A latch assembly that is adjustable between first and second backset settings. A cam is rotatable about a cam axis, and facilitates linear displacement of a latch link in a first direction. A multiplier link is rotatable about a multiplier link axis that is offset from the cam axis can be rotated in the first rotational direction by engagement with the latch link. A latch bar is coupled to the multiplier link and is linearly displaced in a second direction by rotation of the multiplier link in the first direction. The latch apparatus also includes a latch bolt that is coupled to the latch bar, the latch bolt being displaced toward a retracted position by the displacement of the latch bar in the second direction. The latch assembly can also include a dead latch link can block retraction of at least the latch bolt.

An exemplary pushbutton mechanism is configured for use with a lockset including a spindle and a plunger extending into the spindle, and generally includes a first component, a second component, and a cam interface. The first component is configured for rotational coupling with the plunger and for axial coupling with the spindle, and is rotatable between a locking orientation and an unlocking orientation. The second component is configured for rotational coupling with the spindle and for axial movement relative to the first component and the spindle, and is axially movable between a depressed position and a projected position. The cam interface is configured to correlate rotation of the first component with axial displacement of the second component.

Pushbutton mechanisms for locksets

A hoop lock including a shackle and a crossbar, with the shackle having a pair of legs extending from a body portion, and each of the legs having a foot including a tip with a non-circular cross-section. The cross-bar includes a housing having a pair of foot-receiving openings and a pair of tip-receiving openings substantially aligned with foot-receiving openings. The tip-receiving openings are configured to matingly engage the tips such that the tips are rotationally coupled to the housing.

Hoop lock with anti-rotation features

A hoop lock assembly including a shackle and a crossbar. The shackle includes a straight foot and an angled foot. The crossbar is operable to receive the straight foot and the angled foot, and includes a primary locking mechanism and a secondary locking mechanism. The primary locking mechanism is operable to selectively prevent removal of the straight foot from the crossbar. The secondary locking mechanism is operable to selectively prevent removal of the angled foot from the crossbar.
