Richard Fraige has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4607404
    Abstract: Hydraulic chambers for attenuation of wave motion within waterbed mattresses are buoyed by encapsulated material made of a large multiplicity of interbonded fibers.
    Type: Grant
    Filed: July 13, 1984
    Date of Patent: August 26, 1986
    Inventor: Richard Fraige
  • Patent number: 4602396
    Abstract: A flotation sleep system for a liquid filled bed wherein a sheet of closed cell polyethylene foam bonded to a foamed layer is provided between the ticking of the bed and the watermattress. This arrangement prevents the collection of moisture or condensation on the watermattress and prevents the growth of mildew thereon.
    Type: Grant

    Date of Patent: July 29, 1986
    Inventor: Richard Fraige
  • Patent number: 4523343
    Abstract: Hydraulic chambers for attenuation of wave motion within waterbed mattresses are buoyed by unencapsulated material made by binding expanded foam beads to a garnetted fiber matrix.
    Type: Grant
    Filed: September 26, 1983
    Date of Patent: June 18, 1985
    Inventor: Richard Fraige
  • Patent number: 4496623
    Abstract: The fiber product includes a large multiplicity of fibers bound together with a binder. The binder also secures a quantity of buoyant particles, such as expanded foam beads, to the fibers. The buoyant particles render the product as a whole buoyant.The fiber product is manufactured by adding an adhesive and buoyant particles to a quantity of garnetted fibrous material, and curing the adhesive to bind the fibers and particles together.
    Type: Grant

  • Patent number: 4481248
    Abstract: A buoyant fiber product and method of manufacturing same. The fiber product includes a quantity of fibers which are bound together with a binder. The binder also secures a quantity of buoyant particles, such as foam beads, to the fibers. The buoyant particles render the product buoyant. The fiber product is manufactured by adding an adhesive and buoyant particles to a quantity of fibrous material. Upon curing of the adhesive, the fibers and particles are bound together.

  • Patent number: 4479275
    Abstract: An improved waterbed mattress with adjustable hydrostatic wave absorption comprising an outer water-inflatable bag-like enclosure provided with an inner wave-absorbing water bladder. When a user sits or lies on a conventional waterbed an undesirable wave front is created in the water contained in the waterbed mattress. The inner wave-absorbing water bladder of the present invention absorbs and diminishes this wave front and shifts its phase. The water bladder also changes its shape vertically and horizontally to block off the wave front and substantially seals off the balance of the enclosure from wave movement.

  • Patent number: 4301560
    Abstract: An improved adjustable waterbed mattress with hydrostatic wave absorption comprising a water-inflatable bag-like enclosure containing therein a non-woven or very loosely woven expanded fiber product, unbonded or fixed with a binder to the same or another fiber product, which resists decomposition in water. When a user sits or lies on a conventional waterbed there is a tendency to sink or bottom out especially on the edge and an undesirable wave front is created in the waterbed mattress. The provision of the subject expanded fiber product in the waterbed mattress of the present invention substantially mitigates and dissipates this wave front and allows the bed to be easily packaged, filled, heated, drained and stored.

    Inventor: Richard Fraige
  • Patent number: 4221625
    Abstract: An improved water mattress can be fabricated by a method which involves folding a rectangular sheet of thermal plastic material into a smaller rectangular sheet to form a dual-layered sandwich having three open edges; thereafter lap-sealing these three open raw edges to form a flat closed envelope, open at its corners; subsequently cutting specific sized rectangular notches in each corner of the envelope whereby the several apexes of each notch can be separated to form an overlapping slit which is reinforced with a separate piece of vinyl that is integrally bonded with the laps of the slit while it is in its stretched condition to completely seal the mattress.
