Abstract
Abstract A display assembly in the form of a supporting shell that mounts the assembly in an upright display panel in a matrix configuration. A disk assembly is pivoted to each shell and includes a thin disk movable about a transverse horizontal axis. The disk is moved by magnetic forces between a reflective position exposing one disk surface to the front of the panel, a closed condition exposing its opposite surface to the front of the panel, and a backlighted condition which is intermediate the other two.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A movable display assembly adapted for use in a spatial arrangement that includes a plurality of individually controlled assemblies, said display assembly comprising: an upright frame surrounding an open window; bearing means at opposite sides of the window on said frame along a transverse bearing axis; an armature pivotally mounted by said bearing means for angular movement relative to said frame about the bearing axis; a thin disk fixed to said armature, said disk having visually contrasting outer surfaces at opposite sides thereof; and means on said frame and armature for pivoting the armature and disk about the bearing axis between two or more alternate angular positions relative to the frame; said disk being removably mounted on said armature to one side of said armature axis by a pair of opposed slotted tabs releasably engaging opposite side edges of the disk, said tabs being in alignment with one another to one side of said armature axis; one tab being wider than the other; said disk having notches along opposed side edges thereof complementary in width to the respective tabs, whereby the disk is properly indexed on the armature by matching of the respective notches and tabs.
Claim 2
Dependent Claim
196 words
A movable display assembly adapted for use in a spatial arrangement that includes a plurality of individually controlled assemblies, said display assembly comprising: an upright frame surrounding an open window; bearing means at opposite sides of the window on said frame along a transverse bearing axis; an armature pivotally mounted by said bearing means for angular movement relative to said frame about the bearing axis; a thin disk fixed to said armature, said disk having visually contrasting outer surfaces at opposite sides thereof; and means on said frame and armature for pivoting the armature and disk about the bearing axis between two or more alternate angular positions relative to the frame; said disk being removably mounted on said armature to one side of said armature axis by a pair of opposed slotted tabs releasably engaging opposite side edges of the disk, said tabs being in alignment with one another to one side of said armature axis; one tab being wider than the other; said disk having notches along opposed side edges thereof complementary in width to the respective tabs, whereby the disk is properly indexed on the armature by matching of the respective notches and tabs.
Claim 3
Dependent Claim
48 words
A movable display assembly as set out in claim 1 wherein the disk is releasably gripped at its opposite side edges by a pair of opposed slotted tabs aligned along one side of said armature, one of the outer surfaces of the disk being unobstructed by said armature.
Claim 4
Dependent Claim
72 words
A movable display assembly as set out in claim 1 wherein the disk is releasably gripped at its opposite side edges by a pair of opposed slotted tabs aligned along one side of said armature, one of the outer surfaces of the disk being unobstructed by said armature; the remaining outer surface of the disk, as well as the armature and frame all having a common background color about their areal surfaces.
Claim 5
Dependent Claim
83 words
A movable display assembly as set out in claim 1 wherein the disk is releasably gripped at its opposite side edges by a pair of opposed slotted tabs aligned along one side of said armature, one of the outer surfaces of the disk being unobstructed by said armature; the remaining outer surface of the disk, as well as the armature and frame all having a common background color about their areal surfaces; and light means spaced behind the frame for backlighting the disk.
Claim 6
Dependent Claim
171 words
A movable display assembly adapted for use in a spatial arrangement that includes a plurality of individually controlled assemblies, said display assembly comprising: an upright frame surrounding an open window; bearing means at opposite sides of the window on said frame along a transverse bearing axis; a substantially linear armature extending between said bearing means and pivotally supported thereby for angular movement relative to said frame about the bearing axis; a thin disk fixed to said armature, said disk having a reflective surface and a background surface which are visually contrasting at opposite sides thereof; and means on said frame and armature for pivoting the armature and disk about the bearing axis between two or more alternate angular positions relative to the frame; said armature having two opposed slotted tabs near its ends for releasably engaging the disk in a position offset from the transverse bearing axis; said tabs being received in notches along opposed sides of the disk leaving the remainder of the reflective surface uncovered for maximum light reflection.
Claim 7
Dependent Claim
171 words
A movable display assembly adapted for use in a spatial arrangement that includes a plurality of individually controlled assemblies, said display assembly comprising: an upright frame surrounding an open window; bearing means at opposite sides of the window on said frame along a transverse bearing axis; a substantially linear armature extending between said bearing means and pivotally supported thereby for angular movement relative to said frame about the bearing axis; a thin disk fixed to said armature, said disk having a reflective surface and a background surface which are visually contrasting at opposite sides thereof; and means on said frame and armature for pivoting the armature and disk about the bearing axis between two or more alternate angular positions relative to the frame; said armature having two opposed slotted tabs near its ends for releasably engaging the disk in a position offset from the transverse bearing axis; said tabs being received in notches along opposed sides of the disk leaving the remainder of the reflective surface uncovered for maximum light reflection.
Claim 8
Dependent Claim
27 words
The movable display assembly of claim 5 wherein said armature further comprises an integrally formed stub at each end for being pivotally received in the bearing means.
Claim 9
Dependent Claim
21 words
The movable display assembly of claim 6 wherein said armature further comprises means for holding a cylindrical magnet at one end.
Claim 10
Dependent Claim
44 words
The movable display assembly of claim 5 wherein said armature further comprises a projection near the center thereof on the side of the armature adjacent to the disk for producing a curvature in the disk providing greater visibility from a wide range of angles.
Claim 11
Dependent Claim
60 words
The movable display assembly of claim 5 wherein said disk is asymmetrically divided into first and second disk ends by the transverse bearing axis; said first disk end having smaller widths and lengths than the second disk end thereby allowing the disk to be easily inserted between the tabs on the armature when the first disk end is inserted first.
