Definitions

  • the object of this invention is a shoe provided with an interposed cavity which can be inflated with compressed air to regulate the flexibility of the sole.
  • the shoe should furthermore ensure maximum comfort and waterproofness under any conditions and should be capable of easy, repeatable and low-cost production.
  • a shoe formed by an upper and by a flat sole of the type comprising an air chamber made up of compartments, capable of being inflated by means of valves, in which the flat sole is provided with a raised perimetrical edge to which are made integral such air chamber, a rigid countersole and the upper by means of stitching, gluing or the like, there being also included in such flat sole a rigid layer, such combination providing a flexible cavity capable of allowing flat and parallel relative movement of the arch support of the shoe in relation to the outer sole.
  • such compartmented air chamber is made integral with the sole in a reversible manner, and furthermore such raised edge of the outer sole is provided with at least one through hole at right angles to the surface of the said edge.
  • Such rigid layer integral with the outer sole to be preferably included within the thickness of the said sole, albeit divided into two parts, comprising a front part and a rear part, articulated to one another by means of a transverse-axis hinge.
  • such rigid countersole is in turn divided into two parts, comprising a front part and a rear part, articulated to one another lengthwise by means of a transverse hinge, such front and rear parts being delimited peripherally by a raised edge capable of being made integral with the matching raised edge of the outer sole.
  • shoe 1 As shown in the figure, shoe 1 according to the invention consists of an upper part commonly known as an upper 2, the lower part of which is formed according to the right or left shape of the foot.
  • a perimetrical strip 2b made of the same material as used for upper 2, capable of being turned from top to bottom, and vice versa, around such line of stitching 2a, as will become more clearly apparent from the following.
  • the part of the shoe forming the sole is in turn formed of several parts made integral with one another; more particularly it consists of an outer sole 4 which has a surrounding vertical band 4a provided with holes 4b on a horizontal axis; in such outer sole 4 is furthermore included, using a method known in itself, a thin layer 5 of rigid material capable of imparting greater rigidity to the said sole.
  • Such layer 5 is divided into two parts, a front part 5a and a rear part 5b, which are articulated to one another by means of a transverse hinge consisting of a thin strip of flexible material.
  • an air chamber 6 suitably shaped (figs. 2 and 4) which, as shown in the figures, is preferably divided into three spaces capable of being inflated separately and corresponding respectively to heel area 6a, arch support area 6b, 6c and toe area 6d.
  • Each of these spaces is then connected, by means of a perforated cylindrical chamber 7, to one-way valves 8 through which it is possible to pump into each space the volume of air needed to obtain the desired rigidity; in order to allow improved distribution of air in such spaces they are isolated from one another as illustrated in figure 4, and more precisely heel 6a is independent, two spaces 6b of the arch support are connected to one another and a third space 6c of the arch support is connected to spaces 6d of the toe, such gluing being carried out by means of connecting channels 109.
  • spaces 6a and 6d are furthermore separated transversally from spaces 6b and 6c by thin-transverse, continuous, solid strips 9 made of the same material, acting as a transverse-axis hinge around which such spaces are articulated to enable them to adapt to the different movements of the foot when walking.
  • spaces 6b and 6c of the arch support are divided by like strips 9a of material arranged longitudinally.
  • Such air chamber 6 is made integral with outer sole 4 by means of perforated cylinders 7 restraining valves 8, which are forced into holes 4b of edge band 4a until each circular edge flange 7a protrudes from holes 4b, causing the locking of air chamber 6 to sole 4.
  • a countersole 10 which is divided into two parts, front 10a and rear 10b, by means of a strip 10c of thin material forming a horizontal/transverse-axis hinge which allows articulation of the front part relative to the rear part in the manner already described for air chamber 6.
  • Countersole 10 is then completed by a surrounding vertical edge 10c the height of which is such as to arrive substantially at the level of the upper free end of edge 4a of outer sole 4 (fig. 3).
  • band 2b is turned down to overlap edge 4a, whereupon the shoe is made ready for final stitching 11.
  • Such final stitching not only makes upper 2 integral with outer sole 4, but also fixes in relation to the latter the assembly formed by air chamber 6 and countersole 10, thus making it possible for such assembly to function as a proper shock absorber having two fixed points: at the top, the final stitching, and at the bottom the outer sole and therefore the ground, the regulation of the stiffness of such shock absorber being achieved by the higher or lower internal pressure of the air chamber.
  • countersole 10 makes it possible to obtain uniform distribution of the pressure of the air chamber on the plan of upper 2, and therefore on the wearer's feet, which pressure would in the absence of the countersole be concentrated in much smaller surface areas which would be equivalent, in regard to the feet, to the presence of foreign bodies such as pebbles or the like inside the shoe.
