Definitions

  • the present invention relates to an innerboot for sports shoes, particularly for ski boots or for roller skates.
  • a device of this type is all the more interesting because it would allow use of the shoes for an extended period and would also allow to swap or lend ski boots or skates even among users having different foot sizes.
  • FR-A-2 358 117 discloses an innerboot comprising an elastically deformable element.
  • US-5,678,833 discloses an in-line roller skate whose length can be adjusted.
  • Said skate has a rigid supporting frame for a plurality of in-line wheels, a shell which comprises a toe unit and a heel unit, and first means for engagement to said frame which are formed in the heel unit.
  • the heel unit has a sole which is adapted to be slidingly connected, by way of second engagement means, to the base of the toe unit.
  • Said second engagement means comprise third means, such as a screw, for detachably coupling the base of the toe unit to one part of the frame, thus allowing the toe unit to slide with respect to the heel unit in a direction parallel to the longitudinal axis of the skate.
  • third means such as a screw
  • Said conventional skate also has a cuff which is connected to the heel unit by means of a connection device, particularly a pair of studs.
  • the studs are connected to sliding means which are provided on the two lateral walls of the toe unit.
  • the longitudinal movement of the toe unit must be followed by a variation in the length of the innerboot as well.
  • the cited patent discloses an innerboot which has, at the metatarsal region of the foot, an annular band of elastic material which separates the tip of the innerboot and the part that surrounds the heel and the ankle, both of which are made of soft and non-elastic materials.
  • the main drawback of said conventional skate is the fact that it has a limited elongation of the band of elastic material. Such feature would be necessary because a great elongation of the band of elastic material is matched by equally great dimensions thereof.
  • the position of the band of elastic material, arranged completely outside the innerboot, exposes it more to wear and rapid deterioration caused by use and by contact with the outside environment.
  • the aim of the present invention is to solve the noted technical problems, eliminating the drawbacks of the cited prior art by providing an innerboot which allows to use the same innerboot of a ski boot or skate for several different foot sizes, with a consequent financial saving during the manufacture and purchase of the innerboot or skate.
  • An important object is to provide an innerboot which allows to achieve the intended aim while preserving comfort during use when foot size changes.
  • Another important object is to provide an innerboot which achieves the intended aim without requiring inappropriate increase of the space occupied by parts of the innerboot.
  • Another object is to protect the parts of the innerboot that are most subject to wear, in order to extend the useful life of said innerboot.
  • Another object is to provide an innerboot which is structurally simple and has low manufacturing costs.
  • an innerboot for sports shoes comprising at least one first element and one separate second element which are interconnected by a third elastically deformable element, characterized in that said third elastically deformable element is connected on the inner part of said first element and is at least partially concealed by said first element.
  • the reference numeral 1 designates a skate which is constituted by a support 2 for at least two in-line wheels, generally designated by the reference numeral 3.
  • a shell or a heel unit, designated by the reference numeral 4 is associated with the support and is designed to contain an innerboot 5 which can be generically used for sports shoes as well as for skates.
  • the innerboot 5 is composed of a first element, designated by the reference numeral 6, which surrounds the malleolar region and partially surrounds the leg and has a front opening 7 which forms a first flap and a second flap, designated by the reference numerals 8a and 8b respectively.
  • the innerboot 5 is also constituted by a second front element 11 which surrounds the tip of the foot.
  • the front opening 7 can be closed by a tongue 9 which is rigidly coupled to the second element 11, proximate to its lower end, designated by the reference numeral 10.
  • the tongue 9 can be arranged at the tibia and can be secured laterally by said first and second flaps 8a and 8b when said skate 1 or the quarter of a ski boot is closed.
  • the first element and the second element can partially overlap, respectively at a second front edge 12b and at a first rear edge 12a, which are parallel to each other.
  • the first and second elements are connected to one another, at the first and second edges 12a and 12b, by a third element, designated by the reference numeral 13, which is elastically deformable and preferably rectangular.
  • the elastically deformable third element 13 is conveniently arranged inside the first rear element 6; it rests on the bottom 14 of the innerboot and rises along the first and second flaps 8a and 8b.
  • the third element is stitched at the transverse edges 15a and 15b so as to allow the mutual connection of the first and second elements.
  • the elastically deformable third element 13 is thus rigidly coupled, at a first transverse edge 15a, to the inner surface of the first element 6 and, at a second transverse edge 15b, to the first rear edge 12a of the second front element 11.
  • Said coupling is preferably achieved by conventional methods, such as gluing or thermal bonding in addition to stitching.
  • connection region designated by the reference numeral 16 is located directly behind the metatarsal region, although it is possible to provide, according to the requirements, different embodiments with connections in the toe region, in the malleolar region or for example in the region above said heel unit 4.
  • the innerboot is initially arranged for use of a smaller size, since the third elastically deformable element 13 is not stretched and keeps the first rear edge 12a of the second element 11 inside the first rear element 6.
  • the deformation applied to the shell caused for example by the longitudinal sliding of a front toe unit with respect to a heel unit, leads to a consequent deformation of the innerboot 5, so as to allow to accommodate inside it the foot of a larger size.
  • This temporary deformation in any case allows to maintain the connection of the first element and the second element.
  • the at least partial concealment of the third element 13 on the part of the first element 6 protects it against impacts and wear, thus extending the life and functionality of the innerboot.
  • the position, shape and number of the elastically deformable third element may be the most disparate, as shown in Figures 5 and 6, in which there are respectively two elastically deformable third elements 17a and 17b, which affect only the inner lateral surfaces of the second front edge 12b of the first rear element and of the first rear edge 12a of the second front element.
  • the elastically deformable element 13 can be arranged on the outside of the innerboot 5, so that the first rear edge 12a of the second front element 11 lies outside the second front edge 12b of the first rear element 6.
  • the innerboot according to the invention maintains its comfort in use unchanged in all of its arrangements, ensuring considerable duration in terms of useful life.
