No. 320,566 Claims priority, application Germany, Oct. 31, 1962, S 82,254 17 Claims. (Cl. 132-40) The present invention relates to hair curlers.

Hair curlers are used for making permanent waves as well as in general for hair settings of many different types. In general, such hair curlers are of a generally cylindrical configuration and locks of hair are wound onto the hair curlers so that with the aid of suitable treating liquids a desired hair setting can be obtained.

Problems are encountered, however, with respect to holding the hair curlers in place as well as with respect to locating a large number of hair curlers very close to each other in a selected relationship relative to each other. At the present time, for example, it is necessary to use with hair curlers, rubber bands, hair pins, or the like which must be applied to the hair curler after the hair is curled thereon for the purpose of holding the hair curlers in place, and this attaching of a holding device to the hair curler is an extreme inconvenience not only because of the operations involved, but also because of the room required for carrying out these operations, this room oftentimes making it extremely diicult to locate the hair curlers close to each other. Some known hair curlers have as parts thereof fastening devices for fastening the curlers to the hair once the hair is curled thereon and such fastening devices may take the form, for example, of elongated bars which are pivoted at one of their ends to the curler and are swingable to and from the hair curler for locking and unlocking the hair curler, but such devices make the use of the hair curler extremely awkward and inconvenient because during curling of the hair it is necessary for such devices to project from the hair curler and these devices interfere with the convenient rapid performing of the operations. Some hair curlers have axially projecting elements which when the hair curler has been placed in the proper position are shifted inwardly to lock the hair curler to the hair, but these devices, of course, cause the assembly to take up much more space during curling of the hair thereon than when the hair curling is locked in position so that it is not possible with such devices to locate the hair curlers very close to each other and here again the operations are made awkward and inconvenient because of these axially projecting elements.

It is accordingly a primary object of the present invention to provide a hair curler which will avoid the above drawbacks.

Thus, it is an object of the present invention to provide a hair curler which will occupy the same space when locked to the hair as when the hair is curled thereon so that the structure of the invention is extremely convenient to use and makes it possible for a large number of hair c urlers to be located very close to each other.

A further object of the present invention is to provide a hair curler which can become securely fastened to and released from the hair by a simple quick manipulation which is very easy to perform.

Yet another object of the present invention is to provide a hair curler which is capable of accomplishing the above objects and at the same time does not interfere in any way with the thorough treatment of the hair by the treating liquids. In particular, the hair curler of the invention does not clamp the hair in a manner similar to clamping of hair by elastic bands, hair pins, or the like. This latter type of clamping, on the one hand, results in non-uniform treatment of the hair, on the other hand, introduces undesired nicks or bends in the hair, and furthermore often results in breaking of the hair. t

An additional object of the present invention is to provide a hair curler which is simple and inexpensive to manufacture from readily available plastic material which cannot be attacked by the chemical solutions used in the treatment of the hair.

It is also an object of the present invention to provide a hair curler the components of which will reliably remain assembled together.

Also, it is an object of the present invention to provide one type of hair curler suited for normal curls and another type which is particularly suited for pin curls or the like. The term pin curls is intended to refer to curls in the form of ringlets or the like which are curled abou-t an axis which extends perpendicularly with respect to the scalp, whereas normal curls have an axis which extends substantially parallel to the skin of the scalp.

It is furthermore an object of the present invention to provide a hair curler which will cling to the hair during Ithe curling of hair thereon so as to render the curling operation more convenient.

Still another object of the present invention is to provide a hair curler construction which makes it immaterial in which direction the hair curler is turned and immaterial whether the hair curler is held in one position or in a second position which is turned end-forend with respect to said one position.

With the above objects in view the invention includes, in a hair curler, an outer tubular member, having a wall formed with a plurality of openings passing therethrough, and an inner member located within said outer tubular member and being turnable therein. A plurality of ilexible springy prongs are xed to the inner member and project therefrom into at least some of the openings,

respectively, of the outer member. Thus, by turning of these members one relative to the other it is possible to control the extent to which the prongs project beyond the outer member, and these members are turnable one relative to the other between angular positions n one of which the prongs are completely retracted into the outer member and in the other of which the prongs project to a maximum extent beyond the outer member. Thus, with this structure of the invention it is possible when the prongs are completely retracted to curl the hair in the usual way, and when it is desired to fix the curler to the hair it is only necessary to turn the inner member so as to cause the prongs to project into the hair which surrounds the curler and thus x the latter to the hair. Since the inner member is located within the outer member and need only be turned relative thereto there are no elements projecting axially beyond the curler to interfere with the operations.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specic embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 shows one possible embodiment of a hair curler of the present invention in a side elevation;

FIG. 2 is an end view of the hair curler of FIG. 1;

FIG. 3 is a longitudinal sectional illustration of the hair curler of FIG. 1;

FIG. 4 is a schematic illustration of a possible variation of the structure of FIGS. 1-3;

FIG. 5 is a longitudinal sectional illustration of another embodiment of a hair curler according to the invention,

FIG. 6 is a longitudinal sectional illustration of a further embodiment of a hair curler according to the invention, and

FIG. 7 shows in elevation a hair curler particularly adapted for forming pin curls.

Referring to FIGS. 1-3, the hair curler illustrated therein includes an outer tubular member 1 which is of a generally cylindrical configuration and which has formed in its wall a plurality of openings 2 passing therethrough, as shown in FIGS. 1 and 3. These openings 2 can be uniformly or non-uniformly distributed over the outer tubular member 1.

In the FIGS. 1-3 a pair of inner members 3 are located in the interior of the outer tubular member 1, and these members 3 are freely turnable relative to the outer tubular member 1. As is particularly apparent from FIG. 3, each inner member 3 is located almost entirely within the outer member 1. Each member 3 is provided at one end with an outwardly directed annular flange 4, and these anges 4 respectively overlap and are located next to the end faces -of the tubular member 1, as shown in FIG. 3. Of course, whether or not the ends of the tubular member 1 are also anged is immaterial.

As may ibe seen from FIG. 6 it is also possible to a'rrange only one inner member 3 within the outer member 1 and in this case the inner member 3 has a flange 6 overlapping one end of the outer member 1 while theflange 4 at the other end of the hair curler is integral with the member 1. Of course, where a single inner member is provided, as shown in FIG. 6, this inner member will extend substantially along the entire length of the outer member.

The members 3 of FIGS. 1-3 are, of course, turnable independently of each other. A pair of pin-and-slot means respectively connect the members 3 to the member 1. Each pin-and-slot means includes a pin 8 fixed to an end face of the tubular member 1 and extending through an arcuate slot 7 formed in the ange 4 of each member 3 (FIG. 2), and at the exterior surface of the flange 4 the pin 8 has an enlarged head 9 of a cross-section greater than the width of the slot 7 which extends along a circle whose center is in the turning axis of the member 3. The members 1 and 3 are made of a springy yieldable plastic material so that it is possible for the enlarged head 9 of the pin 8 to yield and be deformed while being pushed through the slot 7 and the head 9 springs back to its original configuration after having passed through the slot 7 so that in this way the parts are reliably held in their assembled condition. Moreover, the length of the slots 7 determines the extent to which the members 1 and 3 can be turned one relative to the other, these members having relative to each other end positions where the ends of the slots 7 respectively engage the pin I8.

'I'he inner members 3 iit with a relatively large clearance in the outer member 1, and a plurality of flexible springy prongs 10 are fixed to the exterior surface of the members 3 and project therefrom into at least some o f the openings of the member 1, respectively, and in the position of the parts shown in the drawings these prongs 10 project substantially beyond the exterior surface of the `outer member 1. The prongs 10 may be formed integrally with the members 3 and can be uniformly or nonuniformly distributed thereover. With the embodiment of FIGS. 1-3 the prongs 10 of the pair of members 3 are oppositely inclined, which is to say the prongs 10 carried by one of the members 3 are inclined oppositely to the prongs 10 carried by the other of the members 3, and as it apparent from FIGS. 1 and 3, the tips of the prongs connected to one of these members 3 are directed toward the tips of the prongs 10 connected to the other of the members 3. Moreover, as is apparent from FIG. 1, the prongs extend helically with respect to the members 1 and 3, and in addition, it will be noted that the openings 2 are provided with surface portions which give these openings a configuration conforming generally to the directions in which the prongs 10 extend so that the prongs 10 shift Very easily through the openings 2. Thus, it will be seen that the two groups of prongs 10 are directed toward the center of the curler and thus when the members 3 are turned so as to extend the prongs 10 outwardly beyond the exterior surface of the member 1 these prongs 10 will enter into the hair on the curler in opposed directions providing a very secure connection of the curler to the hair.

In the embodiment of FIG. 7 where the curler is adapted to be used for making pin curls the lower end of the curler of FIG. 7 is adapted to be placed next to the scalp and in this case all of the prongs 10 are directed toward the scalp. The members 3 of FIGS. 1 and 3 can be turned in opposite directions for displacing the projections 1t) outwardly beyond the outer member 1 and it is clear that whether the curler is used in the position shown in FIG. 1 or turned end-for-end is immaterial. In yorder t-o retract the prongs 10 the members 3 are simply turned in the opposite directions, and these prongs 10 can Vbe retracted all the way into the outer member 2, the

clearance between the members 3, on the one hand and the member 1, on the other hand, being suiciently great to accommodate the prongs 10 in this clearance space. In order to facilitate turning of the members 3 the outer peripheries of the anges 4 are knurled. When the hair is curled on the curler the prongs 10 are entirely retracted so that they do not in any way interfere with the curling operations. In order, however, for the surface 11 of the curler to reliably remain connected with the tips of the hair so as to render the starting of the curling operations convenient to carry out, the exterior surface 11 of the tubular member 1 is provided with integral bristles 12 (FIG. 4) so that these bristles will reliably maintain the tips of the hair in engagement with the curler. As is apparent from FIG. 4 the bristles 12 are divided into at least two groups with the bristles of one group extending circumferentially in a direction opposite from the bristles of the other group. As a result of this feature the curler can be turned in either direction during the curling operations. Thus, the operator can hold the curler at either end and the curling operations will be efficiently carried out. After the hair has been curled -onto the curler the inner members 3 are turned so as to cause the prongs 10 to project into the hair for securely holding the curler on the hair. Of course, the extent to which the prongs 10 project from the outer member 1 can be regulated by the extent of turning of the members 3 relative to the member 1. Because of the flexibility of the prongs 10 they are easily bent into a position lying against the inner surface of the tube 2 and the outer surface ofthe members 3 when the prongs are completely retracted. The prongs 10 and the members 3 are made of a suitable plastic, such as polyethylene, for example, or any -other readily available plastic which will not be attacked by the chemicals and which has the desired flexibility and resiliency. It is, of course, possible to provide at the exterior surface of the members 3 cutouts 10 located behind the members 10 and receiving them when the members 10 are retracted (see FIG. so that with such construction the outer diameters of the members 3 can be approximately equal to the inner diameter of the member 1, and the play between the inner and outer members can be greatly reduced. In such a construction the cutouts would also extend spirally.

As is apparent from FIG. 5 the invention is also applicable to that type of curler which is not cylindrical but instead has a central portion of a minimum diameter and diverges from the central portion toward both ends. Such a construction is, of course, particularly suitable for permanent waves, and in this case the inner members 3 are solid rather than hollow and have the frustoconical configuration shown in FIG. 5. In this embodiment the flanges 4 at the ends of the members 3 are made relatively large and extend to a greater extent beyond the eX- terior surface of the outer member 1 so that it is easier to turn the members 3, and here again the outer peripheries of the lianges are knurled.

In all embodiments the liquid treating materials can ow freely through the curler so as to provide a thorough treatment of the hair, and also such treating uids include streams of Warm air used for drying. Thus, it will be seen that the members 3 of FIGS. l-3 are formed with openings 13 so that these openings together with the openings 2 provide for free passage of fluid through the curler, and in FIG. 5 the outer tubular member 1 is also provided with a large number of openings and the inner solid members 3 are formed with openings 14 of relatively large size passing therethrough so that even with the solid inner members 3 an unobstructed passage of treating uid is guaranteed.

In the embodiment of FIG. 6 the single inner member 3 is provided with prongs shown in FIG. 6, and While these prongs are not inclined toward one or the other of the ends of the curler they may be inclined in a manner similar to the bristles 12.

As has been mentioned above the embodiment of FIG. 7 is particularly adapted for making pin curls. This embodiment may have a single inner member 3, as was the case with FIG. 6, and FIG. 7 clearly illustrates how the prongs 10 of such construction extend spirally. The member 3 of FIG. 7 has a single flange 4 at its upper end, and this ange 4 is connected to the outer tubular member 1 through a pin-and-slot connection as described above. In this embodiment the lower end of the inner member, as viewed in FIG. 7, is integrally formed with an elongated projection of spiral configuration, so that when the member 3 is turned relative to the member 1 for causing the prongs 10 to project into the curler the prong 15 will also turn itself into the hair so as to provide a very secure connection of the pin curler to the hair.

It is to be noted that with the structure of the invention not only can a large number of curlers be placed very close to each other extending in any desired direction without any particular care being taken by the operator to grasp one or the other of the ends of the hair curler, lin addition, when it is desired to remove the hair curler the retraction of the prongs 10 all the Way into the rinterior of the outer tube, 1 makes separation `of the curl- Yers from the hair very simple and easy to carry out and prevents pulling of any hair with the curler.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of curlers differing from the types described above.

While the invention has been illustrated and described as embodied in hair curlers, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
