Claim 3

An enclosure assembly according to claim 1 wherein each of said panels comprises a generally rectangular slat of stiff transparent polymeric material, said means attaching the edge portions of said lengths of flexible material to said adjacent panels comprises strips of wood on the side of said edge portions opposite said slats, and said lengths of flexible material are transparent polymeric material.

Claim 4

An enclosure assembly according to claim 1 wherein all of said panels have widths in the range of about ten to fourteen inches.

Claim 5

An enclosure assembly according to claim 1 wherein all of said lengths of non porous flexible material have widths in the range of about two to five inches.

Claim 6

An enclosure assembly according to claim 1 wherein said panels comprise thermal insulating material.

Claim 7

An enclosure assembly according to claim 1 wherein the adjacent edges of said panels are shaped to make tongue and groove-like engagement with each other.

Claim 8

An enclosure according to claim 1 wherein said means for affording movement of said panels from said closed to said open positions comprises a spindle mounted adjacent the top of said frame for rotation about a generally horizontal axis, said spindle having only two opposite axially extending support edges each about equally spaced from opposite sides of the axis, means for attaching the uppermost edge of the uppermost of said panels to said spindle, and manually actuatable means for rotating said spindle to wrap said panels and lengths of flexible material around said support edges, said means for attaching, the widths of the panels, and the widths of the lengths of flexible material being adapted to position said lengths of flexible material around said support edges and said panels between said support edges generally parallel to each other as said panels and lengths of flexible material are wound around said spindle.

Claim 9

An enclosure assembly according to claim 1 further including a piece of screen attached to said frame entirely across said through opening at a position spaced from and generally parallel to said guide means.

Claim 10

An enclosure assembly comprising: a plurality of stiff elongate generally rectangular panels having parallel longitudinal panel edges, generally uniform widths between said panel edges, and major side surfaces; a frame defining a central through opening, having a top, guide means for positioning panels disposed across said opening one above another in edge-to edge relationship and for affording edgewise movement of said panels along said guide means through said top in a direction generally normal to said panel edges, and support means for supporting the lowermost panel of a stack of adjacent panels across said opening; a plurality of elongate, generally rectangular lengths of flexible non porous material having generally uniform widths, each of said lengths of flexible material having opposite parallel longitudinal edges and edge portions adjacent said edges; means along the adjacent edges of each pair of adjacent panels attaching the edge portions of a different one of said lengths of flexible material along corresponding side surfaces of said adjacent panels with the edges of the flexible material adjacent the edges of the adjacent panels to form the length of flexible material into a generally cylindrical projection from said corresponding side surfaces when the uppermost one of said adjacent panel edges is supported on the other, said lengths of flexible material being tensioned around and between said means for attaching along the panel edges of said adjacent panels and having widths that cause little relative movement of said panels away from each other when said uppermost panel is lifted in said guide means; and means for affording movement of said panels relative to said frame from a closed position with said panels covering said opening and supported one above the other on said support means, and an open position with all of said panels lifted above said opening comprising a spindle mounted adjacent the top of said frame for rotation about a generally horizontal axis, said spindle having only two opposite axially extending support edges each about equally spaced from opposite sides of the axis, means for attaching the uppermost edge of the uppermost of said panels to said spindle, and manually activatable means for rotating said spindle to wrap said panels and lengths of flexible material around said support edges, said means for attaching, the widths of the panels, and the widths of the strips of flexible material being adapted to position said lengths of flexible material around said support edges and said panels between said support edges generally parallel to each other as said panels and lengths of flexible material are wound around said spindle.

Claim 11

An enclosure assembly comprising: a plurality of stiff elongate generally rectangular panels having parallel longitudinal panel edges, generally uniform widths between said panel edges, and major side surfaces; a frame defining a central through opening, having a top, guide means for positioning panels disposed across said opening one above another in edge-to edge relationship and for affording edgewise movement of said panels along said guide means through said top in a direction generally normal to said panel edges, and support means for supporting the lowermost panel of a stack of adjacent panels across said opening; a plurality of elongate, generally rectangular lengths of flexible non porous material having generally uniform widths, each of said lengths of flexible material having opposite parallel longitudinal edges and edge portions adjacent said edges; means along the adjacent edges of each pair of adjacent panels attaching the edge portions of a different one of said lengths of flexible material along corresponding side surfaces of said adjacent panels with the edges of the flexible material adjacent the edges of the adjacent panels to form the length of flexible material into a generally cylindrical projection from said corresponding side surfaces when the uppermost one of said adjacent panel edges is supported on the other, said lengths of flexible material being tensioned around and between said means for attaching along the panel edges of said adjacent panels and having widths that cause little relative movement of said panels away from each other when said uppermost panel is lifted in said guide means; and means for affording movement of said panels relative to said frame from a closed position with said panels covering said opening and supported one above the other on said support means, and an open position with all of said panels lifted above said opening comprising a spindle mounted adjacent the top of said frame for rotation about a generally horizontal axis, said spindle having only two opposite axially extending support edges each about equally spaced from opposite sides of the axis, means for attaching the uppermost edge of the uppermost of said panels to said spindle, and manually activatable means for rotating said spindle to wrap said panels and lengths of flexible material around said support edges, said means for attaching, the widths of the panels, and the widths of the strips of flexible material being adapted to position said lengths of flexible material around said support edges and said panels between said support edges generally parallel to each other as said panels and lengths of flexible material are wound around said spindle.
