Shoe

Patent No. US11172733 (titled "Shoe") was filed by Baker Scott Bradley on Nov 15, 2018.

What is this patent about?

’733 is related to the field of footwear, specifically shoes designed for ease of use, particularly for individuals with disabilities or limited mobility. Conventional shoes often require significant dexterity and flexibility to put on, posing a challenge for those with conditions like paralysis or muscular weakness in their feet. This can lead to discomfort, circulatory problems, and potential injury due to toes being cramped or bent during the insertion process.

The underlying idea behind ’733 is to provide a shoe with a large, easily accessible opening that allows the foot to be inserted without requiring the toes to be flexed or manipulated. This is achieved by incorporating a zipper fastener that runs along the side and front of the shoe, allowing a significant portion of the upper to be folded back, exposing the sole and creating an unobstructed pathway for the foot to slide in. The design facilitates a more natural and comfortable foot placement, minimizing the risk of injury or discomfort.

The claims of ’733 focus on a shoe comprising a sole, a top member defining a space for receiving a foot, and a single continuous zipper fastener . This fastener extends from a starting point on the lateral side of the ankle opening, traverses down towards the connection area between the top member and the sole at the front of the shoe, and then continues along the medial side towards a termination point. The zipper's configuration allows a portion of the top member to fold back, providing easy access to the foot-receiving space.

In practice, the user opens the zipper, which causes a large flap of the shoe's upper to swing open. The foot is then placed on the sole, heel first, and slid into the shoe. Once the foot is properly positioned, the zipper is closed, securing the foot within the shoe. The zipper's path is carefully designed to allow for a smooth, continuous motion when opening and closing, and to create a wide opening that accommodates various foot sizes and shapes.

Unlike traditional shoes that require the foot to be forced through a relatively small opening, potentially causing the toes to curl or bend, ’733 allows the foot to be placed directly onto the sole in a natural, extended position. This is particularly beneficial for individuals with limited mobility or sensation in their feet, as it reduces the risk of injury and promotes better circulation. The design also allows for variations in shoe style, from sneakers to boots, while maintaining the core functionality of the easy-access opening .

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2010s when ’733 was filed, shoes were typically manufactured with an opening positioned such that the foot must be inserted into the chamber or housing area for the foot through the opening toe first, followed by the remainder of the foot. At a time when systems commonly relied on laces, velcro straps, or elasticized portions around the opening to adjust the size of the opening, hardware or software constraints made it non-trivial to design a shoe that could be easily put on and removed, especially for individuals with disabilities or limited mobility.

Novelty and Inventive Step

The examiner approved the application because the amended claims included limitations not found in prior art. Specifically, the claims recite a shoe with a sole, a top member, an ankle opening, a lower connective edge, a fold-back portion, a fixed portion, a connection area, and a single continuous zipper fastener with a specific configuration. The examiner stated that the prior art of record would not be combinable to result in the claimed invention without substantial rearrangement and/or hindsight reasoning.

Claims

This patent includes 17 claims, with independent claims numbered 1, 7, 8, 11, 14, 15, and 16. The independent claims generally focus on a shoe design incorporating a sole, a top member defining a foot-receiving space, and a continuous zipper fastener to open and close the shoe. The dependent claims elaborate on specific features and configurations of the shoe, such as the inclusion of laces, the positioning of the top member for foot access, and the characteristics of the fixed and fold-back portions of the top member.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Ankle opening
(Claim 1, Claim 7, Claim 8, Claim 11, Claim 14, Claim 15, Claim 16)
“In one embodiment, the opening in the top member is located at one end of the shoe and sized so as to permit the leg or ankle of the wearer to extend therethrough.”An opening in the top member of the shoe that allows the ankle of the wearer to extend through.
Connection area
(Claim 1, Claim 7, Claim 8, Claim 11, Claim 14, Claim 15, Claim 16)
“According to one aspect of the invention, there is provided a shoe comprising: a sole having an upper surface and a lower surface; a top member having an outer surface and an inner surface and mounted on the sole, the top member and sole defining a space for receiving a foot, the top member further having an opening; and a fastener in the top member extending from the opening and continuing over the top member such that a portion of the top member is movable between a first position in which the space is substantially closed and a second position in which a portion of the top member is folded back from the sole to provide access to the space.”The area where the upper surface of the sole is connected to the lower connective edge of the top member.
Fixed portion
(Claim 1, Claim 7, Claim 8, Claim 11, Claim 14, Claim 15, Claim 16)
“The invention provides for a shoe having a base or sole, a top mounted on the sole so that sole and top together define a space for receiving a foot, an opening on the top, and fastening means whereby at least a part of the top may be selectively separated from the sole to allow the foot to be inserted into or removed from the shoe, and fastened to the sole when the foot is in the space defined by the shoe so as to keep the foot securely within the space.”A part of the top member of the shoe that remains in a fixed position when the fold back portion is moved to provide foot access.
Fold back portion
(Claim 1, Claim 7, Claim 8, Claim 11, Claim 14, Claim 15, Claim 16)
“According to one aspect of the invention, there is provided a shoe comprising: a sole having an upper surface and a lower surface; a top member having an outer surface and an inner surface and mounted on the sole, the top member and sole defining a space for receiving a foot, the top member further having an opening; and a fastener in the top member extending from the opening and continuing over the top member such that a portion of the top member is movable between a first position in which the space is substantially closed and a second position in which a portion of the top member is folded back from the sole to provide access to the space.”A part of the top member of the shoe that can be moved between a closed position and an open position to provide access to the space for receiving a foot.
Single fastening means
(Claim 1, Claim 7, Claim 8, Claim 11, Claim 14, Claim 15, Claim 16)
“In accordance with one embodiment of the invention, the top of the shoe is connected to the base or sole by means of a zipper extending from the opening toward the base and partly around the shoe.”A single, continuous zipper fastener used to open and close the shoe.
