Abstract
Abstract In a preferred embodiment of the invention, a mirror antiscratch protector case mountable on a dental mirror, having a spaced-away recess portion of an interior concave wall surface with spaced-apart points on the interior concave wall surface on each of opposite sides of the recess portion supportable of mirror bezel structure of mirror mounting structure, and having a biasing spring positioned to press a mounted dental mirror's mirror bezel structure against the spaced-apart points, and having a barrier structure pressing against a leading edge of the mirror bezel structure when the mirror is mounted within the protector case such that the reflective surface of the mounted mirror is retained opposite the recess portion, with opposite edges of the protector case in alignment with the spaced-apart points converging from a wide to narrow width of the protector case such that varying sizes of dental mirrors are received and such that narrower portions of the concave wall surface serve as the barrier structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A mirror protector case comprising in combination: a mirror cover means for protecting a mirror reflective surface against contact with exterior objects and against contact with an interior surface of the mirror cover means, said mirror cover means including a cover structure having an interior-space surface of concave shape formed as a centrally positioned recess positioned between spaced-apart mirror-contact surfaces, and said mirror cover means further including spring structure mounted on said cover structure and positioned to exert biasing pressure against a rearward wall of a mirror such that mirror bezel structure on each of opposite sides of and adjacent to reflective mirror structure, is pressed against said spaced-apart mirror-contact surfaces, said recess being sufficiently concave that exposed mirror reflective surface is devoid of contact with and is spaced from said interior surface when mirror bezel structure is pressed against the spaced-apart mirror-contact surfaces.
Claim 2
Dependent Claim
144 words
A mirror protector case comprising in combination: a mirror cover means for protecting a mirror reflective surface against contact with exterior objects and against contact with an interior surface of the mirror cover means, said mirror cover means including a cover structure having an interior-space surface of concave shape formed as a centrally positioned recess positioned between spaced-apart mirror-contact surfaces, and said mirror cover means further including spring structure mounted on said cover structure and positioned to exert biasing pressure against a rearward wall of a mirror such that mirror bezel structure on each of opposite sides of and adjacent to reflective mirror structure, is pressed against said spaced-apart mirror-contact surfaces, said recess being sufficiently concave that exposed mirror reflective surface is devoid of contact with and is spaced from said interior surface when mirror bezel structure is pressed against the spaced-apart mirror-contact surfaces.
Claim 3
Dependent Claim
48 words
A mirror protector case of claim 1, in which said mirror cover means includes barrier structure positioned such that when a mirror is mounted between said spring structure and said spaced-apart mirror-contact surfaces, said barrier structure presses against mirror bezel structure preventing further lateral movement of the mirror.
Claim 4
Dependent Claim
24 words
A mirror protector case of claim 2, in which said cover structure is substantially semicircular along an axis extending between said spaced-apart mirror-contact surfaces.
Claim 5
Dependent Claim
26 words
A mirror protector case of claim 3, in which said spring structure includes an arcuate flange extending from at least one edge of said cover structure.
Claim 6
Dependent Claim
22 words
A mirror protector case of claim 4, in which said spring structure is an extension of and continuation of said barrier structure.
Claim 7
Dependent Claim
26 words
A mirror protector case of claim 2, in which said spring structure includes an arcuate flange extending from at least one edge of said cover structure.
Claim 8
Dependent Claim
40 words
A mirror protector case of claim 6, in which said spring structure includes one of said arcuate flanges at each of opposite spaced-apart edges of said cover structure substantially in alignment with an axis extending between said spaced-apart mirror-contact surfaces.
Claim 9
Dependent Claim
126 words
A mirror protector case of claim 7, in which relative to a first axis extending between said spaced-apart mirror-contact surfaces, the cover structure extends along a second axis that is substantially perpendicular to said first axis and width of the cover structure as it extends along said second axis is wider at a first end of said second axis and narrowing to a narrower width at a second opposite end of said second axis, said narrower width being of a predetermined dimension of lesser width than a mirror to be mounted within said mirror cover means such that the cover structure at said narrower width functions as barrier structure that presses against a mirror bezel structure when a mirror is mounted within the mirror cover means.
Claim 10
Dependent Claim
126 words
A mirror protector case of claim 1, in which relative to a first axis extending between said spaced-apart mirror-contact surfaces, the cover structure extends along a second axis that is substantially perpendicular to said first axis and width of the cover structure as it extends along said second axis is wider at a first end of said second axis and narrowing to a narrower width at a second opposite end of said second axis, said narrower width being of a predetermined dimension of lesser width than a mirror to be mounted within said mirror cover means such that the cover structure at said narrower width functions as barrier structure that presses against a mirror bezel structure when a mirror is mounted within the mirror cover means.
Claim 11
Dependent Claim
19 words
A mirror protector case of claim 9, in which said cover structure is substantially semicircular along said first axis.
Claim 12
Dependent Claim
26 words
A mirror protector case of claim 10, in which said spring structure includes an arcuate flange extending from at least one edge of said cover structure.
Claim 13
Dependent Claim
35 words
A mirror protector case of claim 11, in which said spring structure includes one of said arcuate flanges at each of opposite spaced-apart edges of said cover structure substantially in alignment with said first axis.
