Abstract
A device for automatically curling hair includes a dome-shaped housing having an inlet opening and a longitudinal axis. A fixed rod having a heater therein is immovably positioned coaxially within the housing. A driving rod is positioned within the housing at a location radially outwardly spaced from the fixed rod and is rotated in a path about the fixed rod. A spiral-shaped member is positioned eccentrically about the fixed rod and has an end fixed to the driving rod. Rotation of the driving rod causes the spiral-shaped member to eccentrically rotate about the fixed rod.
Claims9
A device for automatically curling hair, said device comprising:
- a dome-shaped housing having an inlet opening and a longitudinal axis;
- a fixed rod immovably positioned coaxially within said housing;
- heating means immovably positioned within said fixed rod;
- a driving rod positioned within said housing at a position spaced radially outwardly from said fixed rod;
- a spiral-shaped tape-like member positioned within said housing and eccentrically about said fixed rod, said spiral-shaped member having at least one end fixed to said driving rod;
- and
- driving means, operatively connected to said driving rod, for moving said driving rod in a path coaxially about said fixed rod, and for thus rotating said spiral-shaped member eccentrically about said fixed rod, thereby creating a suction through said inlet opening, such that the combined action of said rotating spiral-shaped member and said suction operates to wind a lock of hair, introduced into said housing through said inlet opening, around said fixed rod.
