Abstract

PURPOSE:To see a constellation of a specified time of a year at a glance, by interlocking a rotation of a revolving shaft of a clock and a rotation of a constellation plate, so that the constellation place performs one rotation by one day of a fixed star day. CONSTITUTION:A star group which can be seen over one year in a specified place in Japan is drawn successively along the circumferential direction on a discoid constellation plate 1, and many teeth 2 engaged with a driving gear 11 are formed like a gear on its outside circumferential face. A surface plate 4 and a back plate 5 of a body 3 are connected as one body by holding a prescribed interval by a connector 6, an elliptical window 7 is provided on the surface plate 4, and the constellation plate concerned 1 is supported so as to be freely rotatable through a supporting shaft 8 between the surface plate 4 and the back plate 5 of the body 3, so that the about lower half part of the constellation plate 1 can be seen from the window concerned 7. The size of the window 7 to the constellation plate 1 corresponds to a field of view which can be observed when looking up to the star group in a night sky from on the earth.

Description

[Detailed description of the invention] In a typical clock, the long hand makes 24 revolutions and the short hand makes 2 revolutions in a day.

It is organized according to so-called solar time (24 hours in a day).

By the way, when viewed from the Earth, the stars in the night sky appear to be orbiting around the Earth. The position of the stars is changing from moment to moment. These stars move in the same way as the sun rises in the east and sets in the west, but while the sun orbits the entire sky once every 24 hours, these stars take 23 hours, 56 minutes, and 4 seconds. Go around once.

In other words, if you want to see the same star in the same position in the night sky every day, you should look at it at a time that advances by 6 minutes and 56 seconds each day. For example, if you want to see a star shining in the night sky at 20:00 in the same position tomorrow in the night sky, it will be 19:56.
That's 4 minutes and 4 seconds. If you look up at the night sky in each of the four seasons: summer, winter, autumn, and spring, the 6 minutes and 56 seconds of progress each day will add up, and different stars will be shining there.

The invented constellation clock links the rotation of the long hand of a commercially available clock with a disc displaying constellations, etc., so that the position of the star at any given time can be seen at a glance as the position of the star changes from moment to moment. This is what I did.

Name of the invention Constellation hour hand 2, Claims main body 3, front plate 4 A disk-shaped constellation board 1 is provided with an elliptical J [7], and a disk-shaped constellation board 1 in which star groups that can meet over a year at a specific point on the earth are arranged sequentially along the circumferential direction. When the N seat plate 1 is rotatably supported between the front plate 4 and the back plate 5 of the main body 3 so that its lower half can be seen from the 11[7], and is attached to the main body 3. A constellation hour hand characterized in that the rotation of the rotation axis of IIt9 and the @ rotation of the constellation plate 1 are linked to each other so that the constellation plate l rotates once in a day on a sidereal day. 3. Details of the invention. Explanation: The present invention allows the rotation of the rotation axis of the hour hand and the rotation of the constellation plate to be linked so that the constellation plate rotates once per fixed day. The hour hand is a constellation shaped like a bird's teeth.The group of stars that appear in the night sky appears to be orbiting around the upper Earth when viewed from the Earth. When the sun rises in the east and sets in the west, it undergoes a similar movement.The sun appears to orbit the earth once every 24 hours, but the above star group is observed during the so-called phoenix period (one day is It apparently orbits the upper Earth once every day (23 hours, 56 minutes, 4 seconds).For this reason, if you want to see the same star group in the same position every day, you will have to look at the time that has advanced to 3 minutes, 56 seconds. , conversely, m of the night sky at the same time every day
If you look at the group, you will not see the same phoenix in the same position, and this is why the star group visible in the night sky throughout the year is l1i1vCII4. On the other hand, the general hour hand is arranged according to the so-called solar day (24 hours in a day), with the long hand making 24 revolutions and the short hand making 2 revolutions in 24 hours. The constellation hour IT according to the present invention is based on the rotation of the rotation axis of the hour hand and the
By interlocking the rotation of the L seat plate so that the N seat plate rotates once per day, the jl of a specific date and time in -year
The seat can be seen at a glance, and the present invention will be explained in detail below with reference to Examples. As shown in the figure, on the disc-shaped constellation board l, star groups that can be seen for a year in specific locations in Japan are drawn sequentially along the circumference, and on its outer surface are the star groups that can be seen throughout the year. A large number of teeth 2 are formed to mesh with the drive gear 11, forming a gear shape. The front plate 4 and the back plate 5 of the main body 3 are connected together by a connector 6 with a predetermined distance maintained, and the courtesy call 4 is provided with an oval window 7 through which the constellation plate l can be seen. The constellation plate 1 is rotatably supported via a support shaft 8 between a front plate 4 and a back plate 5 of the main body 3 so that substantially its lower half can be seen. The size of [7] with respect to the constellation plate l corresponds to the field of view that can be observed when looking up at the star group in the night sky from the earth. In addition, 1t9 is normally attached to the back plate 5 of the main body 3,
A drive gear (2) is fitted and fixed on the rotation shaft 10 of the long hand of the hour hand 9, and this drive wheel 11 and the teeth 2 provided on the outer periphery of the constellation plate (1) are meshed with each other, so that the rotation shaft (10) of the long hand of the hour hand 9 is engaged. The jl seat plate 1 is configured to be rotated by the rotation of the jl seat plate 1. Here, the number of teeth z1 of the drive gear 11 and the number of teeth z2 of the teeth 2 provided on the outer periphery of the constellation plate l may be set to values such that the constellation plate l rotates once in one sidereal day. , for example Zl
= 15, Z2:359, the jl seat plate l rotates once at 23:01 & 156 minutes, which approximates the day of Kohoji. Also, in the above embodiment, Jim! due to the meshing of the gears! I made the plate l rotate, but it was a disk-shaped constellation bowl! In addition to applying anti-slip treatment to the outer surface of the
A ** wheel (not shown) is fitted and fixed on O, and the j
The i-seat plate l may be configured to be rotated. In this case, the outer diameter of the constellation plate 1 and the outer diameter of the friction wheel may be configured such that the constellation plate 1 rotates once in one day of the solar eclipse or a time approximated thereto. As described above, the constellation hour hand according to the present invention has a disk-shaped constellation plate in which star groups that can be seen for a year at a specific point on the earth are placed sequentially along the circumference. It is linked to the rotation of the rotation axis of the hour hand so that it rotates once in a day, so the number of star clusters seen in the same poem every day is small (about 1") and then moves to -gIa at a specific date and time in the year. It is extremely convenient to be able to see the visible M constellations at a glance on the constellation board. 4.
