この発明は、衝撃吸収性の靴底に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This invention relates to a shock-absorbing shoe sole.
（従来の技術）
出願人は先に、特願昭59−135818号（特開昭61
−13902号）によつて剛性板間に低反発弾性発泡

積層した運動靴を提案した。(Prior art) The applicant previously filed Japanese Patent Application No. 59-135818 (Japanese Patent Laid-Open No. 61
-13902), we proposed an athletic shoe in which a shock absorbing material made by bonding a low-resilience foam between rigid plates was laminated on the heel of the shoe sole.

まい耐久性に欠ける欠点があつた。 Shoe soles equipped with such shock-absorbing materials exhibit relatively good shock absorption and landing stability during light running such as normal walking or jogging, but they are also used in tennis, basketball, soccer, and long-distance running. When the landing impact pressure is large, such as during a jump, a load of more than three times the body weight pressure is concentrated on the part corresponding to the lower protrusion of the calcaneus at the initial stage of landing, so the landing impact pressure is transferred to the heel. It cannot be absorbed sufficiently in areas corresponding to the lower protrusions of bones, and in addition, such low-resilience foams have a large compression set, and have the disadvantage of being compressed and deformed with long-term use, resulting in a lack of durability. Ta.

がある。 As for the hardness, those having a hardness of 20° to 70°, more preferably 30° to 50° according to JIS K6301 spring type hardness test type A are used. If the hardness is less than that, the shock absorption property due to compressive deformability will be good, but the recovery power will be poor, the permanent deformation will be large, and the durability will be reduced. Moreover, if the hardness is higher than that, the compressive deformability tends to decrease and at the same time, the shock absorbability tends to decrease.
透明弾性体１には水平断面が円形、だ円形、多

設けられている。 The transparent elastic body 1 is provided with a large number of compression holes 14, 14, . . . whose horizontal cross section is circular, oval, or polygonal in the vertical direction.

止されることになり好都合である。 In this invention, the compression holes 14, 14 are formed in the outer side 11 of the transparent elastic body and the inner side 12 thereof.
Specifically, when the compression holes 14, 14... are formed to have the same size overall, they are arranged concentrated on the outer side 11 so that the surface area occupation rate is larger than that of the compression holes 14, 14... In addition, when the compression holes 14, 14... are arranged uniformly throughout, the outer side 1
The compression holes 14', 14'... arranged in the shoe sole 1 are formed larger than the compression holes 14'', 14''... arranged in the inner side 12, and the outer side 11 is connected to the heel of the sole 2. If the inner side 12 is located in the inner side 22 of the heel of the sole 2 and embedded in the heel of the shoe sole, the sole 2 can be easily removed during normal walking and running. The maximum impact pressure at the initial stage of landing, which is applied to the outer side 23 of the heel of the shoe, is absorbed more effectively by the compression holes 14, 14 formed in the outer side 11 of the transparent elastic body. When the heel inner side 22 of the sole 2 lands on the ground following the landing of the heel outer side 23, the compression holes 14, 14... formed in the inner side 12 of the transparent elastic body 1 close to the outer side. Since the compression holes 14, 14, . This is advantageous because the medial side 22 of the heel 2 is not excessively internally rotated and overpronation is prevented.

きる。 In this invention, if the compression holes 14, 14... are narrowed at their central portions 141, 141... and the cross-sectional shape in the vertical direction is formed into a zigzag shape,
As shown by the arrow in FIG. 2, the landing shock is absorbed from the radial direction of the lower surface, and the landing shock that cannot be absorbed by the compression holes 14, 14... is dispersed along the wall surface 140 in the radial direction of the upper surface. As a result, the impact cushioning properties are improved, and the elastic recovery power is also improved, making it possible to make the wearer's comfort even better.

は塵埃が侵入することがないので好都合である。 In this invention, if the windows 21, 21 provided opposite to the heel side of the sole 2 are airtightly covered with transparent synthetic resin films 211, 211, the windows 21, 21 can be passed through the sole 2. This is advantageous because it prevents water or dust from entering the shoe.

久性が良好である。(Actions and Effects of the Invention) Since this invention is configured as described above,
When walking or running while wearing the shoes, the landing impact pressure applied to the heel of the sole 2 is absorbed by the compression of the compression holes 14, 14 formed in the transparent elastic body 1. The body 1 has a smaller compression set than conventional low-resilience foams, and the compression set does not change even after long-term use, so it has good durability.
