Definitions
- the present invention relates to heel reinforcing inserts and, more particularly, to thin stem plastic heels employing reinforcing structures that carry with them the heel lift.
- heel insert constructions that are particularly adapted for impact-stretchable plastic lift materials.
- the present invention is primarily directed, it being an object of the invention to provide a new and improved heel-reinforcing insert of the vabove-described character. Still another object is to provide -a new and improved heel-reinforcing insert of more general utility, also.
- the present invention contemplates a reinforcing heel insert comprising a hard metal dowel and the like, a frusta-conical cup provided with a cover rigidly secured to the lower end of the dowel, prong means rigidly secured to the cup within the same, and a frusto-conical lift member, preferably of resilient plastic, conforming to the shape of the inner walls of the cup and secured therewithin and to the prong means, the slant height of the lift member being greater than that of the cup in order to provide a frusto-conical projection of the lift member below the cup.
- Preferred constructional details are hereinafter presented.
- FIG. l of which is an isometric view illustrating the insert of the present invention.
- FIG. 2 is a longitudinal sectional view of the lower portion of the insert, constructed in accordance with a preferred embodiment of the invention and upon an enlarged scale.
- a reinforcing dowel insert of the general type described in the said copending application is illustrated at 11, as of hardened steel and the like, intermed-iately provided with ridge means 15 for driving into the walls of a recess 9 in the thin stem 5 of a plastic or similar heel 1.
- the recess 9 extends from the lift end 7 of the heel tread, up preferably almost to the heel seat 3.
- the ridge means 15 is shown in the preferred form of a plurality of blades, though continuous ridge means or other securing means may be employed; but in some cases, the ridge means 15 will extend to points representing a slightly greater diameter than the body of the dowel 11 and of slightly greater diameter than the inner diameter of the recess 9 in the heel stem 5', in order that the driving of the insert 11 into the recess 9 will secure the dowel against all possible longitudinal, circular or other movement therein.
- the longitudinally extending dowel 11 is provided at its lower end with a head structure 17 which is of diameter much larger than that of the ridges 15 and that is connected to a truste-conical cup 2, preferably of metal, such as steel.
- the frusto-conical cup 2 is shown provided vvith a top cover 4 containing a centrally disposed aperture 6 within which the head 17 may be secured by a swedging or other well-known riveting technique, as shown in FIG. 2.
- the head 17 becomes thus locked to the cover 4, with the lower portion thereof preferably being slit or segmented and expanded to form outwardly and downwardly extending prongs or projections 17', with a depressed central region 4 of the cover 4 locked between the upper portion of the head 17, that serves as a locking collar, and the prongs 17' within the cup 2.
- small locking indentations 8 may be formed to provide a unitary secured structure 11-2.
- preferably resilient plastic such as the urethanes and other impact-stretchable plastic materials, including some forms of nylon and the like, is molded or yotherwise secured, locking to the prongs or projections 17 and providing a substantially frusto-conical plastic lift 10 conforming to the shape of the inner walls of the cup 2 and secured therewithin.
- the slant height of the plastic lift 10 is made greater than that of the cup 2 in order to provide a frusto-conical resilient plastic projection 10' of the lift 10 extending below the lower edge lof the cup 2.
- the lower portion 10 of the plastic lift preferably protrudes outwardly at the bottom edge of the cup 2 to continue as an in-line extension of the outer conical surface of the cup therebelow.
- a reinforcing heel insert comprising a dowel, a frusto-conical cup having a cover with an aperture therethrough, said dowel extending through said aperture and having a locking collar at the upper surface of said cover and depending prong means at the lower surface of said cover, said collar and said prong means gripping said cover therebetween to secure said dowel to said cup, and a frusto-conical lift member conforming to the shape of the inner walls of the cup, secured in said cup to the prong means, and adhered to said inner walls, the slant height of the lift member being greater than that of the cup in order to provide a frusto-conical projection of the References Cited by the Examiner lift member below the cup.
