Description

本発明は、帆立貝などの貝係止具、並びに貝係止具の連続体に関する。 The present invention relates to a shell locking tool such as a scallop and a continuum of shell locking tools.

帆立貝の養殖として耳吊養殖がある。これは海面近くに横向きに張った横ロープに、多数の縦ロープを縦向きに取り付けて吊るとともに、各縦ロープに差し込んだ貝係止具（ピンともいう）を、帆立貝の稚貝の耳の孔に通して吊持し、その成長を図る方法である。 There is ear hanging aquaculture as aquaculture of scallops. This is a horizontal rope stretched horizontally near the surface of the sea, with a large number of vertical ropes attached vertically and hung, and a shell lock (also called a pin) inserted into each vertical rope is attached to the ears of scallop fry. It is a method of hanging it through a hole and aiming for its growth.

一方、近年では、貝係止具単体ごと、人手により縦ロープに差し込み取り付けるのではなく、いわゆるピンセッターと呼ばれる貝係止具の自動取付け装置が開発され、これに呼応して、貝係止具を平行配置して相互に連続させた貝係止具の連続体（ロール状や平板状など）が販売されている。 On the other hand, in recent years, instead of manually inserting and attaching the shell lock to the vertical rope, a so-called pinsetter, which is an automatic attachment device for the shell lock, has been developed. A series of shell-locking tools (roll-shaped, flat plate-shaped, etc.) in which the shells are arranged in parallel and connected to each other are on the market.

貝係止具の連続体としては、例えば特許文献１（特許第４８０２２５２号公報）に示されるように、平行に位置する各基材の両端部に貝止め突起２，２を、基材の中央部の両側にそれぞれロープ止め突起３，３を形成するとともに、各ロープ止め突起３，３の内側（基材の中心側）に連結材１３，１３を位置させ、この連結材により隣接する基材１，１間を連結し、全体としてロール状又は多数個が平板状にひとまとまりになった状態の貝係止具の連続体が知られている。 As a continuum of shell locking tools, for example, as shown in Patent Document 1 (Japanese Patent No. 4802252), shell stopper protrusions 2 and 2 are provided at both ends of each base material located in parallel, and the center of the base material. Rope stopper protrusions 3 and 3 are formed on both sides of the portion, respectively, and connecting members 13 and 13 are positioned inside the rope stopper protrusions 3 and 3 (center side of the base material), and the base materials adjacent to each other by the connecting material. There is known a continuum of shell-locking tools in which 1, 1 are connected and a roll or a large number of pieces are grouped together in a flat plate shape as a whole.

他方で、特許文献１の図１３に貝の吊持状態が示されているように、片側あたり、貝止め突起とロープ止め突起との間に１個の貝のみを吊持する（両側で２個を吊持する）ようにしている。
帆立貝の稚貝の耳の孔に、貝係止具の端を通して、貝を吊すのは手作業で行っている。手作業で数千個の耳通しを行うのは、負担がきわめて大きい。 On the other hand, as shown in FIG. 13 of Patent Document 1, the suspended state of the shell is shown, and only one shell is suspended between the shell stopper protrusion and the rope stopper protrusion on one side (2 on both sides). (Hanging the pieces).
The scallops are manually hung through the ears of the scallop fry through the end of the shell lock. It is extremely burdensome to manually pass through thousands of ears.

特許第４８０２２５２号公報Japanese Patent No. 4802252

しかるに、一つの貝係止具により多くの貝を係止させることができれば、当該貝係止具の交換頻度が少なくなるので、全体として、貝の耳通しの手間が省力化できる。また、材料コストの低減にもつながる。 However, if a large number of shells can be locked by one shell locking tool, the frequency of replacement of the shell locking tool is reduced, so that the labor of passing the shells through the ears can be saved as a whole. It also leads to a reduction in material cost.

しかしながら、現状において、例えば特許文献１の図８の形態のものでは、片側あたり、貝止め突起とロープ止め突起との間に吊持できるのは、通常は、１個の貝のみである。
しからば、単純に、貝止め突起とロープ止め突起との間の長さを長くすればよいとの発想に到るかもしれないが、これでは基材の先端側が過度に垂れ下がる傾向になり、波によって揺動したとき貝相互が衝突を繰り返すことになりかねない。 However, at present, for example, in the form of FIG. 8 of Patent Document 1, only one shell can be suspended between the shell stopper protrusion and the rope stopper protrusion per side.
It may come to the idea that the length between the shell stopper and the rope stopper should be simply increased, but this tends to cause the tip side of the base material to hang excessively. When swaying due to waves, the shells may repeatedly collide with each other.

そこで、本発明の主たる課題は、貝係止具の片側あたり複数個の貝を吊持可能な貝係止具を提供することにある。 Therefore, a main object of the present invention is to provide a shell locker capable of suspending a plurality of shells per side of the shell locker.

上記課題を解決するため本発明の貝係止具は、
基材の両端の対称位置に形成された貝止め突起と、
基材の中央の両側の対称位置にそれぞれ形成された対称形状の第１突起と、
一方の片側の第１突起の外側に近接して形成された第２突起と、
他方の片側の第１突起の外側に近接して形成された第３突起と、を有し、かつこれらの各突起は同一平面上の同一方向側に突出してしており、
前記第１突起と前記第２突起とはそれらの間の前記基材の前記平面上の変形により衝突する近接関係にあり、
前記第３突起と対応する貝止め突起との離間間隔が、前記第２突起と対応する貝止め突起との離間間隔より長い、
ことを特徴とするものである。 In order to solve the above problems, the shell locking tool of the present invention
The shell stopper protrusions formed at symmetrical positions on both ends of the base material,
Symmetrical first protrusions formed at symmetrical positions on both sides of the center of the base material,
A second protrusion formed close to the outside of the first protrusion on one side,
It has a third protrusion formed close to the outside of the first protrusion on the other side, and each of these protrusions protrudes in the same direction on the same plane.
The first protrusion and the second protrusion are in a close relationship between them so as to collide with each other due to the deformation of the base material on the plane.
The distance between the third protrusion and the corresponding shell stopper is longer than the distance between the second protrusion and the corresponding shell stopper.
It is characterized by that.

また、本発明の貝係止具の連続体は、
平行に位置する複数基材の各基材の両端の対称位置に形成された貝止め突起と、
基材の中央の両側の対称位置にそれぞれ形成された対称形状の連結部と、
一方の片側の第１突起の外側に近接して形成された第２突起と、
他方の片側の第１突起の外側に近接して形成された第３突起と、を有し、かつこれらの各突起は同一平面上の同一方向側に延在しており、
前記各基材は前記連結部によって連結されており、
前記連結部が切断され、貝係止具として個別化された状態において、前記連結部と前記第２突起とはそれらの間の前記基材の前記平面上の変形により衝突する近接関係にあり、
前記第３突起と対応する貝止め突起との離間間隔が、前記第２突起と対応する貝止め突起との離間間隔より長い、
ことを特徴とするものである。 Further, the continuum of the shell locking tool of the present invention is
Shell protrusions formed at symmetrical positions at both ends of each base material of multiple base materials located in parallel,
Symmetrical connecting parts formed at symmetrical positions on both sides of the center of the base material,
A second protrusion formed close to the outside of the first protrusion on one side,
It has a third protrusion formed close to the outside of the first protrusion on the other side, and each of these protrusions extends in the same direction on the same plane.
The base materials are connected by the connecting portion, and the base materials are connected by the connecting portion.
In a state where the connecting portion is cut and individualized as a shell locking tool, the connecting portion and the second protrusion are in a close relationship in which they collide with each other due to deformation of the base material on the plane.
The distance between the third protrusion and the corresponding shell stopper is longer than the distance between the second protrusion and the corresponding shell stopper.
It is characterized by that.

本発明は、貝係止具自体（貝係止具単体）と、貝係止具の連続体（例えばロール状に巻いた連続体）に係るものである。
貝係止具の連続体は連結部で切断され、貝係止具単体として個別化されるが、切断された連結部は、貝係止具単体の第１突起として機能させることができる。
この意味で、貝係止具自体（貝係止具単体）と、貝係止具の連続体とは、発明の単一性を定める強い技術的関係を有するものである。 The present invention relates to a shell locker itself (a single shell locker) and a continuum of shell locks (for example, a roll-shaped continuum).
The continuum of the shell locking tool is cut at the connecting portion and individualized as the shell locking tool alone, but the cut connecting portion can function as the first protrusion of the shell locking tool alone.
In this sense, the shell lock itself (single shell lock) and the continuum of the shell lock have a strong technical relationship that determines the unity of invention.

本発明の作用効果について、貝係止具をもって説明すると、次のとおりである。
第３突起と対応する貝止め突起との離間間隔が、第２突起と対応する貝止め突起との離間間隔より長くしてある。これにより、第３突起と貝止め突起との間に、例えば２個の帆立貝を吊り下げることができる。 The action and effect of the present invention will be described below with the shell locking tool.
The distance between the third protrusion and the corresponding shell stopper protrusion is longer than the distance between the second protrusion and the corresponding shell stopper protrusion. Thereby, for example, two scallops can be hung between the third protrusion and the shell stopper protrusion.

かかる態様において、しからば他側の第２突起について不要であるとの考え方もあり得る。しかし、第１突起のみでは、波の影響などで貝係止具が軸方向に動き、第１突起が伏倒して、貝係止具がロープから抜けてしまう可能性がある。
これに対し、他側の第１突起の外側に第２突起が近接して形成されていることにより、貝係止具がロープから抜けてしまうことを抑制できる。
すなわち、第１突起と第２突起とは、それらの間の基材の平面上の変形により衝突する近接関係にあるので、第１突起と第２突起とが衝突して支え合う形態となり、第１突起及び第２突起の変形が抑制でき、もって、貝係止具がロープから抜けてしまうことを抑制できるものである。 In such an embodiment, it may be considered that the second protrusion on the other side is unnecessary. However, with only the first protrusion, the shell locker may move in the axial direction due to the influence of waves, the first protrusion may fall down, and the shell locker may come off the rope.
On the other hand, since the second protrusion is formed close to the outside of the first protrusion on the other side, it is possible to prevent the shell locking tool from coming off the rope.
That is, since the first protrusion and the second protrusion collide with each other due to the deformation of the base material on the plane between them, the first protrusion and the second protrusion collide with each other and support each other. Deformation of the 1st protrusion and the 2nd protrusion can be suppressed, and thus the shell locking tool can be prevented from coming off the rope.

ここで注目すべきは、第３突起の外側に例えば２個、第２突起の外側に１個の貝を吊持する関係で、貝係止具は吊持重量との関係で、主に第３突起側方向に移動しようとする力が支配的となる。
したがって、第２突起側において、第１突起と第２突起とでロープからの抜け止めを図れば、結果として、貝係止具がロープから抜けてしまうことを的確に抑制できるものである。 What should be noted here is that, for example, two shells are suspended on the outside of the third protrusion and one shell is suspended on the outside of the second protrusion. 3 The force that tries to move in the direction of the protrusion becomes dominant.
Therefore, if the first protrusion and the second protrusion are used to prevent the shell from coming off the rope on the second protrusion side, it is possible to accurately prevent the shell locking tool from coming off the rope as a result.

他方で、第３突起を形成しない場合には、第３突起と貝止め突起との間の長さはより長くなる。
しかしながら、貝係止具の連続体を、貝係止具の自動取付け装置（ピンセッター）にセットして順次送りながら切断する際に、一方側のみに第２突起が形成されることになるために、基材の軸方向のバランスが悪くなり、連続体の送りが円滑でなくなるおそれがある。
しかし、本発明においては、第３突起を第１突起の外側に形成してあるので、連続体の送りのバランス不整を防止できる。 On the other hand, when the third protrusion is not formed, the length between the third protrusion and the shell stopper protrusion becomes longer.
However, when the continuous body of the shell locking tool is set in the automatic mounting device (pinsetter) of the shell locking tool and cut while being sequentially fed, the second protrusion is formed only on one side. In addition, the axial balance of the base material may become poor, and the feed of the continuum may not be smooth.
However, in the present invention, since the third protrusion is formed on the outside of the first protrusion, it is possible to prevent imbalance in the feed of the continuum.

本発明の実施の形態として、第３突起の例として後に２つの例を挙げるが、第３突起と対応する貝止め突起との離間間隔が、第２突起と対応する貝止め突起との離間間隔より長い条件の下で、適宜の形状を選択できる。 As an embodiment of the present invention, two examples will be given later as examples of the third protrusion, but the distance between the third protrusion and the corresponding shell stopper protrusion is the distance between the second protrusion and the corresponding shell stopper protrusion. Under longer conditions, the appropriate shape can be selected.

本発明に従えば、最終的には、一つの貝係止具により多くの貝を係止させることができるようにできるので、当該貝係止具の交換頻度が少なくなり、全体として、貝の耳通しの手間が省力化できる。また、材料コストの低減にもつながる。 According to the present invention, it is finally possible to lock a large number of shells with one shell locking tool, so that the frequency of replacement of the shell locking tool is reduced, and as a whole, the shellfish. You can save labor by passing through your ears. It also leads to a reduction in material cost.

本発明によれば、貝係止具の片側あたり複数個の貝を吊持可能な貝係止具を提供することができる。 According to the present invention, it is possible to provide a shell locker capable of suspending a plurality of shells per side of the shell locker.

本発明の実施形態を、図面を参照しながら以下に説明する。 Embodiments of the present invention will be described below with reference to the drawings.

本発明の第１の実施の形態においては、例えば図１〜図３が参照される。
図１は貝係止具の連続体１０の部分を示すもので、図２はその連続部２１Ａ、２１Ｂを、貝係止具の自動取付け装置（ピンセッター。図示せず。）により、例えば切断線Ｘで切断して得た貝係止具１１単体を示している。連続体１０は図１の上下方向のみに連続し、従来のように、ロール状に巻回（ロール状製品は公知であるから、図示を省略してある。）されて商品化される。 In the first embodiment of the present invention, for example, FIGS. 1 to 3 are referred to.
FIG. 1 shows a portion of a continuous body 10 of a shell locking tool, and FIG. 2 shows, for example, cutting the continuous portions 21A and 21B by an automatic mounting device (pinsetter, not shown) of the shell locking tool. The shell locking tool 11 alone obtained by cutting with the wire X is shown. The continuum 10 is continuous only in the vertical direction of FIG. 1, and is wound in a roll shape (the roll-shaped product is known, so the illustration is omitted) as in the conventional case, and the continuum body 10 is commercialized.

先に、図２によって、これ自体でも販売される、貝係止具１１単体を説明することとする。
貝係止具の連続体１０及び貝係止具１１は、たとえばプラスチック樹脂で形成された成形体である。
２〜３ｍｍ程度の細い基材（基材部）１の中央Ｃを対称として、両端部に貝止め突起２、２が形成されている。基材１の中央の両側に対称形状の第１突起２１ａ、２１ｂがそれぞれ形成されている。 First, with reference to FIG. 2, the shell locking tool 11 alone, which is also sold by itself, will be described.
The shell locking tool continuum 10 and the shell locking tool 11 are, for example, molded bodies made of plastic resin.
Shell stopper protrusions 2 and 2 are formed at both ends, with the center C of a thin base material (base material portion) 1 of about 2 to 3 mm as symmetrical. Symmetrical first protrusions 21a and 21b are formed on both sides of the center of the base material 1, respectively.

片側（図面上で右側）の第１突起２１ａの外側に近接して第２突起２２が形成されている。他側（図面上で左側）の第１突起２１ｂの外側に近接して第３突起２３が形成されている。
これらの各突起２、２１ａ、２１ｂ、２２、２３は同一平面上の同一方向側（図面では上方側）に突出してしている。 The second protrusion 22 is formed close to the outside of the first protrusion 21a on one side (on the right side in the drawing). The third protrusion 23 is formed close to the outside of the first protrusion 21b on the other side (left side in the drawing).
Each of these protrusions 2, 21a, 21b, 22, 23 protrudes to the same direction side (upper side in the drawing) on the same plane.

実施の形態では、第１突起２１ａ、２１ｂは、その先端側が基材１と直交する方向に延在し、基部側が基材の中央から離れるように傾斜して基材１に連なっている。 In the embodiment, the first protrusions 21a and 21b extend in a direction orthogonal to the base material 1 on the tip side thereof, and are connected to the base material 1 by being inclined so that the base side is away from the center of the base material 1.

第２突起２２は、その先端側が基材１の中央側に向いて傾斜している。
第２突起２２の先端部と第１突起２１ａとは、それらの間の基材１の平面上の変形により衝突する程度の近接関係にある。 The tip side of the second protrusion 22 is inclined toward the center side of the base material 1.
The tip of the second protrusion 22 and the first protrusion 21a are in a close relationship to the extent that they collide with each other due to deformation of the base material 1 on a plane.

第３突起２３は、第１突起２１ｂの根元に近接して基材１と直交する方向に直線状に突出している。 The third protrusion 23 projects linearly in a direction orthogonal to the base material 1 in the vicinity of the root of the first protrusion 21b.

他方で、図２に示される第１突起２１ａ、２１ｂ相互の離隔長さは、図３に示すように、貝係止具１１の保持用の（縦）ロープＲの直径と同じかやや長いものとされている。 On the other hand, as shown in FIG. 3, the separation length between the first protrusions 21a and 21b shown in FIG. 2 is the same as or slightly longer than the diameter of the (vertical) rope R for holding the shell locking tool 11. It is said that.

従来の貝係止具の一般は中央Ｃを境にして対称であり、２Ｌの長さを有しているが、実施の形態の貝係止具１１は、上記の構成（Ｄ＞Ｅ）の結果、図２に示すように、第３突起２３側（図２の左側）における、第３突起２３と貝止め突起２との離隔距離ＷＢが、他側（図２の右側）の第１突起２１ａと貝止め突起２との離隔距離ＷＡに対して、実質的に第２突起２２の傾斜分と第１突起２１ａとの離間分が関係して（その関係は可能な限り寸法を忠実に図示した寸法関係から明らかであろう。）、長くなる。 The conventional shell locking tool is generally symmetrical with the center C as a boundary and has a length of 2L. However, the shell locking tool 11 of the embodiment has the above configuration (D> E). As a result, as shown in FIG. 2, the separation distance WB between the third protrusion 23 and the shell stopper protrusion 2 on the third protrusion 23 side (left side in FIG. 2) is the first protrusion on the other side (right side in FIG. 2). With respect to the separation distance WA between the 21a and the shell stopper protrusion 2, the inclination of the second protrusion 22 and the distance between the first protrusion 21a are substantially related (the relationship shows the dimensions as faithfully as possible). It will be clear from the dimensional relationship that was made.), It becomes longer.

その結果、図３に示すように、第３突起２３と貝止め突起２との間に、例えば２個の帆立貝Ｓ，Ｓを吊り下げることができる。 As a result, as shown in FIG. 3, for example, two scallops S and S can be hung between the third protrusion 23 and the shell stopper protrusion 2.

貝止め突起の形状については従来から種々の工夫がなされてきた。本発明においても、そのような公知の貝止め突起の形状・形態を使用できる。 Various ideas have been made for the shape of the shell stopper protrusion. Also in the present invention, such a known shape and shape of the shell stopper protrusion can be used.

実施の形態では、第１突起２１ａ、２１ｂの径を同一としてあるが、異ならせてもよい。第２突起２２は、図示のように、傾斜していなくとも、例えば第１突起２１ａに近接した位置から基材１と直交する方向に延在するものでもよい。 In the embodiment, the diameters of the first protrusions 21a and 21b are the same, but they may be different. As shown in the drawing, the second protrusion 22 may extend from a position close to the first protrusion 21a in a direction orthogonal to the base material 1, even if it is not inclined.

第３突起２３の存在は、貝係止具１２の軸方向のバランスを補償し、貝係止具の自動取付け装置（ピンセッター）にセットして順次送りながら切断する際の送りの安定化につながる。
また、第３突起２３は、過度の変形の際に、第１突起２１ｂと支え合い、ロープからの抜け止め機能も期待できる。 The presence of the third protrusion 23 compensates for the axial balance of the shell locker 12, and stabilizes the feed when the shell locker is set in the automatic attachment device (pinsetter) of the shell locker and is sequentially fed while cutting. Connect.
Further, the third protrusion 23 supports each other with the first protrusion 21b when it is excessively deformed, and can be expected to have a function of preventing the rope from coming off.

第３突起の形状は、図示以外の他の形状であってもよい。この例を図４及び図５に示した。
図４は貝係止具の連続体１２の部分を示すもので、図５はその連続部２１０、２１０を、例えば切断線Ｘで切断して得た貝係止具１３単体を示している。 The shape of the third protrusion may be a shape other than that shown in the drawing. An example of this is shown in FIGS. 4 and 5.
FIG. 4 shows a portion of the continuous body 12 of the shell locking tool, and FIG. 5 shows a single shell locking tool 13 obtained by cutting the continuous portions 210 and 210, for example, along the cutting line X.

第３突起２３Ｙは、その基部側２３ｐが基材１と直交する方向に延在し、先端側２１ｑが外方に向き、基材１に近づくように傾斜してている。 The base side 23p of the third protrusion 23Y extends in a direction orthogonal to the base material 1, and the tip side 21q faces outward and is inclined so as to approach the base material 1.

この形態においても、図５の左側においては、第３突起２３Ｙと貝止め突起２との間に、例えば２個の帆立貝Ｓ，Ｓを吊り下げることができるものである。 Also in this form, on the left side of FIG. 5, for example, two scallops S and S can be hung between the third protrusion 23Y and the shell stopper protrusion 2.

本発明は、帆立貝のほか、真珠貝や牡蠣などの貝も対象とすることができる。 The present invention can be applied not only to scallops but also to shellfish such as pearl shells and oysters.
