A sandal according to claim 8 is the sandal according to any one of claims 1 to 7, wherein the base has a plurality of non-slip portions formed on the lower surface in a concavo-convex shape in a direction substantially orthogonal to the longitudinal direction of the base. It has a configuration. The method for manufacturing a sandal according to claim 9 is the method according to any one of claims 1 to 8.
In any one of JIS, the JIS-
International rubber hardness of 50-70IRH according to K-6253
A base member forming step of forming a base member by adhering a plurality of columnar members each having a diameter of 5 to 35 mm and having a substantially half-moon shape in cross section on the upper surface of the base member made of natural rubber or synthetic rubber of D; The base member obtained in the base member forming step is cut into a predetermined shape and cut to form a base portion, and a base portion formed in the base portion forming step is attached to the strap portion by the fixing bracket. And a step of fixing the thong portion for fixing.

Here, the material of the base of the base is natural rubber (N
R), synthetic rubber (SR) such as vulcanized rubber is used.
The base of the base has an international rubber hardness of 50 to 70 IRHD, preferably 60 to 64 IRH according to JIS-K-6253.
D is preferable. International rubber hardness of the base is 60IR
As it becomes smaller than HD, the base part becomes too flexible, and there is a tendency for it to become shattered or to bounce off when walking. Especially, when it becomes smaller than 50IRHD, the tendency becomes remarkable. 64 IRH
As it becomes larger than D, the bottom of the base becomes too hard, and the followability tends to deteriorate when walking.
When HD is exceeded, the tendency becomes remarkable, and thus both are not preferable. Further, it is preferable that the thickness of the bottom of the base is formed so as not to be affected by the small stones and the like of the base and not to deteriorate the walking function and the like. If the thickness of the platform bottom is too thick, it tends to become hard, and if it is too thin, it tends to be too soft, and it tends to be easily fatigued due to the influence of small stones on the ground. Specifically, it is preferably in the range of 2 to 10 mm, preferably 2 to 5 mm.

Examples of the material of the columnar member include wood such as cedar, cypress, and paulownia, and hard synthetic rubber in which talc, calcium carbonate, etc. are combined with the above-mentioned synthetic resin. Examples of the shape of the columnar member include a substantially half-moon-shaped cross section, or a shape in which fine cross-sectional substantially half-moon shapes are arranged in parallel. Also, the columnar member is
By providing the base portion having a substantially trapezoidal cross section, the base portion can be curved to some extent in the longitudinal direction, and it is possible to prevent the base portion from being curved more than necessary due to contact between the adjacent base portions. There is no risk of spraining of the toes, it is safe, it is possible to obtain followability, and it is comfortable to wear. Further, when the columnar members are arranged side by side, the bending effect can be obtained also by providing a gap between the columnar members. or,
The columnar member has a diameter (φ) of 5 to 35 mm, preferably 1
The one having a thickness of 0 to 25 mm is used, which is excellent in reliability because the meat of the foot is not pinched as well as the acupressure effect. As the diameter (φ) of the columnar member becomes smaller than 10 mm, the number of parts increases and the manufacturing process tends to be complicated, especially 5 mm.
As the size becomes smaller, the tendency becomes remarkable, and the meat of the foot is easily pinched, which causes pain and discomfort. Further, as the diameter (φ) of the columnar member becomes larger than 25 mm, it becomes difficult to use common parts in changing the size (S, M, L), etc., and the cost increases. Further, if the diameter is larger than 35 mm, the acupressure effect is reduced, and it is necessary to have a plurality of fine crescent-shaped cross sections in parallel with the acupressure part. Further, the substantially central portion in the longitudinal direction of the table surface portion means a portion on which the arch touches. As the table surface part, the front half in the longitudinal direction of the table surface part may be a plate-shaped member,
Productivity can be improved.

The material of the wood of the columnar member is not particularly limited, but it is selected from the viewpoint of color tone, water absorption, drying property and scent. By using wood for the columnar member, it is possible to effectively use the strength direction due to the wood grain to prevent cracks and to make a product that is hard to slip and easy to wear. In particular, cedar and cypress have good grain and have a unique scent. Further, it has excellent splitting properties and is easy to cut and perform other processing, and has excellent workability. In particular,
As the wooden columnar member, it is preferable to use burned cedar in which the surface of cedar wood is burnt with various chemicals or the like and then polished to expose the wood grain. Here, as the columnar member, it is possible to use a bamboo material such as Moso bamboo or bamboo, but in this case, even if the bamboo material is sufficiently dried, it absorbs moisture and causes the generation of harmful insects and molds, which is extremely unsanitary. However, it is not preferable because the surface of the bamboo material is likely to be discolored, which impairs the appearance and shortens the useful life.
Further, bamboo is not preferable because it may slip when touched with water and may break. Furthermore, in order to solve these problems,
After boiling the bamboo, sterilization treatment or chemical injection treatment is required, which is not preferable in terms of workability. Further, even if a bamboo material is attached to the upper surface of the bottom of the base, the adhesive area is small and the adhesiveness is extremely low, so that the bamboo material is easily peeled off. In addition, it is not preferable because of low moldability such as push-cutting in manufacturing. Further, since it is difficult to make the heights uniform, it is not preferable in terms of mass productivity and product uniformity.

Examples of the thongs include cloth, rubber, synthetic resin such as vinyl, synthetic leather and the like. The size of the sandals of the present invention is not particularly limited, but it is extremely suitable for producing for adults, women, children, etc., especially in S, M, L sizes, and is mass-produced at low cost. The property is improved.
