Abstract
An index system using single axis or multiple axes with single and multiple leaves turning around this axis (axes). All leaves or groups of leaves present an exposed marginal portion obtained by relative extension of leaves and/or partial removal of a portion of the marginal portion (s), which provides an overview of the content, which is indexed in groups and subgroups. Use is made of brief descriptions, capital letters, numbers, arrows and distinctive background color for facilitating the use of the index system.
Claims33
A booklet having an indexing system comprising:
- a cover, constituted from a left cover and a right cover, between which a folding line defining a first axis is provided;
- at least two leaves attached to said cover along said first axis, being a first or left leaf and a second or right leaf, each of said leaves having a front face and a back face on which printed matter is disposed;
- said at least two leaves each having an upper edge, a lower edge, and a side edge, each of said leaves being of substantially the same dimensions;
- said at least two leaves being axially displaced along said first axis relative to each other, such that when one of said leaves overlays the other underlying one of said leaves, the top and bottom edges of said respective leaves are not congruous, revealing a margin portion of said underlying one of said leaves;
- indexing means being located on said margin portion of each face of each of said leaves, said indexing means for both the first leaf and the second leaf being viewable when said first leaf and second leaf lie respectively one to the left and one to the right of said folding line, when said first leaf and second leaf are both turned to lie to the right of said folding line and when said first leaf and second leaf are both turned to lie to the left of said folding line;
- said indexing means being related to said printed matter provided on the face of the said leaf of which said margin portion, bearing said indexing means, forms a portion;
- and
- said printed matter and said indexing means being identically oriented for easy reading.
A booklet having an indexing system comprising:
- a cover, constituted from a left cover and a right cover, between which a folding line is provided;
- at least two leaves attached to said cover, being a first or left leaf and a second or right leaf, each of said leaves having a front face and a back face on which printed matter is disposed;
- said at least two leaves sharing a substantially common first axis of rotation with each other and with said cover, each of said leaves having an upper edge, a lower edge, and a side edge, a portion of said top edge of said leaves, the bottom edge of said leaves and the side edge of said leaves, but less than the whole of all of said sides, being congruous when any said leaf lies on any other said leaf;
- each of said leaves being provided with a first cut with a side edge and a top edge in each leaf, said first cut revealing a margin portion of an underlying leaf when said leaves are turned to a first side of said folding line, and each of said leaves being provided with a second cut with a side edge and a bottom edge in each leaf, said second cut revealing a margin portion of an underlying leaf when said leaves are turned to a second side of said folding line;
- said revealed margin portion containing indexing means related to said printed matter provided on the face of said leaf of which said revealed margin portion, bearing indexing means, forms a portion;
- and
- said printed matter and said indexing means being identically oriented for easy reading.
The booklet of claim 11, wherein said printed material is compartmentalized in groups and subgroups, said indexing means identifying said groups and sub-groups.
A booklet having an indexing system comprising:
- a cover, constituted from a left cover and a right cover, between which a folding line defining an axis is provided;
- a plurality of leaves attached to said cover, each of said leaves having a front face and a back face on which printed matter is disposed, each of said leaves having an upper edge, a lower edge and a side edge, each of said leaves being of substantially the same dimensions;
- at least two leaves of said plurality of leaves sharing a substantially common first axis of rotation with each other, and a third leaf of said plurality of leaves having a second axis of rotation parallel to but at a distance from said first axis of rotation, said at least two leaves forming a first set of leaves and said third leaf forming the first leaf of a second set of leaves;
- a visible portion being revealed on an uppermost leaf of one of said sets of leaves when underlying an other of said sets of leaves, said visible portion being effected by the displacement between the axis of rotation of the first set and the axis of rotation of the second set, on which visible portions of said first set and said second set a first indexing means being provided, said first indexing means being
- related respectively to said printed matter provided on the face of the leaf or leaves of said first and second sets;
- and
- said printed matter and said first and second indexing means being identically oriented for easy reading.
An index system as claimed 25, further comprising revealing means including a cut with side edge and a top or bottom edge, said cut revealing indexing means positioned on a marginal portion of at least one underlying leaf, said indexing means being related to said printed matter provided on the face of the leaf of which said revealed margin portion, bearing indexing means, forms a portion.
The booklet of 25, wherein said indexing means comprise a brief description.
