Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to athletics, soccer,
The present invention relates to spike shoes for baseball and golf, and athletic shoes including so-called athletic shoes.

[0002]

2. Description of the Related Art In a general spike shoe, a foot is held by tightening an instep made of fiber or artificial leather. However, in such a structure, the kick force and the rotational force that act on the ground from the legs when landing,
It is inevitable that the laces and eyelets will stretch and the foot will shift laterally and rotate along the back of the foot in the shoe. In particular, most athletes complain of lack of holdability in events such as running 200m in curves and hurdles.

[0003]

Here, as the hold structure of the foot portion, a structure in which a non-stretchable belt is raised from the outer bottom portion of the shoe and tightened instead of tightening the string is conceivable.

However, in such a structure, when the belt is tightened, the force applied to the tarsal portion is concentrated on the belt portion, which causes great pain. Further, when the ankle joint dorsiflexes during running, the tibialis anterior muscle contracts, and the tendon rises. On the other hand, when the phalangeal joint bends back, the extensor pollicis brevis contracts and the tendon rises. The ridges of these tendons change the circumference of the tarsal region, which causes pain due to contact and compression at the belt portion. Further, a linear member such as a belt cannot hold the entire tarsal portion sufficiently.

The present invention has been made in view of the above-mentioned conventional problems, and the purpose thereof is to firmly hold the foot portion so that the kick force can be transmitted to the track or the like without loss and the foot portion is less likely to cause pain. The purpose is to provide shoes for shoes.

[0006]

In order to achieve the above-mentioned object, the first invention of the present application is to provide a shoe in which an instep pad for covering the instep of the foot is formed in a saddle shape with a material having a shape-retaining property. This prevents the tightening force of the tightening material that fits the foot from being applied to a part of the extensor pollicis longus and tibialis anterior muscle of the instep.

According to the present invention, since the instep pad is formed in a saddle shape with a material having a shape-retaining property, the tightening force by the tightening material is applied to the foot via the instep pad, so that the tightening force is dispersed. So, even if you tighten your shoes with a non-stretchable belt,
Less likely to cause pain. In particular, since the tightening force is not applied to the extensor pollicis longus and tibialis anterior muscles of the instep, even if the shoe is tightened with a non-stretchable belt, changes in foot shape due to muscle contraction are allowed. Therefore, pain due to pressure is less likely to occur. Further, since the instep pad is used for holding, the holding property of the tarsal portion is improved.

On the other hand, in the second aspect of the invention, the instep pad covering the instep of the foot is formed in a saddle shape with a material having a shape-retaining property, and the instep pad is provided along the ridge line of the instep pad in the tightened state with the fastening material. It is set so that a space is formed between the instep and the instep.

In the second aspect of the invention, since the space is formed along the ridge of the instep pad, it is possible to prevent the tightening force of the tightening material from being applied to the extensor pollicis longus or the like. The same effect as the invention can be obtained.

This is to prevent the 11B from being deformed to the outside.

As shown in FIGS. 1 and 2, a cutout hole 15 is formed in the rear winding portion 12B of the outer 1. Further, a large number of small holes 16 are formed near the front foot portion and the middle foot portion of the sole portion 10 of the outer 1 in FIG. In addition,
A cover 7 made of a highly elastic mesh-like fiber that covers the front foot is attached to the front foot of the outer 1.

FIG. 8 is a perspective view showing the instep pad 4. The instep pad 4 covers the instep C of the foot as shown in FIG. 9, and is formed in a saddle shape as shown in FIG. 8 with a resin material having shape-retaining property such as 11 nylon. The instep pad 4 forms a space S between the instep C along the ridgeline L and the instep C of the foot, as shown in FIG. 9, while the instep pad 4 is separated from the ridgeline L at the foot part 41 shown in FIG. Touch the left and right parts of instep C as shown in. The upper pad 4 is fastened by the middle belt 3B and the rear belt 3C (FIG. 1), and as shown in FIG. 6, the upper pad 4 and the upper C are arranged along the ridge line L.
Since the space S is set between the belt 3B and a part of the extensor pollicis longus muscle M1 and the tibialis anterior muscle M2 of FIG.
Prevent the application of 3C (Fig. 1) tightening force. It should be noted that the contact portions with the foot parts are hatched, and it is preferable that a cushioning member such as a sponge is attached to the inside of the instep pad 4 at these portions, if necessary.

As shown in FIG. 8, the instep pad 4 has a ridge portion 40.
Is thicker, while the foot portion 41 is thinner than the ridge portion 40. The instep pad 4 is the rear B in FIG.
The front pad 42 in which the ridge line L inclines upward along the foot as it goes to a, and the rear pad 4 in which the ridge line L inclines above the front pad 42 and inclines more than the foot pad
3 and 3 are integrally formed. Between the front pad 42 and the rear pad 43, a cutout portion 44 is formed by cutting out the foot portion 41. Incidentally, the Young's modulus of the instep pad 4 is generally preferable to set to about ^{10kgf / mm 2 ~100kgf / mm 2} .

As shown in FIG. 1, the instep pad 4 is connected to the front winding upper portion 11A to the winding portion 12A of the outer 1 by two connecting plates 5. The connecting plate 5 is composed of a bellows-shaped plate which is separate from the outer 1.

Front belt 3A, middle belt 3B, rear belt 3
C is the upper part 1 of the forefoot, middle foot and heel, respectively.
1A, 11B or winding parts 12A, 12B are tightened. The front belt 3A and the rear belt 3B are fixed to the winding upper portions 11A and 11B or the winding portions 12A and 12B of the front foot and the heel, respectively. On the other hand, as clearly shown in FIG. 9, the middle belt 3B wraps around the back surface 10a of the sole portion 10 of the outer 1 and is fixed to the back surface 10a. In each of the belts 3A to 3C, two belts are connected via a ring 6 (see FIG. 2), and the belt 6 can be folded back and held in a tightened state by a surface fastener portion 3a formed on the surface. It is like this.

The middle belt 3B shown in FIG. 2 is wound along the upper surface of the front pad 42 so that the upper pad 4 fits on the middle foot. The rear belt 3C is wound along the upper surface of the rear pad 43 in a direction in which the heel portion 16 of the outer 1 is attracted. In addition, at the rear end of the ridge portion 40 of the instep pad 4, the engagement protrusion 4 of FIG. 6 for preventing the rear belt 3C from being detached rearward.
5 is preferably provided.

In the above-mentioned structure, the spike shoe has the non-stretchable middle belt 3B and the rear belt 3C shown in FIG.
Is raised from the outer 1 and the foot portion is tightened, so that the belts 3B and 3C are not stretched, so that the holdability of the foot portion is improved. Particularly, in the spike shoe, the outer 1 is fitted to the foot by fixing the three non-stretchable belts 3A to 3C to the outer 1, so that even if the ankle joint or the phalangeal joint is bent or extended, the outer 1 The whole fits your feet well, improving holdability. Regarding the tread portion (foot portion) having different shapes, the middle belt 3B is fixed to the back surface of the sole portion 10 of the outer 1 and the sole portion 10 is treaded by the tightening force of the middle belt 3B. Since it can be closely attached to, the feeling of unity with the foot (fitting property) is improved and the holding property is further improved.

Further, since the instep pad 4 is formed in a saddle shape with a material having a shape-retaining property, the tightening force by the belts 3B and 3C is applied to the foot via the instep pad 4, so that the tightening force is dispersed. Therefore, even if the shoe is tightened with the non-stretchable belts 3B and 3C, pain is unlikely to occur. In particular, since the tightening force is not applied to the extensor pollicis longus muscle M1 and the tibialis anterior muscle M2 in FIG. 5, even when tightened with the non-stretchable belts 3B and 3C, the shape of the foot due to the contraction of the muscles M1 and M2 is reduced. Since changes are allowed, pain due to contact or pressure is unlikely to occur. Furthermore, FIG.
Since the tarsal portion is held by the planar instep pad 4, the holding property is also improved.

Further, the ridge portion 40 of the instep pad 4 is thickened,
On the other hand, since the foot portion 41 is set to be thin, the shape retention of the ridge portion 40 is sufficiently obtained, and the foot portion 41 easily follows the foot, so that the fitting property is enhanced and the pain does not occur.

Further, the rear pad 4 is larger than the front pad 42.
The ridgeline of 3 is inclined upward, and the rear belt 3C is wound along the upper surface of the rear pad 43 of FIG.
Since 6 is attracted, the heel portion 16 of the shoe does not separate from the heel. Therefore, the shoe fits on the foot, which makes it easier to run.

Further, since the notch 42 is formed in the foot portion 41 of FIG. 8, the foot portion 41 of the front pad 42 and the rear pad 43 is formed.
It is easier to fit along the foot, so the fit is further enhanced and there is no pain.

Further, in this spike shoe, front and rear winding portions 12 are further provided on front and rear winding upper portions 11A and 11B in FIG.
Since A and 12B are formed in a row, not only can the forefoot part and the heel part be held from both sides, but also from above, and the tread part can be held by the rear winding upper part 11B. . Therefore, since the holding property is improved, the lateral displacement of the foot in the shoe and the rotation along the back surface of the foot can be prevented, and the kick force can be transmitted to the track without energy loss. Moreover, in addition to the winding portions 11A and 11B, the winding portion 12
Since A and 12B are provided, the contact area between the side surface of the foot and the side surface of the outer 1 becomes large, so that there is no fear of causing pain in the foot.

Further, as shown in FIG. 3, the winding heads 11A, 11
Since the portion of B that rises from the sole portion 10 is set to be thick, the rigidity of the winding heads 11A and 11B is increased, so that the deformation of the winding heads 11A and 11B due to the applied load is suppressed. Therefore, the holding property is further improved.
On the other hand, the winding parts 11A and 11B and the winding part 12
Since A and 12B become thinner toward the upper edge, they easily fit to the foot, so that the fit is enhanced and no pain occurs.

A split portion 13 having a V-shaped cutout is provided between the front winding upper portion 11A and the rear winding upper portion 11B, and the joint plate 14 shown in FIG. The resistance at the time of bending becomes small, while the winding part 11A,
Since the joint plate 14 can suppress the outward deformation of the 11B and the winding portions 12A and 12B, the holding property is improved. Moreover, since the winding parts 11A and 11B are formed over almost the entire circumference of the foot, partial pain due to the concentration of pressure is unlikely to occur.

Further, since the highly elastic cover 7 covering the front foot portion is provided for the foot contact of the front foot portion, the front foot portion can be restrained with a small force from above without obstructing the movement of the finger portion. Further, since the cushioning member 8 is attached to the inner side surfaces of the front and rear winding portions 12A and 12B, the pain caused by the pressure of the hard outer 1 is unlikely to occur.

FIG. 10 shows the intermediate belt 3B and the rear belt 3
Another example of C is shown. As shown in FIGS. 10A and 10C, the middle belt 3B and the rear belt 3C are made of rubber and have a bellows-shaped bellows portion 30, and as shown in FIG. One side surface 31 extends and the other side surface 32 contracts in accordance with the movement. Therefore, both belts 3B and 3C move to a position passing through the shortest distance in response to a change in the shape of the shoe due to flexion or extension of the ankle joint or the like.
A constant tension can be maintained. In addition, the belts 3B and 3C of the present modified example hardly extend even when tension is applied to the belts 3B and 3C, while the belts 3B and 3C are changed as shown in FIG. Although deformed, the lengths of the belts 3B and 3C along the neutral axis N of the belts 3B and 3C hardly change, and thus are included in the scope of the non-stretchable belt of the present invention.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art can easily envision various changes and modifications within the obvious scope by viewing the present specification. Ah For example, the present invention can be applied to spike shoes for soccer, baseball, golf and the like, and athletic shoes that are not provided with spikes, in addition to the spike shoes for track and field of the above embodiment. Further, an inner may be attached to the outer if necessary. Further, the space S in FIG. 9 may be filled with a flexible member such as sponge. Further, instead of thickening the ridge portion 40, a reinforcing rib is provided on the ridge portion 40 to make the ridge portion 40 thin, or a portion of the instep pad 4 that comes into contact with the muscles M1 and M2 is hollowed out. It may be shaped (notched) to prevent the tightening force from being applied to the muscles M1 and M2, and to make the ridge portion 40 more rigid than the foot portion 41. Further, the foot portion 41 may have a bellows structure to reduce the rigidity. Accordingly, such changes and modifications are intended to be within the scope of the invention as defined by the appended claims.

[0032]

As described above, according to the present invention,
Since the instep pad is formed in a saddle shape with a material having shape retention,
Since the tightening force of the tightening material is applied to the foot via the instep pad, the tightening force is dispersed, and therefore even if the shoe is tightened with the non-stretchable belt, the pain is unlikely to occur. In particular, since the tightening force is not applied to the extensor pollicis longus and tibialis anterior muscles of the instep, even if the shoe is tightened with a non-stretchable belt, changes in foot shape due to muscle contraction are allowed. From
Less pain due to pressure. Further, since the instep pad is used for holding, the holding property of the tarsal portion is improved.
In particular, if the shoe is brought into close contact with the foot using a non-stretchable belt, the hold of the foot is significantly improved.

Also, the ridge of the instep pad is made thicker, while
If the foot is thin, the shape of the ridge can be sufficiently retained, and the foot can easily follow the foot, so that the fit is improved, pain is less likely to occur, and the hold is also improved. .

If the ridgeline of the rear pad is tilted upward more than the front pad and the rear belt is wound along the upper surface of the rear pad and the heel of the shoe is pulled, the heel of the shoe is removed from the heel. I won't let go. Therefore, the shoes come into close contact with the feet, which facilitates running.

Further, if the notch is formed in the foot portion, the foot portions of the front pad and the rear pad can easily follow the foot, so that the fitting property is further enhanced.
