Definitions

  • the invention relates to a sports shoe sole, according to independent claim 1, and to a series of cross-country ski boots incorporating such a sole, according to independent claim 15. It also relates to a method of manufacturing such a sole, according to independent claim 16.
  • EP 1 803 362 A1 discloses a sole according to the preamble of claim 1.
  • a first object of the present invention consists in proposing a shoe sole which makes it possible to achieve sufficient rigidity, in particular resistance to bending and/or torsion, for use for cross-country skiing.
  • a second object of the present invention is to provide a shoe sole having a minimum weight.
  • a third object of the present invention consists in proposing a shoe sole which makes it possible to achieve satisfactory comfort.
  • a fourth object of the present invention is to provide a shoe sole which can be manufactured at reasonable cost.
  • the shoe sole comprises a first component forming a chassis and at least one second component assembled to the first component, characterized in that the second component comprises a front part extending substantially longitudinally in the front part of the sole.
  • the vertical direction designates the direction from bottom to top, that is to say from the sole of the shoe to the top of the shoe.
  • underside of the sole will designate the lower surface of the sole, visible from the outside of the shoe and intended to come into contact with the ground or a ski
  • the term “overhead of the sole” conversely designating the upper surface of the sole, oriented towards the inside of the shoe.
  • the longitudinal direction designates the direction perpendicular to the vertical direction, oriented from the back to the front of the shoe (and of the sole).
  • the transverse direction is the direction perpendicular to the longitudinal direction in the plane of the sole. The two longitudinal and transverse directions define a horizontal plane, in which the sole of a stationary shoe is substantially placed.
  • the figure 8 and 9 illustrate perspective views from below of a cross-country ski boot sole 20 according to one embodiment of the invention.
  • the sole is composed of two separate main components, assembled.
  • the figures 1 and 2 illustrate the first component 1, forming a frame of the sole.
  • the figures 3 to 7 illustrate the second component 21 of the sole.
  • the figures 1 and 2 thus illustrate a first component 1 forming a frame of a sole 20 according to the embodiment.
  • This frame forms the whole of the sole 20, with the exception of openings 2, 12 in part central intended to receive the second component 21, as will be explained later.
  • This frame 1 extends over the entire length of the sole 20. In particular, it forms the entire outline of the sole 20. Thus, it forms the heel of the sole 20, comprising a few studs 3 according to a conventional geometry. It then comprises a front part forming a support for a bar or connecting pin 4 oriented transversely and allowing the connection with a binding, as standardized.
  • the front part of the frame comprises two lateral parts 7 delimited by a central longitudinal opening 12, which extends towards the central/rear opening 2, which is wider and located further back, approximately in the rear part of the sole.
  • These two side parts 7 each comprise a succession of front studs 5, substantially aligned in the longitudinal direction, and delimited by grooves 6.
  • the front studs 5 and transverse grooves 6 of the two side parts are aligned on either side of the longitudinal central opening 12.
  • the central/rear opening 2 is positioned between the rear studs 3 and the front studs 5.
  • the chassis is advantageously formed in a plastic material, such as for example a polyurethane, or Pebax ® (polyether block amide) with a hardness of between 50 and 70 Shore D. It is preferably made of a single material to reduce costs but it is will not depart from the scope of the invention if it is composed of several materials.
  • the heel area could be made of another material, for example. It is advantageously manufactured by an injection step. It guarantees the comfort of use of the shoe and contributes to the mechanical properties of the sole in flexion, torsion and lateral flexion.
  • this frame may comprise two longitudinal ribs 8 forming a reinforcement, extending on either side of the central/rear opening 2, mainly making it possible to stiffen the sole in torsion.
  • the figures 3 to 7 illustrate a second component 21 of the sole 20, intended for assembly with the first component 1 described above, in particular at its openings 2, 12.
  • This second component 21 has the function of providing the rigidity/flexibility necessary for the entire sole, to achieve good performance when skiing.
  • it is preferably in a different material from that of the frame. It is preferably made of a more rigid material in the context of a "skating" practice, thus limiting the bending of the sole 20, in particular in the front part.
  • “classic” practice it is preferably in a more flexible material or of similar rigidity to that of the frame to create a zone of flexion in the front part of the sole, mainly in the area of the metatarsals.
  • the second component 21 can be made of a plastic material, such as a polyurethane or Pebax® (polyether block amide) with a hardness of between 50 and 70 Shore D.
  • a plastic material such as a polyurethane or Pebax® (polyether block amide) with a hardness of between 50 and 70 Shore D.
  • it can be made of a plastic material filled with fibers or in composite material. Alternatively, it may be all or part of metal.
  • the second component 21 is preferably formed entirely from the same material, for the sake of simplicity, but may as a variant comprise several materials, and achieve rigidity/flexibility properties as sought.
  • the figures 3 and 4 illustrate the second component 21 of the first embodiment which corresponds to a component adapted more particularly for the practice of skating.
  • This second component 21 comprises a rear part 22 of large surface area, presented as a reinforcement plate, intended to occupy the substantially central opening 2 and/or rear of the sole.
  • the second rigid component 21 is intended to occupy a large area of the surface of the finished sole 20, extending over more than half the width of the sole, to fulfill a function of resistance to torsion of the sole.
  • This second component 21 makes it possible to obtain a sole 20, represented by the figure 8 , after association with chassis 1, illustrated by the figures 1 and 2 .
  • the two rear 22 and front 32 parts can be formed by the same part, or by two different parts assembled together, for example by gluing.
  • the second component 21 integrates at least one longitudinal rib 24, to create a reinforced zone.
  • This rib extends at least partially in the front part 32, and preferably approximately over the entire length of this front part 32.
  • This rib has a width of between 5 to 15 mm, preferably 10 mm.
  • This rib is in relief by approximately 1 to 4 mm, but is always recessed from the lower surface of the side studs 5, this central part not coming into contact with the binding or the ski.
  • this same rib also extends continuously in the rear part 22 of the second component 21.
  • the rib 24 is preferably of a non-constant height, measured with respect to the flat surface of the insert , depending on the desired stiffness in this zone.
  • the anterior part of the rib could be of a greater height than the rear part of the rib, and vice versa.
  • the height of rib 24 could be constant over the entire length of the rib.
  • the second component 21 also incorporates a second rib 27 in its rear part 22, in particular visible on the figure 7 , with a height h measured relative to the flat surface of the second component 21, of between 1 and 5 mm, to increase the torsional stiffness in the central/rear part of the sole.
  • other configurations of ribs in the rear part 22 can be chosen without departing from the scope of the invention, in particular in terms of their number, their dimensions, and/or their orientations with respect to the axis longitudinal.
  • the figures 5 and 6 represent a second component 21 according to an alternative embodiment. It differs from the second component 21 described previously in that its front part 32 does not comprise a continuous rib but studs 25. These studs are aligned in the longitudinal direction and are here 5 in number, but their number could however be reduced.
  • the second component 21 makes it possible to obtain a sole 20, represented by the figure 9 , after its association with a chassis 1 as described above, in relation to the figures 1 and 2 .
  • the front part 32 carries studs 25, separated by transverse grooves 26. These studs have a lower surface reaching the same level as the studs of the chassis on the finished sole, this in order to come into contact with the plate of the binding and/or the ski.
  • This area of spikes 25 can extend over a length similar to that of the area covered by the spikes 5, or possibly over a shorter length.
  • the material used for the second component 21 is less rigid than the material used for the first component 1, thus improving the flexing of the sole 20, in particular in the front part and particularly in the area of the metatarsals.
  • the second component 21 and the first component 1 can be of equivalent rigidity (and/or hardness).
  • the rear part 22 of the second component 21, of wider width than the front part 32 can also include reinforcing ribs 24, 27 (visible on the figure 7 ) to increase the torsional rigidity of the sole.
  • a rib 24 can extend in the extension of the series of studs 25.
  • the sole according to this alternative embodiment is preferably intended for traditional or “classic” cross-country skiing.
  • This second component 21, for the two variant embodiments, can be manufactured by any means.
  • it can be manufactured by plastic injection in an embodiment in plastic material.
  • the studs 3, 5, 25 of the two components 1, 21 can be formed at the same time as the component which integrates them, thus forming a monolithic assembly with said component, or be formed separately by a separate step. . In the latter case, this has the advantage of being able to use a material other than that used for the two components described previously, in particular a very flexible material particularly suitable for absorbing shocks, encouraging walking and/or preventing slippage.
  • each component 1, 21 forms the base of the crampons, which is then covered with a flexible, rubber-like and/or non-slip material. It is also possible to use a polyurethane with a hardness of between 40 and 60 Shore D.
  • the manufacturing process can include an additional plastic injection step on the sole obtained by assembling the two components described, to form the coating of stud surface. Furthermore, the coating may extend beyond the surface of the studs to cover all or part of the insert and/or of the frame.
  • the figures 8 to 10 represent the finished sole 20, formed by assembling the two components 1, 21 described above. These two components can be manufactured separately and then assembled by any means, mechanical or not, such as bonding.
  • the second component 21, manufactured beforehand during a first injection into a first specific mold is then placed in a mold for manufacturing the sole, to form the chassis during a second injection into this second mold.
  • the chassis is then attached to the second component during this second injection to form the sole.
  • the second component forms an insert and the sole is obtained by overmolding the first component around and on this insert.
  • the second component forming the insert comprises several through holes 28 arranged on its periphery, in an area which will be covered on its two lower and upper surfaces by the injected material forming the frame, this adding a mechanical interlock of the two components with each other.
  • the frame 1 is molded over the insert (second component 21), and its material passes through the through holes 28 of the insert.
  • a reinforcing piece 40 to carry the connecting pin 4 with a binding, as shown in the figures 11 and 12 .
  • the use of this reinforcement piece guarantees good retention of the connecting pin 4 independently of the choice of materials for the frame or the second component.
  • the reinforcing part 40 has substantially a U or V shape.
  • This reinforcing part is manufactured by injection, independently of the injections making it possible to produce the components of the invention.
  • a rigid plastic material is injected imprisoning the connecting pin 4 at its two ends.
  • the material used can be a polyurethane with a hardness of between 50 and 70 Shore D.
  • the side branches of the pin can be embedded in the side parts 7 of the frame.
  • This reinforcing element 40 carrying the connecting pin 4 is then positioned in the mold for manufacturing the sole at the same time as the second component 21, then the material intended to form the first component 1 is injected into the mold to form the sole 20.
  • This reinforcing piece 40 allows thus to stiffen the sole in this part carrying the connecting pin 4 in order to resist the forces of connection with the ski binding.
  • the figures 8 to 10 therefore represent the sole obtained by assembling the two components 1, 21 described above.
