Definitions

  • the present invention relates to plantar soles for use in an article of footwear between a sole of the article of footwear and the plantar surface of a user's foot.
  • Known soles are generally limited by an upper main surface adapted to be in contact with the plantar surface of the foot, with a lower surface adapted to be in contact with the footwear sole, and with a peripheral contour shaped to engage in the inner contour of the footwear.
  • the insoles generally have a purpose of compensation of size or shape, for a better adaptation of the footwear on the foot of the user.
  • the document DE 35 08 582 A discloses a sole which has, on its upper side, isolated convex elastic zones constituting massage cushions. These massage cushions are placed in the regions of the reflex zones of the foot, to act on these zones.
  • the reflex zones as described are clearly away from the foot support zones, or cover only a small portion of such support zones.
  • the document US 2001/0039746 A1 describes a sole having elastic convex zones constituting massage cushions for improving the venous circulation.
  • the massage cushions as described are not placed specifically in the foot support zones: most are away from the support zones, the others only partially cover certain support zones.
  • the problem proposed by the present invention is to design adaptable means in most footwear, ensuring both effective shock absorption of the foot during use in running or running, and simultaneously ensuring excellent stability of the footwear. foot in the shoe to avoid relative movements of the foot relative to the shoe during walking, running and lateral or rotational movements during changes of direction.
  • the invention results from the observation that it is possible to appreciably improve the comfort and substantially reduce the risks of joint and tendon damage by combining both an effective selective damping of the major zones of support of the foot in the shoe, and a uniform specific and individual lateral of these major areas of foot support which improves the stability of the foot in the shoe to avoid the tendency to loosen and slip of the foot in the shoe during the movements of step, stroke and change of direction.
  • the invention also aims to provide such means which are particularly robust and effective, suitable for use in any type of footwear.
  • the invention provides a footbed for use in an article of footwear between a sole of the footwear and the plantar surface of a foot, the sole comprising the features of claim 1 .
  • the invention determines four support zones in the main surface, corresponding to four major areas of support of the foot during the most frequent use.
  • the main surface bearing areas with stiffness or lower relative hardness comprise an anterior support zone intended to come under the phalangettes of the foot, an intermediate support zone intended to come under the heads of the foot. metatarsals of the foot, a posterior support zone intended to come under the heel of the foot, and an external support zone intended to come under the antero-external part of the calcaneus, below the cuboid and under the fifth metatarsal of the foot.
  • the main surface areas of greater stiffness or relative hardness comprise a peripheral edge completely surrounding the bearing areas of lower stiffness or relative hardness. The stability is thus significantly improved.
  • the main surface areas of greater stiffness or relative hardness all have the same stiffness or higher relative hardness.
  • the stiffness or higher relative hardness can be between 38 and 50 Shore A.
  • the plantar sole according to the invention may consist of a bonding assembly of a first elastomeric material constituting the zones of stiffness or higher relative hardness, and a second material elastomer constituting the support zones with stiffness or lower relative hardness, with the bonding of a top anti-bacterial film and a comfort cloth.
  • a plantar sole according to the invention is limited by an upper main surface 1, a lower main surface 2, and a peripheral contour 3.
  • the lower main surface 2 is adapted to be in contact with a footwear sole.
  • it can be adapted to a footwear whose bearing surface is corrugated in the longitudinal direction to follow the usual general anatomical curvature of the foot, and whose bearing surface is concave in the transverse direction.
  • the peripheral contour 3 is shaped to engage in the inner contour of the article of footwear, and for this purpose has a view from above the usual curvatures of the peripheral contours of the known sole soles.
  • the upper main surface 1 has, at rest, a usual general shape for the soles, and this shape can be variable without departing from the scope of the present invention.
  • the thickness of the sole is slightly variable along a longitudinal plane considered, and varies depending on the transverse position of the longitudinal plane considered. This thickness may be greater in the central area below the sole of the foot, and lower in the end areas. In this case we obtain a compensation effect.
  • the thickness of the sole is variable along the same transverse plane considered, and varies depending on the transverse plane considered.
  • the median longitudinal plane XX of the sole is considered to be the longitudinal plane AA situated away from the plane XX by a distance of Approximately 20 mm towards the inner edge of the sole, the longitudinal plane BB situated away from the plane XX by a distance of approximately 10 mm towards the outer edge of the sole, and the longitudinal plane CC situated away from the plane XX at a distance of approximately 33 mm towards the outer edge of the sole.
  • the thickness of the sole at the anterior end may be of the order of 6 mm, while its thickness in the median zone may be of the order of 11 mm and its thickness at the posterior end may be of the order 9 mm.
  • the anterior thickness is of the order of 6 mm
  • the central thickness is of the order of 12 mm
  • the posterior thickness is of the order of 8 mm.
  • the anterior thickness is of the order of 6 mm
  • the central thickness is of the order of 10 mm
  • the posterior thickness is of the order of 8 mm.
  • the thicknesses are given by way of illustrative example, and are liable to variations depending in particular on the depreciation to be achieved. It will thus be possible to choose increased thicknesses to increase the damping properties, or conversely.
  • the plane DD is approximately 5.5 cm from the point
  • the plane EE is about 11 cm from the point
  • the plane FF is 16 About 5 cm from the tip
  • the GG plane is about 22 cm from the tip.
  • the thickness of the sole is reduced to zero along the inner edge and along the outer edge.
  • the central thickness varies according to the transverse plane considered.
  • the lower main surface 2 is convex, while the upper main surface 1 is concave. So in the DD plane shown on the figure 5 , the concavity of the upper main surface 1 forms a hollow of about 5 mm, as well as in the transverse plane EE illustrated on the figure 6 . In the transverse plane GG illustrated on the figure 8 , the hollow is about 12 mm.
  • the length of the sole 42 is 27.5 cm. Its width is variable depending on the transverse plane considered: the width is about 8.5 cm in the transverse plane DD, about 9.5 cm in the EE plane, about 7.5 cm in the plane FF and about 7 cm in the GG plane.
  • the soleplate in the embodiment illustrated in the Figures 2 to 4 , comprises a base structure 5 on which is fixed an upper film 4 itself preferably covered with a comfort cloth 4a constituting the upper surface 1 and adapted for contact with the skin of the foot.
  • the upper film 4 may advantageously be of anti-bacterial material, with a thickness of the order of 1 mm. It is thus possible to choose, for the basic structure 5, a different material, adapted to the desired effects, and which one does not have to make sure of the compatibility with the contact of the foot.
  • the sole of the invention is intended to cooperate with the foot in a particular way, to ensure the functions of effective shock absorption of the foot and foot stability in the shoe during walking, running, rotation or change of direction.
  • the sole cooperates essentially with the major zones of support of the foot, which are illustrated on the figure 9 .
  • FIG. 9 in plan view, there is shown the horizontal projection of the skeleton 20 of the foot.
  • the metatarsal heads 26, 27, 28, 29 and 30 the calcaneus 31 which has a posterior portion 31a constituting the heel and an antero-external portion 31b, a outer part of the cuboid 32, and finally the fifth metatarsal 33.
  • the set of phalangettes 21-25 is a first major foot support zone.
  • the metatarsal heads 26-30 constitute a second major zone of support of the foot.
  • the posterior portion 31a of the calcaneus, or heel, constitutes a third major zone of support of the foot, together with the anterolateral part 31b of the calcaneus, with the cuboid 32 and with the body of the fifth metatarsal 33.
  • the sole according to the invention comprises distinct zones, and these zones have distinct mechanical properties.
  • an anterior support zone 6 intended to come under the phalangettes 21-25 of the foot of the user
  • an intermediate support zone 7 intended to come under the metatarsal heads 26-30 of the user's foot
  • a posterior support zone 8 intended to come under the heel of the foot of the user
  • an outer bearing zone 9 intended to come under the antero-external portion of the calcaneus 31b, below the cuboid 32 and under the fifth metatarsal 33 of the user's foot.
  • the anterior support zone 6 is limited by a continuous contour which borders the first major support zone of the foot formed by the phalangettes 21-25.
  • the contour of the anterior support zone 6 is relatively close to the contour of the phalangettes 21-25, following this contour in a relatively faithful manner as illustrated in FIG. figure 9 .
  • the intermediate support zone 7 is bounded by a contour which borders the second major foot support zone consisting of the metatarsal heads 26-30. This contour of the intermediate support zone 7 follows fairly closely the contour of the metatarsal heads 26-30, as illustrated in FIG. figure 9 .
  • the posterior support zone 8 is also limited by a contour which borders the major zone of support of the foot constituted by the heel 31a, as seen on the figure 9 .
  • the external bearing zone 9 is bounded by a contour which closely borders the major zone of support of the foot formed by the antero-external part of the calcaneus 31b, the cuboid 32 and the fifth metatarsal 33, as illustrated in FIG. the figure 9 .
  • bearing zones 6, 7, 8 and 9 thus defined constitute, in the main surface 1, main surface areas having a lower stiffness or relative hardness.
  • the remainder of the sole is main surface areas of greater stiffness or relative hardness.
  • Areas of greater stiffness or relative hardness include a peripheral rim 10 which completely surrounds the lower or lower relative hardness bearing zones 6, 7, 8 and 9. Having a higher stiffness or relative hardness, there is also a plantar zone 11. , an intermediate transverse zone 12, and an anterior end zone 13.
  • the main surface bearing areas with stiffness or lower relative hardness namely the anterior support zone 6, the intermediate support zone 7, the support zone posterior 8 and the outer support zone 9, receive the major zones of support of the foot, and therefore suffer the most important mechanical forces of the foot. They deform elastically under the action of the foot. Thanks to the fact that their stiffness or relative hardness is lower, the stress deformation is increased of the anterior support zones 6, 7 intermediate, 8 posterior and 9 external, promoting a certain local depression of the foot in these areas, while amplifying the effects of peripheral and intermediate support by the other adjacent plantar areas having greater stiffness or relative hardness and which deform little. This results in both good shock absorption due to the deformation of the support zones with stiffness or lower relative hardness, and a better stability of the foot in the shoe due to the least deformation of adjacent areas of main surface stiffness or higher relative hardness.
  • the stiffness or hardness of the support zones with stiffness or lower relative hardness can be between 20 and 35 Shore A.
  • the stiffness or hardness of the zones with stiffness or higher relative hardness can be between 38 and 50 Shore A, with advantageously a hardness difference of at least 10 Shore A between the higher relative hardness and the lower relative hardness, and preferably with a hardness difference of at least 15 Shore A.
  • the bearing zones 6, 7, 8 and 9 with a stiffness or a lower relative hardness can be determined with curvilinear contours as shown in FIGS. figures 1 and 9 , the anterior support zone 6 consisting of the association of five oval zones each corresponding to one of the phalangettes, the intermediate support zone 7 also consisting of five oval zones each corresponding to one of the metatarsals of the foot, the posterior bearing zone 8 being of oval or circular shape adapted to the shape of the heel of the foot of the user, and the external bearing zone 9 having a width which is gradually reduced from the posterior zone 8 to the portion of the intermediate support zone 7 corresponding to the head of the fifth metatarsal.
  • bearing zones 6-9 with stiffness or reduced hardness considering that they are written in two polygons defined as follows.
  • the anterior support zone 6 is circumscribed in an abcdefghi polygon in which the origin point a is about 1.6 cm behind the edge of the anterior sole crown and at about 1.1 cm. from the median plane XX to the inner edge of the sole; the sides of the polygon are marked by the corresponding vectors given by their length and by their angle counted in the trigonometric direction from the median longitudinal axis XX considered from the back to the front of the plantar sole seen from above: ab (2 , 6 cm, 240 °), bc (2.6 cm, 180 °), cd (0.9 cm, 120 °), (1.9 cm, 50 °), ef (6.3 cm, 120 °) (2.5 cm, 0 °), gh (5 cm, 310 °), hi (1.6 cm, 270 °), ia (0.8 cm, 0 °).
