Definitions

  • the present invention relates to a sole for a shoe in particular a running shoe.
  • the design of the sole is of particular importance. This part of the shoe combines several functions. On the one hand the sole should, depending on the intended use of the shoe, provide a sufficient cushioning to reduce as much as possible the arising stress on the human body.
  • the design of the lower part of the sole determines on the other hand the interaction of the shoe with the ground. One objective is to optimize the grip of the shoe on the ground.
  • running shoe comprises all kinds of shoes where the sole directly contacts the ground, as for example jogging shoes or sprint shoes but also shoes for everyday use and hiking boots. It is for example obvious that a sole for a hiking boot to be used on rough ground comprises preferably a coarser profile structure than a sports shoe for indoor sports.
  • Running shoes for trail running for example are often used on a plurality of different surfaces.
  • the athlete runs over long distances not only on even asphalt roads but also on gravel roads or woodland trails.
  • the ground might further be either dry and hard or wet and muddy. This leads to the desire of the manufacturer of such shoes to construct soles providing on a plurality of grounds a sufficient grip to allow the multipurpose use necessary for a trail running shoe.
  • the US 5,634,283 discloses a golf shoe where metal tips for the improvement of the grip on soft ground, for example grass, are flexibly anchored in a sole.
  • the pressure on the shoe caused by the weight of the wearer of the shoe pushes the metal tips into the sole so that on hard ground the grip is only provided by the other parts of the sole.
  • the US 4,398,357 discloses a shoe with a sole consisting of two materials with different densities. Whereas a more dense and therefore more wear resisting material is used in the heel and ball parts, the intermediate part of the sole arranged below the arch of the foot is manufactured from a less dense and therefore more lightweight material in order to reduce the overall weight of the sole.
  • the US 5,926,974 discloses a sole designed according to the hoof of a mountain goat. To this end several soft protruding profile elements are provided, surrounded by a sequence of comparatively hard lugs attached to the outer perimeter of the sole. The hard lugs limit the compression of the soft profile elements and improve the grip on an irregular ground.
  • the present invention relates to a sole for a shoe, in particular a running shoe with at least one first ground engaging profile element having a first flexibility and at least one second ground engaging profile element having a second flexibility, where the second profile element has a ridge- or riblike shape and the second flexibility is greater than the first flexibility.
  • the effect according to the invention for the adaptation to the roughness of the ground is achieved: On a comparatively even surface, for example asphalt or the surface of a gymnasium, the first and second profile elements together provide the great contact area of the sole necessary for a good grip.
  • the at least one more flexible ridge- or riblike profile element is deflected by protrusions of the ground so that with the at least one first profile element a comparatively rough sole is obtained.
  • the second profile element is capable to penetrate the ground or to engage the protrusions of the ground whereby the grip of the sole under these ground conditions is improved.
  • this property of the second profile element which can also be characterized as a lamella-like structure, assures together with the less flexible first profile element the necessary adaptability to the corrugation of the ground of the sole according to the invention.
  • the height of the first profile element preferably slightly exceeds the height of the second profile element.
  • a plurality of second profile elements are arranged around the at least one first profile element.
  • an isolated first profile element is obtained, when the second profile elements are deflected, as described above, which is well suited to engage a rough surface.
  • the second profile elements consist of 1 to 2 mm wide parallel ridges having a distance of preferably I to 2 mm from each other. This assures that the ridges can deflect on a rough surface independently of each other to obtain the above described effect.
  • first profile elements are arranged in the forefoot and midfoot part of the sole, since these are the areas of the sole being decisive for the grip during push-off from the ground.
  • the first profile elements are essentially sickle shaped and perpendicularly oriented with respect to the longitudinal axis of the sole to support in particular a forwardly directed push-off.
  • additional first profile elements can be arranged along the outer edge of the midfoot and forefoot part.
  • a preferred embodiment of the present invention comprises a sole 1 with essentially two groups of profile elements (cf. Fig. 1).
  • profile elements 10, 20 of the two groups are provided with reference marks in the Figs. 1 and 2.
  • the following description relates to all profile elements of the respective group, where variations within one group concerning the size and the orientation are possible.
  • first profile elements 10 are arranged preferably on the medial and lateral midfoot part and the lateral forefoot part of the sole 1 which are preferably embedded into a plurality of ridge- or riblike profile elements 20.
  • This arrangement of the elements 10, 20 corresponds to the fact that these parts of the sole 1 are of decisive importance for a good grip, in particular during the rolling-off and pushing-off phase of the step cycle.
  • additional profile elementsl0, 20 can be arranged in the heel part of the sole 1 (not shown).
  • the profile elements 10 are in their original configuration preferably 0.5 mm higher than the second profile elements 20, so that under a compression by the weight of the athlete both groups of profile elements simultaneously contact the ground .
  • a comparatively dense profile results, as can be seen in the perspective representation of Fig. 2, providing a good grip on an even ground like an asphalt road or the surface of a gymnasium.
  • the height of the profile elements is approx. 5 mm.
  • other vertical dimensions preferably between 1 and 10 mm, are also possible.
  • the profile elements 10 preferably consist of a comparatively hard and therefore inflexible material. They deform only slightly under stress during the ground contact and are therefore capable to penetrate the ground, on which the sole according to the invention is used.
  • the preferred hardness is in the range of 65 A.
  • the ridge- or riblike profile elements 20 are preferably made out of a soft and sticky rubber, providing a great flexibility and a good grip even on wet surfaces. Their preferred hardness is in the range of 60 A. Due to their greater flexibility, the profile elements 20 are forwardly or backwardly deflected (cf. arrow in Fig. 2). As a result, they retract compared to the first profile element 10 and do no longer extend as far downwards as the first profile elements 10. This happens in particular during running on grounds with a great roughness, as for example gravel roads. By the deflection of the second profile elements 20 the resulting overall profile of the sole according to the invention is dominated by the harder profile elements 10 so that a comparatively rough sole 1 is obtained.
  • ridge- or riblike second profile elements 20 is shown in Figs. 1 and 2 with parallel, preferably perpendicularly to the longitudinal axis of the sole oriented ribs, also other shapes and arrangements of the ridge- or riblike second profile elements 20 are possible. Conceivable are for example concentrical rings around the first profile elements 10 or irregularly arranged longitudinal units with an arbitrary orientation.
  • the single ridges 20 have a width of 1 to 2 mm and a distance which is also between 1 and 2 mm. These values, however, are only rough values. In detail, the distance of the profile elements 20 with respect to each other is determined by the requirement that they do not interfere with each other when they deflect and loose thereby the required greater flexibility with respect to the first profile elements 10.
  • the first profile elements 10 have an essentially sickle shaped design and are oriented, as the second profile 20, essentially perpendicularly to the longitudinal axis of the sole. Thereby they support in particular a forwardly directed push-off of the wearer of the shoe. Possible are also other shapes and orientations of the first profile elements 10, for example a Z-like shape.
  • additional first profile elements 11 are arranged along the medial and lateral edge of the midfoot and forefoot part, where their orientation follows essentially the course of the edge of the sole 1.
  • additional other separate profile elements 12 are arranged perpendicularly to the longitudinal axis of the sole in the forefoot part to provide also in the last phase of the step cycle a good grip.
  • the medial and center part of the forefoot is preferably provided as a stable rolling-off surface 31 extending upwardly from the sole over the front part of the upper of the shoe (not shown) to increase the lifetime of the shoe.
  • this rolling-off surface 31 is ribbed, other profile shapes are also conceivable.
  • a continuous groove-like indentation 40 Between the forefoot part and the midfoot part extends preferably from the medial to the lateral side a continuous groove-like indentation 40.
  • this indentation 40 the bending stiffness of the sole is selectively reduced in order to impair the natural rolling-off movement of the foot with the toes as little as possible.
  • additional ribs 50 are provided in the rear part of the midfoot part close to the arrangement of the first and second profile element 10, 20.
  • the additional ribs 50 have preferably a mirror-inverted orientation and shape with respect to the first profile elements 10.
  • the additional ribs 50 serve to decelerate the shoe during the landing on the ground.
  • the additional ribs have metal surfaces to improve the grip on soft ground.
  • a reinforcing element 60 is arranged between the midfoot part and the heel part which simultaneously supports the arch of the foot.
  • the reinforcing element 60 is preferably a rigid structure element of the sole 1, preferably made out of a stable plastic material.
  • the reinforcing element 60 encompasses the sole 1 on its medial side and has therefore a three-dimensional shape. In the embodiment shown in Fig. 2 the reinforcing element extends into the heel and midfoot part; the degree of the extension, however, may vary. Conceivable is also that the reinforcing element 60 extends over the complete width of the sole 1 up to the lateral side.
  • the heel part of the sole comprises preferably on its lateral side a damping element 70, since the major part of athletes contacts at first with this part of the sole the ground whereby the greatest stress arises.
  • the damping element 70 extends over the complete heel part.
  • the surface of the damping element may, as already mentioned, comprise, additionally to the midfoot and forefoot part, the combination of first and second profile elements 10, 20 according to the invention; the embodiment of Fig. 2 shows for the sake of simplicity a simple grooved profile.
  • additional ribs 80 are arranged on the medial side of the heel part which avoid by their preferred inclined orientation a sideways sliding of the shoe immediately after the first ground contact.
