Abstract
A variable diameter adjustable hair tool that includes a barrel with a number of plates. A heater included in the hair tool may transfer heat at a specified temperature to the plates. The heater may draw power from a power unit. The hair tool has a handle connected to the barrel that allows the user to hold the tool. The adjustable diameter is achieved by an actuator that alters the outer diameter of the barrel by changing the distance between a surface of the plates and a central axis of the barrel. The actuator may controlled by a control component that converts a user action into an action of the actuator. Other aspects are also described and claimed.
Claims5
A variable diameter adjustable hair tool, comprising:
- a handle,
- a barrel connected to the handle on a distal end of the barrel, wherein the barrel comprises a plurality of plates, wherein each plate of the plurality of plates is rectangular in shape and each plate of the plurality of plates has a curvature such that the plurality of plates fit together in a cylindrical shape,
- a heater disposed within the barrel and connected by a thermally conductive path to the plurality of plates,
- a first actuator on the distal end of the barrel, wherein the first actuator is connected to each of the plurality of plates on a distal end of each of the plurality of plates and is disposed to push or pull the distal end of each of the plurality of plates to a desired distance from a central axis of the barrel,
- a second actuator on a proximal end of the barrel, wherein the second actuator is connected to each of the plurality of plates on a proximal end of each of the plurality of plates and is disposed to push or pull the proximal end of each of the plurality of plates to a desired distance from the central axis of the barrel, and
- the first actuator operates separately from the second actuator, and the second actuator operates separately from the first actuator, such that the first actuator independently adjusts a diameter of the distal end of the barrel, and the second actuator independently adjusts a diameter of the proximal end of the barrel.
