Description

  The present invention relates to an outsole plate structure for sports shoes, and more particularly, to an improved structure for enabling quick turns as a sports shoe.

  Japanese Patent Application Laid-Open No. 2012-61308 discloses that in a sole of a spike shoe such as a soccer shoe, an elastic flex area is provided at a position passing through a stud disposed in a forefoot region, thereby ensuring a traction force by the stud and a forefoot portion. It is described that the flexibility of the region is increased (see paragraphs [0023] to [0026] and [0049] to [0050] of the same publication and FIGS. 2 to 8). Also, in Japanese Patent No. 4935813, in the sole of a spiked shoe such as a soccer shoe or a rugby shoe, a creat is formed in a region that passes through the first intercostal joint and is inclined obliquely forward from the inner shell side to the outer shell side. In addition to forming a high bend area, and placing creats on the front and back of the high bend area, the sole forefoot was made easier to bend, enabling high-efficiency dash and constant-speed running with high running efficiency. (See paragraphs [0003] and [0019] to [0022] and FIGS. 5 to 9 of the publication).

  In the publications described above, the main purpose is to improve the flexibility or flexibility of the sole forefoot unit alone, and attention is paid only to the movement in the front-rear direction during exercise. However, in sports such as soccer and rugby, lateral movement is also important, and a quick turn (direction change) is required during exercise.

  Therefore, the inventor of the present application first paid attention to the movements of the legs and legs during the turn of the person performing the turn. In the case of a turn, usually, an operation of kicking out in a direction opposite to the direction in which the turn is performed is performed with the legs and feet on the opposite side to the direction in which the turn is performed (traveling direction). In this case, in order to increase the ground reaction force in the direction in which the turn is made, the person who makes the turn makes the leg in the direction to make the turn while ensuring the grip force by sufficiently grounding the bottom surface of the outsole to the ground. It is tilted. As a result of analyzing the movement of the person performing the turn, in order to realize a quick turn, the grip force with respect to the ground on the bottom of the outsole is large and the inclination angle of the leg in the direction of performing the turn is large. It has been found preferable.

  On the other hand, in the conventional sole structure, ribs extending in the front-rear direction from the sole middle foot region to the sole buttock region are formed on the outsole so that the sole middle foot region does not bend and twist (for example, (Refer FIG. 3 of Unexamined-Japanese-Patent No. 2012-61308). That is, in the conventional sole structure, when the leg is inclined during the turn, the outsole cannot be deformed according to the movement of the joint in the midfoot area of the foot of the person performing the turn. For this reason, in order to secure a ground contact area between the bottom surface of the outsole and the ground, that is, a gripping force, the means taken by the person who performs the turn is substantially limited to bending the ankle (varus). In this case, because the gripping force of the outsole against the ground is not sufficient, the ground reaction force when kicking with the legs and feet on the opposite side to the direction of the turn cannot be obtained, and as a result, a quick turn is made I could not.

  The present invention has been made in view of such a conventional situation, and the problem to be solved by the present invention is to make a quick turn by sufficiently obtaining a ground reaction force in the direction of turning. We are trying to provide a possible outsole plate structure for sports shoes.

  An outsole plate structure for sports shoes according to the present invention includes an outsole plate body extending from a forefoot region to a buttocks region of a wearer's foot, and a toe ball portion of the foot on the bottom surface of the outsole plate body Grooves are formed in a triangular area formed by connecting positions corresponding to the area, the child ball part (small finger ball part) area, and the distance projection part of the rib, or in the interior thereof (see claim 1).

  According to the present invention, a groove is formed in a triangular area formed by connecting positions corresponding to the toe ball part area, the phalanx part part area, and the distance projection part of the rib, or a part of the inside thereof. By being formed, the flexibility of the triangular region is improved. Therefore, the thumb ball region of the outsole plate main body is easily twisted with respect to the hip region, in other words, the middle foot region of the outsole plate main body is likely to rotate. As a result, when making a turn, the bottom surface of the outsole plate body can be sufficiently grounded to the ground, the gripping force against the ground can be increased, and the inclination angle of the leg in the direction of turning is increased. it can. In this way, a sufficient ground reaction force in the direction in which the turn is made can be obtained, and a quick turn can be realized.

  In the present invention, the groove extends obliquely rearward from the outer side toward the inner side (see claim 2). In this case, the flexibility (that is, the ease of twisting) of the thumb ball region of the outsole plate body with respect to the buttocks region can be further improved, and the rotation of the middle foot region of the outsole plate body can be further promoted. As a result, the ground reaction force in the direction of turning can be increased, and a quicker turn can be realized.

  In the present invention, the groove extends to the inner edge of the outsole plate body (see claim 3). In this case, it is possible to further improve the flexibility (easy to twist) with respect to the buttocks region of the thumb ball region of the outsole plate main body, and to further promote the rotation of the middle foot region of the outsole plate main body, As a result, the ground reaction force in the direction of making the turn can be further increased, and a much quicker turn can be realized.

  In the present invention, a plurality of grooves are formed, and the intervals between the adjacent grooves are gradually increased from the outer side toward the inner side (see claim 4). In this case, when the thumb ball region of the outsole plate main body is bent with respect to the buttocks region, it can be gradually bent stepwise from the rear groove to the front groove, The outsole plate main body can be bent smoothly.

  In the present invention, a plurality of grooves are formed, and the grooves are distributed in a fan shape as starting from a position corresponding to the ball segment region or the vicinity thereof toward the inner shell side (see claim 5). In this case, when the toe ball part region of the outsole plate body is bent with respect to the buttocks region, the outsole plate main body gradually bends around a position corresponding to the child ball part region or the vicinity thereof. The bending of the plate body can be generated more smoothly.

  In the present invention, a high-rigidity region having higher rigidity than that of the triangular region is provided in the outer side region of the triangular-shaped region (see claim 6). In this case, the triangular area is relatively easier to bend than the high rigidity area on the outer side, and the bendability of the triangular area is relatively improved. Thereby, the finger ball part region of the outsole plate body is more easily twisted with respect to the buttock region, and the midfoot part region of the outsole plate body is more likely to rotate.

  In the present invention, the high-rigidity region is disposed from a position corresponding to a region of the midfoot region of the wearer's foot to a position corresponding to a region of the buttocks region (see claim 7). In this case, it is possible to further improve the bendability of the thumb ball region of the outsole plate body with respect to the buttocks region, and to further promote the rotation of the middle foot region of the outsole plate body.

  In the present invention, the sports shoes are cleat shoes (spike shoes) (see claim 8).

  In the present invention, the groove is formed at a location where the creat is not disposed in the creat shoe (see claim 9). In this case, the creat does not hinder the bending of the triangular region, and the bending property of the triangular region can be secured in the creat shoe.

  In the present invention, the creats of the creat shoes are respectively arranged at positions corresponding to the toe ball portion region and the child ball portion region of the wearer's foot, and a plurality of grooves are formed. It is distributed in the shape of a fan as it starts from one of these parts toward the inner shell side (see claim 10).

  In this case, when the toe ball part region of the outsole plate main body is bent with respect to the buttocks region, it is arranged at a position corresponding to the toe ball part region of the foot and a position corresponding to the child ball part region, respectively. Since the bend is gradually bent around any portion between the formed creats, the outsole plate body can be bent smoothly.

  As described above, according to the present invention, a triangular region formed by connecting positions corresponding to the toe ball portion region, the child ball portion region, and the distance projection portion of the rib of the foot, or a groove formed therein is formed. Therefore, the bendability of the triangular area is improved, the thumb ball area of the outsole plate body is easily bent with respect to the buttocks area, and the midfoot area of the outsole plate body is rotated. It is easy to wake up. As a result, when making a turn, the bottom surface of the outsole plate body can be sufficiently grounded to the ground, the gripping force against the ground can be increased, and the inclination angle of the leg in the direction of turning is increased. it can. In this way, the ground reaction force in the direction of turning can be increased, and a quick turn can be realized.

  The outsole plate main body 1 is a thin plate-like member, and a rising portion 1C that rises upward (toward the front side of FIG. 2 and to the right of FIG. 3) along its outer peripheral edge is formed over the entire circumference. A lower outer surface of an upper (not shown) of a sports shoe is fixed to the inner side surface of the rising portion 1C.

  The outsole plate body 1 is preferably composed of a hard elastic member, and specifically, a thermoplastic resin such as thermoplastic polyurethane (TPU), polyamide (PA), polyamide elastomer (PAE), ABS resin, or It is composed of a thermosetting resin such as an epoxy resin or an unsaturated polyester resin.

  A plurality of creats are disposed on the bottom surface 1A of the outsole plate main body 1, and the creats 10, 10 'are provided on the inner side of the forefoot region F, and the creats 11, 11', 11 "are provided on the outer side. The creats 12 and 12 'are respectively disposed in the central portion in the width direction, the creat 13 is disposed on the inner side of the buttocks region H, and the creat 13' is disposed on the outer side. In the back contact side surface 1B, recesses are respectively formed at positions corresponding to these creats.In Fig. 2, reference numerals of the respective recesses are denoted by reference numerals of the respective creeps corresponding to the respective recesses. This is expressed by assigning “a”. These recesses are not essential.

  A groove 2 including a plurality of grooves 21 to 25 is formed on the bottom surface 1 </ b> A of the outsole plate body 1. As shown in FIG. 1, each of the grooves 21 to 25 is distributed in a generally fan shape in the rear (lower side of the figure) side region of the forefoot region F, starting from a portion closer to the outer shell toward the inner shell. Each of the creats is disposed so as not to overlap each other while avoiding each of the creats (see FIG. 1). Each of the grooves 21 to 25 extends while gradually curving from the outer side toward the inner side, and is a groove having a curved shape or a substantially linear shape. The interval between the adjacent grooves is wider in the inner shell side region than in the outer shell side region, and is gradually or stepwise widened from the outer shell side toward the inner shell side.

FIG. 4 is a schematic bottom view showing the positional relationship between the outsole plate structure and the foot skeleton structure according to this embodiment. In the figure, a circular dot-and-dash line region distributed around the _first metatarsal joint MP ₁ between the first heel proximal phalanx PP ₁ and the first heel metatarsal MB ₁ is the phalangeal region. Similarly, a circular dot-and-dash line region distributed around the _fifth metatarsal joint MP ₅ between the _fifth metatarsal bone PP ₅ and the fifth metatarsal bone MB ₅ is a child. This is a fingerball part (little fingerball part) region TE. Further, the distance projection portion ST of the rib CC is indicated by a circular hatched area. In the figure, CU indicates a cubic bone, and NA indicates a scaphoid bone.

The groove 2 is a triangular region TR (dash-dotted line) formed by connecting positions corresponding to the part in the toe ball part region TE of the foot, the part in the child ball part region HE, and the distance projection part ST of the rib CC. (See below). As a preferable example, the triangular region TR shown in FIG. 4 includes a region TE ₁ (refer to a circular hatched region) located on the rear side (lower side of the figure) in the thumb ball region TE and a child ball region HE. Is formed by connecting the central portion of the center portion and the central portion of the distance projection portion ST.

  In the triangular region TR, the groove 2 extends obliquely rearward from the outer side toward the inner side. In this example, the grooves 2 are distributed in a partial region inside the triangular region TR, but may be distributed over the entire region of the triangular region TR. In this example, the groove 2 extends to the inner edge of the outsole plate body 1 (that is, to the upper edge of the rising portion 1C on the inner shell side). May be arranged in front of the inner side edge of the outsole plate body 1 (that is, in front of the rising part 1C on the inner side).

  In this example, the starting point of the groove 2 is arranged outside the triangular region TR in the vicinity of the child ball portion region HE. However, the starting point of the groove 2 is on or within the boundary line of the triangular region TR, or the child ball portion region HE. You may make it arrange | position inside.

  As can be seen from FIG. 4, in the forefoot region F, the inner side creat 10 ′ is at a position corresponding to the thumb ball region TE, and the outer side creat 11 ′ is at a position corresponding to the child ball region HE. In the buttock region H, the inner side cleats 13 are arranged in the vicinity of the distance projection portion ST. The starting point of the groove 2 is arranged at any part between the creats 10 'and 11'. In this example, the starting point of the groove 2 is disposed at a portion between the creat 11 'on the outer side and the creat 12' in the center in the width direction.

  As for the cross-sectional shape of the groove 2, in the inner side area, as shown in FIG. 5, which is a VV line cross section of FIG. 1, each of the grooves 21 to 25 has a substantially triangular shape. As shown in FIG. 6 which is a cross-sectional view taken along the line VI-VI in FIG. 1, each of the grooves 21 to 25 has a substantially arc shape (hatching is omitted in FIGS. 5 and 6). You may make it have the same cross-sectional shape in both the instep side area | regions. In this example, the depth of each of the grooves 21 to 25 is d in the inner side region and the outer side region, but the depth may be changed in both regions.

  As shown in FIG. 4, high rigidity regions 3 </ b> A and 3 </ b> B having higher rigidity than the rigidity of the triangular region TR are provided in the outer side region of the triangular region TR. As shown in FIGS. 1 and 2, the high-rigidity region portion is represented as region portions 3A and 3B on the bottom surface 1A side of the outsole plate body 1, and is represented as region 3 on the sole contact side surface 1B side. These are all the same members. The plate-shaped high-rigidity region portion 3 having an outer peripheral shape as shown in FIG. 2 is used as an insert when the outsole plate main body 1 is formed, so that the high-rigidity region portion is formed on the bottom surface 1A side of the outsole plate main body 1. Region parts 3A and 3B, which are parts of 3 respectively, appear. The high rigidity region 3 is disposed in a region from the outer side region of the midfoot region M of the outsole plate main body 1 to the central portion in the width direction of the buttock region H.

  The high-rigidity region portion 3 is preferably composed of a hard elastic member, and specifically, a thermoplastic resin such as thermoplastic polyurethane (TPU), polyamide (PA), polyamide elastomer (PAE), ABS resin, or It is composed of a thermosetting resin such as an epoxy resin or an unsaturated polyester resin. The high-rigidity region portion 3 may be made of fiber reinforced plastic (FRP) using carbon fiber, aramid fiber, glass fiber or the like as reinforcing fiber and thermosetting resin or thermoplastic resin as matrix resin. Good. The high-rigidity region portion 3 is more rigid than the outsole plate body 1 by using a material different from that of the outsole plate body 1 or by increasing the thickness even if the same material as the outsole plate body 1 is used. Is high.

Next, the function and effect of this embodiment will be described.
In the present outsole plate structure, as described above, positions corresponding to the part in the toe ball part region TE, the part in the child ball part region HE, and the distance projection part ST of the rib CC are connected. By forming the groove 2 in the triangular region TR that can be formed (see FIG. 4), the flexibility of the triangular region TR is improved, and the outsole plate body 1 corresponding to the toe ball region TE of the foot is improved. The region is easily bent with respect to the buttock region H, and the midfoot region M of the outsole plate main body 1 is likely to be prolapsed. Thereby, when making a turn, the bottom surface 1A of the outsole plate body 1 can be sufficiently grounded to the ground, the gripping force against the ground can be increased, and the angle of inclination of the legs in the direction of turning Can be increased. In this way, a sufficient ground reaction force in the direction in which the turn is made can be obtained, and a quick turn can be realized.

  Here, as the vertex on the rear side of the triangular region TR, the focus on the distance projection portion ST is that the load position with respect to the ground is the distance projection portion ST when the foot is strung on the foot region during the turn. It is because it corresponds to. The front side region of the distance projection part ST is formed with a groove 2 to improve the bendability, while the rear side region of the distance projection part ST is not formed with the groove 2 so as to be rigid. In addition, since the creats 13 are disposed, the creats 13 can be stably strung when strung in the heel region of the foot.

  Further, when kicking out in the direction opposite to the direction in which the turn is made, the front foot region F of the outsole plate body 1 on the landing side is used, and at this time, each creat 10 on the inner side of the front foot region F is used. Since the concave surfaces 10b and 10'b are formed on 10 '(see FIG. 1), when the ground is kicked by these creats 10 and 10', the ground can be sufficiently captured by the concave surfaces 10b and 10'b. And the traction effect on the ground can be improved.

  Further, in the present embodiment, the groove 2 extends obliquely rearward from the outer side toward the inner side, so that the heel region of the region corresponding to the thumb ball region TE in the outsole plate body 1 Flexibility (easy to twist) with respect to H can be further improved, and further rotation of the midfoot region M of the outsole plate body 1 can be further promoted. As a result, the ground reaction force in the direction of turning can be increased, and a quicker turn can be realized.

(Easy to twist) can be further improved, and the outsole of the midsole region M of the outsole plate body 1 can be further promoted, whereby the ground reaction force in the direction of turning can be further increased. A quick turn can be realized.

  In this embodiment, a plurality of grooves 2 are formed, and the distance between adjacent grooves 21 to 25 is gradually increased from the outer side toward the inner side, so that the outsole plate body 1, when the region corresponding to the thumb ball region TE is bent with respect to the buttocks region H, the region can be gradually bent from the rear groove 25 to the front groove 21, The outsole plate body 1 can be bent smoothly.

  In the present embodiment, a plurality of grooves 2 are formed, and a position corresponding to the vicinity region of the child ball portion region HE (in this embodiment, a creat 11 ′ at a position corresponding to the child ball portion region HE is further provided). And a position corresponding to the thumb ball region TE in the outsole plate main body 1 by being distributed in a fan-shaped manner starting from the center of the width direction and the creat 12 'in the width direction. When bending with respect to the buttocks region H, since it gradually bends around a position corresponding to the vicinity of the child ball portion region HE, the outsole plate body 1 can be bent more smoothly. Can do.

  Further, in the present embodiment, the high rigidity region 3 having higher rigidity than the rigidity of the triangular region TR is provided in the outer region on the triangular region TR, so that the triangular region TR is located on the outer side. It is easier to bend than the high-rigidity region 3, and the bendability of the triangular region TR is relatively improved. Thereby, in the outsole plate body 1, the region corresponding to the thumb ball region TE is more easily twisted with respect to the buttock region H, and the middle foot region M of the outsole plate body 1 is further rotated. It has become easier.

  In the present embodiment, the high-rigidity region 3 is disposed in the region from the outer side region of the midfoot region M of the outsole plate body 1 to the center in the width direction of the buttock region H. In the outsole plate body 1, the flexibility of the region corresponding to the thumb ball region TE with respect to the heel region H can be further improved, and the rotation of the midfoot region M of the outsole plate body 1 can be further promoted.

It is. This is because the rigidity of the triangular region TR can be relatively reduced by forming the groove 2 in the triangular region TR.

  As described above, the present invention is useful for an outsole plate structure for sports shoes, and is particularly suitable for sports shoes that require a quick turn during exercise.
