Description

  The present invention relates to a hair iron, and more particularly, to a hair iron having both a curl function and a straight function.

  In conventional hair irons, when curling hair around a cylindrical heat generating surface (curl function) and to stretch hair straightly, the hair is sandwiched between opposing heat generating surfaces (straight function) For each function, one hair iron had to be prepared.

  For this reason, a hair iron of a type that has only one main body and can replace only the heat generating portion has been proposed. However, this type of hair iron has the drawbacks that it takes time to replace the heat generating portion and that it cannot be replaced when the heat generating portion is hot.

In order to eliminate such drawbacks, Japanese Patent No. 2937499 proposes a curling and straightening treatment with one hair iron without exchanging the heat generating part, and is actually on the market. . The hair iron proposed in this patent is a combination of a pair of semicircular cross-section pipes that can be brought into and out of each other, and has a straight function by sandwiching the hair between the opposing surfaces of the pair of pipes. The hair is wound around a cylindrical outer peripheral surface with the help of a hair pressing plate to perform a curling function.
Japanese Patent No. 2937499

  However, in the above-described hair iron, each of the pair of pipes is attached to the half of the grip part and is supported by the rear end of the half part of the grip part, so that the operation is troublesome. Has the disadvantages. In addition, when switching between the curl function and the straight function, it is necessary to change hands one by one. Furthermore, a slide switch that opens a pair of pipes is disposed at a portion of the grip portion that is gripped by a normal hand, and may be operated by mistake. In this way, if operated incorrectly, the two pipes open with the force of the spring, which may cause an unexpected burn.

  Accordingly, an object of the present invention is to provide a hair iron that is easy to operate, can be easily switched between a curl function and a straight function, and can prevent erroneous switching.

The switch bar 86 and the push buttons 88 and 90 are arranged in a straight line, and both ends of the switch bar 86 are in contact with the inside of the push buttons 88 and 90. For the purpose described later, the switch bar 86 is pushed. The buttons 88 and 90 can be moved. Annular flanges 88 a and 90 a are provided on the inner edges of the push buttons 88 and 90, so that the push buttons 88 and 90 do not jump out of the grip 12. As shown in FIGS. 5 and 6, the switching mechanism 72 is provided at the tip of the grip 12 so that the switch bar 86 is disposed at a position where the user of the grip 12 does not normally grip.

  The rear portions 68a and 68b of the clip plate 68 are arranged at a slight distance (referred to as clip plate interval) inside the wall portion 12a of the grip 12, and the length of the switch bar 86 is set on both sides of the grip 12. The clip plate interval (one) is made shorter than the inner width between the wall portions 12a, 12a of the unit, and the switch bar 86 is shifted to the left and right (in the figure) by the amount of the clip plate interval inside the grip 12. 5 and FIG. 6, the lower side is the left and the upper side is the right). The push button 90 acts as a stopper for the left stroke of the switch bar 86, and the push button 88 acts as a stopper for the right stroke of the switch bar 86.

  The switch bar 86 is an elongated round bar as a whole, but has three reduced diameter portions as described below. That is, the switch bar 86 has a first diameter-reduced portion 86a at the right end thereof, and has a normal diameter corresponding to the thickness of the clip plate 68. Subsequently, as shown in FIG. A second reduced diameter portion 86b having a width corresponding to the thickness of the rising portion 14a of the side barrel 14 is formed. In the switch bar 86, a normal diameter portion corresponding to the thickness of the rear portion 16b of the clip plate 68 is left at the left end portion, and subsequently, the thickness of the rear portion 16b of the clip plate 68 as shown in FIG. The width is the third reduced diameter portion 86c.

  The vertically extending long holes 74 and 76 provided in the rising portions 14a and 14b of the lower barrel 14 are round holes 74a and 76a in which a normal diameter portion of the switch bar 86 can be accommodated, and And has elongated holes 74b and 76b having a width slightly larger than the diameter of the second and third reduced diameter portions 86b and 86c of the switch bar 86 and smaller than the diameter of the normal diameter portion ( The round hole portion 74a and the long hole portion 74b are not shown). The round holes 78 and 80 provided in the rear portions 16a and 16b of the upper barrel 16 have a diameter that can accommodate a normal diameter portion of the switch bar 86 in the upper portion. The elongated holes 82 and 84 provided in the rear portions 68a and 68b of the clip plate 68 extend in the vertical direction, and the round holes 82a and 84a in which the normal diameter portion of the switch bar 86 can be accommodated in the lower portion and from there. It has elongated holes 82b and 84b that extend upward and have a width slightly larger than the diameter of the first and third reduced diameter portions 86a and 86c of the switch bar 86 and smaller than the diameter of the normal diameter portion (round). The hole portion 82a and the long hole portion 82b are not shown). In the state shown in FIG. 1 of the hair iron 10 (all closed), the round holes 74a and 76a of the long holes 74 and 76, the round holes 78 and 80, the round holes 82a of the long holes 82 and 84, 84a are aligned on a straight line.

  Next, referring to FIG. 5 and FIG. 6, the upper barrel 16 (the clip plate 68 is integrated) can be swung upward with respect to the lower barrel 14 as shown in FIG. And a curl function for allowing the clip plate 68 to swing upward with respect to the upper barrel 16 (the lower barrel 14 is integrated) as shown in FIG. The setting position will be described.

First, the strator function setting position will be described. This strator function setting position is performed by pressing the left push button 90. When the push button 90 is pushed, the switch bar 86 moves to the right and the push button 88 protrudes from the grip 12. At the same time, the push button 88 and the switch bar 86 are moved by the action of the flange 88a of the push button 88. Stop at the second position shown in FIG.

  In the position shown in FIG. 5, the switch bar 86 is positioned at the positions of the round holes 82 a, 84 a of the long holes 82, 84 of the clip plate 68, while the second reduced diameter part 86 b and the third reduced diameter part 86 b. The diameter portion 86 c is located at the positions of the long holes 74 and 76 of the lower barrel 14. Therefore, when the lever 70 is rotated downward, the second reduced diameter portion 86b and the third reduced diameter portion 86c of the switch bar 86 enter the elongated hole portions 74b and 76b of the elongated holes 74 and 76 of the lower barrel 14 and move downward. 2, the upper barrel 16 is swung upward with the clip plate 68 and takes the position of FIG. 2. In this position, the user places the hair between the lower barrel 14 and the upper barrel 16 and releases the lever 70 so that the upper barrel 16 is automatically swung downward by the action of the spring and closed. The hair iron 10 can exhibit the strator function by sandwiching the hair between the side barrel 14 and the upper barrel 16.

Next, the curl function setting position will be described. This curl function setting position is performed by pressing the right push button 88. When the push button 88 is pushed, the switch bar 86 moves to the left, and the push button 90 protrudes from the grip 12 at the same time. However, due to the action of the flange 90a of the push button 90, the push button 90 and the switch bar 86 are Stop at the first position shown in FIG.

  In the position shown in FIG. 6, the switch bar 86 is positioned at the positions of the round holes 74 a and 76 a of the long holes 74 and 76 of the lower barrel 14, while the first reduced diameter part 86 a and the third The reduced diameter portion 86 c is located at the positions of the long holes 82 and 84 of the clip plate 68. Therefore, when the lever 70 is rotated downward, the first reduced diameter portion 86a and the third reduced diameter portion 86c of the switch bar 86 enter the elongated holes 82b and 84b of the elongated holes 82 and 84 of the clip plate 68 and move downward. By moving, only the clip plate 68 is swung upward and takes the position of FIG. The user places the hair between the clip plate 68 and the upper barrel 16 at this position and releases the lever 70, so that the clip plate 68 is automatically swung downward by the action of the spring and closed. The hair iron 10 can exhibit the curl function by sandwiching the hair between the 68 and the upper barrel 16.

  According to the above switching mechanism 72, setting can be switched between the stratator function setting position and the curl function setting position with one operation unit, and there is an advantage that the user can easily operate. In addition, by integrating the opening and closing mechanisms at the stratator function setting position and the curl function setting position into one, it is possible to reduce the number of parts and reduce the size. In addition, by arranging the switch bar in a portion that is not normally gripped, it has become possible to suppress malfunctions.

  The lower barrel 14 is made of a metal, particularly an aluminum alloy, and as shown in FIG. 3, a frame material 26 extending in the longitudinal direction of the barrel over almost the entire length of the barrel, and a heat insulating material such as a synthetic resin (for example, nylon). The first and second barrel bars 28 and 30 are provided to extend along the frame material 26.

  The skeleton material 26 is formed on the vertical portion 32 and the upper end of the vertical portion 32, the first horizontal portion 34 constituting the joining surface 18 of the lower barrel 14, and the lower end of the vertical portion 32, A second horizontal portion 36 constituting a part of the outer peripheral surface 20 of the lower barrel 14 is provided.

  The first and second barrel bars 28 and 30 are arranged in spaces surrounded by both sides of the vertical portion 32 of the skeleton 26 and the first horizontal portion 34 and the second horizontal portion 36, respectively, It is almost trapezoidal. The surface exposed to the outside of the first and second barrel bars constitutes the remaining portion of the outer peripheral surface of the lower barrel 14 (a part of which is constituted by the second horizontal portion 36 as described above). Therefore, the surface exposed to the outside is curved.

  The hair iron 10 includes a negative ion generator. The negative ion generator includes an elongated ion discharge plate extending along the lower barrel 14. The ion discharge plate is held by holding means constituted by the barrel bar. Specifically, the negative ion generator is embedded in the first and second barrel bars 28 and 30, and is elongated first and second ion discharge plates 38 and 40 (see FIG. 5) extending substantially horizontally along the barrel bar, respectively. 8). A plurality of needle-like protrusions 42 for emitting negative ions, which are arranged on the side edges of the first and second ion discharge plates 38 and 40 facing away from each other and spaced apart from each other, 44 is provided. About three of these needle-like protrusions are preferably provided as shown in the drawing for one ion discharge plate.

  In at least portions of the first and second barrel bars 28 and 30 where the needle-like protrusions 42 and 44 are disposed, spaces 50 and 52 opened to the outside of the barrel through openings 46 and 48 as shown in FIG. Is provided so that negative ions generated by the needle-like protrusions 42 and 44 are discharged to the outside of the barrel.

  Further, a needle-like electrode 54 for releasing negative ions is exposed at the center of the tip of the grip 12 (see FIG. 8). The needle electrode 54 is for blowing out negative ions between the joint surface 18 of the lower barrel 14 and the joint surface 20 of the upper barrel 16. It is preferable that a groove-like recess 56 (see FIG. 3) having a semicircular diameter in cross section extending substantially over the entire length of the barrel is formed at the center in the barrel width direction of the joining surface 20 of the upper barrel 16. By this recess 56, a space 58 extending substantially over the entire length of the barrel is formed between the joint surface 18 of the lower barrel 14 and the joint surface 20 of the upper barrel 16, and negative ions released from the needle-like electrode 54 Through this space 58, it reaches the tip of the barrel. The negative ions from the needle-like electrode 54 act on the hair sandwiched between the lower barrel and the upper barrel mainly at the time of the strator function.

  The first and second ion discharge plates 38, 40 and the needle electrode 54 are connected to a high voltage generator 66 through leads 60, 62, 64, respectively. A high voltage is supplied from the high voltage generator 66. When supplied, negative ions are generated. As described above, the negative ions from the needle-shaped electrode 54 mainly act on the hair sandwiched between the lower barrel and the upper barrel during the strator function, and the first and second ion discharge plates 38 and 40 Negative ions from the needle-like protrusions 42 and 44 act on the hair wound around the lower barrel and the upper barrel mainly during the curl function. The negative ions from the needle-like protrusions 42 and 44 also act on the hair that is sandwiched and slid between the lower barrel and the upper barrel before and after the iron portion during the strator function.

  According to the negative ion generator described above, as described above, negative ions are emitted from a plurality of needle-like electrodes arranged at intervals in the longitudinal direction on the ion discharge plate extending along the longitudinal direction of the barrel. Therefore, there is an effect that negative ions are spread throughout the hair spreading in the longitudinal direction of the barrel. The needle-shaped electrode is surrounded by a relatively low temperature synthetic resin, and the generated negative ions do not come into contact with the high-temperature member, so that the negative ions do not break down and efficiently reach the hair. Efficient.

  According to the hair iron of the present invention described above, since the grip does not change during curling or straight, switching can be performed without changing, and the hair set by switching can be smoothly transferred.
