Abstract
Abstract A booklike toy which can be opened to display up to four different stage settings, each setting including a pair of walls at right angles and a floor. The toy is formed from a single sheet of thin cardboard formed with a plurality of successive page portions positioned in a row and separated by folding lines for folding, accordion style, into a book. The sheet also includes platform portions, each extending laterally from a page portion, a pair of adjacent platform portions glued together in a lap joint so they lie taut when the adjacent pages are opened to a 90* angle. The sheet also includes a pair of cover portions with a spine strip between them, the first and second cover portions respectively glued to a first and last of the pages to create a hard-cover book appearance.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A toy device for unfolding from a book shape into stage settings comprising: a sheet having at least two successive page portions separated by folding lines, and said sheet also having a platform extending between a pair of adjacent page portions, each platform being of a length to extend tautly when the adjacent page portions between which the platform extends are opened to a predetermined angle, said platform having a fold line extending at an angle to substantially radiate from the folding line separating the pair of page portions between which the platform extends.
Claim 2
Dependent Claim
94 words
A toy device for unfolding from a book shape into stage settings comprising: a sheet having at least two successive page portions separated by folding lines, and said sheet also having a platform extending between a pair of adjacent page portions, each platform being of a length to extend tautly when the adjacent page portions between which the platform extends are opened to a predetermined angle, said platform having a fold line extending at an angle to substantially radiate from the folding line separating the pair of page portions between which the platform extends.
Claim 3
Dependent Claim
30 words
The toy described in claim 1 including first and second cover portions pivotally joined to each other and joined facewise to the first and last of said successive page portions.
Claim 4
Dependent Claim
34 words
The toy described in claim 2 wherein said first and second cover portions are joined by a spine strip, each side of said strip foldably joined to a different one of said cover portions.
Claim 5
Dependent Claim
40 words
The toy described in claim 1 wherein said platform includes first and second platform portions respectively contiguous with the first and second page portions between which the platform extends, said platform portions having regions adhesively joined facewise to each other.
Claim 6
Dependent Claim
57 words
The toy described in claim 1 wherein said platform includes a square platform portion contiguous with a first page portion and having a diagonal folding line therein, and a triangular platform portion contiguous with a second page portion and joined facewise to a portion of said square platform portion on one side of the folding line thereon.
Claim 7
Dependent Claim
120 words
A folding toy comprising: a unitary sheet having a plurality of successive portions, the first portion joined to the second portion by pivot means formed in said sheet and the second and succeeding portions separated by parallel folding lines in said sheet, the second of said portions joined facewise to the third portion, and succeeding pairs of portions joined facewise to each other to form foldably joined leaves of two-sheet thickness, and the first portion joined facewise to the last portion, said pivot means formed in said sheet comprising a spine portion of a width approximately equal to the combined thicknesses of said leaves and portions and having opposite sides joined by folding lines to said first and second portions.
Claim 8
Dependent Claim
120 words
A folding toy comprising: a unitary sheet having a plurality of successive portions, the first portion joined to the second portion by pivot means formed in said sheet and the second and succeeding portions separated by parallel folding lines in said sheet, the second of said portions joined facewise to the third portion, and succeeding pairs of portions joined facewise to each other to form foldably joined leaves of two-sheet thickness, and the first portion joined facewise to the last portion, said pivot means formed in said sheet comprising a spine portion of a width approximately equal to the combined thicknesses of said leaves and portions and having opposite sides joined by folding lines to said first and second portions.
Claim 9
Dependent Claim
21 words
The folding toy described in claim 6 wherein said spine portion has a folding line dividing it into two narrow parts.
Claim 10
Dependent Claim
38 words
The folding toy described in claim 6 wherein said first and second portions have tabs extending along at least some of their edges and folded over onto said first and second portions whereby to increase their apparent thickness.
Claim 11
Dependent Claim
41 words
The folding toy described in claim 6 wherein said sheet includes platform portions eXtending tautly between the lower edges of pairs of adjacent sheets when the sheets of the pair are opened to a predetermined angle which is less than 180*.
Claim 12
Independent Claim
95 words
A method for constructing a folding toy comprising: forming a sheet with successive leaf portions arranged in a row and with platform portions extending from one edge of at least some of said leaf portions; folding said sheet in alternate directions at the intersections of adjacent leaf portions; joining pairs of successive leaf portions facewise to each other; and joining said platform portions to portions of said sheet to extend tautly between adjacent pairs of said leaf portions which are not joined facewise to each other when they are pivoted apart to a predetermined angle.
Claim 13
Independent Claim
95 words
A method for constructing a folding toy comprising: forming a sheet with successive leaf portions arranged in a row and with platform portions extending from one edge of at least some of said leaf portions; folding said sheet in alternate directions at the intersections of adjacent leaf portions; joining pairs of successive leaf portions facewise to each other; and joining said platform portions to portions of said sheet to extend tautly between adjacent pairs of said leaf portions which are not joined facewise to each other when they are pivoted apart to a predetermined angle.
Claim 14
Dependent Claim
80 words
The method described in claim 10 wherein: said step of forming platform portions includes forming a first platform portion joined only to one of said leaf portions and a second platform portion joined only to another adjacent leaf portion; and said step of joining said platform portions includes joining a pair of said platform portions on said adjacent leaf portions to each other so that part of each platform portion overlaps part of the other and is fastened to it.
Claim 15
Dependent Claim
19 words
The method described in claim 10 including joining a first and last of said leaf portions in facewise adjacency.
