図示実施例は上記の如く構成するものにして、以下、ミシン針装着具1によるミシン針Aの装着手順を説明する。   The illustrated embodiment is configured as described above, and the procedure for mounting the sewing needle A by the sewing needle mounting tool 1 will be described below.

先ず、図1に示すように、縫製ミシンBの押え金Bdを下限位置まで降下させ、ミシン針Aを上限位置まで上昇させた後、針止めネジBcを緩めて、針棒Ba下端の針装着部Bbからミシン針Aを予め抜き取っておく。   First, as shown in FIG. 1, the presser foot Bd of the sewing machine B is lowered to the lower limit position, the sewing needle A is raised to the upper limit position, and then the needle set screw Bc is loosened to attach the needle at the lower end of the needle bar Ba. The sewing needle A is previously extracted from the portion Bb.

次に、図2に示すように、ミシン針装着具1に設けた把持部4の操作部5を、把持部4を把持する手の指でコイルスプリング8に抗して後端側へ移動させ、当接部7を、針支持体6の溝部6aから抜き取るか、針支持孔3aに挿入されるミシン針Aの幹部Ac外面に対して当接回避される当接解除位置に移動するとともに、その当接解除状態を、交換用のミシン針Aが挿入されるまで維持する。   Next, as shown in FIG. 2, the operating portion 5 of the grip portion 4 provided on the sewing needle attachment 1 is moved to the rear end side against the coil spring 8 with the finger of the hand gripping the grip portion 4. The abutment portion 7 is extracted from the groove portion 6a of the needle support 6 or moved to a contact release position where contact with the outer surface of the trunk portion Ac of the sewing needle A inserted into the needle support hole 3a is avoided. The contact release state is maintained until the replacement sewing needle A is inserted.

次に、交換用のミシン針Aを、針先部Abから先行して、針支持部3の針支持孔3aに対して上方から下方に向けて垂直に挿入するとともに、ミシン針Aの幹部Ac外面に形成した糸溝Ae側を、当接部7と対向する方向に向けて挿入する。   Next, the replacement sewing needle A is inserted vertically from the upper side to the lower side with respect to the needle support hole 3a of the needle support portion 3 in advance from the needle tip portion Ab, and the trunk portion Ac of the sewing needle A. The thread groove Ae side formed on the outer surface is inserted in a direction facing the contact portion 7.

ミシン針Aのテーパ部Afを針支持孔3aのテーパ面3bに当接して、ミシン針Aの柄部Aa全長を針支持孔3a上方に突出し、針先部Abを針支持孔3a下方に突出した状態に支持する。   The taper portion Af of the sewing needle A is brought into contact with the taper surface 3b of the needle support hole 3a, the entire handle Aa of the sewing needle A protrudes above the needle support hole 3a, and the needle tip portion Ab protrudes below the needle support hole 3a. I support it in the state.

次に、図3、図4に示すように、操作部5から指を離して、当接解除方向へのスライド操作を解除するとともに、当接部7を、コイルスプリング8に蓄積された復元力により、針支持部3の針支持孔3aに挿入されたミシン針Aの幹部Ac外面に対して当接される方向に移動させ、ミシン針Aを所定の方向に向いた状態に回転規制する。   Next, as shown in FIGS. 3 and 4, the finger is released from the operation unit 5 to release the sliding operation in the contact release direction, and the contact portion 7 is restored to the restoring force accumulated in the coil spring 8. Accordingly, the sewing needle A is moved in a direction in contact with the outer surface of the trunk portion Ac of the sewing needle A inserted into the needle support hole 3a of the needle support portion 3, and the rotation of the sewing needle A in a predetermined direction is restricted.

すなわち、図5に示すように、ミシン針Aの糸溝Aeが図中の実線又は仮想線で示す方向に向いている場合、コイルスプリング8に蓄積された復元力により、当接解除位置に移動させた当接部7前端を、ミシン針Aの幹部Ac外面に形成した糸溝Aeの片側縁部に対して当接すると、その当接力によりミシン針Aが軸芯を中心として回転する。   That is, as shown in FIG. 5, when the thread groove Ae of the sewing needle A is oriented in the direction indicated by the solid line or the phantom line in the drawing, it moves to the contact release position by the restoring force accumulated in the coil spring 8. When the front end of the abutted portion 7 is brought into contact with one side edge portion of the thread groove Ae formed on the outer surface of the trunk portion Ac of the sewing needle A, the sewing needle A rotates about the axis by the contact force.

図6に示すように、当接部7の当接により、ミシン針Aが、糸溝Aeの両側縁部に対して当接部7前端が平行に当接される角度に回転すると、当接部7前端が糸溝Aeの両側縁部に対して平行に当接されるため、右方向及び左方向へのミシン針Aの回転が阻止され、糸溝Aeが当接部7と対向する方向に向いた状態に回転規制される。   As shown in FIG. 6, when the abutment of the abutment 7 causes the sewing needle A to rotate to an angle at which the front end of the abutment 7 abuts parallel to both side edges of the thread groove Ae, Since the front end of the portion 7 is in contact with both side edges of the thread groove Ae in parallel, rotation of the sewing needle A in the right and left directions is prevented, and the direction in which the thread groove Ae faces the contact portion 7 Rotation is restricted to the state suitable for.

次に、図1の実線に示すように、ミシン針装着具1を、作業者側から見て針支持部3が縫製ミシンBの被縫製物送り方向と一致する状態に手で把持して、縫製ミシンBの針棒Ba下方に移動させ、針支持部3の針支持孔3aに挿入されたミシン針3を、針棒Ba下端に設けた針装着部Bb直下に位置させる。   Next, as shown by the solid line in FIG. 1, the sewing machine needle mounting tool 1 is grasped by hand so that the needle support portion 3 coincides with the sewing material feed direction of the sewing machine B as viewed from the operator side. The sewing machine B is moved below the needle bar Ba of the sewing machine B, and the sewing machine needle 3 inserted into the needle support hole 3a of the needle support part 3 is positioned directly below the needle mounting part Bb provided at the lower end of the needle bar Ba.

上記ミシン針Aの幹部Acに形成した糸溝Aeの両側縁部に対する当接部7の当接方向と、把持部4上面に形成した装着方向表示部10の縦線10aとが一致しているので、その縦線10aの方向を目視確認すれば、ミシン針Aの幹部Acに形成した糸溝Aeの向きを正確に把握することができる。   The contact direction of the contact portion 7 with respect to both side edges of the thread groove Ae formed on the trunk portion Ac of the sewing needle A coincides with the vertical line 10a of the mounting direction display portion 10 formed on the upper surface of the grip portion 4. Therefore, if the direction of the vertical line 10a is visually confirmed, the direction of the thread groove Ae formed in the trunk portion Ac of the sewing needle A can be accurately grasped.

つまり、手で把持したミシン針装着具1を、把持部4上面に表示した装着方向表示部10の縦線10aと、縫製ミシンBの被縫製物送り方向とが一致する方向に向けるとともに、ミシン針装着具1を上方に持ち上げて、針支持部3の針支持孔3a上方に突出するミシン針Aの柄部Aaを、針棒Ba下端の針装着部Bbに対して下方から上方に向けて鉛直に差し込み、柄部Aaが当接する差し込み限界位置まで押し込んだ後、針止めネジBcで締付け固定すれば、ミシン針Aを、作業者側から見て糸溝Aeが手前側を向いた前向き状態に装着することができる。   That is, the sewing needle mounting tool 1 gripped by hand is directed in a direction in which the vertical line 10a of the mounting direction display unit 10 displayed on the upper surface of the gripping unit 4 and the sewing material feed direction of the sewing machine B coincide with each other. The needle mounting tool 1 is lifted upward, and the handle Aa of the sewing needle A that protrudes above the needle support hole 3a of the needle support portion 3 is directed upward from below with respect to the needle mounting portion Bb at the lower end of the needle bar Ba. If the sewing needle A is viewed from the operator side, the thread groove Ae faces forward when the machine is inserted vertically and pushed to the insertion limit position where the handle Aa contacts, and then tightened and fixed with the needle set screw Bc. Can be attached to.

また、図1の仮想線に示すように、ミシン針装着具1を、作業者側から見て針支持部3が縫製ミシンBの被縫製物送り方向と直交する右向き状態に手で把持して、装着方向表示部10の縦線10aと、縫製ミシンBの被縫製物送り方向とが直交する方向に向けるとともに、針支持部3の針支持孔3aに挿入されたミシン針Aの柄部Aaを針棒Ba下端の針装着部Bbに差し込めば、ミシン針Aを、作業者側から見て糸溝Aeが左側を向いた横向き状態に装着することができる。なお、ミシン針Aの取付け方向は、家庭用や工業用のミシン或いはミシンの機種に応じて変更することができる。   Further, as indicated by the phantom line in FIG. 1, the sewing machine needle mounting tool 1 is grasped by hand in a state where the needle support portion 3 is in the right direction perpendicular to the sewing material feed direction of the sewing machine B as viewed from the operator side. The pattern Aa of the sewing needle A inserted in the needle support hole 3a of the needle support portion 3 while the vertical line 10a of the mounting direction display portion 10 and the sewing material B feed direction of the sewing machine B are directed orthogonally. Is inserted into the needle mounting portion Bb at the lower end of the needle bar Ba, the sewing needle A can be mounted in a lateral state with the thread groove Ae facing the left side when viewed from the operator side. The attaching direction of the sewing needle A can be changed according to a household or industrial sewing machine or a sewing machine model.

ミシン針Aを固定した後、操作部5を後端側の当接解除位置へ移動させ、当接部7を、ミシン針Aの幹部Acに対して当接が回避される位置に移動するとともに、ミシン針装着具1を下方に降下させ、針棒Ba下端の針装着部Bbに固体したミシン針Aを針支持部3の針支持孔3aから抜き取れば、ミシン針Aの装着が完了する。   After fixing the sewing needle A, the operating portion 5 is moved to the abutting release position on the rear end side, and the abutting portion 7 is moved to a position where contact with the trunk portion Ac of the sewing needle A is avoided. When the sewing needle attaching tool 1 is lowered and the sewing needle A solid on the needle attaching portion Bb at the lower end of the needle bar Ba is extracted from the needle supporting hole 3a of the needle supporting portion 3, the attaching of the sewing needle A is completed. .

また、コイルスプリング8を用いなくても、操作部5を指で前端側へ移動させて、当接部7を、ミシン針Aの幹部Ac外面に形成した糸溝Aeの片側縁部に対して手動操作で当接すれば、所定の向きに回転規制することができる。また、上述の装着作業を逆の手順で行えば、縫製ミシンBに設けた針棒Ba下端の針装着部Bbからミシン針Aを取り外す作業にも用いることができる。   Even if the coil spring 8 is not used, the operating portion 5 is moved to the front end side with a finger, and the contact portion 7 is made to the one side edge portion of the thread groove Ae formed on the outer surface of the trunk portion Ac of the sewing needle A. If the contact is made by manual operation, the rotation can be restricted in a predetermined direction. Further, if the above mounting operation is performed in the reverse procedure, the sewing needle A can be removed from the needle mounting portion Bb at the lower end of the needle bar Ba provided on the sewing machine B.

以上のように、ミシン針Aを、幹部Ac外面に形成した糸溝Aeを当接部7と対向する方向に向けて針支持部3の針支持孔3aに挿入し、当接部7を、ミシン針Aの幹部Ac外面に形成した糸溝Aeの両側縁部に対して平行に当接するので、右方向及び左方向へのミシン針Aの回転が阻止され、糸溝Aeが当接部7と対向する方向に向いた状態に回転規制することができる。また、糸溝Aeの向きと、当接部7の当接方向とが一致しているので、ミシン針Aを中心として、ミシン針装着具1を所望する向きに水平回動するだけで、ミシン針Aを、作業者側から見て糸溝Aeが前向き、横向きとなる状態に装着することができ、縫製ミシンBに設けた針棒Ba下端の針装着部Bbに対して所定の向きに回転規制したまま装着する作業が簡単且つ容易に行えるとともに、ミシン針Aの柄部Aa形状に関係なく、様々な種類のミシン針Aを装着する作業に用いることができる。   As described above, the sewing needle A is inserted into the needle support hole 3a of the needle support portion 3 so that the thread groove Ae formed on the outer surface of the trunk Ac is opposed to the contact portion 7, and the contact portion 7 is Since the needle abuts parallel to both side edges of the thread groove Ae formed on the outer surface of the trunk Ac of the sewing needle A, rotation of the sewing needle A in the right and left directions is prevented, and the thread groove Ae becomes the contact portion 7. Rotation can be restricted in a state facing the direction opposite to. Further, since the direction of the thread groove Ae and the contact direction of the contact portion 7 coincide with each other, the sewing needle mounting tool 1 can be simply rotated horizontally around the sewing needle A in the desired direction. The needle A can be mounted in a state in which the thread groove Ae is facing forward and sideways when viewed from the operator side, and rotates in a predetermined direction with respect to the needle mounting portion Bb at the lower end of the needle bar Ba provided on the sewing machine B. The operation of mounting while being regulated can be performed easily and easily, and can be used for the operation of mounting various types of sewing needles A regardless of the shape of the handle portion Aa of the sewing needle A.

図7は、1枚の板材を任意形状に折り曲げて形成した第2実施例のミシン針装着具11を示し、装着具本体12を、例えば金属板、合成樹脂板等のミシン針Aを支持するのに必要な剛性を有する1枚の板材で構成し、装着具本体12の前端側針支持部13に形成した針支持孔13aAと、針支持部13の前端部を下方に向けて直角に折り曲げ、その折り曲げ側端部を上方に向けて側面視U字状に折り返すとともに、その折り返し側端部を上下逆L字状に折り曲げてなる端部に形成した針支持孔13aBとで、上方の針支持孔13aAから下方の針支持孔13aBに向けて垂直に挿入されたミシン針Aを支持する。   FIG. 7 shows a sewing needle mounting tool 11 of a second embodiment formed by bending a single plate material into an arbitrary shape, and the mounting tool body 12 supports a sewing needle A such as a metal plate or a synthetic resin plate. The needle support hole 13aA formed in the front end side needle support portion 13 of the mounting tool body 12 and the front end portion of the needle support portion 13 are bent at a right angle downward.
