Abstract
Abstract An improved mirror including a cushion intermediate the mirror's reflecting surface and the mirror's support surface which cushion absorbs any surface irregularity in the support surface and causes the support surface to present a substantially flat support surface to the reflecting surface whereby any distorting effect of the surface irregularity on images produced by the mirror's reflecting surface is substantially eliminated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
Apparatus providing a mirror, comprising: support means having a support surface for supporting mirror means, said support surface having surface irregularity; mirror means including a layer of predetermined plastic film having a metallized surface on one side providing a reflecting surface that produces images by reflection and having a backing surface on the opposite side opposed to said support surface; and cushion means intermediate said support surface and said mirror means, said cushion means for substantially absorbing said surface irregularity thereby causing said support surface to present a substantially flat support surface to said mirror means whereby the distorting effect of said surface irregularity on the images produced by said reflecting surface is substantially eliminated.
Claim 2
Dependent Claim
115 words
Apparatus providing a mirror, comprising: support means having a support surface for supporting mirror means, said support surface having surface irregularity; mirror means including a layer of predetermined plastic film having a metallized surface on one side providing a reflecting surface that produces images by reflection and having a backing surface on the opposite side opposed to said support surface; and cushion means intermediate said support surface and said mirror means, said cushion means for substantially absorbing said surface irregularity thereby causing said support surface to present a substantially flat support surface to said mirror means whereby the distorting effect of said surface irregularity on the images produced by said reflecting surface is substantially eliminated.
Claim 3
Dependent Claim
35 words
Apparatus according to claim 1 wherein said predetermined plastic film comprises polyester film substantially 0.003-0.007 inch thick and wherein said metallized surface is a layer of metallized aluminum substantially 3 ohms per square area thick.
Claim 4
Dependent Claim
21 words
Apparatus according to claims 1 or 2 wherein said cushioning means is a layer of polyether foam substantially 0.025 inch thick.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 3 further including adhesive means for securing said cushion means to said supporting surface and to said mirror means.
Claim 6
Dependent Claim
82 words
Apparatus for providing a mirror, comprising: a rigid mirror support surface having surface irregularity; a non-rigid mirror having a reflecting surface that produces images by reflection; and a layer of conformable material conforming to said surface irregularity and for causing said support surface to present a flat support surface to said non-rigid mirror whereby the distorting effect of said surface irregularity on images produced by said mirror is substantially eliminated, said conformable material secured to said support surface and to said mirror.
Claim 7
Dependent Claim
82 words
Apparatus for providing a mirror, comprising: a rigid mirror support surface having surface irregularity; a non-rigid mirror having a reflecting surface that produces images by reflection; and a layer of conformable material conforming to said surface irregularity and for causing said support surface to present a flat support surface to said non-rigid mirror whereby the distorting effect of said surface irregularity on images produced by said mirror is substantially eliminated, said conformable material secured to said support surface and to said mirror.
Claim 8
Dependent Claim
19 words
Apparatus according to claim 5 wherein said layer of conformable matter is a layer of closed cell polyether foam.
Claim 9
Dependent Claim
107 words
Apparatus for providing a mirror, providing: a rigid mirror support surface having surface irregularity; a flexible mirror having a backing surface and a reflecting surface that produces images by reflection; and a layer of closed cell polyether foam intermediate said support surface and said flexible mirror, said foam conforming to said surface irregularity of said mirror of said rigid mirror support surface and providing a flat surface for engaging and supporting said flexible mirror whereby the distorting effect of said surface irregularity on the images produced by said reflecting surface is substantially eliminated, said layer of foam secured to said support surface and to said flexible mirror.
Claim 10
Dependent Claim
107 words
Apparatus for providing a mirror, providing: a rigid mirror support surface having surface irregularity; a flexible mirror having a backing surface and a reflecting surface that produces images by reflection; and a layer of closed cell polyether foam intermediate said support surface and said flexible mirror, said foam conforming to said surface irregularity of said mirror of said rigid mirror support surface and providing a flat surface for engaging and supporting said flexible mirror whereby the distorting effect of said surface irregularity on the images produced by said reflecting surface is substantially eliminated, said layer of foam secured to said support surface and to said flexible mirror.
