図１７は、係止ピンを集合して成形した樹脂成形品１１０の従来の一例の正面図で、樹脂成形品１１０はロール状成形品として成形されており、係止ピンの単体を構成する製品部１１１…と、この製品部１１１…の一端部に製品部１１１…と直交する方向に配置された直線帯状の一条のランナ部１１２と、このランナ部１１２と各製品部１１１…とを繋ぐゲート部１１３…とからなり、ゲート部１１３…はランナ部１１２から分岐して設けられており、図では、ランナ部１１２は、製品部１１１…の一端側に一条設けられる。   FIG. 17 is a front view of a conventional example of the resin molded product 110 formed by assembling the locking pins. The resin molded product 110 is formed as a roll-shaped product, and is a product constituting a single locking pin. 111, a straight strip-shaped runner portion 112 arranged at one end of the product portion 111 in a direction orthogonal to the product portion 111, and a gate connecting the runner portion 112 and each product portion 111. The gate portions 113 are branched from the runner portion 112. In the figure, the runner portion 112 is provided on one end of the product portion 111.

図１８は、他の従来例で、製品部１１１…の両端部に直交する方向に直線帯状のランナ部１１２，１１２を設け、製品部１１１…の両端部がランナ部１１２，１１２に連結した二条のランナ部を有するタイプである。   FIG. 18 shows another conventional example in which straight strip-like runner portions 112, 112 are provided in a direction perpendicular to both end portions of the product portions 111, and both end portions of the product portions 111 are connected to the runner portions 112, 112. This type has a runner portion.

図１９は、ランナ部１１２、ゲート部１１３及び製品部１１１が繋がった状態を示す要部の拡大図であり、製品部１１１の軸部１１ａの先部挿入部１１１ｂは先細り形状であり、先部挿入部１１１ｂの軸方向後方には、軸部１１１ａから径方向外方に突出するように係止片１１１ｃが突出し、図では示されていないが、軸部１１１ａの長さ方向中間部にはロープ抜止片が、例えば「ハ」字形に突設されている。
ランナ部１１２と製品部１１１の軸部１１１ａの先部挿入部１１１ｂとの接続部は、原料であるナイロン等の流動性が低いものもあることからゲート部１１３のランナ部１１２側に円柱部１１３ａを設けており、ゲート部１１３をカッター１１５で切断する。
これにより製品部１１１…を樹脂成形品１１０から分離し、個々に切り離された製品部、即ち係止ピン１１４を得る。
これを図２０に示す。 FIG. 19 is an enlarged view of the main part showing a state in which the runner part 112, the gate part 113, and the product part 111 are connected, and the tip insertion part 111b of the shaft part 11a of the product part 111 has a tapered shape. A locking piece 111c protrudes from the shaft portion 111a so as to protrude radially outward from the shaft portion 111b at the rear side in the axial direction of the insertion portion 111b, and is not shown in the drawing, but is attached to the intermediate portion in the longitudinal direction of the shaft portion 111a. The retaining piece protrudes in a “C” shape, for example.
The connecting portion between the runner portion 112 and the tip portion insertion portion 111b of the shaft portion 111a of the product portion 111 has a low fluidity such as nylon as a raw material, so that the cylindrical portion 113a on the runner portion 112 side of the gate portion 113. And the gate portion 113 is cut by a cutter 115.
As a result, the product parts 111 are separated from the resin molded product 110 to obtain individually separated product parts, that is, locking pins 114.
This is shown in FIG.

図２１は、図１９の他の例を示す図である。
この例は、ゲート部１１３が直接ランナ部１１２に接続されている例で、カッター１１５で同様に切断し、図２２に示した係止ピン１１４を得る。
以上で得られる係止ピン１１４は、カッター１１５で切断した先部挿入部１１１ｂの先端部１１１ｄが、図２０、図２２に示すように円柱状で角張った形状となる。 FIG. 21 is a diagram showing another example of FIG.
This example is an example in which the gate portion 113 is directly connected to the runner portion 112 and is similarly cut by the cutter 115 to obtain the locking pin 114 shown in FIG.
The locking pin 114 obtained as described above has a columnar and angular shape as shown in FIGS. 20 and 22 at the tip end portion 111d of the tip insertion portion 111b cut by the cutter 115.

図２３及び図２４は、本考案が解決しようとする課題を示した説明図である。
図２３は、一枚通し耳吊りを示す図で、帆立貝の耳片１１６への係止ピン１１４の刺通係止を示し、帆立貝１１１６の耳片１１６ａにはドリルで係止孔１１６ｂを穿孔し、係止孔１１６ｂに係止ピン１１４の先部挿入部１１１ｂを刺通し、係止ピン先部挿入部に帆立貝耳片を係止保持する。
稚貝の耳片の係止孔は、例えば１．５〜１．９mmであって、極小径である。 23 and 24 are explanatory views showing problems to be solved by the present invention.
FIG. 23 is a diagram showing one-piece hanging, showing the piercing lock of the locking pin 114 to the scallop ear piece 116, and drilling a locking hole 116 b in the ear piece 116 a of the scallop 1116 with a drill. The tip insertion portion 111b of the locking pin 114 is inserted into the locking hole 116b, and the scallop ear piece is locked and held in the locking pin tip insertion portion.
The locking holes of the juvenile ear pieces are, for example, 1.5 to 1.9 mm and have a minimum diameter.

ところで、耳片係止ピン１１４の先端部１１１ｄは、上記したように、円柱状で角張った形状であり、上から先端部１１１ｄを挿入する際、先端部１１１ｄと係止孔１１６ｂとが一致しない場合は、係止係止ピン１１４の先端部１１１ｄの係止孔１１６ｂへの矢印ａ方向からの挿入がスムーズになされず、係止ピン１１４を矢印ｂ，ｃのように揺すったり、曲げ方向に変形させ、先端部１１１ｄを係止孔１１６ｂに無理に挿入し、稚貝への係止ピンの挿入作業の円滑を阻害し、作業効率が低下する。   By the way, as described above, the tip end portion 111d of the ear piece locking pin 114 has a cylindrical and angular shape, and when the tip end portion 111d is inserted from above, the tip end portion 111d and the locking hole 116b do not coincide with each other. In this case, the insertion from the direction of the arrow a into the locking hole 116b of the tip end portion 111d of the locking locking pin 114 is not smoothly performed, and the locking pin 114 is shaken as indicated by arrows b and c, or in the bending direction. The tip end portion 111d is forcibly inserted into the locking hole 116b, the smooth operation of inserting the locking pin into the juvenile shell is hindered, and the working efficiency is lowered.

図２４は、二枚通し耳吊りを示す図で、重ね合わされた二枚の耳片１１６ｃ，１１６ｄにドリルで同心に係止孔１１６ｅ，１１６ｆを二枚通しで穿孔するものであるが、穿孔する際、稚貝の殻が外方に膨出した形状であること、表面に凹凸条を有すること等から、穿孔に際し姿勢が変化し、上下の係止孔１１６ｅ，１１６ｆは上下で位置がズレて不一致となることが多い。
稚貝の耳片の係止孔は、前記したのと同様に１．５〜１．９mmであって、極小径であることもあり、上の係止孔１１６ｅに先端部１１１ｄを挿入し、次に、下の係止孔１１６ｆに先端部１１１ｄを挿入する。 FIG. 24 is a diagram showing two-piece ear suspension, in which two overlapped ear pieces 116c, 116d are drilled concentrically with two pieces of locking holes 116e, 116f. At this time, the posture of the shellfish shells 116e and 116f is shifted up and down due to the shape of the shell of the juvenile shell bulging outward and the surface having irregular stripes. Often disagreement.
The locking hole of the juvenile ear piece is 1.5 to 1.9 mm, as described above, and may have a very small diameter. The tip 111d is inserted into the upper locking hole 116e, Next, the tip 111d is inserted into the lower locking hole 116f.

この下側の掛止孔１１６ｆへの矢印ａのように上からの挿入に際し、上側の係止孔１１６ｅの位置と下側の係止孔１１６ｆの位置が一致しないため、角張った先端部１１１ｄが係止孔１１６ｆの周辺部に当接し、孔周辺部に当たって挿入することができない。
このため、先部挿入部１１１ｂを含んで係止ピン１１１４を矢印ｂ，ｃのように揺すったり、曲げ方向に変形させ、先端部１１１ｄを無理に係止孔１１６ｆに挿入している。
このため、稚貝への係止ピンの挿入作業の円滑を阻害し、作業効率が低下する。 At the time of insertion from above as shown by the arrow a in the lower latching hole 116f, the position of the upper locking hole 116e and the position of the lower locking hole 116f do not coincide with each other. It abuts on the periphery of the locking hole 116f and cannot be inserted by hitting the periphery of the hole.
For this reason, the locking pin 1114 including the tip insertion portion 111b is shaken as indicated by arrows b and c, or deformed in the bending direction, and the tip 111d is forcibly inserted into the locking hole 116f.
For this reason, smooth operation of inserting the locking pin into the juvenile is hindered, and work efficiency is reduced.

また、帆立貝の養殖は、図１５、図１６で説明したように、係止ピンをロープの長さ方向に直交する方向に貫通・保持させ、前記したように、係止ピンの両端部に稚貝の耳片を貫通させ、海中に縦向きにロープを吊り下げてなされるものであり、１本のロープに１００本以上の係止ピンを係止し、各係止ピンの先端部に稚貝を係止する。
ところで、ロープ１００に穿孔された保持孔１００ａは、捩った繊維体に穿孔することから内周面に絡んだ繊維材が露出していたりして、係止ピン１１４の先端部１１１ｄが引っ掛かり、ロープの保持孔１００ａへの係止ピン１１４の円滑な挿入が阻害され、上記と同様の不都合が生じている。
これを図２５に示す。
図２６は、ランナ部１１２と係止ピン製品部１１１との間のゲート部が丸棒状であり、ゲート部を切断した状態で図２７に示すように係止ピン１１４の先端部１１ｄの先に丸棒状の残留部１１２ａが残り、残留部１１２ａの先端面１１２ｂは角張った形状をなし、図２８に示すように係止ピン１１４を帆立貝１１６の耳片１１６ａの係止孔１１６ｂに挿入する際、先端面１１２ｂが孔周辺部の当たり、前記と同様の不具合がある。 As shown in FIGS. 15 and 16, the scallops are cultivated by penetrating and holding the locking pins in a direction perpendicular to the length direction of the rope, and as described above, at both ends of the locking pins. It is made by penetrating the ears of shellfish and suspending a rope vertically in the sea. More than 100 locking pins are locked to one rope, and the tip of each locking pin is Lock the shellfish.
By the way, since the holding hole 100a drilled in the rope 100 is drilled in the twisted fiber body, the fiber material entangled with the inner peripheral surface is exposed, and the tip end portion 111d of the locking pin 114 is caught, Smooth insertion of the locking pin 114 into the rope holding hole 100a is hindered, resulting in the same inconvenience as described above.
This is shown in FIG.
In FIG. 26, the gate portion between the runner portion 112 and the locking pin product portion 111 has a round bar shape, and the gate portion is cut off at the tip of the distal end portion 11d of the locking pin 114 as shown in FIG. A round bar-like residual portion 112a remains, and the distal end surface 112b of the residual portion 112a has an angular shape. When the locking pin 114 is inserted into the locking hole 116b of the ear piece 116a of the scallop 116, as shown in FIG. There is a problem similar to the above when the tip surface 112b hits the hole periphery.

It is possible to smoothly and easily insert the tip insertion portion of the stop pin, and it is possible to achieve smooth, easy and efficient mounting of the locking pin in the scallop culture work.
Further, when the tip insertion portion of the locking pin is inserted into the holding hole of the rope, the insertion can be performed smoothly and easily in the same manner.
Accordingly, it is possible to achieve smooth, easy and efficient attachment work of the locking pin to the scallop in the scallop culturing work, and smooth, easy and efficient work of inserting and holding the locking pin to the rope.

請求項２に係る考案では、係止ピンを得る樹脂成形品であって、ランナ部と、このランナ部から分岐した分岐部と、この分岐部の先に設けられたゲート部と、このゲート部の先に設けられた製品部とからなり、分岐部は先端が半円球状であり、製品部は、軸部と、軸部の一端部に帆立貝の係止孔に挿入する先部挿入部を有し、この先部挿入部の軸方向内方部位に径方向外方に突出し、先部挿入部とは反対方向に傾斜した係止片を有し、先部挿入部は円半球状であり、分岐部の半円球状先端部と、これと向かい合う軸部の半円球状先部挿入部との間を繋ぐゲート部は、半円球状分岐部、半円球状先端部よりも小径で、且つ長さが０．１mm〜０．４mmとした。
従って、ランナ部と係止ピンとなる製品部とを繋ぐゲート部は、ランナ側の半円球状分岐部、製品部（係止ピン側）の半円球状先端部よりも小径で、且つ長さが０．１mm〜０．４mmなので、ゲート部を切断した際、或いは折り曲げ加工で切り離した際、ランナ部の残留部は極小となり、係止ピン側の先部挿入部の半円球状先端部は小平頭状となる。
従って、帆立貝の係止孔に係止ピンの先部挿入部を挿入する際に、小さな平頭部周辺の円球状体端面が係止孔縁辺部に接して抵抗少なく、円滑に、また、調心作用的に係止孔に侵入し、帆立貝係止孔への係止ピンの先部挿入部の挿入を円滑、容易化に行うことができ、帆立貝養殖作業における係止ピンの装着作業の円滑、容易化、効率化を図ることができる係止ピンを得ることが可能となる。 The invention according to claim 2 is a resin molded product for obtaining a locking pin, a runner portion, a branch portion branched from the runner portion, a gate portion provided at the end of the branch portion, and the gate portion. The product part is provided with a tip of the bifurcated part, the tip of the branch part is hemispherical, and the product part is provided with a shaft part and a tip part insertion part to be inserted into the locking hole of the scallop at one end of the shaft part And having a locking piece that protrudes radially outward in the axially inner portion of the tip insertion portion and that is inclined in a direction opposite to the tip insertion portion, the tip insertion portion is a hemispherical shape, The gate part connecting the semispherical tip of the branch part and the semispherical tip insertion part of the shaft part facing this is smaller in diameter and longer than the semispherical branch part and the semispherical tip part. The thickness was set to 0.1 mm to 0.4 mm.
Therefore, the gate part that connects the runner part and the product part serving as the locking pin is smaller in diameter and longer than the hemispherical branch part on the runner side and the semispherical tip part on the product part (locking pin side). Since it is 0.1 mm to 0.4 mm, when the gate part is cut or separated by bending, the remaining part of the runner part is minimized, and the semicircular tip of the tip insertion part on the locking pin side is small. It becomes flat-headed.
Therefore, when the tip insertion portion of the locking pin is inserted into the locking hole of the scallop, the end face of the spherical body around the small flat head is in contact with the edge of the locking hole, and the resistance is reduced smoothly. It is possible to smoothly enter the locking hole and insert the insertion portion of the locking pin into the scallop locking hole smoothly and easily. Thus, it is possible to obtain a locking pin that can be made easier and more efficient.

請求項３に係る考案では、係止ピンを得る樹脂成形品であって、ランナ部と、このランナ部から分岐した分岐部と、この分岐部の先に設けられたゲート部と、このゲート部の先に設けられて製品部とからなり、ランナ部の製品部に向かい合う面は直線状であり、製品部は、ランナ部と直交するように設けられた軸部と、軸部の一端部に帆立貝の係止孔に挿入する先部挿入部を有し、この先部挿入部の軸方向内方部位に径方向外方に突出し、先部挿入部とは反対方向に傾斜した係止片を有し、先部挿入部は半円球状であり、製品部の軸部先部の半円球状先端部は、ランナ部の製品部に向かい合う面と重複させてゲート部とし、ゲート部の長さは、半円球状先端部の半円球の軸方向長さ１／３〜１／２とした。
従って、係止ピンとなる製品部の軸部先部の半円球状先端部を、ランナ部の製品部に向かい合う面と重複させてゲート部とし、重複したゲート部の長さが半円球状先端部の半円球の軸方向長さ１／３〜１／２なので、ゲート部を切断した際、ランナ部の残留部は発生せず、切り離した係止ピン側の先部挿入部の半円球状先端部は小平頭状となる。
従って、帆立貝の係止孔に係止ピンの先部挿入部を挿入する際に、小さな平頭部周辺の円球状体端面が係止孔縁辺部に接して抵抗少なく、円滑に、また、調心作用的に係止孔に侵入し、帆立貝係止孔への係止ピンの先部挿入部の挿入を円滑、容易化に行うことができ、帆立貝養殖作業における係止ピンの装着作業の円滑、容易化、効率化を図ることができる係止ピンを得ることが可能となる。 The invention according to claim 3 is a resin molded product for obtaining a locking pin, a runner portion, a branch portion branched from the runner portion, a gate portion provided at the end of the branch portion, and the gate portion. The surface of the runner part facing the product part is straight, and the product part is provided at the shaft part provided perpendicular to the runner part and at one end of the shaft part. It has a tip insertion portion that is inserted into the locking hole of the scallop, and has a locking piece that protrudes radially outward at an axially inner portion of the tip insertion portion and is inclined in the direction opposite to the tip insertion portion.

Therefore, the semi-spherical tip of the shaft tip of the product part that becomes the locking pin is overlapped with the surface of the runner part facing the product part to form a gate part, and the length of the overlapping gate part is a semi-spherical tip part. Since the axial length of the semicircular sphere is 1/3 to 1/2, when the gate portion is cut, the runner remaining portion does not occur, and the semicircular sphere of the tip insertion portion on the side of the separated locking pin The tip has a small flat head shape.
Therefore, when the tip insertion portion of the locking pin is inserted into the locking hole of the scallop, the end face of the spherical body around the small flat head is in contact with the edge of the locking hole, and the resistance is reduced smoothly. It is possible to smoothly enter the locking hole and insert the insertion portion of the locking pin into the scallop locking hole smoothly and easily. Thus, it is possible to obtain a locking pin that can be made easier and more efficient.

本考案の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１は、係止ピンを作る樹脂成形品の要部の拡大図、図２は、図１の要部の断面図で、カッターで切断する説明図である。
図１は、樹脂成形品１の要部の拡大図における一方のランナ部２、これに直交するように設けられた製品部３を示し、全体としては、図１７、図１８と同様に製品部３は図の上下に多数所定ピッチで併設されている。
尚、樹脂成形品１の素材であるが、係止ピンとして用いた場合、帆立貝を係止して海中に侵浸した際、海中で水分を吸収し、これにより少し柔らかくなり、また、伸ばすと約３倍程度延伸するので、例えば、６６ナイロン等を用いる。 Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
FIG. 1 is an enlarged view of a main part of a resin molded product for making a locking pin, and FIG. 2 is a cross-sectional view of the main part of FIG.
FIG. 1 shows one runner portion 2 in an enlarged view of a main part of a resin molded product 1 and a product portion 3 provided so as to be orthogonal to the runner portion 2. As a whole, the product portion is similar to FIGS. 17 and 18. A number 3 is provided at a predetermined pitch on the top and bottom of the figure.
Although it is a material of the resin molded product 1, when it is used as a locking pin, when the scallop is locked and infiltrated into the sea, it absorbs moisture in the sea, which makes it slightly softer and stretched. For example, 66 nylon is used because it stretches about 3 times.

前記した製品部３の軸部３ａの先部３ｂは、先端部３ｃが半円球状である。
一方、ランナ部２の内側面には、製品部３の半円球状の先端部３ｃと向かい合うように、円柱状の分岐基部２ａを内側方に突設されており、分岐基部２ａの先部には、先端部２ｃが半円球状の分岐部２ｂが形成されている。
このランナ部２の分岐部２ｂの半円球状先端部２ｃと、これに向かい合う製品部３の半円球状の先端部３ｃとの間の中央部には、これら半円球状体の中央部間を、ゲート部４で繋いでいる。 The tip portion 3b of the shaft portion 3a of the product portion 3 described above has a semicircular spherical tip portion 3c.
On the other hand, on the inner side surface of the runner part 2, a cylindrical branch base 2a is projected inward so as to face the hemispherical tip 3c of the product part 3, and is provided at the front of the branch base 2a. The tip 2c is formed with a semicircular branch 2b.
The central part between the semispherical tip 2c of the branch part 2b of the runner part 2 and the semicircular tip 3c of the product part 3 facing the branch part 2b is located between the central parts of these semispherical bodies. , Connected by the gate part 4.

前記したゲート部４は、半円球状の製品部３の先端部３ｃの径、ランナ部２の分岐部２ｂの半円球状先端部２ｃの径よりも十分に小径である。
また、ゲート部４の長さ、つまりは、半円球状の製品部３の先端部３ｃと、ランナ部２の分岐部２ｂの半円球状先端部２ｃとの間の間隔は、０．１mm〜０．４mmとする。
図では、先端部３ｃと半円球状先端部２ｃとの間の間隔を理解の便のため大きく表している。 The gate part 4 described above has a diameter sufficiently smaller than the diameter of the tip part 3c of the semispherical product part 3 and the diameter of the semispherical tip part 2c of the branch part 2b of the runner part 2.
Further, the length of the gate portion 4, that is, the distance between the tip portion 3c of the semispherical product portion 3 and the semispherical tip portion 2c of the branch portion 2b of the runner portion 2 is 0.1 mm to 0.4 mm.
In the drawing, the distance between the tip 3c and the semispherical tip 2c is shown greatly for the sake of understanding.

以上のゲート部４は極めて薄いカッター５で図２に示すように切断し、切り離し、図３に示すように係止ピン１０を得る。
尚、カッターによる切断に代え、折り曲げ加工により容易に切り離すことができる。
その理由は、ゲート部は長さが０．１mm〜０．４mm程度の極めて幅狭であり、且つ、小径なので、折り曲げ加工により容易に切り離すことができるのである。 The gate part 4 is cut by a very thin cutter 5 as shown in FIG. 2 and separated to obtain a locking pin 10 as shown in FIG.
In addition, it can replace | disconnect easily by a bending process instead of the cutting | disconnection by a cutter.
The reason is that the gate part is extremely narrow with a length of about 0.1 mm to 0.4 mm and has a small diameter, so that it can be easily separated by bending.

図３は、樹脂成形品１から切り離した係止ピン１０を示し、図４は、先端部の拡大図、図５は、斜視図、図６は係止ピン全体の図、図７は、帆立貝の係止孔に係止ピンの先端部を挿入する説明図である。   3 shows the locking pin 10 separated from the resin molded product 1, FIG. 4 is an enlarged view of the tip, FIG. 5 is a perspective view, FIG. 6 is an overall view of the locking pin, and FIG. 7 is a scallop. It is explanatory drawing which inserts the front-end | tip part of a locking pin in this locking hole.

樹脂成形品１から切り離した係止ピン１０は、軸部１１の先部に先部挿入部１２を備え、先部挿入部１２の軸方向後部には、径方向外方に突出する係止片１４を備える。
先部挿入部１２の先端部１３は半円球状であり、その先端部１３は、図４に示すように先端部の半円球部の先端部を裁頭した平頭部１３ａが形成されており、鎖線で示した半円弧１３ｂを裁断した状態である。 The locking pin 10 separated from the resin molded product 1 includes a tip insertion portion 12 at the tip of the shaft portion 11, and a locking piece that protrudes radially outward at the axial rear portion of the tip insertion portion 12. 14.
The distal end portion 13 of the tip insertion portion 12 is semispherical, and the distal end portion 13 is formed with a flat head portion 13a that is truncated at the distal end portion of the semispherical portion of the distal end portion as shown in FIG. In this state, the semicircular arc 13b indicated by the chain line is cut.

ところで、上記したカッター５による切断による切断痕、或いは、折り曲げ加工の切り離しによる切り離し痕が平頭部に確認されるが、これらの切断痕、切り離し痕は半円球状体の先端部の中央部の一部に認められ、図５に示したように、全体としては略半円球状体である。
従って、全体として先部挿入部１２の先端部１３は概ね半球状体をなし、最先端部のみが極小の平頭部となる。 By the way, although the cutting trace by cutting with the cutter 5 described above or the cutting trace by cutting off the bending process is confirmed on the flat head, these cutting trace and the cutting trace are in the central portion of the tip of the semispherical body. As partly recognized and shown in FIG. 5, the whole is a substantially semispherical body.
Therefore, as a whole, the distal end portion 13 of the tip insertion portion 12 is substantially hemispherical, and only the most distal end portion is a minimal flat head.

図６は、係止ピン１０の全体を示す図で、図では、帆立貝を両端部で吊り下げ係止する両持ち式の係止ピンを示している。
軸部１１の両端には前記した先部挿入部１２，１２を備え、先部挿入部１２，１２の最先端部には平頭部１３ａを有する半円球状先端部１３，１３を有し、先部挿入部１２，１２の軸方向内方には帆立貝係止孔からの抜け止め機能を果たす抜止片１４，１４が径方向外方に突出しており、軸部１１の中間部には「ハ」形にロープ抜止片１５，１５が向かい合うように突設されている。 FIG. 6 is a diagram showing the entire locking pin 10, and in the figure, a double-sided locking pin that suspends and locks the scallop shell at both ends is shown.
The shaft portion 11 includes the tip insertion portions 12 and 12 at both ends, and the tip insertion portions 12 and 12 have semispherical tip portions 13 and 13 having a flat head portion 13a at the most distal end portion. On the inner side in the axial direction of the tip insertion portions 12 and 12, retaining pieces 14 and 14 that serve to prevent the scallop locking holes from protruding are projected outward in the radial direction. The rope retaining pieces 15 and 15 are projected so as to face each other.

以上、図６では帆立貝両持ち式の係止ピンを示したが、一端部にのみ先部挿入部及び抜止片を設けた片持ち式においても、同様であり、一端部の先部挿入部に代えて端部に太径等のロープ抜止部を設けた構造でも良い。   6 shows the scallop shell-type locking pin, the same applies to the cantilever type in which the tip insertion portion and the retaining piece are provided only at one end, Instead, a structure in which a rope retaining portion having a large diameter or the like is provided at the end portion may be used.

図７は、帆立貝５０の耳片５１に穿孔した係止孔５２に係止ピン１０の先部挿入部１２を挿入する状態の説明図であり、図では一枚通しを示す図である。
係止ピン１０の先部挿入部１２の先端部１３は最先端の極小の平頭部１３ａを除いて半円球状であり、平頭部１３ａの周辺部は円球状なので、係止孔５２に先端部１３が侵入する際、球面に倣って調心的に係止孔５２内に侵入し、容易に、且つ円滑に係止孔５２に挿入することができる。
万一、平頭部１３ａが係止孔５２の周辺部に当たったとしても、平頭部１３ａが極小であることから、軸部１１を押すことで平頭部周辺の球面に倣って係止孔５２内に調心的に侵入し、円滑、容易に係止孔５２に係止ピン１０の先部挿入部１２を係止孔５２に挿入することができる。 FIG. 7 is an explanatory view of a state in which the tip insertion portion 12 of the locking pin 10 is inserted into the locking hole 52 drilled in the ear piece 51 of the scallop 50, and is a diagram showing a single piece in the drawing.
The distal end portion 13 of the tip insertion portion 12 of the locking pin 10 is semi-spherical except for the extremely small flat head portion 13a, and the peripheral portion of the flat head portion 13a is spherical. When the tip portion 13 enters, it can enter the locking hole 52 in a centering manner following the spherical surface, and can be easily and smoothly inserted into the locking hole 52.
Even if the flat head 13a hits the peripheral portion of the locking hole 52, the flat head 13a is extremely small. The tip insertion portion 12 of the locking pin 10 can be inserted into the locking hole 52 smoothly and easily.

図８は、帆立貝の係止孔に係止ピンの先端部を挿入する説明図であり、二枚通しの例を示す図で、挿入直前の図であり、図９は、図８の状態から挿入のため係止孔に侵入した状態を示す図である。
前記したように、二枚通し耳吊りでは、重ね合わされた二枚の耳片５３，５４にドリルで同心に係止孔５５，５６を二枚通しで穿孔する際、稚貝の殻が外方に膨出した形状であることや、表面に凹凸条を有すること等から、穿孔に際して姿勢が変化し、上下の係止孔５５，５６は上下で位置がズレて不一致となることが多い。 FIG. 8 is an explanatory view of inserting the tip end portion of the locking pin into the locking hole of the scallop, showing an example of two sheets passing through, just before insertion, and FIG. 9 from the state of FIG. It is a figure which shows the state which penetrate | invaded the latching hole for insertion.
As described above, in the two-piece ear suspension, when the two concavity holes 53 and 54 are drilled concentrically with the two ear pieces 53 and 54 that are overlapped, the shell of the juvenile shell is outward. The shape of the upper and lower locking holes 55 and 56 often shifts and does not coincide with each other due to the bulging shape and the surface having irregular stripes.

しかしながら、本考案に係る係止ピン１０では、係止ピン１０の先部挿入部１２の先端部１３は、最先端の極小の平頭部１３ａを除いて半円球状であり、平頭部１３ａの周辺部は円球状なので、上の係止孔５５から押し込んで挿入するだけで、調心的に中央に寄り、また、下の係止孔５６が位置ズレであっても、平頭部１３ａ周辺部の半円球状部が係止孔５６周縁部に接しつつ調心的に中央に寄り、矢印のように上から挿入するだけで、自動調心的に上下の係止孔５５，５６に通すことができる。
この状態を図９で示した。 However, in the locking pin 10 according to the present invention, the distal end portion 13 of the tip insertion portion 12 of the locking pin 10 has a semi-spherical shape except for the most advanced flat head 13a, and the flat head 13a. Since the peripheral portion of the flat head 13a is inserted into the upper locking hole 55 by simply being pushed in, the flat head 13a is aligned even if it is centered and the lower locking hole 56 is misaligned. The semicircular spherical portion of the peripheral portion is aligned to the center while touching the peripheral edge of the locking hole 56, and it is automatically aligned to the upper and lower locking holes 55, 56 just by inserting from above as indicated by arrows. Can pass through.
This state is shown in FIG.

図１０は、係止ピンを作る他の実施例に係る樹脂成形品の要部の拡大図、図１１は、図１０の要部の断面図で、カッターで切断する説明図である。
図１０は、樹脂成形品２１の要部の拡大図における一方のランナ部２２、これに直交するように設けられた製品部２３を示し、全体としては、上記図１の実施例と同様に製品部２３は図の上下に多数所定ピッチで併設されている。
前記ランナ部２２の製品部２３に向かい合う面２２ａは直線状であり、製品部２３の軸部２３ａの先部２３ｂは、先端部２３ｃが半円球状である。 FIG. 10 is an enlarged view of a main part of a resin molded product according to another embodiment for producing a locking pin, and FIG. 11 is a cross-sectional view of the main part of FIG. 10 and is an explanatory view cut by a cutter.
FIG. 10 shows one runner portion 22 in the enlarged view of the main part of the resin molded product 21 and a product portion 23 provided so as to be orthogonal to the runner portion 22, and the product as a whole is similar to the embodiment of FIG. A large number of portions 23 are provided at a predetermined pitch on the top and bottom of the drawing.
The surface 22a of the runner portion 22 facing the product portion 23 is linear, and the tip portion 23b of the shaft portion 23a of the product portion 23 is semispherical.

以上の製品部２３の軸部２３ａの先部２３ｂの半円球状先端部２３ｃは、ランナ部２２の製品部２３に向かい合う面２２ａと重複させてゲート部２４とする。
このゲート部２４は、ランナ部２２の製品部２３に向かい合う面２２ａの端面と、製品部２３の半円球状先端部２３ｃの最先端部とを繋げる部分で、ゲート部２４の長さは、半円球状先端部の半円球の軸方向長さ１／３〜１／２とする。
ランナ部２２と製品部２３の最先端部２３ｃとの間に形成されるゲート部２４を含む構造を図１１で断面として示した。 The semicircular tip portion 23c of the tip portion 23b of the shaft portion 23a of the product portion 23 described above overlaps with the surface 22a facing the product portion 23 of the runner portion 22 to form a gate portion 24.
The gate portion 24 is a portion that connects the end face of the surface 22a facing the product portion 23 of the runner portion 22 and the most distal end portion of the semicircular tip portion 23c of the product portion 23. The length of the gate portion 24 is half The axial length of the hemisphere at the tip of the sphere is 1/3 to 1/2.
A structure including the gate portion 24 formed between the runner portion 22 and the most distal portion 23c of the product portion 23 is shown as a cross section in FIG.

以上において、図１１に示すようにランナ部２２の向かい合う面２２ａと製品部２３の最先端部である球状先端部２３ｃの境界部をカッター２５で切断し、図１２及び図１３に示した係止ピン３０を得るものである。
樹脂成形品２１から切り離した係止ピン３０は、軸部３１の先部に先部挿入部３２を備え、先部挿入部３２の軸方向後部には、径方向外方に突出する係止片３４を備える。 In the above, as shown in FIG. 11, the boundary portion between the face 22a facing the runner portion 22 and the spherical tip 23c, which is the most distal portion of the product portion 23, is cut by the cutter 25, and the locking shown in FIGS. The pin 30 is obtained.
The locking pin 30 separated from the resin molded product 21 includes a tip insertion portion 32 at the tip of the shaft portion 31, and a locking piece that protrudes radially outward at the axial rear portion of the tip insertion portion 32. 34 is provided.

以上の先部挿入部３２の先端部３３は半円球状であり、その先端部３３は、先端部の半円球部３３の先端部を裁頭した平頭部３３ａが形成されており、先端部３３は、半円球部分の円弧が軸先に対して直角に裁断された状態であり、半円球状先端部３３は、円弧の弧状先端から軸方向長さが１／３〜１／２欠けた状態である。
従って、全体として先部挿入部３２の先端部３３は概ね半球状体をなし、最先端部のみが極小の平頭部となる。 The distal end portion 33 of the tip insertion portion 32 is semispherical, and the distal end portion 33 is formed with a flat head 33a that is truncated from the distal end portion of the semispherical portion 33 of the distal end portion. The portion 33 is a state in which the arc of the semispherical portion is cut at a right angle to the shaft tip, and the semicircular tip 33 has an axial length of 1/3 to 1/2 from the arcuate tip of the arc. It is a lacking state.
Accordingly, as a whole, the distal end portion 33 of the tip insertion portion 32 has a substantially hemispherical shape, and only the most distal portion has a minimal flat head.

図１４は、帆立貝５０の耳片５１に穿孔した係止孔５２に係止ピン３０の先部挿入部３２を挿入する状態の説明図であり、図では一枚通しを示す図である。
係止ピン３０の先部挿入部３２の先端部３３は最先端の極小の平頭部３３ａを除いて半円球状であり、平頭部３３ａの周辺部は円球状なので、係止孔５２に先端部３３が侵入する際、球面に倣って調心的に係止孔５２内に侵入し、容易に、且つ円滑に係止孔５２に挿入することができる。 FIG. 14 is an explanatory diagram of a state in which the tip insertion portion 32 of the locking pin 30 is inserted into the locking hole 52 drilled in the ear piece 51 of the scallop 50, and is a diagram showing a single sheet in the drawing.
The distal end portion 33 of the tip insertion portion 32 of the locking pin 30 is semi-spherical except for the extremely small flat head portion 33a, and the peripheral portion of the flat head portion 33a is spherical. When the distal end portion 33 enters, the tip portion 33 can intrude into the locking hole 52 along the spherical surface and can be inserted into the locking hole 52 easily and smoothly.

万一、平頭部３３ａが係止孔５２の周辺部に当たったとしても、平頭部３３ａが極小であることから、軸部３１を押すことで平頭部周辺の球面に倣って係止孔５２内に調心的に侵入し、円滑、容易に係止孔５２に係止ピン３０の先部挿入部３２を係止孔５２に挿入することができる。
上記と同様にカッター２５による切断等による切断痕等が平頭部に確認されるが、これらの切断痕等は半円球状体の先端部の中央部の一部に認められが、全体としては略半円球状体である。
尚、二枚通しにおいても、上記図８、図９で説明したのと同様である。 Even if the flat head 33a hits the peripheral portion of the locking hole 52, the flat head 33a is extremely small. The tip 52 of the locking pin 30 can be inserted into the locking hole 52 smoothly and easily.
Similar to the above, cutting marks or the like due to cutting by the cutter 25 are confirmed on the flat head, but these cutting marks and the like are recognized in a part of the central part of the tip of the semispherical body, It is a substantially semispherical body.
The two sheets are the same as described with reference to FIGS.
