Patent Application

This invention generally relates to shoe laces that do not have to be tied or adjusted.
People typically tie shoelaces to secure and fit shoes to their feet. The most common means to tie shoes is to use standard shoelace to tie two-loop or “Bunny Ear” method, in the following manner: Step 1: Pulling the separate laces, crossing them and then pulling one lace through a triangular opening while simultaneously pulling on the other lace, Step 2: Forming and maintaining the shape of two “bunny ears” (loops), Step 3: Crossing both loops forming a diamond shape opening, and Step 4: Completing a knot by pulling one.
This method, while common, has several drawbacks. First, knots that are created by using the “Bunny Ear” method can become undone, especially if not tightened properly, and can result in the laces dropping on the floor. This can create a tripping hazard for both the wearer and those around him or her. Second, using standard shoelaces to tie via the “Bunny Ear” method requires the wearer to tie the shoelaces on both feet each time he or she puts the shoes on, and also requires constant adjustment. Furthermore, children and adults, such as those with disabilities or those with arthritis may have relatively poor fine motor skills, and therefore may find it difficult and inconvenient to keep their shoelaces tied.
In view of the foregoing problems, there is a need for a simplified way to secure shoes of all types to the wearer's foot. Both adults and children can greatly benefit from such a device that allows the user to wear any shoe without the need to tie shoelaces and which does not present the risk of the shoelaces becoming untied and creating a tripping hazard.
Embodiments of the present invention provides such a device. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In one aspect, embodiments of the invention provide a shoelace system that includes an elastic shoelace having a first end and a second end, and a T-bar attachment attached to the first end. The T-bar attachment is rotatable such that the T-bar attachment anchors the first end of the shoelace to an eyelet of a shoe when the elastic shoelace is pulled through that eyelet. The shoelace system further includes a fastening bracket having one or more openings. Each of the one or more openings has a plurality of inward-facing projections for receiving the second end of the elastic shoelace. The fastening bracket secures the second end of the shoelace in place after the second end is threaded through the one or more openings of the fastening bracket.
In a particular embodiment of the invention, the T-bar attachment and fastening bracket are configured to be positioned on an inside portion of any eyelet such that the T-bar attachment and fastening bracket are not visible on the outside of the shoe after installation.
In certain embodiments, each of the one or more openings is substantially circular and each of the plurality of inward-facing projections points toward a center of its respective opening. In particular embodiments, the number of inward-facing projections ranges from eight to twelve.
In some embodiments, the fastening bracket has only two openings, while, in other embodiments, the fastening bracket has only three openings. Some embodiments of the fastening bracket have only one opening. In a further embodiment, the T-bar attachment has a portion that is at least partially cylindrical and configured to accommodate an end of the shoelace inserted into the at least partially cylindrical portion. The T-bar attachment may have another portion that is at least partially flat.
In certain embodiments, a thickness of the fastening bracket is no more than eight-hundredths of an inch. In other embodiments, a length of the fastening bracket is approximately two-thirds of an inch, and a width of the fastening bracket is approximately one quarter of an inch.
In another aspect, embodiments of the invention provide a shoelace system that includes an elastic shoelace having a first end and a second end, and first and second fastening brackets each with one or more openings. Each of the one or more openings has a plurality of inward-facing projections for receiving the first and second ends of the elastic shoelace. The first and second fastening brackets secure the first and second ends, respectively, of the shoelace in place after the first and second ends are threaded through the one or more openings of its respective fastening bracket.
In certain embodiments, the first and second fastening brackets are configured to be positioned on an inside portion of the eyelet such that the first and second fastening brackets are not visible on the outside of the shoe after installation. In other embodiments, each of the one or more openings in the first and second fastening brackets is substantially circular and each of the plurality of inward-facing projections points toward a center of its respective opening. The number of inward-facing projections may range from eight to twelve.
In some embodiments, the fastening bracket has only two openings, while in other embodiments, the fastening bracket has only three openings. Some embodiments of the fastening bracket have only one opening. In a particular embodiment, a thickness of the fastening bracket is no more than eight-hundredths of an inch. In a further embodiment, a length of the fastening bracket is approximately two-thirds of an inch, and a width of the fastening bracket is approximately one quarter of an inch.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
The shoelace system disclosed herein is made from only two parts in addition to the laces to make the system simple and easy for the user to install and use. As shown in
As shown in the schematic drawing of
More specifically, the fastening bracket 110 holds the second end 108 of the shoelace 100 in place at the last eyelet 106 of the shoe to be threaded, and prevents the shoelace 100 from coming out of this last eyelet 106. In this manner, the shoelace 100 is permanently held in place at the length desired by the user to allow for a secure fit and easy removal of the shoe. Like the T-bar attachment 102, the fastening bracket 110 is normally invisible once installed as it is typically positioned behind the eyelet 106 on the inside of the shoe, as illustrated in
Once the second end 108 of the shoelace 100 is threaded through the openings 112 of the fastening bracket 110, any remaining, unneeded portion of the shoelace 100 can be cut off and thrown away. It is envisioned that the T-bar attachment 102 and the fastening bracket 110 can be made of metal or plastic, though other suitably similar materials may be used.
In a particular embodiment of the invention, the thickness of the fastening bracket 110 is approximately five-hundredths of an inch. In a particular embodiment, the thickness of the fastening bracket 110 is no more than eight-hundredths of an inch. In this embodiment, the length of the fastening bracket 110 ranges from two-thirds of an inch to one inch, while the width is approximately one quarter of an inch. It should be noted that the term “approximately”, as used herein, means within plus or minus 20% of the nominal value.
The shoelace system of the present invention is made to look indistinguishable from conventional shoelaces, and the system is constructed to work well in virtually any type of shoe. However, the shoelace system of the present invention only needs to be installed onto the shoe one time.
The shoelace system disclosed herein will work on shoes with virtually any number of eyelets 106, though ideally, the system works best when the shoe has at least three pairs of eyelets 106. Even and odd numbered pairs of eyelets 106 will both work equally well, though the length of the elastic shoelace 100 may have to be adjusted depending on the number of eyelets 106. Once the shoelace system is installed onto the shoe, the elastic shoelace 100 makes it possible for the user to quickly and easily take the shoe on or off as needed without adjustment, re-fastening, or re-tying of the shoelace 100.
Additionally, as can be seen from
