Claims. (Cl. 40-110) This invention relates to calendars, and more particularly to a device to be used in conjunction with wall calendars to focus a persons attention upon a particular date indicia on wall calendars. It is a principal object of this invention to provide a focus device to be used on wall calendars to immediately focus the attention of the calendar user on a particular dateindicia on the calendar. It is a further object-of this invention to provide such a focus device which will support itself in simple manner upon the calendar and which may be moved easily from date to date on the wall calendar.
It is a further object of this invention to provide such a calendar focus device for wall calendars which is very simple to manufacture and very foolproof to use.
It is a further object of this invention to provide such a focus device for wall calendars which will be intriguing to the user of the calendar and which may carry advertising indicia, whereby the, user of the wall calendar will be induced to display the advertising indicia on his calendar.
Other objects and advantages of the present invention will become apparent from the following description read in conjunction with the attached drawings in which:
FIG. 1 is a face view in elevation of a wall calendar on which the calendar focus device of my invention is mounted;
FIG. 2 is a vertical sectional view of the device of FIG. 1 taken along the plane indicated at 22 in FIG. 1;
FIG. 3 is a back view of the device of FIG. 1 and FIG. 2 taken in the direction indicated at 3-3 in FIG. 2, and
FIG. 4 is a vertical cross-sectional view similar to FIG. 2 but illustrating an alternative form of my invention.
Referring now in detail to the drawings, a wall calendar 10 comprising a plurality of calendar pages 12 are bound together by suitable means and provided with an aperture 14 in the top thereof by which the calendar may be hung on the wall of a room. The calendar carries customary indicia of the day of the month with the indicia for all of the days of one month arranged on one page.
Mounted on the calendar as illustrated in FIG. 1 is a calendar focus or marking device 16 encircling a date indicia on the calendar which is to be called to the attention of persons using the calendar. Conveniently, the focus device 16 is moved from date to date on the calendar to always focus the users attention on the current date.
The calendar focus device 16, as illustrated in greater detail in FIGS. 2-3, comprises a focus or marker member 18 which is conveniently made of a light weight material such as wood or plastic and which is provided with a central aperture 20 therein through which one date indicia on the calendar may be viewed. A pair of magnets 22 and 24 are mounted in the focus member adjacent to the face of the top page of the calendar, and a second pair of magnets 26 and 28 are mounted on the back of the calendar page in alignment with magnets 22 and 24, respectively. The north poles of magnets 22, 24, 26 and 28 are in alignment with the south poles of magnets 26, 28, 22 and 24, respectively. The magnets 26 and 28 are connected together by a suitable connecting strip 30 which is conveniently a small strip of thermo-plastic material in which the magnets 26 and 28 are embedded.
A small plaque 32 is embedded in the face of focus member 18 remote from calendar page 12, and plaque 32 may carry any desirable advertising indicia. Alternatively the plaque may be made of a material on which the calendar user may write suitable reminders and which would permit erasure of the reminders when the date referred to thereby has passed.
The wall calendar focus device of this invention is attached to a wall calendar, as illustrated in FIGS. 1 and 2, and circling the current date of the month or any other date of the month to which the calendar users attention is to be directed. The device is sufficiently light weight and the strength of magnets 22, 24, 26 and 28 is sufliciently strong that the device will support itself in position on the calendar. Because of the fact that each of the magnets is cooperating with a second magnet in holding the focus device in place, the focus device can be moved from date to date along the face of the calendar by merely grasping the focus member 18 and sliding it along the face of the calendar, the attraction between magnets 22 and 26 and magnets 24 and 28 causing the magnets 26 and 28 together with their connecting strip 30 to track focus member 18 as the latter is moved. Because of this feature of the focus device of this invention, the two pairs of magnets need be aligned with each other only once a month, and thereafter successive days of the month may be accented by merely moving the focus member 18 on the face of the calendar.
When the two pairs of magnets, magnets 22 and 24 and magnets 26 and 28, are first aligned with each other at the early part of the month, it isdesirable that simple fool-proof alignment be provided in order to prevent separation of the two pairs of magnets subsequently in the month and in order to prevent the necessity of experimentation in bringing the two pairs of magnets into alignment. For this reason the magnets of each pair are oriented in accordance with the orientation of magnets 26 and 28 illustrated in FIG. 3 in which the four poles of the two magnets lie generally on a circle with the north and south poles alternating around circle. With the magnets oriented in this manner, and with the proper face of connecting strip 30 presented to the back of the calendar page, connecting strip 30 may be rotated indiscriminately, and when focus member 18 is brought adjacent to connecting strip 30, focus member 18 and connecting strip 30 will snap into alignment.
In order to facilitate sliding of the calendar focus device of this invention along the page of a calendar it is desirable that the connecting strip 30 and magnets 26 and 28 cause as little friction as possible with adjacent pages of the calendar. For this reason, the calendar focus device of this invention is preferably provided with the connecting strip 34 illustrated in FIG. 4 in which the side of connecting strip 34 remote from the calendar page to which the device is attached is provided with smoothly rounded edges enclosing the magnets 26 and 28.
