Abstract:
A control assembly for holding a pivoted door in an open position and releasable to enable the door to swing on a pivot axis to a closed position, comprising,a rotor, means connecting said rotor to the door in a manner such that when the door is swung to the open position the rotor is rotated in one direction to a locking position and when the door is swung to the closed position the rotor is rotated from said locking position in a direction opposite said one direction, a locking detent having a part engagable with a complementary part on said rotor when the rotor is rotated in said one direction to said locking position to prevent the rotor from rotating in said opposite direction and thereby to hold the door in the open position thereof, means for retracting the detent away from the rotor to disengage said parts when the rotor is rotated in said one direction past said locking position to a release position, and means for holding said detent retracted until the rotor is rotated in the opposite direction from the release position past the locking position to permit the door to swing to the closed position thereof.
