Specifically, at first, the radius of curvature of flexure plane (hair clamping face lateral bending curved surface) 32d and the radius of curvature of flexure plane (curled portion lateral bending curved surface) 3e are set as setting.Then, the width W that makes flexure plane 32d and flexure plane 3e, namely from flexure plane 32d with the tabular surface 32b continuous section that arranges continuously to the width W (with reference to Fig. 5) of the outboard end (outermost end of curled portion 3d) of flexure plane 3e under constant state, suitably mobile flexure plane 32d and flexure plane 3e obtain the maximum of the contact area of the hair H under this radius of curvature condition.Then, survey out the slip load value of this moment.
Then, the combination of the radius of curvature of the radius of curvature of flexure plane 32d and flexure plane 3e is changed to other combinations, carry out and above-mentioned same operation.
Like this, obtain the contact area of hair H and the relation between the slip load value, thereby, obtain and utilizing upside hair clamping face 22a and downside hair clamping face 32a to clamp hair H and making hair H be attached between hair H under the state of curled portion 3d and flexure plane (hair clamping face lateral bending curved surface) 32d and the contact area between hair H flexure plane (curled portion lateral bending curved surface) 3e is radius of curvature more than setting, flexure plane (hair clamping face lateral bending curved surface) 32d and the radius of curvature of flexure plane (curled portion lateral bending curved surface) 3e.
Fig. 8 represents to make the radius of curvature of hair clamping face lateral bending curved surface changing between 0.5mm～1.5mm and making the radius of curvature of curled portion lateral bending curved surface at contact area and the slip load value of the hair H that changes between 0.5mm～1.5mm and obtain under each radius of curvature condition with the form of table.
Observe this Fig. 8, can be interpreted as, if increase the radius of curvature of hair clamping face lateral bending curved surface and the radius of curvature of curled portion lateral bending curved surface, the contact area of hair H increases, and the slip load value reduces.
In addition, in the present embodiment, be constant owing to making the width W between flexure plane 32d and flexure plane 3e, therefore, the measured value of hair contact area is equivalent to (hair contact area)/(width).
Like this, be constant by making the width W between flexure plane 32d and flexure plane 3e, the length that has suppressed the tabular surface of hair clamping face shortens and causes the conformal state effect of straight hair to reduce or the width of hair iron increases and the situation that causes hair iron to maximize.
That is, in the present embodiment, can seek the miniaturization of hair iron, and, the conformal state effect that can suppress straight hair reduces, and in addition, has obtained the radius of curvature of hair clamping face lateral bending curved surface of the conformal state effect that can improve curling shape and the radius of curvature of curled portion lateral bending curved surface.
And the slip loading rate of Fig. 8 is the value by (measured value of slip load)/(predetermined desirable slip load value) obtained.
In addition, the good load value of body sense when hair iron uses, slip load is generally approximately 300g～700g, has put down in writing the loading rate that respectively slides that desirable slip load value is made as 300g and obtains in Fig. 8.
Then, obtain the contact area of hair H and the relation between the slip load value according to Fig. 8, obtain coordinate diagram shown in Figure 9.
According to the coordinate diagram of this Fig. 9, if contact area is made as x, the slip load value is made as y, can judge that the pass between contact area and slip load value is to be similar to the result of obtaining by y=1013.2 * x-0.3851.
Then, obtain the slip load value and be the contact area of the upper limit 700g of the good load value of the body sense hair when following, as long as take contact area as this mode more than contact area set the radius of curvature of hair clamping face lateral bending curved surface and the radius of curvature of curled portion lateral bending curved surface, just can make the sliding of hair better.
And, because the good load value of body sense of slip load is about 300g～700g left and right, therefore, preferably the upper limit with the slip load value is set as 500g, sets the radius of curvature of hair clamping face lateral bending curved surface and the radius of curvature of curled portion lateral bending curved surface take the slip load value as the mode below it.
Specifically, according to Fig. 8, preferably making the radius of curvature of hair clamping face lateral bending curved surface is more than 0.5mm, and the radius of curvature that makes curled portion lateral bending curved surface is more than 2.0mm.
In the present embodiment, making the radius of curvature of hair clamping face lateral bending curved surface is 1.5mm, and the radius of curvature that makes curled portion lateral bending curved surface is 4.0mm.
And in the present embodiment, the surface roughness of the curled portion 3d of the curled portion 2d of clamping part 2b, clamping part 3b is less than the surface roughness of handle part 2a, handle part 3a.Specifically, the surface roughness of curled portion 2d, curled portion 3d is below 0.7 μ m, and the surface roughness of handle part 2a, handle part 3a is more than 1.6 μ m.Like this, be below 0.7 μ m by the surface roughness that makes curled portion 2d, curled portion 3d, can further improve the sliding of hair H.In addition, be more than 1.6 μ m by the surface roughness that makes handle part 2a, handle part 3a, the situation that can suppress to catch the hand of handle part to skid.
And, in the present embodiment, the position that clamping part 2b, clamping part 3b(is formed for curled portion 2d, curled portion 3d at least) form root side (is distolateral) undergauge on length direction from upside hair clamping face 22a and downside hair clamping face 32a (in the direction of utilizing upside hair clamping face 22a and downside hair clamping face 32a to clamp under the state of hair H, intersect with the bearing of trend of nipped hair H) to the cone-shaped of its tip side (another is distolateral).
Like this, form to the cone-shaped of length direction undergauge by the position that is formed with at least curled portion 2d, curled portion 3d with clamping part 2b, clamping part 3b, thereby easily hair H is applied helix-coil.
Want to apply this helix-coil, (top circumferential length) * 2＞(the root side circumferential length) that need to make the pass of top circumferential length and root circumferential length be.
Therefore, in the present embodiment, obtaining can be that the diameter of 50mm, root is 30mm(root circumferential length 30 * π mm at the width of regulation hair thread) time, implement the coning angle θ (with reference to Fig. 7) of helix-coil.
When coning angle θ became large, the top circumferential length shortened, and the top circumferential length is with respect to the ratio of root circumferential length diminish (with reference to Figure 10).
And Figure 11 represents the relation of coning angle θ and top circumferential length.In addition, the horizontal line a of Figure 11 represents the root circumferential length, and in the present embodiment, it is 30 * π (mm).
And the coordinate diagram of the top circumferential length the when thick line of inclination means the regulation coning angle according to this coordinate diagram, can be interpreted as, when coning angle was about 10 °, the top circumferential length was half of root circumferential length.
And the zone of can implement the condition of helix-coil, namely satisfying (top circumferential length) * 2＞(root side circumferential length) is the oblique line part of Figure 11.
According to above content, in the situation that the diameter that the width of regulation hair thread is 50mm, root is 30mm, as long as coning angle θ is made as 0 °＜θ≤10 °, just can effectively apply helix-coil.In the present embodiment, coning angle θ is about 1 °.
As mentioned above, in the present embodiment, to utilize upside hair clamping face 22a and a pair of hair clamping face of downside hair clamping face 32a() clamp hair H and make that hair H is attached under the state of curled portion 3d, between hair H and flexure plane (hair clamping face lateral bending curved surface) 32d and the contact area between hair H and flexure plane (curled portion lateral bending curved surface) 3e as the mode more than setting, set the radius of curvature of flexure plane 32d and the radius of curvature of flexure plane 3e.

With respect to this, in the present embodiment, when hair H is implemented the conformal state of curling shape, owing to having increased the contact area that reaches between hair H and flexure plane 32d between hair H and flexure plane 3e, therefore, the load of sliding can be reduced, thereby the sliding of the hair H when arranging hair can be improved.
And, adopt present embodiment, make can radius of curvature is larger flexure plane (hair clamping face lateral bending curved surface) 32d and the configuration that links smoothly of flexure plane (curled portion lateral bending curved surface) 3e, therefore, can make the local load that hair H is applied is not face load for linear load.As a result, can reduce the load of the locality that hair H is applied, and, the sliding of hair H can be improved, thereby the situation of hair H can be suppressed to damage.And, can suppress to be formed at because hair H being applied step-like folding line conformal that linear load easily produces the situation of hair H, therefore, can more easily hair H be organized into desired shape.
Like this, adopt present embodiment, can obtain to make the better hair iron 1 of sliding of hair H.
And, in the present embodiment, make the surface roughness of curled portion 3d of curled portion 2d, clamping part 3b of clamping part 2b less than the surface roughness of handle part 2a, handle part 3a.Therefore, can further improve the hair sliding, and, the situation that can suppress to catch the hand of handle part to skid.
And, in the present embodiment, the position that is formed with at least curled portion 2d, curled portion 3d of clamping part 2b, clamping part 3b is formed utilizing upside hair clamping face 22a and a pair of hair clamping face of downside hair clamping face 32a() clamp under the state of hair H, the cone-shaped from one distolateral (root side) undergauge on the length direction of clamping part 2b, clamping part 3b (direction of intersecting with the bearing of trend that is jammed hair H) to another distolateral (tip side).Therefore, can easilier apply helix-coil to hair H.
and, in the present embodiment, any one in upside hair clamping face (the 1st hair clamping face) 22a and downside hair clamping face (the 2nd hair clamping face) 32a (in the present embodiment for upside hair clamping face 22a) be positioned at clamping part 2b, side's side (rear) on the length direction of clamping part 3b (direction of intersecting with the bearing of trend of hair H) arranges jut (teat) 20c, and, any one in upside hair clamping face (the 1st hair clamping face) 22a and downside hair clamping face (the 2nd hair clamping face) 32a (in the present embodiment for upside hair clamping face 22a) be positioned at clamping part 2b, the opposing party's side (the place ahead) on the length direction of clamping part 3b (direction of intersecting with the bearing of trend of hair H) arranges jut (teat) 20c.Therefore, along the drop-down hair iron 1 of hair H the time, can utilize this teat 20c combing hair H.And the hair H that can suppress to be clamped by upside hair clamping face 22a and downside hair clamping face 32a breaks away from the zone of hair clamping face 22a, hair clamping face 32a or can't make hair H be attached to the situation of curled portion 3d.Like this, by jut (teat) 20c is set, can makes hair H hold together between jut (teat) 20c and combing hair H, thereby can make hair H curling more equably.
