Definitions

  • the present invention relates to a shoe sole for fitting with ease different widths of feet; it also relates to the shoe fitted with such a sole as well as the method of mounting this shoe.
  • the shoes are traditionally made with a width chosen by the manufacturer. This width is more or less important but it is predetermined; it does not vary depending on the width of the user's foot.
  • the device according to the invention overcomes these drawbacks.
  • a sole comprising at least one extendable zone in the forefoot part; thus, during use, the manufactured shoe conforms to the anatomical width of the foot on its lower part.
  • the transversely extendable forefoot part is obtained by molding (or gluing) on a sole base one or more inserts of a material with a deformable structure endowed with a potential d elasticity and shape memory adapted to the desired comfort.
  • This extendable insert is flat on the upper face and provided with one or more projections on the lower face. These projections are intended to be embedded in the bottom of the sole.
  • the sole base is made from a material of the conventional type such as leather, elastomer, rubber, polyurethane or any other material traditionally used in the manufacture of shoe soles and having normal characteristics of resistance to abrasion.
  • the sole base has openings intended to receive the projections of the lower face of the extendable insert, while preserving the tightness of the connection between the two materials.
  • a first assembly consists of one or more perforated zones in its forefoot part and a rigid rear part. This structure of the front part of the first mounting allows the transverse deformation of the forefoot area.
  • the deformable part of the forefoot can be produced only by the juxtaposition of longitudinal slots.
  • the deformable part of the forefoot can be obtained by making one or more longitudinal openings, these being filled or not by molding or gluing one or more inserts of extensible material.
  • the invention also relates to the footwear article fitted with the extensible sole just described.
  • this article of footwear consists of a rod, of the first mounting with a deformable forefoot part and a rigid rear part, of a first of cleanliness not glued in its peripheral part and of the sole with extensible insert according to the present invention.
  • the mounting method for this footwear consists in preparing a first fitting with a rigid part at the rear and a deformable part in the forefoot area.
  • the rod is mounted on said first mounting and glued to the sole fitted with its extendable insert.
  • FIG. 1 shows the sole seen from below.
  • Figure 2 is a longitudinal sectional view of the sole.
  • Figure 3 is an exploded view of the bottom of the sole assembly, elastic insert and first assembly.
  • Figure 4 is a sectional and perspective view of a shoe equipped with the system.
  • the sole shown in FIGS. 1 and 2 consists of a sole base (1) and an insert of extensible material (2) assembled by molding or by gluing in order to ensure sealing between the two materials.
  • the protruding pinsert (3) are positioned in the openings (4) made in the bottom of the sole. In the embodiment shown, this type of parallel installation allows the addition of the elasticities of each projection (3).
  • This complex, rigid sole base and extensible insert provides a sufficiently structured sole to adapt to traditional welded manufacturing.
  • FIG. 3 represents a stack of independent supports with deformable and extensible properties.
  • the bottom of the sole (1) made of rigid material is made deformable by the openings (4) made in the forefoot area.
  • the insert (2) whose projections (3) are embedded in the openings (4) of the base of the sole (1) is an expandable seal.
  • the first mounting (5) is equipped with a forefoot portion made deformable by the presence of the longitudinal slots (6) and a rigid rear portion (7) In the assembly shown in FIG. 4, this configuration allows to keep the elasticity on all the floors once the assembly is finished.
  • the bottom of the sole (1), the insert (2) and the first mounting (5) have extendable characteristics outside the bonding zones (9) -.
  • the first interior (8) not bonded on its periphery does not block the deformation of the lower layers. It is the pressure of the foot applied to the outer edges of the rod (10) which induces the deformation of all of the superimposed stretch layers.
  • the dimensions of the insert at the level of the projections will be of the order of 3.5 mm in thickness and 7 mm in width. Of course, these dimensions are only indicative; they can vary depending on the size and comfort that you want to give the shoe.
  • This shoe structure gives a walking comfort which is particularly suitable for "sensitive feet articles", but of course this extensible structure may be envisaged for other types of mounting than the welded or other types of footwear.
  • the present invention is particularly intended for the manufacture of shoes having the capacity to adapt to different widths of feet.
