Abstract
An improved lock strike plate and security chain means are rotatably coupled within a recess within the strike plate means as well as within a recess of the door frame to which the strike plate is mounted. Means are provided within the security chain latching means to inhibit the decoupling of a security chain latched thereto when the door is placed ajar. Further means are provided for exterior key actuation of the chain latch to permit decoupling of the latch from a security chain by a person outside the secured area in an emergency situation. Orthogonal coupling means matingly engaged within the interior of the door frame itself strengthen the strike plate/chain latch assembly, reinforcing the door frame and making that frame a more integral part of the door locking assembly than has been heretofore achieved in the prior art.
