  • Each groove may have a width substantially equal to the width of the machine.
  • the embodiments of the invention described herein relate more specifically to shoes for cross-country skiing, ski touring, telemark or snowshoeing.
  • the invention applies to other fields, such as for example the ice skate or the wheel skate.
  • FIG 3A It has been shown, in figure 3A , a first embodiment of the invention.
  • the rod 13 extends in length from a rear end or heel 14 to a front end or tip 15, and in width between a lateral side 16 and a medial side 17. It comprises a lower portion 20, provided to surround the foot, and possibly an upper portion 21, provided to surround the ankle.
  • the stem may only include the lower portion.
  • the rod 13 may be brought on or in a part called base 200, which has a certain longitudinal flexibility along a transverse axis of the shoe or liner.
  • the base 200 is a flexion blade.
  • this base 200 When assembled with the stem, as shown in figure 3B , this base 200 also extends in length, from the heel 14 to the tip 15, and in width between the lateral side 16 and the medial side 17.
  • This base is monobloc, or in one piece, without additional means forming articulation. Its flexibility allows it to simply adapt to the movements of a user.
  • rod 13 and the base 200 can be assembled to one another, but removably, so that it is possible to exchange the base 200 for another base or blade, or, keeping the same blade, to change the rod 13.
  • the rod 13 comes to rest on the upper face 219 of the blade 200.
  • Reference 210 designates a collar provided with a strap 211 for holding the shoe or the boot.
  • This strap can be opened or closed using means such as, for example, self-gripping surfaces.
  • the blade 200 can be provided with two walls, substantially vertical, 201 (side wall), 203 (medial wall), which will allow to maintain the rear part of the rod 13 and, more particularly, to block a possible torsion of the foot.
  • These two vertical walls can be unassembled or, conversely, be extended, behind, by a part (rear buttress) which joins the rear parts of the walls and which stops the shoe backwards substantially following the shape of the part back of the stem.
  • the buttress is here an external part of the shoe.
  • the walls 201, 203 can extend, in the longitudinal direction of the foot, along a length L, which can reach for example 70% or 75% of the length of the shoe or liner or the total length of the blade 200, which corresponds substantially to the position of the metatarsals.
  • two orifices 202, 204 allow to introduce hinge means such as rivets, or screws, which can cooperate with corresponding openings of the shoe and the corresponding holes of the collar 210 to maintain the assembly or to contribute to the maintenance of the assembly.
  • a holding strap 211 ' may also be present in front of the blade; this strap can be opened or closed by means such as, for example, self-gripping surfaces.
  • the rod can also be held in, or on, the blade by gluing, screwing or riveting.
  • this removable base can have other forms.
  • the base does not have walls 201, 203, or buttresses, and therefore forms a surface plate that is substantially flat, or that extends in two dimensions, and that is intended to be fixed, also removably, against a base of a shoe or against a bootie. It can therefore be flat, the holding with the rod being for example ensured by screwing or riveting.
  • FIG 3C An example of this achievement is illustrated in figure 3C on which is recognized the plane flexible blade 200a. On this flexible blade, it is possible to fix removably elements 250, 251 of a shoe, wherein, in addition, a shoe 252 may be introduced.
  • the means 210 are similar to those already illustrated on the figure 3A . As can be understood from this figure, one can position on the blade 200a one or more elements, the assembly to obtain a very great modularity.
  • the flexible blade 200b can be part of a shell, which can be semi-indented.
  • the lateral parts 201, 203 of the structure of the figure 3A are extended forward, to cover at least the front portion of the lower portion 20 of a boot (not shown in this figure), the assembly can therefore receive the latter.
  • fixing elements 211, 211 ', 212, of the type of those described above in connection with the figure 3B can be expected (they are not represented on the 3D figure ).
  • the presence of the shell, above the flat part of the blade does not modify the flexion of the latter.
  • the role of this blade is, from the point of view of the flexion of the foot, the same as in the case of Figures 3A-3C . It is observed that the shell is here made of several assembled elements but that, alternatively, it could be a single piece.
  • Means that will allow to achieve a contact interface with a ski or racket may include a part, two parts, or more.
  • a fastening element 25 designed to cooperate with the retaining device 3 (shown in FIG. figure 1 ), in particular the locking mechanism 5, itself intended to be subject to a ski 2, and optionally with an elastic return mechanism 6.
  • the ski implement such a structure.
  • the retaining device 3 comprises a base 4, which carries a reversible locking mechanism 5, possibly an elastic return mechanism 6, and, in the example illustrated in FIG. figure 1 a longitudinal guide edge 7; the locking mechanism 5, the possible return mechanism 6 and the guide edge 7 can be secured to the base 4.
  • a single piece intended to be applied against the base such a piece is represented in figure 4 .
  • the holding means of the two parts 25, 140 relative to the base 200 are interconnected by a flexion blade 120, which will have a certain flexibility to accompany the movement of the user.
  • This set is compatible with a method of attachment to a position on the blade, or two or more discrete positions.
  • This blade is for example a metal material and / or composite and / or plastic and / or comprising plant fibers.
  • the connecting element 120 has an extension, towards the front, which is limited so as not to interfere with the strings 26, 27 of attachment intended to cooperate with the retaining device 3.
  • the base 200 like the blade 120, has a certain longitudinal flexibility along a transverse axis of the shoe or liner. It can be folded to accompany the movements of the foot. It may be necessary to adapt this flexibility. This can be done by changing the first blade or the first base and choose a second blade or a second base with another flexibility (stiffer or more flexible than the first). But we can also provide a base adaptable flexibility.
  • reinforcing means such as inserts or rods, which can be introduced into orifices extending longitudinally in the base or blade, as shown in FIG. Figure 5A , on which we see a bending plate 200, and two orifices 220, 221 which allow to slide reinforcing rods 222, 223 in cylindrical areas, made in the base or blade itself.
  • These cylindrical zones are in the extension of the openings 220, 221.
  • the cylindrical zones may be oriented longitudinally, or form with the longitudinal direction Lo of the shoe an angle ⁇ between 0 and 40 °.
  • openings 220 ', 221' may be made on the rear face, as illustrated in FIG. Figure 5B .
  • an opening 224 front or rear face, accommodates a reinforcing element 225 in the form of a plate, for example rectangular, as illustrated in FIG. Figure 5C .
  • a reinforcing element may be a plate, possibly perforated, and intended to be pressed against the upper or lower face of the flexion blade, for example on the zone on which the front part or the rear part of the means are to be fixed or between these two areas.
  • These reinforcing means may be adapted to such a blade, that it is provided in combination with removable elements 25, 140, or with any other means of connection with the machine, for example the ski.
  • Both the connecting means which connect the fastening element 25 to the blade 200, 200a, 200b, as the removable heel, will allow an adaptation of the shoe to any type of ski.
  • the bending base comprises a buttress 241, which is a rear part, a tip 242, which is a front part, and a bridge 243 which connects the buttress 241 to the end 242 by any appropriate means. Screws may be suitable, but other means are possible.
  • the buttress 241 is secured to the bridge 243 reversibly.
  • the tip 242 is secured to the bridge 243 reversibly.
  • the bridge 243 comprises a single plate 244.
  • the bridge 243 comprises several pieces 244, 245.
  • the front and back elements to be fixed on the outer surface of the base are compatible with the NNN® family or the SNS® family.
  • the invention also relates to other restraints or other types of equipment.
  • n parallel edges (n> 2).
  • the attachment means comprise one or two son. But, as already stated, other types of attachment means can be implemented.
  • the positioning, respectively of the front part (hooking element) or the rear part (heel) of the adaptation means has a longitudinal extension that can go up to 30% or 35% or 40%. % of the length of the blade, respectively measured from the front or rear end thereof.
  • the invention is made from materials and according to implementation techniques known to those skilled in the art.
  • the front and rear portions of the adaptation means are made with a number (2 to 4) of molds reduced compared to the number (8 to 15) of molds used to make the shoe soles currently known. From the economic point of view, the advantage is considerable, since, to achieve each mold, it takes an investment of between 10 and 40 K €.
  • the base or flexion blade, for a footwear element provided for the exercise of a physical activity using a machine sliding or rolling, in which the heel is free during the movement of the foot, is characterized in that said base comprises means for fixing said footwear removably with respect to this base or blade, which has flexibility in a direction of extension of the foot and means for fixing, against the front part, in the extension direction of the foot, this base, also removably, at least one attachment element to said gear.
