  • the lid portion 42 in this embodiment is configured so that the folded portion 41b and the lid portion 42 are substantially flush with each other when the lid portion 42 is attached to the main body portion 41. In this way, in this embodiment, the folded portion 41b and the lid portion 42 form the bottom surface Ue of the second portions W1 to W12.

  • the lid 42 is formed with a columnar portion 42a that fits into the hollow portion 41e of the cylindrical portion 41d. Therefore, in this embodiment, by fitting the columnar portion 42a into the cylindrical portion 41d, the opening 41a is closed, and the triangular pyramid-shaped second portions W1 to W12 are formed.
  • the cross section of the hollow portion 41e is hexagonal, and the cross section of the columnar portion 42a is circular. In this way, by making the cross-sectional shapes of the hollow portion 41e and the columnar portion 42a different, the columnar portion 42a can be easily inserted into the hollow portion 41e.
  • a stopper portion 41f is formed inside the main body portion 41 near the end on the bottom surface W1d side of the triangular pyramid shape.
  • the stopper portion 41f is formed in a ring shape along the entire end near the end on the bottom surface Ue side of the triangular pyramid shape.
  • the twelve second sections W1 to W12 can be manufactured, for example, by preparing male and female molds for the main body 41 and the lid 42, respectively, and then injecting thermoplastic resin into each mold using an injection molding machine or the like.
  • the toy 1 of this embodiment is equipped with a connecting member S, and each of the polyhedrons U1 to U12 is connected to other polyhedrons via the connecting member S.
  • the polyhedrons are indirectly connected to each other.
  • FIG 10 is a plan view of the connecting member.
  • the connecting member S of this embodiment is composed of a single sheet having an annular shape. More specifically, the connecting member S of this embodiment has 12 quadrangular portions SV (SV1 to SV12) and 12 triangular portions SW (SW1 to SW12) connected to each of the quadrangular portions SV.
  • Each quadrangular portion SV has a first connection portion SC1 that connects the quadrangular portions SV to each other, and a second connection portion SC2 that connects the quadrangular portion SV to the triangular portion SW.
  • the 12 quadrangular portions SV (SV1 to SV12), the 12 triangular portions SW (SW1 to SW12), the first connection portion SC1, and the second connection portion SC2 are integrally formed.
  • the 12 quadrangular portions SV1 to SV12 have the same shape.
  • the 12 triangular portions SW1 to SW12 have the same shape.
  • the multiple first connection portions SC1 have the same shape.
  • the multiple second connection portions SC2 have the same shape.
  • the connecting member S is configured so that the 12 quadrilateral portions SV (SV1-SV12) correspond to the first portions V1-V12 of the 12 triangular prism-shaped polyhedrons U1-U12, respectively. Therefore, the quadrilateral portions SV1, SV6, SV7, and SV12 corresponding to the first portions V1, V6, V7, and V12 of the four polyhedrons U1, U6, U7, and U12 have the first connection portion SC1 on the side opposite the side on which the second connection portion SC2 is provided.
  • the quadrilateral portions SV2-SV5 and SV8-SV11 corresponding to the first portions V2-V5 and V8-V11 of the eight polyhedrons U2-U5 and U8-U11 do not have the first connection portion SC1 on the side opposite the side on which the second connection portion SC2 is provided.
  • the longitudinal dimensions of the first connection portion SC1 and the second connection portion SC2 are substantially the same as the longitudinal dimensions of the recesses 31c and 41c.
  • a through hole H is formed in each of the first connection portion SC1 and the second connection portion SC2.
  • the connecting member 41 is made of polystyrene.
  • a sheet-like connecting member 41 can be manufactured, for example, by punching a polystyrene sheet into the shape of the connecting member.
  • the cylindrical portion 31d of the main body portion 31 and the cylindrical portion 41d of the main body portion 41 are inserted into the through-hole H of the connecting member S.
  • the columnar portion 32a of the lid portion 32 is fitted into the hollow portion 31e of the cylindrical portion 31d
  • the columnar portion 42a of the lid portion 42 is fitted into the hollow portion 41e of the cylindrical portion 41d, so that the connecting member S is sandwiched between the lid portion 32 and the recess 31c, and between the lid portion 42 and the recess 41c, forming the first polyhedron.
  • the polyhedrons U1 to U12 are indirectly connected to other polyhedrons via connecting members S. Therefore, because the two connected polyhedrons are connected with a gap between them, when one polyhedron is rotated relative to the other, the other polyhedron comes into contact with the first polyhedron, preventing the first polyhedron from interfering with the rotation or damaging the polyhedron during the rotation.
  • the width dimension of the connecting member S at the portion connecting the polyhedrons is substantially the same as the longitudinal dimension of recesses 31c and 41c, so the two connected polyhedrons can be displaced so that their bases twist relative to each other. This allows for smooth rotation and a wide range of movement for the connected polyhedrons. This allows for a wide variety of deformations.
  • the toy 1 of this embodiment can be transformed from a state in which the quadrangular faces of the quadrangular pyramid shape of the first part of each polyhedron shown in Figure 1 are placed on the same plane, into various shapes, for example, as shown in Figures 13 to 38.

Abstract

L'invention concerne un jouet polyédrique qui est riche en configurations de jeu, présente des changements morphologiques imprévisibles, et permet ainsi d'améliorer l'aspect casse-tête du jouet. L'invention concerne un jouet polyédrique constitué de 12 polyèdres en forme de prisme triangulaire. Selon l'invention, chacun des polyèdres est constitué d'une première partie et d'une seconde partie ; la première partie possède une forme de pyramide quadrangulaire comprenant une surface latérale d'une forme de prisme triangulaire et l'une des bases de la forme de prisme triangulaire ; la seconde partie possède une forme de pyramide triangulaire comprenant l'autre des bases de la forme de prisme triangulaire ; dans la première partie, l'arête côté autre base de la forme de prisme triangulaire comprise dans l'une surface latérale de la forme de prisme triangulaire est relié à l'arête de l'autre base comprise dans la seconde partie ; et dans une vue en plan dans laquelle des faces quadrilatérales des formes de pyramide quadrangulaire des premières parties des polyèdres sont placées sur le même plan, les polyèdres possèdent chacun une face quadrilatérale de la forme de pyramide quadrangulaire de la première partie reliée à des faces quadrilatérales des formes de pyramide quadrangulaire des premières parties de deux autres polyèdres.
