Description

[Detailed Description of the Invention] This invention relates to a rolling softball that is mainly used to improve the motor skills of young children.

This idea was created with the aim of providing a softball that is easy for young children to grasp and throw, is soft and non-hazardous when hit, and is ideal for playing indoors, such as when a parent rolls the ball around and has the child throw it back. be.

Hereinafter, this invention will be explained with reference to drawings which are examples.
The inside of the ball is filled with cotton 2 with appropriate elasticity to provide a ball, and the surface of the outer shell is provided with three-dimensional folds 3 for grasping, which are made fluffy by filling an appropriate amount of cotton 2.

The outer cover 1 shown in the drawing is made by cutting 20 outer cover cut cloth pieces 10 into circular shapes with the same diameter on the periphery, each cloth piece 1.
Bent edge 1 of an equilateral triangle whose vertices are inscribed in the periphery of 0
Connect 15 by sewing along lines 1, 11, and 11 to form an equilateral triangle.
A hollow skin 1 in the form of an icosahedron is provided, and a required amount of cotton core 2 such as natural cotton or synthetic fiber cotton is filled in the hollow part to provide appropriate elasticity.
The part surrounded by 1, 11 and the peripheral edge 12 is the pleat piece 1
3, 13, 13, a cotton core 2 is inserted into the corresponding pleat pieces 13, 13, and the peripheral edges 12, 12 are sewn and connected 16 to form a three-dimensional pleat 3 rich in appropriate elasticity. It is what it is.

Note that 14 is a seam allowance. Furthermore, the sewing order of the cut pieces for outer skin is not limited to the above embodiment, and as shown in FIG. It is also possible to provide three-dimensional pleats and provide them on the circumferential surface of the regular polygonal polyhedron.

Since this invented ball is provided as described above, there is no danger in giving it to a child to roll indoors, for example, and it is easy to grasp by hooking one's fingers on the three-dimensional folds on the circumference, and easy to throw. Therefore, it is ideal as a softball for playing with young children.

The cut cloth pieces for constructing the outer skin are not limited to the above embodiments, and any regular polyhedron can be used. Moreover, if printed fabric is used for the piece of cloth, the outer surface can be beautifully decorated.
