Aspects of the present invention relate generally to systems and methods for securing a foot in a foot-receiving device, such as an article of footwear. In at least some examples, at least a portion of the closure systems according to the invention may wrap around the foot-receiving chamber of the foot-receiving device. Such systems and methods, in at least some examples, advantageously may be used in footwear or other foot-receiving devices for children.
Conventional footwear typically attaches to a wearer's foot via shoelaces. While effective, shoelaces can be difficult for some to use. For example, some people can have difficulty tying shoelaces, e.g., because of a lack of finger dexterity, arthritis, or other conditions, or the like. Children can have particular difficulty in securely tying shoelaces.
Other problems can exist with the use of conventional shoelaces. For example, the laces can inadvertently loosen in use, resulting in safety hazards for wearers, e.g., from tripping, unexpected shoe loss, etc. This is a particular hazard for athletic footwear used in competition, practice, and the like; in children's footwear; etc. Additionally, shoelaces can form tight knots if not properly loosened, making it difficult to untie the laces and remove the shoe. The presence of knots can be particularly frustrating for children and others who have difficulty manipulating laces.
Accordingly, it would be advantageous to provide an alternative closure or securing system for footwear or other foot-receiving device products that is easy and quick to use, even for children, and that can securely and comfortably hold a foot in the foot-receiving device.
Aspects of the present invention relate to foot-receiving devices and systems and methods for securing a wearer's feet in such devices. Foot-receiving devices (including articles of footwear) in accordance with example aspects of this invention may include: (a) a foot-covering member (e.g., an upper member); (b) a foot-supporting member (e.g., a sole member) engaged (directly or indirectly) with the foot-covering member, wherein the foot-covering member and the foot-supporting member, at least in part, define a foot-receiving chamber; and (c) a securing system for at least partially securing the foot-receiving device to a user's foot. The securing system may include: (i) a strap member having a first portion fixedly engaged with the foot-covering member and/or the foot-supporting member at a toe or mid-foot area thereof, and (ii) a securing element for holding the strap member. The strap member may be located so as to extend at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber.
Additional examples of foot-receiving devices in accordance with this invention may include: (a) a foot-covering member (such as an upper member); (b) a foot-supporting member (such as a sole member), wherein the foot-covering member and the foot-supporting member, at least in part, define a foot-receiving chamber; (c) a first strap member having a first portion engaged with the foot-covering member and/or the foot-supporting member, wherein the first strap member extends along a first portion of the foot-covering member; and (d) a second strap member having a first portion engaged with the foot-covering member and/or the foot-supporting member, wherein the second strap member extends at least one time along a second portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a first portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber. Optionally, if desired, a third strap member having a first portion engaged with the foot-covering member and/or the foot-supporting member may be included. At least some of the strap members may be used secure the foot-receiving device to a user's foot.
Additional aspects of this invention relate to methods for producing foot-receiving devices, such as articles of footwear, of the type described above. Such methods may include, for example: (a) providing a foot-receiving device including a foot-covering member and a foot-supporting member that define a foot-receiving chamber; (b) engaging a first portion of a strap member with the foot-covering member and/or the foot-supporting member at a toe or mid-foot area thereof; (c) wrapping the strap member around the foot-receiving device such that the strap member extends at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber; and (d) providing a securing system for holding a foot in the foot-receiving chamber, wherein the securing system utilizes the strap member.
Other method aspects in accordance with examples of this invention may include, for example: (a) providing a foot-receiving device including a foot-covering member and a foot-supporting member that define a foot-receiving chamber; (b) engaging a first portion of a first strap member with the foot-covering member and/or the foot-supporting member; (c) engaging a first portion of a second strap member with the foot-covering member and/or the foot-supporting member; (d) extending the second strap member around the foot-receiving device such that the second strap member extends at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber; and (e) engaging the first strap member with the second strap member. Optionally, if desired, a third strap member may be engaged with the foot-covering member and/or the foot-supporting member, wherein the third strap member extends along a third portion of the foot-covering member.

In the following description of various examples of the invention, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures, systems, and environments in which the invention may be practiced. It is to be understood that other specific arrangements of parts, example structures, systems, and environments may be utilized, and that structural and functional modifications may be made without departing from the scope of the present invention. Also, while the terms “top,” “bottom,” “side,” “front,” “rear,” “above,” “below,” “under,” “over,” and the like may be used in this specification to describe various example features and elements of the invention, these terms are used herein as a matter of convenience, e.g., based on the example orientations shown in the figures and/or a typical orientation of a product in use. Nothing in this specification should be construed as requiring a specific three dimensional or relative orientation of structures in order to fall within the scope of this invention.
Various specific examples of the invention are described in detail below in conjunction with the attached drawings. To assist the reader, this specification is broken into various subsections, as follows: Terms; General Description of Articles of Footwear and Other Foot-Receiving Devices in Accordance with Examples of this Invention; Specific Examples of the Invention; and Conclusion.
The following terms are used in this specification, and unless otherwise noted or clear from the context, these terms have the meanings provided below.
“Foot-receiving device” means any device or product into which a wearer places at least some portion of his or her foot. In addition to all types of footwear (described below), “foot-receiving devices” include, but are not limited to: bindings and other devices for securing feet in snow skis, cross country skis, water skis, snowboards, and the like; bindings, clips, or other devices for securing feet in pedals for use with bicycles, exercise bikes, games, and the like; bindings, clips, or other devices for receiving feet during play of video games; and the like.
“Footwear” means any type of product worn on the feet, and this term includes, but is not limited to: all types of shoes, boots, sneakers, sandals, thongs, flip-flops, mules, scuffs, slippers, sport-specific shoes (such as golf shoes, ski boots, etc.), and the like. “Footwear” may protect the feet from the environment and/or enhance a wearer's performance (e.g., physically, physiologically, medically, etc.). As used herein, the longitudinal direction of an article of footwear may be considered as generally being comprised of three sections, namely a forefoot or toe area in the foremost third of the shoe, a midfoot or arch area in the middle third, and a rearfoot or heel area in the rearmost third.
“Foot-covering members” include one or more portions of a foot-receiving device that extend at least partially over and/or at least partially cover at least some portion of the wearer's foot, e.g., so as to assist in holding the foot-receiving device in place with respect to the wearer's foot. “Foot-covering members” include, but are not limited to, upper members of the type provided in some conventional footwear products.
“Foot-supporting members” include one or more portions of a foot-receiving device that extend at least partially beneath at least some portion of the wearer's foot, e.g., so as to assist in supporting the foot and/or attenuating the reaction forces to which the wearer's foot would be exposed, for example, when stepping down in the foot-receiving device. “Foot-supporting members” include, but are not limited to, sole members of the type provided in some conventional footwear products. Such sole members may include conventional outsole, midsole, and/or insole members.
“Ground-contacting elements” or “members” include at least some portions of a foot-receiving device structure that contact the ground in use, and/or at least some portions of a foot-receiving device structure that engage another element or structure in use. The term “ground,” as used herein, means any surface that a foot or an article of footwear contacts in use, including but not limited to: grass, dirt, sand, snow, ice, tile, flooring, carpeting, and the like. Such “ground-contacting elements” may include, for example, but are not limited to, outsole elements provided in some conventional footwear products. “Ground-contacting elements” in at least some example structures may be made of suitable and conventional materials to provide long wear and protect the foot and/or to prevent the remainder of the foot-receiving device structure from wear effects, e.g., when contacting the ground or other surface in use.
In general, aspects of this invention relate to systems for securing feet in foot-receiving devices (e.g., closure systems for footwear and other foot-receiving devices). Foot-receiving devices according to at least some examples of this invention may include: (a) a foot-covering member; (b) a foot-supporting member engaged (directly or indirectly) with the foot-covering member, wherein the foot-covering member and the foot-supporting member, at least in part, define a foot-receiving chamber; and (c) a securing system for at least partially securing the foot-receiving device to a user's foot. The securing system may take on various forms in examples of this invention. For example, the securing system may include: (i) a strap member having a first portion fixedly engaged with at least one of the foot-covering member or the foot-supporting member in a toe or mid-foot portion thereof, and (ii) a securing element for holding the strap member in place with respect to at least one of the foot-covering member or the foot-supporting member (the securing element may be located and/or engaged with the foot-covering member or the foot-supporting member at the mid-foot and/or heel area of the foot-receiving device structure). The strap member may be located so as to extend at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber. If desired, the strap member may be fixedly engaged with the foot-covering member and/or the foot-supporting member through a selectively releasable connection, e.g., to enable replacement of the strap, if necessary or desired.
The securing element for holding or otherwise engaging the strap member may take on various forms or constructions without departing from the invention. For example, the securing element may include: a hook-and-loop fastener arrangement, a buckle arrangement, a clasp arrangement, a magnetic fastener arrangement, and/or any other suitable or desired mechanical connector or fastener arrangement, including conventional connector or fastener arrangements that are known and used in the art. If desired, at least some portion of the securing element may include a mechanical member that engages the strap member (such as a buckle, a portion of a hook-and-loop fastener arrangement, a clasp, a direction change element, or the like), wherein the mechanical member is fixedly connected to at least one of the foot-covering member or the foot-supporting member (e.g., at the heel or mid-foot portion of the foot-receiving device, optionally via a strap member connected to the foot-covering member or the foot-supporting member).
If desired, in at least some example foot-receiving device structures in accordance with this invention, at least some portions of the foot-covering member may include one or more “track elements” extending along its surface (e.g., its exterior surface), wherein at least some portions of the strap member lie on and/or extend along the track element(s). The “track elements” may be made from a material having a low coefficient of friction to movement (e.g., sliding) with respect to the strap member, to enable easy tightening and loosening of the strap member (e.g., during foot insertion and removal activities) while also reducing or preventing damage or wear to the strap member and/or the foot-covering member. If desired, the track element(s) may be covered or partially covered (e.g., by a material panel, by passing through a passageway defined in the foot-covering member, or the like), and the strap member may pass between the track element and the material panel and/or through the passageway.
As described above, the strap member also may extend around the bottom portion of the foot-receiving chamber. In at least some example structures, a groove may be defined in the foot-supporting member and/or the foot-covering member, wherein the strap member extends through the groove. The interior of the groove may be lined with a material (such as a rigid thermoplastic material, e.g., made by injection or compression molding) that may help maintain a stable groove or tunnel structure, help prevent wear of the midsole material, help prevent wear of the strap, and/or help maintain a low coefficient of friction between the strap and other elements of the foot-receiving device structure. This groove lining material, in at least some examples, may extend around the side edges of the foot-supporting member toward the foot-covering member. In additional example structures, a cover element may be provided (e.g., engaged with at least one of the foot-covering member or the foot-supporting member) for covering the groove, e.g., to allow user access to the groove for changing strap members, if necessary or desired, etc.
Some example structures and devices in accordance with this invention relate to articles of footwear, such as athletic footwear, that include closure systems and/or securing systems like those described above. Such pieces of footwear may include: (a) an upper member; (b) a sole member engaged (directly or indirectly) with the upper member, wherein the upper member and the sole member, at least in part, define a foot-receiving chamber; and (c) a securing system for securing the article of footwear to a wearer's foot. Such securing systems may include, for example: (i) a strap member having a first portion fixedly engaged with at least one of the upper member or the sole member at a toe or mid-foot portion thereof, and (ii) a securing element for holding the strap member (in some examples, the securing element may be located and/or engaged with the upper member or the sole member at the mid-foot and/or heel area of the structure). This strap member may extend at least one time along a portion of the upper member and around a top portion of the foot-receiving chamber and at least one time along a portion of the sole member and around a bottom portion of the foot-receiving chamber. Footwear articles of this type further may include additional strap members, securing elements, grooves, track elements, material panels, passageways, cover members, and/or the like, e.g., like those described above.
Additional example aspects of this invention may include foot-receiving devices (such as articles of footwear) that include: (a) a foot-covering member (such as an upper member); (b) a foot-supporting member (such as a sole member) engaged (directly or indirectly) with the foot-covering member, wherein the foot-covering member and the foot-supporting member, at least in part, define a foot-receiving chamber; (c) a first strap member having a first portion engaged with at least one of the foot-covering member or the foot-supporting member, wherein the first strap member extends along a first portion of the foot-covering member; and (d) a second strap member having a first portion engaged with at least one of the foot-covering member or the foot-supporting member, wherein the second strap member extends at least one time along a second portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a first portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber. The first strap member and the second strap member, at least in part, are engaged to secure the foot-receiving device (e.g., an article of footwear) to a wearer's foot. Of course, articles of footwear or other foot-receiving devices of this type also may include additional strap members, securing elements, grooves, track elements, material panels, passageways, cover members, and/or the like, e.g., like those described above.
In at least some example structures according to the invention, foot-receiving devices of the type described above may include a third strap member having a first portion engaged with at least one of the foot-covering member or the foot-supporting member, wherein the first strap member extends along a third portion of the foot-covering member (the third strap member may be located and/or engaged, in at least some examples, at the mid-foot or heel area of the foot-receiving device). As examples, this third strap member may include a mechanical clasp or clamp element or other connector element that engages the second strap member. Optionally, the first strap member may include a direction change member, and the second strap member may engage this direction change member, change direction, and then extend to engage the mechanical clasp or clamp element or other connector element of the third strap member. If desired, in at least some examples of this invention, the first strap member and the third strap member may constitute opposite ends of a single strap member, e.g., a strap member that extends along the foot-supporting member and/or beneath the bottom portion of the foot-receiving chamber (optionally through a groove provided in the foot-covering member and/or the foot-supporting member) so that the free ends of the strap member are loose and available on opposite sides of the foot-covering member. Any or all of the first, second, or third strap elements may extend through passageways, beneath material flaps, along track elements, through grooves, or the like without departing from the invention.
Additional aspects of this invention relate to methods for using foot-receiving devices, such as articles of footwear, of the types described above. Such methods may include, for example: (a) providing a foot-receiving device including a foot-covering member and a foot-supporting member engaged (directly or indirectly) with the foot-covering member so as to, at least in part, define a foot-receiving chamber; (b) engaging a first portion of a strap member with at least one of the foot-covering member or the foot-supporting member; (c) wrapping the strap member around the foot-receiving device such that the strap member extends at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber; and (d) providing a securing system for at least partially holding a foot in the foot-receiving chamber, wherein the securing system utilizes the strap member.
Other method aspects in accordance with some examples of this invention may include: (a) providing a foot-receiving device including a foot-covering member and a foot-supporting member engaged (directly or indirectly) with the foot-covering member so as to, at least in part, define a foot-receiving chamber; (b) engaging a first portion of a first strap member with at least one of the foot-covering member or the foot-supporting member; (c) engaging a first portion of a second strap member with at least one of the foot-covering member or the foot-supporting member; (d) extending the second strap member around the foot-receiving device such that the second strap member extends at least one time along a portion of the foot-covering member and around a top portion of the foot-receiving chamber and at least one time along a portion of the foot-supporting member and around a bottom portion of the foot-receiving chamber; and (e) engaging the first strap member with the second strap member. Optionally, if desired, a first portion of a third strap member may be engaged with at least one of the foot-covering member or the foot-supporting member, wherein the third strap member extends along a third portion of the foot-covering member. This third strap member, along with the various other strap members, may be used, at least in part, to secure a wearer's foot in the foot-receiving chamber.
Method aspects in accordance with examples of this invention further may include one or more of the following steps: (a) placing a foot in the foot-receiving chamber; (b) securing the foot in the foot-receiving chamber using the securing system and/or strap arrangements; (c) disengaging one or more of the strap members from the foot-covering member and/or the foot-supporting member; and/or (d) engaging a new strap member with at least one of the foot-covering member or the foot-supporting member in place of a previously disengaged strap member.
Specific examples of the invention are described in more detail below. The reader should understand that these specific examples are set forth merely to illustrate examples of the invention, and they should not be construed as limiting the invention.
The various figures in this application illustrate examples of closure and/or securing systems useful in systems and methods according to examples of this invention. When the same reference number appears in more than one drawing, that reference number is used consistently in this specification and the drawings to refer to the same part throughout.
The sole structure 104 may include several elements. For example, the sole structure 104 may include an outsole member 108 (or other ground-contacting element). This outsole member 108 (or other ground-contacting element) may be made of suitable and conventional materials to provide traction and long wear, and it may be used to protect the foot and/or prevent the remainder of the foot-receiving device structure from wear effects, e.g., when contacting the ground or other surface in use of the footwear product. The sole structure 104 further may include a midsole member 110 that provides impact-attenuating characteristics, e.g., to assist in attenuating the reaction forces to which the wearer's foot would be exposed, for example, when stepping down in the shoe in contact with the ground or other surface. The sole structure 104 further may include an insole member (not shown in the figures), e.g., provided within or adjacent the upper member 102, that provides a comfortable interface for engaging (directly or indirectly) the wearer's foot. The upper member 102 and the sole structure 104, at least in part, may define a foot-receiving chamber of the article of footwear, and this chamber may be accessed by the wearer's foot via opening 106.
The shoe structure 100 as shown in
As described above, the first end 112a of strap member 112 may engage with the upper member 102 and/or the sole member 104 at the toe or mid-foot area of the shoe (on the lateral side of the shoe 100, in the illustrated example). From there, the strap member 112 extends along a portion of the upper member 102 and around the top portion of the foot-receiving chamber of the shoe structure 100. Once on the other side of the upper member 102 (i.e., to the medial side of the shoe structure 100, as shown in
The direction change element 114 may be provided at any desired position and/or in any desired manner, or not at all, without departing from the invention. For example, the direction change element 114 may be provided and/or mounted in the mid-foot or heel area of shoe structure 100, optionally fixedly mounted directly to the upper member 102 and/or a portion of the sole structure 104. As another example, as illustrated in
The direction change element 114 may take on any desired structure without departing from the invention. For example, the direction change element 114 may simply constitute a bar or other mechanical member (e.g., an open rectangular member, as shown in
The direction change member 114 and/or its optional associated strap element 116 may form at least a portion of a strap securing system for this shoe structure 100. The securing system of this example shoe structure 100 further may include a strap securing element 118 that engages and holds the strap member 112. Any desired type of securing element 118 may be used without departing from this invention, including conventional securing elements 118 known in the art, such as buckles, clasps, clamps, cams, hook-and-loop fasteners, or other mechanical devices. In the illustrated example, securing element 118 is clamp or a cam type device in which the strap 112 freely moves through an opening provided when the clamp or cam is in the open position, but the strap 112 is pinched between two portions of the clamp or cam member when the device is closed, thereby holding the strap 112 in place with respect to the securing element 118.
Like the direction change element 114, the securing element 118 may be provided at any desired position and/or in any desired manner without departing from the invention. For example, the securing element 118 may be provided and/or mounted in the mid-foot or heel area of shoe structure 100, optionally fixedly mounted directly to the upper member 102 and/or a portion of the sole structure 104. As another example, as illustrated in
If desired, in accordance with at least some examples of this invention, the strap element 116 for the direction change member 114 and the strap element 120 for the securing element 118 may constitute opposite ends of a single strap member (that extends around the bottom of the foot-receiving chamber (e.g., along a portion of the sole structure)). Alternatively, if desired, the strap elements 116 and 120 may constitute independent and separate elements that are independently and separately engaged with some portion of the shoe structure 100 (e.g., engaged with the upper member 102, the midsole 110, and/or the outsole 108).
Through the use of strap member 112, which wraps around a wearer's foot and engages a securing system (e.g., including a direction change member 114 (optionally mounted on a strap element 116) and a securing element 118 (optionally mounted on a strap element 120) in the illustrated example structure), the shoe structure 100 may be quickly, easily, and securely mounted to a wearer's foot. Moreover, the strap element 112 and securing system may be easily engagable with one another (e.g., using a simple hook-and-loop, clamp, clasp, or cam system) so as to be operable by a child or others that have difficulty tying shoes or operating small mechanical connectors. Optionally, if desired (and if adequate room is available along the length of the shoe 100), the strap member 112 may be wrapped around the wearer's foot multiple times (e.g., two or more times).
As another example, the track elements 122 may be recessed into the upper member 102 as grooves cut into the upper member 102 surface. The track elements 122 may be made of or covered with a material having a low coefficient of friction with respect to (and when directly engaged with) the strap member 112 so that the strap member 112 will be able to more easily move along the track (e.g., during strap tightening or loosening activities, when the foot moves in the shoe, etc.) without excessively wearing or damaging the strap member 112. In other words, if the material or construction of the upper member 102 would cause excessive or rapid wear of the strap member 112 (and/or vice versa), track elements 122 may be provided, at least at some areas along the upper member 102, to help reduce and/or eliminate wear of the strap member 112 and/or the upper member 102. Alternatively or optionally, if desired, the track elements 122 may be provided for purely decorative purposes and/or for other functions without departing from the invention. As noted above, the track elements 122 need not completely cover all areas of the upper member 102 where the strap member 112 is present, although track elements 122 may be provided at all of these locations, if desired. Track elements 122 also may be provided for strap members 116 and 120, if desired, without departing from this invention.
Alternatively or additionally, if desired, rather than providing passageways using separate or independent piece(s) of material 124, the various strap members 112, 116, and/or 120 may be held in place by passageways or tunnels defined directly in the upper member structure 102. Such tunnels or passageways may be defined, for example, by cutting pairs of slits at least partially through the material of the upper member structure 102 to thereby form passageways, wherein a strap member enters the passageway through one slit of the pair and exits through the other slit of the pair.
As shown in
As shown in
If desired, in at least some examples of the invention, the strap member 112 and the groove 110a may be located between the midsole member 110 and the outsole member 108. Alternatively, if desired, all or some portion of the groove 110a may be covered by a cover element 126 that engages with at least one of the upper member 102, the sole member 104, or some other portion of the shoe structure 100 (see
The cover element 126 may be made from any suitable or desired material without departing from the invention. In some examples, the cover element 126 will be constructed from the same material making up at least some portions of the outsole member 108 and will appear similar to the remainder of the outsole member 108. In other examples, if desired, the cover element 126 may be made from plastic or other durable, wear resistant materials, and it may appear as a transparent or translucent window. Optionally, in at least some example structures in accordance with the invention, the cover element 126 may be located between adjacent raised tread elements 108b such that the cover element 126 is recessed somewhat and does not typically directly contact the ground when the shoe 100 is worn.
Also, if desired, the interior surface of the groove 110a may be covered or lined with a material 132 that helps maintain a stable groove or tunnel structure, helps prevent wear of the strap 112 and/or midsole 110, and/or helps maintain a low coefficient of friction between the strap 112 and the groove 110a or other portions of the shoe structure 100. For example, as illustrated in
Of course, footwear products and other foot-receiving devices in accordance with examples of this invention may be produced by securing an upper member (or other foot-covering member) to a sole member (or other foot-supporting member) in any suitable or desired manner, including in conventional manners known and used in the art, such as using adhesives, cements, sewing, fusing methods, mechanical connectors, or the like. The various strap members 112, 116, and/or 120 and their associated elements also may be included in the footwear structures 100 in any desired manner, e.g., using adhesives, cements, sewing, fusing methods, mechanical connectors, and the like.
Finally, while the invention has been described in detail with references to an article of footwear, those skilled in the art will appreciate that advantageous aspects of the invention also may be applied to other foot-receiving device products.
Various examples of the present invention have been described above, and it will be understood by those of ordinary skill that the present invention includes within its scope all combinations and subcombinations of these examples. Additionally, those skilled in the art will recognize that the above examples simply exemplify the invention. Various changes and modifications may be made without departing from the spirit and scope of the invention, as defined in the appended claims.
