Door and window construction and mounting assembly for improved security, ventilation and aesthetics

A new and improved door construction and mounting assembly for improved security, ventilation and aesthetics comprising, in combination:

• a steel frame in a rectangular configuration having short horizontal parallel upper and lower extents and long vertical parallel interior and exterior side extents with at least one central opening extending therethrough, the interior extent having hinges for the pivotal securement to a casement and the exterior extent having a handle assembly for locking and unlocking the door;
• a panel positioned within the central opening, the panel having a gridwork of horizontally disposed steel members and vertically disposed steel members in a gridlock configuration to form rectangular apertures extending therethrough, the vertical steel members having axially aligned bores therethrough, with the spacing between the apertures sized such as to preclude the passage of a person therethrough, the panel having a plurality of inserts located within the apertures with vertical disposed hinges coupling the inserts and the vertical steel members for allowing the selective covering and uncovering of the apertures;
• and
• adjustment mechanisms for moving the inserts between closed positions and open positions, the adjustment mechanisms including a horizontally disposed rotary drive rod with exterior threads on the surface thereof located through the aligned bores, cylindrical collars with interior threads located at spaced points along the length of the drive rod at locations adjacent to the inserts, coupling links pivotally secured between the cylindrical collars and the ends of the inserts remote from the hinges and a worm gear coupled to the drive rod with a handle located on the inside of the door whereby rotation of the handle and the worm gear will rotate the drive rod to move the cylindrical collars in unison to pivot the inserts between open positions and closed positions at the discretion of an operator.
