Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a new accessory to be incorporated into a monthly calendar.

[Conventional technology and its problems]

The monthly calendar has one page for each month, or two pages for each month.
~3 months' worth is shown on one sheet. Also, the monthly calendar shows the weeks from the beginning of the month to the end of the month in parallel rows.

By the way, daily calendars are torn off every day, so you can easily tell what day it is today, but monthly calendars have a drawback that it is difficult to tell what day it is unless you remove a line every day. There is.

To address these shortcomings, a device was developed that made it easier to read the numbers by attaching an indicator to the calendar to indicate the date and number of months.
No. and Utility Model Application Publication No. 54-55448.

However, the technique proposed above has various problems in handling. In other words, in the former, a sliding indicator frame is attached to the month indicator rail showing the number of months on a perpetual calendar, and the month number is read through the window hole in the indicator frame, but the installation of the indicator frame is difficult. Since the upper edge of the indicator frame is simply bent to the back side and the bent portion is hung over the upper part of the moon indicator rail, there is a drawback that the indicator frame is easily moved by a small force or impact and is easily misaligned.

On the other hand, in the latter case, an iron plate is attached to the back side of the calendar, and the date display plate is attached to the calendar display using a magnet that attracts the plate. Also, simply displaying the date on a small display board will cause the displayed date to be lost.
For example, it has the disadvantage that it is difficult to identify which week of the month it falls on just by looking at the calendar.

Therefore, this invention has been devised to provide a month indicator for a monthly calendar that allows smooth movement and appropriate resistance to the indicator so that it can accurately indicate the date without shifting the position, and also allows for easy identification of the week in which the day is located. The purpose is to provide equipment.

[Means to solve the problem]

In order to solve the above problems, this idea
It consists of a band-shaped plate made of a transparent elastic material and a window frame that fits into the band-shaped plate and is slidable in the length direction. In addition, bent portions are provided on both sides in the width direction, the side edges of which are bent to the back side, and bent portions that fit on the outer surfaces of the bent portions are provided on both sides of the window frame, and the window at the bent portions is The bending angle with respect to the back surface of the frame is set to be smaller than the bending angle of the bent portion with respect to the back surface of the strip plate, and the window hole in the window frame is made large enough to expose only one day numeral.

[Effect]

This day indicator is attached to the month's calendar by the clamps at both ends, and is positioned above the week section, and the window frame is positioned at the day number section every morning.

In the above structure, the window frame slides on the band plate using the fitting between the bent parts on both sides and the bent part of the band plate as a guide, but due to the elasticity of the band plate, the window frame slides from the bent part to the bent part An outward force is applied and a resistance force is generated at the fitting portion of the two. For this reason, the window frame is prevented from wobbling and moves smoothly, and positional displacement is prevented at the stop position.

〔Example〕

FIG. 4 shows an example of a monthly calendar, and this calendar 1 shows three months' worth on one page.

Reference numeral 2 denotes a day indicator built into the calendar 1. As shown in FIG. .

The strip plate 3 is made of a transparent, inflexible thin plastic plate, and on both sides in the width direction there are bent parts 6 whose side edges are bent toward the back side so as to form a V-shape.
is formed. Further, at both longitudinal ends of the strip plate 3, clamping tongues 5 are formed by notches to clamp both side edges of the calendar 1.

The window frame 4 has bent portions 7 having the same cross section as the cross section of the strip plate 3 on both sides, and as shown in FIG. They are fitted and attached to the strip plate 3. This bent part 7
The bending angle α with respect to the back surface of the window frame 4 is smaller than the bending angle β of the bent portion 6 of the strip plate 3. A force that pushes them apart is applied, creating an appropriate amount of frictional resistance between the two. Therefore, when the window frame 4 is slid along the bent portion 6, the frictional resistance prevents the window frame 4 from rattling and allows smooth movement. It is securely locked at the stop position and positional shift is prevented.

The size of the window hole 8 in the window frame 4 is such that only one day numeral 9 can be exposed.

The date indicator of this embodiment has the above-mentioned structure, and the band plate 3 is attached to the calendar by pushing out the tongue pieces 5 at both ends to the back side as shown by the chain lines in FIG. and move the window frame 4 to the corresponding day part. In this case, as shown in FIG.
is located on the weekly part of the designated date and frames the entire weekly part, so that it is possible to easily identify in which week of the month the designated date is located by simply looking at the calendar 1.

〔effect〕

The day indicator for the monthly calendar of this invention is
It is easy to attach to a monthly calendar, and by moving the window frame each day, you can see at a glance what day it is, and the strip plate is located on the week number with the indicated date. This has the effect of making it easier to identify the week.

In addition, the elasticity of the band-shaped plate applies an appropriate amount of frictional force to the window frame, allowing the window frame to slide smoothly and stopping movement at the indicated position, making it possible to accurately indicate the date. There is.
