A latch assembly includes a rose, a handle rotatably coupled to the rose and rotatable around a rotation axis, and a latch. A biasing member is disposed within the rose and engaged with the latch. The biasing member being selectively connectable to the rose. When the biasing member is connected to the rose, the latch is pivotable around the rotation axis between a latched position and an unlatched position via the handle. The latch biased towards the latched position. When the biasing member is disconnected from the rose, the handle and the latch are rotatable together around the rotation axis between at least a left-handed configuration and a right-handed configuration. The biasing member connecting to the rose to secure the handle and the latch in either the left-handed configuration or the right-handed configuration.

A door knob assembly that provides an interactive visual and aural assembly familiar to a room occupant and that responds to variations in the manner of rotation of the knob in a plurality of responses, depending on the direction and rate of rotation applied to the knob, providing messages appropriate to the entertainment, safety and/or training of the knob operator and/or room occupant.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.

An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.

A sensor system to reliably alert and inform a user of the status of a window, in particular, a sensor system which reliably informs the user if the window is both in a closed position and also that the locking mechanism is in the locked configuration. There are thereby provided two independent sensor systems within the casement window handle assembly which are arranged to verify that the window handle is in the locked configuration and also that the window sash is in the closed position relative to the window frame. The casement window handle assembly comprises a first sensor for indicating the position of the window handle and this comprises a first sensor component mounted to the pivotal/movable handle and a second component fixed within the mounting base.

Door systems and door hardware components are described herein, along with methods of installing the door systems and components.

A handle operably coupled to rotating door handle assembly is disclosed. The handle may include a first rotatable member configured to engage a door latch mechanism. The handle may further include a second member mechanically engaged with the first member and the second member may be extended a length between a non-extended position and an extended position. A handle cavity may be defined within at least a portion of the second member and a bar may be enclosed within the handle cavity. Furthermore, an extension mechanism may be incorporated with the bar and the second member and configured to extend the bar from the cavity when the second member is in the extended position and retract the bar within the cavity when the second member is in the non-extended position.

A door locking device for a smart door apparatus (10) is provided comprising an interior door handle positionable on an interior side of a door; an exterior door handle positionable on an exterior side of the door (14); a lock for the door (14) which is coupled to the interior door handle, the lock having a deadbolt which is activatable by actuation of the interior door handle; a controller for automatically generating an alert signal in the event of activation of the deadbolt; and a wireless communication module associated with the controller, the wireless communication module automatically transmitting the alert signal in the event of activation of the deadbolt.
