Abstract A mirror mounting is described in which a plane rectangular reflecting strip is deformed along the two longer edges thereof so that it is approximately tangent to the ideal mirror while the strip remains substantially flat in the direction of its shorter edges. In the preferred embodiment of the invention, a plurality of such reflecting strips are so formed by attachment to a supporting frame using a pair of elastomeric cushion frames to embrace the longer sides of each strip while leaving the shorter sides free. Advantageously, each reflecting strip on the frame is bent in a continuous manner the full distance of its longer side. The frame is preferably a rigid array of parallel channel members each of which is adapted to receive a curved T-section angle bar having the desired curvature of the reflecting strip. The angle bars are deformed into this curvature in a separate operation while they are being attached to the channel members. Specific apparatus for deforming the reflecting strips into conformity with the curved angle bars and for attaching the strips to the cushion frames is also described.
A mirror comprising a plurality of reflecting components mounted on a frame said frame comprising an array of spaced-apart substantially parallel support members, said members being curved to conform generally to the contour of a continuously curved mirror, said reflecting components comprising plane rectangular reflecting strips, the longer sides of said reflecting strips being attached between pairs of the support members and being deformed by attachment means to conform in the direction of their longer dimension to the curvature of the support members, and the shorter sides of said reflecting strips being substantially flat.

A mirror comprising a plurality of reflecting components mounted on a frame said frame comprising an array of spaced-apart substantially parallel support members, said members being curved to conform generally to the contour of a continuously curved mirror, said reflecting components comprising plane rectangular reflecting strips, the longer sides of said reflecting strips being attached between pairs of the support members and being deformed by attachment means to conform in the direction of their longer dimension to the curvature of the support members, and the shorter sides of said reflecting strips being substantially flat.
Claim 3
Dependent Claim
63 words
The mirror of claim 1 in which the length of the rectangular reflecting strip in one direction is approximately equal to the spacing between adjacent support members and the edges of the reflecting strip in the other direction are fastened to the support members by a means which deforms the edges of the reflecting strip into approximately the curvature of the support members.
Claim 4
Dependent Claim
50 words
The mirror of claim 2 wherein there are at least three support members in said array and at least one reflecting strip is attached between each pair of adjacent support members and each reflecting strip is substantially flat along the direction that is the shortest distance between adjacent support members.
Claim 5
Dependent Claim
