Description

本発明は首振り式剃刀に関するものである。   The present invention relates to a swing-type razor.

下記特許文献1では、ホルダ2の頭部4b,5bに剃刀ヘッド1を首振り可能に支持する部品組付体3を組み付けた首振り式剃刀が開示されている。
特開2001−340671号公報
In the following Patent Document 1, a swing-type razor in which a component assembly 3 that supports the razor head 1 so as to be able to swing is mounted on the heads 4b and 5b of the holder 2 is disclosed.
JP 2001-340671 A

上記特許文献1は下記の問題点*を有する。
* ホルダ2の頭部4b,5bは互いに分離された一対のカバー体4,5からなり、部品組付体3は互いに重合されて取着されたこの両カバー体4,5間に組み付けられている。部品組付体3の係止突起13aと上側カバー体5の頭部5bの係止孔部13bとを互いに係合するとともに、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を合致させることにより、部品組付体3を両カバー体4,5の頭部4b,5b間に挟着して位置決めしているだけである。そのため、頭部4b,5b間で部品組付体3の緩みが生じるおそれがあり、部品組付体3をホルダ2の頭部4b,5bに対し確実に連結することができなくなる。
The patent document 1 has the following problem *.
* The heads 4b and 5b of the holder 2 are composed of a pair of cover bodies 4 and 5 separated from each other, and the component assembly 3 is assembled between the cover bodies 4 and 5 that are superposed and attached to each other. Yes. The locking protrusion 13a of the component assembly 3 and the locking hole 13b of the head 5b of the upper cover 5 are engaged with each other, and the head 4b of the lower cover 4 and the head of the upper cover 5 are engaged. By aligning the component assembly 3 with 5b, the component assembly 3 is simply sandwiched between the heads 4b, 5b of the cover bodies 4, 5 and positioned. Therefore, there is a possibility that the component assembly 3 is loosened between the heads 4 b and 5 b, and the component assembly 3 cannot be reliably connected to the heads 4 b and 5 b of the holder 2.

* 部品組付体3においては、両カバー体4,5の頭部4b,5b間で操作部17とプッシャ9とが操作部17の移動方向に沿って並び、弾性体10がこの操作部17とプッシャ9との間に介在されている。この操作部17は内側操作部8と外側操作部15とからなり、外側操作部15は操作部17の移動方向に対し直交する上方へ両頭部4b,5b間から露出している。そのため、部品組付体3を組み付けた頭部4b,5bにおいてそれらの組付構造が複雑になるとともに、操作部17によりプッシャ9を確実に押すことができなくなる。   * In the component assembly 3, the operation unit 17 and the pusher 9 are arranged along the moving direction of the operation unit 17 between the heads 4 b and 5 b of both cover bodies 4 and 5, and the elastic body 10 is the operation unit 17. And the pusher 9. The operation unit 17 includes an inner operation unit 8 and an outer operation unit 15, and the outer operation unit 15 is exposed from between both heads 4 b and 5 b upward in the direction orthogonal to the moving direction of the operation unit 17. Therefore, in the heads 4b and 5b to which the component assembly 3 is assembled, the assembly structure thereof becomes complicated, and the pusher 9 cannot be reliably pushed by the operation unit 17.

* 前記外側操作部15を不用意に押して剃刀ヘド1を両支持アーム7から離脱させるおそれがあった。
* 前記外側操作部15を押して両支持アーム7を互いに開いた支持解除状態で両支持アーム7に剃刀ヘッド1を当てがい、その外側操作部15を離すと、両支持アーム7が互いに閉じて支持状態になり、両支持アーム7に剃刀ヘッド1が支持される。しかし、外側操作部15を押したまま両支持アーム7に剃刀ヘッド1を当てがう必要があり、両支持アーム7に剃刀ヘッド1を支持しにくい。
* There was a risk that the razor head 1 could be detached from the two support arms 7 by inadvertently pressing the outer operation portion 15.
* When the outer operating unit 15 is pushed and the support arms 7 are opened from each other, the razor head 1 is applied to the two supporting arms 7, and when the outer operating unit 15 is released, the supporting arms 7 are closed and supported. Thus, the razor head 1 is supported by both the support arms 7. However, it is necessary to apply the razor head 1 to the both support arms 7 while pressing the outer operation portion 15, and it is difficult to support the razor head 1 to the both support arms 7.

* 前記左右両支持アーム7が一対の支軸部18により回動可能に支持されているので、この左右両支軸部18間を結ぶ左右方向で部品組付体3のサイズが大きくならざるを得ない。そのため、ホルダ2の頭部4b,5bのサイズも大きくなる。   * Since the left and right support arms 7 are rotatably supported by a pair of support shafts 18, the size of the component assembly 3 must be increased in the left-right direction connecting the left and right support shafts 18. I don't get it. Therefore, the size of the heads 4b and 5b of the holder 2 is also increased.

* 前記部品組付体3において一体的に設けられた左右両案内壁部23,24の案内面23a,24a間の案内通路25で前記左右両支持アーム7が開閉動する。この左右両支持アーム7の開閉動ストロークに合わせて左右両案内壁部23,24の延設長さも設定しなければならない。この左右両案内壁部23,24の延設長さを大きくすると、ホルダ2の頭部4b,5bのサイズも大きくなる。そのサイズが制限されているため、左右両支持アーム7は開動時に案内通路25から突出し、左右両支持アーム7の触れ防止効果を十分に発揮しない。   * The left and right support arms 7 are opened and closed in the guide passage 25 between the guide surfaces 23a and 24a of the left and right guide wall portions 23 and 24 provided integrally in the component assembly 3. The extension lengths of the left and right guide wall portions 23 and 24 must be set in accordance with the opening / closing movement strokes of the left and right support arms 7. When the extending length of the left and right guide wall portions 23, 24 is increased, the size of the heads 4b, 5b of the holder 2 is also increased. Since the size thereof is limited, the left and right support arms 7 protrude from the guide passage 25 when opened, and the effect of preventing the left and right support arms 7 from touching is not sufficiently exhibited.

この発明は、ホルダの頭部に部品組付体を組み付けた首振り式剃刀において、簡単な組付構造で機能を高めることを目的としている。   An object of the present invention is to improve the function of a swing-type razor in which a component assembly is assembled to the head of a holder with a simple assembly structure.
