Description

【０００１】
【産業上の利用分野】
本発明は、上方より生地に係合して該生地を積載面に押圧するミシンのプレッサ装置に関するものである。
【０００２】
【従来の技術】
従来のミシンのプレッサ装置では、押え台に連結される揺動軸がミシン機枠に固定されたブッシュにより支持されていた（例えば、特許文献１参照。）。そして、押え台の先端に固定された押え金は、押えバネ装置（押え棒）により下方つまり加工品支持部材（ミシンベッドの積載面）側に押圧されている。一般的に、押えバネ装置は二股ロッドと弾性部材とを具備し、押え金はミシン駆動時に送り歯の出没によって揺動軸回りに円弧運動する。
【０００３】
【特許文献１】
実公平６−１６６０４号公報（第２頁左欄、第５図）
【０００４】
【発明が解決しようとする課題】
ところが、従来のミシンのプレッサ装置では、揺動軸を支持するブッシュがミシン機枠に固定されているので、ミシンベッド積載面付近における押え金の円弧軌跡を変更できなかった。その結果、種類や厚さの異なる生地を縫製する際に、押え金が生地搬送の障害となる場合があった。また、この円弧軌跡を変更する為に押え金の固定位置を押え台上でズラすと押え金がミシンの縫製部より外れてしまい、その結果、ミシンによる適切な縫製が行えなくなるという問題があった。従って、本発明の課題は、ミシンベッド積載面付近における押え金の円弧軌跡を容易に変更できるミシンのプレッサ装置を提供することを目的としている。
【０００５】
【課題を解決するための手段】
本発明は、上記目的を達成するために、ミシンアームとミシンベッドよりなるミシン機枠の背面に回転可能に支持されバネにより一方向に付勢される押上げレバーと、該押上げレバーに連結される連杆と、ブッシュに回転可能に支持され一部が連杆に係合する揺動軸と、揺動軸の端部にピンを介して連結され先端に押え金を固定した押え台と、押え台用の案内面を有する二股ロッドと該二股ロッドに係合する弾性部材とを具備した押え棒とを備え、該押え棒により押え台の先端を揺動軸回りで下方に付勢して押え金により生地をミシンベッドの積載面に押圧するミシンのプレッサ装置において、ミシン機枠の背面に着脱可能なブラケットを設け、該ブラケットに前記ブッシュを固定するようにしたことを特徴とする。
【０００６】
なお、二股ロッドの窪みに凹部を設け、該凹部にピンを遊嵌させ、押え台にピン係合用の溝を形成すると共に、ブラケットに対応する揺動軸を設けるのが望ましい。また、揺動軸の端部をクランク片にし、クランク片の基端をミシンアームの左側面より左方に突出させず、押え台との連結をクランク片の先端で行うとよい。
【０００７】
【作用】
本発明によれば、ミシン機枠の背面に着脱可能なブラケットを設け、該ブラケットに前記ブッシュを固定するようにしたので、ミシンベッド積載面付近における押え金の円弧軌跡を容易に変更できる。また、二股ロッドの窪み部に凹部を設け、該凹部にピンを遊嵌させ、押え台にピン係合用の溝を備えると共に、ブラケットに対応する揺動軸を設けるようにすると、二股ロッドの凹部に遊嵌されたピンの下端を押え台のピン係合用溝に係合させることができる。
【０００８】
【発明の実施の形態】
以下、本発明に係る実施の形態を図面を用いて説明する。ミシンのプレッサ装置は、押上げレバー１、連杆２、揺動軸３、押え台４および押え棒５を備える。押上げレバー１は連杆取付け用の孔１ａを有し、該レバー１の基端部はミシン機枠Ｍの背面に段付ネジ６で回転可能に支持されている。バネ７は押上げレバー１と共に段付ネジ６に介装されている。バネ７の一端はミシン機枠Ｍに係止され、他端は押上げレバー１の下部に係止されている。連杆２はフック８と腕９よりなり、フック８は押上げレバー１の孔１ａに取付けられている。腕９には、爪部９ａが形成されると共に孔９ｂが穿設されている。
【０００９】
腕９の孔９ｂには揺動軸３が回転可能に介装される。揺動軸３はブッシュ１０に回転可能に支持され、ブッシュ１０はブラケット１１に固定されている。ブラケット１１はネジ１２でミシン機枠Ｍの背面に取付けられている。つまりブラケット１１はミシン機枠Ｍに対して着脱可能となっており、ブッシュ１０の固定位置をズラして形成された他のブラケット２８（図５参照）と取替えることもできる。また揺動軸３の一方の端部にクランク片３ａが固着され、他方の端部にカラー１３がネジ１４で取付けられている。ブッシュ１０にはバネ１５が介装されている。バネ１５の一端はミシン機枠Ｍに係止され、他端は腕９の下部に係止されている。バネ７，１５の作用により、押上げレバー１は一方向に付勢され、足踏ペダル等で回動された押上げレバー１に復帰力が与えられる。なお、足踏ペダル等で押上げレバー１が回動されると、揺動軸３に固定されたカラー１３の係止部１３ａつまり揺動軸３の一部に腕９の爪部９ａが係合し、揺動軸３が軸心回りに回転する。
【００１０】
揺動軸３のクランク片３ａにはピン１６が虫ネジ１７で固定されている。押え台４は、ピン１６を介して回転可能に揺動軸３のクランク片３ａに連結されている。クランク片３ａの基端はミシンアームＡの左側面ＭＬより左方に突出しないようになされてある。これによりミシンベッドＢの積載面ＢＳ上における省力装置用スペースを確保している。押え台４の先端には押え金４ａがネジ４ｃで固定されている。押え金４ａは、ネジ４ｃの弛緩時に押え台４に対する固定位置を変更できる。押え棒５は押え台４の中途に配置されている。押え棒５は、ミシンアームＡに貫通された筒体１８に設けられ、コイルバネ（弾性部材）１９および二股ロッド２０を有する。コイルバネ１９は筒体１８内に挿入されている。二股ロッド２０は中空になっており、そのロッド２０の下端は窪み２０ａを有する。二股ロッドの窪み２０ａは押え台４の左右面を案内する案内面を有する。
【００１１】
二股ロッド２０の中空部にはコイルバネ１９用の係合片２１が係止具２２で固定されている。この係合片２１の下端は二股ロッドの窪み２０ａより奥深くに位置付けられ、この空間が二股ロッド２０の凹部２０ａａを形成している。二股ロッド２０の凹部２０ａａにはピン２３が遊嵌されている。また、押え台４の上面は溝４ｂを備え、ピン２３の下端が押え台４の溝４ｂに係合するようになしてある。これによりピン２３からの押圧が押え台４の溝４ｂより外れなくなる。なお手動レバー２５は段付ネジ２６を介してミシンアームＡに取付けられている。手動レバー２５の回動操作により、手動レバー２５の爪部２５ａが二股ロッド２０の係止具２２に係合し、二股ロッド２０による押え台４の押圧が解除される。
【００１２】
更にピン２３先端部の左右面を面取りするとともに、この面取り部分２３ａを二股ロッド下端に形成された窪み２０ａの案内面に係合させている。つまり二股ロッド２０について、窪み２０ａにおける案内面の間隔を凹部２０ａの内径より狭くしている。このようにしておくと、手動レバー２５による押え台４の押圧解除時にピン２３が二股ロッド２０より外れない。二股ロッド２０に対するコイルバネ１９の押圧力は調節ネジ２７の旋回操作で調節する。押え棒５は、通常、押え台４の先端を揺動軸回りで下方に付勢する。これにより押え台４の先端に固定された押え金４ａは、生地をミシンベッドＢの積載面ＢＳに押圧する。
【００１３】
本実施の形態においては、ブッシュの固定位置をズラして形成された他のブラケットと取り替えることでミシンベッド積載面付近における押え金の円弧軌跡を変更しているが、これに限定されるわけでない。例えば図６に示されるように、長孔２９ａが形成されたブラケット２９をネジ３０でミシン機枠Ｍに固定するようにしてもよい。そのようにすると、ネジ３０による締付けを弛緩させた時にブラケットの固定位置を長孔２９ａ内で移動でき、ミシンベッド積載面付近における押え金の円弧軌跡を変更できる。またブラケット２８を取替える際、図７に示されるように、ブラケット２８に対応する揺動軸つまりクランク片３２ａを変更した揺動軸３２も併せて取替えると、二股ロッド２０の凹部に遊嵌されたピン２３の下端を押え台４のピン係合用溝４ｂに係合させることができる。
【００１４】
【発明の効果】
以上のように、本発明によれば、ミシンベッド積載面付近における押え金の円弧軌跡を容易に変更できるので、種類や厚さの異なる生地を縫製する場合であっても押え金が生地搬送の障害とならない。また、二股ロッドの凹部に遊嵌されたピンの下端を押え台のピン係合用溝に係合させるので、ミシン駆動時にピンの下端が押え台上で前後にスライドせず、押え棒による押圧力の変動を最小限にすることができる。さらに、ピン下端を押え台上で前後にスライドしないようにすることによりピン下端の摩耗を減少できる。なおクランク片の基端をミシンアームの左側面より左方に突出させないようにすると、ミシンベッドの積載面上における省力装置用スペースを確保することができる。

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The presser device of the sewing machine includes a lifting lever 1, a connecting rod 2, a swing shaft 3, a holding table 4, and a holding rod 5. The push-up lever 1 has a hole 1a for attaching a connecting rod, and the base end of the lever 1 is rotatably supported on the back surface of the machine frame M by a stepped screw 6. The spring 7 is provided on the stepped screw 6 together with the push-up lever 1. One end of the spring 7 is locked to the sewing machine frame M, and the other end is locked to a lower portion of the push-up lever 1. The connecting rod 2 includes a hook 8 and an arm 9, and the hook 8 is attached to a hole 1 a of the lifting lever 1. The arm 9 is formed with a claw 9a and a hole 9b.
[0009]
The swing shaft 3 is rotatably interposed in the hole 9 b of the arm 9. The swing shaft 3 is rotatably supported by a bush 10, and the bush 10 is fixed to a bracket 11. The bracket 11 is attached to the back of the machine frame M with screws 12. That is, the bracket 11 is detachable from the sewing machine frame M, and can be replaced with another bracket 28 (see FIG. 5) formed by shifting the fixing position of the bush 10. A crank piece 3 a is fixed to one end of the swing shaft 3, and a collar 13 is attached to the other end by a screw 14. A spring 15 is interposed in the bush 10. One end of the spring 15 is locked to the sewing machine frame M, and the other end is locked to the lower part of the arm 9. By the action of the springs 7 and 15, the push-up lever 1 is urged in one direction, and a restoring force is applied to the push-up lever 1 rotated by a foot pedal or the like. When the push-up lever 1 is rotated by a foot pedal or the like, the claw portion 9a of the arm 9 is engaged with the locking portion 13a of the collar 13 fixed to the swing shaft 3, that is, a part of the swing shaft 3. At the same time, the swing shaft 3 rotates around the axis.
[0010]
A pin 16 is fixed to a crank piece 3 a of the swing shaft 3 with a screw 17. The holding table 4 is rotatably connected to the crank piece 3 a of the swing shaft 3 via a pin 16. The base end of the crank piece 3a does not protrude leftward from the left side surface ML of the sewing machine arm A. This secures a space for the power saving device on the loading surface BS of the sewing machine bed B. A presser foot 4a is fixed to the tip of the presser stand 4 with a screw 4c. The presser foot 4a can change the fixed position with respect to the presser base 4 when the screw 4c is loosened. The presser bar 5 is arranged in the middle of the presser table 4. The presser bar 5 is provided on a cylindrical body 18 penetrated by the sewing machine arm A, and has a coil spring (elastic member) 19 and a forked rod 20. The coil spring 19 is inserted in the cylinder 18. The forked rod 20 is hollow, and the lower end of the rod 20 has a recess 20a. The bifurcated rod recess 20 a has a guide surface for guiding the left and right surfaces of the presser table 4.
[0011]
An engagement piece 21 for the coil spring 19 is fixed to a hollow portion of the forked rod 20 by a locking tool 22. The lower end of the engagement piece 21 is positioned deeper than the recess 20a of the forked rod, and this space forms the recess 20aa of the forked rod 20. A pin 23 is loosely fitted in the recess 20aa of the forked rod 20. The upper surface of the holding table 4 is provided with a groove 4 b, and the lower end of the pin 23 is engaged with the groove 4 b of the holding table 4. As a result, the pressure from the pin 23 does not come off the groove 4b of the holding table 4. The manual lever 25 is attached to the sewing machine arm A via a stepped screw 26. By the rotation operation of the manual lever 25, the claw portion 25a of the manual lever 25 is engaged with the locking member 22 of the forked rod 20, and the pressing of the holding table 4 by the forked rod 20 is released.
[0012]
Further, the left and right surfaces of the tip of the pin 23 are chamfered, and the chamfered portion 23a is engaged with the guide surface of the recess 20a formed at the lower end of the forked rod. That is, in the bifurcated rod 20, the interval between the guide surfaces in the recess 20a is made smaller than the inner diameter of the recess 20a. By doing so, the pin 23 does not come off the forked rod 20 when the manual lever 25 releases the presser table 4. The pressing force of the coil spring 19 on the forked rod 20 is adjusted by turning the adjusting screw 27. The presser bar 5 normally urges the tip of the presser table 4 downward around the swing axis. Thus, the presser foot 4a fixed to the end of the presser table 4 presses the fabric against the loading surface BS of the sewing machine bed B.
[0013]
In the present embodiment, the circular locus of the presser foot near the loading surface of the sewing machine bed is changed by replacing the fixing position of the bush with another bracket formed by shifting the position, but the present invention is not limited to this. . For example, as shown in FIG. 6, the bracket 29 having the elongated hole 29 a may be fixed to the machine frame M with a screw 30. By doing so, when the tightening by the screw 30 is loosened, the fixing position of the bracket can be moved within the elongated hole 29a, and the arc locus of the presser near the loading surface of the sewing machine bed can be changed. Also, when the bracket 28 is replaced, as shown in FIG. 7, when the swing shaft corresponding to the bracket 28, that is, the swing shaft 32 in which the crank piece 32a is changed is also replaced, the loose shaft is loosely fitted in the recess of the forked rod 20. The lower end of the pin 23 can be engaged with the pin engaging groove 4b of the holding table 4.
[0014]
【The invention's effect】
As described above, according to the present invention, the arc trajectory of the presser in the vicinity of the sewing machine bed loading surface can be easily changed, so that even when sewing different types or thicknesses of the cloth, the presser foot Does not hinder. Also, since the lower end of the pin loosely fitted in the recess of the forked rod is engaged with the pin engaging groove of the presser table, the lower end of the pin does not slide back and forth on the presser table when the sewing machine is driven, and the pressing force of the presser bar is used. Can be minimized. Further, by preventing the lower end of the pin from sliding back and forth on the holding table, wear of the lower end of the pin can be reduced. If the base end of the crank piece does not protrude leftward from the left side surface of the sewing machine arm, a space for a power saving device on the loading surface of the sewing machine bed can be secured.
