Description

この発明は、カールヘアーなどをするのに用いられるヘアーアイロンに関するものである。 The present invention relates to a hair iron used for curling hair and the like.

髪をふんわりと大きめのカールにアレンジしたいときなどに用いるものとしてヘアーアイロンがある。 There is a hair iron that is used when you want to arrange your hair softly into larger curls.

このタイプのヘアーアイロンは、例えば図３に示す本願発明のヘアーアイロンと同様に、ハンドル１０と直列に筒状の発熱部１１を設け、その発熱部１１にクリップ１２を設けた構造となっており、前記クリップ１２で毛束を挟んで発熱部１１に巻きつけ、巻きつけた状態を数秒間保持してカールするというものである。 This type of hair iron has a structure in which, for example, a cylindrical heat generating portion 11 is provided in series with the handle 10 and a clip 12 is provided on the heat generating portion 11 as in the case of the present invention shown in FIG. The clip 12 sandwiches the hair bundle and winds it around the heat generating portion 11, and the curled state is held for several seconds to curl.

そして、この髪を巻きつける際に、巻き付けやすいように、発熱部１１の先端にキャップ部材２０を取り付け、前記キャップ部材２０とハンドル１０とを左右の手で支持することにより、ヘアーアイロンを回転させやすいようにしている。 And when winding this hair, the cap member 20 is attached to the front-end | tip of the heat generating part 11 so that winding may be easy, and the hair iron is rotated by supporting the said cap member 20 and the handle | steering-wheel 10 with a right and left hand. Easy to use.

従来、この発熱部１１の先端のキャップ部材２０は、図６の（特許文献１）のように、ネジ止めするようにしていた。すなわち、図６では、発熱部１１の先端にキャップ部材１を嵌合し、嵌合したキャップ部材１を発熱部１１の左右からネジ１４を挿通してネジ止めするという方法が用いられていた。
特開２００３−２８４６０８号公報 Conventionally, the cap member 20 at the tip of the heat generating portion 11 is screwed as shown in FIG. 6 (Patent Document 1). That is, in FIG. 6, a method is used in which the cap member 1 is fitted to the tip of the heat generating portion 11, and the fitted cap member 1 is screwed by inserting screws 14 from the left and right of the heat generating portion 11.
JP 2003-284608 A

しかしながら、上記のネジ止め方法では、キャップ部材をネジ止めするためには、キャップ部材を発熱部の先端に嵌入し、発熱部の先端に対向して設けたネジ止め用の貫通孔と、キャップ部材に形成したネジ孔とを合致させたのち、ネジを挿通して螺合しなければならない。また、そのネジ止めも一箇所ずつ止めなければならないので、取り付け作業が非常に煩雑で、しかも、ネジの取り付け忘れや締め忘れなどのミスも起こしやすいので、生産効率も悪いという問題がある。 However, in the screwing method described above, in order to screw the cap member, the cap member is fitted into the tip of the heat generating part, and a screwing through hole provided facing the tip of the heat generating part is provided. After matching the screw holes formed in, the screws must be inserted and screwed together. Further, since the screws must be fixed one by one, the installation work is very complicated, and mistakes such as forgetting to attach or forgetting the screws are likely to occur, resulting in poor production efficiency.

そこで、この発明の課題は、取り付け作業を簡単に行えるようにすることである。 Accordingly, an object of the present invention is to make it possible to easily perform the attaching operation.

上記の課題を解決するため、この発明では、筒状の発熱部の先端に嵌入されるキャップ部材が、中央に貫通孔を設けた嵌合部材と、その上部に取り付けられるつまみ部材を備え、前記嵌合部材の周囲から突出させた先端を嵌入方向に対して後方へ傾斜させた突片を設け、前記突片が突片を放射状に設けた中心に孔を形成した係合部材からなり、前記係合部材の孔から嵌合部材の貫通孔にネジを挿通し、嵌合部材から突出したネジにスプリングを挿通してつまみ部材にネジ止めし、その際、つまみ部材が回転するように締め付け、組み立てたキャップ部材の嵌合部材側を嵌入方向として筒状の発熱部の先端に嵌入して、嵌合部材の周囲から突出した突片を筒状の発熱部の内壁に係合させるようにした構成を採用したのである。 In order to solve the above problems, in the present invention, a cap member that is fitted into the tip of the cylindrical heat generating portion includes a fitting member that has a through hole in the center, and a knob member that is attached to the top thereof, Providing a projecting piece with the tip projecting from the periphery of the fitting member inclined backward with respect to the fitting direction, the projecting piece is made of an engaging member having a hole formed in the center provided with the projecting piece radially, Insert a screw from the hole of the engaging member into the through hole of the fitting member, insert a spring through the screw protruding from the fitting member, and screw it to the knob member. At that time, tighten the knob member to rotate, the fitting member side of the assembled cap member as fitted direction and fitted into the distal end of the tubular heating unit, so as to engage the projecting piece projecting from the periphery of the fitting member to the inner wall of the cylindrical heat generating portion The configuration was adopted.

このような構成を採用したことにより、キャップ部材の嵌合部を筒状の発熱部の先端に嵌合すると、前記嵌合部の突片は、嵌入方向に対して後方に傾斜しているので、嵌入を妨げない。また、嵌入後は、キャップ部材が外れようとして嵌入方向と逆方向へ動こうとすると、嵌入方向に対して後方に傾斜させた前記突片の先端が、筒状の発熱部の内壁に係合して抜け落ちを防止する。したがって、このようなキャップ部材を発熱部の先端へ嵌入するだけでキャップ部材の取り付けが完了する。 By adopting such a configuration, when the fitting portion of the cap member is fitted to the tip of the cylindrical heat generating portion, the protruding piece of the fitting portion is inclined backward with respect to the fitting direction. , Does not hinder insertion. Further, after the insertion, when the cap member is about to come off and tries to move in the direction opposite to the insertion direction, the tip of the protruding piece inclined rearward with respect to the insertion direction is engaged with the inner wall of the cylindrical heating portion. To prevent omissions. Therefore, the attachment of the cap member is completed simply by inserting such a cap member into the tip of the heat generating portion.

このとき、上記嵌合部の周囲から突出する突片を放射状に設けた中心に孔を形成した係合部材で構成し、前記係合部材の孔にネジを挿通して、挿通したネジを上記キャップ部材にネジ止めして、そのネジ止めした係合部材の突片がキャップの嵌合部の周囲から突出させたことにより、係合部材をネジ止めすることで、突片付きのキャップ部材を構成できる。 At this time, the projecting piece protruding from the periphery of the fitting portion is configured by an engaging member formed with a hole in the center, and a screw is inserted into the hole of the engaging member. screwed into the cap member, by protrusion of the screw was engaging member is protruded from the periphery of the fitting portion of the cap, by screwing the engaging member constituting the cap member with protrusion it can.

また、ネジ止めした係合部材は、キャップ部材の嵌入時には、係合部材の突片が、嵌入方向に対して後方に傾斜しているので嵌入を妨げない。また、嵌入後の前記突片は、嵌入方向に対して後方に傾斜した前記突片の先端が筒状の発熱部の内壁に係合して抜け落ちを防止する。 Further, when the cap member is fitted , the screwed engaging member does not hinder the fitting because the protruding piece of the engaging member is inclined rearward with respect to the fitting direction. In addition, the projecting piece after the insertion is prevented from falling out by engaging the tip of the projecting piece inclined rearward with respect to the fitting direction with the inner wall of the cylindrical heat generating portion.

また、このとき、上記キャップ部材が、嵌合部材とその上部に取り付けられるつまみ部材を備え、前記つまみ部を、上記係合部材から嵌合部に挿通したネジに、スプリングを介してネジ止めした構成を採用したことにより、係合部材の取り付けられたキャップ部材は、筒状の発熱部への嵌入時は、係合部材の突片が、嵌入方向に対して後方に傾斜しているので嵌入を妨げない。 Further, at this time, the cap member includes a fitting member and a knob member attached to the upper portion thereof, and the knob portion is screwed to a screw inserted from the engagement member into the fitting portion via a spring. By adopting the configuration, the cap member to which the engagement member is attached is inserted when the protrusion of the engagement member is inclined rearward with respect to the insertion direction when the cap member is inserted into the cylindrical heat generating portion. Not disturb.

また、前記発熱部へ嵌入後の前記突片は、嵌入方向に対して後方に傾斜した前記突片の先端が筒状の発熱部の内壁に係合して抜け落ちを防止する。また、嵌入後は、嵌合部に挿通したネジに挿通されたスプリングは、嵌合部からネジ止めされたつまみ部を浮かせるように付勢して嵌合部の摩擦を少なくして回動できるようにする。 In addition, the projecting piece after being inserted into the heat generating portion is prevented from falling off by the tip of the projecting piece inclined rearward with respect to the inserting direction being engaged with the inner wall of the cylindrical heat generating portion. In addition, after insertion, the spring inserted into the screw inserted into the fitting portion can be urged to lift the knob portion screwed from the fitting portion to rotate with less friction of the fitting portion. Like that.

この発明は、以上のように構成したことにより、キャップ部材を嵌入するだけで、発熱部材の先端に取り付けることができるので、組み立て作業が簡便で、しかも、ネジの取り付け忘れや締め忘れなどのミスも起きないので、生産効率も高くなる。 Since the present invention is configured as described above, it can be attached to the tip of the heat generating member simply by inserting the cap member, so that the assembling work is simple and the mistake such as forgetting to attach or forget to tighten the screw. Production will also increase.

以下、この発明を実施するための最良の形態を図面に基づいて説明する。
図１に、この形態のヘアーアイロンのキャップ部材２０の分解斜視図を示す。前記キャップ部材２０は、嵌合部材２１とつまみ部材２２とを備え、前記つまみ部材２２を係合部材２３からホルダー２４を介して嵌合部材２１に挿通したネジ２５に、スプリング２６を挿通してネジ止めした構造となっている。 The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows an exploded perspective view of the cap member 20 of the hair iron of this embodiment. The cap member 20 includes a fitting member 21 and a knob member 22, and a spring 26 is inserted through a screw 25 that is inserted into the fitting member 21 from the engaging member 23 through the holder 24. It has a screwed structure.

この形態のつまみ部材２２は、図１に示すように、円錐形に凹部２７を設けてツマミ形に形成したもので、前記凹部２７を指先で摘めるようにしたものである。また、つまみ部材２２の内部は中空にして、その中央に突起２８を設けてネジ溝を形成し、ネジ止めができるようにしてある。 As shown in FIG. 1, the knob member 22 in this form is formed in a cone shape by providing a concave portion 27 so that the concave portion 27 can be picked up with a fingertip. Further, the inside of the knob member 22 is hollow, and a projection 28 is provided at the center thereof to form a screw groove so that the screw can be fixed.

嵌合部材２１は、難燃性の樹脂を成型したもので、図１のように円筒形の基部２９の上部に、基部２９よりも大径に形成した鍔部３０を設けた形状となっている。 The fitting member 21 is formed by molding a flame-retardant resin, and has a shape in which a flange portion 30 having a larger diameter than the base portion 29 is provided on the upper portion of the cylindrical base portion 29 as shown in FIG. Yes.

すなわち、前記基部２９の外径を後述する発熱部１１の内径とほぼ同じ径（少し小さめの方が嵌め易い）に形成し、鍔部３０の外径を前記発熱部１１の外径と同じにしてある。また、その鍔部３０の中央には、円筒形の突部３１を形成し、その突部の中央に貫通孔３２を設けた形状となっている。 That is, the outer diameter of the base portion 29 is formed to be substantially the same as the inner diameter of the heat generating portion 11 described later (a slightly smaller one is easier to fit), and the outer diameter of the flange portion 30 is made the same as the outer diameter of the heat generating portion 11. It is. In addition, a cylindrical protrusion 31 is formed at the center of the collar part 30 and a through hole 32 is provided at the center of the protrusion.

一方、円筒形の基部２９の周囲には、この形態では、３本の溝３３が等間隔で設けてあり、係合部材２３を取り付けるようになっている。また、基部２９の内側に図１の符号３４のような突起を設けて係合部材２３を取り付ける際に仮止めできるようにしてある。 On the other hand, around this cylindrical base 29, in this embodiment, three grooves 33 are provided at equal intervals, and the engaging member 23 is attached. Further, a protrusion such as 34 in FIG. 1 is provided on the inner side of the base 29 so that it can be temporarily fixed when the engaging member 23 is attached.

係合部材２３は、ここでは、円板の周囲に３本の突片３５を放射状に設け、その円板の中心に孔３６を設けたもので、前記突片３５の幅と基部２９の溝３３の幅とが合致するように形成し、かつ、円板の外径を前記基部２９の内径に合致するように形成して、前記基部２９に取り付けられる形状としている。また、放射状に形成した３本の突片３５の先端を同方向に傾斜させて、基部２９に取り付けた際に、嵌入方向に対して後方に傾斜するようにしてある。 Here, the engaging member 23 is formed by radially providing three projecting pieces 35 around the disc and providing a hole 36 at the center of the disc. The engaging member 23 has a width of the projecting piece 35 and a groove in the base 29. The outer diameter of the disc is formed so as to match the inner diameter of the base 29, and is configured to be attached to the base 29. Further, the tips of the three projecting pieces 35 formed radially are inclined in the same direction, and when attached to the base 29, they are inclined backward with respect to the insertion direction.

また、この取り付けた際に、係合部材２３の円板の孔３６は、嵌合部材２１の貫通孔３２と合致する。この合致した孔３６には、先に述べたようにホルダー２４を嵌めてネジ２５を挿通する。 In addition, the disc hole 36 of the engagement member 23 matches the through hole 32 of the fitting member 21 when the attachment is performed. As described above, the holder 24 is fitted in the matched hole 36 and the screw 25 is inserted.

このとき、前記ホルダー２４には、図１に示すような軸にネジ２５の挿通孔３７を形成した「Ｔ」字型のものを使用して、図２（ａ）のように、端部に形成した鍔３８が係合部材２３の円板部分に当接して取り付けられるようにしている。 At this time, as the holder 24, a "T" -shaped one having an insertion hole 37 of the screw 25 formed on the shaft as shown in FIG. 1 is used, and as shown in FIG. The formed collar 38 is attached so as to come into contact with the disk portion of the engaging member 23.

この形態は、上記のように構成されており、この形態のヘアーアイロンでは、以下のように組み立てることにより、嵌合部材２１の周囲から突片３５を突出させたキャップ部材２０を図３のように、筒状の発熱部１１の先端に取り付ける。 This form is configured as described above. In the hair iron of this form, the cap member 20 in which the projecting pieces 35 protrude from the periphery of the fitting member 21 is assembled as shown in FIG. Next, it is attached to the tip of the cylindrical heat generating part 11.

すなわち、キャップ部材２０は、図１のように、例えば、嵌合部材２１の基部２９に係合部材２３を取り付け、ホルダー２４を嵌めてネジ２５を挿通し、挿通したネジ２５を嵌合部材２１の鍔部３０から突出させたのち、その突出したネジ軸にスプリング２６を挿通して、つまみ部材２２をネジ止めする。 That is, as shown in FIG. 1, for example, the cap member 20 has an engaging member 23 attached to the base 29 of the fitting member 21, the holder 24 is fitted, the screw 25 is inserted, and the inserted screw 25 is inserted into the fitting member 21. Then, the spring 26 is inserted through the protruding screw shaft, and the knob member 22 is screwed.

このネジ止めの際には、つまみ部材２２が回転するように遊びを設けて締め付ける。このように、遊びを設けてもつまみ部材２２は、スプリング２６のテンションによりネジ２５との係合が緩むことはない。 At the time of this screwing, play is provided and tightened so that the knob member 22 rotates. Thus, even if play is provided, the knob member 22 does not loosen the engagement with the screw 25 due to the tension of the spring 26.

こうして組み立てられたキャップ部材２０は、嵌合部材２１側を嵌入方向として筒状の発熱部１１の先端に嵌入する。このとき、嵌合部材２１から突出した突片３５は、嵌入方向に対して後方に傾斜しているので嵌入を妨げない。また、嵌入後は、キャップ部材２０が外れようとして嵌入方向と逆方向へ動こうとすると、図２（ａ）及び（ｂ）に示すように、嵌入方向に対して後方に傾斜させた前記突片３５の先端が、筒状の発熱部１１の内壁に係合して抜け落ちを防止する。 The cap member 20 assembled in this way is fitted into the tip of the cylindrical heat generating part 11 with the fitting member 21 side as the fitting direction. At this time, the projecting piece 35 protruding from the fitting member 21 is inclined rearward with respect to the fitting direction, and therefore does not hinder the fitting. Further, after the insertion, when the cap member 20 is about to come off and moves in the direction opposite to the insertion direction, as shown in FIGS. 2 (a) and (b), the protrusion inclined backward with respect to the insertion direction is shown. The tip of the piece 35 engages with the inner wall of the cylindrical heat generating part 11 to prevent it from falling off.

このように、嵌合部材２１の周囲から突片３５を突出させたキャップ部材２０を嵌入するだけで、キャップ部材２０の取り付けが完了する。 Thus, the attachment of the cap member 20 is completed only by inserting the cap member 20 in which the protruding piece 35 is protruded from the periphery of the fitting member 21.

したがって、組み立て作業が簡便で、しかも、ネジ２５の取り付け忘れや締め忘れなどのミスも起きないので、生産効率も高くなる。 Therefore, the assembling work is simple, and no mistakes such as forgetting to attach or tighten the screw 25 occur, so that the production efficiency is increased.

なお、この形態では、係合部材２３は、３本の突片３５を持つものとしたが、これに限定されるものではなく、必要な係止力に合わせてその数は適宜決めることができる。また、係合部材２３は、金属製でも良いが、強度が許せば樹脂製でも構わない。 In this embodiment, the engaging member 23 has the three projecting pieces 35. However, the present invention is not limited to this, and the number of the engaging member 23 can be appropriately determined according to the required locking force. . Further, the engaging member 23 may be made of metal, but may be made of resin if the strength permits.

また、このキャップ部材２０の取り付けられた図３に示すようなヘアーアイロンでは、一方の手でハンドル１０を持ったのち、クリップ１２で髪を挟み、他方の手で先端のキャップ部材２０のつまみ部材２２を摘んでハンドル１０を回転して発熱部１１に髪を巻きつける。その際、ハンドル１０を回転しても、つまみ部材２２はスプリング２６で付勢されて嵌合部材２１との摩擦が減少させてあるので、つまみ部材２２と一緒にネジ２５が回転して（ホルダー２４も摩擦の減少に関与するはずである）、ハンドル１０と一緒に回転しない。そのため、つまみ部材２２をハンドル１０の回転に合わせて、持ち直す必要がなく、ヘアーアイロンを安定して操作できるので、セットの仕上げも良好にできる。 Further, in the hair iron as shown in FIG. 3 to which the cap member 20 is attached, after holding the handle 10 with one hand, the clip 12 holds the hair, and the other hand holds the handle member of the cap member 20 at the tip. 22 is picked and the handle 10 is rotated to wind the hair around the heat generating portion 11. At this time, even if the handle 10 is rotated, the knob member 22 is urged by the spring 26 to reduce the friction with the fitting member 21, so that the screw 25 rotates together with the knob member 22 (holder). 24 should also be involved in friction reduction) and does not rotate with the handle 10. Therefore, it is not necessary to hold the knob member 22 in accordance with the rotation of the handle 10, and the hair iron can be stably operated, so that the finish of the set can be improved.

この実施例１に示すヘアーアイロンは、図４（ａ）、（ｂ）に示すように、つまみ部材２２と嵌合部材２１とが一体となったもので、先の形態のキャップ部材２０のようにつまみ部材２２が回転しないものである。 As shown in FIGS. 4 (a) and 4 (b), the hair iron shown in the first embodiment is one in which the knob member 22 and the fitting member 21 are integrated, and like the cap member 20 of the previous form. Further, the knob member 22 does not rotate.

また、このキャップ部材２０の嵌合部材２１の形状は、先の形態の基部２９の形状と同じで、３本の溝３３が等間隔に設けられたものである。また、嵌合部材２１の軸部分には、貫通孔に代えてネジ孔が設けられており、係合部材２３をネジ止めするようになっている。前記係合部材２３は、先の形態と同様に、中心に孔を設けた円板の周囲に３本の突片３５を放射状に設けたもので、基部２９に取り付けられたのち、突片３５は嵌合部材２１の周囲から突出する。 Further, the shape of the fitting member 21 of the cap member 20 is the same as the shape of the base portion 29 of the previous form, and three grooves 33 are provided at equal intervals. Further, a screw hole is provided in the shaft portion of the fitting member 21 instead of the through hole, and the engagement member 23 is screwed. The engaging member 23 is provided with three projecting pieces 35 radially around a disc having a hole in the center, as in the previous embodiment. Protrudes from the periphery of the fitting member 21.

この形態は、上記のように構成されており、キャップ部材２０を発熱部１１の先端に嵌合する部分の構成と作用効果については先の形態と同じなので、同一部材に同一符号を付して説明は省略する。 This configuration is configured as described above, and the configuration and the operational effect of the portion where the cap member 20 is fitted to the tip of the heat generating portion 11 are the same as the previous configuration, so the same members are denoted by the same reference numerals. Description is omitted.

なお、この実施例１では、キャップ部材２０と係合部材２３とを別体としたが、係合部材２３に代えて突片３５を一体に樹脂成型したものでも構わないことは当然である。 In the first embodiment, the cap member 20 and the engaging member 23 are separated from each other. However, it is a matter of course that the protruding piece 35 may be integrally molded with resin instead of the engaging member 23.

この実施例２は、この発明で使用されるヘアーアイロンの円筒状の発熱部１１の形状の他の態様を示したものである。 Example 2 shows another embodiment of the shape of the cylindrical heat generating portion 11 of the hair iron used in the present invention.

例えば、図５（ａ）、（ｂ）、（ｃ）に示すように、三角や半楕円形状など髪を巻きつけやすい形状であればどのようなものにも使用可能である。 For example, as shown in FIGS. 5 (a), 5 (b), and 5 (c), any shape can be used as long as it is easy to wind hair such as a triangle or a semi-elliptical shape.

このとき、キャップ部材２０の形状も発熱部１１の断面形状に合わせることは勿論である。また、キャップ部材２０の突片３５の数も形状に合わせて、より高い係止力が得られるように適宜決めることは勿論である。 At this time, of course, the shape of the cap member 20 is also matched to the cross-sectional shape of the heat generating portion 11. Of course, the number of the projecting pieces 35 of the cap member 20 is appropriately determined according to the shape so that a higher locking force can be obtained.
