Definitions

  • the present invention relates to the general technical field of equipment intended for the practice of alpine skiing or its derivatives, and relates, more particularly, to the specialized technical field of ski boots.
  • ski boots are based on two general principles which consist in ensuring ankle protection and good handling of the skis.
  • a simple way to achieve this is to block the ankle in the shoe, which considerably reduces the trauma of this joint and which allows the leg to be joined to the ski, the ski being then driven by the only joints of the knee and hip.
  • Such shoes have the drawback of preventing physiological movements of the ankle which take place in the three planes of space, namely the frontal plane, the horizontal plane and the sagittal plane.
  • Blocking ankle movements has the disadvantages of reducing the adaptability of the foot through the ankle to the ground and greatly reducing, if not completely, the possibilities of escape of the lower limb when the foot is blocked ground.
  • This non-compliance with the physiology of the ankle joint leads, in the event of a fall in particular, to an increase significant of the mechanical stresses on the knee and, in particular, on the ligament system. The frequency and severity of ligament injuries to the knee are therefore greatly increased with this type of shoe.
  • ski boots have a plantar shell including an upper and a stem articulated on the plantar shell above the tibio-tarsal joint around an axis substantially parallel to the plane of extension of the sole.
  • This type of realization present, certainly, the advantage of allowing a certain degree of flexion of the ankle around the axis of tibio-tarsal articulation and therefore in the saggital plane, but this type of realization always maintains the articulation of the ankle in a completely blocked state, in the frontal or horizontal plane.
  • the rod is mounted so as to be able to adapt to the anatomy of each skier, by sliding along a substantially vertical axis.
  • Such an assembly does not however allow movement of the ankle in a horizontal plane, which allows no angular movement, even partial, comparable to the natural movements of the natural ankle joint.
  • This shoe makes physiological ankle movements impossible, since any movement in the frontal plane of the ankle is accompanied by movement in the plane horizontal and, to a lesser degree, in the sagittal plane.
  • the object of the present invention is therefore to remedy the drawbacks of ski boots of the prior art for producing a ski boot which respects, at least partially, the physiology of the ankle joint, without compromising its protection. and skiing, while reducing the risk of knee ligament damage.
  • Another object of the invention consists in making a ski boot allowing simultaneous movements of the foot in the horizontal and frontal planes.
  • a secondary object of the invention is to provide a ski boot allowing improved reproduction of the ankle joint in the saggital plane.
  • a ski boot comprising, on the one hand, a plantar shell provided with a sole and an upper area intended to rest directly or indirectly on a support, such as a ski, for example, and able to contain at least the plantar base of the foot and the calcaneus-pedous block and, on the other hand, a rigid rod adaptable to the so-called shell and capable of enveloping and supporting the tibio-tarsal articulation of the ankle, the shell and the rod being mounted with relative freedom of movement.
  • the rigid envelope is a rod capable of supporting and enveloping the tibio-tarsal articulation of the ankle and the talus, mounted and adapted in leaktight manner on the shell by means of the articulation device, which is mounted to allow a relative angular movement of the rod and the shell, according to at least one freedom of movement whose instantaneous axis or axes of movement are circumscribed inside a geometric envelope in the shape of a cone of revolution called sub-talus cone and representative of eversion and inversion movements.
  • Fig. 1 shows a schematic external lateral view of the ankle and foot joint in a ski boot according to the invention.
  • Fig. 2 shows the ankle joint according to a top view taken from FIG. 1.
  • Fig. 3 shows a first embodiment according to a longitudinal section of a ski boot according to the invention.
  • Fig. 4 shows a sectional view of a first embodiment of a shoe according to the invention taken according to a section made along the line IV-IV of FIG. 3.
  • Fig. 5 shows a detail of the articulation device according to the invention taken according to section VV of FIG. 3.
  • Fig. 6 shows a detail of the articulation device according to the invention taken according to section VI-VI of FIG. 3.
  • Figs. 7 and 8 illustrate alternative embodiments of the articulation device according to the invention.
  • Fig. 9 shows a view of a ski boot according to the invention taken from a rear view of the boot.
  • Figs. 10 and 11 illustrate another alternative embodiment showing a particular assembly of the two parts of the shoe.
  • Fig. 1 shows, schematically, the distribution of the bones constituting the subtalar joint of the ankle of a human inside a ski boot whose outer shell 1 , as well as the sole 2 , have have been shown in dotted lines.
  • the general view represented can be considered as illustrating the position of the ankle and the right hindfoot of a skier, seen laterally from the outside, in a plane extending in the direction of the main longitudinal axis of the shoe, and substantially perpendicular to the support and extension plane of the shoe materialized by the plane P considered as the support and extension plane of the sole 2 of the shoe.
  • the subtalar joint of the ankle consists of the calcaneus 3 , the talus 4 , the assembly consisting of the cuboid 5 , the scaphoid 6 , the cuneiforms 7 , then the metatarsals and, finally, the phalanges, not shown on fig. 1, forming the calcaneopedious block.
  • the movements of the subtalar joint in space can be considered to be the result of the relative positions in space of all the positions of the calcaneus-pedious block consisting of the calcaneus 3 , the cuboid 5 , the scaphoid 6 and cuneiforms 7 and metatarsals 8 relative to the talus 4 . More precisely, these movements are defined conventionally in anatomy by an inversion movement, and by an eversion movement of the ankle.
  • amplitudes given above by reference correspond to average values, each amplitude being capable of varying more or less 5 to 10 degrees depending on the age of the individual, as well as according to their own anatomical characteristics.
  • the apex S of the cone 11 can be considered to be situated at a distance d behind the calcaneus and at a height H1 substantially equivalent to one third of the height H representative of the height of the extreme posterior edge of the calcaneus 3 .
  • the vertex S is also located at the center of the geometric projection of the calcaneus 3 on the frontal plane F.
  • the determination of the inclination of the cone 11 relative to the plane P can be defined by means of the two bundles of hedged ligaments 12 and 13 , the intersection of which must be located on the central axis 14 of the cone 11 .
  • the angle ⁇ formed by the intersection of the central axis 14 of the cone 11 with the plane P , has a value between 20 and 50 ° and, preferably, between 30 and 45 °.
  • the cone 11 is further defined by its opening angle ⁇ whose average value varies between 15 to 30 ° depending on the age of the individuals and their anatomical particularities.
  • Fig. 2 represents a right foot, in top view, inside a shoe 1 .
  • the axis xx ′ represents the longitudinal axis of the shoe 1 .
  • the axis xx ′ and the central axis 14 of the cone 11 form an angle ⁇ between 10 and 30 °, the cone 11 being, consequently, directed towards the inside of the foot.
  • Fig. 3 illustrates a first embodiment of a shoe according to the invention and consisting of a plantar shell 15 provided with a sole 2 intended to rest directly or indirectly on a support materialized by the plane P.
  • the plantar shell 15 is able to serve as a support for the plantar base of the foot and to contain at least part of the dorsal mass of the foot, including the calcaneus-pedious block, via a vamp area 16 .
  • the shoe according to the invention is furthermore composed a rigid rod 17 which can be tightly adapted to the plantar shell 15 and which is capable of enveloping and supporting the ankle joints and, in particular, the tibio-tarsal joint 10 and the talus 4 , both laterally and anteriorly and later.
  • the adaptation of the rigid rod 17 on the plantar shell 15 is carried out by means of an articulation device which, in the example shown in FIG. 3 , comprises two connecting means between the plantar shell 15 and the rigid rod 17 , in order to allow relative angular movement of the shell and the rod.
  • the first connecting means 22 ( fig. 3 and 6 ) is disposed on the rear part of the boot in the area intended to accommodate and serve as a reception seat at the heel of the skier and consists of a lug 23 integral with the shell plantar 15 and comprising a head, spherical or hemispherical for example, engaged with a mounting clearance inside a cavity 24 formed inside the thickness of the terminal section 25 of the rigid rod 17 .
  • the lug 23 and the cavity 24 are arranged and produced on the shoe in the vicinity of the vertex S of the subtalar cone 11 , so that the relative movement of the plantar shell 15 and the rigid rod 17 takes place around instantaneous axes confined inside the sub-talus cone 11 previously defined.
  • the freedoms of movement allowed by the posterior connecting means 22 can consist of rotations around an axis A1 directed from the rear part of the shoe towards the front part of the boot inside the cone 11 and / or in rotations around an axis A2 of direction coincident with the longitudinal axis of the support part of the rotation head of the lug 23 , the axis of rotation A2 being obviously confined to the interior of the subtalar cone 11 .
  • the posterior connecting means 22 allows a combination of the rotations previously defined and, advantageously, any connecting means will be used ensuring a relative displacement of the hull plantar 15 and rigid stem 17 in the three planes of space.
  • the two cavities 26 and 27 are preferably semi-spherical, provided with annular relief zones and formed, respectively, in the thickness of the rigid rod 17 and the plantar shell 15 , these same cavities 26 and 27 serving as a receiving seat for a ball joint 28 permanently fixed by any appropriate means to the plantar shell or the rigid rod.
  • Such an assembly, with relative clearance, also ensures relative angular movement in the three directions of the space of the plantar shell 15 relative to the rigid rod 17 .
  • the articulation device of fig. 3 is completed by an anterior connection means 32 advantageously disposed between the upper region 16 of the plantar shell 15 and the anterior part 17 a of the rigid rod 17 .
  • the anterior connecting means is disposed at least partially in the subtalar cone 11 , so that the instantaneous axes of displacement of the plantar shell 15 and rigid stem 17 in the three planes of space are located inside the subtalar cone 11 .
  • the head of the lug 33 is mounted inside a receiving cavity 35 formed in the thickness of the front part 17 a of the rigid rod, the head of the lug 33 being held in place inside of the cavity 35 via an annular shoulder 36 internal to the cavity 35 .
  • Figs. 4 and 5 show that the cavity 35 can advantageously have a cross section of decreasing elliptical shape from the annular shoulder 36 to the bottom of the cavity, to allow, in association with the relative clearance for mounting the lug 33 to the inside the cavity 35 , a completely free movement of the plantar shell 15 relative to the rigid rod 17 .
  • the lug 33 can move parallel to the plane P to come occupy a position on the axis B1 or B2 for example.
  • these displacements can, of course, be combined with angular rotations of the plantar shell 15 or of the rigid rod 17 around the axis of instantaneous displacement constituted by the axis of the cylindrical base 34 and materialized for example by the passage of the central imaginary plane R of the rigid rod in the positions R1 and R2 .
  • the relative angular deflections of the plantar shell 15 with respect to the rigid rod 17 are limited, on the one hand, by the relative play of the two anterior and posterior means of articulation and, on the other hand, by means of stop formed at the junction and nesting zone 41 between the plantar shell 15 and the rigid rod 17 .
  • the lower stop can thus be constituted by the upper edge 42 of the upper limit of the plantar shell 15 .
  • the upper stop is then formed by the lower edge 43 of the lower limit of the rigid rod 17 .
  • the articulation device thus described is advantageously provided with an elasticity which can be imparted by the interposition on the two lateral edges of the shoe and between the plantar shell 15 and the rigid rod 17 , of spring dynamometers 44 , as illustrated in fig. 9 .
  • the spring dynamometers 44 are usefully provided with a system for adjusting the tension of the spring in order to ensure an adjustment of the flexibility of the relative angular movement between the plantar shell 15 and the rigid rod 17 . It is obvious that any elastic system equivalent ensuring controlled stiffening of the articulation device 21 can be envisaged without departing from the scope of the invention.
  • Fig. 7 shows, in a sectional view, a detail of an alternative embodiment of the anterior connection means 32 , which may consist of a double ball joint 45 comprising a central cylindrical body 46 supporting two spherical ball joints 47 and 48 at its two extremities.
  • the receiving seats of the ball joints 47 and 48 consist of cavities 49 and 50 identical to the cavity 35 of the variant illustrated in FIG. 3 and formed respectively in the front wall 17 a of the rigid rod 17 and in the upper region 16 .
  • the cavities 49 and 50 open to the outside of the front wall 17 a and of the upper zone 16 by two cylindrical bores 51, 52 traversed by the cylindrical body 46 .
  • the relative dimensioning of the double ball 45 , the cavities 49, 50 and the cylindrical bores 51 and 52 is provided to ensure, on the one hand, the retention of the double ball 45 inside the cavities 49 and 50 and, d on the other hand, to ensure an angular movement in the three planes of the space of the rigid rod 17 relative to the plantar shell 16 , and this around instantaneous axes of displacement confined inside the subtalar cone 11 .
  • a particularly advantageous and practical assembly of the anterior and posterior connecting means consists in placing the respective geometric centers of the posterior 22 and anterior connecting means 32 on the central axis 14 of the subtalar cone 11 . Due to the plasticity of the soles of the sole, it is however possible to arrange the said geometric centers in a vertical plane including the major central and longitudinal axis xx ′ of the ski boot.
  • Fig. 9 shows a view of the rear or rear face of a shoe for a right foot according to the invention.
  • the illustrated arrangement has an arrangement in which a rigid upper rod 55 is articulated relative to the rod 17 about an axis yy ′ transverse to the median plane longitudinal M of shoe 1 .
  • the axis yy ′ of the joint 56 is disposed on the shoe 1 , so as to extend substantially at the level of the tibio-peroneal clamp representative of the tibio-tarsal joint 10 (see fig. 1 ) of the ankle joint, in order to accommodate the flexion of this joint.
  • the transverse axis yy ′ is inclined relative to the main support and extension plane P of the shoe and rises progressively from the outside towards the inside of the shoe.
  • the axis yy ′ has an inclination of the order of 15 to 25 ° relative to the plane P.
  • sealing problems resulting from the production of a ski boot in at least two parts will be resolved by the interposition of sealing tabs arranged inside or outside the boot and for example along the area junction 41 .
  • Figs. 10 and 11 illustrate an alternative embodiment in which the articulation device consists of two bars 51 interposed laterally, between the shell 15 and the rod 17 .
  • Each bar 51 is secured to the shell 15 by a lower immobilizing element 52 , of the screw, rivet or similar type, and by an upper fixing element 53 , of the screw, tenon, rivet or insert type, for example.
  • the upper fixing element 53 and the bar 51 have a relative mounting clearance allowing movements of the rod 17 in the three planes of space, around instantaneous axes of movement whose geometric result moves in the cone 11 to respect the ankle joint. It is, of course, possible to reverse the respective positions of the elements 52 and 53 without departing from the scope of the invention.
  • the ski boot according to the invention allows, thanks to the articulation device, a reproduction, at least partial and, preferably, total, of all of the movements of eversion and inversion of the calcaneus-pedal block under the astragalus, without compromising the performance of the skier and the maintenance of the foot and ankle.
  • the definition of a geometric and mechanical model representative of the kinematics of the movements of the ankle joint on anatomical and physiological bases led to the definition of the sub-talus cone 11 making it possible to reconcile elements up to present at odds, namely the safety and performance of the skier.
  • the posterior connection means 22 could thus simply consist of a posterior junction zone between the rod 17 and the shell 15 , the said zone comprising, essentially, an elastically deformable plastic material.
