Abstract

A hair styling device is described that has a handle, an elongated, substantially cylindrical, heatable rod providing a curling surface and supported by the handle, a heater for heating the curling surface, a support spaced apart from the curling surface, and a rotatable member rotatable relative to the curling surface for wrapping hair around and in contact with the curling surface. The device has an opening in the rotatable member for receiving a section of a user'"'"'s hair, a motor for rotating the rotatable member, and a flexible, heat-resistant clamp supported by the support and extending from the support toward the curling surface for clamping hair against the curling surface.

Claims

1. A hair styling device comprising:

a) a handle;

b) an elongated, substantially cylindrical, heatable rod comprising a curling surface and supported by the handle, the rod having a proximate portion attached proximate to the handle and an opposed distal portion;

c) a heater supported by the handle for heating the curling surface of the rod;

d) a rotatable member supported by the handle and rotatable relative to the curling surface of the rod for wrapping a user'"'"'s hair around and in contact with the curling surface of the rod;

e) an opening in the rotatable member for receiving the user'"'"'s hair;

f) a motor housed within the handle for rotating the rotatable member;

g) a rotation direction selection switch on the handle for selecting direction of the rotation of the rotatable member supported by the handle;

h) three supports spaced apart from the curling surface of the rod, wherein the supports extend from the proximate portion of the rod to the distal portion of the rod and are connected together by an upper support element proximate to the distal portion of the rod, wherein there is sufficient spacing between the supports so substantially the entire curling surface of the rod is visible to a user; and

i) three flexible, heat-resistant clamps, wherein each clamp comprises a distal portion fixedly and directly attached to one of the supports and a proximate end spaced apart from the rod by about 0.1 to about 3 mm prior to placement of the user'"'"'s hair in the opening in the rotatable member, wherein the proximate end of each clamp can move bidirectionally and wherein each clamp is configured to clamp the user'"'"'s hair against the curling surface of the rod that is heatable by the heater.

2. The hair styling device of claim 1, wherein the curling surface of the rod is accessible 360 degrees around the rod.

3. The hair styling device of claim 1 comprising a hook at the opening of the rotatable member for engaging the user'"'"'s hair.

4. The hair styling device of claim 3, wherein the hook comprises elastomeric material.

5. The hair styling device of claim 3, wherein the hook comprises finger-like projections formed from elastomeric material.

6. The hair styling device of claim 1, wherein the clamps have a first cross sectional area proximate to the curling surface of the rod, and a second cross sectional area at the support, the first cross sectional area being less that the second cross sectional area.

7. The hair styling device of claim 6, wherein the clamps are proximate to the curling surface of the rod and are triangular in lateral cross section.

8. The hair styling device of claim 1 comprising a magnet on the rotatable member, a magnet sensor for positioning the opening of the rotatable member, and a controller for positioning the opening in the rotatable member to a selected position for receiving a user'"'"'s hair when the rotation of the rotatable member ceases rotation.

9. The hair styling device of claim 1, wherein the clamps are made of elastomeric material.

10. The hair styling device of claim 9, wherein the elastomeric material is silicone.

11. The hair styling device of claim 1, further comprising an optical sensor for detecting when hair has been removed from the curling surface of the rod.
