Document Type and Number:
Japanese Patent JP2015188742
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a paper-made joining structure for a doll joint, capable of making a doll joint portion strong, holding a doll stably in a standing state for a long time, and also constituting the doll in an integral manner.SOLUTION: A joining structure for a doll joint comprises an outer cylinder block having a shape of a regular n-polygon (here, n is an even number of 6 or more) and an inner cylinder block having the same shape and a size that slidably fits in a cavity of the outer cylinder block. One end of the inner cylinder block is penetrated through the outer cylinder block from one side surface side of the outer cylinder block toward the other side surface which is plane symmetry to the one side surface, and is protruded out on the other side surface side to be fixed. Further, at least one structure is selected as the joining structure of the doll joint from the followings: a first structure in which a diagonal line passing through a center of the regular n-polygon of the inner cylinder block is aligned with a mountain folding line of the outer cylinder block when penetrating; a second structure in which the diagonal line of the inner cylinder block is aligned with an intermediate line for longitudinally dividing a side wall of the outer cylinder block in half, when penetrating; a third structure in which a center line for symmetrically dividing the regular n-polygon of the inner cylinder block in half is aligned with the mountain fold line of the outer cylinder block when penetrating; and a fourth structure in which the center line of the inner cylinder block is aligned with the intermediate line of the outer cylinder block when penetrating.
