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、部品組付体をホルダの頭部に確実に連結して首振り式剃刀としての機能を高めることを目的としている。 An object of the present invention is to provide a swing-type razor in which a component assembly is assembled to the head of the holder, and to enhance the function of the swing-type razor by reliably connecting the component assembly to the head of the holder. Yes.
