A heating apparatus (111) includes a telescopic enclosure (112) having a heating chamber (124) and a heating element (126). The enclosure (112) is movable between an extended condition in which its chamber (124) has a larger volume for containing a larger number of rollers (10) and a contracted condition in which its chamber (124) has a smaller volume for containing a smaller number of rollers (10).

Description: Description ENHANCED HAIR SETTING ROLLERS AND HAIR ROLLER HEATING APPARATUS Technical Field The present invention generally relates to hair styling and, more particularly, is concerned with hair setting rollers having enhanced styling features and with hair roller heating apparatus having a telescopic heating chamber enclosure with holding capacity variable between expanded and contracted volume sizes. Background Art A long-established practice of hair dressers and others is to use hair setting rollers to form waves and/or curls in a person's hair in order to achieve the hair style desired by the person. Various designs of hair setting rollers have been used for this purpose. Representative examples of prior art designs are disclosed in U.S. Pat. No. 3,916,919 to Giordano, U.S. Pat. Nos. 4,526,184, 4,603,706 and 4,627,452 to Caruso, and U.S. Pat. No. 4,974,613 to Ho. A common feature of these prior art hair roller designs is an elongated main body, such as a cylinder or tube, about which hair is rolled and then secured in order to remain wrapped thereon for a desired period of time to allow the hair to set in its wrapped or curled condition. These prior art hair rollers additionally provide a variety of other features which are intended to function in conjunction with the main body to attain optimum hair styling results. For example, the hair roller of U.S. Pat. No. 3,916,919 combines with its main body a hair holding clip in the form of a pair of resilient fingers or a bent rod, a first rubber band extending through the body and attached to the clip, and a second rubber band extendable longitudinally around the body to retain various parts of the hair roller assembled together and to serve as a preliminary holder of hair against the body. After hair is rolled about the body the firεt rubber band attached to the clip can be stretched to permit placement and retention of the clip over an edge of the body so as to hold the rolled hair about the body. The second rubber band is retained about the body by passing across recesses formed by a crenelled edge on one end of the body. The hair rollers of U.S. Pat. Nos. 4,526,184, 4,603,706 and 4,627,452 combine with their main bodies either external projections formed between longitudinal slots in the body to make intimate contact with the hair, arcuate fingers or teeth formed along side edges of the longitudinal slots in the body to catch and comb hair wrapped around the body, or a sleeve of a porous foam material surrounding the body. The hair roller also can have either a separate semi-cylindrical shield with which to handle the roller and to partially surround and retain the wrapped hair on the main body, or a separate or attached hair clip applied over the edge of the main body to embrace a portion of the wrapped hair and retain it thereon. The hair roller of U.S. Pat. No. 4,974,613 combines with its main body a number of molded-in helically contoured grooves for facilitating winding of hair around the body by providing ridges that grip the hair. The hair roller also has a U-shaped hair clipping device pivotally attached to one end of the body and having a spherical tip which snaps into a groove molded in the opposite end of the body for securing the hair wound around the helical contours on the body. However, some of the aforementioned features of these prior art hair rollers would appear in practice to create drawback in terms of decreasing the ease with which the hair rollers can be used and of increasing the complexity and thus the cost of the hair rollers. As a result, these prior art hair rollers fail to provide an optimum combination of features which would greatly enhance and facilitate the ability of hair dressers and others to easily and quickly manipulate the hair rollers so as to wrap and set a person's hair in a manner which would minimize the amount of handling of and contact with the hair and thereby maximize the likelihood of achievement of the desired hair styling results. Consequently, a need still exists for improvements in the design of hair rollers so as to overcome the aforementioned drawbacks of the prior art hair rollers without introducing new drawbacks in their place. Additionally, typically hair setting rollers are heated prior to placement in the person's hair. Often, a combination of both larger and smaller hair rollers are employed to achieve a hair style ranging from loose waves to tight curls. It is desirable to heat each of the hair rollers simultaneously and evenly. Depending on the person's hair and the hair style desired, it is sometimes preferable to be able heat different numbers and sizes of the hair setting rollers. Devices exist that are designed to heat a plurality of hair rollers simultaneously and evenly. An example of one such device is disclosed in U.S. Pat. No. 4,572,221 to Barradas. The Barradas patent discloses a carrying case having a plurality of heating posts within the case. Inside each post is a wire heating element. Hair setting rollers are placed over the posts and the wire heating elements heat the posts thereby heating the rollers to a desired temperature. While the carrying case disclosed in the Barradas patent may heat hair setting rollers satisfactorily, a significant drawback of the case is its limited versatility in holding and evenly heating different numbers and sizes of hair setting rollers. Consequently, an additional need still exists for an apparatus that heats different numbers and sizes of hair setting rollers simultaneously and evenly. Disclosure of Invention The present invention provides hair setting rollers which satisfy the aforementioned needs by incorporating enhanced hair rolling and setting features. The hair rollers of the present invention are user-friendly in terms of ease of manipulation for quickly winding or rolling and thus setting a person's hair to achieved the desired hair styling results. Accordingly, the present invention is directed to a hair roller which compriseε: (a) an elongated body having an annular cross-sectional εhape around which hair can be wound between a pair of opposite ends of the body for styling a person's hair; (b) a hair clip having a hair-engagable blade portion disposed longitudinally along and overlying an exterior side portion of the body and of curved cross-sectional shape conforming to the annular cross-sectional shape of the body; and (c) means for mounting hair clip to the body for undergoing pivotal movement relative to the body along an arcuate path between a closed position adjacent to the exterior side portion of the body and an opened position angularly displaced from the exterior side portion of the body such that a portion of the hair is retained between the blade portion of the hair clip and the exterior side portion of the body when the hair clip is at the closed position and is released from between the blade portion of the hair clip and the exterior side portion of the body when the hair clip is pivotally moved toward the opened position. The hair clip further has a lever portion attached to and extending away from at least one of a pair of opposite ends of the blade portion for engagement by a finger of a user to cause pivotal movement of the hair clip from the closed position to the opened position. The exterior side portion of the body of the hair roller which underlies the blade portion of the hair clip can be inwardly offset from the remainder of the body which permits the blade portion to overlie and be seated on the inwardly offset exterior side portion substantially within an exterior annular profile of the body. The body defines an interior chamber and has a plurality of spaced apart openings, such as holes or slots, defined through the body for providing communication from the interior chamber to the hair wound around the body. The hair roller also comprises an elastic anchoring element made of a stretchible material longitudinally extendable along the body between the opposite ends thereof so as to extend over and thereby anchor thereon the hair wound about the body. The hair roller further comprises a heat retaining member disposed in an interior chamber of the body and adapted to receive heating producing energy from an external source through one end of the body and to retain the heat so produced by the energy for later release to the hair wound around the body during a period of use of the roller. The present invention also provides a hair roller heating apparatus designed to satisfy the aforementioned needs by being adapted for holding and heating different numbers and εizes of hair rollers in a heating chamber encloεure with telescopic parts for changing the holding capacity of the heating chamber between extended and contracted volume sizes. Accordingly, the present invention alεo is directed to the roller heating apparatus which comprises: (a) a telescopic enclosure open at its top and defining a heating chamber therein, the encloεure being convertable between extended and contracted conditions; (b) means for generating heat within the heating chamber; and (c) means in the form of a roller support assembly disposed within the telescopic enclosure for supporting a plurality of hair setting rollers within the heating chamber when the enclosure is dispoεed at each of the extended and contracted conditionε thereof. The teleεcopic enclosure is comprised of a lower housing body having a lower base for receiving and holding a quantity of water therein and an upper annular sidewall that extends upward from the lower base and defines an open upper end of the lower housing body, and an upper housing extension mounted through the open upper end of the lower housing body for undergoing telescopic movement along the upper sidewall toward and way from the lower base. Together, the lower housing body and the upper housing extension define the heating chamber and are telescopic relative to one another between the extended and contracted conditons for changing the holding capacity of the heating chamber. When in the extended condition, the upper housing extension and the lower housing body provide the heating chamber with a first volume for holding hair setting rollers of a first number and/or size. When in the contracted condition, the upper housing extension and the lower housing body provide the heating chamber with a second volume smaller than the first volume for holding hair setting rollers of a second number and/or size smaller than the first number and/or size. The hair roller heating apparatus further includes a removable lid for closing the open top of the upper housing extension, and a water level viewing window structure recessed in the upper sidewall of the lower housing body. The heating means is disposed within the lower base of the lower housing body to generate steam from the water placed therein. The roller support assembly includes an annular bottom platform, a first plurality of heat transmission rods supported upright on the platform, and a second plurality of heat transmission rods that are smaller in diameter than the first rods and are teleεcopically inεerted into the firεt rods. The second rods are telescopically moveable between lowered and raised positions relative to the first rods to accommodate placement of the telescopic enclosure at its contracted and extended conditions. The firεt rodε εupport a first layer of larger diameter hair setting rollers within the heating chamber. When in their raised positions, the second rods support an additional layer of smaller diameter hair setting rollers within the heating chamber above the first layer of larger diameter hair setting rollerε.

DETAILED DESCRIPTION OF THE INVENTION Best Mode for Carrying Out the Invention Referring to the drawings, and particularly to Figs. 1, 3A, 5A and 6A, there is illuεtrated a hair roller of the present invention, generally designated 10, for use in hair styling. The hair roller 10 has enhanced hair rolling and setting features, as described hereinafter, which are user-friendly in terms of ease of manipulation for quickly winding or rolling and thus setting a person's hair to achieved the desired hair styling results. The hair roller 10 is adapted to be employed with and heated by a suitable heating apparatus, such as the one of the present invention described below. Basically, the hair roller 10 includes an elongated body 12, a hair clip 14 pivotally mounted at one end of the body 12, and an elastic anchoring element 16 which preferably, although not necessarily, is attached at the other end of the body 12. Also, the hair roller 10 preferably, although not necessarily, has a porous outer sleeve 18 preferably made of a flexible spongy foam-like material. The outer sleeve 18 surroundε the body 12 and extendε between the oppoεite ends thereof. More particularly, the elongated body 12 of the hair roller 10 is preferably hollow and includes an elongated tubular sidewall 20, preferably cylindrical in shape, and a pair of annular rims 22, 24 attached to respective opposite ends of the tubular sidewall 20. The annular rims 22, 24 have outside diameters greater than the outside diameter of the tubular sidewall 20 such that an exterior cylindrical surface 20A of the tubular sidewall 20 iε receεεed inwardly from exterior annular surfaces 22A, 22B of the annular rims 22, 24. As seen in Figs. 2 and 2A, the porous outer sleeve 18 is confined in the annular space extending between the annular rims 22, 24 and is seated about the exterior cylindrical surface 20A of the tubular εidewall 20 and extendε between the annular rimε 22, 24. The tubular sidewall 20 is thus adapted for having hair wound or rolled around it (and thus around the outer sleeve 18 surrounding and overlying the sidewall 20) for setting and thus styling a person's hair. The elongated body 12 of the hair roller 10 also preferably includes respective opposite end walls 26, 28 connected to the oppoεite annular rimε 22, 24 at the opposite ends of the body 12. Further, the tubular sidewall 20 and opposite end walls 26, 28 of the elongated body 12 define an interior chamber 30 while the tubular sidewall 20 haε a plurality of spaced apart openingε 32 defined therethrough which provide flow communication of a heated medium, εuch as air or steam, and liquids and the like from the interior chamber 30 to the porous outer εleeve 18 and thereby to hair wound around the outer sleeve 18 and tubular sidewall 20. At least one of the opposite end walls 26, 28 of the body 12 haε an aperture 34 formed therein through which can be inεerted a εuitable element (not εhown) into the interior chamber 30, εuch aε provided by the heating apparatuε of the cross-referenced application, in order to supply the heated medium into the interior chamber. The other opposite end wall 26, 28 can be closed. Referring to Figs. 3A to 3E, there are illustrate different configurations of the openings 32. Fig. 3A (and also Figs. 1 and 5A-5D) depict a plurality of circumferentially εpaced and longitudinal extending substantially full-length slotε 36 formed through the εidewall 20 which have generally rectangular εhapes. Fig. 3B depictε a plurality of helical εlotε 38 formed through the εidewall 20 and εpaced from one another along a longitudinal axiε of the elongated body 12. Fig. 3C depictε a plurality of partial-length εlotε 40 formed through the sidewall 20 and being of generally rectangular shape and aligned and εpaced apart in axial columnε and circumferential rows and being much shorter in length than, and thus of partial-length compared to, the full-length slotε 36. Fig. 3D depictε a plurality of εlotε 42 similar to those of Fig. 3C except that the slots 42 in every other axial row are aligned with one another and axially offset relative to the slots 42 in adjacent axial rows. Fig. 3E depicts a plurality of round holes 44 formed through the sidewall 20 and being aligned and spaced apart in axial columns and circumferential rows. Other configurations of the openings 32 are posεible within the purview of the present invention. Also, as seen in Figs. 10-12, the round holes 44 through the sidewall 20 can be overlaid with a variety of raised symbols, such as in the form of stars 41, formed on the exterior surface 20A of the sidewall 20. The tubular sidewall 20 of the body 12 alεo can have a plurality of elongated raised rib or ridge elements 43 formed on the exterior surface 20A of the sidewall 20 and protruding outwardly therefrom and extending in a helical direction thereabout and being spaced apart from one another in an axial direction along the sidewall 20. The helical ridge elements 43 are interrupted and absent from the exterior side portion of the sidewall 20 underlying the blade portion 50 of the hair clip 14. Furthermore, as seen in Fig. 9, the hair roller 10 can have a metallic sleeve 45 installed within the tubular sidewall 20 for improving conduction of heat to the hair wound around the tubular sidewall 20. The sleeve 45 preferably has a cylindrical shape and is of a size adapted to insert and snugly fit within the interior chamber 30 of the body 12. Referring now to Figs. 1, 2, 3A, 5A-5D, 6A, 6B, 7, 10 and 11, there is illuεtrated the hair clip 14 of the hair roller 10 being mounted to one end of the elongated body 12 by a mounting means 46 for undergoing pivotal movement along an arcuate path P (see Figs. 5A-5D and 9) between closed and opened positionε relative to the body 12, and alεo being biaεed to move from the opened position to the closed position by biasing means 48. The closed and opened positions of the hair clip 14 are shown respectively in solid and dashed line forms in both Figs. 5 and 9. Preferably, the hair clip 14 includes a hair- engagable blade portion 50 and at leaεt one lever portion 52. The blade portion 50 of the hair clip 14 iε disposed along and overlying an exterior side portion of the tubular sidewall 20 of the body 12. As seen in Figs. 6A and 6B, the blade portion 50 has an arcuate or curved croεε-εectional εhape conforming to the annular croεs-sectional shape of the tubular sidewall 20 of the body 12. Preferably, the annular cross-sectional shape of the tubular sidewall 20 is that of a cylinder. The arcuate or curved shape of the blade portion 50 is that of an arc falling within a range of from 60° to 120°, and preferably has an approximately 90° or a quarter cylindrical shape, substantially conforming to the 360° cylindrical shape of the tubular sidewall 20 of the body 12. In the closed position of the hair clip 14, the blade portion 50 extends closely along and adjacent to the tubular sidewall 20 of the body 12 substantially the entire distance between the annular rims 22, 24 at the opposite ends of the body 12 such that a portion of the hair is retained between the blade portion 50 and the tubular sidewall 20 of the body 12. In the opened position of the hair clip 14, the blade portion 50 is angularly displaced from the tubular sidewall 20 of the body 12 such that the hair portion is released from between the blade portion 50 of the hair clip 14 and the tubular sidewall 20 of the body 12. Alternatively, as shown in Fig. 9, the blade portion 50 of the hair clip 14 can be provided to extend along the exterior side portion of the tubular sidewall 20 of the body 12 only about half of the diεtance between oppoεite annular rimε 22, 24 at the oppoεite endε of the body 12. Alεo, alternatively, aε shown in Fig. 17 the elongated body 12 can have an hourglasε εhape wherein the diameter of the body 12 decreases from the outer ends to the middle thereof. The blade portion of the hair clip (not shown) would have a curved shape both longitudinally and cross- sectionally that conforms to that of the exterior contour of the body 12 of the hair roller 10. Also, referring to Fig. 7, the blade portion 50 of the hair clip 14 has an interior εurface 50A facing toward the exterior side portion of the tubular sidewall 20 of the hair roller body 12 and means thereon in the form of a plurality of teeth 54 formed on and extending outwardly from the interior surface 50A of the blade portion 50. When the hair clip 14 is in itε closed position, the teeth 54 interengage the portion of the hair being retained between the blade portion 50 and the tubular sidewall 20 of the body 12 so as to enhance the ability of the hair clip 14 to grip and retain that portion of the hair aε the body 12 is then rolled relative to the hair to wind the hair about the tubular sidewall 50. Aε can readily seen in Fig. 7, the teeth 54 are spaced apart from one another in the longitudinal direction of the blade portion 50 of the hair clip 14 extending between opposite ends of the blade portion. The blade portion 50 of the hair clip also has at least one and preferably a pair of εlots 55 defined through the blade portion extending longitudinally between the opposite ends of the blade portion 50. The slots 55 permit passage of liquids and heated medium through the blade portion 50 of the hair clip 14. The lever portion 52 of the hair clip 14 is provided to make it convenient for a user to grip the hair clip 14 with his or her fingers and actuate the hair clip by applying sufficient force thereto to cause hair clip 14 to pivot from its closed to opened position against the force of the biasing means 48 which biases the hair clip 14 to move toward its closed position. As seen in Figs. 1, 2, 3A, 5A-5D, 7 and 9, the lever portion 52 is provided on at least one end of the hair clip 14 and optionally can be provided on both ends thereof, as shown in Fig. 5D. Furthermore, the lever portion 52 can be provided in various orientations relative to the blade portion 50 of the hair clip 14. For example, as shown in Figs. 1, 2, 3A, 5A, 5D, 7 and 9, the lever portion 52 can have a slighly upward curved shape and more so curved as shown in Fig. 5B. On the other hand, the lever portion 52 can have a downward turned shaped as shown in Fig. 5C. Referring now to Figs. 1, 2, 3A-3E, 5A-5D, 6A, 6B, 7 and 9-11, the mounting means 44 of the hair roller 10 is provided to mount the hair clip 14 adjacent one end of its blade portion 50 to the elongated body 12 at the one annular rim 22 thereof. The hair clip 14 is so mounted to undergo pivotal movement relative to the tubular sidewall 20 along the arcuate path P between the closed position adjacent to the exterior side portion of the sidewall 20 and the opened position angularly displaced from the exterior side portion of the sidewall 20. More particularly, preferably the mounting means 44 includes a pair of spaced apart tabs 56 attached on the exterior annular surface 22A of the one annular rim 22 and extending outwardly therefrom, and a cylindrical pin 58 extending between and mounted to the tabs 56 and rotatably or pivotally mounted through a pair of spaced lugs 60 on the one end of the hair clip 14. Preferably, the annular rim 22 supporting the tabs 56 and pivot pin 58 is non-rotatably fixedly attached to the end of the tubular sidewall 20 of the body 12. However, in one illustrated embodiment shown in Fig. 8E, the annular rim 22 and end wall 26 are attached together and rotatably mounted to the end of the tubular sidewall 20 by mated complementary annular shaped lips 62, 64 formed respectively on the annular rim 22 and the end of the sidewall 20. In this one embodiment, the rotation of the annular rim 22 relative to the sidewall 20 will permit the hair clip 14 to be positioned at any desired angular location about the body 12. Aε best seen in Fig. 10, the biasing means 48 preferably is a coiled spring 48 encircling and thus mounted to the pivot pin 58 between the spaced lugs 60 on the hair clip 14. The coiled spring 48 has opposite ends 48A, 48B which engage the body 12 and hair clip 14 and apply a biasing force in a clockwise direction with reference to Fig. 10 that causes the hair clip 14 to pivotally move from the opened position to the closed position relative to the sidewall 20 of the body 12. The user can grip the lever portion 52 of the hair clip 14 and eaεily apply an actuating force thereto which overcomeε the biaεing force of the coiled εpring 48 and causes the spring to yield and permit pivoting of the hair clip 14 to the opened poεition. However, once the user releases the lever portion 52 of the hair clip 14, the biasing force takes over and causeε the hair clip 14 to then pivotally move from the opened position back to the closed position againεt the εidewall 20 of the body 12. Referring to Figε. 13-16, inεtead of providing the hair roller 10 with the tabs 56 of the mounting means 46 rigidly attached to the one annular rim 22 on the body 12, as an alternative thereto the mounting means 46 can be configured to be removably inserted into an end of the body 12 for mounting the hair clip 14 thereto. With respect to this alternative construction which is illustrated in Figs. 13-16, the mounting means 46 now further includeε a female εocket 66 and a base 68 with a male plug 70, and a latch receptacle 72 and latch member 74. The female socket 66 is defined in the end of the body 12 having the one annular rim 22. The base 68 is pivotally mounted to one end of the hair clip 14 and has the male plug 70 attached thereto and projecting outwardly therefrom. The male plug 70 is of a size slightly leεε than the εize of the female socket 66 so as to permit insertion into and mateable fitting within the female socket 66 and thereby securely mount the base 68 within the annular rim 22 of the end of the body 12. The latch receptacle 72 is also defined in the end of the body 12 adjacent to the female socket 66. The latch member 74 is flexibly connected to the baεe 68 adjacent to the male plug 70 and iε inεertable into the latch receptacle 72 upon insertion of the male plug 70 into the female socket 66. The latch member 74 iε movable between a latched poεition, aε εeen in Fig. 13, wherein the male plug 70 iε retained in the female εocket 66 and prevented from being removed therefrom, and an unlatched poεition wherein the male plug 70 iε removable from the female εocket 66. Referring now to Figε. 1, 2 and 8A-8D, an elaεtic hair-anchoring element 16 of the hair roller 10 is made of a stretchible material and is attached to and extends outwardly from the end wall 28. The elastic element 16 is stretchably extendable longitudinally along the sidewall 20 of the body 12 between the annular rims 22, 24 at the opposite ends thereof so as to extend over and thereby anchor thereon the hair wound about the sidewall 20 of the body 12. As seen in Figs. 1, 2, 8B and 10, the elastic element 16 is an endlesε elaεtic loop or band of the material attached to the end wall 28 through a hole 76 therein adjacent to the other rim annular 24. As an alternative seen in Fig. 8A, the elastic element can be an elongated elastic strip 78 of the material attached to the end wall 28 through a hole 80 therein. Furthermore, the elastic element 16 can be attached directly to the end wall 28 of the body 12, as depicted in Figs. 1, 2, 8A and 8B, or to a looped element 81 fixed on one or the other of the end walls 26, 28 of the body 12, as depicted in Figs. 18 and 19. Referring finally to Figs. 1, 2, 3A-3E, 4A-4F, 5A- 5D and 9-11, the hair roller 10 further includes at least one and preferably a plurality of retention elements 82 defined on the other annular rim 24 and end wall 28. The retention elements 82 provide surfaceε about which to secure a portion of the elastic element 16 to the opposite end of the body 12. The retention elements can take any of a variety of different configurations. In Figs. 4A, 4D and 4F the retention elementε 82 are pluralitieε of pegε 84 and teeth 86 which project outwardly from the annular rim 24 on the body 12. Fig. 4B illuεtrates retention elements 82 in the form of internal teeth 88. Figs. 4C and 4E depict retention elementε in the form of eyelets 90 which are attached to and extend outwardly from the other annular rim 24 and end wall 28. Retention elements 82 having other configurations are within the purview of the present invention. Thus, the elastic anchoring element 16, being attached at one end to the respective one annular rim 22 and end wall 26 at one end of the body 12, when stretched to encompasε at leaεt a side portion of the sidewall 20 of the body 12 and then passed around a selected one or ones of the retention elements 82 is retained over the hair wound around the sidewall 20 and thereby provides a means for anchoring the hair roller 10 to the hair wound thereon. Referring to Figε. 20-24, there is shown the hair roller 10 incorporating further modifications of some of the earlier-described components and features of the hair roller 10. First, like the hair roller 10 shown in Figs. 10-12, the sidewall 20 of the elongated body 12 has a plurality of elongated rib or ridge elements 43 defined on and about the exterior surface 20A of the sidewall 20 which are interrupted and absent from the exterior side portion of the sidewall 20 underlying the blade portion 50 of the hair clip 14. However, unlike the hair roller 10 shown in Figε. 10-12, the blade portion 50 of the hair clip 14 on the hair roller 10 of Figs. 20-24 haε a plurality of elongated rib or ridge protruεionε 92 defined on the exterior surface 50B of the blade portion 50 which protrude outwardly therefrom and extend in a helical direction and are spaced apart from one another in a lengthwise direction along the blade portion 50 of the hair clip 14. Preferably, the helical ridge protrusions 92 on the blade portion 50 of the hair clip 14 are substantially aligned with the helical ridge elements 43 on the sidewall 20 of the body 12. Second, unlike in the εidewalls 20 of the earlier- described hair rollers 10, the exterior side portion of the sidewall 20 of the hair roller 10 in Figs. 23 and 24 which underlies the blade portion 50 of the hair clip 14 is inwardly offεet from the remainder of the sidewall 20 which permits the blade portion 50 of the hair clip 14 to overlie and be εeated on the inwardly offset exterior side portion substantially within an exterior profile of the sidewall 50 of the body 12. In the caεe of the body 12 of the hair roller 10 εhown in Figε. 23 and 24, the exterior annular profile is that of a cylinder. The insetting of the blade portion 50 of the hair clip 14 within the exterior annular outline or profile of the hair roller body 12 prevents the hair clip 14 from make an impression or indentation in the hair wound about the body 12. Referring to Figs. 25 and 26, there iε shown other embodiments of the hair roller 10 incorporating additional features in accordance with the present invention. The hair rollers 10 of Figs. 25 and 26 have the same basic partε as moεt of the rollerε described earlier. These same parts are identified by the same reference numerals. In addition thereto, the hair rollers 10 of Figs. 25 and 26 also include a heat retaining member 94 disposed in the interior chamber 30 of the roller body 12. The heat retaining member 94 is adapted to receive heat producing energy, such as εteam in Fig. 25 or electrical current in Fig. 26, from a εuitable external source through the one open end 28 of the body 12 and to retain the heat so produced by the energy for later release to the hair wound around the body 12 during a following period of use of roller 10. In the one embodiment shown in Fig. 25, the heat retaining member 94 includes an annular tube 96 having a donut shape in crosε-εection defining an encloεed internal cavity 98 and a heat retaining material 100, εuch aε a εuitable wax or the like, contained within and εubεtantially filling the internal cavity 98. The annular tube 96 haε radially spaced outer and inner longitudinal walls 102, 104 and a pair of opposite end walls 106 (only one being seen) extending between and interconnecting the opposite ends of the longitudinal walls 102, 104 so as to encloεe the internal cavity 98 and the heat retaining material 100 therein. The inside of the annular tube 96 is acceεεible to the one open end 28 of the body 12 for receiving the εteam to cause heating of the annular tube 96 and the wax 100 therein. In the other embodiment shown in Fig. 26, the heat retaining member 94 includes a pair of electrical conductorε 108, preferably made of a suitable metallic material, having a pair of electrical terminals 108A at one end that are accesεible to the one open end 28 of the body 12 and a heat retaining material 110, εuch as an electrically-conductive ceramic material known as a Positive Temperature Coefficient material, in electrical contact between the pair of electrical conductors 108. The application of an electrical current from the εuitable external source to the terminals 108A causes the current to flow through the electrical conductors 108 and also through the heat retaining material 110 such that the heat retaining material 110 is thereby heated and, in turn, causes heating of the electrical conductors 108 which then retain the heat for later release to the hair wound around the body 12 during a following period of use of roller 10. It should be readily apparent that the hair roller 10 can be provided in different diameter sizeε while retaining all of the above-described features which provide for enhanced rolling and setting of hair for achieving superior hair styling results. Furthermore, the hair roller 10 can be employed in conjunction with a suitable heating apparatus, such as described below. Referring to the drawings, and particularly to Figs. 27 to 29, there is illustrated a multiple hair setting roller heating apparatus of the present invention, generally designated 111. The roller heating apparatus 111 is constructed for heating a plurality of hair setting rollers 10 for use in styling hair. Basically, the roller heating apparatus 111 includes a telescopic enclosure 112. The telescopic enclosure 112 includes a lower housing body 114 and an upper housing extension 116. The lower housing body 114, in turn, includes a lower base 118 for receiving and holding a quantity of water therein and an upper annular sidewall 120 that is attached to and extends upward from the lower base 118. The upper annular sidewall 120 defines an open upper end 122 of the lower housing body 114. The upper housing extension 116 is mounted through the open upper end 122 and within the upper sidewall 120 of the lower housing body 114. The upper housing extension 116 is mounted within the lower housing body 114 such that it may undergo sliding telescopic movement along the upper sidewall 120 of the lower housing body 114 respectively toward and away from the lower base 118 thereof. The upper housing extension 116 is movable relative to the lower housing body 114 between an upper extended condition, as shown in Fig. 28, wherein the upper housing extension 116 is displaced away from the lower base 118 of the lower housing body 114 and a lower contracted condition, as shown in Fig. 29, wherein the upper housing extension 116 is disposed adjacent to the lower base 118 of the lower housing body 114. Defined within the telescopic enclosure 112 by the lower houεing body 114 and the upper housing extension 116 is a heating chamber 124. When the upper housing extension 116 is in the extended condition relative to the lower housing body 114, the heating chamber 124 has a first volume for containing a first plurality of the hair setting rollers 10. On the other hand, when the upper housing extension 112 is in the contracted condition relative to the lower housing body 114, the heating chamber 124 then has a second volume that is smaller than the firεt volume for containing a εecond plurality of the hair setting rollerε 10 which are εmaller in number than the first plurality of hair setting rollers 10. Disposed within the lower base 118 of the lower housing body 114 are means, such as a heating element 126, for generating heat in the heating chamber 124 of the telescopic enclosure 112. The heating element 126 per se can be a conventional electric unit well-known to thoεe of ordinary skill in the art. Referring now to Figε. 28 through 33, the lower housing body 114 of the teleεcopic enclosure 112 includes the integrally connected lower baεe 118 and upper sidewall 120 and a bottom cover 128 underlying and connected to the lower base 118. Theεe parts of the lower housing body 114 together define a receptacle 130 for receiving and holding a quantity of water therein. The lower base 118 preferably includes a lower annular sidewall 132 that is attached at an upper end to a lower end of the upper annular sidewall 120 of the lower housing body 114. The lower annular sidewall 132 has a diameter lesε than the diameter of the upper annular εidewall 120 so as to define an annular recessed region 134 surrounding the lower annular sidewall 132 and underlying the upper annular sidewall 120. An electrical cord 136 may be stored in the annular recessed region 134 in a wrapped relation about the lower annular sidewall 132. The electrical cord 134 extends through the lower base 118 to connect with the electric heating element 126 disposed in the lower base 118. As mentioned earlier, the lower base 118 also preferably includes a removable bottom cover 128. The bottom cover 128 is removably attached to a bottom edge portion of the lower annular sidewall 132 of the lower base 118 thereby affording access to the heating element 126 disposed within the interior of the lower base 118. Referring now to Figs. 28, 29 and 34 through 40, the upper housing extension 116 of the telescopic enclosure 112 is preferably an annular sleeve 138 of cylindrical εhape concentric with the cylindrical shape of the upper sidewall 120 of the lower housing body 114. The annular sleeve 138 iε slightly smaller in diameter than the upper sidewall 120 of the lower housing body 114. The sleeve 138 haε axially εpaced opposite top and bottom ends 138A, 138B which are open such that the top end 138A of the sleeve 138 defines an open top of the heating chamber 124 of the telescopic enclosure 112 for placing the rollers 10 into the heating chamber 124 and removing the rollers 10 from the heating chamber 124. Referring to Figs. 34 and 36, the sleeve 138 has a pair of arcuate shoulders 140 formed on and projecting radially inwardly from the interior surface of the top end 138A of the sleeve 138. The εhoulderε 140 terminate at opposite ends 140A which are angularly spaced from one another on the opposite sides of the sleeve 138. A small depresεion 142 is formed on the underside of each shoulder end 140A. A plurality of vertical grooves 144 are formed in the exterior surface of the sleeve 138. The vertical grooves 144 extend a short distance downward parallel to the longitudinal axis of the sleeve 138 from the top end 138A of the sleeve 138 and asεiεt the user in gripping of the top end 138A of the sleeve 138 when εliding the upper houεing extension 116 from itε contracted to extended condition. Referring to Figs. 28 and 40, the upper housing extension 116 also includes a first protruding detent element 146 formed on the exterior of and adjacent to the bottom end 138B of the cylindrical sleeve 138. Referring also to Figs. 28 and 33, the lower housing body 114 also includeε upper and lower second recesεed detent elements 148, 150 formed on the interior of and adjacent to the respective upper and lower ends of the upper sidewall 120 of the lower housing body 114. The first protruding detent element 146 is shaped complementary to and thus is matable with the upper second recessed detent element 148 when the upper housing extension 116 is in its extended condition. When the upper housing extension 116 is then moved to its contracted condition, the first protruding detent element 146 is mateable with the lower second recesεed detent element 150. The mating of the firεt protruding detent element 146 at εeparate inεtances with the reεpective upper and lower second recessed detent elements 148, 150 correspondingly releasably retains the upper housing extension 116 in the respective extended and contracted conditions of the telescopic enclosure 112. Referring again to Figs. 27 through 29, the roller heating apparatus 111 also includeε a top cover or lid 152. The lid 152 removably fits on the open top of the upper housing extension 116 of the telescopic enclosure 112 to enclose the rollers 10 within the heating chamber 124 thereof. Referring now to Figs. 41 through 43, the lid 152 has a generally flat top panel 154, a peripheral flange 156 attached to and surrounding the top panel 154 and extending downwardly therefrom, and a central knob 158 attached to the exterior top εurface of the top panel 154. A pair of hook elementε 160 are attached at and extend downwardly from opposite portions of the lower peripheral edge of the flange 156. The hook elements 160 are insertable through the spaces between the ends 140A of the shoulders 140 when the lid 152 is placed on the top end 138A of the annular sleeve 138 of the enclosure 112. Preferably, each hook element 160 includes a dimple 162 which interfits with the respective depression 142 in the shoulder 140 which it underlies to retain the lid 152 in a locked position on the sleeve 138. The lid 152 iε rotatable between an unlocked poεition in which the hook elements 160 are angularly displaced from although are below the shoulderε 140 and a locked poεition in which the hook elements 160 underlie the shoulders 140 thereby securing the lid 152 on the upper housing extension 116. Thus, the pairs of hook elements 160 and shoulder ends 140A combine with the shoulders 140 on the top end 138A of the sleeve 138 to form a releasable locking arrangement that detachably attaches the lid 152 on the open top of the upper housing extenεion 116. Referring to Figε. 27, 29, 33 to 35 and 44 to 47, the apparatuε 111 alεo preferably includeε a water level viewing window structure 164. The water level viewing window structure 164 is recessed in a longitudinal portion of the upper sidewall 120 of the lower housing body 114. The water level viewing window structure 164 includes a longitudinal slot 166 defined in a side portion of the upper sidewall 120 of the lower housing body 114 as beεt εhown in Figs. 32 and 33, a recesεed wall portion 168 defined along a εide of the upper houεing extenεion 116 aε best shown in Figs. 34 and 35, and a tubular member 170 as best shown in Figs. 44 through 47 that is mountable through the longitudinal εlot 166 in the lower housing body 114 so that it extendε into the heating chamber 124 of the enclosure 112. Referring now to Figs. 44 through 47, the tubular member 170 of the window structure 164 is open at its opposite top and bottom ends and includes an outer wall portion 172 of generally flat configuration adapted to εlidably fit into and extend between oppoεite vertical edges 166A of the longitudinal slot 166, and an inner wall portion 174 of generally εemi-cylindrical arcuate configuration connected along a pair of opposite longitudinal edges of the outer wall portion 172 and projecting into the heating chamber 124. The recesεed wall portion 168 in the upper housing extension 116 has a generally arcuate configuration substantially conforming to that of the inner wall portion 174 of the tubular member 170 such that the recesεed wall portion 168 of the upper housing extension 116 is concentric with and slidably telescopically moves along the inner wall portion 174 of the tubular member 170 as the upper housing extension 116 is so moved relative to the lower housing body 114 between the extended and contracted conditionε of the telescopic enclosure 112. The concentric shape and telescopic movement of the recessed wall portion 168 of the upper housing extension 116 with the inner wall portion 174 of the tubular member 170 mounted to the lower housing body 114 also functions to guide and limit the upper housing extension 116 to such telescopic movement and prevent concurrent rotation of the upper housing extension 116 of the telescopic enclosure 112 relative to the lower housing body 114 thereof. Referring now to Figs. 48 through 57, the roller heating apparatus 111 also basically includeε a roller εupport aεsembly 176 that support the rollers 10 within the heating chamber 124 of the telescopic enclosure 112. The roller support assembly 176 includes an annular bottom platform 178 that is disposed in the enclosure 112 between the lower base 118 and the upper sidewall 120 of the lower housing body 114, a first plurality of heat transmiεεion rods 180 connected on and extending upright from the bottom platform 178, and a εecond plurality of heat transmission rods 182 insertable into and telescopically movable relative to the firεt rodε 180. As shown in Fig. 33, the lower housing body 114 has a plurality of angularly εpaced apart projectionε 184 formed therein on an annular flange portion 186 defined on the upper end of the lower εidewall 130 of the lower base 118 of the lower housing body 114 where it mergeε with the lower end of the upper εidewall 120 of the lower houεing body 114. The spaced projections 184 underlie and support the roller support assembly 176 at the bottom platform 178 thereof acrosε an open upper end of the lower base 118 and thus above the water contained within the lower base 118. The first and second rods 180, 182 are elongated hollow tubes. The first rods 180 have open upper and lower ends 180A, 180B, whereas the second rods 182 have a closed upper end 182B and an open bottom end. Both first and second rods 180, 182 also have respective longitudinal slotε 188 and 190 defined therein extending between the opposite ends 180A, 180B and 182A, 182B. The second rods 182 are smaller in diameter than the first rods 180. The second rods 182 are telescopically inserted into the first rods 180 through the upper open ends 180A thereof and are mounted therein to undergo telescopic sliding movement between lowered and raised positions relative to the first rods 180, as best seen in Figs. 49 and 53. The lower end 182B of each of the second rods 180 is deformably curled into an annular rim 192 which is matable with respective upper and lower annular recesses 194, 196 formed outwardly from the interiors of the firεt rods 180 at the opposite upper and lower ends 180A, 180B thereof when the second rod 182 is respectively dispoεed at the raised and lowered poεitions relative to the first rod 180. Indentations 198 formed in the sideε of the εecond rodε 182 near their top endε 182A asεiεt the user in grasping of the εecond rods 182 when telescoping the εecond rods 182 upwardly from their lowered to raised positionε. In order to dispose the upper housing extension 116 at the contracted condition relative to the lower housing body 114, the second rodε 182 muεt firεt be retracted into the first rods 180 and thereby disposed at their lowered positions relative to the first rods 180. On the other hand, the upper housing extension 116 must first be dispoεed at the extended condition relative to the lower houεing body 114 in order to extend the εecond rodε 182 from the first rods 180 and thereby dispose the second rodε 182 at their raiεed position relative to the first rods 180. The above-described roller heating apparatuε 111 of the present invention iε utilized in the following manner to heat the hair εetting rollerε 10. A first group of the hair setting rollers 10 are disposed over the first rods 180. If necessary, the upper housing extension 116 may be raised to the extended position and the second rods 182 moved to their raised positions relative to the first rods 180 εo that a second group of the hair setting rollers 10 can be disposed over the second rodε 182. A quantity of water iε be poured into the receptacle 130 formed by the lower housing body 114 before placing the hair setting rollers 10 over the rods 180, 182. The water level viewing window structure 164 allows the level of water to be viewed when pouring water into the receptacle 130 and during operation of the apparatus 110 to determine if the addition of more water is necesεary. The heating element 126 iε then activated to heat the heating chamber 124 and boil the water contained in the receptacle 130, thereby producing steam in the heating chamber 124. The steam rises from the receptacle 130 of the lower housing body 114 into the interior of the heat tranεmission rods 180, 182. The longitudinal slots 188 and oppoεite open upper and ends 180A, 180B of the first rods 180 and open lower ends of the second rods 182B permit passage of the steam therethrough to the hair setting rollers 10 disposed over the first and second rods 180, 182 thereby heating the rollers 10. It is thought that the present invention and its advantages will be understood from the foregoing description and it will be apparent that variouε changeε may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely preferred or exemplary embodiment thereof.
