Patent ID: 7905237

Claim:
A hair braiding machine comprising: a housing, which includes a motor mounted therein, a controller controlling a driving force of the motor, and orbital holes formed at an upper end of the housing, wherein the upper end of the housing has two circles having identical diameters which open in a partly overlapping form; a pair of stationary rotors, which are installed at centers of the circles of each orbital hole such that orbital tracks are defined between the orbital hole and the stationary rotors, the stationary rotors are rotated in opposite directions by the driving force of the motor, and the stationary rotors have a plurality of insertion recesses along an outer circumference thereof at regular intervals; a plurality of movable rotors, which are inserted into the insertion recesses of the stationary rotors along the orbital tracks, the movable rotors make a circular motion along the orbital tracks by a rotating force of the stationary rotors, the movable rotors include a fastener at an upper portion thereof from which a hair holding unit holding hairs to be braided is coupled and decoupled; the hair holding unit has a hair holder, which has a ring at a first end of a rod extending from a grip, and into which the hairs to be braided are inserted; a hair holding arm, which has a predetermined length, the hair holding arm holds and retains the hairs inserted into the hair holder, the hair holding arm includes a holder slit formed in an outer circumference thereof in a longitudinal direction such that the hair holder can come in and out of the hair holding arm; a grasper, which is coupled to and communicates with an upper end of the hair holding arm, and grasps the hairs retained in the hair holding arm with elastic force so as to be prevented from escaping; and a coupler, which is formed at a lower portion of the hair holding arm and is detachably installed on the fastener of each movable rotor; and a guide, which is installed at intersections of the circles of the upper orbital hole, the guide changes a path of each movable rotor reaching one of the intersections in a diagonal direction by one of the stationary rotors to make a circular motion by means of the other stationary rotor; the guide includes a pair of swing plates and a swing lever, the swing plates are hinged at the intersections of the circles of the upper orbital hole and are installed so as to face each other on the orbital tracks; the swing lever is pivotably coupled at a center thereof, the swing lever is coupled to lower portions of the swing plates, allowing one of the swing plates to be pushed and rotated in one direction by one of the movable rotors reaching one of the intersections, and rotates the other swing plate in the other direction.
