Description
F- F. S. SIEVE DESK CALENDAR July 2, 1957 Filed Jan. 30, 1956 INVENTOR FksoaA E S, S15v5 United States Patent 2,797,512 DESK CALENDAR Fredda F. S. Sieve, New York, N. Y.
Application January 30, 1956, Serial No. 562,283 1 Claim. (Cl. 40-107) This invention relates to an improvement in dodecahedron desk calendars.
"It is one of the objects of the invention to provide a dodecahedron desk calendar which will be more convenient to use and easier to manufacture than previous dodecahedron type calendars.
Another object of the invention is to provide a dodecahedron calendar in which the first six months of the year appear on the upper half of the dodecahedron and the latter six months on the lower half of the dodecahedron, whereby dates for the first six months may be read without turning the calendar over and dates for the last six months may likewise be read without turning the calendar over when the position of the calendar has been changed so that the lower half with dates for the latter half of the year is uppermost. Thus it is necessary to turn the calendar over only once during the year.
Another object of the invention is to simplify the manufacture of dodecahedron desk calendars by providing a dodecahedron desk calendar which can be made in two parts of plastic material and the two parts cemented together to provide a complete regular dodecahedron with twelve regular pentagonal sides.
Another object of the invention is to provide a hollow dodecahedron desk calendar with weighting material on the inside thereof whereby the calendar will remain in whatever position it may be placed due to the fiat side it rests upon and due to the weighting material.
Various other objects and advantages of my invention will appear as this description proceeds.
Referring now to the drawings which illustrate a preferred form of embodiment of my invention,
Fig. 1 illustrates a top plan view of the calendar showing the first six months of the year on the top portion of the calendar;
Figure 2 illustrates a bottom plan view of the calendar showing the last six months of the year on the bottom;
Fig. 3 is a side view partially broken away showing a portion of the calendar as it appears from the side; and
Fig. 4 is a perspective view of one-half of the molded dodecahedron.
As illustrated in Fig. 1, the dodecahedron desk calendar A has the month of January on the top thereof, the month of February on face 2, March on face 3, April on face 4, May on face 5, June on face 6, and as shown in Fig. 2, the month of July is on face 7, August on face 8, September on face 9, October on face 10, November on face 11, and December on the top 12. By this arrangement any month in the first half of the year may be read conveniently by merely rotating the calendar to the proper position and as illustrated in Fig. 3 it is possible to read two consecutive months of the calendar from the side view. By turning the dodecahedron over so that the month of January is on the bottom and the month of December on top, any month in the second half of the year may be read conveniently by merely rotating the calendar to the proper position.
Patented July 2, 1957 Each face of the calendar is composed of a regular pentagon and the calendar is produced by a plastic molding operation in which sides 1 to 6 as indicated in Fig. 4 are molded in one integral piece and similarly sides 7 to 12 are molded in one integral piece with a calendar of one month of the year molded in each of the twelve faces so that when the two halves of the calendar are brought together and cemented or otherwise secured along the lines B in Fig. 3 a regular dodecahedron is produced from the two parts of plastic molded material.
Before securing the two parts together a shiftable weighting material C which may be sand, shot, liquid or any other desired weighting material, is preferably placed inside one half of the molded calender. After the two halves of the calendar have been secured together the shiftable weighting material will shift to the bottom half of the calendar as the position of the calendar is changed to give it the necessary weight to maintain it in position. If desired, a weighting material may be permanently secured in the top and bottom halves of the calendar and the shiftable weighting material omitted.
The edges D of the meeting halves of the molded plastic material are preferably bevelled as indicated, so as to provide a wider joining surface to facilitate cementing or otherwise securing the two halves of the calendar together and to provide a wider meeting face for the two halves while they are being assembled together. Any suitable adhesive such as a thermosetting or thermoplastic resin may be used to secure the two halves of the dodecahedron or they may be secured by heat and pressure without an additional adhesive if the plastic material is of such a nature that it may be fused together by heat and pressure.
While I have described a specific form of embodiment of my invention, it will be understood that various modifications and changes may be made therein without departing from the spirit of the invention or the scope of the following claim:
I claim.
As an article of manufacture a calendar comprising a regular dodecahedron having twelve planar faces, each in the shape of a regular pentagon and having a calendar for one month of the year on each pentagonal face with the horizontal lines of each monthly calendar parallel to one edge of the pentagonal face on which it appears, said calendar having the first six months of the year on the six pentagonal faces on one half of the dodecahedron and the last six months of the year on six pentagonal faces on the other half of the dodecahedron and having five consecutive months in the first half of the year on adjacent pentagonal faces, said five consecutive months having the horizontal lines of the monthly calendars parallel to the plane of the pentagonal face on which the calendar for remaining month of the first half of the year is placed, said calendar having five consecutive months in the last half of the year on adjacent pentagonal faces and having the horizontal lines of the monthly calendars parallel to the plane of the pentagonal face on which the calendar for the remaining month of the last half of the year is placed, whereby a plurality of said adjacent months can be read in one position of the calendar.
