Description

  The present invention relates to a golf shoe. Specifically, the present invention relates to an improvement in the outsole of a golf shoe.

  When a golfer hits a golf ball, the golf ball is addressed so that the line connecting the right and left toes is substantially parallel to the target direction. In the address of a right-handed golfer, the left foot is located on the front side in the target direction and the right foot is located on the rear side in the target direction. At the address, the golf club head is located near the golf ball. From this state, the golfer starts taking back and swings the head backward and then upwards. The position where the head is most swung up is the top position. A downswing is started from the top position. The start of the downswing is called “turning back”. After turning back, the head is swung down and the head collides with the golf ball (impact). After the impact, the golfer swings the golf club forward and then upwards to reach the finish.

  From the top position to the finish, a great force is applied to both legs of the golfer. This force can cause the golf shoe to slip with the ground. When slip occurs, the swing form is disturbed and a miss shot occurs. In particular, slip is likely to occur before and after turning back and before and after impact.

  There are golf shoes having spike pins made of metal or ceramic on the bottom surface. Spike pins prevent slipping. However, in this golf shoe, spike pins damage the lawn on the green, the floor of the clubhouse, the road surface of the walking path provided in the golf course, and the like. Many golf courses prohibit the use of golf shoes with spike pins. Golf shoes with spike pins have a feeling of being pushed up from the bottom and are not comfortable for golfers. Golf shoes with spike pins have not been widely used in recent years.

  Golf shoes in which a protrusion made of rubber or synthetic resin is provided on the bottom instead of the spike pin are widely used. In this golf shoe, the lawn or the like is rarely damaged. This golf shoe is excellent in comfort. However, this golf shoe has insufficient anti-slip performance as compared with a golf shoe having spike pins.

  A right-handed golfer makes a body turn from the top position to the finish with the left foot as the axis. At the same time, the golfer kicks the ground with his right foot and transmits the force to the golf ball. Right-handed golfers use the left foot as the axle and the right foot as the kick. For left-handed golfers, use the right foot as the axle and the left foot as the kick. Japanese Patent Application Laid-Open No. 2001-299406 discloses a golf shoe in which a difference in roles between a shaft foot and a kick foot is considered.

  A golf shoe according to an embodiment of the present invention includes a shaft foot shoe and a kick foot shoe. 1 and 2 show a shoe 2 for a foot. This axle foot shoe 2 is worn by a right-handed golfer. The shaft shoe for the left-handed golfer has a shape obtained by inverting the shape of the shaft shoe 2 shown in FIG.

  The shaft foot shoe 2 includes an upper 4 and a sole 6. The sole 6 includes an insole 8, a midsole 10 and an outsole 12. In FIGS. 1 and 2, what is indicated by a symbol X is the width direction, what is indicated by a symbol Y is a length direction, and what is indicated by a symbol Z is a height direction. In FIG. 2, what is indicated by a symbol LL is a length line. The length line LL is the longest line that can be drawn in the outline of the outsole 12 in the bottom view.

  A known material is used for the upper 4. Natural leather, synthetic leather, artificial leather, woven fabric, or the like can be used for the upper 4. An inner material may be attached to the inner surface of the upper 4. A typical inner material is a woven fabric. A moisture-permeable waterproof material may be used as the inner material. A typical moisture-permeable waterproof material is a bootie made of GORE-TEX (registered trademark).

  The insole 8 is laminated with the midsole 10. The insole 8 is made of woven fabric or foamed synthetic resin. The insole 8 is in contact with the foot. The insole 8 contributes to the slipping of the foot in the operation of wearing the axial foot shoe 2. The insole 8 further contributes to comfort. The insole 8 may not be provided.

  The midsole 10 is made of a foam. Preferably, the midsole 10 includes a number of closed cells. At the time of landing, the midsole 10 undergoes compression deformation. The impact is absorbed by this compression deformation. A preferred base polymer in the midsole 10 is an ethylene-vinyl acetate copolymer (EVA). From the viewpoint of impact absorption, the midsole 10 has a hardness of preferably 70 or less, particularly preferably 65 or less. From the viewpoint of strength, the hardness is preferably 40 or more. The hardness is measured with a type A durometer in accordance with the rules of “JIS K 6253”.

  The outsole 12 is located below the midsole 10. Outsole 12 is joined to midsole 10. Bonding can be accomplished with an adhesive. The outsole 12 is made of a crosslinked rubber. Preferred base rubbers include natural rubber (NR), isoprene rubber (IR), butadiene rubber (BR), styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR) and urethane rubber. A synthetic resin or an elastomer may be used for the outsole 12. The outsole 12 does not include bubbles. From the viewpoint of wear resistance, the hardness of the outsole 12 is preferably 70 or more, and particularly preferably 75 or more. From the viewpoint of followability to foot deformation, the hardness is preferably 85 or less, and particularly preferably 80 or less. The hardness is measured with a type A durometer in accordance with the rules of “JIS K 6253”.

  FIG. 2 shows the bottom surface of the outsole 12. In FIG. 2, the left side is the inside, the right side is the outside, the upper side is the toe side, and the lower mold is the heel side. The outsole 12 includes a base 14 and two first protrusion groups 16. Each first projection group 16 is located on the inner side of the length line LL and on the toe side of the arch 18. The number of the first protrusion groups 16 may be 1 or 3 or more. The number of first protrusion groups 16 is preferably 6 or less.

  The outsole 12 further includes a number of protrusions 20 that do not belong to the first protrusion group 16. Each protrusion 20 protrudes from the base 14. The protrusions 20 contribute to the anti-slip performance of the foot shoe 2. From the viewpoint of anti-slip performance, the height of the protrusion 20 is preferably 2 mm or more, and particularly preferably 4 mm or more. From the viewpoint of the rigidity of the protrusion 20, the height of the protrusion is preferably 15 mm or less, and particularly preferably 10 mm or less.

  FIG. 3 is an enlarged bottom view showing a part of the outsole 12 of FIG. FIG. 3 shows one first protrusion group 16. The first protrusion group 16 includes three elongated protrusions 22. Specifically, the first protrusion group 16 includes a first elongated protrusion 22a, a second elongated protrusion 22b, and a third elongated protrusion 22c. The first protrusion group 16 may include two elongated protrusions 22. The first protrusion group 16 may include four or more elongated protrusions 22. The number of the elongated protrusions 22 in the first protrusion group 16 is preferably 10 or less. Each elongated protrusion 22 has a bottom surface 24 (see FIGS. 4 and 5), a toe side end surface 26, a heel side end surface 28, and two side surfaces 30.

  In FIG. 3, arrow A1 represents the extending direction of the first elongated protrusion 22a, arrow A2 represents the extending direction of the second elongated protrusion 22b, and arrow A3 represents the extending direction of the third elongated protrusion 22 Represents. These elongated protrusions 22 extend along the direction toward the inside toward the toe side. The toe side end surface 26 is substantially orthogonal to the arrow (A1, A2 or A3).

  FIG. 4 is an enlarged cross-sectional view of the elongated protrusion 22 along the extending direction. In FIG. 4, the dimension of the elongated protrusion 22 in the extending direction is indicated by a symbol Lp. FIG. 5 is an enlarged cross-sectional view of the elongated protrusion 22 along a direction orthogonal to the extending direction. In FIG. 5, the dimension of the elongated protrusion 22 in the direction orthogonal to the extending direction is indicated by a symbol Wp. As is apparent from the comparison between FIGS. 4 and 5, the dimension Lp is sufficiently larger than the dimension Wp.

  According to the knowledge obtained by the present inventor, the axial foot shoe 2 generates the greatest horizontal force before and after turning back. The horizontal force at this time is mainly generated on the inner side of the length line LL and on the toe side of the arch 18. In other words, the position where the force is mainly generated is in the vicinity of the first protrusion group 16. The direction of the horizontal force is a direction toward the inside toward the toe side. In other words, the direction of the horizontal force substantially coincides with the extending direction of the elongated protrusion 22. Since the elongated protrusion 22 has a large dimension Lp in the extending direction, the elongated protrusion 22 is highly rigid in the extending direction. Therefore, even if a horizontal force is applied, the elongated protrusion 22 is unlikely to buckle in the extending direction. On the other hand, since the dimension Wp of the elongated protrusion 22 is sufficiently small, the bottom area of the elongated protrusion 22 is not excessive. Therefore, the elongated protrusion 22 receives the weight of the golfer and pierces the ground. The elongated protrusion 22 suppresses slipping of the foot shoe 2 before and after turning back.

  From the viewpoint of rigidity in the extending direction, the dimension Lp is preferably 8 mm or more, more preferably 10 mm or more, and particularly preferably 12 mm or more. The dimension Lp is preferably 40 mm or less. From the viewpoint of being easily stabbed into the ground, the dimension Wp is preferably 12 mm or less, more preferably 10 mm or less, and particularly preferably 7 mm or less. The dimension Wp is preferably 2 mm or more. When the width of the elongated protrusion 22 changes along the extending direction, the maximum width is the dimension Wp.

  From the viewpoint of slip suppression, the ratio (Lp / Wp) of the dimension Lp to the dimension Wp is preferably 2.5 or more, and particularly preferably 3.0 or more. From the viewpoint of easy pattern design, the ratio (Lp / Wp) is preferably 8.0 or less.

  In FIG. 4, what is indicated by a symbol Hp is the height of the elongated protrusion 22. From the viewpoint that slip is suppressed, the height Hp is preferably 4 mm or more and 10 mm or less.

  As is clear from FIG. 4, the angle θp that the toe side end surface 26 forms with the ground exceeds 90 °. Therefore, the toe side end face 26 is likely to pierce the ground. The toe side end face 26 suppresses slipping of the foot shoe 2 before and after turning back. From the viewpoint of slip suppression, the angle θp is preferably 100 ° or more and 160 ° or less. The angle θp is more preferably 110 ° or more, and particularly preferably 120 ° or more. The angle θp is particularly preferably 150 ° or less.

  In FIG. 3, symbol α1 represents the angle between the length line LL and the arrow A1, symbol α2 represents the angle between the length line LL and the arrow A2, and symbol α3 represents the angle between the length line LL and the arrow A3. Represent. From the viewpoint of slip suppression before and after switching, these angles α1, α2 and α3 are preferably more than 0 ° (degree) and not more than 60 °. These angles α1, α2 and α3 are particularly preferably 15 ° or more. These angles α1, α2 and α3 are particularly preferably 55 ° or less.

  As is apparent from FIG. 3, the three elongated protrusions 22 are arranged radially. Accordingly, the angle α1 is larger than the angle α2, and the angle α2 is larger than the angle α3. According to the knowledge obtained by the present inventor, the direction of the force before and after turning back of the foot shoe 2 shifts from the direction of the arrow A1 to the direction of the arrow A2, and further to the direction of the arrow A3. By arranging the plurality of elongated protrusions 22 in a radial manner, the slip before and after the cut-back is sufficiently suppressed.

  FIG. 6 shows an outsole 32 of a shoe for a kick leg. The material of the outsole 32 is the same as the material of the outsole 12 of the foot shoe 2 shown in FIG. Although not shown, this shoe for a kick foot includes an upper, an insole, and a midsole, like the shoe for a foot shoe 2 shown in FIG. This kick shoe is worn by right-handed golfers. The shoe for a kick leg for a left-handed golfer has a shape obtained by inverting the shape of the shoe for a kick leg shown in FIG.

  In FIG. 6, what is indicated by a symbol X is the width direction, and what is indicated by a symbol Y is the length direction. In FIG. 6, what is indicated by a symbol LL is a length line. The length line LL is the longest line that can be drawn in the outline of the outsole 32 in the bottom view.

  In FIG. 6, the left side is the outside, the right side is the inside, the upper side is the toe side, and the lower mold is the heel side. The outsole 32 includes a base 34 and two second protrusion groups 36. Each of the second projection groups 36 is located on the inner side of the length line LL and on the toe side of the arch 38. The number of the second protrusion groups 36 may be 1 or 3 or more. The number of the second protrusion groups 36 is preferably 6 or less.

  The outsole 32 further includes a number of protrusions 40 that do not belong to the protrusion group. Each protrusion 40 protrudes from the base 34. This protrusion 40 contributes to the anti-slip performance of the shoe for a kick foot. From the viewpoint of anti-slip performance, the height of the protrusion is preferably 2 mm or more, and particularly preferably 4 mm or more. From the viewpoint of the rigidity of the protrusion, the height of the protrusion is preferably 15 mm or less, and particularly preferably 10 mm or less.

  FIG. 7 is an enlarged bottom view showing a part of the outsole 32 of FIG. FIG. 7 shows one second protrusion group 36. The second protrusion group 36 includes three elongated protrusions 42. Specifically, the second protrusion group 36 includes a fourth elongated protrusion 42a, a fifth elongated protrusion 42b, and a sixth elongated protrusion 42c. The second protrusion group 36 may include two elongated protrusions 42. The second protrusion group 36 may include four or more elongated protrusions 42. The number of the elongated protrusions 42 in the second protrusion group 36 is preferably 10 or less. Each elongated protrusion 42 has a bottom surface 44 (see FIGS. 8 and 9), a toe side end surface 46, a heel side end surface 48, and two side surfaces 50.

  In FIG. 7, the arrow B1 represents the extending direction of the fourth elongated protrusion 42a, the arrow B2 represents the extending direction of the fifth elongated protrusion 42b, and the arrow B3 represents the extending direction of the sixth elongated protrusion 42c. Represents. These elongated protrusions 42 extend along the direction toward the inside toward the heel side. The heel side end surface 48 is substantially orthogonal to the arrow (B1, B2 or B3).

  FIG. 8 is an enlarged cross-sectional view of the elongated protrusion 42 along the extending direction. In FIG. 8, the dimension of the elongated protrusion 42 in the extending direction is indicated by a symbol Lk. FIG. 9 is an enlarged cross-sectional view of the elongated protrusion 42 along a direction orthogonal to the extending direction. In FIG. 9, the dimension of the elongated protrusion 42 in the direction orthogonal to the extending direction is indicated by the symbol Wk. As is apparent from the comparison between FIGS. 8 and 9, the dimension Lk is sufficiently larger than the dimension Wk.

  According to the knowledge obtained by the present inventor, in the shoe for a kick foot, the largest horizontal force is generated before and after the impact. The horizontal force at this time is mainly generated on the inner side of the length line LL and on the toe side of the arch 38. In other words, the position where the force is mainly generated is in the vicinity of the second protrusion group 36. The direction of the horizontal force is a direction toward the inside toward the heel side. In other words, the direction of the horizontal force substantially coincides with the extending direction of the elongated protrusion 42. Since the elongated protrusion 42 has a large dimension Lk in the extending direction, the elongated protrusion 42 is highly rigid in the extending direction. Accordingly, the elongated protrusion 42 is unlikely to buckle in the extending direction even when receiving a horizontal force. On the other hand, since the dimension Wk of the elongated protrusion 42 is sufficiently small, the bottom area of the elongated protrusion 42 is not excessive. Accordingly, the elongated protrusion 42 receives the weight of the golfer and pierces the ground. The elongate protrusion 42 suppresses the slip of the shoe for a kick foot before and after the impact.

  From the viewpoint of rigidity in the extending direction, the dimension Lk is preferably 8 mm or more, more preferably 10 mm or more, and particularly preferably 12 mm or more. The dimension Lk is preferably 40 mm or less. From the viewpoint of being easily pierced into the ground, the dimension Wk is preferably 12 mm or less, more preferably 10 mm or less, and particularly preferably 7 mm or less. The dimension Wk is preferably 2 mm or more. When the width of the elongated protrusion 42 changes along the extending direction, the maximum width is the dimension Wk.

  From the viewpoint of slip suppression, the ratio (Lk / Wk) of the dimension Lk to the dimension Wk is preferably 2.5 or more, and particularly preferably 3.0 or more. From the viewpoint of easy pattern design, the ratio (Lk / Wk) is preferably 8.0 or less.

  In FIG. 8, what is indicated by a symbol Hk is the height of the elongated protrusion 42. In light of suppression of slip, the height Hk is preferably 4 mm or greater and 10 mm or less.

  As is apparent from FIG. 8, the angle θk formed by the heel side end surface 48 with the ground exceeds 90 °. Therefore, the heel side end face 48 is likely to pierce the ground. The heel side end surface 48 suppresses the slip of the boot for the foot kick before and after the impact. From the viewpoint of slip suppression, the angle θk is preferably 100 ° or more and 160 ° or less. The angle θk is more preferably 110 ° or more, and particularly preferably 120 ° or more. The angle θk is particularly preferably 150 ° or less.

  In FIG. 7, the symbol β1 represents the angle between the length line LL and the arrow B1, the symbol β2 represents the angle between the length line LL and the arrow B2, and the symbol β3 represents the angle between the length line LL and the arrow B3. Represent. From the viewpoint of slip suppression before and after impact, these angles β1, β2, and β3 are preferably more than 0 ° and 60 ° or less. These angles β1, β2, and β3 are particularly preferably 15 ° or more. These angles β1, β2, and β3 are particularly preferably 55 ° or less.

  As is apparent from FIG. 7, the three elongated protrusions 42 are arranged radially. Thus, angle β1 is greater than angle β2, and angle β2 is greater than angle β3. According to the knowledge obtained by the present inventor, the direction of the force before and after the impact of the shoe for a kick leg shifts from the direction of arrow B1 to the direction of arrow B2, and further shifts to the direction of arrow B3. By arranging the plurality of elongated protrusions 42 in a radial manner, the slip before and after the impact is sufficiently suppressed.

  The golf shoe may be composed of a shaft foot shoe 2 having the first projection group 16 and a kick foot shoe not having the second projection group 36. In this golf shoe, slip before and after turning back can be suppressed.

  The golf shoe may include a shaft foot shoe 2 that does not have the first projection group 16 and a kick foot shoe that has the second projection group 36. In this golf shoe, slip before and after impact can be suppressed.
