Definitions

  • the present invention relates to a “hybrid” fastening assembly adapted to be associated with the upper or the shell of sports footwear such as for example ski or snowboard boots, skates, hiking boots or cycling shoes, provided with a pair of flaps which can be overlapped or approached to attain the releasable and adjustable fastening thereof around the foot of the user.
  • a fastening assembly is characterised in that it has a reel-based tightening device and a lever fastening device operating synergistically.
  • Such reel-based fastening devices comprise a hollow containment casing which can be constrained to a first flap of the footwear, wherein there is housed a winding mechanism provided with a reel with which an end of traction cable is associated.
  • the winding mechanism is operatively connected to a knob through which the user can rotatably actuate the reel, to wind/unwind the cable around the reel.
  • a hollow intermediate portion is associated with a second flap of the footwear, so that by moving the reel-based tightening device there can be obtained the progressive moving closer or further away of the flaps, and therefore the desired fastening action.
  • Any guide members between which a respective intermediate portion of the cable is passed through may be applied on a flap or on both flaps to allow a more even fastening of the footwear.
  • the reel-based fastening devices are particularly popular among users given that they allow to continuously recover the traction cable, therefore enabling to gradually change and very precisely adjust the fastening of the footwear until the desired degree is reached.
  • reel-based devices require very little effort to achieve the fastening of the footwear and they are rather intuitive to use because they can be actuated through a single control knob.
  • the main task of the subject matter of the present invention is to provide a fastening assembly adapted to be applied to a sports footwear provided with a pair of flaps to be moved mutually towards/away, which is capable of exploiting the advantages of a reel-based tightening device, simultaneously overcoming the disadvantages related thereto and shown above.
  • an object of the present invention to provide a fastening assembly that allows a micrometric and continuous adjustment of the degree of fastening, while simultaneously having the possibility of quickly releasing the closing tension of the footwear, while maintaining the “memory” of the degree of fastening achieved previously, so as to allow the user to return the footwear to the desired fastening condition in a rapid and immediate fashion.
  • Another object of the present invention to provide a fastening assembly capable of evening the fastening condition of the two flaps of the footwear to which it is associated and making the fastening process gradual and comfortable.
  • a further object of the present invention is to provide a fastening assembly that is durable and functional, and that is easy to use.
  • an object of the present invention is to provide a fastening assembly that can be obtained by using means and components that are readily available, and which can be obtained using usual and known plants, machines and equipment.

  • the winding mechanism is operatively connected to a knob 22, advantageously mounted on the hollow containment casing 21 , through which the user can rotatably actuate the reel, with a determined transmission ratio, in a first direction of rotation, or winding direction, so that said cable 10 is wound around the reel, therefore obtaining a progressive approaching of the flaps L1 , L2 and therefore the desired fastening action thereof, or in the opposite direction, or unwinding direction, to obtain the unwinding of the cable 10 from the reel and allow the moving away of the two flaps L1 , L2.
  • Said winding mechanism further comprises suitable and known retaining means adapted to retain the progressive position of the reel, so as to maintain the tensioning condition of the cable 10 achieved progressively, both in the winding direction and in the unwinding direction, therefore allowing to carry out a micrometric and continuous adjustment of the closure of the flaps L1 , L2 of the footwear 100, further providing end stops for the rotary movement of the reel, both in the winding direction and in the unwinding direction.
  • said retaining means may also release the reel, allowing it to rotate freely in the unwinding direction so as to allow the quick release of the cable 10.
  • the transmission ratio of the winding mechanism may for example be of the type 1 :1.
  • the degree of tensioning of the cable 10 also increases directly proportionally to the increase of the effort that the user is to exert on the knob 22 to obtain the desired fastening effect.
  • An advantage of such characteristic lies in the fact that the cable 10 can therefore be wound around the reel within a short time and this is particularly advantageous in a condition in which the cable 10 is scarcely tensioned or not-tensioned and therefore it is necessary to recover the stroke thereof quickly so as to fasten the footwear.
  • the transmission ratio of the winding mechanism may be of the type 3:1 .
  • the effort that the user is to exert on the knob 22 to obtain the desired fastening effect does not increase by the same amount as the tension of the cable 10 increases but it is reduced by three times with respect to the tension of the cable 10.
  • the winding speed of the cable 10 on the reel is rather slow, although less tiring to the user, allowing a fine adjustment of the degree of fastening.
  • the winding mechanism may advantageously be provided with revolution counter device, which allows to identify the number of revolutions that the user has carried out to reach the tension of the cable 10 and therefore quickly recall the degree of fastening set previously.
