【考案の詳細な説明】
本案はミシンを使用中運転を急に止めた時等にボビンか
゛オーバーランしてボビンに巻かれた糸が余分に巻解し
てたるみ落ちその糸がボビンの支軸に絡みつくのを防止
するためのボビンのオーバーラン防止装置に係る。[Detailed explanation of the invention] This invention is based on the idea that when the sewing machine is suddenly stopped while in use, the bobbin overruns and the thread wound around the bobbin unwinds and falls slack, and the thread becomes the spindle of the bobbin. This relates to a bobbin overrun prevention device to prevent the bobbin from becoming entangled with the bobbin.
従来この種の絡み止め装置は色々の構造のものが知られ
ているが何れも複雑な構造となっている。Conventionally, this type of tangle-locking device has been known to have various structures, but all of them have complicated structures.
本案は極めて簡単な構造で而も確実にボビンのオーバー
ランを防止できる防止装置を提供しようとするものであ
る。The present invention is intended to provide a prevention device that has an extremely simple structure and can reliably prevent bobbin overrun.

たもので゛ある。The present invention will be explained with reference to an embodiment shown in the drawings. A wire having a required length and an appropriate thickness is bent into an inverted V shape, one of which is used as a pivot leg 1, and the other is used as a swinging rod 2. A guide tool is formed with a guide ring 4 for the thread 3 at the tip of the rod, and the shaft leg 1 of the guide tool is connected to a bobbin 6 and a support shaft 7 that fit into a support shaft 7 erected on the sewing machine arm. It is inserted into a gap 8 of a required width provided between the two, and is supported in contact with the upper hole edge of the bobbin.
尚図面中５はミシン本体、６はボビンである。In the drawings, numeral 5 represents the sewing machine body, and numeral 6 represents a bobbin.
本案のボビンのオーバーラン防止装置は、上記のように
構成されているからこれを使用する場合は第２図に示す
ように揺動杆２の案内環４に糸３をかけ通せばよいので
ある。The bobbin overrun prevention device of the present invention is constructed as described above, so when using this device, all that is required is to thread the thread 3 through the guide ring 4 of the swinging rod 2 as shown in Fig. 2. .
このようにしてボビンより引き出した糸を案内環４にか
け通しておけば引き出される糸３の張力は軸脚１に作用
しボビンに接した個所でボビンに制動を加えるためミシ
ンの運転が急停止してもボビンが慣性によってオーバー
ランすることはない。If the thread pulled out from the bobbin is passed through the guide ring 4 in this way, the tension of the thread 3 that is pulled out will act on the shaft leg 1 and apply braking to the bobbin at the point where it touches the bobbin, so the operation of the sewing machine will stop suddenly. However, the bobbin will not overrun due to inertia.
依って余分の糸が過剰に解けることがないから従来のミ
シンに見るような糸の解は過ぎでボビンの支軸に絡みつ
くという欠点はない、然して本案は上記のように単に針
金を逆Ｖ字形に屈曲した簡単なものであるから生産は容
易で安価にでき、而もボビンに装置するにしても単に軸
脚を上記したように支軸に嵌合したボビンと支軸との間
隙８内に差し込むだけの簡単な操作でよく、又ボビンを
差し換える際はボビンを支軸上から取り外すに先立ち軸
脚１を取り外せばよく、別設面倒な手数も要せず着脱は
至極簡単である。Therefore, the excess thread does not unravel excessively, so there is no problem with conventional sewing machines where the thread unravels too much and gets entangled with the spindle of the bobbin.In this case, however, the thread is simply twisted into an inverted V shape as described above. Since it is a simple piece bent in the shape of a shaft, production is easy and inexpensive, and even when it is installed on a bobbin, the shaft leg is simply inserted into the gap 8 between the bobbin and the shaft fitted to the shaft as described above. The operation is as simple as inserting the bobbin, and when replacing the bobbin, the spindle leg 1 need only be removed before removing the bobbin from the spindle, so attachment and detachment are extremely easy without requiring any troublesome separate installation.
以上のように、本案は従来のボビンのオーバーラン防止
装置にみるような複雑な構造と違い頗る簡単なもので、
而も取り扱いも簡易であり、各種ミシンにも自由に使用
できるので゛ミシンに於ける糸巻のオーバーラン防止装
置として極めて便利且重宝なものである。As mentioned above, the present invention is significantly simpler than the complicated structure seen in conventional bobbin overrun prevention devices.
Moreover, it is easy to handle and can be freely used in various sewing machines, making it extremely convenient and useful as a device for preventing overrun of thread windings in sewing machines.
