TOY

To provide a toy which can be formed by combining single shaped sheet-shaped members (pieces), in which an assembled three-dimensional object has an irregularity with unified aesthetics over all directions and exhibits high design property, and using the irregularity, pieces can be freely coupled in a vertical direction and a lateral direction.SOLUTION: There is provided a toy comprising: a rectangular foundation surface 102; triangular surfaces 110 each of which is jointed to one/the other of both ends in a short side of the foundation surface 102 through a fold α, and is formed into a rectangular equilateral triangle shape whose short side on the foundation surface 102 is a hypotenuse; and rectangular auxiliary surfaces 120 each of which is jointed to one/the other of two sides forming a right angle of the triangular surface 110, through a fold β. On each of sides facing two sides forming the right angle on the auxiliary surface 120, an engagement protrusion 130 is formed. The foundation surface 102 is formed with an engagement parts 103a having such a shape that four engagement protrusions (of other sheet-shaped members) can be engaged thereto. Six sheet-shaped members formed into a same shape to the sheet-shaped member are assembled for forming a three-dimensional object.SELECTED DRAWING: Figure 8 【課題】単一形状のシート状部材（ピース）を組み合わせて構成でき、更にその組み上げた立体は全方向に渡って統一的な美感を備えた凹凸を有して高い意匠性を誇り、加えて当該凹凸を利用して縦横に自由自在な連結が可能な玩具を提供する。【解決手段】矩形の基礎面１０２と、当該基礎面１０２の短手側両端にそれぞれ折り目αを介して連接し、基礎面１０２の短手辺が斜辺となる直角二等辺三角形状に構成された三角面１１０と、この三角面１１０における直角を構成する二辺にそれぞれ折り目βを介して連接する矩形の補助面１２０と、を備え、この補助面１２０における直角を構成する二辺に対向する辺には、それぞれ係合突起１３０が形成されると共に、基礎面１０２には、（他のシート状部材の）係合突起が４つ係合できる形状の係合部１０３ａが形成されており、これと同一形状のシート状部材を６枚組み合わせて立体とする。【選択図】図８
