HAIR WINDING DEVICE BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair winding device and more specifically to a device upon which hair can be wound and treated during the performance of a variety of conventional methods for permanently waving hair.

2. Description of the Prior Art Conventionally, cosmetologists when permanently waving hair utilize hair winding rods and end papers to wind the individual shafts of hair into curls prior to treating the hair, Prior art winding rods of a widely used type have a hollow interior and at least one end opening. Such rods also have either several apertures or an elongated slot intermediate the opposite rod ends through which hair treating fluids can be applied to the hair wound upon the rod. Most of these rods have attached members for holding the hair wound upon the rod in wound position during the application of the permanent wave hair treating fluids. However, conventionally, the end papers used with the rods are separate from the rods and consist of disposable, rectangular sheets of sized paper. While sheets of cloth and other materials have also been used, sized end papers comprise substantially all of the end papers commercially used.

Conventionally, the end papers are used by a right-handed person in the following manner. The end paper is held in the left hand in a position to lay on a strand of hair desirably rolled onto a rod. The end paper is then folded beneath this strand so as to position the strand between opposite portions of the end paper and the end paper is moved by the left hand toward the end of the strand of hair until the curled hair ends, commonly called fishhook ends", are straightened and positioned midway between the opposite peripheral boundaries of the end paper. The rod is then placed adjacent to the outer peripheral boundary of the end paper, and the end paper initially, then the strand of hair positioned in the end paper, and then, the exposed portion of the strand of hair is rolled onto the rod by rotating the rod with the right hand in the desired direction of the curl. When the desired strand of hair has been rolled upon the rod, the rod is held in the left hand and the attached hold ing member is secured to the rod by the right hand so as to hold the shaft of hair rolled upon the device in position, With each shaft of hair in this position, the permanent hair waving treating fluids are applied to the hair.

While many such methods are used, one conventional method for applying such fluids is to insert a syringe or like bulbous device full of the desired fluid into an end opening of the rod and to force the liquid into the rod and through the rod aperture and end paper onto the rolled hair. Whether the fluid is applied from the exterior of the rolled hair or from the interior, for example, through apertures in the rod, the fluids must pass through the end paper in order to reach all of the hair rolled upon the rodv After the hair is suitably treated, each shaft of hair is unrolled from the rods and the end papers are thrown away.

A left-handed person utilizing the rod and end papers as above-described performs the same operation using the left hand instead of the right hand and vice versa. However, there are several differences between a hair winding device desired by right-handed and left-handed persons, respectively. First, since the end paper is held in the left hand of a right-handed person and in the right hand ofa left-handed person, when the paper is folded, the fold is preferably at the left for a righthanded person and at the right for a left-handed person. Secondly, since the attached holding member is placed in holding position by the right hand of the right-handed person and the left hand of the left-handed person so as to hold the hair rolled upon the device in position prior to the application of the permanent wave hair treating fluids, the preferred rod for a right-handed person has this member attached to the right end of the device and the preferred rod for a left-handed person has this member attached to the left-hand end of the device. Also, the end opening through which fluids can be forced to treat the hair rolled upon the hair winding device is, conventionally, in the end opposite that to which the holding member is attached,

Other modifications are necessary since other cosmetologists do not fit exactly into the normal right-handed or lefthanded patterns. Thus, individual cosmetologists may prefer, for example, the end paper to be positioned as for a righthanded person and the holding member to be attached to the device as for a left-handed person. It is therefore highly desirable to provide a hair winding device having the versatility such that each cosmetologist can adapt the device to his own liking since the cosmetologists speed in applying a permanent wave to a customer, and thus to some extent his profits, may be determined by how well he can adapt to the device and end paper being used.

It is for this same reason that it is highly desirable to provide an improved hair winding device having an attached and reusable winding pad. Such a device eliminates the need for separate end papers. With a winding pad attached, the ease of handling both the winding pad and the hair winding device is greatly simplified over the conventional method above described in which separate end papers and a conventional rod are used.

When using a conventional rod and separate end paper, the rod can be converted from a right-handed device to a lefthanded device by merely turning the rod end to end. However, as soon as a reusable winding pad is attached to a hair winding device for use as above described, the winding device can no longer be turned end for end to convert the device from a right-handed device to a left-handed device. Further, not only the winding pad but also the holding member which is secured to one end of the winding device must be capable of being removed from the device and changed from a right-handed to a lcft-handed position on the device in order to provide the desired versatility. For these reasons, it is highly desirable to provide an improved hair winding device having an attached and reusable winding pad which has means by which both the winding pad and the holding member of the device can be switched from a left-handed position to a right-handed position. Such a winding device must be provided at a cost to the cosmetologist, i.e., at a retail price, which is substantially the same or lower than his cost of conventional rods and disposa ble end papers to becommercially successful.

SUMMARY OF THE INVENTION In the broader aspects of the invention, there is provided a hair winding device of self-supporting and non-absorbent material. An elongated member is provided to be removably secured to one end of the device relatively permanently and connected to the other end of the device when desired for holding a shaft of hair wound upon the device in wound condition. Also connected to the device is a winding pad of relatively thin sheet material. The winding pad has two portions one of which is connected to the device intermediate the opposite rod ends and adjacent to a boundary of the winding pad. The other portion of the winding pad is not secured to the device and capable of being folded over or under the secured portion and wound upon the device.

It is therefore an object of this invention to provide an improved hair winding device.

Another object of this invention is to provide an improved hair winding device having an attached winding pad which can be more rapidly used in the performance of conventional permanent wave hair treating methods than conventional rods and separate end papers.

Another object of this invention is to provide an improved hair winding device having an attached and reusable winding pad of relatively thin sheet material which is not self-supporting, stretchable or absorbent, but, in contrast, is flexible, porous and resistant to attach from both the conventional hair treating fluids and the temperature of conventional sterilizers.

Yet another object of this invention is to provide an improved hair winding device having an attached winding pad having two portions, one portion being secured to the device and the other portion unsecured so as to be capable of being folded over or under the secured portion and wound upon the device in a manner similar to conventional end papers.

A further object of this invention is to provide an improved hair winding device having an attached winding pad and an attached holding member for holding a shaft of hair wound upon the device in wound position, both of which can be removed from the device and re-attached when desired to change the device from a right-handed device to a left-handed device.

Still further an object of this invention is to provide an improved hair winding device having an attached winding pad and an attached member for holding a shaft of hair wound upon the device in wound position both of which can be removed from the rod and re-attached independently of each other so as to give to the rod the desired versatility to render the device more rapidly usable by each and every cosmetologist performing a conventional permanent hair waving method in his accustomed manner.

The above-mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following description of an embodiment of the invention taken in conjuction with the accompanying drawings, wherein:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, and more specifically to FIGS. 1 through 7, there is shown the improved hair winding device of this invention to generally comprise a rod member (four different embodiments being disclosed herein), a holding member 12, and a winding pad 14.

The first embodiment 10 of the rod member is generally tubular in shape and has a longitudinal axis 11 and opposite ends 16, 18. Both ends 16 and 18 have end openings 20 therein of substantially the same size and shape. End openings 20 communicate with an interior cavity 22; and thus, rod 10 can be accurately termed hollow. (Two different shapes of cavity 22 adjacent to rod ends 16, 18 are disclosed herein; see FIGS. 5 and 15 and FIGS. 8 through 14.) Intermediate the opposite ends 16, 18 and communicating with cavity 22 and an exterior surface 50 there is either one or more apertures or an elongated slot therein. Rod 10 is shown to have a slot 24 which extends longitudinally and in an end-to-end direction of the rod and which terminates at positions 26 and 28 respectively adjacent to but spaced apart from ends 16, 18 of the rod. Rod ends 16, 18 are respectively adapted to removably secure one end of the holding member 12 (three different rod-end embodiments are disclosed herein for this purpose; see FIGS. 1 through 7, FIGS. 13 and 14, and FIGS. 15 and 16) and to removably connect the other end of the member 12 to the rod 10. (Two different rod-end embodiments are disclosed herein for this purpose; see FIGS. 1 through 7 and FIGS. 8 through 14.17 and 18.)

While various embodiments of rod ends are disclosed herein, it should be understood that each rod of this invention is to have its respective ends adapted to removably secure one end of the holding member 12 and to removably connect the other end of the holding member 12. Preferably, both of the ends 16, 18 of the rod are adapted to relatively permanently and removably secure one end of the member 12 to the rod as desired, and each of the ends l6, 18 are also adapted to removably connect the other end of the member 12 so as to allow the rod to be assembled as either a right-handed or left handed rod, as desired. The preferred embodiment of the rod of this invention is also, no matter what specific rod-end structure is used, constructed ofa self-supporting and non-absorbent material which is resistant to attack from both the chemicals of the hair treating fluids conventionally used in permanently waving hair and the temperature of conventional sterilizing devices, for example, a metal or a thermosetting plastic.

Referring now to the winding pad 14, winding pad 14 is shown to be generally a rectangular sheet of relatively thin material. Pad 14, in fact, has opposite longitudinal peripheral boundaries 30, 32 and opposite end peripheral boundaries 34, 36. Pad 14 is divided into two pad portions 38, 40 by a dividing line 42 along which the pad 14 can be folded so as to posi' tion portions 38, 40 one over the other. In the specific embodiment illustrated, portion 38 between the boundaries 30, 32 and 34, 42 is substantially the same size as portion 40 between the boundaries 30, 32 and 36, 42. In addition to the pad 14 intermediate the boundaries 30, 32, 34, 36, portion 38 is provided with a tab 44 adjacent boundary 30 which extends beyond the boundary 30 in a direction transverse to the longitudinal direction of the winding pad 14. Tab 44 also extends in the longitudinal direction of the pad 14 the entire length of the portion 38, and between the pad boundaries 42, 34. Tab 44 provides means by which the pad 14 is connected to the rod, and is the only structure of the pad 14 which tends to render the pad 14 not rectangular in shape. The specific method by which the pad 14 is connected to the rod will be described in detail hereinbelow.

As above-mentioned, the pad 14 is formed of relatively thin sheet material. This material is further highly flexible and not self-supporting in contrast to being rigid or self-supporting. In these respects, pad 14 is similar to cloth or tissue paper. However, the material of pad 14 is also highly porous, non-absorbent and not stretchable or resilient. In these respects, the material of pad 14 is similar to a wire mesh material. Still further, the material of pad 14 is durable in that it is not easily torn, is not brittle or fragile, and is not subject to attack by the conventional hair waving fluids or the temperature of conventional sterilizing apparatus. Lastly, the material of the winding pad 14 preferably has a thickness from about five thousandths of an inch to about fifteen thousandths of an inch. The preferred material of pad 14 is a mesh-like sheet material made from rubber-like materials, for example, urethanes, elastomers, and vinyls. Both woven, non-woven and cast materials can be used.

The above described properties for the material of winding pad 14 relate to the function of the winding pad 14. For example, the flexibility, the thickness, and the fact that the material is not self-supporting allow the winding pad to be easily rolled upon the rod in folded condition without adding substantially to the diametral size of the rod (see FIG. 3). The factthat the material is both porous and non-absorbent allows the permanent wave hair treating fluids to permeate the pad 14 and thoroughly wet the hair located between the opposite portions when rolled upon the rod as will be described in more detail hereinbelow. Because of the lack of absorbency in the material of the pad 14, the pad 14 does not act as a sponge to remove liquid from the hair; but instead, allows substantially all of the fluid to be applied to the hair. The lack of resiliency and the pad being not stretchable substantially reduces the breakage of hair during the winding of the hair onto the rod. If the pad were resilient or stretchable, it could break an appreciable number of strands of hair during the winding process since the strands of hair would be under stress and many of the hair treating liquid fluids used conventionally by cosmetologist render hair strands relatively brittle.

As above-mentioned, the pad 14 can be attached to the rods of this invention in a number of different ways. The manner of attachment illustrated in FIGS. 1 through 7 comprises the provision of a slot 24. FIG. 1 shows one such slot 24; the tab 44 of the winding pad 14 is positioned within another slot 24 disposed diametrically opposite to slot 24 shown. The securance of the tab 44 within the slot 24 can be by adhesive or providing the tab 44 with an enlarged portion positioned within the cavity 22 which will not pass through the slot 24. Any adhesive which is not subject to attack by the permanent hair waving treating fluids and the heat of conventional sterilizers can be used.

Referring now to FIG. 8, a second rod embodiment 10a of the rod of this invention will now be described. The suffix a is used to denote structure unique to the rod embodiment 10a while at the same time to connote interchangeability between the similar structure of the other rods of this invention. Other suffix letters will be used for the same reason hereinbelow. However, identical numbers (without a suffix letter) will be used for identical structure where possible. Otherwise, the use of different reference numerals will indicate distinctly dif ferent structure, for example, structure which is not provided in one of the embodiments, or which is both structurally or functionally distinct from similar structure in another embodiment.

Rod 10a is tubular in shape and has opposite ends 16a, 18a. The rod 10a is divided into two rod portions 46 and 48. In the specific embodiment illustrated, each of the rod portions 46, 48 comprise one half of the rod 10a as if the rod 10a were divided by a plane including the longitudinal axis 11 of the rod 10a. Thus, each of the portions 46, 48 include one half of the exterior surface 50a and one half of each of the ends 16a, 18a. The rod 10a, like the rod 10 is hollow and has end openings 20a in both of the ends 16a, 18a. Extending between the 0pposite ends of the rod are clamping surfaces 52 and 54. These surfaces are positioned such that surface 52 engages the surface 54 when the portions 46, 48 are assembled. The portion 46 is provided, within the interior 22a of the rod 10a, with two male connecting members 56. Both of the members 56 are secured to portion 46 so as to depend substantially radially thereof. Both of the members 56 have enlarged portions 58 adjacent to the distal ends thereof. Secured to the portion 46 between the members 56 are a plurality of teeth 60 which extend from the portion 46 in generally the same direction as the members 56. The members 56 are spaced apart a distance greater than the longitudinal dimension of the tab 44.

Rod portion 48 has secured within the interior 22a two tubular and radially extending members 62. Members 62 are spaced apart a distance substantially identical to the spacing of the members 56; and further, are spaced from the ends 16a, a distance substantially identical as the members 56, respectively. Each member 62 has a detent 64 therein. The members 58 and 62 cooperate to align the portions 46, 48 such that by inserting the members 56 into the members 62, the surfaces 52, 54 are in registry with each other and the portions 46, 48 can be assembled with the opposite ends 16a, 18a and the surface 50a being substantially continuous so as to appear as if the rod 10a were integrally formed as a single piece. Enlarged portions 58 of the members 56 and the detent ridges 54 of the members 62 function to cooperatively and removably secure the rod portions together in an assembled condition by detent action. This detent action between the portions 58 and the ridges 64 also functions to clamp together the surfaces 52,54.

In operation, the separable portions 46, 48 of the rod 100 function to removably secure the pad 14 to the rod 10a so as to allow the rod 10a to be easily converted from a righthanded rod to a left-handed rod as desired. To secure the pad 14, the portions 46,48 of the rod 10a are pulled apart and the tab portion 44 of the pad 14 is inserted between the portions 46, 48. The members 56 and 62 are spaced apart such that the portion 44 can fit therebetween. The teeth 60 are formed so as to either penetrate the portion 44 or to grip the portion 44 when the rod is assembled. The portion 44 is positioned such. that when the portions 46, 48 are re-assembled the teeth will engage the portion 44. Further, the enlarged portions 58 of the members 56 and the detent 64 of the members 62 are positioned such that when the portions 46, 48 are assembled, the clamping surfaces 52, 54 are urged together thereby frictionally holding the tab portion 44 of the pad 14.

Referring now to FIGS. 9 and 10, a third rod embodiment 10b of the rod is illustrated. Rod 10b is also tubular in shape and has an axis 11, a surface 50b, an interior 22b and opposite ends 16b and 18b. Each end 16b, 18b has an end opening 20b therein. Intermediate the opposite ends 16b, 18b, rod 10b has an exterior rod surface 50b. A groove 66 is formed in the exterior surface 50b. Groove 66 has a bottom 68, upstanding sides 70, 72 and opposite ends 74 and 76. Ends 74 and 76 are spaced apart from the rod ends 16b and 18b. The longitudinal and oppositely facing sides 70, 72 and the bottom 68 of the groove 66 extend longitudinally of the rod 10b in an end-toend direction. Groove bottom 68 is not planar, but in contrast, bows inwardly toward the longitudinal axis of the rod.

A member 78 is provided of rigid, self-supporting and resilient material. Member 78 is elongated and has opposite ends 80 and 82. Member 78 has a width dimension and a thickness dimension slightly smaller than the distance between the sides 70, 72 and the depth of the groove 66, respectively. However, the length dimension of the member 78 between the opposite ends 80, 82, is greater than the length dimension of the groove 66 between the opposite ends 74, 76. The bottom 68 of the groove 66 is bowed as above-mentioned; this bow in the bottom 68 is chosen such that the bottom 68 has a length dimension substantially the same as the length dimension of the member 78 between the opposite ends 80, 82.

In operation, the rod 10b and the member 78 function to attach the winding pad 14 to the rod 10b. The attachment ofthe winding pad 14 is achieved in a manner such that the winding pad 14 can be removed from the rod 10b and the rod 10b can be easily converted from a right-handed rod to a left-handed rod, as desired. This removable securance of the winding pad 14 to the rod 10b is achieved by placing the tab 44 of the winding pad 14 over the groove 66. Groove 66 is dimensioned such that the length of the groove 66 is greater than the longitudinal dimension of the tab 44. However, the width of the groove 66 is smaller than the dimension of the tab 44 measured in a direction transverse to the longitudinal direction of the winding pad 14. Subsequent to positioning the tab 44 over the groove 66, end 80 of the member 78 is positioned against end 74 of the groove 66 and end 82 of the member 78 is positioned against the end 76 of the groove 66. In this position, the member 78 bows outwardly of the rod 10b since the ends 74, 76 are closer together than the ends 80, 82. However, the member 78 can then be pushed inwardly toward the rod 10b, and when this is done, the member 78 will resiliently snap into the groove 66 such that the member 78 will be clamped against the groove bottom 68. The member 78 in this position is resiliently held engaged to the groove bottom by the ends 74, 76 of the groove 66 with the tab portion 44 of the winding pad 14 being clamped therebetween. Winding pad 14 can be removed from the rod 10b by merely pulling on the winding pad 14 with sufficient strength to remove the member 78 from the groove 66.

Referring now to the FIGS. 11 and 12, there is shown still another rod embodiment 10c of the rod 10 of this invention. Rod 10c like the other rod embodiments 10, 10a and 10b is hollow and has an interior cavity 220, an axis 11, and opposite ends 160,180 Ends 16c, 180 have end openings 20c therein which communicate with the cavity 22c. Intermediate the opposite ends 16c and 18c, rod 100 has an exterior surface 500. Rod 10c, unlike the other embodiments, is split from end 180 longitudinally of the rod 106 to a position 90 adjacent to end 160 to form a slot 88. Slot 88 defines two bifurcate rod portions 92 and 94. Since the rod 10c is split or divided as if by a plane including the longitudinal axis of the rod, portions 92, 94 are substantially identical and each contain substantially one half of the ends 16c, 18c and one half of the exterior surface 506. Portions 92, 94 are resilient and also have facing and normally spaced-apart clamping surfaces 520, 54c, respectively, which are urged together, in a manner hereinbelow described, to removably secure the winding pad 14 to the rod 100. In these respects, portions 92, 94 are similar to the portions 46, 48 of the rod 10a; however, in contrast to the portions 46, 48 the portions 92 and 94 of the rod 10c are joined adjacent end 160.

In operation, the winding pad portion 44 is positioned between oppositely facing clamping surfaces 52c, 546 of the bifurcated portions 92 and 94. Then, portions 92, 94 adjacent end 180 are urged together to clamp the surfaces 52c, 54c together with the portion 44 therebetween. The arrows 96 indicate the force applied. The specific means of applying the force 96 so as to removably secure the winding pad 14 to the rod 100 will be hereinafter mentioned and described in detail.

Referring to FIGS. 1 through 7, the holding member 12 is shown to be an elongated member having opposite ends 100, 102. Member 12 adjacent each ofthe ends 100, 102 has an enlarged portion 104. These enlarged portions 104 are the means by which member 12 is connected to the opposite ends 16, 18 of the various embodiments of the rod. The member 12 is highly flexible, resilient and stretchable. Preferably, the member 12 is made of rubber or rubber-like materials. Further, the member 12 has a length which is shorter than the longitudinal and end-to-end dimension of the rods. Various methods of connecting the opposite ends 100, 102 of the member 12 to the rod ends 16, 18 will be described hereinbelow. Once again it should be understood that each embodiment of the rod is provided with one of the disclosed means for removably securing end 100 of the member 12 to the rod and one of the various means disclosed for connecting the end 102 to the rod. Each of the rod embodiments 10, 10a and 10!) above disclosed can be provided in accordance with this invention withany of the devices hereinbelow disclosed for connecting the respective ends 100, 102 of the member 12 to the rod. Rod embodiment 10c, however, is more limited in that end 18c must always be the end to which the member 12 is at tached and only the first means disclosed for removably securing the member 12 to the rods can be used. This will become obvious from the description hereinbelow Referring to FIGS 1 through 6, a first embodiment 106 of the means by which end 100 of the member 12 is removably secured to the rod of this invention will now be discribed. Embodiment 106 comprises a cap which has a bottom member 108 and upstanding side walls 110 which are resiliently deformable. Bottom member 108 and side walls 110 define a hollow interior 112 which is diametrically similar in shape and slightly larger in size than ends 16, 18 of the rod with which the cap will be used. Protruding from the walls 110 is a detent ridge 114 which extends circumferentially about the interior surface of the sides 110. All portions of ridge 114 are generally equally spaced from the bottom 108, Adjacent to end 16 of the rod with which the cap 106 is desirably used, there is formed a groove 116 having a size sufficient to receive the detent ridge 114 of the cap 106. This groove 116 is spaced from end 16 of the rod a distance slightly less than the spacing ofthe detent ridge 114 from the bottom 108. This structure allows the cap 106 to be positioned over the end 16 of a rod which is provided with a groove 116 such as that abovedescribed and to be removably secured to the rod by detent action between the detent ridge 114 and the groove 116 (see FIG. 4). The cap 106 in this position, cannot be removed from the rod by pulling on the member 12 which is connected thereto, but. in contrast, can only be removed by forcibly urging the cap 106 from the end 16 of the rod.

Preferably both rod ends 16, 18 of each embodiment with which cap 106 is used is provided with a groove 116 in accordance with the above description. However, rod embodi ment 100 only has end 180 provided with a groove 116 since the cap 106 must always be used with end 180.

End 100 is attached to the cap 106 by means of providing the cap 106 with a slot 120 through which the member 12 can be forcibly urged. Slot 120 has a width which is less than the diameter of the member 12 and of a size such that the enlarged portions 104 of the member 12 cannot be pulled therethrough. Thus by urging the member 12 into the slot 120 and positioning the enlarged portion 104 of the member 12 adjacent end 100 within the interior 112 of the cap 106, end 100 of the member 12 is removably secured to the cap 106.

Referring to FIGS. 13 and 14 a second embodiment of the means for removably securing end 100 of the member 12 to the rod is illustrated. This embodiment comprises a bore 118 having a diameter slightly larger than the portions 104 of the member 12 formed in the rod, preferably adjacent to each of the ends 16, 18. Bores 118 extend transversely of the longitudinal and end-to-end direction of the rod and transversely of the axis 11. Further, bores 118 extend only partially through the walls of the rod as shown in FIG. 14. Extending from the ends 16, 18 and communicating with each of the bores 118 is a slot 120. The member 12 is secured to the rod by positioning the member 12 within the slot 120 and the enlarged portion 104 within the bore 118. In this position, the member 12 is removably secured to the rod end. Only by forcibly urging member 12 through the slot 120 and removing the portion 104 from the bore 118 are the member 12 and the rod disconnected.

Referring now to FIGS. and 16, a third embodiment 122 for removably securing end 100 of the member 12 to a rod is shown. Embodiment 122 comprises a male plug member having a shank portion 124 which is shaped to conform to the interior 22 of the rod adjacent to the end thereof with which the plug 122 is used. In each of the rods, the interior 22 is cylindrical in shape; the shank portion 124 is also cylindrical in shape. lntegrally molded to the shank portion 124 is a base portion 128 which is disc-shaped and has a diameter substantially the same as the rod 10 adjacent to rod ends 16, 18. lntegrally molded to the shank portion 124 is a detent ridge 130. This ridge is parallel to the base 128 and can be similar in size and shape to the detent ridge 114. The shank 124, the base 128 and the detent ridge 130 are all positioned on the same axis. Within the interior 22 of the rod with which the plug is being used, there is formed a groove 132 for receiving the detent 130. This groove can be similar in size and shape to the groove 116 hereinabove mentioned. All portions of the groove 132 are generally equally spaced from the rod ends 16, 18 a distance shorter than the axial distance between the ridge 130 and the base 128 of the plug. This dimensioning provides that when the plug 122 is secured by the detent action of the ridge I and groove 132 to the rod, the base 128 is spaced from the end 16 or 18 a distance 134. This distance 134 is sufficient to allow a person's fingernail or like object to be inserted between the base 128 and the rod for removing theplug 122 from the rod.

Referring now to FIGS. 11 and 12, it is shown that rod 100 adjacent to end 180 is provided with a groove 116s. This groove is formed, as shown, in the opposite rod portions 92, 94. Groove 116a functions to receive the detent ridge 114 of the cap 106. The rod 10c is sized adjacent to end 18c such that when the portions 92, 94 are urged together so as to forcibly engage the surfaces 520, 540, the cap 106 can he slipped over the end 18c and the detent ridge 114 be positioned within the groove 1160. The side walls 110 of the cap 106 apply the force 96 to hold the portions 92, 94 together, and the detent ridge 114 removably secures the cap 106 to the end 18c such that the cap 106 cannot be unintentionally removed.

Referring now to FIG. 19, a fourth embodiment 1360 for removably securing end 100 of the member 12 .to the rod is shown. Embodiment 136a comprises a male plug member having a shank 138 which is shaped to conform to the portion 86 of the interior 22 of the rod adjacent to the end thereof with which the plug 136a is used. Shank 138 differs from the shank portion 124 of the plugs 122 and 122a in that it has a cylindrical portion 140 and a second cylindrical portion 142 separated from the portion 140 by a conical portion 144. Cylindrical portion 140 is substantially the same diametral size as the shank portion 124 of the plug 122; but, the diametral size of the portion 142 is substantially smaller. Conical portion 144 provides a transition between the sizes of the portions 140, 142. Similar to plugs 122 and 122a and shank portions 124 and 1240, respectively, the base 128, the shank portion 138, and each of the shank portions 140 through 144 are all secured on the same axis. lntegrally molded to the shank portion 140 is a detent ridge 130. This ridge is similar in size and shape to the detent ridge 114 and is spaced from the base 128 a distance substantially identical with the distance that the detent ridge 130 of the plug 122 is spaced from its base 128.

Each of the rod embodiments may be formed adjacent to the opposite ends 16, 18 to have an interior portion 86 (FIGS. 15 and 19). Portion 86 has a shape similar to the shank portion 138 of the plug 136. Interior portion 86 has a cylindrical portion 146, a conical portion 148, and a cylindrical portion 150 of smaller diameter than portion 146. However, the axial dimension of the portion 146 is shorter than the portion 140 such that when the plug is positioned therein, the base 128 is spaced from the end of the rod a distance 134 by the engagement of the conical portion 144 with the conical portion 148. Obviously, when using either of plugs 122 or 136a, the shank portion 124 of the plug 122 must be slightly shorter than the shank portion 140 of the plug 136a and the detent ridge 130 'must be appropriately positioned such that the ridge 130 is positioned within the groove 132 prior to engagement between shank portions 124, 144 and surface 148 (see FIG. 15).

Referring now to FIGS. 1 through 7 once again, mention will now be made of the manner by which end 102 of the member 12 is connected to the opposite rod end of the rod embodiment. This connection of the member end 102 to the rod is achieved by either the plug 122a (FIG. 17) or a plug 136. These plugs are similar to but different from the plugs 122 and 136a in that plugs 122a and 136 have no detent ridge 130. Plugs 136 and 136a both have a base 128 and a shank portion 138, and plugs 122 and 122a both have a base 128 and a cylindrical shank portion 124.

In a specific embodiment of each of the plugs 122, 122a, 136, 136a and the cap 106, the tolerances between the shank portions 124 and 138 of the respective plugs and the interiors 22, 86 of the respective rods and the tolerances between the upstanding sides 110 and the exterior of the rods are such that each would fall off the rod if it were not for the detent devices 114,116 and 130, 132 ofthe cap 106 and the plugs 122, 136a, respectively, and the resiliency of the member 12 which holds the plugs 122a, 136 within the interior portions 22, 86. Appreciably tighter or looser tolerances than those which would just allow the plugs and caps to fall from the rods are not preferred.

Also, in a specific embodiment, each of the plugs 122, 122a, 136 and 1360 has an opening 160 therein. Opening 160 is coaxial of the respective plugs and communicates with the interior 22 of the rod with which the plug is used so as to provide an opening in which a syringe or like device can be positioned in order to apply hair treating fluids to the hair rolled upon the devices of this invention as above-described. Further, each of the plugs 122, 122a, 136, 136a are attached to the member 12 by a bore 118 and a slot 120 in the manner above-described.

Bores 118 extend axially of the plug into the bases 128 but are spaced apart from the plug axes and do not extend all the way through the bases 128. Slots extend from the periphery of the bases 128 and between the opposite flat surfaces thereof radially inwardly to the center of the bore 118.

While detent structures are disclosed herein and are abovedescribed. this invention contemplates other detent means; and, the invention of this embodiment should not be limited to the specific detent means illustrated and described.

The improved hair winding device of this invention by having an attached winding pad can be used by cosmetologists to perform conventional permanent hair waving methods more rapidly than with conventional rods and separate end papers. Further, the winding pads above described all are reusable and relatively durable, and further, have all of the preferred physical properties of an end paper. Further, the hair winding device of this invention provides for both the winding pad 14 and the holding device 12 to be removably secured to the device in both a right handed and a left-handed position such that the device can be tailored to the particular preference of the cosmetologist using the device. For these reasons, the device of this invention can be used by cosmetologists without changing his accustomed manner of performing conventional permanent hair waving methods.
