うようにしたタイプのものもある。Prior Art As is generally well known, a thread take-up moves up and down in conjunction with the upper shaft within a slit formed in the frame with the needle thread passed through the eye hole, supplying and absorbing thread necessary for forming seams. In many cases, when threading the thread through the eye hole, the threading operation is carried out by grasping the free end of the thread and passing it directly through the eye hole. As shown in No. 37-19122, Utility Model No. 49-9493, Japanese Patent Application Laid-open No. 60-139282, etc., the thread between both guides is captured in either the reciprocating stroke and threading into the eye hole is automatically carried out. There are also types that are made to do so.

There is also a balance device that is pulled in the same direction and opened during the return movement, eliminating the need for an eye hole.
考案が解決しようとする問題点
上述するような目孔を不要とした天秤装置はも
とより目孔への糸通しが自動的に行われるタイプ

り下げたりして方向転換をしなければならない。Problems that the invention aims to solve Not only the above-mentioned thread take-up device that does not require an eye hole, but also the type that automatically threads the thread through the eye hole eliminates the need to thread the thread through the thread take-up. Although the device has the advantage of being completely built into the sewing machine, all conventional devices require the thread to be raised or lowered to change direction when passing the thread from the tension device to the thread take-up.
本考案は、テンシヨン装置より天秤へ糸通しが
ワンタツチ操作に簡易に行えるようにしたもので
ある。 The present invention allows threading from the tension device to the thread take-up to be easily performed with a one-touch operation.
問題点を解決するための手段
本考案の天秤装置はそのため、上下に一定の間
隔を存し、糸が通される一対のガイドと、上軸に
連動してガイド間を水平方向に往復動する天秤を
有し、天秤が往復いづれか一方の行程にあるとき

位置するようにしたものである。Means for Solving the Problems Therefore, the balance device of the present invention has a pair of guides that are vertically spaced at a certain distance and through which the thread is passed, and a horizontal reciprocating motion between the guides in conjunction with the upper shaft. In the thread take-up device of a sewing machine that has a thread take-up and captures the thread between both guides when the thread take-up is in one of the reciprocating strokes, at least the above-mentioned trajectory after the thread capture is drawn by the thread hooking part of the thread take-up. Provide a thread guide to enclose the
Moreover, a tension device is incorporated in this thread guide, so that the tension plate and both guides are located on the same vertical plane.
ここでいう天秤装置には、目孔を有し、該目孔
への糸通しが天秤の動きによつて自動的に行なわ

前者のタイプのものにおいては目孔を、後者のタ
イプのものにおいては糸引掛け部をいう。 The thread take-up device referred to here includes one that has an eye hole and threading the thread through the eye hole is automatically performed by the movement of the thread take-up, and one that hooks the thread between both guides during forward movement. There is a type that both pulls and releases when moving backwards, so the thread hooking part is the eye hole in the former type, and the thread hooking part in the latter type.
糸案内は好ましくは断面コ形にされ、天秤の挿
入側を除き上記軌跡が三方から囲まれるように構
成されるが、天秤が水平方向に往復動する場合に
はことに天秤の挿入側とその反対側が開口するよ
うに、すなわち上記軌跡の上下二方を囲むように
構成してもよい。糸案内はまた少くとも糸捕捉後
の上記軌跡全体を囲うように構成されるのが望ま
しく、とくに上記軌跡の全長に亘つて天秤の大半
を囲み、弛んだ糸が糸案内からはみ出ないように
するのがより望ましい。 The thread guide is preferably U-shaped in cross section, and is configured so that the above trajectory is surrounded from three sides except for the insertion side of the thread take-up. However, when the thread take-up reciprocates in the horizontal direction, the thread guide is surrounded by the insertion side of the thread take-up and its surroundings. It may be configured so that the opposite side is open, that is, so as to surround both the upper and lower sides of the trajectory. It is also preferable that the thread guide is constructed so as to surround at least the entire trajectory after the thread is captured, and in particular to surround most of the thread take-up over the entire length of the thread so that the loose thread does not protrude from the thread guide. is more desirable.
更にまた糸案内にはテンシヨン装置のほか糸取
りバネを組付け、全体をユニツト化するのが望ま
しい。 Furthermore, it is desirable to assemble a thread take-up spring in addition to a tension device to the thread guide, thereby making the entire thread into a unit.
なお糸案内には上記軌跡を挟む両側壁に糸を通
すガイドとなる切込溝が形成される。 Note that the thread guide is formed with cut grooves on both side walls sandwiching the above-mentioned locus, which serve as guides for threading the thread.

つている。Embodiment As shown in Figure 3, a slit 2 is vertically formed in the top plate and front surface of the frame 1, and a thin box-shaped thread guide 3 with a pot-shaped cross section and an open rear end surface is formed in the front inner wall of the frame. protrudes laterally and is fixed,
A cut groove 4 is formed at a location corresponding to the slit 2. The base end of the balance 5 is pivotally attached to the frame, and is swung in the horizontal direction via a link 7 by a disk-shaped crank 6 that rotates in conjunction with the upper shaft, and the hook-shaped portion 5a at the tip is inserted into the thread guide 3. It is designed to move back and forth between the dotted line position and the dashed-dotted line position in Figure 1.
During forward movement, the thread extending in the vertical direction inserted into the cut groove 4 through the slit 2 is connected to the hook-shaped part 5a.
The thread is caught and pulled in a V-shape to the position shown by the dashed-dotted line, absorbing the slack in the thread and pulling out the thread from the bobbin winder.On the other hand, during the return motion, the thread is released, and the released thread is placed inside the thread guide. As the needle thread loop passes through the hook, it is gradually pulled out to provide the amount of thread necessary to pass through the hook.

果を有する。Effects of the invention As described above, the balance device of the present invention has a pair of guides that are vertically spaced at a constant interval and through which the thread is passed, and a balance that reciprocates horizontally between the guides in conjunction with the upper shaft. In a thread take-up device of a sewing machine that captures the thread between both guides when the thread take-up is in one of the reciprocating strokes, the thread guide that encloses at least the above-mentioned trajectory after the thread capture is drawn by the thread hook of the thread take-up. Moreover, a tension device is built into this thread guide so that the tension plate and both guides are located on the same vertical plane. The thread can be easily re-threaded from the tension device to both guides with one-touch operation.The tension device is built into a unit, making it easy to assemble.After release, the thread can be moved inside the thread guide. It has the effect of not getting caught on other parts because it loosens.
