Definitions

  • the present invention relates to an alpine ski boot comprising a shell base surmounted by a rod which is at least partially articulated around an axis of the shell base between two support elements disposed on the one hand on the rod, and on the other hand on the hull base, and delimiting between them an angular amplitude of deflection in bending of the rod towards the front relative to an initial reference forward position from which said amplitude, and consequently the stiffness of the rod, possibly adjusted by means of an adjustment device connecting the support elements together.
  • an alpine ski boot comprising a shell base surmounted by a rod which has a front part and a rear part obtained in one or more pieces, and which is at least partially articulated around an axis of the base shell in a postero-anterior and / or antero-posterior direction, between two support elements arranged on the one hand on the rod and on the other hand on the shell base and delimiting between them an angular amplitude of deflection in bending of the rod towards the front, with respect to a reference initial advancement position from which said amplitude and consequently the stiffness of the rod can be adjusted by means of an adjustment device, interposed between the supporting elements, a minimum amplitude corresponding to a maximum stiffness, and vice versa.
  • the device for adjusting the amplitude, hence the stiffness of the rod is constituted by a flexible and inextensible link placed between the support elements, respectively of the articulated rod and of the shell base constituting attachment points. of said link, the course of which between these points can be modified to provide it with a state of maximum tension or a state of controlled relaxation which corresponds to a slack, so as to allow the rod an angular amplitude of forward deflection, predetermined and adjustable, via a control member acting on the link tension state directly or indirectly.
  • the initial advancement position of the upper is provided adjustable; for this purpose, the rear support element located on the shell base also serves as a rear support stop for the rod and is provided for this purpose with vertical adjustment means making it possible to position it at different heights.
  • the advantage of this arrangement lies in the fact that by adjusting the advancing angle by modifying the position of the rear support element, the operation of the device for adjusting the stiffness of the rod is not modified. because the relative position of the support elements of said device remains identical.
  • This advantageous arrangement of the advance adjustment which is associated with the stiffness adjustment device requires a disassembly-reassembly operation of the rear support element which proves tedious to be performed by the skier. Indeed, such an operation is difficult and long to execute, because not only is it necessary to have a disassembly-reassembly tool, but it is also necessary to identify the height position of the rear support element on the hull base after its adjustment to reproduce it identically on both skier's boots.
  • this maneuver which requires a certain dexterity, with a risk of loss of the dismantled part or parts, is made almost impossible for the skier.
  • the present invention aims to remedy these drawbacks by proposing a ski boot of the kind mentioned above with an adjustment of the advance which, coupled to a device for adjusting the stiffness, is easy to execute even under practical conditions. skiing and this, with ordinary means available to the skier such as keys, coins, strap end, etc., without the need to carry out a disassembly-reassembly maneuver, and without the advance adjustment does not influence the stiffness adjustment.
  • the ski boot comprises a shell base surmounted by a rod at least partially articulated around an axis on the shell base.
  • the rod is limited in angular movement by means of a device called "stiffness control" having two support elements arranged, one on the rod, and the other on a part belonging to the shell base, and connected between them by a link.
  • One of these support elements is associated with a rear support means or abutment of the rod intended to determine the initial position of advance thereof; it is characterized by the fact that it is rigidly associated with the rear support stop on a common axis of rotation thus constituting a rotary assembly, and by the fact that the support element and the rear support stop are both offset on the same side and the same value relative to the axis of rotation of said rotary assembly.
  • An advantage provided by this arrangement is that, when the rotary assembly is rotated, the advancing position of the rod and the position of the support element of the link of the stiffness control device are simultaneously modified according to quantities. inversely proportional variables. Therefore, the length of the link between the two support elements of the stiffness control device remains constant regardless of the rotational position of the rear support stop: there is therefore no incidence of adjustment of the advance on the stiffness control despite the coupling of these two distinct functions.
  • the rotary assembly remains fixed in position on the part of the shoe on which it is mounted; in fact, this avoids having to locate the position in height of the rear support stop on the shell base or on the rod. Furthermore, in the case of carrying out a simple rotary operation of the rotary assembly to adjust the advance of the rod, and not of disassembly, the use of specific means and / or tools is not not required, and the execution time for such an operation is very short. It is obvious that the rotary assembly is advantageously provided with a means such as an imprint or a projection intended to allow its maneuver in rotation, manually with or without the aid of an ordinary means normally available to a skier. , for example a coin, a strap end, a key, etc ...
  • the rotary assembly comprises a shoulder constituting the rear support stop for adjusting the advance and a pulley constituting the support element of the stiffness control device whose contour is progressive, for example 360 ° or simply 180 °.
  • an indexing means can be associated with the rotary assembly to maintain it in the position of its rotation adjustment carried out.
  • the rotary assembly can be indifferently mounted on the upper of the shoe or on a part belonging to the shell base since its role is to intervene between them to cause their relative pivoting around their connecting axis.
  • the support element and the rear support stop which form the rotary assembly are provided more or less eccentric with respect to their axis of rotation as a function of the maximum value of the advance change of the rod to be produced; in fact, the value of the offset determines directly that of the variation of advance.
  • the ski boot 1 of the type with front and / or central entry, comprises an adjustable collar-collar 2 on the lower leg of the skier using flaps transverse 3 and closing systems 4.
  • the stem-collar 2 is articulated around an axis 5 located on a shell base 6 substantially in the region of the malleoli.
  • the shoe 1 has in the dorsal zone of the heel of its shell base 6 a vertical notch 7 open upwards, and closed by a retractable flap 8 hinged 9 at its lower part on the shell base in the lower zone 46 of the heel .
  • This flap 8 which closes the notch 7 in the shoe use position for the practice of skiing by blocking the rear rod 2, is intended to allow the passage of the heel of the skier's foot to facilitate putting on and taking off.
  • the rearward locking of the rod is obtained by means of the upper part of the flap 8 which is adjusted by a support zone 11, in the skiing practice position, under a rear support stop 10 carried by the stem-collar.
  • the latter is limited in angular deflection for pivoting forwards by means of a stiffness control device 12.
  • This device 12 has, on the one hand, two support elements 13 and 14 arranged one, 13 , on the rod 2, and the other, 14, on the flap 8 belonging to the shell base 6, and on the other hand, a link 15 which connects these elements 13 and 14 together.
  • This link 15 is adjustable between a state of maximum tension, providing the blocking of the collar rod 2 forwards and a more or less significant state of relaxation providing a certain freedom of pivoting forwards of said rod 2.
  • the link 15 is adjusted by translational displacement of the support element 14 on the threaded rod 17 of a pivoting lever 18.
  • the lever 18 is articulated, 19, in the upper region of the flap 8 and closes by tilting down, either manually or automatically, for example using a "pin" spring 20 interacting between it and the flap 8.
  • the flap 8 is kept in closed position under the stem-collar 2, that is to say that the rear support stop 10 remains permanently opposite its support zone 11.
  • the flap 8 follows the forward bending movements of the collar rod 2; for this purpose, an elastic means 21, such as a spring, may be provided to interact between the flap 8 and the shell base 6, and thus permanently ensure the return and the maintenance of the flap 8 in locking under the rod- collar 2.
  • an elastic means 21 such as a spring
  • the support element 13 of the stiffness control device 12 is rigidly associated with the rear support stop 10 on a common axis of rotation 16, materialized in this example by a cylindrical bearing coming from said stop 10, thereby forming a rotary assembly 10-13; this assembly has on the one hand a pulley which constitutes the support element 13 of the stiffness control device 12, and on the other hand, a shoulder, or rear support stop 10, on which the collar rod 2 leans backwards.
  • the support element 13 and the stop 10 are both eccentric on the same side and of the same value relative to the axis of the rotary assembly as illustrated, by way of example , in Figure 1A; in fact, the external contour of the eccentric rear support stop 10 with reference to the axis of rotation 16 gives a value difference corresponding to BA which is equivalent to that of B'-A 'of the support element rear 13.
  • the rear support stop 10 is provided with a recess 22, for example a screwdriver slot sufficiently wide and long to allow the use of a coin, key, strap end, etc. It is understood that the rear support stop 10 can, unlike a slot, be provided with a projection intended to be entered manually or with the help of an ordinary tool for its rotation.
  • the ski boot 30 of the rear entry type is provided with a device for adjusting the stiffness 12 comparable to that of FIGS. 1 to 5; the latter comprises, as before, two support elements 13-14 and a link 15.
  • the length of this link is adjusted by means of a rotary cam 32 which, controlled by a rotary button 33, more or less repels the 'support element 14 of the fixed one, 13, thus varying the tension or the relaxation of said link 15, and therefore the possibility of forward bending of the rod 34.
  • This rod 34 is obtained in two parts, a cuff 35 articulated 5 on the shell base 6, and a rear cover 36 articulated, 39, on rear legs 37 coming from said cuff.
  • the stiffness control device 12 is, in this construction case, integrated into the rear part of the rod 34 formed by the rear cover 36, and the fixed support element 13 associated with the rear support stop 10 is mounted in the lower zone 46 of the heel of the shell base 6.
  • the bearing zone 31 intended to cooperate with the stop 10 is, in this case, formed on the lower part of the rod 34 located opposite.
  • the ski boot 40 is of the front entry type and comprises a collar rod 44 which extends to the lower zone 46 of the heel of the shell base 6.
  • the device for controlling the stiffness 12 with its two support elements 13 and 14 and its link 15 has, in this example, a support reference 45 for the link 15; the latter is adjusted in tension by means of the support element 14 which is displaceable in translation on a threaded rod 17 of the lever 18.
  • the ski boot 50 is of a type with front entry and is comparable to that described with reference to FIGS. 1 to 5, the essential difference residing in the fact that the dorsal zone of the heel of the base shell 6 is closed, that is to say that it is not open by a notch provided with a retractable flap for passage of the heel.
  • the support zone 11 is obtained on the upper part of the heel of the shell base 6 opposite the rear support stop 10 carried by the collar rod 54.
  • the support element 13 and the rear support stop 10 have a contour which is gradually variable over 180 °.
  • a known indexing means is intended to block the rotary assembly 10-13 in any intermediate position located between the two extreme positions determined by their eccentricity. In this way, the advance can be adapted according to a multitude of positions.
  • this variable contour over 180 ° is not progressive and in particular that it is in the form of a rectangle so that only two advance positions are obtained for the rod 2, 34 , 44, 54, shoe 1, 30, 40 and 50.
  • the rotary assembly 10-13 can be free to be rotated through 360 ° or be limited to a lower angle, and that the outline of the support element 13 and the rear support stop 13 can also be progressive over 360 ° or at a lower angle.
