Abstract
Abstract A portable mirror for use in hunting includes a tripod base having individually adjustable legs for adapting to various terrain configurations. A central vertical post is mounted on the tripod and supports a pair of articulating mirrors. The mirrors are individually rotatably adjustable about their own longitudinal axes as well as pivotally adjustable about the longitudinal axis of the post. The mirrors are vertically slidable along the post relative to the ground.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
262 words
Apparatus comprising: a support rod; bracket means slidably mounted on said support rod; at least two mirrors articulatingly supported in said bracket means and pivotally movable about an axis parallel to said support rod; means comprising a plurality of legs for supporting said apparatus, said legs being coupled to said support rod and being individually adjustable to permit said support rod to remain relatively vertical on uneven terrain; said bracket means including at least one pair of opposed spherical chambers, each chamber having an elongated slot formed therein; said mirrors each having a generally spherical protruberance received by one of said chambers for being articulatingly supported in said bracket means; said bracket means having a generally vertical aperture for receiving said support rod; means for deforming said bracket aperture to increase the friction between said aperture and said support rod; said means for supporting said apparatus comprising block means having a plurality of apertures and a generally tubular leg slidably received in each aperture, each leg frictionally contacting said aperture; said block means having a central aperture for receiving said support rod; and each of said plurality of apertures extending at an acute angle relative to a horizontal plane and having a generally circular opening on one side of said block tapering to a generally elliptical opening on the opposite side of said block, said legs being pivotable within said aperture between a first position and a second position, said legs being freely slidable relative to said block in said first position, and frictionally fixed in said block in said second position.
Claim 2
Dependent Claim
262 words
Apparatus comprising: a support rod; bracket means slidably mounted on said support rod; at least two mirrors articulatingly supported in said bracket means and pivotally movable about an axis parallel to said support rod; means comprising a plurality of legs for supporting said apparatus, said legs being coupled to said support rod and being individually adjustable to permit said support rod to remain relatively vertical on uneven terrain; said bracket means including at least one pair of opposed spherical chambers, each chamber having an elongated slot formed therein; said mirrors each having a generally spherical protruberance received by one of said chambers for being articulatingly supported in said bracket means; said bracket means having a generally vertical aperture for receiving said support rod; means for deforming said bracket aperture to increase the friction between said aperture and said support rod; said means for supporting said apparatus comprising block means having a plurality of apertures and a generally tubular leg slidably received in each aperture, each leg frictionally contacting said aperture; said block means having a central aperture for receiving said support rod; and each of said plurality of apertures extending at an acute angle relative to a horizontal plane and having a generally circular opening on one side of said block tapering to a generally elliptical opening on the opposite side of said block, said legs being pivotable within said aperture between a first position and a second position, said legs being freely slidable relative to said block in said first position, and frictionally fixed in said block in said second position.
Claim 3
Dependent Claim
155 words
Apparatus comprising: a support rod; bracket means slidably mounted on said support rod; at least two mirrors articulatingly supported in said bracket means and pivotally movable about an axis parallel to said support rod; means for supporting said apparatus comprising block means having a plurality of apertures and a generally tubular leg slidably received in each aperture, each leg frictionally contacting each aperture; said block means having a central aperture for receiving said support rod; and each of said plurality of apertures extending at an acute angle relative to a horizontal plane and having a generally circular opening on one side of said block tapering to a generally elliptical opening on the opposite side of said block, said legs being pivotable within said aperture between a first position and a second position, said legs being freely slidable relative to said block in said first position, and frictionally fixed in said block in said second position.
Claim 4
Dependent Claim
155 words
Apparatus comprising: a support rod; bracket means slidably mounted on said support rod; at least two mirrors articulatingly supported in said bracket means and pivotally movable about an axis parallel to said support rod; means for supporting said apparatus comprising block means having a plurality of apertures and a generally tubular leg slidably received in each aperture, each leg frictionally contacting each aperture; said block means having a central aperture for receiving said support rod; and each of said plurality of apertures extending at an acute angle relative to a horizontal plane and having a generally circular opening on one side of said block tapering to a generally elliptical opening on the opposite side of said block, said legs being pivotable within said aperture between a first position and a second position, said legs being freely slidable relative to said block in said first position, and frictionally fixed in said block in said second position.
Claim 5
Dependent Claim
51 words
Apparatus as set forth in claim 2, wherein: said bracket means includes at least one pair of opposed spherical chambers, each chamber having an elongated slot formed therein; and said mirrors each having a generally spherical protruberance received by one of said chambers for being articulatingly supported in said bracket means.
Claim 6
Dependent Claim
25 words
Apparatus as defined in claim 3, including: means for deforming said bracket central aperture to increase the friction between said aperture and said support rod.
