Definitions

  • This invention has for its object to provide an improved arrangement for holding a very easily exchangeable tread part which can be removed and replaced-also without the aid of a shoemaker if necessary.
  • the arrangement must be such that the tread part is retained very firmly and, especially, pre vented from turning relative to the rest of the heel, and furthermore-it must be possible to remove even a very Worn tread part without damagingthe mechanism.
  • This invention offers a solution of this problem, which is both simple and-effective.
  • the main feature of the invention is that the stem of the exchangeable tread part has an unround, preferably square, crosssection and is adapted to be received in a matching cavity in-the lower end of a socket member,
  • the heel end portion is provided with a tubular extension extending upwardly through the rest of the heel and having an open upper end through which a suitable tool may be inserted to actuate the socket member in a downward direction against the action of the spring for the purpose of releasing the stem of the tread part, when replacement of said tread part is desirable.
  • FIG. 1 shows a ladies shoe heel with an exchangeable tread part and an attachment therefor according to the invention
  • FIG. 2 is an enlarged vertical section through the lower portion of the same ladies shoe heel accommodating the attachment mechanism for the tread part
  • FIG. 3 is a cross section taken along the line IIIIII in FIG. 2,
  • FIG. 4 shows the heel end portion as viewed from below with the tread part removed
  • FIG. 5 is a top plan view of the tread part.
  • numeral 1 designates a ladies s'hoe heel made for instance of wood, plastic or the like and nor- 3,299,542 Patented Jan. 24, 1967 "ice the heel end portion 2 and the tubular extension 3 must,
  • the replaceable tread part 4 which is to be attached to the heel end portion '2 and which may be made of metal, plastic, leather or the like, is provided with a centrally protruding stem 5 of square or at all events unround cross. sectional shape.
  • This stem 5 is adapted to be inserted in a corresponding square hole or cavity 6 in a socket member 7 moulded in plastic, preferably of the polyam-ide resin type such as the synthetic resin materials sold under the trade names nylon or Delrin.
  • the lower cavited portion 7 of said socket member 7 is axially-slotted and has in its turn a square outer cross sectional contour (see particularly FIG. 4).
  • one diagonally extending slot 8 only is provided in the lower portion of the socket member 7 in order to avoid atoo extensive weakening of the socket member but, if
  • the size and material of the socket so percross sectional dimensions of the square lower portion 7 of the socket 7 are gradually increasing in the downward direction while the upper portion of the socket -7 is cylin- "drical and has a threaded top end 7" on which a sleeve nut 9 with a slotted head 10 is screwed.
  • a helical compression spring 11 which urges the socket 7 inwards and upwards through the heel end portion 2, the lower hole mouth 12 of which is adapted to fit the lower portion 7' of the socket 7 insofar that it is square in cross section and inwardly tapered.
  • the dimensions of the lower portion 7' of the socket 7 and of the hole in the heel end portion 2 respectively are so selected and interrelated that the socket 7 cannot be pulled all through the heel end portion 2 by the spring even when no tread part stem 5 has been received in the central, square socket cavity 6.
  • the mechanismparts cannot be inadvertently separated and get lost, but on the other hand they can easily be removed intentionally by screwing the sleeve nut 9 off the top end 7" of the socket e.g. for replacement of a broken spring or the like.
  • a suitable selection of the taper of the lower portion 7' of the socket 7 will ensure a very reliable retention of the tread part stem 5 even with a moderately powerful spring 11, and since the tread part stem 5, the socket 7 and the hole of the heel end portion 2 are all of unround cross section, the tread part 4 is effectively prevented from turning relative to the heel end portion 2 and thus also relative to the heel 1 proper, with which the heel end portion 2 is connected.
  • a suitable tool for instance a pin 13 (FIG. 1), is inserted through the tubular extension 3, i.e.
  • tread part 4 should, of course, be available for the consumers in various materials, e.g. in metal for outdoor use and in plastic for in-door use, and it will be readily understood that very little technical skill is required to effect a change or replacement whenever desired. If the tread part 4 has been so extensively worn down that the heel end portion 2 has also become worn, the latter may in most cases be flattened and reconditioned by grinding, provided, of course, that the wear has not been permitted to go too far.
  • the stem may be provided with transverse corrugations or quite simply with a rough surface.
  • the arrangement describe-d may be made in various sizes to suit various heel and shoe models.
  • the length of the tubular extension 3 can, of course, be varied to suit various heel heights. If the heel 1 proper is made of a material having the sufiicient strength, the tubular extension 3 may, if desired, be dispensed with and replaced by a suitable bore through the heel proper. It is furthermore possible to choose any other cross sectional shape than the square one for the tread part stem 5 and the lower portion 7 of the socket 7, the essential thing being that these parts must be unround to prevent an unintentional turning of the tread part relative to the rest of the heel.
  • a shoe heel arrangement particularly for ladies shoes, and of the type including an exchangeable tread part having an upwardly projecting stem of unround cross section and a sleeve-shaped lower heel end portion which is rigidly connected to the rest of the heel and in which said stem of the tread part is adapted to be received and retained, said arrangement comprising a spring-actuated socket member which is axially slidable within said sleeveshaped heel end portion and which in its lower end has a cavity adapted to receive and grip said unround stern of the exchangeable tread part, the cavited lower end portion of said socket member being axially slotted and having an unround outer cross section gradually increasing in size towards the tread part, and said heel end portion having a lower mouth matching said slotted socket end portion in cross section and tapering inwardly in such a manner that, when said spring is pulling said socket member inwardly in said hole, the stem of the tread part received in said socket cavity will be grasped and retained therein by wedge action.
  • a shoe heel arrangement wherein a nut is removably attached to a threaded top end of said socket member and wherein said spring is mounted under compression between said nut and a shoulder on said heel end portion.
