Description

Field of technology

The utility model relates to the field of watch technology, to watch mechanisms with pointer time indication, and, more specifically, to the production and use of complicated mechanical watches with the additional function of visually perceptible indication of the color of the Sun at the current time of day.

State of the art

Mechanical watches with a daily time indication are widely known, which measure equal periods of time and show the average time. Intervals can be hours, minutes, seconds or milliseconds. The smaller the difference between two identical measured intervals, the more accurate and better the watch is considered.

A day is a unit of time approximately equal to the period of rotation of the Earth around its axis.

Typically, a day is divided into periods of time such as day, night, dawn (sunrise), sunset (sunset).

It is generally accepted that:

the beginning of dawn - the time when the darkness of the night recedes and the time of morning twilight begins,

sunrise time (dawn) - the moment when the upper edge of the Sun appears above the horizon,

sunset time - the moment when the upper edge of the Sun disappears behind the horizon,

the onset of darkness is the time when evening twilight ends,

length of day (daylight hours) - the difference between the time of sunset and the time of sunrise,

length of night - the difference between the time of darkness of the previous day and the beginning of dawn of the current day.

It is known that the visually perceived color of the Sun changes throughout the day.

The concept of color refers to light perceived by human eyes in the form of electromagnetic waves of certain lengths that emanate from a light source or from observed objects.

Color does not exist in nature; it is the result of human visual perception of direct and/or reflected light.

The color of the Sun is the light perceived by human eyes when observing the Sun.

The sun is the source of light. It continuously emits electromagnetic waves in all directions, which in the visible range of sunlight (380-780 nm) cover the maximum of the solar radiation curve. At the top of the atmosphere, sunlight is almost 50% infrared light, 40% visible light and 10% ultraviolet light.

Part of the light radiation from the Sun falls on our Earth. These light waves can be visually perceived as direct light, reflected light, or absorbed. These light waves have different wavelengths, and our eyes can only see the part of them called "visible radiation" that determines the color of the objects we observe.

The light emitted by the Sun contains all wavelengths of the visible spectrum.

In space, the Sun appears white to the human eye. This is explained by the fact that there is no atmosphere in space and there is nothing for light to interact with. Therefore, there is no distortion of the color range of the Sun's light in space.

When light rays from the Sun enter our earth's atmosphere, different wavelengths of the spectrum of sunlight are scattered with different intensities at different times of the day as a result of differences in the length of the path of light rays in the atmosphere due to the spherical shape of the earth's surface. Therefore, due to the characteristics of human eyes, the Sun at different periods of the day is perceived by people as almost white, bright yellow, orange, red or reddish in color, that is, the visually perceived color of the Sun regularly changes during the day.

It is also known that human eyes are limited in the breadth of color perception by three types of photoreceptors. The most sensitive receptor L is responsible for the yellow-red range, M- and S-receptors perceive green-yellow and violet-blue shades of the light range, respectively. At the same time, the human brain is capable of transforming all signals from the photoreceptors of the eyes at a certain quantitative ratio to a single color balance - white color.

Taking into account the peculiarity of the perception of our organs of vision, during the daytime, daylight hours, the radiation of the Sun almost uniformly illuminates the L, M and S photoreceptors, and therefore our brain perceives each color in approximately the same amount, as a result of which we ultimately see direct radiation from the sun light white.

At the same time, when direct white light hits any objects, their surface reflects and absorbs different parts of the spectrum of sunlight, so different objects are perceived by our vision in reflected light as colored in different colors.

The visual perception of changes in the color of the Sun is due to the fact that the direct light of the Sun at the surface of the Earth's horizon acquires a yellow, orange or reddish tint due to molecular scattering of the short-wave part of the spectrum of the Earth's atmosphere.

Color The sun appears bright yellow, orange or reddish to the human eye after it rises or before it sets. This is due to the stronger influence of the Earth's atmosphere on the light emission from the Sun compared to midday.

At noon, short blue waves, as a result of interaction with air molecules in the upper atmosphere, are scattered many times before they appear to the human eye. This scattering effect gives the sky a blue color.

When the Sun is closer to the horizon at sunrise and sunset, light passes through more atmospheric molecules. Blue photons, as sunlight increases its path through the atmosphere, are scattered and leave behind the same low-energy yellow or orange color that makes the color of the sun at sunrise and sunset.

The sun's reddish hue occurs when there is dust or smoke in the air, usually as a result of windy weather, which scientists say enhances the scattering effect.

Before sunrise, at dawn, the colors of the Sun usually have more delicate shades, while sunset illuminates the planet with rays of rich red, burgundy, yellow, orange and very rarely greenish colors. This intensity of sunset colors is explained by the fact that during the day the earth's surface warms up, humidity decreases, the speed of air flows increases, and dust rises into the air, which together affects the more intense dispersion of sunlight at sunset.

Therefore, a visually perceived indication of the current periods of the day in which the Sun is visually perceived as a certain color with the corresponding intensity of solar radiation is relevant.

There are known clocks that show the time of sunrise and sunset.

A chronometer is known, which, to determine and indicate the time of sunrise and sunset and the position of the Sun, contains an hour hand that makes one revolution in 24 hours, a plate indicating the time of sunrise, containing a sunrise time indicator having a scale for indicating the time of sunrise, a plate indicating the time of sunset, containing an entry time indicator having a scale for indicating the entry time. In this case, one of these plates, either the plate for indicating the time of sunrise, or the plate for indicating the time of sunset, is configured to rotate, and the other plate is configured to rotate in the opposite direction to the specified first plate while maintaining an interlocked state with the specified first plate. The chronometer may contain a minute hand that makes one revolution per hour, and the hour hand may have a design symbolizing the sun [RU 2225632 G04B 19/26, G04B 19/22 Publ. 03/10/2004 Bulletin. No. 7. publ. PCT WO 00/77578 12/21/2000].

A clock is known that displays the current average solar time on earth, consisting of a device for displaying time, a structure made from a clock mechanism, a light source, in which the device for displaying time consists of a movable part with an image of the Earth’s surface, divided into 24-hour zones, and a fixed part parts are a dial with 24-hour digitization, and the light source has a position regulator for the longitude of the Earth map and a shutter shutter that ensures that the map illumination corresponds to the actual current midday illumination of the Earth's surface by the Sun on the days of the equinox. In this case, the light source is located inside the movable part of the dial, and the movable part of the dial is made in the form of a translucent / transparent part of the sphere, on which a map of the Earth is applied on a deformed scale with a view from the Earth's pole with 24-hour zones indicated by meridians, or the fixed part of the dial is made in in the form of a ring with 24-hour digitization, or the movable part of the dial rotates by a clock mechanism at a speed of 1 revolution per day inside the dial with the current time counted along the eastern meridian of the time zone relative to the dial [RU 101215 G04B 49/02 publ. 01/10/2011 Bulletin. No. 1].

There is a known method of indicating on a clock the period of day and the time of the period of day and a clock with an indication of the period of day and the time of the period of day, according to which, in order to improve the clarity of reading the time and to facilitate the limitation of the morning and day hours from the night hours, a watch containing a clock mechanism, a pointer mechanism, a dial and means for indicating the current time on the dial by means of the hour and minute hands, configured to indicate on the clock one of four periods of the day “night”, “morning”, “day”, or “evening” and indicating the current time of this current period of the day by means of the indication means time of the current period of the day, containing a disk of hour numbers, having 12 values of the hour numbers with the sequence of arrangement of the hour numbers on the disk - 12, 6, 1, 7, 2, 8, 3, 9, 4, 10, 5, 11 or 6, 12 , 7, 1, 8, 2, 9, 3, 10, 4, 11, 5, located under the dial coaxially with the hour hand and made with the ability to alternately move four times a day, once every six hours, forward and backward at an angle of up to 30 degrees with the ability to display in the dial windows the corresponding hour numbers of the current period of the day [RU 2502112) publ. 12/20/2013 Bulletin. No. 35].

A known mechanism for moving clock hands indicating the time of sunrise and sunset, which moves additional hands mounted on the central axes of a clock with a 24-hour dial, which indicate the time of sunrise and sunset with coordinates at a given point in the area, according to calculated astronomical algorithms for the movement of the Sun and the Earth, and works by converting the movement of the slider along a calculated closed groove on the impeller, which performs a rotational movement, into the reciprocating movement of additional arrows using connecting rods adjusted in length to a certain geographical latitude of the terrain point and a guide bar with a groove for reciprocating movement of the slider, the impeller with a calculated groove performs one revolution per year through a transmission connected to the main mechanism of the watch. In this case, the mechanism has a device for monitoring and adjusting the current date of operation of the device in the form of an additional disk with a calendar of months of the year and a device for setting the time zone of a location point, which changes the shift of the mechanism according to the difference in time between geographic noon and hourly noon at a given location point with an indication in the dial window hours [RU 123185 G04B 19/26 Publ. 12/20/2012 Bulletin. No. 35].

The closest in technical essence and the result achieved when using it (prototype) is a watch with color indication of light, dark and twilight periods of the day, containing a dial, a clock mechanism, a pointer mechanism and a mechanical means of indicating periods of the day, in which the mechanical means of indicating periods of the day is made with the possibility of cyclically changing the color, color intensity or brightness of the color of the dial according to the cyclic alternation of periods of the day, for example, according to the cyclic alternation of the periods of the day before noon and after noon, day and night, light and dark, or morning, afternoon, evening and night. In this case, the watch is made with the possibility of indicating periods of the day by means of cyclic rotational combination of an alternating partially transparent and partially colored image with one color and an opaque alternating image colored with at least two colors to obtain a single combined image on the watch dial, so that in one of the periods of the day it is ensured the formation of a combined image obtained by alternating some colors, and in another period of the day the formation of a combined image obtained by alternating other colors is ensured, and the alternating partially transparent and partially colored image is made motionless in the form of alternating slits of an image painted on the dial painted in one color, and the alternating The image, painted in at least two colors, is made movable on a disk located under the dial with the possibility of bringing it into rotation from the clock mechanism with cyclic jump-like or smooth movements. In this case, the alternating partially transparent and partially colored image is made stationary in the dial in the form of a transparent material located in it or under it with an alternating transparent and alternating image painted with one color, and the alternating image painted with at least two colors is made movable on the one located under the dial disk with the possibility of bringing it into rotation from the clock mechanism with cyclic jerky or smooth movements [RU 2543679 G04C 17/00 publ. 03/10/2015 Bulletin. No. 7 (prototype)].

The common disadvantages of the above analogues and the prototype is their lack of a function of visually perceptible indication of the color and position of the Sun on the dial of a mechanical watch.

In the scope of the search, no mechanical watches with the function of indicating the color and position of the Sun at different periods of the day on the dial of a mechanical watch were found.

Task and technical result

The objective of this utility model and the technical result obtained from the use of the utility model are to create a simple, easy-to-manufacture, but reliable mechanical watch with a 24-hour division of the dial and a corresponding 24-hour indication of the current time of day, which allows you to dial and without deteriorating the readability of the current time of day on the dial, display on the dial the visually perceived corresponding color of the Sun at the current time of day.

Various well-known and traditional watchmaking technologies, materials and design solutions, usually used in watchmaking [Kharitonchuk A.P. “Reference book on watch repairs”, 1977, “Light Industry”, Moscow; Belyakov I.S. “Clock mechanisms” 1957, “Mashgiz”; Romanov A.D. Design of time devices. M., 1975; Tarasov S.V. Watch production technology, M., 1963; Popova V.D., Goldberg N.B. The device and technology of watch assembly. M., 1989].

The proposed watch can be primarily used at the equator and at near-equatorial, southern latitudes relative to the north pole of the Earth, where depending on the time of day and the corresponding position of the Sun in the sky, not only the color of the Sun changes significantly, but also the amount of solar radiation (ultraviolet and infrared radiation) at times physically dangerous, especially at midday, for unadapted people who came from distant places from the equator.

The proposed watch can be used to quickly determine the position of the Sun in the sky during the day and for the purposes of observing sunrise and sunset, and for the purpose of performing certain work at a relatively comfortable time of day, since it is known that at the equator and near-equatorial (southern relative to the north pole) latitudes of the Earth, depending on the time of day and the corresponding position of the Sun in the sky, not only the color of the Sun changes significantly, but also the amount of solar radiation (ultraviolet and infrared radiation), which is at times physically dangerous, especially at noon, for people coming from northern latitudes and not adapted to intense solar radiation at the equator and southern latitudes.

In addition, for these places it is important to determine and use, for example, for observation purposes or to perform certain work at a relatively comfortable time of day, the time of sunrise and sunset, that is, to quickly determine the position of the Sun in the sky during the day, which can be done using the proposed clock by observing the corresponding color and position of the Sun on the clock face at the current time of day.
