Definitions

  • Sports shoes are currently in use which are usually provided with a sole, with which a rigid or semirigid shell for containing the foot of the user is associated in an upward region.
  • a quarter is typically rotatably associated at the malleolar region and wraps around at least the lower portion of the leg.
  • the sliding interconnection between the two parts i.e., between the heel unit and the toe unit of the shell, is ensured, proximate to the upper metatarsal region, by the presence of an extension that protrudes to the rear from the edge of the toe unit, so as to interact slidingly in a complementarily shaped seat provided proximate to the front edge of the heel unit.
  • the main drawback of this known type of sports shoe consists in that it allows to change the dimensions of the shoe only in a longitudinal direction.
  • an important drawback of these known types of sports shoe relates to the fact that they allow a comfortable fit only to users that have a preset foot size.
  • Another important drawback consists in that the prolonged use of a sports shoe that is excessively tight, for example in the metatarsal region, can cause a slowing in blood circulation, with consequent difficulty for the body to keep the foot warm.
  • the aim of the present invention is therefore to solve the noted problems, eliminating the drawbacks of the cited known art, by providing a sports shoe that allows, as the size varies, an optimum adaptation of the overall volume of the shoe to the foot of the user.
  • an object of the present invention is to provide a sports shoe that allows to ensure maximum comfort of the user regardless of the dimensions of his foot, provided that they are within the size range covered by such shoe.
  • Another object of the present invention is to provide a sports shoe that wraps around the foot so as to allow optimum blood circulation, therefore allowing the user to practice the sport in the best possible physical conditions.
  • Another object of the present invention is to provide a sports shoe that is structurally simple and has low manufacturing costs.
  • a sports shoe that comprises a sole that is rigidly associated with an upper shell that is divided into a heel unit and a separate toe unit, characterized in that it comprises adjusting means for increasing the overall volume of said sports shoe by means of a forward movement of said toe unit.
  • the reference numeral 1 designates a sports shoe, such as for example a ski boot.
  • Sports shoe 1 comprises a sole 2 that is monolithically associated with an upper shell 3, with which a quarter 4 that wraps around the lower part of the leg of the user is rotatably associated approximately at the malleolar region.
  • the shell 3 is divided into a heel unit 5 and a separate toe unit 6, which partially overlap each other approximately at the metatarsal region of the foot.
  • the toe unit 6 constituted by a box-like body that is open at the rear and wraps around the tip of the foot of the user, has a first lower surface 7 in which there is, approximately along its longitudinal central axis, an approximately wedge-shaped slit 8.
  • Slit 8 affects i.e. extends at at least the region where said toe unit 6 and said heel unit 5 overlap, and preferably lies between the rear edge of the first lower surface 7 and the toe region of said surface.
  • the slit 8 forms, on said first lower surface 7, two flat wings 9a and 9b, which are connected each other proximate to the toe region.
  • Two first slots are formed in the two wings 9a and 9b and are obtained along two directions that diverge toward the toe region.
  • Two protrusions 11a and 11b can be arranged in said two slots 10a and 10b and protrude upward from a second lower surface, designated by the reference numeral 12, of said heel unit 5.
  • Said first and second slots 13 and 14 provided along axes that are approximately parallel to the longitudinal central axis of the shoe, approximately mutually overlap in pairs, and are connected in a downward region to two respective holes, generally designated by the reference numeral 15, formed in the sole 2.
  • said holes 15 are formed approximately at right angles in a standardized toe block 16 that is associated with the toe unit 6 in a downward region.
  • the second slots 13 have, in a downward region, a perimetric tang 13a for supporting for example a threaded nut, not shown, which is suitable to interact with a complementarily threaded screw, also not shown, which is arranged coaxially to the hole 15.
  • the nut and the screw whose head abuts against a recess 17 formed in a downward region with respect to the toe block 16, constitute means for temporarily locking the mutual sliding of the heel unit 5 and the toe unit 6.
  • first slots 10a and 10b, and the second and third slots 13 and 14, by interacting respectively with the protrusions 11a and 11b and with the stem of said screws, constitute elements for the mutual engagement and sliding of the toe unit 6 and the heel unit 5.
  • Figures 2 and 3 illustrate the two extreme positions, respectively at the minimum size and at the maximum size, of the shoe 1; such figures show that the divarication of the pair of wings 9a and 9b forces an equal divarication of the elastically deformable sides of the heel unit 5, at least proximate to the region of overlap with the toe unit 6.
  • first slots 10a and 10b together with two wings 9a and 9b, constitute adjusting means for varying the overall volume of the sports shoe by moving forward the toe unit 6 with respect to the heel unit 5.
  • the movement of the protrusions along the first slots entails a divarication or a mutual approach of the two wings of the lower surface of the toe unit, accordingly entailing a variation of the width of the shoe.
  • the user can retighten the screws on the nuts.
  • the invention in fact allows to adjust simultaneously both the length and the width of the shoe, so as to vary its overall volume, ensuring a comfortable condition to the user regardless of the size selected.
  • the sports shoe therefore allows optimum blood circulation, allowing the user to ski always in the best physical conditions.
  • Adjustment occurs simply and rapidly, and it is optionally possible to associate a graduated device for visualizing the adjustment made with the elements for mutual engagement and sliding between the heel unit and the toe unit.
  • Another embodiment provides for two or more slits along the lower surface of the toe unit; as an alternative, one might provide a toe unit that has a lower surface at least partially made of elastically deformable material.
