Definitions

  • the present invention relates to a rigid-shell sports shoe for gliding apparatus, such as the ski or the skate, comprising a physiological sole particularly adapted to the transmission of the user's efforts to the gliding machine for its effective guidance. It is particularly suitable for implementation via the bottom sole of the ski boots shell.
  • the invention also relates to such a sole as such.
  • a sports shoe for gliding device serves as an interface between the body and the gliding device, this interface being responsible for directing the forces in favorable directions so as to pass on rapidly the muscular tension of the athlete with the gliding apparatus in an effective manner to react to the modifications of situations which arise 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 shell to reach the maximum holding mentioned above.
  • This bearing structure can be considered as a vault with three arches and three support points 1, 2, 3, forming a triangle whose vertices are respectively the heel 1, more precisely the posterior tuberosity of the calcaneus , the head of the first metatarsal 2 and the head of the fifth metatarsal 3.
  • the weight of the body is distributed approximately 50% on the heel, 30% on the first metatarsal and 20% on the fifth metatarsal .
  • the top of the vault is constituted by the astragalus on which rests the tibia, the weight transmitted by the tibia dividing into three main forces directed in the directions of the three points of support 1, 2, 3, these forces being transmitted on the one hand by the heel 1 and on the other hand by the scaphoid and the metatarsals at the anterior points of support inside 2 and outside 3.
  • the three support points 1, 2, 3 of the vault plantar transmit the reactions of the soil, through the ski and the shoe, to the leg and the brain.
  • the document CH688636 proposed a new ski boot solution taking into account the previous remarks concerning the structure of the foot.
  • the solution proposed the addition of rigid elements precisely arranged at the three points of support of the foot 1, 2, 3 for a better direct transmission of the forces of the leg on the gliding board through the foot , guaranteeing that there will be no deformation of the sole under the forces undergone at these points of support.
  • a general object of the present invention is a sports shoe solution for the transmission of the user's efforts to a gliding machine and the guidance of a gliding device by the foot which does not understand the disadvantages of 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 is a sports shoe for gliding apparatus which improves the comfort of the user's foot.
  • the invention is based on a sole of a sports shoe which comprises a layer of rigid material, characterized in that it is linked to the shell of a shoe by a zone of deformable material positioned under the rigid material of the sole, this area being located in the region for receiving the head of at least one of the first or fifth metatarsal foot, and in that it comprises at least one side wing.
  • the invention will be illustrated in the context of a ski boot. However, the same concept could be applied to any other sports shoe that participates in guiding a gliding machine. In addition, the concept of the invention will be illustrated by a modification of the bottom shell sole of the shoe. It could however also be implemented through any other sole of the shoe.
  • the first embodiment of the invention is based on a particular bottom sole shell whose foot receiving portion mainly comprises a layer 11 of relatively rigid material, for example a plastic of a few millimeters d thickness and 60 shD, forming a thicker central rib 12 to fit into the groove 21 of the bottom shell defined by the inner shape of the sole of the shell 15.
  • the sole further comprises zones 13 of deformable material , may be for example a polyurethane foam or any plastic between 25 and 60 shA, arranged on the lateral parts of the foot, more precisely at the anterior points of support 2, 3 of the foot mentioned above.
  • This sole of the bottom of shell further comprises two lateral wings 14 in the continuity of the rigid layer 11, in the same rigid material, which go up to the level of the articulation between the shell 15 and the collar 16 of the shoe, and are attached to the shoe on the same hinge pin 17 passing through two openings 18 made towards the upper end of the flanges 14.
  • FIGS. 3 and 4 A possible form of the zone 13 'of deformable material is illustrated in FIGS. 3 and 4, according to a variant of the first embodiment of the invention.
  • this zone 13' has been represented for the sake of clarity. the description of the invention, but they should normally be hidden by the upper layer 11 which covers it.
  • This form 13 ' is similar to a butterfly whose center of wings corresponds substantially to the two natural support points 2, 3 of the skier's foot.
  • the bottom sole of the shell conforms to the shape of the shell bottom by a central rib 12, present outside the zones 13 'of deformable material, this rib being of rigid material of a shape corresponding to the groove 21 made in the sole of the shell 15.
  • the lateral parts of the sole including those comprising the zone 13 'deformable material conform to the rounded side walls 22 of the shell.
  • FIG. 5 illustrates the straight position in which the skier's entire body is straight and exerts no particularly oriented pressure. This corresponds for example to a situation of descent in a straight line.
  • Figure 6 illustrates a new configuration of the shoe corresponding to a new position of the body of the skier following a flexion of the knees and pressure on the tibia, for the purpose of initiating a turn, for example.
  • the foot Following this flexion of the knees, the foot has a natural tendency to rotate and this position thus moves the weight of the skier laterally to the inside of the foot in this example.
  • This induces a weight transmitted precisely on the first metatarsal 2 of the foot on the bottom sole of the shell as illustrated by the arrow F.
  • This force causes a deformation of the deformable zone 13 of the bottom sole of the shell against the hull portion 22 at the location of this force F, allowing the pivoting of the foot.
  • the latter thus performs a slight rotation around a central axis defined in particular by the rib 12.
  • This deformation of the bottom plate of the shell leads for first effect a movement of the foot and a better location of the body effort precisely on the first metatarsal 2 of the foot that thus also participates by its movement in the shoe to the transmission of the effort to the ski, according to its natural mechanics.
  • the deformable portion 13 reduces the hard point felt on the foot and improves the comfort of the shoe. Similarly, one would observe an equivalent phenomenon in case of rotation of the foot to the outside.
  • the bottom sole of the shell also comprises a layer 19 of deformable material at the heel whose function is only to ensure the comfort of the foot on this fulcrum 1 .
  • a strip 20 in a deformable material for example a polyurethane of hardness less than 60 shD, extends over the entire width of the flanges 14 and divides them into two parts.
  • a deformable material for example a polyurethane of hardness less than 60 shD
  • This band 20 provides a spring effect at the wings 14 between the two lower and upper parts of the wing, which thus participates in the transfer of forces on the rod by regulating the share of traction transmitted on the structure itself.
  • Figures 7 and 8 illustrate two embodiments of the previous embodiment of the invention in which the kinematics is the same, which differ mainly by the smaller height of the wings 14 and their attachment on lower parts of the hull 15 of the shoe.
  • This connection between the wings and the shoe is an essential element of the invention. It allows a correlation between the phenomenon of guidance by the foot and the transmission of the efforts of the leg of the user.
  • FIG. 9 illustrates a second embodiment of the invention in which the two wings 14 are not symmetrical relative to the sole 11, the wing corresponding to the inside of the leg extending higher than the other.
  • the connection between these wings 14 and the upper of the shoe differs from the previous embodiments in that the wings 14 are no longer directly attached to the rod.
  • they fulfill their function of transmitting the forces between the sole and the upper of the shoe by their simple support against the wall of the shoe, the intensity of which varies according to the position of the skier.
  • FIG. 10 illustrates a third embodiment of the invention, in which the bottom sole of the shell comprises two parts 33 extending under the rigid sole 31 from the lateral bearing zones of the foot 2, 3 and up to in contact with the ski, through the sole 21 of the hull 15.
  • the deformation of the bottom sole of the hull has a direct effect on the ski and allows direct transmission of the foot to the ski effort caused by the weight of the skier, without using the hull 15 as an intermediate.
  • the wings 34 are similar to those of the previous embodiment.
  • the invention has been illustrated by a modification of the bottom shell sole of the ski boots but it could be applied according to the same concept via any other sole integrated in the shoe, removably or not. In addition, it could be implemented in an equivalent way by the positioning of a deformable material not belonging to the sole but placed between the rigid sole and the shell, possibly attached to the shell.
  • the solution is a combination of elements that achieve the desired result.
  • the rigid material of the sole is necessary for the transmission of the forces exerted by the body of the skier and the maintenance of the foot in the shoe. This maintenance is improved by the wings of the sole, which also allow through their rise in the direction of the collar of the shoe a better transmission of the efforts of the lower leg to the foot and vice versa.
  • the foot itself has a direct guiding effect on the gliding device due to its slight mobility in the shoe made possible by the deformable material.
  • the rigid material may be a plastic material of hardness at least equal to 60 shD, or any other material of equivalent or greater hardness.
  • the deformable material may be of different types, each of these types participating in the guidance of the ski in a particular way.
  • 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 guide to the ski, and for use in a straight line as the case of a downhill 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 energy for a quick 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.
  • 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.
  • the term "deformable" is therefore used in a very broad sense in this invention, incorporating in particular all the variants mentioned above.
  • plastic materials of hardness less than 60 shD which will have a deformable character compared to the harder rigid material composing the rest of the sole.
  • the common point of all these materials is their possibility of deformation relative to the usual conventional shoes, inducing a primary technical effect consisting of a movement of the foot in the shoe leading to a guide of the ski.
  • the material used for the deformable strip 20 disposed on the flanges 14 of the sole may also vary over a wide range, similar to that described above for the deformable material 13 under the sole.
  • the choices of these two deformable materials will advantageously be coordinated to obtain an optimal complementary combined effect between them.
  • a highly deformable material under the sole may be associated with a highly deformable material on the corresponding wing, to allow maximum pivoting of the sole.
  • the sole may be asymmetrical.
  • the wings can have different lengths, as this has been presented with reference to Figure 9.
  • only one wing can be provided.
  • the deformable material used may be different in nature on each of the anterior points of support of the foot. Indeed, the support positioned inward, called the first metatarsal 2, is directly concerned when making a turn because it supports a significant pressure to retransmit to the ski. It can therefore be envisaged to use an elastic and relatively rigid deformable material under this support. Regarding the second external support 3, unintentional support at this point may lead to a fault of edge leading to a fall. A more absorbent deformable material could therefore be used on this external support.
  • the concept of the invention therefore covers any combination of deformable materials among those defined above, including the extreme cases of implementation of a deformable material in one of the two front supports 2, 3 of the foot.
  • the concept of the invention therefore makes it possible to implement a multitude of different behaviors of the shoe, and its adaptation quite fine to its desired use.
