Frameless supplemental window for fenestration
First Claim
1. A supplemental window apparatus comprising:
- a constraint configured to be coupled to a window pane of an existing window and to provide a slot between the constraint and the window pane;
a foot configured to be at least partially inserted into the slot to detachably couple the foot to the window pane such that the foot extends substantially parallel to the window pane when at least partially inserted into the slot, wherein the foot is separately detachable from the window pane without detaching at least a portion of the constraint from the window pane;
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; and
a substantially non porous sheet coupled to the spacer and having a sheet area substantially similar to a window pane area defined by interior surfaces of a first window element holding the window pane, wherein the spacer and the foot substantially define 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 first window element.

Abstract
A novel and useful frameless supplemental window for fenestration incorporating infiltration blockers suitable for use with existing windows. The supplemental window, in one embodiment, comprises plastic sheet material with bullnose edging around it. Corner braces add rigidity and strength to corners in several embodiments. An attachment mechanism secured either to the sheet material or the bullnose edge functions to fasten and/or seal the supplemental window to an existing window. Infiltration blockers fastened to the sheet or bullnose prevent or minimize air leakage around various window elements. The bullnose edging and infiltration blockers function to substantially enclose (i.e. trap) a volume of air between the window pane and the plastic sheet material. The supplemental window is configured such that the layer of air enclosed is of an optimum thickness within a preferred range of 0.15 to 0.75 inches to maximize thermal insulation properties of the supplemental window.

15. A supplemental window apparatus comprising:
-
a constraint configured to be coupled to a window pane of an existing window, wherein the constraint comprises an adhesive along edges of the constraint configured to be located at a corner area of the window pane to form a slot between the constraint and the window pane, wherein the slot is defined by a volume between the constraint and the window pane where the adhesive is not present when the constraint is installed; a foot configured to be at least partially inserted into the slot to detachably couple the foot to the window pane such that the foot extends substantially parallel to the window pane when at least partially inserted into the slot, wherein the foot is separately detachable from the window pane without detaching at least a portion of the constraint from the window pane; 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; and a substantially non porous sheet coupled to the spacer and having a sheet area substantially similar to a window pane area defined by interior surfaces of a first window element holding the window pane, wherein the spacer and the foot substantially define 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 first window element.
