Description

[Technical Field]

[0001] This invention relates to a wall calendar in which calendar information for multiple months is displayed in a common size for each month. [Background technology]

[0002] Conventionally, calendars (also called "wall calendars") that are used by pinning them to a wall in an office or to a partition in an office are known. Known wall calendars include calendars that display only calendar information for the current month, and calendars that display calendar information for multiple months, including the current month, previous month, and next month (also called multi-month display calendars). Conventional multi-month display calendars include calendars in which the display size of the previous and next months is smaller than that of the current month, improving the visibility of the current month and the convenience of writing schedules (see, for example, Patent Document 1), and calendars in which the display size of each month is the same (hereinafter also called "common month display calendars"). Known common month display calendars include, for example, calendars in which month displays are arranged horizontally (see, for example, Patent Documents 2 and 3) and calendars in which month displays are arranged vertically (see, for example, Patent Document 4). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Registered Utility Model No. 3226838 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-116727 [Patent Document 3] Registered Utility Model No. 3066066 [Patent Document 4] Japanese Patent Application Laid-Open No. 2009-6670 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional wall calendars, when the month changes, it is necessary to tear off the paper for that month, and conventional common-month calendars in particular have problems due to the change in the order of the months when this occurs. For example, a wall calendar 100 shown in FIG. 8 is known, and this wall calendar 100 has the following problems. The wall calendar 100 has a calendar paper 120 with month display sections 101, 102, and 103 for three months. Perforations 104 and 105 are formed on the calendar paper 120 between each of the month display sections 101, 102, and 103. The month displays of the month display sections 101, 102, and 103 are January, February, and March of 2025, respectively, and are arranged in order from bottom to top. Therefore, the order of the months in the case of FIG. 8 is 'January,' 'February,' and 'March,' from bottom to top.

[0005] Then, when the date passes the last day of January and enters February, and the lower portion (corresponding to month display portion 101) of calendar paper 120 is torn off from perforation 104, month display portion 106 of calendar paper 121 underneath calendar paper 120 appears, as shown in Figure 9. Because the month displayed in month display portion 106 is April 2025, the order of months in Figure 9 is 'April,' 'February,' and 'March,' from bottom to top. Furthermore, when the date passes the last day of February and enters March, and the lower portion is torn off from perforation 105, month display portion 107 of calendar paper 121 appears, as shown in Figure 10. Because the month displayed in month display portion 107 is May 2025, the order of months in Figure 10 is 'April,' 'May,' and 'March,' from bottom to top.

[0006] Thus, in the case of the wall calendar 100, the months were initially arranged vertically from the bottom up as 'January,' 'February,' and 'March,' in numerical order, but each time a portion of the calendar paper was torn off to change the month, the months were arranged out of numerical order, changing every month to 'April,' 'February,' 'March,' 'April,' 'May,' and 'March.' This meant that the pattern of moving one's viewpoint up and down had to be changed each time the month changed, which caused inconveniences such as reduced visibility of the months and dates, and making it difficult to check dates and days of the week that spanned months, such as between the current month and the previous month, or between the current month and the next month.

[0007] The purpose of this invention is to solve the above-mentioned problems and to provide a wall calendar in which the order of months along the vertical direction is always maintained in a fixed pattern even when part of the calendar paper is torn off with each month, and in which the date and day of the week can be easily checked and understood at any time. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the present invention provides a wall calendar comprising a plurality of calendar papers and a binding device binding the plurality of calendar papers, the plurality of calendar papers including three first calendar papers and one second calendar paper, each displaying calendar information for four consecutive months of the year and month, the first and second calendar papers each having a calendar display section displaying the calendar information and a binding margin connected to the calendar display section via perforations and positioned above the calendar display section, the calendar display section of the first calendar paper having two strips divided into two halves across a vertical pre-cut line that intersects the width direction of the binding margin, each of which has a two-strip structure with the same size and displaying calendar information for two months, the calendar display section of the second calendar paper having a single sheet structure displaying calendar information for four months, the three first calendar papers stacked on top of the second calendar paper, each with the perforations aligned with the bottom edge of the binding device.

[0009] In the wall calendar, it is preferable that the calendar information on each of the multiple calendar sheets is arranged in a forward year-month display in which the calendar information is arranged in numerical order from top to bottom and in year-month order from left to right.

[0010] It is also preferable that two holes are formed through the binding device and the binding margins of the multiple calendar sheets, and one end and the other end of a hanging string are inserted into each of the holes.

[0011] Furthermore, it is preferable that calendar information for one year is displayed on the surface of the binder.

[0012] Furthermore, it is preferable that when the left strip of the two strips of the topmost paper, which is located at the top of the first calendar paper, is torn along the perforation, the calendar information displayed on the left strip of the two strips of the lower paper, which is located next to the topmost paper, appears, and a reverse year-month display is formed in which the calendar information is arranged in year-month order in a right-left direction from the right strip of the two strips of the topmost paper to the left strip of the lower paper. [Effects of the Invention]

[0013] As detailed above, according to this invention, even if a portion of the calendar paper is torn off with each month, the order of the months along the vertical direction is always maintained in a fixed pattern, and a wall calendar can be obtained that allows the date and day of the week to be easily checked and understood at any time.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same elements are designated by the same reference numerals, and redundant description will be omitted.

[0016] A wall calendar 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 6. Figure 1 is a front view of the wall calendar 1, Figures 2(a), (b), (c), and (d) are front views of four calendar sheets 11, 21, 31, and 41, respectively, with the calendar information omitted, and Figure 3 is an exploded perspective view showing a paper set 51 and a binder 61. Figure 4 is a front view showing the state in which a portion of the left strip 16 of the calendar sheet 11 has been turned up and the state after the left strip 16 has been cut off, and Figure 5 is a front view showing the state in which a portion of the right strip 17 of the calendar sheet 11 has been turned up and the state after the right strip 17 has been cut off. Figure 6 is a front view showing the state in which a portion of the left strip portion 36 of the calendar paper 31 has been turned up, and the state after the left strip portion 36 has been cut off. Figure 7 is a front view showing the state in which a portion of the right strip portion 37 of the calendar paper 31 has been turned up, and the state after the right strip portion 37 has been cut off.

[0017] 1 and 3, the wall calendar 1 has four calendar papers 11, 21, 31, and 41 and a binding device 61. The four calendar papers 11, 21, 31, and 41 are stacked from the top (front side) to form a paper set 51 in such a way that the calendar papers 11, 21, 31, and 41 do not shift, and the upper part of the paper set is bound together using the binding device 61.

[0018] Of the four calendar papers 11, 21, 31, and 41, three of them (11, 21, and 31) correspond to the first calendar paper in this invention, and calendar paper 41 corresponds to the second calendar paper in this invention. The four calendar papers 11, 21, 31, and 41 are made of high-quality paper or the like and are formed into a vertically long rectangle. Although the calendar information displayed is different, each of them displays calendar information for four consecutive months of the year and month.

[0019] As shown in Figures 2(a), (b), (c), and (d), calendar sheets 11, 21, 31, and 41 display calendar information for November and December 2025, January and February 2026, March to June 2026, July to October 2026, November and December 2026, and January and February 2027 (each displaying four months in total). The calendar information includes the year, month, day of the week, and date. For example, in the case of calendar sheet 11, as shown in Figure 1, the years '2025' and '2026' are displayed at the top of the left and right sides (in both cases, the last two digits '25' and '26' are displayed larger than the first two digits), and the months are displayed with circled numbers '11', '12', '1', and '2', along with their English equivalents such as 'November', and the days of the week and dates are displayed below.

[0020] As shown in Figures 2(a), (b), (c), and (d), the calendar papers 11, 21, 31, and 41 each have a calendar display section 12, 22, 32, and 42 on which calendar information is displayed, and binding margins 14, 24, 34, and 44 that are connected to the calendar display sections 12, 22, 32, and 42 via perforations 13, 23, 33, and 43 and are located above the calendar display sections 12, 22, 32, and 42.

[0021] The calendar display sections 12, 22, and 32 of the calendar paper 11, 21, and 31 are divided into two halves, left and right, by a pre-cut line 15, 25, and 35 in the center of the width, resulting in two strips 16 and 17, 26 and 27, and 36 and 37. Each strip 16, 17, 26, 27, 36, and 37 has the same size and displays calendar information for two months. Of each strip 16, 17, 26, 27, 36, and 37, the left strip 16, 26, and 36 correspond to the left strip, and the right strip 17, 27, and 37 correspond to the right strip. In each strip, the months are displayed in numerical order, from top to bottom. The calendar paper 11, 21, and 31 have a two-strip structure with two such strips.

[0022] Like the calendar papers 11, 21, and 31, the calendar paper 41 displays calendar information for two months on the left half and two months on the right half (four months in total), and the months are displayed in numerical order from top to bottom on both, but it has a single-sheet structure with no pre-cut lines.

[0023] As shown in Figures 2(a), (b), (c), and (d), the calendar papers 11, 21, 31, and 41 all have a forward-oriented year-and-month display Fd for displaying calendar information. The forward-oriented year-and-month display Fd refers to a display in which calendar information is arranged in the order of month numbers from top to bottom and in the order of years and months from left to right. For example, as shown in Figure 2(a), in the case of the calendar paper 11, the left and right strips 16 and 17 display the calendar information for November and December 2025 and January and February 2026, respectively, arranged in the order of month numbers from top to bottom and in the order of years and months from left to right, such as December 2025 in the left strip 16 to January 2026 in the right strip 17. The calendar papers 21 and 31 also have a forward-oriented year-and-month display Fd.

[0024] 3, three calendar papers 31, 21, and 11 are stacked in order on top of calendar paper 41, with calendar paper 11 placed on top to form paper set 51. Binding margins 14, 24, 34, and 44 are placed inside binder 61 so that perforations 13, 23, 33, and 43 of each paper are aligned with bottom end 61b of binder 61.

[0025] 3, the binder 61 is made of cardboard or the like that is thicker than the calendar papers 11, 21, 31, and 41, and is formed in a bifold shape with the same width as the calendar papers 11, 21, 31, and 41. Both the front and back surfaces 62a and 62b have the same dimensions as the binding margins 14, 24, 34, and 44, and all four calendar papers 11, 21, 31, and 41 are bound together with the binding margins 14, 24, 34, and 44 sandwiched between them.

[0026] 1, a calendar information display section 66 is formed on the surface section 62a of the binder 61. In the calendar information display section 66, calendar information for one year (for the year 2026 in the case of FIG. 1) is displayed at a smaller size than that of the calendar papers 11, 21, 31, and 41. Although omitted in FIG. 1, the calendar information includes the month and date, but not the day of the week, as in the month and date display 66b.

[0027] Furthermore, as shown in FIG. 1 , the wall calendar 1 has two through-holes 63, 64 that penetrate the binding device 61 and the inner binding margins 14, 24, 34, 44. One end and the other end of a hanging string 65 are inserted through each of the through-holes 63, 64. The hanging string 65 can be, for example, a twisted string made by twisting together multiple threads. By providing knots at both one end and the other end of the hanging string 65, the hanging string 65 is prevented from falling off the binding device 61.

[0028] The wall calendar 1 configured as described above is used by hanging the hanging string 65 from a fastener (such as a pin or nail) fixed to the wall (not shown). In the case of the wall calendar 1 shown in Figure 1, the calendar information on the left strip portion 16 is November and December 2025, so in the following explanation it is assumed that December 2025 is the current month, November 2025 is the previous month, and January 2026 is the next month.

[0029] If the calendar advances beyond the last day of December 2025 to January 2026, the calendar information in the left strip 16 will no longer be necessary. In this case, as shown on the left side of FIG. 4 , the calendar display section 12 of the calendar paper 11 is divided into a left strip 16 and a right strip 17 along a pre-cut line 15. This allows the left strip 16 to be turned up separately from the right strip 17 (i.e., only the left strip 16) and separated from the binding margin 14 along the perforation 13. When the left strip 16 is separated, the left strip 26 of the calendar paper 21 underneath is revealed. Because the left strip 16 and the left strip 26 are formed to have the same size, four months' worth of calendar information is displayed, as in the case of FIG. 1 (before the left strip 16 is separated), as shown on the right side of FIG. 4 .

[0030] In the right strip 17, the calendar information is arranged vertically in January and February 2026, while in the left strip 26, the calendar information is arranged vertically in March and April 2026. However, the displayed calendar information is arranged in year-month order from the right strip 17 to the left strip 26. In other words, when the left strip 16 of the topmost calendar paper 11 is separated, the left strip 26 of the next calendar paper 21 (corresponding to the lower paper in this invention) is revealed, and the calendar information changes its order from left-to-right (from left to right) to right-to-left (from right to left), forming a reverse year-month display Rd. The reverse year-month display Rd refers to a display in which the calendar information is arranged in year-month order from January and February 2026 on the right to March and April 2026 on the right, as shown on the right side of Figure 4. Even in this case, the month display remains unchanged, with January and February 2026 in the left rectangular portion 26 and March and April in the right rectangular portion 17.

[0031] If the calendar advances to March 2026, passing the last day of February 2026, the calendar information in the right rectangular portion 17 becomes unnecessary. In this case, as shown on the right side of Figure 5, the right rectangular portion 17 is separated from the binding margin 14 along the perforation 13, revealing the right rectangular portion 27 of the calendar paper 21 underneath. Then, as shown on the left side of Figure 5, the topmost paper becomes only the calendar paper 21, and the calendar information is arranged in year-month order from left to right, forming the forward year-month display Fd again.

[0032] Thereafter, as the calendar progresses, a forward year-month display Fd and a backward year-month display Rd are similarly formed. If, as the calendar progresses, the date passes the last day of August 2026 and advances to September 2026, the calendar information in the left strip portion 36 of the topmost calendar paper 31 becomes unnecessary, as shown on the left side of Fig. 6. When the left strip portion 36 is separated from the binding margin 34 along the perforation 33, a calendar paper 42 corresponding to the lower paper appears, as shown on the right side of Fig. 6, and a backward year-month display Rd is formed. Furthermore, if, as the calendar progresses, the date passes the last day of October 2026 and advances to November 2026, the calendar information in the right strip portion 37 becomes unnecessary. Therefore, as shown on the right side of Figure 7, when the right strip portion 37 of the topmost calendar paper 31 is separated from the binding margin 34 along the perforation 33, the entire calendar display portion 42 of the calendar paper 41 appears, and the forward year and month display Fd is again formed, as shown on the left side of Figure 7.

[0033] As described above, the calendar information displayed on the wall calendar 1 changes as the calendar progresses by separating the left strips 16, 26, 36 and the right strips 17, 27, 37 from each of the calendar sheets 11, 21, 31. In either case, the vertical order of the months is always maintained in a fixed pattern, in the order of the numbers from top to bottom. Unlike the conventional wall calendar 100, the vertical order of the months in the wall calendar 1 according to the embodiment of the present invention does not change every month. Therefore, there is no need to change the pattern of moving the viewpoint up and down with each new month, and the visibility of the dates is not impaired, making it easy to understand and check dates and days of the week across months.

[0034] Furthermore, in the wall calendar 1, the forward year-month display Fd may be formed in some cases, and the backward year-month display Rd may be formed in other cases, so the left-right arrangement of the months may change, but the vertical arrangement of the months remains unchanged, so the visibility of the dates is not reduced.

[0035] Of the calendar papers 11, 21, 31, and 41, the calendar papers 11, 21, and 31 have a two-strip structure, while only the calendar paper 41 has a single-sheet structure. The calendar paper 41 could also be formed with a two-strip structure, but in that case, all of the calendar papers 11, 21, 31, and 41 of the wall calendar 1 would be formed with a two-strip structure. In that case, all of the calendar papers 11, 21, 31, and 41 would be separated into a left strip and a right strip, which would tend to move together, resulting in an unstable display state. In contrast, in the wall calendar 1, the calendar paper 41, which is located at the bottom, is formed with a single sheet, so the calendar papers 11, 21, 31, and 41 as a whole do not separate into a left strip and a right strip and move together, ensuring a stable display state.

[0036] The calendar papers 11, 21, and 31 are each divided into left strips 16, 26, and 36 and right strips 17, 27, and 37 by pre-cut lines 15, 25, and 35, respectively. This allows the left strips 16, 26, and 36 to be easily separated from the right strips 17, 27, and 37, and this separation can be performed reliably. While it would be possible to separate the left strips 16, 26, and 36 separately using perforations instead of pre-cut lines 15, 25, and 35, this would require unfolding the calendar papers 11, 21, and 31 along the perforations, which would be time-consuming and could potentially tear the calendar papers 11, 21, and 31. In contrast, the wall calendar 1 eliminates this inconvenience because the calendar papers 11, 21, and 31 are already divided by the pre-cut lines 15, 25, and 35.

[0037] The wall calendar 1 has a hanging string 65. Instead of the hanging string 65, a through-hole (not shown) that passes through the binding device 61 and the inner binding margins 14, 24, 34, and 44 can be formed in the center of the width direction, and the wall calendar 1 can be hung on the wall by passing a pin through the through-hole.

[0038] However, in this case, when the left strips 16, 26, and 36 are detached, the left-right weight balance of the wall calendar 1 is disrupted, and the wall calendar 1 is likely to become tilted. In this regard, the wall calendar 1 has a hanging string 65, which allows it to be hung on a wall. When the hanging string 65 is used to hang the wall calendar from a pin or nail, friction occurs between the hanging string 65 and the surface of the pin or nail, restricting the movement of the hanging string 65 and, as a result, preventing movement when the weight balance is disrupted. When the left strips 16, 26, and 36 are detached and the left-right weight balance of the wall calendar 1 is disrupted, the position of the hanging string 65 on the pin or nail can be adjusted, and in this way the wall calendar 1 can be maintained in a parallel hanging state.

[0039] The above description is of the preferred embodiment of the present invention, and does not limit the device and method of the present invention, and various modifications can be easily implemented. Furthermore, the present invention also includes devices or methods that are configured by appropriately combining the components, functions, features, or method steps of each embodiment. [Industrial Applicability]

[0040] By applying this device to a wall calendar, even if part of the calendar paper is torn off with each month, the order of the months along the vertical direction will always be maintained in a consistent pattern, making it easy to check and understand the date and day of the week at any time. This device can be used in the field of wall calendars. [Explanation of symbols]
