ABSTRACT:
A novel rack-pinion forms an outside operator of either a single latchbolt or a double latchbolt with the pinion rotating a latch operator of at least a single latchbolt to move the bolt between extended and retracted positions. The rack is shiftable between pinion engaging and nonengaging positions as determined by an inside operator control button, this being the sole means of shifting in the simplist, single latchbolt form. When it is a single latchbolt form, a lock may be added to the outside operator for also shifting the rack-pinion construction. In more complex, double latchbolt form, the second bolt, preferably a deadbolt, may have an outside operator formed by a lock or an inside operator formed by a turnpiece of both. With the outside lock of the second bolt construction, a yoke may connect that to the rack-pinion construction of the first latchbolt for shifting the rack by the second latchbolt outside lock. Also, a panic assembly may be connected between the inside operator of the first latch bolt and the latch operator of the second latchbolt with either the second latchbolt outside lock or inside turnpiece or both for simultaneous operation of the second latchbolt upon operation of the first latchbolt by the inside operator.
