Abstract: A swinging door assembly includes a frame mount, a door panel, and a pivot assembly operably connecting the door panel to the frame mount such that the door panel is pivotable in two opposite directions from a closed position to first and second opened positions. When the door panel is pivoted in the first direction by an angle less than a threshold angle, or is pivoted in the second direction by an angle less than the threshold angle, the door panel is biased toward the closed position by virtue of a weight of the door panel, and when the door panel is pivoted in the first direction by an angle greater than or equal to the threshold angle, or is pivoted in the second direction by an angle greater than or equal to the threshold angle, the door panel is no longer biased toward the closed position.

Abstract: A door hardware assembly for a door having privacy and accessible sides includes a closing element moveable between a retracted position where the door is freely openable and an extended position where the door is maintained in a closed position when closed, and an actuator operably connected to the closing element, the actuator moving the closing element from the extended position to the retracted position upon receipt of an open command. At least one actuation sensor is provided on the privacy side of the door, causing the open command to be communicated to the actuator in response to an object being sensed within a threshold distance thereof, and at least one auxiliary sensor is provided on the privacy side of the door and providing at least one enhanced safety feature, the at least one auxiliary sensor being separate and distinct from the at least one actuation sensor.

Abstract: A lock assembly for a door includes a lock mechanism moveable between an extended position wherein the door is locked and a retracted position wherein the door is unlocked such that the door may be opened and closed. The lock assembly also includes first and second lock cylinders operably connected to the lock mechanism such that actuation thereof causes the lock mechanism to move to the retracted position, the lock cylinders each including a first keyhole. A tamper resistant member is moveable between a protected position in which the keyhole of the second cylinder is inaccessible and an unprotected position in which the keyhole of the second cylinder is accessible, such that a tool is required in order to move the tamper resistant member from the protected position to the unprotected position, the tool adapted to be stored separately from the door.

Abstract: A sliding door locking system includes a sliding door having an inner surface that slides over a doorway opening when the door is slidably mounted above the doorway opening, and an outer surface. A lock housing is mounted in the sliding door, the housing having an aperture extending through the inner surface of the sliding door. A latch is hingedly mounted in the aperture such that the latch is moveable from a retracted position, in which the door is slidable along the door opening, and an extended position, in which the latch engages a catch opposite the inner surface of the door and adjacent the doorway opening. At least one of the inner and outer surfaces of the sliding door includes an actuator that, when moved from a first position to a second position, moves the latch from the retracted position to the extended position.

Abstract: A sliding door system with a door includes a horizontally elongated member having a mounting portion with which it is mounted to a support structure, and a horizontally elongated track extending downwardly therefrom. The horizontally elongated track includes a horizontally elongated upper portion having a width, and a horizontally elongated protuberance below the upper portion having a width greater than the width of the upper portion. At least one sliding element is mounted to the top of the door and has a channel corresponding to the protuberance, and in which part of the elongated protuberance is disposed such that the sliding element is retained by and slidable on the protuberance. In some embodiments, a vertically extending rod is concealed between the front and back walls of the door and can be moved vertically in and out of an aperture in the protuberance to lock and unlock the door.

Abstract: A delayed return mechanism, such as for a door latch, including a housing having a hole with an axis, a cavity in the housing at least partially filled with a fluid media, a hub disposed in the cavity including a spindle hole coaxial with the hole in the housing including teeth within the spindle hole to engage a spindle, the hub being rotatable about the axis and having a fin extending radially outward in the cavity, and a channel through which the fluid media passes during rotation of the hub to control flow of the fluid media about the cavity.

Abstract: A bolt assembly usable in a mortise lock. The assembly includes a bolt and tailpiece that are pivotable relative to one another. In one embodiment, the bolt and tailpiece are joined by a pin that permits the components to pivot relative to one another.

Abstract: A motorized deadbolt cylinder assembly includes a housing having a generally cylindrical side wall, a generally planar outer end wall disposed at a first end of the side wall and a generally planar inner end wall disposed at a second end of the side wall opposite to the first end. The assembly also includes a motor disposed within the housing, the motor having a drive shaft, and a cam arranged on the inner end wall and arranged such that at least a portion thereof is disposed outside of the housing. A gear train is operably connected between the drive shaft of the motor and the cam such that rotation of the drive shaft of the motor causes rotation of the cam, such that the cam rotates with an increase in mechanical advantage as compared to rotation of the drive shaft of the motor.

Abstract: A door latch mechanism including a latch housing, a bolt having a proximal end with a head and a distal end having a latch, a hub including a central bore for receiving a spindle, a lever actuated by rotation of the hub, the lever including a slot in a top portion of the lever receiving the head of the bolt such that the lever and the bolt move together in both rearward and forward directions.

Abstract: A door handle has an elongated member pivotally connected with a plate member. The elongated member has a toe portion which interacts with the plate member. In this way, the elongated member is at least partially retained by the plate member at each end. The door handle provides an anti-ligature design that thwarts suicide attempts by persons attempting to affix or hang ligatures on the door handle. The door handle is also easily operable by those with disabilities.
