Definitions

  • the present invention is encompassed in the field of footwear soles, and specifically those that include configurations that improve the cushioning on the tread.
  • Shoe soles are known which include configurations that project from the bottom sole of the sole upwards to serve as cushioning for the tread.
  • Some known configurations are arranged perpendicularly to the bottom sole of the sole, such as cone trunks or semi-spheres, which makes them suitable for high efforts or heavy users, that is, they cushion large loads so that in normal use they have no effect. and they become uncomfortable.
  • configurations of the slat type that are arranged inclined with respect to the bottom floor of the sole, which although they are more comfortable than the previous ones, are only suitable to withstand large and medium loads, which also make them uncomfortable.
  • the object of the invention is a shoe sole that includes configurations that improve cushioning in the tread of a user with respect to the known soles.
  • the technical problem to be solved is to configure the sole to reach the mentioned object.
  • the present invention relates to a sole for footwear comprising a lower floor and a side wall along the perimeter of the lower floor.
  • the lower floor comprises an anterior part corresponding to the anterior zone of a user's foot, an average part corresponding to the middle zone of the foot of a user and a back corresponding to the posterior area of the foot of a user.
  • At least a portion of the anterior or posterior part of the lower floor projects at least two protuberances, each one arranged and extended transversely to the longitudinal axis of the sole.
  • Each of the protuberances comprises a first segment in contact with the lower deck and a second segment following the first segment.
  • the sole is characterized by the fact that between the lateral ends of each protuberance and the lateral wall there is a first separation that allows the complete flexion of each protuberance, that is to say, since its movement on the sides is not limited, it can move freely.
  • the second segment is arranged inclined with respect to the first segment, between two adjacent protuberances there is a second separation so that when said protuberances flex by the support of a user's foot, the second segment rests at least in part on the adjacent protuberance; This creates a joint damping effect of the protuberances as one of them serves as a support to the adjacent one, so its effect is the result of the joint action, they do not work individually and a sole that does so would have a very different effect from the one here exposed.
  • each protuberance is divided into at least two fractions, with which the flexion is independent in as many parts as there are fractions, so it can be adapted to multiple parts of the same foot. That is, the fractions are independent and adaptable to each point of the foot, so that if there is a deformation in a specific point of the foot when stepping, it adapts to this specific shape thanks to the fraction, even if it is very small, and absorbs in that specific point, without affecting the rest of the sole, which will continue to adapt to each point and shape of each foot. Fractions are used to refer to dividing the same protuberance into sections, pieces or portions.
  • This effect is optimal when the inclination of the second segment of each protuberance is directed towards the front end of the sole at the front of the lower floor, and the inclination of the second segment of each protuberance towards the anterior part of the sole is directed towards said the back of the sole.
  • the arrangement and separation between the slats is such that it does not allow the use of a tool for machining the sole mold, but rather forces the use of different processes such as 3D printing.
  • the number of the bumps depends on the use that is You want to give because a sports shoe is different from a street one, as well as one for men or women. In this sense, it also depends on the use that is arranged in one area or another of the sole; for example, a women's heeled shoe has no space in the posterior area for any protuberances, and these are only arranged in the anterior zone.
  • Figure 1 represents a plan view of the sole.
  • Figure 2 represents a cross section of the sole.
  • Figure 3 represents a longitudinal section of the sole.
  • Figure 4 represents a perspective view of the sole.
  • Figure 5 represents a rear view in detail of some protrusions with braces, in a continuous line before flexing and in a discontinuous one after flexing.
  • Figures 1 and 3 show a shoe sole comprising a lower floor (1) and a side wall (2) along the perimeter of the lower floor, the lower floor (1) comprising a corresponding front part (1.1) to the anterior zone of the foot of a user, a medial part (1.2) corresponding to the medial zone of a user's foot and a posterior part (1.3) corresponding to the posterior zone of a user's foot, in at least a portion of the front part (1.1) or the rear part (1.3) of the lower floor (1) project at least two protuberances (1.4), in the figures 13 are shown in the front part (1.1) and 8 in the rear part (1.3), but their number will depend on the sole size as well as the intended cushioning.
  • Each protuberance (1.4) is arranged and extended transversely to the longitudinal axis (E) of the sole, understanding as a longitudinal axis the one that runs the sole from one end to the other and through its middle part, although it implies some change of direction as shown in figure 1.
  • each protuberance (1.4) comprises a first segment (1.41) in contact with the lower floor (1) and a second segment (1.42) following the first segment (1.41).
  • some of them may vary depending on their length, for example, the one shown has two sections, it can be considered as a third segment between the first (1.41) and the second (1.42), although this is only a representation since it could be that the first segment (1.41) was curved and of only one section.
  • each protuberance (1.4) is divided into at least two fractions, figures 1 and 4.
  • each protuberance (1.4) in two fractions in figure 4, however, each protuberance (1.4) is divided into several fractions, according to the area to be cushioned and depending on the use that is to be given, so for example it is normal that in In the area closest to the toes and metatarsal there are more fractions than in the other areas because the foot itself has more pressure and flexion points.
  • the height (H) of the protuberances (1.4) is greater than the height (h) of the side wall (2), shown in figure 2. Although it can be less than or equal, the damping is improved when it is greater since the protuberances (1.4) act on the user's foot before any other configuration.
  • protuberances (1.4) are joined by means of at least one partition (3), shown in Figure 1, arranged transversely to said protuberances (1.4) and of equal or less height than them.
  • This configuration provides rigidity to the set and although it can be arranged both in the anterior part (1.1) and in the posterior part (1.3), it is more usual in the latter because where the user's heel is located and therefore the highest loads during the tread .
  • other similar partitions can be arranged in the middle part (1.2) as shown in Figures 1 and 3 without numerical reference. These other partitions have only the mission of providing continuity to the configurations of the sole and in a very limited way they provide some cushioning although in that area the tread loads are minimal.
  • Another option shown in figure 5 is to have at least one tie rod (1.43) for each first segment (1.41), from the first segment (1.41) to the lower floor.
  • each protuberance (1.4) returns to the initial position it had. If the braces (1.43) are not arranged, with the walking and after many thousands of steps the protuberances (1.4) would give way, deform and lose effectiveness.
