Adjustable mirror mount

Claim 2

An adjustable light reflective surface for an image projection system having an optical center line comprising: a member having a light reflective surface; a pivot point adjacent said light reflective surface and substantially in line with said optical center line of said projector system; means to resiliently bias said member against said pivot point; first means for adjustably rotating said member about a first axis passing through said pivot point; second means for adjustably rotating said member about a second axis substantially perpendicular to said first axis and also passing through said pivot point.

Claim 3

An adjustable light reflective surface for an image projection system having an optical center line comprising: a member having a light reflective surface; a pivot point adjacent said light reflective surface and substantially in line with said optical center line of said projector system; means to resiliently bias said member against said pivot point; first means for adjustably rotating said member about a first axis passing through said pivot point; second means for adjustably rotating said member about a second axis substantially perpendicular to said first axis and also passing through said pivot point.

Claim 4

An adjustable light reflective surface for an image projection system having an optical center line comprising: a member having a light reflective surface; a pivot point adjacent said light reflective surface and substantially in line with said optical center line of said projector system; means to resiliently bias said member against said pivot point; first means for adjustably rotating said member about a first axis passing through said pivot point; second means for adjustably rotating said member about a second axis substantially perpendicular to said first axis and also passing through said pivot point.

Claim 5

The apparatus according to claim 1 wherein: said light reflective surface includes a mirror.

Claim 6

The apparatus according to claim 1 wherein: said first adjusting means and said pivot establish said second axis; and said second ajusting means and said pivot establish said first axis.

Claim 7

The apparatus according to claim 1 wherein: said biasing means is located on a line extension that lies between said first and second axis at a location remote from said adjusting means and the intersection of said first and second axis.

Claim 8

An adjustable light reflective surface for an image projection system having an optical center line comprising: a base; a member having a light reflective surface on at least one side thereof; a pivot extending from said base and in contact with the other side of said member at a point substantially in line with said optical center line; a first rotational axis and a second rotational axis perpendicular to said first axis; the intersection of said first axis with said second axis being adjacent said reflective surface and corresponding to said point of contact of said pivot with said other side of said member; first adjusting means coupled between said member and said base and located in line with said first axis a distance from the intersection of said first and second axis; second adjusting means coupled between said member and said base and located in line with said second axis a distance from the intersection of said first and second axis; biasing means coupled to said base and said member and located on a line extension that substantially bisects the angle between said first and second axis; said biasing means being located along said bisecting line remote from the intersection of said first and second axis and said first and second adjusting means.

Claim 9

An adjustable light reflective surface for an image projection system having an optical center line comprising: a base; a member having a light reflective surface on at least one side thereof; a pivot extending from said base and in contact with the other side of said member at a point substantially in line with said optical center line; a first rotational axis and a second rotational axis perpendicular to said first axis; the intersection of said first axis with said second axis being adjacent said reflective surface and corresponding to said point of contact of said pivot with said other side of said member; first adjusting means coupled between said member and said base and located in line with said first axis a distance from the intersection of said first and second axis; second adjusting means coupled between said member and said base and located in line with said second axis a distance from the intersection of said first and second axis; biasing means coupled to said base and said member and located on a line extension that substantially bisects the angle between said first and second axis; said biasing means being located along said bisecting line remote from the intersection of said first and second axis and said first and second adjusting means.

Claim 10

The apparatus according to claim 5 further including: an opening in said member; said biasing means including a post secured to said base and extending through said opening; said post having a flanged portion at the end thereof remote from said base; spring means interposed between said flanged portion and said member for urging said member against said pivot.

Claim 11

The apparatus according to claim 5 further including: first and second openings in said member; said first and second adjusting means including an adjustable screw extending through each said opening and in threaded engagement with said base.
