JOEL WEISSMAN ATTORNEYS CUBE CALENDAR Conventional calendars which utilize cubes having indicia marked on their sides have heretofore been limited to using the cubes to indicate only the date. This is accomplished by marking numerical indicia on the sides of the cubes and arranging the cubes so that their outwardly facing sides indicate the correct date. Other devices are used in conjunction with the date marked calendar cubes to indicate the month and day. One reason that a calendar composed solely of cubes has not been developed is the limitation imposed by a cube having six sides which permits only 6 months of the year to be marked on a month marked cube and 6 days of the week to be marked on a day marked cube.

It is accordingly an object of this invention to provide an all cube calendar which indicates day, month and date information.

It is a further object of this invention to provide a holder for the calendar cubes which permits only a single month and a single day to appear on the outwardly facing sides of the cubes.

It is a further object of this invention to provide a cube calendar having a cube marked with all the months of the year.

It is a further object of this invention to provide a cube calendar having a cube marked with all the days of the week.

This invention provides a cube calendar which includes a plurality of cubes having day, month and date indicia marked on their sides and a holder for the cubes. The month marked cube has two months of the year marked on each side of the cube. One month is marked on the uppermost portion of a side of the cube and the other month is marked on the sides lowermost portion. The day marked cube has a different day of the week marked on five of the sides of the cube and the remaining two days of the week marked on the sixth side of the cube in the same manner as each side of the month marked cube. The date information is marked on two cubes which have numerical indicia marked on their sides.

The holder serves the dual purpose of supporting the cubes so that the day, month and date information are readily visible to an observer and also of appropriately masking the month marked cube and the day marked cube so that only a single month and single day are indicated on the outwardly facing side of the calendar.

The masking of the extraneous month and day is accomplished by a lip which extends upwardly from the base of the holder and covers the lowermost portions of the month marked cube and the day marked cube. Since the months are marked on the uppermost and lowermost portions of each side of the cube, the lip masks the month marked on the lower portion of the cubes side. Although the lip is not needed to mask the five, singly marked sides of the day marked cube, it is necessary to mask the sixth, doubly marked side of the cube. This is accomplished in the same manner as with the month marked cube.

These and other objects of this invention will be more readily understood and appreciated by reference to the following descriptions and drawings of which:

FIG. 1 is a perspective view of the cube calendar of this invention illustrating the day, month and date as Saturday, November 7;

FIG. 2 is a perspective of three sides of the month marked calendar cube;

FIG. 3 is a perspective view of the remaining three sides of the month marked calendar cube not illustrated in FIG. 2;

FIG. 4 is a perspective view of three sides of the day marked calendar cube;

FIG. 5 is a perspective view of the three remaining sides of the day marked calendar cube not illustrated in FIG. 4; and

FIG. 6 is a cross-sectional view of the cube calendar illustrated in FIG. 1 taken along the line 66.

Referring now to FIG. 1, a calendar 10 which includes four

cubes

12, 14, 16 and 18 supported in a holder 20 is illustrated. The calendar 10 indicates the month by the marking on the outwardly facing side of cube 12; the date by the markings on the outwardly facing sides of

cubes

14 and 16, and the day by the marking on the outwardly facing side of cube 18.

Referring now to FIGS. 2 and 3, the month marked cube 12 is illustrated. Two of the 12 months of the year are marked on each side of the calendar cube 12 so that all the months of the year are marked on the six sides of the cube. Although in FIGS. 2 and 3, selected pairs of months are illustrated for each of the six sides of the cube, no particular pairing of months for a side of the cube is important to this invention. Accordingly, months July and March are marked on side A of the cube, August and April on side B, September and October on side C, May and January on side D, December and November on side E, and June and February on side F. It is important, however, that the months be marked on the uppermost and lowennost portions of each side of the cube (as illustrated in FIGS. 2 and 3, uppermost and lowermost are relative terms depending on the orientation of the cube) so that the extraneous month is masked by the holder 20, as described in more detail below. Furthermore, the months are so marked on each side of the cube that the uppermost marked month (August on side B of FIG. 2) is inscribed right side up and the lowermost marked month (April on side B of FIG. 2) is inscribed upside down. Of course, if the cube illustrated in FIG. 2 is turned upside down so that side A forms the bottom side of cube 12, then, April will be the uppermost marked month and inscribed right side up and August will be the lowermost marked month and inscribed upside down. Accordingly, to illustrate a particular month on the cube calendar, the side of the cube with the month inscirbed on it is first selected and positioned in the holder 20 so that it is facing outwardly; then, the cube is adjusted so that the particular month selected is positioned on the uppermost portion of the cubes side.

Referring now to FIGS. 4 and 5, the day marked cube 18 is illustrated. On each of five sides of the cube, a day of the week is singly marked so that Wednesday is marked on side A, Tuesday is marked on side B, Monday is marked on side D, Friday is marked on side E, and Thursday is marked on side F. On the sixth remaining side of the cube 18, side C, both Saturday and Sunday are marked. As with the month marked cube 12, the Saturday and Sunday markings are inscribed on the uppermost and lowermost portions of side C so that the uppermost marked day (Saturday on side C of FIG. 4) is right side up and the lowermost marked day (Sunday in FIG. 4) is upside down. The selection of the days to be placed on the singly marked sides of the cube 18 and those to be placed on the doubly marked side C of the cube is, of course, not essential to this invention.

To illustrate a particular day of the week on the cube calendar 10, the side of the cube with the day inscribed on it is first selected and then positioned in the holder 20 so that it is facing outwardly; then, if necessary, the cube is adjusted so that the particular month selected is positioned on the uppermost portion of the cubes side.

Referring to FIGS. 1 and 6, the holder 20 is substantially L- shaped with a base member 28 and a rear member 30. The bottom side of each of the four cubes l2, l4, l6 and I8 is supported on the base member 28 which is downwardly inclined from the front to the rear of the holder so that the outwardly facing sides of each of the cubes is clearly visible to an observer. The holders rear member 30 prevents the cubes from slipping backwardly in the holder due to the inclined base member. A lip 22 extends upwardly from the front portion of the holder 20 in front of month marked cube 12 and day marked cube 18 in order to mask the lowermost portions of the outwardly facing sides of the cubes which are each positioned at an end of the holder in this embodiment. By masking the extraneous month (December in FIG. 1) marked in the lowermost portion of the cube 12, and the extraneous day (Sunday in FIG. 1) marked in the lowermost portion of cube 18, a single month and day are indicated on the outwardly facing sides of the calendar cubes.

The date marked cubes l4 and 16 have numerical indicia inscribed on their sides which enable their outwardly facing sides together illustrate any number from 1 to 31 corresponding to a particular date of the month, Since there is only one numeral marked on each side of the cubes, there is no extraneous matter to mask on the outwardly facing sides of the cubes. Accordingly, in this embodiment, the holder lip 22 only extends upwardly in front of the month marked cube l2 and the day marked cube 18. However, the holder 20 could be made so that the upwardly extending lip 22 extends horizontally the width of holder 20. In that case, the month marked cube and the day marked cube need not be positioned at the end extremities of the holder 20.

While the preferred embodiment of various aspects of the invention have been shown in the drawings, it is to be understood that this disclosure is for the purpose of illustration only in that various changes in shape, proportion, and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, as for example, the addition of cubesfor indicating the year, may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
