Abstract

A hair styler generally comprises an upper arm, a lower arm, and a hinge. The upper arm includes an upper grip and an upper clamp head. The upper clamp head includes an upper hair contact surface. The upper hair contact surface is twisted relative to the upper grip. The lower arm includes a lower grip and a lower clamp head. The lower clamp head includes a lower hair contact surface. The lower hair contact surface is twisted relative to the lower grip. The hinge attaches the upper and lower arms together such that the upper and lower arms are openable and closeable relative to one another. The hair styler is configured to receive hair between the upper and lower hair contact surfaces when the hair styler is in a closed position.

First claim

What is claimed is:

1. A hair styler comprising:
an upper arm including an upper grip and an upper clamp head, the upper clamp head including an upper hair contact surface, wherein the upper hair contact surface is twisted relative to the upper grip;
a lower arm including a lower grip and a lower clamp head, the lower clamp head including a lower hair contact surface, wherein the lower hair contact surface is twisted relative to the lower grip; and
a hinge attaching the upper and lower arms together such that the upper and lower arms are openable and closeable relative to one another, wherein the hair styler is configured to receive hair between the upper and lower hair contact surfaces when the hair styler is in a closed position,
wherein the upper hair contact surface and the lower hair contact surface extend between sides of the upper clamp head and the lower clamp head, wherein the entirety of the upper and lower hair contact surfaces are smooth and free of any teeth, and wherein the sides of the upper clamp head and the lower clamp head include teeth along edges of the upper clamp head and the lower clamp head.

2. The hair styler of claim 1 , wherein the upper hair contact surface has a first twist angle and the lower hair contact surface has a second twist angle, wherein the first twist angle is equal to the second twist angle such that the upper and lower hair contact surfaces fit together when the hair styler is in the closed position.

3. The hair styler of claim 1 , wherein the upper hair contact surface has a first twist angle and the lower hair contact surface has a second twist angle, wherein the first twist angle and the second twist angle each are in a range of 60 degrees to 120 degrees.

4. The hair styler of claim 1 , wherein the upper clamp head includes a top and an upper clamp plate, the upper clamp plate including the upper hair contact surface and being angled relative to the upper grip.

5. The hair styler of claim 4 , wherein the lower clamp head includes a bottom and a lower clamp plate, the lower clamp plate including the lower hair contact surface and being angled relative to the lower grip.

6. The hair styler of claim 5 , further comprising a first insulation layer positioned between the upper hair contact surface and the top of the upper clamp head and a second insulation layer positioned between the lower hair contact surface and the bottom of the lower clamp head.

7. The hair styler of claim 1 , further comprising a heating system configured to deliver heat to hair positioned between the upper hair contact surface and the lower hair contact surface.

8. The hair styler of claim 1 , wherein the teeth include first teeth along the edge of the upper hair contact surface and second teeth along the edge of the lower hair contact surface, wherein the first teeth and the second teeth are arranged to engage each other when the hair styler is in the closed position.

9. The hair styler of claim 1 , further comprising an upper end grip at an end of at least one of the upper arm and the lower arm opposite the upper and lower grips.

10. A hair styler comprising:
a first arm including a first clamp plate including a first hair contact surface, wherein the first clamp plate is twisted;
a second arm including a second clamp plate including a second hair contact surface, wherein the second clamp plate is twisted;
a hinge attaching the first and second arms together such that the first and second arms are openable and closeable relative to one another, wherein the hair styler is configured to receive hair between the first and second clamp plates when the hair styler is in a closed position; and
a heating system configured to deliver heat to the hair positioned between the first and second clamp plates,
wherein the first hair contact surface and the second hair contact surface extend between sides of the first clamp plate and the second clamp plate, wherein the entirety of the first and second hair contact surfaces are smooth and free of any teeth, and wherein the sides of the first clamp plate and the second clamp plate include teeth along edges of the first clamp plate and the second clamp plate.

11. The hair styler of claim 10 , wherein the heating system includes a first heating element extending along the first clamp plate and a second heating element extending along the second clamp plate.

12. The hair styler of claim 10 , wherein the first clamp plate has a first twist angle and the second clamp plate has a second twist angle, wherein the first twist angle and the second twist angle each are in a range of 60 degrees to 120 degrees.

13. The hair styler of claim 10 , wherein the first arm further includes a first grip attached to the first clamp plate, the first clamp plate being angled relative to the first grip.

14. The hair styler of claim 13 , wherein the second arm includes a second grip attached to the second clamp plate, the second clamp plate being angled relative to the second grip.

15. The hair styler of claim 14 , further comprising a first insulation layer positioned along the first hair contact surface and a second insulation layer positioned along the second hair contact surface.

16. A hair styler comprising:
a first clamp head including a first hair contact surface, wherein the first hair contact surface is twisted;
a second clamp head including a second hair contact surface, wherein the second hair contact surface is twisted;
a handle attached to at least one of the first clamp head and the second clamp head; and
a hinge attaching the first and second clamp heads together such that the first and second clamp heads are openable and closeable relative to one another, wherein the hair styler is configured to receive hair between the first and second hair contact surfaces when the hair styler is in a closed position,
wherein the first hair contact surface and the second hair contact surface extend between sides of the first clamp head and the second clamp head, wherein the entirety of the first and second hair contact surfaces are smooth and free of any teeth, and wherein the sides of the first clamp head and the second clamp head include teeth along edges of the first clamp head and the second clamp head.

17. The hair styler of claim 16 , wherein the handle includes a first grip attached to the first clamp head and a second grip attached to the second clamp head.

18. The hair styler of claim 17 , wherein the first grip and the second grip each include an inner plate, wherein the inner plates are planar, the first and second hair contact surfaces being twisted relative to the inner plates.

19. The hair styler of claim 16 , wherein the first hair contact surface has a first twist angle and the second hair contact surface has a second twist angle, wherein the first twist angle and the second twist angle each are in a range of 60 degrees to 120 degrees.
