Description

【０００１】
【発明の属する技術分野】
この発明は、剃刀ヘッドとこれを首振り可能に支持するホルダとを備えた首振り式剃刀に関するものである。
【０００２】
【従来の技術】
従来、例えば特開平１１ー１５６０６８号公報にかかる首振り式剃刀においては、ホルダの頭部を構成する上側カバー体と下側カバー体との間で両支持アームや操作部やプッシャや弾性体などの各部品が組み込まれ、両支持アームが上側カバー体の前端部と下側カバー体の前端部との間の案内通路を通して前方へ突出している。
【０００３】
【発明が解決しようとする課題】
上記案内通路の間隔は、両支持アームが開閉動方向を含む面に対し直交する方向へ振れることを抑えて両支持アームの開閉動作を円滑に行なう上で重要である。しかも、剃刀ヘッドはこの両支持アームで支持されるので、剃刀ヘッドの振れを抑えて良好な剃り味を得るためにも適切な間隔に設定する必要がある。しかし、上記案内通路は互いに組み付けられた上側カバー体と下側カバー体との間で形成されるので、それらの組付状態ごとに案内通路の間隔が変わったり、組付け当初は適切な間隔に設定してあっても使用により間隔が変わるおそれがあった。
【０００４】
また、両支持アームや操作部やプッシャや弾性体などの各部品をそれぞれ別々に上側カバー体と下側カバー体との間に組み込まねばならないので、その部品組付作業が面倒であった。
【０００５】
本発明は、第一に上記案内通路を適切な間隔に設定することを目的にし、第二にホルダにおける部品組付作業を簡単にすることを目的にしている。
【０００６】
【課題を解決するための手段及び発明の効果】
後記実施形態の図面（図１〜８）の符号を援用して本発明を説明する。
請求項１の発明にかかる首振り式剃刀は、下記のように構成されている。
【０００７】
この首振り式剃刀は、剃刀ヘッド（１）とこれを首振り可能に支持するホルダ（２）とを備えている。前記ホルダ（２）は互いに分離された部品組付体（３）と下側カバー体（４）と上側カバー体（５）とからなる。この下側カバー体（４）及び上側カバー体（５）はそれぞれ把持部（４ａ，５ａ）と頭部（４ｂ，５ｂ）とからなる。この部品組付体（３）はこの下側カバー体（４）の頭部（４ｂ）と上側カバー体（５）の頭部（５ｂ）との間に嵌め込まれて組み付けられている。前記部品組付体（３）は互いに組み付けられた取付台（６）と左右両支持アーム（７）と操作部（８）とプッシャ（９）と弾性体（１０）とを有している。前記下側カバー体（４）と上側カバー体（５）との間とこの下側カバー体（４）及び上側カバー体（５）とこの部品組付体（３）の取付台（６）との間でそれぞれ互いに位置決めし得る係止部（１１ａ，１１ｂ，１２ａ，１２ｂ，１３ａ，１３ｂ，１４ａ，１４ｂ）を設けている。前記部品組付体（３）において、左右両支持アーム（７）は取付台（６）上の左右両側に形成した支軸部（１８）に対し回動支持部（１９）で挿嵌されて取付台（６）上に回動可能に支持されるとともに取付台（６）の前端部左右両側から突出する状態で互いに開閉動する。操作部（８）は左右両支持アーム（７）間の取付台（６）上で取付台（６）に対し移動可能に支持されている。プッシャ（９）は左右両支持アーム（７）間の取付台（６）上で操作部（８）及び取付台（６）に対し移動可能に支持されて取付台（６）の前端部から突出している。弾性体（１０）は左右両支持アーム（７）間の取付台（６）上でプッシャ（９）と操作部（８）との間に支持されてプッシャ（９）と操作部（８）とを互いに離間させる。操作部（８）の移動により左右両支持アーム（７）を開閉動させて前記剃刀ヘッド（１）の左右両支持部（２７）に対し左右両支持アーム（７）の支持部（７ａ）を係脱可能にするとともに、左右両支持アーム（７）の支持部（７ａ）に対しこの剃刀ヘッド（１）の左右両支持部（２７）を支持してプッシャ（９）をこの剃刀ヘッド（１）の押圧面（２６）に対し弾性体（１０）の付勢力により圧接させている。前記部品組付体（３）の取付台（６）の前端部は前記下側カバー体（４）の前端部と上側カバー体（５）の前端部との間で挟持されている。その取付台（６）の前端部左右両側には前記左右両支持アーム（７）が挿入される案内溝（２２）を取付台（６）と一体的に設けている。この左右両案内溝（２２）において、この左右両支持アーム（７）の回動軌跡の方向を含む面（Ｓ）に対し直交する上下方向の両側に設けた上下両案内壁部（２３，２４）の相対向案内面（２３ａ，２４ａ）間の間隔（Ｗ）を一定に設定するとともにその上下両案内面（２３ａ，２４ａ）間に案内通路（２５）を設けている。この案内通路（２５）は、この左右両支持アーム（７）の回動軌跡の方向の両側のうち、左右両支持アーム（７）が互いに開動する向き側へ開放されているとともに、左右両支持アーム（７）が互いに閉動する向き側へ閉塞されている。この案内通路（２５）でこの左右両支持アーム（７）が開閉動する際、上側案内壁部（２３）の案内面（２３ａ）が左右両支持アーム（７）の上方側への動きを規制するとともに、下側案内壁部（２４）の案内面（２４ａ）が左右両支持アーム（７）の下方側への動きを規制する。
【０００８】
そのため、案内通路（２５）において上下両案内面（２３ａ，２４ａ）間の間隔（Ｗ）を容易かつ適切に設定することができる。従って、左右両支持アーム（７）の振れを抑えてその開閉動作を円滑に行なうことができるとともに、剃刀ヘッド（１）の振れを抑えて良好な剃り味を得ることができる。
【００１０】
また、左右両支持アーム（７）や操作部（８）やプッシャ（９）や弾性体（１０）などの各部品をまず取付台（６）上で一括して組み付けて部品組付体（３）とした後に、この部品組付体（３）をホルダ（２）の頭部（４ｂ，５ｂ）に組み付けることができる。従って、ホルダ（２）における部品組付作業を簡単にすることができる。さらに、下側カバー体（４）と上側カバー体（５）と部品組付体（３）との間の相互位置決めを確実にして組付誤差を防ぐことができる。
【００１７】
【発明の実施の形態】
以下、本発明の一実施形態にかかる首振り式剃刀を図面を参照して説明する。
＜首振り式剃刀の概要＞
首振り式剃刀は、図７（ａ）及び図８（ａ）に示すように、剃刀ヘッド１とこれを首振り可能に支持するホルダ２とを備えている。このホルダ２は、図１に示す部品組付体３と、図２に示す下側カバー体４と、図３に示す上側カバー体５とからなる。この部品組付体３と下側カバー体４と上側カバー体５とは、互いに分離し得る。この部品組付体３は、後で詳述するように、取付台６と両支持アーム７と内側操作部８とプッシャ９と弾性体１０（圧縮コイルばね）とを有している。この下側カバー体４及び上側カバー体５はそれぞれ把持部４ａ，５ａと頭部４ｂ，５ｂとからなる。
【００１８】
図４（図１，２参照）に示すように、前記下側カバー体４の頭部４ｂの内側に前記部品組付体３が嵌め込まれて組み付けられる。この組付状態では、この部品組付体３の取付台６の前端部左右両側に形成された係止凹部１１ａ（係止部）と、この下側カバー体４の頭部４ｂの前端部左右両側に形成された係止凸部１１ｂ（係止部）とが互いに係合されるとともに、この部品組付体３の取付台６の後端部側に形成された係止板部１２ａ（係止部）と、この下側カバー体４の頭部４ｂの後端部側に形成された係止板部１２ｂ（係止部）とが互いに係合され、下側カバー体４の頭部４ｂに部品組付体３が合致して位置決めされる。
【００１９】
図５（図１〜３参照）に示すように、図４に示す状態でさらに前記上側カバー体５を前記下側カバー体４に重ねると、この下側カバー体４の頭部４ｂの内側とこの上側カバー体５の頭部５ｂの内側との間に前記部品組付体３が嵌め込まれて組み付けられる。この組付状態では、この部品組付体３の取付台６の後端部側に形成された係止突起１３ａ（係止部）と、この上側カバー体５の頭部５ｂの後端部側に形成された係止孔部１３ｂ（係止部）とが互いに係合されるとともに、この下側カバー体４の後端部側に形成された係止突起１４ａ（係止部）と、この上側カバー体５の頭部５ｂの後端部側に形成された係止孔部１４ｂ（係止部）とが互いに係合され、下側カバー体４の頭部４ｂ及び上側カバー体５の頭部５ｂに部品組付体３が合致して位置決めされる。
【００２０】
図６（図１〜３参照）に示すように、図５に示す状態でさらに前記上側カバー体５の頭部５ｂの外側から外側操作部１５をこの頭部５ｂに重ねると、前記部品組付体３の内側操作部８に形成された両係止孔部１６ａ（係止部）と、この外側操作部１５に形成された両係止突起１６ｂ（係止部）とが操作孔５ｃを通して互いに係合され、この内側操作部８と外側操作部１５とが一体的に結合されて一つの操作部１７が形成される。
【００２１】
＜前記部品組付体３及びそれとの関連構成＞
図１，７，８に示す部品組付体３は、前述したように、取付台６と両支持アーム７と内側操作部８とプッシャ９と弾性体１０（圧縮コイルばね）とを有し、それらが互いに組み付けられている。内側操作部８は、取付台６に対し前記外側操作部１５とともに前後方向へ移動し得るように支持されている。プッシャ９は、内側操作部８の前側で内側操作部８及び取付台６に対し前後方向へ移動可能に支持されている。弾性体１０はプッシャ９と内側操作部８との間で支持され、弾性体１０の付勢力により、プッシャ９と内側操作部８とが互いに離間して、プッシャ９が取付台６の前端部から前方へ突出して静止しているとともに、内側操作部８が後退して非操作位置で静止している。内側操作部８の左右両側で取付台６に支軸部１８が形成されている。両支持アーム７は回動支持部１９でこの両支軸部１８に挿嵌されて回動可能に支持され、この両回動支持部１９から突設された連動凸部２０（連動部）と、内側操作部８の左右両側に形成された連動凹部２１（連動部）とが互いに係合されている。
【００２２】
前記部品組付体３の取付台６の前端部は前記下側カバー体４の前端部と上側カバー体５の前端部との間で挟持されている。その取付台６の前端部左右両側には前記左右両支持アーム７が挿入される案内溝２２が取付台６と一体的に形成されている。この左右両案内溝２２は、この左右両支持アーム７の回動軌跡の方向を含む面Ｓに沿って延び、その面Ｓに対し直交する上下方向の両側にそれぞれ案内壁部２３，２４を有している。この上下両案内壁部２３，２４の相対向案内面２３ａ，２４ａ間の間隔がＷ（一定）に設定され、その上下両案内面２３ａ，２４ａ間には案内通路２５が設けられている。この案内通路２５は、この左右両支持アーム７の回動軌跡の方向の両側のうち、左右両支持アーム７が互いに開動する向き側へ開放されているとともに、左右両支持アーム７が互いに閉動する向き側へ閉塞されている。この案内通路２５でこの左右両支持アーム７が開閉動する際、上側案内壁部２３の案内面２３ａが左右両支持アーム７の上方側への動きを規制するとともに、下側案内壁部２４の案内面２４ａが左右両支持アーム７の下方側への動きを規制する。
【００２３】
図６に示すように前記剃刀ヘッド１をホルダ２から分離した状態において前記操作部１７で外側操作部１５に指を当てがって内側操作部８を前後方向へ移動させると、その動きは両連動凹部２１と両連動凸部２０とを介して内側操作部８から両支持アーム７に伝わり、両支持アーム７はこの両案内面２３ａ，２４ａ間にある案内通路２５で開閉動し得る。
【００２４】
図７に示すように、プッシャ９の頭部９ａが剃刀ヘッド１の押圧面２６に当てがわれた状態で、後退位置にある操作部１７により両支持アーム７が閉動し、両支持アーム７の支持突部７ａ（支持部）が剃刀ヘッド１の両支持孔２７（支持部）に係入されている。プッシャ９は弾性体１０により付勢されて剃刀ヘッド１を圧接する。この圧接状態で、剃刀ヘッド１は静止位置を取る。剃刀ヘッド１に使用時の力が加わると、剃刀ヘッド１は、プッシャ９による圧接力に抗して両支持アーム７の支持突部７ａを中心に回動し、その静止位置を基準にして傾動する。
【００２５】
図７に示す状態から、操作部１７を弾性体１０の付勢力に抗して前進位置へ移動させると、図８に示すように両支持アーム７が開動し、両支持アーム７の支持突部７ａが剃刀ヘッド１の両支持孔２７から離脱する。そのため、剃刀ヘッド１は両支持アーム７から分離される。その後、操作部１７を離すと、操作部１７が弾性体１０の付勢力により後退位置に戻り、前述した図７に示す状態となる。

BACKGROUND OF THE INVENTION
The present invention relates to a swing-type razor including a razor head and a holder that supports the razor head so that the head can swing.
[0002]
[Prior art]
Conventionally, for example, in a swing-type razor according to Japanese Patent Application Laid-Open No. 11-156068, both support arms, an operation unit, a pusher, an elastic body, etc. are provided between an upper cover body and a lower cover body constituting the head of the holder. These parts are incorporated, and both support arms protrude forward through a guide passage between the front end portion of the upper cover body and the front end portion of the lower cover body.
[0003]
[Problems to be solved by the invention]
The distance between the guide passages is important for smoothly opening and closing the support arms by suppressing the swing of the support arms in a direction perpendicular to the plane including the opening and closing direction. In addition, since the razor head is supported by both the supporting arms, it is necessary to set an appropriate interval in order to suppress the shake of the razor head and obtain a good shaving taste. However, since the guide passage is formed between the upper cover body and the lower cover body assembled with each other, the interval between the guide passages changes depending on the assembly state, or at an appropriate interval at the beginning of assembly. Even if it was set, there was a risk that the interval would change depending on use.
[0004]
In addition, since the parts such as the support arms, the operation unit, the pusher, and the elastic body have to be separately assembled between the upper cover body and the lower cover body, the parts assembling work is troublesome.
[0005]
The object of the present invention is firstly to set the guide passages at appropriate intervals, and secondly to simplify the part assembling work in the holder.
