Patent Application
20170065027
The present invention relates to footwear, and more particularly, to lacing systems for use with footwear to secure the same to a wearer's foot.
There is a variety of footwear used for different purposes. Some footwear includes unique lacing systems that provide certain aesthetics and/or functional attributes. One type of footwear lacing system features a lace that wraps from the front of the footwear, travels around a heel of the footwear, and extends again toward the front of the footwear. This conventional lace, however, is inserted between the upper and the lining of the footwear. Much of the lace is itself concealed within and hidden by an outer layer of the upper. Generally, the concealed lace extends below the surface of material designed to form an ankle collar around an ankle opening of the shoe.
While the above conventional lacing system can satisfactorily ensure that the associated footwear remains on the foot of a user, it presents some issues. Specifically, because the lace extends below the upper, and partially through an ankle collar interior, as it wraps around the rear of the heel, it is very difficult to replace that lace or customize that lace. For example, special tools must be used to pry and/or pull the lace under the upper material to an accessible position and/or to otherwise remove the lace. This can cause frustration to anyone desiring to replace a broken lace and/or customize their footwear with a different aesthetic lace.
Accordingly, their remains room for improvement in connection with functional lacing systems for footwear.
An article of footwear is provided including a 360° lacing system configured to secure the footwear to a wearer's foot. The lacing system includes an elongated lace that extends rearward adjacent an ankle collar, around a heel of the footwear, and forward again. The lacing system includes one or more fairleads that project outwardly from the ankle collar. The fairleads define fairlead holes through which the lace extends and is guided around the ankle collar. The lace is slidable relative to the holes, and thus the fairleads, and can be removed from and replaced relative to the fairleads with minimal effort. This provides a user with a functional 360° lacing system having a lace that can be easily removed and/or replaced.
In one embodiment, the footwear includes an upper having an ankle collar and a tongue cooperatively surrounding an ankle of a wearer when the footwear is worn by the wearer. The ankle collar includes an ankle collar rear portion extending around a heel of the wearer when the footwear is worn by a wearer.
In another embodiment, the upper includes at least one fairlead extending outwardly from the ankle collar. The fairlead can include a first base that engages the ankle collar, a body and an optional post. The body can extend outwardly from the base and can define a lace hole. The optional post can extend inwardly through at least a portion of the ankle collar to secure the fairlead to the ankle collar.
In still another embodiment, the at least one fairlead can be located closer to the ankle collar rear portion than the tongue. Where multiple fairleads are included on the ankle collar, some of them, however, may be located closer to the tongue than the ankle collar rear portion.
In yet another embodiment, the upper includes an elongated lace including first and second ends. The elongated lace extends from near the tongue, rearward adjacent the ankle collar. The lace extends through a first fairlead lace hole, and around the heel of the wearer. The lace extends through a second fairlead lace hole back toward the tongue. Optionally, the elongated lace encircles the ankle of the wearer 360°, with the first and second ends joinable at a knot to secure the footwear to the wearer's foot.
In even another embodiment, the elongated lace remains exterior to the ankle collar as the elongated lace extends adjacent the ankle collar.
In a further embodiment, the upper defines a side eyelet, and at least one lace eyelet forward of the side eyelet. The elongated lace extends from a forward fairlead, through the side eyelet, and into an interior of the upper. The lace extends to the lace eyelet in the interior, then out through the lace eyelet to an exterior of the upper. The lace can be laced and crisscrossed over the tongue and tied to secure the footwear. Upon tightening the lace, it snugs around the ankle of the wearer as well to enhance securement to the foot.
In still a further embodiment, a method is provided. The method includes providing footwear with an upper having an ankle collar extending around an ankle opening of the footwear, the ankle collar having attached thereto multiple fairleads defining lace holes; stringing an elongated lace from a first location adjacent the tongue, through a fairlead first lace hole, around the heel of the wearer, through a fairlead second lace hole, back toward a second location adjacent the tongue on an opposite side of the upper; and joining first and second ends of the elongated lace at a knot over the tongue to secure the footwear on the wearer's foot. Optionally, the elongated lace remains entirely exterior to the ankle collar, and the elongated lace encircles the ankle of the wearer 360°. Further optionally, no tools are required to string the elongated lace around the ankle collar and through the fairleads, as this task can be performed manually.
The footwear and related method of the current embodiments provide a simple and functional 360° lacing system. Where the elongated lace is slidably and removably disposed in the fairleads, that lace can easily be replaced when worn, or customized with different textured and/or colored laces depending on the user's preference. Thus, the replacement and servicing of the functional lace in the current footwear is greatly facilitated and simplified.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.
Before the embodiments of the invention are explained in detail, it is to be understood that the invention is not limited to the details of operation or to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention may be implemented in various other embodiments and of being practiced or being carried out in alternative ways not expressly disclosed herein.

An article of footwear in accordance with a current embodiment is shown in
Although the current embodiments are illustrated in the context of a casual shoe, they may be incorporated into any type or style of footwear, including working boots, safety shoes, performance shoes, hiking shoes, trail shoes and boots, hiking boots, all-terrain shoes, barefoot running shoes, athletic shoes, running shoes, sneakers, conventional tennis shoes, walking shoes, multisport footwear, dress shoes or any other type of footwear or footwear components. It also should be noted that directional terms, such as “vertical,” “horizontal,” “top,” “bottom,” “upper,” “lower,” “inner,” “inwardly,” “outer” and “outwardly,” are used to assist in describing the invention based on the orientation of the embodiments shown in the illustrations. Further, the terms “medial,” “lateral” and “longitudinal” are used in the manner commonly used in connection with footwear. For example, when used in referring to a side of the shoe, the term “medial” refers to the inward side (that is, the side facing the other shoe) and “lateral” refers to the outward side. When used in referring to a direction, the term “longitudinal direction” refers to a direction generally extending along the length of the shoe between toe and heel, and the term “lateral direction” refers to a direction generally extending across the width of the shoe between the medial and lateral sides of the shoe. The use of directional terms should not be interpreted to limit the invention to any specific orientation.
Further, as used herein, the term “arch region” (or arch or midfoot) refers generally to the portion of the footwear or sole assembly corresponding to the arch or midfoot of the wearer's foot; the term “forefoot region” (or forefoot) refers generally to the portion of the footwear forward of the arch region corresponding to the forefoot (for example, including the ball and the toes) of a wearer's foot; and the term “heel region” (or heel) refers generally to that portion of the footwear rearward of the arch region corresponding to the heel of the wearer's foot. The forefoot 17, arch or midfoot 18, and heel 19 regions are generally identified in
The upper 20 optionally is of a Strobel construction in which the foot-receiving upper interior 21 is closed on its bottom or lowermost portion by a Strobel board, an insole board, sock or liner 22 or other similar component. Although not shown, the footwear 10 can include a footbed and/or other upper components with the footbed fitted into the upper 10.
For purposes of disclosure, the embodiments herein are described in connection with footwear in the form of a casual shoe 10 having an upper 20, which as mentioned above, optionally can include a Strobel construction. The upper 20 is joined with the outsole 30. The joining of the outsole 30 and the upper 20 can be accomplished using adhesives, cement, injection molding, pour molding or any other technique used to join an upper and outsole. As illustrated, the insole board or liner 22 can rest or be placed immediately adjacent the outsole 30.
The outsole 30 can be disposed below the upper 20 and any optional midsole included in the construction. The outsole 30 can be constructed from one or more materials. The current embodiment can be constructed from rubber and can include lugs, tread, or other gripping elements. Alternatively, it can be constructed from a thermoplastic polyurethane elastomer (TPU), nylon or other polymer blend that includes nylon and/or TPU. Of course, the outsole can be constructed from any relatively wear resistant polymer, elastomer and/or natural or synthetic rubber or other materials capable of providing the desired functional characteristics. Other materials such as fiber-reinforced polymers can be used. These can include epoxy, polyethylene, polyester, thermosetting plastic reinforced with carbon, glass and/or aramid fibers.
As illustrated in
The vamp 13 also can include lateral and medial wings 13L and 13M which extend upwardly over the instep region, optionally extending from the side quarters 15, 16 and/or a forward portion of the ankle collar 70. These wings can include opposing edges 13M1 and 13L1 that generally face toward one another and extend above the tongue 15A. The opposing edges can each define respective lace eyelets 22M and 22L, respectively. These lace eyelets can be in the form of a metal, composite and/or plastic collar that provides a bounded hole through the vamp in that region. Alternatively, the lace eyelets can be simple holes defined through the respective component of the upper through which a lace extends. As illustrated in
As shown in
Generally, the side quarters can extend rearward from the vamp 13 toward a heel portion 12 of the upper 20. The heel portion can be formed so that the side quarters and heel portion are integrally formed with one another. In one embodiment, all of these components can be constructed from a single sheet or piece of leather, canvas, fabric or other material. Generally, the heel portion 12 wraps around the heel of the wearer when the wearer's foot is located in the footwear 10. Thus, the heel portion 12 naturally transitions from the medial first side quarter 15 to the lateral second side quarter 16 around the heel of the wearer. Although illustrated as extending from the ankle collar 70 all the way to the outsole 30, in some cases the heel portion 12 can be truncated so that there is an opening adjacent the heel. In addition, certain portions of the side quarters 15, 16 can be deleted or removed so that there are open holes or apertures (not shown) in these components Likewise the vamp can define one or more holes or apertures (not shown). Generally, these optional holes or apertures can facilitate airflow and/or water expulsion relative to the interior of the footwear.
As illustrated in
The upper 20 can include an ankle collar 70 as described above and shown in
The ankle collar 70 can include an ankle collar first side 71 that extends away from the vamp, generally above the first side quarter 15 on the medial side M of the longitudinal axis LA. The ankle collar can transition rearward to an ankle collar rear portion 72 that is disposed generally above the heel portion 12 of the upper. Here, the ankle collar rear portion 72 can also traverse the longitudinal axis LA rearward of the heel of the wearer. The ankle collar rear portion as illustrated can be of an arcuate and/or parabolic shape to comfortably engage the rear of a wearer's heel, adjacent an Achilles tendon of the wearer. Although not shown, additional padding can be disposed in this region to provide cushion.
The ankle collar rear portion 72 can transition to the ankle collar second side 73. This ankle collar second side 73 can extend toward and away from the vamp, generally connecting the ankle collar rear portion with the vamp. The ankle collar second side 73 also can extend above the second side quarter 16 on the lateral side L the longitudinal axis LA. Cooperatively, the ankle collar second side 73, ankle collar heel rear portion 72 and ankle collar first side can be joined with one another to form the ankle collar 70. This ankle collar 70 and the tongue 15A can cooperatively surround an ankle of the wearer when the footwear is worn by the wearer.
As shown in Fig, 6, the ankle collar 70 optionally can be constructed from one or more sheets of material. In particular, the ankle collar can include an exterior or first portion 74 of a sheet of material that extends upward toward an uppermost part of the ankle color. The first portion 74 can be optionally folded over upon itself at a fold 75. The fold optionally can transition to a second portion 76 of a sheet of material, which can extend back downward from the fold line 75. Of course, the fold 75 can be deleted from the construction, with the first portion 74 simply stitched, adhered or otherwise secured to the second portion 76, and with both portions being separate independent sheets or pieces of material.
Generally, the second portion of the sheet faces the interior of the ankle collar opening 11. The first portion 74 faces exteriorly or outward, away from the ankle collar opening 11. The second portion 76 extends to an end 76E. This end can be stitched directly to the first portion 74 with stitching 76S. In other cases, this end 76E can be glued, fastened, riveted or otherwise connected to the first portion 74. In yet other constructions, the end 76E may be constructed to join with an intermediate component, such as another layer or sheet disposed adjacent the exterior portion, the side quarter, or other component of the footwear.
Optionally, as shown in
The footwear 10, and in particular its lacing system, includes one or more fairleads 60 that are disposed adjacent the ankle collar opening 11, and optionally join directly with an exterior facing surface 78 of the ankle collar 70. With reference to
Generally, the first 61 and second 62 fairleads can be located the same distance rearward from the rear edge 15R of the tongue, and the same distance forward from the ankle collar rear portion 72. Of course, in certain applications the distances of each of the fairleads can be varied and/or staggered or offset relative to one another. Optionally, the first and second fairleads 61, 62 can be located closer to the ankle collar rear portion 72 and/or the heel portion 12 of the upper 20 than to the rear edge 15R or the tongue 15A.
The number of fairleads can vary depending on the particular application and desired aesthetic of the footwear. Optionally, as shown in
When multiple fairleads are utilized on a same side of the longitudinal axis LA, they can be aligned along a common fairlead axis FA. As shown in
The fairleads themselves can define fairlead lace holes 64. The fairlead lace holes of fairleads disposed on the same lateral or medial side of the longitudinal axis can themselves include fairlead lace hole axes that are substantially aligned with one another along the common fairlead axis FA. Of course, with some footwear, those fairlead lace hole axes might be slightly offset relative to one another and/or the common fairlead axis by optionally 1° to 10°, further optionally 2° to 5°, depending on the curvature of the ankle collar from one fairlead to the next or other features of the footwear.
Optionally, the fairlead lace hole axes can be aligned so that they are approximately parallel to the longitudinal axis LA of the footwear. By approximately parallel, it is meant that the fairlead hole axes align so that they are optionally parallel to the longitudinal axis, and/or further optionally offset relative to the longitudinal axis LA at an angle a which can be 1° to 25°, and/or 1° to 10°. This can contrast the eyelet axes EA shown in
The fairleads can be specifically configured to slidably restrain the lace 50 around the ankle collar and the ankle opening in general, without the lace extending into an interior portion 21 of the upper and adjacent or around the ankle collar 70. The lace 50 is retained and held in place entirely exterior to the ankle collar 70 and its respective ankle collar portions, for example the ankle collar first side, the ankle collar rear portion in the ankle collar second side, as well as outside the ankle collar cavity.
The lace 50, however, can optionally extend into an interior 21 of the upper 20 somewhat forward of the ankle opening or generally forward of a rear edge 15R of the tongue 15A. As an example, the lace 50 can extend through one or more side eyelets 23M, 23L and into the interior 21 of the upper 20, forward of the ankle collar 70.
Returning to the construction of the fairleads 60, they may take on a variety of forms. As illustrated in
The fairlead 61 can include a fairlead body 62 that extends outward from a base 63. The body 62 of the fairlead 61 can include an exterior surface 62E that faces outward, away from the ankle collar opening in the ankle collar in general. This exterior surface of the fairlead, as well as the body, can transition to the base 63. The fairlead body 62 can define a fairlead lace hole 64, which optionally can be completely circumferentiated aided by the base and/or body. In such a construction, the lace hole, and thus the body and/or base can completely circumferentiate the lace through the lace hole. Of course, in some cases, only partial circumferentiation is desired. This fairlead lace hole 64 extends completely through the fairlead, generally from the fairlead rearward surface 61F to the fairlead rear surface 61R.
As illustrated in
As shown in
As shown in
As shown in
Alternatively, the fairlead, its post and/or fastener can be adhered, hot welded, stitched, or otherwise joined with the first portion or ankle collar in general. In other constructions, the base 63 can be adhered, hot welded, stitched (in which case, there can be stitch holes in the base), or otherwise joined, along its interior 631 to the exterior 78 the ankle collar 70.
An alternative construction of the fairlead is illustrated in
As explained above, the footwear in particular the lacing system includes an elongated lace 50. The elongated lace 50 can be in the form of a cord, a rope, a wire, a strand, a filament, a yarn, an elongated continuous piece of rawhide or leather, or some other elongated member of a sufficient length to wrap rearwardly around at least a portion of the ankle opening 11. The lace also can be sized to have a diameter that fits through the respective fairlead lace holes. Optionally, the diameter can be selected so that the lace is physically smaller than the interior diameter or dimension of the lace hole, thereby allowing the lace to slide relative to the fairlead more easily. Of course even where the diameter is the same size or slightly larger than the interior diameter or dimension of the lace hole, the lace still can slide relative to the hole and fairlead in general.
The lace as illustrated in
The elongated lace extends generally from a location adjacent the tongue 15A, rearward adjacent, but entirely exterior to the ankle collar 70. The lace extends through the fairlead lace holes on the medial side M, depending on the number of fairleads, and around the heel of the wearer. From there forward, the lace extends through the fairlead lace holes on the lateral side L, depending on the number of fairleads. Optionally, the lace extends through the first fairlead 61 on the medial side and the second fairlead 62 on the lateral side of the longitudinal axis LA. The lace extends back toward a location adjacent the tongue 15A.
In addition to extending through the respective fairleads, the lace can extend exterior to the ankle collar, generally around at least a portion of the ankle collar opening 11. The lace also can extend through the respective side eyelets 23M and 23L. Where it does so, the lace can extend from an exterior of the footwear adjacent the vamp and/or tongue and into an interior 21 of the upper 10. The lace 50 can then traverse toward the lace eyelets 23M and 23L further extending through those elements. In doing so, the lace transitions from the interior of the upper, back to an exterior of the upper and into the environment.
The ends 51 and 52 of the lace can be crisscrossed and extend again through respective, additional lace eyelets 23M and 23L, transitioning back more close to the rear edge 15R of the tongue 15A. As mentioned above, the ends can be tied with one another to secure the lace to the footwear and over the instep of the wearer.
In the footwear of the current embodiments, the elongated lace can encircle the ankle the wearer 360°. The first second ends of the lace can be joinable in a knot so as to ensure the footwear is securely joined with the wearer's foot. The lace also can be slidable or movable relative to the fairleads. With the fairlead construction, the lace also can be replaceable and/or removal relative to those structures to facilitate replacement of a worn lace or customization with a special aesthetic lace.
The current embodiments also provide a method of replacing a lace in a lacing system of footwear as shown in
A user can manually, without the use of tools, string an elongated lace through the respective eyelets and fairleads. For example, the user can string the elongated lace from a first location adjacent the tongue and/or vamp, through a first fairlead lace hole, around a heel of the footwear, through a second fairlead lace hole, and back toward another location adjacent the tongue and/or vamp on the opposite side of longitudinal axis of the upper. The user can then lace the ends of the lace through the respective side eyelets and lace eyelets, and tie a knot to secure those ends. After the user is done, the ends are joined at the knot generally over the tongue and/or vamp to ensure the footwear is securely joined to the wearer's foot. This lacing system provides 360° securement of the lace about the ankle and/or foot of the wearer.
