HAIR CURLING EQUIPMENT This invention relates to an improved hair curling de vice for forming a permanent wave of hair. More particularly, this hair curling device is intended to hold hair wound on the hair curling rod from unwinding.

BACKGROUND OF THE INVENTION Heretofore there have been hair curling rods to which a rubber ring is axially applied for securing hair in wound state on the rods. However in such rods, when chemical liquid for a permanent wave is applied to the hair, such chemical liquid tends to stay in the portion where hair is in contact with the rubber ring, with hair in this portion becoming injured. For this reason, the portion of hair contacting the rubber ring is often set into an irregular pattern because it has not been regu larly rolled along the circumference of the hair curling rod.

Also as the rubber ring holds the hair near the root, it is impossible to slide the rod with hair wound therearound for performing desired hair style.

SUMMARY OF THE INVENTION One object of the present invention is, by use of the device of the present invention, to uniformly apply cold permanent wave liquid to hair so that liquid will not remain in some parts to badly affect a portion of hair.

Another object is to curl hair in rollers along the circumference of the cylindrical rod.

A further object of the present invention is to furnish a hair curling device in which the rod wound with hair may be freely slided in its axial direction so that any desired hair style may be easily formed.

A still further object of this invention is to fix the hair curling rod with hair wound around it in a stable position with a simple operation so that the rod with hair will not unwind by spring action of hair.

To achieve these objects of the present invention, the device of the present invention is constructed of a combination of a cylindrical hair curling rod and a stick so as to securely fix the hair curling rod to a position on the head. One end of the stick forms an arcuate holder for engaging the outer circumference of the rod and the other end of it forms a pin to be inserted into the hair.

Other object and advantages of the present invention will become more apparent from following description with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a hair curling device of the present invention showing the method of using FIG. 2 is a perspective view of a stick that is a part of the assembly of the present invention.

FIG. 3 is a perspective view of a hair curling rod that is the other part of the assembly.

FIG. 4 is an enlarged cross section of the rod shown in FIG. 1.

FIG. 5 is a perspective view of the assembly showing an alternative mode to that shown in FIG. 1.

FIG. 6 is a perspective view showing the use of the assembly in which the hair curling rod is different in-art from the rod shown in FIG. 3.

FIG. 7 is a perspective view showing the use of the assembly in which the hair curling rod is different in part from the rod in FIG. 6.

FIG. 8 is a perspective view showing the use of a conventional hair curling rod.

FIG. 9 is an enlarged cross section of the rod in FIG. 8.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, numeral 1 represents a cylindrical hair curling rod, its outer diameter being gradually smaller from its ends toward the middle. A plurality of perforations 2 in a radial direction are provided near the ends of the rods and indent stripes 3 in a axial direction are formed at the ends. An arcuate holder 4 to fit the outer diameter of the end portions of said hair curling rod 1 is integrally made with a pin 5 forming a stick 6. At the inside of said holder 4, there are provided

projections

7 and 8 adapted to engage the grooves of indent stripes 3. 9 is a finger nip to be nipped by fingers when the arcuate holder 4 is to be expanded against its spring force.

As shown in FIGS. 1 and 4, when a lock of hair 10 growing from the head 11 is wound in a direction A10 around the hair curling rod 1, in this position, the arcuate holder 4 of stick 6 is engaged with the indent stripes 3, then in spite of the spring of hair 10, the hair curling rod 1 is stabilized and will not turn in a direction opposite that of arrow A10.

With the spring action of hair, if the rod 1 turns in a direction opposite that of arrow A10, such turning is prevented as the tip of pin 5 abuts against head 11.

Also as the

projections

7 and 8 provided at the inside of the arcuate holder 4 of stick 6 engage the indent stripes 3 axially provided at the ends of rod (FIGS. 3, 6) or with slits 12 (FIG. 7), the hair curling rod 1 is constrained from turning relative to the holder 4.

Alternatively, as shown in FIG. 5, the stick 6 may be inserted through the perforations 2 provided near the ends of the rod, so that turning of the rod is also prevented.

A conventional hair curling rod 13 is shown in FIGS. 8 and 9. 14 is a rubber ring. Other numerals represent same structures as in FIGS. 1-7.

In such a hair curling rod, as a lock of hair 10 wound around the rod is locally held with the rubber ring 14, chemical liquid for permanent wave tends to remain on this portion of the rubber ring, and thus the hair 10 therearound is locally injured.

This invention is not limited to the above embodiments. Any alteration or modification may be made within the scope of the claims and without departing from the spirit of the invention.

What is claimed is:

1. A hair curling device comprising:

a stick having a straight pin portion;

a cylindrical rod having an outer portion on each end thereof and an inner portion therebetween, attaching means being provided on at least one of said outer portions for cooperating with said stick to hold said stick non-rotatably with respect to said rod with said pin portion projecting in a direction substantially perpendicular to the longitudinal axis of said cylindrical rod;

said stick having cooperating means thereon for cooperating with the attaching means of said rod;

such that a lock of hair can be wrapped on said inner portion and said stick attached to said outer portion without contacting said lock of hair.

2. A hair curling device in accordance with claim 1 wherein said attaching means comprises a plurality of longitudinal indented stripes disposed on at least one of said outer portions of said cylindrical rod and said cooperating means comprises an arcuate holder with projections disposed on the interior thereof for engaging said longitudinal indented stripes, said pin portion extending tangentially from said arcuate holder.

3. A hair curling device in accordance with claim 1 wherein said attaching means comprises a plurality of holes around the circumference of at least one of said outer portions, each of said holes being the same longitudinal distance from the end of said outer portion, said pin portion of said stick being capable of passing through two of said holes.

4. A hair curling device in accordance with claim 1 wherein said inner portion has a lesser radius than said other portion.

5. A hair curling device in accordance with claim 2 wherein said stick further includes a finger nip disposed on said arcuate holder near the end thereof opposite said pin portion.

6. A hair curling device in accordance with claim 1 wherein the radius of said cylindrical rod gradually increases from the center of said inner portion to the outer end of said outer portions along the longitudinal axis of said cylindrical rod.

7. A hair curling device in accordance with claim 6 wherein said inner portion has disposed thereon a plurality of longitudinal slits.

8. A stick for preventing unrolling of hair rollers con sisting of:

an arcuate portion;

a plurality of projections disposed on the interior of said arcuate portion; and

a pin portion tangentially attached to one end of said arcuate portion.

9. A stick in accordance with claim 8 further comprising:

a finger nip disposed near the other end of said arcuate portion.
