Definitions

  • This invention relates to an adjusting and fastening device particularly for ski boots.
  • a lever arrangement which, in its more general embodiment, includes a part articulated to one of the flaps to be secured together, to which part a ring or hook arrangement is connected for engagement with a mating part attached to the other of the flaps to be secured together, a rotation movement of the lever being effective to bring together and tighten such flaps.
  • This form of adjustment has, first of all, the disadvantage that it must be performed with the lever in the open, i.e. unlatched, position, and moreover, cannot provide fine adjustment capabilities because, in order not to have the hook or ring located at the wrong position, it is generally required that a 360 0 rotation be completed, which results in a one pitch length translation of the threads utilized.
  • a further object of this invention is to provide an adjustment device which, owing to its peculiar design, can give full assurance of reliable and safe operation, while affording a high degree of versatility of the device.
  • a not unimportant object of the invention is to provide such a device, which is of simple construction and can be readily manufactured from widely available elements and materials.
  • an adjusting and fastening device particularly for ski boots comprising a body adapted for association with one of the ski boot flaps to be secured together and being characterized in that it comprises a first actuating element carried rotatably on said body and being accessible from outside of said body, said first actuating element interacting with a rotary to translatory motion conversion unit associated with a link element connected to engagement means interacting with the other of said ski boot flaps to be secured together.
  • the adjusting and fastening device particularly for ski boots comprises a body, indicated at 1, which can be associated with either of the ski boot flaps to be secured together.
  • a first actuating element which advantageously comprises a small wheel 2 having a knurled outer surface 3 and an axial center pin 4 which performs the dual function of an axle and element of engagement with the body 1.
  • Said wheel 2 has on one face thereof a flat serration 5 extending circumferentially around said pin 4.
  • the wheel 2 is attached to the body 1 and held in position by a small cover 6 from which portions of the wheel periphery protrude sidewards to allow the wheel to be operated from the outside.
  • the wheel 2 interacts with a rotary to translatory motion conversion unit which advantageously comprises a pinion gear 10 arranged for rotation about a substantially perpendicular axis to the rotation axis of the wheel 2 and having an axially mounted nut screw 11 which engages with a threaded rod 12 which is acted upon by means effective to prevent the rod from rotating about its own axis, thereby the rotary motion imparted to the gear 10 is converted into a translation of the rod 12.
  • a rotary to translatory motion conversion unit which advantageously comprises a pinion gear 10 arranged for rotation about a substantially perpendicular axis to the rotation axis of the wheel 2 and having an axially mounted nut screw 11 which engages with a threaded rod 12 which is acted upon by means effective to prevent the rod from rotating about its own axis, thereby the rotary motion imparted to the gear 10 is converted into a translation of the rod 12.
  • the rod 12 is translatable within a recess 20 defined on the interior of the body 1 and is connected, at one end thereof, to a link 21 protruding out of the body 1 and having at its other end engagement means interacting with the other of the flaps to be secured together which may comprise either a ring or hook, in conformity with conventional practice.
  • the means which prevents the rod 12 from rotating may comprise a slot 30 formed through the body 1, wherethrough the link 21 projects outwardly which is advantageously of a foil-like shape; similarly, the rod may have a polygonal shank which engages in a corresponding recess 20 of polygonal shape.
  • the pitch of the thread of the rod 12 and nut screw 11 is a very fine one, so that, owing to the gear 10 engaging with the wheel 2, a considerable tensile force may be applied by virtue of the large speed reduction effect provided by the fine pitch thread, whereby by manipulating the wheel 2 it becomes possible to apply such a pull force as to enable the ski boot to be tightened without the assistance of the conventional lever; moreover, the provision of the mechanisms just described affords a very fine adjustment capability of the useful length and, hence, enables the user to adjust at will the tightening force.
  • the link element 21 may be provided with an indexed scale displaying its useful length, and consequently the applied pull force.
  • the body 1 may be hinge connected to a closure lever 50 attached to either of the flaps to be secured together, in which case the device would mainly perform an adjusting function, the fastening function proper of the fastening device being performed by the lever, which may be of conventional design.
  • the invention achieves its objects, and in particular that the provision of a geared device with a high redaction ratio, resulting from the fine pitch of the threads of the rod 12 and nut screw 11, enables the development of high tensile forces for an adequately small effort to operate the wheel 2.
  • the materials used, and the dimensions and contingent shapes may be any selected ones to meet individual application requirements.
