Abstract
A storm window type closure which is adapted to be installed adjacent the interior side of an existing primary window unit. The present invention incorporates a main frame and associated runner assembly of such a low profile that the designed movement of the primary window unit may be accomplished without undue obstruction thereby allowing convenient access to the same. Additionally the present invention provides a substantial dead air space between the primary window and the storm window thereby increasing both the acoustic and thermal insulation qualities of the same. The present invention relates to windows and more particularly to storm windows which are adapted to be installed adjacent a preexisting primary window unit.
Claims8
An improved storm window for use in conjunction with a primary window disposed within a window opening of a building, comprising:
- a main frame disposed interiorly of and generally about an area adjacent the primary window to be insulated, said main frame including an inside terminal edge that terminates interiorly of the primary window and which abuts to the inside periphery thereof;
- said main frame further including an elongated member that extends inwardly from said inside terminal edge along and adjacent said primary window opening and includes a tongue type coupling extension that extends from the end opposite said terminal edge and which is spaced inwardly from the primary window opening;
- a runner extrusion assembly adapted to be detachably mounted to the tongue type coupling extension of said elongated member of said main frame, said runner extrusion assembly including a tongue receiving opening for receiving said tongue type coupling extension of said elongated member of said main frame and wherein said tongue receiving opening is formed by first and second extensions that form a part of said runner extrusion assembly, said first extension extending between said primary window opening and said elongated member of said main frame and said second extension extending adjacent the inside of said elongated member of said main frame on the side opposite said first extension;
- said runner extrusion assembly further including at least two runner extrusions extending inwardly from said second extension to form a groove interiorly of said primary window;
- means for detachably securing said runner extrusion assembly to said elongated member of said main frame;
- and sash means secured within said runner extrusions in spaced apart relationship with respect to said primary window to form a storm window interiorly of said primary window.
