Abstract:
An electrically operated lock comprising:a latch mechanism with a dead bolt that is movable in a lateral direction between a retracted and an advanced position; a spindle defining an axial direction that is transverse to said lateral direction, coacting with said latch mechanism, and turnable to displace said dead bolt between said retracted and advanced positions; and an actuating unit including: a swing member coacting with said spindle and swingable along with rotation of the spindle, a slider coacting with said swing member and movable in a direction substantially parallel to said lateral direction between a first and a second position, a first cam mechanism having a first cam member that is provided on said slider, and a first cam follower that is provided on said swing member and cooperates with said first cam member for moving said slider between said first and second positions, a wheel member selectively coacting with said slider, a second cam mechanism having: a second cam member that is provided on said slider, and a second cam follower that is provided on said wheel member and cooperates with said second cam member for moving said slider between said first and second positions; a motor coacting with said wheel member for turning said wheel member; said slider is disposed between said swing member and said wheel member; said first cam member is defined by a camming face formed on the slider; said second cam member is defined by two opposing curved ribs projecting in a direction substantially parallel to said axial direction of said spindle toward said wheel member, said two curved ribs confining a cam moving space therebetween, said camming face being disposed at a center position between said curved ribs; and said first cam follower projecting in a direction substantially parallel to said axial direction of said spindle to engage said camming face, said second cam follower projecting in a direction substantially parallel to said axial direction into said cam moving space to engage one of said curved ribs.
