Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotation assistance screwdriver with a gear adapted to produce a large number of rotations of a screwdriver in a single operation without strain. <P>SOLUTION: A main shaft is attached to a portion below a handle A so as to turn round, and a chuck formed by combining U-shaped screw clips in a cross shape is attached to the shaft. A detachable screwdriver E is set to the chuck, and the screwdriver is rotatable per chuck. A small gear G1 is attached to a main shaft portion between the handle and the chuck, and a large gear G2 is attached laterally thereto. The large gear is attached laterally to the main shaft of the same handle with the teeth thereof engaged with the small gear. When the large gear is rotated, the small gear is rotated, namely, the chuck and the screwdriver are rotated. The number of rotations depends on the ratio of the number of teeth on the large gear and that on the small gear. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

工具分野、手動ネジ用ドライバ−。Tool field, manual screwdriver.

自案特許願い２００７−１９６７１９の回転アシスト付きドライバ−の内容に、ギヤ（歯車）機能を追加しました。A gear function has been added to the contents of the self-patent request 2007-196719 with rotation assist driver.

手動で使用するネジ用ドライバ−を手力だけで回すのは、非常に疲れます。
ドライバ−を回転させる時に使う筋肉は、ほとんど手の指の筋肉です。
使う筋肉が小さく限定されている上に、回転数も稼げませんので疲れが出やすいのです。
ドライバ−を楽にするためには、一度にたくさん回転できるようにする必要があります。It is very tiring to turn the screw driver used manually by hand.
The muscles used to rotate the driver are mostly finger muscles.
The muscles to be used are limited and small, and the number of rotations cannot be gained, making it easy to get tired.
To make the driver easier, you need to be able to rotate a lot at once.

手の下でドライバ−が抵抗なく回転できるよう、ハンドルより下の部分にくるくる回るように主軸を取り付け、
その軸にＵ字型のバネクリップを十字型に組み合わせたチャックを取り付け、
チャックには取り外し可能なドライバ−をセットし、チャック毎ドライバ−が回転可能なようにする。
更に上記ハンドルと上記チャックの間の主軸部に小さい方のギヤ（歯車）を取り付け、その並びに更に大きい方のギヤ（歯車）を取り付ける。大きい方のギヤ（歯車）は、同じハンドルの主軸の横にその小さな方のギヤ（歯車）に歯がかみ合った状態で取り付ける。
大きな方のギヤ（歯車）を回転させると小さなギヤ（歯車）が回転、即ちチャック及びドライバ−が回転する。
その回転数は大きなギヤ（歯車）と小さなギヤ（歯車）の歯の数との比率によって決定する。
［発明を実施する為の最良の形態］Attach the spindle so that the screwdriver can rotate without resistance under the hand.
Attach a chuck that combines a U-shaped spring clip in a cross shape to the shaft,
A removable driver is set on the chuck so that the chuck-by-chuck driver can rotate.
Further, a smaller gear (gear) is attached to the main shaft portion between the handle and the chuck, and a larger gear (gear) is attached. The larger gear (gear) is attached next to the main shaft of the same handle in a state in which teeth are engaged with the smaller gear (gear).
When the larger gear (gear) is rotated, the smaller gear (gear) is rotated, that is, the chuck and the driver are rotated.
The number of rotations is determined by the ratio between the number of teeth of the large gear (gear) and the small gear (gear).
[Best Mode for Carrying Out the Invention]

図１のＡはハンドルです。Ｃ１は主軸でＣ２はギヤ（歯車）用の軸です。
Ｇ１は小ギヤ（歯車）でＧ２は大ギヤ（歯車）です。
Ｇ２を回転させると、Ｇ１が回転します。
その回転数はＧ２の歯数とＧ１の歯数の比率によって決まります。
仮にＧ２の歯の数が４８でＧ１の歯の数が１２の場合、Ｇ２が１回転するとＧ１は４回転します。A in Fig. 1 is a handle. C1 is the main shaft and C2 is the gear (gear) shaft.
G1 is a small gear (gear) and G2 is a large gear (gear).
When G2 is rotated, G1 rotates.
The number of rotations is determined by the ratio of the number of G2 teeth to the number of G1 teeth.
If the number of G2 teeth is 48 and the number of G1 teeth is 12, G1 rotates 4 times when G2 rotates once.

図１のＢはハンドル固定金具です。ハンドルが軸から抜けないようにしてあります。しかし、ハンドル自体を固定していませんのでハンドルは抜けないで、尚且つハンドルより下は回転可能となっています。B in Fig. 1 is a handle fixing bracket. The handle is kept from coming off the shaft. However, since the handle itself is not fixed, the handle does not come out, and it can be rotated below the handle.

図１のＥはドライバ−本体で、Ｄはドライバ−をセットするクリップチャック部分です。Ｕ字型バネクリップを十字型に組んだ羽根車形の形状になっています。
その張り出した部分に手の指を引っ掛けて回転させる事も可能です。
クリップチャックの円が大きく、力も掛けやすいので楽に回転ができます。
左手で羽根車の部分を手の平内で回しても楽に、多く回転できます。In Fig. 1, E is the driver body, and D is the clip chuck part where the driver is set. It has an impeller shape with a U-shaped spring clip assembled in a cross shape.
It is also possible to rotate it by hooking your fingers on the overhanging part.
The circle of the clip chuck is large and easy to apply force, so it can be rotated easily.
Even if you turn the impeller part in the palm of your hand with your left hand, you can easily rotate a lot.

ドライバ−はハンドル軸Ｃ１をソケット穴Ｅ１に差し入れてセットします。これによりハンドル軸Ｃ１とドライバ−の縦方向の方向性が一致し、又、横方向からの力によって軸がぶれるのを防ぎます。The driver sets the handle shaft C1 by inserting it into the socket hole E1. As a result, the vertical direction of the handle shaft C1 and the driver match, and the shaft is prevented from being shaken by lateral force.

図１のＤ１Ｄ２はクリップチャックの根元部分です。図２、３に示しますようにドライバ−の四角の４面にピッタリとくっつく、段違いの、四角い形状になっています。この四角のがっちりとした部分で、ドライバ−の回転軸に加わる回転方向の力に耐えるようになっています。D1D2 in Fig. 1 is the base part of the clip chuck. As shown in Figs. 2 and 3, it has a square shape with different steps that fits exactly on the four sides of the driver's square. This solid part of the square is designed to withstand the rotational force applied to the driver's rotating shaft.

図１のＤ３Ｄ４はクリップチャックの先端部分です。図２に示しています先端部分には、バネクリップですので内側に向けて力がかかっていて、尚且つ、切れ込みでドライバ−が抜けないように保持しています。D3D4 in Fig. 1 is the tip of the clip chuck. The tip shown in Fig. 2 is a spring clip so that force is applied toward the inside, and it is held so that the driver does not come off due to the cut.

図１のＥのドライバ−は、図４、５に示しますようにはずすことが簡単にできます。必要に応じて、セットして使うこともはずして使うことも可能です。又、必要に応じてＥ２の先端部分が違う、例えばプラス型のチップの付いたドライバ−に変えたり、チップ自体を変えたりすれば、迅速な交換、あるいは多様な使い方ができます。The driver E in Fig. 1 can be easily removed as shown in Figs. It can be set and used as needed. If necessary, change the tip of E2 to a different one, such as a driver with a plus-type chip, or change the chip itself for quick replacement or various uses.

疲労の減少
従来型のドライバ−を使用する時、ドライバ−を回転させる方の指は回転とドライバ−の保持の両方を兼ねていたので指で摘む形で回すしかなく、指が疲れましたが、ギヤ（歯車）付回転アシストドライバ−使用の場合は手の平でドライバ−を押しながら保持出来るので、回転動作にのみ指全体、あるいは手全体の筋肉を使用でき、
又、大きなギヤ（歯車）の方Ｇ２を回転させると、Ｇ１が多回転する為、回転作業を少ない動作で出来、疲労が軽減します。
その回転数はＧ２の歯数とＧ１の歯数の比率によって決まります。
仮にＧ２の歯の数が４８でＧ１の歯の数が１２の場合、Ｇ２が１回転するとＧ１は４回転します。
効率の良い回転、作業時間の短縮可能
上記ギヤ（歯車）比を利用したドライバ−回転は効率が良く、作業時間の短縮可能になります。
力強い締めが可能
羽根車形クリップチャックの外周円が大きいので、チャックの張り出し部に指を掛けて回転させた場合、力強い締めも楽にできます。Fatigue reduction When using a conventional driver, the finger that rotates the driver serves as both rotation and holding of the driver. In the case of using a rotation assist driver with gears (gears), it can be held while pushing the driver with the palm of your hand, so you can use your entire finger or muscle of your entire hand only for rotational movement,
In addition, when G2 of the large gear (gear) is rotated, G1 rotates multiple times, so the rotation work can be done with less movement and fatigue is reduced.
The number of rotations is determined by the ratio of the number of G2 teeth to the number of G1 teeth.
If the number of G2 teeth is 48 and the number of G1 teeth is 12, G1 rotates 4 times when G2 rotates once.
Efficient rotation and reduction of work time Driver rotation using the above gear (gear) ratio is efficient and can reduce work time.
Powerful tightening is possible The outer circumference of the impeller-type clip chuck is large, so if you put your finger on the overhanging part of the chuck and rotate it, you can easily perform powerful tightening.
