Description

shoes

The present invention relates to shoes.

Shoes that can easily tighten the upper are known. For example, Patent Document 1 describes a shoe having a shoelace for tightening the upper and a fastener provided in the middle of the shoelace. This shoelace passes through the through holes formed on both sides of the opening of the upper in a zigzag manner, and the end is fixed to the upper. The fastener is fixed near the opening on the upper part of the upper.

U.S. Pat. No. 9,730,492 U.S. Pat. No. 5,353,483 Japanese Unexamined Patent Publication No. 10-179210 Special Publication No. 2018-532554 Japanese Patent No. 6236142 Japanese Patent No. 6117380

The present inventors have obtained the following recognition regarding the tightening mechanism and fit of the upper.
It is desirable that the upper can be easily tightened in order to shorten the time for putting on and taking off shoes. However, in the shoes described in Patent Document 1, since the fastener is fixed in the vicinity of the opening of the upper portion, the tightening force is concentrated in the vicinity of the opening, and the tightening force decreases from the opening to the toe. The gap between the upper and the instep becomes large and the fit deteriorates.

In order to improve the fit on the toe side, it is conceivable to tighten the entire shoelace strongly, but in this case, the tightening force near the shoe opening becomes excessively large, which is disadvantageous from the viewpoint of comfort. From these, the present inventor has recognized that the shoes described in Patent Document 1 have room for improvement from the viewpoint of both facilitating the tightening of the upper and maintaining the fit.

The present invention has been made in view of these problems, and an object of the present invention is to provide shoes capable of maintaining fit while facilitating tightening of the upper.

In order to solve the above problems, a shoe according to an embodiment of the present invention includes a sole, an upper provided above the sole to accommodate the foot, a tightening portion for applying a tightening force to the upper, and a tightening portion. It is provided with a force transmission unit for transmitting the tightening force to the lower portion of the upper midfoot portion.

FIG. 1 shows a state in which the fastener 36 is not fixed to the upper 20, and FIGS. 2 and 3 show a state in which the fastener 36 is fixed to the upper 20.

(Tightening part)
The tightening portion 30 tightens the upper 20. The tightening portion 30 of this example is arranged so as to straddle the central opening 20c in the width direction. The tightening portion 30 applies a tightening force to the upper 20 so as to close the central opening 20c in the width direction. The tightening portion 30 may include a band-shaped member, a string-shaped member, a band-shaped member, and a string-shaped member. The tightening portion 30 of the present embodiment is a shoelace 30s and includes a first portion 32 and a second portion 34 that are continuous with each other. The first portion 32 is a portion of the shoelace 30s that extends from the boundary with the second portion 34 or from 30b to the end portion 32e. The second portion 34 is a portion of the shoelace 30s from the boundary 30b with the first portion 32 to the end portion 34e. The boundary 30b and the

ends

32e and 34e will be described later.

The stringing portion 28 passes the first portion 32 or the second portion 34 and transmits the tightening force of the tightening portion 30 to the upper 20. The stringing portion 28 of this example is an eyelet having holes that penetrate vertically. The stringing portion 28 is formed in the stringing forming portion 26 provided on the peripheral edge of the central opening 20c of the upper 20. The stringing forming portion 26 includes a first forming portion 26a provided on the inner foot portion 22 and a second forming portion 26b provided on the outer foot portion 24. The stringing forming portion 26 is formed of a material having a lower elasticity than the surroundings, a material thicker than the surroundings, a material having a density higher than the surroundings, or a material harder than the surroundings, in order to increase the rigidity more than the surroundings. It may be made of the same material as the surroundings.

The stringing portion 28 of the present embodiment has an outer stringing portion 28e provided on the outer leg side and an inner stringing portion 28j provided on the inner leg side. A plurality of inner stringing portions 28j are provided in the first forming portion 26a, and a plurality of outer stringing portions 28e are provided in the second forming portion 26b. From the viewpoint of flattening the distribution of the tightening force in the front-rear direction, the number of inner stringing portions 28j (for example, 5) is larger than the number of outer stringing portions 28e (for example, 4). The number of the inner stringing portions 28j is an odd number, the number of the outer stringing portions 28e is an even number, and the sum of these is an odd number. That is, the outer stringing portion 28e and the inner stringing portion 28j are arranged asymmetrically in the width direction.

(Fastener)
The fastener 36 is a member for detachably fixing the tightening portion 30 to the lower portion of the middle foot portion 20 m of the upper 20, and corresponds to a force transmission portion. The fastener 36 is fixed to the upper 20 by being connected to the receiving portion 38 provided on the upper 20. That is, the fastener 36 has a fixed state connected to the receiving portion 38 and a non-fixed state separated from the receiving portion 38. When the fastener 36 is fixed, it is preferable that the fastener 36 is fixed near the boundary portion 20h of the upper 20 with the sole 10 on the outer foot side of the midfoot portion 20 m, but the receiving portion 38 is fixed to the upper 20 in the upper view. It suffices if it is fixed on or below the line that constitutes the contour of. The receiving portion 38 may be fixed to the side surface of the sole 10. The contour of the upper 20 is a line connecting the most outwardly protruding portions of the upper 20. The fastener 36 may be any as long as it can fix the tightening portion 30, and may be, for example, a hook-and-loop fastener, a hook, a magnet, or the like. The fastener 36 in this example is a male part of the resin buckle, and the receiving portion 38 is a female part of the buckle. The fastener 36 and the receiving portion 38 may be a front release type buckle or a side release type buckle.

(Position adjustment mechanism)
Since the shape of the foot varies from wearer to wearer, it is desirable that the fixed position of the fastener 36 be adjustable. Therefore, this embodiment has a position adjusting mechanism 42 capable of moving the fixed position of the fastener 36 in the upper 20 in the front-rear direction. As an example, the position adjusting mechanism 42 may be a slider mechanism. The position adjusting mechanism 42 of the present embodiment includes a rail member 42b provided on the outer leg portion 24 of the upper 20 and extending in the front-rear direction, and a slider 42s provided with the rail member 42b slidable back and forth. A receiving portion 38 is fixed to the slider 42s. The position adjusting mechanism is not essential, and the position of the receiving portion 38 may be fixed.

The tongue 70 covers the central opening 20c on the internal space 20a side of the upper 20. As the tongue 70, a so-called split tongue in which the widthwise ends are fixed to the left and right ends of the central opening 20c and the central portion of the tongue 70 is divided into left and right can also be adopted.

See also FIG. FIG. 4 is a plan view showing the periphery of the tightening portion 30. This figure shows a part of the fastener 36 cut out. The plurality of inner string threading portions 28j are referred to as threading portions 28j1, 28j2, 28j3, 28j4, and 28j5 in order from the front to the rear. Further, the plurality of outer string threading portions 28e are referred to as threading portions 28e1, 28e2, 28e3, 28e4 in order from the front to the rear. The through portions 28j1, 28j2, 28j3, 28j4, and 28j5 may be arranged at equal intervals or may be partially arranged at irregular intervals. Further, the through portions 28e1, 28e2, 28e3 and 28e4 may be arranged at equal intervals or may be partially arranged at unequal intervals.

The through portion 28j3 arranged at the center of the inner string through portion 28j in the front-rear direction is particularly referred to as the central through portion 28j3. The portion of the tightening portion 30 that passes through the central through portion 28j3 is defined as the boundary 30b between the first portion 32 and the second portion 34. Of the tightening portions 30, the portion connected to the rear side from the central through portion 28j3 is referred to as the first portion 32. Further, of the tightening portion 30, the portion connected to the front side from the central through portion 28j3 is referred to as the second portion 34. That is, the first portion 32 and the second portion 34 have a relationship in which one becomes longer and the other becomes shorter, and the position of the boundary 30b in the total length of the tightening portion 30 changes accordingly.

The end portion 32e of the first portion 32 and the end portion 34e of the second portion 34 are fixed to the outer leg side of the upper 20. In this example, the end portion 32e of the first portion 32 is fixed to the second through portion 28e2 from the front of the outer string threading portion 28e. Further, the end portion 34e of the second portion 34 is fixed to the fourth through portion 28e4 from the front (first from the rear) of the outer string threading portion 28e. Here, the fact that the end portion is fixed means that even if the fastener 36 is pulled, the end portion is held without coming off from the through portion. The fixed structure of the

ends

32e and 34e is not limited, but in this example, the

ends

32e and 34e are formed with a knot (hump) having a size that does not allow the through portion 28e to pass through. The ends 32e and 34e may be configured by using a stringing member.

As shown in FIG. 1, the portions of the shoelace 30s extending from the knots of the

ends

32e and 34e to the opposite side of the through portion 28e are referred to as

extension cord portions

32j and 34j. The tips of the

extension string portions

32j and 34j may be free ends. The tips of the

extension string portions

32j and 34j may be cut to an appropriate length according to the wearer.

Since the shape of the foot is different for each wearer, the appropriate lengths of the first part 32 and the second part 34 are also different. Therefore, it is desirable that the lengths of the first portion 32 and the second portion 34 can be changed. Therefore, in the present embodiment, the lengths of the first portion 32 and the second portion 34 are configured to be adjustable at the end portion 32e of the first portion 32 and the end portion 34e of the second portion 34.

If the position of the knot of the end portion 32e is changed and the extension string portion 32j is lengthened, the first portion 32 becomes shorter, and if the extension string portion 32j is shortened, the first portion 32 becomes longer. When the position of the knot of the end portion 34e is changed and the extension string portion 34j is lengthened, the second portion 34 becomes shorter, and when the extension string portion 34j is shortened, the second portion 34 becomes longer. As mentioned above, the tip side of the knot may be cut to an appropriate length. Further, instead of forming a knot, for example, a dial-type length adjusting mechanism may be provided. In these cases, the length can be easily adjusted.

The route from the end 32e of the first part 32 will be described. As shown in FIG. 4, the first portion 32 extends from the through portion 28e4 to the through portion 28j5, from the through portion 28j5 to the through portion 28j1, from the through portion 28j1 to the through portion 28e1, and from the through portion 28e1 to the central through. It extends to part 28j3. Of the first portion 32, the portion from the through portion 28j5 to the through portion 28j1 is pulled out inward to form the lead portion 32p. A fastener 36 is provided on the lead portion 32p. In addition, each portion extending between the inner stringing portion 28j and the outer stringing portion 28e of the first portion 32 is referred to as an inner / outer stretching portion 32k.

The route from the end 34e of the second part 34 will be described. As shown in FIG. 4, the second portion 34 extends from the through portion 28e2 to the through portion 28j2, from the through portion 28j2 to the through portion 28j4, from the through portion 28j4 to the through portion 28e3, and from the through portion 28e3 to the center through. It extends to part 28j3. Of the second portion 34, the portion from the through portion 28j2 to the through portion 28j4 is pulled out inward to form the lead portion 34p. A fastener 36 is provided on the lead portion 34p. In addition, each portion extending between the inner stringing portion 28j and the outer stringing portion 28e of the second portion 34 is referred to as an inner / outer extending portion 34k.

The

lead portions

32p and 34p in this example pass through the passage in the fastener 36. Therefore, by pulling the fastener 36, tension can be applied to the first portion 32 and the second portion 34, and a tightening force can be applied to the upper 20.

The fastener 36 is arranged in each of the first portion 32 and the second portion 34. The fastener 36 is attached so as to be movable relative to the first portion 32 and the second portion 34. Therefore, by changing the positional relationship between the boundary 30b of the first portion 32 and the second portion 34 and the fastener 36, one of the first portion 32 and the second portion 34 is shortened to increase the tightening force, and the other is shortened. It can be lengthened to weaken its tightening force.

The first portion 32 and the second portion 34 are divided into

front portions

32f and 34f arranged in front of the fastener 36 and

rear portions

32b and 34b arranged in the rear, respectively. That is, the fastener 36 is arranged between the

front portions

32f and 34f and the

rear portions

32b and 34b. By changing the positional relationship of the fastener 36 with the shoelace 30s, one of the

front portions

32f and 34f and the

rear portions

32b and 34b can be weakened and the other tightening force can be increased. Thereby, the distribution of the tightening force in the front-rear direction can be adjusted.

See also FIG. FIG. 5 is a plan view showing the positional relationship between the shoelace 30s, the wearer's ball and the small toe. In this figure, the straight line connecting the small toe ball portion and the mother toe ball portion of the wearer is indicated by a reference numeral Lb. The straight line Lb is inclined clockwise by 15 ° in a plan view with respect to the width direction.

In the present embodiment, the rearmost portion of the first portion 32 constitutes the top line 30h of the tightening portion 30, and the frontmost portion of the first portion 32 constitutes the bottom line 30j of the tightening portion 30. In the example of FIG. 4, the top line 30h and the bottom line 30j are located on the outer foot side behind the inner foot side. In a plan view, the top line 30h and the bottom line 30j are inclined by a predetermined angle θn with respect to the width direction. The predetermined angle θn may be an angle (for example, 15 °) that approximates the positional relationship between the wearer's ball and the small toe in a plan view.

Further, the positional relationship between the through portion 28j5 and the through portion 28e4 through which the top line 30h passes is close to the positional relationship between the wearer's ball and small toe. That is, the straight line connecting the through portion 28j5 and the through portion 28e4 extends substantially parallel to the straight line connecting the ball portion of the mother toe and the ball portion of the small toe. Further, the positional relationship between the through portion 28j1 and the through portion 28e1 through which the bottom line 30j passes is close to the positional relationship between the wearer's ball portion and the small toe ball portion. That is, the straight line connecting the through portion 28j1 and the through portion 28e1 extends substantially parallel to the straight line connecting the ball portion of the mother toe and the ball portion of the small toe.

It is desirable to maintain a lateral arch from the ball of the toe to the ball of the small toe in order to absorb the impact during walking and reduce fatigue. Therefore, the tightening portion 30 of the present embodiment is configured so that the tightening force acts in the direction in which the ball portion of the mother toe and the ball portion of the small toe approach each other. In particular, the tightening portion 30 is configured to tighten the upper 20 in a direction substantially parallel to the straight line connecting the small toe ball portion and the mother toe ball portion.

More specifically, the average of the stretching directions of the inner and outer stretching

portions

32k and 34k extending between the inner stringing portion 28j and the outer stringing portion 28e connected the small toe ball portion and the mother toe ball portion. It is set to be approximately parallel to a straight line. The straight line connecting the ball of the toe and the ball of the small toe is inclined approximately 15 ° with respect to the width direction so that the outer foot side is located behind the inner foot side.

In the first portion 32, the inner / outer extension portion 32k extending from the through portion 28e1 to the central through portion 28j3 is inclined so that the inner foot side is located behind the outer foot side. In the second portion 34, the inner / outer extension portion 34k extending from the through portion 28e3 to the central through portion 28j3 is greatly inclined so that the outer foot side is located behind the inner foot side. On average including these, the average in the stretching direction (= direction of tension) of the inner and outer stretching

portions

32k and 34k is inclined by about 15 ° with respect to the width direction.

Explain the top line of the cuff 20b. As shown in FIG. 1, the top line of the opening 20b may be provided symmetrically on the outer foot side and the inner foot side, but in the present embodiment, the outer foot side and the inner foot side are provided from the viewpoint of making it easier to wear. It is provided asymmetrically with. That is, when putting on shoes, the foot is often inverted and inserted into the opening 20b (with the toe side facing up), and it is easier to put on the shoe when the toe side of the opening 20b is open. Therefore, the top line 20e on the inner foot side (mother toe side) of the cuff 20b of the upper 20 is located in front of the top line 20j on the outer foot side of the cuff 20b. The top line 20j is located in the vicinity of the through portion 28e4 to which the rear end portion 32e of the shoelace 30s is fixed. As shown in FIG. 2, the top line 20j is located above the top line 20e.

The features of the shoe 100 of the present embodiment configured as described above will be described. The shoe 100 has a sole 10, an upper 20 provided above the sole 10 for accommodating the foot, a tightening portion 30 for giving a tightening force to the upper 20, and a tightening force of the tightening portion 30. A force transmission unit 18 for transmitting to the lower portion of the midfoot portion 20 m is provided. According to this configuration, since the tightening portion 30 can be fixed to the lower portion of the midfoot portion 20 m of the upper 20, it is possible to contribute to flattening the distribution of the tightening force in the front-rear direction.

The force transmission unit 18 includes a fastener 36 for detachably fixing the tightening unit 30 to the upper 20. In this case, the tightening force can be transmitted to the upper 20 by a simple structure.

The fastener 36 is fixed near the boundary portion 20h of the upper 20 with the sole 10. In this case, the tightening force can be reliably applied to the foot, which can contribute to flattening the distribution of the tightening force.

The tightening portion 30 includes a first portion 32 and a second portion 34 that are continuous with each other, and a fastener 36 is provided for each of the first portion 32 and the second portion 34. By changing the positional relationship between the boundary 30b of the first portion 32 and the second portion 34 and the fastener 36, the tightening force of one of the first portion 32 and the second portion 34 is strengthened and the tightening force of the other is weakened. Can be done. In this case, the tightening amount can be adjusted between the vicinity of the opening 20b and the toe side.

The tightening portion 30 is a shoelace, and the upper 20 has a lace-up portion 28 through which the first portion 32 or the second portion 34 passes, and the end portion 32e of the first portion 32 and the end portion of the second portion 34. The 34e is fixed to the outer foot side of the upper 20, and the fastener 36 is fixed to the outer foot side. In this case, the shoelace can be easily tightened from the inner foot side to the outer foot side. It can contribute to flattening the distribution of tightening force.

The stringing portion 28 includes an outer stringing portion 28e provided on the outer leg side and an inner stringing portion 28j provided on the inner leg side, and the number of the inner stringing portions 28j is the number of the outer stringing portions 28e. is more than. In this case, the number of inner stringing portions 28j can be dispersed and tightened at multiple points, which can contribute to flattening the distribution of the tightening force.

The lengths of the first portion 32 and the second portion 34 are adjustable in at least one of the fastener 36, the end portion 32e of the first portion 32 and the end portion 34e of the second portion 34. In this case, the length of the shoelace 30s can be adjusted according to the foot size.

The rearmost portion of the first portion 32 constitutes the top line 30h of the tightening portion 30, the front portion of the first portion 32 constitutes the bottom line 30j of the tightening portion 30, and the top line 30h and the bottom line 30j are outside. The foot side is located behind the inner foot side. In this case, the line corresponding to the groin and the MP joint can be properly tightened.

It has a position adjusting mechanism 42 that can move the fixed position of the fastener 36 in the front-rear direction. In this case, the fastener 36 can be fixed at an appropriate position in the front-rear direction.

The top line 20e on the inner foot side of the cuff 20b of the upper 20 is located in front of the top line 20j on the outer foot side of the cuff 20b. In this case, when the shoe 100 is put on, the inner foot side of the shoe opening 20b is opened, which facilitates putting on and taking off.

The tightening portion 30 tightens the upper 20 in a direction substantially parallel to the straight line connecting the small toe ball portion and the mother toe ball portion. In this case, when the foot receives a load, the small toe ball and the ball of the toe expand and the force acts so that the lateral arch collapses, but tighten the foot so that the ball of the small toe and the ball of the toe come close to each other.
