TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball for a ball that is a game of continuously kicking the ball so as not to drop it on the ground, and a method of manufacturing the ball.
[0002]
[Prior art]
Since ancient times, it has been loved by people of all levels as well as courts and public courts as a sport in which Kemari keeps kicking the ball so that it does not drop to the ground. Was. However, during the Meiji Restoration after the collapse of the Shogunate, the Asukai family, the sect of Kemari, was abandoned by the wave of national modernization and abolished. Now, Kemari, which has a history of 1000 years, is only organized in two places, the Kemari Preservation Society in Kyoto and Shikoku Kintora Shrine.
[0003]
Indispensable for such a ball are balls, costumes, shoes, ball gardens, etc. Among them, balls are the most important. However, at present, there is no place that deals with balls for kemari, and even preservation organizations are only making imitations, so it is possible to make only far from perfect ones. Naturally, soccer balls, beach balls, and the like are used as substitutes because there is no place to accept an order and a new ball cannot be obtained.
[0004]
In order to obtain a new ball, the ball must be restored using the manufacturing method described in the old book. According to the book, the necessary materials are the raw skin of a deer, the back skin of a horse, the seaweed, glue, chalk (white pigment made by baking shells), and eggs. The reason for using the deer's hide is that when it is kicked up, the sound of the bones and the sound of the bones is good. In making a ball, first cut two skins from deer rawhide in a circular shape, arrange the two into a round shape, and superimpose the peripheral parts. Stitch together. Then, a bag of deer skin is formed, and several grains of barley are stuffed into the inside through a small hole provided at one place, and the barley is filled with a full barley, dried to a predetermined roundness, and dried. Barley has a large particle size. After drying, the entire surface of the deerskin bag is coated with white powder using glue using glue and glue to form a white coating layer. In addition, polish it with egg white and perform polishing. Then, take out the barley little by little and close the small hole in the bag to complete the ball.
[0005]
[Problems to be solved by the invention]
However, when the ball restored in this way is used, it tends to lose its elasticity in a short period of time and the coating layer is easily removed. Therefore, the restoring force is small, and the overhaul must be performed in a short time. In addition, during production or overhaul, several grains of barley must be packed from the small hole to fill the barley, or the packed barley must be taken out little by little. Barley must be packed firmly in a bag with a stick or the like, and the bag must be rounded, so that it is easily crushed, difficult to get out of a small hole, and cannot be used again.
[0006]
The present invention has been made in view of such conventional problems, and has an appropriate hardness and elasticity, has difficulty in removing a coating layer, has a large restoring force, and does not require overhaul in a short period of time. It is an object of the present invention to provide a method for manufacturing a ball for a kimari, which can easily form a deer skin bag during work such as production and overhaul, and can reduce labor and time burden.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the case of the kemari ball according to the present invention, a coating layer made of titanium oxide and an adhesive containing rosin is provided on the entire surface of the deerskin bag.
[0008]
Further, in the method for manufacturing a ball for kemari according to the present invention, a step of packing a filler into the inside of a deerskin bag, forming a predetermined roundness, and removing the filler is performed. Then, granular plastic is used as a filler for forming roundness.
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the attached FIGS.
FIG. 1 is a front view of a ball for kemari to which the present invention is applied, and FIG. 2 is a plan view showing a state in which a number of seam cuts are provided on a circular raw bark of a deer used for manufacturing the ball. For the production of this ball for kemari 1, two round deer skins 2 are used. As shown in FIG. 2, a large number of, for example, 87 stitches 4 for sewing are formed on each deerskin 2 along the peripheral portion 3 at substantially equal intervals. However, it is difficult to stretch the deer skin 2 as it is. Therefore, as a result of repeated trial and error, it has been found that, if the deer skin 2 is immersed in bran paste and then operated under the high temperature and high humidity of midsummer, it is easier to lick the three-dimensional object than before. The deerskin 2 may be dipped in bran paste and then dipped in a seaweed to facilitate processing.
[0010]
Then, in the middle of summer, the two deerskins 2 are arranged so as to be rounded, and the peripheral portions 3 are overlapped with each other. For example, half of the peripheral portion 3a of the deerskin 2a on the left is inside, and the deerskin 2b on the right is One half of the peripheral portion 3b is arranged outside, and the other half of the remaining peripheral portions 3a, 3b are arranged oppositely. The overlapped portion is sewn using the back skin of the horse as the band strap 5. At this time, two horse leather straps 5 are arranged inside and outside, and the inner horse leather strap 5 is sewn together by the inner and outer peripheral portions 3 of the deerskin 2 overlapped through the adjacent cuts 4 to form the outer horse leather strap 5. Sew one overlying outer peripheral portion 3 of deerskin 2 through each adjacent cut 4. It should be noted that the deerskin 2 and the horseshoe string 5 both have their hair removed.
[0011]
After the bag 6 made of deerskin is formed in this way, the inside of the bag 6 is filled with granular plastic through small holes 7 and is filled to the full. At this time, it is good to select and use a material having a small particle size and a high hardness so that it can be easily taken in and out of a granular plastic generally used as a raw material of a plastic molded product. Then, the granular plastic can be packed into the deerskin bag 6 sufficiently firmly using a stick or the like, and the bag can be rounded and easily formed into a predetermined shape. In addition, the granular plastic has a small particle size and is easily packed without being crushed, so that the labor and time burden required for the packing operation can be reduced.
[0012]
After being sufficiently dried on the sun or the like, a mixture of titanium oxide and an adhesive containing rosin is applied to the entire surface of the deerskin bag 6 filled with the granular plastic 8 as shown in FIG. 9 is formed. This titanium oxide is a white pigment used in cosmetics and the like, and is a substance that is insoluble in cold and hot water and has high acid resistance. In addition, rosin is a colorless, transparent, highly viscous liquid substance containing rosin and turpentine, rosin acts as a non-slip, and turpentine acts as a leather-retaining agent. Before the covering layer 9 is provided on the entire surface of the deerskin bag 6, a glue-coated and dried base treatment may be performed.
[0013]
When such a white coating layer 9 is provided, it becomes the white ball 1, and the deerskin bag 6 has appropriate hardness and elasticity, and it becomes difficult to remove the coating layer 9 even when an impact due to a kicking is applied. Therefore, ball 1 is resilient and does not need to be overhauled in a short time. Conventionally, white powder was formed by melting glue with glue, but the hardness and elasticity were insufficient, and if the kicking was continued, the coating layer was removed within a short period of time.
[0014]
After the coating layer 9 is dried, egg white is applied thereon to make it gloss, and the granular plastic 8 as a filler is taken out from the inside. At this time, the granular plastic 8 has a small particle size and is not crushed, so that it can be easily taken out. Finally, when the hole 7 is closed by sewing, a ball 1 having a major axis of about 20 cm and a minor axis of about 15 cm is completed. The reason why the center of the ball 1 is squeezed with the horseshoe string 5 to have a shorter diameter is to increase the restoring force.
[0015]
In the above-described embodiment, the coating layer 9 made of a mixture of titanium oxide and an adhesive containing rosin was formed on the entire surface of the deer skin bag 6, but a coating layer formed by dissolving titanium oxide in water and applying it first was formed. After drying, an adhesive containing rosin is further applied on the coating layer to form a coating layer. In addition, you may use a leather retaining agent other than turpent oil of rosin as a leather retaining agent.
[0016]
【The invention's effect】
According to the present invention described above, in the invention according to claim 1, by using a cold, insoluble in water and highly acid-resistant titanium oxide as a white pigment constituting the coating layer, and further using an adhesive containing rosin, The turpentine oil contained in rosin works as a leather-retaining agent, and the rosin contained in rosin also provides a moderate hardness and elasticity due to the non-slip effect, making it difficult to remove the coating layer even when impacted by kicking. The restoring force can be increased to avoid overhaul for a long time.
[0017]
According to the second aspect of the present invention, the granular plastic is used as a filler for forming roundness, so that the granular material has a small particle size so that it can be easily inserted into and removed from a small hole of a deerskin bag, and has a large hardness so as not to be crushed during packing. Plastic can be selected and used. Therefore, the shape of the bag made of deer skin can be easily prepared at the time of work such as production of a ball or overhaul, and labor and time burden can be reduced.
