Abstract:
A latch assembly includes a chassis, a latch bolt moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, a pawl having an engaged position at which the pawl is engaged with the latch bolt to hold the latch bolt in the closed position and a disengaged position at which the pawl is disengaged from the latch bolt, thereby allowing the latch bolt to move to the open position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis. The eccentric arrangement is rotatable about the eccentric axis, and the pawl is rotatable about the pawl axis. When the pawl moves from the engaged position to the disengaged position, the eccentric arrangement rotates in one of a clockwise and a counter-clockwise direction about the eccentric axis. With the pawl in the engaged position, a force applied to the pawl by the latch bolt creates a turning moment on the eccentric arrangement in the one of the clockwise and counter-clockwise direction, and the eccentric arrangement is prevented from rotating in said one of the clockwise and counter-clockwise direction by a moveable abutment.
