In a die which has a regular polyhedron form and which can be opened into a continuous polygonal form on a plane, boundary areas (Rb) between planes (11 through 16) on the inner side of the regular polyhedron have inclination angles determined according to the regular polyhedron. In addition, engaging portions (21a, 21b, 24a, 24b, 25a, 25b, 26a, 26b) not exceeding the respective boundary areas (Rb) are placed on the boundary areas (Rb) of predetermined planes (11 through 16). Such a die is formed by injecting plastic resin within a mold (31, 32) according to the form of the opened die. This realizes a three-dimensional die capable of being opened onto a two-dimensional plane, which has only been fictionally conceived, and further provides a manufacturing method thereof.
A die which is structured by a polyhedron having multiple planes (11 through 16) of a similar shape and which is opened into a continuous polygonal area on a plane, wherein, in the assembled state of said polyhedron, said die has outer planes (11o through 16o) positioned on the outer side and inner planes (11i through 16i) positioned on the inner side, and has boundary areas (Rb) having a predetermined inclination angle at boundaries of said polygonal area of said inner side, while boundary areas (Rb) of predetermined planes of said opened polygonal area have engaging portions (21a, 21b, 24a, 24b, 25a, 25b, 26a, 26b) of a size not exceeding each boundary area (Rb).
A die which has a hexahedron having six planes (11 through 16) of a similar square shape and which can be opened into a continuous polygonal area on a plane, wherein one predetermined plane making up said hexahedron is provided with an opening mechanism (41, 42, 43) whereby said die can be opened into a planar form with a single touch.
A mold (31, 32) for manufacturing a die which is configured of a polyhedron having multiple planes (11 through 16) of similar shape and which can be opened into a continuous polygonal area on a plane, said mold having the form of said opened polyhedron and comprising a portion equivalent to said opened polyhedron having a predetermined spacing in the thickness direction, and portions equivalent to boundaries (Rb) of said polyhedron having spacing narrower than said predetermined spacing.
A method for manufacturing a die which is configured of a polyhedron having multiple planes (11 through 16) of a similar shape and which can be opened into a continuous polygonal area on a plane, wherein a mold (31, 32) is prepared, said mold (31, 32) having the form of said opened polyhedron and comprising a portion equivalent to said opened polyhedron having a predetermined spacing in the thickness direction, and portions equivalent to boundaries (Rb) of said polyhedron having spacing narrower than said predetermined spacing, and wherein forming is performed by injecting a predetermined resin into said mold (31, 32), thereby obtaining said die.
A die which can be opened in a polygonal configuration on a flat surface, which can be assembled three-dimensionally, and which is assembled by a plurality of planes, wherein:
