Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
A mounting device for displaying pictures in a random sequence, comprising: a first picture set holder including at least one transparent picture sheet having at least one picture for display, a first carrier member and first means pivotally mounting said at least one transparent picture sheet to one edge of said first carrier member; a second picture set holder for holding at least two pictures for display, said second picture set holder including at least two transparent picture sheets having at least one picture on each of said picture sheets for display, and a second carrier member, said first mounting means pivotally mounting said at least two transparent picture sheets to one edge of said second carrier member, for rotation about a common pivot axis through an angle of substantially 360° about said common pivot axis; and second means pivotally mounting said first and second carrier members to each other at their respective opposite edges from said one edge of each said carrier member for movement relative to a display area border of said first picture set holder such that any of said at least two picture sheets is selectively superimposable on said at least one transparent picture sheet of said first picture set holder.
Claim 2
Dependent Claim
205 words
A mounting device for displaying pictures in a random sequence, comprising: a first picture set holder including at least one transparent picture sheet having at least one picture for display, a first carrier member and first means pivotally mounting said at least one transparent picture sheet to one edge of said first carrier member; a second picture set holder for holding at least two pictures for display, said second picture set holder including at least two transparent picture sheets having at least one picture on each of said picture sheets for display, and a second carrier member, said first mounting means pivotally mounting said at least two transparent picture sheets to one edge of said second carrier member, for rotation about a common pivot axis through an angle of substantially 360° about said common pivot axis; and second means pivotally mounting said first and second carrier members to each other at their respective opposite edges from said one edge of each said carrier member for movement relative to a display area border of said first picture set holder such that any of said at least two picture sheets is selectively superimposable on said at least one transparent picture sheet of said first picture set holder.
Claim 3
Dependent Claim
