Description

The invention relates to a shoe intended for the production of

  mountain ski or hiking tick and including a co-

  that rigid inferior carrying the semells and a rod articulated by

  worn in a rigid shell around a transverse axis.

  This type of shoe, by the adjustable articulation or not of the rod on the ooque, represents a certain improvement compared to the previously known shoes, however it leaves only very

  little freedom of movement for skiing and walking in good conditions

  comfort, a fairly wide range of flexion of the ankle 0 being highly desirable. Furthermore, the bottom of the rod and the top

  rigid shell can exert pressure on the instep

  unwanted wedges that cause pain, due to the non-res-

  pect of anatomy and natural movement: of the ankle The possible presence of an inner shoe made of soft material and relatively comfortable in a static position does not solve this problem because it can only partially compensate for the stiffness of the shoe during

  natural flexing movements around the ankle.

  The present invention aims to overcome these disadvantages by restoring the ankle with sufficient freedom of flexion allowing

  It works in better conditions of comfort and better ab-

  sorption of irregularities, bumps and hollows, in skiing,

  which will result in greater flexibility and less fatigue

  build muscles because the equilibrium position can be ensured

  serialized on either side of the shoe by two pivots 8 provided with a head for las to stop in translation in the transverse direction p 2 r relative to the shell 1 and to the bottom of the rod 2,3 which they cross% De rar Gn also known Ent, the pivots 8 are fixed in position relative to the shell 1 either permanently, or after having been adjusted here relative to the latter in the woyenq for example, of a device such as that described in patent application FR 2433311 o These devices allowing a grab held by the foot adapted to its anatomy propai ais the articulation axis 8 does not allow a bending flexibility sufficient around the ankle in the front or rear supports O It there follows painful local prassions, a great fatigue and

  the instep which however remain perfectly maintained.

  Advantageously, the lights 9 are presented under the

  general shape of arcs of a circle turning their concavity upwards.

  The comfort of the wearer in the region of the flexion fold of the front part of the ankle and of the lower tibia can still be improved.

  enhanced by a system of tabs associated with the transverse articulation

which has just been described.

  As already said, a tongue 5 can cover the shell 1 or

  green on the instep and enjoy some play in the longitu-

  dinal with respect to this This tab 5 on which the instep rests will therefore while maintaining it perfectly, be able to

  follow in its movements of small amplitude forwards or backwards.

  Advantageously, this tongue 5 extends above the fold

  bending under the cuff 2 to the upper edge of the shoe.

  Preferably, a notch 10 divides it into two branches 1 l forming

  fork in front of the antero-inferior part of the tibia, so that

  these can spread in the pushes forward and by their elasticity

front or back of the lower leg.

  This upper part Il of the tongue 5 can in turn

  be covered by a half-tab 12 enveloping the front part

  lower leg under the cuff 2 Advantageously this half

  tongue 12 will be articulated on the first 5 around two pivots la-

  terals 13 fixed relative to the latter 11 and above the bending fold to follow the displacements of the upper part 1 l of this first tongue 5 This possibility of flexibility can be further improved by passing each pivot 13 through a light 14 approximately

  vertical or slightly oblique and formed in the half-tongue 12.

  This half-tab 12 can move slightly up or down relative to the pivots 13 while being able to rotate around them by matching the movements of the lower leg.

  painful areas due to unwanted local pressure

born in this region.

  In the case where the shell 1 is not open on the cou-

  at the foot, the tongue 5 would disappear in its front part and its upper part l I could remain and hang on the shell 1 The external half-tongue 12 would then be articulated directly on the

  shell 1 in the same way as it was on the tongue 5.

  From the above it can therefore be seen that the foot, while remaining constantly firmly held both in the rigid shell and in the upper, will still be able to retain its natural flexion movements either for skiing or for walking 9 which must do disappear from serious muscle fatigue and most of the resulting accidents. The invention can be applied to any shoe with a rigid shell

  and stem in one or two pieces It also presents the avarn-

  important step to automatically compensate for swelling and other

  deformations of the shell, which usually result, they also
