Description

【0001】
【発明が属する技術分野】
本発明は、針の上下動に調時して布を張設した刺繍枠をX方向とY方向とに駆動して刺繍模様を形成するようにした刺繍ミシンの刺繍枠に関するものである。
【0002】
【従来の技術】
従来の刺繍枠では、刺繍ミシンのキャリッジに取り付けるための取り付け部と、布を張るための枠部を備えた外枠と、該外枠との間で布を張るための内枠とにより、刺繍枠を構成していた。この刺繍枠をキャリッジへ簡単な操作で取り付けられるようにする技術については、本願出願人による、実開平6−12496号で提案し、実用に供されている。
そのキャリッジの取り付け部の断面は図6に示す如くであり、刺繍枠外枠11には、キャリッジに設けた穴部に係合して位置決めするための一対のガイドピン12と、キャリッジの溝部に係合して、ばね13aの押圧力により、キャリッジに刺繍外枠11を固定するための枠固定ピン13が装着されている。該枠固定ピン13及び一対のガイドピン12はキャリッジの穴部及び溝部に係合するため、刺繍外枠の下面11cより下方に突出している。16は取り付けツマミであって、枠固定ピン13の上端に装着されている。19は枠固定ばねであって、枠固定ピン13に遊嵌しており、常には枠固定ピン13を上方に付勢している。枠固定ピン13の下端は取り付け部11の下面11cから突出している。
【0003】
そして、刺繍外枠に刺繍布を配置し、その上方から刺繍内枠を配置して、刺繍外枠と刺繍内枠とで刺繍布を挟持する。このため、刺繍外枠11は、平らな作業領域に配置して、作業を行うことが望ましいが、前記の枠固定ピン13及び一対のガイドピン12が刺繍外枠の下面11cより下方に突出しているため、刺繍外枠の下面が傾いてしまうこととなり、安定性が悪いこと、また枠固定ピン13及び一対のガイドピン12が作業面を傷付けるなどの問題があった。このため、作業台の端などで、枠固定ピン13及び一対のガイドピン12を作業台から外した位置で刺繍布の装着を行わなければならないなどの欠点があった。
【0004】
そして、これは大きな布に対し、刺繍する場所を調節して取り付ける場合などのように、広い作業台の中央部で自由に位置合わせを行うことに対して障害となる。
【0005】
【発明が解決しようとする課題】
このため、本発明では、広い作業台の中央部でも刺繍外枠が傾かずに済み、自由に位置合わせを行うことができる、刺繍枠を提供することを目的とする。
【0006】
【課題を解決するための手段】
このため、本発明は、刺繍内枠と刺繍外枠で刺繍布を保持するための刺繍枠であって、前記刺繍外枠は前記刺繍内枠との間で刺繍布を張設するための枠部と、該枠部と一体でミシンの刺繍枠駆動手段に連結されたキャリッジに装着するための取り付け部とを備え、該取り付け部には前記キャリッジに設けた穴部に係合して位置決めするための一対のガイドピンと、前記キャリッジの溝部に係合して、ばねの押圧力によりキャリッジに刺繍外枠を固定するための枠固定ピンとを備え、該取り付け部は、前記ガイドピンを前記刺繍外枠の下面より突出しないように上方に移動可能に装着している刺繍枠とすることで、課題を解決することができた。また本発明は、前記ガイドピンは常には前記ガイドピンに遊嵌しているバネの押圧により、前記刺繍外枠の下面より下方に突出している刺繍枠とすることで課題を解決することができた。なお、枠固定ピンは刺繍外枠の下面より上方に配置することで、課題を解決した。
【0007】
【発明の実施の形態】
刺繍外枠の下面から突出するものを排除して、広い作業台のどこでも、刺繍布の取り付けを行えるようにするという目的を、刺繍ミシンの側のキャリッジとの取り付け状態を変えることなく実現した。
【0008】
【実施例】
図1から図5は、本発明装置の1実施例であって、図1は刺繍外枠の平面図、図2は刺繍外枠の側面図、図3は取り付け部の平面図、図4は取り付け部の断面図、図5はガイドピンと枠固定ピンとを刺繍外枠の下面より上方に移動した説明図である。
【0009】
図1において、刺繍外枠1は刺繍内枠との間で刺繍布を張設するための枠部1aと、該枠部1aと一体でキャリッジに装着するための取り付け部1bとが設けられている。
【0010】
図3及び図4において、該取り付け部1bにはキャリッジに設けた穴部に係合して位置決めするための一対のガイドピン2と、キャリッジの溝部に係合して、ばね9の押圧力によりキャリッジに刺繍外枠1を固定するための枠固定ピン3とが設けられている。
【0011】
ガイドピン2は取り付け部1bに上下動可能に嵌合しており、上端にはつば部2aが設けられている。
【0012】
取り付け部1bには溝穴1dが設けられており、ガイドピン2に遊嵌しているばね4をガイドする。更にガイドピン2にEリング5が装着されており、ばね4はEリング5と溝穴1dの底部との間に配置され、常にはEリング5を下方となるように付勢している。従って、常には、ガイドピン2は下方に付勢されて、つば部2aが取り付け部1bの上面に当接して位置決めされており、ガイドピン2の下端2bは取り付け部1bの下面1cより突出している。なお、Eリング5の外形は溝穴1dの内径より小径に形成されている。
【0013】
枠固定ピン3は取り付け部1bに上下動可能に嵌合しており、上端には取り付けツマミ6が設けられている。該取り付けツマミ6にはばねをガイドするための、溝穴6aが設けられており、枠固定ピン3にばね7が遊嵌している。更に枠固定ピン3に円板8が遊嵌しており、ばね7は円板8と溝穴6aの底部との間に配置されている。なお、円板8の外形は溝穴6aの内径より小径に形成されている。
【0014】
9は枠固定ばねであって、枠固定ピン3に遊嵌しており、取り付け部1bと円板8との間に配置され、常には円板8を介してばね7とともに枠固定ピン3を上方に付勢している。枠固定ピン3の下端3aは取り付け部1bの下面1cから突出しない。
【0015】
次に本発明の刺繍布装着時の作用について説明する。図4で示す状態で、刺繍外枠1を平らな作業台の上で作業する場合について説明する。図4の状態で刺繍外枠1を上方から押し下げると、ガイドピン2のばね4が圧縮されてガイドピン2は上方に移動して、図5の如くとなる。これにより、刺繍外枠1の取り付け部1bの下面1cから突出するものはなくなり、平らな面のどこでも作業を行うことができるようになる。
【0016】
このようにした刺繍外枠1の上に刺繍布を配置して、刺繍内枠との間で固定することで、刺繍布を装着する。
【0017】
刺繍布を装着後、刺繍外枠1を作業台から取り上げると、ばね4の付勢により、ガイドピン2が刺繍外枠1の取り付け部1bの下面1cから突出して、図4の如くとなる。この状態で、一対のガイドピン2をキャリッジに設けた穴部に係合して位置決めし、枠固定ピン3をキャリッジの溝部に案内する。次にツマミ6を押し下げると、ばね7が圧縮されて枠固定ピン3が刺繍外枠1の取り付け部1bの下面1cから突出する。次に枠固定ばね9の付勢に抗してツマミ6を押し下げて、下げた位置で回転させて、キャリッジの溝部に係合させ、ツマミ6を開放することにより、枠固定ばね9の付勢により刺繍外枠1をキャリッジに保持させる。なお、枠固定ばね9の付勢により刺繍外枠1をキャリッジに保持させる構造については、先に述べた、実開平6−12496号と同一であるので、説明は省略する。
【0018】
【発明の効果】
以上説明したように本発明によれば、キャリッジに位置決めするための一対のガイドピンと、キャリッジに刺繍外枠を固定するための枠固定ピンとにより、簡単な操作で刺繍外枠をキャリッジに取り付けられるようにすると共に、ガイドピンを刺繍外枠の下面より上方に移動可能としたことにより、広い作業台の中央部でも刺繍外枠が傾かずに済み、自由に位置合わせを行うことができる。更にばねにより上方に移動可能としたことにより、刺繍布装着後は、ばねの付勢により、ガイドピンと枠固定ピンとが突出して、キャリッジに位置決めし、キャリッジに刺繍外枠を固定するために機能することができる。
