Abstract

A hair styling device that has a rotating cylinder extending from a body that may be easily grasped by hand. The device allows the cylinder to rotate relative to the body, which remains stationary in the hand of a user. The cylinder has a clamp for clamping hair to the cylinder. The clamp rotates with the cylinder and is used to wind hair up the cylinder while the user holds the body of the device. The direction of rotation of the cylinder may be changed as desired by the user. The ability of a user to rotate the cylinder without rotating the entire device manually eliminates twisting the cord due to turning the entire device as is done with traditional curling irons. Buttons on the device select the direction of rotation of the cylinder.

Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application is a continuation claiming the benefit of Utility application Ser. No. 13/416,020 filed Mar. 9, 2012, which claims the benefit of U.S. Provisional Application No. 61/466,227, filed Mar. 22, 2011, the disclosures of which are hereby incorporated by reference.
  • BACKGROUND OF THE INVENTION
  • Traditional curling irons are well known and have problems that make their use difficult to achieve results. A traditional curling iron requires a user to manually rotate the entire iron to curl hair. This requires two hands to twist a traditional iron many times over to rotate a number of full revolutions to curl a length of hair. During this twisting, the cord can easily become tangled. Also, there is a high likelihood of being burned because two hands are being used and there is usually a limited amount of surface area on a traditional iron that is not heated. Ideally, one hand usage and not tangling cords while winding hair on a curling iron cylinder would be a much better system.
  • SUMMARY OF THE INVENTION
  • The present invention is a hair styling device that has a rotating cylinder extending from a body that may be easily grasped by hand. The device allows the cylinder to rotate relative to the body, which remains stationary in the hand of a user. The cylinder has a clamp for clamping hair to the cylinder. The clamp rotates with the cylinder and is used to wind hair up the cylinder while the user holds the body of the device. The direction of rotation of the cylinder may be changed as desired by the user.
  • In another aspect of the invention, the cylinder has a heating element. Because the cylinder rotates relative to the body, supplying electricity to heat the heating element in the cylinder must be done with contacts that provide an electrical connection while rotating. A first terminal disc has contacts within the cylinder and a second terminal disc in the body has contacts. The first terminal disc is fixed with respect to the cylinder and rotates with it. The second terminal disc is fixed within the body. As the cylinder rotates, contacts on both discs remain in contact to supply electricity to the heating element.

  • DETAILED DESCRIPTION OF INVENTION
  • The hair styling device 10 of this invention has a body 12 designed to be comfortably grasped. The body 12 is also designed to contain electrical and mechanical parts that make the device 10 function. A cylinder 14 extends from the body and is rotatable with respect to the body 12. A motor 22 is used to cause the cylinder 14 to rotate relative to the body. The motor shaft 24 is connected to rod 28 that runs the length of the cylinder 14. Rod 28 is threaded at its end 30 opposite motor 22 and includes a first terminal disc 32 that includes inner and outer contacts 34, 36 that are concentric annuli. Each concentric annular contact 34, 36 is affixed concentrically with respect to rod 28 and lies flat within the first terminal disc 32 as shown in FIG. 4. The terminal disc 32 is molded onto rod 28 and rotates with it. The terminal disc 32 includes upwardly extending tabs 33 that fit within the interior of the cylinder 14 and prevent it from rotating with respect to the terminal disc 32. Thus, rotating rod 28 will rotate the cylinder 14. An outer groove 29 is located on the exterior of the first terminal disc 32. Wires 38 connected to the contacts 34, 36 extend from the terminal disc 32 into the cylinder 14 to supply power to heating elements 40 in the cylinder 14. When the device 10 is assembled, cylinder 14 extends from the body 12 and this places the first terminal disc 32 adjacent to a second terminal disc 44. The cylinder 14 is held within the body by ribs 45 that extend inwardly to fit within the outer groove 29 on the first terminal disc 32. The second terminal disc 44 has inner and outer contacts 46, 48. These contacts 46, 48 are each bent upwardly on opposite sides as shown in FIG. 4. Contacts 46, 48 are the same diameter as contacts 34, 36 respectively. Contacts 46, 48 act as springs, which ensure multipoint brushing contact with contacts 34, 36. Wires 47 extend into the body 12 to connect to the electrical supply delivered through cord 49. The second terminal disc 44 is held stationary within the body 12 by rib 50 that extends into a slot 52 within in the body. The ribs 45 can be seen in FIG. 3 and one of the ribs 45 can be seen in FIG. 5. Because the first terminal disc 32 is rigidly affixed to rod 28, this in turn will fix the cylinder 14 to the body 12 because the ribs 45 hold terminal disc 32 within the body and cylinder 14 is held against terminal disc 32 with nut 54 on the end 30 of rod 28. Nut 54 is within end cap 54 that receives end plug 58. The end plug 58 conceals the nut 54 and rod end 30.
  • The cylinder 14 has a hair clamp 60 near the body 12. The clamp 60 is affixed to the cylinder 14 and is adapted for clamping hair to the cylinder 14. A helical torsion spring biases the clamp 61 against the cylinder 14. A thumb lever 64 is used to open the clamp 60 by pressing it down toward the cylinder 14. The lever 64 is positioned near the body 12 so a user may press the lever 64 toward the body 12 without touching the cylinder 14.
  • Motor 22 that rotates the cylinder 14 is attached to mounting bracket 66, which is affixed to the body 12 with screws 67. The motor 22 is connected to a power source, which is typically an electrical outlet in a home. The motor 22 is capable of rotating the cylinder 14 in either direction depending on the desire of the user. The motor 22 direction is controlled by pressing one of the directional buttons 68 that determine left or right. The directional buttons 68 are on either side of a go button 70. The user presses the correspondingly marked directional button 68 for left or right to determine which direction the cylinder will rotate. Pressing the go button 70 will make the cylinder 14 rotate after the desired direction is selected. Left is selected for use of the device 10 on the left side of the head and Right is selected for use on the right side of the head so that hair is rotated away from the head. The rod 28 is supported in front of the motor 22 by bushings 74 that are held in a bushing cradle 76. The bushings 74 are low friction bronze and are spaced apart for stabilizing the rod 28 within the body 12. The bushing cradle 76 is fixed to the body as shown in FIG. 5. FIG. 5 shows only half of the bushing cradle 76. The bronze bushings 74 stabilize rod 28 within the bushing cradle 76 to maintain clearance between the first terminal disc 32 and the body 12 adjacent to the terminal disc 32. This maintains the groove 29 in a complementary relationship with ribs 45 so the ribs 45 hold the cylinder 14 to the body 12, with minimal friction. Between the bushing cradle 76 and motor 22 are adapters 80. The adapters 80 are so that the smaller motor shaft 24 and larger rod 28 may be easily joined together. The motor adapter 82 has apertures 84 that accept evenly spaced prongs 86 on the rod adapter 88. This construction facilitates easy assembly due to the fact that rod 28 may be assembled into the body 12 after motor 22 is fastened in place with screws 67 that are driven through motor mounting bracket 66.
  • The device 10 includes temperature control buttons 96 that are above a main power button 98. The temperature control buttons 96 are used to raise or lower the temperature of the cylinder 14. This is done by the buttons 96 being electrically connected to circuit board 98 that will then, based on what is input, regulate the amount of current that is sent to heating elements 40 within the cylinder 14. The temperature selected through the use of buttons 96 will be displayed on temperature display 102.
  • A stand 106 is attached to the cylinder 14 as shown in FIG. 1. The stand 106 is an arcuately shaped wire that pivots about its attached ends 108 that extend into a bracket 110 on the cylinder 14. The stand 106 may be used in the extended position shown in FIG. 1 when the device 10 is hot and resting on a surface. During use, the stand 106 may be folded so that it is adjacent to the body.
  • To use the device 10, hair 112 is clamped to the cylinder with clamp 60. The hair 112 is clamped near its ends as shown in FIG. 6. The user then selects the directional button 68 corresponding to the side of the head that the device will be placed on. In FIG. 6, this would correspond to the directional button marked “R” for right. After the corresponding directional button 68 is pressed, the go button 70 is held down so that the cylinder 14 winds the hair 112 near the head. The hair is wound outwardly from the head and doing so requires the rotational direction of the cylinder be changed to accomplish this. The go button 70 is released to stop the cylinder 14 from rotating. With the hair 112 as shown in FIG. 7, the clamp 60 is released. Fingers may be run through the hair to give beautiful waves through the hair 112.
  • The device is not limited to the details given above, but may be modified within the scope of the following claims.
