(C1. 132-41) ABSTRACT OF THE DISCLOSURE A hair curling device, having an elongated generally cylindrical hollow outer body with comb teeth protruding therefrom and having improved structural components fr selective protraction and retraction of the comb teeth. The comb teeth are arranged in apertures, extending through the hollow outer body, and the apertures and the comb teeth are parallel With the longitudinal axis of the device.

nuan-n.

This invention generally relates to hair curling devices and more particularly, to hair curling devices which in clude a hollow outer body or tube in combination with hair securing, teeth containing mernbers which are retractable into the hollow outer body.

Numerous devices are known for retaining, over a mandrel, a wound hair lock during the formation or setting of a curl. In the most simple form, such devices typically include a bar 0r mandrel having teeth thereon, and a clamping attachment to retain the curl in place until it is set. In using such devices, considerable difl1culty is experienced in re-moval of the curl from the teeth cf the comb. The curls frequently are disrupted and substantial rnanipulation is required to withdraw the comb without destroying the set cf the curl. More elaborate hair curling devices are also known. These latter devices, nevertheless, are too complicated and expensive for practical use.

The present invention provides a substantial improvement over the type of hair curler in which retractable hair securing means are provided, primarily by inclusion of retractable hair securing bars which retract from or engage hair in a positive and efficient manner and yet is simple in construction such that the curler rnay be economically mass produced.

lt is an object of this invention, therefore, to provide a new and novel hair curling device having teeth disposed on a retractable hair securing bar such that the teeth rnay retract from or engage a lock of hair in position about an outer body tunbe during hair settirrg while providing means for withdrawing the teeth from engagement With the formed curl to per:mit the curler to be readily rernoved from the hair convolutions without distortion of the set.

It is also an object of this invention to provide a hair curling device of simple and inexpensive construction and having a multiple number of hair securing bars provided with teeth which rnay readily be protracted or retracted to facilitate curl formation.

It is another object of this invention to provide a hair curling device having a multiple number of hair securing bars which rnay be simultaneously protracted or retracted in position in a positive and eflicient manner to facilitate curling of hair.

lt is a further object of this invention to provide a hair curling device having a minimum number of separate arts which rnay be readily forrned from inexpensive materials and then assembled With a minimum number of operations.

These and other objects and advantages of the present invention will become more appaient from the following description, taken Wtih the accornpanying drawings in which:

FIG. 1 is a perspective view of a hair curler embodying 3,419019 Patented Dec. 31, 1968 the present invention and illustrating the curler as it rnay appear with the hair securing bars clamped and in protracted position;

FIG. 2 further illustrates the embodirnent of FIG. 1 as it appears from a side elevational view taken in halfsection;

FIG. 3 is a further side elevational view of this embodiment taken in half-section and illustratin*g the assembly as it appears With the clamp removed and the teeth in retracted position;

FIG. 4 is an exploded view of the hair curler of FIG. 1 showing the three principal elements thereof;

FIG. 5 is a side elevational view of the clamp which rnay be employed to retain the hair securing bars in protracted position;

FIG. 6 illustrates an embodiment of the present invention taken as a front elevational view wherein the hair securing bars are formed integral With the outer body tube and in clamped, protracted position;

FIG. 7 is an exploded view of the hair curler of FIG. 6 showing portions of the outer body tube in broken section;

FIGS. 8-9 present opposite end views of the central element and of the outer body tube respectively cf the curler of FIG. 7 as taken in partial section to illustrate the clamp engaging gears;

FIG. 10 is an elevational view of the cam of the central element which engages the hair securing bars;

FIG. 11 illustrates the relative position of the cam and hair securing bar, taken in partial section when the teeth are in protracted position; and

FIG. 12 similarly illustrates the relative position of the cam and hair securing bar when the teeth are in retracted position.

Referring to the drawings in which like numbers represent the same elements in the severa1 views, FIG. 1 shoWs hair curler 20 having outer body tube 22 which is generally cylindrical and provided with ventilation apertures 24 and elongated apertures 26 through which rnay be projected comb teeth 28. Clamp 30 rnay be employed, if desired, to secure the comb teeth in protracted position through elongated apertures 26 by engagement of clamp legs 32 and 34 With notches 36 and 38 disposed around the inner surface of rims 40 and 42 located on either side of the hair curler. The outer surface of rim 42 rnay beserrated to conveniently serve as a handle for rnanipulating the comb teeth and to prevent slipping during use cf the curler. Side ventilation apertures 44 and 46 rnay also be included, if desired, in the hub of Tims 40 and 42 to assure more complete ventilation of air through the curler.

FIG. 2 illustrates hair curler 20 taken in half section with three hair securing bars 48, 50, and 52 shown in protracted position and containing a row of comb teeth 28 thereon. It is recognized that any multiple number of hair securing bars rnay be employed in a hair curler such as from 2 to about 8 depending upon the complexity of the hair curler desired and each hair securing bar rnay contain more than one row of comb teeth either spaced in parallel er at random on each bar. The only requirement for smooth operation of the hair curler during retraction and protraction of the hair securing bars is that the bars be substantially equally disposed when in place about the circumference of outer body tube 22. Each hair securing bar is provided With pivotal links 54 and 56 near each end thereof. Pivotal link 54 located near one end of the bar is integrally connected With Slip ring 58 having an inner retaining wall 60 and a slightly smaller insertable flange Wall 62 which rnay securely engage end plate 64 at a provided, centrally arranged opening to receive the slip ring. In assembling the hair curler, Slip ring 58 is merely inserted into the centrally arranged opening of end plate 64 and once seated, the

slip ring rernains permanently fixed in place. The opening formed within slip ring usefully provides side Ventilation aperture 44.

Opposite pivotal link 54 on bar 48, for exarnple, is pivotal link 56 which is integral With actuator member 66 having rim 42 formed near the outer perirneter f the rnember and side ventilation aperture 46 formed as the hob.

FIG. 3 illustrates hair curler as it may appear in quarter secti0n With clarnp removed. It i: apparent that by rernoving clamp 30 and pulling actuator mernber 66 axially, tension will be applied to pivotal links 54 and 56 such that hair securing bars 48 and 50 Will be retracted or drawn toward the central axis of the cnrler. Link notches 68 are preferably included With pivotal links 54 and 56 near the connection points to provicle and facilitate the pivotal action. In orcler to retain comb teeth 28 in retracted position within outer body tube 22, suitable locking means illustrated as knobs 70 in FIG 3 may be included on actuator member 66 for engagernent With holes 72 provided in outer body tube 22. Other suit able loeking rneans may also be employed in place of knobs 70 and holes 72 if desired.

The prineipal elements forming hair curler 20 are illustrated in FIG. 4 and include outer body tube 22, alternate ernbodirnent clamp 74 further shown in side elevational view in FIG. 5, and central element 75. Except for alternate em-bodiment clarnp 74, the various unique cornbination 0f parts 0f the central element and the outer body tube elements have been previously defined. Clamp 74 includes, in addition to legs 76 and 78 having sligl1tly beveled edges 80 and 82 respectlvely, flange 84, which rnay be either srnooth as illustrated or alternately, embossed, toothed, or provided With hair gripping members now shown, to retain the curvature of a wound curl while the clamp is in place during the curl setting period. Flange 84 eliminates any sharp depressions which may otherwise appear in the formed curl when a more simple configuration is employed for the clarnp such as one formed from a fiat plate.

FIGS. 6-7 illustrate an ernbo liment eurler of the present invention wherein the hair securing bars are formed integral With the outer body tube. With specific reference to FIG. 6, hair curler 86 is shown With elarnp 74 in platze and comb teeth 88 having varying heights as described hereinafter in protracted posltion 0n hair securing bars 90 and 92. Hair securing bars 90 and 92 are formed by removing longitudinal strips 94 and 96 from the outer body tube 98. These removed strips provide ventilation apertures and may be supplernented by additional ventilation aperture 100.

In FIG. 7, the three principal elements of hair curler 86 are shown in more detail and included clamp 74, outer body tube 98, provided With c:lamp engaging notches 99 and central element 102. Central element 102 ineludes hollow shaft 104 Which supports cam 106 at one end and serrated rim 108 at the other end. Rim 108 may be provided With a suitable retaining means, not shown, to secure the rim in operating relationship With the outer body tube 98. Clamp engaging notches 115 rnay also be provided about the inner surface of rim 108 as shown in partial section in FIG. 8. Side ventilation apertures 117 in FIG. 8 and 118 in FIG. 9 rnay also be pr0- vided, if desired.

Cam 106, shown further in FIG. 10, has centrally arranged cut-out 110 for adaptation on hollow shaft 104 and eccentric cam apertures 112 each of Which individually engages hair securing bar 90 which may ride in depression 111 as Cam 106 rotates. Engagement of cam 106 With hair securing bar 90 rnay be more clearly seen in FIGS. 11 and 12 wherein angle bracket 114 is shown connected to the base of hair securing bar 90 and provided With pin 116 which engages eccentric aperture 112 01 cam 106. Bracket 114 may be f0rrned either separate or integral With bar 90 as desired In operation, comb teeth 88 of varying lengths are rnaintained in protracted position when pin 116 is at a position in eccentric aperture 112 which is the maximum distance frorn the axis of rotation. By rotating rim 108 and resultantly, cam 106, pin 116 travels within eccentric aperture 112 to a mininiurn distance from the axis of rotation of the carn and thereby withdraws the hair securing bar into retracted position. It is apparent that because of the varying lengths of the eomb teeth 88 on a bowed hair securing bar, the edges of the comb teeth 88 appear below the surface of outer body tube 98 of the hair curler.

In Operation; the comb teeth of the hair cnrler of the present invention are first manipulated to protracted position in order t0 receive a tress of hair wound about the outer body tube by rotating the curler about its longitudinal axis. When the desired amount of hair is wound on the curler, the clamp may be inserted in position on the curler to secure the curler in place during the setting of the hair. After the curl has been set, the clarnp is removed and the comb teeth manipulated t0 retracted osition whereupon the curler rnay simply be withdrawn endwi:e from the finished curl without distortion.

With respect to construction of the various elements of the present hair curler, it Will be recognized that the eparate elements may be economically molded or extruded frorn thermoplastic organic resinous material such as polyethylene, polypropylene, nylon, or the like. In order to reduce friction and to facilitate manipulation, certain of the working parts may be formed of metal or lubrieant containing plastic materials as desirecl.
