The present relates generally to a replacement system for shoelaces, and more particularly to an elastic shoelace substitute and method that effectively converts lace-up shoes into slip-on shoes.
The problems associated with lace-up shoes are numerous and well known to the shoe-wearing public. Shoelaces can be difficult to insert into shoes. They can suffer from breakage or knotting. They can become soiled easily, necessitating their removal, cleaning, and replacement. Their ends can become frayed. They can come untied easily, exposing the wearer to a tripping hazard. Identifying the appropriate size of shoelace for replacement purposes can be difficult.
For such a common and everyday article that virtually everyone has had some experience with, shoelaces pose an enormous number of relatively trivial problems. Those problems become more significant when viewed through the eyes of a person who has a mobility disability, a temporary injury, or another disabling condition that makes lacing up shoes difficult.
Various solutions to these problems have been proposed and are well known. The slip-on shoe is perhaps the most common; slip-on shoes obviate the problem of shoelaces by eliminating them entirely. However, slip-on shoes pose their own problems. Depending upon the size and shape of the wearer's foot, slip-on shoes may be too tight to put on easily or too loose to keep on easily. Moreover, slip-on shoes are not always readily available for purchase, especially in athletic varieties.
Another solution to the problem of shoelaces has been to replace them with an alternative connection method, such as through hook-and-loop strap connections, buckles, or zippers. Each of these methods also pose their own problems, such as lack of availability, or merely replace one problem associated with laces with a similar problem. For example, both laces and buckles require fine motor control.
Moreover, these alternative methods may be deemed unattractive or unfashionable.
Additionally, none of these alternative methods have heretofore been available to retrofit existing shoes. A person who develops a back condition that prevents him or her from readily bending over to tie shoelaces might be faced with the necessity of replacing all of his or her shoes with non-tying models.
What is needed is a system for binding up shoes that replaces and approximates the look of conventional shoelaces, that avoids the myriad problems associated with shoelaces, and that can retrofit existing lace-up shoes.
In accordance with the aforementioned and other needs, the present invention includes a shoelace substitute for approximating the look and function of a shoelace in a shoe. The shoelace substitute includes a length of elastic material that has first and second ends. At each of the ends, the elastic material is provided with a barb, which has been crimped around and contains the end of the elastic material to form a T. The barbs are sized so that they can be inserted linearly through an eyelet of the shoe, whereupon they may be rotated in order to prevent them from being easily or casually withdrawn from the eyelet. Each end may be similarly inserted into corresponding eyelets to connect them via the elastic material, thereby approximating the look of a shoelace.
In another aspect, the present invention includes a shoelace system for approximating the look and function of a shoelace in a shoe. The shoelace system includes a number of shoelace substitutes, substantially as described above, with the number being selected to connect all, or substantially all, of the eyelets of the shoe. The group of shoelace substitutes together more fully approximates both the look and function of a fully laced shoe, but because the material joining or connecting the eyelets is elastic, the shoe may be easily “opened” to allow the insertion of the foot. The elastic action of the “laces” draws the eyelets back toward each other to provide a fit that is similar to that of a conventional shoelace, preventing the shoe from being easily dislodged from the wearer's foot.
The chosen elastic material may be substantially flat, in order to approximate the appearance of an athletic shoelace. In such an arrangement, the elastic material may be said to define a plane, and the barbs will be linearly oriented so as to be substantially orthogonal to that plane. Alternatively, the elastic material may be round, in order to approximate the appearance of a dress shoelace. In either case, the color and texture of the elastic material will be selected to match or coordinate with the shoe.
The present invention also includes a method of replacing a shoelace in a shoe, in which there are eyelets placed sequentially, in the usual manner, along left and right sides of the shoe upper along and above a tongue. The method includes a first step of providing a shoelace substitute substantially as described above, with the length selected so that the shoelace substitute traverses the distance between one of the eyelets on one of the sides and the corresponding eyelet on the other side, when the elastic material is somewhat elongated.
At the next step, one of the barbs of the shoelace substitute is inserted through one of the eyelets so as to put the barb between the eyelet and the tongue, and the barb is drawn into contact against the eyelet by the elastic action of the elastic member. The elastic material is then elongated to allow the next step, at which the other barb is inserted through the corresponding eyelet in a like manner.
Through this method, the eyelets are joined by the elastic material to approximate the look and function of the shoelace.
The present invention may also include the further step of repeating the above steps for each of the pairs of eyelets. As indicated before, the color and shape of the elastic material may be selected to coordinate with the type and color of the shoe.
Further features, embodiments, and advantages of the present invention will become apparent from the following detailed description with reference to the drawings, wherein:
Referring now to the drawings, the present invention is illustrated in an environmental view in
For example, when conventional laces are used, the shoe cannot be truly loosened except by increasing the amount of lace material between each pair of eyelets, an operation that requires the entire lace to be shifted through successive eyelets. Additionally, when a conventional lace is used to lace up the shoe, great care must be taken to keep the lace ends even as the shoe is laced, lest the wearer be left with one end longer than the other or, in an extreme case, run out of lace before all of the eyelets have been used.
In the present invention, however, the single-lace arrangement has been eliminated by providing the wearer with a set of shoelace substitutes 20, which link successive pairs of eyelets 14 to keep the eyelets 14 drawn somewhat together and to keep the wearer's shoe on his or her foot.
As can be seen in
The construction of the shoelace substitute 20 begins with the selection of a length of elastic material 22. This length will vary somewhat depending upon the particular shoe to which it will be applied, and different shoes may require a series of different lengths for various eyelets. An additional variable for consideration is the elasticity of the elastic material 22; depending upon the application, stronger or weaker elastic, or elastic having larger or smaller stretching capacity, may be indicated. For example, if what is contemplated is the conversion of a lace-up shoe to slip-on shoe for a person with back difficulties that make it difficult to bend over to lace shoes, then weak elastic with considerable stretching capacity may be chosen. Alternatively, if a firmer, tighter feel is preferred, stronger elastic might be chosen.
In order to form the shoelace substitute 20, once the length and strength of the elastic material segments 22 is selected, it is necessary to attach the barbs 30 to the ends 24,26. In a preferred embodiment, as can be seen in greater detail in
Once the elastic material segment 22 has been suitably arranged, the barb 30 may be crimped, in the direction of arrows A, around the end of the elastic material 22 to produce the generally cylindrical barb 30 shown in
In the embodiment shown in
Referring now to
Those skilled in the art to which the present invention relates will recognize that although it is generally preferred that the barbs be disposed under the eyelet, between the eyelet and the shoe, it would be equally possible to arrange a device according to the present invention with the barb on the outside of the eyelet. Moreover, although the embodiment in
In
The present invention thus presents notable advantages over conventional shoelaces, particularly including the advantage of making it easier for the wear to put on or take off shoes that use the present invention. Because the “laces” of the present invention are elastic, they may be stretched with relative ease to aid in putting them on, only to tighten automatically once the foot is in place. The effect is to convert a lace-up shoe to a slip-on shoe, while retaining the look of a lace-up shoe but not the difficulties associated with lacing shoes. Because there are no ends to tie, the user need not worry about tripping on an untied shoelace, and the shoelace substitutes of the present invention may be easily removed for cleaning and replaced.
In view of the aforesaid written description of the present invention, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended nor is to be construed to limit the present invention or otherwise to exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by any claims appended hereto and the equivalents thereof.
