Description

Shoes with improved heel fit performance

The present invention relates to a shoe with improved fitting performance according to the movement of the heel during exercise including walking and running, and particularly to a shoe with improved fitting performance according to the movement of the heel from the foot flat to the ground.

If the heel of the foot moves greatly inside the upper during walking or running, it becomes difficult to hold the foot stably during walking or running, or loss of force occurs. Therefore, the fitting performance that the heel fits the upper is an important function of the shoe.
There are many prior arts aimed at improving the fit of the heel (see Patent Documents 1 to 4).

JP2008-132227 (abstract) JP-A-2-5903 (abstract) US 4,670,998 (abstract) JP-A-6-217806 (abstract)

Patent Document 1 discloses an upper structure provided with an outer upper that wraps an upper main body. An expansion / contraction region is provided between the front portion and the collar portion of the upper body.
The upper body has a wide mouth when worn and shrinks the mouth while wearing, so a fit in the heel may be obtained.

Patent Document 2 discloses a hard stirrup covering the back and both sides of the rib. This hard stirrup is formed of a hard plastic containing reinforcing fibers.
Such a stirrup may help to prevent the scaphoid from rotating.

Patent Document 3 discloses a substantially V-shaped stirrup. This stirrup may inhibit midfoot support, especially inadvertent movement of the scaphoid bone.

Patent Document 4 discloses a shoe having a sock inner and a strap. In Patent Document 4, the sock inner is formed of a material that expands and contracts, and the strap may fit the soft sock inner to the heel.

However, in each of the above-mentioned documents, there is no disclosure of research on the movement of the toes of the foot from the foot flat to the takeoff during exercise.

Prior to the description of the configuration of the present invention, the movement of the heel will be described.
FIG. 16 shows an inner side view of the foot when standing, and FIG. 17 shows an inner side view when kicking out. In these figures, points O1 to O12 are markers attached to the surface of the foot, and the numerical values in the figures indicate the dimensions between the points in millimeters.

Comparing the standing position and the kicking position, the lower part of the foot heel (distance between point O3 and point O11, distance between point O3 and point O12) and rear part (distance between point O11 and point O12) It turns out that it shrinks centering on etc. This shrinkage of the heel will cause a gap between the upper and the foot.

Thus, while the heel of the foot shrinks about 3 mm toward the front, the heel of the upper surface of the sole will not shrink as much. Therefore, even if it is formed so that the rear end of the upper moves toward the rear end of the collar, the upper is restrained by the sole, so that the fit of the collar Performance will not improve as much.

That is, in order to prevent the kite from moving in the upper, it is presumed that it is important that the side of the upper is pressed against the upper side of the kite so that no deviation occurs between them.

The lower part of the upper body disclosed in Patent Document 1 is integrally connected to the sole from the front legs to the rear legs. Therefore, when the upper part having elasticity is contracted at the heel part of the upper body, the lower part not having elasticity may expand in the foot width direction. Therefore, the fit of the heel will be impaired.

The front portion of the star wrap disclosed in Patent Document 2 extends obliquely downward, and the star wrap does not cover the back of the heel. Therefore, a tensile force will act on the hard stirrup obliquely forward.
Thus, although the stirrup helps to control the rotation of the scaphoid bone, it will not help as much as the upper side of the upper fits the upper side of the heel below the heel.

Further, the stirrup is partially accommodated in the upper pocket, and is further disposed below the upper edge of the upper in the rear foot portion, and the upper edge portion of the upper that forms the mouth is placed on the foot. You won't be able to press it to the side.

The uppers disclosed in

Patent Documents

3 and 4 are integral with the sole from the front legs to the rear legs. For this reason, the tightening force of the shoe lace is less likely to concentrate on the mouth, the upper part near the mouth is less likely to follow the side of the foot, and the upper heel part is likely to spread in the width direction of the foot.

Therefore, an object of the present invention is to provide a shoe that can provide a fit feeling according to the movement of the heel from the foot flat to the takeoff during exercise including walking and running.

In order to achieve the above object, a shoe according to an aspect of the present invention is a shoe with improved heel fitting, which covers from the tip of the toe to the side of the heel and covers the toe, the inside and the outside of the foot, respectively. A main upper, a sub-up formed of a member different from the main upper, covering the heel and not covering the distal head of the metatarsal in the main upper, and a shoe race for fitting the main upper and the sub-upper to the foot And a sole to which a fixing edge of a lower edge of the main upper and the sub upper is fixed, the main upper being notched covered with a tongue piece, and arranged in two rows along the notch, the shoe A first eyelet hole through which the race passes, and the sub-upper includes portions covering the inner side surface and the outer side surface of the talar bone and the inner side surface, the outer side surface and the rear surface of the rib. The sub-upper has a lower part and an upper part above the lower part, and the lower part is covered with the main upper, the rear part of the tongue piece and the sub-upper. The upper part of the upper part forms a cuff where the legs rise upward when worn, and the upper part of the sub-upper is laminated with a cushion material that helps to fit the upper part of the foot. The laminated portion is bulged toward the surface of the foot by the cushion material, and the upper laminated portion extends obliquely upward from directly under the inner and outer heels to the rear, and Covering the lower part of the Achilles tendon at a level above the lower end of the heel, and the upper part has a front extension part extending forward from the front end of the rib toward the front from directly below the inner and outer heels, and the front extension part At least a part is covered with the upper, the upper part including the front extension part is not attached to the main upper, and the front extension part is provided with a eyelet part that forms a second eyelet hole. The eyelet portion passes through the inside and outside of the main upper, and a through hole that exposes the second eyelet hole to the outside of the main upper is formed, and the shoelace is formed by the plurality of first and first shoes. 2 In a state where the tightening force is exerted through the eyelet hole, the eyelet part is drawn to the center of the foot by the tightening force due to the shoelace part in the vicinity of the second eyelet hole, and the eyelet part penetrates the hole. The hole is bent by engaging with the main upper, whereby the direction of the tightening force is changed, and the upper part including the front extension part is pulled forward, and the Of the first eyelet holes, the main upper is attracted to the center of the foot by the tightening force by the shoelace part in the vicinity of the first eyelet hole behind the second eyelet hole and covers the main upper. The broken portion of the front extending portion is pressed against the upper side surface of the foot, and the laminated portion having the cushion material fits the upper side surface of the foot.

According to this aspect, since the sub-upper covers only the heel and is not fixed to the sole at the stepped portion, it easily follows the bending of the foot.

The sub-upper is a separate member from the main upper and covers the perimeter of the bag in the main upper. Therefore, even if the main upper spreads in the width direction of the foot in the footwear, the upper part of the sub-upper that is not attached to the main upper, especially the laminated part with the cushion material, fits the upper side of the foot with the tightening force of the shoelace That is not disturbed by the main upper.

In the through hole, the eyelet part is bent by engaging with the main upper, and the tightening force attracted to the center of the foot of the shoelace is changed to the forward pulling force. Therefore, forward tension acts on the upper side surface of the foot, particularly on the upper laminated portion of the sub upper, and the upper laminated portion of the sub upper fits on the side surface of the foot.

Furthermore, on the side surface of the talus, the main upper presses the front extension portion of the sub-upper from the outside toward the inside of the foot by the tightening force of the shoe race. As a result, the upper part of the sub-upper is curved along the planar cross section of the foot, and in particular the upper part of the sub-upper fits the upper side surface of the foot. In other words, the upper part of the sub-upper pulled forward through the eyelet part has a U-shaped cross section, but is curved toward the center of the foot as it goes forward from just below the heel by the pressing force of the main upper. It fits the upper side of the foot.

In the present invention, the laminated portion is not necessarily required.
However, when it has a lamination | stacking part, the lamination | stacking part which has a cushion material is easy to be pressed on the upper side surface of a leg | foot. Therefore, when it has a lamination part, fitting performance is high.
Further, the laminated portion may be laminated by adhering to one of the front and back surfaces of the fabric forming the sub-upper, or may be laminated by sandwiching the cushion material between the inner skin and the outer skin (fabric). Good.

In a preferred aspect of the present invention, the forward extension portion extends forward from the fixing edge portion of the sub-upper, and a front end of the fixing edge portion of the sub-upper is disposed rearward from a front end of the rib, The non-fixed edge of the lower edge of the extension extends obliquely rearward toward the front end of the fixed edge of the lower edge.

According to this aspect, the front end of the fixed edge portion of the lower edge is located behind the front end of the front extension portion, and when the front extension portion is pulled forward, the stacked portion is tensioned in the front-rear direction. Is not prevented from working. Therefore, it is easy to fit the laminated portion to the upper side surface of the foot.

In a preferred aspect of the present invention, the sub-upper has an exposed portion that is not accommodated in the main upper from directly below the rear ends of the inner and outer collars to the rear surface of the collar, and the main upper extends the lower part of the ribs from the rear surface. Covering.

According to this aspect, the main upper covers the lower part of the rib from the back, and the main upper has high stability performance for holding the rib. Therefore, the rigidity of the sub-upper can be reduced, and thus the fit of the sub-upper will be increased.
The exposed part exposed from the main upper of the sub-upper will not be deformed following the deformation of the main upper. Therefore, the upper part of the sub-upper will not expand in the width direction of the foot and will remain fitted to the upper side of the foot.

In a preferred aspect of the present invention, the main upper and the sub-upper are attached to each other behind the heel, and are not attached to each other at the upper part of the sub-upper just below the heel and in the front part thereof.

According to such an embodiment, the uppers are not attached to each other in the upper part directly under the heel. for that reason,
i) The main upper tends to spread in the width direction of the foot as the foot is bent, and its resistance during bending is small.
ii) Even if the main upper spreads in the mouth, the sub-upper is not restrained by the main upper, and therefore the sub-upper easily fits to the side of the foot.
iii) Moreover, both uppers are attached to each other on the back surface of the bag, and the rigidity of the back surface of the bag is large. Therefore, the stable performance of holding the heel is high.

In a preferred aspect of the present invention, the inner skin and the outer skin are formed of a flexible material so that the upper part of the sub-upper extends forward and backward when the shoelace is tightened.

According to this aspect, the sub-upper in which the flexible material is laminated on the cushion material is easily along the side of the foot without being restrained by the main upper.

In a preferred aspect of the present invention, the outer skin has a U-shaped synthetic resin that is harder than the laminated portion and has a U-shaped cross section so that the laminated portion is along the side surface of the foot below the upper edge of the sub-upper. The counter consisting of is fixed from the back of the bag to the inner and outer sides.

According to this aspect, the hard U-shaped counter does not interfere with the flexible cushioning material and the inner leg, and the hard counter helps the upper leg.

In a preferred aspect of the present invention, the front extending portion extends forward from the front end of the counter, and the main upper is moved by the tightening force of the shoelace at a portion ahead of the front end of the inner and outer counters. Press the front extension to the side of the foot.

According to this aspect, the front extension portion that is more flexible than the hard counter is pressed against the side of the foot by the main upper. Therefore, the front extension part curves along the surface of the instep. This bending dramatically increases the longitudinal tension acting on the laminated portion.

In a preferred aspect of the present invention, the counter is disposed along the laminated portion of the sub-upper, the upper edge of the main upper extends obliquely downward toward the rear end of the ridge toward the rear, and the main upper is the counter And the rear part of the counter is not covered at the upper part of the sub-upper.

According to this aspect, the main upper presses the front end of the counter against the side of the foot. Therefore, the moment acting on the counter is large, and even the hard counter can be pressed against the side of the foot.

As shown in these drawings, a fixing edge portion 1 a of the lower edge of the main upper 1 is sewn and fixed to an insole (insole) constituting a part of the sole 4, and the lower edge of the sub-upper 2. The fixed edge portion 2a is sewn and fixed.

Main upper 1:
As shown in FIG. 8, the main upper 1 has notches 10 covered with tongue pieces 5 and first eyelet holes h1 to h3, h5, h6 arranged in two rows along the notches 10 and through which the shoelace 3 passes. have.

As shown in FIGS. 1 and 3, the main upper 1 does not cover the lower end of the Achilles tendon T, and covers the lower part of the rib B9 from the back.
As shown in FIG. 8, a through hole 11 is formed inside and outside the main upper 1 in the middle foot region. As will be described later, an eyelet member (an example of an eyelet part) 24 having a second eyelet hole h <b> 4 provided in the sub-upper 2 is inserted into the through hole 11, and the second hole is inserted through the through hole 11. Eyelet holes h4 (FIG. 8) are exposed outside the main upper 2.

Sub-upper 2:
As shown in FIGS. 1 to 4, the sub-upper 2 has a lower part 2d and an upper part 2u above the lower part 2d, and the lower part 2d is covered with the main upper 1. The rear portion of the tongue piece 5 and the upper portion 2u of the sub-upper 2 form a mouth 6 from which the leg L rises when worn, and the foot 6 fits the foot.

As shown in FIGS. 2 and 4, the sub-upper 2 is in contact with the surface of the foot F on each side and back. The sub-upper 2 is formed so as to cover at least the ridge 8 behind the ridge M.

That is, as shown in FIG. 1, the sub-upper 2 covers at least a part of the inner surface of the talar bone B8, the scaphoid bone B6, and the rib B9 inside the foot F. On the other hand, as shown in FIG. 3, the sub-upper 2 covers at least a part of the outer surfaces of the talus B8, the cubic bone B7, and the rib B9 on the outside of the foot. Therefore, as shown in FIGS. 1 to 4, the sub-upper 2 is set so as to cover the heel 8 and not the metatarsal bone B4 _i .
Incidentally, B5 ₁ of FIG. 1 shows the medial cuneiform bone.

As shown in FIGS. 13A and 13B, the sub-upper 2 has laminated

portions

20 and 29 on the upper portion 2u and the lower portion 2d. Each

laminated portion

20, 29 is formed by laminating a cushion material 21 indicated by halftone dots, and an inner skin 22 and an outer skin 23 sandwiching the cushion material 21. The cushion material 21 may employ, for example, non-woven fabric (felt) in addition to a foam of resin or rubber, and the upper portion 2u and the lower portion 2d of the sub-upper 2 at the upper portion of the foot F (FIGS. 2 and 4). To help fit. The thickness of the cushion material 21 is such that the upper laminated portion 20 is thicker than the lower laminated portion 29, and the upper laminated portion 20 swells toward the surface of the foot F by the cushion material 21.

The inner skin 22 and the outer skin 23 shown in FIGS. 13A and 13B are formed of a flexible material so that the upper portion 2u of the sub-upper 2 extends slightly forward and backward when the shoelace 3 is tightened.
As a material for the inner skin 22 and the outer skin 23 of the sub-upper 2, for example, a cloth or a synthetic leather used for the tongue piece 5 can be used. The inner skin 22 and the outer skin 23 are formed of a flexible material that is easy to extend as compared with a portion covering the side of the foot of the main upper 1.

Counter 24;
As shown in FIG. 12A, a heel counter 25 made of a non-foamed synthetic resin having a U-shaped planar cross section is fixed to the outer skin 23. As shown in FIGS. 2, 4, and 5, the counter 25 is fixed to the surface of the outer skin 23. The counter 25 is fixed below the upper edge 2e of the sub-upper 2 so that the upper laminated portion 20 is along the side surface of the foot F. That is, the counter 25 is arranged along the stacked portion 20 of the sub-upper 2.

As shown in FIGS. 1, 3 and 9, the upper edge 1e of the main upper 1 extends obliquely downward to the rear end of the flange 8 (FIGS. 2 and 4).
The sub-upper 2 has an exposed portion 26 that is not accommodated in the main upper 1 from directly below the rear ends of the inner rod Mm and the outer rod Ml to the back surface of the rod 8.
Therefore, the main upper 1 covers the front end portion of the counter 25 at the upper portion 2u of the sub-upper 2, and covers the rear portion of the counter 25 at the upper portion 2u of the sub-upper 2, that is, at the exposed portion 26 of the sub-upper 2. Absent.

Forward extension 2f;
As shown in FIGS. 1 and 3, a front extending portion 2 f extending forward from the front end of the counter 25 is integrally formed on the upper portion 2 u of the sub-upper 2.
The front extending portion 2f extends forward from the front ends of both side surfaces of the rib B9 toward the front from directly below the inner and outer ribs Mm and Ml at the upper portion of the sub-upper 2.

The main upper 1 and the sub-upper 2 are bonded (attached) to each other at the lower part of the back of the flange 8 so as to be independently movable, and the winding portion 41 (upper and lower) of the sole 4 of the sub-upper 2 They are bonded (attached) to each other at the portion covered by the overlapping portion) and are not bonded (attached) to each other at the upper portion 2u of the sub-upper just below the heel M and the portion in front thereof. Therefore, the upper part 2u including the front extension part 2f is not attached to the main upper 1, and there is no possibility that the main upper 1 is deformed in connection with a change in the shape of the main upper 1. That is, even if the main upper 1 expands in the mouth, there is no possibility that the sub-upper 2 expands.

The front extension 2f extends forward from the fixed edge 2a of the sub-upper 2. On the other hand, the front end of the fixing edge portion 2a of the sub-upper 2 is disposed behind the front end of the rib B9. Therefore, the front extension portion 2f has a lower non-fixed edge portion 2b extending obliquely downward and rearward toward the front end of the fixed edge portion 2a of the lower edge. At least a part of the front extension 2f is covered with the upper 1.

Eyelet member 24;
A band-shaped eyelet member 24 different from the main upper 1 is fixed (sewn) to the inner and outer front extension 2f. By forming the eyelet member 24 of FIG. 8 in a loop shape, the eyelet member 24 is formed with a second eyelet hole h4 through which the shoelace 3 passes.

Tightening structure:
As shown in FIG. 8, in a state where the shoelace 3 is passed through the plurality of first and second eyelet holes h1 to h6 and exerts a tightening force, the shoelace 3 in the vicinity of the second eyelet hole h4 The eyelet member 24 is pulled toward the center of the foot by the tightening force of the region 30 (the region indicated by the halftone dots). At the same time, as shown in FIG. 10 and FIG. 11, the eyelet member 24 is bent by engaging with the main upper 1 in the through hole 11, thereby changing the direction of the tightening force, and FIG. The upper part 2u including the front extension 2f is pulled toward the front X (FIG. 10).

On the other hand, of the first eyelet holes h1 to h3, h5, and h6 shown in FIG. 8, the shoelace part 31 (part indicated by a halftone dot) near the first eyelet hole h5 behind the second eyelet hole h4. The main upper 1 is pulled toward the center of the foot by the tightening force. Accordingly, the portion of the front extension 2f covered by the main upper 1 shown in FIGS. 1 and 3 is pressed against the upper side surface of the foot F (FIGS. 2 and 4) in the direction of the arrow 100 in FIG. 12C. The laminated portion 20 that curves along the shape of the foot and has the cushion material 21 fits the upper side surface of the foot.

Therefore, as shown in FIGS. 14 and 15, the cushion material 21 fits to the upper side surface of the foot even when kicking out, and a feeling of fit can be obtained regardless of the movement of the heel 8.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily consider various changes and modifications within the obvious range by looking at the detailed description.
For example, as shown by a one-dot chain line in FIG. 2, the inner side of the sub-upper 2 may cover a part of the inner wedge bone B5 ₁ (FIG. 1) or the first metatarsal B4 ₁ (FIG. 1). A part may be covered.
On the other hand, the outer sub-upper 2, preferably from comfort point of view does not cover the fifth metatarsal B4 _5.
Further, instead of sewing the eyelet member 24 to the front extending portion 2f, the eyelet portion through which the shoelace 3 can be inserted is formed by forming an insertion hole using a resin or metal eyelet in the front extending portion 2f. May be.
A plurality of second eyelet holes h4 may be provided on the inside and / or outside of the foot.
Accordingly, such changes and modifications are to be construed as within the scope of the present invention as defined by the claims.

The present invention can be applied to shoes that can provide a fit according to the movement of the heel.
