Abstract

[PROBLEMS] For footwear or insoles such as high heels and other shoes and sandals, sandals, slippers, various socks, clogs, etc., can effectively reduce the impact and reaction force acting on the toes, and add to the heel when landing Shock can also be buffered.
SOLUTION: In the insole 9 of footwear or shoes, the heel ball part and the buttock abdomen are recessed so that they can be fitted respectively, and other than the deep part of the dent 3 for the heel ball part and the dent 4 for the buttock abdomen. Since there are a plurality of through holes or concave holes h in the region corresponding to at least the index finger, middle finger, ring finger and little finger, the elasticity is softened by the plurality of through holes and concave holes, so that it becomes soft. The cushioning action is improved, and the impact and reaction force on the toes when walking and running are alleviated. The indents in the insole and insole layer of the footwear may be upward or downward.

Description

The present invention relates to footwear such as high heels and other shoes, sandals, sandals, slippers, tabi, clogs, and insoles of shoes, as well as improving the comfort and stability of footwear and correcting obstacles such as posture and O-legs. In addition, it is intended to achieve slimming by tightening the muscles of the legs, and improve the agility of movement and reduce wear of the heel part of the footwear.

As described in Japanese Utility Model Publication No. Hei 5-48976 (Patent Document 1), when playing golf, by putting it in shoes, focus on the base of the big toe and feel the center of gravity of the body. As a result, in order to provide a golf insole for learning how to swing the correct club, it has been proposed to make a circular or oval hole in the base of the thumb of the insole. ing.

Also, as described in Japanese Patent Application Laid-Open No. 2004-275659 (Patent Document 2), a shoe insole that corrects an O-leg in daily life without requiring special equipment or exercise is provided. It has been proposed to reduce the thickness of the area around the baseball of the insole body to loosen the muscles around the hip and knee joints during daily walking and standing, and to increase joint flexibility. Yes.

As described in Patent Document 1, by concentrating the consciousness on the base of the thumb of the toe by opening a hole in the base of the thumb of the insole of the golf shoe in the shape of a circle or ellipse, As a result, you may be able to learn how to swing the club correctly, but you can correct obstacles such as posture and O-legs, tighten the leg muscles to make them slim, and reduce wear on the heel of the footwear It is not possible to obtain effects such as improving the comfort and stability of footwear. Moreover, it is impossible to move quickly and easily.

On the other hand, as in Patent Document 2, the muscles around the hip joint and knee joint are loosened during daily walking or standing by reducing the thickness of the insole body periphery of the shoe insole body. It can increase the flexibility of the joint, and can correct the O-leg in daily life without the need for special equipment or exercise.

However, in the case of the present invention, it can be applied only to insoles of shoes, the scope of application is limited, and it cannot be applied to footwear in general. Further, even in the case of the insole, it is not possible to achieve a sufficient correction effect such as posture and O-leg only by reducing the thickness of the insole main body periphery. In addition, it is not possible to obtain effects such as tightening and slimming the muscles on the inside of the foot, reducing wear on the heel of the footwear, improving agility of movement, and improving the comfort and stability of the footwear.

The inventor of the present invention pays attention to such problems, and can improve not only the insole of the shoe insole or the sole of the footwear itself, but also correct the obstacles such as posture and O-leg, as well as the inside of the foot Tighten the muscles of the foot to make the entire foot slim, reduce wear on the heel of the footwear, improve the comfort and stability of the footwear, and provide a sense of unity with the foot. Japanese Patent Application No. 2005-371209 (Patent Document 3) has been proposed in order to realize a structure that is effective and suitable for agile movements and can be exercised easily.

Next, an insole of footwear or shoes described in Patent Document 3 will be described in detail with reference to FIGS. FIG. 1 is a horizontal cross-sectional view showing a flat state of a shoe sole portion on the right foot side, which is an embodiment implemented on a shoe. Reference numeral 1 denotes an inner surface (upper surface) of a shoe bottom portion, and a side wall portion 2 of the shoe rises from an outer peripheral portion thereof. When this shoe is worn, the depression 3 is formed in the area where the main ball part that wraps the joint of the base of the main rod contacts, and the depression 4 is formed in the area where the belly of the main ring contacts. And the shallow hollow 5 is made to continue between the said hollow 3 in which the above-mentioned main ball part enters, and the hollow 4 in which the mother's stomach part enters.

When this shoe is worn, since the area where the main ball part abuts is the largest, the depression 3 into which the main ball part enters is the largest, and the area where the abdomen abdomen comes into contact next is large. The recess 4 is next larger. And the hollow 5 which continues between the hollow 3 in which a main ball part enters, and the hollow 4 in which a mother calf part enters is formed somewhat shallowly and narrowly. As a result, the overall shape is almost bowl-shaped. However, it is not symmetrical with respect to the center line (A-A line), and only the depression 3 for the main ball part is inflated to the outside like the part f so as to match the main ball part.

FIG. 2 is a longitudinal sectional view showing the shape of each of the depressions 3, 4, and 5 in the depth direction, (1) is a sectional shape at the position AA in FIG. 1, and a chain line S is a shoe upper, The concavo-convex surface E is a shoe outer bottom surface in contact with the ground. Therefore, T is the total thickness of the shoe sole, and its dimensions are arbitrary. As is clear from this cross-sectional view, the dent 3 into which the main ball part enters is deepest, and then the dent 4 into which the main part abdomen enters. And the hollow 5 which continues between the hollows 3 and 4 is the shallowest, and has become a shallow groove shape.

(2) to (4) in FIG. 2 are a position B-B of the depression 4 for the mother calf region shown in FIG. 1 and FIG. 2 (1), a position C-C of the shallow depression 5 for continuous use, It is a longitudinal cross-sectional view which shows the cross-sectional shape of the shoe width direction in position DD of the hollow 3 in which a Ryukyu part enters. As is clear from these cross-sectional views, the depression 3 into which the main ball part enters is the widest in the shoe width direction, and the next depression 4 into which the mother's abdominal part enters. And the shallow hollow 5 which continues between the hollows 3 and 4 is the narrowest, and has become a narrow groove shape.

Further, as is apparent from FIGS. 2 (1) to (4), the recesses 3, 4, and 5 are inclined so as to gradually become deeper from the outer peripheral side toward the central portion. . And the central part is deepest.

Since the dent 3 for the main ball part, the dent 4 for the mother's abdomen and the dent 5 for continuation are formed on the bottom surface (the inner surface of the sole) of the shoe, the shoe was worn. In this case, as shown in FIG. 3, the main ball 6 projecting downward from the foot F is fitted into the depression 3 for the main ball, and the lower belly 7 projecting downward is the depression for the mother belly. 4 is inserted. Then, the valley-shaped portion 8 retracted to the upper side between the lower rib portion 7 and the lower ball portion 6 that protrudes downwardly fits into the continuous shallow recess 5. In this way, when the shoe is worn, the main ball 6, the mother belly 7, and the valley 8 are inserted into the corresponding recesses 3, 4, 5. The calf portion 7 and the valley-like portion 8 and the shoe bottom portion are completely fitted and become more integrated.

As a result, when walking or running while wearing these shoes, horizontal slip is unlikely to occur between the base ball part 6, the base part 7 and the valley part 8 and the shoe bottom part, and the comfort is stable. To do. Therefore, there is less risk of slipping or falling when walking or running, and stable walking and running are possible. Also, when sports or manual labor, it is easy to put the force on the mother's heel by pinching the shallow dent 5 between the mother's ball 6 and the mother's abdomen 7, so that the tension is effective. It is also suitable for manual labor. Even when standing, the muscles inside both legs are stretched, so both legs are slimmed down as a whole, and at the same time, bad posture and O-legs are corrected naturally. In addition, the heel portion of the shoe becomes difficult to wear.

In conventional sports shoes, etc., we try to put effort into the mother's mother forcibly, so there is also a problem that it will gradually cause hallux valgus and hinder the improvement of the record, but it has been illustrated from the early stage of elementary and junior high school students If you put on your shoes, you will not be able to cause hallux valgus because you will not be forced to apply unnatural force, but will be caught in the shallow dent 5 and naturally kick the ground. Therefore, it has an advantageous effect on the improvement of recording.

FIGS. 1 to 3 show an embodiment implemented on the bottom of high heels or other shoes. In the case of footwear other than shoes, that is, sandals, sandals, socks, slippers, clogs, etc. By forming the dent 3 for the ball, the dent 4 for the mother's abdomen, and the shallow dent 5 for the valley portion between them, the same effect as in the case of the shoe sole is produced. Moreover, when a hollow cannot be formed in the bottom part of shoes, or when wearing the conventional shoes, it is also possible to implement on the insole of shoes.

FIG. 4 is a longitudinal sectional view implemented on the insole of the shoe, and has the same configuration as the upper side from the chain line LL in FIG. The planar shape is the same as in FIG. In the case of the insole 9, the thickness is limited, and it is difficult to form the deep recesses 3, 4, so it is conceivable to substitute the through holes 3 h, 4 h. In this case, since the valley-like depression 5 is shallow, it can be left as a shallow groove-like depression 5, but it may be left as a through hole. However, if the through-hole is formed without leaving the shallow depression 5, it becomes a bowl-shaped slit as shown in FIG. 1, and the strength decreases and at the same time, the catch of the valley-shaped portion 8 becomes worse. On the other hand, when the both sides are connected with the remaining shallow depression 5, the strength is prevented from being lowered, the service life is prolonged, and the catch of the valley portion 8 is improved.

The cross-sectional shape in the shoe width direction has the same configuration as the upper side from the chain line LL in FIGS. The point which inclines so that it may become deep gradually toward the center part from the outer peripheral side of the holes 3h and 4h and the hollow 5 is exactly the same as FIG. Therefore, when this insole is laid, as in the case where the depressions 3, 4 and 5 are formed in the bottom of the shoe itself as shown in FIGS. It is possible to suppress horizontal slippage between the portion 8 and the shoe sole. As a result, it is easy to wear, stability when standing or walking is improved, and agility of movement is also improved. Therefore, when the illustrated footwear or insole of the shoe is used, there is an effect that the risk of slipping or falling is avoided even in the case of an elderly person or a disabled person.

Since the holes 3h, 4h and the recess 5 are inclined so as to gradually deepen from the outer peripheral side toward the center, there is no angular part, and there is a risk of giving strong stimulation to the soles or feeling pain However, after testing with a prototype, a new problem was found that when the insole moves, there is a risk of shoe rubbing and blistering. Since the foot hits the bottom of the shoe itself and the insole, movement of the insole will occur due to fluctuations in the state of the force acting on both.

Therefore, as shown in FIG. 6, it is desirable to provide recesses 3 and 4 instead of the holes 3h and 4h. If it is absolutely necessary to make the through holes 3h and 4h, it is conceivable that a thin sheet is stuck on the lower surface to close the through holes 3h and 4h. In the case of FIG. 6, the deep recesses 3 and 4 and the shallow recess 5 are provided within the range of the thickness t of the insole. Therefore, when the thickness t is sufficiently thick, the deep depressions 3 and 4 and the shallow depression 5 can be formed as in the case of FIGS. 2 and 3, but when the thickness t is thin, the depressions 3 and 4 are shallow. Since the thin insole 9 has the depressions 3 and 4 even if it is shallow, the sense of unity between the foot and the shoe increases, the foot struts work, and the foot does not hit the shoe itself. There is no risk of skidding, and it is difficult for shoes to rub.

When I happened to wear normal shoes and went to the foot oil massage, when I went home without wiping the oil, my feet slipped in the shoes, and I needed to be careful even during normal walking. I walked with the insole shown. As a result, slipping was clearly reduced even without wiping the oil, and the effect of the insole shown in the figure could be demonstrated without particularly feeling the need to walk carefully.

FIG. 5 is an embodiment in which the cloth-like sheet 10 is pasted on the upper side surface 1 where the depressions 3 to 5 are formed as described above, (1) is a state where the sheet is pasted, and (2) is a state where the seat is worn. is there. The sheet 10 is preferably a cloth-like body having good air permeability and good hygroscopicity so that the feet do not get stuffy. Nonwoven fabric may be used. When this sheet 10 is adhered and adhered to the upper surface 1 of the shoe sole (the surface on the side where the main ball ball portion or the mother calf belly portion is in contact) 1 with an adhesive, the state shown in FIG. The sheet 10 may be applied only to the area around the recesses 3 to 5, but it is better to apply the sheet 10 on the entire surface. When the sheet 10 is pasted in this way, the recesses 3 to 5 are hidden under the sheet 10 and cannot be seen as shown in FIG.

FIG. 5 (2) shows a state in which the shoe with the seat 10 is worn, and the lower part of the main ball part 6 that protrudes downward from the foot F and the lower part 3 of the main part of the main ball part corresponding to the lower part of the foot part 7 When entering into the depression 4 for the mother stomach, the sheet 10 is also pushed in, resulting in an uneven state as shown in FIG. That is, since the seat 10 extends and is pushed into the recesses 3 and 4, the effect of improving the comfort by the recesses 3 and 4 is not reduced. As described above, when a cloth-like body is used as the sheet 10, a rough texture is generated, and thus an advantage that the foot is more difficult to slip is also generated.

When the sheet 10 is affixed to the upper surface of the insole 9 of FIG. 4, only the cross-sectional shape above the chain line LL in FIG. 5 (1) is obtained, and the through holes 3h and 4h in FIG. Since it is hidden under the sheet 10, the appearance does not deteriorate even in the case of an insole.

If each insole in the above embodiment is for the right foot as shown in FIG. 1, it can also be used for the left foot if the front and back are reversed. This is because the depressions 3, 4, and 5 are formed on the upper side by gradually sinking during use. Therefore, it is not necessary to manufacture two types of right foot and left foot, and if only one type is manufactured, it can be used for both the left and right feet, so that the manufacturing cost can be reduced.

When the insole 9 having the upward depressions 3 and 4 in FIG. 6 is inverted, it becomes as shown in FIG. The insole is not manufactured with a strong rigid body, but is manufactured with relatively soft synthetic resin or felt, so if it is inclined so that it gradually becomes deeper from the outer peripheral side toward the center of the recess, it will be turned over. Even if it is used, it will be stepped on and deformed while being used, and soon, the flat upper side surface of FIG. Therefore, even if it is turned over from the beginning, there is no particular problem. Of course, you may form the hollow and inclination in the back surface from the beginning. Moreover, the structure which inclined both front and back is also possible, and in this case, it becomes an insole which does not distinguish left and right from the beginning. In the case of the insole 9 in FIG. 4, if the sheets 10 are pasted on both the upper and lower surfaces, there is no distinction between the front and the back.

The above insole can be cut at an intermediate position between the front and the back, and only the first half portion having the depressions 3 and 4 can be used. Therefore, the insole of only the first half portion having the depressions 3 and 4 is sufficient, and particularly effective in the case of high heels, and also has an effect of being easy to wear. In other words, if it is a long insole that extends to the heel part, the upper part of the heel slips down while it is worn and wrinkles. However, if the shape does not have the latter part, such a problem does not occur. In the case of sandals and slippers, the shape of only the first half with the second half cut off is also possible.

FIG. 7 shows that in the insole 9a of the shoe, recesses 3 and 4 are provided on the shoe sole side (lower side) surface in the region corresponding to the baseball ball portion and the region corresponding to the belly portion of the baseball, A shallow depression 5 is provided. In this way, the lower surface of the insole is provided with the dent 3 corresponding to the main ball part and the dent 4 corresponding to the abdomen of the main part, and the shallow dent 5 is provided between them, The first flat upper side surface is depressed as a result of being pushed by the main ball and the abdomen, resulting in contact with the upper sole of the insole as shown in FIGS. Then, the depressions 3 and 4 and the shallow depressions 5 into which the main ball part and the mother's abdominal part can enter are formed. Thus, when forming a dent only in a lower side from the beginning, it cannot be overemphasized that an insole for exclusive use of right and left is needed.

FIG. 8 shows a configuration in which the insole of FIG. 7 is integrated with the inner bottom portion of the shoe from the beginning by bonding or other methods. That is, the insole layer 91 is integrated with the inner bottom surface of the shoe. The insole layer 91 is provided with a dent 3 corresponding to the heel ball part, a dent 4 corresponding to the abdomen of the heel and a shallow groove-like dent 5 on the surface of the sole body B side. As a result, the first flat upper surface 91s is gradually depressed by being pushed by the main ball and the abdomen of the main ball while in use, and as a result, the upper sole of the insole layer 91 is depressed. It will be in the state where the depressions 3, 4, and 5 into which the main ball part, the main belly part, and the valley part could just be inserted were formed on the contact surface.

As shown in FIGS. 1 to 6, when a depression is provided on the back side, that is, the lower side of the surface in contact with the heel ball part or the heel abdomen part, such as the insole 9a of FIG. 7 or the insole layer 91 of the shoe of FIG. It is desirable to form it larger than the size of the dent provided on the upper side where the main ball ball part and the mother calf belly part contact. If it is formed in a large size in advance, when it is used repeatedly and the upper surface gradually sinks, it becomes a perfect dent size that is just suitable for the insertion of the baseball ball part and the base part of the belly. 7 and FIG. 8, if the same size as that formed on the upper side is also formed on the upper side as indicated by solid lines 3 and 4, in the depressed state after repeated use, the user's main ball and ball It becomes a depressed depression that is smaller than the size of the abdomen, and is smaller than the optimum size.

That is, when the dent is on the lower side, the thickness of the insole 9a and the insole layer 91 is previously taken into consideration, and as shown by the chain line, it is previously formed larger. Therefore, it is necessary to determine a larger degree in consideration of the material of the insole and the insole layer, that is, hardness and flexibility. For example, in the case of a highly flexible material, it is sufficient to make it slightly larger, but in the case of a harder material, it is necessary to form it larger.

As described above, the footwear or the insoles of Patent Document 3 are inserted into the corresponding depressions 3, 4, and 5, respectively, by the main ball portion 6, the lower belly portion 7, and the valley portion 8. When the shoe is worn, the base ball part 6, the base part 7 and the valley-like part 8, and the shoe sole part and the insole are completely fitted to be integrated with the foot. As a result, when walking or running with this footwear, horizontal slip is unlikely to occur between the baseball 6, the base 7 and the valley 8 and the bottom of the footwear, and the comfort is stable. The risk of slipping or falling when walking is reduced, and stable walking and running are possible.

In addition, it is easy to get tired even if you wear it for a long time. Therefore, it seems that you are walking or running on the ground with bare feet, and it is effective even when you play sports, and you can move quickly and accurately and quickly and quickly, and even in the case of a marathon, you lose your movement. Less is. The muscles inside both legs are stretched to make both legs slim, and at the same time, the O-leg is naturally corrected, and the shoe's heel part is less likely to be worn away.

  However, while using the footwear or insoles described in Patent Document 3, it has been found that there is still room for improvement. That is, since the footwear or insole of Patent Document 3 is made of the same material as a whole, there is a problem that the elasticity applied to the toe portion is too hard and the impact and reaction force on the foot are too strong. It was. Therefore, the technical problem of the present invention is to pay attention to such a problem and to effectively relieve the impact and reaction force acting on the toes, and to make it possible to buffer the impact applied to the heel when landing.

The technical problem of the present invention is solved by the following means. Claim 1 is that in the insole of footwear or shoes, the area corresponding to the baseball ball part and the area corresponding to the belly part of the baseball are recessed so that the baseball ball part and the baseband abdomen can be fitted respectively. As shown in FIG. 9, a plurality of regions other than the deep portions 3d and 4d of the depressions for the main bulb and the abdomen are used in at least the regions corresponding to the index finger (second toe), the middle finger, the ring finger, and the little finger. An insole for footwear or shoes having a through hole or a concave hole.

In this way, in the insole of footwear or shoes, the area corresponding to the baseball part and the area corresponding to the abdomen of the baseball are recessed so that the baseball part and the base part of the base can be respectively inserted. Moreover, since there are a plurality of through-holes or concave holes at least in the areas corresponding to the index finger, middle finger, ring finger and little finger in the area other than the depression for the main ball and the abdomen, the footwear or the shoes The elasticity of the area corresponding to the index finger, middle finger, ring finger, and little finger on the floor is softened by softening through multiple through holes and concave holes, so the cushioning action is improved and the impact on the toes when walking or running And reaction force is eased. The concave holes in the insole and the insole layer of the footwear may be upward or downward.

A second aspect of the present invention is the insole of footwear or shoes according to the first aspect, wherein the plurality of through holes or concave holes are arranged in the directions of the index finger, the middle finger, the ring finger, and the little finger, respectively. As described above, since the plurality of through holes or concave holes are arranged in the respective directions of the index finger, the middle finger, the ring finger, and the little finger, the elasticity of each toe can be effectively softened. When a person is walking, the last force from the ground is applied to the toes, and the reverse force is applied to the joints, so the elasticity acting on the toes is weaker and softer. Desirably, it is also important in reducing toe fatigue.

According to a third aspect of the present invention, the through hole or the concave hole in the region corresponding to the ridge is arranged from the rear outer side toward the inner crotch on the arch side as shown in FIGS. The insole of footwear or shoes according to claim 1 or claim 2. In this way, the through holes or concave holes in the area corresponding to the heel are not dispersed throughout the heel side, but rather from the rear outside along the direction of movement of the point of action of body gravity in the heel area when landing. Since it is arranged toward the inner crotch, it is possible to effectively buffer the impact received from the ground against the heel.

According to a fourth aspect of the present invention, the depression for the main ball and the depression for the lower abdomen and / or the depression on the heel side of the insole or insole layer is provided downward. An insole for footwear or shoes according to Item 2 or Claim 3. By inverting the insole or insole layer in which the depression for the main ball ball part, the depression for the mother abdomen part and the concave hole on the heel side are formed upward, it can be easily turned downward. As described above, when the depression for the main ball part and the depression for the mother abdomen are provided downward, as shown in FIGS. 7 and 8, the flat upper surface is depressed while wearing, and the upward It transforms into a depression for the main ball part and a hollow for the mother's abdomen. Moreover, since the concave hole on the heel side of the insole or the insole layer is provided downward, the hole or the concave hole is not visible from the upper side during use and is not conspicuous. Therefore, when the insole of the footwear itself such as shoes is an insole layer 91 integral with the shoe body B as shown in FIG. 8, a concave hole is made from the lower surface side of the integral insole layer 91. In this case, a separate insole is not always necessary.

According to a fifth aspect of the present invention, the region corresponding to the above-described limb portion and the region corresponding to the heel portion of the limb are continuously connected by a dent for the basal limbs or a dent for the heel portion of the limb, which is shallow. The insole according to any one of claims 1 to 4, wherein a plurality of through holes or concave holes are provided in the recess. In this way, the region corresponding to the above-described limb portion and the region corresponding to the heel portion of the heel are continuously connected by a dent for the heel ball or a dent for the heel portion of the heel, and this shallow dent. In addition, since there are multiple through holes or concave holes, the elasticity to the soft area of the skin between the ball and ball parts of the sole is softened, and air is passed through the through holes and the concave holes. By going in and out, it is possible to suppress the stuffiness of the skin.

According to a sixth aspect of the present invention, the recess is inclined so as to gradually become deeper from the outer peripheral side toward the central portion, and a through hole or a concave hole is provided on the entire circumference or a half circumference or more along the upper end of the inclination. The footwear or the insole of the footwear according to any one of claims 1 to 5, wherein the footwear or the shoe insole is provided. As described above, the recess is inclined so as to gradually become deeper from the outer peripheral side toward the central portion, and a through hole or a recessed hole is provided over the entire circumference or a half circumference along the upper end of the inclination. For this reason, when air enters and exits the through hole and the recessed hole, it is possible to suppress the stuffiness of the skin around the mother ball part and the mother belly part.

According to a seventh aspect of the present invention, at least the side of the insole or footwear that contacts the sole of the foot is made of an elastic synthetic resin plate or foamed resin plate, and each of the concave holes is formed by pressure compression. An insole for footwear or shoes according to any one of claims 1 to 6. As described above, since the concave hole is formed by pressure compression, it is easy to manufacture, and at least the side in contact with the sole of the foot such as the insole or insole layer of the shoe is elastic. Since it is composed of a synthetic resin plate or a foamed resin plate, coupled with the softening of elasticity by the through holes and concave holes, the impact and reaction force on the toes are more effectively mitigated, and foot fatigue is less likely to occur.

8. An insole for footwear or shoes according to any one of claims 1 to 7, wherein a non-slip cloth is bonded to the surface in contact with the sole. It is. As described above, since the anti-slip cloth is bonded to the surface in contact with the sole, the anti-slip effect can be obtained and sweat can be absorbed by the cloth. Moreover, if this cloth is affixed on the through hole on the heel side, this cloth also serves as the bottom of the concave hole, so that the concave hole can be formed by the through hole.

As in claim 1, in the insole or insole layer of footwear or shoes, the region corresponding to the baseball and the region corresponding to the abdomen of the base can be respectively inserted into the base and base. In addition, a plurality of through holes or concave holes are provided in regions corresponding to at least the index finger, middle finger, ring finger and little finger, so that the index finger, middle finger in the insole or insole layer of footwear or shoes, Since the elasticity of the area corresponding to the ring finger and little finger is softened by multiple through holes and concave holes, the cushioning action is enhanced, and the impact and reaction force on the toes when walking or running is mitigated .

Since the plurality of through holes or concave holes are arranged in the directions of the index finger, the middle finger, the ring finger, and the little finger, respectively, the elasticity with respect to each toe can be effectively softened. When a person is walking, the last force from the ground is applied to the toes, and the reverse force is applied to the joints, so the elasticity acting on the toes is weaker and softer. Desirably, it is also important in reducing toe fatigue.

As in claim 3, the through holes or the concave holes in the region corresponding to the heel are not dispersed throughout the heel side, but from the rear outer side along the moving direction of the action point of body gravity in the heel portion at the time of landing. Since it is arranged toward the inner crotch side of the arch side, it is possible to effectively buffer the impact received from the ground against the heel.

As described in claim 4, when the depression for the main ball part and the depression for the mother's abdomen are provided downward, the flat upper surface is depressed while wearing, and the depression for the upper part of the main ball part. And deformed into a depression for the mother's abdomen. Moreover, since the concave hole of the area | region corresponding to the insole or the insole layer's ridge is provided downward, a hole and a concave hole are not visible from the upper side at the time of use, and are not conspicuous.

As in claim 5, between the region corresponding to the above-mentioned limb part and the region corresponding to the antrum region is continued with a dent for the basal bulb and a dent for the ankle region, Since this shallow depression is also provided with a plurality of through holes or concave holes, the elasticity to the soft area of the skin between the heel ball part of the sole and the thigh abdomen is softened. When the air enters and leaves the skin, it is possible to suppress the stuffiness of the skin.

According to a sixth aspect of the present invention, the recess is inclined so as to gradually become deeper from the outer peripheral side toward the central portion, and through holes or concave holes are formed on the entire circumference or a half circumference or more along the upper end of the inclination. Since it is provided, it is possible to suppress the stuffiness of the skin around the mother ball part and the mother's abdomen by allowing air to enter and exit the through hole and the concave hole.

As described in claim 7, since the concave hole is formed by pressure compression, it is easy to manufacture, and the side in contact with the sole, such as a shoe insole or insole layer, is elastic. Since it is composed of a synthetic resin plate or a foamed resin plate, coupled with the softening of elasticity by the through holes and concave holes, the impact and reaction force on the toes are more effectively mitigated, and foot fatigue is less likely to occur.

As described in claim 8, since the anti-slip cloth is bonded to the surface in contact with the sole, the anti-slip effect can be obtained and sweat can be absorbed by the cloth. Moreover, if this cloth is affixed on the through hole on the heel side, a concave hole can be formed by the through hole.

Next, an embodiment of how the footwear or insole with a through hole or a recessed hole according to the present invention is practically described will be described. FIG. 9 is a plan view of an insole or shoe insole with through holes or concave holes according to the present invention, F1 is a thumb, F2 is an index finger (second toe), F3 is a middle finger, F4 is a ring finger, and F5 is a little finger. is there. In the shoe sole 1 or insole 9 made of a synthetic resin plate or a foamed resin plate, the depression 3 is formed in the area where the main ball part abuts, and the depression 4 is formed in the area where the abdomen of the main figure contacts. is there. And the shallow hollow 5 is made to continue between the said hollow 3 in which the above-mentioned main ball part enters, and the hollow 4 in which the mother's stomach part enters.

A number of holes (through holes or concave holes) h... Are formed in areas other than the thumb F1, that is, the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5. The holes h may be randomly distributed, but may be regularly arranged in a grid pattern, a zigzag pattern, a staggered pattern, or the like, and is not particularly limited. As described above, when a large number of holes h are formed in the regions of the fingers F2 to F5 other than the thumb F1, the holes h are easily deformed in the closing direction when receiving weight from the foot side. By h ..., the elasticity in the vicinity becomes weak and soft, and the cushioning property is enhanced.

As a result, even if it receives an impact or reaction force from the ground when walking or running, the impact and reaction force received by each finger is alleviated and acts as a cushion to protect the toes. It ’s hard to get tired. In addition, the flow of air occurs in the vicinity due to the movement of the toes when running or walking, or the holes h are partially formed by the movements of the toes or by the movements in the opening and closing directions of the holes h as described above. It is closed or opened repeatedly repeatedly or entirely. That is, when the body weight is received, the hole h is deformed in the closing direction, and when the foot is lifted from the ground, the body weight is not received, so the hole h is restored to the original. By repeating such an operation, air in a large number of holes h... Enters and exits, so that the toes are prevented from getting steamed and refreshed. Note that the deep portions 3d and 4d of the depression 3 for the main ball portion and the hollow portion 4 for the main rib portion are fitted with the main ball portion and the lower belly portion, so that a through hole or a recess is formed in a region other than the deep portions 3d and 4d. There is a hole h ... Even in the interior of the depression 3 for the main ball part and the depression 4 for the mother's abdomen, it is preferable to open it closer to the outer periphery.

10 is arranged in the longitudinal direction of the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5 as holes h1,. Thus, by arranging the holes h1,..., H2... In the longitudinal direction of the index finger F2, middle finger F3, ring finger F4, little finger F5, the elasticity acting on each finger F2, F3, F4, F5 is effectively softened. It is effective in reducing toe fatigue.

If only the purpose of softening the elasticity is to provide, it is effective to arrange the holes h1... Just below the fingers F2 to F5. FIG. 11 is a cross-sectional view taken along the line E-E in FIG. 10, and when the body weight is not applied, (1) Although the openings of the holes h1... Just below the fingers F2 to F5 are open as shown in FIG. On the other hand, when the body weight is applied, as shown in (2), the openings of the holes h1... Just below the fingers F2 to F5 are deformed in the closing direction according to the body weight, and the toes themselves close the holes h1. Acts as

However, in order to improve the air permeability by the holes, it is effective to arrange the toes at positions adjacent to each other like the holes h2..., Not directly below the fingers F2 to F5. This is because each toe itself becomes a lid of the hole h2 to open and close the hole h2, and the inside of the hole h2 is ventilated by the movement of air generated by the movement of the toe as described above.

As shown in FIG. 2 and FIG. 3, the above-described depression 3 for the main ball part and the depression 4 for the mother's abdomen are inclined so as to gradually become deeper from the outer peripheral side toward the central part. Are provided with holes (through holes or recessed holes) hc... As a result, the elasticity in the vicinity of the holes hc... Is softened, and the ventilation around the holes hc. However, only the region 11 on the arch side is not provided with the holes hc. This is because the arch side does not sweat much, and the arch part is retracted to create a space, which makes it difficult to stuffy. Therefore, it is not necessary to provide the holes hc... At the upper end of the inclination on the entire circumference of the upper end of the inclination, and it is sufficient if they are provided on a half or more circumference as shown.

As shown in FIG. 2 and FIG. 3, a dent shallower than the dent 3 for the main limb and the dent 4 for the pelvic abdomen is formed between the region 3 corresponding to the above-mentioned main limb part and the region 4 corresponding to the heel part. 5, a plurality of holes (through holes or concave holes) h... Are also provided in the shallow recess 5. As a result, the cushioning action is enhanced by the softening of the elasticity by the holes h... And the impact and reaction force received by the valley portion 8 of the sole are alleviated, and the steaming is suppressed by the ventilation action by the opening and closing operations of the holes h. The In addition, when the holes h, h1, h2, and hc are concave holes, the upward concave holes are used. By inverting the insole and insole layer formed with the depression 3 for the main ball and the hollow 4 for the mother's abdomen, the depression 3 for the main ball and the depression 4 for the mother's abdomen as shown in FIGS. If it is faced down, the flat top surface will sag and deform into an upward recess during use.

As shown in FIG. 9 and FIG. 10, the region 12 corresponding to the ridge is also provided with a large number of holes h... Or a recessed hole hu. It is preferable to arrange them along the direction of movement of the body weight by the foot, instead of distributing the concave holes hu. As a result, the numerous holes h... Or the recessed holes hu in the heel side region 12 are arranged from the rear outer side of the footwear or shoes toward the inner crotch on the arch side. Moreover, it is slightly curved so that the outer side is convex and the inner crotch side is concave. Thus, since it has arranged along the moving direction of the load by weight, the shock received from the ground with respect to a bag can be buffered effectively.

In the case of FIG. 9, the heel side is also a through hole h. However, in order to improve the appearance, as shown in FIG. 10, a concave hole hu is provided from the lower surface side so that it cannot be seen from the upper side. It is good. And formation of each concave hole hu ... is preferably processed by pressure compression. That is, as shown in FIG. 12 (3), by pressing from one side to the middle with the punch P, a concave depression hu is formed. The inner diameter of the concave holes hu may be constant as shown in FIG. 12 (1), but may be trapezoidal with different inner diameters in the depth direction as shown in FIG. 12 (2).

By attaching a non-slip cloth to the side of the insole or insole layer that contacts the sole, it acts as an anti-slip between the insole or insole layer and the sole, and can absorb the sweat of the sole . Further, when the non-slip cloth is stuck on the through-holes h on the heel side of FIG. 9 as well, a downward concave hole is formed, and the through-holes h are hidden from the upper side and become invisible. In the manufacturing method, after opening the through holes h on the heel side, a non-slip cloth is bonded to the entire surface, and then the through holes h, h1, h2, and hc on the toes are opened. In addition, the size (diameter) of the through holes h, h1, h2, hc, and the concave holes hu is 1 to 4 mm, particularly 2 to 3 mm. About 5-15 mm is suitable for the pitch (space | interval between centers) of each through-hole h, h1, h2, hc, and the concave hole hu, and about 7-13 mm is especially suitable.

The through hole or the concave hole h... Hole hc... Has a perfect circular shape, but a more complicated shape other than the perfect circle is suitable for softening the elasticity. For example, as shown in FIG. 13, an elliptical shape, an elliptical cross shape, a triangle shape such as a triangle shape, a quadrilateral shape, a pentagonal shape, a star shape, and the like have an opening as shown in FIG. Easy to deform in the closing direction. On the other hand, the perfect circular shape is easy to process, but is not easy to deform in the opening closing direction.

It is effective that the insole 9 of the shoe or at least the side 1 in contact with the sole of the footwear is made of an elastic synthetic resin plate or a foamed resin plate. Thus, when the insole 9 of the shoe or the bottom side 1 of the footwear itself is an elastic synthetic resin plate or foamed resin plate, the fatigue of the foot is also reduced by the elasticity of the insole 9 or the footwear bottom side 1 itself. This is because an effect can be expected. In addition, a synthetic resin plate or a foamed resin plate is suitable for processing and forming through holes and concave holes and reducing material costs. It is also possible to use felt or rubber.

As described above, according to the present invention, in the insole or shoe insole having the depression 3 for the baseball ball and the depression 4 for the mother abdomen, at least in the region corresponding to the index finger, middle finger, ring finger, and little finger, Since there are a plurality of through holes or concave holes, the cushioning property by the opening of the through holes or concave holes is improved compared to the areas other than the index finger, middle finger, ring finger, and little finger, so that the toes can be used when walking or running It effectively absorbs and relieves shocks and reaction forces received from the ground side, which is effective in reducing fatigue and protecting toes.
