この発明は、靴、運動靴、サンダル等の履物に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to footwear such as shoes, athletic shoes, and sandals.
「従来の技術およびその問題点」
一般に履物として種々の履物が商品として永年にわたり
開発され、使用されてきた。しかし、従来の履物は特に
、その踵や履物の底面部の周囲が使用に伴って磨り減り
、特に第６図（ａ）に示すように踵部Ａが片寄って磨り
減るため、その片寄って磨り減った側に体重が集中して
、その側部Ｂに力がかかり、履物の全体形状が歪み、履
物の外表面形状を局部的に変形させてしまう。そして、
さらに上記側部Ｂに体重（力）がかかり、この側部８部
分から破損が始まるため、履物の短寿命化をきたしてい
た。"Prior Art and its Problems" In general, various kinds of footwear have been developed and used as commercial products for many years. However, in conventional footwear, the area around the heel and the bottom of the footwear wears down with use, and especially the heel part A wears out unevenly as shown in Figure 6 (a). Weight is concentrated on the side where the weight has been reduced, and force is applied to the side B, which distorts the overall shape of the footwear and locally deforms the outer surface shape of the footwear. and,
Further, weight (force) is applied to the side portion B, and damage begins from this side portion 8, resulting in a shortened lifespan of the footwear.
このような場合、従来はその履物を修理に出し、履物の
底部や踵部の取替え修理および踵部への金属製補強部材
の打ち込み等による修理を行なってきた。しかし、人件
費の高い現代では修理費用も高く、安価な履物の場合、
新たに購入した方が安い場合があり、さらに踵部の磨り
減り部分の金属製補強部材の打ち込み修理の場合には、
歩行時に金属が音を発し、騒音となる不都合もある。In such cases, conventionally, the footwear has been sent for repair, and repair has been carried out by replacing the sole or heel of the footwear, or by driving a metal reinforcing member into the heel. However, in modern times where labor costs are high, repair costs are also high, and in the case of cheap footwear,
It may be cheaper to purchase a new one, and if you need to repair the worn-out part of the heel by driving in a metal reinforcing member,
There is also the inconvenience that the metal makes noise when walking.
一方、履物の踵部の底面の片寄り磨り減りは、路上走行

し、足の骨折、ねんざ等を多発させ、さらには今後の人
口の高年令化時代への移行に伴い、老人において上記理
由による骨折、ねんざ事故が多発する心配がある。On the other hand, uneven wear and tear on the bottom of the heel of footwear causes unstable contact with the road surface while driving on the road, leading to falls, leading to frequent foot fractures and sprains, and furthermore, as the population increases in the future. With the transition to an aging society, there is concern that fractures and sprains will occur more frequently among the elderly due to the reasons mentioned above.
［問題点を解決するための手段」
本発明は上記従来の欠点を改善するためになされたもの

In order to prevent slips when walking or running using footwear 1,
The surface of the ceramic 2 may be grooved or have other uneven shapes, and if the ceramic is cylindrical, the hollow portion thereof may be filled with an anti-slip material such as rubber.

As shown in FIGS. 3(b), 3(c), and 3(d), they may be arranged or distributed in a non-uniform manner. Also, the same figure (
As shown in Figure 1(f), it may be arranged and distributed in a concentrated manner around the bottom of the footwear, but economically and effectively,
C) As shown in (d), it is better to concentrate the placement and distribution on the part of the bottom of the footwear that is subject to severe wear. Even more economical,
Effectively, as shown in FIG. 1(a), the mixture may be embedded in at least a part of the bottom of the heel of the footwear or in the peripheral area of the bottom, preferably in such a manner that it is exposed. In particular, as shown in Figure 1 (a), the exposed area of ceramics is increased in the part of the footwear where wear is the greatest, and the number of ceramics arranged and distributed is made denser so that wear and tear is minimized. The present invention also includes reducing the exposed area of ceramics in a portion and reducing the number of ceramics arranged and distributed.

As shown in Figures (a), (b), and (c), in areas where there is a lot of wear and tear, either embed them, increase the amount of mixture, or concentrate the same arrangement densely, and increase the length in the depth direction. lengthen. Further, in the case where ceramics are mixed into the soles of athletic shoes in the present invention, it is preferable that the mixed ceramics is a fine powder in the form of microspheres, but other shapes may be used.

により接着材とともに挿入すればよい。In the present invention, a known method can be used to mix ceramics into at least a portion of the sole of footwear, and the method is not particularly limited to the following example. That is, when the bottom member of the footwear is made of rubber or synthetic resin, ceramics may be mixed in during the molding process, and if necessary, a known adhesive may be used to bond the ceramic molded body to the rubber and synthetic resin. Further, when the bottom member is made of natural leather, wood, etc., holes may be made at key points and ceramics may be inserted therein together with an adhesive if necessary.
また、使用するセラミックスを第３図（ｂ）に示した円

Furthermore, in the present invention, it is also possible to cover and bond the whole or part of the bottom surface of the footwear, and the periphery of the bottom, preferably the whole or part of the bottom surface of the heel, and the periphery of the bottom, with a ceramic plate. This bonding can be performed by a known method using a known adhesive or the like.

By preventing deformation and local deformation, it is possible to prevent damage from the deformed area and its surroundings, thereby greatly improving the durability of footwear, and further reducing the weight. It also does not make noise like a sex reinforcing member.

れらを防止し健康の維持に大変有効となる。In addition, as mentioned above, the wear and tear on the soles of the footwear, mainly at the heel, is almost eliminated, which greatly reduces the occurrence of fall accidents due to unstable contact between the soles of the footwear and the road surface while walking. This can significantly reduce the incidence of foot fractures, sprains, etc. Extremely uneven heel wear causes a change in the center of gravity of the user's body, which causes bending of the arms and deformation and compression of internal organs, causing health problems. The footwear according to the invention prevents these problems and is very effective in maintaining health.

It will be done. In this way, it is possible to simultaneously obtain the well-known health-promoting effects of magnetic force, such as increasing blood flow in the legs.

せず、外観形状にも異常は認められなかつた。[Example 3] Silicon nitride is molded into a fan shape, and the obtained sintered body 8 is attached to the heel portion 9a made of synthetic rubber of a high heel 9 shown in FIG. 5(a) with fan-shaped ceramics as shown in FIG. Four sintered bodies were arranged in a circle, embedded, and bonded. When this shoe 9 and commercially available high heels made of the same basic material were used on a daily basis and the condition was examined after one year, it was found that in the conventional products, the heel part wears out one side and at the same time the end part spreads out, and the external shape also changes. Although deformation occurred, the product of the present invention did not suffer from abrasion of the heel or flowering phenomenon, and no abnormality was observed in the external shape.
「発明の効果」
以上説明したように、この発明に係るセラミックス混合
底付き履物は、その底の少なくとも一部をセラミックス
から構成したものである。"Effects of the Invention" As explained above, the footwear with a ceramic mixed sole according to the present invention has at least a portion of its sole made of ceramics.

発することもない。Therefore, even if the footwear with a ceramic-containing sole of the present invention is used for a long period of time, it is possible to prevent wear and tear of the sole, mainly the heel part, especially uneven wear and tear, and deformation such as distortion of the three-dimensional shape of the outer surface of the footwear. This prevents local deformation, prevents damage from the deformed area and its surroundings, greatly improves the durability of the footwear, and further reduces the weight. It also does not make noise like reinforcing members.

の維持に大変有効となる。In addition, as mentioned above, there is almost no wear and tear on the soles of footwear, mainly at the heel, which greatly reduces the occurrence of falls due to unstable contact with the road surface while walking, and thereby It is possible to significantly reduce the incidence of fractures, sprains, etc. Furthermore, extreme one-sided wear of the heel has caused a change in the center of gravity of the user's body, which has led to bending of the arms and deformation and compression of internal organs, causing health problems. Footwear related to this is very effective in preventing these and maintaining health.
