RELATED ORDER DATA
[001] This application claims priority for patent application No. US 13 / 744,052, entitled "Easy Access Articles of Footwear" and filed on January 17, 2013. Patent application No. US 13 / 744,052, in its all, is incorporated by reference in this document. FIELD OF THE INVENTION
[002] The present invention relates to the footwear field. More specifically, aspects of the present invention pertain to footwear articles that include foot insertion openings capable of widely opening the side (s) and / or rear area (s) of the shoe to allow easy insertion and the easy removal of a foot. The upper parts of shoes with large openings of this type can be particularly useful for high-top athletic shoes, boots or other shoe structures that extend up to or at least partially over the wearer's ankles. BACKGROUND
[003] Conventional athletic shoe items include two main elements, an upper and a sole structure. The upper part can provide a cover for the foot that securely receives and positions the foot in relation to the sole structure. In addition, the upper part can have a configuration that protects the foot and provides ventilation, thereby cooling the foot and removing perspiration. The sole structure can be attached to a lower surface of the upper and is usually positioned between the foot and any contact surface. In addition to attenuating ground reaction forces and absorbing energy, the sole structure can provide traction and control potentially damaging foot movement, such as overpronation. The general features and configurations of upper parts and sole structures are discussed in more detail below.
[004] The upper part forms an empty space inside the shoe to receive the foot. The empty space has the general shape of the foot and access to the empty space is provided in an ankle opening. Accordingly, the upper part extends over the instep and toe areas, along the intermediate and lateral sides of the foot, and around the heel area of the foot. A shoelace system is often incorporated into the upper to selectively change the size of the ankle opening and to allow the user to modify certain dimensions of the upper, particularly circumference, to accommodate the feet in varying proportions. In addition, the upper part may include a tongue that extends under the lacing system to accentuate the comfort of the shoe (for example, to modulate the pressure applied to the foot by the laces), and the upper part may also include a heel stop. to limit or control movement of the heel.
[005] Some footwear articles, particularly footwear with uppers that extend up to the ankle or over the ankle (also called "high-top" shoes in the present invention, for example, basketball shoes with "high-top" "or other athletic shoes, professional shoes, boots and the like), can be difficult to put on and remove. If the shoes have laces or similar over the instep area, the user may be required to substantially loosen the laces (or other gripping mechanisms) to allow the shoes to be easily placed and / or removed. These features can substantially increase the time and level of frustration involved in putting on and taking off "tall" shoes.
[006] Accordingly, there is a need in the art for improvements in systems to allow easy entry, removal and / or gripping of "tall" shoes on users' feet. SUMMARY OF THE INVENTION
[007] This Summary is provided to introduce some general concepts related to this invention in a simplified way, which are further described below in the Detailed Description. This Summary is not intended to identify the key features or essential features of the invention.
[008] Footwear structures according to at least some aspects of this invention may include foot insertion openings that widely open the side (s) and / or rear area (s) of the shoe (e.g. , the upper part) to allow easy insertion and easy removal of a foot.
[009] Some more specific aspects of this invention refer to footwear articles that may include: (a) an upper part that has or that defines an opening through which a user's leg extends, in which the upper part additionally includes a foot insertion opening that extends back and down from a front portion of the leg opening at least to an upper heel area; (b) a closing system for releasably closing the foot insertion opening; and (c) a sole structure engaged at the top. The closure system may additionally include one or more of: (a) a strip that extends at least partially around the leg (for example, along the front) and releasably attaches to the upper part, (b) a lace (optionally attached to the strap via an elastic component) that extends through the instep area one or more times and / or (c) one or more elastic elements that extend through the instep area of the upper part . The closure system may include structures to tighten the shoe fitting around and secure the shoe to the user's foot.

[018] In the following description of several examples of shoe structures and components according to the present invention, reference is made to the attached drawings, which form a part of it, and in which are shown, by way of illustration, several examples of structures and environments in which aspects of the invention can be put into practice. It should be understood that other structures and environments can be used and that structural and functional modifications can be made to the structures and methods specifically described without departing from the scope of the present invention. I. General Description of Aspects of this Invention
[019] Aspects of this invention relate to footwear articles (for example, athletic shoes) that include foot insertion openings that can open the side and / or rear area (s) widely. footwear to allow easy insertion and easy removal of a foot. Such shoe constructions can be particularly useful for "tall" athletic shoes, boots, or other shoes that have uppers that extend up to and / or at least partially over the wearer's ankles. More specific features and aspects of this invention will be described in more detail below.
[020] Some aspects of this invention relate to footwear articles which may include: (a) an upper part that has an opening through which a user's leg extends (for example, which includes a top opening, a first side edge that extends forward from the top opening and along a instep area, and a second side edge opposite the first side edge and that extends forward from the top opening and along o instep area), where the upper part additionally includes a foot insertion opening that extends back and down from a front portion of the leg opening (for example, from the first side edge) at least for an upper heel area; (b) a closing system for releasably closing the foot insertion opening (for example, optionally including a zipper element or other releasable closing system); and (c) a sole structure engaged at the top. The closure system may additionally include one or more of: (a) a strip that extends at least partially around the leg (for example, along the front of the leg, over the first side edge and over and beyond the second edge lateral, etc.) and releasably attaches to the upper and / or sole structure, (b) a shoelace element (or a non-stretch clamping element) that extends through the instep area one or more times and which connects the first and second lateral edges of the upper part, and / or (c) one or more stretch or elastic elements that extend through the instep area and which connect the first and second lateral edges of the upper part. This closure system may include structures to tighten the shoe fitting around and secure the shoe to the user's foot.
[021] Optionally, if desired, the strip (which optionally can be engaged with a slide element of the zipper system when the closing system includes a zipper system) can be engaged with the lace element in such a way that the pull of the strap, pull and tighten the lacing element on the instep area. In such structures, the pull on the strap to secure the shoe to a user's foot can work to close the closure system (for example, close the zipper system) and then squeeze the shoelace element through the chest area of the foot. Optionally, in such structures, the shoelace element will be substantially inelastic and non-stretchable, and that shoelace element can be engaged with one or more elastic elements (for example, elastic band (s) that allow the the strip is pulled at a desired tightening level). The strap, the elastic element (s) and the shoelace element can form a continuous path around the user's foot (for example, from the instep area to the top and around the leg or lower ankle).
[022] In other structures, however, the strap and the shoelace element and / or elastic elements across the instep area can be separated from each other in such a way that, during the pull on the strap to secure the shoe in a user's foot, can work to close the closing system (for example, closing the zipper system and / or tightening the strap around the foot), this action does not tighten or otherwise directly affects the shoelace element or other closing elements through the instep area. If desired, at least some portion (s) of the strap may be elastic or stretchable (s) to allow some tightening around the leg.
[023] Also, if desired, in some structures according to this invention, at least some portions of the closure system (for example, at least some portions of the shoelace element, at least some portions of the component (s) ) elastic (s) of the closure system, at least some portion of the strip, etc.) may extend between different layers of the upper part. Some portions of the closing system (and its clamping structures) can also be located inside the upper part and / or outside the upper part. If desired, a guide system can be provided with the upper part to form and maintain a path through which at least some portions of the closure system can pass. The guide system, which may consist of one or more individual parts or components, may form a tunnel or other passageway to contain portions of the closure system. The features of the guide system can also help to reduce or eliminate unwanted interactions between the locking / gripping elements and other items.
[024] As another potential resource, footwear articles according to at least some examples of this invention may include a grip element engaged at the top at a location adjacent to the foot opening of the shoe (for example, at or near the top opening through which the user's leg extends when the shoe is attached to the foot, at or near an edge of the leg opening, at or near the foot insertion opening and / or at or near the closure system for the foot insertion opening). This handle element can be held by the user as the user pulls the top portion of the top (above the foot insertion opening and the closing system) to open the closing system for removing the foot. The grip element may include tactile or grip enhancement features and / or may provide added durability or wear resistance for that area (in view of its repeated handling for removing shoes).
[025] Although the foot insertion opening in the shoe may extend any desired distance around the upper, in at least some examples of this invention, the foot insertion opening extends at least to a rear heel area of the foot. top, and in some cases to or beyond a vertical line extending upward from a point further behind the top.
[026] In view of the general description of resources, aspects, structures, processes and dispositions according to certain modalities of the invention provided above, a more detailed description of specific examples of footwear articles and methods according to this invention will be given below. II. Detailed Description of Examples of Footwear Articles According to this Invention
[027] With reference to the Figures and the following discussion, various footwear articles and resources thereof according to the present invention are described. The revealed and discussed footwear consists of athletic footwear, and the concepts revealed in relation to various aspects of this footwear can be applied to a wide range of athletic footwear styles, which include, but are not limited to: basketball shoes, football, walking shoes, casual shoes and the like. In addition, at least some concepts and aspects of the present invention can be applied to a wide range of non-athletic footwear, which includes professional boots, boots for clothing and the like. Accordingly, the present invention is not limited to the exact embodiments disclosed in the present invention, but applies to footwear in general.
[028] Figures 1A to 1E provide several views of an example of a shoe article 100 according to aspects of this invention. Figure 1A is a side view, Figure 1B is an intermediate side view, Figure 1C is a top view, Figure 1D is a rear view and Figure 1E is an approach view of a portion of the closure system or grip for that shoe item example 100. As generally shown in these Figures, shoe item 100 includes an upper 102 and a sole structure 104 engaged with the upper 102. The upper 102 of this illustrated example is an upper high-top athletic shoes (for example, for basketball), although other shoe styles and upper styles are possible. The upper part 102 of this example may include a piping member or other structure that extends along the bottom plantar support surface (to at least partially surround the bottom of the standing reception chamber). The upper top 102 defines a leg opening 106 for the shoe (through which the wearer's leg extends when shoe 100 is attached to the foot).
[029] Although it can adopt any desired configuration and / or structure without departing from the invention, the sole structure 104 of this illustrated shoe example 100 includes a polymeric foam midsole 104a (for example, produced from polyurethane foam, an ethyl vinyl acetate (EVA) foam, a light foam from the LUNAR family of products (available from NIKE, Inc., Beaverton, Oregon, USA, etc.). In addition or alternatively, if desired, midsole 104a may include one or more impact force attenuation columns (for example, made of foam), one or more mechanical impact force attenuation components (for example, structures of the type "shock absorber") and / or one or more fluid-filled bladder structures. This midsole 104a is engaged with one or more outsole components 104b that at least partially cover midsole 104a (for example, by gluing or otherwise fixed) and provide at least a portion of a ground contact surface (for example, example, with wear resistance properties, one or more traction elements, etc.). The midsole 104a and / or outsole 104b can form one or more independent parts and can extend over the entire length and / or width of the shoe article 100 or just portions thereof. Also, although shown on the outside in relation to the upper 102 in this illustrated example, some or all of the midsole 104a could be contained (or at least partially contained) in the inner chamber defined by the upper 102. If desired, the edging mentioned above it could be omitted (or at least partially omitted) and the midsole 104a could provide the plantar support surface (or at least a portion thereof) for the shoe article 100.
[030] As additionally shown in these Figures, the upper part 102 of this illustrated example includes the top leg opening 106. The general opening of this example shoe article 100 includes a first side edge 108a (for example, an intermediate side edge) extending forward from the top opening 106, down and along the instep area of the shoe 100. A second side edge 108b (for example, a side edge edge, opposite the first side edge 108a) also extends forward from the top opening 106, down and along the instep area of the shoe 100. The upper 102 may additionally include a tongue element 110 or another moderating component (for example, a member of the shoe). boot type) that sits along the front of the lower leg and ankle area and over the instep area of the shoe 100 (below the side edges 108a, 108b and between the side edges 108a, 108b and a user foot) .
[031] As additionally shown in Figures 1B and 1D to 2C, that top example 102 additionally includes a relatively large foot insertion opening 120 that extends back and down from the first side edge 108a at least to one upper heel area 102. A closure / gripping system 130 (which includes a zipper system 132) is provided to releasably close the foot insertion opening 120 and secure the footwear 100 in / on a user foot. These features of this shoe structure example 100 will be described in more detail below.
[032] The foot insertion opening 120 allows the top opening 106 and the upper 102 of the shoe 100 to be opened wider to allow easy insertion of a foot. As shown in Figures 1B and 2A, the front end 120a of the foot insertion opening 120 starts at the first side edge 108a in an upper leg / ankle coverage area 102. That front end 120a can start in other locations around along the general shoe opening, which includes from the top opening portion 106 (optionally along one side of a user's leg) or at other locations along the first edge 108a (for example, closest to the opening of top 106, additionally down and also to the instep area, etc.). Additionally or alternatively, the foot insertion opening 120 could start (and be located at) on the second side edge 108b, if desired.
[033] As noted above, the foot insertion opening 120 in this illustrated example extends downward and backward from the first side edge 108a. Opening 120 can extend at least to a rear heel area of the upper 102 (for example, then, the closed end 120b of opening 120 is located in the rear heel area). Like some more specific examples, the foot insertion opening 120 can extend at least to a vertical line VL that extends through a point further behind the top 102, or even beyond that vertical line VL (see end location closed 120b in Figure 1D). The closed end 120b of the opening 120 may extend to the opposite side of the upper 102 still further in the distance shown in Figure 1D to further open the upper 102 to receive a foot, still to the rear side area of the heel (for example, PLRH point in Figure 1D) or the lateral heel area (PLH point in Figure 1A), if desired.
[034] While the actual size of the foot insertion opening 120 may vary (for example, depending on the size of the shoe, etc.), in at least some examples of this invention, the foot receiving opening 120 will extend to a length (from points LOE to LCE along the zipper system 132) around at least 35% of a perimeter dimension of the top opening 106 around the heel (i.e., the dimension of the top leg opening 106 around the heel from the first side edge 108a (Pi) to the second side edge 108b (P2)). Points Pi and P2 are located where the top leg opening 106 meets the side edges 108a and 108b, respectively. If an empty corner point that transits between the top opening 106 and the side edges 108a and / or 108b is not provided on a specific shoe model at those locations, points Pi and P2 can be determined as the location of a tangent point horizontal where the top opening 106 and the side edges 108a, 108b meet (when the shoe 100 rests on a horizontal surface). In some more specific examples, the foot insertion opening 120 (for example, the longitudinal length of the zipper cord) will extend around at least 40%, at least 50% or at least 55% of that perimeter dimension. From a more absolute dimensional point of view, in at least some examples of this invention, the length of the foot insertion opening 120 (from LOE to LCE points along the zipper cord) can be at least 12.7 cm (5 inches), and in some instances, at least 15.24 cm (6 inches), or at least 17.78 cm (7 inches).
[035] From a vertical point of view, the closed end 120b of the foot insertion opening 120 can be located in less than 35% of an overall height dimension of the upper 102 at the location of the closed end 120b. More specifically, as shown in Figure 1 D, the vertical dimension (with the shoe 100 resting on a horizontal support surface S) from the closed end 120b to the place where the upper 102 and the sole 104 meet (at midsole top surface 104a in this example), HCE, is 35% or less than an overall vertical height H of the upper part 102 at that location. In some more specific examples, the closed end 120b of the foot insertion opening 120 can be located at a height of 30% or less, 25% or less, or 20% or less of that overall height dimension H.
[036] From a more absolute dimensional point of view, in at least some examples of this invention, the closed end 120b (point LCE) can be located less than 1.212.7 cm (5 inches) vertically from the point of junction of the upper / sole at that location, and in some instances, less than 2.54 cm (1 inch) or even less than 0.712.7 cm (5 inches) from that junction point. In relation to the actual height from a horizontal contact surface S, the closed end 120b (point LCE) can be located less than 2.12.7 cm (5 inches) vertically from the contact surface S, and in some examples, less than 2.212.7 cm (5 inches), less than 5.08 cm (2 inches), or even less than 1.712.7 cm (5 inches) from that contact surface S. Additionally, in relation to actual height from a horizontal contact surface S, the open end 120a (LOE point) can be located at least 3.12.7 cm (5 inches) vertically from the contact surface S, and in some instances at least least 3.712.7 cm (5 inches), at least 10.16 cm (4 inches) or at least 4.212.7 cm (5 inches) from the contact surface S. The vertical spacing distance between the closed end 120b ( point LCE) and open end 120a (point LOE) (HDIFF in Figure 1E) can vary without departing from this invention. In some more specific examples, the vertical height differential between the LCE and LOE (HDIFF) points can be at least 1.12.7 cm (5 inches), and in some examples, at least 1.712.7 cm (5 inches) at least 5.08 cm (2 inches), and at least 2.212.7 cm (5 inches).
[037] Various aspects and exemplary features of shoe closure / gripping systems (e.g. system 130) for footwear articles according to at least some examples of this invention will now be described in more detail. As shown in Figures 1A to 3A, this example of a shoe article 100 includes a zipper system 132 engaged at the top 102 at opposite side edges of the foot insertion opening 120 to at least partially close the foot insertion opening 120. In this construction example, the zipper system 132 completely closes the foot insertion opening 120 (i.e., extends from LOE Points to LCE). Thus, the zipper system 132 can be at least 35% of the perimeter dimension of the top opening 106 around the heel discussed above (and in some examples, that length will be at least 40%, at least 50% or at least 55% of that perimeter dimension). From a more absolute dimensional point of view, in at least some examples of this invention, the length of the zipper system 132 (from LOE Points to LCE along the zipper cord) can be at least 12.7 cm (5 inches) ), and in some instances, at least 15.24 cm (6 inches), or at least 17.78 cm (7 inches). Releasable locking systems in addition to zippers could be used, if desired, in some constructions according to some aspects of this invention.
[038] The slide element 134 of the zipper system 132 in this illustrated example is engaged in (or integrally formed to include) a strip 136. The strip 136 in this illustrated example extends from the middle side of the top 102, over the first side edge 108a, in addition to the second side edge 108b, and releasably attaches to the side of the upper part 102 (for example, through a hook and loop closure system 146, through a buckle assembly, through other mechanical connectors, etc.). Strap 136 and its gripping features help to keep zipper system 132 closed (for example, keeping slide element 134 at or near the LOE point) and help to secure shoe 100 to the user's foot in a fair and comfortable.
[039] The closing / gripping system 130 of this shoe structure example 100 additionally includes a shoelace element 138 that extends through the instep area of the shoe 100 and connects the first side edge 108a and the second side edge 108b of the upper part 102. If desired, this shoelace element 138 can engage the upper part 102 through eyelets or eyelet-type openings formed in the upper part 102 (for example, closer side edges 108a, 108b) in a conventional manner as is commonly known and used in the footwear technique. In addition or alternatively, the shoelace element 138 can also be tied to the front / top of the upper 102 (for example, in the instep and / or front leg area) in ways that are known and used in the shoe technique. The shoelace element 138, at least in part, may constitute a non-stretch cord, textile product, plastic, fiber, metal or other component. The terms "non-stretchable" or "non-stretchable" as used in the present invention in this context mean a material that stretches less than 10 of its length (that is, less than 0.5.0 cm (2 inches) to a length of 5.08 cm (2 inches) of the material), when a tensile force of 10 pounds is applied to a length of 5.08 cm (2 inches) of the material.
[040] In this illustrated structure 100, the shoelace element 138 engages with strip members 138a that can extend at least partially around the user's foot and / or at least partially below a plantar support surface of the shoe. If desired, at least some of the strip members 138a can extend completely around the plantar support surface of the shoe 100, from edge 108a to edge 108b. Shoelace engagement structures and strap members 138a of this type are described in Patent Application Publications No. US 2012/0011744 and US 2012/0198720, applications of which are fully incorporated into the present invention by reference. Any of the enveloping hitch systems and / or the lace hitch structures described in these patent publications can be used in conjunction with shoe structure 100 according to this invention. These types of enveloping hitch systems and / or shoelace hitch structures can help provide a very comfortable, adaptive and secure fit of a footwear to a user's foot.
[041] The closing / grasping system 130 of this shoe structure example 100 includes additional features. As shown in Figures 1B and 1E, strip 136 is engaged with two stretch or elastic members 140a and 140b (although one or more elastic members can be used without departing from this invention). The elastic members 140a and 140b help to ensure that the strip 136 is pulled firmly to engage the strip 136 around the user's foot, for example, as shown in Figure 1E. Although not a requirement, as shown in the illustrated example, the elastic member portions 140a and 140b extend between the upper layers (for example, as shown in Figure 1B). The elastic members 140a and / or 140b can extend through the guide system 160 (also called "guide element" or "guide member" in the present invention), as will be explained in more detail in conjunction with Figures 4A to 4D (and the potential locations and strands of the guide system 160 are shown in dotted and double dash lines in Figures 1A, 1B and 1D). The term "stretchable" as used in the present invention in this context means a material that stretches at least 25% of its length (that is, at least 0.12.7 cm (5 inches) to a length of 5.08 cm (2 inches) of material) when a tensile force of 10 pounds is applied to a length of 5.08 cm (2 inches) of the material. An "elastic" material is a "stretch" material that returns at least substantially (that is, at least 95%) to its original length when the 10 pound force is released. Additionally or alternatively, if desired, at least a portion of strip 136 may be stretchable (in place of or in addition to any stretch provided by elastic members 140a, 140b).
[042] If desired, the elastic member (s) (eg 140a, 140b) or another strip 136 that tightens or holds the structures can be fixedly attached to the shoe 100 (for example, in the upper 102, in the sole structure 104, between the upper 102 and the sole structure 104, etc.) to provide a support for pulling the strip 136 and stretching the member (s) ) elastic (s) 140a, 140b and / or strip 136. Such a system can be used, for example, if the lace element 138 is of a conventional design (for example, tied separately by the user) or if the lace element 138 is replaced by another type of instep closure system, such as one or more elastic bands (as described in greater detail below in conjunction with Figure 5) or other elements. The shoe structure example 100 of Figures 1A to 1E, however, has a different construction. As shown in Figure 1C, in this example of structure 100, the two opposite ends of the shoelace element 138 extend between the top 102 layers at a location along the second side edge 108b of the top 102. Thus, in this example of structure, shoelace 138 engages more eyelets or other shoelace engagement elements 138a on the first side 108a than on the second side 108b, and the free ends of the shoelace element 138 join and extend along the upper 102 in the second side 108b. If desired, the shoelace element 138 may extend through a guide system 160, as will be explained in greater detail in conjunction with Figures 4A to 4D. These shoelace ends 138 can engage (directly or indirectly) with the free ends of elastic members 140a and 140b (for example, at a location within or between the upper layers 102) such that the pulling of strip 136 to to stretch the elastic members 140a and 140b apply a pulling force to pull and tighten the lace element 138 in and through the instep area.
[043] Therefore, the closure / gripping system 130 according to this illustrated example of shoe structure 100 includes: (a) a first portion (for example, shoelace element 138) extending between the first side edge 108a and the second side edge 108b in the instep area (that shoelace element 138 can tighten a strap system that wraps around the sides and at least for a foot support area of the shoe), (b) a second portion ( for example, at least a portion of shoelace element 138 and / or at least a portion of elastic members 140a, 140b) extending beyond the second side edge 108b (and optionally within or between the upper layers 102) and in around the upper heel area 102, and (c) a third portion (e.g. strip 136) extending beyond the first side edge 108a and over the second side edge 108b to releasably engage the top 102 ( for example, through a provision of hook and loop closure). The first, second and third portions of the closure / gripping system 130 can form a continuous path (for example, from the front, the instep area of the shoe 100 to the free end of the strip 136). At least some part of the first and / or second portions of the closure / gripping system 130 may be non-stretchable, while at least some part of at least one of the second and / or third portions of the closing / gripping system 130 may be be elastic or stretchable. If desired, at least some part of the first and / or second portions of the locking / gripping system 130 (for example, at least some part of lace element 138 and / or elastic members 140a, 140b) may extend into the inside the upper part 102 and / or between the upper part layers 102. In addition or alternatively, if desired, at least some part of the third portion of the closure / gripping system 130 (for example, strip 136) may extend to the interior of the top 102 and / or between the layers of the top 102.
[044] The operation of the closing / grasping system 130 will be described in greater detail below in conjunction with Figures 2A to 3A. Figures 1A to 1E illustrate the shoe article 100 with the closing / grasping system 130 engaged and pulled firmly, for example, as it would be when attached to a user's foot (not shown). In this arrangement, the elastic members 140a, 140b (or other elastic portions) can be pulled firmly and held in place by a release mechanism between strip 136 and upper 102 (or sole frame 104), for example, through a hook and loop closure system 146, through a buckle assembly, through another type of releasable connection, etc.). This configuration can also pull the slide 134 of the zipper system 132 to the open end 120a of the foot insertion opening 120, thereby closing the foot insertion opening 120.
[045] To remove the footwear 100 from the foot, first, the strip 136 is released from its release connection of the upper 102 and / or sole structure 104 (for example, by disconnecting the hook and loop fastener components 146 ). This action causes the elastic members 140a, 140b to return to their unstretched condition. The elastic portions of the closing / grasping system 130 (for example, elements 140a, 140b and / or elastic on strip 136) can be dimensioned so that when the pulling force is released in this way, the retraction of the elastic components will cause that the slide element 134 of the zipper system 132 begins to move under the zipper cord 132 (at least if the slide element 134 has been extended to the end 120a of the zipper cord). As an example, this release of tractive force can move the slide element 134 by at least a few teeth down the zipper cord (for example, 1 to 10 teeth), as shown in Figure 2A. This release of tractive force can also, at least in part, loosen the shoelace element 138 through the instep area of the shoe 100 (for example, if strap 136 and elastic members 140a, 140b are operationally coupled to the element of lace 138).
[046] If desired, it would be possible to continue opening the zipper system 132 by pulling the strip 136 to move the slide 134 further down the zipper cord (optionally to the closed end 120b). Alternatively, the user can take the top 102 at a location above and / or behind the foot insertion opening 120 and pull the top portion of the top 102 back to move the slide element 134 under the zipper cord. (and to essentially remove the upper 102 around the user’s leg). See Figure 2B. As shown in Figure 2C, this action moves the slide element 134 back and down towards and / or to the closed end 120b of the foot insertion opening 120 and opens up a large wide area for removal and insertion of one foot. Optionally, if desired, the upper part 102 may include an abrasion / wear resistance and / or handle accentuation element 144 in a place where the user will tend to pick up the upper part 102 during this release system phase. closure / grip 130. In addition or as an alternative to a layer of abrasion / wear resistance and / or handle accentuation, element 144 may also include a projecting flap (for example, fabric or plastic) or a manipulation element that extends outwards from the top (capable of being picked up).
[047] To wear shoes 100, shoes 100 can start with the closure / grip system 130 in the arrangement shown in Figure 2C, and the user can insert his foot in shoes 100 through the open closure / grip system 130. Case if desired, the tongue element 110 can be attached to the upper 102, for example along one or both side edges 108a, 108b, to help prevent the tongue element 110 from falling into the shoe 100 (and , so be on the way when the user inserts their foot). This can be accomplished, for example, with the use of sewing or embroidery (to tack the tongue element 110 to one or both edges 108a, 108b), using one or more strips of the elastic type 110a (so that the tongue 110 is attached to the edge (s), but can still be stretched forward in relation to the opening area), or in other ways. Like other potential options, the tongue element 110 can be integrally joined along the side edges 108a, 108b and / or optionally produced from at least partly from an extensible or stretchable material, such as from an elastomeric / stretch fabric of the SPANDEX type (for example, as an inner boot element), with a reinforced construction along at least one of the side edges 108a, 108b, etc.
[048] Once shoe 100 is positioned on the foot, strip 136 can be pulled out and up as shown in Figure 3A, the action of which moves slide 134 of the zipper system 132 onto the zipper cord in towards the open end 120a of the foot insertion opening 120 to thereby approach the foot insertion opening 120. In this way, strip 136 can be pulled firmly and wrapped around the front of the ankle / leg, over the first and second side edges 108a, 108b and attached to the opposite side of the upper part 102 from the main part of the zipper element 132 (for example, using the hook and loop fastener 146). This strap tightening action 136 can also, at least in part, tighten the shoelace element 138 through the instep area of the shoe 100 (if the strap 136 and the elastic members 140a, 140b are operatively coupled to the shoe element) lace 138).
[049] Although the modality shown in Figures 1A through 3A shows the shoe 100 with the zipper element 132 first on the middle side of the upper 102 (and the strip 136 wrapping from the middle side to the side), the opposite configuration also it is possible (with the zipper element 132 first on the side of the upper part 102 and the strip 136 wrapping from the side to the middle side). As another potential option, if desired, a shoe 100 of a pair of shoes can have the zipper element 132 first on the middle side of the top 102 (and the strip 136 wrapping from the middle side to the side) and the other footwear of the pair may have the opposite configuration (with the zipper element 132 first on the side of the top 102 and the strip 136 wrapping from the side to the middle side).
[050] Optionally, if desired, and as shown in Figure 3B, the rear heel area of sole 104 and / or the upper 102 can include a handle or flap 150 that the user can hold to help pull the shoe 100 on your foot (and put your fingers under the end of the shoe 100). Other structures can be provided for this purpose, if desired. For example, the handle or flap 150 can be shaped and positioned (for example, of sufficient length to contact the sole) so that the user can make a downward movement (or, otherwise, apply force to it) to maintain the shoes 100 in place while the toes that are inserted are pushed into the upper 102. As another example, as shown in Figures 3B and 3C, the upper 102 or sole frame 104 may include a rolling element 152 along on one side that extends laterally to allow a backward force to be applied to the shoe 100 (for example, by the opposite foot or leg; by a wall, table or chair; etc.). Optionally, this type of rolling member 152 can be mounted to fold forward along the side of the upper 102 and / or sole frame 104, for example, on a hinge 154 or to retract on the sole frame 104 (or between the upper part 102 and the sole structure 104), for example, by means of a spring loaded assembly.
[051] As mentioned above, if desired, at least some portions of the lace element 138 and / or the elastic members 140a, 140b may extend within or between the upper layers 102. As another option, if necessary desired, these members may at least partially extend around the heel area of the shoe 100 around the outer surface of the upper 102. In such structures, at least some portions of the shoelace element 138, the elastic members 140a, 140b and even strip 136 can extend through a guide system 160. Guide system 160 can help to hold shoelace 138, elastic members 140a, 140b, and / or strip 136 in the desired position (s) (s) in relation to the upper 102 and / or help to maintain a clean trajectory so that these components can be pulled firmly when shoe 100 is attached to a user foot. The guide system 160 can also help hide these components to prevent unwanted or unnecessary contact and / or interaction with other objects.
[052] Figures 4A to 4D show the cross-sectional views of the various potential examples of the structures of the guide element 160. The guide element (s) 160 can be supplied along at least fewer portions between the desired strands of the lace element 138, the elastic members 140a, 140b and / or the strip 136, as shown in the double dotted lines in Figures 1 A, 1B and 1D.
[053] Figure 4A shows a guide member 160 provided as a tubular member between the two layers 102a and 102b of the top material (for example, between an inner layer of spacer mesh and an abrasion resistant TPU or outer layer synthetic leather). Guide member 160 can be produced from a flexible or rigid material, for example, plastic, fabric or textile materials. The guide member 160 can additionally include frames 162 which allows the guide member 160 to be engaged with one or both of the top layers 102a, 102b, for example, such as by sewing or embroidering, by adhesive or glues, by means of fusion techniques, etc. An internal area 164 defined by the guide member 160 houses at least the portions of the lace element 138 and / or elastic members 140a, 140b (and / or optionally, at least a portion of the strip 136), depending on the location of the guide member 160 around the footwear 100.
[054] Figure 4B shows a similar construction with a two-layer upper part in which the guide member 160 'has an open side and a surface of one of the upper layer layers (for example, layer 102b, in this example) defines a side of the guide member internal area 164 '(in which elements 138, 140a, and / or 140b are contained). Again, the guide member 160 'can be engaged in one or both of the top layers 102a, 102b, for example, in structures 162', such as sewing or embroidery, by adhesives or glues, by means of fusion techniques, etc.
[055] Figure 4C shows a guide member 160 "engaged in a single layer 102a of an upper part. Again, guide member 160" has an open side and a surface of the upper layer 102a defines one side of the area. inner guide member 164 "(in which elements 138, 140a, and / or 140b are contained). Again, guide member 160" can be engaged with the top layer 102a, for example, in structures 162 ", such as by sewing or embroidery, by adhesive or glues, by means of fusion techniques, etc. In this exemplificative construction, the guide member 160 "extends out of the top layer 102a and the guide member 160" can be oriented on an inner surface or an outer surface of that top layer 102a.
[056] Figure 4D also shows a guide member 160 "'engaged in a single layer 102a of an upper part. In this exemplary structure, a thin covering element166 is provided along at least some portion of a longitudinal length of the member guide 160 '"(to close and partially define the internal area 164'" in which the elements 138, 140a, and / or 140b are contained). This cover element 166 can be formed from any desired type of material, which includes, for example, a flexible or rigid polymeric material, a fabric or textile material, etc. Again, the guide member 160 '"can be engaged with the top layer 102a, for example, with structures 162"', such such as by sewing or embroidery, by adhesive or glues, by means of fusion techniques, etc. In this exemplary construction, the guide member 160 "'extends or is lowered in the upper layer 102a and the guide member 160"' can be oriented on an internal surface the u an outer surface of that top layer 102a. In some structures, if desired, the cover member 166 may be omitted, at least over some portions of the guide member structure 160 "’.
[057] While always showing that it includes two elements 138, 140a, and / or 140b in Figures 4A to 4D, the guide elements of any of these types can include a single portion of the closing / grasping system 130 or more than two components . For example, as shown in Figures 1 A, 1B and 1D, the guide member can split or split in the rear heel portion (or other portion) of the shoe structure 100 and a single element 138, 140a, and / 140b can be provided on at least some of the guide members (for example, on opposite sides of the zipper system 132). The guide system does not need to extend continuously along the total trajectory shown in Figures 1A, 1B and 1 D, but it can be discontinuous (for example, in multiple separate parts, for example, similar to loop-type structures belt) or, otherwise, less than the total path.
[058] If necessary or desired, in any of the constructions of Figures 4A to 4D, the inner wall of the inner area 164, the elements 138, 140a and / or 140b, the covering element 166 and / or the surface of the upper part 102 defining the inner area 164 can be treated to reduce the sliding friction between the various parts contained in the inner area (for example, so that elements 138, 140a and / or 140b move more freely and easily pulled or released). As some more specific examples, if desired, treatment may include an infusion or coating of polytetrafluoroethylene, infusion or coating of graphite, treatment with other lubricants, etc. In addition or alternatively, if desired, at least the inner wall portions of the inner area 164 of the guide element 160, the cover member 166 and / or the upper surface 102 can be produced from a material that has a low coefficient of friction in relation to elements 138, 140a and / or 140b. The elements (eg 138, 140a, 140b) contained within the inner area 164 can be produced from materials or treated to have a low coefficient of friction in relation to one another (or in relation to other surfaces and / or structures inside the internal area 164). These features can help prevent elements 138, 140a and / or 140b from bonding and / or sticking when the lock / grip system 130 is tightened or released.
[059] In the shoe structure 100 in which the instep grip element (s) (for example, non-elastic or non-stretchable shoelace elements 138) engage directly with the strap to pull 136 (for example, through components of elastic extension 140a, 140b), the location of the transition between the non-stretchable shoelace elements 138 and the elastic strap components for pulling 140a, 140b can occur at any desired location around the upper structure 102. As some more specific examples, this transition can occur in the lateral heel area (for example, see Figure 1A, point P 4), in the rear heel area (for example, Figure 1 D, points P 5) or even in the area mid-heel (for example, Figure 1B, points P 6). This transition can also occur within the guide elements 160 (if any), between layers of the top 102 (if multiple layers are present), inside the top 102 and / or outside the top 102. When two or more gripping component trajectories (138, 140a, 140b) are provided around the top 102, the transition (s) between the elastic and non-stretchable materials (if any) can occur in the same or in different locations around from the top 102.
[060] Figure 5 illustrates another exemplary shoe structure article 500 according to some examples of this invention. While the shoe structure 500 of Figure 5 is similar to that of Figures 1A through 1 D, in this example the structure 500 is illustrated, the lace elements 138 of Figure 1C are replaced by one or more elastic or stretch bands 502 that extend transversely to the instep opening from side edge 108a to side edge 108b. The elastic band (s) 502 allow the size of the instep area of the shoe 500 to expand as the foot moves inward and then resumes to or towards its original size to help keep the shoe in a tight condition on the user's foot. If desired, elastic bands 502 can engage straps 138a in adaptive or wrap-around type components of the types described above in conjunction with Figure 1C (and as described in Patent Application Publication— US 2012/0011744 and 2012/0198720 ).
[061] In this exemplary structure 500, strip 136 continues to engage with a slide element 134 of the zipper system 132 and is mounted on one or more elastic elements 140a, 140b that extend at least partially around the user's foot to assist to attach the shoes to the user's foot. The elastic element (s) 140a, 140b, in this example illustrated shoe structure 500, however, do not extend around and / or engage the closure / grip element (s) 502 provided (s) in the instep area of the shoe. Preferably, in this shoe structure 500, the elastic element (s) 140a, 140b are attached to one of the upper 102 and / or the sole structure 104 and / or kept between the upper 102 and the sole structure 104. The attachment point for the end (s) of elastic member (s) 140a, 140b can be at any desired location around the shoe structure 500, such as in the lateral heel, in the rear heel area and / or in the medial heel area, etc. (for example, in the general areas projected as points P4, Ps and Pe in the above speech in relation to Figures 1A through 1E, between the upper and the sole structure, etc.). In addition or alternatively, if desired, strip 136 could be produced from at least partially a stretch material and used to fasten footwear 500 to the user's leg.
[062] The shoes 500 of Figure 5 can include strip 136, zipper system 132, and / or elastic elements 140a, 140b of the types described above in Figures 1A through 1D and these components can operate in the same way as or similar to that described above for structure 100 of Figures 1A to 1D (for example, as described in conjunction with Figures 2A to 3A) except loosening of strip 136 and relaxation of the pulling force on elements 140a, 140b will not affect the tightening through of the instep area. Despite this, the zipper system 132 and the closure system 130 can be opened and closed in the same general way.
[063] That person skilled in the art will understand that the structures, options and / or alternatives for the shoe structure described in the present invention, which includes the features of several different modalities of the invention, can be used in any combinations, subcombination and the like, without departing from the invention. For example, if desired, the elastic band (s) 502 of Figure 5 can be used in conjunction with the lace element 138 of Figures 1A through 3A. As another example, the shoe structure 500 of Figure 5 can include the handle and / or bearing member of Figures 3B and 3C without departing from this invention. The exemplary shoe structure 500 of Figure 5 can also include one or more of the guide element structures 160 and arrangements as shown in Figures 4A to 4D, if desired. Other combinations of specific features, components and combinations can also be used without departing from this invention.
[064] Additionally, variations of the illustrated structures can be produced in the closure / gripping system 130. As some of the additional examples, if desired, more or less (or none) elastic bands 140a, 140b can be provided without departing from this invention. Additionally or alternatively, elastic bands 140a, 140b, when present, may have different sizes, cross-sectional shapes, location (s) for affixing to strip 136 and similar to the structures specifically illustrated and bands 140a, 140b in a single shoe 100 (when multiple lanes are present) can have the same or different constructions. The strip (s) 140a, 140b may also extend around the shoe 100 in different directions from those illustrated, which includes at different angles and / or directions relative to each other. The strip (s) 140a, 140b need not extend inside and / or between layers of the upper part 102 as shown in Figure 1B, but if they extend, the location (s) in which the strip (s) 140a, 140b moves from an external location to an internal location in relation to the top 102 may vary (for example, the location (s) may be close to strip 136, in lower and / or higher locations in relation to the zipper system 132, additionally around the rear heel area, more to the opposite side of the shoe, in places with wider separation around the perimeter, etc.). Also, the total location for the strip (s) 140a, 140b (i.e., the opening through which the strip (s) 140a, 140b extends within the top 102) may have different shapes than rounded shapes, such as square, rectangle, triangle, other polygonal shapes, oval or elliptical, star-shaped, cross-shaped, logo-shaped, irregularly shaped, etc. More than a strip 140a, 140b can extend through a single opening into the top 102, if desired (for example, in a location beyond the end of the zipper system 132). When multiple openings for this purpose are present in a shoe construction, individual openings can have the same or different shapes from each other. Strip 136 can also be dimensioned, shaped and oriented differently from the illustrated structures and arrangements, if desired. The various options noted above can also be used in any desired combinations or sub-combinations without departing from this invention. Accordingly, a wide variety of design options and choices are available for the various structures of the closure / grip system 130.
[065] The shoelace component 138 and its orientation in a shoe can also differ without departing from this invention. For example, as noted above, shoelace component 138 may engage more conventional eyelets or holes through the upper 102 in the instep area. The shoelace component 138 can also have different sizes, cross-sectional shapes, and / or traverse the instep area of the shoe 100 a number of times different from that shown without departing from this invention. Also, while the shoe 100 of Figure 1C shows both ends of the shoelace component 138 which extends inside the upper 102 on the side of the shoe 100, other arrangements are possible without departing from this invention. For example, both ends of the shoelace component 138 could extend inside the upper 102 on the middle side of the shoe 100. As another example, the opposite ends of the shoelace component 138 could extend inside the upper 102 in the opposite sides of the shoe 100 (and potentially engaging different strips 136 or one between the ends of the shoelace component 138 could wrap around a direction changing element provided on or with the shoe 100 to change the direction and engage the strip 136 as the other end). As yet another example, if desired, the ends of the shoelace component 138 could extend along the outside of the upper 102 (on one or both sides, optionally at least partially within a guide member 160). Accordingly, many variations in the shoelace structure 138 and arrangement are possible without departing from this invention.
[066] Tension application systems (for example, for tightening the lace element 138 and / or strip 136) can also have other structures without departing from this invention. For example, a pulley doubling system can be provided, for example, to reduce the pulling force required to apply the pulling force to the shoelace element 138. As additional options, other tensioning devices could be provided, for example, in the front, instep and / or lateral ankle areas of the shoe 100, such as a "retract" swivel mechanism that coils excess shoelace element 138 (and thereby applies tractive force to the lace element 138). Such tensioning devices can replace strip 136 and elastic bands 140a, 140b on at least some shoe structures and / or can be engaged with zipper slide 134, if desired, to pull down zipper slide 134 and back when the tension is released (for example, to perform tension release functions in relation to the zipper slide 134 described above in conjunction with Figure 2A). III. Conclusion
[067] The present invention is disclosed above and in the accompanying drawings with reference to a variety of modalities. The purpose of the disclosure, however, is to provide an example of the various features and concepts related to the invention, not to limit the scope of the invention. An individual skilled in the relevant art will recognize that numerous variations and modifications can be made to the modalities described above without departing from the scope of the present invention, as defined by the appended claims.
