Definitions

  • the present invention relates to reinforced heels of plastic or other weak materials. 'Ihe invention is particularly related to reinforced heels of relatively very srnall cross section for use in womens shoes.
  • Heels of the above-described character are exceedingly weak, wherefore, in order to prevent fracture thereof, during use, they have been strengthened by reinforcing dowels driven into longitudinally extending recesses thereof.
  • the reinforcing dowels have had a tendency to turn in the recesses of the heels.
  • An object of the present invention is t provide a very simple solution of the problem that, despite its simplicity, has unexpectedly been found to 2be very eflective, in practice.
  • a feature of the invention is to eliminate altogether the ribs heretofore ernployed, but to employ an ordinary reinforcing dowel of round cross-section.
  • the tread e'nd of the reinforcing dowel carries the top lift, and its heel-seat end is driven into the body of the heel.
  • This heel-seat end departing from the prior heel art, is chiselshaped After the reinforcing dowel has been driven into the heel, it is impossible to turn it.
  • the chiselshaped end of the dowel bites into the weak material of the body of the heel; but that is no disadvantage, because this occurs in a portion of the heel, near the heel seat, where the heel is quite wide, and not in the thin cross-sectional parts of the hee1, where the ribs have heretofore been employed.
  • the only weakening moreover, is at the two opposite edges of the chisel; in between these two opposite edges, on both sides of the chisel, the material of the heel is totally unweakened. Unlike the ribs of the prior-art dowels, therefore, the chisel does not weaken the heel.
  • FIG. 1- is a perspective of a heel constructed in accordance With a-preferred embodimentof the present invention.
  • FIG. 2 is an enlarged view, partly broken away, of a preferred reinforcing dowel, With a top-lift blank secured thereto.
  • the reinforced heel that is illustrated by FIG. 1 is shown having a body portion of relatively weak material, such as plastic, provided With a relatively large heelseat end 2, a stem 4 of relatively small cross-section, and a relatively small tread end 6.
  • the body portion is interiorly provided With a recess 8 extending longitudinally from the tread end 6 to near the heel-seat end 2.
  • An elongated reinforcing dowel 10, constituted of material, such as steel, that is much harder than that of the body portion is shown provided With a chiselshaped heel-seat end 12 and a tread end 14. Except for the tread end 14, the reinforcing dowel 10 is driven into the recess 8 to a point near the heel-seat end 2 of the body portion, as shown by dashed lines in FIG. 1.
  • the tread end 14 of the rei.nforcing dowel therefore, extends downward, beyond the body portion, to receive a top lift blank 16, as shown in FIG. 2
  • the blank 16 becomes later shaped into the form of a top lift 18, as shown in FIG. 1.
  • the diameter of the reinforcing dowel 10 may be the same 0.141 inch that has heretofore customarily been employed.
  • the formation of the ribs that have been provided upon prior-art dowels have resulted in reducing this diameter from the customary 0.141 to 0.135 inch. T0 that extent, the re'mforcing dowel 10 of the present invention is stronger than the said ribbed reinforcing dowel of the prior art.
  • a reinforced heel having a body portion of a relatively weak material provided with a relatively large heel-seat, a stem of relatively small cross-section, and a relatively small tread end, the body portion being interiorly pr ovided With a recess extending longitudinally from the tread and to near the heel-seat end, an elongated reinforcing dowel of round cross-section constituted of material much harder than that of the body portion provided With a heel-seat end and a tread and, the reinforcing dowel, except for the tread end, being driven into the recess to a point near the heel-seat end of the body por- 4 tion, the heel-seat end of the dowel being chisel-shaped with a chisel blade extending substantially the width of the dowel to prevent rotation of the dowel in the recess, and a top lift secured to the tread and of the dowel.
