United States Patent ice 3,498,300 SLEEVE TYPE HAIR CURLER Bernard J. Lehn, T. L. Cantley, 7635 Ben Ave., North Hollywood, Calif. 91605 Filed Sept. 7, 1967, Ser. No. 666,119 Int. Cl. A45d 2/00 U.S. Cl. 132-40 1 Claim ABSTRACT OF THE DISCLOSURE The device is a two piece hair curler of the type having a spring clip for holding the hair to the curler. The improvement resides in the configuration of the clip which is a U-shaped member normally having one leg on the inside and one on the outside of the curler. The inner leg is conigurated to have bends in it to provide a part of substantial extent that lies juxtaposed against the inside surface of the inner member of the curler, the configuration of the clip being such that in the unstressed condition the said part of the inner leg of the clip lies against and parallel to the outer leg.

Basically, the use of hair curlers is conventional and well known. In the type of hair curler concerned with herein, the hair is clipped or secured to a cylinder or mandrel by means of a spring clamp or clip having the shape of a bobby pin. The spring clip is carried by a second sleeve or cylinder which is insertable into and retractable from the rst cylinder. To appreciate the nature of the improvements of the invention, the technique of use of this type of hair curler should be understood. The spring clip is generally of U-shape and normally with the inner sleeve inserted into the outer sleeve, one leg of the clip is on the outside of the outer sleeve and the other leg is on the inside of the inner sleeve. In the technique of use, with the parts of the curler in this position, strands or tresses of hair are wound around the curler on the outside of the outer leg of the spring clip. (More than one spring clip can be used if desired.) The hair is wound around the curler until the curler is down to the scalp. The inner sleeve is then withdrawn, drawing the outer leg of the spring clip out from underneath the hair. The inner sleeve is then rotated until the spring clip is next adjacent to the scalp in which position, the spring clip, having a particular shape as will be described hereinafter, the outer leg tends to move outwardly away from the curler so that when the inner sleeve and the spring clip with it are now inserted into the outer sleeve, in this position, the outer leg of the spring clip engages hair between itself and the outer sleeve. When the inner sleeve reaches its inner position the action of the spring clip deriving from its particular shape causes the outer leg to move toward and adjacent the outer cylinder so as to clip or clamp the hair between itself and the outer sleeve of the curler. One of the principal objects of the invention is to provide a configuration of spring clip or clamp such that the result just described can be realized as will be described in greater detail hereinafter.

Another object is to provide a hair curler as described wherein the spring clip is generally of U-shape, the inner leg having a bend relatively close to the yoke of the spring clip with an intermediate portion normally lying parallel to and closely adjacent to the outer leg. This shape makes possible results as described above.

Another object is to provide a hair curler as described wherein the Sleeves are made of a moldable material, such as plastic, having embedded therein metal particles such that the sleeves have attraction for the hair which becomes negatively charged while curling so that the hair clings to the curler as desired, and so that the particles Patented Mar. 3, 1970 in the sleeves can retain heat and thereby promote drying of the hair.

Another object is to provide a hair curler as in the foregoing wherein the utilization is improved by providing one or more axial grooves on the inside of the inner cylinder to guide the inner leg of the spring clip, or clips.

Another object is to provide a hair curler as described wherein the inner and outer sleeves are provided with apertures which are in alignment transversely as respects the sleeve to allow straight through or transverse ow of circulating air.

Further objects and additional advantages of the inyention will `become apparent from the following detailed description and annexed drawings wherein:

FIGURE 1 is a side view of a preferred form of the invention with the inner sleeve retracted;

FIGURE 2 is a view similar to that of FIGURE l with the inner sleeve partially inserted;

FIGURE 3 is an enlarged sectional view of the curler with the inner sleeve inserted;

FIGURE 4 is a sectionalview transverse to the axis of the curler;

FIGURE 5 is a partial sectional view like that of FIG- URE 3 with the inner sleeve in partly retracted (or nserted) position;

FIGURE 6 is a View of the preferred form of spring clip used;

FIGURE 7 is a partial sectional view of a curler wherein the sleeves have metal chips embedded therein.

Referring to FIGURES 1 to 6, numeral 10 designates the outer sleeve, numeral 12 the inner sleeve, and 14 designates the spring clip or pin of the curler. The sleeve 10 is cylindrical and may be made of suitable material, preferably plastic. At one end there are external knurls 16 which facilitate grasping the curler for rotating it as will lbe described. At its other end, the sleeve 10 has an internal end rib or flange 11. 'I'he sleeve 10 has apertures in it as designated at 20 which are preferably arranged so that apertures in opposite sides are transversely aligned to facilitate circulation of air laterally through the curler. See FIGURE 4.

The sleeve 12 is of similar construction, preferably being made of light weight material such as plastic. Its diameter is slightly less than that of the sleeve 10 as may be seen in FIGURE 3. At its inner end there is provided an external rib 24 which is able to engage against rib 18 on the inside of the sleeve 10, these parts preventing the inner sleeve from being entirely withdrawn. At the left end of the sleeve 10 are two external knurled ribs 30 and 32 slightly spaced from each other, these ribs providing a grip to facilitate holding the curler when being used as will be described. Between these ribs at one point in the circumference there is provided an aperture designated at 34. The spring clip is held in this aperture. The spring clip 14 Iresembles a bobby pin. It is a U-shaped spring member having an outer leg 36 and inner leg 38 extending from the yoke or U-bend part 40. Preferably the ends of the legs are encased in hardened plastic 42 and 44 which forms a smooth bead or bulb on the ends of these legs to prevent injury to the scalp or fingers in use. The inner leg 38 has a bend in it as designated at 46 spaced from the U-bend 40 so that in the unflexed condition of the spring clip it has an intermediate portion which lies parallel to and juxtaposed against the other leg 36. (See FIG. 6.) At the end of the leg 38, it has an inwardly bent part 52 so that normally the ends of the two legs are spaced from each other to provide for easily inserting something between them and opening the clip.

FIGURE 6 shows a preferred form of clip or holding pin. The configuration can be varied in having bend 46 spaced farther from the U-bend, the shape otherwise being the same or substantially the same.

On the inside of sleeve 12 as shown in FIGURE 4, there is a guideway provided by two closely spaced axial ribs 54 and 56, the aperture 34 being a position between these ribs at the left end of the sleeve 12. The clip 14 is in a position as shown with its U-bend 40 in the aperture 34 with one leg on the outside of the sleeves and the other leg on the inside. The sleeves 10 and 12 are formed or fabricated preferably to have metal chips such as aluminum chips as designated at 60 and 62 in FIGURE 7 molded therein. The purpose of these chips isthat is has been found that when the curler is in nse the hair becomes positively charged electrically and is attracted by the metallic chips embodied in the sleeves. Further these metal chips retain heat and facilitate the drying of the hair when the curlers are in position. The curler can of course be made without embedding metals chips.

Referring to FIGURE 4, additional axial ribs 62-68 are provided on the inside of sleeve 12 to provide guideways for additional spring clips, apertures being provided for these clips similar to the aperture 34. A single spring clip may be used with the curler or optionally more than one may be used.

The technique of use of the curler is as follows. The primary purpose of the inner sleeve is that of holding the spring clip and facilitating its manipulation. In use, the inner sleeve is inserted into the outer sleeve. With the curler in position spaced from the scalp or head, tresses of hair are then rolled or wrapped around the curler by rotating it, the hair wrapping around the outside of the' outer leg 36 of the spring clip 14. When the curler has been rotated or rolled down to the scalp, the inner sleeve 12 is then retracted, that is, pulled out and it is then rotated relatively to the outer sleeve 10 to bring the spring clip 14 into position next to the scalp. The'inner sleeve is now inserted into the outer sleeve, the outer leg 36 of the spring clip clasping the tresses of hair that are between the scalp and the curler. The clip 14 is particularly congurated to facilitate this purpose. As the inner sleeve is inserted the outer leg 36 of the spring clip 14 rst takes the position as shown in FIGURE wherein the action tends to spread the legs of the spring clip in the manner shown. This facilitates the engaging and clasping of the hair between the outer leg of the spring clip and the curler. As the inner sleeve moves from the position of FIGURE 5 to the fully inward position of FIGURE 3, the outer leg moves inwardly towards the curler with a snap action, clasping the hair as shown in FIGURE 3,

this snap movement being accompanied by an outward snap movement of the U-bend 40 of the clip in the aperture 34. The curler is now in position.

From the foregoing those skilled in the art will readily understand the nature and utility of the invention and the manner in which it achieves and realizes the objects and advantages as set forth in the foregoing.
