しかしながら、かかる従来の装置においては、糸通し部材が揺動してそれに応じて糸通しピンが針に接近したときに、糸通しピンが針穴をうまく通過しない場合がある。このような場合に、糸通し部材を無理に操作すると、糸通しピンが耐えられず、曲がって破損するというおそれがある。   However, in such a conventional apparatus, when the threading member swings and the threading pin approaches the needle accordingly, the threading pin may not pass through the needle hole well. In such a case, if the threading member is forcibly operated, the threading pin cannot endure and may be bent and damaged.

本発明はかかる課題に鑑みなされたもので、糸通しピンが針穴を通過しないときでも糸通しピンの破損を防止することができる針糸通し装置を提供することをその目的とする。   The present invention has been made in view of such a problem, and an object thereof is to provide a needle threading device that can prevent the threading pin from being damaged even when the threading pin does not pass through the needle hole.

上記目的を達成するために、本発明の第1の態様は、針挿入穴と、該針挿入穴に対して角度を持った糸挿入スリットとを有する針受部材と、
前記針受部材に対して離反した位置と接近した位置との間で揺動可能となっており、離反した位置から接近した位置へと揺動するときに、前記針挿入穴に挿入された針の針穴に、前記糸挿入スリットに挿入された糸を押し出し可能な糸通しピンを有する、糸通し部材と、
を備えた針糸通し装置において、
前記糸通しピンは、前記糸通し部材の本体に対して一定の揺動範囲内で揺動可能となっており、前記糸通し部材は、さらに前記糸通しピンを前記本体に対して前記針受部材に接近する方向に付勢する付勢部材を備えることを特徴とする。
In order to achieve the above object, a first aspect of the present invention includes a needle receiving member having a needle insertion hole and a thread insertion slit having an angle with respect to the needle insertion hole,
The needle inserted into the needle insertion hole when swinging from a position separated from the needle receiving member to a position approached from the separated position. A threading member having a threading pin capable of pushing out the thread inserted into the thread insertion slit in the needle hole of

糸通し部材42の針受部材34に対する離反する位置から接近する位置への揺動運動の際に、糸通しピン部品56の糸通しピン56bは、前記針受部品36、38の突出部36d、38dの対向面の間に形成される隙間から、針挿入穴34cを形成する長溝部36c、38cの基端部を通過し、抜け穴34gを構成する凹部36g、38gまでを往復運動することができる。   During the swinging movement of the threading member 42 from the position away from the needle receiving member 34 to the approaching position, the threading pin 56b of the threading pin component 56 is formed by the protruding portions 36d of the needle receiving components 36, 38. It is possible to reciprocate from the gap formed between the opposing surfaces of 38d to the recesses 36g and 38g constituting the through hole 34g through the proximal end portions of the long groove portions 36c and 38c forming the needle insertion hole 34c. .

糸通し部材42をバネ58の付勢力に抗して、最大限、針受部材34に接近させたときに、糸通し本体部品46、48の先端部に形成されて径方向及び先端方向に突出する突出部46g、48gが、前記針受部品36、38の突出部36d、38dに接近する。   When the threading member 42 is brought close to the needle receiving member 34 against the urging force of the spring 58, the threading member 42 is formed at the distal ends of the threading main body components 46 and 48 and protrudes in the radial direction and the distal direction. The projecting portions 46g and 48g that come close to the projecting portions 36d and 38d of the needle receiving parts 36 and 38.

尚、バネ60とバネ58とでは、バネ58のバネ力の方が大きくなるように設定されている。   The spring 60 and the spring 58 are set so that the spring force of the spring 58 is larger.

また、糸通し本体部品46、48のそれぞれの対向面には抜け止め突起46f、48fが形成される。   Also, retaining projections 46f and 48f are formed on the opposing surfaces of the threading main body components 46 and 48, respectively.

さらに、針受部品36、38の第2凹部36m、38mに形成された軸受部に軸受されて、保護カバー66が針受部品36、38に取り付けられる。   Further, the protective cover 66 is attached to the needle receiving parts 36 and 38 by being supported by bearings formed in the second recesses 36 m and 38 m of the needle receiving parts 36 and 38.

保護カバー66は、一対の大きくU字状に折曲がった脚部66a、66aと、脚部66aと反対側で小さく折れ曲がった頭部66bとを備え、頭部66bの中心には上下に延びるスリット66cが形成されている。脚部66a、66aは、針受部品36、38の第2凹部36m、38m内に形成された軸受部に軸受されて、針受部品36、38に取り付けられる。保護カバー66は、その弾性により屈曲するように変形可能となっている。頭部66bの折れ曲がった端部には小突起66dが突設されている。   The protective cover 66 includes a pair of large U-shaped leg portions 66a and 66a, and a head portion 66b bent slightly on the opposite side of the leg portion 66a, and a slit extending vertically in the center of the head portion 66b. 66c is formed. The leg portions 66a, 66a are attached to the needle receiving components 36, 38 by being supported by bearings formed in the second recesses 36m, 38m of the needle receiving components 36, 38. The protective cover 66 can be deformed so as to be bent due to its elasticity. A small protrusion 66d protrudes from the bent end of the head 66b.

保護カバー66が針受部品36、38に取り付けられている状態で、保護カバー66の頭部66bと針受部品36、38との間には糸挿入スリット34eに連続する隙間が形成される。   In a state where the protective cover 66 is attached to the needle receiving parts 36 and 38, a gap that is continuous with the thread insertion slit 34e is formed between the head 66b of the protective cover 66 and the needle receiving parts 36 and 38.

以上のように構成される針糸通しユニット12において、不使用時には、図2及び図5に示すようにカバー32は、針受部材34の大部分を覆った位置(拘束位置)にあり、且つ、糸通し部材42は、糸通し本体部品46、48の突出部46g、48g以外の部分は、カバー32によって覆われている。このため、糸通し部材42は、バネ58の付勢力が封じられており、針受部材34に接近した位置で拘束され、針受部材34と共にカバー32内に収まっている。従って、この状態で針糸通しユニット12をコンパクトに収納することができる。このとき、ピン組立体50の糸通しピン56bは、図5に示すように、保護カバー66のスリット66c内に挿入されて、その先端は抜け穴34gに達している。また、糸通しピン56bの両側面はスリット66cによって挟まれている。   In the needle threading unit 12 configured as described above, when not in use, the cover 32 is in a position (restraint position) that covers most of the needle receiving member 34 as shown in FIGS. The threading member 42 is covered with a cover 32 except for the protruding portions 46g and 48g of the threading main body components 46 and 48. For this reason, the urging force of the spring 58 is sealed in the threading member 42, is restrained at a position close to the needle receiving member 34, and is housed in the cover 32 together with the needle receiving member 34. Therefore, the needle threading unit 12 can be stored compactly in this state. At this time, as shown in FIG. 5, the threading pin 56b of the pin assembly 50 is inserted into the slit 66c of the protective cover 66, and the tip thereof reaches the through hole 34g. Further, both side surfaces of the threading pin 56b are sandwiched between slits 66c.

使用する際には、カバー32を本体30に対して基端側へと摺動させた位置(許容位置)に移動させる。この摺動により、糸通し部材42は、カバー32から脱するので、揺動運動が許容され、バネ58の付勢力によって外方へと揺動する(図6)。このとき、糸通しピン56bは、保護カバー66のスリット66c内にあって保護されている。また、糸通し本体部品46、48の抜け止め突起46f、48fがそれぞれ針受部品36、38の板状部36i、38iに形成された抜け止め突起36p、38pに当接して、糸通し部材42の抜け止めが図られている。   In use, the cover 32 is moved to a position (allowable position) slid toward the base end side with respect to the main body 30. By this sliding, the threading member 42 is detached from the cover 32, and thus swinging motion is allowed, and swings outward by the biasing force of the spring 58 (FIG. 6). At this time, the threading pin 56b is in the slit 66c of the protective cover 66 and is protected. Further, the retaining projections 46f and 48f of the threading main body components 46 and 48 abut on the retaining projections 36p and 38p formed on the plate-like portions 36i and 38i of the needle receiving components 36 and 38, respectively, and the threading member 42 It is designed to prevent slipping out.

次いで、図6及び図7に示すように、針70をその針穴70aの方から針挿入穴34cに挿入する。針70を針挿入穴34cの奥まで挿入すると、マグネット40の磁力によって針70を吸着するので、針70を確実に定位置に固定することができ、針70の落下を防止することができる。   Next, as shown in FIGS. 6 and 7, the needle 70 is inserted into the needle insertion hole 34c from the needle hole 70a. When the needle 70 is inserted all the way into the needle insertion hole 34c, the needle 70 is attracted by the magnetic force of the magnet 40. Therefore, the needle 70 can be securely fixed at a fixed position, and the needle 70 can be prevented from dropping.

また、糸72を糸挿入スリット34eから挿入する。糸挿入スリット34eの末端部は、針穴70aの位置に対応するように設定される。糸挿入スリット34eの末端部は、針挿入穴34cに対して直交する方向に延びているため、この直交する部分まで糸72が到達すればよい。   Further, the thread 72 is inserted from the thread insertion slit 34e. The end of the thread insertion slit 34e is set so as to correspond to the position of the needle hole 70a. Since the end portion of the thread insertion slit 34e extends in a direction orthogonal to the needle insertion hole 34c, the thread 72 only needs to reach the orthogonal portion.

そして、糸通し部材42を押圧して、その糸通し本体部品46、48の突出部46g、48gの先端が針受部材34に接近するように揺動させると、図7及び図8に示すように、糸通しピン部品56の糸通しピン56bの先端は、糸を押し出しながら、針穴70aを通過して、抜け穴34gに達する。糸通し部材42の押圧を解除すると、糸通しピン56bは針穴70aから脱するが、糸72は、針穴70aを通過した状態を維持する。   Then, when the threading member 42 is pressed and swung so that the tips of the projecting portions 46g and 48g of the threading main body components 46 and 48 approach the needle receiving member 34, as shown in FIGS. Furthermore, the tip of the threading pin 56b of the threading pin component 56 passes through the needle hole 70a and reaches the through hole 34g while pushing out the thread. When the pressure of the threading member 42 is released, the threading pin 56b is removed from the needle hole 70a, but the thread 72 is maintained in a state of passing through the needle hole 70a.

この糸通し部材42の揺動時に、糸通しピン56bは、保護カバー66のスリット66c内を通過しており、スリット66cによって糸通しピン56bの両側面の変位が制限されるために、細い糸通しピン56bの折れ・曲がりを防止することができる。保護カバー66は、糸通し部材42の突出部46g、48gが接近すると、変形して、糸通し部材42が針受部材34に接近するのを阻害しないようになっているとよく、糸挿入スリット34eを閉じて、挿入した糸が逃げないようにするとよい。また、別の糸を誤って挿入することもできないようになっているとよい。   When the threading member 42 swings, the threading pin 56b passes through the slit 66c of the protective cover 66, and displacement of both side surfaces of the threading pin 56b is restricted by the slit 66c. It is possible to prevent the through pin 56b from being bent or bent. The protective cover 66 may be deformed when the protruding portions 46g and 48g of the threading member 42 approach each other so as not to prevent the threading member 42 from approaching the needle receiving member 34. 34e may be closed so that the inserted thread does not escape. It is also preferable that another thread cannot be mistakenly inserted.

一方、針穴70aが適切な位置にない場合には、糸通しピン56bの先端が針穴70aを通過することができず、針穴70a以外の針の部分に当接する。この場合、無理に糸通し部材42の押圧を続けると、糸通しピン56bがその押圧に耐えられず曲がって破損するおそれがある。しかしながら、本発明によれば、図9に示すように、糸通しピン56bが糸通し部材42の糸押し本体44に対してバネ60のバネ力に抗して揺動するために、糸通しピン56bに作用する力を緩衝させることができ、糸通しピン56bの破損を防ぐことができる。   On the other hand, when the needle hole 70a is not in an appropriate position, the tip of the threading pin 56b cannot pass through the needle hole 70a, and abuts on the portion of the needle other than the needle hole 70a. In this case, if the pressing of the threading member 42 is forcibly continued, the threading pin 56b may not withstand the pressing and may be bent and damaged. However, according to the present invention, as shown in FIG. 9, the threading pin 56b swings against the spring force of the spring 60 with respect to the thread pushing body 44 of the threading member 42. The force acting on 56b can be buffered, and breakage of the threading pin 56b can be prevented.

そしてバネ60のバネ力によって設定される適度な力で糸通しピン56bが針70を押圧することにより、針穴70aが正しい向きとなるように針70を回転させて矯正させることができ、糸通しピン56bが針穴70aを通過することができるようになる。   Then, when the threading pin 56b presses the needle 70 with an appropriate force set by the spring force of the spring 60, the needle 70 can be rotated and corrected so that the needle hole 70a is in the correct orientation. The through pin 56b can pass through the needle hole 70a.

その他には次の作用が期待できる。即ち、糸通しピン56bは、糸通し本体44に対してピン組立体50の突軸52b、54bが長孔46c、48cを摺動する軌跡に沿って揺動する。このとき、糸通し部材42の揺動中心とピン組立体50の揺動中心とがずれているために、ピン組立体50の突軸52b、54bの長孔46c、48cに対する位置に応じて、糸通し部材42の揺動中心から糸通しピン56bの先端までの距離が変化し、糸通しピン56bの針70に対する相対位置が変化する。このため、針穴70aの位置が正規の位置からずれていても、糸通しピン56bの位置が変化することで、糸通しピン56bが針穴70aを通過することができる可能性が高まり、いずれかのピン組立体50の揺動位置で、糸通しピン56bが針穴70aを通過することができるようになる。または、糸通しピン56bの針70に対する相対位置が変化することで、糸通しピン56bが針70に対して効果的に力を及ぼして針穴70aが正しい向きになるように針70の位置を矯正させることの可能性を高めることができる。   In addition, the following effects can be expected. That is, the threading pin 56b swings along a locus in which the projecting shafts 52b and 54b of the pin assembly 50 slide along the long holes 46c and 48c with respect to the threading main body 44. At this time, since the swing center of the threading member 42 and the swing center of the pin assembly 50 are deviated, depending on the positions of the projecting shafts 52b and 54b of the pin assembly 50 with respect to the long holes 46c and 48c, The distance from the swing center of the threading member 42 to the tip of the threading pin 56b changes, and the relative position of the threading pin 56b with respect to the needle 70 changes. For this reason, even if the position of the needle hole 70a is deviated from the normal position, the possibility that the threading pin 56b can pass through the needle hole 70a is increased by changing the position of the threading pin 56b. At the swinging position of the pin assembly 50, the threading pin 56b can pass through the needle hole 70a. Alternatively, by changing the relative position of the threading pin 56b with respect to the needle 70, the position of the needle 70 is adjusted so that the threading pin 56b effectively exerts a force on the needle 70 so that the needle hole 70a is oriented correctly. The possibility of correcting it can be increased.

そして、針70を針挿入穴34cから取り出すと、糸72の一部が針穴70aを通過した状態で取り出される。針穴70aを通過した糸は図10に示すように、ループ状になっているので、糸72の端部を針穴70aが通過するまで、そのループを大きくしていくと、ループが解除されて、糸72が針穴70aを通過し、針糸通しが完成する。   When the needle 70 is taken out from the needle insertion hole 34c, a part of the thread 72 is taken out in a state of passing through the needle hole 70a. Since the thread that has passed through the needle hole 70a has a loop shape as shown in FIG. 10, if the loop is enlarged until the needle hole 70a passes through the end of the thread 72, the loop is released. Thus, the thread 72 passes through the needle hole 70a, and the needle threading is completed.

使用が終了すれば、糸通し部材42を押圧して、その糸通し本体部品46、48の突出部46g、48gの先端を針受部材34に接近させた後、カバー32で覆って拘束位置に移動させることで、再び装置全体を小型にすることができる。   When the use is finished, the threading member 42 is pressed and the tips of the threading main body parts 46, 48 are brought close to the needle receiving member 34, and then covered with the cover 32 to the restrained position. By moving it, the entire apparatus can be made smaller again.

以上のように本発明によれば、糸通しピン56bの破損を防ぐことができて、糸通し装置10の耐久性を高めることができる。また、糸通しピン部品56がピン組立体50として一体化されて、糸通し本体44内に収まるので、糸通しピン部品56のより一層の保護を図ることができる。   As described above, according to the present invention, the threading pin 56b can be prevented from being damaged, and the durability of the threading device 10 can be improved. Further, since the threading pin component 56 is integrated as the pin assembly 50 and fits in the threading main body 44, the threading pin component 56 can be further protected.

尚、以上の実施形態において複数の部材で構成した部品を単一部材で構成することも可能であり、または単一の部材で構成した部品を複数の部材で構成することも可能である。   In addition, in the above embodiment, a part constituted by a plurality of members can be constituted by a single member, or a part constituted by a single member can be constituted by a plurality of members.
