Definitions

  • the present invention relates to a securing device, particularly usable for sports footgear, such as for example ski boots.
  • Conventional ski boots are generally constituted by at least one quarter pivoted to a shell by means of a pair of studs.
  • the boots are provided with winders or levers variously arranged at the quarter or quarters and at the shell.
  • the arrangement of winding devices for one or more cables at the rear region of the rear quarter of the boot also makes it uneasy for the skier to actuate the devices.
  • US Patent No. 4,382,342 discloses a ski boot having a half-pulley adapted to wind a cable for a foot presser.
  • the cable adjusting system of this boot is uncomfortable to use in practice.
  • Italian Patent Application No. 21669 A/85 discloses a winder for a ski boot which can be automatically released when the quarter is opened. There is however a possibility of accidental release of the winder while skiing.
  • Italian Patent Application No. 82594 A/88 discloses a winder which is automatically released when the rear quarter is opened. This system, however, leaves the cable unwinded when the quarter is again closed and the winding has to be done manually.
  • the aim of the present invention is to eliminate the problems described above in conventional footgear by providing a device which allows to achieve the optimum recovery of at least one traction element present in an item of footgear, minimizing the space occupied thereby in said item.
  • an important object is to provide a device which is generally easy and comfortable to use for the user and allows to release the traction element in an equally rapid and easy manner.
  • Another important object is to provide a device which allows to keep industrialization for the item of footgear simple.
  • Another important object is to provide a device which leaves unoccupied regions of the item of footgear which are otherwise occupied by conventional securing devices.
  • Not least object is to provide a device which has low manufacturing costs and is reliable and safe in use.
  • a securing device particularly for sports footgear comprising at least one quarter pivoted to a shell by means of a pair of studs, characterized in that said pair of studs comprises a bush which is associated with said at least one quarter and a ring which can move axially with respect to said bush, said device further comprising an axially movable body which is rotatably associated with said ring and has at least one seat for the winding of a traction element and means for temporary engagement with grip means associated respectively with said body and with said ring which can be activated and deactivated by means of the rotation of said at least one quarter, said body interacting with resilient members and being provided with a lever which can be accessed by the user to apply tension to said traction element.
  • the device according to the invention can be applied at sports footgear and, in the particular illustrated embodiment, to a ski boot, generally designated by the reference numeral 1, which is constituted by a shell 2 to which a front quarter 3 and a rear quarter 4 are articulated.
  • the front quarter 3 and the rear quarter 4 are pivotally coupled to the shell 2 at a stud 5 which is constituted by a ring or screw 6, located at the shell 2, and by a bush 7 which can be associated with the front quarter 3.
  • the bush 7 is internally threaded so that it can be screwed at a complementary thread defined on the outside of the ring 6.
  • the ring 6 can move axially with respect to the bush 7, upon a rotation imparted to the bush 7, by means of one or more adapted first radial lugs 8 which are arranged within complementarily shaped first guides 9 formed on the shell 2.
  • the bush 7 also has second radial lugs 10 which are arranged within second guides 11 formed on the rear quarter 4, so as to rigidly couple the bush to the rear quarter 4 during the rotation of the quarter 4.
  • the securing device is also constituted by a body 12 which is rotationally associated at the ring 6 and can slide axially thereto.
  • the body 12 has, in the opposite direction with respect to the front quarter 3, an end 13 which is shaped like a pulley and has an annular seat 14 for the winding of a traction element such as a cable 15.
  • the pulley is therefore arranged inside the shell 2 and has a lateral surface 16 directed toward, and adjacent to, the ring 6.
  • the body 12 is also provided with means for temporary engagement with grip means which are associated with the ring.
  • the grip means are constituted by a first annular set of teeth 17 which is coupled to the temporary engagement means, which are constituted by a second complementary set of teeth 18 formed at the lateral surface 16 of the pulley.
  • the shape of the first set of teeth and of the second complementary set of teeth and the direction of the threads which affect the ring and the bush, are such that a rotation of the rear quarter with respect to the front one in the opening direction leads to a translatory motion of the ring 6 toward the bush 7, so as to mutually disengage the first set of teeth and the second set of teeth, allowing the release of the cable 15.
  • the coupling between the first set of teeth and the second set of teeth is ensured by the presence of a resilient member, such as a spring 19, arranged coaxially to the body 12.
  • the body 12 On the side opposite to the end 13, the body 12 has an arm 20 which protrudes externally with respect to the bush 7 and with which a cover 21 is associated.
  • Cover 21 is provided with an annular ridge 22 which is internally associated with the bush 7.
  • the above described spring 19 thus advantageously abuts between said annular ridge 22 and the ring 6.
  • a longitudinal slot 23 is formed at the arm 20 and acts as seat for a pin 24 for the linkage of a lever 25, which can be accessed by the skier and is provided with a tang 26 which abuts against the underlying bush 7 when the lever is in closed condition.
  • An appropriately rounded protrusion, or ridge, 27 is provided at the region of the cover 21 which is external to the bush 7, and a complementarily shaped indent defined on the facing tang 26 can be arranged at said protrusion.
  • the elastic deformation of the protrusion 27 also allows to disengage said lever from it.
  • the use of the present invention is thus as follows: once the foot has been inserted, the skier moves the front and rear quarters close together, thus keeping the sets of teeth 17 and 18 engaged; then, after gripping the lever 25, he/she applies tension to the cable 15, for example to secure an adapted band 28 which embraces the foot instep region.
  • the skier can release the tension of the cable 15 by simply rotating the rear quarter 4 backward.
  • the thread of the bush 7 in fact forces an axial translatory motion of the ring 6 toward the front quarter 3, because the bush is rigidly associated with the rear quarter 4 during its rotation, by virtue of the presence of the second lugs 10 which are arranged within the second guides 11 of the quarter.
  • the ring is also guided in its axial sliding by the first radial lugs 8 slideable within the first guides 9 defined on the shell 2.
  • the invention has achieved the intended aim and objects, a securing device having been achieved which is first of all applicable at a stud which is already present in the item of footgear, thus leaving free, for said item of footgear, other regions which, in conventional boots, are instead occupied, and also allows to achieve optimum recovery of at least one traction element provided in an item of footgear.
  • the device thus obtained furthermore allows to achieve, upon the opening of the rear quarter, the automatic release of the traction element without having to act on the lever.
  • the lever is arranged in a position which can be easily accessed by the user, who can also perform natural movements in order to wind the cable.
  • the aesthetics of the boot is furthermore improved.
  • the use of the securing device furthermore allows to facilitate industrialization for the boot.
  • the materials and the dimensions of the individual components of the device may also be the most pertinent according to the specific requirements.
