Definitions

  • An article of footwear having an outsole, a sole shell, an insole and an upper, in which, the outsole is formed as an internally and externally ridged member having a peripheral wall and defining a cavity on an inner side thereof, the sole shell being formed of reaction foam during a foaming operation and interfitting with the outsole inner side, the insole being connected to an inner surface of the sole shell and the upper, lower peripheral edge portions of the upper being connected between the insole and the sole shell, with the outsole being connected to the insole and upper via the 'sole shell during said foaming operation.
  • a sole for work or ski shoes which consists of an outsole which is flat on the inner side and a thermoplastic injection molded substance which stickes the upper shoe to the outsole and is mounted between the outsole and the upper shoe in a definite thickness which is dependent on the shape.
  • thermoplastic injection molded substance through which the'tough outsole is fastened to the upper.
  • thermoplastic injection molded substances not only thermoplastic injection molded substances but also other materials may be used as the outsole since the former are unsuitable as outsoles for ski shoes because of the danger of slipping on ice and snow and are unsuitable for work shoes due to their unfavorable temperature load.
  • Natural rubber is the most preferable material for the outsoles of non-slip ski shoes and,for example, synthetic rubber as the outsoles for heat-resistant work shoes. Both materials are, however, difficult to injection-mold and are'relatively expensive.
  • the present invention is a shoe, in particular a work or sports shoe of the kind initially men- Q of the outsole has indentations following the outer protioned, having a sole which is firmly connected to the shoe upper.
  • Another aspect of the present invention is the manufacture of such shoes.
  • an article of footwear comprising: an outsole formed as an inter-' nally and externally ridged member having a peripheral wall and a cavity portion on an inner surface thereof; a sole shell formed of reaction foam during a foaming operation and interfitting with the cavity portion of the outsole; an insole connected to an inner surface of the sole shell; and an upper, the lower peripheral edge portions of which are between the insole and the sole shell wherein, the outsole is connected to the insole and upper via the sole shell during said foaming operation.
  • the profile of the inner side of the outsole may follow the profile of the outer side of the outsole.
  • projections may be provided on the inner side of the outsole and a thin plate of a-material which cannot be penetrated, e.g. metal foil or solid plastic is supported in a precisely fixed position and said attachments.
  • a thin plate of a-material which cannot be penetrated e.g. metal foil or solid plastic is supported in a precisely fixed position and said attachments.
  • a further improved adhesion of the upper to the sole can be achieved if the foam core contains a wall bead extending over the edges of the peripheral wall of the outsole thus forming an additional-fastening surface for the upper.
  • a ridged outsole is inserted in a mold which is then covered by an upper seated on alast.
  • the remaining free inner space between the inner side of the outsole and the upper is then filled with a soft elastic reaction foam firmly adhering the outsole to the upper.
  • the ridged outsole consisting of a conductive material is to be filled with a likewise conductive reaction foam system which provides the conductive connection between the upper side of a non-conductive insole provided with holes and the ground, wherein the holes of the insole are likewise filled with the foamed material.
  • a'shoe upper 8 consisting of a shaft or angle portion 6 and an insole 7 is directly stuck to a padded sole consisting of a reaction foam core and a ridged outsole 3 with a nonpenetrable thin plate 9 of metal or like material embedded therebetween.
  • This plate 9 is supported on integral projections 10 of the outsole 3 which extend inside the outsole ridges and accurately fix the non-penetrable plate 9.
  • the non-penetrable plate 9 By securing the non-penetrable plate 9 in the padded sole and enclosing it on all sides in soft elastic foamed material, the stresses which automatically occur during use on bending the shoe can be compensated for thus resulting in a greater durability of the shoe and the new soles.
  • a front part 11 of the outsole which is particularly subjected to wear and tear is sturdier than the remaining outsole walls which provides a further improved working life of the sole.
  • the foamed material for forming a so-called sole shell is raised up in the form of a peripheral bead 12 laterally on the upper. This can be achieved by suitably shaping the sole mold.
  • the upper 8 clamped on a last is inserted as a closureyon a mold in which the outsole 3 has already been .placed.
  • a metal conduit which leads to the die (all not shown)
  • the interspace between the shoe upper and the mold is injected with reaction foam whereby the tough outsole and the upper are firmly connected together with the formation of an inflated padded core.
  • the nonpenetrable layer 9 consisting of sheet steel is fixed on the attachments 10.
  • FIG. 2 illustrates a further pad ded sole according to the invention which is similar to the embodiment according to FIG. 1.
  • the tough outsole 3 consists of an electrically conductive elastomer material, and j the foam core 5 is also conductive. Apertures 19 are provided in the insole 7 and during-filling with conductive reaction foam, these are filled up to anadjoining last 20 supporting the upper 8.
  • the foam core of the padded sole according to the invention extends over the entire tread of the shoe, the shoes are extraordinary light-weight and very comfortable when walking.
  • the present soles are, therefore particularly, suitable for orthopaedic foot-wear.
  • the large surface fixed connection between the outsole and the padded core furthermore, has the advantage that relative displacements between the padded core and the outsole or between the padded core and the shoe upper cannot occur.
  • the shoes or boots manufactured according to the present invention have the important advantage that particularly high strength factors of the reaction'foam can be dispsnsed with since good support and abrasion properties are provided by the pre-prepared outsole.
  • a cheaper reaction foam based on polyether can also readily be used for heavily stressed footwear.
  • An article of footwear comprising an outsole, a sole shell, an insole and an upper, wherein, the outsole is formed as an internallyand externally ridged member having a peripheral wall and defining a cavity on an inner side thereof, the sole shell is formed of reaction .foam during a foaming operation and interfits with the outsole inner side, the insole'is connected to an inner surface of the sole shell and the upper, lower peripheral edge portions of the upper being connected between the insole and thesole shell, the outsole being connected to the insole and upper via the sole shell during said foaming operation.
  • the article of footwear of claim 2 further comprising a non-penetrable plate supported on projections on the inner side of the outsole, reaction foam being disposed between the non-penetrable plate and the insole and upper as well as between the non-penetrable plate and the outsole, the nonpenetrable plate being held in position on the projections by the reaction foam.
  • peripheral walls of the outsole are thinner than a tread surface of the outsole.
  • a method for manufacturing an article of footwear including an outsole, a sole shell, an insole and an upper in which the outsole is formed as an internally and externally ridged member having a peripheral wall and defining a cavity on an inner side thereof, the sole shell being formed of reaction foam during a foaming operation and interfitting with the outsole inner side, the insole being connected to an inner surface of the sole shell and the upper, lower peripheral edge portions of the upper being connected between the insole and the sole shell, and the outsole being connected to the insole and upper via the sole shell during said foaming operation, comprising the steps of: placing the outsole into a mold; clamping the upper and the insole on a last; closing said mold with the last having the upper and insole clamped thereto; and filling the inner space between the inner surface of the outsole and the insole and upper with reaction foam to firmly adhere the outsole to the upper and insole.
  • a method for manufacturing an article of footwear including an outsole, a sole shell, an insole and an upper in which the outsole is formed as an internally and externally ridged member having a peripheral wall and defining a cavity on an inner side thereof, the sole shell being formed of reaction foam during a foaming operation and interfitting with .the outsole inner side, the insole being connected to an inner surface of the sole shell and the upper, lower peripheral edge portions of the upper being connected between the insole and the sole shell, and the outsole being connected to the insole and upper via the sole shell during said foaming operation, comprising the steps of placing the outsole formed of electrically conducted material into a mold;
