Definitions

  • the present invention relates to a component for footwear and footwear that comprises it.
  • the present invention relates to a component apt for realizing an insole or a midsole and designed or intended to be integrated into a sole for footwear to facilitate the user's movement during walking or running or jumping.
  • the present invention is in the field of footwear production.
  • a dampening insole having a curved portion that defines, in use, a concave portion towards the ground, which extends from the metatarsophalangeal joint to the heel.
  • a sole that comprises this component for footwear is shaped so as to introduce a concavity on the side of the sole, when at rest, so that when the user places the foot on the ground and applies weight on it, the component for footwear assumes a flat configuration, storing elastic energy that is released when the foot is lifted again.
  • this sole and the component for footwear which comprises it permit to facilitate walking, reducing the energy required by the user.
  • this form of sole implies a greater chance of stumbling and thus reduces the safety of use of such footwear with respect to the conventional footwear.
  • the underlying problem of the present invention is to facilitate walking or running or jumping without compromising the comfort and safety of use.
  • the main task of the present invention is to provide a component for footwear and footwear that comprises it that poses a solution to this problem by solving the aforementioned disadvantages of the footwear described above.
  • Another object of the present invention is to provide a component for footwear and a footwear comprising it that is structurally simple, easy to implement and easy to use in the manufacture of footwear.
  • Yet another object of the invention is to propose a component for footwear and footwear that comprises it that permits, during use, to maintain a more natural posture of the feet with respect to other known solutions.
  • a component for footwear preferably apt to constitute an insole, a midsole or similar element, comprising an operating portion 11 engageable by the forefoot of a user, which has an upper face 12 apt to receive the resting of the user's forefoot and a lower face 13 apt to be covered by a sole 14.
  • the operating portion 11 develops along a longitudinal direction A which, in use, is parallel to the anteroposterior direction of the user's foot.
  • the component for footwear 10, according to the present invention has a particular peculiarity in that, along this longitudinal direction A, the operating portion 11 develops along a trajectory B which is curved such that the lower face 13 is concave and the upper face 12 is convex.
  • the operating portion 11 is made of an elastically deformable material such that the curvature of the operating portion 11 is invertible to store elastic potential energy as a result of the stress exerted by the user's forefoot during walking, running or jumping.
  • forefoot it is meant the portion of the foot that extends longitudinally from the anterior extremity of the toe tip to the metatarsophalangeal joint.
  • the material with which the operating portion is made is preferably a composite material that advantageously, at least one layer of carbon fibers preferably unidirectional with direction parallel to the principal direction and at least one layer of aramid fibers, advantageously in the form of a fabric, superimposed on the layer of Carbon fibers.
  • the component of footwear 10 or at least its operating portion 11 has a substantially constant thickness and preferably comprised between 1 and 3 mm.
  • the component of footwear 10 is entirely constituted by the operating portion 11, in which case the operating portion is shaped to define a support for the entire sole of the user that can be rested directly or, preferably indirectly, being the operative portion 11 covered for example by a lining or by an insole.
  • insoles which are not integrally constitute of the operating portion 11 but comprise them together with an auxiliary part which may be in material different with respect to that of the operating portion realized and which will be complementary to the latter to define a support for the entire sole of the user's foot.
  • a component for footwear 10 has a curvature towards the support zone of the user's forefoot so that, when the user rests it on the ground, the component for footwear deforms by assuming a substantially flat development.
  • the component for footwear deforms due to the action of the footwear which is advantageously structured to maintain the component of footwear attached to the sole of the user's foot.
  • the operating portion assumes, during the movement above mentioned, a curvature opposite to the initial in correspondence of the metatarsophalangeal joint.
  • the elastic reaction of the component of footwear tends to re-assume its initial configuration and, pivoting on its front edge, helping the foot of the user in lifting movement and advancing contributing thus to the work spent by the user to walk.
  • the operating portion 11 is configured along the longitudinal direction A so as to extend throughout the length of the sole of the user's foot to which the component of footwear 10 is intended.
  • the operating portion 11 extends advantageously along the trajectory B, between a front edge 14 and a rear edge 15 and is provided solely on a side of plane X tangent to the lower face 13 in correspondence to the edges 14,15.
  • the maximum distance Dm of the lower face 13 from said plane preferably has a value comprised between 2.5% and 7.5% of the extension of the component of footwear 10 along the longitudinal direction A.
  • the lower face 13 assumes said maximum distance at a distance Db from the front edge 14, considered along the longitudinal direction A, having a value between 30% and 40% of said linear extension, and preferably equal to 35% of the latter.
  • the component of footwear 10 increases the comfort of use of a footwear that comprises it, if along the longitudinal direction A is curved in correspondence to the edges 14, 15 so as to give the upper face 12 locally concave to adapt to the anterior extremity of the toes of the feet and at the posterior extremity of the heel respectively.
  • the upper face 12, cross-sectional view according to a plane perpendicular to the trajectory B, which in figure 2 can be represented with the plane parallel to the plane of section III-III, is concave for at least a first portion C of trajectory B where said first portion C corresponds to a first zone of the operating portion 11 which is apt to receive at least the user's phalanges.
  • the operating portion 11 has a stiffening zone which is positioned in such a way that, in use, it is engaged by a part of the foot sole adjacent to the metatarsophalangeal joint, towards the heel.
  • This stiffening zone 16 has a curvature greater of the curvature of the operating portion along the longitudinal direction, in a way such that in correspondence to this stiffening zone 16, the lower face has a concavity greater and the upper face has a greater convexity.
  • the upper face 12 view according to said section has a convex central part 17 which is placed between two concave lateral parts 17a and 17b.
  • This second portion D preferably extends in a second zone of the operating portion 11 which is apt to support a part of the sole of the user's foot adjacent to the metatarsophalangeal joint towards the heel.
  • the material or materials for making the component of footwear 10 or at least the operating portion 11 will be selected so as to exhibit substantially purely elastic behavior in view of the stresses and flexural deformations that the component of footwear 10 undergoes during walking depending on the type of user and the use to which the footwear is intended which comprises this component for footwear 10.
  • a component for footwear made according to the present invention has proven that particular efficiency in assistance to walking, running or jumping is achieved by making the component for footwear 10 or at least it's operating portion 11 in a material having a module Of elasticity substantially comprises between 83,000 MPa and 85,000 MPa and preferably substantially equal to 84,000 MPa.
  • the tensile breaking load for an optimum material for making the operating portion 11 is advantageously equal to or greater than 840 N / mm2.
  • This elasticity and breaking load module can be determined by means of an ISO 527 tensile test with AMSLER test machine with full-scale 100 kN and a LONOS TEST data acquisition system.
  • a footwear comprising a component for footwear 10 which is configured as described above and a sole 200 attached to the lower face 13 of the component for footwear 10 and configured in a way not to counteract the flexion of the component for footwear 10 during use, for example by providing a dip 210.
