Hair winding device for use in perming hair

Abstract: A hair perming device includes a rotating member (23) connected through a motor shaft (22) to a motor (21) provided in a housing (17) of a body (12). A clip (13) is composed of a first holding member (25) and a second holding member (26), which are energised so that their respective ends are pressed against each other. The first holding member (25) is attached to the end of the rotating member (23) in the direction of the center of its rotating axis. When a switch (24) is turned on in this condition, the rotation of the rotating member (23) is transferred to the first holding member (25) and the clip (13) turns in the direction shown by the arrow. Accordingly the hair (30) held at the end of the clip (13) is twisted at a designated speed in the direction shown by the arrow.

Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a hair winding device for use in perming hair, and particularly to a hair winding device for use in special hair permanent process such as a permanent spiral. Description of the Background Art Fig.7 is a diagram schematically showing the structure of the hair winding device for use in a hair perming process as described in U.S.5,865, 193. Referring to this diagram, the body 17 to be held with the hand contains a motor 21 inside, and the motor 21 has a motor shaft 22 to which a rod engaging member 61 is detachably connected. The motor 21 is driven when a switch (not shown) is depressed and then the rod engaging member 61 is driven and starts rotating through the motor shaft 22. Fig.8 is a diagram showing the perm-dressing hair winding device of Fig.7 with a perm-dressing rod 62 attached to the rod engaging member 61. Referring to this diagram, the motor 21 in the body 17 is driven to cause the rod 62 to rotate, and thus the hair to be processed can be wound on the rod 62 in a shorter time than when carried out manually. In this way, even an unskilled person can easily wind hair in a short time prior to the application of a cold permer 71 to curl the hair as shown in Fig.9. However, although the perm-dressing hair winding device described above is useful for common permanent waves, it is difficult to use this hair winding device in the process of applying a special permanent such as the spiral permanent. Fig. 10 shows hair processed in a permanent spiral. Referring to the diagram, the process of applying such a spiral permanent wave 72 includes: slicing the hair in blocks, twisting every several tens of the sliced hairs into a strand, further twisting every several strands together as shown in the diagram, and applying a permanent treatment to the hair. While applying the spiral permanent requires the process of twisting the hair, the perm-dressing hair winding device can only wind the hair in a given direction. Accordingly, when applying a special permanent such as the spiral permanent that requires twisting the hair or winding the hair into small spirals, the preparatory process must be performed manually, which is actually a time-consuming work even for a skilled worker. A hair wave formation tool is shown in JP10033241A which winds up hair by rotating a hair fixing clip clipping the tip of the prescribed amount of the hair. JP 09098826 describes a hair winding device with a detachbly connected rod member. SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and an object of the invention is to provide a hair winding device for use in a hair perming process which allows accurate hairdressing to be done in a shorter time in the process of applying a special permanent such as a spiral permanent that requires twisting hair, for example. To achieve the object above, a hair winding device for use in a hair perming process comprises a rod on which hair to be processed can be spirally wound; the rod having a rod-like body on which cuts extending inwardly in the axial direction of the body are formed on the respective ends thereof; holding means comprising a clip removably holding one end of the rod, said clip including a first holding member, and a second holding member which are connected to each other and capable of turning in such a direction that their respective distal ends are pressed against each other or separated, and energising means which energize said first holding member and said second holding member in such a direction that their respective ends are pressed against each other, and rotating means connected to the proximal end of said first holding member for rotating said first holding means around its axial direction, and enabling said rod held by said clip to rotate substantially around its axial direction. With this structure, the hair can be twisted between the roots and the ends and thus the hair can be twisted in a stable manner. The end of the rod is held between the end of the first holding member of the clip and the end of the second holding member. The rotating means may comprise a motor and a rotating member connected to a rotating shaft of the motor, and the first holding member may be connected to the rotating member with its center of rotation aligned with the axis of rotation of the rotating member. With this structure, the held hair can be twisted in the held position without shaking. According to the invention, the rotating power of the rotating means can be effectively transferred through the first holding member in such a direction that the hair is twisted. The hair can be wound on the rod spirally and continuously, so that the hair can be wound into spirals with desired winding diameter in a shorter time and in a stable manner. These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description by way of example only of the present invention when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Fig. 1 is a diagram schematically showing the structure of a hair winding device for use in a hair perming process not according to the invention. The diagram shows the body in a partially cutaway manner and shows a comb 14 attached to the side of the body 12 near the end. Fig. 2 is a diagram schematically showing the structure of a rotation controller connected to the perm-dressing hair winding device shown in Fig. 1 and 5 in order to supply power to it. Referring to the diagram, its body 36 which is shaped like a rectangular box and to which the power-supply cord 31 is connected contains a battery 37. A clip (not shown), for example, is attached to the body 36 so that the hairdresser can carry it on his/her belt, for example. The body 36 has a rotation direction changing switch 38 on its upper surface, which is operated to control the direction of rotation of the motor 21 shown in Fig. 1 and 5. The body 36 also has on its upper surface a rotation speed changing switch 39 for controlling the magnitude of the voltage supplied to the motor 21. More specifically, turning the rotating speed changing switch 39 to "F" side causes the supply voltage to the motor 21 to rise to increase the speed of rotation of the motor 21, and turning it to "S" side slows down the rotating speed of the motor 21. Thus the speed of rotation of the motor 21 can be controlled to desired speed by operating the rotating speed changing switch 39. Fig. 3 is a diagram showing the structure for attaching/detaching the comb 14 to and from the housing of the body 12 shown in Fig.1 and 5, and Fig.4 shows the cross section taken along the line IV-IV in Fig. 3. Referring to the drawings, a projecting part 44 shaped like "U" in section is attached to the housing as shown in Fig.3; the projecting part 44 has cuts 45 in the upper ends of both side walls. A fitting member 41 shaped like "U" in section is attached in the vicinity of the end of the body of the comb, 42, which can be turned through the shaft 43. As shown in Fig. 4, the fitting member 41 is sized and shaped so that it can be fitted closely over the outside of the projecting part 44. The cuts 45 of the projecting part 44 are sized and shaped so that the shaft 43 of the comb body 42 can be inserted therein from above. When attaching the comb body 42 to the housing, the fitting member 41 is set in the position as shown in Fig.3(1). Then, as shown in Fig.3(2), the shaft 43 is fitted in the cuts 45 of the projecting part 44 from above. In this case, the fitting member 41 does not prevent the shaft 43 from fitting in the cuts 45 since the fitting member 41 is in the posture as shown in Fig.3(1). When the shaft 43 has been put in the cuts 45 of the projecting part 44, the shaft 43 abuts on the bottom of the cuts 45, so that the comb body 42 cannot move further downward. In this condition, the fitting member 41 is turned in the direction shown by the arrow shown in Fig.3(2) and moved to the position shown in Fig.3(3). In this condition, as shown in the sectional view of Fig.4, the bottom of the fitting member 41 is positioned on the outside of the bottom of the projecting part 44, which prevents the fitting member 41 from moving upward. In this way, the shaft 43 and the cuts 45 prevent the comb body 42 from moving down and the fitting member 41 and the projecting part 44 prevent it from moving up, thus firmly fixing it to the housing. Since the end of the comb body 42 on the side of the housing abuts on the surface of the housing, the comb body 42 can be securely affixed to the housing without turning on the housing. When removing the comb body 42 from the housing, the fitting member 41 is turned from the position of Fig.3(3) to the position of Fig.3(2), and then the comb body 42 is pulled out upward. Fig. 5 is a diagram schematically showing the structure of a hair winding device for use in a hair perming process according to the invention. Referring to this diagram, the perm-dressing hair winding device includes the body 12 which can be held manually in a hand by a hairdresser and a clip 13 attached to an end of the body 12. Specifically the body 12 is composed of a tube-like housing, a motor 21 contained inside the housing, and a rotating member 23 detachably fixed to the motor shaft 22 of the motor 21. The motor 21 is supplied with power through a power-supply cord 31 connected to the rear end of the housing, and which is controlled to rotate and stop by switching on or off a switch 24 provided approximately in the middle of the housing. The clip 13 is composed of a rod-like first holding member 25 and a rod-like second holding member 26 connected to the first holding member 25 through a pivot and capable of turning on the pivot. The first holding member 25 and the second holding member 26 are energised by energising means, e.g. a spring 33, attached around the pivot in such a direction that their respective ends are pressed against each other. The rear part of the first holding member 25 is detachably attached to the rotating member 23, so that the first holding member 25 rotates around its axial direction as the rotating member 23 rotates. The comb 14 used to tidy and arrange the hair in the hairdressing process is detachably fitted to the housing of the body 12 through a fitting member 41. The structure for the attachment will be described in detail later. The first holding member 25 and the second holding member 26 forming the clip 13 hold a rod 51 between their respective ends, instead of directly holding the hair 30. When the switch 24 on the body 12 is turned on in this condition, the clip 13 turns in the direction shown by the arrow. Then the rod 51 attached to the end of the clip 13 also turns in the direction shown by the arrow. When the rod 51 rotates with the end of several tens of threads of hair 30 to be processed wound on the rod 51 in an oblique direction near the clip 13, the hair 30 is spirally wound on the rod 51 as shown in the diagram. In this way, special hairdressing like spring permanent that requires winding the hair in small spirals can be automatically performed with a stable winding diameter. Fig. 6 is a diagram showing the rod 51 removed from the clip 13 after the hair 30 has been wound on the rod 51 with the hair winding device of Fig. 5. Referring to the diagram, the body 52 of the rod 51 has a cut 53 and a cut 54 on both its ends as shown in the diagram. After the hair 30 has been wound on the body 52, a rubber 55 etc. is set across the cut 53 and the cut 54 to prevent the hair 30 from loosing. Thus the hair can be kept in the wound state and the permanent process can be performed in a stable manner. Conventionally, the elaborate work of spirally winding the hair nas been carried out by hand. However, using the rod 51 with the perm-dressing hair winding device allows even unskilled persons to make stable windings in a shorter time. While the perm-dressing hair winding device and the rotation controller 35 are constructed as separate units, they can be formed as an integral unit. Further, while the comb 14 is detachably attached to the perm-dressing hair winding device, it is not always necessary to attach the comb 14 to the perm-dressing hair winding device.
