Definitions

  • the present invention relates to an alpine ski boot, comprising a shell bottom on the rear part of which is mounted at least partially pivoting, around an axis transverse to the longitudinal axis of the shell bottom, the upper of the boot.
  • Alpine ski boots with pivoting rod offer the advantage, compared to the shoes used previously, with rod forming a single piece with the bottom of the boot, that the rod can follow the movements of bending forward and towards the back of the lower leg of the skier, while walking and skiing, and that this rod can also tilt backwards, totally or partially, to facilitate putting on and taking off.
  • the pivoting rod can be made in one piece and it then forms a collar surrounding the entire lower leg. It can also comprise two constituent parts, namely a front part or cuff, covering the instep, integral with the bottom of the hull or pivoting on this bottom of the hull, and a rear part or rear cover, surrounding the rear of the lower leg.
  • the present invention relates to improvements made to the aforementioned alpine ski boots with the aim of obtaining increased rigidity with respect to postero-anterior or antero-posterior supports during skiing.
  • this alpine ski boot comprising a shell bottom and a rod pivotally mounted on this shell shell, about a horizontal and transverse axis, the rear part of the rod comprising a rear wall extending along from the back of the lower leg of the skier, is characterized in that the rear wall of the rod is consolidated by a one-piece stiffening spacer which extends, at a distance from the rear wall of the rod, between the upper parts and lower of this rear wall, and in that at least one tie establishes a rigid mechanical connection between an intermediate zone of the stiffening spacer and an intermediate zone of the rear wall of the rod.
  • the alpine ski boot with rear entry which is represented in FIGS. 1 to 3, comprises a rigid shell bottom 1 and, at its upper part, a rod 2 surrounding the bottom of the leg of a skier, shown in phantom.
  • the rod 2 is in one piece and it forms a collar, the two anterior end parts of which overlap one another.
  • This collar 2 is pivotally mounted, at its lower and rear part, on the shell bottom 1, around a horizontal and transverse pivot axis 3 carried by the rear wall 1 a of the shell bottom 1.
  • the collar 2 carries, at its upper part, a lower leg tightening device, of any known type, comprising a cable or a tightening strap 4, and, at its lower and front part, a device 5 for tightening the collar 2 on the lower shell 1.
  • This collar 2 comprises two lateral parts 2a which are pierced with holes aligned transversely and horizontally and, in these holes, engage respective studs 6 carried by the lateral parts 1 of the bottom of shell 1 and projecting towards the outside. These pins 6 serve to immobilize the collar 2 on the bottom of the shell 1, when this collar 2 is tightened on the bottom of the shell by means of the device 5.
  • the collar 2 also includes a rear wall 2b which is inclined from the bottom upwards towards the front, in the skiing practice position, as shown in FIG. 1.
  • This rear wall 2b can be flat or else it can have a curved shape so as to follow as closely as possible the profile of the back of the lower leg of the skier drawn in phantom in Figure 1. Therefore the rear wall 2b has, seen from the side, a concave shape towards the rear, with large radius of curvature. Due to this concave shape, the rear wall 2b of the collar 2 offers reduced resistance to the forces which result from the anteroposterior and posterior anterior supports of the skier during skiing.
  • a one-piece stiffening spacer 7 extends between the upper part and the lower part of the rear wall 2b of the collar 2.
  • the one-piece stiffening spacer 7 extends between an upper connection zone 8 , close to the upper edge of the collar 2, and a lower connection zone 9, close to the lower pivot axis 3 of the collar 2.
  • This stiffening spacer 7 can be constituted by an insert, fixed at its upper ends and lower, to the collar 2 or alternatively, which is preferable, it can be formed in one piece with the collar 2 coming from molding with the latter, as shown in the drawing.
  • the stiffening spacer 7 can be straight or, preferably, it can have a slight rearward convexity so that the rear wall 2b and the stiffening spacer 7 jointly form, seen from the side, a kind of spindle .
  • the stiffening of the rear wall 2b of the collar 2 is also ensured by at least one tie rod 11 connecting an intermediate zone of the stiffening spacer 7 and an intermediate zone facing the rear wall 2b of the collar 2, so as to prevent said zones can deviate from or approach each other.
  • the shoe may comprise a single stiffening tie 11 as shown in FIGS. 1 to 3.
  • the single stiffening tie 11 extends substantially between the median zones of the rear wall 2b and of the stiffening spacer. 7, that is to say the zones most exposed to buckling.
  • the stiffening rod 11 is inclined from bottom to top and from front to back.
  • the stiffening spacer 7 can have a constant width from top to bottom or alternatively, as it appears more clearly in FIG. 3, this width can decrease from top to bottom from the upper connection zone 8 to the intermediate zone where the tie rod 11 is located and then gradually increasing to the lower connecting zone 9.
  • the stiffening spacer 7 is connected to the rear wall 2b of the collar 2 by means of two tie rods 11 a which are substantially perpendicular to the rope A, drawn in phantom , extending between the two upper 8 and lower 9 connection zones.
  • FIG. 5 represents an alternative embodiment in which the stiffening spacer 7 is connected to the rear wall 2b of the collar 2 by means of two parallel tie rods 11b inclined up and down towards the front.
  • the inclined tie rod (s) are substantially parallel to a straight line passing through the front end of the sole of the shoe and through a point located halfway up the upper.
  • FIGS. 1 to 5 The shoes which have just been described with reference to FIGS. 1 to 5 above include a collar 2, the lateral parts 2a of which hang onto pins 6 carried by the lateral parts 1 of the bottom of the shell 1. It is obvious that the embodiment a stiffening beam according to the invention can advantageously be applied to boots not provided with such an attachment of the upper and also to ski boots of a type different from that with "rear entry"; by way of nonlimiting examples, FIGS. 6 to 8 which follow schematically illustrate shoes of different types in which:
  • FIG. 6 represents an alternative embodiment of the invention applied to a ski boot of the central entry and / or rear type, the upper 2 of which consists of two independent parts, namely a front cuff 14 and a hood aft 15. These two independent parts are articulated, at their lower parts, on the shell bottom 1, around a common horizontal and transverse axis 16.
  • the stiffening spacer 7 and the tie rod (s) 11 are part integral of the rear cover 15.
  • the spacer 7 extends between the upper 8 and lower 9 parts of the rear wall 15a of the rear cover and the tie rod (s) 11 extend between the spacer 7 and the rear wall 15a of the cover rear 15.
  • FIG. 7 illustrates a ski boot of the mixed entry or top entry type in which the upper 2 has a rear cover 25 which is capable of tilting in the anteroposterior direction around an axis 16, while the front cover 24, consisting of a one-piece cover, is articulated in the area of the toe of the shoe by means of an articulated link 23 to allow putting on and / or taking off from above the shoe .
  • the stiffening beam 7 is connected to the rear wall 25a of the rear cover 25 by means of its two connection ends 8, 9 and by means of two tie rods 11 c parallel to each other and inclined by top to bottom back.
  • FIG. 8 shows a ski boot of the mixed entry type in which the upper 2 comprises a collar 35 for holding the lower leg and an anterior part 34 coming from the bottom of the shell 1 intended to be gripped by said collar 35.
  • the part anterior 34 of the rod is, in this construction method, constituted by a transverse tongue 30 which overlaps another tongue 30a, opposite, the two tongues extending respectively, from a flank of the bottom of shell 1. It is thus possible to open the zone of the shoe corresponding to this front part 34 after release of the collar 35 for the introduction or the extraction of the foot by spacing of said tabs.
  • the stiffening beam 7 is connected in its central region to the rear wall 35a of the collar 35 by means of two tie rods 11 substantially arranged in a V shape from said wall 35a. It is obvious that the tie rods 11 d can be inclined relative to each other at different angles and be more or less distant from one another without leaving the framework of the invention.
