The present disclosure relates to rapid-entry footwear having a compressible lattice structure.
Whether due to inconvenience or inability, donning and doffing of shoes, including tying or otherwise securing the same, may be undesirable and/or present difficulties to some individuals. The present disclosure addresses this need.
Disclosed herein, in various embodiments, is a rapid-entry shoe having a compressible lattice structure to facilitate easy donning and doffing of shoes. The compressible lattice structure may bias the rapid-entry shoe from an open position toward a closed position. The open position may have an expanded shoe opening to facilitate reception of a foot of an individual wearing the rapid-entry shoe, while the closed position may have a smaller shoe opening to retain the foot within the rapid-entry shoe. Embodiments of various compressible lattice structures are described herein, as is a yoke for use with a rapid-entry shoe.
The accompanying drawings may provide a further understanding of example embodiments of the present disclosure and are incorporated in, and constitute a part of, this specification. In the accompanying drawings, only one rapid-entry shoe (either a left shoe or a right shoe) may be illustrated, however, it should be understood that in such instances, the illustrated shoe may be mirror-imaged so as to be the other shoe. The use of like reference numerals throughout the accompanying drawings is for convenience only, and should not be construed as implying that any of the illustrated embodiments are equivalent. The accompanying drawings are for purposes of illustration and not of limitation.
Example embodiments of the present disclosure are described in sufficient detail in this detailed description to enable persons having ordinary skill in the relevant art to practice the present disclosure, however, it should be understood that other embodiments may be realized and that mechanical and chemical changes may be made without departing from the spirit or scope of the present disclosure. Thus, this detailed description is for purposes of illustration and not of limitation.
For example, unless the context dictates otherwise, example embodiments described herein may be combined with other embodiments described herein. Similarly, references to “example embodiment,” “example embodiments” and the like indicate that the embodiment(s) described may comprise a particular feature, structure, or characteristic, but every embodiment may not necessarily comprise the particular feature, structure, or characteristic. Moreover, such references may not necessarily refer to the same embodiment(s). Any reference to singular includes plural embodiments, and any reference to plural includes singular embodiments.
Any reference to coupled, connected, attached or the like may be temporary or permanent, removeable or not, non-integral or integral, partial or full, and may be facilitated by one or more of adhesives, stitches, hook and loop fasteners, buttons, clips, grommets, zippers and other means known in the art or hereinafter developed.
As used herein, the transitional term “comprising”, which is synonymous with “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. The transitional phrase “consisting of” excludes any element, step, or ingredient not specified in the claim. The transitional phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps “and those that do not materially affect the basic and novel characteristic(s)” of the claimed invention.
No claim limitation is intended to invoke 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph or the like unless it explicitly uses the term “means” and includes functional language.
In describing example embodiments of the rapid-entry footwear, certain directional terms may be used. By way of example, terms such as “right,” “left,” “medial,” “lateral,” “front,” “back,” “forward,” “backward,” “rearward,” “top,” “bottom,” “upper,” “lower,” “up,” “down,” and the like may be used to describe example embodiments of the rapid-entry footwear. These terms should be given meaning according to the manner in which the rapid-entry footwear is most typically designed for use, with the rapid-entry footwear on a user's foot and with the user's shod foot disposed on or ready for placement on an underlying surface. Thus, these directions may be understood relative to the rapid-entry footwear in such use. Similarly, as the rapid-entry footwear is intended primarily for use as footwear, terms such as “inner,” “inward,” “outer,” “outward,” “innermost,” “outermost,” “inside,” “outside,” and the like should be understood in reference to the rapid-entry footwear's intended use, such that inner, inward, innermost, inside, and the like signify relatively closer to the user's foot, and outer, outward, outermost, outside, and the like signify relatively farther from the user's foot when the rapid-entry footwear is being used for its intended purpose. Notwithstanding the foregoing, if the foregoing definitional guidance is contradicted by an individual use herein of any of the foregoing terms, the term should be understood and read according to the definition that gives life and meaning to the particular instance of the term.
As used herein, a “rapid-entry shoe” refers to an athleisure shoe, a casual shoe, a formal shoe, a dress shoe, a heel, a sports/athletic shoe (e.g., a tennis shoe, a golf shoe, a bowling shoe, a running shoe, a basketball shoe, a soccer shoe, a ballet shoe, etc.), a walking shoe, a sandal, a boot, or other suitable type of shoe. Additionally, a rapid-entry shoe can be sized and configured to be worn by men, women, or children.
In various embodiments, and with reference to
In example embodiments, the lattice structure 110 disclosed herein is not merely a common fabric/textile material, but instead is a material that is capable of being reversibly compressed such that it recoils back up after the foot/heel of the user is no longer applying the downward compressive force. For example, the lattice structure 100 may be made from or comprise a polymer material, a metallic material, or a composite material, among others.
In example, embodiments, the open area defined by apertures 112 is greater than the closed area defined by lattice structure 110 itself. The one or more apertures 112 of lattice structure 110 can have various shapes. For example, the one or more apertures 112 can each have a diamond-like shape or any other elliptical, non-elliptical, or random shape, as illustrated in
As used herein, an “elliptical” shape refers to any shape that generally lacks a point where two lines, curves, or surfaces converge to form an angle. For example, an “elliptical” shape encompasses traditional Euclidian geometric shapes such as circles and ellipses, as well as other non-angular shapes (that lack any angles), even if those shapes do not have designations common in Euclidian geometry.
As used herein, a “non-elliptical” shape refers to any shape that includes at least one point where two lines, curves, or surfaces converge to form an angle. For example, a “non-elliptical” shape encompasses traditional Euclidian geometric shapes such as triangles, rectangles, squares, hexagons, trapezoids, pentagons, stars, and the like as well as other shapes that have at least one angle even if those shapes do not have designations common in Euclidian geometry.
Apertures 112 can be consistent throughout lattice structure 110 or different throughout lattice structure 110, for example, progressively changing in size and/or shape between sides, larger toward the bottom, larger toward the top, etc. Apertures 112 can be cut into a material to form lattice structure 110. Alternatively, apertures 112 can be molded. More generally, apertures 112 are defined as the open areas between the plurality of interconnected, overlapping, intersecting and/or woven ribs.
Compressible lattice structure 110 can be molded, 3D printed or otherwise formed substantially flat (e.g., as illustrated in
In other embodiments, apertures are separated from one another by one or more folds, pleats, surface grooves and/or surface channels (e.g., a recess in the surface of a material). In yet other embodiments, apertures are separated from one another by one or more weakened portions of the compressible lattice structure 110, the relative weakness being due to at least one of a differing thickness and a differing material.
In still other embodiments, apertures themselves are comprised of folds, pleats, surface grooves or surface channels (e.g., a recess in the surface of a material). In yet other embodiments, apertures themselves are comprised of weakened portions of the compressible lattice structure 110, the relative weakness being due to at least one of a differing thickness and a differing material.
Generally, the compressible lattice structure 110 enables the rapid-entry shoe 100 to transition between an open position and a closed position in a resilient manner. For example, and with reference to
In various embodiments, the rapid-entry shoe 100 may, by default, be in the closed position (e.g., may be biased toward the closed position). Accordingly, a downward force on the lattice structure 110 (e.g., exerted by a user's heel) may compress the lattice structure 110 to collapse the plurality of apertures 112 to lower the heel portion of the shoe to the open position and thereby expand the shoe opening (through which a user's foot is inserted). Accordingly, the lattice structure may bias the rapid-entry shoe 100 toward the closed position such that in absence of a compression force driving the lattice structure 110 toward the open position, the rapid-entry shoe 100 is in the closed position.
In various embodiments, the rapid-entry shoe 100 may not necessarily be biased toward either the open or closed position. For example, the rapid-entry shoe 100 may be bi-stable and thus may be configured to have stability in both the open and closed positions. In various embodiments, stability in the open position may be accompanied by an engagement or interlocking mechanism that temporarily secures the lattice structure 110 in the collapsed state, or by other means known in the art or hereinafter developed.
Thus, as described, the compressible lattice structure 110 is generally configured to enable the heel portion of the rapid-entry shoe 100 to be collapsed downward toward the base without deflecting inward toward a shoe opening.
As used herein, a “base” of a rapid-entry shoe refers to an outsole or portions thereof, a midsole or portions thereof, an insole or portions thereof, a wedge or portions thereof, or other suitable structure disposed between and/or adjacent to the foregoing parts of a rapid-entry shoe.
In various embodiments, and with continued reference to
In some embodiments, the stabilizer may be coupled to an upper edge of the compressible lattice structure 110 or the upper, and the stabilizer may prevent (or at least limit) deflection of the heel portion (e.g., the compressible lattice structure 110) of the rapid-entry shoe inward into a shoe opening. In some embodiments, the stabilizer may be integral with the lattice structure, e.g., a continuous section/portion of the lattice structure. That is, the stabilizer may be a portion/section of the lattice structure that, for example, has a higher mechanical rigidity, or is otherwise configured to prevent inward deflection of the heel portion of the shoe.
Whether coupled to or integral with the lattice structure 110, the stabilizer 120 may be completely positioned above the lattice structure 110 of rapid-entry shoe 100 (
In various embodiments, the stabilizer 120 is made from a stiff material or soft material that is assembled in a way to provide stiffness. The stabilizer 120 can be molded onto an outsole of the rapid-entry shoe 100 and then glued or otherwise coupled to the upper, or the stabilizer 120 may be made as a part of the upper and glued or otherwise coupled to the outsole. In various embodiments, the stabilizer 120 and/or the lattice structure 110 may include an overmold or other polymer or textile covering (including the shoe upper or a portion thereof) to minimize discomfort experienced by an individual wearing the shoe.
In some embodiments, the stabilizer 120 is v-shaped, u-shaped, horse-shoe-shaped (with consistent or inconsistent curvature as it rounds the rear portion of the rapid-entry shoe 100), or otherwise has an elongated shape, and thus wraps around an upper rear portion of the rapid-entry shoe 100 and/or may be connected across the back of the shoe. In other embodiments, the stabilizer may include two separate parts extending forward from the rear of the shoe, as discussed herein with reference to
Accordingly, the rapid-entry shoe 100 may have a collapsible rear heel, that is prevented from buckling inwards into the foot area of the rapid-entry shoe when the heel of the rapid-entry shoe is compressed in the open position.
In various embodiments, the plurality of apertures 112 defined by the compressible lattice structure 110 are voids that accommodate the compression, and the lattice structure 110 may also provide a recoil pressure to push the heel portion of the rapid-entry shoe 100 upwards away from the base/sole, thereby enabling the lattice structure 110 to facilitate retention of the foot within the shoe. In various embodiments, the recoil or rebound may be partially or fully provided by the lattice structure 110.
In various embodiments, one or more of the apertures 112 of the lattice structure 110 of rapid-entry shoe 100 can be filled. For example, the apertures 112 of the lattice structure 110 can be filled with a lattice substructure 130 (as illustrated in
In some embodiments, the lattice structure is in contact with the base of rapid-entry shoe continuously along an edge of the lattice structure (as illustrated in
In some embodiments, and with reference to
In example embodiments, a plurality of larger ribs are generally concave toward the rear portion of the base of rapid-entry shoe 100, while a plurality of smaller, interconnected, overlapping, intersecting and/or woven ribs are generally convex toward the rear portion of the base of rapid-entry shoe 100.
In connection with example embodiments, ribs that are generally concave toward the rear portion of the base of rapid-entry shoe 100 may be shorter closer to the base, while ribs that are generally convex toward the rear portion of the base of rapid-entry shoe 100 may be longer closer to the base.
In example embodiments, a plurality of larger ribs are generally angled upward toward the rear portion of rapid-entry shoe 100, while a plurality of smaller, interconnected, overlapping, intersecting and/or woven ribs are generally angled downward toward the rear portion of rapid-entry shoe 100.
With specific reference to
In accordance with example embodiments comprising structure described herein, lattice structure 110 can be configured such that ribs 111 located further from the base collapse before ribs 111 located closer to the base.
In various embodiments, and with continued reference to
In various embodiments, the lattice structure 110 has one or more flanges that can be stitched, glued, molded directly or otherwise coupled to the upper, midsole or outsole, e.g., an upper flange coupled to the upper, and a lower flange coupled between the upper and either the midsole or the outsole. With reference to
Additional embodiments of lattice structures 110 comprising upper flanges 165 and/or lower flanges 160 are shown in
With reference now to
In some embodiments, a yoke extends upward to a greater distance from the base than the distance of the surrounding topline (collar) of the upper from the base. In some embodiments, a yoke extends upward to a greater distance from the base than the distance of the top edge of the tongue from the base. While a yoke 150 can be coupled to and extend in an upward direction from a lattice structure 110 and/or stabilizer as described herein (
In some embodiments, the yoke 150 is further configured to expand an opening of a lattice structure 110. A foot being directed into a lattice structure 110 of a rapid-entry shoe 100 is illustrated in
The yoke 150 may be made from a polymer material, a metallic material, or a composite material, among others. The yoke 150 may be comprised of a material exhibiting stiffness, such that it is not compressed when the heel portion (and the lattice structure) is compressed downward toward a base of the rapid-entry shoe. In other embodiments, the yoke 150 could be comprised of a material exhibiting flexibility. In still other embodiments, the yoke 150 could be comprised of a material exhibiting stiffness with a soft covering, e.g., for comfort. The yoke 150 and the lattice structure 110 may be a unitary structure (e.g., formed from a common mold).
The present disclosure thus comprises a rapid-entry shoe having a heel portion and a yoke coupled to it, wherein in an open position the heel portion is compressed downward toward a base of the rapid-entry shoe, and in a closed position the heel portion is expanded, wherein the rapid-entry shoe is biased toward the closed position, and wherein the yoke is configured to direct a foot into the rapid-entry shoe.
