DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball for restoring a hard or soft ball to a play ball, a method for restoring a play ball, and a play ball.

2. Description of the Related Art Conventionally, for example, when a seam or thread of a ball of a baseball, which is a kind of game ball, or a softball (game ball) is damaged, the seam or thread is manually worked. It was sewn together and repaired so that it could be reused. In the case where a hard ball is driven by using a batting machine, for example, the seams of the scalp in about three days,
The thread or cork itself was damaged and could not be used.

However, even if the hard sphere is repaired so that it can be reused, if the scalp itself is damaged, it must be discarded. In this case, there is no other option but to discard the hard balls that cannot be reused by each user. In other words, even if the core of the hard sphere can be used without any damage, it must be discarded when the scalp of the hard sphere has been completely damaged. The core of the hard sphere is made by corrugating a small ball of cork material, covering it with a rubber material of appropriate thickness, winding it in a spherical shape with a wool material, and further rolling the outer periphery in a spherical shape with a yarn material. You. And this is 2
A piece of scalp is covered and sewn to form a spherical hard sphere. In such hard balls, rubber, cork, thread, and the like are used, and there are environmental problems associated with disposal, pollution problems such as generation of dioxin, and countermeasures are demanded. The present invention has been made in view of the above circumstances, and it is possible to restore a low-cost playing ball with respect to a hard ball or a softball using a reusable core, and dispose of the core.

Embodiments of the present invention will be described below in detail. FIGS. 1 and 2 show a hard ball 1 which is a kind of a play ball according to the present embodiment.
Is formed of a material selected from an artificial leather material, a synthetic leather material, or a natural leather material, includes a stitch-shaped portion 2 of a predetermined shape for hanging a finger of a pitcher exposed on the outer periphery, and has a spherical shape as a whole. And a cut portion 4 which is inserted into a cut portion 4 provided in a part of the cut skin 3 to form the cut portion 4.
And a reusable core body 6 hermetically sealed in the envelope 4 by bonding and sealing with an adhesive 5. The cut portion 4 has a slit shape as shown in FIG. 1 (a), a batten-shaped slit shape as shown in FIG. 1 (b), or a slit shape as shown in FIG. 1 (c). As shown in FIG. Notch 4 in other states
It may be. In short, the cut portion 4 in any state as long as the reusable core body 6 can be inserted into the envelope 3.
It may be. The adhesive 5 may be applied to the outer periphery of the core body 6, the inner periphery of the envelope 3, or any one of the edges 4 a and 4 b of the cut 4. next,
A method of manufacturing the hard ball 1 will be described with reference to FIGS. First, as shown in FIG. 3, the sheath 11 is peeled from the used hard ball 10 in which the sheath 11 has been damaged or the seam portion has been damaged, and the spherical core 6 is taken out. As a means for peeling the bulb 11, a known dedicated peeling apparatus (not shown) is used, or a manual peeling operation using a cutter or the like is used. Next, as shown in FIG. 4, a stitch-like portion 2 of a predetermined shape which is made of a material selected from an artificial leather material, a synthetic leather material, and a natural leather material and is exposed on the outer periphery is provided. Is prepared, for example, by a press machine. A cutout 4 for inserting the core body 6 is formed integrally with a part of the envelope 3. next,
As shown in FIG. 5, the cut portion 4 of the envelope 3 is opened,
The reused core 6 taken out from the used hard ball 10 is inserted into the envelope 3. At this time, the adhesive 5 is applied to the outer periphery of the core 6, the inner periphery of the sheath 3, or both edges 4 a and 4 b of the cut portion 4. Next, as shown in FIG. 6, a force in a direction of joining the edges 4 a and 4 b of the cut portion 4 to the outer periphery of the envelope 3 by the dedicated joining tool 20 illustrated in FIG.
(Indicated by arrows), the edges 4a and 4b are joined and applied to the outer periphery of the core body 6, the inner periphery of the envelope 3, or both edges 4a and 4b of the cutout 4, respectively. The edges 4a and 4b are adhered and fixed by the adhesive force of the adhesive 5, and the reusable core body 6 is hermetically sealed inside the envelope 3. Thus, the hard sphere 1 as shown in FIGS. 1 and 2 can be manufactured. As shown in FIGS. 6 and 7, the joining tool 20 includes a pair of hemispherical joining curved portions 21 and 21 having a curvature corresponding to the outer periphery of the envelope 3 and a pair of joining curved portions 2.
A pair of operation arms 22 and 22 that support the first and the second and that are arranged in an intersecting manner, and the operation arms 22 and 22 that are attached to the intersection of the pair of the operation arms 22 and 22 can be rotated in the directions indicated by arrows in FIG. And a shaft pin 23 to be supported. When applying a force in the direction of joining the edges 4a and 4b of the cutout portion 4 to each other, an end protruding outward from the shaft pin 23 (opposite to the pair of joining curved portions 21 and 21). The operation force in the direction of the arrow is applied by holding the side by hand. As means for applying a force in the direction of joining to the edges 4a, 4b of the cutout 4, there are various other forms shown in FIG. 6, for example, although not shown, a press machine having a simple configuration is used. Is inserted into the sheath 3 into which the reusable core body 6 is inserted, and the edges 4a and 4b of the cutout 4 are internally joined by applying tension with an automated arm or the like, and press bonding is performed. It is also possible to plan. In addition to the case where the envelope 3 is integrally formed by a press machine, it is also possible to form by hand sewing or processing, or mechanical sewing using a machine or the like. Further, the present invention can be applied to low-cost restoration of a softball using an elastic material as a core in addition to the hard ball 1. According to the present embodiment, the hard ball 1 or the softball can be restored at a low cost by using the core 6 of the hard ball 1 which is reused, the amount of discarded core 6 is reduced, and environmental problems and pollution are reduced. It is possible to provide a game ball restoring scalp 3 that can contribute to prevention, a method of restoring and manufacturing the hard ball 1 and a restored hard ball 1.

According to the first and second aspects of the present invention described above, it is possible to restore a game ball at a low price by using a core for recycling a game ball, thereby contributing to environmental and pollution control. A ball for restoring a play ball, which is a hard ball or a soft ball, can be provided. Further, according to the invention of claims 3, 4 and 5, a game ball can be produced at a low cost by using a material selected from artificial leather material, synthetic leather material or natural leather material and a reused core. It is possible to provide a method of restoring a game ball that is a hard ball or a soft ball that can be restored. Furthermore, according to the present invention as set forth in claims 6, 7 and 8, the material selected from artificial leather material, synthetic leather material or natural leather material, and the core for reuse are used, and at low cost. In addition, it is possible to provide a game ball that is a hard ball or a soft ball that can contribute to environmental and pollution control.
