Application September 16, 1954, Seriai No. 456,435

21 Claims. (Ci. 132-40) The present invention relates to hair curlers and has particular reference to that type of curler adapted to be self-applied by the wearer.

Amongst the general objects of the invention are: to provide a novel and improved form of curler which will enable the hair to be curled to be applied to the curler and held in a position such as to be curled closely to the head of the wearer; to provide a curler which may easily and readily be self-applied by the wearer; to provide a curler which alfords ample ventilation for the hair curled thereon to facilitate the drying thereof, and

to provide a device which is not only simple but relatively inexpensive to manufacture.

For a better understanding of the manner in which the above and other and more detailed objects hereinafter appearing may be obtained and of the advantages to be derived from the invention, reference may best be had to the ensuing portion of this specification, taken in conjunction with the accompanying drawings forming a. part hereof, which discloses diiferent embodiments of structure for carrying the invention into effect.

In the drawings, Fig. l is an exploded perspective view showing the two components of one embodiment of the invention.

Fig. 2 is a perspective view of one of the components with a tress of hair wound thereon.

Fig. .3 is a perspective view of the components shown in Fig. 1 partially assembled with a tress of hair wound on one of the components as shown in Fig. 2.

Fig. 4 is a perspective view of the fully assembled device comprised of the components shown in Fig. 1 and retaining in place a tress of hair wound on one of the components.

Fig. 5 is a section taken on the line 55 of Fig. 4.

Fig. 6 is a perspective view of a difierent form of one of the components shown in Fig. 1. i

Fig. 7 is a section similar to Fig. 5, showing another form of one of the components illustrated in Fig. 1.

Fig. 8 is a perspective of another form of device ernbodying the invention, and

Fig. 9 is a section taken on the line 9-9 of Fig. 8.

Referring now more particularly to Figs. 1 to 4, the device comprises a component 10 in the form of a core or supporting member, which in the embodiment illus- In accordance with the principles oft-he invention, the core is elastically resilient and preferably of a porous material of sponge-like form such as natural or artificial sponge rubber, expanded cellulose or suitable expanded forms of known plastics of the vinyl family, etc.

A component 12 in the form of a clamping or retaining member comprises a plurality of

elongated fingers

14, 16, 18 and 20 extending substantially in parallelism from a connecting collar or ring portion 22 at one end of the member, the latter being cylindrical in form and of a diameter adapted to slide over one end of the core member 10.

The member 12 may be formed of any suitable elastically resilient material, which may be of metal but which preferably is formed of an elastic type of thermoplastic material, such as the group of cellulose derivatives such as cellulose acetate, methyl methacrylate and other such materials having appropriate elastic physical properties.

if made of metal, the member 12 is advantageously of some form of light-weight non-corrodible metal or provided with some form .of non-corroding finish, since in its normal use the member will be subjected to moisture for substantial periods of time.

As will be observed from Fig. 1, the

fingers

14 and 16 of the retaining member 12 provide between themselves a relatively narrow elongated slot or gap 24 which advantageously tapers along its length from a wider portion at the free ends of the

fingers

14 and 16 to a narrower portion at the end of the member where the fingers join the collar 22.

The application of the device will be more or less evident from consideration of Figs. 1 to 5. The desired tress of hair to be curled, which is sometimes referred to as a section of hair and which is indicated at 26 in Fig. 2, is first wound around the .core member as shown in Fig. 2. Thereafter the retaining member or component 12 ,is forced longitudinally over the core member and its wound tress of hair, as indicated in Fig. 3, the base portions 26a of the tress of hair being firmly retained in the gap 24 between the

fingers

14 and 16.

It will be understood that the diameter of the ring portion 22 of the retaining member will be so related to the diameter of the core 14? that when the retaining member is forced over the core and its wound tress of hair, the core member will be compressed and/or the retaining member will be elastically expanded so as to firmly grip and retain in place the tress which is wound on the core.

As previously noted, the core is preferably made of yieldable material and in addition to the elastic nature of the material of the retaining member, the fingers of the latter are advantageously beveled as indicated, for example, at 18a and 20a in Fig. l, to aid in assembling the parts.

The fully assembled device with a tress of hair held thereby is shown in Figs. 4 and 5, and from the latter, one of the important features of the invention will be apparent. From Fig. 5 it will be seen that, due to the narrow gap 24, it is possible to wind the tress of hair on thecore 1G and to clamp the base portions 26a of the hair of the tress close to the scalp so that the curl produced as a result of the curling operation extends to a point very close to the roots of the hair, or, in other words, close to the scalp of the wearer. This is a highly desirable objective since, while many forms of apparatus and methods used by professional hair dressers are able to achieve this result, the ordinary home hair curling appliance is incapable of effecting a curl close to the scalp of the wearer and is a self-advertisement of a home or amateur operation.

In the embodiment shown in Fig. 1, the ring portion 22 of the retaining member 1% is shown as being of plain cylindrical contour. However, from the standpoint of convenience of manipulation, it will be desirable in some instances to provide the member with a serrated or similarly contoured end surface as indicated at .27 in Fig.

6, the protuberances on the end surfaces facilitatinggrasping of the element by the fingers of the user.

Also, while in the embodiments 'shownin Figs. .1 and 6 the retaining member includes retaining

fingers

18 and 20 which are preferably shorter than

thefingers

14 and 16 between which the gap .24.is formed, this particular configuration need not be adhered to and in Fig. 7 a further form is shown in which in addition to the fingers 14 and i6 defining the gap 24, only a single additional finger 28 is employed.

When in accordance with the principles of the invention a porous substance such as that previously noted is used for a core member, sufiicient ventilation for the required purposes may be obtained with core members in the form of solid cylinders, but within the scope of the invention other forms of core members may be employed, such, for example, as the annular form shown in Figs. 8 and 9 in which the core member 10a is in the form of a cylindrical annulus. In this form of the device, the retaining member 12 may comprise, in addition to the

fingers

14 and 16 between which the gap 24 is defined, retaining fingers and 32 formed to engage the inner wall or bore of the annular core member 10a to retain the member in place. The forms of retaining members shown in Figs. 1, 6 and 7 may be used with an annular core member rather than the form of retaining member embodying fingers engaging the inner wall of the annulus, and it will be equally apparent that the particular configuration of the end portion or collar of the retaining member may, quite independently of the number and arrangement of the fingers, have any desired and/or outer surface contour to facilitate manipulation.

While in all of the embodiments illustrated the end ring portion 22 of the retaining member is split so as to be readily expansible to accommodate itself over a core and a tress of hair wound thereon, and such construction is preferred, it is not essential to the exercise of the invention, since even with a circumferentially continuous end ring, the resilient or yieldable nature of the core member contemplated by the invention in conjunction with the flexibility of the fingers would enable the parts to be assembled in the manner intended in order to carry out the objects of the invention.

From the foregoing it will be apparent that the invention may be carried out with numerous ditferent specific forms and designs of apparatus and it is accordingly to be understood as embracing all forms of article falling within the scope of the appended claims.
