Definitions

  • the present invention relates to a sole stabilizer for a shoe.
  • the invention further relates to a shank with an integrated sole stabilizer and a shoe with a sole stabilizer.
  • Flexibility of shoes and requirements to such flexibility can vary according to the actual type of shoe and more specifically the environment in which the shoe is to be used. E.g. is it a shoe for use when trekking or for use when playing golf. It is of interest to have shoes where the flexibility properties are quite specific according to the actual environment in which the shoe is intended to be used.
  • a sole stabilizer for integrating in a sole or a midsole of a shoe, wherein said sole stabilizer extends in at least a subpart of the sole area and wherein said sole stabilizer comprises multiple elongated elements extending towards a side of a shoe in a substantially transverse direction of the shoe.
  • the stiffness of the shoe can be changed in a transverse direction, without changing the flexibility of the shoe in its longitudinal direction.
  • the sole stabilizer increases the stiffness of the shoe in the transverse direction.
  • the elongated elements will not have to be bent and therefore flexibility in the longitudinal direction is not changed.
  • the transverse direction is the direction transverse the flex direction of the foot and shoe.
  • the longitudinal direction therefore also corresponds to the flex direction of the foot and the transverse direction corresponds to the width of the foot.
  • a longitudinal direction of the sole stabilizer and a transverse direction of the sole stabilizer these directions are to be interpreted corresponding to directions as defined above.
  • the longitudinal direction is also the flex direction of the sole stabilizer and thereby the flex direction of the shoe and foot wearing the shoe.
  • the stiff transverse direction is the direction transverse the flex direction, corresponding to the width of the sole stabilizer and thereby the width of the shoe and the foot wearing the shoe.
  • the shoe When walking using a shoe with a sole stabilizer according to the present invention, the shoe will maintain the flexibility of the sole material in the flex direction, whereas the sole stabilizer and elongated elements ensures due to their stiffness that the sole material combined with the sole stabilizer are stiff at a direction transverse the flex direction.
  • a number of factors influences the transverse stiffness obtained by adding a sole stabilizer and these factors are:
  • the sole stabilizer comprises subparts of elongated elements and covers an area of a sole and is used together with a sole.
  • the sole stabilizer changes the flex properties of at least sub parts of the sole in a direction transverse to the longitudinal direction or to the flex direction of the sole.
  • said sole stabilizer is dimensioned for extending the entire sole area.
  • a sole stabilizer influences the flexibility of the entire sole and the design of the sole stabilizer affects the entire shoe.
  • a sole stabilizer could be shaped having a contour and covering an area similar to a sole and where the entire area of the sole stabilizer is comprised of elongated elements connected e.g. extending from a centre element or connected at a centre line or at the sides.
  • the multiple elongated elements are positioned in at least one subarea of said sole stabilizer.
  • the sole stabilizer covering the entire sole area could only at specific subparts comprise areas with elongated elements, whereas the remaining part is solid or have another structure.
  • the sole stabilizer is used for changing the sole flexibility differently at specific areas. Thereby, it is only in specific areas the transverse stiffness is increased, e.g. in the side areas or the forefoot area.
  • the entire sole stabilizer is constituted by multiple elongated elements.
  • a sole stabilizer can then be modified afterwards by connected elongated elements to the sole surface and/or by interconnecting a number of neighbouring elongated elements.
  • standard sole stabilizers can be produced, and these standard elements can then afterwards be modified according the properties of interest in the type of shoe where the stabilizer is to be used.
  • the elongated elements are integrated with a shank.
  • shank and the sole stabilizer can be produced as one unit, reducing production cost of these elements.
  • a substantial part of said elongated elements extends to the outer periphery of the shoe and wherein the endpoints of the elongated elements are connected with plate elements being substantially perpendicular to the elongated elements.
  • the plate elements introduce an edge surface to which material can be connected e.g. by gluing, whereby e.g. leather can be used for decorating the sides of the sole.
  • the sole stabilizer is made from material stiffer than the material of the sole.
  • the elongated elements of the sole stabilizer further increase transverse stiffness of the sole.
  • the distance between neighbouring elongated elements are lower than 10 mm.
  • the elongated elements are solely positioned at the front subpart of the shoe. Thereby flexibility in the flex direction of the shoe in which the sole stabilizer is maintained, whereas transversal stiffness is increased.
  • the present invention further relates to a sole for a shoe comprising a sole stabilizer according to the above and a shoe comprising a sole stabilizer according to the above.
  • Fig. 1A, 1B and 1C illustrate a sole stabilizer 101 according to the present invention integrated with a shank 105.
  • the sole stabilizer is shaped similar to a sole for supporting a foot wearing a shoe and the stabilizer comprises multiple elongated elements 103 extending at the edge of the stabilizer as well as in the middle of the front part.
  • the elongated element has a thickness of 3 mm and a width of 2 mm. This is just one example of dimensions used with a sole stabilizer material having a specific stiffness, where similar results with another material being less stiff, would require larger dimensions.
  • the elongated elements extend substantially in a transverse direction (transverse direction relative to sole is marked by arrow B, longitudinal direction relative to sole is marked by arrow A).
  • longitudinal direction A is also similar to the flex direction of the shoe when walking)
  • the elongated elements will also extend in the transverse direction of the shoe wherein the sole stabilizer is mounted.
  • the endpoints of each elongated element are connected with plate elements 107.
  • the purpose of these plate elements is to obtain a surface for connecting a cover material at the edge of the shoe, e.g. leather material.
  • the size of the plate elements changes along the side surface, this is due to design requirements, where typically the shoe tip is required to be thin and therefore the plate elements need to be smaller at the tip.
  • the elongated elements at the tip and at the heel are not extending in the transverse direction, but are still there to support plate elements 107 around the entire shoe.
  • a shank has been integrated for further supporting the foot and for giving the shoe its inner structure.
  • the shank and the elongated elements are made from the same material, which will be stiffer than the material used for the remaining sole. Further the elongated elements are extending from the shank and the entire sole stabilizer could e.g. be produced by a molding.
  • sole stabilizer is not integrated with a shank, instead the shank and sole stabilizer is two separate elements.
  • Fig. 2A-D illustrate the sole stabilizer 201 being mounted in a shoe and more specifically where the sole stabilizer is mounted between the upper shoe and the sole.
  • the parts comprising the sole stabilizer 201, the upper part 203 and the sole 205 are shown being separate.
  • the sole stabilizer 201 has been connected to the upper part 203 of the shoe and in figure 2D also the sole 205 has been connected.
  • a production process could be to position the sole stabilizer in a mold, and then inject the sole material into the mold to shape the sole. The process is similar to injection molding without a sole, only difference is that the sole stabilizer is positioned in the mold before injecting.
  • the sole stabilizer could in one embodiment be inserted as the only element (e.g. with or without an integrated shank or the sole stabilizer and the shank could be inserted as separate elements before injecting.
  • the sole stabilizer is typically not solid whereby the injected material can float through the sole stabilizer e.g. through the spaces between the elongated elements and/or through holes made in other parts of the sole stabilizer. Thereby injected materiel is present on both sides of the stabilizer and thereby the stabilizer is completely integrated in the sole material after hardening.
  • the sole stabilizer comprises plate elements along its edge
  • these elements are typically not integrated inside the sole, but extend from the side of the sole and are used for forming an edge around the shoe adapted for adding an edge cover material.
  • Fig. 3 illustrates the sole stabilizer positioned in a shoe in a cut, whereby load on the stabilizer is illustrated.
  • a heel cut is seen in the line A_A.
  • the shoe comprises an upper part 301 and a sole 303.
  • the sole stabilizer 305 is show inside the sole 303 and the sole stabilizer 305 comprises respectively elongated elements 307, a shank 309 and plate elements 311 positioned at the endpoint of the elongated elements 307.
  • the elongated elements are bent due to pressure from the foot and further the stiffness of the elongates elements increases the stiffness of the sole in the transverse direction of the sole, whereas the flexibility in the longitudinal direction of the sole is not changed due to the sole stabilizer comprising transverse elongated elements, not changing flexibility in the longitudinal direction of the sole.
  • Alternative embodiments of the present invention is sole stabilizers made as segment elements only covering a subpart of the sole area, e.g. a specific segment with elongated elements having a first flexibility could be positioned at the front part of the shoe and another segment having a second flexibility could be positioned at the back part of the shoe. Again third and fourth segments could be added in the sides of the shoe.
  • the transverse flexibility of these sole stabilizers can be different based on the flexibility of the material in which they are made or based on the distance between neighbouring elongated elements.
  • Fig. 4A - D illustrate elongated elements positioned at different areas of a shoe sole.
  • elongated elements 401 are positioned at an area at the heel and at an area at the forefoot
  • in figure 4B elongated elements 401 are positioned at an area at the forefoot extending to the middle part of the foot
  • in figure 4C elongated elements 401 are positioned at an area at both sides of the forefoot and at one side of the middle foot
  • in figure 4D elongated elements 401 are positioned at a narrow area at the forefoot.
  • the elongated elements extend towards the side of in one transverse direction.
  • the transverse elements could alternatively extend in a direction corresponding to the flex direction of a foot wearing the shoe.
  • Figure 5A - C illustrate some of the areas as illustrated in fig. 4A-D , but where the elongated elements could be angled differently still extending towards the side of the shoe in a substantial transverse direction. Further the distance between elongated elements could also vary in different areas of the same shoe.
