Abstract:
A releasable locking assembly for selectively locking and unlocking a door control cylinder, having a spring biased rod member extending from an end thereof, the assembly comprising:(a) a movable locking member encircling the cylinder rod member and retained within a first confining member secured to an end of the control cylinder with the rod member extending through the first confining member, the movable locking member biased against an interior end of the first confining member opposite the control cylinder; (b) a biased, linear actuating member paralleling the rod member and traversing the first confining member end opposite the cylinder, the actuating member movable to cant the locking member upon the rod member to secure the rod member in an extended condition; and (c) a second confining member moveably secured to said first confining member and operatively connected to said biased, linear actuation member, whereby moving the second confining member toward the first confining member causes the biased actuation member to cant the locking member on the rod member to lock the rod member in an extended condition from the control cylinder, the locking member releasing the rod member upon further extending the rod member from the control cylinder.
