1. A portable body massager comprising:
a portable housing sized to be received and supported by a backrest of a conventional chair, the housing having a partially transparent external contact surface to receive a portion of a body of a user;
a longitudinal guide mounted in the housing;
a carriage oriented in the housing and cooperating with the guide for limited longitudinal translation in the housing along the guide;
a motor supported upon the carriage and operably coupled to the housing to translate the carriage along the guide;
at least one massage member supported by the carriage to impart a massage effect upon the portion of the user's body as the carriage is translated relative to the housing;
a light source provided on the at least one massage member to convey an illumination effect from the at least one massage member;
wherein the housing has a longitudinal axis;
wherein the motor is further defined as a first motor, the motor comprising a motor output shaft driven thereby, the motor output shaft being operably coupled to the housing to translate the carriage along the guide;
wherein the at least one massage member comprises at least a pair of massage members transversely spaced about the longitudinal axis;
a second motor supported upon the carriage in operable communication with the at least a pair of massage members to drive the at least a pair of massage members relative to the carriage to provide a kneading massage effect to the user's body corresponding to a longitudinal orientation of the carriage and a gearing mechanism for user-selected operation of the at least a pair of massage members relative to the carriage providing selective orientation adjustment of the at least a pair of massage members relative to the longitudinal axis independently of translation of the carriage along the guide so that the user selects a stationary orientation of the at least a pair of massage members to impart the massage effect;
a transmission comprising:
a worm mounted to and driven by the motor output shaft;
a worm gear rotatably mounted to the carriage and operably driven by the worm;
a pinion gear rotatably mounted to the carriage and operably driven by the worm gear;
a longitudinal rack affixed to the housing and engaged with the pinion gear such that rotation of the pinion gear translates the carriage along the guide;
wherein the orientation adjustment of the at least a pair of massage members is controlled from a control pad; and
wherein operation of the first motor further comprises user-selected rotation to translate the carriage to a desired longitudinal orientation.
