Description

  The present invention relates to athletic shoes, particularly tennis shoes.

  In sports, the athlete's feet require considerable force, not only to change the posture and direction, but also to stop suddenly after running. So, on the one hand, you can prevent injuries while increasing the comfort and cushioning of your feet, and on the other hand, you can add shoes to the sports characteristics associated with the sport to optimize the dynamics of the athlete's movement. Appropriate sports shoes that can be adapted are needed.

  In the case of tennis, forward and side movements are very frequent with many turnarounds, and such movement is a major technical challenge for the player's athletic ability. Presently available shoes do not allow optimal adaptation to the physiological and movement characteristics of the tennis player's movements.

  Patent document 1 is disclosing the athletic shoe provided with the outsole which has the vertical and horizontal bending line which divides | segments an outsole into several zones. The performance of such shoes is not optimized.

  The invention will be better understood from the following description of an athletic shoe according to its principles, presented as a non-limiting example with reference to the accompanying drawings, and other advantages of the invention will become more apparent It will be.

FIG. 1 is a bottom view of a part of a shoe according to the present invention. FIG. 2 is a longitudinal sectional view of the shoe portion of FIG. 1 taken along the plane II-II of FIG. 3 is a cross-sectional view of the shoe of FIG. 1 along the plane III-III of FIG. FIG. 4 is a top view of a midsole belonging to the shoes of FIGS. FIG. 5 is a bottom view similar to FIG. 1 of a portion of a shoe according to one alternative of the present invention. FIG. 6 is a bottom view of the insole of FIGS. 7 is a longitudinal sectional view taken along the plane VII-VII of the insole of FIG.

  The athletic shoe 1 is partially shown in FIGS. More specifically, the shoe 1 is configured for tennis competition.

  As shown in FIGS. 2 and 3, the shoe 1 includes an outsole 3 suitable for contact with the ground, and an insole shown in FIGS. 6 and 7 provided to be positioned under an athlete's foot P. A midsole 5 inserted between the outsole 3 and the insole in the vertical direction. The shoe 1 further includes an upper, a tongue, and a tightening member that are not shown.

  The shoe 1 defines a longitudinal axis X-X ′ that extends generally between a front end 10 and a rear end 12 of the shoe 1. In the following description, the adjectives “front” and “rear” are used with respect to axis X-X ′ and front end 10 and rear end 12.

  Similarly, the shoe 1 defines a transverse direction YY ′ perpendicular to the axis XX ′, which is on the right side in FIG. 1 and on the inside I of the foot P located on the left side in FIG. It extends between the left side in FIG. 1 and the outside E located on the right side in FIG. The inside of the foot P is the side facing the vertical central axis of the human body. In the following description, the adjectives “in” and “out” are used with respect to the transverse direction Y-Y ′.

  The foot P has a thumb 21 located inside the foot P, and second, third, fourth, and second fingers numbered 22, 23, 24, and 25 respectively from the inside to the outside of the foot. It has 5 toes, including 5 fingers.

  As shown in FIG. 1, the outsole 3 is divided into three transverse zones along the longitudinal axis X-X ′.

  The first zone 3A, called the front zone, extends between the front end 10 and the region of the shoe 1 corresponding to the base of the athlete's foot P. Accordingly, the front zone 3A generally corresponds to the zone of the outsole 3 provided so as to be at least partially positioned under the athlete's toes.

  The distance between the front end 10 and the rear end 12 is defined as the total length of the outsole 3.

  The front zone 3A extends from the front end 10 over a distance between 10-30% of the total length of the outsole 3A.

  The second zone 3B, called the intermediate crossing zone, is below the area of the foot P located between the base of the toes and the front end P1 of the arch, which is the arch area of the foot P, also called the “plantar arch”. , At least partially extending. This region is the most full-bodied portion of the foot P, and is subjected to great stress when playing sports, more specifically when playing tennis. Most of the weight rests on this part of the foot P when the player is ready to move before hitting.

  The intermediate zone 3B extends over a distance of 15-25% of the total length of the outsole 3 from the front zone 3A.

  The outsole 3 includes a third zone 3 </ b> C called a rear zone, which is provided so as to be located under the region of the foot P extending rearward from the front end P <b> 1 of the arch. The rear zone 3C is provided so as to spread under the sole arch.

  The rear zone 3C extends over a distance between the middle zone 3B and 20-40% of the total length of the outsole 3.

  The outsole 3 can further optionally include a fourth transverse zone 3T provided to lie under the heel. The zone 3T extends rearward from the rear zone 3C to the rear end 12. This zone 3T extends over a distance of 20 to 40% of the total length of the outsole 3 from the rear zone 3C.

  Zone 3A is separated from zone 3B by a first transverse bend line 30 and zone 3B is separated from zone 3C by a second transverse bend line 32. The transverse bending line 30 is provided so as to be entirely located under the base of the toes. The transverse bending line 32 is provided so as to be entirely located under the front end P1 of the arch of the foot P. The bending lines 30 and 32 constitute a band-like portion of the outsole 3 whose flexibility is higher than that of the zones 3A, 3B, and 3C. Flexibility refers to the ability of a member to deform under the action of a bending force. That is, the deformability of the outsole 3 in the bending lines 30 and 32 is higher than the deformability of the outsole 3 in the zones 3A, 3B, and 3C. Thus, the bend lines 30 and 32 allow the zones 3A, 3B, 3C to be articulated relative to each other.

  In this case, the outsole 3 is particularly suitable for holding when playing sports, more specifically, playing tennis. When setting up, the outsole 3 is particularly prepared for the tennis player to wait before hitting a ball by the opponent. In this case, most of the weight is applied to a well-filled region extending between the base of the toes and the front end P1 of the arch. The intermediate transverse zone 3B is particularly stressed in this configuration.

  The player can step on the front zone 3 </ b> A when the player dashes forward to transmit a large impact to the ground via his / her toes. In this case, the flexibility of the front zone 3A with respect to the intermediate crossing zone 3B allows better energy transfer to the ground, thereby increasing the efficiency of the player's forward movement.

  As shown in FIGS. 1 and 2, the outsole 3 is further divided into three longitudinal zones along the horizontal axis Y-Y ′.

  The first longitudinal zone 3 </ b> D called the inner zone extends from the inner edge 34 of the outsole 3 and is provided so as to be at least partially positioned under the big toe 21. The inner zone 3D extends in the front zone 3A, the intermediate zone 3B, and the rear zone 3C.

  The distance between the inner edge 34 and the outer edge 36 is defined as the full width of the outsole 3.

  The inner zone 3D extends over a distance between the inner edge 34 and 20-40% of the total width of the outsole 3.

  The second longitudinal zone 3 </ b> E called the central longitudinal zone is provided so as to be at least partially positioned below the second finger 22 and the third finger 23 of the foot. This zone 3E extends into the front zone 3A and the intermediate zone 3B and reaches the rear zone 3C where it partially expands.

  The central zone 3E extends from the inner zone 3D over a distance between 20-40% of the full width of the outsole 3.

  The third zone 3 </ b> F, called the outer zone, extends from the outer edge 36 of the outsole 3 and is provided so as to be at least partially positioned below the fourth and fifth fingers 24 and 25 of the foot. The zone 3F extends into the front zone 3A and the intermediate zone, reaches the rear zone 3C, and partially expands there.

  The outer zone 3F extends from the outer edge 36 over a distance between 20-40% of the full width of the outsole 3.

  The longitudinal zone 3D is separated from the longitudinal zone 3E by a longitudinal bending line 38 provided so as to pass between the toe 21 and the second finger 22, and the longitudinal zone 3E is approximately the third finger of the foot. It is separated from the longitudinal zone 3 </ b> F by a longitudinal bending line 40 provided so as to pass between 23 and the fourth finger 24. The flexibility of the bending lines 38 and 40 is higher than the flexibility of the longitudinal zones 3D, 3E, 3F. As with the transverse zone, this flexibility allows the longitudinal zones to articulate with respect to each other and better transfer force to the ground when playing sports.

  When playing tennis, lateral movement is an important aspect that requires speed and instantaneous power. Therefore, by transmitting force between the foot of the tennis player and the ground, it is possible to ensure the efficiency and speed of turning with deceleration, stop, and restart in different directions. This aspect is also important when the outer zone 3F is stressed by slowing down after the player has run.

  As shown in FIG. 1, the positioning of zones 3A, 3B, 3C, 3D, 3T, 3E, and 3F may not accurately correspond to the positions of various parts of the foot, depending on the different foot configurations. Some toes can span two longitudinal zones in particular, and the longitudinal bending lines 38 and 40 are between the thumb 21 and second finger 22 and the third and fourth fingers 23 and 24. 24 may not pass accurately.

  The midsole 5 has a cushion overlapping the front zone 3A and the intermediate crossing zone 3B. These cushions include an inner cushion 50 that generally overlies the inner zone 3D. Dispersing pressure by the inner cushion 50 when straddling the inside of the foot, for example during a momentary start or jump landing after a serve, with significant force transmission by the big toe 21 for lateral movement Becomes possible, and the stored energy can be returned for better dynamism.

  The midsole 5 further includes a central cushion 52 that generally overlaps the central longitudinal zone 3E. This cushion is stressed during a weight shift stage or ground grip prior to hitting, which requires a stable stance.

  Midsole 5 further includes a third outer cushion 54 that generally overlaps outer zone 3F. For example, the cushion 54 distributes the pressure acting on the outside of the foot when the vehicle is decelerated after the side movement or when the fourth finger 24 and the fifth finger 25 of the foot are shocked during the movement or the direction change. And restart can be guided.

  The central cushion 52 is formed by extending the rear part of the midsole 5 and expanding the member in which the cushions 50 and 54 are incorporated. The cushions 50 and 54 are cushions mounted in cavities of the central cushion 52.

  Alternatively, the central cushion 52 can form an independent element from the rest of the midsole 5 as a fitted cushion of the same type as the cushions 50 and 52. The central cushion 52 can also be constructed of a rigid element, such as a strip of plastic, carbon, or other material, disposed in a housing that extends between the cushions 50 and 54.

  In order to allow a more dynamic movement by the player, the inner cushion 50 and the outer cushion 54 are made of a material having an energy return capability higher than that of the material constituting the central cushion 52. More specifically, the material of the cushions 50 and 54 has an elasticity higher than that of the material of the cushion 52, ie, the ability to quickly return to a shape close to its initial shape after deformation. As a result, a shock is applied to the foot during a lateral movement accompanied by a posture using the thumb 21 or the fourth finger 24 and the fifth finger 25, or in the case of a sudden stop by the fourth and fifth fingers of the foot, for example. Energy is returned to provide relaxation and then increase the speed of the turn, and thus increase the player's overall footwork ability. Since the cushions 50, 52, and 54 coincide with the vertical division of the outsole 3 by the zones 3D, 3E, and 3F, the effect of transmitting force between the player and the ground during the lateral movement is enhanced. It becomes possible.

  As an example, the inner cushion 50 and the outer cushion 54 can be made of a cushioning and elastic material such as synthetic foam or rubber. The central cushion 52 can be constructed of a rigid or semi-rigid synthetic foam.

  The midsole 5 further optionally includes a rear cushion 56 that overlies the zone 3T, which is provided to be located under the heel to provide shock absorption at the heel. In this example, the rear cushion 56 is surrounded by the central cushion 52.

  The bending lines 30, 32, 38, 40 are formed by parallel grooves 42 on the outer surface S 3 of the outsole 3. Ribs 44 extend between the grooves 42. Therefore, in these grooves 42, the thickness 3 of the outsole is reduced, thereby increasing the flexibility.

  In an alternative not shown, the bend line can be formed by a single groove 42.

  These grooves 42 preferably have a depth of between 0.5 and 5 mm, relative to the outer surface S3, when the average thickness of the sole 3 is between 3 and 5 mm. Thus, the groove has a depth corresponding to 10 to 100% of the average thickness of the sole 3.

  According to one alternative of the present invention, not shown, the grooves 42 may cross the entire width of the outsole 3 so that the midsole 5 is visible in the bottom view of the shoe 1.

  The bending lines 30, 32, 38, 40 preferably have a width between 1 and 10 mm.

  As shown in FIG. 1, the bending lines 30, 32, 38, 40 have a bent straight line shape. In general, the bend lines 30, 32, 38, 40 have at least partially a linear shape. In the alternative shown in FIG. 5, the bending lines 30, 32, 38, 40 can also have a curved shape at least partially.

  The transverse bending lines 30 and 32 have a concave shape with the concave side facing backward so as to follow the natural curve of the base of the toe and the front end P1 of the arch.

  The longitudinal bend lines 38 and 40 have a concave shape with the concave side facing the inside of the foot so as to follow the natural curves of the inner and outer edges of the foot.

  The bending lines 30, 32, 38 and 40 are secant lines and form nine subzones.

  The bending lines 30 and 32 extend to the outer edge 36 of the outsole 3 and end before the inner edge 34. In an alternative not shown, the bend lines 30 and 32 can extend to the inner edge 34.

  The bending lines 38 and 40 extend from the center 46 of the outsole 3 provided so as to be higher than the ground to the vicinity of the front end 10. In the illustrated example, the bending line 38 extends to the front end 10, while the bending line 40 ends before the front end 10. In an alternative not shown, the bending line 40 can extend to the front end 10.

  The positions of the longitudinal zones 3A, 3B, 3C and the transverse zones 3D, 3E, 3F and the bending lines 30, 32, 38, 40 are preferably such that some zones of the outsole 3 are more important than others. Can vary.

  For example, a tennis player whose agility is agile and swift will hold more outward and stress zones 3A and 3B forward or zones 3D and 3F towards the side. In such a case, since this player stresses all the zones of the outsole 3, the zones 3A, 3B, 3D, and 3F have a larger area than shoes for players that have poor footwork instantaneous power. become.

  A second type of player with a footwork that is smoother, slower, and more grounded will place more stress on Zone 3B when holding or hitting forward, but against 3A This second type of player places more stress on zones 3E and 3D when turning and blocking. Thus, in a shoe designed for a player with a footwork that is smoother, more grounded and less instantaneous, the zones 3E and 3D will have a larger surface area.

  An optional embodiment of the present invention is shown in FIGS. Also called a sockliner, an insole 7 that is effectively removable from the shoe contacts the foot. The insole 7 has a lower surface 71 that contacts the midsole 5.

  Similar to the outsole 3, the lower surface 71 is divided into a plurality of transverse zones and longitudinal zones separated by a bend line, which are aligned with the zone and the bend line of the outsole 3. The lower surface 71 includes a front zone 71A that overlaps the front zone 3A, an intermediate crossing zone 71B that overlaps the intermediate crossing zone 3B, and a rear zone 71C that overlaps the rear zone 3C. These zones 71A, 71B, 71C are separated from each other by transverse bend lines 711 and 713 that overlap the transverse bend lines 30 and 32, which, like bend lines 30 and 32, are zones 71A, 71B. , Higher than the flexibility of 71C.

  The lower surface 71 includes an inner zone 71D that overlaps the inner zone 3D, a central longitudinal zone 71E that overlaps the central longitudinal zone 3E, and an outer zone 71F that overlaps the outer zone 3F. These zones 71D, 71E, 71F are separated from each other by transverse bend lines 715 and 717 that overlap the transverse bend lines 38 and 40, which, like bend lines 38 and 40, are zones 71D, 71E. , Having a higher flexibility than that of 71F.

  This structure of the insole 7 matches the structure of the outsole 3, thereby improving the overall flexibility of the shoe 1 and making the stance on the ground by various parts of the foot even more effective. It becomes possible.

  Alternatively, the lower surface 71 is formed by the first layer of the insole 7, and the insole 7 has a second layer 73 called an upper layer superimposed on the lower layer 71, which contacts the foot To do. According to an optional aspect not shown, the upper layer 73 has an energy transfer capability that is arranged in accordance with the zones 71A-71F using the same geometry and the same principles as the cushions 50, 52, 54 of the midsole 5. Cushions made of different materials can be included.
