Problems solved by technology

[0013] Depend on Figure 17 It can be seen that in the case of shoes with high bending resistance, the energy loss is larger from the middle between (b) and (c) to (d) in the first half of the kick-out phase, and in the case of shoes with lower bending resistance In the case of the shoes, the energy loss is large in (e) to (f) in the second half of the kick-out stage

Embodiment 1

[0125] Figure 1A to Figure 7C The shoe sole structure of the first embodiment of the present invention is shown. Such as Figure 1A and Figure 1B As shown, the sole structure 1 includes: an upper midsole 2 made of a soft elastic member, which extends from the heel H of the shoe to the forefoot F through the midfoot M in the front-rear direction; the hard elastic member The upper plate 3 is fixed on the lower part of the upper middle sole 2, and extends from the heel H of the shoe to the forefoot F through the middle foot M in the front-rear direction; the lower middle sole made of soft elastic member 4. The lower midsole 4 is fixedly connected to the lower part of the upper plate 3, and is mainly arranged on the forefoot part F of the shoe; and the lower plate 5 made of a hard elastic member, which is mainly from the heel part H of the shoe to the center The foot M extends in the front-rear direction, and its front end is fixed to the lower part of the sole 4 in the lower...

Embodiment 2

[0191]In the above-mentioned first embodiment, the case where the groove 41 formed in the sole 4 in the lower part has an inverted V-shaped cross-sectional shape was described as an example, but the application of the present invention is not limited thereto. The cross-sectional shape of the groove 41 can also be an inverted U shape or an arc shape (ie, a flat inverted U shape). As the groove 41 , any shape other than the above can be adopted as long as it is a groove shape opening downward.

[0192] In addition, regardless of the cross-sectional shape of the groove 41, the bending restricting member 10 arranged in the groove 41 is bent upward because of the upper curved portion 10a bent upward in the groove 41, and the upper curved portion 10a is not fixed. on the bottom wall of the groove 41. In addition, ideally, the bending limiting member 10 is far away from the wall surface of the groove 41 and is not fixed to the wall surface of the groove 41 .

Embodiment 3

[0194] In the above-mentioned first embodiment, the case where the cross-sectional shape of the bending restricting member 10 in the front-rear direction of the sole was described as an example was described, but the cross-sectional shape of the bending restricting member 10 may be in an inverted U-shape. Or arc-shaped (that is, flat inverted U-shaped). In addition, various shapes can be adopted according to the cross-sectional shape of the groove 41 of the lower middle sole 4 and the like.

[0195] In addition, as bending limiting members such as Figure 8 As shown, there may be a lower curved portion 10'a bent downward in a V-shape or a U-shape. In this case, the elastic cover member 8' covering the lower curved portion 10'a of the bend restricting member 10' from below may also have a curved shape along the curved shape of the bend restricting member 10'. In addition, in Figure 8 In , the same symbols as those in the above-mentioned embodiments represent the same or cor...

Abstract

Disclosed is a sole structure which can reduce energy loss while running. A sole structure (1) for a shoe is provided with: an upper plate (3) which is disposed in the upper part of the sole structure (1) and which stretches from the front to the back of the sole; a lower mid-sole (4) which is made from a soft elastic member, is disposed below the upper plate (3), is fixed to the lower surface of the upper plate (3), and has a groove (41) which opens downwards and which stretches in the width direction of the sole; and bend restriction sections (10) which are provided in a bent state in the length direction of the sole between edge sections of the opening of the groove (41), and which connect the edge sections of the opening. When the sole starts bending, the bend restriction sections (10) allow the sole to bend from when the bend restriction sections (10) are in a bent state up until the bend restriction sections (10) are gradually stretched into a straight line between the edge sections of the opening, and when the sole has been bent, the bend restriction sections (10) restrict the bending of the sole by receiving force in the extension direction when the straight line is stretched between the edge sections of the opening.

Description

technical field [0001] The present invention relates to a sole structure for shoes, and specifically relates to an improvement of a structure for reducing energy loss during running. Background technique [0002] The applicant of the present invention proposed, for example, a sole structure as shown in International Publication No. 2006 / 070549 pamphlet in order to improve the flexibility of the forefoot portion of the sole of the shoe. The sole structure has: an upper plate disposed on the upper side of the forefoot region of the sole structure and extending in the front-rear direction along the forefoot region; and a lower plate separated from the upper plate. It is arranged under the upper plate with a certain gap, extends in the front-rear direction along the forefoot region, and has such irregularities that the path length in the front-rear direction is longer than the path length in the front-rear direction of the upper plate. shape. [0003] In this case, since the l...
