ICE CLIMBING SHOE

  The present invention relates to a climbing shoe on ice cascade intended for

receive crampons.

  Usually, the shoes intended for such a practice are mountain or climbing shoes intended to receive ice spikes. These shoes have a rigid outer sole, substantially non-deformable, in particular in flexion, and having at the front and at the back gripping surfaces intended to cooperate in a manner known per se with so-called removable ice spikes, which are put in

place before climbing.

  In a shoe of this known type, specially adapted crampons are fitted

  in cavities in the tread.

  The purpose of the present invention is to provide a shoe intended for climbing on

  ice that is as housable as possible and as efficient as possible.

  This object is achieved according to the present invention by the fact that the sports shoe, in particular ice climbing, comprises a rod on which is directly fixed a

  rigid sole, on which the studs are fixed directly.

  One thus obtains a shoe specific to the activity envisaged, and notably lightened, while having the rigidity required for holding crampons and practicing sport, since

  devoid of a traditional sole always heavy bear.

  2 0 Furthermore, the crampons are fixed much closer to the foot, which increases

the effectiveness of the whole.

  In any case, the invention will be better understood and other advantages will be realized.

  evidence with the aid of the description which follows with reference to the appended schematic sin, in

  illustrating by way of nonlimiting examples, several embodiments and in which: 2 5 - Figure 1 is an exploded perspective view of a shoe according to the invention, - Figure 2 is a side view of the shoe in Figure 1, - Figure 3 is a view similar to Figure 2 of a shoe according to another embodiment, - Figure 4 is a cross-sectional view along IV-IV of Figure 1,

  3 0 - figure 5 is a view similar to figure 4 according to a traditional assembly.

  As shown in FIG. 1, the shoe according to the invention consists of a upper 2,

  a rigid sole 10 and studs 20 fixed directly to the rigid sole 10.

  In the case shown in FIGS. 1 and 5, the rod 2 is mounted on a first mounting 3, according to a strobel mounting, that is to say that the first mounting 3 is relatively flexible 3 5 and closes the lower end 2a of the rod 2 by a peripheral seam 4 joining said lower end 2a to the first assembly 3. the rod / first assembly 3 assembly thus assembled is then assembled to the rigid sole 10 by gluing, the adhesive being

  applied between the first mounting 3 and the rigid sole 10.

  The rigid sole 10 is constituted by a plate of composite material, of approximately Smm thickness.

  It has a rigidity of 100 daN and preferably between 80 daN and 120 daN.

  The material used is for example a composite made up of different sheets or materials of glass fbre, carbon or aramid embedded in resins, for example epoxy or polyester. The rigid sole 10 could also be made of a rigid material such as metal, aluminum, etc. The advantage of a composite material construction is that this material offers

  the best compromise between rigidity and comfort.

  Whether the rigid sole 10 is made of composite material or metal, it has inserts

  11 internally threaded capable of receiving screws 12 for fixing the studs 20.

  As shown in the drawing, the studs 20 can be formed of two sets of studs, respectively front 21 and rear 22. They can also be in one piece. The fixing of the crampons 20 on the sole using screws allows a removable mounting thereof, to replace them in the event of deterioration or possibly interposed between the upper

  and the crampon a shoe covering gaiter (not shown in the drawing).

  The studs 20 can also be fixed to the sole 20 by riveting.

  A damping element 15 is also interposed between the upper 2 and the sole 10 at the heel. This light foam damping element also provides a damping function, compensation for the difference in altitude commonly called DH between the heel support 13 and the support of the metatarsals 14 of the foot and therefore reproduces the conventional construction.

shoes.

  In this case, the outer sole 10 is preformed so as to reproduce the difference in height DH between the heel support 13 and the front support 14, and therefore has a profile adapted to the profile.

lower of the rod.

  Similarly, a damping element 16 is provided at the front between the rigid sole 10 and the

  rod 2. I1 could also be eliminated, the damping being carried out only at the heel.

  The embodiment of Figure 3 differs from that of Figures 1 and 2 in that no cushioning element is provided at the heel or at the metatarsals. The rigid sole 10 therefore has in this case a substantially flat profile and the force transmissions.

  from the foot to the crampon or vice versa are more direct.

  Figure 4 illustrates an assembly of the rod different from that shown in Figures 1 and S. namely a so-called traditional assembly. In this case, the rod 2 is mounted on a first of rigid mounting 3, its lower ends 2a being folded down and glued on said first of mounting 3. The advantage of such a construction is that the first of mounting rigid 3 strengthens

still the rigidity of the whole.
