本発明は、ミシンの足踏み速度制御を行わない、手動式
の速度制御装置の改良に関するもので、始動（低速）、
中速、高速等の運転及び停止の切り換えと、送り方向を
切り換えるいわゆる返し縫を一つの操作体で行わせるこ
とにより、ミシンの速度制御と返し縫の操作を容易なら

、一度低速のステップが選択できるようにして、停止予
定位置への運針精度を向上させることを目的とするもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a manual speed control device that does not control the pedal speed of a sewing machine.
By using one operating body to switch between running and stopping medium speed, high speed, etc., and to switch the feed direction, so-called reverse stitching, it is possible to easily control the speed of the sewing machine and operate reverse stitching, as well as in the process up to stopping. , the purpose of this is to enable the selection of a low-speed step even from the high-speed side, thereby improving the accuracy of hand movement to the expected stop position.
ミシンの始動時には、一般にいわゆる返し縫いといわれ
る送りの逆転を一旦性ってから正送りを行う事によって
縫端部の補強を行うことが多い。When starting a sewing machine, the seam edges are often reinforced by once reversing the feed, generally known as reverse stitching, and then performing normal feed.
また同様に縫い終りの場合も端部まで縫ってから返し縫
でもどして縫い終り部分の補強を行うことが多い。Similarly, at the end of sewing, the end of the sewing is often reinforced by sewing to the end and then backstitching.
これらの場合に足踏式速度調節によれば、返し縫ボタン
（またはレバー）によってその動作を容易に行うことが
でき、この切りかえは問題とならない。In these cases, if the foot-operated speed adjustment is used, the operation can be easily performed using the reverse stitch button (or lever), and this switching does not pose a problem.
しかし、足踏操作によらない手動式制御のミシンにあっ
ては、速度制御と停止に関連した動作を統轄した操作機
構によらなければ手際のよい切りかえができない。However, in manually controlled sewing machines that do not rely on foot operation, efficient switching is not possible unless there is an operating mechanism that controls operations related to speed control and stopping.
例えば返し縫のボタン（またはレバー）が速度調節の操
作部分と別のところにあれば、この間の手指の移動に時
間を要し、かつ到達して操作するまでの目視動作に注意
を要する。For example, if the reverse stitch button (or lever) is located in a separate location from the speed adjustment operation part, it takes time to move the fingers during this time, and care must be taken in visual movements until reaching and operating it.
更には、速度調節から停止を経て返し縫を行う様な一つ
の操作体を考えると、この間の切りかえは段階的である
ために迅速な切りかえの障害となる。Furthermore, when considering a single operating body that performs reverse stitching through speed adjustment, stopping, and reverse stitching, the switching during this period is gradual, which becomes an obstacle to rapid switching.
このように従来提案されている手動制御装置は、上記の
如き欠点を有しており、いずれにしても極めて操作性が
悪くミシンの使用者をして満足せしめうるものがなかっ
た。As described above, the conventionally proposed manual control devices have the above-mentioned drawbacks, and in any case, they are extremely poor in operability and have not been able to satisfy sewing machine users.
本発明は、上記したような従来品の欠点を除（ためにな
されたもので、ミシンの速度制御及び停止は操作体の回
転によって行い、返し縫はこの操作体を軸方向に押す事
によって行うように構成したものである。The present invention has been made to eliminate the above-mentioned drawbacks of conventional products.The speed of the sewing machine is controlled and stopped by rotating an operating body, and reverse stitching is performed by pushing this operating body in the axial direction. It is configured as follows.
このことによって、任意の縫速度において、前進縫から
返し縫に、或いは返し縫から前進縫に直ちに移行させる
ことができる。This makes it possible to immediately shift from forward stitching to reverse stitching or from reverse stitching to forward stitching at any sewing speed.
従つて、始動時に操作体を回転させると同時に軸方向に
押圧することによって、まず返し縫が行われ、続いて軸
方向の押圧を止めれば、前進縫が行われる。Therefore, by rotating the operating body and simultaneously pressing it in the axial direction at the time of starting, reverse stitching is first performed, and then, when the pressing in the axial direction is stopped, forward sewing is performed.
次に縫速度を上昇させて縫い、高速側から直ちに停止に
移ると停止予想位置への運針精度の保持が困難となる。Next, if the sewing speed is increased to sew, and the sewing machine immediately stops from the high speed side, it will be difficult to maintain the accuracy of needle movement to the expected stop position.
この場合通常の足踏式制御装置においては、停止位置に
近くなったところで足踏の調節を加減して減速し、それ
から踏板の踏込を解放することにより正確に予定位置に
停止させることができる。In this case, in a normal foot-operated control device, when the vehicle approaches the stop position, the foot pedal is adjusted to decelerate the vehicle, and then the footplate is released, thereby allowing the vehicle to stop accurately at the predetermined position.
本発明ではこの足踏の動作に近い操作性を得るため、高
速側からは中速を省略して直ちに低速のステップが選べ
るようにし、引き続いて停止のステップに移行させて低
速縫の状態からミシンを停止させることができるように
している。In the present invention, in order to obtain operability similar to this foot stepping operation, the medium speed step is omitted from the high speed side so that the low speed step can be selected immediately, and then the sewing machine is moved to the stop step to change the sewing machine from the low speed sewing state. It is possible to stop the
更に止むを得ず直ちにミシンを停止させたいときは、操
作体を強く操作して中速、低速をとばして直接停止のス
テップを選ぶことができるようにしている。Furthermore, when it is unavoidable to immediately stop the sewing machine, the user can strongly operate the operating body to skip the medium and low speeds and directly select the stop step.

まずミシンの停止状態では操作体２を最上部に置□き、

って操作軸４を介してスイッチ板１６は、可動片１７が
接点ＯＦＦに接続する位置に設定されている。First, when the sewing machine is stopped, place the operating body 2 at the top,
As shown in FIG. 6, the protrusion 14b of the split spring 14 has a recess S.
T, the cam plate 10 is pulled clockwise by the spring 11, and the parallel surface 10a is in contact with the pin 12c. Therefore, the switch plate 16 is activated via the operating shaft 4, and the movable piece 17 turns the contact OFF. It is set in the position to connect.
この場合サイリスタ３７にゲート信号が与えられないの
でミシンモータＳＭは停止している。In this case, since no gate signal is applied to thyristor 37, sewing machine motor SM is stopped.
低速縫を行うには、操作体２を約１５°時計方向に回転
させて分割ばね１４の凸部１４ｂを分割板１２の凹部し
に係合させる。To perform low-speed sewing, the operating body 2 is rotated approximately 15 degrees clockwise to engage the protrusion 14b of the split spring 14 with the recess of the split plate 12.
これにより可動片１７が接点ｌに接続され、サイリスタ
３７にはその導通角を小さくするゲート信号が与えられ
、ミシンモータＳＭは低速駆動される。As a result, the movable piece 17 is connected to the contact l, a gate signal is given to the thyristor 37 to reduce its conduction angle, and the sewing machine motor SM is driven at a low speed.
中速縫を行うには、操作体２を更に回転させ、分割ばね
１４の凸部１４ｂを凹部Ｍに係合させる。To perform medium speed sewing, the operating body 2 is further rotated to engage the convex portion 14b of the split spring 14 with the concave portion M.
これにより可動片１７が中速用接点ｍに接続され、サイ
リスタ３７には導通角を中位とするゲート信号が与えら
れ、ミシンモータＳＭは中速駆動される。As a result, the movable piece 17 is connected to the medium speed contact m, a gate signal with a medium conduction angle is given to the thyristor 37, and the sewing machine motor SM is driven at medium speed.
高速縫を行うには、操作体２を更に最下端まで回転させ
、第７図に示すように分割ばね１４の凸部１４ｂを分割
板１２の凹部Ｈに係合させる。To perform high-speed sewing, the operating body 2 is further rotated to the lowest end, and the protrusion 14b of the split spring 14 is engaged with the recess H of the split plate 12, as shown in FIG.
これにより可動片１７は高速用接点りに接続され、サイ
リスタ３７には導通角を最大とするゲート信号が与えら
れ、ミシンモータＳＭは高速駆動される。As a result, the movable piece 17 is connected to the high speed contact, a gate signal that maximizes the conduction angle is given to the thyristor 37, and the sewing machine motor SM is driven at high speed.
高速縫の状態からミシンを停止させるには操作体２を反
時計方向に回転させる。To stop the sewing machine from high-speed sewing, the operating body 2 is rotated counterclockwise.
これによって、まず操作軸４が回転し、第８図に示すよ
うに同時にカム板１０が分割板１２に対して先行回転し
、その凸部１０ｂが分割板１２の中速用の凹部Ｍをふさ
いでしまう。As a result, the operating shaft 4 first rotates, and at the same time, the cam plate 10 rotates in advance of the dividing plate 12 as shown in FIG. It's gone.
従って分割ばね１４の凸部１４ｂは凹部Ｍに係合するこ
となく、これを飛び越えて次の低速用の凹部しに係合す
ることとなる。Therefore, the convex portion 14b of the split spring 14 does not engage with the concave portion M, but instead jumps over this and engages with the next concave portion for low speed.
そこで任意に低速縫を行ない、次に操作体２を水平位置
までもどせば、第６図の状態となり、可動片１７は接点
ＯＦＦに接続され、ミシンモータＳＭは停止する。Then, by arbitrarily performing low-speed sewing and then returning the operating body 2 to the horizontal position, the state shown in FIG. 6 is achieved, the movable piece 17 is connected to the contact OFF, and the sewing machine motor SM is stopped.
次に縫作業を返し縫により開始し、続いて前進縫を行い
、縫の終りを再び返し縫で行う場合につき説明する。Next, a case will be described in which the sewing operation is started by reverse stitching, followed by forward sewing, and then the sewing is finished by reverse stitching again.
この場合には、まず操作体２を第４図仮想線の如（押圧

されリンク２７が右方に動き、スリーブ２６を右方に摺
動させ、駆動部材２８がスリーブ２６の突起２６ｃに係
合し、送り機構は逆送りの態勢となる。In this case, first, when the operating body 2 is pressed as shown by the imaginary line in FIG. The drive member 28 engages the protrusion 26c of the sleeve 26, and the feed mechanism is in the reverse feed position.
そこで前記と同様に操作体２を時計方向に約１５°回転
させれば、ミシンは低速縫で返し縫を行う。Therefore, if the operating body 2 is rotated approximately 15 degrees clockwise in the same manner as described above, the sewing machine performs reverse stitching at a low speed.
必要針数だけ返し縫を行ったら次に操作体２の押圧を解
除すれば、ミシンは低速回転しつつ直ちに前進縫へ移行
する。After performing reverse stitches for the required number of stitches, the user releases the pressure on the operating body 2, and the sewing machine immediately shifts to forward stitches while rotating at a low speed.
これはスイッチＳＷが開いて、電磁ソレノイドＳが消勢
され、スリーブ２６が左方にもどって、駆動部材２８が
突起２６ｂに係合するためである。This is because the switch SW is opened, the electromagnetic solenoid S is deenergized, the sleeve 26 returns to the left, and the drive member 28 engages with the protrusion 26b.
そこで必要なだけ前進縫を行う。Then, sew forward as many times as necessary.
最後に返し縫を行って、ミシンを停止させるには、再び
操作体２を第４図の如く押圧し、前記と同様に電磁ソレ

どせばミシンは停止する。Finally, to perform reverse stitching and stop the sewing machine, press the operating body 2 again as shown in Fig. 4, and set the feed mechanism to the reverse feed state by the action of the electromagnetic solenoid S as before. After sewing is completed, if the operating body 2 is returned to the horizontal position while being pressed, the sewing machine will stop.
即ち、単一の操作体２の抑圧及び回転操作により、返し
縫→前進縫−返し縫→ミシン停止の作業を片手で容易に
行うことができる。That is, by pressing and rotating the single operation body 2, the operations of reverse stitching, forward sewing, reverse stitching, and stopping the sewing machine can be easily performed with one hand.
なお操作棒８からソレノイドＳを介してリンク２７に至

常の送り調節器を用いて行ってもよいことは明らかであ
る。Note that it is clear that the portion from the operating rod 8 to the link 27 via the solenoid S may be mechanical, and that the forward/reverse feed conversion may be performed using an ordinary feed adjuster.
次に本発明の効果につき説明する。Next, the effects of the present invention will be explained.

ら、途中高速縫を行っていても、低速縫によりミシンを
正確に予定位置にて停止させることができるから、常時
低速縫を行う必要もなく、必要に応じ安心して高速縫を
行うことができる効果がある。First, with the device of the present invention, from a high-speed sewing state, it is possible to skip the medium-speed sewing step and immediately perform low-speed sewing, so even if high-speed sewing is being performed in the middle, the sewing machine can be accurately positioned at the planned position by low-speed sewing. Since the sewing machine can be stopped at any time, there is no need to constantly perform low-speed sewing, and high-speed sewing can be performed with peace of mind when necessary.
しかも足操作が不要であるから、特にポータプルミシン
において、極めて使いよく、また高能率の作業を行うこ
とができる。Moreover, since no foot operation is required, it is extremely easy to use and can perform highly efficient work, especially in porta-pull sewing machines.

である。Furthermore, by making the operating body 2 movable in the rotational direction and the axial direction, the rotational speed of the sewing machine can be controlled and the feed can be changed at the same time by its pressure. It can perform a difficult series of sewing tasks, ending with backstitching, resulting in a revolutionary effect.
