Patent ID: 7048701

Claim:
A lie-down massager, comprising: a) a base frame having an elongated top panel, wherein an elongated opening is formed centrally and lengthwisely through the elongated top panel; b) a rider provided below the elongated top panel of the base frame; c) a guide member movably engaged between the base frame and the rider so as to enable the rider to make a horizontally reciprocal movement relative to the base frame; d) a lifter having a top portion and a bottom portion, wherein elongated guides extend marginally from the bottom portion of the lifter, wherein the elongated guides are releasably received by guide bushes formed on top of the rider to stabilize a vertically reciprocal movement of the lifter relative to the rider; e) a shaft rotatably engaged to the rider, wherein the shaft is eccentrically connected to a cam disk so that the shaft rotation generates an eccentric rotation of the cam disk, wherein the cam disk is defined by an inner disk section, an outer ring section, and ball bearings circularly provided between the inner disk section and the outer ring section, wherein an outer rim of the outer ring section abuts to the bottom portion of the lifter, whereby the shaft rotating further generates the vertically reciprocal movement of the lifter relative to the rider in accordance with the eccentric rotation of the cam disk while the outer rim of the outer ring section of the cam disk oscillatingly abuts to the bottom portion of the lifter; f) massage bumps attached to the top portion of the lifter and moving vertically and/or horizontally along the elongated opening of the elongated top panel of the base frame; and g) a pad covering the massage bumps and the elongated opening of the base frame.
