DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a permanent wave hair-curler and more particularly to a hair-curler permitting the obtainment of a large-area waving of a large part of the head of hair.
Many models of hair-curlers have been proposed which permit the obtainment of a waving of the hair. The hair-curlers generally used have however the drawback of permitting the waving of only a single lock at a time so that a large number of hair-curlers must be used.
There has been described in French Pat. No. 605,781 an apparatus for waving the hair which permits the obtainment of waves in relatively large parts of the head of hair. The waving apparatus described in this patent comprises two or more elements each formed by two parallel rods connected at a single end by a pin about which pivots a fork formed by two pointed rods each of which may be brought between the two rods of an element.
This device permits the obtainment of a wave by inserting the fork under the hair against the scalp. However, it is not very practical and is fragile and the maintenance of the closed-up position is imperfectly ensured unless there are provided heavy and complicated locking mechanisms which may become out of adjustment.
The applicant has tried to design a hair-curler which permits the obtainment of large-area waves in a large part of the head of hair and which is both strong, stable and capable of being immediately placed in position.
The permanent wave hair-curler according to the invention, which comprises sharp-pointed cylindrical rods capable of being brought under the hair parallel to the scalp, and rods capable of being disposed on the hair on each side of said sharp-pointed rods, is characterized in that it is formed by two separate parts one of which has said rods which may be brought under the hair while the other has said rods capable of being disposed on the hair, said parts being capable of being assembled in such a manner as to obtain a regular alternation of the rods disposed under the hair and the rods disposed on the hair.
Owing to this continuous alternation of inner rods placed under the hair and outer rods placed on the hair, it is possible to obtain a large-area waving of a large part of the head of hair.
The rods of each part are carried by a support element or base from which they extend in parallel directions, holes being provided in the base for the passage of the ends of the rods of the other part.
The two parts of the hair-curler are assembled simply and rapidly by the engagement of the pointed ends of the rods in the holes of the base of the other part whose diameter substantially corresponds to the diameter of the rods.
In a particularly simple embodiment of the invention, the two parts of the hair-curler comprise sharp-pointed rods connected to a base, each part being thus capable of performing the function of inner and outer rods. The holes are disposed in each base in the gaps between the rods so as to receive the ends of the rods of the other part.
In a preferred embodiment of the invention, the cylindrical rods are curved so as to match the curvature of the scalp corresponding to the zone in which the hair-curler is placed. This is the case in particular for hair-curlers intended to be placed in position on the parietal or occipital zone of the scalp, while the cylindrical rods of hair-curlers intended for the temporal zones may be less curved or rectilinear.
Preferably, whether the rods be rectilinear or curved and irrespective of the curvature of the cylindrical rods, the gaps between the rods and/or the diameters of the rods are variable in a given hair-curler so as to result in an unevenness of the waving of natural appearance.
In an arrangement of the invention of particular interest, the rods of the part intended to be applied, not under the hair of the concerned zone of the scalp but on top of the hair and in the gaps between the rods of the first part, are provided with rapid fixing means, and these rapid fixing means preferably comprise, at least on the base of one of the parts, slots which ter
