Description
本発明は、加工布の厚みが大きい場合であっても、縫製時に加工布をしっかり押さえつけることができ、円滑に加工布を縫針まで送ることができるミシンの布押さえ装置に関する。
The present invention relates to a cloth presser device for a sewing machine that can firmly press the work cloth at the time of sewing and can smoothly feed the work cloth to the sewing needle even when the work cloth is thick.
従来のミシンは、針落ち位置の近傍において、加工布を針板へ押さえつけて縫製しやすくする押さえ金を備えている。従来の押さえ金は、押さえ金の中心が針落ち位置となるように押さえ金を配置し、布送り方向の奥側において、布送り方向と直交する方向を回転軸として回転することが可能に支持する支持軸を備えている。押さえ金の先端部分は下方へと付勢されており、加工布の厚みに応じて先端部分が上下動することにより、加工布を適度に押さえつけている。
The conventional sewing machine has a presser foot that makes it easy to sew by pressing the work cloth against the needle plate in the vicinity of the needle drop position. The conventional presser foot is placed so that the center of the presser foot is at the needle drop position, and supported on the back side in the cloth feed direction so that it can rotate around the direction perpendicular to the cloth feed direction. A support shaft is provided. The tip portion of the presser bar is biased downward, and the tip portion moves up and down according to the thickness of the work cloth, thereby pressing the work cloth appropriately.
しかし、かがり縫いを行う、いわゆるロックミシンでは、加工布を重ね合わせて縫製することから加工布の厚みが大きくなる。したがって、加工布の厚みに応じて押さえ金による加工布の押さえ圧を変更することが好ましい。例えば特許文献１では、被縫布の厚みにより押さえ金による被縫布の押さえ圧を制御する布押さえ圧制御装置が開示されている。特許文献１では、被縫布の厚みの変化を検出し、被縫布の厚みの変化を検出した場合には布押さえ部材（押さえ金）による被縫布の押さえ圧を制御することにより、被縫布を円滑に送りつつ、適度な押さえ圧にて押さえつけている。
However, in a so-called lock sewing machine that performs overlock stitching, the thickness of the work cloth increases because the work cloths are overlapped and sewn. Therefore, it is preferable to change the pressing pressure of the work cloth by the presser according to the thickness of the work cloth. For example, Patent Document 1 discloses a cloth pressing pressure control device that controls the pressing pressure of a cloth to be sewn by a presser foot according to the thickness of the cloth to be sewn. In Patent Document 1, a change in the thickness of the cloth to be sewn is detected, and when a change in the thickness of the cloth to be sewn is detected, the pressure of the cloth to be sewn by the cloth pressing member (presser foot) is controlled. It is pressed down with moderate pressure while feeding the sewing fabric smoothly.
また、特許文献２では、加工布の布厚変化に応じて布押さえ部材による加工布の係止状態を変更する布押さえ装置が開示されている。特許文献２では、布押さえ部材を係止状態として加工布を押さえるように工夫しており、加工布の厚みに応じて布押さえ部材の位置を調整している。
Further, Patent Document 2 discloses a cloth presser device that changes the locked state of the work cloth by the cloth presser member in accordance with the change in the work cloth thickness. In Patent Document 2, the cloth pressing member is devised so as to hold the work cloth in the locked state, and the position of the cloth pressing member is adjusted according to the thickness of the work cloth.
しかし、特許文献１に開示してある布押さえ圧制御装置は、布押さえ部材による被縫布の押さえ圧を制御するものであり、布押さえ部材の先端部分を上下動するために補助バネ押さえ棒を引き上げる又は押し下げることにより、被縫布の布送りを円滑に行うものではない。したがって、特に被縫布の厚みが大きい場合、被縫布を布押さえ部材（押さえ金）の下方へ誘導しにくい、あるいは押さえ圧の大きさによっては、被縫布を円滑に送ることができない恐れがあるという問題点があった。
However, the cloth pressing pressure control device disclosed in Patent Document 1 controls the pressing pressure of the cloth to be sewn by the cloth pressing member, and an auxiliary spring pressing bar for moving the tip portion of the cloth pressing member up and down. The fabric is not smoothly fed by pulling up or pushing down. Therefore, particularly when the thickness of the cloth to be sewn is large, it is difficult to guide the cloth to be sewn below the cloth presser member (presser foot), or the cloth to be sewn cannot be smoothly fed depending on the size of the pressing pressure. There was a problem that there was.
また、特許文献２では、布押さえ部材を係止状態として加工布を押さえるように工夫しており、加工布の厚みに応じて布押さえ部材の位置を調整している。したがって、厚みに応じて布押さえ部材の位置を調整する都度、縫製作業を中断する必要があり、作業工程が煩雑になるという問題点もあった。
Further, in Patent Document 2, the cloth pressing member is devised so as to hold the work cloth in the locked state, and the position of the cloth pressing member is adjusted according to the thickness of the work cloth. Therefore, every time the position of the cloth pressing member is adjusted according to the thickness, it is necessary to interrupt the sewing work, and there is a problem that the work process becomes complicated.
本発明は斯かる事情に鑑みてなされたものであり、厚手の加工布であっても、適度な押圧力で押さえつけることができ、円滑に布送りすることができるミシンの布押さえ装置を提供することを目的とする。
The present invention has been made in view of such circumstances, and provides a cloth presser device for a sewing machine that can be pressed with an appropriate pressing force and can smoothly feed even a thick work cloth. For the purpose.
上記問題を解決するために第１発明に係るミシンの布押さえ装置は、レバーの操作により上下方向へ移動することが可能な押さえ棒と、該押さえ棒の移動方向と同じ方向に移動することが可能なスライドピンを支持する支持部材を介して、前端と後端とが交互に上下動することが可能に、前記押さえ棒の一端に連結されている布押さえ部材と、前記レバーの操作により前記押さえ棒を上昇させた場合に前記スライドピンの上昇を規制する規制部材とを備え、前記スライドピンの一端は、前記布押さえ部材の後端近傍に接触するようにしてあり、前記レバーを上げた場合、前記規制部材が前記スライドピンの他端の延長上に位置するように配置してあり、前記レバーを上げない場合、前記規制部材が前記スライドピンの他端の延長上から離れた位置となるように配置してあることを特徴とする。
In order to solve the above problem, the cloth presser device of the sewing machine according to the first invention is capable of moving in the same direction as the direction of movement of the presser bar and the presser bar that can be moved in the vertical direction by operating the lever. Through a support member that supports a possible slide pin, the front end and the rear end can be alternately moved up and down alternately, and a cloth presser member connected to one end of the presser bar and the lever by operating the lever And a regulating member that regulates the rise of the slide pin when the presser bar is raised, and one end of the slide pin is in contact with the vicinity of the rear end of the cloth holding member, and the lever is raised. In this case, the restricting member is disposed so as to be positioned on the extension of the other end of the slide pin, and when the lever is not raised, the restricting member is separated from the extension on the other end of the slide pin. Characterized in that is arranged so as to position.
第１発明では、レバーの操作により上下方向へ移動することが可能な押さえ棒と、該押さえ棒の移動方向と同じ方向に移動することが可能なスライドピンを支持する支持部材を介して、前端と後端とが交互に上下動することが可能に、押さえ棒の一端に連結されている布押さえ部材と、レバーの操作により押さえ棒を上昇させた場合にスライドピンの上昇を規制する規制部材とを備えている。スライドピンの一端は、布押さえ部材の後端近傍に接触するようにしてあり、レバーを上げた場合、規制部材がスライドピンの他端の延長上に位置するように配置してあるので、スライドピンは所定の高さまでしか上昇しない。したがって、レバーをさらに上げた場合、スライドピンが規制部材に当接するので布押さえ部材の後端が上昇することがなく、押さえ棒のみが上昇するので、布押さえ部材の前端が上昇し、加工布の厚みが大きいときであっても円滑に布押さえ部材の下方へ加工布を誘導することができる。レバーを上げない場合、規制部材がスライドピンの他端の延長上から離れた位置となるように配置してあるので、スライドピンの上昇は規制されない。したがって、布押さえ部材の前端は上昇せず、針板面と略平行な状態で加工布を均等な圧力で針板面へ押さえつけることができ、安定した縫製を行うことが可能となる。
In the first aspect of the present invention, the front end is provided via a holding member that supports a pressing bar that can be moved up and down by operating a lever and a slide pin that can move in the same direction as the movement direction of the pressing bar. A cloth presser member that is connected to one end of the presser bar and a restricting member that restricts the lift of the slide pin when the presser bar is lifted by operating the lever. And. One end of the slide pin is in contact with the vicinity of the rear end of the cloth pressing member, and when the lever is raised, the restricting member is arranged so as to be positioned on the extension of the other end of the slide pin. The pin only rises to a predetermined height. Therefore, when the lever is further raised, the slide pin abuts against the regulating member, so that the rear end of the cloth presser member does not rise, and only the presser bar rises. Therefore, the front end of the cloth presser member rises, and the work cloth Even when the thickness of the cloth is large, the work cloth can be smoothly guided below the cloth pressing member. When the lever is not raised, the restricting member is disposed so as to be positioned away from the extension of the other end of the slide pin, so that the rise of the slide pin is not restricted. Therefore, the front end of the cloth pressing member does not rise, and the work cloth can be pressed against the throat plate surface with a uniform pressure in a state substantially parallel to the throat plate surface, and stable sewing can be performed.
また、第２発明に係るミシンの布押さえ装置は、第１発明において、前記レバーを上げた場合、前記規制部材と前記スライドピンの他端とが当接し、前記スライドピンの一端が前記布押さえ部材の後端を押し下げ、前記布押さえ部材の前端が上方へ移動するようにしてあることを特徴とする。
Further, in the cloth presser device for a sewing machine according to the second invention, in the first invention, when the lever is raised, the restricting member and the other end of the slide pin abut, and one end of the slide pin is the cloth presser. The rear end of the member is pushed down, and the front end of the cloth pressing member is moved upward.
第２発明では、レバーを上げた場合、規制部材とスライドピンの他端とが当接し、スライドピンの一端が布押さえ部材の後端を押し下げる。したがって、支持部材と布押さえ部材とが連結している部分を支点として、布押さえ部材の前端が上方へ移動する。これにより、加工布の厚みが大きいときであっても円滑に布押さえ部材の下方へ加工布を誘導することができる。
In the second invention, when the lever is raised, the regulating member and the other end of the slide pin come into contact with each other, and one end of the slide pin pushes down the rear end of the cloth pressing member. Therefore, the front end of the cloth pressing member moves upward with the portion where the support member and the cloth pressing member are connected as a fulcrum. Thereby, even when the thickness of the work cloth is large, the work cloth can be smoothly guided below the cloth pressing member.
また、第３発明に係るミシンの布押さえ装置は、第１又は第２発明において、前記スライドピンの長さは、前記規制部材と前記布押さえ部材の後端との間の距離よりも短くなるようにしてあることを特徴とする。
In the cloth presser device for a sewing machine according to the third invention, in the first or second invention, the length of the slide pin is shorter than the distance between the regulating member and the rear end of the cloth presser member. It is characterized by the above.
第３発明では、スライドピンの長さは、規制部材と布押さえ部材の後端との間の距離よりも短くなるようにしてあるので、レバーを上げた場合、一定の高さまではスライドピンの他端と規制部材とが当接しない。したがって、一定の高さまではスライドピンの上昇は規制されず、針板面と略平行な状態で、布押さえ部材が上昇する。そして、レバーをさらに上げた場合、スライドピンの他端と規制部材とが当接し、布押さえ部材の後端を上昇させずに押さえ棒のみが上昇するので、布押さえ部材の前端が上昇し、加工布の厚みが大きいときであっても円滑に布押さえ部材の下方へ加工布を誘導することができる。
In the third aspect of the invention, the length of the slide pin is shorter than the distance between the regulating member and the rear end of the cloth pressing member. The other end does not come into contact with the regulating member. Accordingly, the lift of the slide pin is not restricted at a certain height, and the cloth pressing member is lifted in a state substantially parallel to the needle plate surface. And when the lever is further raised, the other end of the slide pin and the regulating member abut, and only the presser bar rises without raising the rear end of the cloth presser member, so the front end of the cloth presser member rises, Even when the thickness of the work cloth is large, the work cloth can be smoothly guided below the cloth pressing member.
本発明によれば、スライドピンの一端は、布押さえ部材の後端近傍に接触するようにしてあり、レバーを上げた場合、規制部材がスライドピンの他端の延長上に位置するように配置してあるので、スライドピンは所定の高さまでしか上昇しない。したがって、レバーをさらに上げた場合、スライドピンが規制部材に当接するので布押さえ部材の後端が上昇することがなく、押さえ棒のみが上昇するので、布押さえ部材の前端が上昇し、加工布の厚みが大きいときであっても円滑に布押さえ部材の下方へ加工布を誘導することができる。レバーを上げない場合、規制部材がスライドピンの他端の延長上から離れた位置となるように配置してあるので、スライドピンの上昇は規制されない。したがって、布押さえ部材の前端は上昇せず、針板面と略平行な状態で加工布を均等な圧力で針板面へ押さえつけることができ、安定した縫製を行うことが可能となる。
According to the present invention, one end of the slide pin is in contact with the vicinity of the rear end of the cloth pressing member, and when the lever is raised, the restricting member is disposed on the extension of the other end of the slide pin. Therefore, the slide pin can only rise to a predetermined height. Therefore, when the lever is further raised, the slide pin comes into contact with the regulating member, so that the rear end of the cloth presser member does not rise, and only the presser bar rises. Even when the thickness of the workpiece is large, the work cloth can be smoothly guided below the cloth pressing member. When the lever is not raised, the restricting member is disposed so as to be positioned away from the extension of the other end of the slide pin, so that the rise of the slide pin is not restricted. Therefore, the front end of the cloth pressing member does not rise, and the work cloth can be pressed against the throat plate surface with a uniform pressure in a state substantially parallel to the throat plate surface, and stable sewing can be performed.
以下、本発明に係るミシンの布押さえ装置の実施の形態について図面を参照しながら詳細に説明する。なお、以下の説明において、針板面に沿った平面上において布送り方向に沿った方向をＹ軸方向、布送り方向に直交する方向をＸ軸方向とし、針板面に沿った平面に垂直な方向をＺ軸方向とする。
Hereinafter, embodiments of a cloth presser device for a sewing machine according to the present invention will be described in detail with reference to the drawings. In the following description, the direction along the cloth feed direction on the plane along the needle plate surface is defined as the Y-axis direction, and the direction orthogonal to the cloth feed direction is defined as the X-axis direction, and is perpendicular to the plane along the needle plate surface. This direction is the Z-axis direction.
図１は、本発明の実施の形態に係るミシンの布押さえ装置（以下、布押さえ装置１０）の構成を示す斜視図であり、図２は、本発明の実施の形態に係る布押さえ装置１０の構成を示す、Ｙ－Ｚ平面での側断面図である。
FIG. 1 is a perspective view illustrating a configuration of a cloth presser device (hereinafter referred to as a “cloth presser device 10”) according to an embodiment of the present invention, and FIG. 2 illustrates a cloth presser device 10 according to an embodiment of the present invention. FIG. 6 is a side sectional view in the YZ plane showing the configuration of
図１では、押さえ上げレバー（レバー）１２を２０度上げて、布押さえ部材（押さえ金）１１が針板面１００の上方約６ｍｍに上昇した状態を示している。押さえ上げレバー１２は、押さえ上げレバー１２の動作を制約するレバー制約部材１４と同軸上に固定されており、押さえ上げレバー１２の上下動、すなわち回転に伴って、レバー制約部材１４も回転する。
FIG. 1 shows a state in which the press-up lever (lever) 12 is raised by 20 degrees, and the cloth presser member (presser foot) 11 is raised to about 6 mm above the needle plate surface 100. The press-up lever 12 is fixed coaxially with the lever restricting member 14 that restricts the operation of the press-up lever 12, and the lever restricting member 14 also rotates as the press-up lever 12 moves up and down, that is, rotates.
押さえ上げレバー１２を上げていない場合、ネジリバネ１３の付勢力によりレバー制約部材１４は、回転部材（規制部材）１５の接触面１５１に押しつけられているので、押さえ上げレバー１２は、一定の位置（０度）より下がらない。押さえ上げレバー１２を２０度上げた場合、回転部材１５の爪部１５２がミシン本体のフレーム１６に当接し、回転部材１５のピン当接部１５３が、スライドピン２５の直上まで移動して静止する。
When the press-up lever 12 is not raised, the lever restricting member 14 is pressed against the contact surface 151 of the rotating member (restricting member) 15 by the biasing force of the torsion spring 13, so that the press-up lever 12 is at a certain position ( 0 degrees). When the presser lever 12 is raised by 20 degrees, the claw portion 152 of the rotating member 15 comes into contact with the frame 16 of the sewing machine body, and the pin contact portion 153 of the rotating member 15 moves to just above the slide pin 25 and stops. .
図３は、本発明の実施の形態に係る布押さえ装置１０の回転部材１５の構成を示す二面図である。図３（ａ）は、本発明の実施の形態に係る布押さえ装置１０の回転部材１５の構成を示す、布送り方向の奥側から見た正面図であり、図３（ｂ）は、本発明の実施の形態に係る布押さえ装置１０の回転部材１５の構成を示す、布送り方向に直交する方向から見た側面図である。
FIG. 3 is a two-side view showing the configuration of the rotating member 15 of the cloth presser 10 according to the embodiment of the present invention. Fig.3 (a) is the front view seen from the back | inner side of the cloth feed direction which shows the structure of the rotation member 15 of the cloth pressing device 10 which concerns on embodiment of this invention, FIG.3 (b) is this It is the side view seen from the direction orthogonal to the cloth feed direction which shows the structure of the rotation member 15 of the cloth presser apparatus 10 which concerns on embodiment of invention.
図３に示すように、爪部１５２とピン当接部１５３とは、いずれも回転部材１５の一部であり、爪部１５２がミシン本体のフレーム１６に当接することにより、ピン当接部１５３を所望の位置で静止させることができる。また、回転部材１５は押さえ上げレバー１２の回転軸１５５を回転中心として回転するので、押さえ上げレバー１２の回転（上下動）により、ピン当接部１５３の位置を調整することができる。
As shown in FIG. 3, both the claw portion 152 and the pin contact portion 153 are a part of the rotating member 15, and the pin contact portion 153 is brought into contact with the frame 16 of the sewing machine body. Can be stopped at a desired position. Further, since the rotating member 15 rotates about the rotation shaft 155 of the presser lifting lever 12, the position of the pin contact portion 153 can be adjusted by the rotation (vertical movement) of the presser lifting lever 12.
すなわち、押さえ上げレバー１２を上げた場合、ピン当接部１５３は時計回りに回転し、スライドピン２５の他端の延長上へと移動する。したがって、押さえ上げレバー１２を上げた状態では、スライドピン２５とピン当接部１５３とは当接する。一方、押さえ上げレバー１２を下げた場合、ピン当接部１５３は反時計回りに回転し、スライドピン２５の他端の延長上から離れる。したがって、押さえ上げレバー１２を下げた状態では、スライドピン２５とピン当接部１５３とは当接することがない。
That is, when the press-up lever 12 is raised, the pin contact portion 153 rotates clockwise and moves to the extension of the other end of the slide pin 25. Therefore, when the press-up lever 12 is raised, the slide pin 25 and the pin contact portion 153 come into contact with each other. On the other hand, when the press-up lever 12 is lowered, the pin contact portion 153 rotates counterclockwise and moves away from the extension of the other end of the slide pin 25. Therefore, the slide pin 25 and the pin contact portion 153 do not come into contact with each other when the press-up lever 12 is lowered.
図１及び図２に戻って、押さえ上げレバー１２とレバー制約部材１４とは同軸上に固定されており、押さえ上げレバー１２を上げた場合、レバー制約部材１４の突起部１４１がカム部材１７を押し上げ、カム部材１７は反時計回りに回転する。カム部材１７が反時計回りに回転することで、回転部材１５の突起部１５４が布送り方向の手前側へ押され、回転部材１５は時計回りに回転する。そして、爪部１５２がフレーム１６に当接している状態でカム部材１７の円弧部１７１と突起部１５４とが接触し、爪部１５２はフレーム１６に当接した状態で維持される。
Returning to FIGS. 1 and 2, the press-up lever 12 and the lever restricting member 14 are fixed on the same axis. When the press-up lever 12 is raised, the protrusion 141 of the lever restricting member 14 causes the cam member 17 to move. When pushed up, the cam member 17 rotates counterclockwise. As the cam member 17 rotates counterclockwise, the protrusion 154 of the rotating member 15 is pushed toward the front side in the cloth feeding direction, and the rotating member 15 rotates clockwise. Then, the arc portion 171 of the cam member 17 and the projection 154 come into contact with the claw portion 152 in contact with the frame 16, and the claw portion 152 is maintained in contact with the frame 16.
図４は、本発明の実施の形態に係る布押さえ装置１０の回転部材１５の動作を説明するための、布送り方向に直交する方向から見た側面図である。図４に示すように、押さえ上げレバー１２の回転（上下動）に応じて、回転部材１５も回転するので、接触面１５１ａは接触面１５１ｂへと回転し、接触しているレバー制約部材１４ａはレバー制約部材１４ｂへと回転する。
FIG. 4 is a side view seen from a direction orthogonal to the cloth feeding direction, for explaining the operation of the rotating member 15 of the cloth presser 10 according to the embodiment of the present invention. As shown in FIG. 4, the rotating member 15 also rotates in accordance with the rotation (up and down movement) of the press-up lever 12, so that the contact surface 151 a rotates to the contact surface 151 b, and the lever restricting member 14 a that is in contact is It rotates to the lever restricting member 14b.
レバー制約部材１４の回転により突起部１４１ａがカム部材１７ａを押し上げ、カム部材１７ｂまで回転する。カム部材１７の回転により、カム部材１７ａに接触している回転部材１５の突起部１５４ａがカム部材１７ｂに接触している回転部材１５の突起部１５４ｂへと回転し、爪部１５２ａが爪部１５２ｂへと回転する。爪部１５２ａが爪部１５２ｂへと回転し、ピン当接部１５３ａがピン当接部１５３ｂへと回転して、爪部１５２ｂはフレーム１６に当接する。
The protrusion 141a pushes up the cam member 17a by the rotation of the lever restricting member 14, and rotates to the cam member 17b. The rotation of the cam member 17 causes the protrusion 154a of the rotation member 15 that is in contact with the cam member 17a to rotate to the protrusion 154b of the rotation member 15 that is in contact with the cam member 17b, and the claw 152a is the claw 152b. Rotate to. The claw portion 152a rotates to the claw portion 152b, the pin contact portion 153a rotates to the pin contact portion 153b, and the claw portion 152b contacts the frame 16.
図１及び図２に戻って、押さえ上げレバー１２を２０度よりも大きく上げる場合、押さえ棒２２を支持している押さえ棒抱き１８も上昇する。押さえ棒抱き１８が上昇した場合、スライドピン２５を支持する支持部材２０も上昇する。支持部材２０が上昇した場合、スライドピン２５は、回転部材１５のピン当接部１５３により上方への移動が規制されているため、相対的に下方へ移動し、スライドピン２５の一端が布押さえ部材１１の後端近傍に接触して、布押さえ部材１１の後端を押し下げる。
1 and 2, when the presser lever 12 is raised more than 20 degrees, the presser bar holder 18 supporting the presser bar 22 is also raised. When the presser bar holder 18 is raised, the support member 20 that supports the slide pin 25 is also raised. When the support member 20 is lifted, the slide pin 25 moves relatively downward because the pin abutting portion 153 of the rotating member 15 is restricted so that one end of the slide pin 25 is pressed against the cloth. In contact with the vicinity of the rear end of the member 11, the rear end of the cloth pressing member 11 is pushed down.
布押さえ部材１１は、支持部材２０とネジリバネ２１を介して押さえ棒２２の一端に連結されている。すなわち、スライドピン２５により、布押さえ部材１１の後端が押し下げられない場合には、ネジリバネ２１の付勢力により、布押さえ部材１１の前端は押し下げられており、布送りされる加工布を適度に押さえつけることができる。
The cloth presser member 11 is connected to one end of the presser bar 22 through a support member 20 and a torsion spring 21. That is, when the rear end of the cloth presser member 11 is not pushed down by the slide pin 25, the front end of the cloth presser member 11 is pushed down by the biasing force of the torsion spring 21, and the work cloth fed by the cloth is appropriately pressed. Can be pressed down.
スライドピン２５により、布押さえ部材１１の後端が押し下げられた場合、ネジリバネ２１の付勢力に反して、支持部材２０との連結部分を回転中心（支点）として布押さえ部材１１の前端が上方へと移動する。これにより、例えば加工布の厚みが大きい場合であっても、押さえ上げレバー１２を上げて布押さえ部材１１の前端を上方へ移動させておくことにより、加工布を布押さえ部材１１の下方に円滑に誘導することが可能となる。
When the rear end of the cloth pressing member 11 is pushed down by the slide pin 25, the front end of the cloth pressing member 11 moves upward with the connecting portion with the support member 20 as the rotation center (fulcrum) against the urging force of the torsion spring 21. And move. Thereby, even when the thickness of the work cloth is large, for example, the work cloth is smoothly moved below the cloth presser member 11 by raising the press-up lever 12 and moving the front end of the cloth presser member 11 upward. It becomes possible to guide to.
なお、スライドピン２５の長さは、回転部材（規制部材）１５のピン当接部１５３と布押さえ部材１１の後端との間の距離よりも短いことが好ましい。スライドピン２５の長さを、ピン当接部１５３と布押さえ部材１１の後端との間の距離よりも短くすることで、押さえ上げレバー１２を上げた場合であっても、一定の高さまではスライドピン２５の他端はピン当接部１５３に当接しない。本実施の形態では、２０度まではスライドピン２５の他端はピン当接部１５３に当接しない。したがって、押さえ上げレバー１２を上げた場合であっても、一定の高さまでは針板面１００と略平行な状態で、布押さえ部材１１が上昇する。
In addition, it is preferable that the length of the slide pin 25 is shorter than the distance between the pin contact part 153 of the rotation member (regulation member) 15 and the rear end of the cloth pressing member 11. Even when the press-up lever 12 is raised by making the length of the slide pin 25 shorter than the distance between the pin contact portion 153 and the rear end of the cloth presser member 11, the height of the slide pin 25 is kept constant. Then, the other end of the slide pin 25 does not come into contact with the pin contact portion 153. In the present embodiment, the other end of the slide pin 25 does not contact the pin contact portion 153 until 20 degrees. Therefore, even when the press-up lever 12 is raised, the cloth presser member 11 is raised in a state of being substantially parallel to the throat plate surface 100 at a certain height.
そして、押さえ上げレバー１２をさらに上げた場合、スライドピン２５の他端とピン当接部１５３とが当接し、布押さえ部材１１の後端を押し下げつつ押さえ棒２２のみが上昇するので、布押さえ部材１１の前端が上方へ移動し、加工布の厚みが大きいときであっても円滑に布押さえ部材１１の下方へ加工布を誘導することができる。
When the press-up lever 12 is further raised, the other end of the slide pin 25 and the pin contact portion 153 come into contact with each other, and only the presser bar 22 is raised while pushing down the rear end of the fabric presser member 11. Even when the front end of the member 11 moves upward and the thickness of the work cloth is large, the work cloth can be smoothly guided to the lower side of the cloth pressing member 11.
また、押さえ上げレバー１２を上げない場合、回転部材（規制部材）１５のピン当接部１５３が、スライドピン２５の他端の延長上から離れた位置となるように配置してあるので、スライドピン２５の上昇は規制されない。したがって、厚みが大きい加工布が布押さえ部材１１の下方に誘導されている場合であっても、押さえ棒２２のバネ１９の付勢力により布押さえ部材１１を押し下げ、布押さえ部材１１の前端が上昇せず、針板面１００と略平行な状態で加工布を針板面１００へ押さえつけることができ、安定した縫製を行うことが可能となる。
Further, when the press-up lever 12 is not raised, the pin abutting portion 153 of the rotating member (regulating member) 15 is disposed so as to be away from the extension of the other end of the slide pin 25. Ascent of the pin 25 is not restricted. Therefore, even when a thick work cloth is guided below the cloth pressing member 11, the cloth pressing member 11 is pushed down by the biasing force of the spring 19 of the pressing bar 22, and the front end of the cloth pressing member 11 is raised. Therefore, the work cloth can be pressed against the throat plate surface 100 in a state substantially parallel to the throat plate surface 100, and stable sewing can be performed.
以上のように、本実施の形態によれば、スライドピン２５の一端は、布押さえ部材１１の後端近傍に接触するようにしてあり、レバー１２を上げた場合、規制部材（回転部材）１５がスライドピン２５の他端の延長上に位置するように配置してあるので、スライドピン２５は所定の高さまでしか上昇しない。したがって、レバー１２をさらに上げた場合、スライドピン２５が規制部材１５に当接するので布押さえ部材１１の後端が上昇することがなく、押さえ棒２２のみが上昇するので、布押さえ部材１１の前端が上昇し、加工布の厚みが大きいときであっても円滑に布押さえ部材１１の下方へ加工布を誘導することができる。レバー１２を上げない場合、規制部材１５がスライドピン２５の他端の延長上から離れた位置となるように配置してあるので、スライドピン２５の上昇は規制されない。したがって、布押さえ部材１１の前端は上昇せず、針板面１００と略平行な状態で加工布を均等な圧力で針板面１００へ押さえつけることができ、安定した縫製を行うことが可能となる。
As described above, according to the present embodiment, one end of the slide pin 25 is in contact with the vicinity of the rear end of the cloth pressing member 11, and when the lever 12 is raised, the regulating member (rotating member) 15. Is positioned so as to be located on the extension of the other end of the slide pin 25, the slide pin 25 can only rise to a predetermined height. Therefore, when the lever 12 is further raised, the rear end of the cloth presser member 11 does not rise and only the presser bar 22 rises because the slide pin 25 comes into contact with the regulating member 15. Even when the thickness of the work cloth is large, the work cloth can be smoothly guided below the cloth pressing member 11. When the lever 12 is not raised, the restricting member 15 is disposed so as to be away from the extension of the other end of the slide pin 25, and therefore, the ascent of the slide pin 25 is not restricted. Therefore, the front end of the cloth pressing member 11 does not rise, and the work cloth can be pressed against the throat plate surface 100 with an equal pressure in a state substantially parallel to the throat plate surface 100, and stable sewing can be performed. .
その他、本発明の趣旨を逸脱しない範囲において上記実施の形態に種々の変更を付加した形態で実施することが可能である。
In addition, the present invention can be implemented in a form in which various modifications are added to the above-described embodiment without departing from the spirit of the present invention.
