Definitions

  • the rear sole portion whichis drawniforward ap proximately to the shank area.
  • Attached to the supporting structure is an insole, independently formed of pressed fiber material, which extends the entire length of the shoe so that a part thereof projects from the supporting struc-' ture to the tip of the shoe and forms a flexible sole for the shoe.
  • the shoe finally includes a heel, attached to the supporting. structure, andupper material covering the outer sideof the supporting structure.
  • the present invention relates to the construction and manufacture of shoes. and particularly ladies shoes with heels and a shape-retaining frame work which consists of a molded piece of plastic which is provided with a rigidv insole part extending between the heel and ball areas of the shoe and of a counter which is integrally connected to the rigid insole part and is drawn forwardly approximately to "the shank area of the shoe.
  • the outer side of the framework is covered by the material of the upper of the shoe.
  • the framework of such a shoe which may be produced in a simple manner, for example, by molding or diecasting not only forms the, shape-retaining support of the shoe, butit. also serves as a shape-retaining base: for the leather upper.
  • the operation of shaping the rear part of the upper on a heel forming machine which was previously required therefore become-s unnecessary. This not only results in a considerable simplification of the manufacture of such shoes and a reduction of its costs, but it also permits the use of thinner leather of a lower quality without requiring the use of an intermediate lining within the shoe.
  • the molded framework of plastic for such a shoe may in each case be made accurately in accordance with the shape of a last, the entire shoe may be made to fit much more accurately than one in'which the material of the upper, for example, leather, forms the shape-producing element.
  • this object is attained by combining the rigid insole part ofthe framework with a counter which is provided with flexible and elastic side walls.
  • the elasticity of the counter insures that the rear part of the upper will properly retain its shape and that the shoe will adapt itself very accurately to the particular shape of the part of a foot between the heel and shank.
  • the elastic counter of the otherwise rigid framework therefore results in a very accurate and lasting fit of the shoe.
  • the framework is preferably made of an elastic plastic, for example, nylon, and for stabilizing the framework in longitudinal direction, the lower side of its rigid insole part is provided with one or more reinforcing ridges. For ladies shoes with high heels it may beadvis a'ble toprovidean additional arch support by embedding a strip of spring steel in the rigid insole part or in a reinforcing ridge thereon.
  • a padl ike bulge may be molded upon the upper side of the rigid insole part at theinner side of the shank for lifting the arch.
  • the disadvantage that especially in ladies shoes the upper often becomes deformed in the course of time at the inner side of the shank may be prevented in a shoe according to the invention by making the forwardly-driven counter of a greater solidity than the other parts of the framework. 7
  • FIGURE 1 shows a perspective view of the framework of a shoe according to the invention
  • FIGURE 2 shows a cross section which is taken along i the line IIII of FIGURE 1; while FIGURE 3 shows a perspective view of the finished shoe which is provided with a framework according to FIGURES l and 2 .and from which a part is cut away to illustrate the structure of the upper.
  • the shoe according to the invention comprises a frame-work which is molded of plastic and substantially consists of an elastic counter 1 which is drawn forwardly approximately to the shank area of the shoe, and a rigid insole part 2, the lower side of which is provided with a reinforcing ridge 2' and on the heel area of the latter with a downwardly extending projection 2" of an angular shape.
  • this projection 2" engages tightly into a corresponding recess in the upper side of the heel 3 for the purpose of centering the heel and of preventing it from being twisted relative to the insole part 2.
  • This projection 2" as well as the reinforcing ridge 2' are molded or die-cast integrally with the remainder of the framework.
  • the framework is further strengthened especially in its longitudinal direction by a strip 4 of spring steel which is embedded in the rigid insole part 2.
  • the reinforcing ridge 2 is preferably designed so that its lower surface terminates in alignment with the lasting margin of the upper 5 which in the finished shoe covers the outer side of the framework. In this event there is no need to fill out the area which is enclosed by the lasting margin.
  • this insole part is formed by an extension 6' of a solid covering 6 which is provided on the upper side of the rigid insole part 2 and preferably consists of a moisture-absorbent material, for example, a layer of compressed leather fibers.
  • the counter 1 is covered by a lining 7.
  • a shape-retaining supporting structure molded of an elastic plastic material and comprising a substantially rigid rear insole portion extending from the heel area substantially to the ball area of the shoe, a counter having elastic side walls which is integral with said rear insole portion and drawn forwardly substantially to the shank area of the shoe and at least one reinforcing ridge on the lower side of said rigid insole portion for stabilizing said supporting structure in its longitudinal direction; a heel secured to said rigid insole portion; and upper material covering the outer side of said supporting structure.
  • a shoe comprising, in combination:
  • a shape-retaining supporting structure molded of a plastic material, said structure having a substantially rigid sole portion extending from the heel area substantially to the ball area of the shoe and a counter, integral with said rear sole portion, which is drawn forward approximately to the shank area of the shoe;
  • an insole independently formed of pressed fiber material and attached to said supporting structure, said insole extending the entire length of the shoe so that a part thereof projects from said supporting structure to the tip of the shoe and forms a flexible sole for the shoe;
