Definitions

  • the present invention relates to a shoe intended for sports requiring a movement of the foot, such as for example snowshoeing, cross-country skiing, classic or skateboarding style, telemark skiing and hiking, and / or sliding sports such as snowboarding, ice skating and roller skating, namely sports requiring good transmission of the forces exerted by the foot for better grip, edge grip.
  • a shoe intended for the abovementioned sports must satisfy different requirements and incompatible, which at first sight cannot be achieved without harming at least one of the aspects above.
  • the present invention therefore aims to provide a shoe of improved design which remedies to the disadvantages encountered in the prior art and which reconciles conflicting requirements, to improve the behavior heel while allowing the natural course of the foot, and being simple and inexpensive construction.
  • the central idea of the present invention is to improve the holding of the heel of the foot by providing, at this level, a buttress, which is rigid and substantially non-flexible. It is then the stiffness of the buttress which allows at the same time, satisfactory heel hold and transmission of forces. Furthermore, this construction allows a flexibility of the outer sole in the so-called metatarsophalangeal area and a more natural course of the foot.
  • the rigid buttress extends over at least one side of the shoe substantially up to the so-called metatarsophalangeal flexion zone. It results from the strengthening of the rear part of the shoe, satisfactory transmission of forces from the user's leg to the front part of the foot, which is in permanent contact with the ground or the sliding support.
  • the rigid buttress and essentially the rear part of the base of the foot surrounds the heel like a shell.
  • This construction also allows better transmission of forces, especially in transverse direction, thanks to the reinforcement and the shell shape of the rear part of the shoe, while retaining flexibility of the shoe in the metatarsophalangeal area.
  • Said constructions allow better control of the ski by holding the heel and at the same time a gain general energy and direct transmission of forces by canceling parasitic deformations of the sole and the shoe, which parasitic deformations are useless for propulsion by typical movements of the above sports.
  • FIGS. 1 and 2 is shown a shoe 1 intended for the practice of cross-country skiing, particularly for the skateboard style.
  • the present invention also applies to all sports requiring a unfolding of the foot, such as snowshoeing, cross-country skiing, telemark skiing and hiking, and / or board sports such as snowboarding, ice skating, roller skating, ... etc.
  • the following description is made with reference to a ski boot background.
  • the shoe 1 shown comprises, in a known manner, a upper 2, an outer sole 5 and an articulated collar 8, which is fixed to the rod via a hinge pin 7.
  • a shoe upper for cross-country skiing is well known in the art and will not be explained in detail in the description.
  • the shoe 1 shown in Figures 1 and 2 is provided with a first rear buttress 13, in a material which is flexible enough to allow attachment by stitching of this flexible buttress 13 on the rod 2.
  • the shoe 1 also has a second buttress 3, which is more rigid as the flexible buttress 13, and is in fact substantially non-flexible.
  • This rigid buttress 3 surrounds the heel 11 of the shoe 1 by two walls, respectively lateral 9 and medial 10, and by a rear wall at the heel 11.
  • lateral wall respectively median, is meant each of the walls of said buttress disposed respectively towards the outside and towards the inside of the foot or shoe.
  • the rigid buttress extends forward substantially up to zone 4 of flexion known as metatarsophalangeal.
  • the reinforcement of the shoe 1 via the rigid buttress 3 is therefore limited to a zone between the heel 11 and said zone 4 of metatarsophalangeal flexion.
  • the foot of the user is therefore well held on the side of the heel 11, while keeping the shoe 1 flexible in the metatarsophalangeal flexion zone 4, which allows an almost natural unfolding of the foot.
  • the rigid buttress 3 has a maximum height which does not exceed that of the region located substantially below the ankle area 6, and is notably lower than the level of said zoned.
  • the rigid buttress 3 rises substantially to the level of the zone of articulation of the ankle and comprises the axis of articulation 7 of the articulated collar 8.
  • the maximum height of the buttress 3 is on the contrary lower than the level of the hinge pin 7 which is therefore fixed only on the first flexible buttress 13, which allows more freedom in transverse direction at the level of the collar because of the greater flexibility of the material.
  • the maximum height of the buttress 3 is chosen so that the movement natural ankle 6 is not hindered.
  • each of the walls 9, 10 decreases in height going towards the front of the buttress 2.
  • each wall 9, 10 joins the edge 21 upper of the outer sole 3.
  • the side wall 9 decreases in a substantially continuous manner at an angle of approximately 45 ° with the upper edge 21 of the outsole.
  • the medial wall 10 can have the same shape.
  • the side wall 9, as well as the medial wall 10 decreases also towards the rear, heel zone 11, for better comfort of the foot.
  • the buttress 2 can form a stop 22 for the support of an elastic loop 14 which surrounds the rear of the ankle 6 in the manner of a spur which provides an elastic return to the collar.
  • This loop 14 is also known and does not constitute an essential element of the present invention. It is for this reason that the loop 14 will not be described in detail.
  • the buttress 3 which can make it impossible to fix the buttress 3 rigid directly on the fabric and / or leather of the upper 2, it may be advantageous to fix the buttress 3 rigid, for example by gluing and / or riveting, on the flexible buttress 13, which has a sufficient flexibility allowing its connection, for example by gluing, stitching and / or riveting on the rod 2.
  • the flexible buttress 13 also allows a certain padding of the rigid buttress 3, which avoids local pressures on the user's foot.
  • the rigid buttress 3 covers the flexible buttress 13 only partially, leaving uncovered an edge 23, which extends at least over the upper edge 24 of the side wall of the buttress 3 rigid, so as to facilitate its fixing or connection to the rod.
  • the preferred materials of the rigid buttress 3 are plastics which can be reinforced with fibers, for example glass or carbon, and metallic materials. Of in any case, all the materials are adapted, essentially guaranteeing almost non flexibility of the stiff buttress 3.
  • the preferred stiffness of the rigid buttress is between 260 MPa (Mega Pascal) which corresponds to the Modulus of elasticity Pebax 6333, and 200 GPa (Giga Pascal) this which corresponds to the Modulus of elasticity of a glass fiber + carbon composite.
  • the outer sole according to the embodiment shown in Figure 2 consists in two parts, a front part 15 and a rear part 16.
  • the front part 15 extends essentially from the front end 24 of shoe 1 to zone 4 of metatarsophalangeal flexion.
  • This front part is flexible enough to allow almost bending natural in said zone 4 of flexion.
  • the rear part 16 of the external sole and the rigid buttress 3 form a one-piece assembly and preferably single material.
  • This construction has advantages with regard to the mounting the rear part 16 of the sole and the rigid buttress 3 in one piece on the rod 2, the tightness of the rear lower part of the shoe 1, particularly in the area which traditionally represents the connection between the outer sole and the buttress, and also in with regard to a further improved reinforcement, compared to the embodiment described in reference to FIG. 1, of the rear part and the heel of shoe 2.
  • the rigid buttress 3 shown in FIG. 3 has the shape of a shell of cross section in "U” shaped and completely surrounding the heel, namely laterally, at the back as well as below, and at a maximum height well below the level of the ankle area 6.
  • the height preferred is between about 2 cm and 4 cm.
  • the embodiment according to FIG. 2, namely the monobloc construction of the rear part of the outer sole with the rigid buttress 3, is symbolized by dotted lines.
  • the rigid buttress 3 shown in FIG. 3 completely covers the base of the foot.
  • the buttress 3 might as well cover the base portion of the foot only partially, for example by forming a hollow or one or more recesses in the base part 17 of the rigid buttress 3.
  • the construction of the rigid buttress 3 according to the example shown in Figure 3 allows an entourage of the heel and the rear part of the base of the foot in the manner of a shell.
  • the lateral wall 9 and / or the medial wall 10 of the buttress 3 rigid may be provided with recesses 18, which allows a reduction in the weight of the buttress 3 rigid while keeping its rigidity.
  • the rigid buttress 3 without bottom 17 and provided with flanges 19 extends from the lower edges respectively of the side wall 9 and of the wall 10 medial, horizontally inward.
  • These transverse flanges 19 serve for fixing the buttress by intercalation between a first assembly of the rod 2 and the outer sole.
  • these transverse flanges 19 participate in the stiffening of the rigid buttress 3, in particular in torsion.
  • these transverse flanges 19 can be provided fairly wide so that that they almost meet leaving only one gap between them.
  • the side wall 9 of the rigid buttress 3, in the example shown in the figures, can extend further in the longitudinal direction than the medial wall, respecting the orientation of the natural flexion line in the metatarsophalangeal zone 4, which forms an acute angle with the axis longitudinal of a foot.
