Abstract
Abstract In a calendar book each page corresponds to a part of a month and is subdivided into a plurality of fragments corresponding to the different parts of the month. The fragments of a page are releasably secured to each other for ready separation. The separated fragments of the pages may be successively removed from the stack as time ensues for continuously revealing the current date and the successive dates next-following beyond the dates of the next-to-be-overturned fragment.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A calendar book having a plurality of pages hingedly connected to each other by a hinge means, each page bearing delineations corresponding to a part of a month and being subdivided into a plurality of segments each corresponding to a different portion of the month, the segments of a page being releasably secured to each other for ready separation from each other, each segment being separately hingedly connected to the book by the hinge means, all adapted and arranged whereby the segments of the pages may be selectively and successively separated from the plurality of pages as time ensues for continuously revealing the current date and the successive dates next-following beyond the dates of the next-to-be-overturned fragment.
Claim 2
Dependent Claim
117 words
A calendar book having a plurality of pages hingedly connected to each other by a hinge means, each page bearing delineations corresponding to a part of a month and being subdivided into a plurality of segments each corresponding to a different portion of the month, the segments of a page being releasably secured to each other for ready separation from each other, each segment being separately hingedly connected to the book by the hinge means, all adapted and arranged whereby the segments of the pages may be selectively and successively separated from the plurality of pages as time ensues for continuously revealing the current date and the successive dates next-following beyond the dates of the next-to-be-overturned fragment.
Claim 3
Dependent Claim
38 words
In the calendar book of claim 1, the days of the segments showing the parts of one month being color coded differently from the days of the segments showing the parts of the next succeeding or preceding month.
Claim 4
Dependent Claim
37 words
In the calendar book of claim 1, the days of the segments showing the parts of one month being framed differently from the days of the segments showing the parts of the next succeeding or preceding month.
Claim 5
Dependent Claim
62 words
In the calendar book of claim 1, the days of the segments showing the parts of one month being identified by the name of the month delineated by one type style for distinguishing from the days of the segments showing the parts of the next succeeding or preceding month identified by the name of the month delineated by a distinguishing type style.
Claim 6
Dependent Claim
37 words
In the calendar book of claim 1, the days of the segments showing the parts of one month being shaded differently from the days of the segments showing the parts of the next succeeding or preceding month.
Claim 7
Dependent Claim
113 words
A calendar book having the months delineated on a stack of oppositely facing pages representative of the months, each page being arranged in calendar segments each bearing delineations representative of a portion of the month, the calendar segments being arranged to be overturned successively and independently of each other whereby as one calendar segment is overturned a calendar segments of the next succeeding month is revealed so that a number of days beyond those delineated on the next-to-be-overturned segment are available for ready viewing, the pages of the stack being hingedly connected to each other by a hinge means, and the segments of each page being separately hingedly connected by the hinge means.
Claim 8
Dependent Claim
113 words
A calendar book having the months delineated on a stack of oppositely facing pages representative of the months, each page being arranged in calendar segments each bearing delineations representative of a portion of the month, the calendar segments being arranged to be overturned successively and independently of each other whereby as one calendar segment is overturned a calendar segments of the next succeeding month is revealed so that a number of days beyond those delineated on the next-to-be-overturned segment are available for ready viewing, the pages of the stack being hingedly connected to each other by a hinge means, and the segments of each page being separately hingedly connected by the hinge means.
Claim 9
Dependent Claim
95 words
In a calendar having a plurality of separate pages representing particular time periods, the pages being hingedly arranged as a stack of hinged-together pages, each page being subdivided into a plurality of calendar fragments separable from each other along score lines, each fragment being turnable along the hinge line and being separately hingedly connected to the stack, the pages and the calendar fragments of the pages being in substantial alignment so that the overturning of an uppermost calendar fragment reveals the next-underlying calendar fragment therebelow with an additional array of next-following days of the calendar.
Claim 10
Dependent Claim
95 words
In a calendar having a plurality of separate pages representing particular time periods, the pages being hingedly arranged as a stack of hinged-together pages, each page being subdivided into a plurality of calendar fragments separable from each other along score lines, each fragment being turnable along the hinge line and being separately hingedly connected to the stack, the pages and the calendar fragments of the pages being in substantial alignment so that the overturning of an uppermost calendar fragment reveals the next-underlying calendar fragment therebelow with an additional array of next-following days of the calendar.
Claim 11
Dependent Claim
137 words
A calendar book comprised of a stack of pages bound to each other by a spiral binding for facilitating overturning of each page relative to the stack, each page having delineated thereon a plurality of date display areas corresponding to certain successive days of the calendar year and being subdivided into a plurality of sections, each section representing a portion of the date display areas of the page, the sections of each page being releasably secured to each other for ready detachment, each section being separately hingedly connected to the stack by a portion of the spiral binding, all adapted and arranged whereby sections of the pages may be successively overturned relative to the stack as time ensues for continuously revealing the current date and the next successive dates therefollowing beyond the dates of the next-to-be-overturned section.
