Abstract
A gestation calendar for use by an expectant mother. A first disk has first indicia corresponding to days of a calendar year. A second disk is pivoted concentrically to the first disk and has second indicia defining successive weeks of a gestation term and associated information. The information includes imagined statements by a fetus representing its development during the time intervals, with corresponding information relating to prenatal health care for the mother. When the first and the second disks are positioned so that an index mark of the second indicia is aligned with a start date of the mother's last period in the first indicia, the development of the fetus at a certain date during pregnancy along with the corresponding prenatal health care information are conveyed by the information associated with that time interval which is aligned with the certain date in the first indicia.
Description




BACKGROUND OF THE INVENTION




1. Field of The Invention




This invention relates to calendar devices.




2. Discussion of The Known Art




A pregnancy “wheel” calendar available from Corometrics® Medical Systems Inc., North Wallingford, Conn., includes a rear disk with indicia along its circumference corresponding to months and days of a year; and a smaller, concentric front disk having a number of sectors corresponding to the weeks of a human gestation term. Certain numeric data is printed within the sectors to indicate a fetus's expected weight and length at the corresponding week.




U.S. Pat. No. 5,443,288 (Aug. 22, 1995) relates to a pregnancy advent calendar for informing a user of milestones of the fetal development process. The calendar includes an upper paper layer and a substrate paper layer. Rectangular tabs are cut in the upper layer to swing outward, and the tabs are labeled with numbers corresponding to the weeks of the gestation term. When a tab for a given week is lifted, a “message” from the fetus can be read.




U.S. Pat. No. 5,763,860 (Jun. 9, 1998) discloses a gestational calculator to fit in the pocket of a user. The calculator computes an expected due date based on an initial date corresponding to the first day of the expectant mother's last period. The calculator may also determine a gestational age based on the initial and the current dates, according to the patent.




There remains a need, however, for a calendar that allows an expectant mother to be informed concerning the state of development of the fetus at a desired date during pregnancy, together with any important prenatal health care measures to be taken by the mother on or around the desired date.




SUMMARY OF THE INVENTION




According to the invention, a gestation calendar for use by an expectant mother includes a first sheet material having first indicia corresponding to days of a calendar year. A second sheet material is mounted to the first sheet material for relative movement and has second indicia defining successive time intervals of a gestation term of a fetus and information associated with each of the time intervals.




The information includes imagined statements by the fetus representing its development during the time intervals defined by the second indicia, with corresponding information concerning prenatal health care for the mother. When the second sheet material is positioned to align an index mark of the second indicia with a start date of the expectant mother's last period in the first indicia, the state of development of the fetus at a certain date during the gestation term together with corresponding prenatal health care measures for the mother are conveyed by the information associated with that time interval which is aligned with the certain date in the first indicia.




For a better understanding of the invention, reference is made to the following description taken in conjunction with the accompanying drawing, and the scope of the invention will be pointed out by the appended claims.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

shows a gestation calender


10


according to the invention. Basically, the calendar


10


comprises a first piece of rigid sheet material or board


12


, e.g., paper cardboard or other suitable planar medium on which text and other indicia may be printed or displayed. In the present embodiment, the first board.


12


is formed as a circular disk on which first indicia


14


are printed over a portion of the first board in the region of the outer periphery or circumference of the board


12


. The first indicia correspond to the days of a calender year, and each of the twelve months of the year are labeled within corresponding sectors


16


which subtend arcs of substantially the same length about the circumference of the first board


12


. Within each of the month-sectors


16


, the days of a particular month are represented by scale marks


18


which are numbered, for example, every five days of the particular month.




The calendar


10


also includes a second piece of rigid sheet material or board


22


made from paper cardboard or equivalent planar medium on which text and other indicia may be printed or displayed. In the disclosed embodiment, the second board


22


is also in the form of a circular disk having a diameter less than that of the first board


12


. The second board


22


is mounted to the first board for rotational movement with respect to the first board. For example, the second board


22


is pivoted at its center concentrically to the first board


12


by a conventional fastening member


24


that passes through the centers of both of the boards


12


,


22


.




The second board


22


has second indicia


26


over a portion of the board


22


that subtends an arc corresponding to the ratio of a human gestation term of, e.g., forty-one weeks to a total fifty-two weeks of a year. In the disclosed embodiment, the second indicia


26


define the forty-one successive weeks by correspondingly numbered week-scale marks


28


that extend radially through a portion of the circumference of the second board


22


. The first indicia


14


on the first board


12


, and the second indicia


26


on the second board


22


, are dimensioned and arranged so that when the second board


22


is rotated relative to the first board


12


, an index mark


30


at a beginning of the second indicia can be aligned with a date within the first indicia


14


which date is the start date of an expectant mother's last period. In the illustrated embodiment, the index mark


30


is aligned with the date May


24


.




The second indicia


26


also define, between the week-scale marks


28


and the center of the board


22


, a number of sectors


32


corresponding to each of the weeks numbered by the marks


28


. Text of imagined statements by the fetus representing its state of development during each time interval (week) defined by the second indicia, are printed within the sectors


32


. Some statements are partially shown within the sectors


32


in

FIG. 1

, and a full set of such statements are given in the table further below. At least some of the text relates to important prenatal e measures to be taken by the expectant mother on or corresponding time intervals during pregnancy.





FIG. 2

is an enlarged view of the calendar in

FIG. 1

which corresponds to the beginning of the term of gestation. Thus, the imagined statements begin within the third week following the start date (May 24) of the mother's last period with, “Probable day I started.”

FIG. 3

is an enlarged view of that portion of the calendar


10


in

FIG. 1

that corresponds to the end of the gestation term. The statement within the sector


32


corresponding to the forty-first week reads, “I promise, I'm coming”.




The following table sets out examples of statements for each of weeks 3-41 which may appear in the corresponding sectors


32


.

22


is positioned to align its index mark


30


with a start date of the expectant mother's last period in the first indicia


14


on the first board


12


. The state of the fetus at a certain date during pregnancy along with any corresponding prenatal health steps for the mother, are conveyed by the text within that sector


32


which is aligned with the certain date in the first indicia


14


. For example, in the illustrated embodiment, during the fifth week of gestation the mother is instructed to see her obstetrician of midwife.
