Abstract
Abstract A convertible carrying case and expandable essel is presented by a pair of three sided trays interconnected by a liner that includes two slidable panels engaged by the respective trays and an intermediate spine that encloses the open ends of the trays when they are closed on one another. A multi-position handle is provided on each tray to facilitate suspension and carrying of the closed trays as an enclosed case. They also provide separate adjustable supports for the two trays when they are in an open side-by-side positions as an expandable easel for displaying or viewing of articles positioned within the tray boundaries.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
A convertible carrying case and expandable easel, comprising: first and second three-sided trays, each tray having a bottom with oppositely facing inner and outer surfaces, the inner surface of each bottom being partially rimmed by three walls, the walls of the first and second trays having complementary peripheral edges adapted to abut one another when the trays are closed to form an enclosure that is open across one end; a liner having first and second rectangular panels hinged to a central spine along two parallel hinge axes, said first and second panels and said trays including cooperating means whereby said panels are slidably guided within the first and second trays, respectively, at positions in which the panels are adjacent to the inner surfaces of the tray bottoms for relative movement between them in the planes of the respective panels in directions perpendicular to the hinge axes; and foldable handle means movably mounted on at least one tray for suspending the trays and interconnecting liner while the trays are closed and for alternately supporting the trays in side-by-side positions across the inner while resting in upwardly-open, inclined positions.

Claim 3
Dependent Claim
57 words
The convertible carrying case and expandable easel of claim 1, wherein the walls of each tray include two parallel side walls extending across the width of its bottom and joined to a perpendicular end wall; the width of each panel being equal to or less than the width of each inner surface across the respective tray bottoms.
Claim 4
Dependent Claim
110 words
The convertible carrying case and expandable easel of claim 1, wherein the walls of each tray include two parallel side walls extending across the width of its bottom and joined to a perpendicular end wall; the width of each panel being equal to or less than the width of each inner surface across the respective tray bottoms; and locking means on the panels and trays for selectively positioning the panels relative to the tray engaged by it with the spine of the liner arranged across the open end of the enclosure formed by the two trays when folded together to a closed position about the hinge axes of the liner.
Claim 5
Dependent Claim
37 words
The convertible carrying case and expandable easel of claim 1 wherein the liner is constructed from a single sheet of material scored along parallel lines at each side of the spine to define said parallel hinge axes.
