Description

[Detailed description of the invention] The present invention relates to a solar system planet movement model that allows the movement of the solar system planets to be observed at a glance.

Traditionally, models such as globes have been used to observe the geography of the Earth and the surface conditions of the Moon, but these models only allow us to understand the surface conditions and rotational conditions of the Earth and the Moon.
It was not possible to observe the mutual movement of the moons or their revolutions with respect to the sun.

Furthermore, although it is possible to roughly understand the arrangement of the planets in the solar system and their rotations and revolutions through text and illustrations, it is not possible to see the whole thing comprehensively at a glance.

Furthermore, although the movement of the planets is a topic that is easy for children to be interested in, there were no teaching materials that would make it easy to understand.

The purpose of the present invention is to solve the above-mentioned problems and provide a model of the movement of the planets in the solar system that allows the movement of the planets in the solar system to be accurately and easily understood.

Embodiments of the present invention will be described based on the drawings.

FIG. 1 is a partially cutaway side view of an embodiment of the present invention, and FIG. 2 is a plan view of the same.

A center shaft S□ is vertically rotatably placed in the center of a horizontal base 1, a sun model 2 is installed at the upper end of the center shaft S1, a bevel gear 3 is installed at the lower end, and a rod 4 is installed through the side of the base 1. A bundle 5 is provided at one end of the rod 4, and a bevel gear 6 that meshes with the bevel gear 3 is provided at the other end.

In this case, it is assumed that the bundle 5 is a manual type, but the rod 4 may be rotated by an electric type.

Next, a horizontal top plate 7. A gear box 9 having a bottom plate 8 is drilled at an appropriate position, and a center shaft S□ is inserted into the through hole (not shown), and the gear box 9 is attached to an arbitrary number of wheels 10.
... and support it on the base 1.

Note that 11 in the figure is a support arm. Next, in the gearbox 9, there are five shafts S2 apart from the central shaft S□. S3.
S4. S6. S6 is rotatably installed vertically, and each #1...
...Gear W1 with a fixed number of teeth each in S6...
- Provide W6 so that they mesh one after another.

Further, even-numbered axes S5 from the central axis S1 are extended onto the top plate 7 of the gearbox 9, and an earth model 12 is provided at the upper end of the extended portion.

In this case, the even-numbered shaft S is selected because the direction of rotation of the shaft is the same as the direction of rotation of the central shaft 1.

This setting is made because the direction of rotation of the Earth and the direction of revolution of the Earth and the Moon are the same as the direction of rotation of the Sun.

The following structures are set in the same way. Next gear box 9
A hollow shaft 13, which is fitted into the extension of the shaft S5, is rotatably hung at a predetermined position on the top plate 7, and a horizontal disc 14 is provided near the upper end of the hollow shaft 13, and a horizontal disc 14 is provided around the periphery of the disc 14 as appropriate. A number of gear teeth 15 are carved, and a moon model 16 is carved on the disc 14.
Place.

Next, extend the shaft S6 onto the top plate 7 of the gearbox 9,
An upper bevel gear 17 is provided at an appropriate position, and the disc 14 is set to be interlocked with the upper bevel gear 17 through attached bevel gears 18 and 19.

In this case upper bevel gear 17. The number of teeth of bevel gear 18 is the same as gears W1...W6, and bevel gear 19
The ratio of the number of gear teeth 15 of the disk 14 and the number of gear teeth 15 of the disk 14 is 1:30.

Note that the bevel gears 18 and 19 do not necessarily need to be used, and the upper bevel gear 17 and the gear teeth 15 of the disc 14 may be directly engaged with each other. The ratio is 1:30.

However, the setting of the upper gear 17 is not limited to the shaft S6, and may be provided on another shaft, in which case the gears may be combined as appropriate in consideration of the rotation direction and rotation speed.

Next, the shaft S is extended below the bottom plate 8 of the gear box 9, and a lower bevel gear 10 is provided at an appropriate position.

Furthermore, a mounting member 2 is vertically installed on the bottom plate 8 of the gearbox 9.
Attach bevel gears 24 and gears 25 that are attached to each other to 3.

The lower bevel gear 20 meshes with the bevel gear 24 and gear 2
5 meshes with gear teeth 27 carved on the top surface of a circular rail 26 laid on the top surface of the base 1.

In this case, the number of teeth of the lower bevel gear 20 and the bevel gear 24 is the same as that of the gears W1...W6, and the ratio of the number of teeth between the gear 25 and the gear teeth 27 of the circular rail 26 is 1:365.

However, the setting of the lower bevel gear 20 is not limited to the shaft S5, but may be provided on another shaft, and in that case, the gears may be appropriately combined in consideration of the rotation direction and rotation speed.

In addition, bevel gear 24. The gear 25 does not necessarily need to be used, and the lower bevel gear 20 and the gear teeth 27 of the circular rail 26 may be directly engaged with each other, and in this case, the ratio of the lower bevel gear 20 and the gear teeth 27 is 1:365.

Further, in this case, in order to move the entire gearbox in the same rotational direction as the shaft S1, the gear teeth 27 must be carved on the outer circumferential side of the circular rail 26.

Alternatively, a belt may be used instead of a gear to interlock the shafts S and S6 from the central shaft S.

In addition, 28 in the figure is a model of another planet.If a support arm is arbitrarily attached to the gearbox 9, and a model of another solar system planet is installed at the tip of the support arm, the state of rotation of these planets with respect to the sun can also be reproduced. It turns out.

As described above, a rotatable central shaft (solar rotation axis) S is vertically installed in the center of the horizontal base 1, the central shaft S1 is inserted into the horizontal board, and the horizontal board is supported by the wheels 10. In addition, a hollow shaft (monthly rotation axis) and an axis (earth revolution axis) are provided on the horizontal substrate, and each axis is in the same direction as the central axis S□ due to the central axis S1, and the axis (earth rotation axis) Hollow shaft for 300 rotations (
The monthly rotation axis) is interlocked to make one rotation, and a shaft is provided at a predetermined position under the horizontal board that is interlocked from the central axis (solar rotation axis) Sl, and a gear is provided at the tip of the shaft. By interlocking, the entire horizontal board is rotated around the axis (Earth revolution axis) 365
Since it is configured to rotate once per rotation, by rotating the central axis (solar rotation axis) Sl, the moon model will rotate around the earth model by l/3 (2) with one rotation of the earth model.
The moon model and the earth model revolve around the sun model 17,361 times.

As mentioned above, according to the present invention, by manually or electrically rotating the central axis, it is possible to determine not only the surface conditions of the Earth and the moon, but also the mutual entrainment of these objects and the state of their revolutions around the sun. Can be observed accurately at a glance,
It is thought that this will be an extremely easy-to-understand teaching material, especially for lower grade children who still lack knowledge and understanding.
