8 Claims.

. The present invention relatesto calendars or the like and it relates more particularly to diarycalendars of the type which indicate the date and also provide space for memoranda, etc.

Anobject of the present invention is to provide'a new and improved construction for a calendar or the like. Another object of the present invention is to provide an inexpensive and efficient diary-calendar which is simple to use. Still another object of the present invention is to provide a diary-calendar constructed and arranged for greater legibility while, at the same time, providing adequate diary space for the notation of memoranda or the like.

Other objects and advantages of the present invention are apparent from the following detailed description, appended claims and accompanying drawings.

It has been suggested in the past to provide calendars which show, simultaneously, the current month as well as the past month and the coming month. It has also been suggested in the past to provide a calendar wherein the dates of the month are printed in squares suficiently large to permit notation of memoranda to form a diary or record of past and future engagements or the like.

The present invention comprehends an im-' proved wall-mounted diary-calendar construction which has not, to my knowledge, been heretofore used or suggested and which provides greaterlegibility and diary-space for the present month, as well as simultaneously visible large-size and legible calendars covering the preceding month and the coming month, and which is constructed and arranged to permit quick and easy change from one month to the next with means for retaining used month-pages in firmly-secured out-of-the-way position while permitting reference thereto without the need for removing the diary-calendar from its wallmounting.

Generally speaking, the present invention contemplates a diary-calendar or engagement-calendar which can be sold in closed form generally resembling-a book having front and back covers of cardboard or the like mounted on a hingemember, and whichcan be mounted on a wall with the free edge of thefront cover member uppermost and with an integrally-formed depending fiange or flap portion at said upper edge within which are mounted one or more concealed spring clamps tending to maintain the flange or flap in closed position so as to provide a resilient frictional engaging surface into i which the edges of individual calendar-pages can be tucked (after the months have passed) to maintain them in firmly-secured out-of-theway position while permitting them to be folded back for reference if necessary. The individual month-sheets which are hingeably-connected intermediate the front and back covers are arranged so that the calendar for the current month appears as the low-er page (the weeks of the month being arranged in horizontal lines, in conventional manner) with the individual days imprinted within squares or the like providing space for memoranda, and so that the preceding and following months appear in smaller size on the simultaneously visible upper page.

For the purpose of illustrating the invention, there are shown in the accompanying drawings forms thereof which are at present preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangements and organizations of the instrumentalities as herein shown and described.

Referring to the accompanying drawings in which like reference characters indicate like parts throughout:

Figure .1 represents a perspective view of one embodiment of the present invention shown in closed position, as it would be sold or stored.

Figure 2 represents an elevational view, showing the appearance of the calendar when opened to the first month.

Figure 3 represents a perspective view," on a somewhat reduced scale, showing the appearance of the calendar when hung on the wall and when turned to the next month.

Figure 4 represents a cross-sectional view generally alongthe line 4-4 of Figure 3.

Figure 5 represents a perspective view, on an enlarged scale, of one of the spring-clamps using the'embodiment of Figures 1-4.

Figure 6 represents an elevational view of the front or top cover in unfolded position.

Figure '7 represents an elevational view of the rear or bottom cover in unfolded position.

In one embodiment of the present invention shown generally in Figures 1-3, I may provide a wall-calendar comprising a front or top cover 20,

.a rear or bottom cover 2| and a plurality of intervening pages pivotally mounted upon a hingemember-22.

The top cover 20 is of generally two-ply construction formed from a generally rectangular piece of cardboard, as indicated in Figure 6, by first bending along a central transverse fold line 23 and thereafter bending along fold lines 24 and 25, extending generally parallel to, and equidistant on either side of, the central fold line 23; aligned pairs of openings 26 and 2'! being first formed along the fold lines 24 and 25 to receive a cord 28 by which the calendar can be hung from a nail or the like; the cord being knotted intermediate the openings 21 along the fold line 25 and extending through the openings 26 and 2! to form a loop on the other side of the fold line As can be seen particularly in Figures 3 and 4, the panels 29 and 3|! extending intermediate the fold lines 24-23 and 2523 form a two-ply depending flange at the top of the top cover 26 separated from the inner and outer plies of the cover 2!] by the juxtaposed fold lines 24 and 25.

As indicated particularly in Figures 6, the free edges of the plies 3| and 32 are perforated as at 33 and 34 to provide a pivotal connection with the elongated hinge-member 22.

A pair of spring-clamps 35 are mountedso as to straddle the fold line 25 and thereby to press the panel 30 against the upper edge of the inner ply 3|. The spring-clamps may be made of thin flat ribbon steel or the like having legs extending substantially the entire transverse dimension of the panel 30. If desired, a pair of integrallyformed pointed upwardly-projecting lockingears 36 maybe struck out from adjacent the ends of each spring-clamp so as to" protrude'inwardly and partially to pierce the panel 30 and the upper portion of the inner ply 3| so as to prevent dislodgement of the spring-clamps.

However, the locking-ears 36 may be omitted, especially since, as shown particularly in Figures 3 and 4, the fold line 24 overlies the closed ends of the spring-clamps 3650 that the panel 29 and the outer ply '3'2 tend to prevent dislodgement of the clamps.

The function of the clamps in the calendar construction of the present invention will be more fully described hereinbelow.

The rear orbottom cover 2| is also of twoply construction including an inner-ply 37 and being provided with aligned perforations 40 and 4| to permit mounting on the'hinge-member 22.

Alsomounted on the hinge-member 22 intermediate the top and bottom covers 2|] and 2| are twelve cardboard sheets representing the months of the'year.

As shown in Figure 2, the first page or side of the first sheet may have the days of January arranged so that each week runs horizontally in the usual manner.

I prefer to arrange the individual days so that sufiicient space is provided adjacent each datenumber to permit the making of memorandaetc. to permit the calendar to be used as a diary or record of engagements orthe like. This can be done by providing horizontal and vertical'rulinglines 42 and. 43 so that each day has a square for the making of memoranda, with the date-member in one of the upper corners of the square. However, the ruling- lines 42 and 43 may be omitted, if desired.

Upon the inner-ply 3| of the top cover 20 there are imprinted calendar-representations of the preceding and following months, 44 and 45 respectively; that is, the month of December of the preceding year and the following February. These supplemental calendar- representations 44 and 45 are, of course, appreciably smaller in size 4 than the main calendar representation 46 for the month of January and are intended simply to provide ready reference in calculating periods extending beyond the current month.

I also prefer to imprint the month and year designation for the main calendar-representation 46 along the lower edge of the inner-ply 31, as at 41 (instead of at the top of the calendarpage itself) so as to provide more room on the calendar-page for the notation of memoranda, as mentioned above.

After the month of January has passed, the first calendar-page is adapted to be lifted up (pivoting on the hinge-member 22) so that its free edge (which in the upwardly-lifted position terminates about half-way intermediate the upper and lower edges of the downwardly-depending flange portion of the top cover 20) can be tucked underneath the flange portion intermediate the panel 30 and the upper edge of the inner-ply 3|. As can be seen particularly in Figure l, the upper edge is thus frictionally retained in tucked-in position by the springclamps 35.

As can be seen particularly in Figure 3, the reverse side of the first calendar-sheet, which is now visible above the hinge-member 22, contains supplemental calendar- representations 48 and 49 for the previous and coming months, namely the months of January and March. The lower edge of this reverse side also contains the currentmonth-and-year designation 50, namely February 1948. The front side of the next calendarsheet, which is now visible below the hinge-member 22, contains the main calendar-representation 5| for the month of February which is similar to the main calendar-representation 46, except, of course, for the variations in the days of the month.

From the foregoing it is apparent that, as each month passes, another calendar-sheet is flipped up and tucked underneath the flap-portion and is held in place by the spring-clamps 35, exposing successive current calendar-representations and F supplemental calendar-representations.

As indicated in' Figure 7, the inner-ply 31 of the bottom cover 2| may be imprinted with a calendar showing all twelve months of the year.

The reverse side of the last calendar-sheet may be provided with smaller-size yearly calendars (not shown) for the preceding and coming years so that, when the last calendar-sheet is lifted up, complete calendars covering a three-year period are visible simultaneously. This last fea- F ture is important in that it permits brief notations of appointments, dates, etc., far in ad- Vance. As indicated in Figure 1, the novel calendar construction of the present invention can be sold or transported or stored in compact closed book form, which can be quickly and easily opened and mounted on a wall and, thereafter, changed from month-to-month without taking the calendar down and without tearing off or otherwise destroying the month-sheets.

Thus, the novel calendar construction affords a permanent record of memoranda, engagements, etc. which can be easily referred to by simply pulling out the upper edges of the turned-up pages temporarily and thereafter re-inserting them).

The closed book form of the calendar takes up little space so that a large number of them can be conveniently stored away to enable records to be kept over a long number of years.

The simplified one-piece construction for the assemble so that it can-be sold at relatively low cost. I

Thepresent invention may be embodied in other specific forms without departing from the spirit -or essential attributes thereof, and it is therefore desired that the present embodiments be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having thus described my invention, I claim as new and desire to protect by Letters Patent:
