Claims1

Dependent claims

A flexible multi-directional beauty salon chair comprising:

a chair, a first vertical rod extending downwardly from a seat of said chair and a horizontal base supporting the opposite end of said rod, the central portion of said rod forming an axle portion;
a supporting arm rotatably mounted on and extending horizontally from the axle portion of said first vertical rod said supporting arm having a first internal horizontal ring gear surrounding said axle portion, first motor means mounted on a partition board connected to said rod and having an output gear in meshed engagement with the internal ring gear for driving said arm in rotational movement around said rod;
a column extending horizontally from an end thereof from said supporting arm, a second threaded rod rotatably mounted horizontally within said column, a second ring gear fixedly mounted within said column adjacent said supporting arm and in meshed engagement with and surrounding an end portion of said second threaded rod, and second motor means engaging said second threaded rod for rotating the same relative to said second fixed ring gear;
a hanging arm mounted at an end of said column opposite said supporting arm and coupled to an end of said second threaded rod opposite said second ring gear, a third rod rotatably and vertically mounted on said hanging arm, said third rod coupled to said hanging arm at one end portion of said third rod the opposite end of said third rod portion being threaded, third motor means engaging said third rod for rotating said rod;
a working seat disposed above the threaded end portion of said third rod and a third internal ring gear fixed to the underneath of said working seat and in mesh with the threaded end of said third rod whereby activating said first motor means will cause said column, hanging arm and working seat to rotate horizontally about said chair, activating said second motor means will change the horizontal distance between said chair and working seat and activating said third motor means will move said working seat vertically.
