As shown in Figure 3, rotating ring 10 forms the annular that has predetermined thickness a along the direction of rotary middle spindle C, outstanding on the side face being provided with locking protrusion 11 (fastener) within it, and on outer peripheral face outstanding the 1st lug boss 12 that is provided with.
And as Fig. 3 and shown in Figure 6, rotating ring 10 not only is configured in the circular depression 32 that is arranged at the main body right side housing 3Hr outside, and to be fitted to above-mentioned rotary middle spindle C from the bottom surface of this circular depression 32 be on the outside of the outstanding propeller boss 33 in center.At this moment, be provided with the gap of the degree that allows above-mentioned rotating ring 10 distortion at the rotating ring 10 and the fitting portion of propeller boss 33.
Peripheral part at propeller boss 33 is formed with slot 33a, is engaged among this slot 33a by the locking protrusion 11 with rotating ring 10, and rotating ring 10 is ended along the direction of rotation card with propeller boss 33, and then becomes one on direction of rotation with the connecting portion 31 of main part 3.
On the other hand, though ratchet ring 20 also can form as one with the lever right side housing 5Hr of lever 5, but this example is as shown in Figure 7, this ratchet ring 20 and lever right side housing 5Hr as respectively independently parts form, and form continuously annular around rotating ring 10 peripheries.And, in the end of rotary middle spindle C direction of the ratchet ring 20 that forms annular---promptly, with ratchet ring 20 bottom surface 21 is set with becoming one ringwise with the end of the inboard relative side of lever right side housing 5Hr.
In the ratchet ring 20 relative portion relative with the periphery of rotating ring 10---be on the inner peripheral surface of ratchet ring 20, be provided with the crimping of following with the 1st lug boss 12 of rotating ring 10 and cross the 2nd lug boss 22 freely mutually.At this moment, when the 1st lug boss 12 was crossed the 2nd lug boss 22, effect was towards load (reaction force) R (with reference to Figure 12) of center position on the 1st lug boss 12.
As shown in Figure 8, the 2nd lug boss 22 is made of two convex shaped lug boss 22a and ratchet lug boss 22b, the described couple of convex shaped lug boss 22a makes lever 5 stretch with respect to main part 3 that (with reference to Figure 10) accommodates central part with the 1st lug boss 12 when becoming user mode, described ratchet lug boss 22b be arranged on lever 5 with respect to this pair convex shaped lug boss 22a displacement only on the position of angle θ 1 (with reference to Figure 10).Angle θ 1 is slightly littler with respect to the maximum folded angle of main part than lever.At this moment, the ledge shape in the arc-shaped of two convex shaped lug boss 22a and ratchet lug boss 22b.
As shown in Figure 7, ratchet ring 20 has become the inboard of the lobe 51 that is configured in the setting of housing 5Hr upper end, lever right side.The center of lobe 51 is consistent with rotary middle spindle C, and heart position is formed with shoulder hole 52 therein.
As shown in Figure 7, on the bottom surface 21 of ratchet ring 20, be equipped with a plurality of (this example is in 6 places) along circumferentially spaced at interval snap fit tabs portion 23 about equally, and be provided with the closely depressed part 53 of chimeric these snap fit tabs portions 23 of a plurality of difference in the inboard of this lobe 51 towards lobe 51.
It is between a plurality of radial reinforcement 53c at center that depressed part 53 is arranged on rotary middle spindle C, and these reinforcements 53c is strengthened by the arc reinforcement 53d that with rotary middle spindle C is the center each other.So, inserting engaging in the depressed part 53 by snap fit tabs portion 23 with ratchet ring 20, ratchet ring 20 is ended along the direction of rotation card by lever right side housing 5Hr, and then becomes one on direction of rotation with lever 5.
At this moment, make in example of a part in a plurality of snap fit tabs portion 23 and make 2 23a of snap fit tabs portion that are positioned at the below higher a little highlightedly than other the 23b of snap fit tabs portion.By like this, assembling ratchet ring (Network イ Star Network リ Application グ) at 20 o'clock, at first the high 23a of snap fit tabs portion is inserted depressed part 53a as guiding, then the remaining snap fit tabs 23b of portion is inserted depressed part 53b, become easy by making whole snap fit tabs portion 23 is inserted like this.
And this example makes 2 23a of snap fit tabs portion that are positioned at the below horizontal wide more elongated than other the 23b of snap fit tabs portion, and the depressed part 53a of corresponding with it lobe 51 is also horizontal wide elongated than other depressed part 53b.By like this, when assembling ratchet ring 20,, therefore can become suitable position relation and assemble ratchet ring 20 (the 2nd lug boss is with respect to the position of the 1st lug boss) because the 23a of snap fit tabs portion of horizontal wide length can only insert among the corresponding with it depressed part 53a.
And as shown in Figure 6, in the both sides of the slot 33a of the propeller boss 33 of chimeric rotating ring 10, be formed with outwards outstanding jut 34 in this example.On the other hand, as shown in Figure 7 and Figure 8, on lobe 51 face relative, form a pair of lug boss 54 on the periphery that above-mentioned jut 34 is engaged to shoulder hole 52 on through the straight line at center with main body right side housing 3Hr.
So, when assembling main body right side housing 3Hr and lever right side housing 5Hr, in the propeller boss 33 that rotating ring 10 is assembled into main body right side housing 3Hr and after ratchet ring 20 being assembled in the lobe 51 of lever right side housing 5Hr, ratchet ring 20 is fitted to make on the periphery of rotating ring 10 this lobe 51 from the outside by circular depression 32 linings of main body right side housing 3Hr.By like this, main body right side housing 3Hr and lever right side housing 5Hr are assembled temporarily.
At this moment, the jut 34 of the propeller boss 33 of chimeric rotating ring 10 lays respectively among the 54a of arc-shaped recess portion between a pair of lug boss 54 that is formed on shoulder hole 52 circumferences, and by following the folding rotation of lever 5, jut 34 moves in the 54a of arc-shaped recess portion.So when lever 5 was in extended configuration, jut 34 withstood on in a pair of lug boss 54 one, and be bent when becoming folded state when lever 5, jut 34 withstands on in a pair of lug boss 54 another.Therefore, constitute the 1st inboard stop part S1 by these juts 34 and lug boss 54.
The following describes the assembling of main body left side housing 3Hl and lever left side housing 5Hl.As shown in Figure 4 and Figure 5, the outside, the bottom of the connecting portion 31 of housing 3Hl forms circular depression 35 on the left of main body, and in the upper end of lever left side housing 5Hl lobe 55 is set.Inboard at this lobe 55, with rotary middle spindle C is the prominent tubular axle 56 that is set to the shoulder hole 52 (with reference to Fig. 7) that reaches lever right side housing 5Hr in center, on the other hand, at the central part of the circular depression 35 of main body left side housing 3Hl, form on rotary middle spindle C that rotation freely fits tightly, the inserting hole 36 of chimeric tubular axle 56.
And, is the prominent a pair of fan-shaped lug boss 37 with predetermined angle theta 2 of establishing in center at the lateral surface of circular depression 35 with inserting hole 36, is that the center is provided with a pair of arc-shaped recess portion 57 of accommodating fan-shaped lug boss 37 with tubular axle 56 on the medial surface of lobe 55 simultaneously.
And as shown in Figure 5, tubular axle 56 being punctured into makes the lobe 55 of lever left side housing 5Hl by the outside lining of the circular depression 35 of main body left side housing 3Hl in the inserting hole 36.By finishing the interim assembling of main body left side housing 3Hl and lever left side housing 5Hl like this.Become the state of the top of tubular axle 56 this moment from the interior side-prominent scheduled volume of inserting hole 36.
And when lobe 55 was covered by circular depression 35, fan-shaped lug boss 37 was positioned at arc-shaped recess portion 57, and fan-shaped lug boss 37 follows the rotation of lever 5 to move in arc-shaped recess portion 57.And when lever 5 was in extended configuration and folded state, fan-shaped lug boss 37 withstood on respectively on the end walls 57a of arc-shaped recess portion 57, constituted the 2nd inboard stop part S2 by these fan-shaped lug bosses 37 and end walls 57a.
And as shown in Figure 4, circular-arc peristome 38 is formed at the bottom of the circular depression 35 of housing 3Hl on the left of main body, but on the part of these peristome 38 outer peripheral portions, is formed with notch 38a.On the other hand as shown in Figure 6, in the outstanding projection 39 that is provided with among the above-mentioned notch 38a of tight insertion in the lower end of the connecting portion 31 of main body right side housing 3Hr.
Then, with various functional parts---be that fan F, heater H, motor M, ion generating device I, the 1st to the 3rd switch 6,61,62 and power line 7 etc. are assembled into respectively between the interim like this main body right side housing 3Hr that has assembled and lever right side housing 5Hr and main body left side housing 3Hl and the lever left side housing 5Hl, then with main body right side housing 3Hr and the housing 3Hl butt joint of main body left side, and with lever right side housing 5Hr and the housing 5Hl butt joint of lever left side, the part combination that will dock respectively.
At this moment, as shown in Figure 9, the top of side-prominent tubular axle 56 is inserted into the shoulder hole 52 of lever right side housing 5Hr in the inserting hole 36 that main body left side housing 3Hl forms, (left among the figure) inserts hold-down screw (also can be bolt) among the centre bore 52b of end difference 52a from the outside in this state, tightens among the centre bore 56a that is fixed to tubular axle 56.Thus, main body right side housing 3Hr and lever right side housing 5Hr and main body left side housing 3Hl and lever left side housing 5Hl at connecting portion 4 by fastened to each other.
And when main body left side housing 3Hl was docked with main body right side housing 3Hr, the projection 39 of main body right side housing 3Hr closely was fitted among the notch part 38a of main body left side housing 3Hl, and the position of carrying out these two housing 3Hl, 3Hr bottom is involutory.
Assembled like this main part 3 and lever 5 can be connected between the extended configuration of lever 5 and the folded state by restraining mechanism 4 with relatively rotating.And along with main part 3 and lever 5 are that the center relatively rotates with restraining mechanism 4, rotating ring 10 is rotated by relative with ratchet ring 20.So, the 2nd lug boss 22 of the 1st lug boss 12 of rotating ring 10 and ratchet ring 20 (two convex shaped lug boss 22a and ratchet lug boss 22b) is followed crimping and is crossed mutually freely and move.
Promptly as shown in figure 10, when lever 5 is stretched, the 1st lug boss 12 is crossed the central part of protruding 22c between adjacent two convex shaped lug boss 22a of ratchet lug boss 22b one side of ratchet lug boss 22b and two convex shaped lug boss 22a, keeps the extended configuration of lever 5 in this state.The 1st stop part S1 and the 2nd stop part S2 also are in effective status under this extended configuration.
And as shown in figure 11, when the use of hair hair-dryer 1 is over when lever 5 folded up, the 1st lug boss 12 can be crossed ratchet lug boss 22b and obtain click (kowtow and the hit) sense of rattling away.At this moment, the 1st lug boss 12 is in the position of having crossed ratchet lug boss 22b, and the 1st stop part S1 and the 2nd stop part S2 work, and rotating ring 10 stops with the relative rotation of ratchet ring 20, and the folded state of lever 5 is held.
And the material that the lever right side housing 5Hr (lever 5) that ratchet ring 20 usefulness strength ratios are provided with it with becoming one in this example on direction of rotation is high forms.Promptly, though left and right side housing 3Hl, the 3Hr of main part 3 and left and right side housing 5Hl, the 5Hr of lever 5 with synthetic resin as global formations such as material use ejection formations, but also use at ratchet ring 20 under the situation of synthetic resin global formation, form this ratchet ring 20 with the strong synthetic resin material of the synthetic resin material of strength ratio lever 5.At this moment, though can use metal such as aluminium to form ratchet ring 20, be more satisfactory at the molding synthetic resin that working strength is high aspect processability and the cost.
And though ratchet ring 20 is being done as a whole being supported on the housing 5Hr of lever right side on the direction of rotation, as shown in Figure 9, this lever right side housing 5Hr is provided with the noncontact portion 58 that does not contact with the outside (periphery) of ratchet ring 20.Promptly, though ratchet ring 20 by as mentioned above snap fit tabs portion 23 is fitted in the inboard depressed parts 53 that are provided with of lobe 51 with lever right side housing 5Hr on direction of rotation by integrated, but this moment, the periphery of lobe 51 almost became a face ground to form noncontact portion 58 with the top end face of depressed part 53, the part that does not contact with the periphery of ratchet ring 20.
On the other hand, replace the noncontact portion 58 that ratchet ring 20 is set like this at the maintaining part 32a that the outside that keeps ratchet ring 20 is set on the housing 3Hr of main body right side on the housing 5Hr of lever right side in this example.This maintaining part 32a utilizes the circular depression 32 formed propeller boss 33, is formed by the periphery wall 32a of this circular depression 32.
And, this example as shown in Figure 10 and Figure 11, between main part 3 and lever 5, be provided be positioned at than ratchet ring 20 in the outer part, limit the folding stop part S3 that uses in these main parts 3 and the outside of the predetermined rotary state of lever 5.Should be folding with stop part S3 by the protuberance 40 that the lower end, front side of the lever connecting portion 31 of main part 3 is extended downwards again and the bearing 59 on being arranged on inside lever 5 rear sides constitute, become the block piece when having folded lever 5.
As Fig. 4 and shown in Figure 6, protuberance 40 cuts protuberance 40a, 40b as divided half point and is separately positioned on main body right side housing 3Hr and the main body left side housing 3Hl, make each half point cut protuberance 40a, 40b combination by these two housing 3Hr, 3Hl butt joints, form top ends and be circular-arc outstanding ligule protuberance 40.
On the other hand, as shown in Figure 7, bearing 59 is the trapezoidal rear side the inside that is arranged on lever right side housing 5Hr, cross section.At this moment, bearing 59 is formed the height with the degree of depth addition of the degree of depth of lever right side housing 5Hr and lever left side housing 5Hl.Thus, by two housings 5Hr, 5Hl are docked, bearing 59 is configured to traverse the inboard overall with of lever 5, when folding lever 5, can firmly block protuberance 40 by enough bearings 59.In addition as shown in Figure 1, the preceding upper lateral part of lever 5 becomes along the 5a of concave shape portion of the shape of protuberance 40.
In addition as shown in figure 10, under the state that lever 5 is stretched, the rear side upper end 5b of the rear side bottom 31a of connecting portion 31 and lever 5 connects, the stretching, extension stop part S4 in the outside when constituting lever 5 stretching, extensions by these rear side bottom 31a and rear side upper end 5b.
Wherein, this example as shown in figure 12, the part 10K that is provided with the 1st lug boss 12 of rotating ring 10 forms thicklyer at radially wall thickness t2 than other parts 10N at radially wall thickness t1, t1＞t2.Therefore that is, on wall thickness t1, t2, have poorly, make the circle that is shaped as, and make the action direction that is shaped as load R (above-below direction among the figure) be the elliptical shape of minor axis along interior week along rotating ring 10 peripheries owing to make like this.
And,, be provided with locking protrusion 11 as the holding section of being ended by the slot 33a card of the propeller boss 33 that is provided with on the main part 3 in the inboard of the part 10N of the wall thickness t2 of rotating ring 10 attenuation.At this moment, the 1st lug boss 12 and locking protrusion 11 are separately positioned on a plurality of places of the circumferencial direction of rotating ring 10.
Promptly, not only the 1st lug boss 12 is being set in this example, and locking protrusion 11 is being set in 2 places that are the approximate right angle configuration with respect to this straight line L1 through on the straight line L2 at rotating ring 10 centers through 2 places on the straight line L1 at the center of rotating ring 10.Certainly, two convex shaped lug boss 22a that constituted the 2nd lug boss 22 this moment and ratchet lug boss 22b corresponding with a pair of the 1st lug boss 12 and respectively dispose respectively a pair of, and the slot 33a of propeller boss 33 also with locking protrusion 11 corresponding being formed on through 2 places on the straight line at center.
By adopting above structure, if adopt the hair dryers 1 of this example, when be fixed on the main part 3 rotating ring 10 be fixed on lever 5 on ratchet ring 20 relative rotations, when the 1st lug boss 12 of rotating ring 10 and the 2nd lug boss 22 of ratchet ring 20 were crossed mutually, the load R that is produced by the crimping of these the 1st lug bosses 12 and the 2nd lug boss 22 was transfused to rotating ring 10.
At this moment, in this example, owing to make the wall thickness t1 radially of the part 10K that is provided with the 1st lug boss 12 of rotating ring 10 thicker at radially wall thickness t2 than other parts 10N, therefore improved intensity at the part 10K that its wall thickness has been thickened, can make the repulsion increase of rotating ring 10.
Promptly be interpreted as, as shown in figure 13, making wall thickness is under the situation of rotating ring 100 of almost certain prior art, found 10R and the 10P that stress is concentrated respectively in the inboard of the part 10K that is provided with the 1st lug boss 12 and near be provided with the part 10N of locking protrusion 11 the outside, under the situation of the rotating ring 10 of this example, thicken the intensity of the part 10K of wall thickness t1 by raising, as shown in figure 14, reduced the stress that concentrating on this 10R and 10P part.
Therefore, even under the situation that rotating ring 10 is out of shape by alternating bending when each lever 5 folds, the material of rotating ring 10 need not be changed over the high material of rigidity and just can suppress this tired repeatedly rotating ring 10 that causes by plastic deformation.Thus can enough materials same as the prior art, by same processing---for example ejection formation etc. forms rotating ring 10, therefore the formation of rotating ring 10 is become easily, and can suppress to produce on the lever 5 and become flexible.
And, if adopt this example, owing to be provided with the locking protrusion 11 on the propeller boss 33 that is used for these rotating ring 10 cards being ended at main part 3 in the inboard of the part 10N of the wall thickness t2 of rotating ring 10 attenuation along direction of rotation, though the stress that produces when therefore load R acts on the rotating ring 10 concentrates on the part 10N of wall thickness t2 attenuation, this stress can be supported by propeller boss 33 by fastener.Thus, can suppress rotating ring 10, can guarantee the original function that the 1st lug boss 12 and the 2nd lug boss 22 produce by the bigger distortion of load R---promptly guarantee the maintenance of lever 5 and produce the click sense of rattling away.
And, if adopt this example, owing to be provided with the 1st lug boss 12 and locking protrusion 11 in a plurality of places that make progress in the week of rotating ring 10 respectively, therefore the place that can shorten the place of load R effect and bearing stress is at the interval that makes progress in week, so can further suppress the distortion of rotating ring 10.
And, if adopt this example, because each 2 place on each self-corresponding straight line L1, the L2 at the center of passing through rotating ring 10 are provided with the 1st lug boss 12 and locking protrusion 11 respectively, so the place of load R effect is positioned at the relative position, center that clips rotating ring 10 with the place that stress is concentrated.Thus, these load R and stress are cancelled each other on the ring-shaped continuous part of rotating ring 10, owing to suppressed to act on the eccentric force on the rotating ring 10---be about to the power that rotating ring 10 is pushed a side of propeller boss 33 to, therefore can improve supporting with main part 3 these rotating rings 10 of supporting.
Though preferred example of the present invention more than has been described, but the present invention is not limited to above-mentioned example, in the scope that does not exceed aim of the present invention, can carry out various changes, for example, though above-mentioned example is poor for the part 10K that is provided with the 1st lug boss 12 is existed at radially wall thickness t2 at radially wall thickness t1 and other parts 10N, make the circle that is shaped as along rotating ring 10 peripheries, and make the action direction that is shaped as load R (above-below direction among the figure) be the ellipticity of minor axis along interior week, but shown in also can the variation of image pattern 15 like that, make the circle that is shaped as, make the ellipticity that is shaped as along periphery along interior week of rotating ring 10A.
And, though the 2nd lug boss 22 of ratchet ring in the above-mentioned example (Network イ Star Network リ Application グ) 20 is by when becoming lever 5 into user mode with respect to main part 3 stretching, extensions, the 1st lug boss 12 is accommodated two convex shaped lug boss 22a of central part, and the locational ratchet lug boss 22b that has been arranged on respect to this pair convex shaped lug boss 22a displacement with folding angle θ 1 equal angles of lever 5 constitutes, but also can be as Figure 16 and variation shown in Figure 17, two convex shaped lug boss 22a are set on the position of ratchet lug boss 22b, on use location and these two positions, folding position, sandwich the 1st lug boss 12 ground and support.
And,, also can form semicircle for example and wait other shape though above-mentioned example forms annular with rotating ring 10.
And, though above-mentioned example is arranged on rotating ring 10 on the main part 3 integratedly along direction of rotation, and ratchet ring 20 is arranged on the lever 5 integratedly along direction of rotation, but also their relation can be turned around, rotating ring 10 is arranged on lever 5 one sides, ratchet ring 20 is arranged on main part 3 one sides.
And, though in above-mentioned example, hair care devices has been described,, can both use the present invention so long as the lever that can fold is connected to the hair care devices on the main part with hair nursing function as hair dryers 1.
