Air Mattress With Two Means Of Inflation/Deflation And A Method Of Relieving Pressure On The Primary Closure
US Patent:
2006023, Oct 26, 2006
Filed:
Apr 25, 2005
Appl. No.:
11/112596
Inventors:
James Metcalf - Jenison MI, US
International Classification:
A47C 27/08
US Classification:
005706000, 005709000
Abstract:
This is an inflatable cushion or mattress that is both easy to inflate and deflate by means of a large re-sealable opening. This opening is protected from bursting open due to the increased pressure caused, for example, by a large body lying upon the mattress. The means of protection is by pulling the primary closure under the mattress so that the pressure works against the walls of the mattress rather than against the primary closure. The primary closure is held in place under the mattress by a secondary closure made of hook and loop fabric. Furthermore, the cushion or mattress can have its internal air pressure finely adjusted by the use of a standard air valve incorporated into the mattress.
