My invention lies in the field of shoes and relates to a unique method and apparatus for quickly and positively securing a laced shoe to the foot with a predetermined tension on the shoe's lace.
Background and Summary of the Invention
Conventionally a laced shoe employs a single elongated lace threaded from the bottom of the shoe's collar through two rows of equally spaced apart eyelets located on opposite sides of the shoe's tongue. The two ends of the lace are pulled tight and tied in a bow to secure the shoe to the foot.
Each time the shoe is removed, the two ends of the lace are untied and the lace is loosened from its tied position so that the shoe can be slipped off the foot.
Then when the shoe is to be worn, the lace is loosened between several of the eyelets to enable the shoe to be comfortably slipped onto the foot, the two ends of the lace are then pulled to take up the slack in the lace and the two ends are tied together.
Often times, especially with athletic or sportswear shoes used for running, tennis, basketball and other athletic events, the lace must be carefully adjusted to effect the proper tension of the tied lace and the shoe onto the foot. This takes time and requires an individual readjustment of the length of the lace between eyelets each time the shoe is put onto the foot.
My invention is uniquely designed to be attached to the laces of any footwear and it allows the user to tighten or loosen the shoe's fit over the foot in a single smooth motion. My invention which I call SNAPS.TM. thereby eliminates the present time-consuming need to adjust individual laces to achieve the necessary fit. While my invention may be used with most laced footwear styles, its primary market is in the sportswear field.
The SNAPS.TM. is a two-part clip with a hinge-like configuration and comprising a lower clip base joined at its front edge to an upper clip lever by a ball and socket type connection which closes with a swivel motion. A series of holes acting as eyelets are incorporated within both the clip base and clip lever which correspond with the eyelets on the shoe's collar. These holes allow the shoe lace to be threaded directly from the shoe's corresponding eyelets, thereby attaching and securing both the clip base and the clip lever to opposite sides of the shoe's collar.
In order to join the clip lever to the clip base, the clip lever and attached laces are mechanically transversed over the tongue of the shoe and the balled edge of the clip lever is inserted into the slotted edge of the clip base. The clip lever is then folded over, thereby taking up the lace slack, and secured by means of a male-female snapping mechanism such as a velcro flap on the clip base folded over and pressed onto a velcro patch on the clip lever. SNAPS.TM. is designed to be a one-handed operation.
The preferred velcro flap and patch serves as an additional safety measure against accidental disengagement. However, none of the lace tension is directly supported by the velcro flap.
The amount of tension required for SNAPS.TM. to perform its function is predetermined during the initial fitting, when the lace is fed through the clip base and the clip lever following the lace routing directions. The lace slack is quickly and conveniently removed when SNAPS.TM. is placed in its closed position.

Detailed Description of a Preferred Embodiment of the Invention
Referring first to FIG. 1 of the drawings, an athletic shoe 1 is shown with my two part fastening clip attached to shoe 1 by means of lace 2. My fastening clip comprises two rectangular and preferably convexly curved parts, clip base 4 and clip lever 5.
Each of clip base 4 and clip lever 5 contains three eyelets 4b and 5b respectively as shown in FIG. 1 spaced apart along the base or lever similar to the spacing between eyelets 1b on the shoe's collar on opposite sides of the shoe's tongue 1a.
One edge of clip base 4 is curved back upon itself to form an open faced elongated socket or slot 4a and one edge of clip lever 5 is enlarged to form an elongated cylindrical in cross section edge 5a designed to fit in hinged relation within the elongated slot 4a in clip base 4.
Attached to the edge of clip base 4 opposite slot 4a is a flexible flap 4c of hook and eye material such as velcro and mounted on the upper face of clip lever 5 away from its elongated edge 5a is a strip 5c of hook and eye material designed to interlock with the hook and eye material on flap 4c of clip base 4 after the two parts of the clip are joined together.
Although the lace 2 can be threaded into eyelets 1b on opposite sides of the shoe's tongue 1a and the eyelets 4b in the clip base 4 and in eyelets 5b in the clip lever starting from the bottommost eyelets 1b or from the uppermost eyelets 1b, preferably as shown in FIGS. 1 and 2 lacing begins by inserting the ends of lace 2 into the uppermost eyelets 1b with the midpoint of lace 2 spanning the space between the two uppermost eyelets 1b as shown in FIGS. 1 and 2.
Now pass the opposite ends of lace 2 from the bottom of eyelet 1b through that eyelet on the opposite side of tongue 1a and then through the uppermost eyelet of either clip base 4 of clip lever 5 as shown in FIG. 1.
Referring now to that end of the lace passed through the uppermost eyelet 4b, now thread the lace through the middle eyelet 4b in the clip base, then through the adjacent eyelet 1b on the same side of tongue 1a, then through eyelet 1b on the opposite side of the tongue, then through middle eyelet 5b of the clip base, then through the lowermost eyelet 5b, then through the adjacent eyelet 1b and finally from its top through the lowermost eyelet 1b on the opposite side of tongue 1a.
Referring now to the opposite end of lace 2 passed through the uppermost eyelet of clip lever 5, now thread the lace through the middle eyelet 5b of the clip lever, then through the adjacent eyelet 1b on the same side of tongue 1a, then across the tongue and through the eyelet 1b on the opposite side of the tongue, then through middle eyelet 4b of the clip base, then through the lowermost eyelet 4b, then through the adjacent eyelet 1b on the same side of the tongue, then diagonally across the tongue and from its top down through the lowermost eyelet 1b on the opposite side of the tongue.
The two ends of lace 2 are now tied together by knot 2a as shown in FIGS. 1 and 2. Knot 2a should be positioned with sufficient play or slack in the lace, as shown in FIG. 1, to permit the wearer of shoe 1 to comfortably slip his or her foot into the shoe. However, knot 2a should also be positioned so that when the two parts of the fastener clip are joined and locked together as shown in FIG. 2, the lace achieves the desired tension of the shoe on the wearer's foot.
FIGS. 3 through 7 illustrate the successive steps taken to join and then lock together clip base 4 and clip lever 5 from their positions shown first in FIG. 1 and finally in FIG. 2. With shoe 1 on the wearer's foot, the wearer grasps clip lever 5 and as shown in FIG. 4 pulls it transversely across the shoe's tongue and then as shown in FIG. 5 inserts elongated edge 5a of the clip lever into slot 4a of the clip base. Then as shown in FIGS. 5 and 6 the clip lever is pressed down onto the clip base resting against the shoe. Finally, flap 4c of the clip base is folded over and the two hook and eye surfaces pressed together to securely lock clip base 4 and clip lever 5 into the position shown in FIG. 7.
Other means such as male-female button snaps may be used to lock the two parts of my fastener clip together. Preferably the two parts of the clip are made of high density molded plastic material, but they may be made of metal. While I have shown clips with three eyelets in the base and lever, clips with as few as two eyelets or as many as five may be used with various sizes and types of shoes.
While I have illustrated and described a preferred embodiment of my method and apparatus for quickly securing a laced shoe to the foot, various changes and modifications will become apparent to those skilled in the art and the spirit and scope of my invention is limited only by the appended claims.
