Definitions

  • the present invention relates to a last for manufacturing a various kind of the shoe such as a conventional shoe, leisure/sport shoe that enables to fit the human foot shape.
  • the last for manufacturing a shoe has a foot shape, and is made of metal, wood or synthetic resins.
  • the process thereof is comprising attaching the uppers of the shoe in the bottom of the shoe sole in the state of the exterior of the last being covered with uppers to form shoe, and then dividing the last from a shoe.
  • the corresponding space to the last is so formed inside the shoe that a shoe provides a space to fit for the foot.
  • the conventional last is manufactured to cover overall rough shape in a simple way without considering concrete bend area such as toes or ankle bone. Thus, it causes inconvenience when it is fitted.
  • a foot consists of 23 pairs of bones, muscles, joints, ligaments, nerves and blood vessels. It is divided into the forefoot, the midfoot and the rearfoot.
  • the forefoot consists of 5 metatarsal bonds including toes
  • the midfoot has arch type
  • the rearfoot consists of calcaneus.
  • the first to third metatarsal bonds corresponding to the big toe and the third toe are linked to the ankle, and the fourth to the fifth metatarsal bonds are linked to the to the shinbone thorough the calcaneus bond.
  • Such a metatarsal bond constructs lateral arch to support ligament and nerve, and column arch with plantar fascia.
  • the interaction between muscles and bones of arches makes the body stable, absorbs shocks and disperses the body weight.
  • the present inventor made a study for an invention of manufacturing a last, based on the anatomical and bionics resources, and as a result, found that if the last is prepared with the same shape of the foot, it is possible to manufacture a shoe to have a good fitting feeling and convenience.
  • the present invention is accomplished on the basis of the above finding.
  • shoe sole should stick to the sole to give free movement inside a shoe in order to enhance fitting except for shoes such as professional inline skate or cycle shoes where a foot is fixed inside the shoe. And, every shoe should be manufactured with same material in order to achieve such aim.
  • the portions like a sole bone or the metatarsal bone shape, and the bone between toes and metatarsal are perfectly fixed in the shoe on wearing, giving a feeling as if it moves in a barefoot. And it prevents any foot diseases for those walking or moving for a long periods of time.
  • the present inventor studies the pressure of foot and shape change in bionics resources, and reflected the said study.
  • the present invention is characterized in its construction of the last (10) embodying human body shape as it stands. Specifically, it selectively forms the forefoot (21) of last for manufacturing a shoe, the first protruding portion (11) in a round form at the front and upper direction corresponding to a big toe shape, convex-concave portion (12) corresponding to each protruding shapes of the second or fifth toe of the forefoot of the above last, the midfoot of the above last (22), the second protruding portion corresponding protruding bones from the midfoot internal portion to external portion, first concave portion (14) corresponding to the concave portion in arch type on the floor of the midfoot in the sole of the above last, second concave portion (16) corresponding concave on the border between toe and the midfoot in a lateral direction in the forefoot and the midfoot of the above last, third concave portion (15) corresponding
  • Fig. 1 is a perspective view of the last according to an embodiment of the present invention.
  • Fig. 2 is a perspective view of the forefoot last according to an embodiment of the present invention.
  • Fig. 3 is a plan view of the last according to an embodiment of the present invention.
  • Fig. 4 is a side view of the last according to an embodiment of the present invention (big toe).
  • Fig. 5 is a bottom view of last according to an embodiment of the present invention.
  • Fig. 6 is a bottom view of the forefoot of last according to an embodiment of the present invention.
  • the last (10) of the present invention is manufactured in the same shape with a body foot especially, toes and sole. It can be manufactured with wood, synthetic resin or metal and other material can be available.
  • the above last (10) consists of the forefoot (21), the midfoot (22) and the rearfoot (23).
  • the forefoot (21) is to form 5 metatarsal bonds linked to toe ones
  • the midfoot (22) is to form the middle portion with arch type
  • the rearfoot (23) is to form calcaneus.
  • one side of the forefoot (21) of the above last (10) has first protruding portion (11) corresponding to big toe shape, and the first protruding (11) portion is protruding in a round form to the front and upper direction as in Fig. 3 and Fig. 4 .
  • the forefoot (21) of the above last (10) creates corresponding protruding shapes of second or fifth toe, forming round type convex-concave portion (12) in a zigzags, and the above convex-concave portion (12) is linked to the above first protruding portion (11). More specifically, the above convex-concave portion (12) is extended to the roundly protruding portion toward first protruding portion (11) and linked in a round zigzag type.
  • the internal area of the midfoot (22) of the above last (10) has protruding arch type second protruding portion (13) outwards, and the second protruding portion (13) corresponds to the ball of foot, the protruding bone from inside of the midfoot toward outside.
  • the internal area of the midfoot (22) of the above last (10) has the first concave portion (14) upwardly corresponding form to the arch type concave from the sole of the midfoot.
  • top of a foot of the above last (10) has the third rounded protruding portion (17) upwardly corresponding to the upwardly protruding bones in a arch type of the top of a foot.
  • the sole of body foot forms several types concaves as well as first concave portion (14) between the forefoot (toes) and the midfoot. Considering the purpose of the present invention, it is desirable to form a concave corresponding to that of sole in the base of the last.
  • the borderline between the forefoot (21) and the midfoot (22) of the above last (10), it forms lateral second concave portion (16) between toes and the midfoot.
  • the above second concave portion (16) embodies concave against sole in the fifth toes. It shows concave in a lateral direction from the foot ( Fig. 4 or 6 ).
  • the metatarsal bonds consist of 5 linking between the acropodium and tarsometatarsal joint.
  • First metatarsal is linked to the big toe bone
  • the fifth metatarsal is linked to the fifth toe bone.
  • the above third concave portion (15) is corresponding to the concave.
