Claim:
A closure assembly to be installed in an opening for a building, said closure assembly comprising a frame for supporting a moveable closure member therewithin, said frame including top, bottom and side members, at least two opposing of said members including a hollow pocket within the interior of said member having interior surfaces having a first shape and adapted for matingly receiving a spring biased roller assembly and integral mounting brackets, upon which a flexible material is accumulated, said flexible material being engaged with a draw bar at the free end thereof, and engaged with a spring biased roller at the other end, said spring biased roller being engaged with said integral mounting brackets permitting slidable installation and removal of the spring biased roller assembly and said integral mounting brackets in mating engagement within the hollow pocket, each of said integral mounting brackets having a leading edge matingly compatible in shape with said interior surfaces of said hollow pocket and thereby prevented from movement as said integral mounting brackets matingly engage with the interior surfaces of the hollow pocket and another of the top, bottom and side members, absent any further fastener, permitting slidable removal and replacement of said roller assembly and said integral mounting brackets; said flexible material being selected from a blind, a bug screen, and a solar screen, the flexible material being movable between a fully retracted first position whereat the material is contained within the pocket of said member to a fully extended second position whereat the material covers some or all of the opening of the building; said integral mounting brackets remaining unfastened with respect to said frame, permitting slidable removal and replacement of said roller assembly integral with said mounting brackets from/to said hollow pocket, wherein the draw bar is connected to the free end of said flexible material, and said draw bar includes guides which ride in track portions, said guides include retractable pins which are retracted by the operation of a locking mechanism provided with said draw bar while said tracks include multiple locking detents for engagement with said retractable pins at a number of predefined positions along said track to enable positioning of the flexible material at those positions, such as in the case when the flexible material is a blind, these positions may further comprise fully extended, half extended and fully retracted positions.
