Patent number: 6183023Abstract: A door with an integrated exit device has an operational bar which at least partially extends across the door. The operational bar is located within a recess in the face of the door. The operational bar has at least one arm that extends into a channel, which is formed in cooperation with the recess. The door has a locking channel which extends along the vertical edge of the door. The locking channel is coupled to a vertical stile that is fixedly located on the vertical edge of the door. The locking channel and the vertical stile are pivotally coupled by a clip. A blocking member is located within the vertical stile. The operational bar has an actuator arm located within the door and within the vertical stile. As the operational bar is pushed inward, actuator arm pushes blocking member to an open position which also allows locking channel to pivot to an open position.Type: GrantFiled: November 20, 1998Date of Patent: February 6, 2001Inventor: Leon Yulkowski

Patent number: 6049287Abstract: A door has a first outer face having an opening therein and a second outer face spaced a predetermined distance apart from the first outer face. A hold open device is located substantially between the first and second outer faces. The hold open device holds the door in an open position. A smoke detector is also located substantially between the first and second outer faces adjacent to the opening. The smoke detector is electrically coupled to the magnetic hold open so that upon detection of smoke, the smoke detector causes the hold open to release the door from an open position to a closed position.Type: GrantFiled: March 2, 1998Date of Patent: April 11, 2000Inventor: Leon Yulkowski
