Definitions

  • the present invention relates to a fastening device particularly for sports shoes, such as for example ski boots.
  • ski boots that have a first flap and a second flap to be fastened at the shell and at the quarter articulated thereto.
  • the flaps are fastened together by levers arranged transversely to the shell and/or the quarter so as to fasten the shoe around the metatarsal region of the foot and/or the lower part of the leg of the user.
  • At least one fastening band that is transversely associated with the quarter, preferably at a region thereof that is arranged at the level of the tibia.
  • Such band usually made of plastics, is provided with a grip means of the type commonly known by the trademark "Velcro", which provides a coupling produced by overlapping.
  • Such band is therefore arranged around the quarter so as to have a first fixed end and a second movable end that can be mutually connected by means of a metallic ring, which is usually made of steel and has an approximately rectangular plan shape.
  • the first fixed end of the band is associated with one side of the metal ring, while the second movable end of the band is inserted at the opposite side thereof.
  • the metallic ring allows to guide the second movable end, which can therefore be pulled by the user toward the region arranged opposite the first fixed end of the band.
  • the guiding of the second end of the band on the ring allows to tension the band as a consequence of the sliding of a portion thereof at the respective side of the metallic ring.
  • the band is locked by overlapping the second movable end on a respective adjacent portion of the band, so as to allow their coupling.
  • a first drawback that is observed in such conventional type of fastening band is the fact that the activation of the bands is very troublesome for the user, because the sliding with respect to the metallic ring is greatly hindered by the friction that occurs between the parts arranged in mutual contact.
  • a further drawback is that the locking of the band is often inaccurate, because unexpected slippages can occur between the band and the metallic ring.
  • a further important drawback is that the band can deteriorate and wear rapidly due to the friction that hinders the sliding of the band with respect to the metallic ring.
  • the aim of the present invention is therefore to solve the drawbacks noted above and therefore solve the described technical problems by providing a fastening device that can be used easily and at the same time allows to achieve precise closure of the shoe around the respective region of the foot or of the lower part of the leg.
  • An object is to provide a fastening device that allows to perform rapidly and safely the guiding and subsequent locking of a band.
  • a further object is to provide a fastening device that is reliable over time and is not subject to deterioration or rapid wear.
  • a further object is to provide a device that is structurally simple and has low manufacturing costs.
  • the reference numeral 1 designates a sports shoe, such as for example a ski boot, which includes a shell 2 to which a quarter 3 is pivoted approximately at the malleolar region.
  • the shell 2 and the quarter 3 have a first flap 4 and a second flap, not shown, which can be mutually connected for example by partial overlap in the metatarsal and instep region.
  • the fastening of the first flap 4 and of the second flap around the foot and the lower part of the leg of the user is performed by activating levers, of a per se known type, each designated by the reference numeral 5, and a fastening device according to the invention, generally designated by the reference numeral 6.
  • the device includes a band 7, made for example of plastics, which has a first male layer at one surface and a second female layer at the opposite surface, both of the type commonly known by the trademark "Velcro", so that they can be mutually coupled by overlapping.
  • a band 7 made for example of plastics, which has a first male layer at one surface and a second female layer at the opposite surface, both of the type commonly known by the trademark "Velcro", so that they can be mutually coupled by overlapping.
  • the band 7 is arranged transversely to the quarter 3, so as to surround the quarter, for example at the region of the tibia, and has a first fixed end, designated by the reference numeral 8, and a second movable end, designated by the reference numeral 9.
  • the first fixed end 8 of the band 7 is rigidly coupled to the first flap 5 and at the same time is associated with a ring 10 which is preferably metallic and is allowed to cooperate with the second movable end 9, so as to allow its guiding.
  • the ring 10 has a preferably rectangular shape and is constituted by a pair of spacer shoulders or linkages, generally designated by the reference numeral 11, that are mutually parallel.
  • a first pivot 12 and a second pivot 13 are associated transversely, for example by riveting with the ends of the shoulders 11.
  • the pivots are arranged at a preset distance from each other and approximately at right angles to the spacer shoulders or linkages 11.
  • the first fixed end 8 of the band 7 is associated with the first pivot 12, and a first means for limiting the friction between the band 7 and the ring 10 is rotatably associated with the second pivot 13; the means is preferably constituted by a roller 14, which is arranged coaxially with respect to the second pivot 13 so as to be freely pivoted with respect to the pivot.
  • the roller 14 has a circular annular transverse cross-section and an approximately I-shaped longitudinal cross-section.
  • the roller 14 is provided with a second means, suitable to increase the friction with the band 7, which is preferably constituted by a plurality of protrusions 15 which protrude radially and longitudinally with respect to the outer surface 16 of the roller 14.
  • Figures 1 to 3 show how it is possible to insert manually the second movable end 9 through the gap between the first pivot 12 and the roller 14, so as to allow, by pulling manually the second end 9, the subsequent guiding of the end toward the region directed away from the first fixed end 8.
  • the rotation of the roller 14 about the second pivot 13 occurs easily, since the friction produced between the parts arranged instantaneously in contact is very small, for example by applying lubricants or by using suitable materials.
  • Respective first annular ridges designated by the reference numeral 17, protrude radially at the ends of the outer surface 16 of the roller 14, and contain and guide the band 7 during its sliding with respect to the second pivot 13.
  • Second annular ridges 18 protrude axially at the ends of the outer surface 16 of the roller 14, preferably in a region adjacent to the lateral surface of the second pivot 13, and are arranged approximately at right angles to the first ridges 17.
  • the function of the second annular ridges 18 is to reduce the friction of the roller 14 also in relation to the facing surfaces of the spacer shoulders or linkages 11.
  • the roller also allows to avoid or at least reduce drastically the wear of the band, both by way of the drastic reduction of the friction that occurs between the band and the ring and because the diametrical dimension of the roller gives the band a larger contact surface.
