Claim:
A door strike mechanism to be mounted in a door frame to cooperate with a door latch on a door, said mechanism comprising: a support; a catch moveably mounted on the support in position to engage the door latch to hold the door closed; a biasing element urging the catch into position to hold the door closed; a pin having a locking position in which it prevents the catch from moving out of the door closed position; a pressure responsive sensor initiating action to move the pin into an unlocked position permitting the catch to move when a sudden change in air pressure on one side of the door occurs, thus allowing the door to open; a first roller mounted on said catch to engage one side of the pin when an opening force is applied to the door; and a second roller rotatably mounted on said support and engaging an opposite side of the pin to receive a load applied to the catch, said first and second rollers being mounted to be in rolling engagement with said pin to aid in movement of said pin when it is being moved to the unlocked position.
