Adjustable Shoelace Fastener and Method of Use

Abstract

An improved method for fastening shoes with shoelaces having a first end and an opposing second end includes a spanning member having a hole to accommodate the first end, and a slot preferably sized for an interference fit with the second end. The first end is passed through the hole and knotted, preventing it from passing back through the hole. The second end is pulled to tighten the shoelace, knotted and anchored in the slot, maintaining the taut shoelace securely in place. With multiple holes and multiple slots, the tautness of a shoelace can be adjusted. The spanning member remains in place on a shoe when not in use, held by the knot in the first end. For convenience, a user may tie another knot in the second end, with a loop sized to receive a finger, for easily grasping the second end and sliding it into a slot.

DETAILED DESCRIPTION

[0023] The following description is presented to enable any person skilled in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention. Thus, the present invention is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0024] Referring to FIGS. 1 and 2, a fastening device 10 for fixing a shoelace 12 under tension is shown. The shoelace 12 is a single string or cord having a first end 14 and a second end 16. The first end 14 and the second end 16 are inserted into a spanning member 18 which holds them under tension. The spanning member 18 may be a substantially flat planar piece or may have a substantial thickness as shown. The spanning member 18 is defined by a perimeter 20 extending around the spanning member's 18.

[0025] One or more holes 22 extend through the spanning member 18 and are disposed inward of the perimeter 20, and one or more slots 24 are formed in the spanning member 18 extending inward of the perimeter 20. In order to secure the shoestring 12 in the spanning member 18, a knot 26 is tied near the first end 14. With the first end 14 prevented from passing through a hole 22 due to the knot 26, the shoelace 12 may be tightened and the second end 16 inserted into a preferred slot 24 and fixed in place. The second end 16 must also be knotted (not shown) to prevent the second end 16 from travelling back through the slot 24.

[0026] Although the slots 24 may take a variety of forms, including straight walled slots or V-shaped slots (not shown), in a preferred embodiment the slots 24 have a narrowed entrance 28 to prevent the second end 16 from exiting the slot 24, and may have an enlarged terminal end 30. The enlarged terminal end 30 also helps prevent the second end 16 from exiting the slot 24. To help with inserting the shoelace 12 into a slot 24, the slots 24 may include bevels 32 to provide a tapered entrance to assist with seating the second end 16.

[0027] Referring to FIG. 3, in a second embodiment 100 the spanning member 102 may have the holes 22 and slots 24 of the first embodiment, and include one or more opposing slots 104 on opposite sides of the perimeter 106 of the spanning member 102. Also shown in FIG. 3 is a loop 36 formed in the second end 16, which allows a user (not shown) to easily place the second end 16 in a slot 24 with only one finger (not shown). Since the loop 36 is larger in circumference than the shoelace 12, the loop 36 can be used in instances when a greater amount of tension in the shoelace 12 is required. The loop also can be used to release the second end 16 with just one finger.

[0028] Referring to FIG. 4, in a third embodiment of the fastener 200, the spanning member 202 may be elongated for installation on larger shoes 38, boots or similar footwear. In this embodiment, vertical slots 204 are shown at a distance from the hole 206. The vertical slots 204 receive the second end 16 from the front of the spanning member 202. Here the shoelace 12 is shown in an untied state to illustrate that the spanning member 202 may be permanently left on the shoe 38 so a user can secure and unsecure the shoelace 12 by simply affixing and removing the second end 16 from a vertical slot 204.

[0029] In this embodiment, as with the others, the spanning member 202 presents the vertical slots 204 on the lateral side 44 of the shoe 38 while presenting the hole 206 on the medial side 42 of the shoe 38. The shoe 38 can be more easily fastened because a user need not reach across the shoe 38 to reach the loop 36 (not shown) and place it in a vertical slot 204. A user can simply knot the second end 16 and place it in a vertical slot 204 as desired. Once the second end 16 is knotted, no further lace tying or knotting is necessary to put on and take off the shoe 38. If a user prefers to have the second end 16 on the medial side 42 of the shoe, the spanning member 202 may simply be reversed.

[0030] Referring to FIG. 5A, in the fourth embodiment, it may be desirable for the fastener 300 to fit either a right sided or left sided shoe. In this embodiment, in order for the spanning member 302 to effectively anchor on the shoelace 12 (not shown) in either orientation, holes 304 are disposed on both sides of the spanning member 302, with center slots 308 disposed between them. Preferably, the holes 304 and center slots 308 are arranged bilaterally, so a shoelace 12 can be placed under the same degree of tension regardless of the orientation of the spanning member 302.

[0031] Referring to 5B, the spanning member 300 is shown in side view having an arc allowing the spanning member to present two or more levels of tension to a wearer. First, the spanning member 300 may be installed complimentary to the shoe 36 (not shown), which provides a less flexible degree of tension on the shoelace 12 (not shown). Alternatively, the spanning member 300 may be installed so that the arc bends away from the shoe 36. In this manner, flexibility in the spanning member 302 allows the spanning member 302 to flex back and forth toward the shoe 36. This configuration is useful for instance in the case of joggers, to avoid pinching of the shoe 36 when running, increasing circulation and comfort for the wearer. Also shown in FIG. SB, the center slots 308 may have exaggerated tapered entrances 310 to make sliding the second end 16 into and out of the center slots 308 easier.

[0032] Referring to FIG. 6, in a fifth embodiment of the fastener 400, it is possible to use the spanning member 402 to reduce the amount of excess shoelace 12, effectively shortening the shoelace 12 by passing the first end 14 of the shoelace 12 through the hole 404 and also passing it through one or more angled slots 406 disposed at a distance from the hole 404. By having more of the shoelace 12 taken up by running the first end 14 through the angled slots 406, when the second end 16 is anchored in a non-angled slot 408 across the spanning member 402, more tension is placed on the shoelace 12.

[0033] Referring to FIG. 7, in a sixth embodiment, the fastener 500 includes a spanning member 502 having a generally oblong shape, and including an enlarged area 504 between the hole 506 and a side slot 508. The enlarged area 504 is a convenient location for affixing indicia 510 such as a brand logo, image, safety information, emergency information, or I.D. information. Because the spanning member 502 will typically be located at the top of the shoe 38 (not shown), any indicia 510 can be easily seen. Contemplated indicia 510 also include educational images for use on children's shoes, such as displaying ‘right’ or ‘left’, or identification information including an adult's phone number for example.

[0034] Referring to FIG. 8, in another embodiment, the fastener 600 may include a spanning member 602 having a perimeter 604 made in a predetermined decorative shape to make attractive and fanciful adornments for a shoe 38 (not shown). Although the exemplary embodiment is a round button, the spanning member 602 could be made having a more complex perimeter 604 pattern reflecting a particular theme, such as an animal, or character. In the illustrated embodiment, the hole 606 and a side slot 608 are shown incorporated into a disk shaped spanning member 602.

[0035] Having described the devices of the preferred embodiments, now their operation, function and use is discussed.

[0036] In order to secure shoes using the first embodiment fastener 10, The first end 14 of a shoelace 12 on a laced shoe 38 is inserted through the hole 22. A knot 26 is formed in the first end 14 so that it cannot pass back through the hole 22. Preferably, this operation is performed close to the shoe 38. With the first end 14 fixed in place, the shoelace 12 is drawn to a desired degree of tautness. The second end 16 is then knotted and placed in a slot 24. It may be desirable for a user to tie a loop 36 in the second end 16 so the second end 16 can simply be grasped by a user's finger. This also has the benefit of preventing the second end 16 from traveling back through the slot 24.

[0037] When a user desires to remove the shoe 38, the second end 16 can be simply slid out of the slot, allowing the shoelace 12 to be loosened. Because the spanning member 18 is held in place on the shoe 38 by virtue of the knot 26, which will not travel through the hole 22, the spanning member 18 can be left on the shoe 38 when not in use until it needs to be worn again. Also, because the knot in the second end 16 can be left in place, a user need not re-tie the shoelace 12 after initial installation.

[0038] In this manner, the fastener 10 is helpful for very young children, who can utilize the invention to secure their shoes without having to learn complicated tying techniques. The fastener 10 is also helpful for people with deficient motor skills, or anyone desiring to fasten their shoes using one hand, or even one finger. By not having to have extra lacing material, there is a cost savings to manufacturers, and users need not tie laces to prevent them from dragging on the ground.

[0039] To fasten a shoe 38 using the second embodiment fastener 100, a user has the option and may prefer sliding the second end 16 into the opposing slot 104 when convenient to do so. For fastening larger shoes, such as boots, the third embodiment fastener 200 may be used. In this embodiment, the spanning member 202 is arced to nest against the shoe 38. The vertical slots 204 make installing the second end 16 easier. To fasten a shoe according to the fourth embodiment fastener 300, the flexible arced spanning member 302 may be used. In this embodiment, the spanning member 302 may be placed so that it nests against the shoe 38 for a close fit, or it may be reversed. If reversed, flexibility in the spanning member 302 allows it to flex with movement, which is useful in activities like running to avoid pinching a user's foot at the top of the shoe 38.

[0040] To use the fifth embodiment fastener 400, a user passes the first end 14 through the spanning member 402 more than once, by inserting the first end through the hole 404 and also through the slanted slot 406 before knotting the first end 14. With more of the shoelace 12 taken up by the spanning member 402, when the second end 16 is knotted and inserted in the vertical slot 408, the shoelace 12 is prevented from dragging on the ground. When using the sixth embodiment fastener 500, the spanning member 502 is affixed in a similar manner, by threading the first end 14 through the hole 506 and knotting it, then knotting the second end 16 and placing it in the slot 508. This is done so in a manner placing the spanning member 502 up against the shoe 38 making the indicia 510 clearly visible. In a similar manner, the seventh embodiment fastener 600 is installed in the same way, placing the fancifully shaped spanning member 602 against the shoe 38 to present the decorative perimeter 604 shape to viewers.

[0041] The foregoing description of the preferred embodiments of the Invention are sufficient to enable one skilled in the art to make and use the invention. It is understood, however, that the detail of the preferred embodiments presented are not intended to limit the scope of the invention, in as much as equivalents thereof and other modifications which come within the scope of the invention as defined by the claims will become apparent to those skilled in the art upon reading this specification.
