【0014】 請求項1記載のヘアアイロンは、第1アーム(1)と、第2アーム(2)と、上記第1アーム(1)と第2アーム(2)を根元側で開閉可能にヒンジ連結するヒンジ部(3)とを備えている。上記ヒンジ部(3)は、第1部材(10)と第2部材(20)と連結ユニット(30)とを含んで構成されている。上記第1部材(10)は上記第1アーム(1)側に取り付けられ、上記第2部材(20)は、上記第2アーム(2)側に取り付けられる。そして、上記連結ユニット(30)は、上記第1部材(10)と第2部材(20)を連結する。 このような構造では、上記第1部材(10)、上記第2部材(20)および上記連結ユニット(30)から構成される上記ヒンジ部(3)は、上記第1アーム(1)および上記第2アーム(2)とは異なるユニットである。このため、開閉支点となるヒンジ部(3)と上記第1アーム(1)および上記第2アーム(2)の先端側に設けられる電熱部(50)の間で樹脂に収縮や反りが生じたとしても、上記第1アーム(1)と上記第2アーム(2)とは別ユニットの上記ヒンジ部(3)で調節が可能で、電熱部(50)同士がうまく面接触し、設計通りに挟んだ毛髪全体を加熱する性能を引き出すことができる。また、上記ヒンジ部(3)が上記第1アーム(1)および上記第2アーム(2)と交換可能となるため、長期間の使用により上記ヒンジ部(3)が摩耗等による損傷を生じた場合にはヒンジ部(3)だけを交換してヘアアイロンを使用し続けることができる。つまり、従来の軸部が一体で構成されているヘアアイロンでは、経年使用による摩耗等でガタツキが生じ性能が低下した際にはアーム全体を交換する必要があった。本発明では、上記第1アーム(1)および上記第2アーム(2)に対して上記ヒンジ部(3)を分離して交換可能とすることにより、上記第1アーム(1)および上記第2アーム(2)を構成する主要な部材を廃棄することなく上記ヒンジ部(3)のみの交換で機能(初期性能)を回復し、最小限の部品交換で製品寿命を延ばすことが可能となった。このように、まだまだ使える部材の廃棄を防止して資源の無駄を防ぎ、コスト面で有利であるだけでなく、循環型社会の実現にも貢献する。

Abstract

This hair iron improves the precision of the arm, including the opening / closing pivot point and the heating element, and enhances the contact of the heating element to ensure that the entire strand of hair is heated. [Solution] The device comprises a first arm (1), a second arm (2), and a hinge part (3) that hinges the first arm (1) and the second arm (2) so that they can be opened and closed at the base. The hinge portion (3) is composed of a first member (10) attached to the first arm (1), a second member (20) attached to the second arm (2), and a connecting unit (30) that connects the first member (10) and the second member (20). Since the hinge portion (3) is a different unit from the first arm (1) and the second arm (2), even if shrinkage or warping occurs in the resin between the hinge portion (3), which serves as the opening and closing pivot point, and the heating element (50) provided at the tip, adjustment is possible, and the heating elements (50) make good surface contact with each other.
