- the front side in the front-rear direction extends linearly from the lower plate 3 to the upper plate 2 between the upper and lower plates 2 and 3.
- the application of the present invention is not limited to these.
- FIGS. 10 to 14 show saw structures according to other embodiments 4 to 4D of the present invention, and each figure shows a different embodiment.
- the same reference numerals as those in the first to fifth embodiments denote the same or corresponding parts.
- the force described by taking the connecting portion 5 as an example can be applied to other connecting portions.
- the inner surface of the connecting portion 5 force The standing wall surface 50 extending upward while being substantially orthogonal to the lower plate 3,
- the inclined surface 51 extends obliquely upward from the upper end of the wall surface 50 toward the outer side in the shoe width direction. That is, in this case, a gap is formed between the lower surface 2 a of the upper plate 2 and the inclined surface 51 of the connecting portion 5.
- This also causes the lower surface 2a of the upper plate 2 Part plate ⁇
- the inner edge J of the connecting part 5 to the flat surface facing the upper surface J edge moves to the outside of the inner edge J edge of the connecting part 5 lower plate 3 upper surface of the connecting part 5 ing.
- the inner side surfaces (inner side surfaces in the shoe width direction) of the connecting portions 4, 5, 6 are linear from the lower plate 3 to the upper plate 2 between the upper and lower plates 2, 3.
- the upward load acting on the lower plate 3 acts on the upper plate 2 as it is via the connecting portion 5.
- the entire sole structure can be reduced in weight by the gap formed between the lower surface 2 a of the upper plate 2 and the inclined surface 51 of the connecting portion 5.
- the connecting portion 5 has a truncated pyramid shape when viewed from the side between the upper and lower plates 2 and 3 (see FIG. 8 etc.), so that the shoe wearer is walking or running. Inside, the connecting portion 5 is sheared and deformed appropriately forward (back side of FIG. 10), and the upper plate 2 swings (tilts) forward. As a result, a smooth ride feeling can be obtained in the same manner as in each of the above-described embodiments (this also applies to other embodiments 4A to 4D below).
- the inner surface of the connecting portion 5 extends upward while being substantially orthogonal to the lower plate 3 and the upper plate 2. and a substantially orthogonal cytoplasm one upright wall surface 5 0 2 extending downward, substantially V-shaped notches 5 2 formed between these upright walls 5 0 There 5 0 2 Te. That is, in this case, the gap C 2 is formed by the notch 52.
- the lower plate 3 When the outsole 7 is grounded when the shoe is landed, the lower plate 3 is separated from the ground surface by the gap C 2 formed by the substantially V-shaped cut 5 2 formed on the inner surface of the connecting portion 5 (the inner surface in the shoe width direction). It is possible to avoid the upward load acting on the upper plate 2 from acting on the upper plate 2 as it is through the connecting portion 5, thereby reducing the push-up from the connecting portion 5 to the wearer's sole when the shoe is landed. In addition, the air gap C 2 can improve the cushioning property when landing on shoes, and can reduce the weight of the entire structure. Even in this case, the extension 5 a at the upper end of the connecting portion 5 is fixed to the side surface of the raised portion 20 of the upper plate 2, so that the connection between the connecting portion 5 and the winding portion 20 is secured. Strength can be secured.
- the portion 7a is provided at the rear end of the buttocks of the sole structure 1 and extends upward of the outsole 7a force toward the front of the shoe. It has an overhang 70 that projects into the gap 10.
- the extending portion 7 a force of the outsole 7 has a projecting portion 70 that projects into the space 10 toward the front of the shoe shoe, A bent portion 70 a extending while curving in a substantially U shape toward the rear end side of the flange portion is formed at the lower portion of the overhang portion 70. ing.
- the extending portion 7a of the outsole 7 has an overhanging portion 70 projecting into the gap 10 toward the front of the shoe.
- the projecting portion 70 is formed with a substantially V-shaped cut 7 Ob cut toward the rear end side of the collar portion.
- the overhanging portion 70 can secure a large adhesive surface between the extended portion 7 a of the outsole 7 and the upper plate 2.
- the upward load acting on the upper plate 2 from the ground plane through the lower plate 3 can be distributed by the overhang 70, so that from the ground plane on the rear end side. Can be eased.
- the curved portion 70a and the notch 7Ob can improve the cushioning property at the time of landing on the shoe.
- FIGS. 15 to 17 show sole structures according to other embodiments 5 to 5B of the present invention, and each figure shows a different embodiment.
- the same reference numerals as those in the first to fifth embodiments or the other embodiments 4 to 4D denote the same or corresponding parts.
- the extending portion 7a of the outsole 7 has an overhanging portion 70 projecting into the gap 10 toward the front of the shoe, A through hole 70 c that penetrates through the center of the rear end of the flange is formed below the overhang 70.
- the through hole 70 c has, for example, a circular cross section.
- a through-hole that penetrates through the center of the rear end of the buttocks below the projecting portion 70 extends to the left and right at the center of the rear end of the buttocks.
- the through hole 70 0 c is connected to the rear end of the flange portion below the overhang 70. 2 on the left and right sides of the center of the rear edge It is.
- the cushioning property is provided at the portion where the through hole is formed in the extended portion 7 a of the outsole 7.
- the first to fifth embodiments or the other stability at the time of landing can be secured.
- the entire shoe structure can be reduced in weight.
- the bonding surface between the extended portion 7a of the outsole 7 and the raised portion 20 of the upper plate 2 can be secured, the outsole extended portion 7a and the wound portion 20 Can be maintained.
- the number of through holes that penetrate the rear end of the flange portion may be three or more.
- the present invention is useful for a shoe sole structure, and is particularly suitable for those requiring cushioning properties, a smooth ride feeling, and lateral stability.
