Multi-chamber inflatable device

摘要

A multi-chamber inflatable mattress includes a main air chamber, upper and lower peripheral air chambers, and an upper air chamber. The main air chamber includes internal tensioning structures which cooperate with a bottom mattress panel and a lower intermediate panel to provide a generally box-shaped, mattress-sized inflatable structure upon pressurization. A second, upper intermediate panel cooperates with a top mattress panel to define an upper air chamber which defines the sleeping surface. The main air chamber receives pressurized fluid directly from a valve, while the lower and upper peripheral air chambers are in direct fluid communication with the main air chamber but not the valve. The upper air chamber is in direct fluid communication with the upper peripheral air chamber, but not the main chamber or valve.

主权项

1. A multi-chamber inflatable mattress comprising:
a bottom panel; a top panel spaced from the bottom panel and defining an upper sleeping surface of the mattress; a peripheral panel bonded to the bottom panel and the top panel to define an internal mattress cavity; an upper intermediate panel disposed between the top panel and the bottom panel; a lower intermediate panel disposed between the bottom panel and the upper intermediate panel; a valve in fluid communication with the internal mattress cavity such that the mattress can be inflated and deflated via the valve; a main air chamber bounded by the bottom panel, the top panel and the peripheral panel, the main air chamber in direct fluid communication with an ambient atmosphere via the valve; an upper peripheral air chamber disposed at a periphery of the top panel, the upper peripheral air chamber in direct fluid communication with the main air chamber and in secondary fluid communication with the ambient atmosphere; and an upper air chamber disposed between the top panel and the upper intermediate panel, the upper air chamber in direct fluid communication with the upper peripheral air chamber, in secondary fluid communication with the main air chamber and in tertiary fluid communication with the ambient atmosphere.
