3 Claims. (Cl. 132-40) The present invention relates to a hollow hair curler which is round in cross-section and the ends of which are provided with securing teeth for securing the curler, inclusive of a wound-up strand of hair.

Hair curlers of this kind are known wherein, at one end of the hair curler, anchoring teeth ascending approximately helically in the axial direction are arranged at one end of the curler. Theses known curlers are secured in the hair in a position perpendicular with respect to the scalp, after the winding-up of the hair strand by a rearward rotation, the result of which is that the obliquely directed securing teeth which ascend in the axial direction become anchored in the hair and thus secure the curler therein.

It has been found that the fact that the wound hair strands stand vertically is inexpedient for many hair styles. Furthermore, when it is required to release the anchoring teeth in order to remove the curler tom the hair, the curler must be rotated and this may result in damage to the wound curl.

Known furthermore is a hollow hair curler with anchoring teeth and having anchoring teeth the points of which are directed towards each other at both ends. The curler sleeve is made from resilient material, so that the curler can be extended in a way similar to a tension spring. In order to wind the strand of hair, the curler must be extended. After the winding up of the hair strand, the two curler ends are allowed to move towards each other again, for the purpose of securing the teeth and the hair together. This curler is relatively complicated in manufacture and use. Furthermore, in consequence of the fact that the curler has teeth directed towards each other at both ends, the removal of the curler from the curl formed is extremely difficult. For this purpose, the curler must again be extended and the curl then wound off from the curler sleeve, with the result that the curl formed is damaged.

It is an object of the present invention to overcome the above disadvantages.

According to the present invention there is provided a hollow hair curler which is round in cross section and the ends of which are provided with comb-like securing teeth which are integral extensions of the curler, the teeth at one end of the curler being bent over, slightly spaced apart from the outer surface of the curler, and pointing in the direction of the other end of the curler, and the teeth at said other end of the curler pointing in a direction away from said one end.

When using the curler according to the invention, the said curler is disposed in a position tangential with respect to the scalp and transversely of combed-out hair strands and then the hair strands are wound in the conventional manner from the tip about the hollow-cylindri-- cal part of the curler, towards the roots of the hair and as near the scalp as is desired. After the winding of the hair strands, the curler is displaced axially by a distance corresponding approximately to the length of the teeth, this displacement being towards the end provided with the bent over securing teeth. Then the curler is again moved back approximately the same distance. This reciprocating movement of the curler has the result that the securing teeth at both ends of the curler engage in the Patented Sept. 28, 1965 side portions of the lock of hair so collected, so that the curler is held fast in its position in consequence of the fact that it is secured at both ends. As soon as the lock of hair is dry and no longer adheres to the curler, the curler can be readily drawn-out of the curl in the direction towards the end carrying the bent over securing teeth without damaging the curl.

In this way, a horizontal or lying hair coil or curl, such as is necessary for a number of hair styles is formed, and furthermore there is no possibility of this curl being damaged when the curler is removed. Furthermore, the winding-up of the lock of hair and also the release of the curler from the curl is an easy matter, without it being necessary when so doing to extend or draw apart parts of the curler.

Fundamentally, it is possible to only partially provide the periphery of the curler ends with securing teeth. In order, however, to obviate the necessity to carry out a supplementary rotational or winding movement for achieving the anchoring state between the teeth and the hair, according to a further proposal of the invention the comb-like securing teeth extend uniformly distributed about the entire periphery of the curler.

If the securing teeth are slightly outwardly curved at least at one end of the curler, it becomes possible to dispense with the otherwise necessary-above all in the case of a thick, wound-up strand of hair-slight tilting movement of the curler before securing is efiected, so as to displace the securing teeth as far as the hair bed.

The curler according to the invention has the further advantage that, above all, its teeth are designed as extensions of the hollow-cylindrical curler portion and are extremely suitable for the taking out and combing out of smaller portions of the hair, for example of the strands to be wound on. In this manner, the hair curler can be used as an auxiliary means for preparing the strand to be Wound, so that it is unnecessary to use a comb as a second implement. A further advantage resides in the fact that the hair curlers which are at the moment not required can, with the aid of their teeth arranged slightly spaced from the hollow cylindrical curler part, quite readily be engaged in the hair, so that it is unnecessary to lay them down. The curler according to the invention can be made from any desired material. Preferably, it is made of plastic with its surface polished. This has the advantage that, due to the electrical charging of the smooth curler, extremely good adhesion of the hair on the curler is achieved.

Embodiments of the invention are illustrated in the drawings, wherein:

FIG. 1 shows a lateral view of the invention;

FIG. 2 is a longitudinal section of to the invention; and

FIG. 3 shows an elevational view of the embodiment illustrated in FIG. 1 from the end which is not provided with bent-over teeth.

The curler has a hollow-cylindrical curler portion 1. The curler portion 1 is provided at one end with comblike securing teeth 2 extending in the axial direction of the curler. At the lower curler end as shown in FIGS. 1 and 2, the comb-like anchoring teeth 2 are designed as extensions of the hollow cylindrical curler portion 1. Comb-like bent over securing teeth 3 at the other curler end extend equidistantly spaced from the outer periphery of the hollow cylindrical curler portion 1.

As will be seen from FIG. 2, the comb-like securing teeth 2, which are designed as extensions of the curler portion 1, are curved out slightly. However the securing teeth 2 can also be inwardly curved, this having the advantage that, after securing in the hair, unintentional release of the hair by slippage is prevented.

a curler according to a curler according As will be clear in particular from FIG. 3, the comblike securing teeth 2, 3 extend in uniform distribution about the entire periphery of the curler.

After winding-up of the strands of hair on the hollowcylindrical curler portion 1, the hair curler is first of all displaced in the direction of the bent over securing teeth 3 by a distance corresponding approximately to the length of the teeth 2 or 3, whereafter it is then again moved back by the same distance. This reciprocal displacement has the result that the securing teeth 2, 3 of the curler engage in the hair, so that in this way the two ends of the curler are secured or anchored.

I claim:

1. A hair curler comprising a hollow substantially cylindrical body having opposite ends, a first set of teeth integral with said body at one of said ends and extending generally axially from the body, and a second set of teeth encircling the body at the other of said ends and extending in the same direction as the first set of teeth, the second set of teeth being integral with the body, said body having a smooth surface between said sets of teeth.

2. A curler as claimed in claim 1 wherein the teeth of each set have uniform spacing circumferentially of said body.

3. A curler as claimed in claim 1 wherein the teeth of at least one set are slightly inclined in a radial direction.
