Abstract: An exemplary door closer has an adjustable size and includes a rotatable member operable to adjust the size and an indicator mechanism configured to indicate the current size. The indicator mechanism includes a cover mounted to a housing of the door closer and a dial rotatably mounted to the cover. The dial is engaged with the rotatable member such that the dial rotates in response to rotation of the rotatable member. The cover includes an indicating region, and the dial includes a display surface including indicia relating to the sizes of the door closer. The display surface is non-perpendicular to the rotational axis of the rotatable member. When the door closer has been adjusted to a particular size, indicia relating to the particular size are indicated by the indicating region.

Abstract: 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.

Abstract: An exemplary noise-reducing mechanism for door hardware includes a housing, a damper, and a stop. The door hardware includes a first component and a second component, and an operational movement of the door hardware causes relative movement of the first and second components. The housing is mounted to the first component, and the damper is mounted to the housing. The stop is mounted to the second component such that the stop engages the damper during the operational movement. The damper is configured to slow the operational movement, thereby reducing noise generated by operation of the door hardware.

Abstract: A lock device that prevents operation of at least one chassis spindle from retracting a latch bolt, and which may provide auto-unlock features. Locking of the lock device can effectuate linear displacement of a slider body from an unlocked position to a locked position. Linear displacement of the slider body is translated into rotational displacement of a cam body that includes, or is coupled to, a locking shaft having a cam protrusion, thereby rotating the cam protrusion. As the cam protrusion rotates, the cam protrusion lifts a locking lug to a locked position wherein the locking lug prevents rotational displacement of a first chassis spindle. When in the locked position, a slider arm of the slider body can be positioned in a retention slot. Subsequent rotable displacement of a second chassis spindle can effectuate displacement of the slider arm from the retention slot and facilitate unlocking of the lock device.

Abstract: An exemplary shackle is configured for use with a crossbar having a pair of openings and a locking mechanism including a pair of deadbolts. The shackle includes a substantially flat plate portion having a length in a longitudinal direction, a width in a transverse direction, and a thickness along a lateral axis defining a proximal direction and a distal direction. The length is greater than the width, which is greater than the thickness. The shackle further includes a pair of longitudinally-offset legs extending distally from the plate portion. Each leg has a diameter, and includes a bumper and a notch positioned distally of the bumper. An offset distance is defined between the distal surface of the plate portion and the distal faces of the bumpers. The width of the plate portion is greater than each of the diameter and the offset distance.

Abstract: An electronic reader may operate in a normal mode. The reader may evaluate criteria to determine whether to continue operating in the normal mode or operate in a secure mode. The secure mode may include deactivating functionality in the reader. Deactivating functionality may include at least one of disabling a credential reading functionality, disabling a credential processing functionality, and disabling a credential communicating functionality.

Abstract: A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.

The electronic lock device is configured to transition between a locked state and an unlocked state in response to receiving the lock/unlock command and without requiring rotation of the mechanical key.
