Frameless supplemental window for fenestration
First Claim
1. A supplemental window apparatus comprising:
- a foot and a first constraint element attached to the foot, wherein the foot and the first constraint element are configured to be detachably coupled to a window pane of an existing window through a mating constraint element attached at a perimeter location of the window pane defined by interior surfaces of a window element holding the window pane when installed, such that the foot extends substantially parallel to the window pane when installed on the existing window;
a spacer coupled to the foot and configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window, wherein at least one surface of the spacer is configured to be located closer to the window pane than the first constraint element when the first constraint element is coupled to the mating constraint element; and
a substantially non porous sheet coupled to the spacer and having a sheet area substantially similar to a window pane area defined by the interior surfaces of the first window element holding the window pane, wherein the spacer substantially defines a gap between the sheet and the window pane when installed on the existing window, and wherein the foot extends outward from the spacer toward the interior surfaces of the window element.

Abstract
A supplemental window apparatus includes a foot and a first constraint element attached to the foot. The foot and the first constraint element are configured to be detachably coupled to a window pane of an existing window through a mating constraint element. A spacer is coupled to the foot and is configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window. A substantially non porous sheet is coupled to the spacer and has a sheet area substantially similar to a window pane area defined by the interior surfaces of the first window element holding the window pane. The spacer substantially defines a gap between the sheet and the window pane when installed on the existing window. The foot extends outward from the spacer toward the interior surfaces of the first window element.

7. A supplemental window apparatus, a portion of which is configured to be detachably coupled to a window pane of an existing window, the supplemental window apparatus comprising:
-
a spacer coupled to a foot having a first constraint element located thereon, a substantially non porous sheet coupled to the spacer, and a seal attached along each edge of the substantially non porous sheet, wherein the seal contacts the spacer when the seal is compressed against the window pane when the supplemental window apparatus is mounted on the window pane; a mating fastener element located on the window pane inward in a direction toward a center of the window pane from at least one feature of the existing window when the supplemental window apparatus is mounted, the mating fastener element is attached to a perimeter area of the window pane, wherein the mating fastener element comprises an interlocking feature configured to engage in an interpenetrating engagement with the first constraint element of the foot. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A supplemental window apparatus, a portion of which is configured to be detachably coupled to a window pane of an existing window, comprising:
-
a spacer, a substantially non porous sheet coupled to the spacer, and an edge seal coupled to the substantially non porous sheet; a constraint located on the window pane inward in a direction toward a center of the window pane from at least one feature of the existing window when the supplemental window apparatus is mounted, the constraint attached to a perimeter area of the window pane, wherein the constraint comprises a magnet, and a flap attached to the non porous sheet has a magnet for coupling to the constraint magnet.
