Abstract

A human reproduction indexing device for indicating the calendar dates for days of a menstrual cycle on which the probability of conception is the greatest includes a generally circular base member having indicia representing the calendar dates for the days of a given month disposed around the periphery thereof, and an index member rotatably secured to the base member and having an index and an indicator disposed thereon and configured so that when the index is aligned with the calendar date corresponding to the day of the onset of the menses, the indicator is positioned to indicate the calendar dates for a seven day interval starting ten days after the indexed date thereby indicating the time interval during which ovulation should occur and thus the days on which the probability of conception are the greatest.

Claims

1. An indexing device comprising:

a base member having calendar indicia representing the calendar dates for the days of one month interval disposed on at least one surface thereof, and an index member having indexing means including an indexing portion and an indicator portion, said index member being assembled together with said base member and being movable relative thereto to permit said indexing portion to be selectively aligned with said calendar indicia, said indicator portion being disposed in a predetermined relationship relative to said indexing portion whereby when said index member is set with said indexing portion aligned with a given one of the calendar indicia, said indicator portion is located to indicate a preselected group of the calendar dates.

2. An indexing device as set forth in claim 1 wherein said indicia representing the calendar dates includes a plurality of numerals each representing a different one of the days of the month, said numerals being disposed in a single circular track on said surface of said member, and wherein said indexing portion is in the shape of an arcuate segment of a predetermined number of angular degrees to thereby indicate a different preselected group of said numerals for different settings of said index member.

3. An indexing device as set forth in claim 2 wherein one edge of said indicator segment is located a preselected number of angular degrees from said indexing portion to thereby define an interval of a predetermined number of days between the calendar date indexed by the indexing portion and one of the calendar dates represented by the group of numbers indicated by said indicator segment.

4. An indexing device as set forth in claim 1 wherein said base member is circular in shape, said index member having a generally cylindrical main body portion extending through a central opening of said base member with a forward surface located adjacent to said indicia bearing surface of said base member and bearing said indexing means on a surface thereof, said index member having a flange portion adjacent to a rearward surface thereof and having means formed therewith for movably securing said index member to said base member.

5. A human reproduction indexing device for indicating the calendar dates for the days of a menstrual cycle on which the probability of conception is the greatest, said indexing device comprising:

a base member having calendar indicia representing the calendar dates for the days of at least one month disposed in a single circular track on at least one surface thereof, and an index member having indexing means including an indexing portion and an indicator portion said index member being assembled together with said base member for rotatable movement relative thereto to permit said indexing portion to be selectively aligned with the indicia representing each of said calendar dates, and said indicator portion being disposed in a predetermined relationship relative to said indexing portion whereby when said index member is set to align said indexing means with the calendar day corresponding to the start of the mensus, said indicator portion is located to indicate the calendar dates for a set of calendar days on which the probability of conception is the greatest.

6. An indexing device as set forth in claim 5 wherein said index member overlies said calendar indicia on said base member and has at least one cut out portion defining said indexing means for selectively exposing to view each of said calendar dates and the corresponding set of calendar dates.

7. An indexing device as set forth in claim 5 wherein said calendar indicia are disposed on said base member in a linear scale.

8. An indexing device as set forth in claim 7 wherein said base member is a generally flat rectangular member, said index member being in the form of a generally rectangular envelope, open-ended at both ends with said base member extending therethrough.

9. An indexing device as set forth in claim 5 in which said base member and said index member are each of a flat generally circular configuration, and including means extending through the centers of said circular members securing said members together.

10. An indexing device as set forth in claim 5 wherein said index member has a circular surface disposed adjacent to said indicia bearing surface of said base member with indexing means being disposed on said surface of said index member and wherein said indexing portion defines an arcuate segment of a predetermined number of angular degrees to thereby indicate a preselected number of calendar dates for each setting of said index member.

11. An indexing device as set forth in claim 10 wherein one edge of said indicator segment is located a preselected number of angular degrees from said indexing means to thereby define an interval of a predetermined number of days between the calendar date indexed by said indexing means and one of the calendar dates indicated by the indicator segment.

12. An indexing device as set forth in claim 5 wherein said calendar indicia represent the calendar dates for a thirty-one day month, and wherein said base member includes further calendar indicia representing the calendar dates for a thirty day month disposed on a further surface thereof and said index member having further indexing means including an indexing portion and an indicator portion for selectively indexing each of said calendar dates of said further calendar indicia with the calendar dates of said further calendar indicia.

13. A human reproduction indexing device for indicating the calendar dates for days of a menstrual cycle on which the probability of conception is the greatest, said indexing device comprising:

an annularly shaped base member having indicia representing calendar dates for days for at least a one month interval disposed on at least one surface thereof in a circular track, an indexing member movably secured to said base member for rotation relative thereto about an axis extending perpendicular to the center of said base member, said indexing member having indexing indicia disposed on a surface thereof, which is located adjacent to said indicia bearing surface of said base member, said indexing indicia including an index portion and an indicator portion defining an arcuate segment of preselected number of angular degrees to thereby indicate a preselected number of days, and one edge of said segment being located a preselected number of angular degrees away from said indexing means whereby when said indexing member is positioned with said indexing means aligned with the calendar day corresponding to the start of menses, said indicator means is located to indicate the calendar dates for the days of a menstrual cycle on which the probability of conception is the greatest.

14. An indexing device as set forth in claim 13 wherein said indicator segment indicates a different set of seven of said calendar dates for each of said calendar dates as indexed by said index portion.

15. An indexing device as set forth in claim 14 wherein said indicator segment indicates the calendar days for the tenth through seventeenth days following the calendar date indexed by said index portion.

16. A human reproduction indexing device for indicating the calendar dates for days of a menstrual cycle on which the probability of conception is the greatest, said indexing device comprising:

an annularly shaped base member having indicia representing calendar days for at least a one month interval disposed on a surface thereof, said indicia including a plurality of numerals each representing a different day of the month disposed in an equal spaced relationship in a circle adjacent to the peripheral edge of said base member, and an index member having a generally cylindrical main body portion extending through a central aperture of said base member, receptor means formed integrally with one of said members and engaging means formed integrally with the other one of said members for engagement with said receptor means to secure said members together with said index member being rotatably relative to said base member about an axis extending perpendicular to the surface of said base member, spring means positioned in said receptor means and engageable with said engaging means to provide frictional engagement between said receptor and said engaging means, said index member having indexing means disposed on a surface of its central body portion and indicator means disposed in said surface, said indicator means defining an arcuate segment of a preselected number of angular degrees to thereby indicate a preselected number of calendar days, one edge of said segment being spaced from said indexing means by a preselected number of angular degrees whereby when said index member is positioned with said indexing means aligned with the calendar day corresponding to start the mensus, said indicator means is located to indicate the calendar dates for the days of a menstrual cycle on which the probability of conception is the greatest.
