Abstract: A construction toy set includes a number of pieces of different shapes and colors which are configured to allow a user to construct a desired object or model by connecting selected pieces to one another. One of the pieces is a first joint piece constructed to connect two other pieces of the set for relative rotational movement about an axis of the piece. The joint piece has a body formed of two parts that are joined to one another for relative rotation about the joint piece axis, and each part is configured to connect to another piece of the set. The set also includes a second joint piece constructed to connect two other pieces of the set for relative rotational movement about two orthogonal axes of the piece. The bodies of the joint pieces emit a pleasant click sound when the parts of the bodies are turned by the user.

Abstract: A construction toy set that stimulates young children to plan and construct objects with which they can play or interact when finished. The set includes pieces with joints that allow the child to build an object having parts that turn or rotate, allowing him or her to play actively with the object when fully assembled. Many of the pieces are relatively large and brightly colored, and have soft textured surfaces that stimulate the child's senses of sight and touch. The rotatable pieces turn in response to a moderate force while emitting a pleasant clicking sound that appeals to the child's sense of hearing. Accordingly, the inventive toy set enhances the child's creativity, imagination, and dexterity by encouraging him or her to plan, assemble, and then interact with a finished object or model. Further, the finished object can be easily disassembled and then reassembled as often as desired by the child.
