Air bedding system with diaphragm pump

An air bedding system comprising an air mattress, an air bladder confined within said mattress, an air blower confined within said mattress having an intake to atmospheric air and having an exhaust to atmospheric air and having a pressurized air outlet, an air line connected to the pressurized air outlet and connected to the air bladder, an air valve for selectively opening and closing air flow therethrough, means for actuating the air valve for opening air flow through the air line and for energizing the air blower, and means for actuating the air valve for opening air flow through the air line and allowing said air to exhaust to atmosphere, wherein wherein said air blower is comprised of a diaphragm pump comprised of a shaft, means for rotating said shaft at a speed of less than 3,300 revolutions per minute, a first flange assembly connected to said shaft such that the axis of rotation of said shaft forms an angle other than 90 degrees with the axis of rotation of said first flange assembly, a second flange assembly connected to said shaft such that the axis of rotation of said shaft forms an angle other than 90 degrees with the axis of rotation of said second flange assembly, a first connecting rod connected to a first diaphragm, a second connecting rod connected to a second diaphragm, a third connecting rod connected to a third diaphragm, a fourth connecting rod connected to a fourth diaphragm, and means for converting rotary motion of said flange assemblies into reciprocating linear motion of both said first connecting rod, said second connecting rod, said third connecting rod, and said fourth connecting rod, and wherein:

• (a) as said first connecting rod is moved in a first direction at a first rate of travel, said second connecting rod is simultaneously moved in a second linear direction at a second rate of travel, wherein said second rate of travel is equal to said first rate of travel, and said second linear direction is the opposite of said first linear direction;
• (b) as said third connecting rod is moved in a third direction at a third rate of travel, said fourth connecting rod is simultaneously moved in a fourth linear direction at a fourth rate of travel, wherein said fourth rate of travel is equal to said third rate of travel, and said fourth linear direction is the opposite of said third linear direction;
• (c) said first flange assembly is connected to each of said first connecting rod and said second connecting rod by means of a ball and socket assembly;
• (d) said second flange assembly is connected to each of said third connecting rod and said fourth connecting rod by means of a ball and socket assembly;
• (e) said first flange assembly is comprised of a first inner flange disposed within a first outer flange and separated from said first outer flange by first bearings;
• (f) said second flange assembly is comprised of a second inner flange disposed within a second outer flange and separated from said second outer flange by second bearings;
• and
• (g) Said first diaphragm communicates with a first inlet and outlet valve pair, said second diaphragm communicates with a second inlet and outlet valve pair, said third diaphragm communicates with a third inlet and outlet valve pair, and said fourth diaphragm communicates with a fourth inlet and outlet valve pair.
