Spinal column rehabilitation machine, has movable part moved up and down, so that hollow shaft is carried and rotator is moved up and down by crank to rotate and pivot rotator in different directions

摘要

The machine has a wheel set (30), whose rotary motion is transferred to longitudinal and transverse shafts. A rotator (80) shifts an eccentric rod (51) in a circular motion. A movable part (60) is moved up and down, so that a hollow shaft (70) is carried and the rotator is moved up and down by a crank to rotate and pivot the rotator in different directions. The hollow shaft has a slider (71) that slides along rails (63) of the part.
