Abstract
An inflatable product includes a pack having a first vent with a first valve, a second vent with a second valve, a third vent in communication with the ambient, a first chamber in communication with the first vent, a second chamber in communication with the second vent, and an air pump pumping air into and out of the pack through the third vent when activated in a first and second direction. A first switch structure is movable between first and second orientations. The first orientation opens the first valve and activates the air pump in the first direction to inflate the first chamber. The second orientation closes the first valve. A second switch structure is movable between third and fourth orientations. The third orientation opens the second valve and activates the air pump in the second direction to deflate the second chamber. The fourth orientation closes the second valve.
