Continuation of application Ser. No. 81,291, Ian. 9, 1961. This application Dec. 24, 1964, Ser. No. 422,072 7 Claims. (Cl. 132-40) This is a continuation of application Serial No. 81,291, filed Jan. 9, 1961 and entitled Hair Roller, which is now abandoned.

This invention relates to a device for forming curls in a head of hair and, more particularly, relates to the combination of a cylindrical form on which a strand of hair is to be wound and means to keep the wound hair in place on the cylindrical form until the curl sets.

Various expedients have been suggested heretofore for retaining a wound strand of hair on a cylindrical form but, in general, the best expedient is a bobby pin or like means that will positively clamp the wound strand in place. If a conventional bobby pin is employed, however, the user must hold the wound cylindrical form with one hand and use the other hand, first, to grope for a bobby pin, and then to maneuver the bobby pin into an effective clamping position. This procedure is both awkward and time consuming.

The present invention remedies the situation by interconnecting the cylindrical form and the bobby pin in such a manner that the two cannot be separated, and it never becomes necessary for the user to grope for a bobby pin. The pin is mounted on the cylindrical form in a manner such that it is not only retractable, but it is held in substantially parallel relationship with the outer surface of the cylindrical form at all times so that the user may advance and retract the pin to and from its clamping position without groping and without maneuvering the pin to place the pin in position to be moved. The pin is thus moved by a simple push-pull reciprocal action on the pin when so held in parallelism with the cylindrical form.

A certain problem arises in that the bobby pin must clamp the wound strand of hair to the cylindrical form at whatever point around the circumference of the cylindrical form will result in the cylindrical form being held close to the users head. The bobby pin must be positioned to engage the strand of hair as close to the head as possible. The problem is to mount the bobby pin on the cylindrical form inseparably and retractably and yet to permit the retracted bobby pin to be shifted to any circumferential point of the cylindrical form.

This problem is solved by mounting the bobby pin retractably in a retainer means that is journaled for rotation in the cylindrical form near one end thereof, and which also serves to hold the bobby pin in substantially parallel relationship with the cylindrical form when in retracted position.

Initially, the bobby pin is retracted to permit the end of the strand of hair to be positioned on the circumference of the cylindrical form. The bobby pin is then advanced to clamp the end of the strand for the purpose of carrying out the winding operation. After the strand of hair is fully wound onto the cylindrical form, the user retracts the bobby pin, rotates the retracted bobby pin and the retainer in which the pin is mounted for correct positioning of the retracted bobby pin circumferentially of the cylindrical form, and then advances the bobby pin to its effective clamping position to clamp the fully wound strand of hair and to hold the wound cylindrical form close to the users head while the hair dries to set the curl.

Another problem that arises is that the bobby pin must not only clamp the end of the strand of hair to the cylindrical form prior to the winding operation, but the bobby 3,241,561 Patented Mar. 22, 1966 "ice be retracted without interfering with the fully wound.

strands and later to be advanced over the fully wound strand of hair to clamp the fully wound strand as close as possible to the users head.

This latter problem is solved by shaping the bobby pin.

so that its outer finger or leg is positioned in yieldable contacting relationship with the outer surface of the cylindrical form substantially throughout the length of the finger or leg of the pin. This position and shape of the pin leg or finger serves to clamp the end of the strand of hair tightly on the cylindrical form, allows the strand to be wound tight on the roller without interference from the pin, and enables the user to retract the pin and advance the pin to clamp the fully wound hair at. the closest point to the users head. There is an additional advantage accruing to this configuration of the bobby pin in cooperation with the cylindrical form and that is the full benefit of the spring action of the bobby pin is directed along substantially the entire length of the cylindrical form for initial clamping action of the strand of hair to facilitate the winding of the strand on the cylindrical form and for the subsequent clamping action of the fully wound strand of hair.

A further feature of one practice of the invention is that the leading end of the hobby pin is flexed in its retracted position to a divergent configuration. The divergent configuration causes the advancing bobby pin to slide easily over the wound strand, rather than through the wound strand or under the wound strand. This feature makes it unnecessary for the operator to rrranemver the advancing bobby pin with care to make sure that it grips or clamps the full strand.

The features and advantages of the invention will be understood from the following detailed description, together with the accompanying drawing.

In the drawing, which is to be regarded as merely illustrative FIGURE 1 is a perspective view of the cylindrical form with the bobby pin in its advanced position;

The first embodiment of the invention shown in FIGURES 1 to 6, in clusive, includes a cylindrical form which may be made of any suitable material. In this example, the cylindrical form is made of a suitable plastic. It is helpful to make the cylindrical form of ventilarted construction to promote the drying of the hair wound thereon. For this purpose, the cylindrical form 10 may be provided with numerous distributed perforations 12. Rotatably mounted in one end of the cylindrical form 10 is a retainer 14 for a bobby pin, generally designated 15, which also serves as a guide means for the bobby pin. The retainer 14 is a cylindrical body of suitable material and may be made, for example, of plastic or a suitable metal. To keep the retainer 14 from moving axially relative to the cylindrical form 10, the cylindrical form may be provided with an inner circumferential groove 16 and the retainer may be formed with a complementary circumferential rib or flange 18 that rotatably seats in the groove. It is contemplated that the plastic material of the cylindrical form 10 will be yieldable to the extent necessary to permit the retainer 14 to be forced into its assembled position. The retainer 14 is formed with an eccentrically located aperture or passage 19 for sliding engagement with the hobby pin.

The bobby pin has an inner finger or leg 2% and an outer finger or leg 22, the inner leg being slidably mounted in the passage 19 of the retainer 14. The two legs are interconnected by a loop 24 that serves as a handle at one end of the bobby pin. The leading end of the outer leg 22 is formed with a slight bend 25 to facilitate the movement of the outer leg onto a strand of hair. The inner leg 20 is formed with a suitable stop at its leading end for abutment against the retainer 14 to limit the extent to which the hobby pin may be retracted. In the construction shown, the leading end of the inner leg 20 is bent back on itself to form a loop 2 6 that serves as the desired stop. It is also desirable to limit the extent to which the bobby pin may be advanced on the cylindrical fiorm. For this purpose, the inner leg 20 of the bobby pin may be formed with an offset 28 which, as shown in FIGURES l and 2, serves as a stop at the advanced position of the bobby pin.

The manner in which the device serves its purpose is illustrated by FIGURES 3-6. With the bobby pin 15 retracted to the dotted line position shown at 15a in FIGURE 2, the end of a strand of hair 34 is positioned against the periphery of the cylindrical form 10 and then the hobby pin is advanced to the position shown in FIGURE 3 to clamp the end of the strand of hair to the cylindrical form. The cylindrical form is then rotated counterclockwise to the limit position shown in FIGURE 4 where the strand of hair is completely wound on the cylindrical form. At the final wound position of the cylindrical form the bobby pin 15 may be at any random point around the circumference of the cylindrical form, for example, at the position shown in FIGURE 4.

The next step is for the user to grasp the handle end of the bobby pin and retract the bobby pin out of engagement with the Wound strand of hair. Since the retracted bobby pin is still at the circumferential position shown in FIGURE 4, the retainer 14 is then rotated to place the bobby pin near the base end of the strand of hair as indicated in FIGURE 5. The bobby pin is then advanced to its final effective position indicated in FIGURE 6 at which the outer leg 22 of the bobby pin clamps the wound strand of hair against the periphery of the cylindrical form 10. The bobby pin will then hold the strand of hair in position on the cylindrical form while the hair dries to set the curl.

It is to be noted from the foregoing that when the bobby pin 15 is retracted to the dotted line position shown at 15a in FIGURE 2, the legs 20 and 22 are held in substantially parallel relationship with the outer surface of the cylindrical form 10. In this embodiment, as the stop engages the retainer 14 at a distance from the end of the cylindrical form 10, the leg 20 is held by the aperture or passage 19 in a position such that the bobby pin is positioned at all times in substantially parallel relationship with the outer surface of the cylindrical form. It should also be appreciated that when the outer leg 22 is in the position as shown in FIGURE 2 in solid lines, there is yieldable contact of the leg through substantially its entire length with the outer surface of the cylindrical form to effect a clamping action as the strand of hair is held against the cylindrical form to initiate the winding action such as shown in FIGURE 3. This effective clamping action throughout substantially the entire length of the cylindrical form permits the hair to be wound over the pin such as shown in FIGURE 4 without interference and, when retracted and advanced to a clamping position such as shown in FIGURE 4, without interference. When retracted and advanced to a clamping position such as shown in FIGURE 6, the cylindrical form is as close as possible to the head of the user.

In the embodiment of the invention shown in FIGURE 7, the retainer 14a is in the form of a disc and the cylindrical form 10a is made of flexible plastic with an inner circumferential groove 32 to seat and journal the circumferential edge of the disc. The retainer 14a which may also be made of plastic is formed with a projection or enlargement 34 which serves as a finger piece to facilitate rotation of the retainer by the user.

The bobby pin 15a shown in FIGURES 7 and 8 has inner .and outer legs 20a and 22a. The inner leg is longer than the outer leg and has a bent end portion 35 to serve as a stop. In this embodiment, however, when the stop 35 engages the retainer, the legs 20a and 22a are positioned by the aperture 19a so that substantially parallel relationship is maintained when the bobby pin is retracted fully, as clearly illustrated in FIGURE 8. As aforesaid, this maintenance of this substantially parallel relationship eliminates the groping .and maneuvering of the pin to a position so that the pin may be advanced to its effective clamping position, as shown in FIGURE 7.

The cylindrical form 10a, which may be made of nylon, is formed with two outer circumferential ribs 36 and 38 near its two opposite ends respectively. When the bobby pin 15a is in its limited advance position shown in FIG- URE 7, an offset 42 in the outer leg 22a of the bobby pin forms a shoulder to serve as detent means to yieldingly resist retraction of the bobby pin. At the same time, a loop portion serves as a stop in abutment with the outer side of the retainer 14a. By virtue of this arrangement, the bobby pin is yieldingly retained in its advance position when the device is not in use.

The offset 42 also permits the entire length of the leg 22a to lie flat against the outer surface of the cylindrical form 10a from the offset 42 to the remainder of the leg adjacent the ridge 38. Thus, with the leg 22a held flat against the surface of the cylindrical form 10a, the full clamping efficiency of the bobby pin is utilized both when the hair is initially started and when the strand of hair is fully wound. In other words, this detent 42 permits the cylindrical form to lie flat against the head of the user when the hair is fully Wound and also permits the hair to be Wound around the cylindrical form without interference from the leg 22a so that the wound hair will have the contour of the cylindrical form 10a.

When the bobby pin is in its limit retracted position shown in FIGURE 8, the bent end portion 35 of the inner leg 2 0a abuts the inner side of the retainer 14a to limit the outward retraction of the bobby pin and at the same time the end of the outer leg 22a abuts the outer circumferential rib 36 to yieldingly resist advance of the bobby pin. Thus, the outer circumferential rib 36 serves as detent means to keep the bobby pin retracted and out of the way while the user is initiating an initial winding of a strand of hair on the cylindrical form a.

When the bobby pin is initially advanced from the limit retracted position shown in FIGURE 8, the outer circumferential rib 36 deflects and flexes the leading end of the outer leg 22a of the bobby .pin outward radially of the cylindrical form 10a in the manner shown in FIG- URE 9. It is apparent from an inspection of FIGURE 9 that the divergent fiexure of the leading end of the outer leg 22a will cause the outer leg to slide easily over a wound strand of hair instead of penetrating the wound strand or sliding under the wound strand.

A feature of the second embodiment of the invention is the multiple functions of the outer circumferential rib 36. The rib 36 as well as the rib 38 serve in effect as handles to facilitate the effective gripping of the cylindrical form by the users fingers. The rib 36 also serves as detent means for the bobby pin at the fully advanced position of the bobby pin shown in FIGURE 7 and also serves as detent means at the fully retracted position of the bobby pin shown in FIGURE 9.
