Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable calendar marker for indicating the date of each day, and more particularly to a movable calendar marker used in a hanging monthly calendar.

In our modern daily lives, we are surrounded by highly developed electrical devices, such as computers, which are used in every field, and everything functions precisely and efficiently.

Despite this, on the other hand, we are busy with various tasks such as daily work, grasping the general social situation, absorbing knowledge, increasingly complex interpersonal relationships, and dealing with the future, and we often find ourselves unable to do simple things. Sometimes I forget.

And the date is no exception, for example, although there are monthly calendars in each home, office, etc., and there are signs at train stations that generally indicate the current day, there are times when it is difficult to know the current day. There were times when I didn't know how many items were left in the month, and I had to change the date of my appointment or miss a business opportunity.

Therefore, with the intention of eliminating the above-mentioned inconvenience, we have developed a conventional movable ring made of a permanent magnet that slides on the surface of the calendar, and a movable ring made of a permanent magnet that slides on the surface of the calendar as the movable ring slides. A date display for a calendar consisting of a driven ring has been proposed (note:
According to Publication No.-27750.

) In such a ring-shaped permanent magnet, it takes time to cut out the mold, and it is difficult to magnetize it well, but it is also difficult to make it strong, so the permanent magnet itself is expensive and has a short service life. Also, since it is ring-shaped, the Gauss is smaller than that of a ring with the same outer diameter, and therefore the adsorption force is also weak.

This invention was developed in order to eliminate the inconvenience of tilting, and its purpose is to form a recess on the upper edge of the frame having the display window and on the back surface of the upper protrusion, and to create a recess inside the recess. By fitting a permanent magnet and fixing it with adhesive to form a marker body, the corresponding date can be displayed accurately through the display window, and a large It is an object of the present invention to provide a movable calendar marker which can form a concave part for a permanent magnet, and can therefore be made large so as to enable the use of a large Gaussian permanent magnet, and at the same time can firmly hold it, and for other purposes. The object of the present invention is to provide a movable calendar marker that can provide rigidity to the upper edge of the marker body due to the presence of a recessed portion.

Another object of the present invention is to use the permanent magnet of one marker body and a driven permanent magnet of the same size, thereby increasing the attraction force between both permanent magnets, and By forming the part in an arc shape, it is possible to operate smoothly without the corner part catching on the back side of the current month's calendar and the front side of the next month's calendar during transition, as in the case where the peripheral edge is formed in a right angle shape. Provides movable calendar markers.

Another object of the present invention is to provide a movable calendar marker that facilitates the configuration and magnetization of the permanent magnet itself, thereby reducing costs accordingly.

Next, we will explain one embodiment of the present invention that can achieve the above object.
3 and 6 and 7 will be explained in detail.

In these drawings, a indicates the main body of the marker, which may be a thin synthetic resin board (for example, a vinyl chloride board with a thickness of about 0.3 to 1+U+) or a relatively thick paper (for example, 0.5 to 1
rrtrn).

That is, as shown in FIGS. 1 to 3, it consists of a central display window 1 and a frame 2 having an upward protrusion 2a1, and a recess 2a2 is formed on the back surface extending from the upper edge 2a to the protrusion 2aIK. ing.

Reference numeral 3 indicates a permanent magnet magnetized to thin ferrite, synthetic resin containing iron powder, rubber containing iron powder, etc., and the permanent magnet 3 is fitted into the recessed portion 2a2 described above and is fixed with an adhesive.

b indicates a hanging monthly calendar, with "1 to 30" and "1 to 31" representing the "day" as in the conventionally well-known calendar.
The number 4, the letter 5 representing the day of the week, etc. are printed on it.

6 indicates a driven permanent magnet. As shown in FIGS. 6 and 7, it is formed into a flat disk shape, and the peripheral edge 6a is formed in an arc shape, so that when the peripheral edge 6a moves diagonally upward, downward, horizontally, horizontally, etc. It is designed to prevent the back side of the marker from coming into contact with the surface of the next month's item, or to reduce the frictional resistance in the case of contact, so that the marker body a can be transferred smoothly. It is made by magnetizing the same material as the magnet 3.

In the diagonal configuration, if the back surface of the permanent magnet 3 is set to the N pole, the surface of the driven permanent magnet 60 is set to the S pole, and the marker body a is positioned at the number 4 indicating the current day (Note, Fig. 1). The number 4 appears through the display window 1 as shown in the figure.

) Also, on the back side of the monthly calendar b, by adhering the driven permanent magnet 6 to the location where the permanent magnet 3 is located via the monthly calendar b, the marker body a is placed above the corresponding opening of the suspended monthly calendar b. is maintained.

Next, when changing the date, move the marker body a along the surface of the monthly calendar b (note, keep it in sliding contact as much as possible).

) to move. In such a case, the driven permanent magnet 6 moves to a state where it is attracted to the permanent magnet 3 via the monthly calendar b, and the corresponding day is thereby changed and displayed.

One embodiment of the present invention has been described above, and the protrusion 2a1 on the upper edge 2a of the marker main body a may be protruded in an angular shape as shown in FIG. 4, or in a semicircular shape as shown in FIG. Also, the outer periphery of the driven permanent magnet 6 is coated with plastic or paint to form a smooth coating 7, which makes it more attractive than the one shown in FIGS. 6 and 7.
Furthermore, an attempt may be made to further reduce the frictional resistance.

As described above, the present invention forms a concave part on the upper edge of the frame having the display window and the back surface of the upper protruding part, and fits into the concave part with a permanent magnet and is fixed with an adhesive. By configuring the marker body, the corresponding date can be displayed accurately through the display window, and a large recess for a permanent magnet can be formed on the upper edge and the back surface of the upper protrusion. The large size makes it possible to use a permanent magnet with a large Gaussian force, and at the same time it is possible to firmly hold this magnet.The presence of the recessed part also makes it possible to impart rigidity to the upper edge of the marker body. By being able to use one permanent magnet and a driven permanent magnet of equal size, and by increasing the attraction force between both permanent magnets, and by forming the peripheral edge of the driven permanent magnet into an arc shape, The peripheral edge is formed at a right angle, so that it can operate smoothly without the corner getting caught between the back side of the current month's calendar and the front side of the next month's calendar, and also because of the shape and configuration of the permanent magnet itself. This has the effect of making magnetization easier and resulting in a correspondingly lower cost.
