ABSTRACT:
The disclosure relates to a collapsible flexible pump which includes an inflatable spring and framework. The inflatable spring framework is formed by attaching a layer of flexible material over selected exterior portions of the flexible material pumping chamber to form a passageway therebetween. Inflation of the inflatable spring framework via an inflation valve, results in the collapsed flexible pump distending into a three dimensional pumping chamber inscribed by the inflated spring framework. The pumping chamber includes appropriate inlet and discharge valves. By applying a compressive force to the pumping chamber, the volume of fluid within the pumping chamber is forced out through the discharge valve. The restoring tendency of the distended inflatable spring framework returns the pump chamber to the extended position on the returning intake stroke. A plurality of exemplary inflatable articles are disclosed.
