JPH0710759U - Wire holding rotating globe - Google Patents

Abstract

(57) [Summary] [Purpose] This proposal is intended to represent a rotating earth without being supported by an axis. Also, because the earth axis can be oscillated horizontally or within a range of approximately 23.5 degrees with respect to the horizontal, the sun will always be in the direction directly above,
It is easy to understand day and night and the season. Because it is box-shaped and stable, it can be used as a tabletop teaching material of a reasonable size. Note that the sphere can have a pattern other than the globe. [Structure] A wire is wound around a groove dug on the equator and attracted, the lower surface of the sphere is held by a plurality of rollers, and the wire has a mechanism for rotating the sphere. Further, the entire mechanism that provides the rotational movement can be swung along a guide centering on the sphere. Rotational motion is given by a motor and speed reducer, and rocking is done by an operating knob. Since the mechanism is hidden under the upper plate of the mechanism box, the sphere is slightly sunk on the upper plate. Make a gap between the inner edge of the upper plate and the surface of the sphere to avoid interference. The surface color of the upper plate should have the image of the night sky. Also, it is desirable to cover the sphere with a transparent box.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a figurine whose main ornamental object is a sphere that rotates on behalf of a globe placed on a table or the like.

[0002]

[Prior art]

 Conventionally, it has been the usual method to hold a rotating sphere represented by a globe by holding the rotating shaft. In addition, the globe is generally a so-called vertical type in which the axis of rotation is inclined 23.5 degrees with respect to the vertical.

[0003]

[Problems to be solved by the device]

 Holding the globe on the axis of rotation impaired the image of the Earth, which was not originally held on the axis of rotation. This proposal is intended to represent a rotating earth that is not supported by an axis. In addition, the globe is generally a so-called vertical type in which the axis of rotation is tilted by 23.5 degrees with respect to the vertical, but in this case the sun is in the horizontal direction and it is difficult to understand whether it is day or night. On the other hand, this proposal can be said to be a horizontal type in which the rotation axis is horizontal or inclined by 23.5 degrees with respect to the horizontal, and the sun is directly above, making it easy to understand whether it is day or night.

[0004]

[Means for Solving the Problems]

 The globe of this proposal basically has a shape in which a sphere is placed on a mechanism box, and a transparent box protects the globe. The earth axis is horizontal or can swing about the sphere within about 23.5 degrees from the horizontal. A wire is wound around a groove dug in the equator of the sphere to draw it, and the lower surface of the sphere is held by multiple rollers to hold the sphere, and the wire has a mechanism that imparts rotational movement to the sphere. In addition, the entire mechanism that imparts rotational movement is swung along a guide centered on a sphere. Rotational motion is given by a motor and speed reducer, and rocking is done by an operation knob that comes out of the mechanism box. The part that pulls the wire, the roller that supports the sphere, and each mechanism are hidden from view because they are hidden under the upper plate of the mechanism box, and the sphere is slightly sunk in the upper plate. Make a gap between the inner edge of the upper plate and the spherical surface so that they do not interfere. The surface color of the upper plate should be the image of the night sky.

【Example】

 FIG. 1 shows an external view of an embodiment of the present invention. In the figure, 1 is a sphere, 2 is a wire on the equator, 3 is a ground axis, 4 is a mechanism box, 5 is a transparent box, 6 is an operation knob for swinging, and 7 is a switch for rotation. The upper plate 8 is an image of the night sky on the surface.

FIG. 2 shows a sectional view perpendicular to the earth axis 3 of FIG. In the figure, reference numeral 2 is a wire that almost surrounds the groove on the equator of the sphere 1. Numeral 9 is a grooved roller for wire that pulls the wire. Reference numeral 11 denotes a wire driving roller, and a wire driving wheel 12 is coaxially provided to which a speed reducer 13 and a motor 14 are connected. Reference numeral 15 is a wire tension roller whose shaft is pressed by a spring 16 to keep the wire tension. Reference numeral 17 is a rotary motion part frame, and swing guide plates 18 are fixed to both sides thereof. The swing guide plate 18 can swing along a guide roller 19 fixed to the mechanism box 4 along a locus for keeping the center of the sphere 1 at a fixed position. Reference numeral 20 denotes a rocking drive wheel, which is connected to the rocking operation knob 6 via a knob wheel 21. The reason for inserting the knob wheel is to make the operating direction of the rocking operation knob and the rocking direction of the ground axis the same. A rack 22 is provided on the rocking guide plate 18 and meshes with the rocking guide plate 18 to rock the rotary motion part frame 17. Reference numeral 23 is an electric cord, 7 is a rotary switch, and 24 is a dry battery.

FIG. 3 shows a sectional view parallel to the ground axis 3 of FIG. A sphere supporting roller 10 is provided on both sides of the grooved roller 9 for wire in the figure, which is coaxial, but supports the sphere. Further, in the figure, the rotary motion part frame 17 swings about 23.5 degrees to the left and right in the figure along with the swing guide plate 18, the guide roller 19 centering on a sphere, the swing drive wheel 20, and the guide idler 25. Can move. In addition, 1 is a sphere, 7 is a rotation switch, 14 is a motor, 21 is a knob wheel, and 24 is a dry battery.

[Effect of device]

 The invention makes it possible to obtain a rotating sphere with no bearings. Also, since the rotation axis can swing around a sphere, if the wires on the equator are inconspicuous, a mysterious mystery can be expressed. If the rotation axis is swung within about 23.5 degrees from the horizontal, the day and night season can be explained and understood correctly, assuming that the direction of the sun is always right above. If the sphere has a pattern other than the globe, it can be made into a moving figurine of reasonable size.
