Abstract

An internal lacing system wherein a plurality of lace guides having rotatable rollers are strategically positioned throughout a shoe to facilitate the securing of the foot within the shoe. First and second elongated laces are internally channeled through the respective lace guides so as to enable a user to tighten the shoe by pulling on exposed second ends of the first and second laces thereby allowing the laces to roll along each respective roller positioned within each lace guide. Because the first ends of the first and second laces are fixed, the pulling on the second ends of the first and second laces will result in a reciprocating force about each lace guide thus securely tightening the shoe around the user's foot.

TECHNICAL FIELD

The present invention relates generally to footwear and, more specifically, to an internally laced shoe.

BACKGROUND ART

There are a multitude of known shoe and lacing designs for footwear. However, these known designs are deficient in light of the present invention. For instance, previous designs fail to adequately and comfortably secure a user's foot within the shoe. Traditional shoes have an upper central exterior lacing system wherein the lacing is usually channeled through a plurality of eyelets positioned generally on both sides of the center top of the shoe and in close proximity thereto. This type of design fails to provide adequate support by limiting the securing area to generally the upper portion of the foot. For instance, in sporting applications these traditional designs may be physically dangerous and reduce the athlete's performance by allowing the foot to slide or otherwise move within the shoe during use. In addition, because the lacing in traditional designs is exterior, undesired accidents including snagging on objects and tripping on lacing that becomes untied during use may result. Moreover, because of the dangers of the exposed lace of exterior-laced shoes becoming snagged on machinery and placing a user in dangerous positions, many companies forbid the use of these types of shoes in certain industrial applications. Additionally, the lacing of exterior-laced shoes is exposed to the shoes exterior environment and often results in premature wear.

Several attempts have been made to overcome some of these deficiencies. For instance, designs have been proposed wherein the lace system wraps around the heel portion of the shoe to provide a better means for securing the foot within the shoe. Examples of such designs may be found by reference to U.S. Pat. No. 5,775,006 to Breuner, U.S. Pat. No. 5,400,529 to Bell et al., U.S. Pat. No. 5,269,078 to Cochrane and U.S. Pat. No. 3,977,098 to Chalmers. However, these designs teach the use of heel lacing in boots and therein incorporate more complicated and/or bulky fastening means and thus, are not suitable for typical shoes, especially sporting shoes. Moreover, lacing systems that only wrap around the heel of the shoe do not provide maximum securing of the entire foot within the shoe.

In an attempt to solve some of the above-discussed deficiencies of exterior lacing, U.S. Pat. No. 5,269,078 to Cochrane discloses a partially internally laced shoe. However, the internal lacing only wraps around the heel of the shoe; traditional lacing is needed for the upper center of the shoe. Nonetheless, even with the dual lacing system, Cochrane fails to secure the entire foot within a shoe as adequately as provided by the present invention. Moreover, the exterior lacing of Cochrane remains susceptible to snagging and premature wear and tear.

An additional deficiency noted in previous designs is the need to utilize two hands to tie and/or secure the lacing in position. For many handicap individuals, traditional shoes can be difficult if not impossible to tie and/or adequately secure around the feet. Additionally, many professional and nonprofessional athletes and other users find it both interfering and time consuming to use both hands to retie traditional shoe lacing that may become easily untied during use. In an attempt to overcome these deficiencies designs have been proposed that allow one hand or finger tightening. An example of such a design may be found by reference to U.S. Pat. No. 4,130,949 to Seidel. Although Seidel discloses a one-pull tightening system, as with other previous deficient designs, Seidel's lacing system only tightens the upper center portion of the shoe and thus fails to adequately secure the entire foot within the shoe.

It is readily apparent that a new and improved internally laced shoe is needed that provides for a one-pull lacing system that wraps around the entire shoe and foot, including the heel, to provide means for more adequately securing the entire foot within the shoe. It is, therefore, to the provision of such improvements that the present invention is directed.

BRIEF SUMMARY OF THE INVENTION

In the first primary embodiments, briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages by providing an internally laced shoe that more fully secures the wearer's foot within the shoe.

The present invention, in a preferred embodiment, comprises a shoe, a plurality of lace guides, a buckle and lacing. More specifically, lace guides are positioned at a multitude of advantage points to maximize the tightening of the shoe around a wearer's foot. These advantage points in the preferred embodiment are along the upper center, bottom inside edge, bottom outside edge and heel of the shoe. Preferably two to eight lace guides are positioned along the bottom inside edge, two to eight along the bottom outside edge, two to eight along the upper center and one to three on the heel of the shoe. The lace is preferably one continuous generally elongated rectangular-shaped cloth, elastic or other flexible material having a first end and a second end.

The first end of the lace is sewn or otherwise secured internally near the toe of the shoe. The second end of the lace is channeled through each lace guide starting with the first bottom edge lace guide proximal to the first end of the lace, through the sole of the shoe and through the first bottom lace guide opposite the secured first end of the lace and then through the first lace guide of the upper center set. Next, the lace is channeled through the next adjacent bottom edge guide on the side of the shoe having the secured first end of the lace. This pattern is continued until the lace is channeled through the next to last (fifth) upper center lace guide, at which time the lace is wrapped around the heel of the shoe, through the heel lace guide, and back around through the last upper center lace guide. Upon exiting this last lace guide the second end of the lace is channeled through a fixed buckle and into a small slit positioned near the buckle to provide a means for hiding any excess lace. Alternatively or additionally, hook-and-loop fastener or other suitable securing means may be utilized to secure the lace in the desired position in lieu of the buckle. Preferably, the first, fourth and sixth upper center lace guides extend through apertures formed in the outside layer of the shoe and thus are the only externally visible lace guides. As such, the lace remains internal until it exits out of the sixth upper lace guide except for small portions that are externally visible near or at the first, fourth and sixth upper center lace guides.

Because of the strategically placed lace guides, a user simply pulls on the exposed second end of the lace thereby allowing the lace to roll along a roller positioned within each lace guide. Additionally, because the first end of the lace is fixed, the pulling on the second end of the lace will result in a reciprocating force about each lace guide thus securely tightening the shoe around the user's foot.

In a first alternate embodiment, an internal lacing system is disclosed wherein the lace guides are positioned internally in a generally diamond-shaped layout. There are preferably four lace guides each comprises preferably two rollers. The first lace guide is positioned generally in the upper centerline of the shoe near the toe area; the second lace guide is positioned generally on the left side of the shoe and in close proximity to the sole at approximately the middle of the shoe, lengthwise; the third lace guide is positioned generally on the right side of the shoe and in close proximity to the sole at approximately the middle of the shoe, lengthwise, and thus directly opposite the second lace guide; the fourth lace guide is positioned generally in the upper centerline of the shoe near the foot opening. The lace in this first alternate embodiment is generally two elongated cylindrical-shaped cords made from cloth or other flexible material. Each lace has a first end and a second end.

The first end of each lace is secured to a point or adjacent points, preferably, near the center of the diamond-shaped formation. The second end of one lace is first channeled through the third lace guide and over one of its rollers, then through the first lace guide and over one of its rollers, then through the second lace guide and over one of its rollers, then through the fourth lace guide and encircles one of its rollers, and then exits the interior of the shoe and is secured by a buckle positioned on the left side of the shoe near the fourth lace guide. The second end of the other lace is first channeled through the second lace guide and over its other roller, then through the first lace guide and over its other roller, then through the third lace guide and over its other roller, then through the fourth lace guide and encircles its other roller, and then exits the interior of the shoe and is secured by a buckle positioned on the right side of the shoe near the fourth lace guide.

Because of the strategically placed lace guides in the first alternate embodiment, a user simply pulls in opposite directions on the two exposed second ends of the two laces thereby allowing the laces to roll along the rollers positioned within each lace guide. Additionally, because the first ends of each lace is fixed, the pulling on the second ends of each lace will result in a reciprocating force about each lace guide thus securely tightening the shoe around the user's foot.

In a second alternate embodiment of the present invention, as with the preferred embodiment, lace guides are positioned along the upper center, bottom left edge, bottom right edge and heel of the shoe. However, with this embodiment, three lace guides are positioned along the lower left edge, two along the bottom right edge, six along the upper center and one on the heel of the shoe. An additional distinction from the preferred embodiment is that the lace is not channeled through the sole of the shoe; all of the lower left and lower right edge lace guides are positioned just above the sole of the shoe. The lace is preferably one continuous generally elongated rectangular-shaped cloth made from elastic or other flexible material having a first end and a second end.

The first end of the lace is sewn or otherwise secured internally near the toe of the shoe. The second end of the lace is channeled through each lace guide starting with the first bottom edge lace guide proximal to the first end of the lace and through the first lace guide of the upper center set. Next, the lace is channeled through the next adjacent bottom edge guide on the side of the shoe having the secured first end of the lace. This pattern is continued until the lace is channeled through the next to last (fifth) upper center lace guide, at which time the lace is wrapped around the heel of the shoe, through the heel lace guide, and back around through the last upper center lace guide. Upon exiting this last lace guide the second end of the lace is channeled through a fixed buckle and into a small slit positioned near the buckle to provide a means for hiding any excess lace. Alternatively or additionally, hook-and-loop fastener or other suitable securing means may be utilized to secure the lace in the desired position in lieu of the buckle. Preferably, the first, fourth and sixth upper center lace guides extend through apertures formed in the outside layer of the shoe and thus are the only externally visible lace guides. As such, the lace remains internal until it exits out of the sixth upper lace guide except for small portions that are externally visible near or at the first, fourth and sixth upper center lace guides.

In the second primary embodiments, briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages by providing an internally laced shoe that more fully secures the wearer's foot within the shoe.

The present invention, in a preferred embodiment, comprises a shoe, a plurality of lace guides, a buckle, a first lace and a second lace. More specifically, lace guides are positioned at a multitude of advantage points to maximize the tightening of the shoe around a wearer's foot. These advantage points in the preferred embodiment are along the upper center, lower inside edge, lower outside edge and heel of the shoe. Preferably one to eight lace guides are positioned along the lower inside edge above the sole, one to eight along the lower outside edge above the sole, two to eight along the upper center and one to three on the heel of the shoe. Preferably, the first and second lace are generally elongated rectangular-shaped cloth, elastic or other flexible material each having a first end and a second end.

The first end of the first lace is sewn or otherwise secured internally near the toe of the shoe. The second end of the first lace is channeled through the lower inside and outside lace guides and preferably at least two of the upper center lace guides starting with the first lower edge lace guide proximal to the first end of the first lace and then through the first lace guide of the upper center set. Next, the second end of the first lace is channeled through the next adjacent bottom edge guide on the side of the shoe having the secured first end of the first lace. This pattern is continued until the lace is channeled through the next to last upper center lace guide, at which time the first lace exits the interior of the shoe and is channeled and secured through a fixed buckle or by hook-and-loop fastener and into a small slit positioned near the buckle to provide a means for hiding any excess lace.

The first end of the second lace is secured within the shoe proximal to the heel of the shoe. The second end of the second lace is then wrapped around the heel of the shoe, through the heel lace guide, and back around through the last upper center lace guide. Upon exiting this last lace guide the second end of the second lace is channeled through a fixed buckle or by hook-and-loop fastener and into a small slit positioned near the buckle to provide a means for hiding any excess lace. Alternatively or additionally, hook-and-loop fastener or other suitable securing means may be utilized to secure the first and second laces in the desired position in lieu of the buckles. Preferably, the upper center lace guides extend through apertures formed in the outside layer of the shoe and thus are the only externally visible lace guides. As such, the first and second laces remain internal until they exit out of the shoe at their respective locations except for small portions that are externally visible near or at the upper center lace guides.

Because of the strategically placed lace guides, a user simply pulls on the exposed second ends of the first and second laces thereby allowing the first and second laces to roll along a roller positioned within each lace guide. Additionally, because the first ends of the first and second laces are fixed, the pulling on the second ends of the first and second laces will result in a reciprocating force about each lace guide thus securely tightening the shoe around the user's foot.

DETAILED DESCRIPTION OF THE PREFERRED AND ALTERNATE EMBODIMENTS

In first primary embodiments, referring now to FIGS. [0055] 14, device 10 in a preferred embodiment generally comprises shoe 20, lacing guide system 60, lace 102 and buckle 108. More particularly, lacing guide system 60 preferably comprises a plurality of lace guides 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94 positioned generally in three groups. Group A 61 comprises lace guides 62, 64, 66, 68, 70, 72 positioned generally near the top center of shoe 20 spaced apart along approximately a center line of tongue 28. Group B 81 comprises lace guides 74, 76, 78, 80, 82 positioned generally along the left side of shoe 20 in sole 22 and spaced horizontally apart. Group C 91 comprises lace guides 84, 86, 88, 90, 92 positioned generally along the right side of shoe 20 in sole 22 and spaced horizontally apart. An additional lace guide 94 is positioned generally near the center of heel 26. All lace guides except lace guides 62, 68 and 72 are internal and thus are not visible from the exterior of the shoe. Lace guides 62, 68, and 72 of Group A 61 protrude through apertures 96, 98 and 100, respectively, formed through the exterior layer of shoe 20.
[0056] Lace 102 is generally an elongated rectangular-shaped elastic, cloth or other flexible material having first end 104 and second end 106. First end 104 of lace 102 is fixably secured by sewing or other well-known means to the internal portion of the shell of shoe 20, preferably near the toe portion of shoe 20 at location 105. Second end 106 of lace 102 is first channeled through adjacent lace guide 74, through sole 22 and through lace guide 84. Next, second end 106 of lace 102 is channeled up to and through lace guide 62 positioned on the upper center of shoe 20 and then down to and through lace guide 76. The above pattern is repeated until second end 106 of lace 102 has been channeled through remaining lace guides 86, 64, 78, 88, 66, 80, 90, 68, 82, 92 and 70, sequentially. After being channeled through lace guide 70, second end 106 of lace 102 internally wraps around heel 26, through lace guide 94 and around through lace guide 72. At lace guide 72, second end 106 of lace 102 exits the shoe and becomes exterior. Second end 106 of lace 102 is then channeled through and secured by buckle 108, wherein buckle 108 is secured to the exterior of shoe 20 proximal to lace guide 72. To receive and secure second end 106 of lace 102 is hook-and-loop fastener 112 positioned in close proximity to the exit side of buckle 108. Alternatively or in addition, slit 110 is formed in close proximity to the exit side of buckle 108 and is dimensioned for receiving second end 106 of lace 102 and any excess lace.
Now referring to FIGS. [0057] 7-8, each lace guide 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94 comprises casing 206 and roller 200. Each roller 200 rotates about pin 206 that additionally serves to secure roller 200 within casing 206 by engaging an aperture or dimple within casing 206. Casing 206 is generally a four-sided rectangular box-like structure having two opposite opened ends. Each casing 206 is secured at the respective locations in shoe 20 by adhesive material, a securing strap extending through casing 206 and sewn to shoe 20, or by other well known means. Lace 102 extends through the opened ends and over or under roller 200. To allow lace 102 to rotate about the respective rollers 200, lace 102 is channeled over roller 200 in lace guides 62, 64, 66, 68, 70, 72 and 94, and is channeled under roller 200 in lace guides 74, 76, 78, 80, 82, 84, 86, 88, 90 and 92.
In use, because of the strategically placed lace guides [0058] 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, a user simply pulls on the exposed second end 106 of lace 102 thereby allowing the lace to roll along a roller positioned within each lace guide. Additionally, because the first end of the lace is fixed, the pulling on the second end of the lace will result in a reciprocating force about each lace guide thus tightening the shoe around the user's foot.
Referring now to FIGS. [0059] 9-11, first alternate embodiment 300 generally comprises shoe 320, lacing guide system 360, laces 310, 312 and buckles 362, 365. More particularly, lacing guide system 360 preferably comprises a plurality of dual lace guides 325, 330, 340, 350 positioned under the exterior layer of shoe 320 in generally a diamond-shaped formation. Lace guide 350 is positioned generally at the upper center of shoe 320 proximal to the exposed portion of tongue 328. Lace guide 330 is positioned generally at the upper center of shoe 320 proximal to toe area 334. Lace guide 325 is positioned generally on the left side of shoe 320 proximal to sole 322 and more specifically, in approximately the same vertical plane as lace guide 350. Lace guide 340 is positioned generally on the right side of shoe 320 proximal to sole 322 and more specifically, in approximately the same vertical plane as lace guide 350.
Lace guide [0060] 325 comprises casing 327 and rollers 322, 324. Rollers 322 and 324 rotate about pins 326 and 328, respectively, which additionally serve to secure rollers 322, 324 within casing 327 by engaging an aperture or dimple within casing 327. Note that lace guides 330, 340, 350 are identical to lace guide 325. Casing 327 is generally a four-sided rectangular box-like structure having two opposite opened ends. Each casing 327 is secured at the respective locations in shoe 320 by adhesive material, a securing strap extending through casing 327 and sewn to shoe 320, or by other well known means.
[0061] First end 314 of second lace 312 is sewn or otherwise secured at point 370 located generally near the upper center of shoe 320, and second end 390 of second lace 312 first is channeled through the opened ends of lace guide 325 and over roller 322. Next, second end 390 of second lace 312 is channeled through the open ends of lace guide 330 and over roller 332, and then channeled through the open ends of lace guide 340 and over roller 342. Second end 390 of second lace 312 is then channeled into the right side opening of lace guide 350, around roller 352, back out the right side opening and secured through buckle 362. Second end 390 of second lace 312 and any excess is inserted through slit 392 formed adjacent to buckle 362. First end 316 of first lace 310 is sewn or otherwise secured at point 372 located generally near the upper center of shoe 320, and second end 380 of first lace 310 first is channeled through the opened ends of lace guide 340 and over roller 344. Next, second end 380 of first lace 310 is channeled through the open ends of lace guide 330 and over roller 336, and then channeled through the open ends of lace guide 325 and over roller 324. Second end 380 of first lace 310 is then channeled into the left side opening of lace guide 350, around roller 354, back out the right side opening and secured through buckle 365. Second end 380 of first lace 310 and any excess is inserted through slit 382 formed adjacent to buckle 365.
In use, because of the strategically placed lace guides [0062] 325, 330, 340, 350, a user simply pulls on the exposed second end 380 of first lace 310 generally to the left and the exposed second end 390 of second lace 312 generally to the right, thereby allowing the laces to roll along a roller positioned within each lace guide.
