Definitions
- the invention generally pertains to variable tension lacing systems for footwear. More particularly, the tension systems permit adjustment of selected zones of the footwear lacing system, to provide an improved fit and to prevent discomfort during use.
- some portions of the lace may be slack while other portions are taut which results in certain portions of the shoe being tighter around certain sections of the foot, particularly the ankle portions which are closer to the lace ends. This can cause discomfort and may adversely affect performance when the wearer is involved in a sports activity.
- Certain sports footwear such as ski boots, use tightening mechanisms that include buckles that clamp together to tighten the boot about the foot.
- Such systems typically use three or four buckles positioned about the tongue area of the boot, and can be quickly clamped to tighten and unclamped to loosen the boot about the foot.
- Such systems isolate the closure forces about the immediate area of the buckle which can be undesirable in many circumstances, such as when the wearer is engaged in a sport that requires an evenly distributed force line along the length of the foot.
- buckles tend to be uncomfortable if used on some types of footwear, such as soft boots, and thus are primarily used only on hard-shell type footwear such as ski boots.
- footwear lacing systems have been developed that include a lace or cable attached to a tightening mechanism.
- the lace is threaded through a series of opposing guide members positioned along the top of the foot and ankle portions of the footwear.
- the tightening mechanism operates to wind up the lace to tighten the shoe about the foot, and to wind out the lace to release tension.
- the lace and guide members have low friction surfaces to facilitate sliding of the lace through the guide members to promote the even distribution of tension across the footwear.

- the sport boot 10 generally is a snowboard boot or other sport boot that is tightened about a wearer's foot using the lacing system.
- the present invention will be described herein with reference to a snowboard boot, it should be understood that the invention can be used with a wide variety of footwear.
- the boot 10 includes an upper 2 that includes a toe section 4 , a heel portion 6 , and an ankle portion 8 that surrounds the wearer's ankle.
- An instep portion 12 of the upper is located in between the toe and ankle areas.
- the boot upper includes two opposed closure edges 14 and 16 that partially cover a tongue 18 .
- the upper may be manufactured from any of a wide variety of materials known to those skilled in the art. For example, some snowboard boots are typically made of soft leather that conforms to the shape of the foot of a wearer. For other types of shoes or boots, the upper may be manufactured of hard or soft plastic, rubber or of a composite material. Many other types of materials could also be used.
- a lacing system 20 includes a lace or cable 22 , a tightening mechanism 24 , cable guide members 26 , stop devices 40 and lace cross guides 30 .
- the cable 22 may be tensioned to draw the closure edges 14 and 16 toward each other, to tighten the boot around the foot.
- the tongue 18 extends rearward from the toe section 4 , and is preferably made of a soft material such as leather.
- the tongue may be provided with a low friction top surface to facilitate sliding of the closure edges and laces over the top of the tongue when the lace is tightened or loosened. Such a low friction surface may be applied to the tongue, or may be integral with the tongue.
- the cable 22 can be threaded in a crossing pattern along the midline of the foot between the two generally parallel closure edges 14 and 16 .
- the cable guide members 26 and the lace cross guides 30 are made of a rigid and durable plastic material.
- the cable guide members are affixed to the closure edges of the upper in a known manner, such as by stitching, rivets, or adhesive.
- the lace cross guides 30 may also be affixed to the tongue 18 of the shoe.
- Each of the cable guide members 26 and the lace cross members 30 advantageously include smooth, low-friction channels that guide the cable therethrough.
- the cable guide members and cross members may be made of materials other than plastic or rubber, such as metal or a polymer or a composite material, and may include a lubricating coating on at least the inner channel surfaces to reduce friction and/or enhance the slideability of the laces passing therethrough.
- FIG. 1 shows two pairs of opposing cable guide members 26 , and two cross members 30 being used. However, other configurations are contemplated that include more or less such members, depending on factors such as the length of the footwear closure edges and the amount of tensioning control desired.
- the cable 22 may be one continuous loop that begins and terminates at the tightening mechanism 24 , and is threaded through the cable guide members 26 and the cross guide members 30 as discussed above.
- the cable 22 may be a low-friction cable that slides easily through the channels in the cable guide members and the cross guides.
- the cable may be formed of any polymeric or metal materials or a composite material, so long as such material exhibits sufficient axial strength and flexibility.
- solid core wires, solid core polymers, or multi-filament wires or polymers, which could be woven, braided, twisted or otherwise fabricated could be used.
- the outer surface of the cable could also be coated with a lubricous material such as Teflon® or nylon.
- the cable should be capable of withstanding break loads of at least 60 pounds, and preferably up to 150 pounds or more.
- the cable varies in length, wherein shorter or longer lengths are used depending on footwear size particular to the lacing system design.
- FIG. 2A is an enlarged, perspective view of a stop device 40 for use with a footwear lacing system such as that shown in FIG. 1 .
- the stop device 40 includes a stop head 42 that includes a stop front edge 44 , a stop rear edge 45 , and a stop base 46 .
- the stop base 46 has at least one associated stop tab 48 and includes ledges or finger surfaces 47 A and 47 B that allow a user to manipulate the stop tab as explained below.
- the stop device 40 also includes a stop guide 50 that includes a plurality of openings 52 .
- FIGS. 2B and 2C are perspective and side views, respectively, of the stop device 40 of FIG. 2A .
- the stop guide 50 includes at least one means 54 at a first distal end 53 for fastening the guide to the tongue 18 of an article of footwear.
- the means for fastening 54 is a rivet, but other fastening devices or fastening methods could be used to secure the first distal end portion 53 of the stop guide to the tongue.
- FIGS. 2B and 2C illustrate how the stop head 42 initially pivots in the direction of arrow A when a user disengages the stop tab 48 from an opening 52 of the stop guide 50 .
- the user pushes down on the finger surfaces 47 A and 47 B with his thumb and forefinger, for example, on either side of the stop guide 50 to pivot the stop head 42 and to urge the stop tab 48 away from the opening 52 .
- the stop head 42 and stop base 46 can be moved or adjusted by a wearer along the length of the stop guide 50 .
- the stop tab 48 can then be inserted into another of the openings 52 as desired to re-engage and immobilize the stop head 42 .
- more than one stop tab 48 could be associated with the base 46
- more than one fastening means 54 could be associated with the stop guide 50 .
- FIG. 1 shows two pairs of opposing stop devices 40 (four in all), one pair located in a first zone 13 in the upper cuff portion of the boot, and the other pair located in a second zone or in the instep area 12 in the lower cuff of the boot.
- the first distal end portions 53 of the various stop guides 50 are affixed to the tongue in locations beneath the eyestay, which in FIG. 1 are beneath the cable guide members 26 , and thus are not visible. If the system shown in FIG. 1 is tightened further, the tabs 5 and 7 in a third zone 15 will be urged toward each other. But the eyestay edges of the first zone 13 and second zone 12 will not move due to the stop devices 40 .
- the cross guides 30 include a base section 32 with a sleeve or underlying open area that covers and accommodates a second distal end portion 51 of the stop guides 50 (see FIGS. 2B and 2C ) of two opposing stop devices 40 .
- the base sections 32 cover the second distal ends 51 and form a barrier that limits movement of each stop head 42 in a direction towards the center line of the tongue 18 .
- the base sections 32 thus perform several functions including covering the second distal ends of opposing stop guides and restricting the movement of the stop heads 42 .
- the second distal ends 51 of the stop guides are free floating under the base section 32 , which permits the stop guides and stop heads to articulate to a slight degree when the boot flexes during use.
- the stop devices 40 are thus able to articulate somewhat about the cable guides members 26 during activity as the boot flexes. This flexibility allows for automatic adjustment as the wearer's foot moves about to change the angle between the upper and lower cuff.
- a user may adjust either the first zone 13 about the upper cuff of the lacing system 20 , or the second zone 12 about the lower cuff of the lacing system. Users that have a skinny or thin foot adjust the first zone before making other adjustments to ensure that the upper cuff is not too tight. Alternately, wearers that have relatively wide feet and skinny calves initially adjust the second zone to secure the stop devices 40 so that the lower cuff is not too tight.
- the user pulls on the finger tabs 47 A and 47 B (shown in FIGS. 2A to 2 C) to engage one or more stop tabs 48 in one or more openings 52 of the stop guide 50 for each stop device 40 .
- the tightening mechanism 24 then can be further manipulated to tighten the third zone 15 adjacent to the instep portion of the boot.

Description
- This application is a division of application Ser. No. 10/764,297 filed Jan. 23, 2004, the entire content of which is expressly incorporated herein by reference thereto.
- The invention generally pertains to variable tension lacing systems for footwear. More particularly, the tension systems permit adjustment of selected zones of the footwear lacing system, to provide an improved fit and to prevent discomfort during use.
- There are numerous systems that currently exist for tightening footwear about the foot of a wearer. The most common includes threading a lace in a zig-zag pattern through two parallel rows of eyelets that are placed on opposite sides of a tongue area of a shoe or boot. The shoe is tightened by pulling on opposite ends of the threaded lace to pull the two rows of eyelets together so that the closure edges of the cuffs are urged toward the middle of the foot, and then tying the lace ends in a knot to maintain the desired tension. There are a number of known problems with such traditional systems, including that the tightening force is not adequately distributed along the length of the threaded zone due to friction between the laces and eyelets. Thus, some portions of the lace may be slack while other portions are taut which results in certain portions of the shoe being tighter around certain sections of the foot, particularly the ankle portions which are closer to the lace ends. This can cause discomfort and may adversely affect performance when the wearer is involved in a sports activity.
- Conventional lacing systems are also typically difficult to untighten and/or difficult to readjust in order to redistribute tension because the wearer must loosen and adjust the lace from each of many eyelets. Simply untying the knot does not release the lace because friction between the lace and eyelets and between overlapping laces often maintains the toe portion and sometimes even much of the other areas above the foot in tension even after the knot is released. Consequently, a wearer often must loosen the lace from each individual eyelet, which can be tedious if the number of eyelets is high, for example, such as in an ice skate boot, a snowboard boot, or other high-performance sports footwear.
- Certain sports footwear, such as ski boots, use tightening mechanisms that include buckles that clamp together to tighten the boot about the foot. Such systems typically use three or four buckles positioned about the tongue area of the boot, and can be quickly clamped to tighten and unclamped to loosen the boot about the foot. However, such systems isolate the closure forces about the immediate area of the buckle which can be undesirable in many circumstances, such as when the wearer is engaged in a sport that requires an evenly distributed force line along the length of the foot. In addition, buckles tend to be uncomfortable if used on some types of footwear, such as soft boots, and thus are primarily used only on hard-shell type footwear such as ski boots.
- Other footwear lacing systems have been developed that include a lace or cable attached to a tightening mechanism. In one such system, the lace is threaded through a series of opposing guide members positioned along the top of the foot and ankle portions of the footwear. The tightening mechanism operates to wind up the lace to tighten the shoe about the foot, and to wind out the lace to release tension. The lace and guide members have low friction surfaces to facilitate sliding of the lace through the guide members to promote the even distribution of tension across the footwear. However, such systems cannot be used to isolate any specific region where a user may wish to increase or decrease tension. Further, as a wearer performs certain maneuvers, some sections of the system become constricted due to stress forces which causes discomfort. For example, snowboard riders wearing boots that include such a system have complained that the lace, which is typically a cable, tightens and causes discomfort across a lower portion of the tongue during flexion. A need thus exists for a tension lacing system that can be adjusted by a user to avoid discomfort that may occur when a shift in tension forces occurs during use.
- The invention relates to a footwear article that includes a footwear lacing system, a lace or cable and at least one stop device for preventing opposing closure edges of a footwear article from advancing towards each other. Advantageously, the stop device comprises a stop guide operatively associated with a first closure edge of the footwear article; and a releasable affixing member operatively associated with stop guide and affixable in at least two different selected positions with respect to the stop guide to selectively vary the advancement of the closure edges toward each other.
- In a first embodiment, the stop guide is fastened to a portion of the footwear article, and the releasable affixing member comprises a stop element having a stop head that is configured to be manipulated by a user to releasably secure the affixing member to a selected position across the length of the stop guide, and the stop head is operable to contact the first closure edge of the footwear article.
- In an advantageous implementation, a first distal end of the stop guide is configured for attachment to a tongue of the footwear article. The second distal end of the stop guide may be free-floating. In addition, a cross guide member may be included that is configured for attachment to the tongue. The cross guide member may include a base section with a sleeve to accommodate the second distal end of the stop guide, and a guide portion including at least one channel for guiding the lace or cable.
- In a beneficial variation, the stop device may include a stop guide with a plurality of openings, and the affixing member may include at least one stop pin for releaseably mating with a selected opening. The affixing member could include at least two stop pins, and the stop element may include a stop tab.
- In a preferred embodiment, the stop system includes a second stop device that includes a second stop guide and a second stop element having a second stop head, and a second releasable affixing member, wherein the second stop device is fastened to a portion of the footwear article that is adjacent to and opposite a first stop device such that the second stop head is operable to contact a second closure edge of the footwear article. In addition, the stop head may have a front surface that is shaped to complement the shape of a lace or cable guide member, wherein the guide member is associated with the closure edge of the footwear article and guides the lace or cable.
- In a variation, the stop guide includes a plurality of teeth, and the affixing member includes at least one tooth. In addition, the implementation may include a second stop element having a second affixing member that includes at least one tooth for releasably meshing with the teeth of the stop guide. In this case, first and the second stop elements include first and second stop heads configured to contact the first closure edge and an opposing second closure edge of the footwear article. The stop heads may be stop hooks that are shaped to securely contact the closure edges of the footwear article.
- Another implementation of the footwear article further comprises a stop device that includes a stop head having a first surface operable to contact the first closure edge of the footwear article, a tab connected to the stop head, and a fastener for releasably securing the tab in a selected position on the tongue area. The tab includes at least one adjustment hole for attachment to a tongue area of the footwear article.
- In an advantageous implementation, included is a second stop device comprising a second stop head having a surface operable to contact a second closure edge of the footwear article, a second tab connected to the second stop head and a second fastener for releasably securing the second tab in a selected position that is adjacent to and opposite a first stop device such that the second stop head is operable to contact the second closure edge of the footwear article. The second tab includes at least one adjustment hole for attachment to a tongue area of the footwear article.

FIG. 1 is a perspective view of asports boot 10 illustrating alacing system 20 that includes a first implementation of a stop device according to the invention. Thesport boot 10 generally is a snowboard boot or other sport boot that is tightened about a wearer's foot using the lacing system. Although the present invention will be described herein with reference to a snowboard boot, it should be understood that the invention can be used with a wide variety of footwear. - The
boot 10 includes an upper 2 that includes atoe section 4, aheel portion 6, and anankle portion 8 that surrounds the wearer's ankle. Aninstep portion 12 of the upper is located in between the toe and ankle areas. The boot upper includes two opposed closure edges 14 and 16 that partially cover atongue 18. The upper may be manufactured from any of a wide variety of materials known to those skilled in the art. For example, some snowboard boots are typically made of soft leather that conforms to the shape of the foot of a wearer. For other types of shoes or boots, the upper may be manufactured of hard or soft plastic, rubber or of a composite material. Many other types of materials could also be used. - In the implementation of
FIG. 1 , alacing system 20 includes a lace orcable 22, atightening mechanism 24,cable guide members 26, stopdevices 40 and lace cross guides 30. It should be understood that, as used herein, the terms lace and cable have the same meaning unless specified otherwise. Thecable 22 may be tensioned to draw the closure edges 14 and 16 toward each other, to tighten the boot around the foot. - The
tongue 18 extends rearward from thetoe section 4, and is preferably made of a soft material such as leather. The tongue may be provided with a low friction top surface to facilitate sliding of the closure edges and laces over the top of the tongue when the lace is tightened or loosened. Such a low friction surface may be applied to the tongue, or may be integral with the tongue. - As shown in
FIG. 1 , thecable 22 can be threaded in a crossing pattern along the midline of the foot between the two generally parallel closure edges 14 and 16. In this implementation, thecable guide members 26 and the lace cross guides 30 are made of a rigid and durable plastic material. The cable guide members are affixed to the closure edges of the upper in a known manner, such as by stitching, rivets, or adhesive. The lace cross guides 30 may also be affixed to thetongue 18 of the shoe. Each of thecable guide members 26 and thelace cross members 30 advantageously include smooth, low-friction channels that guide the cable therethrough. The cable guide members and cross members may be made of materials other than plastic or rubber, such as metal or a polymer or a composite material, and may include a lubricating coating on at least the inner channel surfaces to reduce friction and/or enhance the slideability of the laces passing therethrough.FIG. 1 shows two pairs of opposingcable guide members 26, and twocross members 30 being used. However, other configurations are contemplated that include more or less such members, depending on factors such as the length of the footwear closure edges and the amount of tensioning control desired. - The
cable 22 may be one continuous loop that begins and terminates at thetightening mechanism 24, and is threaded through thecable guide members 26 and thecross guide members 30 as discussed above. In addition, thecable 22 may be a low-friction cable that slides easily through the channels in the cable guide members and the cross guides. The cable may be formed of any polymeric or metal materials or a composite material, so long as such material exhibits sufficient axial strength and flexibility. For example, solid core wires, solid core polymers, or multi-filament wires or polymers, which could be woven, braided, twisted or otherwise fabricated could be used. The outer surface of the cable could also be coated with a lubricous material such as Teflon® or nylon. In use on snowboard boots, the cable should be capable of withstanding break loads of at least 60 pounds, and preferably up to 150 pounds or more. The cable varies in length, wherein shorter or longer lengths are used depending on footwear size particular to the lacing system design. -
FIG. 2A is an enlarged, perspective view of astop device 40 for use with a footwear lacing system such as that shown inFIG. 1 . Thestop device 40 includes astop head 42 that includes a stopfront edge 44, a stoprear edge 45, and astop base 46. Thestop base 46 has at least one associatedstop tab 48 and includes ledges or finger surfaces 47A and 47B that allow a user to manipulate the stop tab as explained below. Thestop device 40 also includes astop guide 50 that includes a plurality ofopenings 52. -
FIGS. 2B and 2C are perspective and side views, respectively, of thestop device 40 ofFIG. 2A . Thestop guide 50 includes at least one means 54 at a firstdistal end 53 for fastening the guide to thetongue 18 of an article of footwear. In this implementation, the means for fastening 54 is a rivet, but other fastening devices or fastening methods could be used to secure the firstdistal end portion 53 of the stop guide to the tongue. -
FIGS. 2B and 2C illustrate how thestop head 42 initially pivots in the direction of arrow A when a user disengages thestop tab 48 from anopening 52 of thestop guide 50. The user pushes down on the finger surfaces 47A and 47B with his thumb and forefinger, for example, on either side of thestop guide 50 to pivot thestop head 42 and to urge thestop tab 48 away from theopening 52. Once thestop tab 48 is disengaged from theopening 52, thestop head 42 and stopbase 46 can be moved or adjusted by a wearer along the length of thestop guide 50. Thestop tab 48 can then be inserted into another of theopenings 52 as desired to re-engage and immobilize thestop head 42. It should be understood that more than onestop tab 48 could be associated with thebase 46, and that more than one fastening means 54 could be associated with thestop guide 50. - Referring again to
FIG. 1 , the stop devices are shown in their fitted or stop positions. In the stop position, thefront edge 44 of thestop head 42 of each stop device abuts an outside wall of thecable guide members 26 and functions to resist movement of the closure edges 14 and 16 toward each other.FIG. 1 shows two pairs of opposing stop devices 40 (four in all), one pair located in afirst zone 13 in the upper cuff portion of the boot, and the other pair located in a second zone or in theinstep area 12 in the lower cuff of the boot. The firstdistal end portions 53 of the various stop guides 50 are affixed to the tongue in locations beneath the eyestay, which inFIG. 1 are beneath thecable guide members 26, and thus are not visible. If the system shown inFIG. 1 is tightened further, thetabs third zone 15 will be urged toward each other. But the eyestay edges of thefirst zone 13 andsecond zone 12 will not move due to thestop devices 40. - The cross guides 30 include a
base section 32 with a sleeve or underlying open area that covers and accommodates a seconddistal end portion 51 of the stop guides 50 (seeFIGS. 2B and 2C ) of two opposingstop devices 40. In this implementation, thebase sections 32 cover the second distal ends 51 and form a barrier that limits movement of eachstop head 42 in a direction towards the center line of thetongue 18. Thebase sections 32 thus perform several functions including covering the second distal ends of opposing stop guides and restricting the movement of the stop heads 42. It should be understood that, in this implementation, the second distal ends 51 of the stop guides are free floating under thebase section 32, which permits the stop guides and stop heads to articulate to a slight degree when the boot flexes during use. Thestop devices 40 are thus able to articulate somewhat about the cable guidesmembers 26 during activity as the boot flexes. This flexibility allows for automatic adjustment as the wearer's foot moves about to change the angle between the upper and lower cuff. - When first putting the boot on the foot, a user may adjust either the
first zone 13 about the upper cuff of thelacing system 20, or thesecond zone 12 about the lower cuff of the lacing system. Users that have a skinny or thin foot adjust the first zone before making other adjustments to ensure that the upper cuff is not too tight. Alternately, wearers that have relatively wide feet and skinny calves initially adjust the second zone to secure thestop devices 40 so that the lower cuff is not too tight. When the entire boot feels comfortable, the user pulls on the finger tabs 47A and 47B (shown inFIGS. 2A to 2C) to engage one ormore stop tabs 48 in one ormore openings 52 of thestop guide 50 for eachstop device 40. Thetightening mechanism 24 then can be further manipulated to tighten thethird zone 15 adjacent to the instep portion of the boot. -
FIGS. 3A to 3C depict another embodiment of astop device 60. In particular,FIG. 3A is an exploded perspective top view of thestop device 60 andFIG. 3B is a bottom view ofFIG. 3A . Thestop device 60 includes astop head 62 having a stopfront edge 63, a stoprear edge 64, and astop base 65. Thestop base 65 has twostop tabs second stop tab 67 is located beneath thestop head 62. Thestop device 60 also includes astop guide 70 that includes a plurality ofstop tab openings 72 and anaperture 74 for accommodating a fastening means, such as a rivet, nut and bolt arrangement, or screw. In use, thestop guide 70 is affixed at theaperture 74 to the tongue of an article of footwear so that it is stationary. The twostop tabs - Also shown in
FIGS. 3A to 3C is acable guide member 26 a that has a semi-circular shape. Thefront edge 63 of thestop head 62 is generally oval shaped to complement the shape of theinner wall 27, and will loosely fit into the inner wall of thecable guide member 26 a during use. Thus, when thestop device 60 is in its stopped position as shown inFIG. 3C , the stopfront edge 63 abuts theinner wall 27, but also includesopen areas FIG. 3B ) may be in the range of 0.25 inch to 3 inches. In a snowboard boot application, the length used is about 2 inches, and the length of the front wall of a stop head may be fabricated to be slightly less or to match. Different specific length combinations could be used to optimize the cable system, and one skilled in the art could easily choose a suitable size or length depending upon the type of footwear being used and/or depending on other considerations. -
FIG. 4A is a perspective view of asports boot 10 illustrating alacing system 20 a that includes two other implementations of a stop device. Thesport boot 10 may be a snowboard boot or other sport boot that is tightened about a wearer's foot by using the lacing system, and elements that are the same or similar to those shown inFIG. 1 are numbered the same inFIG. 4A . Thus, theboot 10 includes an upper 2 that includes atoe section 4, aheel portion 6, and anankle portion 8 that surrounds the wearer's ankle. Aninstep portion 12 of the upper is located in between the toe and ankle areas. The boot upper includes two opposed closure edges 14 and 16 that partially cover atongue 18. The upper may be manufactured from any of a wide variety of materials known to those skilled in the art. For example, as described above, the boot upper material may be of soft leather that conforms to the shape of the foot of a wearer, or may be manufactured of hard or soft plastic, rubber or of a composite material. - In the implementation of
FIG. 4A , thelacing system 20 a includes a lace orcable 22, atightening mechanism 24,cable guide members 26 a that are generally are “C”-shaped, stopdevices tongue 18 of the boot, and thecable 22 may be tensioned to draw the closure edges 14 and 16 toward each other, to tighten the boot around the foot. Thetongue 18 extends rearward from thetoe section 4, and preferably includes a low friction top surface to facilitate sliding of the closure edges and laces over the top of the tongue when the lace is tightened or loosened. - As shown in
FIG. 4A , thecable 22 can be threaded in a crossing or zig-zag pattern along the midline of the foot between the two generally parallel closure edges 14 and 16. Thecable guide members 26 a and the lace cross guides 31 may be made of a rigid and durable plastic material. The cable guide members are affixed to the closure edges of the upper in a known manner, such as by stitching, rivets, or adhesive. Each of thecable guide members 26 a and thelace cross members 31 advantageously include smooth, low-friction channels that guide the cable therethrough. The cable guide members and cross members may be made of materials other than plastic or rubber, such as metal or a polymer or a composite material, and may include a lubricating coating on at least the inner channel surfaces to reduce friction and/or enhance the slideability of the laces passing therethrough. - Although
FIG. 4A shows two pairs of opposingcable guide members 26 a, and twocross members 31 being used, other configurations are contemplated that include more or less such members, depending on factors such as the length of the footwear closure edges and the amount of tensioning control desired. - The
cable 22 may be one continuous piece of material that forms a loop that begins and terminates at thetightening mechanism 24, and is threaded through thecable guide members 26 a and thecross guide members 31 as discussed above. In addition, thecable 22 may be a low-friction cable that slides easily through the channels in the cable guide members and the cross guides, as described above. -
FIGS. 4B and 4C illustrate the relationship of astop device 80 to acable guide 26 a associated with theboot edge 16 in theupper zone 13 shown inFIG. 4A . Thestop device 80 includes astop head 82, atab 84 and a T-nut 86 which is used to fasten the stop device to thetongue 18. One of skill in the art would recognize that other fastening devices could also be used. In this implementation, thestop device surface 87 is shaped to complement the shape of theinner wall 27 a of thecable guide member 26 a. In particular, thestop device surface 87 is curved to match the curvature of theinner wall 27 a of the generally “C”-shapedcable guide element 26 a. In addition, thestop head 82 includes generally flat or straight top andbottom edges inner walls cable guide element 26 a. Thus, during use thestop head 82 mates with thecable guide 26 a. Thetab 84 includes twoadjustment holes 85 a and 85 b, but more or less holes could be used. In this implementation, a user adjusts the placement of thestop device 80 by using a T-nut in eitherhole 85 a or 85 b. In the implementation shown inFIG. 4A , a pair ofstop devices 80 are shown positioned to contact the closure edges on opposite sides of the tongue area of the footwear. If the user wishes a larger distance between the side edges in the upper zone, then she would place the T-nut through openings 85 a as shown inFIG. 4C for each of thestop devices 80. Alternately, if she would rather have the side edges closer together then she would useholes 85 b as shown inFIG. 4B for each of thestop devices 80. Any combination of adjustment holes could be used. -
FIGS. 4D to 4F illustrate another implementation of astop device 90, which is shown inFIG. 4A releaseably attached in thelower zone 12. Thestop device 90 includes astop head 92 having afront surface 93, arear surface 94, atop surface 98 and abottom surface 99. InFIG. 4D thefront surface 93 is contacting theinner wall 27 a (shown inFIG. 4B ) of thecable guide member 26 a, and the top 98 and bottom 99 surfaces are contacting theinner walls cable guide element 26 a. InFIG. 4E , theclosure edge 16 is pulled away from thestop device 90, and thestop head 92 has been rotated about apivot point 96. The pivot point is offset from the center axis of the stop head, and may include a T-nut fastener that affixes thestop element 90 to thetongue 18. When thestop device 90 is disengaged from thecable guide element 26 a as shown inFIG. 4E , it can be rotated about thepivot point 96 as shown by the circular arrow 91 into another position so that therear surface 94 is now facing theclosure element 26 a and thebottom surface 99 has switched positions with thetop surface 98. Therear surface 94 of thestop head 92 then may contact thecable guide element 26 a as shown inFIG. 4F . Since thepivot point 96 is offset from the central axis of the stop head, the user can adjust the relative distance between the stop head and theclosure edge 16. In the implementation shown inFIG. 4A , a pair ofstop devices 90 are shown positioned to contact the closure edges in alower zone 12 on opposite sides of the tongue area of the footwear. A user can adjust the distance between theside portions stop devices 90. - Referring again to
FIG. 4A , thestop devices boot 10. In the stop position, thefront edge 87 of the upper zone stop heads 82 abut an outside wall of thecable guide members 26 a, and one of thefront edges 93 or therear edge 94 of thestop devices 90 abut an outside wall of thecable guide members 26 a in thelower zone 12. Thestop devices FIG. 4A shows one pair of upper zone and one pair of lower zone stop devices (four in all), but additional pairs could be used, and the stop devices could be used in different combinations. - When first putting the boot on the foot, a user may adjust either the
first zone 13 about the upper cuff of thelacing system 20 a, or thesecond zone 12 about the lower cuff of the lacing system. Users that have a skinny or thin foot would adjust the first zone before making other adjustments to ensure that the upper cuff is not too tight. Alternately, wearers that have relatively wide feet and skinny calves initially adjust the second zone to secure thestop devices 90 so that the lower cuff is not too tight. When the entire boot feels comfortable, the user tightens the T-nuts on thestop devices 80 in the upper zone (seeFIGS. 4B and 4C ), and no longer rotates thestop devices 90 in the lower zone 12 (shown inFIGS. 4D to 4F). Thetightening mechanism 24 then can be further manipulated to tighten thethird zone 15 adjacent to the instep portion of the boot. - The stop guide devices shown in
FIGS. 2A to 2C, 3A to 3C and 4B to 4F may advantageously be made of a light and durable rigid or semi-rigid material. For example, the stop guide and stop head may be made of plastic, rubber, metal or a composite material that is able to withstand tension forces associated with tensioning the laces to secure the footwear to the foot, and forces that may occur when a wearer uses the footwear to maneuver down a slope. In addition, the stop head may be shaped to complement the shape of a cable guide member that is affixed to a closure edge, or may be of some other shape. -
FIG. 5A illustrates an alternate embodiment of alace tension system 100 for asports boot 120. The boot upper includes two opposed closure edges 114 and 116 that partially cover atongue 118. - The
lacing system 100 includes acable 122,tightening mechanism 124, opposingcable guide members 126, 127 (shown as dotted lines because these cable guide members are embedded in the upper) andcable guide members device 130. Thecable 122 is threaded in a crossing pattern along the midline of the boot over thetongue 118 between the two generally parallel closure edges 114 and 116. Thecable guide members device 130 include channels or passageways therethrough for accommodating thecable 122, and can be made of a rigid or durable plastics rubber or composite material. Although not shown, one or more cable guide members may also be present along the toe area of the boot. The cable guide members are affixed to the closure edges 114 and 116 in a known manner. Thecable 122 may be one continuous loop that begins and terminates at thetightening mechanism 124. The cable guide members and cable may be made of the materials described above. -
FIG. 5B is an enlarged front view of the cable lock-outdevice 130 shown inFIG. 5A . The cable lock-out device includes abase 131, twist-tighteningmechanisms 132, threadedtubes 134, stopbumpers 136 and channel guides 138. - Referring again to
FIG. 5A , the cable lock-out device accommodates thecable 122 at a cross-over position over aforefoot zone 125. The cable passes freely through channels located in thebody 131, channel guides 138, threadedtubes 134 and stopbumpers 136. A wearer adjusts the lock-outdevice 130 to assume a lock-out position by twisting thetwist tightening mechanism 132 to adjust the length “S” (seeFIG. 5B ) between thebody edge 133 and stopbumper edge 137. Theedge 137 of thestop bumper 136 contacts a surface of thecable guide members 128 and/or 129 to prevent the closure edges 114 and/or 116 from advancing towards each other while theboot 120 is being tightened or when the boot is in use during an athletic activity, for example. A user can turn thetwist tightening mechanism 132 to elongate or shorten the threadedtube 134 which increases or decreases the length “S” to vary the lock-out distances between the closure edges 114 and 116. Thus, if the wearer has a relatively wide forefoot, he would increase the length “S” by adjusting one or both of the threadedtubes 134 of the cable lock-outdevice 130 which is located in theforefoot zone 125 inFIG. 5A . In an implementation, the length “S” on one side of the cable lock-out device can be varied from about 0.5 to 1.5 inches. - It should be understood that the cable lock-out device could be used in other locations as well, such as in the upper cuff zone 123, where the
cable 122 crosses over the tongue. In addition, two or more cable lock-out devices could be used on a boot, and/or could be used in conjunction with other types of stop devices such as those described above. -
FIG. 5C is a cross-sectional view of the cable lock-outdevice 130 ofFIG. 5B . In this implementation, thebody 131 is made of molded plastic and includes channels to permit thecable 122 to freely move therethrough. The twist-tighteningmechanisms 132 include threadedsleeves 135 that can be twisted or turned by a wearer to either elongate or retract the threadedtubes 134 to vary the length “S” between thestop bumper edges 137 and thebody edge 133. Conventionally, the twist-tightening mechanisms are turned in a clockwise manner to extend the threaded tube, and turned in a counter-clockwise manner to retract the threaded tube. The wearer can therefore control the distance between the closure edges 114 and 116 of the boot by adjusting the twist-tighteningmechanisms 132. -
FIG. 5D illustrates an alternate implementation of a cable lock-outdevice 140. This implementation includes abody 141, fourtwist tightening mechanisms 142, four threadedtubes 144 and fourstop bumpers 146. Thecable 122 moves freely through the channels within the cable lock-outdevice 140. The lock-outdevice 140 provides a wearer with more adjustment options than the cable lock-outdevice 130 with respect to preventing the boot closure edges 114 and 116 in a zone or area from advancing towards each other. -
FIG. 6 illustrates yet another alternate embodiment of alace tension system 200 for asports boot 220. Thesport boot 220 includes an upperlateral flap 202 and a lowerlateral flap 204 on a side of the boot opposite an intermediatemedial flap 206 positioned over atongue 218. Atightening mechanism 224 is affixed to the upperlateral flap 202. Afirst cable 221 is operable to urgeedge 203 of theupper flap 202 towards theedge 205. Asecond cable 222 is operable to urgeedge 207 of the lower flap towards theedge 208. Thelace tension system 200 may also include embeddedcable guide numbers FIG. 6 , and includes cable-end tightening devices 230. -
FIG. 7A is an enlarged, perspective view of cable-end tightening device 230. The cable-end tightening device 230 includes a twist-tighteningmechanism 232, threadedmember 234 andend section 236. Theend section 236 includes anaperture 238 for accommodating a rivet, screw or other fastener to affix the cable-end tightening device 230 to the boot.FIG. 7B is an enlarged, top view of the cable-end device 230 ofFIG. 7A .FIG. 7C is an enlarged cross-sectional view of the cable-end tightener 230 ofFIGS. 7A and/or 7B. The threadedmember 234 is connected to an end ofcable teeth 233 of the twist-tighteningmechanism 232. Theend section 236 includes a free-spinningconnector portion 237. Thus, when in use, a wearer turns or twists themechanism 232 in a first direction to either pullcable 222 towards theend section 236 to tighten the cable system, or turns the mechanism in a second, opposite direction to extend the cable to loosen the cable system. Typically, themechanism 232 is turned in a clockwise manner to tighten the cable, and turned counter-clockwise to loosen the cable. In an implementation, the threadedmember 234 andteeth section 233 are about one-inch long to permit about one-inch of cable length adjustment. - Referring again to
FIG. 6 , thetightening mechanism 224 is configured to be used to separately tighten or loosen theupper flap 202 andlower flap 204 by reeling in or letting out thefirst cable 221 and/orsecond cable 222. Thus, thelace tension system 200 utilizes two separate cables to provide adjustment capability for two different zones. In addition,FIG. 6 showsprotective flaps 231 which can be used to cover the cable-end tightening mechanism 230. -
FIG. 8 illustrates yet another variation of alace tension system 300 for asports boot 320. The boot upper includes two opposed closure edges 314 and 316 that partially cover atongue 318. Thelacing system 300 includes acable 322,tightening mechanism 324, and cable guide members (not shown, but the cable guide members may be embedded within the boot upper and include channels to permit the cable to slide freely therethrough). Also included arefit adjustment elements 330 which can be positioned between opposing cable guide members. Thefit adjustment elements 330 do not require any tools in order to be adjusted, havetracks 334 shown affixed to thetongue 318, and operate to prevent the closure edges 314 and 316 from advancing toward each other. -
FIG. 9A is an enlarged top or front view of afit adjustment element 330 ofFIG. 8 . The fit adjustment element includes astop hook 332, atoothed track 334 and at least onefastener 336 to affix the track to thetongue 318. Thestop hook 332 can be adjusted along the length of thetrack 334 by a wearer as shown by arrow “B” so that it to engages theclosure edge 316 when in use. Arivet 336 or other fastener may function to limit the travel of thestop hook 332 so that it cannot be moved past the mid-line of the tongue, for example. -
FIG. 9B is a cross-sectional side view of afit adjustment element 330. As shown, thetoothed track 334 is attached to atongue 318 by arivet 336. In this implementation, thestop hook 332 include at least onetooth 333 on each of a pair offlexible arms 331 that can be positioned to engage with the teeth of thetoothed track 334. Thearms 331 of thestop hook 332 connect under thetoothed track 334 to create a pivot mechanism. A user presses downward on therear handle portion 335 to cause a pivoting action that disengages theteeth 333 from thetoothed track 334 and lifts thestop hook 332 to reposition it by sliding the stop hook along thetoothed track 334. Once a desired position is reached the user presses the stop hook towards the toothed track so that theteeth 333 will engage therewith. When thestop hook 332 is engaged, it prevents theclosure edge 316 from moving toward the opposite closure edge 314 (seeFIG. 8 ). As the wearer reels in thecable 322 to tighten the boot about the foot, the closure edges contact the stop hooks 332 which then securely engage with the toothed track. - Referring again to
FIG. 8 , two pairs offit adjustment elements 330 are shown, one to regulate the fit about anupper cuff area 340 and another to regulate the fit about aforefoot area 350. But one skilled in the art would recognize that other configurations, which may utilize more or less adjustment fit elements, could be used to provide fit adjustment options for a wearer. -
FIG. 10 is another embodiment of alace tension system 400 for asports boot 420. Theboot 420 includes two opposed closure edges 414 and 416 that cover the edges of atongue 418. The lacing system includescables tightening mechanism 424 and cable guide members (not shown, but the cable guide member may be embedded within the boot upper and include channels to permit the cable to slide freely therethrough). Also included are cablelength adjustment devices 430 that are affixed to thetongue 418 by known methods, such as by stitching or by adhesive means. Theadjustment devices 430 include a plurality ofend stations 432 that are configured to mate with anend cap 423 of thecables FIG. 10A is an enlarged drawing illustrating acable 421 having anend cap 423. In the implementation ofFIG. 10 , thetightening mechanism 424 is operable to tighten or loosen thefirst cable 421 and thesecond cable 422. Thefirst cable 421 operates to adjust the fit of alower portion 440, and thecable 421 is routed straight downward through thetongue 418 so that flexing of the ankle of a wearer during use does not affect the fit of the lower boot. Thesecond cable 422 is operable to adjust the fit of an upper portion of 450 of the boot. Thiscable 422 follows a serpentine path as shown byarrows 422 a and terminates at anend station 432 adjacent thetightening mechanism 424. A wearer utilizes theend station 432 of theadjustment device 430 to adjust the length of one or bothcables -
FIG. 11 shows an alternative embodiment of a cablelength adjustment device 530. The adjustment device includes oneend station 532 for accommodating an end cap 423 (seeFIG. 10A ) of acable 422, and aserpentine path 534 for use in adjusting the cable length. As shown, only a portion of theserpentine path 534 has been used inFIG. 11 . Thus, the length of the cable can be varied depending on whether some, none or all of the serpentine path is used. The cablelength adjustment device 530 may be made of molded plastic, rubber or a durable composite material, and may be stitched or otherwise attached to the tongue or other portion of an article of footwear. - It should be noted that the lace tension systems shown in
FIGS. 6 and 10 utilize two separate cables to separately adjust two zones on an article of footwear, whereas the systems ofFIGS. 1, 4 and 8 may utilize one continuous cable but are operable for adjustment of multiple zones. One of skill in the art would recognize that other configurations are possible that could use one, two or more cables for adjustment of one or more zones. - The tightening mechanism in the implementations shown in the figures generally includes a circular housing and a circular knob rotatably mounted thereon. The knob may be rotated in a clockwise manner to wind the ends of the lace into the housing onto a spool or spools to thereby tension the lace and to reduce the slack in the lacing system. The tightening mechanism may include an internal gearing mechanism that allows a wearer to manually turn the knob to retract the lace. The internal mechanism may also be configured to permit incremental winding to retain predetermined amounts of lace as the knob is turned, and may include a ratchet mechanism or other arrangement to resist unwinding of the spool. The knob may be turned manually by a wearer, or a small motor may be included to provide turning power. In order to loosen the laces, a release lever may be provided to disengage the spool from the internal gearing mechanism to unravel the lace so that the closure edges can be separated and the wearer can remove her foot from the boot.
- The footwear lacing systems described herein advantageously allow users to adjust the boot closure edge to closure edge distance of one or more zones to obtain a customized fit. The low friction cable along with the low friction cable guides and/or cross guide members allow for easy sliding of the cable within the guides. Use of low friction materials on the surface of the tongue also facilitates movement of the closure edges as the cable is tightened.
- Although particular implementations have been described, it should be understood that one of skill in the art could make many changes or modifications that would fall within the scope of the invention. For example, the various type of stop devices, cable guide members, cross guide members, cable lock-out devices, cable-end tightening devices and other described devices could be used with one another in various combinations, and could be used with one or more cables to provide a lace tension system.
