MOUNTING FOR CALENDAR PADS Filed Aug. 17, 1956 IN V EN TOR.

United States Patent MOUNTING FOR CALENDARPADS Henry Ray, New York, N. Y., assignor to Ever Ready Calendar Manufacturing Co., Jersey City, N. L, a corporation of New Jersey Application August 17, 1956, Serial No. 604,799

Claims. (Cl. 40-120) This invention relates to an improved mounting for a conventional desk calendar of the type which includes asupporting base, a pad of independent leaves or pages for each day of the year and a frame adapted to support the pad to permit the front leaves tobe successively removed or turned back to displaythe faces ofthe following leaf and expose successive leaves, and a base upon which the frame is mounted.

While relatively small calendars of the above-described type are commonplace, a principal problem which has arisen in their construction is the provision of a mounting which will allow the leaves bearing indiciaof the days of the year which have just passed to be removed and leaves bearing indicia of the days of the coming year to be inserted rapidly and easily in their place.

Consequently, it is a principal object of the present invention to provide a mounting for calendar pads which will permit quick and easy removal and replacement of the calendar pads.

it is another object of the present invention to provide for a mounting for calendar pads in which a frame for exposing successive leaves is releasably anchored to the base of the calendar.

It is still another object of the present invention to provide for a mounting for calendar pads in which a variable position member attached to the frame supporting the pad will firmly anchor the frame to the calendar base in locked position and free the frame from the base in released position.

A further object of the invention is to provide an arched leaf supporting frame having plural upwardly extending arches and having a novel blade spring of substantially U-shape which locks the frames on the base and which permits release thereof when the opposed legs of the spring .are flexed toward each other.

Yet another object of the invention is to provide a rotary type clamping means for securing the arched frame to the base.

These and other objects and features of advantage of the present invention will become more apparent when taken in connection with the illustration of the invention in the accompanying drawing, inwhich:

Fig. l is a perspective view of a conventional desk calendar provided with .an arched leaf-supporting device embodying the present invention.

Fig. 2 is an enlarged perspective view of the invention.

Fig. 3 is an enlarged vertical section on line 3--3 of Fig. 1.

Fig. 4 is a broken vertical section showing a modification of the invention, the section being taken on line 4--4 of Fig. 6.

Fig. 5 is a top plan view thereof and showing the parts of Fig. 4 in secured position.

Fig. 6 is similar to Fig. 5 but shows the parts in released position.

Referring now to the drawing, the calendar base 1 has a generally circular aperture 2 with two aligned slots 5 extending diametrically from the aperture 2 and which are I 2,835,058 Fate-rated May 20, 8

just wide enough to accommodate the diameter of an arched frame 6 in snug-fit relation, as shown in Figs. 1 and 2. The frame may be made from wire and includes two spaced arch-shaped loops 7 connected by a horizontal portion or loop 4. The base 1 is formed with two cylindrical sockets 20, which receive, respectively, the two free ends 3 of the transfer arches 7. The calendar pad 21 is shown in dotted lines on the far side of the base 1 in Fig. l.

The horizontal portion or loop of the wire frame 6 carries a blade spring 10, which is essentially a U-shaped latching element. The rounded bottom of the U is shaped to fit tightly around portion 4- of the frame 6. Each of the sides of the lJ-shaped spring has at its top edge an upwardly extending center portion 13 flanked by two lower shoulders 14. The interconnecting loop 4 has several projections, including two projections 11, symmetrically disposed on the bottom which serve to centrally locate the blade spring it Another projection 12 in the center of the loop 4 prevents the blade spring 10 from rotating around the bottom of the loop.

Fig. 3 shows the parts in assembled relation. The frame is positioned in the radial slots 5 and the four shoulders 14 engage the underside of the base wall at the areas indicated at 19. Each of the underside areas 19 carries a boss 15 which assists in confining the blade spring 1% when the device of the invention is in locked Position. In locked position the ends 8 of the transfer arches 7 are inserted completely Within the cylindrical sockets 26 Also in locked position the wire frame is safely anchored in the base 1, upward movement being resisted by the shoulders 14 of the blade spring 10 abutting against the underside areas 19 of the base 1. Downward travel of the frame is limited by two projections or stops 9 on the vertical legs of the frame which contact the top surface of the base 1 when the frame is in the position shown in Fig. 1. Furthermore, the bottoms of the sockets 20 serve as stops for the ends 8 located therein. The depth of the sockets 20 is correlated with the location of the projections 9 on the frame 6 in order to ensure a perfectly perpendicular position of the wire frame with respect to the top of the base 1.

To assemble the calendar containing the present in.- vention the spring-10 is compressed at the center portions 13 of the sides of the spring. When the frame is stopped in its downward travel due to the projetcions 9 and the bottoms of the socket 20, as described above, the blade spring 3th is released and the frame is locked in position.

In order to remove the wire frame from the base 1 the extending center portions 13 of the spring 10 are pressed together until they reach the position shown by the dotted lines in Fig. 3. This compression disengages the shoulders 14 from the underside areas 19, and the entire frame can now be lifted from the aperture 2 and the slots 5 and the sockets 20.

Amodification of the invention is illustrated in Figs. 4, Sand 6. Instead of the blade spring 18 described above, this modification has a rotary latch 16 shaped like a fiat hub with radially extending spokes and the latch is pivot ally secured at 22 to the loop portion 4'. This portion instead of being horizontal throughout its length is upwardly ofiset at its center and the latter is flattened as shown at 23. The latch 16 has, radially disposed, two types of diametrically opposed arms. Two opposed arms 17 comprising one pair of arms are long and flat and disposed in the horizontal plane with the latch 16. These locking arms 17 have a width slightly less than that of the slots 5'. The remaining arms are supporting arms 13. They are bent upwardly and then horizontally so that the distance between the upper surface of the latch 16 and the underside of the horizontally bent portions of the 3 supporting arms 18 is very little larger than the thickness of the top of the calendar base 1.

To insert the frame 6' into the aperture 2 and the slots 5, the latch 16 must be rotated until the locking arms 17 are parallel with the loop 4', as in Figs. 4 and 6. Then the loop 4' is inserted into the base 1', the downward travel stopping when the supporting arms 18 contact the top of the base 1. In this position the latch 16 is rotated approximately 90 until it reaches the position shown in Fig. 5, so that the frame 6 will be locked in place. Such locking is firm and effective, as the locking arms 17 of the latch 16 are under the top of the base 1, the supporting arms 18 are above the top of the base 1', and the vertical distance between the locking arms 17 and the supporting arms 18 is only slightly greater than the thickness of the top of the base 1'.

For removal, the latch 16 is rotated to the position of Fig. 6. In this modification there is no need for the projections 9 on the vertical arms of frame 6 as the supporting arms 18 function as stops.

It will be apparent that alterations, modifications and substitutions may be made in the illustrations of the invention described above without departing from the spirit I ing a pair of inverted U-shaped arches and a generally horizontal loop connecting said arches, the base having a plurality of vertical openings into which the frame is downwardly moved to rigidly support the same in leafsupporting position, two of said openings forming sockets to receive the free ends of the arches, another opening having narrow, opposed, radially extending slots which receive the loop ends of the arches, said spring being of substantially U shape with two upwardly extending legs and being carried by the loop for securing the frame on the base and extending upwardly from the loop through said last opening and having shoulders which underlie the base to prevent upward movement of the frame until the two legs of the U-shaped spring are moved together to free the shoulders, and a stop limiting downward travel of the frame in the supporting openings.
