Claims21
A solar collector assembly comprising
- (a) a planar base,
- (b) a frame around the periphery of said base,
- (c) flexible glazing spanning said frame and covering said base,
- (d) said frame including at least one pivotable elongated member having an edge portion movable away from an opposite portion of the frame,
- (e) adjustable securing means connecting the pivotable frame member with respect to the base, and
- (f) said glazing being secured along one edge to the movable edge portion of the pivotable frame member and also secured to said opposite portion of the frame,
- (g) whereby said pivotable frame member is pivoted by said securing means so that its edge portion moves away from the opposite portion of the frame to tension the glazing.

A solar collector assembly comprising
- (a) a rectangular planar base,
- (b) a frame around the periphery of said base,
- (c) a flexible glazing film spanning said frame and covering said base,
- (d) 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,
- (e) adjustable securing means connecting the pivotable frame members to the base, and
- (f) said glazing film being secured along opposite edges to the movable edge portions of the pivotable frame members,

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.
