United States Patent TOE-PROTECTOR FOR INFANTS SHOES Meyer Shusterman, Phoenixville, Pa.

Application October 25, 1954, Serial No. 464,469

1 Claim. (Cl. 36-72) This invention relates to a toe-protector for childrens shoes, and more particularly to a toe-protector, which permits its fitting on the shoe to be observed and closely regulated.

The protection of the toe portion of the shoes of crawling infants and children has long presented a problem. It is a matter of common experience that the toe portion, and particularly the upper surface thereof, of creeping childrens shoes may be worn and the shoes rendered useless or unsightly due to contact with the creeping surface, while the remainder of the body of the shoe is intact and undamaged. Inasmuch as childrens shoes in this age bracket are relatively costly, this waste of footwear is a matter of concern to many parents, particularly young parents in the relatively low income brackets.

In the past, a variety of toe-protectors'have been proposed, but without exception they have proved unsatisfactory. An adequate toe-protector must be low in cost, of a size capable of fitting over a plurality of size ranges of infants shoes, and yet be readily removable and also furnish a satisfactory fit, so as to permit the child to crawl or walk without tripping over his toes. Moreover, the toe-protector and shoe combination must have an attractive appearance, as the appearance of childrens garments and clothes is a matter of concern and satisfaction to their parents. The toe-protector should also be light in weight. Shoe protectors which cover the entire shoe are not desirable because they interfere with wearing comfort, preventing the childs foot from breathing.

Moreover, toe-protectors comprising an upper having straps passing below the sole are unsatisfactory because the resulting differences in elevation on the flat soles of the infants shoe hinders their wearing comfort.

The use of woven or knitted fabrics or leather for toe or shoe-protectors, while perhaps advantageous for use in shoe-protectors for adults, is not satisfactory for toe-protectors for crawling children, as the inherent weight of the material renders it unsuitable for this purpose.

This invention has as an object the provision of a toe-- protector for infants shoes, which may be worn without discomfort to the child.

This invention has as a further object the provision of an inexpensive toe-protector, which may be used on a variety of infants shoe sizes, with an excellent fit.

Further objects of the present invention will become apparent upon reading the following specifications and referring to the accompanying drawings, in which similar characters of reference represent corresponding parts in each of the several views.

Figure 7 is a longitudinal sectional view through the axial center line of the embodiment shown in Figure 5.

Referring initially to Figures 1 to 4, the embodiment of the toe-protector of the present invention shown therein is designated 10. The body of the toe-protector is designated 11 and is formed from a thin, flexible, light hardwearing plastic, preferably a transparent plastic, polyethylene, a polymer of ethylene, made by Bakelite Co., having a thickness of about .035 to .060 inch is preferred, although other thin, pliable hard-wearing light plastics may be used, such as Vinylite, a polymer of vinyl chloride, made by Monsanto Chemical Corp., or nylon 3001, a polymer of hexamethylenediamine and adipic acid, made by E. I. Du Pont, may be used. The plastic may be tinted or translucent; however, the nature of the plastic should be such that the outline of the shoe may be observed from above or below when the toe-protector is operatively mounted. Rigid plastics, such as polystyrene, are not satisfactory for my toe-protector.

In the embodiment shown in Figures 1 to 4, the toeprot ector body 11 is cast'in one piece of the same transparent plastic.

The sole 12 is not of constant thickness but is some 25 percent thicker at its tip portion, than at its rear portion 14, tapering gradually to increased thickness from rear to tip. The free edge of rear portion 14 may be straight, as shown in Figure 3 and is located proximate the front of the instep.

The upper 15 is preferably also constructed so that its front portion is some 25 per cent thicker than its rear portion, the thickness increasing gradually from rear to front. The rear free edge 16 of upper 15 is welted or beaded providing greater strength.

As shown in the drawings, the seam-like edge 17 between the upper 15 of the toe-protector body 11 and the sole 12 thereof, extends or projects in the plane of the sole, a small distance, such as about .020 to .060 inch, beyond the joinder of the upper 15 and the sole 12. Outwardly projecting seamlike edge 17 furnishes great strength to the toe-protector when the infant-user crawls with the tips of his shoes perpendicular to the floor, without interfering with walking. Moreover, the increased thickness at the forward part of the toe-protector likewise furnishes the maximum protection in the region of greatest wear. Due to the natural tendency of the front part of infants shoes to turn upwardly, and the relatively small thickness of the toe-protector, this increased thickness does not interfere from the infants walking pattern.

The retention strap 18, made of elastic fabric or the like, may be secured to the body of the protector 11 by being looped through openings 19 in the rear of upper 15. Strap 18 is split and includes a buckle 20 permitting the size of the strap to be adjusted. A bell 21 may be secured, as by stitching to the rear of elastic strap 18. This bell 21 advises the infants parents as to its location.

I have found that by using a retention strap of adjustable size, three or four sizes of toe-protectors will cover the entire range of crawling infant shoe sizes. Inasmuch as the outline of the shoe may be seen through the upper 15 of the toe-protector body -11, the toe-protector may be operatively mounted on the shoe, as shown in Figures 2 and 3 with the rear of retention strap 18 slipped over the back of the shoe, and the toe of the shoe retained in the cavity within toe-protector body 11.

In the embodiment of the toe-protector shown in Figures 5, 6 and 7, the toe-protector 30 is made of two plastic components, the upper 31 is made of relatively pliable transparent and somewhat flexible plastic, such as polyethylene, Vinylite or nylon 3001 As shown in Figure 7, the upper may be appreciably thicker, such as about 25 per cent thicker at the front than at the rear. The sole 32 may likewise be appreciably thicker, such as about 25 per cent thicker at the front than at the rear. The sole 32 in the illustrated embodiment is opaque and may be made of difierent plastic than the remainder of the toe-protector; or of the same plastic but dyed differently.

The upper 31 and the sole 32 are joined together as by welding or the like. A projecting margin 33 of the sole 32, extends beyond the outer surface of the upper 31 a small distance, such as .020 to .060 inch, and furnishes great strength to the toe-protector, when the infant crawls with the tips of his shoes perpendicular to the floor. The rear edge 34 of upper 31 is beaded for strength and ease of fit.

The retention strap 35 is integral with upper 31, and includes a buckle 36 having a tongue 37, mating with a length of the strap having a series of perforations through which the tongue may pass. The perforations are closely spaced and due to the flexible properties of the plastic strap, an accurate fitting of the toe-protector on the shoe may be achieved. A bell 38 may be secured to the rear retention strap 35.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

I claim:

An infants shoe toe protector comprising an open end upper and a sole integrally formed of flexible plastic and constructed and arranged for extending over the toe portion of an infants shoe, a portion of said sole projecting beyond the outer surface of said upper for a small distance in the frontmost portion of the toe protector, the thickness of the sole diminishing from front to rear so that when said toe protector is mounted upon an infants shoe the rearmost portion of the sole of the toe protector is adjacent the ball of the infants foot and substantially in the plane of the sole of the infants shoe, and a retention strap extending from the rear portion of the upper and projecting rearwardly above the plane of the sole.
