  • Patent number: 5433505
    Abstract: An adjustable seat or back cushion to provide comfort and support for a sitting individual has an outer fabric cover with a front panel and a back panel forming an enclosure. The cover has a zippered opening which provides selected access to the enclosure. At least one support pad formed from compressible material with a first predetermined configuration and a first ILD is designed to be inserted through the opening and selectively located in the enclosure adjacent the front panel. A plurality of other support pads also formed of compressible material having at least one other predetermined configuration and ILD different than the configuration and ILD of the first support pad can be inserted through the opening and selectively located between the first support pad and the rear panel. The support pads are located in adjacent, surface-to-surface contact to create a tiered structure within the cushion.

  • Patent number: 5136751
    Abstract: A wheel assembly designed to be adhesively attached to an article. The assembly includes a mounting plate having an upper surface with an adhesive layer and a peel-away protective cover. The cover is designed to be removed to reveal the underlying adhesive layer. The mounting plate further includes a center portion and side portions which are pivotal relative to each other to enable the mounting plate to be adhesively attached to adjacent surfaces of the article. A pair of legs are formed in one piece with the mounting plate and extend away from the bottom surface. Each of the legs has a front edge and a rear edge. The front and rear edges of the legs are inwardly offset from the front and rear edges of the mounting plate to prevent the mounting plate from separating from the article. The pair of legs and the bottom surface of the mounting plate between the legs define a wheel channel. A relatively rigid insert is located within and conforms substantially to the wheel channel.
