Fig. 11 is a plan view of a menstrual calendar according to Embodiment 5 of the present invention. DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be described in more detail with reference to the preferred embodiments illustrated in the attached drawings. Fig. 3 is a disassembled perspective view according to Embodiment 1, wherein a menstrual calendar is made based on 28 days, the menstrual period. The calendar is characterized in that, it comprises a base plate 10 on whose opposite surfaces a period displayer 11 is formed respectively, on which a menstrual period showing menstruation, a heeding period showing possible pregnancy, a viable period showing survival of sperm, and an ovulation period showing expected ovulation are displayed; round rotating plates 30, 30', on whose central portion, a transparent window 32 is formed respectively to be mounted on the period displayer 11 of said base plate 10 in such a manner that the period displayer 11 can be seen, and on whose peripheral surface, a date indicator 31 showing dates of lst~30th, 1st ~31st is formed respectively; and fixed pins 20, 20' which fix said rotating plates 30, 30' rotatively.
According to the menstrual calendar constructed as above mentioned, as shown in Fig. 1, if the menstruation of a woman begins on the 1st inst., she may set the 1st on the date indicator 31 to the beginning date of menstruation period formed on the base plate 10. Accordingly, the probable period of her pregnancy may be from 10th through 17th, and there is also a probability to be from 8th through 19th. In addition, if the period of her pregnancy for next month is to be estimated, she may turn the rotating plates 30, 30' round to set the 29th, the beginning day of the next menstruation, to the beginning date to estimate the period.
Fig. 7 is a disassembled perspective view according to Embodiment 2, wherein a calendar is made to be able to estimate the period optionally based on the individual menstrual period. The calendar is characterized in that, it comprises a base plate 10' on whose opposite surfaces a menstrual beginning indicator 1 and menstrual period displayer 2 of 24 ~ 32 days are formed respectively; round first rotating plates 40, 40' which are mounted on said menstrual beginning indicator 1 and said menstrual period displayer 2, and on whose surfaces, an expectant pregnancy period displayer 13 showing the heeding period, the viable period and ovulation period is formed, with the surface of other than said expectant pregnancy period displayer 13 being transparent, and a period indicator 12 in one direction is formed respectively; round second rotating plates 50, 50' which are mounted on said first rotating plates 40, 40', and on whose central portions, a transparent window 32 is formed respectively in such a manner that the menstrual period indicator 12 of said base plate 10' and each expectant pregnancy displayer 13 of said first rotating plates 40, 40' can be seen, and on whose peripheral surface, a date indicator 31 showing dates of 1st — 30th, 1st — 31st is formed respectively; and fixed pins 20, 20' which fix said first rotating plates 40, 40' and said second rotating plates 50, 50' rotatively.
According to the menstrual calendar constructed as above mentioned, as shown in Fig. 5, if the menstruation of a woman begins on the 1st inst., she may turn the first rotating plates 40, 40' round to set the period indicator 12 to the 28 days among 24-32 days of the menstrual period, and turn the second rotating plates 50, 50' round to set the 1st on the date displayer 31 to the menstrual beginning indicator 1 printed on the base plate 10'. Accordingly, the probable period of her pregnancy may be from 10th through 17th, and there is also a probability to be from 8th through 19th. In addition, if the period of her pregnancy for next month is to be estimated, she may turn the second rotating plates 50, 50' round to set the 29th, the beginning day of the next menstruation, to the menstrual beginning indicator 1. In case that the menstruation began on the 30th previous month and the last day of the month was the 31st, with the calendar on the rear surfaces of the base plates 10, 10' (refer to Fig, 2 and 6), the date of probable pregnancy can be estimated conveniently by opting the date between 30th and 31st attached discriminately on the opposite surfaces of the base plates 10, 10'. Only, in case of February when the days are 28 or 29, some amount of inconvenience must be tolerated.
The date estimation of the present invention is based on the nearest beginning date of menstruation, and it is the general conception that the period approximately from 24 days through 32 days before and after 28 days is regarded as normal, based on the medical materials such as Ogino's periodical method.
As described above, the present invention provides a menstrual calendar, based on a natural periodical technique, and enabling the estimation of the menstrual period and pregnant or contraceptive period conveniently as well as correctly, thus preventing various problems such as unwanted pregnancy beforehand, which is likely to be caused by incorrect estimation of menstrual period.
The present invention is not limited to the embodiments above described, but as shown in Fig. 5 and Fig. 10, it can be used one fixed pin considering cost and design in the manufacturing process of the product, and as shown in Fig. 11, it can also be used with separating lines drawn between the dates on the date displayer 31 to prevent the eπor of estimation.
The present invention relates to the problems that every women of probable pregnancy faces, can expect a high possibility of domestic and export demands, and can be used efficiently for various objects, for example, for an educational material in case of the size and material of the plates being varied differently.
