  • Patent number: 9737110
    Abstract: The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.

  • Publication number: 20170087764
    Abstract: The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second.

  • Publication number: 20170035148
    Abstract: An article of footwear including a sole and an upper with an exterior and interior surface, and one or more bladders which comprises at least one of the exterior or interior surfaces of the upper. The bladder comprising sheets of polyurethane or polyester film attached together to form an airtight seal. The article of footwear also includes a inflation mechanism for selectively introducing air in the one or more bladders. The inflation mechanism is located under the foot of the wearer to be activated by the normal action of the wearer to inflate the one or more bladders. The article of footwear may also include an assembly for connecting several tubes to one under foot inflation mechanism. The article of footwear may also include inflatable laces that are inflated by an underfoot inflation mechanism.

  • Patent number: 9339078
    Abstract: Customized, form-fitting athletic articles with a heat moldable material that a wearer may heat to soften after purchase to conform the heat moldable material so the contours of the wearer's body may provide many advantages for consumers, such as increased comfort, performance, or safety. The heat moldable material may be incorporated into the upper of an athletic shoe. The heat moldable material may be sufficiently flexible so as not to impede the necessary movements of a wearer or the athletic shoe while performing activities, such as running, walking, jumping, etc. The heat moldable material may be reusable in that it may be reheated and remolded multiple times so that the article may be re-customized or re-fitted as needed. The article may also include a temperature sensitive indicator that indicates when the heat moldable material has been softened.
