この発明は、靴底用衝撃吸収材に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a shock absorbing material for shoe soles.
（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
体を介在接着させた衝撃吸収材を提案した。(Prior art) The applicant previously filed Japanese Patent Application No. 59-135818 (Japanese Patent Laid-Open No. 61
-13902) proposed a shock absorbing material in which a low-resilience foam was interposed and bonded between rigid plates.

部に対応する部分において充分吸収できず、しか
もこのような低反発弾性発泡体は圧縮永久歪が大
きく、長期にわたる使用によつて圧縮変形してし
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.

なれば、圧縮変形性が低下して衝撃吸収性が低下
するからである。 In this invention, the hardness of the transparent soft elastic body 1 is
The reason for limiting the hardness to 20° to 60° is that if the hardness is lower than this, the shock absorption properties due to compression deformability will improve, but the elastic recovery power will decrease, compression set will increase, and durability will decrease. This is because if the hardness is higher than that, the compressive deformability will decrease and the impact absorption will decrease.

In this invention, the compression holes 14, 14... are formed in the elastic body so that the surface area occupancy is larger on the outer side 11 of the elastic body than on the inner side 12. 1, the compression holes 14, 14... are arranged in a concentrated manner on the outer side 11, and the compression holes 14, 14... are arranged throughout the elastic body 1 in the same size. When the compression holes 14', 14', etc. arranged on the outer side 11 are arranged uniformly, the compression holes 14', 14'... are formed larger than the compression holes 14'', 14''... arranged on the inner side 12. , its outer side 11 is the heel outer side 2 of the sole 2
4, if the inner side 12 is located on the inner side 23 of the heel of the sole 2 and embedded in the heel of the sole, the outside of the heel of the sole 2 can be moved during normal walking and running. The maximum impact pressure applied to the side part 24 at the initial stage of landing is due to the compression holes 14,1 formed in the outer side part 11 of the elastic body.
4, when the inner heel side 23 of the sole 2 lands on the ground following the landing of the outer heel side 24 of the sole 2, the inner side of the elastic body 1 1
The compression holes 14, 14... formed on the outer side 11 have a smaller surface area occupation rate than the compression holes 14, 14... formed on the outer side 11.
2, the compressive deformation rate is suppressed more than that of the outer side portion 11, and the inner side portion 23 of the heel portion of the sole 2 is not excessively adducted, and overpronation is prevented. This is convenient.

The side wall 10 composed of the spherical surface 101 of the shock absorbing material for shoe soles of the present invention is exposed on the side surface of the sole 2 or can be freely viewed through a see-through window formed on the side surface of the heel portion of the sole 2. If the shoe is used by being laminated or embedded in the transparent elastic body 1, the landing impact pressure applied to the heel of the sole 2 when walking or running while wearing the shoe is absorbed by the compression holes 14, 14 formed in the transparent elastic body 1. The transparent elastic body 1 has a smaller compression set compared to conventional low-resilience foams, and the compression set does not change even after long-term use, making it durable. is good.

4. When the spherical surface 101 formed on the side wall 10 is a convex spherical surface, the compressive deformation when worn is magnified, and when the spherical surface 101 is a concave spherical surface, it is reduced and the side surface of the sole 2 or transparent view is shown. Since it can be seen through the window, the impact absorption effect can be visually promoted.
