DETAILED DESCRIPTION Hereinafter, embodiments of the celestial sphere of the present invention will be described in detail with reference to the accompanying drawings.

First embodiment

1 and 2 show schematic partial exploded perspective views of a celestial sphere in accordance with one preferred embodiment of the present invention.

As shown, an embodiment of the celestial sphere of the present invention includes a rim sphere 8, a disc member 10, transparent spheres 12a and 12b, transparent spheres 12a and 12b, and the like. It comprises a support rod (6) for supporting and a support means (2) for supporting it as a whole.

The rim spheres 8 are formed by combining a plurality of rigid rims bent in a ring shape at equal intervals and coupled to the same vertices 13a and 13b. Here, each rim may be used as an index indicating the meridian or time zone of the celestial body. In addition to the equal interval, the relative angle of each rim may be displayed on the rim surface based on one rim.

The disc member 10 is a rigid circular flat plate whose diameter is substantially similar to the diameter of the rim sphere 8 and is supported over the inside of the rim sphere, and can be inclined at various angles inside the rim sphere. .

This disc member serves as a horizontal plane that plays an important role in understanding the movement of the celestial body. Since the horizontal plane is different for each province, the disc member is inclined to fit the latitude of the province to adjust the inside of the rim. Lost and supported. This disc member may also serve as an equatorial plane or ecliptic plane, depending on the purpose of use.

Since the center of the disc member substantially coincides with the center of the transparent spheres 12a and 12b, this becomes a standard for observing the celestial body. Therefore, the learner psychologically places a doll or earth model symbolizing the observer at this position. It makes it easier to imagine and understand the movements of celestial bodies. If necessary, a fixing part for fixing such a model in the center of the disc member, for example, in Figure 1, for example, it is possible to add a hole (15) for fitting the model, if the fixing part having the same function as the protruding groove Etc. Any form is possible.

In addition, the angle of the circumferential direction may be more easily added to the upper surface of the disc member by adding an angle meter 16 and the like which are radially divided by 360 degrees.

The transparent spheres 12a and 12b are made of a transparent plastic material such as acryl and the like to display an arbitrary object on the surface thereof, or to display a planet's orbit, the celestial equator, ecliptic, white horoscope or constellation. Means.

A portion of the transparent sphere is opened so that the user can put his hand through it to adjust the position of the aforementioned disc member or to operate auxiliary tools such as a protractor, a compass, a doll and the like as needed. Consists of. Only one opening 18 may be formed in the upper portion of the transparent sphere 12a or the upper and lower portions 12a and 12b of the transparent sphere, and may be formed of a transparent material. doors may additionally be attached.

According to the inventors' implementation, it is possible to fully operate by forming one opening each having a size enough to hold an adult's hand in the vicinity of the hemisphere's equator, and in addition, openings having various sizes can be varied as necessary. Of course it can be placed in position.

The opening is one of important features of the present invention, and unlike other conventional celestial spheres which can only be viewed from the outside, it is an essential component for allowing the auxiliary parts to be manipulated as needed. In understanding the coordinates and the like of the celestial body using the present invention, the opening is usefully used.

In the illustrated embodiment, the transparent spheres 12a and 12b are half-assembled and the flanges 14 and 16 are formed at the front end thereof, but this assembling structure and method is only one embodiment. Therefore, it will be easily understood by those skilled in the art that there may be a similar structure performing the same function.

On the other hand, the support rod 6 for supporting the body of the celestial sphere including the transparent spheres 12a, 12b is a rod shape extending in the longitudinal direction, one end of which is the lower pole point of the transparent spheres 12a, 12b. Through and fixed to the position of the lower apex (13b) of the rim sphere 8, the other end penetrates the upper surface of the support means 2 to the groove-shaped fixing member 4 inside the support means It is fixed. The support rod serves as the center of rotation of the transparent sphere while supporting the entire celestial sphere and at the same time fixing the rim sphere 8.

The transparent sphere is larger in diameter than the diameter of the rim sphere and should surround the entire rim sphere as shown. In addition, the transparent sphere should be spaced apart from the rim sphere by a predetermined interval corresponding to the diameter difference for free rotation thereof, while maintaining the separation 19 and simultaneously supporting the entire transparent sphere in a predetermined portion of the support rod. The protrusion 17 protrudes laterally. The chamber is an enlarged view of the lower end of FIG. 2, where, for example, a male screw 6 having a threaded groove on the side is used as the support rod, and the transverse protrusion is a female screw 17 using a corresponding female screw 17. The case where the transparent sphere 12a is supported on the upper surface of the) is shown. As another embodiment thereof, for example, in order to more easily rotate the transparent sphere, a rotary groove having a ball bearing on the surface or a transverse protrusion formed integrally with the support rod is formed in the transparent sphere. It is also possible to insert in the form. Those skilled in the art can easily think of various similar structures.

When the user rotates the transparent sphere in the above structure, the transparent sphere rotates but the rim sphere and the disc member therein do not rotate. Therefore, assuming that the observer is located at the center of the disk member that plays the role of horizon, looking up the rotation of the transparent sphere at that position is similar to seeing the circumference of the celestial body when the observer on the horizon observes the heavenly body. The same thing. The present invention is to use the simulation function effectively to allow users to easily imagine and understand the motion of the celestial body.

In order to prevent the support rod from interfering with the rotation of the transparent sphere, the through portion of the transparent sphere through which the support rod passes is configured such that its diameter is slightly larger than the diameter of the support rod.

Second embodiment

As another embodiment of the present invention, as shown in Figures 3 and 4, a pair of support brackets (40, 42) fixed to the upper surface of the support means (2) in an upright position correspondingly; It consists of an arc-shaped sliding member 44 passing through the long holes (H1, H2) bored at the ends of the pair of support brackets (40, 42), the upper and lower ends of the sliding member 44 While the pair of support rods 6a and 6b are coupled, the ends of the pair of support rods 6a and 6b penetrate the upper and lower pole positions of the transparent sphere, so that the vertices 13a and 13b of the inner rim spheres The celestial body which is coupled to the field is provided.

This embodiment, in addition to the features of the first embodiment, the sliding member 44 penetrating through the pair of support brackets (40, 42) can move freely, so that the celestial sphere can be more inclined One feature is this.

The disk member that performs the horizontal plane function varies according to the region that observes the celestial body, so the position of the disc member changes every time the observation point is changed. When the disc member is inclined, the user is based on the inclined horizontal plane. There is room for confusion because you have to imagine and understand celestial motion. Therefore, by using the present embodiment, when the observation point changes, the inner disc member can tilt the celestial sphere while keeping the horizontal state from the user's point of view, thus imagining the motion of the celestial body more easily without the aforementioned difficulty. You can feel it intuitively.

In FIG. 4, the inner circle shows the mechanical configuration of both poles in detail. The transverse protrusion 17 is configured only at the lower support rod, but may be configured only at the upper end or the transverse protrusion at both extremes.

Third embodiment

FIG. 5 shows another embodiment of the present invention, in which the support brackets 40 'and 42' have the same height and have no step.

Fourth embodiment

FIG. 6 shows a case in which a gear, a motor, and the like are provided in addition to the structure of the above-described second or third embodiment so as to tilt and rotate the celestial sphere by electric.

That is, the rack gear 43 is formed along the edge of the sliding member 44 ', and the lean means 46 of the celestial sphere in which the first pinion gear 45 engaged with the rack gear is coaxially coupled to the supporting means ( 2) is fixed. Therefore, when the first pinion gear 45 coupled to the tilting means 46 of the celestial sphere rotates, the rack gear 43 and the sliding member 44 'engaged with the pinion gear move forward and backward. By rotating the tilting means of the celestial sphere it is possible to tilt the celestial sphere precisely by the desired amount. An electric motor (not shown) may be used as the tilting means of the celestial sphere, and in this case, the first pinion gear is rotated by the rotation of the motor.

In order to automatically rotate the transparent sphere, a cylindrical gear member 47 is fixedly coupled to one of the poles of the transparent sphere, and the second pinion gear 48 is engaged with the cylindrical gear 47. ) May be attached. In addition, when the rotation means 49 of the celestial sphere, which is coaxially coupled with the second pinion gear, is fixed to the sliding member 44 ', the cylindrical gear 47 and the transparent sphere fixed thereto are rotated by the rotation means 49 of the celestial sphere. 12a and 12b can be rotated.

The two gear means may be used either alone or both at the same time, and may further include a gearbox (not shown) or the like for adjusting the rotational speed when the electric motor is used as the power. Of course, both means can be used manually without a motor.

Fifth Embodiment

7 is a view showing another embodiment of the present invention. The embodiment shown in FIG. 7 relates to a celestial sphere configured to mount a vertical protractor therein to allow more accurate vertical angle measurement, which may be particularly useful for measuring various coordinates of a celestial body described below.

To explain the configuration, first, one end of the protractor support 71 is connected to one of the two vertices of the rim sphere so as to be rotatable in the horizontal direction. In the figure, the protractor support 71 is connected to a portion corresponding to the north pole of the rim sphere, but may be connected to the south pole side. In addition, the other end of the protractor support is located at the point 70 at which the angles of the protractor arms 72a, 72b are connected, the reference point for measuring the angle, ie the inner center point of the rim sphere.

The protractor arm is connected to the protractor arm so as to be rotatable in the vertical direction. In the drawing, two protractor arms 72a and 72b are coupled, but if one uses the protractor support 71 as a reference point, all the necessary protractor arms are needed. Measurement is possible.

In addition, when the tip of the protractor arm indicates the position of a particular object, a substantial protractor must be attached to measure the angle quantitatively. In the drawing, a semi-circular protractor 73 is attached along the protractor support, and the center thereof Is arranged substantially coincident with the end of the protractor support, ie the center of rotation 70 of the protractor arm. It is not necessary to use a semi-circular protractor, and may be used by attaching various protractors that perform similar functions as necessary. In addition, when the protractor support 71 is connected to the North Pole of the celestial sphere as shown, for example, the protractor arm must descend to the lower portion of the disc member 10 in order to measure a specific position below the celestial equator. To form a hole 74. The example shown is a U-shaped hole, but since it is determined by the length of the protractor arm, the measuring method and the degree of rotation, a V-shaped or the like is possible, and various shapes such as the open end of the hole 74 'are blocked or blocked. It is possible.

One of the biggest effects common to the embodiments of the celestial sphere of the present invention described above is that it is easy to understand the visual effect on the three-dimensional motion of a complex celestial body that cannot be directly shown or explained in the conventional celestial sphere. Is that. Hereinafter, the method of describing the movement of the celestial body by using the first embodiment of the above-described embodiments of the present invention has been exemplarily described, but the second to fifth embodiments may also be used in the same description method. It is also possible to explain more celestial motions not described here.

Just as latitude and longitude represent the position on Earth, the stars in the sky can also be coordinated to represent their position, which is celestial coordinates. These include horizontal coordinates, the observer's center, equatorial coordinates, and the ecliptic coordinates.

1) How to measure the horizontal coordinate

It is a coordinate system that indicates the position of the celestial body in azimuth and elevation with respect to the horizon where the observer stands and the north point on the horizon.

In Fig. 8, the inclination of the disc member in the celestial sphere is adjusted according to the latitude to be observed, and a puppet that simulates the observer himself is set at the center thereof, and then the ceiling and the bottom are displayed, and the meridian and the orientation are determined. Draw a vertical sphere, which is a member passing through the star X, the ceiling and the ceiling, on a transparent sphere. When the point of meeting with the horizon is B, the angle measured from the north point to the point B from the north point to the point B is measured at the azimuth (A) and the point B. The angle measured to star X along the vertical plane through X is the altitude (h). That is, the coordinates (A, h) representing the position of the celestial body in the azimuth angle (A) and the altitude (h) are horizontal coordinates.

In addition, when rotating the celestial sphere of the present invention in the opposite direction to the earth's rotation (east-to-west), which indicates the circumferential movement of the celestial body as described above, the degree of change in azimuth and altitude depending on the observation time, Also, depending on the position of the observer, the ceilings, ceilings, horizons, and north poles, which are the reference points, change, and thus the azimuth and elevation change can be seen.

2) Equatorial coordinate measuring method

The equatorial coordinates are coordinates representing the positions (α, δ) of the celestial body in the right ascension α and the declination δ using the celestial equator and the vernal equinox centered on the earth.

In Fig. 9, the disc member in the celestial sphere of the present invention is aligned with the equator of the celestial sphere and the position of the vernal equinox meeting the ecliptic is confirmed. Assuming that X is a random point on the surface of the sphere, a time zone that is a member of the celestial north pole, and a celestial south pole, and B is the point where this time zone meets the celestial equator, the angle measured from vernal equinox to point B counterclockwise is right (α) and follow the time zone at point B The angle measured to star X becomes the declination (δ).

One of the things that is not well understood by learners is that the equator coordinates do not change with the observation time. Despite the diurnal motion of, the vernal equinox is also rotated with the celestial body X, so it is easy to see that the coordinates are constant regardless of the observation time. Also, since the vernal equinox and the celestial equator are independent of the observer's position, the coordinates are constant. It is easy to measure the coordinates of the celestial body by installing the meridians and time zones that do not exist in the existing celestial spheres, as well as the built-in disc members corresponding to the celestial horizon or the equator plane. This is because there is an opening that can be. In addition, there are zodiacal coordinates, galactic coordinates, etc. as coordinate systems indicating the position of the heavenly bodies.

3) at starburst

Starburst is the time when the vernal equinox acts as a clock hand, and the angle formed by the time zone passing through the vernal equinox west from the meridian is the time angle of the equinox.

In the case of using the star (X) in FIG. 10, the sum of the right ascension (α) and the time angle (t) of the star is the star time, and the right ascension time of the southern star (X ') is the same as the star time.

Starburst = time angle of the vernal equinox (T)

= Right ascension of star (α) + time angle of star (t)

Right ascension of the southern star (T)

These matters are quite complex in the Earth Science textbook, but the present invention can be easily visually understood. That is, after adjusting the horizon of the disc member in the celestial sphere of the present invention according to the latitude of the observer, after determining the meridian and confirming the vernal equinox, the vernal equinox is turned clockwise (east-to-west) opposite to the rotation of the earth. The moment passing through is called 0h, and the time angle of the vernal equinox measured from the meridian to the west is measured from 0h to 24h.

Thus, unlike the conventional celestial sphere, in the celestial sphere of the present invention, there is a disc member to replace the horizon, and since the meridian which is a reference of the time angle can be set clearly, the vernal movement and the time angle formed by the meridian are checked directly. Can be. In addition, using the celestial sphere of the present invention in a similar manner can easily understand the solar poems used in our daily life.

4) Observation time according to moon phase

The moon orbits about 13 ° daily from west to east around the Earth, so the moon rises about 50 minutes every day. The principle of this phenomenon can be easily seen through the simulation using the celestial sphere of the present invention.

The disk member in the celestial sphere of the present invention is aligned with the horizon of the observer's latitude, and then the Earth's orbit is created by modeling the moon's orbit around the earth and the sun's position at a point outside. If the line connecting the earth and the sun is coincided with the ecliptic plane, the orbit of the moon coincides with the white plane. Since the position of the sun is constantly changing due to the orbit of the earth, the position of the sun on the day of observation should be adjusted to the ecliptic phase. Observing the moon Assuming, the line connecting the earth and the sun should point to the base point.

Then, the position of the moon appearing on the celestial sphere is determined by After marking the transparent sphere, rotate the transparent sphere clockwise (east to west) opposite the Earth's rotation to visually see the moon's rising and falling time. The ecliptic and baekdo have an angle of 5 ° 9 ', and if you ignore this angle and simply make the lunar orbit coincide with the ecliptic plane, you will not have any trouble understanding the moon's observation time and its principle.

Using the celestial sphere of the present invention, since the elements on the motion of the celestial body are displayed on the transparent sphere and then rotated, the observation on the horizon can be represented schematically and visually, so that the user can intuitively understand the celestial movement, It can be expected to maximize the learning effect.

In addition, the interesting celestial model including the user himself can be used instead of the existing complicated explanations, and thus, the interesting effect on learning is also expected.

When using the celestial sphere of the present invention, in addition to the above-described measurement method, the phenomenon of main polarity, appearance, total stark occurs, calculation of each declination range, the change of sunshine time according to the season, and the change of the south middle altitude of the sun. The reason why inward Mercury and Venus are only observed in early evening and early morning. Observation time of extraterrestrials, and the circumference of the celestial body according to latitude can be easily explained and understood. For reference, the present inventors have researched and developed the present invention as a teaching aid for about 27 years as a high school earth science teacher, which is an urgent necessity by experience in class.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many different and obvious modifications are possible without departing from the scope of the invention from this description. Accordingly, the scope of the invention should be construed by the utility model claims described to include many such variations.
