Abstract

To provide an intellectual training toy which can suppress noise and improve safety, and which has a significant effect on developing children's intellect, maintaining or recovering the mental and physical functions of the elderly, and other purposes. An intellectual training toy whose material is a soft elastic material comprises a triangular annular member ( 1 ), wherein a user can turn an inside surface and an outside surface of the annular member ( 1 ) inside out, and the shape of the annular member ( 1 ) changes when the user turns the inside surface and the outside surface of the annular member ( 1 ) inside out. Since the intellectual training toy is made of a soft and pliable material, noise can be suppressed and safety can be improved. With this intellectual training toy, since the shape of the annular member ( 1 ) changes when the user turns the inside surface and the outside surface of the annular member ( 1 ) inside out, there is a significant effect on developing children's intellect, maintaining or recovering the mental and physical functions of the elderly, and the like.

1 . An intellectual training toy made of a soft and pliable material, comprising:
 a polygonal annular member; wherein   a user can turn an inside surface and an outside surface of the annular member inside out, and the shape of the annular member changes when the user turns the inside surface and the outside surface of the annular member inside out.   
     
     
         2 . An intellectual training toy made of a soft and pliable material, comprising:
 an elliptical or circular annular member, wherein   the thickness of the annular member, which is a distance between an inside surface and an outside surface of the annular member, is not uniform; and   a user can turn an inside surface and an outside surface of the annular member inside out, and the shape of the annular member changes when the user turns the inside surface and the outside surface of the annular member inside out.
