Publication number: 20090193580Abstract: A bed mattress support apparatus and method includes a fluid filled bladder or multiplicity of bladders to vertically support a rigid platform. The rigid platform provides a suspended surface to support a mattress, foam pad, or other mattress-like device. A frame surrounds the bladder to prevent lateral movement of the bladder. Motion limiting features control vertical displacement of the platform.Type: ApplicationFiled: February 6, 2009Publication date: August 6, 2009Inventor: Derek K. Gauger

Publication number: 20090188041Abstract: An inflatable bed is adapted for use with a sofa, and includes an upper inflatable pad unit disposed on and connected to a lower inflatable pad body, and having a bridging unit that is misaligned from the lower inflatable pad body in a vertical direction and that has a bottom surface adapted to face a seat surface of the sofa when the bridging unit is disposed on the seat surface of the sofa. Two auxiliary inflatable pad bodies are attached respectively on opposite lateral ends of the bridging unit of the upper inflatable pad unit. Each auxiliary inflatable pad body is adapted to fill a space between the bridging unit of the upper inflatable pad unit and a corresponding arm of the sofa when the bridging unit of the upper inflatable pad unit is disposed on the seat surface of the sofa.Type: ApplicationFiled: August 18, 2008Publication date: July 30, 2009Inventor: Hsin-Tsai Wu

Patent number: 7565709Abstract: A double chambered transfer mattress is provided capable of partial deflation that that includes a top inflatable mattress and a bottom inflatable mattress that are separated by a common wall from one another. A selectable inlet/outlet valve is arranged for airflow communication between an interior chamber of the bottom inflatable mattress and a source of pressurized air. A one-way valve is positioned through the common wall so as to provide selective air flow communication between the top inflatable mattress and the bottom inflatable mattress so that when the inlet/outlet valve is closed, so that air continues to escape from perforations in the bottom inflatable mattress, the one-way valve is actuated so as to prevent deflation of the top inflatable mattress.Type: GrantFiled: April 15, 2008Date of Patent: July 28, 2009Assignee: Woodlark Circle, Inc.Inventor: David T. Davis

Publication number: 20090183313Abstract: A therapeutic mattress is providing including an encasing housing a base layer and a patient support layer in a cavity of the encasing. The base layer has a foam base member and foam side panels connected to the base member. The patient support layer is provided above the base layer and has a plurality of sections or zones. In one embodiment, a plurality of the sections are made of an inflatable component, and another of the plurality of sections are made of a non-inflatable component. In an alternate embodiment, each of the sections contains an inflatable component. In one embodiment, the zones of the patient support surface include a head zone adjacent a head of the mattress, a foot zone adjacent a foot end of the mattress, a seat zone adjacent the head zone, and a knee zone between the seat zone and the foot zone. A foam mattress is provided in the head zone, and an air mattress having a plurality of individual air cells fluidly interconnected is provided in the foot zone.Type: ApplicationFiled: March 23, 2009Publication date: July 23, 2009Inventor: Craig Poulos
