定の硬度、粘弾性特性及び厚さを選択する必要がある。Hereinafter, the present invention will be described in detail. First, reference is made to FIGS. FIG. 1 shows an arch pad 10 for the left foot as viewed from the back side of the foot, and includes a viscoelastic polyurethane pad 11 and a cloth 12 bonded to the surface thereof. As shown in FIGS. 2 and 3, the viscoelastic polyurethane pad 11 has a downwardly convex and gentle arc shape, has an arc shape in both the vertical and horizontal directions, and has a convex lens-like curved surface as a whole. I have. The outer shape is a rectangle or a parallelogram corresponding to the horizontal arch and the vertical arch (inside and outside), and the corners are rounded. FIG. 4 shows a comparison with the related art.
The upper surface of the viscoelastic polyurethane pad 11 is flat and has a fabric 12 integrally bonded thereon. The fabric 12 is wider than the contour of the viscoelastic polyurethane pad 11 by a substantially constant width. The outer dimensions of the arch pad 10 are such that the arch part is covered substantially, and the maximum thickness is 3 to 15
mm, especially 5 to 10 mm, is suitable. The required thickness depends on the hardness. For low hardness, the thickness may be thicker, and for high hardness, the thickness may be thinner. Usually, the hardness is from 0 to 30 according to JISA. However, in order to obtain a predetermined effect, it is necessary to select a predetermined hardness, viscoelastic property and thickness according to the symptoms.

力を除くと数秒以内に原形を回復する。The viscoelastic polyurethane which can be used as the material of the viscoelastic polyurethane pad 11 in the present invention may be selected from any known materials. Preferably, a mixture of a high molecular weight polyol and a low molecular weight polyol is used. A polyisocyanate is reacted under an excess of OH to produce an ultra-low hardness polyurethane.
No. 26,330 discloses a blend of poly (1,2-propylene glycol) and N, N, N ', N'-tetrakis (2-hydroxypropyl) ethylenediamine in at least one stoichiometric amount. A polyurethane elastomer reacted with an aromatic isocyanate may be used. This viscoelastic polyurethane is a polyurethane elastomer having a low compression set and a slow recovery from compression, and is a material suitable for the purpose of the present invention. Further, in order to improve the temperature-dependent energy absorption (impact attenuation), a viscoelastic polyurethane described in JP-A-61-19618 to which a monohydric alcohol component is further added may be used. In this case, the polyol and isocyanate are reacted in equivalent amounts and do not contain excess hydroxy groups. In any case, the hardness is 0 to 30 according to JIS A,
Feels hard, 0 is soft and easily deformed by external force,
It recovers its original form within a few seconds when the power is removed.

ら通常の中敷きと同様な感触が得られる。[0007] To use the arch pad 10 of the present invention, the viscoelastic polyurethane pad 11 is turned down, and the cloth 12 is applied to the bottom of the arch of the foot. When walking in this state, the arch pad bends and comes into close contact with the arch bottom surface.
Therefore, there is no problem even if the side contacting the sole is not curved along the arch. Since the viscoelastic polyurethane pad 11 shows a slight adhesiveness, it is hard to be displaced from the position when placed in the shoe. On the other hand, since the fabric 12 is in contact with the foot, a feeling similar to that of a normal insole is obtained.

A molding machine including a lower mold 13 having a lens-shaped molding cavity 15 for receiving a raw material for viscoelastic polyurethane and an upper mold 14 having a flat bottom surface is described. use. A predetermined amount of the raw material measured in advance is charged into the molding cavity 15, and the cloth 12 is put thereon. The upper and lower molds 13 and 14 are closed, and the molds are heated to a predetermined temperature and held for a predetermined time. As a result, crosslinking occurs, and an arch pad in which the desired viscoelastic polyurethane pad 11 and fabric 12 are completely integrated is obtained. Further, since the molding cavity is provided in the lower mold, the molding operation is much easier than in the case where the cavity is formed in the upper mold.

ある。As described above, unlike the conventional arch pad, the arch pad of the present invention comes in contact with the entire arch portion, so that its position can be easily determined. Due to its high adhesiveness, it is hard to shift from its position when placed above and below the insole. Therefore, the arch pad of the present invention can be easily used by anyone. According to the structure of the present invention, the manufacture of the arch pad is easy and suitable for mass production. In use, a part of the pad can be freely cut and thinned according to the symptoms of the user.
