Patent ID: 7707798

Claim:
A screening device comprising: a) at least two panels, each having a pair of parallel opposite edges; b) a panel assembly that holds said panels at a predetermined location; c) said panel assembly comprising a framework including: 1) an upper rigid elongate substantially channel shaped top panel retaining member held in an upper lengthwise horizontal position with at least two, spaced-apart upper channels facing substantially downward; 2) a lower rigid elongate substantially channel shaped bottom panel retaining member held in a lower lengthwise horizontal position with at least two, spaced-apart lower channels being parallel to, and facing substantially upward toward said top panel retaining member; 3) said upper channels spaced apart sufficiently from each other and said lower channels spaced apart sufficiently from each other to allow for unobstructed passage of said panels with respect to each other on lateral movement of said panels in said spaced-apart upper and lower channels; and 4) end caps positioned over the ends of at least one of 1) said spaced-apart upper channels and 2) said spaced-apart lower channels to prevent said panels from being removed from said upper channels and said lower channels by lateral movement of said panels in said upper and lower channels; d) a corner supporting structure with said corner supporting structure further comprising: 1) a vertical corner member; 2) two lower horizontal members, each with first and second ends, with said horizontal members attached at right angles to each other at their first end portions to a lower portion of said vertical corner member; 3) two vertical angular support members, each with first and second ends, with said vertical angular support members attached at their lower first end portions to said second end portions of said horizontal members and at their upper end portions to an upper portion of said vertical corner member; and 4) a horizontal corner member attached at its end portions to said second end portions of said two horizontal members; and e) a panel rolling member assembly allowing said panels to roll in said upper channels of said top panel retaining member or in said lower channels of said lower panel retaining member.
