果として縫製布の縫目量が変化する欠点があった。Conventionally, this type of device has a continuous ■-shaped groove on the back side of the dial, and a pin 20 with a conical tip biased by a spring is engaged with the groove as shown in FIG. , the rotating position of the dial was fixed, but in this case ■ If the pressing force of the pin that engages the shape groove is large, it becomes very difficult to rotate the dial, and if the pressing force is reduced, the sewing machine will not operate properly. There was a drawback that the position of the dial would shift due to collision between the cam surface of the guide lever and the adjustment screw, resulting in a change in the amount of stitches in the sewing cloth.

４は案内テコで゛、ミシンアーム１に軸５によって揺動
自在に軸支されており、その揺動角度の度合によって縫
目量の大小が決まる構造で、既に公知のとおりである。Reference numeral 4 denotes a guide lever, which is rotatably supported on the sewing machine arm 1 by a shaft 5, and has a structure in which the amount of stitches is determined by the degree of the swing angle, and is already known in the art.
７はミシンアーム１に進退自在に螺着された調節ねしで
、案内テコ４のカム部６に対応して設けられ、調節ねじ
７の進退位置によって案内テコ４の揺動角度が規制され
る。Reference numeral 7 denotes an adjustment screw screwed onto the sewing machine arm 1 so that it can move forward and backward, and is provided corresponding to the cam portion 6 of the guide lever 4, and the swing angle of the guide lever 4 is regulated by the forward and backward positions of the adjustment screw 7. .
８は縫目ダイヤルで、上記調節ねじ７に止めネジ９によ
って固着しており、その表面側には縫目量を示す数字８
ａを表示し、裏面には第４図に示すように係止用のＶ字
形溝１０を上記数字８ａの位置と関連づけて円周上等分
に配設されている。8 is a stitch dial, which is fixed to the adjustment screw 7 by a set screw 9, and the number 8 indicating the stitch amount is on the surface side.
As shown in FIG. 4, on the back side, V-shaped grooves 10 for locking are arranged at equal intervals on the circumference in association with the positions of the numerals 8a.
すなわちＶ字形の溝１０は縫目量に対応する間隔を有し
て設けられている。That is, the V-shaped grooves 10 are provided at intervals corresponding to the amount of stitches.
１１は係止ピンで、その支持部はミシンアーム１のピン
穴１２に遊嵌しており、先端部１１ ａは前記Ｖ字形の
溝１０と合致する尖頭形状をしており、がつ外周部に回
り止めをなす平面部１１ ｂを有している。Reference numeral 11 denotes a locking pin, the supporting portion of which is loosely fitted into the pin hole 12 of the sewing machine arm 1, and the tip portion 11a has a pointed shape that matches the V-shaped groove 10, and the outer circumference of the locking pin 11 is a locking pin. It has a flat portion 11b that prevents rotation.
またピン穴１２には押しばね１３が装着されていて、常
時係止ピン１１をばね張力によって縫目ダイヤル８の裏
面側を押圧している。Further, a push spring 13 is attached to the pin hole 12, and the locking pin 11 is constantly pressed against the back side of the stitch dial 8 by spring tension.
次に１４は回り止め板で、ミシンアーム１に縫目ダイヤ
ル８の間に設けられており、調節ねじ７の軸部７ａと遊
嵌する穴部１４ａと、係止ピン１１の平面部１１ ｂと
遊嵌する回り止め溝１４ｂを有している。Next, reference numeral 14 denotes a rotation stopper plate, which is provided on the sewing machine arm 1 between the stitch dial 8 and has a hole 14a that loosely fits the shaft 7a of the adjusting screw 7, and a flat surface 11b of the locking pin 11. It has a rotation prevention groove 14b that loosely fits therein.
１５は押しばねで、回り止め板１４を常にミシンアーム
１側に押圧している。Reference numeral 15 denotes a pressure spring that constantly presses the rotation prevention plate 14 toward the sewing machine arm 1 side.
次に上記構成における動作について説明する。Next, the operation in the above configuration will be explained.
まず、ミシン操作者が縫製条件に応じて縫目量を変化さ
せようとするときは、ダイヤル８を希望する角度だけ回
動するのみで、押しばね１３のばね張力によって押圧さ
れなからＶ字形の溝１０と係止ピン１１の先端部１１
ａとの保合位置が変化して縫目ダイヤル８の位置を固定
することになる。First, when the sewing machine operator wants to change the stitch amount according to the sewing conditions, all he has to do is turn the dial 8 by the desired angle. Groove 10 and tip 11 of locking pin 11
The position of the stitch dial 8 is fixed by changing the engagement position with the stitch dial 8.
そこでこの際この考案によれば、縫目ダイヤル８と係止
ピン１１の係合時においては、回動を阻止する面を広く
して直線状とし、がっ係止ピン１１の回り止め板１４を
設けたので、押しばね１３のばね力を比較的弱くしても
係止ピンによる縫目ダイヤル８の固定は確実で、しがも
軽い操作力で容易にダイヤルを回動することができ得る
効果を有するものである。Therefore, according to this invention, when the stitch dial 8 and the locking pin 11 are engaged, the surface that prevents rotation is made wide and linear, and the rotation prevention plate 14 of the locking pin 11 is made wide and linear. As a result, even if the spring force of the push spring 13 is relatively weak, the stitch dial 8 can be securely fixed by the locking pin, and the dial can still be easily rotated with a light operating force. It is effective.
