  • Publication number: 20070287938
    Abstract: A hand-portable manually operated back-massager, the U-Massage™ implement comprises a rigid frame critically configured as to facilitate a unique advantageous transitional-fulcrum principle, —whereby user can easily induce a much greater amount of massage-pressure and acupressure as well if desired. The basic notion of my transitional-fulcrum employs a gliding shoe mounted at the lower-terminus of my inverted J-shaped implement's front-leg, whereby the user is enabled to merely tilt the upper portion of the implement forward as to thereby realize a tremendous leverage advantage upon their back as the masssage-roller arranged at the lower-terminus of the implement's back-leg is caused to thrust into the user's back-musculature with far greater emphasis as compared to conventional back-massagers of this sort.
