Description

【０００１】
【発明の属する技術分野】
本発明はミシンの近くに配置した状態で使用され且つ糸駒の糸をミシンへ供給する為のスプールスタンドに関し、特に、糸駒から延びる糸を保持する為の構造を改善したものに関する。
【０００２】
【従来の技術】
一般的な家庭用のミシンでは、ミシン本体（アーム部等）に取付けられた糸立て棒に糸駒が着脱自在に装着され、その糸駒から引出された糸が、糸調子器や天秤等を経由する所定の糸供給経路を通って縫針に供給される。しかし、色や太さ等が異なる複数の糸を使って縫製を行う場合等、糸駒を着脱する糸駒交換作業を頻繁に行うことになり非常に不便である。
【０００３】
一方、複数の糸立て棒を有する糸駒支持台や、糸駒から引出された糸を案内しミシンの糸供給経路に導入させる為のガイド部材等を固定的に設けたミシンでは、複数の糸を使って縫製を行う場合等でも、使用する複数の糸駒を一旦装着しておけば、糸駒交換作業が不要になるため便利であるが、ミシンが大型化するため持運びや収納の際に不便であるし、糸駒支持台やガイド部材等については、それを設けたミシンにしか使用することができない。
【０００４】
そこで、従来、複数の糸立て棒を有する支持部材（糸駒支持台）、複数の糸立て棒に装着された複数の糸駒から引出された糸を夫々案内する複数のガイド孔を有するガイド部材、支持部材とガイド部材を所定の高さ位置で支持する脚部等を備え、種々のミシンに使用可能なスプールスタンドが実用に供されている。
【０００５】
実公平３−３３３３６号公報のスプールスタンドでは、脚部が円板状の基台と基台に立設された支柱を有し、水平方向に長いガイド部材（糸案内）と支持部材（糸立台）とが略上下に且つ平行に配設され、支柱の途中部に支持部材の長さ方向一端部の筒部が外嵌されネジ止めされ、支柱の上端部分にガイド部材の長さ方向一端部の筒部が外嵌されネジ止めされている。
【０００６】
前記支持部材の幅方向中央部には立垂壁が設けられ、その立垂壁の上端部分に糸支え板の幅方向一端部分が反転可能に枢支され、その糸支え板の幅方向他端部分に、複数の糸駒から延びる糸を夫々保持可能な複数のコイル状の糸保持部材が取付けられている。
【０００７】
実公昭６０−６０５０号公報のスプールスタンドでは、脚部が円板状の基台と基台に立設された支柱を有し、水平方向に長い帯板状のガイド部材（水平アーム）と支持部材（載置台）とが略上下に且つ平行に配設され、支柱の途中部にガイド部材の長さ方向中央部分が固定され、支柱の上端部にガイド部材の長さ方向中央部分が固定され、支柱の支持部材とガイド部材との間の部位に、アーム部材を介して第２ガイド部材が取付けられている。
【０００８】
第２ガイド部材には、前記ガイド部材に案内され略下方へ屈曲して延びる複数の糸を、夫々案内する複数のガイド孔が形成されている。第２ガイド部材には１対の糸止め片からなる糸止め体が取付けられ、これら１対の糸止め片に複数の糸保持部が夫々形成され、これら１対の糸止め片の複数対の糸保持部により、複数の糸駒から延びる糸を夫々保持可能に構成してある。
【０００９】
【発明が解決しようとする課題】
実公平３−３３３３６号公報のスプールスタンドでは、糸支え板に取付けた糸保持部材自体で、糸駒から延びる糸を保持するため、コイル状の比較的長い糸保持部材を設けなければならないし、糸保持部材の糸支え板への取付けについても、糸支え板を切欠いて糸保持部材を配設し、そのコイル状の端部が糸支え板に突刺され固着されているため、糸駒から延びる糸を保持する為の構造が複雑化し製作コストも高価になる。
【００１０】
しかも、このスプールスタンドでは、糸保持部材を糸駒の近くに設け、糸駒から延びる糸を直接、つまりガイド孔に糸掛けしないで保持するため、糸替えする度に、使用する糸駒から延びる糸をガイド孔に糸掛けしなければならないし、そのガイド孔には両手を使って糸通して糸掛けしなければならないため煩雑であるため、糸替え作業が非常に面倒になる。
【００１１】
実公昭６０−６０５０号公報のスプールスタンドでは、１対の糸止め片を有する糸止め体が設けられ、それら１対の糸止め片には複数の糸保持部が夫々形成され、更には、糸止め体には第２ガイド部材への取付けの為の複数の係合爪等も形成されているため、糸駒から延びる糸を保持する為の構造が非常に複雑化し製作コストが高価になる。また、前記公報と同様に、ガイド孔には両手を使って糸通して糸掛けしなければならないため煩雑である。しかも、ガイド部材が帯板状に構成され強度が弱いため、例えば、作業者が水平方向にセットされたガイド部材の端部付近に手を掛けると、ガイド部材が折損し易いという問題がある。
【００１２】
また、従来のスプールスタンドでは、糸保持部に保持されている糸を取外す場合、糸掛けした略逆の手順で行わなければならないが、糸保持部に糸を保持させる際の糸掛け（移動）方向が指示されていないため、糸保持部に保持されている糸を容易に取外すことができないものがあり、この場合、糸保持部に糸が絡まるという虞もある。
【００１３】
本発明の目的は、スプールスタンドにおいて、糸を保持する為の構造を簡単化し製作コストを低減すること、糸替え作業を簡単に行えるようにすること、糸を保持部へ保持させる際に所定の糸掛け手順で行えるようにすること、ガイド部材の強度を高めること、等である。
【００１４】
【課題を解決するための手段】
請求項１のスプールスタンドは、ミシンの近くに配置した状態で使用され且つミシンに供給する為に糸駒から引き出された糸を案内するガイド部材を備えたものにおいて、前記ガイド部材に、前記糸を掛けた状態で案内する複数のガイド部と、それらガイド部の各々の近傍において前記糸を保持するための複数の糸保持部とを配列し、前記複数の糸保持部は、それぞれ前記ガイド部の配列方向と交差する方向にガイド部材本体から延びる装着部本体と、その装着部本体の端部から外側に突出した止め部とを有し、前記各糸保持部の前記装着部本体には、それぞれ前記止め部とガイド部材本体との間においてリング状の弾性体を着脱可能に外装装着し、前記各糸保持部においてそれぞれその糸保持部と前記弾性体との間で前記糸を挟持保持するように構成したことを特徴とするものである。
【００１５】
このスプールスタンドでは、糸駒から引き出された糸を案内するガイド部材に、前記糸を掛けた状態で案内する複数のガイド部と、それらガイド部の各々の近傍で糸を保持する複数の糸保持部とを配列したので、ガイド部に案内された糸を近傍の糸保持部に直ちに保持することができ、糸替えする度に、糸駒から延びる糸をガイド部に糸通しする必要がなくなり、糸替え作業を非常に簡単に能率的に行うことができる。
しかも、前記各糸保持部は、それぞれ前記ガイド部の配列方向と交差する方向にガイド部材本体から延びる装着部本体と、その装着部本体の端部から外側に突出した止め部とを有し、前記各糸保持部の前記装着部本体には、それぞれ前記止め部とガイド部材本体との間においてリング状の弾性体を着脱可能に外装装着したので、弾性体と糸保持部との間で糸駒から延びる糸を確実に保持することができ、これにより、弾性体を小型でシンプルな構造にすることができ、また、弾性体の糸保持部への取付けや交換も容易になるため、糸駒から延びる糸を保持する為の構造を簡単化でき、糸保持部の装着部本体にリング状のゴム体等からなる弾性体を容易に装着することが可能になり、製作コストを低減することができる。
【００１６】
請求項２のスプールスタンドは、請求項１の発明において、前記弾性体はＯリングであることを特徴とするものである。従って、弾性体として既存の安価なＯリングを採用でき、弾性体が小型でシンプルな構造になり、弾性体を支持する糸保持部の構造も簡単化する。
【００１７】
【００１８】
請求項３のスプールスタンドは、請求項１又は２に記載の発明において、前記ガイド部材に、糸駒から延びる糸を糸保持部へ保持させる際の糸の移動方向を指示する方向指示部を備えたことを特徴とするものである。
【００１９】
このスプールスタンドでは、糸駒から延びる糸を糸保持部へ保持させる際の糸の移動方向を指示する方向指示部を設けたので、糸を糸保持部へ保持させる際に所定の糸掛け手順で行えるようになり、これにより、糸保持部に保持されている糸を、糸掛けした略逆の手順で容易に取外すことができる。ガイド部に案内された糸を糸保持部に保持させるようにすることが可能になり、これにより、糸替えする度に、使用する糸駒から延びる糸をガイド部に糸掛けする必要がなくなるため、糸替え作業を非常に簡単に行うことができる。
【００２０】
請求項４のスプールスタンドは、請求項３の発明において、前記ガイド部と糸保持部と方向指示部とが合成樹脂材料で一体形成されたことを特徴とするものである。従って、射出成形により、ガイド部と糸保持部と方向指示部とを簡単に形成することができ、部品数の少ない簡単な構造になり、製作コストを低減することができる。
【００２１】
請求項５のスプールスタンドは、請求項３又は４の発明において、前記方向指示部が矢印等のマークであることを特徴とするものである。従って、糸駒から延びる糸を糸保持部へ保持させる際の糸の移動方向を、判りやすく確実に指示することができる。
【００２２】
請求項６のスプールスタンドは、請求項３〜５の何れかの発明において、前記ガイド部と糸保持部と方向指示部は、帯板状のガイド部材に設けられたことを特徴とするものである。従って、ガイド部と糸保持部と方向指示部とを有するガイド部材を合成樹脂材料で一体形成することができ、ガイド部材の構造を簡単化し、製作コストを低減することができる。
【００２３】
請求項７のスプールスタンドは、請求項６の発明において、前記ガイド部材は、その長さ方向へ延び且つガイド部と糸保持部の間に設けられた厚肉部であって、糸駒から延びる糸を糸保持部に保持させる際に、ガイド部から延びる糸の途中部を指で押さえつけることが可能な厚肉部を有するものである。
【００２４】
従って、ガイド部材の強度を高めることができ、例えば、作業者が水平方向にセットされたガイド部材の端部付近に手を掛けても、ガイド部材が折損しにくく、ガイド部から延びる糸の途中部を厚肉部に指で押さえつけることができるため、糸駒から延びる糸を糸保持部に保持させる際の作業を行い易くなる。
【００２５】
請求項８のスプールスタンドは、請求項７の発明において、前記ガイド部は厚肉部と反対側へ向いた糸導入開口を有することを特徴とするものである。従って、支持部の糸駒から延びる糸を、片手で持ったままでも、糸導入開口からガイド部に非常に簡単に糸掛けすることができる。
【００２６】
【００２７】
【００２８】
【００２９】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照して説明する。
本実施形態は、複数の糸駒を着脱自在に装着し、ミシンの近くに配置した状態で使用可能なスプールスタンドに、本発明を適用した場合の例である。尚、使用可能に配置した状態のスプールスタンドの前後左右を前後左右として説明する。
【００３０】
図１〜図４に示すように、スプールスタンド１は、複数（１０個）の糸駒８を支持可能な支持部材２、支持部材２の上方に配設され支持部材２に支持された複数の糸駒８から上方へ引出された糸９を夫々案内し下方へ屈曲させるガイド部材３、支持部材２に設けられガイド部材３で案内されて下方へ延びる糸９を案内しミシンＭ側へ屈曲させる第２ガイド部材４、ガイド部材３に設けられ複数の糸駒８から延びる糸９を夫々保持可能な複数（１０組）の糸保持機構５、支持部材２及びガイド部材３を所定の高さ位置で支持する脚部６等を備えている。
【００３１】
前記支持部材２は合成樹脂材料で構成され、図１〜図３、図５に示すように、水平方向（左右方向）に長い平面視矩形状の載置面１１を有する載置部１０、載置部１０の端縁部から下方へ屈曲する補強壁部１２，１３等を有する。載置部１０には、複数の糸駒８を夫々立向きで載置支持可能な複数（１０組）の支持部１５が左右方向に千鳥状に設けられ、これら支持部１５に複数（１０本）の糸立棒１６が夫々立設され、載置部１０の水平方向中央部には上下に伸縮可能なロッド状の連結部材１９の下端部が連結されている。
【００３２】
図３、図５に示すように、各支持部１５は、平面視にて糸駒８の鍔部８ａよりも大きな円形をなし、その中心部に糸立棒１６が立設され、糸立棒１６に装着された糸駒８の外周側から中心部に向かって緩やかに窪んだ形状をなしている。尚、支持部１５の中心部分に形成された凹部１５ａに、糸立棒１６の鍔部１６ａが上側から内嵌され、支持部１５の中心部分の下側に一体形成されたボス部１５ｂに、糸立棒１６の鍔部１６ａから下方へ延びる軸部１６ｂが挿入されている。
【００３３】
前記ガイド部材３は、図１、図２、図４に示すように、合成樹脂材料で左右方向に長い帯板状に構成され、支持部材２の前後方向中央部の上側において、支持部材２と左右方向位置を略一致させた状態で配設され、支持部材２に下端部が連結された連結部材１９の上端部に連結されている。
【００３４】
ガイド部材３には、その上下方向中央部付近において、左右方向へ延びる補強用の厚肉部２０が一体形成され、厚肉部２０よりも上側に、糸導入開口２２を夫々有する複数（１０組）のガイド部２１が、図１及び図４に示されるように左右方向に適当間隔おきに配列形成され、これらガイド部２１により、複数の糸駒８から上側へ引出された糸９が、夫々下方へ屈曲するように案内される。
【００３５】
各糸導入開口２２は、ガイド部材３の上端部を切欠くように形成され且つ上側に広がる１対のテーパ部２３と、これらテーパ部２３の間隔が狭まる下端付近とガイド部２１とに連通するスリット２４からなり、厚肉部２０と反対側（上側）に向くように形成されている。また、ガイド部材３の左右方向中央部には、縦向きの厚肉部２５が前記厚肉部２０と交差状に一体形成され、その厚肉部２５の下端部の塊部２６に、連結部材１９の先端部が挿入され固着されている。
【００３６】
ここで、図３、図４に示すように、支持部材２の複数の支持部１５（糸立棒１６）とガイド部材３の複数のガイド部２１とを夫々対応付ける為に、支持部材２とガイド部材３には、複数（１０個）の数字からなる指標部「１」、「２」、「３」・・・が夫々設けられている。これら指標部「１」、「２」、「３」・・・は、支持部材２とガイド部材３に夫々一体形成され、対応する支持部１５とガイド部２１には同じ数字の指標部が印されている。尚、指標部としては、数字以外に、例えば、アルファベット等の種々の文字や記号等を適用可能である。
【００３７】
前記第２ガイド部材４は金属材料で構成され、図１〜図３に示すように、支持部材２（ガイド部材３）の左右方向中央付近に１つだけ配設されている。第２ガイド部材４は上下に長く、上端部分に前側へ鍵型に屈曲した糸掛け部２８が形成され、下端部分が支持部材２の載置部１０に挿入状に固着されている。
【００３８】
前記複数の糸保持機構５は、図１、図４、図７、図８に示すように、ガイド部材３の下端部側において、複数のガイド部２１の下側近傍に夫々設けられ、各糸保持機構５は、正面視にて略逆Ｔ型の装着部３１を有する糸保持部３０（弾性体支持部）と、装着部３１に装着された（弾性体支持部に支持された）リング状の弾性ゴム体であるＯリング３２とを有する。
【００３９】
図６に示すように、装着部３１はガイド部材３と一体形成され、ガイド部材３からガイド部２１の配列方向（左右方向）と交差する下方へ延びる装着部本体３３と、装着部本体３３の下部から左右両側へ突出したゴム止め部（止め部）３４を有する。装着部本体３３とゴム止め部３４の前後幅はガイド部材３と同じで、装着部本体３３の左右長はその前後幅よりも長く、Ｏリング３２は装着部本体３３に略楕円状に弾性変形した状態で外装されている。
【００４０】
ゴム止め部３４において、装着部本体３３から右側へ突出した部分は、ゴム止め部３４から左側へ突出した部分よりも長く、また、装着部本体３３から右側へ突出した部分の右端上部には、右側下がりのテーパ部３４ａが形成され、これにより、装着部３１にＯリング３２を着脱し易すくなる。尚、ガイド部材３においてゴム止め部３４の上側の部位は糸保持部３０に含まれる。
【００４１】
ここで、図４、図７、図８に示すように、ガイド部材３の前面の厚肉部２０よりも下側には、複数の糸駒８から延びる糸９を複数の糸保持部３０へ保持させる際に、糸９の移動方向を指示する複数の矢印マークからなる方向指示部「←」が、ガイド部材３と一体形成され設けられている。
【００４２】
前記脚部６は、図１、図２に示すように、合成樹脂製の基台４０と、基台４０に立設された金属製（例えば、ステンレス製）の角筒部材４１からなり、角筒部材４１の下端部が、基台４０の上面部の水平方向中央部に設けられた連結筒部４２に挿入されて連結され、角筒部材４１の上端部が、支持部材２の下面部の前後方向中央部且つ左右方向中央部よりも右側に設けられた連結筒部４３に挿入され連結されている。
【００４３】
即ち、支持部材２とガイド部材３は、脚部６（支柱４１）に対してその左端部から脚部６までの長さが右端部から脚部６までの長さよりも長い非対称位置に取付けられている。脚部６の基台４０の前端部には、ミシンの後側近くに配置した状態でミシンの外形に沿う形状の対向部４５が形成され、基台４０の右前端部には、対向部４５よりも前側へ突出する位置決め部４６が形成されている。
【００４４】
スプールスタンド１の作用・効果について説明する。
スプールスタンド１に糸駒８と糸駒８から延びる糸９をセットする場合、糸駒８を支持部材２の糸立棒１６に装着して支持部１５に支持させ、その糸駒８から延びる糸９をガイド部材３のガイド部２１に糸掛けする。この場合、同じ数字の指標部が印された対応する支持部１５とガイド部２１とに、糸駒８とその糸駒８から延びる糸９をセットする。
【００４５】
セットした糸９を使用しない場合には、その糸９を案内しているガイド部２１の下側の糸保持機構５に保持する。この場合、図７に示すように、先ず、ガイド部２１から延びる糸９の途中部を厚肉部２０に一方の指で押さえつけ、その糸８の先端側を持って、糸保持機構５よりも後側へ移動させた状態から、方向指示部「←」の指示する方向（左側）へ移動させ、次に、糸保持機構５よりも前側へ移動さてから右側へ移動させ、その後、糸保持機構５よりも後側へ移動させてから下側へ導く。
【００４６】
すると、図８に示すように、糸９はガイド部材３の下端部の糸保持部３０とＯリング３２との間で挟持された状態になり、次に、はさみ５０等を使って、糸保持部３０から延びる糸９を僅かに残して切断する。尚、糸９を糸保持機構５に保持させる場合、図７の示すように、糸８を持った指を糸保持機構５の下側において矢印に示す方向へ移動させることで可能になり、方向指示部「←」はその糸保持操作の移動開始方向を示すことになる。
【００４７】
図９、図１０に示すように、ベッド部５０と脚柱部５１とアーム部５２と布保持枠５３等を有するミシンＭにスプールスタンド１を使用する場合、基台４０の位置決め部４６を、ベッド部５０の後右端部に当接させて位置決めするとともに、対向部４５をベッド部５０の後面に当接させた状態に配置する。尚、本実施形態のスプールスタンド１では、特に、本実施形態の対向部４５や位置決め部４６等は、ミシンＭのような後部外形を有するミシンに使用する場合に有利になる形状に構成されている。
【００４８】
支持部材２の使用する１つの糸駒８から引出された糸９は、ガイド部材３のガイド部２１に案内されて下方へ屈曲して延び、第２ガイド部材４に案内されて、ミシンＭの糸供給経路側へ屈曲し、その糸供給経路を通って縫針に供給される。糸替えする場合、使用していた糸９をミシンＭの糸供給経路から取外した後、その糸９を保持部機構５で保持し、次に使用する糸９を糸保持機構５から取外し、ミシンＭの糸供給経路にセットする。
【００４９】
このスプールスタンド１によれば、各糸保持機構５にＯリング３２とＯリング３２を支持する糸保持部３０とを設けたので、Ｏリング３２と糸保持部３０との間で糸駒８から延びる糸９を確実に保持することができ、Ｏリング３２と糸保持部３０を小型でシンプルな構造にすることができ、また、Ｏリング３２の糸保持部３０の装着部３１への取付けも容易になるため、糸保持機構５の構造を簡単化することができ、製作コストを低減することができる。
【００５０】
複数の糸保持機構５（糸保持部３０）を複数のガイド部２１の下側近傍に夫々設けたので、ガイド部２１に案内された糸９を糸保持機構５で保持することができるため、糸替えする度に、使用する糸駒８から延びる糸９をガイド部２１に糸掛けする必要がなくなるため、糸替え作業を非常に簡単に行うことができる。
【００５１】
糸駒８から延びる糸９を糸保持部３０へ保持させる際の糸９の移動方向を指示する方向指示部「←」を設けたので、糸９を糸保持部３０へ保持させる際に所定の糸掛け手順で行えるようになり、これにより、糸保持部３０に保持されている糸９を、糸掛けした略逆の手順で容易に取外すことができる。
【００５２】
ガイド部材３を、ガイド部２１と糸保持部３０と方向指示部「←」とを合成樹脂材料で一体形成して構成したので、ガイド部材３を射出成形により簡単に形成することができ、部品数の少ない簡単な構造になり、製作コストを低減することができる。方向指示部「←」が矢印のマークであるので、糸駒８から延びる糸９を糸保持部３０へ保持させる際の糸９の移動方向を、判りやすく確実に指示することができる。
【００５３】
ガイド部材３に厚肉部２０を設けたので、ガイド部材３の強度を高めることができ、例えば、作業者が水平方向にセットされたガイド部材３の端部付近に手を掛けても、ガイド部材３が折損しにくくなり、また、ガイド部２１から延びる糸９の途中部を厚肉部２０に指で押さえつけることができるため、糸駒８から延びる糸９を糸保持部３０に保持させる際の作業を行い易くなる。
【００５４】
ガイド部２１は厚肉部２０と反対側へ向いた糸導入開口２２を有するので、支持部１５の糸駒８から延びる糸９を、片手で持ったままでも、糸導入開口２２からガイド部２１に非常に簡単に糸掛けすることができる。糸保持部３０は略逆Ｔ型の装着部３１を有するので、その装着部３１にＯリング３２を容易に装着することが可能になる。
【００５５】
尚、脚部６の角筒部材４１が中空になっているため、スプールスタンド１を一層軽量化することができるうえ、角筒部材４１の内部に、予備部品等の種々の部品、部材を収納することが可能になる。
【００５６】
前記実施形態の変形例について説明する。
１〕前記ガイド部材３だけをミシンの近くに単独で配置し、つまり支持部材２等を省略して使用するものに構成してもよい。
２〕前記ガイド部材３において、複数のガイド部２１を省略した帯板部材とし、その帯板部材に複数の糸保持機構５を設けてもよい。
【００５７】
３〕前記Ｏリング３２の代わりに種々のリング状のゴム体を適用可能である。
４〕前記方向指示部を矢印マーク「←」の代わりに、種々の図形としてよい。例えば、図７において、糸保持機構５の下側に記した糸掛け手順を含む矢印を方向指示部としてもよい。この場合、糸掛け手順がより明快に判るようになる。また、方向指示部を矢印マーク等の図形のシール又はそれが印刷されたシールを接着し設けてもよい。
【００５８】
５〕角筒部材４１及び、角筒部材４１の上下両端部が挿入され連結される連結筒部４２，４３の断面形状を、三角形状、長方形状、ベース形状等の他種々の多角形状になるように構成してもよく、これにより、脚部６と支持部材２とを向きを間違えることなく容易に組立てることが可能になる。
【００５９】
６〕脚部６の基台４０の下面に、１又は複数個のゴム足（ゴネ部材）、又は、ゴムシート等の滑り止めシート等を取付けてもよい。糸駒８から延びる糸９は、第２ガイド部材４に案内され左側へ繰出され、その際、スプールスタンド１に左側への力が作用するが、前記ゴム足や滑り止めシートを設けることで、スプールスタンド１が滑って移動するのを確実に防止することができる。
【００６０】
尚、前記実施形態のスプールスタンドは一例を示すものに過ぎず、本発明の趣旨を逸脱しない範囲において種々の変更を付加し、種々のスプールスタンドに本発明を適用できることはいうまでもない。
【００６１】

In a general household sewing machine, a thread spool is detachably attached to a thread spool attached to a sewing machine main body (arm part, etc.), and the thread drawn from the thread spool is used as a thread tensioner, a balance, etc. It is supplied to the sewing needle through a predetermined thread supply path. However, when sewing using a plurality of threads having different colors, thicknesses, etc., it is very inconvenient because the thread piece changing work for attaching and detaching the thread piece is frequently performed.
[0003]
On the other hand, in a sewing machine in which a guide member or the like for guiding a thread drawn from the thread spool and introducing it into the thread supply path of the sewing machine is fixedly provided, Even when sewing using a sewing machine, it is convenient to replace the thread spool once it has been installed, so it is convenient to carry it around. In addition, the thread spool support base and the guide member can be used only for a sewing machine provided with the same.
[0004]
Therefore, conventionally, a support member (yarn piece support base) having a plurality of spool pins, and a guide member having a plurality of guide holes for guiding the yarns drawn from the plurality of yarn spools attached to the plurality of spool pins, respectively. In addition, a spool stand that is provided with a leg portion that supports the support member and the guide member at a predetermined height position and that can be used for various sewing machines has been put to practical use.
[0005]
In the spool stand disclosed in Japanese Utility Model Publication No. 3-33336, the leg portion has a disk-shaped base and a support column erected on the base, and a horizontally long guide member (thread guide) and support member (thread stand). And a cylindrical portion of one end in the length direction of the support member are externally fitted and screwed to the middle portion of the column, and one end in the length direction of the guide member is fixed to the upper end portion of the column. The cylindrical part of the part is externally fitted and screwed.
[0006]
