Description

  The present invention relates to a three-dimensional structure that can be easily produced by combining a plurality of paper members, and a globe and a planetary globe using the same.

  In general, a globe is manufactured by pasting a plurality of partial maps obtained by dividing a world map onto the surface of a sphere.

When forming a sphere, a main horizontal paper member, a sub horizontal paper member provided in the vertical direction of the main horizontal paper member, and a plurality of vertical papers connected to the main horizontal paper member and the sub horizontal paper member Member. The main horizontal paper member is disposed substantially at the center in the vertical direction of the three-dimensional structure to be manufactured, and constitutes the longest horizontal portion of the three-dimensional structure, and may be polygonal or circular Good. When formed in a polygonal shape, corners are formed in the horizontal direction of the three-dimensional structure, and when formed in a circular shape, there are no corners in the horizontal direction of the three-dimensional structure and formed in an arc shape. It becomes. When forming into a polygonal shape, it is necessary to make it at least a quadrangle, and as the number of corners increases, the three-dimensional structure can be made closer to a sphere. Further, one main sheet member may be disposed at the center in the vertical direction of the three-dimensional structure, or two sheets may be disposed above and below the center in the vertical direction.

  The auxiliary horizontal paper member is disposed between the upper and lower ends of the three-dimensional structure in the vertical direction, and is formed in a similar shape to the main horizontal paper member. That is, when the main horizontal paper member is formed in a circular shape, it is formed in a circular shape, and when it is formed in an octagonal shape, it is formed in an octagonal shape. One or more sub-sheet members are required in the vertical direction, and by increasing the number, the vertical corners of the three-dimensional structure can be made smooth, so that the shape can be made close to a sphere.

  Cuts are formed in the radial direction in the main horizontal paper member and the sub horizontal paper member. This incision engages with the incision formed in the vertical paper member to integrally connect and fix the main horizontal paper member, the sub horizontal paper member and the vertical paper member, and engages the incision of the vertical paper member. At this time, it is necessary that the inner end side of the vertical paper member substantially coincides with the axis of the three-dimensional structure. The length of the cut is not particularly limited, but may be a half of the radius (the cut of the vertical paper member is also a half of the radius of the main horizontal paper member and the sub horizontal paper member), or 1 / of the radius. 3 (the cut of the vertical paper member is 2/3 of the radius of the main horizontal paper member and the auxiliary horizontal paper member), and the length of 2/3 of the radius (the cut of the vertical paper member is the main 1/3 of the radius of the horizontal paper member and the auxiliary horizontal paper member). Moreover, it is preferable that the opening part of a notch is made into a taper-shaped opening, By making it a taper-shaped opening in this way, when engaging the notch of a vertical paper member, it can insert easily.

  The vertical paper member engages with the main horizontal paper member and the secondary horizontal paper member to connect and fix the main horizontal paper member and the secondary horizontal paper member, and the inner end side substantially coincides with the central axis of the three-dimensional structure. The outer end side is formed in a polygonal shape or a semicircular shape. When the outer side edge is formed in a polygonal shape, it is formed corresponding to the number of main horizontal paper members and sub horizontal paper members. For example, one main horizontal paper member and two sub horizontal paper members (the upper and lower totals) In the case of (number), it is formed of four sides having three corners, and in the case of one main horizontal paper member and four sub-horizontal paper members (total number of top and bottom), it has five corners. It is formed to have 6 sides.

  The main horizontal paper member, the sub horizontal paper member, the vertical paper member, and the cover member are not particularly limited as long as they are bendable materials such as cardboard and plastic sheets. Since the cover member is exposed on the surface of the three-dimensional structure, a pattern, a color, or the like is applied according to a desired purpose.

  The three-dimensional structure as described above can easily produce a polyhedron simply by connecting and assembling a horizontal paper member, a vertical paper member and a cover member, and all the members are flat before connecting and assembling. Therefore, the space for storage and the like can be reduced. Such a three-dimensional structure can be used for various uses such as interiors, and can be used for, for example, a globe, a planetary globe, a calendar, and the like. When used for the globe, it can be manufactured by applying a predetermined world map to the cover member, and the vertical paper member is formed so that the outer edge is polygonal, and the outer edge and the inner edge at the upper and lower ends It is preferable that the angle with the side is adjusted (approximately 67 degrees) so that the inner edge is at an angle of approximately 23 degrees with respect to the vertical direction when the vertical paper member at the lower end is placed on the horizontal plane. With such a configuration, the axis of the three-dimensional structure (substantially coincident with the inner edge of the vertical paper member) can be matched with the inclination of the ground axis.
