    Abstract: A hot air curling iron is provided which can alternately be used as a curling iron or used to heat a hair roller. It has a spoon that is separate from the spoon control lever, but which has a common pivot with it. A releasable detent connects them. The unit normally operates as a curling iron. However, when a roller is placed over the curling iron barrel, the roller prevents the spoon from pivoting upwardly, so pressure on the control lever serves to release the detent. The lower portion of the control lever then serves as a clamp to hold the roller in place. Inwardly projecting detents on the roller serve to lock it in position over the clamp with the openings in the clamp aligned with those in the roller, permitting free air flow.

  • Patent number: 5357988
    Abstract: A hair iron is designed to be used in straight-perming hair, especially straight-perming frizzled hair. The hair iron comprises a grip part and pressing members. Opposing surfaces of the pressing member for clasping and pressing hair have uneven faces which match each other. The uneven faces may cover the entire opposing surfaces of the pressing members or parts of them. The uneven faces give relatively large pressure on hair. Repetition of pressing and releasing hair with shifting the iron on the hair from the root to the tip causes the hair to be pressed in multiple directions so as to be deformed into a tiny waveform. Combining regular treatment with perming lotion, the repetition, and sliding the hair iron frictionally on the hair from the root to tip to stretch the hair makes the hair straight tidily.

  • Patent number: 5223694
    Abstract: A hair styling iron for selectively effecting hair straightening or curling includes a generally circular cross-section electrically heated barrel. A tongue is movable relative to the barrel for selectively clamping a strand of hair between the tongue and the peripheral surface of the barrel for curling hair wound therearound. The barrel comprises a first and second pipes each having a generally semi-circular cross section with a top rounded outer surface and a flat bottom outer surface. The pipes are movable relative to each other between a closed position where the flat bottom surfaces are kept in closed relation to each other and an open position where the bottom surfaces are spaced away from each other. In the closed position, a strand of hair can be held between the opposing flat bottom surfaces of the first and second pipes in order to substantially straighten or uncurl the hair. Thus, the hair styling iron can alone provides hair curling and straightening capabilities.

  • Patent number: 5120933
    Abstract: A curling iron has an elongated heating tube and a clamp secured to an end of the tube which is attached to a handle. The heating tube has at least one generally flat surface having a longitudinal depression between 0.003 and 0.008 inch deep generally in the center of the surface. In one embodiment, the tube has relatively wide top and bottom surfaces which each have such a depression, and relatively narrow, sharply rounded side surfaces having a radius between about 0.03 and 0.1 inch. The clamp has a relatively short clamping surface which extends over a portion of the length of the heating tube. Hair strands which are wrapped around the tube are not curled over the flat surface or surfaces of the tube. The depressed portions of the heating tube do not contact the straight lengths of the hair directly, so that the straight lengths absorb less heat from the tube, and normal operating temperatures are more easily preserved in the heating tube.

  • Patent number: 5091629
    Abstract: A hair curling iron and apparatus for heating same are provided. The hair curling iron is comprised of a pair of elongated heat conductive semi-cylindrical tubular barrels having an inner flat surface. The barrels have handles and are pivotally connected together whereby the flat surfaces of the barrels may be brought together enclosing hair between. When closed together, the outer shape of the barrels is round, around which the hair is wound to give a curling effect. The size of the barrels, however, is such that the curling iron can not be readily placed in the heating chamber of a conventional curling iron oven. Thus, the instant invention provides for a heat conducting plate having vertical heat conducting rods to be fixed to the top of the oven in heat transfer relationship therewith. The barrels of the curling iron are hollow and open-ended and fit over the heat-conducting rods whereby the curling iron may be heated.

  • Patent number: 4939340
    Abstract: A curling iron is provided which is easy to assemble and, so, more economical to manufacture. The unit is molded in two snap-together halves, one half being the bottom portion (divided axially) and the other half being the top portion, and a molded spoon. The molded sections would include all the parts except for the electrical components. The curling iron is assembled by inserting the electrical components in one half, snapping the two halves together, and then snapping the spoon into place over the upper half. The molded sections are formed of a high temperature thermoplastic material. This material is transparent to infra-red rays; and, so, if an infra-red heater is used, the rays can pass through the plastic and heat the hair directly.

  • Patent number: 4877942
    Abstract: A curling iron which has a handle, a barrel extending axially from the handle, a heater for the barrel, a spring-pressed, pivoted spoon for holding hair against the barrel, a spoon extension formed as part of and extending outwardly from the spoon, proximate to the handle, and a thumb button at the end of the spoon extension. At least the outer surfaces of the spoon extension and the thumb button are covered with a thermally-insulating plastic material, so that these surfaces are no longer hot to the touch. The inner surfaces are preferably not insulated; this permits heat conducted from the spoon to the extension to be harmlessly radiated away inwardly.
