1. A method to provide in a wall of a building structure a low-profile secure canine access, the wall including an exterior side including a vertically oriented exterior face and an interior side including a vertically oriented interior face, the method comprising the steps of
(a) forming an access opening through the wall, said opening extending from said exterior face through the wall to said interior face and having a first peripheral edge, a top, a bottom, and sides extending between said top and said bottom; (b) providing a door structure mountable in said opening in the wall, said door structure including
(i) at least one side sized to extend at least partially through said opening from said exterior face to said interior face, and(ii) a flange (61) connected to said at least one side and shaped and dimensioned to extend substantially around said top, bottom and sides of said opening and laterally away from the opening over and contacting and parallel to a portion of said exterior face of the wall adjacent the opening, said flange having a second peripheral edge spaced away from said opening and a selected thickness such that
said flange projects a selected distance outwardly from said exterior face of the wall, andsaid flange is not inset in said wall; (c) providing a first security member (11) separate from said door structure and shaped and dimensioned to be mounted on and overlie and enclose said flange and including
(i) a generally orthogonal substantially flat frame panel (20) having a third peripheral edge and an outwardly facing first exterior surface,(ii) a generally orthogonal door opening formed through said frame panel, said opening including a top, a bottom, a first side, and a second side, said door opening, frame panel, exterior surface, and third peripheral edge generally lying in a common plane,(iii) at least a pair of spaced apart security hinges each including
a base fixedly secured to said frame panel at said first side of said opening, anda hinge joint attached to and outwardly projecting from said base and spaced apart from said frame panel,(iv) a first portion of a manually operable locking latch mechanism on said frame panel at said second side of said opening,(v) an outwardly extending secondary edge (20A, 20B, 20C, 20D) extending substantially the entire distance around, substantially enclosing, connected to and perpendicular to said third peripheral edge of said frame panel, said secondary edge having a width generally equivalent to said thickness of said flange and having a distal lip (70) spaced apart from said frame panel such that
said distal lip (70) is not inset in said wall, and,said secondary edge (20A, 20B, 20C, 20D) and frame panel (20) substantially obscure from view said flange and said second peripheral edge from view,(vi) said common plane, said frame panel, said door opening, and said third peripheral edge each being located on said exterior side of said wall and spaced outwardly apart from said exterior face of said wall,(vii) said common plane generally being parallel to and spaced apart from said exterior face,(vii) said secondary edge extending outwardly from said exterior face of said wall; (d) providing a second security member (12) comprising
(i) a generally orthogonal door panel having top, a second exterior surface, bottom and side edges, and at least two operative positions,
a first operative closed position, anda second operative open position,said door panel shaped and dimensioned to fit in, substantially fill, conform to, and be flush with said door opening in said first operative position such that
said top edge is adjacent said top of said door opening,said first exterior surface is flush with said second exterior surface and lies in said common plane,said bottom edge is adjacent said bottom of said door opening, and each of said side edges is adjacent a different one of said first and second sides of said door opening,(ii) at least a pair of spaced apart hollow security hinge members each
operatively associated with a different one of said security hinges,fixedly secured to said door panel,shaped and dimensioned to be removably mounted on a different one of said hinge joints by sliding rotatably downwardly over said different one of said hinge joints and substantially completely cover and enclose said different one of said hinge joints,(iii) a second portion of said manually operable locking latch mechanism, said locking latch mechanism having a first operative open locked configuration in which said second portion engages said first portion and said door panel is locked in a closed position and a second operative unlocked configuration in which said door panel can freely pivot on said hinge joints to an open position,said door panel, when mounted flush with said frame panel (20), being on said exterior side of said wall and spaced outwardly apart from said exterior face of said wall,said flange, first security member, and second security member each not being inset in said wall and being positioned on said exterior side of said wall; (e) mounting said door structure in said opening with said flange adjacent and contacting the exterior face of the wall; (f) mounting said first security member on the exterior face of the wall with
(i) said frame panel extending over and adjacent said flange,(ii) said lip circumscribing, enclosing, and adjacent said second peripheral edge of said flange and adjacent and contacting the exterior face of the wall,(iii) said door opening generally in registration with said first peripheral edge of said access opening, and,(iv) said door opening, frame panel, and common plane on said exterior side of said wall and spaced outwardly apart from said exterior face; (g) mounting said second security member on said first security member by sliding said security hinge members over said hinge joints; and, (h) closing said door panel by pivoting said door panel on said hinge joints to move said door panel into registration and flush with said door opening; (i) manually operating said latch mechanism into said second locked configuration. |
