Abstract
A device for producing waves and body in hair comprising curling tongs having heatable leg elements. The heatable leg elements have a wave shape with decreasing amplitude. The amplitude decreases from a maximum at the scalp-contacting end of the heatable leg elements to substantially no amplitude at the other end of the heatable leg elements. Heat-reducing lips may extend from the scalp-contacting end of the device. In one embodiment, the heatable leg elements are arcuate and can pivot about an axis extending along each leg, respectively. A method of using the device to form waves and body in hair wherein the amplitude of the wave is greatest near the scalp and decreases along the length of the hair in the direction toward its tip.
Claims35
A device for shaping hair comprising first and second legs and first and second leg elements attached at corresponding ends of said first and second legs, respectively, each of said first and second leg elements including a heat-generating element and a surface for giving off heat to the hair, wherein (a) the leg elements are provided with a wave shape which extends with decreasing amplitude across the surfaces;
- (b) the wave shapes of the leg elements essentially complement each other so that when the surfaces of the leg elements adjoin each other, wave peaks of one leg element extend into wave valleys of the other leg element, and vice versa;
- (c) each leg element comprises first and second end edges, wherein the first end edge is formed to engage with a first end area of the respective first or second leg, which first end area is made of a heat-insulating material;
- and (d) the wave shape has its greatest amplitude at the first end edge, which engages with the first end area, and substantially no amplitude at the other end edge, for providing a wave pattern in the hair nearest the head such that the amplitude of the wave pattern decreases along the length of the hair in the direction towards its tip.
A handheld device for shaping hair, comprising:
- A. a first leg and a second leg, said first and second legs each having a holding portion and a head portion, said head portion having a toe edge and a heel edge arranged such that when the device is used, the toe edge is directed toward the scalp of a person whose hair is being shaped and the heel edge is directed away therefrom;
- B. means for pivotably connecting the holding portions of the first and second legs;
- C. a first leg element attached between the toe edge and the heel edge of the head portion of the first leg, said first leg element having a wave-shaped surface extending with decreasing amplitude in a direction from the toe edge to the heel edge;
- D. a second leg element attached between the toe edge and the heel edge of the head portion of the second leg, said second leg element having a wave-shaped surface extending with decreasing amplitude in a direction from the toe edge to the heel edge, and a wave shape that is complementary to the wave shape of the wave-shaped surface of the first leg element.
A method for creating volume in a person's hair, said method comprising the steps of:
- A. providing a hair shaping device having first and second leg elements wherein the first leg element has a wave-shaped surface extending with decreasing amplitude and the second leg element has a wave-shaped surface extending with decreasing amplitude and that is complementary to the wave shape of the wave-shaped surface of the first leg element;
- B. heating the first and second leg elements;
- C. positioning the heated leg elements over a tuft of a person's hair such that the wave-shaped surfaces of the leg elements having a maximum amplitude extend over portions of the hair strands nearest to the person's scalp;
- D. closing the leg elements over the hair tuft;
- and
- E. holding the hair tuft between the leg elements for a time sufficient to impart a wave in the hair that has a maximum amplitude adjacent to the person's scalp and a decreasing amplitude along the length of the hair strands toward the tips thereof.
