CA 2236383

An electronically operated lock has a latch mechanism which is operable by a rotatable spindle. The spindle can be rotated manually either by an inside turn lever or a key operated outside plug or rotated electronically. A pinion is secured to the spindle and a slider supported for vertical dis:placement has a vertical rack which cooperates with the pinion. The slider has vertically separated upper and lower control surfaces and a rotatable wheel gear has an eccentric axially extending finger located intermediate the upper and lower control surfaces. The wheel gear is driven by a single direction motor through gearing. The upper and lower control surfaces are selectively located so that when the finger is rotated in one direction from a 3:00 position to a 9:00 position, the displacement of the slider will displace the bolt to the retracted position and so that when the finger is rotated in that direction from the 9:00 position to the 3:00 position, the displacement of the slider will displace the bolt to the advanced position.
