3,019,798 H CURLERS Augusta Gaget, 29 Rue dEchallen, Oyonnax, France Filed Dec. 23, 1958, Ser. No. 782,523 Claims priority, application France Jan. 8, 1958 2. Claims. (Cl. 132-42) The present invention relates to hair curlers of the kind comprising a cylindrical mandrel on which a tress of hair is wound, this tress being retained on the said member by any appropriate retaining means, as for instance by a resilient rubber thread or by an elastic clip.

In accordance with the present invention the periphery of the mandrel is formed with a plurality of rows of transverse arcuate ribs, the curvature of each row being inverted with respect to the next one.

In a tress of hair which has been treated by the improved hair curler the successive ribs on which the tress has been wound have imparted thereto an undulated or crimped appearance which adds its effect to the conventional curl or wave appearance.

According to a further aspect of the present invention the mandrel of the hair curler is tubular and its outer periphery comprises spaced longitudinal rod portions which may be smooth or provided with small transverse ribs, and intermediate rows of arcuate ribs, as above eX- plained. Such a curler may conveniently be made of an appropriate plastic material.

The invention still concerns a hair curler as above described, wherein the mandrel has a plain closed end and an open end, which open end is adapted to receive an end cover, and the hair retaining member is formed of rubber threads attached to said cover and to said closed end, so as to be stretched along the periphery of the curler mandrel when the end cover is engaged in said open end.

In the annexed drawings:

FIG. 1 is a side view of a hair curler according to this invention with the end cover removed laterally.

FIG. 2 is a longitudinal section thereof with a tress of hair wound thereon, the end cover being disposed in position.

FIG. 3 is an elevation or side view corresponding to FIG. 2.

FIG. 4 is an enlarged cross-section taken along line 1V1V of FIG. 1.

FIG. 5 is a fiat representation or development of the peripheral wall of the hair curler.

The hair curler illustrated comprises a tubular mandrel with an open end and a closed end, a removable end cover and a rubber or like longitudinally resilient flexible member returned on itself in U-formation to connect the said cover with the closed end of the said mandrel.

The mandrel itself is formed of an elongated end cup 1 integral with four longitudinal rod portions 2 of substantially semicircular section, as shown in FIG. 4, the said rod portions being connected with each other in succession on the periphery of the curler by longitudinally spaced transverse arcuate ribs 3.

As illustrated in FIG. 4, as seen in a transverse plane ribs 3 are arcuate substantially co-axially with respect to the mandrel, and, as illustrated in FIGS. 1 and 5, they are also arcuate on the cylindrical periphery thereof. Moreover in each of the successive longitudinal rows comprised between successive rods 2, they are parallel to each other or, in other words, the inner side of their curvature is facing towards the same end of the curler mandrel, and their disposition is inverted in a row with respect to the next one. In the flat representation or development of FIG. 5 row A has its ribs with their inner side facing towards the left, while in row B the inner side is facing towards the right, in row C towards the left and in row D (which is shown as cut in two halves) towards the 3,19,798 Patented Feb. 6, 1962 right again. The ribs of the successive rows thus form a longitudinal succession of spaced parallel transverse undulations on the periphery of the curler mandrel.

The open end of the curler mandrel has its edge formed by the last one of the above mentioned undulations, i.e. by an endless transverse succession of four ribs. In FIG. 5 this edge has been referenced 3a.

The curler cover 4 is in the form of an elongated cylindrical cup of such a diameter as to fit into the open end of the curler mandrel. The periphery of cover 4 has an outer rib 5 adapted to engage the edge of the open end 3:: of the curler mandrel and this outer rib is undulated on the cylindrical periphery of cover 4 as the said edge itself in order to fit against the latter, as clearly shown in FIG. 3.

The hair curler further comprises a resilient thread 6, made for instance of a rubber core associated with a covering braid, which is transversely passed through holes 40! formed in the periphery of cover 4, its ends being in turn passed through holes in, (FIG. 4) formed in the periphery of end or cup 1 and being attached to each other within the latter as shown at on (FIGS. 2 and 4). Thread 6 thus forms a resilient connecting loop between cover 4 and the curler mandrel proper. The length of this connecting loop is besides such that by resiliently extending same, cover 4 may be engaged into the open end of the curler mandrel, both sides of the said loop then extending longitudinally against the periphery of the curler mandrel.

In use, cover 4 being disengaged from the curler mandrel, as illustrated in FIG. 1, a tress of hair 7 is wound around the latter, as indicated in FIGS. 2 and 3, and cover 4 is re-engaged into the open end thereof, whereby both sides of the loop formed by thread 6 are resiliently pressed onto trees 7 which is thus retained on the curler.

The hair is thus pressed against ribs 3 and it is caused thereby to assume a zig-zag formation against the latter, whereby the tress is given an undulated or crimped appearance which cannot be obtained by means of the known hair curlers of the prior art.

The curler mandrel and the end cover thereof are conveniently made of thermoplastic material.

I claim:

1. A hair curler comprising an elongated substantially cylindrical mandrel formed on its periphery with a plurality of substantially longitudinal rows of transverse ribs, said ribs being substantially parallel to each other in each of said rows and being arcuate on the periphery of said mandrel, the inner curvature of the ribs of the successive rows facing around said mandrel alternately towards one and the other end thereof to produce thereon a substantially sinusoidal transverse pattern; and means to retain a tress of hair on said mandrel to compel said tress to assume a substantially sinusoidal shape, between the successive ribs of the successive rows.

2. In a hair curler as claimed in claim 1, said mandrel being formed of spaced rectilinear parallel rod portions longitudinally disposed about a common geometrical axis, and the ribs of each of said longitudinal rows of ribs extending transversely between two successive rod portions with the curvature of the ribs in the plane defined by said two successive rod portions to connect same with each other.
