Definitions

  • the present invention relates to a footwear pertaining to -athletic shoes. More particularly, the invention is directed to a footwear suited for enhancing and improving an athletic ability and body function of human.
  • a muscle of a human leg portion is one of the largest muscles in the human body. It is reported that only half of such human leg muscle is used for most of daily activities. In particular, in the case of a person having few opportunities for exercises due to deskwork or the like, a muscle in the inside of his or her thigh portion or a muscle in his or her buttocks portion is prone to wane and it is difficult to strengthen those particular muscle portions. Solution to such problem is attainable by providing an effective way to enhance or stretch the muscles, sufficient to improve the body function and athletic ability.
  • the under-listed prior art literature 1 discloses a footwear for physical exercise purpose, which has a particular sole of such a structure that a forward side (on the toe side) thereof is greater in height than a backward side (on the heel side).
  • the insole of shoe is so formed to provide a downwardly sloped surface which becomes gradually lower as it proceeds from the forward portion thereof to the backward portion thereof.
  • This arrangement of shoes gives a user walking therewith such an experience as if he or she walked on an uphill road generally identical in inclination angle to the sloped insole, with his or her heel portions being kept in close proximity to a ground surface, thereby providing a proper exercise effect to the user.
  • the prior art literature 1 Japanese Laid-Open Patent Publication No. Hei 9-164002
  • this sort of footwear inherently includes the high toe region and the low heel region, which in fact makes it difficult for a user to walk in a normal way. That is, basically sated, for the user to walk in a normal way, his or her weight must be shifted in the following orders: the heel, the base of toe, and the tiptoe.
  • a footwear in accordance with the present invention is characterized by comprising: a first sloped surface defined inside of the footwear, the first sloped surface being inclined such that one side thereof on which a base of toe of human foot is to be positioned is higher than another side thereof near to a heel side of the footwear; a second sloped surface defined in a sole of the footwear, the second sloped surface extending from an area of said sole where the base of toe of human foot is to be positioned, in a direction toward a toe side of the footwear; and a third sloped surface defined inside of the footwear, the third sloped surface being inclined such that one side thereof on which a big toe of human foot is to be positioned is lower than another side thereof on which a small toe of human foot is to be positioned.
  • the footwear is characterized in that at least one functional equipment is provided to the sole of the footwear.
  • Another aspect of the present invention is characterized by comprising: a first sloped surface defined inside of the footwear, the first sloped surface being inclined such that one side thereof on which a base of toe of human foot is to be positioned is higher than another side thereof near to a heel side of the footwear; a second sloped surface defined in a sole of the footwear, the second sloped surface extending from an area of the sole on which the base of toe of human foot is to be positioned, in a direction toward a toe side of the footwear; and at least one functional equipment provided to the sole of the footwear.
  • Still another aspect of the present invention is characterized in that at least one functional equipment is provided to a sole of the footwear, and that the functional equipment is one selected from the group consisting of: rotatable circular plates; rotatable balls; springs; edges; and slidable plates.
  • a footwear comprising: a first sloped surface defined inside of the footwear, the first sloped surface being inclined such that one side thereof on which a base of toe of human foot is to be positioned is higher than another side thereof near to a heel side of the footwear; and a second sloped surface defined in a sole of the footwear, the second sloped surface extending from an area of the sole where the base of toe of human foot is to be positioned, in a direction toward a toe side of the footwear.
  • a third sloped surface may be defined inside of the footwear, the third sloped surface being inclined such that one side thereof on which a big toe of human foot is to be positioned is lower than another side thereof on which a small toe of human foot is to be positioned.
  • a functional equipment may be releasably connected with a potion of the sole of footwear at which the base of toe of human foot is to be positioned.
  • Such arrangement of footwear is advantageous in that a user can keep his or her appropriate posture and enhance his or her sports ability, and that it is possible to make any effective use of the footwear to not only prevent development of various symptoms due to a lopsided weight in the foot portions, but also provide symptomatic improvement in that respect.
  • the functional equipment is provided to the second sloped surface, the user can simply shift his or her weight forwards in a direction from the heel side to the toe side, to thereby permit use of the functional equipment, or conversely, in a direction reverse to such forward weight shift, the user can shift his or her weight so as to avoid use of the functional equipment.
  • the use of such functional equipment enables the user to enhance and stretch muscles in his or her leg portions as well as muscles in his or her other body portions.
  • FIG. 1 is a diagram illustrating a structure of Embodiment 1 of the present invention.
  • Fig. 1(A) is a side elevational view showing a structure of the present embodiment.
  • Fig. 1(B) is a front view of the present embodiment as viewed in the direction of arrow F1 in the Fig. 1(A).
  • Figs. 2 and 3 are diagrams illustrative of how the present embodiment is used.
  • the illustrated shoe 10 includes a shoe sole 12 having a thickened region defined at a point near to a side forwardly-of the shoe in relation to a center of sole of a-user' foot; namely, an area of the insole where a base of toe of a user's foot is to be positioned, wherein the term "base of toe” refers to a joint between the toe and instep of user's foot.
  • base of toe refers to a joint between the toe and instep of user's foot.
  • the insole of shoe 10, on which the sole of foot of the user 50 is to be contacted is sloped with respect to a ground plane 40 as indicated by the line LA.
  • the ground plane 40 is shown as extending horizontally with a view to facilitating the ease of understanding about the present embodiment.
  • the insole of the shoe 10 is sloped with respect to the ground plane 40, such that one area thereof on which the user's big toe is to be positioned is lower than another area thereof on which the user's little toe is to be positioned, as indicated by the line LB.
  • the shoe sole 12 has a sloped surface 18 which is upturned or extends upwards from one side of the shoe sole on which the afore-said base of toe of user's foot is to be positioned, in a direction toward a toe side 14 where a distal end part of the user's foot is to be positioned.
  • the engagement member 30 may comprise a flat plate 30A of square shape and a male engagement shaft 30B adapted for allowing the functional equipment to be releasably engaged therewith, the male engagement shaft 30B erecting from a center of the flat plate 30A. That particular male engagement shaft 30B is exposed in a recessed portion 12A formed in the shoe sole 12.
  • the engagement member 30 is fixed in the shoe sole 12 such that an axis of the engagement shaft 30B thereof is oriented to and aligned with the normal to an outer surface of the shoe sole. That is, the arrangement of the engagement members 30 in the shoe sole 12 is such that, at every local area of the shoe sole 12 which corresponds to each engagement member 30 and is to contact the ground plane 40, any male engagement shaft 30B corresponding thereto is to be substantially perpendicular to the ground plane 40.
  • the male engagement shaft 30B disposed at that particular portion of shoe is substantially perpendicular to the ground plane 40.
  • a rotating adapter 20 may be provided as one exemplary part of the foregoing functional equipment.
  • Such rotating adapter comprises a female engagement shaft 20C and a circular base plate 20A adapted for contact on the ground plane 40, wherein the circular base plate 20A is rotatably connected with the female engagement shaft 20C via a bearing mechanism 20B.
  • the female engagement shaft 20C has an engagement hole 20D formed therein.
  • This rotating adapter 20 may be releasably and rotatably engaged with the engagement member 30 by inserting the male engagement shaft 30B disposed in the shoe sole 12 into the engagement hole 20D.
  • the user can stand on one foot and rotate or spin his or her body, wherein, normally, such rotating or spinning action could hardly be done without some optimum condition including the case where the user stands on the ice of a low degree of ⁇ (the ⁇ is a friction resistance) or the case where the user stands on a slippery polished floor.
  • the user can stand on both feet and take an exercise like twist dance. Accordingly, it is possible for the user to train a sense of balance by taking the spinning exercise stated above. Or, alternatively, by taking the twist-dance exercise stated above, the user can easily do a "twisting" action which is not done so much in his or her daily activities.
  • an oblique abdominal muscle In a normal twisting action, an oblique abdominal muscle is mainly used. But, a user wearing a pair of the shoes 10 of the present embodiment can efficiently stimulate his or her oblique abdominal muscles that have not been used for years due to aging or insufficient exercise, whereby, for example, the following effects can be expected: preventing and relieving a low back pain; enhancing muscles in the waist portion; reducing fat in the waist portion; and relieving constipation.
  • the user may shift his or her weight toward the toe side 14 of the shoe, and on the other hand, if it is unnecessary to use the rotating adapter 20, the user may shift his or her weight toward the heel side 16 of the shoe, or may remove the rotating adapter 20 from the shoe.
  • a user removes the rotating adapter 20 from the shoe 10 of the present embodiment, and wears such shoe 10 without the rotating adapter 20 to walk or take a physical exercise.
  • a normal use state of the shoe wherein a whole of the shoe is placed and contacted on the ground plane
  • a stepping state of the shoe wherein the user wearing the shoe is about to step on the ground plane for a certain action may be depicted in Fig. 2(B).
  • the thus-attained inward weight is maintained, which makes it possible to prevent and remedy bow-legs, knock-knees and a combination of bow-legs and knock-knees.
  • the user can walk, with his or her calves being stretched to a certain degree, in which case, a limitation is given to a range in which the muscles of the calves can act and move, with the result that, to compensate for such limited movement of calf muscles, a reactive movement is caused in muscles in a backward region of user's thigh portion (i.e.
  • the user wearing the shoe may wish to stop and stand on the toes.
  • the user stands only on a portion of the shoe where the base of toe of his or her foot is positioned, or more clearly stated, the user stands on a local point corresponding to the sloped surface 18 of shoe sole 12 which faces downwards. Under such state, the user can either stand upright or effect a footwork training with respect to the line extended between the thenar eminence and the hypothenar eminence.
  • the insole of the shoe 10 is provided with: a slope inclined such that one area of the insole on which the base of toe of user's foot is to be positioned is higher than another area of the insole near to the heel side 16; a slope inclined such that one area of the insole on which a big toe of user's foot is to be positioned is lower than another area of the insole on which a small toe of user's foot is to be positioned; and a sloped surface 18 which is turned up from the foregoing insole area where the base of toe of user's foot is to be positioned, in a direction toward the toe side 14.
  • the rotating adapter 20 is releasably connected with a point of the shoe sole 12 which corresponds to such insole area where the base of toe of user's foot is to be positioned. Accordingly, the following effects are attainable:
  • the rotating adapter 20 is used as one mode of the functional equipment, but, in place thereof, for example, one of the following items may be used as an alternative mode of the functional equipment: a spike (or clamber), a ball, a roller, a spring, and an edge.
  • Fig. 4 illustrates some exemplary modes of such alternative functional equipments.
  • one alternative mode of the functional equipment is shown as comprising a generally U-shaped spring 100 and an engagement shaft 102 provided to that spring.
  • an engagement shaft 112 is provided to a spiral spring 110, thereby forming an alternative mode of the functional equipment.
  • two detent plates 114 and 116 are provided to the respective two sides of the spring 110, and the engagement shaft 112 is connected with the detent plate 116.
  • a ball (a spherical element) 120 is rotatably secured in a joint 122, thereby forming an alternative mode of the functional equipment.
  • an engagement shaft 124 is provided to a top of the joint 122.
  • Fig. 4(D) shows an example wherein two engagement shafts 132 and 134 are provided to a ski 130 for grass skiing, thereby forming an alternative mode of the functional equipment.
  • a pair of the engagement members 30 should necessarily be provided in the shoe sole 12 in order to permit engagement thereof with the respective two engagement shafts 132 and 134.
  • the two engagement shafts 132 and 134 may be connected with an edge for skate, instead of with the ski 130.

  • bolts and nuts may be arranged appropriately for connection of the functional equipment with the engagement member 30.
  • a magnet be used for that purpose. In particular, if the magnet is used as an alternative to the engagement member-30; a magnetism therefrom will act on a user's foot, so that some advantageous effects to the foot can be expected.
  • the footwear disclosed in the present invention is indeed suited for enhancing physical capabilities of user in association with: a sport of the type requiring abrupt dash and stop, which includes tennis, baseball, basketball and volleyball; a sport of the type requiring instantaneous force, which includes a running long jump and a running high jump; and a sport of the type requiring a training of user's heel portion to exert his or her ability, such as golf, judo, and weightlifting.
  • the footwear of the present invention is not limited to the sports, but may be used as a usual footwear. Also, the footwear of the present invention may be used for dance or skate.
  • a footwear comprising: a first sloped surface defined inside of the footwear, the first sloped surface being inclined such that one side thereof on which a base of toe of user's foot is to be positioned is higher than another side thereof near to a heel side of the footwear; and a second sloped surface defined in a sole of the footwear, the second sloped surface extending from an area of the sole where the base of toe of user's foot is to be positioned, in a direction toward a toe side of the footwear.
  • a third sloped surface may be defined inside of the footwear, the third sloped surface being inclined such that one area of the insole, on which a big toe of user's foot is to be positioned is lower than another area of the insole on which a small toe of user's foot is to be positioned.
  • a functional equipment stated above may be releasably connected with a portion of the sole of footwear at which the base of toe of user's-foot is to be positioned.
  • Such arrangement of footwear is advantageous in that a user can keep his or her appropriate posture, and that the user can simply shift his or her weight forwards in a direction from the heel side to the toe side, to thereby permit use of the functional equipment, or the user can shift his or her weight in a direction reverse to such forward weight shift so as to avoid use of the functional equipment. Accordingly, it is possible to make the footwear of the present invention adaptable for use in various kinds of sports.
  • the sole of the footwear has the sloped surface, by virtue of which, it is possible to eliminate the need for increasing the thickness of the footwear sole in the case where a functional member is embedded in that particular footwear sole. Hence, the thickness of the footwear sole is not increased, irrespective of the functional member being embedded therein, which effectively attains a good aesthetic appearance of the footwear. Accordingly, the footwear of the present invention deserves a design-oriented footwear.
