Abstract:
1. A lie-down massager, comprising: a) a base frame having an elongated top panel, wherein an elongated top opening is formed centrally and lengthwisely through the elongated top panel; b) a rider provided below the elongated top panel; c) a pair of pulleys linked by a rope and respectively mounted in a front end portion and a rear end portion of the base frame, wherein a predetermined portion of the rope is fixedly attached to the rider so that the pulley rotation enables the rider to generate a horizontally reciprocal movement along the elongated top opening; d) a pair of roller coasters parallel to each other and attached to the base frame, wherein the roller coasters each have a substantially waved top surface; e) a coasting member liftedly engaged on top of the rider, wherein a coaster guide roller is formed outwardly extending from each side surface of the coasting member, wherein the coaster guide roller enables the coasting member to make a roller coasting movement on and along the waved top surfaces of the roller coasters; f) a lifter having a top portion and a bottom portion, wherein first elongated guides extend marginally from the bottom portion of the lifter, wherein the elongated guides are releasably received by first guide bushes formed on top of the coasting member to stabilize a vertically reciprocal movement of the lifter relative to the rider, wherein second elongated guides downwardly extending from the coasting member, and wherein second guide bushes upwardly formed on the rider to releasably receive the second elongated guides so as to stabilize the roller coasting movement of the coasting member along the roller coasters and the lifting of the coasting member from the rider; g) a gear unit including a bolt gear downwardly extending from the bottom portion of the lifter, an elongated nut type gear having a circular outer periphery, a first gear incorporated on and along the circular outer periphery, and a second gear engaged to the first gear and connected to a motor attached to the coasting member, wherein the bolt gear is releasably engaged in the nut type gear whose bottom end is rotatably attached to and supported by the coasting member, whereby the second gear rotation generates the first gear rotation and the subsequent rotation of the nut type gear enables the lifter to make a vertically reciprocal movement in accordance with the releasable engagement of the bolt gear and the nut type gear; h) massage bumps attached to the top portion of the lifter and moving vertically and/or horizontally along the elongated top opening of the elongated top panel of the base frame; and i) a pad covering the massage bumps and the elongated top opening of the base frame.
