DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1A-1C, a hair accessory application device in accordance with an illustrative embodiment of the present invention is shown and generally represented by reference numeral 10. The hair accessory device 10 includes a body or handle portion 12 and a head portion 14. Hair accessories, such as beads 16, for example, may be threaded or received over one or more strands of hair using device 10.
The handle portion 12 may be ergonomically shaped to comfortably and conveniently be held by an operator. Preferably, the handle portion has a power button 18 for allowing an operator to control the operation of the device 10. The power button 18 can be shaped in a variety of ways and can be placed on the side of the handle portion 12 as shown, or in any other location convenient to an operator. In an alternative embodiment, the handle portion can be in the form of a control interface having any of a variety of input selectors (e.g., buttons, knobs, dials, touch-pads or touch-screens, etc.) for starting, stopping or otherwise adjusting the operation of the hair accessory device 10. The control interface can also have a variety of output indicators, such as, for example, visual indicators (e.g., LED/LCD displays, etc.), audible indicators (e.g., beeps, automated voice, etc.), or tactile indicators (e.g., vibration, heat, etc.).
Located on the head portion 14 is a rotating bead holder 20 that can hold a plurality of beads 16. Preferably, the bead holder 20 has a circular or disk-shaped profile and a plurality of grooves 22 to hold a multitude of beads 16, each bead placed within a groove 22. Also located on the head portion 14 is a hair holder 24. The hair holder 24 can have thin metal bars or rods that hold one or more strands of hair in place so that a bead 16 may be more easily attached to the hair. FIG. 2A shows a pushing arm 25, which can be used to push the beads 16 onto the user's hair while the hair holder 24 holds the one or more strands of hair.
In order to keep the beads 16 from falling out of the device 10 or being knocked out of a groove 22, a transparent cover 26 can be placed over the head portion 14. The cover 26 can be made to selectively pivot about a hinge so that it may be easily opened and closed. This allows for the beads 16 to be easily replaced back into the rotating bead holder 20. In a preferred embodiment, the hinge is located near the hair holder 24. The cover 26 can be made to open up to a certain angle, such as 90 degrees, for example, or can be completely removed from the device 10. The transparent cover 26 can be made from plastic or any other material that would allow an operator to see the beads 16 within the device 10 while the beads 16 are being protected. In an alternative embodiment, the cover 26 can also be opaque or non-transparent.
Referring to FIG. 2B, within the hair accessory device 10 is a drive assembly 27 comprising a motor 28 with a gear box, a drive shaft 32, a drive gear 34 and an eccentric wheel 46. Preferably, the motor 28 is powered by batteries 30. However, the motor can be powered by any other applicable power source. For example, in an alternative embodiment, the hair accessory device 10 may run from an electric cord (not shown) connected to an electric power source. In the preferred embodiment, the motor 28 is connected to a drive shaft 32. The drive shaft is connected to a drive gear 34. The motor 28 causes the drive shaft 32 to rotate, which in turn, causes the drive gear 34 to rotate about an axis that is perpendicular to the rotation of the drive shaft 32. Upper contact reed 36 and lower contact reed 37 are used to control the circuit that enables the device 10 to operate. A ratchet 38 rotates the rotating bead holder 20 with beads 16 so that once a bead 16 is placed in an operator's hair, the next bead 16 will be in position to be placed in the hair, as will be described in further detail below.
As illustrated in FIG. 3, the rotation of the motor 28, drive shaft 32 and drive gear 34 causes an eccentric wheel 46 to also rotate. This controls the horizontal movement of the hair holder 24 and the pushing arm 25. A top circular knob 48 is located on the top surface of the eccentric wheel 46. As the eccentric wheel 46 rotates, the top circular knob 48 moves back and forth within a slot 50 in the pushing arm 25, causing the pushing arm 25 to move forward and backward. On the bottom surface of the eccentric wheel 46 is a bottom circular knob 52. This bottom circular knob 52 fits within a groove 54 of a flat member 56. The flat member 56 is located between the drive gear 34 and the pushing arm and has two posts 58 located on the top surface. The hair holder 24 has two poles 60, which are placed into the two posts 58 so that the flat member 56 and the hair holder 24 move in conjunction with one another. As the eccentric wheel 46 rotates, the bottom circular knob 52 moves within the groove 54 of the flat member 56 and causes the flat member to move forward and backward, in the opposite direction as the pushing arm 25. As the flat member 56 moves back and forth, the hair holder 24 moves in conjunction with it, in the opposite direction as the pushing arm 25.
FIG. 4 shows the hair accessory device 10 as it proceeds through four main stages. Stage 1 shows the beginning, where a tuft of hair 62 is placed within the hair holder 24. A bead 16 is in position to be pushed onto the tuft of hair by the pushing arm 25. The bead 16 will be pushed over a slide plate 64, so that the bead will be expanded. FIG. 5 shows a bead 16. Each bead 16 is comprised of an upper part 40, a lower part 42 and a spring 44 in the middle. Preferably, the slide plate 64 is generally in the shape of two wedges, in which the narrow ends are facing the bead 16 and the broad ends are facing the tuft of hair 62. As the bead 16 is pushed over the slide plate 64 by the pushing arm 25, the upper part 40 and the lower part 42 are separated from one another against the force of the spring 44. This can be seen in FIG. 4 at stage 2. When the upper part 40 and lower part 42 are fully separated, the tuft of hair 62 can fit between the coils of the spring 44. After the bead 16 continues to move over the broad edge of the slide plate 64 and beyond the slide plate, the upper part 40 and lower part 42 return to their initial state of being in close contact, with the tuft of hair 62 firmly in place between the coils of the spring 44. This is shown at stage 3 of FIG. 4. Stage 4 shows the bead 16 on the tuft of hair 62, with the hair holder 24 and pushing arm 25 returning to their initial states. The next bead 16 is then in position to be placed upon another tuft of hair 62.
FIG. 6 shows the bead refilling mechanism. At stage 1, the ratchet wheel 66 rotates counterclockwise until the circuit of the upper contact reed 36 opens. At stage 2, the ratchet wheel 66 rotates clockwise and the ratchet 38 pushes the rotating bead holder 20 to rotate. At stage 3, the ratchet wheel 66 continues to rotate until making the circuit of the lower contact reed 37 to open. The rotating bead holder 20 is then rotated one step as seen at stage 4. A detent 68 can fix the rotating bead holder 20 into an incremental position. FIG. 7 shows the circuit to control the movement of the pushing arm 25, the rotating direction of the motor 28 and the bead refilling mechanism.
While a preferred embodiment of the invention has been herein disclosed and described, it is understood that various modifications can be made without departing from the scope of the invention.
