Abstract: An improved door access bar for installation onto a door through which access is controlled by an electrically operated door access system is disclosed in which the door access bar has an electromechanically operable door locking mechanism which is used to selectively lock and unlock the door to thereby control access or egress through the door. The door access locking bar of the present invention incorporates an interlock mechanism to prevent the bolt from being forced into a retracted position by jimmying the locking mechanism to unlock the door. The locking mechanism of the present invention prevents the door from being opened until the electromechanical locking mechanism is operated to do so. The door access locking bar of the present invention operates in a fail-safe manner so that in the event of a power failure it will automatically be in an unlocked position.

Abstract: An improved pressure-actuated door access bar is disclosed which may be located on a door to control access or egress through the door, whereby the door access bar is used to trigger unlocking or opening, or both unlocking and opening, of the door following pressure being exerted on the door access bar by an individual desiring access or egress through the door. Two electromechanical force transducer assemblies having no moving parts are mounted within a rigid base member which may in turn be mounted on a door or in another desired location, and a cover member mounted over the base member exerts pressure on the electromechanical force transducer assemblies when pressure is placed on it. When a given amount of pressure is detected by either or both of the electromechanical force transducer assemblies, the door will be unlocked or opened, or both unlocked and opened.
