Description

BACKGROUND OF THE INVENTION

This present invention relates to articles of footwear, and more particularly to an upper assembly that is selectively alterable to offer different visual effects.
There are a variety of footwear that include features that are able to be modified to change the aesthetics of the footwear. For example, there are certain women's shoes, including vamps that are adapted to accept a separate, supplemental panel. The supplemental panel also can be removed and replaced with another panel to provide different coloration, designs or the like to those shoes.
There also are shoes and sandals that include a reversible panel which is linked via a cord to an upper construction. The panel can include a front side and a reverse side. The panel can be swiveled about the cord to selectively expose either the front side or the reverse side to provide a desired visual coloration, design or image. This construction can provide variety to the user and enable them to select a particular design depending on their disposition at the time.
While the above can enable a user, such as a child, to modify the appearance of footwear, there remains room for improvement in the field.

SUMMARY OF THE INVENTION

A footwear and upper assembly are provided including a panel or strap joined with the upper, where the panel or strap is selectively moveable to expose a first indicia element, while concealing a second indicia element, or to expose a second indicia element, while concealing the first indicia element.
In one embodiment, footwear includes an outsole and an upper joined with the outsole. The upper includes an exterior surface. A panel is joined with the upper. The panel is foldable about an axis between a first position and a second position. A first indicia element is exposed when the panel is in the first position, and a second, different indicia element is exposed when the panel is in the second position.
In another embodiment, footwear includes an outsole and an upper joined with the outsole. The upper defines a foot void that is adapted to receive a wearer's foot. The upper has an exterior surface with a curved contour. The upper also includes a panel joined with the upper adjacent the curved contour of the exterior surface. The panel is pivotable about an axis which follows the curved contour, and is generally curved itself. Additionally, the panel is urged to either a first position or a second position due to the attachment of the panel to the curved contour. A first indicia element is exposed when the panel is in the first position, and a second indicia element is exposed when the panel is in the second position.
In still another embodiment, footwear includes an outsole and an upper joined with the outsole. The upper includes an exterior surface having a curved contour, and a panel is joined with the upper adjacent the curved contour. The panel has a first edge and a second edge and is pivotable about an axis between a first position and a second position. The axis follows the curved contour of the upper and is curved itself. The panel exposes a first indicia element in the first position, while concealing a second indicia element in the first position, and exposes a second, different indicia element in the second position, while concealing the first indicia in the second position.
In even another embodiment, the panel is of a first curved configuration from the first edge to the second edge when in the first position, and is of a second curved configuration from the first edge to the second edge when in the second position. The panel moves through an intermediary position as it transitions to at least one of the first position and the second position and is urged to achieve at least one of the first curved configuration and the second curved configuration as it moves through the intermediary position. The panel snaps into either the first curved configuration or the second curved configuration in the first position and in the second position, respectively, generally following the curved contour of the exterior surface in the first position and the second position.
In a further embodiment, a footwear upper assembly defines a foot void and includes a lateral panel and a medial panel. The lateral panel defines a first slot, and the medial panel defines a second slot, where the first and second slots are disposed on opposing sides of the footwear. The upper assembly also includes a closure strap that extends through the first slot and the second slot. The strap is configured to snugly secure a wearer's foot within the foot void. The strap is slidably moveable relative to the first and second slots to a first position and to a second, different position.
In still a further embodiment, a first indicia element is exposed when the strap is in the first position, and a second, different indicia element in exposed when the strap is in the second position. The strap includes a first end and a second end configured so that either the first end is secured to the medial panel when the first indicia element is exposed, or the second end is secured to the lateral panel when the second indicia element is exposed.
In yet a further embodiment, a footwear upper assembly includes a vamp, a lateral quarter panel, a medial quarter panel, and a strap. The lateral quarter panel defines a first slot and is joined with the vamp. The medial quarter panel defines a second slot and is joined with the vamp. The first and second slots are disposed on opposing sides of the footwear. The strap extends through the first slot and the second slot and is configured to snugly secure a wearer's foot within the foot void. The strap is slidably moveable relative to the first and second slots to a first position and to a second, different position.
In even a further embodiment, a first indicia element is exposed when the strap is in the first position, and a second, different indicia element in exposed when the strap is in the second position. The strap includes a first end, a second end, and a center portion between the first and second ends. The first end includes a first closure device, the second end includes a second closure device, the center portion includes a third closure device, the lateral quarter panel includes a fourth closure device, and the medial quarter panel includes a fifth closure device. In the first position, the first closure device is secured to the third closure device to secure the first end to the center portion, and the second closure device is secured to the fourth closure device to secure the second end to the lateral quarter panel. In the second position, the second closure device is secured to the third closure device to secure the second end to the center portion, and the first closure device is secured to the fifth closure device to secure the first end to the medial quarter panel.

DETAILED DESCRIPTION OF THE CURRENT EMBODIMENTS

An article of footwear in accordance with a current embodiment is shown in FIGS. 1-3 and generally designated 10. The article of footwear 10 generally includes an upper assembly 12 joined with an outsole 14. The upper assembly 12 and the outsole 14 together define a foot void 16 configured to securely and comfortably hold a human foot. The foot is received through a foot opening 17 defined by the upper assembly 12. The upper assembly 12 and the outsole 14 each have a corresponding forefoot portion, a heel portion, a lateral portion, and a medial portion.
Although the embodiments are illustrated in the context of a children's athletic or play shoe, it may be incorporated into other adolescent or adult shoes, and any type or style of footwear, including shoes, boots and sandals. It 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 (i.e. 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 orientations.
For purposes of disclosure, the embodiments are described in the context of the footwear 10 including the outsole 14. The upper assembly 12, may, however, be combined with any type or style of sole construction capable of being suitably joined with the upper assembly 12. The upper assembly 12 of the illustrated embodiment includes an upper 18 including an exterior surface having a curved contour, the upper 18 formed from one or more layers of material that are shaped to form an enclosure of roughly the size and shape of a wearer's foot, defining the foot void 16. The upper 18 includes medial and lateral side or quarters 20, 22 in a spaced relationship disposed on opposite sides of the footwear and the wearer's foot, and a contoured vamp 24 that closes a portion of the top of the upper 18. Foxing and other trim or extra material may be added to the upper 18 as desired for functional or aesthetic reasons. In this embodiment, the upper 18 includes a tongue 26 to facilitate fitting and removal of the article of footwear 10 on the wearer's foot. The tongue 26 and outsole 14 generally are conventional and therefore will not be described in detail herein. Additionally, the upper 18 may include a heel counter 19. The heel counter 19 may be a generally conventional heel counter configured to provide control and stability to the wearer's heel.
The upper 18 includes a closure strap 28 that is disposed over the curved exterior surface of the upper 18 and configured to snugly secure a wearer's foot within the foot void 16. The strap 28 has a first end 30 attached to one of the medial quarter 20 or the lateral quarter 22 of the upper assembly 12 near the foot opening 17. The strap 28 also includes a free second end 32 that is releasably securable to the other of the lateral and medial quarters 20, 22 (that is, the opposite side) of the upper 18. The second end 32 of the strap 28 may be releasably securable to the opposite lateral or medial quarter 20, 22 by a mating releasable fastener, such as hook and loop fasteners (for example, Velcro® fasteners), a buckle, snaps, magnets, a friction device, or any other suitable device capable of temporarily fastening one footwear component to another. One side of the mating releasable fastener is located on each of the second end 32 of the strap 28 and the opposite lateral or medial quarter 20, 22.
The strap 28 also includes a decorative panel 40 that is foldable/pivotable between a first position A, shown in FIG. 1, and a second, different position B, shown in FIG. 3. The terms fold, pivot, and flip are used herein to describe the action of repositioning or moving the panel 40 from one position to expose or conceal one or more indicia elements, to another position to expose or conceal one or more other indicia elements. When folded, the panel 40 is bent over upon itself along a fold line or crease. When pivoted, at least a portion of the panel 40 rotates or turns about an axis or point. Further, the action of folding may be considered a specific form of pivoting with respect to the footwear described herein. Optionally, the panel 40 is positioned on the strap 28 or the tongue 26 and is located a predetermined distance below the upper extremity of the tongue 26 or the uppermost portion of the upper 18 so that the panel 40 does not engage an ankle of the wearer as the wearer engages in activity, such as running, walking, or crawling.
The panel 40 is made up of a first stationary portion 42, a first pivoting portion 44, a second stationary portion 46, and a second pivoting portion 48. In the illustrated example, the first stationary and pivoting portions 42, 44 are generally halves of a rectangular piece of material. It should be understood, however, that the piece of material may have a shape other than a rectangle, and may be effectively split into portions other than halves. Likewise, the second stationary and pivoting portions 46, 48 are generally halves of a second rectangular piece of material. The stationary portions 42, 46 are positioned adjacent and in alignment with one another, and optionally are joined with the strap 28. Of course, the stationary and pivoting portions can be joined with other elements of the footwear as desired. The stationary portions 42, 46 can be joined with the strap 28 by stitching, adhesive, or any other suitable means. Additionally, the stationary portions, 42, 46 are arranged such that the pivoting portions 44, 48 are aligned back-to-back. The pivoting portions 44, 48 are secured together and define a panel portion 50 that is pivotable about an axis 51 between the first and second positions A and B. The pivoting portions 44, 48 can be secured together via stitching, adhesive, or any other suitable means. In the illustrated example, the axis 51 or fold line is perpendicular to a longitudinal axis LA, shown in FIG. 2, and is formed by the lower edge of the panel portion 50 where the pivoting portions 44, 48 transition to the stationary portions 42, 46.
The panel 40 includes a first indicia element 52 and a second indicia element 54. The first indicia element 52 is visible when the panel portion 50 is flipped, pivoted, moved, or transitioned to the first position A, and the second indicia element 54 is visible when the panel portion 50 is flipped to the second position B. In the illustrated example, the first indicia element 52 is illustrated simply as a square and the second indicia element 54 is illustrated simply as a circle. It should be understood that any desirable graphic, word, phrasing, image, etc. may be used as the indicia forming or in relationship to an indicia element. Further, as is perhaps best seen in FIG. 2, portions of the indicia may extend across both the first stationary and pivoting portions 42, 44, and the second stationary and pivoting portions 46, 48, each portion 42-48 forming a fraction of the respective indicia. Of course, it should also be understood that the entire indicia may be contained entirely on any one of the portions.
With the described panel 40 configuration, the panel portion 50 can be pivoted, as illustrated by arrow C in FIG. 2, between the first and second positions A and B, to reveal one of the first and second indicia elements 52, 54. Accordingly, when flipped to the first position A, the panel portion 50 covers the second stationary portion 46, and together the first stationary portion 42 and the panel portion 50 reveal the first indicia element 52. Oppositely, when flipped to the second position B, the panel portion 50 covers the first stationary portion 42, and together the second stationary portion 46 and the panel portion 50 reveal the second indicia element 54. In the illustrated example, the panel portion 50 is flipped up (away from the outsole) or down (toward the outsole).
The pivoting of a member about an arcuate axis creates a biasing force by causing the pivot axis to straighten at the base of the pivoting member, thereby urging the member to a position where the axis is again arcuate. In the illustrated embodiment, the non-rigid strap 28 conforms to the curved exterior surface of the upper 18, and the panel 40, being joined with the upper 18 adjacent the curved contour, is also curved in a direction between the medial and lateral portions of the upper 18. Further, the pivot axis 51 follows the curved contour and is also generally curved about the longitudinal axis LA. Stated differently, the pivot axis is curved downward such that the center is the highest point, and the medial and lateral ends are the lowest points. The curvature of the panel 40 provides a bias when moving the panel portion 50, for example by flipping it, thereby urging the panel portion 50 to one of the first or second positions A or B due to the attachment of the panel 40 to the curved contour. Moreover, the greater the degree of curvature, the greater the bias toward one of the first or second positions A or B. Additionally, the panel portion 50 may include a fastener 56 to releasably maintain the panel portion 50 in either of the first or second positions A or B. It is contemplated that the fastener 56 may be in the form of a magnet, hook and loop, or any other suitable type fastener.
This phenomenon of creating a bias when pivoting a member about an arcuate axis can be described in another manner. For example, the panel 40 is joined with the upper 18 adjacent the curved contour of the exterior surface and is pivotable about the axis 51, between first position A and second position B. Additionally, the panel 40 includes a first edge 40 a and a second edge 40 b, as shown in FIG. 1. In the first position A, shown in FIG. 1, the panel is of a first curved configuration from the first edge 40 a to the second edge 40 b. Referring now to FIG. 3, the panel 40 is of a second curved configuration from the first edge 40 a to the second edge 40 b when in the second position B. The first curved configuration can be described as having a concave form when considering the shape of the upper surface of the panel 40 relative to the longitudinal axis LA. Conversely, the second curved configuration can be described as having a convex form when considering the shape of that same upper surface of the panel 40 when in the second position B. In the second position B, the upper surface of the panel 40 is folded in half, upon itself. In this arrangement, the second curved configuration is convex relative to the longitudinal axis LA. Further, when the panel 40 moves through an intermediary position, as shown in FIG. 2, as it transitions to one of the first and second positions A and B, the panel 40 is urged to achieve at least one of the first and second curved configurations. As such, the panel 40 snaps into either the first curved configuration or the second curved configuration in the first position A and in the second position B, respectively, generally following the curved contour of the exterior surface in the first position A and the second position B. Additionally, this urging or bias retains the panel 40 in the user-selected position and the panel portion 50 remains either up or down, in either the first or second positions A or B, during normal activity as performed by the wearer.
Alternately, it should be noted that a user may release the strap 28 from the fastener on the lateral or medial quarter 20, 22 before pivoting the panel portion 50 from one position to the other. The released strap 28 can be straightened, thereby removing the curvature and bias from the pivot axis 51. The panel portion 50 may be flipped to the desired position, and the strap 28 may then be again secured to the fastener on the lateral or medial quarter 20, 22, returning the curvature and bias to the pivot axis 51 and the panel portion 50.
A first alternative embodiment of the footwear is illustrated in FIGS. 4-6 and generally designated 110. This first alternative embodiment is similar to the embodiment above with a few exceptions. For example, the strap 128 includes at least two layers: a first layer 170 having a void, recess, or cutout 172, the first layer including an integral panel portion 150, and a second layer 176 positioned behind the first layer 170. The panel portion 150 has a first side 178 and a second side 180 and is pivotable between the first and second positions A and B.
As shown, a lower portion of the first indicia element 152 is included on the first layer 170. Additionally, an upper portion of the second indicia element 154 is included on the second layer 176 and is positioned within the cutout 172. When in the first position A, as shown in FIG. 4, the first side 178 of the panel portion 150 and the first layer 170 together expose or illustrate the entire first indicia element 152. Additionally, in the first position A, the panel portion 150 conceals the second indicia element 154. In the second position B, as shown in FIG. 6, together the second side 180 of the panel portion 150 and the second layer 176 of the strap 128 reveal the second indicia element 154 and conceal the first indicia element 152. Accordingly, in the second position B, the first layer 170 and the second layer 176 are aligned such that the respective portions of the second indicia element 154 are aligned. As discussed above with respect to other embodiments herein, the panel portion 150 is biased toward one of the first and second positions A and B by way of its attachment to the upper assembly and/or the construction of the curved pivot axis 151.
A second alternative embodiment of the footwear is illustrated in FIGS. 7-9 and generally designated 210. This second alternative embodiment is similar to the embodiments above with a few exceptions. For example, the strap 228 is made of two layers: the first layer 270 having a void 272, and the second layer 276 positioned behind the first layer 270. A panel 240 is joined atop the first layer 270 of the strap 228. The panel 240 includes a stationary portion 242 and a pivoting portion that defines a panel portion 250. The panel portion 250 has a first side 278 and a second side 280 and is pivotable between the first and second positions A and B.
As shown, the first indicia element 252 is provided across both the stationary portion 242 of the panel 240 and the first side 278 of the panel portion 250. Thus, when in the first position A as shown in FIG. 7, the stationary portion 242 and panel portion 250 show the first indicia element 252. An upper portion of the second indicia element 254 is included on the second layer 276 and positioned within the void 272. Therefore, in the second position B, as shown in FIG. 9, together the second side 280 of the panel portion 250 and the second layer 276 of the strap 228 reveal the second indicia element 254. Accordingly, in the second position B, the first layer 270 and the second layer 276 are aligned such that the portions of the second indicia element 254 are aligned. As discussed above with respect to other embodiments herein, the panel portion 250 is biased toward one of the first and second positions A and B by the curved pivot axis 251.
A third alternative embodiment of the footwear is illustrated in FIGS. 10-12 and generally designated 410. This third alternative embodiment is similar to the embodiments above with a few exceptions. For example, the panel 440 is similar in construction and functionality to the panel 40 of FIGS. 1-3, except that the stationary portion 442 of panel 440 extends along substantially the entire length of the strap 428, from a medial side 420 of the shoe to the lateral side 422 of the shoe. The pivoting portion 444 can be integral with the panel 440 and disposed on a lower edge of the stationary portion 442. The stationary portion 442 transitions to the pivoting portion 444 along the pivot axis 451. Optionally, the panel 440 can be primarily in the central third or half of the strap, generally centered over the tongue 426.
A fourth alternative embodiment of the footwear is illustrated in FIGS. 13-15 and generally designated 510. This fourth alternative embodiment is similar to the embodiments above with a few exceptions. For example, the alternate strap 528 includes a panel 540 made up of a stationary portion 542 and a pivoting portion 544. The stationary portion 542 can be of substantially the same dimensions as the strap 528. The pivoting portion 544 can be integral with the panel 540 and disposed on a lower edge of the stationary portion 542. The stationary portion 542 transitions to the pivoting portion 544 along the pivot axis 551. Optionally, pivoting portion 544 can be folded over part or all of the stationary portion 542 when in the first position A as shown in FIG. 13. A first indicia element 552 can be included on a first side 578 of the pivoting portion 544, and a second indicia element 554 can be included on a second side 580 of the pivoting portion 544. When the pivoting portion 544 is folded up about the pivot axis 551 to a first position A, a first indicia element 552 is visible, and a second indicia element 554 is concealed. When the pivoting portion 544 is folded down about the pivot axis 551 to a second position B, the second indicia element 554 is visible, and the first indicia element 552 is concealed. In this second position B, the pivoting portion 544 extends below the strap 528 and the second indicia element 554 may extend across both the second side 580 of the pivoting portion 544 and the previously concealed portion of the stationary portion 542. Of course, it should be understood that the pivoting portion 544 may be formed of a separate piece of material and can be joined with the strap 528 or panel 540 by stitching, adhesive, or any other suitable means. Additionally, the strap 528 and the panel 540 may be formed by a single layer of material such that the panel 540 functions as the strap 528.
Referring now to FIG. 16 an fifth alternative embodiment of footwear 10′ including an alternate upper 18′ having multiple panels 40′ is illustrated. The alternative panel may include multiple panel portions 50′ that are foldable about the axis 51′ in a booklet-style configuration. This fifth alternative embodiment enables multiple indicia elements 52′, 54′ to be included with the footwear 10′. The illustrated example includes three panel portions 50′, however, it should be understood that substantially any number of panel portions 50′ may be included.
Generally, in the embodiments illustrated in FIGS. 1-15, the panel is disposed on the vamp portion of the upper, and more specifically on the closure strap of the upper. Optionally, the panel may be positioned on substantially any curved surface of the upper. For example, the panel may be joined with the upper on a curved exterior surface of any one or all of the vamp, the heel counter, and the toe box. Referring to FIG. 17, implementation of a sixth alternative embodiment of the footwear 10″ with an alternate panel 50″ is shown positioned on the heel counter 19″. It should be noted that the panel may be positioned on the alternate locations in addition to, or instead of, the previously described embodiments. In other words, a single panel may be positioned on any one of the vamp, heel counter, or toe box; or multiple panels may be positioned on any combination of these locations. For example, an alternate panel may be positioned atop the toe box such that its pivot axis is parallel to the longitudinal axis LA and the alternate panel portion flips between medial and lateral sides of the footwear.
Referring now to FIG. 18, a seventh alternative embodiment of footwear 10′″ including an alternate upper 18′″ having multiple panel portions 50′″ is illustrated. The alternative multiple panel portions 50′ may be folded in an accordion-style booklet configuration. This seventh alternative embodiment enables multiple indicia elements 52′″, 54′″, 55′ to be included with the footwear 10′″. The panel portions 50″ may be pulled away from their biased position A or B, and the arrangement of the panel portions 50′″ may be altered to display different indicia elements or combinations of indicia elements.
