Filed:

Jul 27, 2000

Appl. No.:

09/626434

Inventors:

Brian L. Guthrie - Bradbury CA

Assignee:

Gaymar Industries, Inc. - Orchard Park NY

International Classification:

A61G 700

US Classification:

25112904, 5713, 13762412, 137875

Abstract:

An alternating pressure valve system is provided comprising a blower with an air intake and an air outlet; a rotor valve assembly connected to the air outlet from the blower where the rotor valve assembly comprising: a housing with an air intake, a first air outlet, a second air outlet, and a circular chamber; and a wedged shaped rotor valve rotatably contained within the circular chamber of the housing such that the rotor valve can rotate to partially block the first air outlet, partially block the second air outlet, or block neither air outlets; The rotor valve is preferably controlled by a gearmotor and pressure sensors to detect the relative pressure in each outlet.

International Classification:

A61G 7057
A47C 2710

US Classification:

5453

Abstract:

An air-filled mattress with virtually no air loss has a plurality of air-filled bags grouped into zones of uniform air pressure. A controller monitors the air pressure in each zone and activates a blower to adjust the pressure in any zone in which the measured pressure differs from the desired pressure by more than a threshold amount. The blower is otherwise deactivated. The bags are deflated by reversing the direction of flow from the bags to the blower. The bags are fastened to a mattress base using an attachment fitting that receives an elongated bead on the bag's bottom edge into a chamber along the mattress base fitting. The mattress base can be attached to any of a variety of different conventional bed frames. Tabs fastened to the mattress base having a hinge and a hand malleable aluminum plate can be bent to grasp a variety of different bed frames. A unique air manifold between the blower and the bags, a unique hose coupling between the blower and the manifold and a unique air coupling between the manifold and the bags are also described.
