CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of U.S. patent application Ser. No. 11/976,104, filed Oct. 22, 2007, which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION The present invention relates to an apparatus that provides an easy and quick method of fastening a shoe.
BACKGROUND OF THE INVENTION The conventional means of fastening a shoe with laces that needed to be tied is difficult to operate for many people with disabilities or for people that have difficulty bending over to access the instep of the shoe. Many solutions for fastening shoes that do not utilize laces instead include buckles or straps with a hook-and-loop fastening system, commonly known as Velcro®. However, in some shoes, such as sneakers, the strap closure does not look attractive. In addition, many users do not like to wear shoes that they perceive to be specially made for the handicapped, and many users simply prefer the look of the conventional lacing system.
U.S. Pat. Nos. 4,081,916 to Salisbury, U.S. Pat. No. 4,414,761 to Mahood, and U.S. Pat. No. 5,027,482 to Torppey, respectively, disclose methods that combine laces with a hook-and-loop fastening system. A series of parallel laces that extend through the eyelets in the shoe flap on one side of the shoe-access-opening are attached to an elongated closure flap having hook-and-loop elements on its underside. In Mahood, the laces are secured beneath those same eyelets, and in Salisbury and Torppey, the laces are secured to the eyelets in the other shoe flap. Pulling the flap across the shoe-access-opening towards the other side of the shoe-access-opening tightens the shoe, and the closure flap is secured to the shoe via mating hook-and-loop elements on the upper surface of the other shoe flap. One drawback to all these systems is that the elongated flap affects the design and the appearance of the shoe, making the shoe look cumbersome. Another drawback is that, in all these systems, the laces lie across the shoe-access-opening, not in a criss-cross pattern, and thus do not have the appearance of a traditional lacing system.
U.S. Pat. No. 6,941,683 to Freed discloses a lacing system for a shoe that also combines laces with a strap, and is based on one elongated lace loop that forms four lace segments that extend from a strap on one side of the shoe, through several lace openings on that side's shoe flap, and criss-cross each other over the shoe-access-opening. Alternatively, the one elongated lace loop forms two lace segments that extend from a strap on each side of the shoe, through several lace openings on both shoe flaps, and criss-cross each other over the shoe-access-opening. When the straps are pulled, the multiple lace segments move through all the eyelets and tighten the shoe-access-opening.
One major drawback to U.S. Pat. No. 6,941,683 is that it does not offer a solution to shoes with fewer than four pairs of eyelets, since this system requires at least three middle lace segments, and at least two bottom lace segments that criss-cross the shoe-access-opening. In addition, the plethora of lace segments criss-crossing over one another lends the show a cluttered and messy appearance. Another drawback is that this system is susceptible to high friction, which is caused by the configuration of the lace system, wherein some lace segments extend from the eyelets in a narrow angle, increasing the pressure and friction between the laces and the eyelets. The high friction makes it difficult to pull the lace through all the eyelets and prevents some lace segments from moving freely, resulting in shoe-access-opening that may not be tightened evenly, and may lead to laces tearing or wearing out more frequently.
SUMMARY OF THE INVENTION It is an object of the present invention to provide for a low friction apparatus for fastening a shoe that can be easily tightened by the user.
It is further an object of the present invention to provide for an apparatus for easily fastening a shoe that can be used by people with difficulties fastening and tying a conventional lacing system.
It is further an object of the present invention to provide for an apparatus for fastening a shoe, which can be applied to shoes with different number of eyelets.
It is another object of the present invention to provide for an apparatus for fastening a shoe, wherein the bottom element of the shoe-access-opening has the general appearance of a shoe with conventional lacing system.

It should be also noted that, while FIG. 1 shows the first side of the shoe access opening as adjacent to the outside of the shoe, and the second side of the shoe access opening as adjacent to the inside (or arch side) of the shoe, one skilled in the art will recognize that the references herein to first side and second side are merely for convenience of reference and that the disclosures herein apply equally where the second side is adjacent to the outside of the shoe and the first side is adjacent to the inside (or arch side) of the shoe.
The shoe comprises an adjustable gap in the instep area, which is used as the shoe-access-opening for tightening and loosening the shoe on the wearer's foot, including first side 2, second side 3, bottom side 4, and open top side 5.
In the embodiment shown in FIG. 1, the second side of the adjustable gap comprises two openings, and the first side comprises one opening. Examples for such openings are holes, eyelets, buckles and loops.
Elements 6 and 9 illustrate two parts of a fastener, wherein a first fastener element 6 is attached to the first side of the shoe, and a second fastener element 6 is attached to the laces, as described below. According to a preferred embodiment of the present invention, the two fastener elements 6 and 9 comprise two mating elements, such as clips, buckles, snaps, buttons or a hook and a loop system (such as Velcro®), for locking the two elements to each other.
According to a preferred embodiment of the present invention, two laces 7 and 8 each are attached at their proximal ends to second fastener element 9. FIGS. 2 and 3 illustrate an example of the attachment of laces 7 and 8 to second fastener element 9, which allows the user to adjust the usable length of the laces according to the wearer's foot size. FIG. 2 shows the bottom of second fastener element 9, wherein the two laces are threaded through holes defined in fastener element 9, and wherein the usable length of each lace can be adjusted. Once the desired usable lace length is attained, each lace is affixed to second fastener element 9, for example by being looped twice through the holes and tied with a knot, as illustrated in FIG. 3.
The two laces 7 and 8 extend from second fastener element 9 to the second side of the adjustable gap. According to one embodiment of the present invention, as shown in FIGS. 1 and 4, the two laces 7 and 8 are threaded through eyelets in the second side of the adjustable gap.
