Abstract

A multi-year calendar containing a base with slotted windows and a rotating disk coaxially mounted beneath it, on which calendar information is placed, characterized in that on the base there is a table with indexes of numbers and a circular annual scale, and on the disk there is a circular table with indexes of days of the week and table with month indicators.

Description

Multi-year calendar

The utility model refers to “perpetual calendars and can be used to display chronological (calendar) information of various calendar systems.

The prior art “eternal perennial calendars made in the form of several rotating disks with slotted windows, on the surfaces of which there is an annual flap, indicators of months, numbers, days of the week (see USSR copyright certificates No. 187392, MKI G09D 3/00, 1966 .; No. 955176, MKI G09D 3/02, 1982; No. 1462401, MKI G09D 3/08. 1989; No. 1758665, G09D 3/06, 1992; US patent No. 3487572, ШШ 40-115, 1989; UK patent No. 1555410, MKI G09D 3/06, 1979; German patent No. 1968461, MKI G09D 3/06, 1972; French application No. 2494486, MKI G09D 3/08, 1989).

These calendars mainly differ in the number of disks and the location of the calendar information and are characterized by the relative complexity of determining the required date.

Closest to the claimed solution is a multi-year calendar,

manufactured by the MZM plant (Moscow, 1969), which contains a base with slotted windows and a movable, rotating disk coaxially mounted underneath it, while on the base there are tables with indexes of numbers and months, and a table with indexes of days of the week is placed on the rotating disk and annual flimsy.

The disadvantage of this design can be attributed to some complexity of use associated with the definition of the month, which is due to the location in one column of the table of indexes of several months.

The utility model is aimed at creating a compact, easy-to-define calendar information for a multi-year calendar suitable for displaying

various calendar systems.

The solution to this problem is ensured by the fact that in a multi-year calendar containing a base with slotted windows and a rotating disk coaxially mounted beneath it, on which calendar information is placed, in accordance with the proposed solution, on the base there is a table with indexes of numbers and a yearly circular, and on a rotating disk are a circular table with

pointers to the days of the week and tablets with month pointers.

The proposed arrangement of calendar information allows enough

simply, by combining the month and year, determine the days of the week.

In FIG. 1 shows a general view of a multi-year calendar; in FIG. 2, the base is shown separately; FIG. 3 - a rotating disk.

The multi-year calendar contains a base 1, under which a rotating disk 2 is coaxially mounted. On the surface of the base 1 there is a circular annual flake 5 and a table 6 with indexes of numbers, and at the base 1 there are slotted windows 3 in the form of sectors for viewing information about the months and a window- slot 4 in the form of a ring segment to determine the days of the week. On the surface of disk 2 there is a circular table 7 with indexes of the days of the week and table 8 with indexes of the months, the names of which are written in

glad) in the direct beam direction with a certain positioning relative to the days of the week and taking into account the displayed years.

For the Gregorian calendar system, including leap years, and having a cycle of 28 years, the annual flank of 5 is divided into seven groups, separated by spaces, and accordingly, in the base 1 there are seven slot windows 3 in the form of sectors, and on table 8 except the names of the twelve months of the year two additional months of January and February are shown, which are used to form a calendar in leap years.

SHR

The inventive multi-year calendar provides a calendar

information as follows. The user, rotating the disk 2 relative to the base 1,

sets it to a position where the 3-month determined through the slit window on table 8 is opposite the determined year on the annual scale 5. When the year and the month are combined, the circular table 7 moves with the indexes of the days of the week relative to table 6 with the indexes of numbers whose relative position through the slot window 4 displays the current calendar information.

The proposed utility model can be used to display

chronological information of various calendar systems (Gregorian,

Julian, Eastern, Islamic, etc.), as well as to display other useful

information (holidays, famous 11th days, religious events, etc.).
