Inflatable (e.g., Air Containing) Patents (Class 5/655.3)
  • Patent number: 6510573
    Abstract: An air cell pillow includes an air cushion and a cover. The air cushion is encased by a cover that has a top, bottom and four side panels arranged generally in a box shape. The top and bottom panels each have a first thickness and the side panels each have a second thickness. The first thickness is greater than the second thickness. The first thickness provides a smooth, continuous surface atop the independent air cells of the cushion and the second thickness allowing the pillow to readily collapse upon application of a load to the top and bottom panels. The air cushion has separate zones that may be independently adjusted to vary the resiliency in each zone. The cushion has a base sheet and a top sheet. The top sheet is molded in the form of a plurality of air cells that are secured to and extend outwardly from the base sheet.

  • Publication number: 20020162172
    Abstract: Disclosed is a 22″×72″ air cushion levitation apparatus that is used when a medical patient is required to be moved from a hospital bed to a gurney and ten to examination tables. The apparatus is placed under the patient on the bed, a pressurized air supply is then applied, causing the apparatus to vent air from the bottom of the apparatus which causes the apparatus to lift in the air on a cushion of air. An attendant can then glide the apparatus and the patient from the bed to the gurney without physical exertion. The air supply is then terminated and the patient is gently lowered onto the gurney and taken to an examination table. The same procedure is employed to return the patient to their bed.

  • Patent number: 6446289
    Abstract: An inflatable mattress capable of being folded or rolled into a small compact unit and unfolded or unrolled to a relatively flat or partially contoured body supporting condition. The mattress is comprised of an inner foam core of the type capable of being rolled or folded. An outer flexible and foldable fabric cover surrounds the foam core. Moreover, air spaces are formed in the foam core to allow a self-inflating when a valve on the mattress is opened. The mattress is air impervious and will remain inflated when the valve is closed. This construction also allows a deflating when the mattress is compressed and the valve is again opened. The mattress is characterized in that the major part of the upper surface area is provided with a plurality of closely spaced apart recesses formed in both the cover and the foam core and thereby define corresponding raised portions or projections between each of the recesses.

  • Patent number: 6230347
    Abstract: The use of particulate stuffings such as down or fiberfill in the construction of orthopaedic pillows has previously been limited due to formidable intrinsic difficulties: On a curved wedge of support, with natural turning movement of the sleeper, fiberfill will tend to “avalanche” downhill, settle and pack down to obliterate any initial toricity or inflected curvature. Hence the sleeper is awakened to refluff or to punch the missing inflection back into place. Though simple internal partitioning can initially delay the scenario, in due course nuisance fiber sequestering and impeded normal hand refluffing are the results. The present invention focuses on structurally overcoming these impediments to the orthopaedic use of particulate fillings. It notably provides a pillow that manifests to the sleeper as downy soft, and comfortingly restful.
