Abstract
Abstract A solar heated portable structure comprising a flexible bottom panel, a flexible side assembly and a flexible transmitting panel, all coupled together and supported to form an enclosed chamber. The transmitting panel is capable of transmitting a majority of the radiant energy from the solar radiation spectrum to heat the enclosed chamber like a sauna and has an area at least 0.7 the area of the bottom panel to maximize heating while minimizing material costs. The transmitting panel can be transparent to ultraviolet radiation to allow persons inside the chamber to be tanned.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
161 words
A solar heated collapsible and portable structure comprising: a flexible bottom panel that is dark in color to absorb radiant energy; a flexible side assembly coupled to said bottom panel; a flexible transmitting panel coupled to said bottom panel and side assembly; a support frame coupled to said transmitting panel to support said transmitting panel above and over said bottom panel, said bottom panel, side assembly and transmitting panel forming an enclosed chamber so that wind cannot easily penetrate the interior defined thereby, said transmitting panel being capable of transmitting a majority of the radiant energy from the solar radiation spectrum to heat said enclosed chamber and act like a sauna, the area of said transmitting panel being at least 0.7 the area of said bottom panel; and means for selectively venting said enclosed chamber to the atmosphere and for providing ingress and egress to said enclosed chamber, whereby persons in said enclosed chamber can enjoy the heated space defined thereby.
Claim 2
Dependent Claim
161 words
A solar heated collapsible and portable structure comprising: a flexible bottom panel that is dark in color to absorb radiant energy; a flexible side assembly coupled to said bottom panel; a flexible transmitting panel coupled to said bottom panel and side assembly; a support frame coupled to said transmitting panel to support said transmitting panel above and over said bottom panel, said bottom panel, side assembly and transmitting panel forming an enclosed chamber so that wind cannot easily penetrate the interior defined thereby, said transmitting panel being capable of transmitting a majority of the radiant energy from the solar radiation spectrum to heat said enclosed chamber and act like a sauna, the area of said transmitting panel being at least 0.7 the area of said bottom panel; and means for selectively venting said enclosed chamber to the atmosphere and for providing ingress and egress to said enclosed chamber, whereby persons in said enclosed chamber can enjoy the heated space defined thereby.
Claim 3
Dependent Claim
36 words
A structure according to claim 1, wherein said transmitting panel is formed of material that transmits a majority of the radiant energy in the visible part of the solar radiation spectrum and is therefore visibly transparent.
Claim 4
Dependent Claim
37 words
A structure according to claim 1, wherein said transmitting panel is formed of material that transmits only a part of the radiant energy in the visible part of the solar radiation spectrum and is therefore visibly translucent.
Claim 5
Dependent Claim
37 words
A structure according to claim 1, wherein said transmitting panel is formed of material that transmits radiant energy in the ultraviolet part of the solar radiation spectrum, thereby allowing persons in said enclosed chamber to be tanned.
Claim 6
Dependent Claim
23 words
A structure according to claim 1, wherein said side assembly has a reflective surface on the inside thereof to reflect the radiant energy.
Claim 7
Dependent Claim
37 words
A structure according to claim 1, wherein said side assembly is formed of a material that transmits a majority of the radiant energy in the visible part of the solar radiation spectrum and is therefore visibly transparent.
Claim 8
Dependent Claim
27 words
A structure according to claim 1, wherein said side assembly is formed of material that transmits radiant energy in the ultraviolet part of the solar radiation spectrum.
Claim 9
Dependent Claim
26 words
A structure according to claim 1, wherein said bottom panel is substantially U-shaped in plan view, and said transmitting panel is substantially U-shaped in plan view.
Claim 10
Dependent Claim
34 words
A structure according to claim 8, wherein said support frame comprises a substantially U-shaped first support member coupled to said bottom panel, and a substantially U-shaped second support member coupled to said transmitting panel.
Claim 11
Dependent Claim
21 words
A structure according to claim 9, wherein said support frame further comprises means for interconnecting said first and second support members.
Claim 12
Dependent Claim
56 words
A structure according to claim 1, wherein said bottom panel is substantially in the form of a hexagon, said transmitting panel comprises at least two faces extending from at least two of the sides of said hexagonal bottom panel, and said side assembly comprises the remaining faces extending from the sides of said hexagonal bottom panel.
Claim 13
Dependent Claim
56 words
A structure according to claim 1, wherein said bottom panel is substantially in the form of a rectangle, said transmitting panel comprises a semi-cylindrical face extending from two of the sides of said rectangular bottom panel, and said side assembly comprises two substantially semi-circular faces extending from the remaining two sides of said rectangular bottom panel.
Claim 14
Dependent Claim
38 words
A structure according to claim 1, wherein said bottom panel is substantially in the form of a rectangle, said transmitting panel is substantially in the form of a rectangle, and said side assembly comprises two substantially triangular faces.
Claim 15
Dependent Claim
45 words
A structure according to claim 1, wherein said bottom panel is substantially in the form of a rectangle, said transmitting panel and said side assembly are in the form of a pyramid, said transmitting panel comprising at least two of the faces of such pyramid.
Claim 16
Dependent Claim
171 words
A solar heated collapsible and portable structure comprising: a flexible, generally planar bottom panel that is dark in color to absorb radiant energy; a flexible side assembly coupled to said bottom panel; a flexible, generally planar transmitting panel coupled to said bottom panel and side assembly; a support frame coupled to said transmitting panel to support said transmitting panel above and over and at an acute angle to said bottom panel, said bottom panel, side assembly and transmitting panel forming an enclosed chamber so that wind cannot easily penetrate the interior defined thereby, said transmitting panel being capable of transmitting a majority of the radiant energy from the solar radiation spectrum to heat said enclosed chamber and act like a sauna, the area of said transmitting panel being at least 0.7 the area of said bottom panel; and means for selectively venting said enclosed chamber to the atmosphere and for providing ingress and egress to said enclosed chamber, whereby persons in said enclosed chamber can enjoy the heated space defined thereby.
