ARTICLE OF FOOTWEAR WITH HINGED UPPER FOR USE BY PERSON WITH CONSTRAINED PHYSICAL MOVEMENT
An article of footwear that offers an easy opening upper to allow the footwear to be easily placed on or off a wearer's foot is disclosed. The upper includes a flap that is positionable between open and closed positions. The entire foot receiving portion of the footwear is exposed with the flap portion in the open position. The wearer placed his or her foot within the foot receiving portion, without obstruction, and then moves the flap portion in the closed position, preferably with a slide fastener, thereby securing the wearer's foot within the article of footwear.
This application claims the benefit of U.S. Provisional Application No. 62/164,515, entitled “Article of Footwear with Hinged Upper,” filed May 20, 2015, which is incorporated by reference herein in its entirety for all purposes.
BACKGROUNDArticles of footwear generally include two primary elements, an upper and a sole structure. The upper is typically formed from one or more of a variety of material elements (e.g., textiles, foam, leather, or synthetic leather) that are stitched or adhesively bonded together to form a void on the interior of the footwear for a comfortable and secure fit. An ankle opening through the material elements provides access to the void, thereby facilitating entry and removal of the foot from the void. Alternatively, the upper can include a forefoot strap that is held in place with a toe stay or can include one or more straps that encircle the wearer's foot; footwear having these structures are collectively referred to herein as sandals.
The sole structure is located adjacent to a lower portion of the upper and is generally positioned between the foot and the ground. In some articles of footwear, the sole structure generally incorporates an insole, a midsole, and an outsole. The insole, which may be located within the void and adjacent to a lower surface of the void, is a thin compressible member that enhances footwear user's comfort. The midsole, which may be secured to a lower surface of the upper extending downwards from the upper, forms a middle layer of the sole structure. In addition to attenuating ground reaction forces (i.e., providing cushioning for the foot), the midsole may limit foot motions and/or impart added stability to the footwear. The outsole, which may be secured to a lower surface of the midsole, forms the ground-contacting portion of the footwear and is usually fashioned from a durable and wear-resistant material hat includes texturing to improve traction.
Generally, the midsole is the primary source of cushioning for the article of footwear, extending through the length and width of the footwear. It is typically formed from a foamed polymer material, such as polyurethane or ethyl-vinyl-acetate. Midsoles tend to be designed to optimize support and cushioning comfort for a wearer when walking or running. The forces acting on the midsole during these activities tend to be directed vertically and in a forward and aft direction relative to the article of footwear. Midsoles are designed to return predictable and consistent cushioning comfort and support when encountering such forces. Exemplar midsoles and uppers are shown in U.S. Patent Application Publication No. US2005/0267775A1, the entire disclosure of which is hereby incorporated by reference.
SUMMARYDespite the benefits of known articles of footwear, there remains a need for an article of footwear that is stylish and can easily be put on and taken off, particularly by physically challenged or physically constrained individuals.

In one embodiment, the invention is directed to an article of footwear having features intended to facilitate use by an individual with physical constraints; such an article of footwear may include an upper and a sole structure secured to the upper. The upper may include a rigid wall that substantially encircles an outer edge of the sole structure to define an unobstructed foot receiving portion therein, and a flap portion positionable over a forefoot portion of the article of footwear, which is pivotally secured to the rigid wall of the upper at a first edge and detachably securable to the rigid wall of the upper along a portion of the remaining edge, thereby defining an open position when the flap portion is pivoted out of the way to reveal a sufficient portion of the foot receiving portion to enable a user to directly place their foot into the article of footwear without encountering an obstruction requiring a sliding or similar motion, and a closed positon wherein the flap portion extends over the foot receiving portion.
In a further embodiment, the invention is directed to an article of footwear including an upper and a sole structure secured to the upper. The upper may include a lower upper including a rigid rim substantially encircling an outer edge of the sole structure and extending upwardly from the outer edge of the sole structure to a topline of the upper thereby defining an unobstructed and firm chamber therein surrounded by the rim for receiving a foot of a wearer. The lower upper may include four sides, such as a medial side, lateral side, forefoot side, and heel side, and a topline. The upper may further include a flap roofing the chamber having medial side, lateral side, and forefoot side and the flap on the medial side is pivotally secured to the topline of the upper on the medial side, and the lateral side and forefoot side of the flap being detachably secured on the topline of the upper on the lateral side and forefoot side, thereby defining an opening position by flipping up the flap on the lateral side toward the medial side and closing position by returning the flap on the lateral side toward the lateral side.
In a still further embodiment, the invention is directed to a shoe including an upper and a sole structure secured to the upper. The upper may include a lower upper including a rigid rim substantially encircling an outer edge of the sole structure and extending upwardly from the outer edge of the sole structure thereby defining an unobstructed and firm chamber for receiving a foot of a wearer and a flap attached to the lower upper by a securing means that enables the flap pivotally open and close by opening and closing the securing means,

General Footwear Structure
An article of footwear 10 is depicted in
Upper 20 is depicted as having a substantially conventional configuration incorporating a variety of material elements (e.g., one or more of textile, foam, leather, or synthetic leather) that are stitched or adhesively bonded together to the sole structure 30 to form an interior void for securely and comfortably receiving a foot. The material elements may be selected and located with respect to upper 20 in order to selectively impart one or more properties of durability, air-permeability, wear-resistance, flexibility, and comfort, for example. An ankle opening 21 in heel region 13 provides access to the interior void of the footwear.
Sole structure 30 is secured to upper 20 and has a configuration that extends between upper 20 and the ground. In effect, therefore, sole structure 30 is located so as to extend between the foot and the ground. In addition to attenuating ground reaction forces (i.e., providing cushioning for the foot), sole structure 30 may provide traction, impart stability, and limit various foot motions, such as pronation.
The primary elements of sole structure 30 are a midsole 31 and an outsole 32, as shown in
