本発明は、前記提案のドライバー用ネジ保持具において、ドライバーによる部材へのネジ締め込みの最終段階において、ネジと部材との間に筒状体ネジ保持具の端部が挟まるという問題を解消するためになされたものであり、その目的は、ネジと部材との間に筒状体ネジ保持具の端部が挟まることがなく、電動ドライバーを使用した場合には、最後まで一気に締め付けることを可能とするドライバー用ネジ保持具を提供することにある。 The present invention eliminates the problem that the end of the cylindrical screw holder is sandwiched between the screw and the member in the final stage of tightening the screw into the member by the driver in the proposed screw holder for a driver. The purpose of this is to prevent the end of the cylindrical screw holder from being caught between the screw and the member, and when using an electric screwdriver, it can be tightened all at once It is providing the screw holder for drivers.

上記の目的を達成するための請求項１によるドライバー用ネジ保持具は、ドライバーの先端部に嵌着可能な軟質の筒状体からなり、該筒状体の内部にドライバーを用いて締め付けるネジを挿入、保持させて、締め付け作業時にネジがドライバーから外れないようにするために用いるネジ保持具において、前記筒状体のネジが挿入される部位が朝顔形に拡開可能となるよう該部位に縦方向のスリットを形成して、やや拡開された部位にネジが保持されるようにするとともに、前記部位の先端部に保持片を設けて、該保持片によりネジを安定して保持することができるようにし、ネジ締め時に前記筒状体のネジが挿入される部位が朝顔形に拡開してネジから離れるようにしたことを特徴とする。 In order to achieve the above object, a screw holder for a driver according to claim 1 is composed of a soft cylindrical body that can be fitted to a tip portion of a driver, and a screw that is tightened with a screwdriver inside the cylindrical body. In the screw holder used to insert and hold the screw so that the screw is not removed from the driver during the tightening operation, the portion into which the screw of the cylindrical body is inserted can be expanded into a morning glory shape. A vertical slit is formed so that the screw is held in a slightly expanded portion, and a holding piece is provided at the tip of the portion, and the screw is stably held by the holding piece. The part into which the screw of the cylindrical body is inserted at the time of screw tightening is expanded in a morning glory shape so as to be separated from the screw .

請求項２によるドライバー用ネジ保持具は、請求項１において、前記筒状体のネジが挿入される部位に、少なくとも３個所にスリットを形成したことを特徴とする。 The screw holder for a driver according to claim 2 is characterized in that, in claim 1, slits are formed in at least three places in a portion where the screw of the cylindrical body is inserted.

請求項３によるドライバー用ネジ保持具は、請求項１または２において、前記ドライバーが自動ネジ締めを行う電動ドライバーであることを特徴とする。 A screw holder for a driver according to a third aspect is the electric screw driver according to the first or second aspect, wherein the driver performs automatic screw tightening.

本発明によれば、ドライバーによる部材へのネジ締め込みの最終段階において、ネジと部材との間に筒状体ネジ保持具の端部が挟まることがなく、電動ドライバーを使用した場合には、最後まで一気に締め付けることを可能とするドライバー用ネジ保持具が提供される。 According to the present invention, in the final stage of screw tightening to the member by the driver, the end of the cylindrical screw holder is not sandwiched between the screw and the member, and when the electric screwdriver is used, Provided is a screw holder for a screwdriver that can be tightened all at once.

本発明のドライバー用ネジ保持具は、シリコンゴムなどの軟質のゴム、軟質のプラスチックから筒状体に形成されており、手動ドライバー、電動ドライバーのいずれにも適用することができる。図１に示すように、ドライバー用ネジ保持具１には、ネジ６が挿入される部位２が朝顔形に拡開可能となるよう部位２に縦方向のスリット４が形成される。部位２には少なくとも３個所にスリット４を形成するのが望ましく、スリット４を略等間隔に形成するのが部位２を朝顔形に拡開する上でさらに好ましい。 The screw holder for a driver of the present invention is formed into a cylindrical body from soft rubber such as silicon rubber and soft plastic, and can be applied to both manual drivers and electric drivers. As shown in FIG. 1, the screw holder 1 for drivers is formed with a longitudinal slit 4 in the part 2 so that the part 2 into which the screw 6 is inserted can be expanded in a morning glory shape. It is desirable to form slits 4 in at least three locations in the region 2, and it is more preferable to form the slits 4 at substantially equal intervals in order to expand the region 2 in a morning glory shape.

使用に際し、ドライバー用ネジ保持具１は、図２、図３に示すように、ドライバービット５の先端に嵌着され、ネジ締めに際して、図４に示すように、ネジ６をドライバー用ネジ保持具１の部位２に挿入する。この時、図４に示すように、スリット４により分割されて多又形状となっている部位２はやや拡開され、ネジ６は、拡開された部位２が図３のように閉じようとする力と軟質材からなる保持具１の材質特性の相互作用により部位２に保持される。この場合、ネジ保持具１の部位２の先端部に内側に折り曲げられた保持片３を設けておくことにより、ネジ６を安定して保持することができる。 In use, the screw holder 1 for a driver is fitted to the tip of a driver bit 5 as shown in FIGS. 2 and 3, and the screw 6 is screwed into the screw holder 6 as shown in FIG. Insert into site 1 of 1. At this time, as shown in FIG. 4, the portion 2 which is divided by the slit 4 and has a multi-pronged shape is slightly expanded, and the screw 6 is to close the expanded portion 2 as shown in FIG. It is held in the region 2 by the interaction between the force to perform and the material property of the holder 1 made of a soft material. In this case, the screw 6 can be stably held by providing the holding piece 3 bent inward at the tip of the portion 2 of the screw holder 1.

ついで、電動ドライバーを例として説明すると、図５に示すように、ドライバーを矢印のように回転させると、多又形状の部位２は遠心力により朝顔形に拡開してネジ６から離れ、ドライバーとネジとの関係はネジ保持具が無い場合と同じ状態となるが、ネジ６のネジ込み部８は部材９に到達して締め付けを開始しており、ドライバーが部材９に対してネジ６を押圧している状態となっているため、ネジ６が外れたり、落下したりすることはない。 Next, an electric driver will be described as an example. As shown in FIG. 5, when the driver is rotated as shown by an arrow, the multi-forked portion 2 expands into a morning glory shape due to centrifugal force and separates from the screw 6. The relationship between the screw and the screw is the same as when the screw holder is not provided, but the screwed portion 8 of the screw 6 reaches the member 9 and starts tightening. Since it is in the pressed state, the screw 6 does not come off or fall.

ネジ６を保持していた部位２がネジ６から離れるため、図６に示すように、最後まで一気に締め付けても、ネジ保持具１の先端がネジ６のネジ頭７と部材９との間に挟まることはない。ドライバーの回転が止まり締め付けが終了すると、多又形状の部位２は閉じ、ドライバーを部材９から引き抜いて締め付け作業は終了する。 Since the portion 2 holding the screw 6 is separated from the screw 6, as shown in FIG. 6, the tip of the screw holder 1 remains between the screw head 7 and the member 9 of the screw 6 even if tightened all at once. It won't get caught. When the driver stops rotating and tightening is finished, the multi-forked portion 2 is closed and the driver is pulled out of the member 9 to complete the tightening operation.

ネジ保持具１、特に多又形状の部位２については、保持力を維持しながら比較的低い回転数でも遠心力で拡開し易くなるようにするために、材質、スリット４の本数、スリット４の形成形態を改変することができ、ドライバービット５に対するネジ保持具１の嵌着度合を高めるために、筒状体からなるネジ保持具１の形態を変更することができる。また、ネジ保持具１にネジ６をより保持し易くするために、部位２の内面に凹凸や突条を設けることもできる。 For the screw holder 1, particularly the multi-pronged portion 2, the material, the number of slits 4, and the slit 4 are used so that the holding force is maintained and the centrifugal force can be easily expanded even at a relatively low rotational speed. The form of the screw holder 1 made of a cylindrical body can be changed to increase the degree of fitting of the screw holder 1 to the driver bit 5. Further, in order to make it easier to hold the screw 6 to the screw holder 1, irregularities and protrusions can be provided on the inner surface of the portion 2.

本発明によるドライバー用ネジ保持具の特徴は、締め付けの全工程においてネジを強固に保持するのではなく、保持を必要とする間だけ保持し、保持の必要が無くなった時点で保持具はネジから離れ、保持具がネジと部材の間に挟まるなどのトラブルを生じることなく、最後まで一気に締め付けを行うことができる点にある。 The feature of the screw holder for screwdrivers according to the present invention is that the screw is not held firmly in the entire tightening process, but is held only while it is required to be held. It is in the point that it can be tightened all at once without causing trouble such as separation and the holding tool being pinched between the screw and the member.

本発明によるドライバー用ネジ保持具は、軟質な材質で構成され、ネジを保持する部位がスリット４により分割されて多又形状となっているため、皿ネジ、なべネジ、六角ネジなどの異なるネジ形状のもの、異なるネジサイズ（Ｍ３ｍｍ〜Ｍ６ｍｍ程度）にも対応することができる。また、本発明のネジ保持具においては、ネジを緩めたり、取り外したりする作業も、ネジ保持具を付けたままで行うことが可能である。 The screw holder for a driver according to the present invention is made of a soft material, and a portion for holding the screw is divided by the slit 4 to have a multi-pronged shape. Shapes and different screw sizes (M3 mm to M6 mm or so) can be accommodated. In the screw holder of the present invention, the work of loosening or removing the screw can be performed with the screw holder attached.
