Definitions

  • the present application relates to a device for adjusting the position of the bootleg with respect to the shell, particularly for ski boots.
  • U.S. Pat. No. 4,519,150 is known in which a ski boot is disclosed that is comprised of a shell to which a bootleg is pivoted, to the rear of the bootleg a lever being associated the actuation of which enables the activation of a bar that has a threaded end which interacts with a counter-threaded bush which can be arranged on an adapted abutment coupled to the shell.
  • adapted elements which can be activated for example by way of adapted levers that can be gripped by the user and selectively positioned so as to allow the free oscillation of the bootleg or limit the oscillation thereof, by way of their interaction with adapted projecting parts at and outside of the shell.
  • Such projections however constitute a further drawback, given that they impair the aesthetic form of the boot as well as making it heavier.
  • EP0940096 in which a device is disclosed for adjusting the position of the bootleg with respect to the shell, particularly for ski boots, constituted by at least one lever, composed of a first and a second arm, mutually and rotatably associated at one end by means of an adapted first pivot arranged transversely and to the rear of the shell.
  • the first arm is positioned in a region that lies above the heel of the shell.
  • the lever has a first end that interacts with a coupling, which is coupled to a ski, in contrast with at least one first elastically deformable element and a second end that selectively interacts, in abutment or otherwise, with the bootleg.
  • EP0085026, EP0521283, EP0582803, E0664969 and FR2647649 which all exhibit a high structural complexity and considerable encumbrances, as well as the necessity for a manual activation by the user.
  • EP0664969 which, although allowing an activation when the boot is anchored to the ski binding, still has a considerable encumbrance at the rear of the bootleg, which moreover extends in a lower region almost to the sole, as well as a high structural complexity and an operation that requires high precision for achieving for example the optimal interaction between the tab and the seats, where it is possible for them to stick and thus thwart the operation.
  • the aim of the present invention is to eliminate the above-mentioned drawbacks, and thus solve the technical problems set out, by devising a device that enables the user to obtain the free oscillation of the bootleg in order to walk or a limitation of such oscillation in order to be able to ski, the assembly being provided with a structural shape that is simple and of contained size.
  • an object of the invention is to enable the skier to achieve such two different conditions for the oscillation of the bootleg with respect to the shell automatically and thus without having to operate directly on adapted devices applied at the boot itself and irrespectively of the possible presence of snow or ice on the boot.
  • Another object is to provide a device that in addition to the above-mentioned characteristics also is relatively low-cost and enables an abatement of the overall costs, including a reduction in the provision of molds and for the mounting of the device on the boot.
  • Another object is to provide a device the activation of which, for skiing, and the deactivation of which, for walking, can be obtained without any direct intervention of the skier on the boot.
  • a device for adjusting the position of the bootleg with respect to the shell, particularly for ski boots characterized in that the first end of a blade is associated internally and at the rear with respect to said bootleg, said blade interacting selectively, at the second end, with a tooth of a slider, which is arranged adjacent to the heel and movable axially with respect to said shell in contrast with an elastically deformable element.
  • FIG. 1 is a partially sectional view of a boot with the device in the condition that allows skiing;
  • FIG. 2 is a view of a detail of FIG. 1 ;
  • FIG. 3 is a partially sectional view of the boot with the device in the condition that allows walking;
  • FIG. 4 is a sectional view taken along the line IV-IV of FIG. 3 ;
  • FIG. 5 is a view similar to FIG. 1 wherein a condition of automatic rearming of the device is shown;
  • FIG. 6 is a first view from the rear of the boot
  • FIG. 7 is a second view from the rear of the boot
  • FIG. 8 is a side perspective view of the slider and the blade
  • FIGS. 9 , 10 and 11 are views from above of a cross-section, taken along an axial and lateral line, of the slider in the uncompressed condition;
  • FIGS. 12 , 13 and 14 are views from above of a cross-section, taken along an axial and lateral line, of the slider in the compressed condition.
  • the reference numeral 1 designates a ski boot constituted by a shell 2 to which, by way of adapted bosses 3 , a bootleg 4 is pivoted.
  • the reference numeral 5 designates the device for adjusting the position of the bootleg 4 with respect to the shell 2 , such device being constituted by a blade 6 , a first end 7 of which is associated, preferably by means of an adapted rivet 8 , internally and to the rear with respect to the bootleg 4 .
  • the first end 7 of the blade 6 is adjacent to the lower perimetric edge 9 of the bootleg 4 in a region that lies above the inner lateral edge 10 of the shell 2 .
  • the blade 6 is directed toward the underlying heel 11 of the boot and is locked to the bootleg 4 so that it cannot oscillate with respect to the rivet 8 .
  • the locking occurs at the first end 7 by the partial bending and interpenetration thereof in the thickness of the bootleg 4 .
  • the blade 6 is thus caused to pass through an adapted opening 30 defined in the shell 2 and thus arranged adjacent to the inner lateral surface 12 of the shell 2 , and has a second end 13 that extends so as to affect partially a recess 14 provided in the heel 11 .
  • a first longitudinal slot 15 is provided which acts as a seat for temporary interconnection with a tooth 16 .
  • the tooth 16 is frustum-shaped with the vertex directed toward the outside of the shell 2 and the first slot 15 is shaped complementarily thereto.
  • the tooth 16 protrudes axially with respect to a slider 17 movable axially with respect to a box-like body 18 which is embedded in or associated with the lower end of the shell in a region that is adjacent to the flat surface 19 of the heel 11 which interacts with a jaw 20 of a coupling 21 which is coupled to a ski 22 .
  • the slider 17 is connected to the blade 6 and protrudes outside the box-like body 18 and also outside the shell 2 to be able to thus interact with the jaw 20 , once the boot has been associated with the ski.
  • the slider 17 has, in a transverse cross-section, the shape of an inverted T the stem 23 of which slides within a seat 24 and the wings 25 a , 25 b of which slide within complementarily shaped guides 26 a , 26 b provided at the sides of the box-like body 18 .
  • a transverse pin 27 connects the wings 25 a , 25 b and whose ends protrude outside the box-like body 18 at adapted second slots 28 a , 28 b formed on the sides of the box-like body 18 .
  • the transverse pin 27 is arranged approximately halfway along the length of the box-like body 18 , so as to create a space, in the opposite direction with respect to the slider 17 , which acts as a seat for an elastically deformable element 29 , such as a cylindrical helical compression spring, the function of which is to force the slider 17 toward the outside of the shell 2 .
  • an elastically deformable element 29 such as a cylindrical helical compression spring
  • This cross-member 27 acts as a stroke limit for the slider 17 .
  • a counter 31 is provided which is arranged inside the shell 2 and has a rear surface 32 which faces the blade 6 and a lower surface 33 which is arranged above the box-like body 18 and is associated with the shell 2 by means of a screw 34 which operates on a vertical rib 35 of the shell 2 or of a platform located in a region that is adjacent to the recess 14 .
  • One or more sealing gaskets can be present, which are arranged for example between the slider 17 and the shell 2 or between the box-like body 18 and the shell 2 so as to prevent any penetration of water into the heel 11 .
  • the box-like body 18 is fixed to the shell 2 at the end that lies opposite the one provided with the slider 17 by means of a pair of second screws 36 a , 36 b which engage adapted holes 37 a , 37 b provided in a pair of tabs 38 a , 38 b that protrude laterally to the box-like body 18 .
  • the operation of the invention is as follows: during skiing the system is in the condition shown in FIG. 1 , in which the jaw 20 forces the slider 17 to position the tooth 16 within the first slot 15 of the blade 6 .
  • the rearward oscillation of the bootleg 4 is prevented, although a slight bending forward of the bootleg 4 is permitted if the length of the first slot 15 is greater than the encumbrance of the tooth 16 .
  • FIG. 5 shows a condition in which the second end 13 of the blade 6 can be positioned within the recess 14 .
  • the invention has achieved the above-mentioned set aim and objects, a device having been obtained that enables the user to obtain the free oscillation of the bootleg in order to walk or a limitation of such oscillation in order to be able to ski, the assembly being provided with a structural shape that is simple and of contained size.
  • the skier can achieve such two different conditions for the oscillation of the bootleg with respect to the shell automatically upon engagement and upon release of the coupling even in the presence of snow or ice on the boot.
  • the device moreover has a small number of components which makes it possible to achieve construction-related simplification.
