BACKGROUND OF THE INVENTION
The present invention relates to a curling iron. More specifically, it is used by practitioners such as hairdressers at beauty salons to perform retouching and nuance processing, such as performing a straight perm treatment on the customer's hair and then lightly curling the tip of the hair. About curling irons.
[0002]
[Prior art]
An example of this type of curling iron is described in Japanese Patent Application Laid-Open No. 10-113212. As shown in FIG. 6, the curling iron includes a grip portion 101, a rod-like or cylindrical winding drum (heater portion) 102 fixed and connected so as to protrude from the tip, and an outer peripheral surface of the winding drum. A clip (press plate) 103 that sandwiches the hair therebetween and a heater provided in the winding drum 102 are provided. A water tank 104 filled with water for steam is provided at the tip of the winding drum 102 so as to be movable in the axial direction. The water tank 104 is a hollow container having a truncated cone shape.
[0003]
When this curl iron is used, for example, the grip part 101 is gripped with the right hand, the clip 103 is opened and closed with the finger of the gripping hand, and the root side of the hair slice is sandwiched between the winding body 102 and the clip 103, and the hair Slide toward the front. Next, follow the hair tip along the winding drum 102 with a comb, rotate the grip 101 while aligning the hair tip with the fingertip of the left hand, and wind the hair tip at a predetermined angle according to the design to obtain a preferred curl design Perform nuance processing. In that case, the curl iron may be stabilized by picking the water tank 104 with the left hand.
[0004]
[Problems to be solved by the invention]
In the curl iron, since the grip portion 101 is fixed to the winding drum 102, the grip drum 101 is rotated to rotate the winding drum 102. However, when the grip part 101 is slid in the hand and rotated, the winding drum 102 is not stable. Although the water tank 104 can be picked with the left hand and rotated while the posture is stabilized, it is difficult to perform a delicate winding operation and fine adjustment of the rotation angle.
[0005]
On the other hand, since the above-described curling iron is a steam type, it has a water tank 104 filled with water at the tip. However, a curling iron without a steam tank cannot pick up the tip of the winding drum. Further, even if a knob is provided with a heat insulating material at the tip of the winding drum 102, heat from the roll is transmitted and the temperature rises immediately, so that it cannot be firmly picked.
[0006]
An object of the present invention is to provide a curl iron that improves the usability of the conventional curl iron and can be rotated so that the rotation axis does not shake. Furthermore, this invention makes it a technical subject to provide the curl iron which can support a front end side firmly, when it does not have a water tank.
[0007]
[Means for Solving the Problems]
A curling iron of the present invention (Claim 1) includes a main body, a cylindrical roll extending from one end of the main body and containing a heater therein, a press plate having an arcuate cross section for sandwiching hair in the roll, A holder provided rotatably around the main body, and a cap made of a material having a plurality of ribs on the surface and having low thermal conductivity, which is fixed to the tip of the roll. Such a curling iron is preferably provided with a rotary knob that can be rotated by picking it with a fingertip of a hand holding the holder at a site adjacent to the holder of the main body (Claim 2).
[0008]
The cap has a base portion fixed to the roll, a cylindrical portion extending from the base portion toward the distal end side, and a plurality of annular shapes that are arranged at intervals around the cylindrical portion and have a diameter that gradually decreases toward the distal end. What consists of a rib is preferable (Claim 3). Further, among the annular ribs, it is preferable that a step larger than the step between the other annular ribs is provided between the first annular rib closest to the base and the other annular rib. Further, among the annular ribs, it is preferable that the outer peripheral surfaces of the plurality of annular ribs excluding the first annular rib have a conical surface as a whole (Claim 5). Further, it is preferable that the main body includes a cylindrical portion, and the holder is a thin-walled cylindrical member that is rotatably provided on an outer periphery of the cylindrical portion.
[0009]
[Operation and effect of the invention]
In the curling iron of the present invention (Claim 1), since the holder is rotatably provided around the main body, the main body can be firmly held through the holder, and the main body can be rotated inside the palm. Can do. Therefore, the roll fixed to the main body can be rotated. Therefore, it is possible to rotate the roll so that the rotation axis is not shaken while stably holding the curling iron. Moreover, since the main body and the holder are separate bodies, heat is not transmitted from the main body to the holder. Furthermore, the cap fixed to the tip of the roll protects the inside of the roll and can be used as a knob. That is, since there are ribs around the cap, the heat dissipation action is high. Moreover, since the contact area between the finger and the cap is small and the thermal conductivity is low, heat is not easily transmitted from the cap to the finger. Therefore, the cap can be firmly picked with the fingertip of the hand opposite to the hand holding the holder, and the roll can be rotated at an accurate angle without feeling heat by rotating the cap.
[0010]
In a curl iron (Claim 2) in which a rotary knob that can be picked and rotated by a fingertip of a hand holding the holder is provided at a portion adjacent to the holder of the main body. The main body and the roll can be rotated with the fingertips of the hands while stabilizing. At that time, a holder is interposed between the main body and the palm, and the rotary knob is simply picked with a finger, so that heat is not transmitted to the palm or the finger.
[0011]
The cap has a base portion fixed to the roll, a cylindrical portion extending from the base portion toward the distal end side, and a plurality of annular shapes arranged in a spaced manner around the cylindrical portion and having a diameter decreasing toward the distal end. In a curling iron (claim 3) comprising ribs, some of the meat inside the fingers bites into the annular rib. Therefore, it is difficult to slide in the axial direction. Moreover, the plurality of annular ribs are easy to pick because the tip side has a small diameter. And, coupled with the low heat dissipation and thermal conductivity of the ribs, the cap can be gripped more firmly.
[0012]
In the curl iron (Claim 4), a step larger than the step between the other annular ribs is provided between the first annular rib closest to the base and the other annular ribs among the annular ribs. The finger can be picked with the tip of the finger pressed against the first annular rib. Therefore, the tip side of the curling iron can be more securely held without feeling heat. Further, when the finger is picked without being pressed against the first annular rib, even if the finger slides to the proximal end side, it stops at the first annular rib, so that force can be applied toward the roll side with confidence. Further, among the annular ribs, when the outer peripheral surface of the plurality of annular ribs excluding the first rib presents a conical surface as a whole (Claim 5), the step when the outer peripheral surface of the annular rib is picked. There is little feeling and it is easier to pick.

A curling iron 10 shown in FIGS. 1 and 2 includes a main body 11, a cylindrical roll 12 extending from one end of the main body, an arc-shaped press plate 13 for sandwiching hair in the roll, and the periphery of the main body 11. A thin-walled cylindrical holder 14 provided rotatably and a cap 15 made of a material having low thermal conductivity, which is fixed to the tip of the roll 12. A known heater (not shown) is accommodated in the roll 12.
[0015]
As shown in FIG. 3, the main body 11 is a cylindrical member. A cylindrical portion 21 in which the holder 14 is rotatably provided around the main body 11, and a rotary knob 22 having a large diameter provided on the tip side (left side) of the cylindrical portion. And a somewhat tapered rear end portion 23 provided on the rear end side of the cylindrical portion. A stopper 24 for preventing the holder 14 from coming off is placed around the rear end 23 and fixed with screws or the like. In this embodiment, the main body 11 is made of a synthetic resin that is molded in a vertically divided form, and the upper half 11a and the lower half 11b are integrated with a screw. The rear end side is fixed by the stopper 24, and the leading end side is fitted and fixed, so that the integrity is high. The material of the main body 11 is a synthetic resin having low thermal conductivity, high heat resistance, and high slipperiness, but may be other materials such as metal. A reinforcing material 25 such as a metal may be embedded in the synthetic resin material.
[0016]
The holder 14 is a thin cylindrical member formed of synthetic resin or the like, and the rear end side is provided with an annular protrusion 26 that gently expands as a slipper. Large diameter step portions 27 are provided on the inner surface of the front end portion and the inner surface of the rear end portion of the holder 14. An annular spacer 28 is interposed between the stepped portion 27 and the outer peripheral surface of the cylindrical portion 21 of the main body 11. This spacer 28 is interposed between the holder 14 and the main body 11 in order to obtain a smooth rotation even when distortion or sink marks occur when the main body 11 or the holder 14 is molded. Further, a material having good moldability, for example, a synthetic resin material such as engineering plastic is preferable. Such a material is preferable in terms of low thermal conductivity, but may be composed of a metal material. The spacer 28 on the rear end side is interposed between the step portion of the holder 14 and the stopper 24, and restrains the movement of the holder 14 in the axial direction together with the stopper 24. In addition, there is an effect of improving the slipperiness between the holder 14 and the stopper 24. The stopper 24 is formed in a cup shape from a synthetic resin or the like, and is screwed to the main body with two upper and lower screws.
[0017]
Returning to FIG. 1, the rotary knob 22 provided on the distal end side of the main body 11 is provided with a plurality of anti-slip concave grooves 22 a around the rotary knob 22. The rotary knob 22 is a part of the main body 11 and does not rotate with respect to the main body 11. Further, a volume dial 29 for adjusting the temperature of the heater is rotatably provided around the axis extending in the radial direction with respect to the rotary knob 22. The distal end portion 30 of the main body 11 has a somewhat small cylindrical shape in order to fit and fix the end portion of the roll 12. As shown in FIG. 3, the inside of the main body 11 is a cavity, and a control mechanism including a temperature regulator and a timer that are adjusted by the volume dial 29 is accommodated therein. And the power supply line connected with those electric components is extended to the fixed terminal N1 of the well-known rotation connector N accommodated in the rear-end part 23. FIG. A rotary terminal N2 that is rotatably connected to the fixed terminal passes through the opening of the rear end portion 23 and the stopper 24, and a power cord that connects a plug is connected to the other end.
[0018]
The roll 12 is a thick cylindrical member formed by extrusion molding or the like from a material having high thermal conductivity, for example, a metal such as aluminum. The surface of the roll 12 is preferably provided with a ceramic coat for protecting the roll surface and protecting hair. Furthermore, by providing a ceramic coat, the slipping property is in an appropriate range, and the hair (particularly damaged hair) is not caught and is not slipped too much. Furthermore, due to the far-infrared effect, heat is sufficiently transferred to the inside of the hair and further to the second volume of hair. Instead of ceramic coating, surface treatment such as fluororesin (Teflon (registered trademark)) processing (improvement of slipperiness) or alumite treatment (far infrared effect) may be applied.
[0019]
A plurality of dovetails 31 extending in the axial direction are formed on the outer peripheral surface of the roll 12. A guard 32 is fitted in the dovetails 31. The guard 32 covers the surface of the roll 12 so as not to feel much heat even when it hits the skin of a permanent treatment person or a person to be treated. The guard 32 is a known saddle-shaped member composed of a plurality of vertical bars 33 fitted in the respective dovetail grooves 31 and a plurality of arc-shaped members 34 extending in the circumferential direction to connect them. It is. Since the vertical bar 33 is accommodated in the dovetail 31 of the roll 12, there is no problem when winding the hair. The guard 32 is made of a material having low thermal conductivity such as a synthetic resin.
[0020]
A heater is accommodated in the roll 12, and the heater is connected to the controller by an electric wire. The heater is fixed in the roll 12 with a support (not shown) made of an electrically insulating material, and a thin cylindrical electrical insulating member is interposed between the heater and the inner surface of the roll 12.
[0021]
The press plate 13 includes a plate portion 36 having an arcuate cross section that is in contact with the surface of the roll 12, and a lever 37 for rotatably connecting the base end of the plate portion 36 to the main body 11. Has been. The lever 37 includes a U-shaped support arm 38 straddling the left and right sides of the main body 11 and an operation arm 39 protruding from the upper end of the support arm 38 at a predetermined angle with respect to the plate portion 36. The plate portion 36 is basically made of a material having high thermal conductivity and high strength such as a metal plate. The lever 37 is made of a synthetic resin having a low thermal conductivity. A plurality of guard arcuate members 40 similar to those of the roll 12 are also provided on the surface of the plate portion 36.
[0022]
As shown in FIG. 4, the cap has a base 41 fitted and fixed to the tip of the roll 12, a cylinder 42 extending from the cap to the tip, and a plurality of caps arranged at intervals around the cylinder. It is composed of a single annular rib 43. The intervals between the annular ribs 43 are substantially equal. The base portion 41 includes a bottomed cylindrical cylindrical portion 44 that is fitted to the inner surface of the roll 12 and screwed, and a flange portion 45 that is fitted to the end edge and the outer surface of the roll 12. The tip of the cylinder part 42 is open.
[0023]
Among the annular ribs 43, the outer diameter of the first annular rib 43a closest to the base is substantially the same as that of the flange portion 45, and a large step K is provided between the second annular rib 43b. . And the outer peripheral surface of the annular ribs 43b, 43c, 43d excluding the first annular rib presents one conical surface S as a whole. It can also be seen that a plurality of annular grooves 46 are formed on the surface of the truncated cone-shaped cap. The diameter of the first annular rib 43a greatly exceeds the conical surface S thereof. Therefore, when the practitioner picks the second to fourth annular ribs 43b to 43d with the finger of the left hand, the tip of the finger comes into contact with the first annular rib 43a and does not touch the relatively high temperature flange portion 45. Therefore, it can be operated with peace of mind. Further, by shortening the annular rib 43 toward the tip, the rigidity is increased and it is difficult to break when dropped. In addition, the conical shape makes it easy to insert a hair iron into the separated hair from the tip.
[0024]
The outer peripheral surface of the cylindrical portion 43 is a conical surface S2 whose tip angle is steeper than the conical surface S formed by the outer periphery of the second to fourth annular ribs 43b to 43d. Thereby, the height decreases in the order of the second annular rib 43b, the third annular rib 43c, and the fourth annular rib 43d. Thereby, while maintaining the rigidity of the annular rib to some extent, the closer to the roll 12, the higher the height of the annular rib and the greater the heat dissipation action. However, the surface of the cylinder part 43 can also be cylindrical. Moreover, since the front-end | tip of the cylinder part 42 is open | released, heat does not accumulate inside, and the heat dissipation action is high. However, in some cases, it may be a closed configuration.
[0025]
Next, a method of using the curling iron 10 configured as described above will be described. The curling iron 10 is provided with a so-called retouch or nuance that forms a loose wave or curl on the hair end in order to give a sense of volume and style after processing a straight perm. Therefore, a straight perm is applied to the subject's hair in advance. The heater of the curling iron 10 is energized before the treatment, and the roller 12 is heated to a predetermined temperature. In this state, the practitioner holds the holder 14 with the right hand, for example, and pushes the tip of the operation arm 39 with the thumb or index finger of the gripping hand to open the press plate 13.
[0026]
Then, the base side of the hair slice separated by the left-hand comb is sandwiched between the roll 12 and the press plate 13. Then slide it towards the hair end. At that time, the cap 15 is picked with a free fingertip of the left hand holding the comb 50 and can be slid while the direction of the curling iron is stabilized. In that case, since the cap 15 is composed of a plurality of annular ribs 43, the heat of the roll 12 is not easily transmitted to the cap 15, and the heat is not felt.
[0027]
Then, the hair tip protruding from the press plate 13 is followed by the comb 50 of the left hand so as to follow the roll 12, and the rotary knob 22 is picked and rotated by the thumb and index finger of the right hand as shown in FIG. At that time, the roll 12 can be rotated while holding the cap 15 with the fingertip of the left hand L. Even in that case, you can feel safe because you don't feel the heat. Since the palm of the right hand R and other fingers firmly hold the holder 14, the rotation axis of the curling iron 10 is not shaken, and the roll 12 can be rotated in a stable state. Moreover, since the thumb and index finger of the right hand can be used freely, the number of rotations or the rotation angle can be finely adjusted.
[0028]
With the sliced hair sandwiched between the roll 12 and the press plate 13 as described above, the hair is curled or waved by rotating it by a predetermined angle while adjusting the tension applied to the hair slightly. As a result, retouching or nuance processing is performed. Note that the slice width and rotation angle vary depending on the hair section, the slice width is increased in the over section (upper layer of the hair) and the rotation angle is about 0 to half rotation, and the slice width is slightly increased in the middle section. The rotation angle is about one rotation, and in the under section, the slice width is made thin and the rotation angle is about one and a half to two and a half rotations.
[0029]
As described above, the curl iron 10 has the thin cylindrical holder 14 rotatably fitted to the outer periphery of the main body 11, so that the volume of the cavity in the main body 11 is sufficiently maintained, and the roll 12 and The main body 11 can be configured to be rotatable. Since the rotary knob 22 can be accurately rotated by the thumb and the index finger while firmly grasping the main body 11 via the holder 14, a fine adjustment of the rotation angle is possible. Furthermore, since the temperature of the cap 15 at the tip does not rise, the posture of the curling iron 10 can be stabilized by being held by fingers of other hands.
[0030]
In the above-described embodiment, the annular ribs 43 of the cap 15 are arranged at regular intervals. However, even in this case, the diameter of each annular rib 43 is preferably set so that the outer peripheral surface is arranged in a substantially conical shape except for the first annular rib 43a. In addition, the outer peripheral surfaces of the second to fourth annular ribs 43b to 43d are formed in a conical surface shape, but may be a cylindrical surface parallel to the axis, and the cross-section of each annular rib is an arc shape. The finger contact may be softened.
