SAHAGUN INTERCHANGEABLE HEEL LIFTS Filed Aug. 19, 1963 INVENT OR JOSE MORENO .SAHAGUN BY mzmaw/w ATTORNEYS United States Patent 3,218,736 IYTERCHANGEABLE HEEL LIFTS Jos Moreno Sahagt'm, 643 Col. Chapalita, Guadalajara, Edo. de .lalisco, San Pablo, Mexico Fiied Aug. 19, 1963, Ser. No. 303,037 Claims priority, application Mexico, Mar. 4, 1963, 71,137 Claims. (Cl. 3634) The present invention is related to heel lifts that are fitted in the bottom of the heel of womens shoes in order to avoid damage to said heels by the friction against the ground and which, due to their wearing away in a relatively short period, must be replaced frequently. This replacement may be effected with great ease by a combination of manual means in only a few minutes since it may be carried out by anyone without the need to send the shoes to a repair shop; furthermore, it reduces the cost of the heel lifts since those embodying this invention may be more economical than the ones used presently.
Accordingly, it is a primary object of this invention to provide a novel heel lift for womens shoes which can easily be replaced and which provides reinforcement for the heels of such shoes.
Another object is to provide a novel hollow shoe heel and lift assembly therefor which act as a substantially integral unit.
Other objects will become apparent from the following discussion and the attached drawings wherein:
FIGURE 1 is an exploded side view of the shoe heel and heel lift assembly of this invention;
FIGURE 2 is a side view in elevation partially in crosssection of the lower shoe heel and removable lift assembly of this invention;
FIGURE 3 is a side view in elevation, partially crosssectioned, of the sleeve insert used in the assembly of FIGURE 2;
FIGURE 4 is a partially cross-sectioned side view of the heel lift of FIGURE 1.
Referring now to the drawings wherein FIGURE 1 illustrates the novel shoe heel 20 and removable lift assembly of this invention, heel lift 10, as best shown in FIGURE 4, is provided with a solid base 12 having an abutment face 18 with a hollow, upstanding, noncylindrical attachment post 14 fixedly mounted thereon. Attachment post 14 is preferably half-round as shown in FIGURE 1 and is provided with a threaded through passage 16 located at about one-third of its length from abutment face 18. Attachment post 14 is further pro vided with flared lugs 36 which may be firmly embedded in base 12. Lugs 36 are preferably pressure fitted into base 12 so that they exert an outwardly directed force on base 12 thereby improving the durability of the heel lift.
Heel 20 is also provided with a threaded passage 22 located intermediate the ends of heel 20 on front surface 26. Passage 22 is so spaced that when passage 16 is aligned therewith abutment face 18 firmly abuts heel end face 28. Heel 20 is further provided with a non-cylindrical bore 38 for receiving a sleeve 30.
Hollow sleeve 30 (FIGURE 3) reinforces heel 20 when fitted into bore 38. The bore of sleeve 30 is the same non-cylindrical shape as attachment post 14 and is dimensioned so as to receive post 14 therein. A threaded bore 32 for passing a screw through both sides of sleeve 30 is positioned so as to align with passage 22 in heel 20 as shown in FIGURE 2. Attachment post 14 and sleeve 30 may be constructed of any suitably ductile and strong material such as brass, aluminum and iron.
After the sleeve has been inserted, the heel lift may be easily attached to the shoe heel by inserting attachment post 14 in sleeve 30 and applying suitable pressure to lift base member 12 to drive post 14 into position so that it can be fastened by means of screw 24.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
What is claimed and desired to be secured by Letters Patent is:
1. An improved shoe heel and removable lift assembly comprising a heel body having a bore therein opening through its lower end face and intersected between its opposite ends by a screw receiving passage opening through the front surface of the heel; a rigid sleeve dimensioned to closely fit said bore suitably fixed therein, said sleeve having an axial through bore of non-cylindrical configuration in cross-section and being provided with oppositely aligned threaded bores disposed to be aligned with said screw receiving passage when assembled in said bore; a heel lift fixedly mounting an upstanding attachment post formed in cross-section to matingly fit said sleeve through bore and having a screw passage extending laterally therethrough in position to be aligned with said threaded bores of said sleeve when the heel lift base abutment face engages the lower end face of the heel; and a screw having a head adapted to abuttingly engage the front surface of said heel defining said screw receiving passage and a threaded shank adapted to threadedly engage at least one of said threaded bores of said sleeve.
2. The improved shoe heel and removable lift assembly recited in claim 1 wherein said axial through bore of said sleeve is of half-round configuration.
3. The improved shoe heel and removable lift assembly of claim 1 wherein said attachment post is fixedly mounted on said heel lift by means of flared lugs embedded in said heel lift.
4. A removable heel lift comprising a solid abutment member having an upstanding, hollow, non-cylindrical attachment post fixedly mounted thereon.
5. The heel lift of claim 4 wherein said attachment post is fixedly mounted to said heel lift abutment member by means of flared lugs.
