Definitions

  • the present invention relates to a rigid-shell sports shoe for gliding apparatus, such as ski or skate, comprising a structure particularly adapted to the transmission of the user's efforts to the gliding machine for its effective guidance. It also relates to a method of manufacturing such a shoe.
  • a sports shoe for gliding gear serves as an interface between the body and the gliding device, this interface being responsible for directing the forces in favorable directions in order to pass on the tension quickly. athlete's muscle to the gliding device effectively to react to changes in situations that occur during a descent.
  • the ski boots are based on a rigid stem up to the shin, equipped with a comfort liner to thermally isolate the foot and having both the function of reducing the localized pressures that would be painful and fill the spaces formed between the foot and the hull to reach the maximum holding of the foot mentioned above.
  • a comfort liner to thermally isolate the foot and having both the function of reducing the localized pressures that would be painful and fill the spaces formed between the foot and the hull to reach the maximum holding of the foot mentioned above.
  • this solution proposes a better direct transmission efforts of the leg on the gliding board through the foot, ensuring that there will be no deformation of the sole under the forces sustained at these points of support.
  • this solution also retains the mechanics of the traditional approach in which the foot remains motionless and passively transmits the efforts of the body to the gliding board.
  • a general object of the present invention consists of a sports shoe allowing a finer transmission of the user's efforts to a gliding machine, which thus improves the guidance of a gliding machine with respect to the solutions of the prior art. .
  • a first object of the present invention is a sports shoe for gliding gear which takes into account the foot mechanics to improve the performance of the guidance of the gliding machine.
  • a second object of the present invention consists of a sports shoe whose manufacturing process is adapted to a wide range of implementation, according to the desired behavior of the shoe according to the intended use, in order to refine and customize the behavior of the shoe.
  • the invention is based on a sports shoe similar to a traditional shoe but further comprising a mechanical separation of the structure of the two-piece sports shoe by a connecting means having particular mechanical properties and arranged according to a specific geometry on the structure of the shoe so as to be able to allow slight lateral oscillations of a part of the shoe by relative to the other, around an axis of longitudinal rotation parallel to the gliding machine.
  • the result obtained by this function exerted by this connecting element is a guidance of a gliding machine whose traditional practice is enriched by the addition of a slight shift of the weight exerted by the user on the gliding board by exploiting the natural movement of the foot, which improves the passive traditional transmission of the shoe from the efforts of the user to the gliding machine.
  • a sports shoe not forming part of the invention as well as an embodiment of the invention will be described for a ski boot by way of illustration. The same concept could however be implemented on any sports shoe intended for guiding a gliding board such as a roller skate, ice skate ...
  • FIGS. 1 to 12 illustrate a ski boot comprising a rigid sole 1 comprising the front and rear sidewalks 4, 5 for a connection with the jaws of a ski binding, a rigid rod 2 intended to receive the foot of a skier, made of plastic material as a polyurethane hardness 60 shd for example, and a connecting element or intermediate element 3 elastomer between these two low and high parts 1, 2 of the shoe.
  • the sole 1 is made of rigid material so as to withstand the stresses particularly in the front and rear sidewalks 4, 5. It represents the entire floor surface of the shoe and comprises an upper face provided with a central rib 7 defining two substantially equivalent lateral surfaces extending over almost the entire length of the shoe. This upper surface is slightly inclined, sloping from the lowest central point to its higher lateral end 6 at the rear of the shoe, as illustrated in FIG. figure 3 , and is horizontal towards the front of the shoe as shown in figure 4 .
  • a thin connecting member 3 is housed on the upper surface of the sole 1. It comprises a shape that allows it to fully conform to the shape of the sole 1, with front and rear edges 8, 9 according to the inner shape sidewalks 4, 5, a central opening 10 in which the rib 7 of the sole 1 is housed, and a surface of inclined shape from the center towards the lateral end 11 in its rear part and a horizontal surface to follow the surface of the sole 1 in its front part.
  • These two elements 1, 3 are thus fixed to one another over their entire contact surface by a means of type welding, for example obtained by a double injection of compatible plastic materials, or by any other fastening means such as a bonding.
  • the intermediate element 3 is wider than the sole 1 towards the front of the boot and its end 11 projects laterally from the end 6 of the soleplate in order to receive the front part of the shell 12 of the rod 2 of the shoe.
  • the upper part 2 of the boot is the boot upper, comprising a shell 12 and a collar 13 made of rigid plastic material, fastening members 14 for closing and tightening the upper on the leg of a shoe.
  • skier an upper opening 15 in which is housed a comfort liner 16, and comprises in its lower part a horizontal lower portion 17 of small thickness in a rigid material of polyurethane type of 60 shD for example.
  • This lower part 17 has a shape corresponding to the upper surface of the connecting element 3. In its central part, it has a groove 18 on its lower face 17 towards its rear part, in order to cooperate with the rib 7 of the soleplate. 1 which slightly exceeds the upper surface of the intermediate element 3.
  • the result obtained is a ski boot whose final shape, in particular that of the sole uniting the parts 1, 3 and 17, corresponds to the standards of the ski boots. It presents itself with a continuous wall of equivalent shape to the usual shoes. She is able to receive a shell bottom sole then a classic comfort bootie.
  • the advantage of this three-part construction of the shoe is to define two independent low 1 and high 2 parts of the shoe, with relative mobility in lateral rotation relative to each other, as will be detailed thereafter. This mobility is defined by the properties of the intermediate element 3, mainly by the material used and its thickness.
  • the rest of the shoe is in a usual rigid ski boot material to transmit the efforts of the skier to the gliding board.
  • the intermediate element 3 will preferably be in a deformable material that may be for example a polyurethane foam or any plastic hardness between 25 and 60 shA and will have a small thickness, less than or equal to 4 millimeters.
  • the skilled person will choose these parameters to maintain a good compromise between the overall stiffness of the shoe for a traditional transfer of the efforts of the skier to the gliding board and the possibility of a low lateral oscillation of the shoe adding a complement in this guidance of the gliding board.
  • Such a deformable material allows a new behavior of the shoe during a particular position of the body of the skier following knee flexion and pressure in the tibia, for the purpose of initiating a turn, for example. Indeed, following this flexion of the knees, the foot has a natural tendency to rotate so as to move the weight of the skier laterally to one of the two heads of the first or fifth metatarsal foot in the direction of the turn.
  • the structure of the shoe will thus allow the realization of this natural movement of the foot since the upper 2 of the shoe can pivot laterally slightly relative to the sole 1, thanks to the deformation of the intermediate element 3, a lateral surface will be compressed while the opposite lateral surface located on the other side of the central rib 7, which serves as a pivot axis, will be biased in tension.
  • This deformation of the intermediate element 3 causes for first effect a movement of the foot, according to a natural movement explained above, and the rod 2 relative to the sole 1 and therefore to the gliding board, inducing for second effect a better location of the effort of the body precisely at a side portion corresponding to the region of one of Ste 1 or 5 th metatarsus of the foot.
  • the shoe thus allows by its structure and its new mechanics to improve the transmission of the effort to the ski, taking advantage of the natural mechanics of the foot and the lower leg.
  • the deformable material of the intermediate element 3 reduces the hard point felt on the foot and improves the comfort of the shoe. Then, this pivoting of the upper part 2 of the shoe in return promotes bending of the skier's leg.
  • the shoe is no longer a rigid and passive element but has a behavior in harmony with the body of the skier which amplifies the guiding effect of the skier on his ski. It preserves the advantage of the traditional transmission of the efforts of the skier to the ski by the overall rigidity of its structure while adding a refinement of this transmission thanks to its slight deformation allowing a movement of the type lateral oscillation.
  • the rigidities and properties of the different materials used in the different parts of the shoe can vary over a wide range.
  • the rigid material of the lower 1 and high 2 parts of the shoe may be a plastic material of hardness at least equal to 40 shD, or any other material usually used for ski boots.
  • the deformable material of the intermediate element 3 may be of different types, each of these types participating in the guidance of the ski in a particular manner.
  • a deformable energy-absorbing material such as a polyurethane foam can be used.
  • Such a choice will absorb some of the effort transmitted by the skier and will be better for beginners, for a less precise guidance of the ski, and for a use in relative straight line as the case of a descent in competition.
  • the deformable material may also be an elastic material such as a rubber, allowing a portion of the transmitted energy to be restored.
  • an elastic material such as a rubber
  • a hyper elastic material could be used, to allow a dynamic restitution of the energy for a fast and precise change of direction. Any intermediate elastic material could be used.
  • an elastic material of variable characteristics according to its conditions of use can be implemented. For example, a viscoelastic material may be absorbent in case of low speed and elastic loads for high speed stresses. Its use will therefore allow the shoe to behave differently depending on the behavior of the skier.
  • deformable previously used therefore has a very broad meaning in this invention, integrating in particular all the variants mentioned above. It also includes plastic materials of lower hardness than the stiffer hard material composing the rest of the shoe, less than 60 shD, which will have a deformable character compared to the rest of the shoe. The common point of all these materials is their possibility of deformation relative to the usual conventional shoes, inducing a technical effect of mobility by lateral rotation between the two shoe parts that it separates. These materials will thus be chosen in a manner adapted to the desired use of the shoe, according to the wide choice mentioned above.
  • this same ski boot structure can be exploited with a very rigid non-deformable intermediate element, such as a carbon fiber material or a metal for example, for competitive uses in which the skier no longer seeks a comfortable harmony with his shoe but a very high rigidity for a passive transmission and integral efforts it exercises.
  • a very rigid non-deformable intermediate element such as a carbon fiber material or a metal for example
  • the figure 5 illustrates an option that is also compatible with embodiments of the invention, which allows for a given shoe to adjust the mobility of the upper part 2 at a given point.
  • This solution rests for example on an adjusting screw 19 whose head is accessible under the lower face of the lower part 1 of the boot and whose end is positioned in the thickness between the two lower parts 1 and 2 high of the shoe, in an opening within the intermediate element 3.
  • This end of the screw 19 therefore represents a stop for the upper part 2 which limits its possibility of descent in the event of compression of the intermediate element 3.
  • Such a solution can be implemented anywhere in the shoe, but will be especially advantageous at the areas of pivoting of greater amplitude.
  • the solution allows a lateral pivoting of the upper part 2 of the boot under the effort of the skier, this pivoting having the greatest amplitude in the areas of the shoe receiving the heads of the 1st and 5th. th metatarsal of the foot on which distributes most of the weight of the skier.
  • This weight of the skier oscillates between these two lateral points of support at the front of the foot and the shoe has a structure allowing it to react by following more or less this oscillation movement.
  • the presence of the deformable material of the intermediate element 3 at the heel in the first embodiment therefore has for main function the comfort of the foot on this point of support at the heel.
  • Figures 6 to 12 illustrate variants in which the lower part 1 'of the shoe consists of a sole part comprising a front sidewalk 4' and not extending to the rear sidewalk of the shoe which belongs to the upper part 2 'of the shoe .
  • a rigid rod 20 is used to strengthen the attachment of the sole 1 '.
  • the rod 20 is inserted longitudinally through an opening in the rear sidewalk of the shoe and extends to the front of the shoe, positioning itself in an opening provided in the rib 7 'of the lower sole 1' .
  • a binding between the lower 1 'and high 2' parts of the shoe is directly made, which reinforces the fixing by the gluing between the sole 1 'and the interface piece 3' and between the intermediate piece 3 ' and the lower zone 17 'of the upper part 2'.
  • a first sub-variant in relation to Figures 1 to 12 may consist of the removal of the ribs 7, 7 ', the intermediate element then extending over the entire surface of the sole of the shoe to fully separate the lower 1 and high 2 of the shoe.
  • this intermediate element will be provided with an additional function of damping vertical shocks exerted on the shoe, while retaining the possibility of lateral rotation, one side being compressible and the other stretched in tension in the case of a transmission of a force laterally offset by the weight of the skier.
  • a second opposite sub-variant may consist of a wider central rib, however not extending to the two front support points on the skier's foot to allow the implementation of the lateral pivot around this rib.
  • the rib can be made differently, by means of substantially aligned pins, or even two points of support front and rear. Alternatively, the rib can be obtained by a number of substantially aligned screws.
  • the rib may be asymmetrical, offset from the longitudinal axis of symmetry of the shoe, or inclined.
  • the shoe can be obtained by the superposition of physically distinct elements.
  • the shoe can be obtained by methods combining several injections of plastic materials.

  • the different superposed elements are not fixed to each other over their entire contact surface.
  • they will be fixed on at least a portion of the peripheral zone of the shoe, to prevent their spacing and the entry of dust between the layers of the shoe.

  • the connecting element will work in traction on one side and in compression on the other side during lateral rotations of the upper part. 2 relative to the lower part 1.
  • These fixing means can be mechanical means, collages, welds ...
  • the concept can be simply implemented on existing shoes with removable front and rear heelettes.
  • an intermediate element of small thickness can be positioned between the removable heel and the shoe, the assembly being held in position by screws connecting the heel and the rest of the shoe, these screws being positioned at the central portion. of the heel piece to define a connection equivalent to the preceding rib 7, 7 'and to allow the lateral oscillation function of the boot relative to the removable heel pieces.
  • the concept of the invention consists of the separation of the shoe into two parts, a so-called “low” part linked to the gliding board and a so-called “high” part linked to the skier's leg and having a lateral mobility with respect to this lower part considered as fixed, through a connecting zone which consists of a part of the shoe with special mechanical properties.
  • a ski boot is illustrated in which the front portion of the boot can pivot around the support plate 21 of the sole of the boot.
  • an intermediate element 23 is made in the form of two narrow strips of deformable material forming two inverted side U, which extend on the outer surface of the sole of the shoe.
  • These two inverted U-shaped strips consist on the one hand of parallel and transverse strips 26, distributed on either side of the support plate 21 on the lower horizontal surface of the sole of the boot, and on the other hand strips 28 which then go up on the substantially vertical side wall of the sole of the shoe and which meet to form the top of the inverted U.
  • the horizontal parallel strips 26 of the two inverted U-shaped portions of the intermediate element 23 do not meet under the sole but leave a central portion 27 uncut, which plays a role substantially equivalent to that of the rib 7 described above.
  • the movement of the weight of the skier during an initiation of a curve induces an overpressure on a lateral part of the shoe.
  • the U-band undergoing this overpressure will compress at its portion 28 in the vertical plane while the horizontal portion 26 will be stressed in shear.
  • this inverted U-shaped band will allow the upper part of the boot to pivot laterally, the support plate 21 of the sole of the shoe remaining stationary bearing on the gliding board.
  • the rear part of the shoe illustrates another possible implementation of the solution in which the lower part 21 'of the boot fixed on the gliding board comprises a rear part of the sole including the rear sidewalk 25.
  • the intermediate element 23' separates this lower part 21 'of the remainder of the shoe by a band of deformable material which divides the wall in two extending along the wall of the shoe from a point 29 at the level of the sole, bypassing the sidewalk 25 in a point 30 positioned in the wall of the upper of the shoe above this sidewalk and then down symmetrically on the other side of the shoe.
  • This band is interrupted in the central part 27 ', around which the upper part 22 of the boot can pivot relative to the lower rear part 21' thanks to the deformable band 23 ', working in compression on one side and in tension the other.
  • This central part has a function similar to that of rib 7 of the first embodiment.
  • This band 23 ' also extends on the horizontal wall of the sole in a band similar to one of the strips 26 of the front part. Such a band is not shown because masked by a rear heel 31 of the shoe that covers it.
  • the intermediate band may be in a deformable material as explained above or be on the contrary in a very rigid material, depending on the desired behavior of the shoe.

  • This realization illustrates that the concept of "high part” and "low part” must be understood in a very broad sense, since the upper part will tend to follow the movement of the leg of the skier and will thus be equipped with a lateral mobility with respect to the lower part, linked to the gliding board and substantially immobile on this gliding board.
