Patent ID: 7387598

Claim:
A multifunctional portable pneumatic exercise device, comprising: a telescopic tube having a proximal end and a distal end; a distal wall mounted on the distal end of the telescopic tube, the distal wall covering the distal end; a first engaging member mounted on an exterior surface of the distal wall; a valve housing mounted on the proximal end of the telescopic tube, the valve housing defining an internal chamber therein, the valve housing having an inner wall contacting the proximal end of the telescopic tube, a plurality of openings being formed through the inner wall so that an interior region of the telescopic tube is in fluid communication with the internal chamber, the valve housing further having an outer wall; a second engaging member mounted on an exterior surface of the outer wall; first and second straps, each of the straps having an engaging portion for releasably engaging a respective one of the first and second engaging members, the first and second straps being adapted for selectively and releasably securing the telescopic tube to at least one body part of a user; and a plunger axially movable within the internal chamber, the plunger having an air passage formed therethrough; whereby the user may selectively position the plunger within the internal chamber to selectively cover a portion of the plurality of openings formed through the inner wall in order to selectively adjust fluid resistance associated with the user collapsing and expanding the telescopic tube for muscular exercise purposes.
