Abstract

PROBLEM TO BE SOLVED: To provide a ball playground equipment for infants using an irregular rugged and glittering material which is popular with infants. SOLUTION: A styrene plate material is placed in a spherical mold having random irregularities in a heated state, and then air is injected into the styrene plate material and inflated along the mold to make the main body spherical and random on the outer and inner surfaces. After molding into a shape having various irregularities 2, unnecessary protrusions generated in the molding process are scraped off to obtain a translucent hollow spherical body 1.

Description

The invention of the present application relates to a ball-shaped toy for infants.

As a ball-shaped toy for infants, a cloth ball (Patent Document 1) that is soft and safe, and has fun in use so as to roll preferably on the floor surface, etc., and throws with the strength and skill of the infant. Ball-shaped training playground equipment that can perform strength training according to the degree of strength (Patent Document 2)
Etc. have been proposed.

Utility model registration No. 3162932 JP 2009-118951

On the other hand, the creators of the present application prepared various materials, and as a result of conducting a tactile survey on what kind of materials infants are interested in, irregular rugged and glittering materials are extremely rare from infants. I found that I was strongly interested in.

Therefore, the present invention proposes a ball playground equipment for infants, which is a hollow spherical body made of transparent plastic and is characterized in that irregularities are randomly formed on the outer circumference and the inner circumference thereof. ..

The semi-transparent plastic hollow spherical body according to the present invention is prepared by placing a thermoplastic resin plate material such as styrene in a spherical mold having random irregularities in a heated state, and then injecting air into the spherical body. By inflating along the mold, the main body is molded into a spherical shape with random irregularities on the outer and inner surfaces, and then unnecessary protrusions generated in the molding process are scraped off to obtain the obtained body.

The hollow sphere according to the present invention thus obtained gives a rugged feel when grasped by an infant or the like because the outer peripheral surface is randomly uneven.

Further, since the hollow spherical body according to the present invention is translucent and its outer and inner circumferences are irregularly uneven, light is diffusely reflected on the outer peripheral surface to the inner peripheral surface and exhibits a glittering appearance on the surface. , Infants show interest.

If a colorant is mixed in the plastic and the hollow spheres are colored to a highly saturated color,
The more vivid and brilliant appearance makes it easier for infants to recognize and further arouse their interest.

Therefore, infants are very interested in these hollow spheres whose surfaces are rugged and glittering, and they are very interested in grasping, stacking, or rolling, contacting multiple spheres, and making contact at that time. You will play by listening to the sounds.

Moreover, the hollow spherical body according to the present invention is most suitable as a playground equipment for infants because it does not roll far from the rugged surface and stops at a place where the infant can reach at high and high.

As is clear from these, the hollow spheres according to the present invention are rugged and glittering on the surface, and can promote the development of the infant's brain with strong tactile and visual stimuli, and can be used as a playground equipment for infants. It is the best one.

Perspective view showing an example of a ball playground equipment according to the present invention. Same as above vertical side view Explanatory drawing which shows the glitter state of the ball playground equipment which concerns on the invention of this application

For example, a styrene plate material is placed in a spherical mold with random irregularities in a heated state, and then air is injected into the styrene plate material to inflate it along the mold, so that the main body is spherical and random on the outer and inner surfaces. Infants who are formed into a shape with irregularities and then scraped off unnecessary protrusions generated in the molding process to form a translucent hollow sphere obtained by randomly forming irregularities on the outer and inner circumferences thereof. Ball playground equipment.

Hereinafter, the invention of the present application will be described based on the illustrated examples. 1 is a diameter of 6c according to the invention of the present application.
The hollow sphere 1 is a hollow sphere of about m. For example, a styrene plate material is placed in a spherical mold with random irregularities in a heated state, and then air is injected into the hollow sphere 1 to inflate it along the mold. This is obtained by molding the main body into a spherical shape having random irregularities on the outer and inner surfaces, and then scraping off unnecessary protrusions generated in the molding process.

The hollow spherical body 1 thus obtained has an uneven surface 2 randomly provided on the outer peripheral surface, and gives a rugged feel when grasped by an infant or the like.

Further, the hollow spherical body 1 is transparent and has a random uneven surface 2 on the outer peripheral surface thereof, and the inner peripheral surface of the hollow portion 3 randomly has an uneven surface 4 corresponding to the uneven surface 2. Therefore, the light is diffusely reflected on the outer peripheral surface to the inner peripheral surface, and has a glittering appearance on the surface.

In this way, the infant is very interested in the hollow sphere 1 having a rugged and glittering surface, and is gripped or rolled to play.

Moreover, the hollow spherical body 1 does not roll far from the place where the surface is rugged, and stops at a place where the infant can reach, such as high and high, and is therefore most suitable as a playground equipment for infants.

In short, the hollow spheres according to the present invention are rugged and glittering on the surface, and can promote the development of the infant's brain with strong tactile and visual stimuli, making them ideal as playground equipment for infants. is there.
