<p>A massaging apparatus (10) which utilizes an array of air inflatable bladders (A, B, C, D). The array is to be located in conjunction with a portion of the body of a human. The array can be mounted within a housing (172, 190, 280, 210, 230, 240) such as a flexible belt-type of device (172, 208, 210) or can comprise a rigid stand-type of device (190, 230, 240) within which is incorporated one or more pockets (192) in order to accommodate a human appendage such as a foot. A separate inflation apparatus (10, 232) is associated with the array which is to supply and extract pressurized air to and from the inflatable bladders. The inflation apparatus utilizes at least one opposed piston assembly (78, 80) so that when one piston (100, 102, 108, 110) is supplying pressurized air to certain bladders the other piston is extracting pressurized air from certain other bladders thereby achieving a sequence of alternating pressurizing and depressurizing which produces a desirable massaging effect on the human body.</p> |
