Abstract:
A cyclically driven, straightly and reciprocally moving massage device comprising:a base plate having two studs installed at an upper and a lower ends of a top surface thereof for pivotably mounting one of a sprocket-like and a pulley wheel-like driving disk and one of a sprocket-like and a pulley wheel-like driven disk, respectively; one of a cyclical chain and a timing belt being installed around a circumference of the driving disk; and the driven disk, the driving disk being driven to rotate by a motor at a rear side of the base plate; a base mounting box having a through hole passing through a center section thereof for being passed by one of the chain and timing belt; at least one secondary driving disk engagable with one of the chain and timing belt being pivotably mounted at an interior of the base mounting box; the secondary driving disks being positioned at a side and engaged with one of the chain and timing belt such that when the secondary driving disk is engaged with one of the chain and timing belt and is driven cyclically, power from the secondary driving disk is transferred synchronously; at least one secondary driven disk is pivotably mounted at a side of a corresponding driving disks such that when the secondary driving disks are driven to rotate around a fixing axis, the secondary driven disk consequently follow a fixing axial rotation synhronously; selective massage components are installed at a top surface of the secondary driven disk with top ends of the massage components projecting from a top surface of the base mounting box, the massage components are positioned directly against a back of the user such that when the secondary driven disks are driven to rotate synchronously, a continuous rotating massage operation is provided; wherein from above device, when the driving disk is driven to rotate, the chain will execute a cyclic movement and thus cause the massage component to rotate synchronously around a fixing shaft, and thereby the massage components not only move with the chain, but also rotate around the axis of the secondary driven disk.
