Abstract
Abstract A connector for door frames and the like defined by perpendicular stiles and rails and disposed at corners between them. A central portion of the connector flush with the exterior of the adjacent stiles and rails. Connector extensions are disposed interiorly of the stiles and rails and frictionally connect the stiles and rails to each other to form a rigid door frame. Connecting members are also disclosed which can be placed between aligned sections of a stile or a rail for mounting handles, door locks and the like to the frame.

355 words
An assembly for a screen door and the like comprising an outer frame defined by perpendicular tubular stiles and tubular rails, the stiles and rails having a lesser overall length than the overall dimensions of the door, and a connector between each set of adjacent stiles and rails, each connector having a portion disposed between and in abutment with ends of an adjacent stile and rail, the portion having an exterior configuration substantially identical to the exterior configuration of the adjacent stile and rail to form a continuous outer door frame defined by the stiles, the rails and the connectors, each connector including reduced cross section extensions depending from the portion and dimensioned to snugly, frictionally engage an interior of the contiguous stile and rail to thereby secure and position the stile, the rail and the connector to each other, each extension including a free end having at least two sets of opposing tapered sides terminating in an extension end which has a redUced cross section as compared to a remainder of the extensions to facilitate the insertion of the remainders into the adjoining stile and rail, the portion of at least two aligned connectors only including a cutout, the cutouts being aligned, each such cutout being further spaced from the adjoining stile and rail so as to not interrupt the continuity of the stiles and the rails, a roller assembly, means mounting the roller assembly to the connector and positioning the assembly in an interior space defined by the connector only and being spaced from the adjoining stile and rail, means biasing at least part of the roller through the cutout to the exterior of the connector for guiding the frame during movements along a track, the stiles, the rails and the connectors further defining a smooth, continuous, generally U-shaped open channel running along an inner edge of the frame, flexible screen means disposed over an area included by the frame, and means securing edges of the screen means into the continuous channel to thereby mount the screen means and mechanically lock the screen means to the stiles, the rails, and the corner fasteners.
