Redundant electrically controlled locking apparatus |
摘要 |
An apparatus for releasing a locking arrangement in response to an electrical control signal to unlock a closure member, employs a pair of first and second piston cylinder assemblies that are facing one another and disposed in alignment with one another within a housing for actuating alternatingly in response to the control signal. The assemblies have reciprocatively mounted plungers for moving extensively toward and away from one another along a rectilinear path of travel. A shuttle is slideably mounted within the housing and connected on opposite sides to the distal ends of the plungers to move toward an actuated one of the cylinder assemblies. A locking cam disposed on the shuttle receives and locks a roller to position the roller partially outwardly of the housing within a side opening in the housing, and a pair of first and second unlocking cams enable the roller to move inwardly of the housing when either one of the cylinder assemblies is activated. The locking arrangement includes a locking mechanism with a slide member that is adapted to be moved manually for releasing the closure member, and the slide member has an opening for receiving the roller to lock the closure member.
