本案は二重環縫ミシンに於て、下糸をルーパーに案内す
る鎌形案内部材の起伏装置に関する。[Detailed Description of the Invention] The present invention relates to a raising and lowering device for a sickle-shaped guide member that guides a bobbin thread to a looper in a double chainstitch sewing machine.
従来の二重環縫ミシンに於ける下糸をルーパーに導びく
鎌形案内部材は起立状態でルーパーに近接平行して設け
られ、且つルーパーの基部と一体に構成されているから
案内部材に設けている糸の通し孔に下糸を指先て差し通
す場合、糸の差し通しに不便が多く、これが縫製作業の
能率に影響するところが多い欠点がある。In a conventional double chainstitch sewing machine, the sickle-shaped guide member that guides the bobbin thread to the looper is installed close to and parallel to the looper in an upright state, and is integrated with the base of the looper. When inserting the bobbin thread into the thread threading hole using the tip of your finger, it is often inconvenient to thread the thread through, and this has the disadvantage that it often affects the efficiency of sewing work.
本案はこの欠点を除くことを目的として、鎌形案内部材
を改良し、糸を通す際、案内部材を糸の通し易い様に側
方に倒すことができるように構成したものである。In order to eliminate this drawback, the present invention improves the sickle-shaped guide member so that when threading the thread, the guide member can be tilted to the side to facilitate threading.
本案を図面に示した実施例によって説明すると、1はミ
シン本体にして、−側に上糸のボビン2が設けられ、機
台3の一側に下糸のボビン4が設けられている。The present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a sewing machine body, a bobbin 2 for an upper thread is provided on the minus side, and a bobbin 4 for a lower thread is provided on one side of the machine base 3.
5は昇降する針6の直下に設けたルーパーにして、軸支
7される基部8の外端部に基部と一体の溝型保持枠9が
ルーパーと平行して立設され、この溝型保持枠の着根に
近き外側に、軸受10を設け、この軸受に上方を鎌形に
屈曲形成した下糸11の案内部材12の基部を軸着15
し、該案内部材は溝型保持枠9内に第2図に示すように
嵌合起立させ、溝型保持枠9の縁部に取付けたばね板1
3に係脱可能に掛は止め保持させている。Reference numeral 5 designates a looper provided directly below the needle 6 that moves up and down, and a groove-shaped holding frame 9 integral with the base is erected parallel to the looper at the outer end of the base 8 supported by the shaft 7. A bearing 10 is provided on the outside near the root of the frame, and the base of the guide member 12 for the bobbin thread 11, whose upper part is bent into a sickle shape, is attached to the bearing 15.
The guide member is fitted and erected within the groove-shaped holding frame 9 as shown in FIG.
3, the hook is removably fixed and held.
14は案内部材12に設けた下糸11の差し通し案内孔
である。14 is a guide hole provided in the guide member 12 through which the bobbin thread 11 is inserted.
本案は以上のように構成されているから、下糸11を案
内部材12の案内孔14に第2図に示すように差し通す
場合は、案内部材12を溝型保持枠9内より外方に引き
出すように指先で引けば、ばね板13により掛は止めら
れた案内部材12は、ばね板から外れて第3図に示すよ
うに外方に倒れ、下糸の差し通し易い状態となり、依っ
て指先で容易に下糸を案内孔14に差し通すことができ
る。Since the present invention is constructed as described above, when inserting the bobbin thread 11 into the guide hole 14 of the guide member 12 as shown in FIG. If you pull it out with your fingertips, the guide member 12, which has been stopped by the spring plate 13, will come off the spring plate and fall outward as shown in FIG. 3, making it easy to insert the bobbin thread. The bobbin thread can be easily passed through the guide hole 14 with a fingertip.
斯くて糸を通した後は指先で案内部材12を起立させ、
溝型保持枠9内に圧入させると案内部材は第2図に示す
状態に戻り、ばね板13によって掛は止められて安定し
勝手に倒れることはない。After threading the thread, raise the guide member 12 with your fingertips,
When the guide member is press-fitted into the groove-shaped holding frame 9, the guide member returns to the state shown in FIG. 2, and the spring plate 13 prevents the guide member from falling over.
この鎌形案内部材は、従来の二重環縫ミシンにも設けら
れているが、基部がルーパーの基部と一体に構成され、
起伏させることができないので、案内部材は常に第2図
のような状態にあり、従って糸を通す場合、ルーパーが
障害となり、糸の挿通が極めて困難で、意外の手数がか
かる不便がある。This sickle-shaped guide member is also provided in conventional double chainstitch sewing machines, but the base is configured integrally with the base of the looper,
Since it cannot be raised or lowered, the guide member is always in the state shown in FIG. 2, and therefore, when threading the thread, the looper becomes an obstacle, making it extremely difficult and inconvenient to insert the thread.
これがため縫製作業時、この下糸のかけ通しに時間を要
して作業能率に犬きな影響を与える不利がある。Therefore, during sewing work, threading the bobbin thread through the sewing machine takes time, which has a disadvantage in that work efficiency is seriously affected.
然るに本案は上記したように、案内部材12を下糸の通
し易い第3図に示す状態に倒すことができるようにした
がため、下糸の差し通しが極めて容易となり、従来のよ
うな糸の差し通しに時間を要することがなく、従って縫
製作業の能率を向上させることができる効果がある。However, as described above, in the present invention, the guide member 12 can be tilted to the state shown in FIG. 3 where it is easy to pass the bobbin thread, so it is extremely easy to pass the bobbin thread through, and it is not necessary to insert the bobbin thread as in the conventional case. It does not take much time to insert the material, which has the effect of improving the efficiency of sewing work.
