Abstract:
A massage device, comprising:(a) two spaced-apart rollers, each having a cylindrical outer surface and an axis of rotation having first and second ends, each of said rollers respectively parallel to each other, said ends of each of said axes slidably mounted within a respective assembly including a journal in support of each of said axes of said roller; (b) a housing including a suction region thereof in communication with a source of negative pressure, said housing including an opening for communication with the human body, said opening also communicating with said suction region of said housing, said opening disposed within a lower surface thereof and further defined by variable positions of said axes of said spaced-apart rollers; (c) within said housing, a first reversible motor having selectably rotational or counter-rotational angular outputs, and control means for actuating each respective output by a single manual switch; (d) within said housing, gear assembly means powered by said first motor, for converting each of said angular outputs of said first motor into respective reciprocating linear movements to thereby vary said positions of said rollers and thereby vary a width of said opening of said housing, in which respective compressive and de-compressive functions are thereby provided to said spaced apart rollers; (e) within said housing, a second reversible motor having manually selectable respective rotational and counter-rotational outputs, and control means therefore; and (f) belt means, powered by said respective outputs of said second reversible motor, for communication to said axis of said rollers of selectably reversible mutually synchronous rotational and counter-rotational motion.
