Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a perpetual calendar that displays a calendar for a specific month by correspondingly shifting each day of a month and a day of the week.
[0002]
[Prior art]
Conventionally, as a circular perennial calendar, for example, there is one shown in Patent Document 1. This perennial calendar uses a circular day of the week and a date board having a smaller diameter so as to be rotatable, and uses the date and day of the week together. The date and day of the week are arranged in a circle.
[0003]
In addition, the perpetual calendar disclosed in Patent Document 2 is provided with a rotatable date display panel having a rectangular year / month display column in which dates are arranged in a rectangular shape with a plurality of lines arranged every week, and a circular day-of-week search panel. It is a thing. In the gap between the year / month display field and the day of the week display field, a connection line is written so that the date corresponds to the day of the week.
[0004]
When using a perpetual calendar, the date of the month and the day of the week are combined to correspond to the other date and day of the week. Then, look at the date of the day you want to know the day of the week and follow the connection line to confirm the corresponding day of the week.
[0005]
[Patent Document 1]

[Patent Document 2]
Utility Model Registration No. 3071172 (page 2-9, Fig. 1)
[0006]
[Problems to be solved by the invention]
However, since the perpetual calendar of Patent Document 1 arranges dates in a circle, in order to improve visibility, the diameter of the circle has to be increased, and the main body becomes larger and the usability becomes worse. There's a problem.
[0007]
In addition, in the perpetual calendar of Patent Document 2, the gap between the year / month display column and the day of the week display column is connected by a connecting line, but the distance of the day of the week and the date is far away, so the movement distance of the line of sight is There is a problem that it takes time to check the day of the week.
[0008]
Therefore, the problem to be solved by the present invention is to provide a perpetual calendar that can form a main body compactly and can quickly check the day of the week.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, a centennial calendar according to the present invention has a day display window that is formed in an arc shape and displays each day of the week, and a date display section that is disposed below the day display window. A perpetual calendar provided with a plate and a day-of-the-week display plate arranged on the back side of the date display plate so as to be rotatable on the date display plate and in which the days of the week are listed in the circumferential direction in a position overlapping the day-of-week display window Each date of the date display section is divided into a plurality of lines every week, and each line is arranged in an arc along the day display window.
[0010]
The day of the week display board and the date display board can be formed using, for example, paper, wood, plastic, metal, ceramics, or a laminate of these.
[0011]
The day of the week display plate is preferably formed in a circular shape, but may be formed in another shape such as a rectangle or a triangle. The day of the week can be described in Japanese in the order of “Sun”, “Month”, “Tue”, “Wed”, “Thurs”, “Fri” and “Sat”, and “Monday”. English and other foreign languages can be used, and may be described by abbreviations such as “Mo” and “Mon”. Further, the color is arbitrary, and it is possible to color Sundays red or Saturdays blue.
[0012]
The external shape of the date display board is arbitrary, and can be formed in, for example, a rectangle or a circle. The date display unit may print the date on a date display board, or may attach a label on which the date is printed. It is also possible to print the date on a magnetic sheet or a sheet having a weak adhesive force and stick this on a date display board.
[0013]
In order to rotatably provide the day of the week display plate on the date display plate, it can be fixed using, for example, a bearing or an eyelet. It is also possible to have a structure that holds the outer periphery of the day display plate.
[0014]
Since each row of the date display section is arranged in an arc along the day display window, the gap between the date display section and the day display window is reduced, and the line-of-sight movement distance when the day of the week and the date are matched is reduced. Get smaller.
[0015]
By arranging the dates of the date display section in a plurality of columns for each day of the week and arranging the characters in the same direction and arranging the columns in a straight line and in parallel, the correspondence between the date and the day of the week can be clarified. The direction of the character means a vertical direction or a horizontal direction which is a reference when writing the character.
[0016]
Since the day of the week display board rotates, the vertical direction is not fixed. Therefore, in order to reduce the maximum inclination angle of the day of the week visible in the day of the week display window, it is preferable to match the vertical direction of the character for displaying the day of the week with the radial direction of the day of the week display board.
On the other hand, since the character displaying the date does not rotate, the direction can be determined in advance. Each line of the date display section is arranged in an arc, but each character that displays the date does not need to be tilted according to the character that displays the day of the week. The direction can be determined.
[0017]
When the radius of each line arranged in the arc shape of the date display portion is set to the same radius as that of the day of the week display window, the interval between the characters in the vertical direction of each line and the arrangement position with respect to the adjacent characters are constant.
[0018]
When the date display board is a white board and the day of the week display window is provided with a transparent plate in a through-hole formed in the white board, characters can be written in the margin of the perpetual calendar and the day of the week display. The board can be prevented from being stained.
[0019]
The white board refers to a board on which the erasable characters can be written, for example, a board surface provided with a hollow enamel white or a baked steel white. Enamel white is obtained by baking enamel glassy material on the surface of the substrate at a temperature of about 500 ° C. to 800 ° C. Steel white is obtained by applying a white paint for blackboard to the substrate and baking at 200 to 300 ° C. Say things.
[0020]
Characters can be written on the surface of the white board with a marker using an alcohol or ketone paint, and can be easily erased by wiping with an eraser. A magnet such as a magnet sheet can be detachably attached to the surface of the whiteboard.
[0021]
The transparent plate provided in the display window is preferably formed of a material that can write characters with a marker and can be wiped off with an eraser. This transparent plate may be provided on the surface of the day display plate, or may be provided on the back surface of the date display plate, or may be fixed by being sandwiched between the day display plate and the date display plate. By providing the transparent plate, the sliding resistance during rotation of the day display plate can be reduced.
[0022]
An arc-shaped day adjustment window is formed at the bottom of the date display section, and a year display section is provided along the day adjustment window. A label that can be replaced is provided on the year display section. When the day adjustment month is displayed on the plate along the day adjustment window, the day of the week is adjusted by rotating the day display plate so that the day adjustment month corresponds to the preset year. be able to.
[0023]
Since the frequency of updating the year display is low, it is overwritten using a label. By changing the label, the perpetual calendar can be used until the product is damaged. Moreover, a year display part can be formed small by using a label.
[0024]
If a protrusion is formed on the back surface of the day of the week display plate, it can be used as a handle for rotating the day of the week display plate, and the rotation operation can be performed with a small force.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
(First embodiment)
FIG. 1 is a front view of a perpetual calendar according to the first embodiment of the present invention, and FIG. 2 is a side view of the perpetual calendar. As shown in FIGS. 1 and 2, the perpetual calendar 1 of the present invention includes a date display board 2 provided on the front side, a day of the week display board 3 provided rotatably on the back side of the date display board 2, and a date. And a transparent plate 4 attached to the back surface of the display plate 2. In the present embodiment, the upper, lower, left, and right directions when the fountain calendar is viewed from the front will be described as the upper side, the lower side, the left side, and the right side, respectively.
[0026]
The date display board 2 has a day-of-week display window 5 that is formed in an upwardly protruding arc shape and displays each day of the week, and a date display section 6 disposed below the day-of-week display window 5. Yes.
[0027]
The day of the week display window 5 is constituted by a through hole formed in the date display plate 2 and the transparent plate 4. The day-of-week display window 5 is disposed within a range of a central angle of 90 ° with respect to the rotation center of the day-of-week display plate 3 and has a constant radial width.
[0028]
Each date of the date display unit 6 is arranged in five lines every week, that is, every seven days, and each line is arranged in an arc along the day display window 5. The radius of the arc-shaped center line connecting the centers of the characters of each line is set to the same size as the lower frame line of the day of the week display window 5.
[0029]
Each date on the date display unit 6 is arranged in seven columns for each day of the week and arranged in the same direction of characters. For example, in the leftmost column, dates “1”, “8”, “15”, “22”, and “29” are arranged. The direction of the characters is such that the vertical direction of the characters is the same as the vertical direction of the date display board 2. Each row is arranged in a straight line up and down, and arranged in parallel. Each character is the same size.
[0030]
An arc-shaped day adjustment window 7 is formed below the date display unit 6. The day-of-week adjusting window 7 is disposed within a range of a central angle of 90 ° with respect to the rotation center of the day-of-week display plate 3 and has a constant radial width. Further, it is arranged closer to the center of rotation of the day display plate 3 than the day display window 5.
[0031]
Below the day of the week adjustment window 7, a year display unit 15 is provided in an arc shape along the day of the week adjustment window 7. This year display unit 15 is provided with labels 8 to 14 that can be pasted. The number written on each label 8 to 14 represents the year, “21” for label 8, “16” for label 9, “17” for label 10, “18” for label 11, and “12”. Is “19”, the label 13 is “25”, and the label 14 is “15”. For example, after the end of 2003, the label 14 is peeled off, and another label described as “20” is attached. The number of the label representing the leap year is written in red. For example, the number “16” in the label 9 is in red.
[0032]
The label for replacement is stored in another place together with a table indicating the replacement position, but it can be configured to be provided in the margin on the back side of the date display board 2 and the day of the week display board 3. .
[0033]
FIG. 3 is a front view of the day of the week display board. As shown in FIG. 3, the day of the week display board 3 is formed in a circle and displays each day of the week on the outermost peripheral part of the display area equally divided by a predetermined angle with respect to the center position, and the day of the week is displayed inside it. The month for adjustment is displayed. Each day of the week is arranged at a position overlapping the day of the week display window 3 and is described in order in the circumferential direction. Each month is arranged at a position overlapping the day adjustment window 7.
[0034]
The day of the week is displayed in Japanese and English abbreviations. For example, on Sunday, “Sun” is displayed at the top and “SUN” is displayed at the bottom. In addition, Monday through Saturday are displayed in black, but Sunday is displayed in red.
[0035]
The numbers “1” to “12” are displayed on the month. The numbers “1” and “2” are black and red, and the numbers “3” to “12” are numbers. It is written in black only. The red numbers surrounded by the two-dot chain line in FIG. 3 are used when displaying the calendar for January and February of the leap year.
[0036]
As shown in FIGS. 1 and 2, the date display board 2 and the day of the week display board 3 are rotatably connected by eyelets 16. A support member such as a bearing can be used instead of the eyelet 16.
[0037]
A cap member 17 having the same color as the date display plate 2 is provided at the front end of the eyelet 16. The cap member 17 can be, for example, a seal attached to the eyelet 16.
[0038]
A bar-shaped protrusion 18 extending in the radial direction is formed on the back surface of the day of the week display board 3. The protrusions 18 are provided at two places every 180 °, but can be provided at three or more places. By forming the protrusion 18 in a bar shape, the number of places that can be pinched with a finger increases, and the day of the week display board 3 can be easily rotated.
[0039]
Next, the display state of the perpetual calendar will be described. The number of days in each month excluding February is up to 30th or 31st. Since the remainder when dividing this by 7 is 2 or 3, the day of the week is shifted by 2 or 3. In February, the average year is 28 days and the leap year is 29 days. Therefore, in normal years, the day of the week is the same in February and March, and in the leap year, the day of the week is shifted by one.
[0040]
As shown in FIG. 3, the numbers indicating each month are arranged according to this rule. For example, since there are 31 days in January, the black number “2” of the year display unit 15 is arranged at a position shifted three times clockwise from the black number “1”. Further, the red number “2” is also arranged at a position shifted by three clockwise from the red number “1”.
[0041]
The black number “3” is arranged at a position shifted seven times clockwise from the black number “2”. This represents the same day of the week. Further, the black number “3” is arranged at a position that is shifted eight times clockwise from the red number “2”. This represents the same day of the week as one day off.
[0042]
The numbers “4” to “12” are all black, and there are 2 or 3 shifts in the day of the week in both normal and leap years, so the interval between each number is 2 or 3 (or a multiple of 7 plus this) )
[0043]
A leap year is a year in which the year is divisible by four. As an exception, a year divisible by 100 is not a leap year, except for a year divisible by 400. For example, the year 1900 is a normal year, the year 2000 is a leap year, and the year 2100 is a normal year.
[0044]
The day of January 1 of the leap year is the day after the day of January 1 of the previous year, and the day of January 1 of the year after the leap year is from the day of January 1 of the leap year. The next day of the week.
[0045]
On the other hand, the day of March 1 of the leap year is the day after the day of March 1 of the previous year, and March 1 of the year after the leap year is March 1 of the leap year. The day after the day of the week.
[0046]
For example, the days of January 1 of the year 2003 (normal year), the year 2004 (leap year), and the year 2005 (normal year) are Wednesday, Thursday, and Saturday, respectively, and the day of March 1 is Saturday, Monday and Tuesday. As described above, one of the January and February groups of leap years or the group of March to December needs to be displayed with a day of the week shifted from the normal calendar.
[0047]
As shown in FIG. 1 and FIG. 3, the numbers in the year display section 15 are arranged such that three normal years are arranged to the right of the leap year, and the next leap year is arranged by skipping one.
[0048]
For example, 2004 is a leap year, so the numbers “17”, “18”, and “19” are arranged to the right of the number “16”, and the number “20” that represents the next leap year is the label on the rightmost side. 14 position. When the position is shifted from the position of the rightmost label 14, the position of the leftmost label 8 is obtained. That is, the number “21” following the number “20” is arranged on the leftmost side, followed by the numbers “22” and “23”.
[0049]
On the other hand, the red number “1” and the number “2” of the date display board 2 are arranged at positions shifted counterclockwise by one from the black numbers “1” and “2”. Therefore, the year display unit 15 can continuously display four years of red numbers representing leap years. By remembering this rule, there is no table indicating the repositioning position. The label can be updated.
[0050]
Next, a method for using the perpetual calendar 1 will be described. When the perpetual calendar 1 is used, the date display board 2 is held with one hand, and the projection 18 of the day display board 3 is pinched and rotated with the other hand. And the number of the year display part 15 of the date display board 2 and the number of the day adjustment window 7 are match | combined. Then, it is visible from the day of the week display window 5. [0051]
For example, the calendar for June of 2003 is in the state shown in FIG. That is, “Day” and “SUN” are displayed on the leftmost side of the day of the week display board 3 visible from the day display window 5. That is, the column of the date “1” in the date display unit 6 corresponding to this is Sunday.
[0052]
On the lower side of the display of “day” to “soil” arranged in an arc shape, columns including date “1” to date “7” are arranged in an arc shape with the same radius. Accordingly, since the gap between the display of “day” to “sat” and the date “1” to date “7” can be arranged close to each other, the viewpoint for confirming a predetermined date and day of the week can be obtained. The travel distance is shortened and the day of the week can be confirmed in a short time.
[0053]
In the present embodiment, the center line in the column direction of each date is arranged in accordance with the center point of the upper end lines of the English displays “SUN” to “SAT” in the day of the week display window 5. You may arrange | position according to the center point of a line. It is also possible to match the center of Japanese display “Sun” to “Sat”.
[0054]

[0055]
A day-of-week emphasis line 22 is formed on the left side, upper side, and right side of the day-of-week display window 5 of the date display board 21. An adjustment window emphasis line 23 is formed around the day adjustment window 7 including the year display unit 15. The day-of-week emphasis line 22 and the adjustment window emphasis line 23 are formed in a circular arc shape on both sides of the eyelet 16 to enhance the design of the perpetual calendar 20. Further, the day of the week emphasis line 22 and the adjustment window emphasis line 23 are colored in flesh and blue, respectively, but other colors may be combined.
[0056]
The day of the week emphasis line 22 is not provided on the lower side of the day of the week display window 5, and the dates “1” to “7” are arranged close to the day of the week display window 5, so that a predetermined date and day of the week are confirmed. The moving distance of the viewpoint when doing so is shortened, and the day of the week can be confirmed in a short time.
[0057]
A holiday display unit 24 that displays national holidays is provided at the lower left of the year display unit 15, and a large month and a small month are described below the holiday display unit 24. A large month means a month having up to 31 days in one month, and a small month means a month having 30 days or less in one month.
[0058]
(Third embodiment)
FIG. 5 is a front view of a perpetual calendar according to the third embodiment of the present invention. As shown in FIG. 5, the fountain calendar 25 of the third embodiment uses a date display board 26 in which the material of the date display board 2 of the fountain calendar 25 of the second embodiment is replaced with a white board.
