PAOLETTA WILLIAM PETROU ATTORNEYS BACKGROUND OF THE INVENTION 1. Field oflnvention The present invention relates to shoehorns and more particularly to a laminated shoehorn that forms an integral part of a shoe.

2. Description of the Prior Art Various laminated shoehorns have been proposed for incorporation into a shoe as an integral part thereof. Early laminated shoehorns of relatively simple construction suffered from the disadvantage that they eventually resulted in a discomfort to the shoe wearer. In light of this eventuality, laminated shoehorns of relatively complex construction were fabricated. These subsequent laminates proved to be costly in production.

SUMMARY OF THE INVENTION An object of the present invention is to provide a laminated shoehorn characterized by upper and lower strata and adapted for incorporation into a shoe, either during or after manufacture, as an integral part thereof, The lower stratum includes a tab portion having flocking on one face for cushionable engagement with the heel of a persons foot and a glazelike surface on the opposite face for slidable engagement with the counter of the shoe. The profile of the rearward edge of the lower stratum, with the exception of the tab portion, and the rearward edge of the upper stratum substantially conform to the profile of the rearward edge of the shoe sock lining. The upper stratum and the lower stratum are secured to each other by an adhesive, the rearward edges of the strata being in registration. The laminate is bonded to the sock lining in such a way that the strata rearward edges are seated registerably with the rearward edge of the sock lining and the tab portion, lower stratum, and upper stratum define an integral shoehorn adapted for upward and downward movement within the shoe. The laminate is pulled up for engagement with the heel of a person's foot as it is about to be placed within the shoe and slides downwardly as the foot is inserted into the shoe, the flocking cushionably engaging the foot and the glazelike surface slidably engaging the shoe counter. The combination of lower stratum, tab portion, and upper stratum is such as to provide a comfortable, laminated shoehorn of simple construction.

The invention accordingly comprises the laminated shoehorn possessing the construction, combination of elements, and arrangement of parts that are exemplified in the following detailed disclosure, the scope of which will be indicated in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS. I and 2, there is shown a shoe 10 having a laminated shoehorn 112 made according to the invention and incorporated therein as an integral part thereof. Shoe 10 is comprised of an upper 14, an insole 16, an outsole 18, a heel 20, a counter 22 and a sock lining 24. The shoehorn is bonded to the sock lining in such a way that the laminate is adapted for upward and downward movement within the shoe. The shoehorn is pulled up for engagement with the heel of a persons foot as it is about to be placed within the shoe (FIG. 2) and slides downwardly as the foot is inserted into the shoe (FIG. 1).

Generally, as illustrated in FIGS. 3, a, and 5, laminated shoehorn 12, which is adapted for incorporation into the shoe during manufacture, comprises an upper stratum 26 and a lower stratum 28. The profile of upper stratum 26 defines a truncated oval which substantially conforms to the profile of the inner rearward portion of the shoe. Lower stratum 28 is provided with an integral tab portion 30 which extends from the rearward arcuate edge thereof. Tab portion 30 is narrowed at 32 so that it is more easily bent in this area. Flocking 34 is attached to the topside of stratum 28 and tab portion 30 for cushionable engagement with the heel of a persons foot. The underside of stratum 28 defines a glossylike or glazelike surface 36 which is adapted for slidable engagement with counter 22 as the foot is inserted into shoe 10. The profile of lower stratum 28, with the exception of tab portion 30, generally defines a truncated oval which substantially corresponds in shape to the profile of the rearward portion of upper stratum Upper stratum 26 and lower stratum 28 are bonded together in such a way that their arcuate rearward edges are registerable. In the preferred embodiment, upper stratum 26 is a pliant sheet material that is composed, for example, of a fibrous material such as fiberboard. As illustrated in FIG. 5, the forward edge of upper stratum 26 is skived at 35. For best results, each of lower stratum 28, and tab portion 30 is a pliant sheet material that is composed, for example, ofa leatherlike material such as leather, vinyl polymer, etc. Typically, the thickness of upper stratum 26 is in the range between 0.02 to 0.06 inch and the thickness of lower stratum and tab portion 30 is in the range between 0.01 to 0.04 inch. Accordingly, neglecting the thickness of flocking 34 which is typically in the range between 0.006 to 0.010 inch, the thickness of shoehorn 12 in the area that the upper stratum and the lower stratum are bonded together is in the approximate range of 0.03 to 0.10 inch.

Upper stratum 26 is bonded to sock lining 24 in such a way that the rearward edge of each are registerable and the shoehorn is adapted for upward and downward movement within the shoe, the sock lining acting as a hinge. As shown in FIG. 2, the shoehorn is pulled up for engagement with the heel of the foot as it is about to be placed within the shoe. As the foot is inserted into the shoe, the glazelike underside of lower stratum 28 slidably engages counter 44 and facilitates entry of the foot. After the foot is positioned within the shoe, tab portion 30 is bent upwards and substantially conforms to the inner rearward face of counter 22 and the arcuate rearward edges of the upper and lower strata abut counter 22, as indicated in FIG. ll, flocking 34 providing a comfortable support for the shoe wearer.

Referring now to FIGS. 6, 7, 8 and 9, there is shown a shoehorn 38 which is adapted for incorporation into a finished shoe as an integral part thereof. Shoehorn 38 comprises an upper stratum 40 and a lower stratum 42. The profile of upper stratum 40 defines an oval, the rearward edge of which substantially conforms to the profile of the inner rearward edge of the shoe. The underside of upper stratum 40 is provided with a fabric mesh 44 and a pressure-sensitive adhesive 46, fabric mesh 44 enhancing the cohesive bonding; properties of adhesive 46. As shown in FIG. 6, a web 50 having a silicone release coating on its top side is attached to adhesive 46 as a protective member.

Lower stratum 42 is provided with an integral tab portion 52 which extends from the rearward arcuate edge thereof. Tab portion 52 is narrowed at 54 so that it is more easily bent in this area. The profile of lower stratum 42, with the exception of tab portion 52, substantially conforms to the profile of the rearward edge of upper stratum 40. Flocking 56 is attached to the topside of lower stratum 42 and tab portion 52 for cushionable engagement with the heel of a persons foot. The underside of lower stratum 42 defines a glossylike or glazelike surface 58 which is adapted for slidable engagement with the shoe counter as the foot is inserted into the shoe. The underside of upper stratum 40 and the top side of lower stratum 42 are bonded to each other by means of adhesive 46 in such a way that their rearward arcuate edges are in registration. For best results, each of upper stratum 40, lower stratum 42, and tab portion 52 is a pliant sheet material that is composed, for example, of a leatherlike material such as leather, vinyl polymer, etc.

As previously stated, shoehorn 12 is adapted for incorporation into a shoe during manufacture and shoehorn 38 is adapted for incorporation into a finished shoe. In order to attach shoehorn 38 into the shoe, the user strips off web 50, whereby pressure-sensitive adhesive 46 on the underside of upper stratum 40 is exposed. The shoehorn is placed within the shoe in such a manner that the rearward edge of the sock lining and the rearward edge of lower stratum 42 are registerable, tab portion 52 being upturned and abutting the inner face of the shoe counter. The user presses the topside of the forward portion of upper stratum 40 having the exposed pressure-sensitive adhesive on its underside down onto the sock lining, whereby shoehorn 38 is permanently attached to the sock lining. Shoehorn 38 is used and functions in the same manner as described in connection with shoehorn 12.

Since certain changes may be made in the foregoing disclosure without departing from the scope of the invention involved, it is intended that all matter contained in the above description and depicted in the accompanying drawings be construed in an illustrative and not in a limiting sense.
