Patent ID: 8215049

Claim:
A telescoping tube apparatus, for attachment to a plurality of opposing vehicle vertical roll bar members of an all terrain vehicle, supporting a firearm and creating a longitudinal sight plane comprising: a. a first tubular member of predetermined size having an exterior end and an interior end; b. a second tubular member of predetermined size having an exterior end and an interior end; said second tubular member interior end being telescopically received by said first tubular member; c. an annular O-ring, seated upon the interior end of the second tubular member; d. a horizontal axial hinge compression bracket coupling comprising a horizontally mounted female, open end, hinge bracket clamp for securing to the exterior end of said telescoping tubes in a fixed horizontal position to produce a horizontal frame assembly wherein said horizontal axial hinge compression bracket coupling being attached to a telescoping tube end by means of compression; e. a horizontal axial hinge compression bracket coupling for securing the exterior ends of said telescoping tubes in fixed positions to produce a horizontal frame assembly wherein said horizontal axial hinge compression bracket coupling is attached to a vehicle vertical member by means of compression; f. an elongated bolt channel passage opening at opposing ends in first tubular member's top and bottom exterior end and an elongated bolt channel passage opening at opposing ends in the second tubular member's top and bottom exterior end creating an elongated bolt channel passage for a tightening device consisting of a bolt, and nut; g. a mounting means for the exterior end of said first tubular member and mounting means for the exterior end of said second tubular member for mounting said first and second tubular member to a horizontal axial hinge compression bracket coupling; h. a mounting means for the exterior end of said first tubular member's horizontal axial hinge compression bracket coupling and mounting means for the exterior end of said second tubular member's horizontal axial hinge compression bracket coupling for mounting said first and second tubular member horizontal axial hinge compression bracket coupling onto a vehicle's vertical member.
