Definitions

  • the invention relates to a shoe, in particular a women's high-heeled shoe, with a heel spot attached to the heel by means of a pin, the pin having a head which rotates through a breakthrough of the heel spot, is seated in an expansion sleeve of the heel in an expansion fit and has a circular cylindrical longitudinal bore into which a Spreading nail is driven.
  • the object of the invention is to optimize the rotation lock with structurally simple means and without increasing the number of basic components.
  • the definition of the heel spot against rotation is considerably improved.
  • the radially directed expansion effect occur due to the smaller longitudinal bore cross section compared to the expansion nail cross section; rather, the protrusions extending beyond a round cross-section of the expanding nail bring highly effective clamping ribs, the clamping pressure of which continues radially up to the jacket of the pin itself, which is in the press fit, and thus form zones of higher clamping force.
  • the non-circular cross-section has the advantage that the non-rotatability is retained even if the pin breaks.
  • the spreading nail thus practically functions as an internal turnstile. It is also advantageous if the expansion nail has a rectangular, preferably square, cross section.
  • the invention proposes that the pin shaft adjoining the head of the pin be provided with grooves in the longitudinal direction.
  • the fine ribbing achieved in this way brings a favorable coat roughening. This measure also contributes to securing against rotation.
  • the high-heeled shoe known as pumps, has a heel 1 that is practically the shape of a stirrup and tapered down to the area of a penny. Its underside 2 is covered with a plate of congruent plastic (PUR) or the like as a so-called heel spot 3.
  • PUR congruent plastic
  • the outer wall of the pin shaft 5 is grooved in the longitudinal direction to further secure rotation. A very narrow grooving results in a strong roughening.
  • the grooves have the reference number 8.
  • a smooth cylinder section 9 is attached to the section carrying the grooves 8 via a socket, which ends via a frustoconical section 10 into a cylindrical section 11, again with a reduced cross-section.
  • the heel spot 3 is provided with a cylindrical hole 12 in the central region.
  • the latter can be taken into account when punching out the stain.
  • the inside diameter of the hole 12 is matched to the outside diameter of the cylindrical section 11 with the smallest cross section.
  • the other end of the pin 4 forms a head 13 clearly projecting beyond the shaft cross section.
  • a cylindrical section 13 ⁇ adjoins first, which over a truncated cone Section 13 ′′′ merges into the cylindrical shaft 5.
  • Section 13 ′′′ accounts for approximately two thirds of the head length measured in the axial direction.
  • Notch-valley-like longitudinal grooves 14 extend in the axial direction over the entire length of the head jacket wall, leaving ribs 15 between them. The latter dig into the wall of the hole 12 or the wall material presses into the longitudinal grooves 14. This results in a toothed connection as a rotation lock between heel spot 3 and the pin 4.
  • the head 13 has a shorter axial length than the thickness of the heel spot.
  • a shoulder 16 can also remain between the head and shaft 5 of the pin 4, as can be seen in FIGS. 3 and 5.
  • the pin 4 has a central, circular cylindrical longitudinal bore 17.
  • the latter starts from the head 13 and ends in the region of the cylindrical section 9 of the shaft 5 and serves to receive an expanding nail 18.
  • the latter has a non-circular cross-section.
  • a square cross section is selected.
  • the diameter of the longitudinal bore 17, which is the same over the entire length, is kept somewhat smaller than the lateral dimension of the expanding nail with a square cross section. This results in a clamping effect which increases the clamping fit between pin 5 and clamping sleeve 6, which favors the rotation lock.
  • the projections 19 of the corner zones also formed by the non-circular cross section optimize this effect. These projections displace the material lying in front of their corner apex in the radial direction. According to the selected cross-sectional shape, there are permanently four zones Z of increased clamping-clamping force in the circumferential direction.
  • the expanding nail 18 has a pyramidal nail tip area 20. In contrast, its head is flat and not thickened. In the driven state, the flat head end 21 extends inward axially behind the head surface 13 hinter of the pin 4th
  • the expansion seat caused from the inside and the non-circular bridge between shaft 5 and head 13 of the pin ensure that the rotation lock is maintained even if the shaft breaks.
  • the pin 4 can already be assigned to the heel mark 3 by means of pre-assembly, so that this unit can be fixed as a whole; Another possibility, which is particularly conceivable for the repair operation, consists in the usual placement of the shoe stain 3 on the underside 2 of the heel and the subsequent driving in of the pin, after which the steel expanding nail 18 is then hammered in.
