Description

Shoes with stabilizer

The present invention relates to a shoe having a stabilizer.

As a stabilizer for a hind foot, a heel counter for stabilizing a heel during running or walking is well known.
Further, as a stabilizer for the forefoot, a hoisting structure that suppresses the lateral swing in and out of the front foot during running or walking is well known.

JP09-215501A (FIGS. 6 and 3) JP10-108709A (front page) JP2002-262907A (front page) JP60-135033A (FIG5) JP07-8304A (Fig. 1) WO2013 / 168256A1 (Summary) JP2003-9906A (Fig. 3)

The stabilizer restrains the lateral shake while restraining the foot. Therefore, it becomes a factor which a feeling of wear falls.
Accordingly, an object of the present invention is to provide a shoe having a stabilizer that can suppress lateral runout of the foot while preventing a feeling of wearing from being lowered.

For example, JP60-13503A discloses a U-shaped counter that covers the side surface and the back surface of the rear leg portion of the midsole. The counter will suppress the hind-limb swing. However, the counter covering the side and back of the hind leg of the midsole will inhibit the deformation of the midsole. Therefore, the cushion performance of the hind leg portion is reduced, and the wearer may easily feel a large impact of fast strike when landing on running or walking.

For example, JP07-8304A discloses a rising portion of a non-foamed rigid reinforcing member. This start-up will suppress forefoot sideways. However, the raised portion of the non-foamed rigid reinforcing member will significantly inhibit the midsole's forefoot from bending and deforming. Therefore, the wearer may easily feel resistance for bending during running or walking.

In the first aspect, the present invention is a shoe having an upper 7 and a stabilizer attached to at least a part of the upper 7,
The stabilizer includes a midsole 1 and a counter 6 disposed on a rear foot portion 5R of the midsole 1,
The counter 6 includes a counter main body 60 attached to the surface of the upper foot portion 5R of the upper, a downward extending from the counter main body 60, and an inner ME of the rear foot portion 5R of the midsole 1. And / or at least one

skirt

6M, 6L that covers the side surface SF of the outer side LA and is attached to the side surface SF,
The at least one

skirt

6M, 6L has a rear end 6E disposed on the side surface SF or the back surface BF of the midsole 1, and at least a part of the back surface BF of the midsole 1 in the circumferential direction includes the rear end 6E. The

skirts

6M and 6L are provided with exposed portions that are exposed without being arranged.

In the first aspect, the skirt integrated with the counter body increases the rigidity of the counter. Further, the skirt is attached to the midsole and covers the side surface of the midsole, thereby further increasing the rigidity of the counter and suppressing the deformation of the midsole. Therefore, the lateral runout suppressing function of the rear foot is remarkably improved on the inside and / or outside where the skirt is provided.

On the other hand, the exposed portion of the back of the midsole where the skirt is not attached can exhibit the cushioning performance inherent to the midsole. Therefore, the impact of fast strike that occurs when landing from the rear end of the rear foot during running or walking is buffered by the rear end of the midsole.

In the first aspect, “extending downward from the counter body 60” means that the skirt is formed integrally with the counter body.
Further, “arranged on the side surface SF or the back surface BF” means that the rear end is disposed on a side surface extending rearward linearly, on the back surface, or on a corner connecting the inner and outer side surfaces and the back surface.
The “rear surface” means a central portion that is about 1/3 of the maximum width of the rear leg portion of the midsole among the surfaces that can be seen from behind.

In the first aspect, it is sufficient that at least a part of the back surface BF of the midsole 1 is exposed without being covered with the skirt, and for example, the skirt may extend to the center of the back surface. This is because the impact of the fast strike is often greater outside the center of the hind legs.

In a second aspect, the present invention includes a stabilizer having an outsole 2 having a ground contact surface that contacts the road surface, and a midsole 1 disposed on the outsole 2 and covering at least a part of a wearer's front foot. Shoes,
The midsole 1 is:
A main midsole 4 formed of a resin foam and at least one

sub-midsole

3M, 3L disposed on the main midsole 4 and formed of a resin foam;
The hardness of the at least one

secondary midsole

3M, 3L is greater than the hardness of the main midsole 4,
The at least one

secondary midsole

3M, 3L includes a base 30 that covers a back surface of a wearer's mother toe B1 and / or gavel B5 in the inner ME and / or the outer LA of the forefoot 5F, and the inner ME or the outer In the LA and at positions separated from each other in the front-rear direction, two hard winding

upper portions

31 and 32 that are connected to the base 30 and wind upward from the base 30 are provided.

In the second phase, the auxiliary midsole that is harder than the main midsole 4 forms two hard

upper portions

31 and 32 that are separated from each other in the front foot 5F. These two hard-winding

upper portions

31 and 32 are unlikely to fall down, and can prevent lateral shaking of the forefoot portion 5F in a wide region spaced from each other in the front-rear direction of the forefoot portion 5F.

The relatively hard two hard winding

upper portions

31 and 32 are separated from each other in the front-rear direction, and therefore, the side surface of the midsole 1 is easily bent between the two hard winding

upper portions

31 and 32. In particular, the sub-midsole including the two hard winding upper portions is formed of a resin foam unlike the hard resin non-foaming material. Therefore, the base 30 and the two hard winding

upper portions

31 and 32 are also appropriately bent. easy. Therefore, it will be difficult to feel resistance for bending when running or walking.

In addition, the flexible midsole 1 tends to be deteriorated because the foam structure is fatigued and the rigidity of the forefoot becomes weaker with time as the flex midsole 1 is repeatedly bent. In contrast, a stiff secondary midsole will suppress the degradation of rigidity.

In the present specification, the hardness difference due to C hardness between the main midsole and the sub midsole is preferably about 3 to 25 degrees, more preferably about 4 to 20 degrees. If the hardness difference is small, it is difficult to obtain the effect. On the other hand, if the hardness difference is too large, it is likely to be out of the practical hardness range.

From this point of view, the hardness of the sub midsole is, for example, JIS C hardness, set to about 59 to 72 degrees, and more preferably set to about 61 to 69 degrees.
On the other hand, the hardness of the main midsole is, for example, JIS C hardness set to about 47 degrees to 62 degrees, and preferably about 49 degrees to 57 degrees.
In the present specification, the C hardness means a value measured by a C-type hardness meter of JIS K 7312.

Hereinafter, preferred embodiments of the first aspect will be described.
In the first aspect, preferably, at least one

skirt

6M, 6L is connected to the wide portion 6W attached to the inner side ME and / or the side surface SF of the outer side LA of the rear foot portion 5R of the midsole 1, and the wide portion 6W. In addition, the side face SF and / or the back face BF of the midsole 1 includes a first width small portion 61 having a height width H covering the midsole 1 smaller than that of the wide portion 6W.

The width H in the height direction of the skirt is smaller than that of the wide portion 6W in the first width small portion 61. The first small width portion 61 having a small width H will exhibit the function of suppressing the lateral vibration of the rear foot and the cushion performance at the rear end of the rear foot.

More preferably, in the first aspect, the lower end line 61L of the first small width portion 61 of the

skirts

6M and 6L is formed on the inner side ME of the rear foot portion 5R of the midsole 1 and / or the side surface SF of the outer side LA and / or the midsole 1. The rear surface BF extends obliquely upward from the rear D2.

In this case, since the width H of the first small width portion 61 becomes smaller toward the back BF, the function of suppressing the lateral vibration of the rear foot and the cushion performance will change smoothly.
Further, the first small width portion 61 is smoothly connected to both the wide portion 6W and the counter main body 60, which will help to increase the rigidity of the wide portion 6W. Therefore, the function of suppressing lateral vibration will be improved.

More preferably, in the first aspect, a second width small portion 62 that is continuous with the wide portion 6W and has a width H in the height direction that covers the midsole 1 at a portion extending from the wide portion 6W to the front D1 is smaller than that of the wide portion 6W. At least one

skirt

6M, 6L.

The skirt has a width H in the height direction smaller than that of the wide portion 6 W in the second width small portion 62. The second small width portion 62 having a small width H will exhibit a function of suppressing lateral vibration and cushion performance at a portion ahead of the wide portion 6W.

More preferably, in the first aspect, the line 62L at the lower end of the second small width portion 62 of at least one of the

skirts

6M and 6L extends obliquely above the front D1 on the side surface SF of the inner ME and / or the outer LA.

In this case, since the width H of the second small width portion 62 decreases toward the front D1, the function of suppressing the lateral vibration and the cushion performance will change smoothly.
Further, the second small width portion 62 is smoothly connected to both the wide portion 6W and the counter main body 60, which will help to increase the rigidity of the wide portion 6W. Therefore, the function of suppressing lateral vibration will be improved.

In the first aspect, preferably, the counter 6 further includes a flange 6F that is connected to the counter body 60 and protrudes from the counter body 60 toward the center CE of the rear foot 5R.

In this way, the flange 6F protruding toward the center CE of the rear foot portion 5R is useful for supporting the sole.
Here, the center CE is a concept wider than the center, and means a region between the inner side and the outer side and between the rear end of the middle foot part and the rear end of the rear foot part.

In addition, a forefoot part, a middle leg part, and a hind leg part mean the site | part which covers the front leg, middle leg, and hind leg of a leg, respectively. The forefoot consists of 5 metatarsals and 14 ribs. The metatarsal consists of a scaphoid bone, a cubic bone and three wedge bones. The hind leg is a part behind the middle leg.

More preferably, in the first aspect, the flange 6F is formed in a U shape in plan view.

The U-shaped flange 6 F suppresses deformation so that the two front ends of the counter 6 are expanded, so that the rigidity of the counter 6 is remarkably increased. Accordingly, the hind-rolling prevention function of the hind legs is significantly improved.
Further, the U-shaped flange 6F does not support the center CE of the hind legs, and therefore there is no possibility that the cushion performance of the hind legs will deteriorate.

More preferably, in the first aspect, a step 11 to which the flange 6F is fitted is formed on the upper surface 1U of the midsole 1.

In this case, the flange 6F of the counter 6 is adapted to the stepped portion, and the flange 6F is smoothly connected to the upper surface of the sole 1. Therefore, there is no possibility that the flange 6F makes the sole feel uncomfortable.

Preferably, in the first aspect, the counter main body 60 covers from the inner side surface of the upper rear leg portion 5R to the outer side surface through the back surface BF, and is formed in a U shape in plan view.

The U-shaped counter main body 60 supports the rear foot via the upper, and therefore suppresses lateral shaking of the rear foot.

In the first aspect, the

skirts

6M and 6L may be provided on at least the inner ME of the inner ME and the outer LA.

Such an inner ME skirt 6M will suppress compression deformation of the inner midsole of the hind foot, and thus contribute to suppression of over pronation.

Here, “the skirt is provided at least on the inner side ME” means that the skirt may cover a part of the outer side surface or the back surface.
The skirt may be provided only on the inner side of the inner side and the outer side. In this case, the skirt may exist on the back surface but is not provided on the outside.

In the first aspect, the skirt may be provided on at least the outer LA of the inner ME and the outer LA.

Such a skirt 6L on the outer side LA suppresses the compressive deformation of the outer midsole of the rear foot part, and therefore, will contribute to the suppression of overload.

Here, “the skirt is provided at least on the outer side LA” means that the skirt may cover a part of the inner side surface or the back surface.
The skirt may be provided only on the outer side of the inner side and the outer side. In this case, the skirt may exist on the back surface, but is not provided on the inside.

In the first aspect, the skirt may be provided on both the inner side ME and the outer side LA.

Such inner and

outer skirts

6M, 6L will help to suppress both overtime and overtime.
In this case, the skirt may cover a part of the back surface.
The area of the inner skirt may be larger than that of the outer skirt. Alternatively, the area of the outer skirt may be larger than that of the inner skirt. Alternatively, the two skirts may be the same size.

Hereinafter, preferred embodiments of the second aspect will be described.

In the second aspect, preferably, the main midsole 4 defines a fitting recess 43 into which the base 30 of at least one sub-midsole 3M, 3L fits.

By fitting the sub-midsole into the fitting recess 43, the sub-midsole and the hard winding

upper portions

31 and 32 are accurately positioned with respect to the main midsole 4.

More preferably in the first aspect, the main midsole 4 further includes a softly wound upper portion 42 that is disposed between the two hard wound

upper portions

31 and 32 and that is connected to the base 40 of the main midsole 4 and winds up from the base 40. .

The softly wound upper part 42 is disposed between the hardly wound

upper parts

31 and 32 that are separated from each other in the front-rear direction, and therefore strengthens the portion where the lateral vibration suppression function between the two hardly wound

upper parts

31 and 32 is weak. Accordingly, the lateral shake suppression function is further enhanced.
On the other hand, the softly wound upper part 42 of the main midsole 4 is smaller in hardness than the two hardly wound

upper parts

31 and 32. Therefore, it will be hard to feel the resistance for bending by suppressing the adverse effect that the midsole is difficult to bend.

Preferably, in the second aspect, the main midsole 4 includes a protrusion 41 that is surrounded by the fitting recess 43 and the softly wound upper part 42 and continues to the softly wound upper part 42.

The main midsole 4 is disposed under the base 30 of the sub-midsole. Therefore, a portion corresponding to the base 30 of the sub-midsole has a small thickness. When the soft-winding upper part 42 is wound up from such a small thickness part, the soft-winding upper part 42 is likely to fall down, and a sufficient lateral shake prevention function may not be exhibited.
On the other hand, the protrusion 41 connected to the soft-winding upper part 42 suppresses the falling of the soft-winding upper part 42, and therefore, a high side-shake prevention function can be expected.

In the second aspect, the sub-midsole 3M, 3L preferably defines a notch 33 constricted at the protrusion 41.

Such a notch 33 in the secondary midsole helps the midsole bend at the intended site.

In the second aspect, preferably, at least the outer LA is provided with a sub-midsole 3L, and the sub-midsole 3L of the outer LA is provided with two hard winding

upper portions

31 and 32.

In general, the lateral vibration of the forefoot is likely to occur outside the foot, and the lateral vibration can be suppressed.
A secondary midsole 3M having two hard winding

upper portions

31 and 32 may be provided at least on the inner side ME.

In the second aspect, more preferably, the front end 31E of the front hard winding upper portion 31 is disposed in front D1 of the small curb ball O5 and the rear hard winding upper portion 32 of the two hard winding

upper portions

31 and 32. The rear end 32E is disposed rearward D2 with respect to the small ball O5.

The bending of the outer side of the foot is generally large in the vicinity of the small ball O5, so that the midsole 1 is also bent in the vicinity of the small ball O5. The placement of the two hard-wound

upper portions

31, 32 in the outer LA will facilitate proper bending of the outer side of the foot.

Preferably, in the second aspect, the sub-midsole includes a pair of sub-midsoles 3M, 3L of an inner ME and an outer LA, and the pair of sub-midsoles 3M, 3L are both provided with two hard

upper portions

31, 32 is provided.

In this case, the lateral shake prevention function and the like can be improved on the inside and outside of the front foot.

More preferably, in the second aspect, the front end 31E of the front hard winding upper portion 31 among the two inner hard winding

upper portions

31 and 32 is disposed in front D1 of the main ball O1, and the rear D2 hard winding. The rear end 32E of the upper part 32 is disposed at the rear D2 with respect to the main ball O1,
Of the two hard winding

upper portions

31, 32 of the outer side LA, the front end 31E of the hard winding upper portion 31 of the front D1 is disposed in front D1 of the small ball O5, and the rear end 32E of the rear hard winding upper portion 32 is It arrange | positions from the small ball O5 back D2.

The bends on the inside and outside of the foot are generally large in the vicinity of the main ball O1 and the small ball O5, so that the midsole 1 is also bent in the vicinity of the main ball O1 and the small ball O5. The placement of the two hard

upper portions

31, 32 in the inner ME and the outer LA will facilitate proper bending of the foot inside and outside.

Preferably in the second aspect, the secondary midsole includes a pair of

secondary midsole

3M, 3L of the inner ME and the outer LA,
A pair of

sub midsole

3M, 3L is mutually spaced apart and arrange | positioned by inner side ME and outer side LA.

In this case, the lateral shake prevention function and the like can be improved on the inside and outside of the front foot. Further, since the pair of sub-midsoles are separated from each other inside and outside, even if the hardness of the sub-midsole is large, problems such as difficulty in bending are unlikely to occur.
