The solar mirror apparatus has an elongate support frame on which resiliently flexible sheet metal mirrors (15) are secured in a parabolically curved arrangement, with an elongate solar radiation receiver (28) being mounted at the focal line of the sheet metal mirrors (15). The support frame is swivellable about an axis which extends parallel to the focal line of the parabola. The carrying frame has two spaced apart clamping section supports (11) disposed opposite and parallel to one another. The mirror plates are carried by parabolic webs (13) with the mirror plates being fitted shapewise on the parabolic edges (17) of the parabolic webs (12). The ends of the parabolic webs (12) which extend between the clamping section supports (11) are swivellably supported at the confronting sides of the clamping section supports (11) about swivel axes (14) which extend parallel to the longitudinal axes (13) of the clamping section supports (11). The clamping section supports (11) have an elongate abutment (16) which extends parallel to the swivel axis ( 14) at the side of the swivel axis facing the parabolic edges (17). The end edges of the mirror plates (15) contacting the abutment (16), whereby the mirror plates (15) are held in compression and their shape is determined by the parabolic webs (13).

A solar mirror apparatus, comprising: an elongate carrying frame, having a longitudinal axis, adapted to be rotated about said longitudinal axis; first and second clamping section supports, spaced apart and disposed parallel to said longitudinal axis, each said support including an elongate abutment, parallel to and facing said longitudinal axis, adapted to exert a compressive force, and further including an elongate slot, parallel to said longitudinal axis; means for adjustably connecting said supports to said frame such that each said support can swivel about a support swivel axis parallel to said longitudinal axis; a parabolic web including first and second parallel sides, each said side including a swivel pin defining a web swivel axis parallel to said longitudinal axis; first and second pivotal connecting means for pivotally connecting said web to said supports, each said pivotal connecting means adapted to slidadably attach to a said support and rotably engage a said swivel pin, thereby pivotally connecting said web to said supports; an elastically flexible sheet metal mirror having first and second parallel sides, adapted to be releasably held against and conformed to the shape of said parabolic web, said mirror sides contacting said abutments and being forced by the compressive force exerted by said abutments to conform to the parabolic shape of said web, an upper surface of said mirror defining a parabolic mirror having a focal line parallel to said longitudinal axis when so shaped; and an elongate radiation receiver, held by said frame and disposed at said focal line, for receiving solar radiation reflected by said mirror; said means for adjustably connecting allowing the supports to be swiveled to a release position permitting said mirror to be placed on or removed from said web, whereupon said means for adjustably connecting is tightened placing said supports in a mirror retaining position, said pivotal connecting means controlling the contact between said mirror sides and said abutments, and controlling thereby the compressive force exerted by said abutments to force said mirror to assume the parabolic shape of said web; said frame being rotated to cause said mirror to face the sun.
