摘要： A flush mounted latch for a door that includes a housing, a bolt, first apparatus, and second apparatus. The first apparatus includes a pinion gear that is operatively connected to the bolt, a pivot arm that is pivotally mounted at one end to, but off center of, the pinion gear and pivotally mounted at another end to the bolt which allows the bolt to retract when the pinion gear is rotated, a first rack that is operatively connected to the second apparatus and gearingly engages an edge of the pinon gear, and when caused to move inwardly by the second apparatus, rotates the pinion gear and retracts the bolt, a second rack that is operatively connected to the second apparatus and gearingly engages an opposite edge of the pinon gear, and when caused to move inwardly by the second apparatus, rotates the pinion gear and retracts the bolt. The second apparatus includes a first plunger plate connected to the first rack for movement therewith, and when pushed, the first plunger plate causes the first rack to move inwardly and rotate the pinion gear and retract the bolt and a second plunger plate connected to the second rack for movement therewith, and when pushed, the second plunger plate causes the second rack to move inwardly and rotate the pinion gear and retract the bolt.
