the force applied by the biasing element, the latch arm moves inwardly thus compressing the biasing element. This linear movement forces the piston element 864 to move in the same direction, thus pivotably moving the latch element 900 in the same direction. This movement removes the latch element from the cavity 692, thus disengaging the door panel from the frame. This disposes the door latch assembly 810 in the retracted position. In this position, the door can be opened relative to the door frame.
The operation of the door latch assembly 810 is separate and independent from operation of the movable locking assembly. Thus, the door latch assembly 810 can move the latch element between the engaged and retracted positions independent of the position of the locking assembly. This feature is shown for example in
An advantage of employing a drive arm 770 that is hingedly or pivotably coupled to the slider element 750 is that the drive arm can better track the movement of the movable locking elements 522, which tend to move along a curved path (i.e., an arc). Further, the deadbolt assembly is compatible with both left and right swinging doors by simply switching the location of the arm guide 790. The arm guide serves to keep the drive arm aligned and at the proper location while concomitantly preventing movement of the drive arm in the incorrect direct while facilitating movement in the correct direction.
An advantage of the latch assembly 810 of the present invention is that the coupler element that coupled together the separate movable locking elements 522 forms part of the door latch assembly. When integrated as such, the door lock assembly 700 is easy to assemble. Moreover, integrating the wedge coupler 880 with the other components of the latch assembly 810 allows the door handle to be rotated even when the movable locking assembly is disposed in the locked position. Specifically, the latch element 900 of the latch assembly can move freely independent of the locking position of the movable locking assembly since the coupler element for coupling together the movable locking elements does not inadvertently interfere with movement of the latch element. Further, forming a hinge like joint between the latch arm 850, the wedge coupler 880 and the latch element 900 ensures that the elements pivot at the same location or along the same axis.
Those of ordinary skill in the art will readily recognize that the various components set forth above can have different shapes and configurations and can be formed of various well known materials. Those of ordinary skill will also recognize that the various components of the door lock assembly can be mounted within the door panel in a reverse manner.
It will thus be seen that the invention efficiently attains the objects set forth above, among those made apparent from the preceding description. Since certain changes may be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are to cover all generic and specific features of the invention described herein, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
