Abstract:
A clutch mechanism for a door having a lockset with a lockable latch and an actuator for operating said latch, said clutch mechanism comprising:first coupling means comprising a rotatable assembly for selectively translating rotatable motion applied at one side of said door;second coupling means comprising a rotatable assembly for selectively translating rotational motion applied at one side of said door; andclutch means for selectively engaging said first and second coupling means, said clutch means comprising:pin means carried by said first coupling means in rotatable relationship with said door for forcing said pin means into engagement with said second coupling means;injector means comprising a movable wall with a concave arcuate surface engageable against said pin means, said pin means slidably engageable along the concave arcuate surface of said wall; anddrive means for driving said injector means between first and second positions to selectively engage said first coupling means in fixed rotational relationship with said second coupling means which permits operation of said latch from said one side, said drive means comprising a motor and a drive link comprising a spring shaft drivable by said motor for axially displacing said injector means.
