Roller massaging device

A roller massaging device comprising:

• a casing;
• a main shaft vertically extending and rotatably inserted through the casing;
• a rotary table having a central portion coupled to an upper end of said main shaft;
• a plurality of rotors rotatably provided above a top face of said rotary table by means of subordinate shafts each extending in parallel with said main shaft;
• massaging rollers positioned above the rotors eccentrically with said subordinate shafts;
• a rotor operating system for causing said rotors to rotate around said respective subordinate shafts;
• a rotary table operating system for causing said rotary table to revolve around said main shaft while said rotors and said respective subordinate shafts do not rotate relative to the rotary table;
• and
• driving means for activating either one of said rotor operating system and said rotary table operating system, wherein
• said rotor operating system comprises individual gears formed around said respective rotors, said main shaft rotatable with respect to said rotary table, a central gear engaged in said individual gears and fixed to the upper end of said main shaft, and a first transmission gear fixed to said main shaft in a position below said rotary table,
• said rotary table operating system comprises a combination of said rotor operating system and a second transmission gear fixed to a back face of said rotary table so that said second transmission gear can rotate with respect to said main shaft, said second transmission gear having the same number of teeth as said first transmission gear,
• said driving means has a motor and a drive shaft driven by the motor, and switching means for switching between the case where power of the drive shaft is transmitted only to said first transmission gear and the case where the power of the drive shaft is transmitted to both of said first and second transmission gears, and
• said switching means comprises first and second drive gears each fixed to said drive shaft provided in parallel with said main shaft, and a slider for vertically moving said driving means inside said casing, whereby
• if said slider is operated to move said drive shaft downward, said second drive gear comes to mesh only with said first transmission gear, and if said slider is operated to move said drive shaft upward, said first and second drive gears come to mesh with said first and second transmission gears, respectively.
