Abstract
Abstract A solar energy system for selectively absorbing or reflecting radiant energy entering through a window of a structure, the system comprising a window drape having a decorative side and a back side, and a removable liner adjacent the backside of the window drape. At least one side of the liner or window drape backside is a radiant energy reflecting surface and another of said sides is a radiant energy absorbing surface. Thus, depending upon the season of the year, the system may be arranged to selectively provide the appropriate surface to optimize or minimize the radiant energy maintained within the structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A solar energy absorption control system comprising: pliant window drapes having a decorative side and a back side; a pliant drape liner having first and second sides; fastening means releasably attaching the drape liner to the backside of the window drapes; the backside of the drapes and the first and second sides of the liner comprising at least one radiant energy reflecting surface and at least one radiant energy absorbing surface; whereby the decorative side of the drapes may be positioned adjacent a window facing into the interior of the structure and, depending upon the season, the radiant energy reflecting surface positioned to reflect radiant energy back through the window or, alternatively, the radiant energy absorbing surface positioned to absorb the radiant energy and provide heat energy to the interior of the structure.
Claim 2
Dependent Claim
133 words
A solar energy absorption control system comprising: pliant window drapes having a decorative side and a back side; a pliant drape liner having first and second sides; fastening means releasably attaching the drape liner to the backside of the window drapes; the backside of the drapes and the first and second sides of the liner comprising at least one radiant energy reflecting surface and at least one radiant energy absorbing surface; whereby the decorative side of the drapes may be positioned adjacent a window facing into the interior of the structure and, depending upon the season, the radiant energy reflecting surface positioned to reflect radiant energy back through the window or, alternatively, the radiant energy absorbing surface positioned to absorb the radiant energy and provide heat energy to the interior of the structure.
Claim 3
Dependent Claim
63 words
A solar energy system as set forth in claim 1 in which the backside of the drape is the radiant energy reflecting surface and the first side of the drape liner is the radiant energy absorbing surface; whereby the drape liner may be removed in warm weather to reflect the energy and the drape liner positioned to absorb the energy in cooler weather.
Claim 4
Dependent Claim
63 words
A solar energy system as set forth in claim 1 in which the backside of the drapes is the radiant energy absorbing surface and the first side of the drape liner is the radiant energy reflective surface; whereby the drape liner may be removed in cold weather to absorb the energy and the drape liner positioned to reflect the energy in warmer weather.
Claim 5
Dependent Claim
96 words
A solar energy system as set forth in claim 1 in which the first side of the drape liner is the radiant energy reflective surface and the second side of the liner is the radiant energy absorbing surface whereby the first side of the liner may be positioned facing away from the backside of the drapes when it is desired to minimize the radiant energy absorbed and the second surface is positioned facing away from the backside of the drapes when desired to maximize the radiant energy absorbed and maintained within the interior of a structure.
Claim 6
Dependent Claim
26 words
A solar energy system as set forth in claim 1 in which the fastening means comprise drape hangers adjacent an upper edge of the drape hanger.
Claim 7
Dependent Claim
30 words
A solar energy system as set forth in claim 1 in which the fastening means comprise complementary snaps on the backside of the window drapes and on the drape liner.
Claim 8
Dependent Claim
18 words
A solar energy system as set forth in claim 1 in which the fastening means are Velcro fasteners.
Claim 9
Dependent Claim
20 words
A solar energy system as set forth in claim 1 in which the radiant energy absorbing surface is substantially black.
Claim 10
Dependent Claim
20 words
A solar energy system as set forth in claim 1 in which the radiant energy reflecting surface is substantially white.
