Patent ID: 7000362

Claim:
A screening apparatus comprising: a) at least two panels, each having a pair of parallel opposite edges; and b) means for holding said panels at a predetermined location; c) said holding means 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 top panel retaining member and said bottom panel retaining member being spaced from each other so as to prevent removal of said panels by moving said panels upward in said upper channels and swinging a lower edge of said panels away from said lower channels; 4) 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 slidable lateral movement of said panels in said spaced-apart upper and lower channels; and 5) 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; and 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 ends 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 ends to said second ends of said horizontal members and at their upper ends to an upper portion of said vertical corner member; and 4) a horizontal corner member attached at its ends to said second ends of said horizontal members.
