DEVICE FOR DISPLAYING CLOCK DATES WITH SIGNS OF LARGE SIZE Russian patent published in 2017 - IPC G04B19/00 G04B19/247 

FIELD: physics.

SUBSTANCE: device includes a means for indicating tens, adapted to selectively display four separate characters, a means for indicating units, adapted to selectively display the numbers from 1 to 9 and zero. The means for indicating units includes a first upper plate (2) and the first lower plate (3), at least, partially overlapped in the display area (5). The first upper plate is adapted to the stepping rotation about an axis, and the sequence is located thereon, formed by eight characters evenly spaced circumferentially, from which seven characters are respectively represented by the numbers 1, 2, 3, 4, 5, 6 and 7 and an incomplete or absent eighth character associated with, at least, the first hole (A8E, A8G) opening the lower plate (3). The first lower plate is adapted to the stepping rotation about an axis and includes evenly spaced characters or character elements (P8, P9, P0), which are visible, when combined in the display area with the said, at least, one first hole of the first upper plate (2). The first upper plate (2) and the first lower plate (3) are designed to be sequentially displayed in the area (5) of the first full cycle formed by the sequence of numbers 1, 2, 3, 4, 5, 6, 7 displayed by the first upper plate, and then by the sequence of numbers 8, 9, 0, each of which is composed by overlapping one of the said characters or character elements (P8, P9, P0) of the first lower plate (3) on the said, at least, one hole (A8E, A8G) connected to the eighth character of the first upper plate (2) of the second full cycle, identical to the first full cycle and the third irregular cycle. The third cycle is composed of a sequence of numbers 1, 2, 3, 4, 5, 6, 7, completed in accordance with the current month length, first with all or a part of the said sequence of numbers 8, 9, 0, and then, if necessary, with number 1 displayed by the first upper plate.

EFFECT: simplifying the use of the updated device for displaying the clock characters at the end of a month comprising less than 31 days.
