Patent ID: 7428792

Claim:
A hand held display device comprising a floating cowling comprising a tubular housing having a longitudinal slit; a first spool rod retained within the tubular housing, the first spool rod having a distal end and a proximal end; a distal aligning yoke coupled to the distal end of the first spool rod; a proximal aligning yoke coupled to the proximal end of the first spool rod, the distal aligning yoke and the proximal aligning yoke configured to rotationally support and axially align the tubular housing around the first spool rod to allow free rotation of the tubular housing about the first spool rod; a flexible material having a fixed end and a free end, the fixed end coupled to the first spool rod; a pull tab coupled to the free end of the flexible material, the pull tab configured to prevent the free end of the flexible material from passing through the longitudinal slit into the tubular housing; whereby the flexible material is movable through the longitudinal slit between a retracted position having the flexible material wrapped around the first spool rod inside the tubular housing and an extended position having a majority of the flexible material outside the tubular housing; wherein the distal aligning yoke has a distal raised annular ridge along an outer circumference of the distal aligning yoke; and wherein the proximal aligning yoke has a proximal raised annular ridge along the outer circumference of the proximal aligning yoke, the distal and proximal raised annular ridges configured to rotationally support and axially align the tubular housing around the first spool rod.
