Abstract: A lockset with a sliding spindle assembly allows ingress using a key on the outside or a button on the inside. The sliding spindle assembly provides first and second sliding mechanisms operated from the outside and inside, respectively, that operate a clutch to couple the outside handle to the main spindle. Each sliding mechanism comprises a key cylinder or twist and/or push button lock that rotates a cam to linearly advance (slide) a cam follower that incorporates a spindle receiver. The first sliding mechanism slides its spindle receiver between clutching and non-clutching positions with respect to the main spindle. The second sliding mechanism slides the main spindle itself between clutching and non-clutching positions with respect to the first sliding mechanism's spindle receiver. The sliding spindle assembly can be incorporated into a legacy lockset and also be used in a double-latch lockset.

Abstract: The standard spring retainer for a retract slide is upgraded in three embodiments. In the first embodiment, a first switch mounted on the upgraded spring holder is activated when the latch is retracted (from either side of the lock). In the second embodiment, the first switch is activated when either the latch is retracted or the latch bolt is pushed in by the latch hitting the strikeplate as the door is closing. A spring carrier/switch activator is added to the retract slide that is pushed back by the latch tailpiece. In the third embodiment, two switches monitor up to four conditions—when the door is open, closing, and closed and when the latch is being retracted by the inner or outer handle.

Abstract: A latchset comprises a latch cam hub configured to rotate on a door handle tailpiece, a first and optionally also a second projection extending radially outward from the hub, a sliding actuator comprising an elongated body and a first tooth, and a spring that resists retraction of the sliding actuator and urges the first projection against the first tooth. The latch cam is operative to retract the sliding actuator when a coupled door handle is rotated in only one rotational direction, such that rotation of the coupled door handle in the opposite rotational direction is inoperative to retract the sliding actuator. The hub is configured to be rotated by 90° during installation to set the latch cam to operate in an oppositely handed door. The latch cam prevents lost motion in eight door configurations.

Abstract: An integrated lock management and smart device control system comprises lock controllers configured to authenticate lock management system (LMS) credentials and also act as a hub for a collection of smart devices. The system also comprises a guest app that can receive and store an LMS credential or a functional derivative thereof and use the credential to unlock an entrance. The guest app also provides smart device controls. When these are selected, the guest app issues a command to the lock controller or an Internet gateway, backed by the LMS credential. After authenticating the LMS credential, the lock controller or gateway transmits a command to the smart device that is backed by a configurable smart device credential. Guest control of the smart devices is terminated by disabling the LMS credential.

Abstract: A lockset enables motion of an outside door handle in one direction to retract a latchbolt and motion of the outside door handle in an opposite direction to lock the deadbolt, and optionally also the latchbolt. The lockset then requires a key, code, or other credential to re-enter, unless another opens or unlocks the door from the inside. The ability to deadbolt the door from the outside makes it faster to secure a building or enclosure after exiting it.

Abstract: A double latch lockset, or its kit form, generally includes first and second retractable latches connected by a drive assembly. The first retractable latch may be activated by a first inside and/or outside actuator, and the second retractable latch may be activated by a second inside and/or outside actuator that activates the second retractable latch (such as a deadbolt) independently of the first retractable latch. Movement of the first inside and/or outside actuator in a first direction simultaneously retracts the first and second retractable latches, and movement of the first inside and/or outside actuator in a second direction locks the second retractable latch. The first inside and outside actuators may be configured to move in the second direction without retracting the first retractable latch.

Abstract: An electronic deadbolt operator for a deadbolt lockset comprises an electronic actuator that rotates a powered driver and a follower that has a lost motion connection with the powered driver, enabling the follower to rotate with the powered driver when the follower is inside its range of travel, and enabling the powered driver to rotate freely of the follower after the follower is pushed to a travel limit. The follower is mounted to a connector driver, which drives the deadbolt, to toggle between two oppositely-disposed off-center positions relative to the connector driver. In one off-center position, only clockwise rotation of the powered driver is operative to rotate the follower. In the opposite position, only counterclockwise rotation of the powered driver is operative to rotate the follower. The interaction between the powered driver, the follower, and stops causes the follower to toggle to an opposite position after hitting a stop.
