Abstract:
A massage apparatus comprising:an upright frame member having a parallel pair of vertically extending guide rails;an externally threaded screw shaft mounted on said frame member and disposed parallel to and between said guide rails;a slide frame extending between said guide rails and coupled slidably to said guide rails so as to be movable upwardly and downwardly along said guide rails, said slide frame having upper and lower frame parts;a motor mounted on said lower frame part of said slide frame;a massage drive unit mounted on said slide frame, said massage drive unit including an upright rotatable drive shaft having a lower end provided with a first gear and an upper end provided with a second gear, said massage drive unit further including a massaging roller assembly driven by axial rotation of said drive shaft for imparting a massaging action;a first transmission belt coupled to said motor and said first gear so as to enable said motor to drive said drive shaft to rotate axially, rotation of said drive shaft resulting in corresponding rotation of said second gear;a coupling unit mounted on said upper frame part of said slide frame, said coupling unit including a rotary member coupled threadedly and rotatable relative to said screw shaft, and driven rotatably by said second gear about axis of said screw shaft, thereby enabling said rotary member to move upwardly and downwardly along said screw shaft to result in corresponding upward and downward movement of said slide frame relative to said guide rails.
