Description

  The present invention relates to a shoe sole used in a shoe with a heel such as a high heel or a pump, and a technique related to a shoe having the shoe sole.

Conventionally, shoe soles used for shoes with heels such as pumps are, for example, those in which the shoe sole and the heel are integrally formed (for example, see Patent Document 1), or the heel is provided separately from the shoe sole. The heel is fixed to the shoe sole by a screw nail, a peg or the like (see, for example, Patent Document 2).
JP 2002-85110 A (3rd page, FIG. 1) Japanese Utility Model Laid-Open No. 5-2704 (pages 5 and 6; FIGS. 1 and 3)

However, the above conventional shoe sole has the following disadvantages.
1) A shoe sole formed integrally with a heel cannot be used for shoes of models having different heel heights.
2) The shoe sole provided separately from the heel is generally called a light sole and is hard and formed of synthetic leather or the like, so it has poor flexibility, and the shoe has this sole. If you wear it, it may be difficult to walk. Moreover, since it lacks cushioning properties, it cannot be said that it is comfortable to wear.

  Accordingly, the present invention provides a shoe sole that can be used in common for shoes of models with different heel heights, and that is easy to walk and comfortable to wear, and a shoe equipped with the shoe sole. It is an issue.

  The shoe sole according to claim 1 is a shoe sole of a heeled shoe comprising a toe portion, a stepping portion, an arch portion, and a heel portion, and a separate heel attached to the same heel portion, and the entire shoe sole is made of a rubber material. And forming a recess that constitutes a closed space when the upper part is covered by the insole, from the toe part to the stepping part. Provided with a plurality of buffer plates that divide the inside in the shoe length direction, each buffer plate is provided with a ventilation portion that allows air to flow in the shoe length direction, one end communicating with the recess and the other end of the arch portion The air flow path opened in the back surface of this is provided.

  According to the shoe sole of claim 1, since the whole is integrally formed into a plate shape with a rubber material, it is excellent in flexibility. Therefore, it can be used by freely bending, and can also be used in common for models of shoes having different sole shapes due to the difference in heel height.

  Furthermore, because it has good flexibility, it is easy to fit the movement of the foot during walking, and the elasticity of rubber and the cushioning property due to the bending of the buffer plate in the recess can improve the feel of the sole of the foot and Can absorb the impact of time.

  Moreover, the air in the shoe can be circulated by the concave portion constituting the closed space. That is, when the toe portion and the stepping portion are loaded, the closed space formed by the insole and the recess is compressed, and the air in the closed space is discharged from the air flow path to the outside. . At this time, air in the closed space flows into the shoe by allowing air to flow between the shoe and the closed space. Thereafter, when the load on the toe portion and the stepping portion is removed and the closed space is restored, outside air flows into the closed space from the air flow path, and air in the shoe flows into the closed space. . By repeating these steps, air in the shoe is circulated to prevent stuffiness. Since the other end of the air flow path is opened on the back surface of the arch portion that is not grounded, when outside air flows into the closed space from the air flow path, water, sand, etc. It is hard to penetrate.

  The shape of the ventilation portion is not limited as long as air can be circulated, such as a notch shape, a through hole, and a slit-shaped gap.

  The shoe sole according to claim 2 is characterized in that the buffer plate is tilted to the toe side. According to the shoe sole of claim 2, since the toe part and the stepping part are sequentially weighted from the heel side toward the toe side during walking, the tilting of the buffer plate toward the toe side causes the It becomes easy to bend a buffer board and can improve cushioning properties at the time of walking.

  The shoe sole according to claim 3 is characterized in that the air flow path is closed with a cloth material having air permeability and waterproofness. According to the shoe sole of the third aspect, it is possible to prevent water from entering from the outside while allowing air to enter and exit through the air flow path.

  The shoe sole according to claim 4 is characterized in that the ventilation portions are arranged in a staggered manner by shifting the positions of the ventilation portions of the adjacent buffer plates.

  According to the shoe sole of claim 4, the insole can be evenly supported by the buffer plate by arranging the ventilation portions where the rigidity of the buffer plate is lowered in a staggered manner.

  A shoe according to claim 5 comprises the shoe sole according to any one of claims 1 to 4, wherein an insole is disposed on the upper surface of the sole, and the insole corresponds to the stepping portion of the shoe sole. A portion to be made softer than other portions, a plurality of vent holes are formed at positions corresponding to the concave portions of the shoe sole, and an insole is disposed on the upper surface of the insole. The insole is characterized in that a vent hole is formed in a position corresponding to each vent hole in the insole.

  In the shoe according to the fifth aspect, by forming a portion corresponding to the stepped portion of the shoe sole softer than other portions, the shoe can be easily bent in accordance with the movement of the foot during walking. Moreover, since the inside of the shoe and the closed space are communicated with each other by the plurality of air holes formed in the insole and the insole, as described in the shoe sole of the above-mentioned claim 1 The air in the shoe is circulated to prevent stuffiness. The shoes include both women's shoes and men's shoes.

  The shoe according to claim 6 is configured such that an insole is attached to the upper surface of the insole, and the air hole of the insole is provided between the insole and the insole, and the insole The cloth material is arranged so as to straddle both the range in which the vent hole is provided, and the cloth material is adhered to the insole or the insole only on one side.

  In the shoe according to claim 6, since the insole and the insole do not stick to each other in the portion where the cloth material is arranged, air can flow between the insole and the insole. Thereby, even if the position of the vent hole between the insole and the insole is shifted, the insole is interposed through the gap between the insole and the insole in the portion where the cloth material is disposed. It is possible to ensure the air circulation between the vent hole and the vent hole of the insole.

  The shoe sole of claim 1 is excellent in versatility because it can be used in common for models with different heel heights, and costs such as a mold cost compared to the case of manufacturing the shoe soles according to the heel height. You can go down. And the foot feels good and it is hard to get stuffy, and water does not penetrate into the shoe through the air flow path, so it is comfortable to wear, and the impact during walking is eased and it is easy to walk and fatigue. Provision becomes possible.

  The shoe sole of claim 2 can provide a shoe excellent in cushioning properties during walking.

  The shoe sole according to claim 3 prevents intrusion of water or the like in the air flow path without being obstructed by the entry / exit of air, so that the wearer feels uncomfortable feeling due to the entry of water or the like into the shoe. Therefore, it is possible to provide a comfortable and comfortable shoe without being stuffy.

  The shoe sole of claim 4 increases the sense of stability of the shoe and makes it possible to provide a comfortable shoe.

  The shoe according to claim 5 is not easily stuffy, and water or the like does not enter the shoe through the air flow path and does not cause discomfort to the wearer. Can be worn on. Moreover, when walking, it bends well with the movement of the foot, and the shock when the foot reaches the ground is reduced, so it is easy to walk and less fatigue.

  In the shoe of claim 6, even if the vent holes between the insole and the insole are displaced, air flows between the closed space of the shoe sole and the inside of the shoe. In addition, since it is not necessary to process the insole, and high accuracy is not required for attaching the insole, it is possible to manufacture shoes that satisfy a predetermined level even if not skilled.

  Hereinafter, embodiments of a shoe sole having a heel and a shoe having the shoe sole according to the present invention will be described with reference to the drawings.

  The shoe sole 1 according to the present embodiment is used for women's shoes with heels, and is integrally formed into a plate shape using a rubber material. The rubber materials used were natural rubber (NR) 32% by weight, styrene butadiene rubber (SBR) 59% by weight, butadiene rubber (BR-01) 5% by weight, carbon masterbatch (CH51). It is a soft rubber material in which 31.7% by weight of white carbon filler is further added to the compound added with 5% by weight.

  As shown in FIGS. 1A to 1C, the shoe sole 1 is composed of four parts, a toe part 2, a stepping part 3, an arch part 4, and a heel part 5, and extends from the arch part 4 to the heel part 5. Is formed so that the thickness gradually decreases toward the rear side (in the direction from the toe side toward the heel side).

  The toe portion 2 and the stepping portion 3 have a thickness of about 4 mm, and the recess 6 is formed by making the cross-sectional shape along the shoe width direction concave. The recess 6 forms a closed space when an insole described later is attached to the upper surface of the shoe sole and the upper portion is covered. For the insole, insole, upper, and finished shoes described below, the parts corresponding to the above four parts (toe part 2, stepping part 3, arch part 4 and heel part 5) of these soles are The same designation is used and the same symbol is used.

  A plurality of buffer plates 7 that exhibit cushioning properties when bent are formed in the recess 6 at equal intervals so as to partition the recess 6 in the shoe length direction. Each buffer plate 7 is provided over the inner width of the concave portion 6 in the shoe width direction, and is inclined to the toe side at an angle of about 50 °, and its height is substantially equal to the depth of the concave portion 6. I'm doing it.

  Further, each buffer plate 7 is provided with a ventilation portion 8 by forming slit-like gaps at one place or a plurality of places, thereby allowing air to flow in the shoe length direction in the recess 6. These ventilation parts 8 are arranged in a staggered manner by shifting their positions with respect to the ventilation parts 8 of the adjacent buffer plates 7. Thus, by arranging the ventilation portions 8 where the rigidity of the buffer plate 7 is lowered in a staggered manner, the insole can be evenly supported by the buffer plate 7 and the stability of the shoe can be increased. The buffer plate 7 has a thickness of about 1.5 mm and is easily bent. However, by providing the buffer plate 7 with a narrow pitch of about 3.3 mm, both stability and cushioning are ensured.

  The arch portion 3 is provided with two air flow passages 9 that allow the air to enter and exit from the bottom of the shoe sole in the recess 6. Each air flow path 9 includes a through hole 10 drilled in the thickness direction of the shoe sole 1 and a ventilation groove 11 formed in the shoe length direction on the upper surface of the shoe sole and communicating the through hole 10 and the recess 6. These air flow paths 9 are provided so as to be symmetrical in the shoe width direction. Each through hole 10 has a stepped portion 28 with a large diameter on the upper surface side of the shoe sole and a predetermined depth (FIG. 1 (c)), and the bottom of each stepped portion 28 has air permeability and waterproofness, respectively. A cloth material 12 having both of the above is attached. Thus, by closing the air flow path 9 with the cloth material 12 having air permeability and waterproofness, water, sand, etc. from the outside can be obtained without hindering the air flow between the outside and the recess 6. Is prevented (also called entrance processing).

  The flange portion 5 is formed in a flat shape without irregularities so that the heel can be easily fixed.

  The shoe sole 1 having such a configuration is formed of a soft rubber material and has a reduced thickness, and thus has excellent flexibility, and can be commonly used for models having different heel heights. That is, as shown in FIG. 2, if the heel height is different, the degree of inclination of the arch portion 4 is changed to have a different shoe sole shape, but the shoe sole 1 has excellent flexibility, so This is because it can be bent according to the shape. In addition, since the thickness is small, it is light and the shoes can be lightened. In particular, in this embodiment, since the thickness is reduced from the arch portion 4 to the flange portion 5, further weight reduction is achieved. In addition to these features, it is made of a soft rubber material, making it less slippery than the light bottom of synthetic leather. It has the feature of excellent absorption.

  In order to confirm the impact resistance and anti-slip property of the sole 1, a request was made to the Japan Spinning Inspection Association to perform a drop impact test and a slip resistance test of the weight, and the performance was compared with the light sole.

From the results of Table 6, it was confirmed that the rubber of the shoe sole 1 of the present embodiment showed higher tear strength and tear elongation than the rubber of the conventional shoe sole, and had excellent tear strength. .

  Next, the ladies' shoes 13 provided with the shoe sole 1 of the said embodiment are demonstrated.

  As shown in the perspective view of FIG. 3A and the cross-sectional view of the bottom portion of FIG. 3B, the upper 14 of the women's shoes 13 is in a state where the lower edge is wound around the back of the midsole 15. It is attached to the insole 15. The shoe sole 1 is bonded to the back surface of the insole 15, and an insole 19 is disposed on the upper surface of the insole 15 to improve comfort. A heel 18 made of hard resin is attached to the back surface of the heel 5 of the shoe sole 1. The heel 18 is bonded to the back surface of the collar portion 5 and is firmly fixed by nailing from the upper surface side of the midsole 15.

  The upper 14 is a material obtained by cutting a material such as natural leather, synthetic leather, or fabric cut with a punching die and a back material. The toe portion 2 has a reinforcing material called a tip (not shown). However, a reinforcing material (not shown) called a counter is arranged between the front material and the back material in the collar portion 5.

  As shown in FIG. 4A, the insole 15 is formed by cutting a board material such as leather or pulp into a shoe shape, and the toe portion 2, the arch portion 4 and the heel portion 5 are made of shoes. In order to ensure stability, rigidity is provided, and in order to ensure ease of walking, the stepping portion 3 is softer than other portions and is easily bent. A plurality of ventilation holes 16 are provided through the toe portion 2 and the stepping portion 3, and a substantially rectangular shank 17 that is long in the shoe length direction is attached to the center of the shoe width direction on the back of the arch portion 4. Yes.

  Since the shoe sole 1 is excellent in flexibility, the shoe sole 1 is attached according to the shape of the back surface of the midsole 15 without being bent with an excessive force.

  As shown in FIG. 4B, the insole 19 has a structure in which a synthetic leather 21 is laminated on an elastic urethane sponge 20 and a synthetic leather sheet is laminated on a urethane sheet. The inside of the arch part 4 has a shape with a slight bulge on the outside. At the end of the toe part 2 and the stepping part 3 and the inside of the arch part 4 Each is provided with a plurality of air holes 22 and 23 penetrating therethrough. The respective vent holes 22 of the toe portion 2 and the stepping portion 3 are in positions corresponding to the respective vent holes 16 provided in the midsole 15.

  A double-sided seal is attached to the entire back surface of the insole 19, and the backing 24 of the double-sided seal is peeled off (see FIG. 4 (c)), and the footrest (the sole of the sole) In order to improve the feel), an arch cushion 25 that supports the arch of the foot is attached, and a small piece of the cloth material 26 is attached to the back of the stepping portion 3 and attached to the upper surface of the midsole 15.

  The arch cushion 25 is made of foamed latex, has a generally rhombus shape in plan view, and has a substantially triangular cross-sectional shape along the shoe width direction.

  The cloth material 26 has a substantially rectangular shape, and is arranged so as to extend over both the range in which the vent hole 22 of the insole 19 is provided and the range in which the vent hole 16 of the insole 15 is provided (see FIG. 5). ). In this way, in the portion where the cloth material 26 is attached, the insole 15 and the insole 19 do not stick to each other, and air can flow between the insole 15 and the insole 19. For this reason, even if the positions of the vent holes 16 and 22 between the insole 15 and the insole 19 are shifted, the intermediate portion 15 and the insole 19 in the portion where the cloth material 26 is disposed, Air circulation is ensured between the air holes 16 in the bottom 15 and the air holes 22 in the insole 19. Therefore, some errors that occur when the insole 15 and the insole 19 are processed or the insole 19 is attached can be absorbed.

  The insole 19 is attached after the shoe sole 1 or the heel 18 is fixed, and the volume is not impaired and the cushioning property is maintained. In other words, there is a case where the insole is attached to the upper surface of the insole in advance, and the insole is fixed. As a result, the volume decreases and the cushioning property decreases. Therefore, by attaching the insole 19 after fixing the sole 1 and the heel 18, the volume is not impaired and the original cushioning property can be maintained.

  Next, the operation of the women's shoes 13 will be described.

  If this shoe is worn, the buffer plate 7 of the recess 6 of the shoe sole 1 is bent, and the cushioning property of the buffer plate 7 and the rubber cushioning property make the foot feel soft and comfortable to wear.

  And if it walks, since the excellent flexibility of the shoe sole 1 and the stepping part 3 of the insole 15 are formed softly, a shoe will bend flexibly in the stepping part 3, and it will be very easy to walk. Further, when the weight is applied to the shoes during walking, the closed space 27 formed by the insole 15 and the concave portion 6 of the shoe sole 1 shown in FIG. Then, the air in the closed space 27 is pushed out into the shoe through the vent holes 16 and 22 between the insole 15 and the insole 19 and is discharged to the outside through the air flow path 9 in the shoe sole 1. Then, as the weight moves to the other leg, the closed space 27 is gradually restored, and along with this restoration, air flows from the shoe into the closed space 27 and outside air flows into the closed space 27 through the air flow path 9. . By repeating this while walking, air in the shoe is circulated, and stuffiness is prevented. Moreover, since the shock at the time of walking is absorbed by the buffer plate 7, the burden on the knee or the like can be reduced, and since the shoe sole 1 is thin, the shoes are lightened and are not tired even when walking for a long time. And since the shoe sole 1 is formed of a soft rubber material, it has a good grip and is difficult to slip, and can prevent a fall due to a slip or the like.

  As shown in FIG. 5B, by changing the height and shape of the heel 18 ', it is possible to manufacture women's shoes having different styles while having a common shoe sole. Further, in the shoe sole 1, the buffer plate 7 can be tilted backward toward the buttocks 5 side. However, during normal walking, the buffer plate 7 is loaded from the heel side toward the toe side. It is easier to bend when it is tilted forward, and cushioning during walking can be improved. The above embodiment relates to the women's shoes 13, but needless to say, it can be applied to men's shoes.
