Claim 12

A solar collector assembly according to claim 9 wherein cord means are hemmed along said edge portions of the glazing film, and longitudinally slotted groove means are provided on the movable edge portion of the pivotable frame member into which the cord means is threaded and held with the glazing film extending therefrom.

Claim 13

A solar collector assembly according to claim 9 wherein the base includes a rigid backing and an insulated base sheet disposed over the backing.

Claim 14

A solar collector assembly according to claim 9 wherein multi-tube strips of extruded rubber are disposed on the base with the tubes thereof interconnected for circulation of a heat exchange liquid.

Claim 15

A solar collector assembly according to claim 9 wherein the securing means are spring-biased screws.

Claim 16

A solar collector assembly according to claim 9 wherein sequential flexure means are provided to maintain substantially constant tension on the film.

Claim 17

A solar collector assembly according to claim 9 wherein the sequential flexure means are spring means associated with the securing means and a bendable neck portion on each pivotable elongated member.

Claim 18

A solar collector assembly according to claim 9 wherein acoustical absorbing material is disposed within a slot in the base under the glazing film.

Claim 19

A solar collector assembly comprising (a) a rectangular planar base including: (i) a plywood backing, and (ii) an insulated base sheet disposed over said backing; (b) a frame around the periphery of said base; (c) a flexible translucent glazing film spanning said frame and covering said base; (d) multi-tube strips of extruded rubber disposed lengthwise on said base sheet with the tubes thereof interconnected for circulation of a heat exchange liquid; (e) said frame including two pivotable elongated members along opposed longer sides of the rectangular base and having opposed upper edge portions movable away from one another; (f) cord means hemmed within opposed longitudinal edge portions of said glazing film; (g) adjustable spring-biased securing screws connecting the pivotable frame members to the base; and (h) longitudinally slotted groove means in the upper edge portion of the pivotable frame members into which the cord means is threaded and held with the glazing film extending therefrom; (i) whereby said pivotable frame members are pivoted by securing screws so that their edge portions move apart to tension the glazing.

Claim 20

A solar collector assembly comprising (a) a rectangular planar base including: (i) a plywood backing, and (ii) an insulated base sheet disposed over said backing; (b) a frame around the periphery of said base; (c) a flexible translucent glazing film spanning said frame and covering said base; (d) multi-tube strips of extruded rubber disposed lengthwise on said base sheet with the tubes thereof interconnected for circulation of a heat exchange liquid; (e) said frame including two pivotable elongated members along opposed longer sides of the rectangular base and having opposed upper edge portions movable away from one another; (f) cord means hemmed within opposed longitudinal edge portions of said glazing film; (g) adjustable spring-biased securing screws connecting the pivotable frame members to the base; and (h) longitudinally slotted groove means in the upper edge portion of the pivotable frame members into which the cord means is threaded and held with the glazing film extending therefrom; (i) whereby said pivotable frame members are pivoted by securing screws so that their edge portions move apart to tension the glazing.
