Definitions

  • the present invention relates to a footwear, sole, and vamp of variable size, able to naturally and dynamically fit the dimensional variations that the user foot undergoes during the day and that can be applied to different types of footwear. Footwear built with this variable size type of sole and vamp will ensure a greater level of comfort to the user, which is transmitted through the continuous adjustment of footwear wedge to foot volume, all the time.
  • the present invention aims to address a problem commonly identified by people in general, namely wedge discomfort which arises from foot volume variability throughout the day, as a result of dimensional stiffness of sole and vamp size.
  • the solution presented, sole and vamp of variable size is made from a combination of several different components, an insole and an outsole, which engage pivotably, adjusting to one another and that, based on technical characteristics of the plantar structure, materials of high elastic capacity, and its process of vamp connection, the upper part of footwear, provide the footwear natural sliding and enlargement which naturally adjusts to the variable volume of the foot.
  • footwear its current function is dependent on a number of factors such as the activities carried out by people, the environment, and the physical characteristics of people, among others. So since the twentieth century it started a differentiation in footwear, emerging specific footwear according to occupations and sports, each with formal and functional characteristics in accordance to such professions and sports specificities, or the requirements of simple current use.
  • the morphology of the feet is variable depending on age, race, gender, specific physical states such as pregnancy or diabetes, and the weather conditions to which individuals are exposed.
  • the same foot exposed to cold or heat has different physical characteristics throughout the day, by the morning feet have a different volume than they have at night.
  • the same individual has different feet, whether minimal or significant differences.
  • the walking exercise itself causes changes in the shape of the foot resulting from the forces applied when different parts of the foot interact with the ground, and also because when a person is in the standing position, the foot expands and while in the sitting position, relaxation, the foot twitches.
  • adjustable size footwear (4) refers to a type of footwear composed by a variable size sole (1) combining two components, a insole (2) and an outsole (3) which engage with each other, pivotally to each other, and a vamp (4.1), upper part of footwear, connected together by simple sewing or through other joining process (4.2).
  • variable size sole (1) insole (2) and outsole (3) are made from elastomer polymer material and engaging between them is made in such a way that the variable size sole (1) expands its dimensions by adjusting the shape of the foot at each moment, through the action of sliding between the two components, the insole (2) and outsole (3).
  • This phenomenon is possible due to the dimensional and technical compatibilization of the structure of each of the component soles, insole (2) and outsole (3) forming the variable size sole (1), together with the materials that are produced and with the process of assembling of the shoe, and union of variable size sole (1) with the vamp (4.1).
  • the vamp fitting cavity (4.1) may enlarge by action of the foot forces exerted inside the footwear, causing the extension of the variable size sole (1) by sliding between the insole (2) and outsole (3), which means that the whole shoe extends in the metatarsal area, naturally adjusting to the dimension and variation of foot volume in every moment and returning to the original state when the shoe is removed, by action of the memory characteristics of the involved elastomers materials.
  • variable size footwear (4) presented in the present invention is characterized by the following structure and operation:
  • the variable size sole (1) is constituted by the combination of two components, a insole (2) which engages within an outsole (3).
  • insole (2) and outsole (3) are made of elastomeric polymeric materials with densities and thicknesses such that guarantee the necessary and sufficient elasticity for this purpose.
  • the insole (2) comprises a plantar structure with a lateral contour edge (2.1) and a track (2.2) that assembles a set of volumetric elements in the form of projecting surfaces (201), (202), (203) coupled to the base, which according to the lateral view (2.1) and section AA are constructed with inverted-I section, in which the geometry of smaller dimension is coupled to the base of the track and the larger geometry corresponds to the ground contact area.
  • the track (2.2) thus formed is characterized by a base structure on which are coupled to the projecting surfaces (201), (202), (203) giving it an appearance of embossed elements and giving to the base a combination of spacing between them.
  • the track (2.2) is characterized by the following characteristics: at the front part integrates two groups of projecting surfaces (201) of trapezoidal rectangular top geometry with rounded vertices, a projection (202) of circular geometry in the waist area and two sets of projecting surfaces (203) of square and semicircular geometry in the heel area. Both groups of projecting surfaces (201) are longitudinally separated from each other by a curvilinear line space corresponding to front plantar arc curvature of the foot. In each group the projecting surfaces (201) are oriented according to their greater length towards the sole width and are parallel and sequentially arranged to each other in small uniform spacing along the sole length.
  • More elongated dimensions in the group corresponding to the inner side of the sole and shorter dimensions in the group corresponding to the outer contour are presented by the projecting surfaces (201). Similarly, the two sets of projecting surfaces (203) are longitudinally separated from each other by a curvilinear line spacing corresponding to the foot plantar support curvature.
  • the outsole (3) consists of a high side contour edge plantar structure (3.2) imparting the sole a high inner housing (3.1).
  • This contour edge (3.2) is characterized by two different thicknesses, being the top contour edge (300) of lesser thickness.
  • the base of the outsole (3) consists of a composition of slits (301), (302), (303) with geometry compatible to the projecting surfaces (201), (202), (203) of the insole (2) and from which the engagement between the two soles, inner (2) and outer (3) will occur resulting in the variable size sole (1).
  • variable size sole (1) results from combination and fully articulated engage between the insole (2) and outsole (3), wherein elements (201), (202), (203) of the insole (2) pivotally fit the slits (301), (302), (303) of the outsole (3), and when subjected to external stresses may slide between them as elastics, i.e. naturally adjusting to the foot dimensional structure.
  • the adjustable size footwear finished (4) is obtained from the connection of the variable size sole (1) to the vamp (4.1) by means of lateral seams (4.2) between the two parts, or other junction system.
  • FIG. 6 it illustrates the adjustable size footwear (4) in its natural form or initial state (4.a) and in its state of expansion (4.b) when subjected to effort variation produced by foot volume variation.
  • FIG. 7 it illustrates in section, the shoe (4.a) in its initial position presenting the vamp (4.1), the insole (2), the outsole (3) and a sock (6).
  • the same Figure 7 also illustrates the adjustable size footwear (4) in a state of extension (4.b), showing the enlargement system in action, i.e., the outsole (3) extends and slides over the insole (2) leading to the enlargement (305); in this way the sole set of variable size (1) carries along the vamp (4.1), since this is sewn only to it and to no other internal component of the footwear, thus yielding the enlargement (306) of the lateral part of the shoe.
  • the insole (2) and the sock (6) are flexible and due to the force exerted by the foot inside the shoe, they are able to fit the shape acquired by the variable size sole (1), thereby creating the dynamic adjustment to the foot according to its volume variability.
