Definitions

  • Such devices are usually metal guards either permanently or removably mounted at one or several locations of a shoe, principally at its toe end or at its counters, or at its shank portion and on a part or on the whole of its sole.
  • said elements are usually insulated or spaced from the foot either by embedding said elements within the thickness of the shoe itself, as it is the case for molded vulcanized rubber shoes or while the shoe is being manufactured, by interposing under the protective or reinforcing element a suitably profiled and dimensioned lining usually comprised of foam rubber.
  • the present invention is intended to avoid such drawbacks and has for its object a novel improved rigid protective or rein-forcing element for molded or otherwise fabricated so-cal'led safety shoes, said element being essentially characterised by the fact that it comprises, on its inside face, which may or not be covered by some fabric or other flexible lining, projections designed to contact, the shoe last through their inner ends, to ensure both proper positioning and maintaining of said elements relatively to said last in the course of the manufacture of said shoes.
  • Said reinforcing or protective element may present the following characteristics, taken alone or in combination:
  • said positioning projections are outwardly directed studs formed by stamping.
  • said projections are stud inserts pressed through holes formed in the protective element.
  • said element comprises suit-ably located holes to enable free flow of the molding substance there through.
  • the present invention has also for its object shoes provided with one or more of the above-mentioned protective elements.
  • FIG. 1 is a crosssectional view of one of said embodiments of the invention under the form of a protective toe guard, whose projections have been press formed;
  • FIGS. 2 and 3 represent two protective elements whose projections are inserts
  • FIG. 4 is an enlarged cross-sectional view taken along line 1VIV of FIG. 5.
  • FIG. 3 is a vertical cross-sectional view of a molded shoe provided with protective elements such as shown on FIGS. 2 and 3.
  • the protective or reinforcing element shown in FIG. 1 comprises a toe portion -1, preferably made of sheet metal, with inwardly directed projections 2, whose rounded tips are flush with the inner face of the finished shoe ('FIG. 5).
  • guards 1a to reinforce the shank portion and the heel counter of the shoe (FIG. 5), respect-vely.
  • Said guards comprise openings 3 (FIG. 2) into which studs 2a are engaged, said studs assuming the same function as projections 2 shown on FIG. 1.
  • the guard is, thus, automatically located so that it may be coated, on the one hand, with an inside layer 9, which is flush with said rounded ends and, on the other hand, with an outside layer 10.
  • openings 3 may be left opened in guards 1 or 1a to ensure that the injected material fills the free space left between the guard and the core of the mold, which permits the elimination of an inside blank.
  • a protective guard adapted to be embedded in a safety shoe while said shoe is being molded on a last, said guard comprising a stiff rein-forcing member formed with opopsed surface portions spaced to embrace between them a portion of said last, said opposed surface portions being provided with projections dimensioned to space said opposed surface portions from said last sufficiently to permit a molding material to flow and form a continuous sheet "between said last and said opposed surfaces when said last portion is embraced between said opposed surfaces.
  • a protective guard as claimed in claim 2 in which said reinforcing member is perforated and said projections are inserts made of elastic material seated in said perforations.
  • a protective guard as claimed in claim 2 in which some of said perforations are empty to permit said molding material to flow therethrough.
