Replacement window unit

Abstract

Abstract THIS IS A REPLACEMENT WINDOW UNIT PRIMARILY DESIGNED FOR REHABILITATION OF OLDER DWELLING HOUSES. THE INVENTION IS PRIMARILY RELATED TO EFFECTUATING A FIVE TRACK UNIT WHEREIN TWO STORM PANELS, A SCREEN PANEL AND TWO REGULAR GLASS PANELS ARE ALL EMBODIED IN ONE UNIT TRAVELING ON PARALLEL TRACKS EACH PANEL BEING INDEPENDENTLY ADJUSTABLE AND HAVING A LATCH MECHANISM OPERABLE ONLY FROM THE INSIDE SO THAT THE WINDOW MAY NOT BE OPERATED BY BURGLARS SUBSTANTIALLY FROM THE OUTSIDE. BEING OF COMPACT THICKNESS WITH ADJACENT PANELS SUBSTANTIALLY TOUCHING OR EFFECTIVELY TOUCHING, EACH PANEL IS EASILY AND SIMPLY REMOVABLE FROM THE FRAME. THE FRAME IS ADJUSTABLE TO FIT THE WINDOW OPENING PROVIDED, AND THE WINDOWS ARE IN A TIGHT, RATTLE-FREE RELATIONSHIP TO THE FRAME. FIVE TRACK WINDOWS HAVE NOT BEEN PRODUCED IN THE PRIOR ART BECAUSE IN ACCORDANCE WITH THE USUAL DESIGN PRINCIPLES, SUCH A WINDOW WOULD BE QUITE IMPRACTICAL. FOR EXAMPLE, EITHER THE WINDOW WOULD HAVE TO BE VERY THICK WITH THE TRACKS WIDELY SPACED APART OR ELSE IT WOULD BE IMPOSSIBLE TO ADJUST THE OUTSIDE PANEL AS FOR EXAMPLE MOVING IT OUT OF THE TOP POSITION WITHOUT REMOVING ALL OF THE OTHER PANELS IN FRONT OF IT OR ELSE BY PROVIDING OPERABLE CATCHES OR RELEASES ON THE OUTSIDE OF THE WINDOW MAKING IT READILY AVAILABLE TO BE OPENED BY A BURGULAR. A FEATURE HELPING TO SOLVE THIS PROBLEM IS A SYSTEM OF STEPPED DOWNWARDLY SLOPING TOWARD THE OUTSIDE TOP AND BOTTOM INTERIOR FRAME SURFACES. THUS WHEN THE OUTSIDE LOWER PANEL IS IN THE RAISED POSITION, THE LOWER PORTION THEREOF HAVING THE CATCH LEVER MECHANISM THEREON IS EXPOSED BELOW THE BOTTOM OF THE UPPER SECTION. LIKEWISE THE SIDES ARE STEPPED INWARDLY TOWARD THE OUTSIDE OF THE BUILDING. THE MANY FEATURES OF THE INVENTION WHICH PROVIDE AN OPERABLE UNIT OF THIS TYPE WILL BE EXPLAINED IN THE DETAILED DESCRIPTION.
