BACKGROUND OF THE INVENTION The present invention relates to an improved hair roller and particularly one with which hair curl size can be controlled to give it a varying pitch and corresponding tension between the root end and tip end. The hair roller is easily adjusted for producing different curl effects and also possesses certain constructional attributes designed to accelerate the drying of the rolled bundle of hair, thereby reducing the amount of time required to style the users hair.

In styling women's hair and in particular in applying a set thereto, it is customary to roll dampened hair in bundles and dry it in the rolled condition in order to impart a curl to the hair. Depending upon the desired style or setting to be created, curls of different sizes and of varying diameters must be formed. After the hair is dried and the rollers removed, the stylist or user works with the curled hair to produce the intended style and effect. The success of the styling depends to a large measure on the manner in which the tip ends of the hair have been wound both as to the pitch of winding and tension in the tip end as compared with the hair near the root end. For example, in most instances, the tip end winding or curl should be of small pitch giving a tight more tense curl. On the other hand, the hair near the root end should have a large loose curl. In this manner the hair hangs better and the critical tip end better and longer holds its set. For example, if effecting a Page Boy" style the hair should be set so that the tip ends of the hair should be open and loose. With prior art hair roller devices, it is very difi'icult to produce the foregoing condition in the hair. This is because with prior art rollers regardless of the roller diameter it is impossible to provide a marked difference between the diameter of the hair winding immediate the roller body which is the tip ends of the hair and the diamcter of the hair at the outside of the wound bundle which is the root end of the hair. Thus the full length of hair from root to tip end is wound at generally uniform pitch and consequently when the hair is dried, substantially uniform tension is produced therein. Uniform tension in the hair causes it to lay curled up higher at the side of the head than the style requires and consequently styling procedures to set the hair tip ends down at the proper level must be resorted to which procedures have the effect of reducing the tightness of curl at the tip end. If it is sought to increase the tightness of curl at the tip end by reducing the roller diameter this only compounds the problem. On the other hand use of larger diameter rollers contribute nothing either since while their use is compatible with the forming of a large pitch of curl at the root end of the hair, the same pitch of curl is produced at the tip end and lacks the necessary tightness or tension to hold the tip end styled for a very long period oftime.

Also in using prior art roller devices, since there is no comparative differential in the size of hair winding first and last wound thereon, the dampened hair lays on the roller in a dense bundle making it difficult for air to penetrate the mass to dry it evenly and completely in a given period oftime.

SUMMARY OF THE INVENTION The present invention is concerned with an improved form of hair roller which comprises a wrapping sheet on which the user's hair can be received and wound in a number of windings. The wrapping sheet may be used in conjunction with a core member shaped into a generally cylindrical body of any one of a number of predetermined diameters. Both the core and the wrapping strip are liberally provided with openings extending therethrough so as to provide air access openings in the roller when it is used for its intended purpose. According to the invention, the hair roller is used by gathering the hair to be curled into a bundle and receiving the tip end ofthe bundle on the core. The stylist or home user then proceeds to wind the bundle intermediate the core and the wrapping strip in a number of successive convolutions to roll the hair to the extent necessary for the intended style of the hair to be effected, an important feature of the present invention being that the wrapping strip is provided on one side thcreofwith projections outstanding from the surface therefrom which function to engage against the roller core and any already convolute winding in which the wrapping strip has been formed to space each convolution of the wrapping strip from the others. In this manner the successive windings of the hair are wound at an increasing pitch from the tip end toward the root end and are held out of contact with the others providing aspace between the successive windings to permit axial as well as radial entry of air to promote drying of the hair.

According to the invention, the roller may be made as a unitary device comprised of a relatively flat section rollable into the form of a cylindrical core and having fastening means for maintaining it in that condition, and a wrapping stripjoined to the Hat section. In the alternative, the core member can be provided as a separate preformed cylindrical body with a slot formed along the length thereof suitable for receiving therein an end portion of the wrapping strip. The wrapping strip used in conjunction with the core can be either a strip member formed from a resilient material thereby having certain selfwinding properties, or it may have incorporated therein separate winding means, or the wrapping strip may he a normally relatively flat component, employing no self or separate winding means therein at all. In any event, and in each con structional form thereof, the wrapping strip is provided with projecting means in the same manner above described.

The invention accordingly comprises the features of construction, combination of elements, and arrangements of parts which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

Throughout the following description like reference numerals are used to denote like parts in the drawings.

DESCRlPTlON OF THE PREFERRED EMBODlMENTS The hair roller of the present invention is of relatively sim ple but yet effective construction, easily and inexpensively can be manufactured and is adapted readily for use both in the professional hair styling establishment and the home. it can be employed by the stylist or home user with facility since its construction is such as to allow readily for rolling the hair rapidly and accurately in the desired curl forms. Moreover, its use makes possible a high degree of control of curl size particularly at the hair adjacent the tip end. Further it produces in use a well defined overall curl effect and eliminates droop at the curl ends, giving good body to the curl. The hair roller can be made in various embodiments and with the modifications in construction as will appear.

The form of hair roller 10 shown in FIGS. 1-4 is an elongated normally essentially flat structure which desirably is made as a one-piece construction and is provided at one end with a relatively wide, generally flat segment 12 which can be shaped in the form of a cylinder or core by rolling the segment upon itself. Suitable locking means in the form of interengaging apertures 14 and bosses 16 are embodied in segment 12 and provide that when so interengaged, the segment 12 will remain in the rolled condition shown in FIG. 3. As can be discerned, the cylindrical core into which segment i2 is formed can be of varied diameter depending on which transversely arranged row of apertures is selected for engagement with the bosses to. As will be understood from further description given herein, the diameter of the cylindrical core is varied depending upon the particular tightness ofcurl to be given the tip end of the hair. However, the use of the core to provide an initial winding surface on which the first convolution of hair (the tip end) can be wound is itself an essential requirement. The apertures 14 also provide ventilation openings for admitting air readily to the hair wound with the roller for the purpose of speeding up the drying of the hair. The hair roller 10 also includes as another part thereof, a wrapping strip segment l8 which can he made of somewhat lesser thickness than the segment 12 and which also is pro vided with a number of ventilation apertures as at 20. Moreover, the wrapping strip segment 18 is provided with a number of rows of projections 22 which function when the wrapping strip is wound about the cylindrical core with hair sandwiched between it and the core to space each convolution of hair from the others to thereby provide as shown in FIG. 4 positive an opening between the successive convolutions for admission of an axial flow of air for drying the hair. However, of more importance the projections 22 function to produce a larger comparative curl diameter at the root end of the hair than at the tip end thereby allowing for the tip end to assume a tightness of curl whereas the hair near the root end is relative ly untensed giving the curl good body without any sign of droopiness.

in the form of hair roller shown in FIGS. i il both the seg ment l2 and the wrapping strip 18 are made from a material which is susceptible of being wound into cylindrical or com volute form' It is also possible for both segment 12 and wrapping strip 18 to be made of a material that would give them certain self-winding properties. in using the hair roller 10, the core segment 12 first is formed or shaped into a cylindrical core as shown in FIG. 3, the diameter of the cylinder being one selected in accordance with the particular tightness of curl and tension to be imparted to the tip and of the hair.

The segment 12 is then secured in shaped condition by engaging the bosses 16 in the apertures M which are associated with the desired core diameter. A bundle 24 or group of strands of hair desirably first dampened in the usual manner is then gathered together in the manner shown in FIG. 3 and the tip end thereof received on the cylindrical core with the tips of the hair being positioned adjacent the junction of the wrapping strip 18 with the core. The user then proceeds to wind the hair into a series of convolute windings by rotating the core windingly upwardly against the wrapping strip producing the wound structure shown in FIG. 4 with the successive windings of the hair being spaced one from the others by reason of the engagement of the projections 22 with the surface of the core and the hair pressed thereagainst in the manner shown in FIG. 4. Thus, it will be understood that the first complete winding of the core holds the critical tip end of the hair at the desired curl diameter. Successive windings of both hair and roller of course will occur at an increasing pitch because of the presence of the wrapping sheet of the projections 22. The final winding of the root end ofthe hair as shown in PK). 41 will have a much larger comparative diameter than the tip end or core winding of the hair to give little or no tension to the root end hair. The rolled up bundle of hair may then be secured against unrolling by utilizing a hair pin or like clamping element to hold it as shown in FIG. 4. Clamping means also can be providedon the hair roller itself. For example, an elastic cord 26 can then be secured to one side of the roller body as at 28. The cord 26 can then be stretched through the center of the core and back across the outside of the rolled structure to allow the enlarged head 32 at the end of the cord to be engaged or secured in one of the lateral slits 34 formed along the margins of segment 12. Thus, the cord 26 functions as an elastic clamping means. Because of the spacing between successive convolutions of hair provided by projections 22, drying air is better able to gain access axially to the mass of hair and more rapid drying is achieved than is possible when using prior art roller devices. After the hair is dry, the clamping means is released and the rolled bundle of hair is unwound. The curls formed in the bundle are then styled by the hairstylist according to the intended hair styling effect to be produced.

In accordance with the present invention the hair roller may he provided with the core member and wrapping sheet parts thereof formed as separate elements in the manner shown in FIG. 5. in this form, the hair roller 50 includes a core 52 com prised of an elongated cylindrical shaped body preferably made of a resilient material such as plastic and provided with an elongated slot as at 54 wherein can be received an end portion-of the separate resilient wrapping sheet 56. in the manner of the hair roller device it) described earlier, the wrapping sheet 56 is provided with suitable ventilation apertures 58 and projections 60 adjacent the side margin thereof, the projections being located at the underside of the wrapping sheet in FlG. S. Wrapping sheet 58 can be formed of a resilient material possessing self-winding properties, or it can have means embodied therein which impart selt winding properties as for ex ample spring steel strips desirably located along the margins of the sheet. Also the sheet 58 can be an ordinary normally flat sheet having no self==winding properties at all. Core component 52 also is provided with ventilation apertures 53. In use, the hair roller 50 is used in the same manner previously described for hair roller 10 particularly with respect to the function of the projections 60 for spacing the successive windings of the hair to accelerate drying. it will be understood of course that core member 52 most usually will be provided with a predetermined diameter. Thus, if it is desired to alter the size of the curl and particularly the tip end curl diameter which can be made with the hair roller 50 a different sized core member such as the core 62 shown in FIG. 6 is used for producing a larger curl. Thus, by exchanging core members. various size curls can be produced with the same wrapping sheet.

It will be seen then that the hair roller device of the present invention is a notable advance over the construction of such devices as are known in the art particularly in that it makes it possible to more accurately control curl size and more adequately produces proper tip end curl diameter and tension by reason of the utilization of a core member in cooperation with a wrapping sheet as previously described. The roller of the present invention is particularly useful for making a pickup curl in the users hair in that the user need merely spray the hair and then roll same on the roller device. Because of the spacing of the successive windings provided by the roller, the hair will dry in a very short time. But more important, the pickup curl will have good body since the tip end of the hair can be wound with the necessary tightness without producing any undue tension of the hair at the root end which would tend to affect the manner in which the entire curl hangs.

It will thus be seen that the objects set forth above among those made apparent from the foregoing description, are efficiently attained and, since certain changes in the roller device construction set forth above, may be made without departing from its scope, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
