Abstract

PURPOSE: To easily install an astronomic display device at general household and to use the device as an illuminator by providing a constellation disk, on which constellation graphics are drawn in relation with a large number of small through holes, so as to be rotated and vertically moved and providing a light source at a prescribed position. CONSTITUTION: Small through holes 15 are pierced at positions corresponding to celestial bodies, a constellation disk 14 in which graphics 16 or pictures showing the constellations are drawn on its lower face is set at a move-up position, when turning on a light source 19 fitted lower than the move-up position of the star chart 14 and higher than the move-down position, the constellations can be observed from the downside, and the inside of a room is indirectly illuminated by the reflected light of the star chart 14. Then, when turning a motor 12, the start chart 14 is gradually rotated. Next, when a motor-driven take-up machine 11 is driven and the star chart 14 is moved down, the light of the light source 19 is irregularly reflected by a canopy 3, the small holes 15.... can be observed from the downside just like the celestial sphere shining in the night sky and when the motor 12 is driven, the kinetic conditions of the celestial sphere can be observed. Thus, this device is made extremely convenient for teaching and can be used also as decoration and illumination.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device installed on the ceiling of a room for observing the positions and movements of celestial bodies.

[Conventional technology]

Conventionally, a simple constellation board made of paper or the like has existed as a teaching tool for displaying constellations. Also.

A planetarium existed as a high-performance device that was a big loss.

[Problem that the invention seeks to solve]

Among these, the constellation board used as a teaching tool was placed on a desk or the like and observed from above, so it was far from the experience of looking up at the sky and seeing the celestial bodies. In addition, the planetarium
In addition to requiring a darkroom with a dedicated dome, it was extremely expensive, making it difficult to use in general households.

The present invention aims to provide a celestial body display device that can be easily installed in the living room of a general household and also serves as a lighting device.

[Means for solving problems]

The celestial body display device of the present invention is made of a non-transparent plate material and has a large number of small holes corresponding to the celestial bodies.

The lower surface has a constellation disk on which constellation figures related to these small holes are drawn. It is desirable that the diameter of the above-mentioned small through-holes varies depending on the brightness of the celestial body (G).

The constellation board is rotatably and movably installed below the canopy whose lower surface reflects light diffusely. It is desirable that the rotation and elevation of the constellation board be electrically controlled and remotely controlled, but the rotation and elevation may also be performed manually.

There is a light source like a ball.

[For production]

When the constellation disk is in the lowered position, the source of the light source diffusely reflected from the lower surface of the canopy can be seen through each small hole in the star disk, so each of these small holes looks like a shining celestial body in the night sky. . By gradually rotating the constellation disk, you can observe from below how the celestial bodies rotate over time.

Next, when the constellation disk is in the raised position, the light from the light source illuminates the bottom surface of the constellation disk, so you can observe the small through holes in the constellation disk as sunspots, and at the same time observe the constellation shapes drawn on them. can do. In this case as well, by gradually rotating the constellation disk, it is possible to observe from below how the celestial bodies and constellations rotate over time.

In addition, when the constellation board is in the raised position, the light from the light source is reflected by the constellation board and indirectly illuminates the room, so it can also be used as a lighting device.

〔Example〕

In FIGS. 1 and 2, &l is an outer box consisting of a peripheral wall 2, a canopy 3 closing the upper end of the first peripheral wall 2, and an annular mounting seat 4 continuous to the lower end of the first peripheral wall 2.

The lower surface of the canopy 3 is coated with, for example, a light gray paint that diffusely reflects light.

Vertical guide rods 5 are supported at opposing positions between the canopy 3 and the mounting seat 4, and each guide rod 5 has a sleeve 6.
is fitted in such a way that it can be raised and lowered. A beam 7 is passed between the two sleeves 6, and the beam 7 is suspended by wire ropes 8, 8 at appropriate places.The other end of the wire ropes 8, 8 is connected to pulleys 9, 10.
The film is then wound up by an electric winding machine 11.

A low-speed electric motor 12 is attached to the center of the beam 7, and the lower end of a rotating shaft 13 that hangs down from the motor supports the center of the constellation board 14. The constellation board 14 is a disc made of an opaque plate-like material, and has small through holes 15, 15 and 15 at positions corresponding to the celestial bodies.
... is perforated, and the bottom surface has figures 16, 16, ... or pictures showing constellations as shown in Fig. 3. A transparent plate 17 is stacked below the constellation board 14 at a slight interval, and the transparent plate 17 is supported by the sleeve 6. On the transparent plate 17, a field of view display 18 shown in FIG. 3, lines and indicators indicating directions, etc. are drawn.

Lower than the raised position of the constellation board 14 shown in FIG.

A light source 19 is attached to the peripheral wall 2 at a position higher than the lowered position of the constellation board 14 shown in FIG.

The above-mentioned device can be installed by drilling a window hole 21 in the ceiling 20 of a room, fixing the mounting seat of the outer box 1 on the edge of the hole, and attaching a frosted decorative edge 22 to the edge of the hole.

The decorative edge 22 has an upright edge 23 so that the light from the light source 19 does not directly enter the eye.

In the above-mentioned apparatus, when the constellation board 14 is placed in the raised position as shown in FIG. 1 and the light source 19 is turned on.

The constellations can be observed from below, and the room is indirectly illuminated by the light reflected from the constellation board 14. When the electric motor 12 is rotated, the constellation board 14 is gradually rotated.

Next, when the electric winder 11 is driven and the constellation board 14 is lowered to the position shown in FIG. 15...
can be observed like a celestial body shining in the night sky, and by driving the electric motor 12, the movement of the celestial body can be observed.

Note that instead of the transparent plate 17, a light-shielding plate having a window hole of the same shape as the visual field display 18 may be installed above the constellation board 14 in a non-rotatable manner, and in that case, it can be observed according to the season or time. Only astronomical objects are displayed.

〔Effect of the invention〕

As described above, according to the present invention, celestial bodies can be displayed in a realistic manner with a relatively simple structure, and when the constellation board is raised, the constellations are displayed.
It is extremely convenient for teaching.

It can also serve as interior decoration and lighting.
