  • Publication number: 20120084999
    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: 20110265347
    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.

  • Patent number: 7784116
    Abstract: A padded garment having at least one pocket with at least one pad located within the at least one pocket. The at least one pad has a plurality of interconnected, spaced apart tubes. A first end of each of the spaced apart tubes are interconnected along a first pathway and a second end of each of the spaced apart tubes are interconnected along a second pathway. The first and second pathways are recessed from a top plane and a bottom plane of the pad in areas between adjacent tubes such that the pad is flexible along the recessed areas of the first and second pathways and substantially less flexible along a length of the spaced apart tubes. The pad is shaped to correspond to an area of a wearer's body it is intended to cover.

  • Publication number: 20100178445
    Abstract: A stretchable appliqué made from a stretchable substrate with indicia thereon may be applied to a variety of articles including stretchable performance athletic wear. A method for making the stretchable appliqué may include applying an adhesive and a carrier layer to one surface of a stretchable substrate. Indicia may then be applied to the opposite surface of the stretchable fabric and the stretchable substrate may be cut to a desired shape to form the stretchable appliqué. The carrier layer may then be removed and the stretchable appliqué may be adhered to the desired article. The stretchable appliqué may be adhered to stretchable articles of apparel so that the appliqué may stretch when the article of apparel stretches. The carrier layer may be less stretchable than the stretchable substrate, including being completely non-stretchable.

  • Publication number: 20100126661
    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: 20090165333
    Abstract: A cushioning member for an article of footwear. The cushioning member is a flexible bladder having a fluidly interconnected heel chamber and forefoot chamber. The bladder is disposed above the sole and beneath the wearer's foot to provided added cushioning to the wearer. The bladder contains air at slightly above ambient pressure and can be formed by thermoforming or by welding two sheets of resilient, flexible material together. A connecting passage fluidly connects the heel chamber and the forefoot chamber. The connecting passage is narrow to control the flow of air between the two chambers.
