Description

本発明は、シャックル等の連結具に関するものである。 The present invention relates to a connecting tool such as a shackle.

ロープやワイヤ等の被連結体を連結する連結具であるシャックルとして、略Ｕ字状の金具本体の対向端部に夫々設けた取付孔部の少なくとも一方に螺子孔を設け、この取付孔部に連結ピンを挿通すると共に螺着することで、前記取付孔部間に前記連結ピンを着脱自在に架設して開閉部を構成したものがある。 As a shackle which is a connecting tool for connecting to-be-connected bodies such as a rope and a wire, a screw hole is provided in at least one of the mounting hole portions provided at the opposite end portions of the substantially U-shaped metal fitting body, and the mounting hole portion There is a configuration in which an opening / closing portion is configured by inserting a connecting pin and screwing it so that the connecting pin is detachably installed between the mounting hole portions.

この略Ｕ字状の金具本体の湾曲部においては、底部に被連結体を位置決めすることができ、且つ、この湾曲形状により前記被連結体からの応力が分散し、この湾曲部の各部にかかる応力を小さくできるため、非常に良好な耐久性を発揮できる。 In the curved portion of the substantially U-shaped metal fitting body, the connected body can be positioned at the bottom, and the stress from the connected body is dispersed by the curved shape and is applied to each part of the curved portion. Since the stress can be reduced, very good durability can be exhibited.

しかしながら、開閉部とする必要がある前記湾曲部と対向する連結ピンは直線形状とせざるを得ず、前述の湾曲部において発揮されるような位置決め作用及び応力分散作用が発揮されない。 However, the connecting pin that faces the bending portion that needs to be an opening / closing portion must be linear, and the positioning action and stress distribution action that are exhibited in the bending portion described above cannot be exhibited.

従って、被連結体はこの被連結体に作用する力に応じて容易に連結ピン上を移動してしまい安定的に連結しておくことができず、しかも、被連結体と当接する一部に応力集中が生じて変形しやすいという問題がある。 Therefore, the coupled body easily moves on the coupling pin in accordance with the force acting on the coupled body and cannot be stably coupled, and the coupled body is partly in contact with the coupled body. There is a problem that stress concentration occurs and it is easily deformed.

そこで、この連結ピンに、前記湾曲部と対向して同様な湾曲部を形成し得る湾曲形状に設定されたカバー体を被嵌することで、前記湾曲部と同様に連結ピンにおいても位置決め作用及び応力分散作用を発揮させるように構成したものが提案されている。 Therefore, by fitting a cover body set in a curved shape that can form a similar curved portion facing the curved portion on the coupling pin, the positioning operation and the coupling pin can be performed similarly to the curved portion. The one configured to exhibit the stress dispersion action has been proposed.

ところが、上述のカバー体と前記金具本体とは一体でないため、カバー体が被連結体からの応力により連結ピンを軸として空回りし、場合によってはこの空回りに伴い連結ピンの螺子部と螺子孔の螺着が緩み、最悪連結ピンが取付孔部から脱落してしまうという問題があったのが現状である。 However, since the above-described cover body and the metal fitting body are not integrated, the cover body idles around the connection pin due to the stress from the connected body, and in some cases, the screw portion of the connection pin and the screw hole of the connection pin are accompanied by this idle rotation. At present, there is a problem that the screw connection is loosened and the worst connection pin falls off from the mounting hole.

本発明は、上述のような現状に鑑み、確実に連結ピンを抜け止めし得る構成を簡易な改良で実現したもので、コスト安に長期間安定して被連結体を連結し得る強度及び耐久性に秀れた極めて実用的な連結具を提供するものである。 In view of the present situation as described above, the present invention realizes a structure that can reliably prevent the connecting pin from coming off with a simple improvement, and can provide a strength and durability that can stably connect the connected body for a long time at a low cost. It provides an extremely practical connector with excellent properties.

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。 Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

複数の被連結体９を（開閉部を通じて）金具本体１と、連結ピン４に螺着被嵌したカバー体６とに夫々当接させることで連結する。 The plurality of connected bodies 9 are connected by bringing them into contact with the metal fitting main body 1 (through the opening / closing portion) and the cover body 6 screwed onto the connecting pin 4.

この被連結体９からカバー体６に、このカバー体６を回転させる力が作用した際、カバー体６と連結ピン４とは一体に回転するため、連結ピン４は螺子孔３内を螺動し、この螺動に伴い前記カバー体６はこの連結ピン４と共に一方の対向端部２側に移動するが、連結ピン４が螺子孔３から脱落する前に前記一方の対向端部２と係止してカバー体６と連結ピン４の移動は共に阻止される。 When a force for rotating the cover body 6 is applied to the cover body 6 from the body 9 to be connected, the cover body 6 and the connection pin 4 rotate together, so that the connection pin 4 is screwed in the screw hole 3. The cover body 6 moves to the one opposing end 2 side together with the connecting pin 4 along with this screwing, but before the connecting pin 4 falls off from the screw hole 3, the cover body 6 is engaged with the one opposing end 2. Both the cover body 6 and the connection pin 4 are prevented from moving.

即ち、例え被連結体９から作用する力により前記カバー体６と連結ピン４とが回転して連結ピン４と螺子孔３との螺着が緩んだとしても、この連結ピン４の脱落を確実に阻止することができる。 That is, even if the cover body 6 and the connection pin 4 are rotated by the force acting from the connected body 9 and the connection between the connection pin 4 and the screw hole 3 is loosened, the connection pin 4 is surely removed. Can be prevented.

従って、この連結ピン４が被連結体９により回転せしめられても前記カバー体６がこの連結ピン４と一体で、しかも、このカバー体６が、連結ピン４が螺子孔３から脱落する前に対向端部２と係止することで、確実に対向端部２の取付孔部13からの脱落が阻止されるから、長期間安定的に被連結体９を連結できることになる。 Therefore, even when the connecting pin 4 is rotated by the connected body 9, the cover body 6 is integrated with the connecting pin 4, and before the connecting body 4 is removed from the screw hole 3. By locking with the opposing end 2, the falling of the opposing end 2 from the mounting hole 13 is reliably prevented, so that the connected body 9 can be stably connected for a long period of time.

更に、前記対向する取付孔部13の双方を螺子孔３とし、この螺子孔３に前記連結ピン４に設けた螺子部５を螺着することで、前記対向端部２間に連結ピン４を着脱自在に架設して前記開閉部を構成した場合には、この連結ピン４が取付孔部13に一層確実に取り付けられ、より一層強度が向上する。 Further, both of the mounting holes 13 facing each other are screw holes 3, and screw parts 5 provided on the connection pins 4 are screwed into the screw holes 3, thereby connecting the connection pins 4 between the opposing end parts 2. When the opening / closing part is constructed so as to be detachable, the connecting pin 4 is more reliably attached to the attachment hole part 13 and the strength is further improved.

特に、前記カバー体６を前記対向端部２間に略合致する形状とすれば、カバー体６が対向端部２に予め当接した構成となり、カバー体６に被連結体９からこのカバー体６（及び連結ピン４）を回転させようとする力が作用しても、予め当接するカバー体６と対向端部２との係止により、このカバー体６の回転は阻止される、即ち、このカバー体６により連結ピン４の回り止め作用が発揮されることになり、一層強度及び耐久性が向上する。 In particular, if the cover body 6 has a shape that substantially matches between the opposed end portions 2, the cover body 6 comes into contact with the opposed end portion 2 in advance, and this cover body is connected to the cover body 6 from the connected body 9. 6 (and the connecting pin 4), even if a force is applied to rotate, the cover body 6 is prevented from rotating by the engagement between the cover body 6 and the opposed end 2 that are in contact with each other in advance. The cover body 6 exerts a detent effect on the connecting pin 4 and further improves the strength and durability.

また、特殊な加工を一切必要としないため、連結ピン４として市販のボルトを採用することができ、極めてコスト安に上述の作用効果を得られることになる。 In addition, since no special processing is required, a commercially available bolt can be used as the connecting pin 4, and the above-described effects can be obtained at a very low cost.

また、例えば、カバー体６を、前記金具本体１の湾曲部７と対向する湾曲形状に設定し、このカバー体６と前記金具本体１の湾曲部７とを被連結体９を所定の位置に位置決めし得る位置決め部に設定することで、湾曲部７とカバー体６とで被連結体９を湾曲形状の底部に位置決めすることができ、この被連結体９を安定的に連結することができる。 Further, for example, the cover body 6 is set in a curved shape facing the curved portion 7 of the metal fitting body 1, and the cover body 6 and the curved portion 7 of the metal fitting main body 1 are placed at a predetermined position. By setting the positioning portion to be positioned, the coupled body 9 can be positioned on the curved bottom by the curved portion 7 and the cover body 6, and the coupled body 9 can be stably coupled. .

従って、本発明は、長期間安定して被連結体を連結し得る強度及び耐久性に秀れた極めて実用的な連結具となる。 Therefore, the present invention provides a very practical connector excellent in strength and durability that can stably connect the objects to be connected for a long period of time.

本発明の具体的な実施例１について図面に基づいて説明する。 A first embodiment of the present invention will be described with reference to the drawings.

実施例１は、略Ｕ字状の金具本体１の対向端部２に取付孔部13を対向状態に設け、この取付孔部13の一方は螺子孔３とし、この取付孔部13に連結ピン４を挿通すると共に、連結ピン４に設けた螺子部５を前記螺子孔３に螺着することで、前記対向端部２間に連結ピン４を着脱自在に架設して開閉部を構成し、この対向端部２間の連結ピン４にカバー体６を設け、このカバー体６は、前記螺子孔３を挿通しない外径であって、連結ピン４の螺子部５が螺着する螺子孔８を設けた螺子筒とし、この螺子孔８に前記螺子部５を螺着して連結ピン４にカバー体６を螺着被嵌することで、このカバー体６が前記連結ピン４と一体で回転し得るように構成すると共に、このカバー体６と共に前記連結ピン４が回転しようとした際、カバー体６と前記対向端部２とが係止して連結ピン４を抜け止めし得るように設定したものである。 In the first embodiment, a mounting hole 13 is provided in a facing state at the opposing end 2 of the substantially U-shaped metal fitting body 1, one of the mounting holes 13 is a screw hole 3, and a connecting pin is connected to the mounting hole 13. 4, and a screw portion 5 provided on the connecting pin 4 is screwed into the screw hole 3 to detachably connect the connecting pin 4 between the opposed end portions 2 to form an opening / closing portion, A cover body 6 is provided on the connecting pin 4 between the opposing ends 2, and the cover body 6 has an outer diameter that does not pass through the screw hole 3, and a screw hole 8 into which the screw portion 5 of the connecting pin 4 is screwed. The screw body 5 is screwed into the screw hole 8 and the cover body 6 is screwed into the connecting pin 4 so that the cover body 6 rotates integrally with the connecting pin 4. And the cover body 6 and the opposite end portion when the connecting pin 4 tries to rotate together with the cover body 6. Bets are those set so as to retaining the connecting pin 4 engages.

カバー体６は、連結ピン４に螺着被嵌することで、このカバー体６と連結ピン４とが一体で回転するように構成しているが、具体的には、このカバー体６が回転する際に、前記被連結体９からカバー体６を連結ピン４に押し付けるような力が作用しながら回転することで前記螺着により、このカバー体６のみが回転せずに、カバー体６と連結ピン４とが一体で回転するように構成している。 The cover body 6 is configured such that the cover body 6 and the connection pin 4 rotate integrally by being screwed onto the connection pin 4. Specifically, the cover body 6 is rotated. When the cover body 6 is rotated while a force that presses the cover body 6 against the connection pin 4 is acting from the connected body 9, only the cover body 6 does not rotate and the cover body 6 The connecting pin 4 is configured to rotate integrally.

また、予めカバー体６と対向端部２とが当接するように、このカバー体６として、前記対向端部２間に略合致するものが採用されている。 In addition, a cover body 6 that substantially matches between the facing end portions 2 is employed so that the cover body 6 and the facing end portion 2 abut in advance.

即ち、この螺子筒であるカバー体６の両端部が、常に前記対向端部２の内面と当接し、カバー体６の移動が阻止されることで、このカバー体６と一体の連結ピン４の回転も阻止されることになり、カバー体６により連結ピン４の回り止め作用が発揮されることになる。 That is, both end portions of the cover body 6 that is a screw cylinder always come into contact with the inner surface of the opposed end portion 2 and the movement of the cover body 6 is prevented, so that the connecting pin 4 integral with the cover body 6 The rotation is also prevented, and the cover body 6 exerts an anti-rotation action on the connecting pin 4.

従って、被連結体９によりカバー体６及びこのカバー体６と一体の連結ピン４に力が作用しても、前記カバー体６による回り止め作用により連結ピン４が回転しない、即ち、螺子孔３との螺着が緩まないため、極めて秀れた強度及び耐久性を示す。 Therefore, even if a force is applied to the cover body 6 and the connection pin 4 integral with the cover body 6 by the connected body 9, the connection pin 4 does not rotate due to the anti-rotation action by the cover body 6, that is, the screw hole 3 Since the screwing does not loosen, it exhibits extremely excellent strength and durability.

尚、カバー体６の回転を許容し得る場合には、このカバー体６として前記金具本体１の対向端部２間に配した際、このカバー体６の端部から前記対向端部２までの距離が、この対向端部２に夫々設けた螺子孔３の長さ以下となるものを採用すれば良く、この場合には、前記連結ピン４と螺子部３との螺着が緩む場合もあるが、例え緩んでも前記連結ピン４の取付孔部13からの脱落は確実に阻止される。 When the rotation of the cover body 6 can be permitted, when the cover body 6 is arranged between the opposing end portions 2 of the metal fitting body 1, the end of the cover body 6 to the opposing end portion 2 can be used. What is necessary is just to employ | adopt what the distance becomes below the length of the screw hole 3 each provided in this opposing edge part 2, In this case, the screwing of the said connection pin 4 and the screw part 3 may loosen. However, even if the connection pin 4 is loosened, the connection pin 4 is reliably prevented from falling off the mounting hole 13.

具体的には、このカバー体６の夫々の端部から対向端部２までの距離を合した長さが、この対向端部２に設けた螺子孔３の長さ以下となるように設定する。 Specifically, the length obtained by adding the distances from the respective end portions of the cover body 6 to the opposing end portion 2 is set to be equal to or shorter than the length of the screw hole 3 provided in the opposing end portion 2. .

即ち、このカバー体６が回転して連結ピン４が螺子孔３内を螺動しても、この連結ピン４と螺子孔３との螺着が解除される前に、このカバー体６が対向端部２に確実に係止してこの連結ピン４の脱落が確実に阻止される構成を、対向端部２間に略合致するカバー体６を用いずにコスト安に実現できる。 That is, even if the cover body 6 rotates and the connecting pin 4 is screwed in the screw hole 3, the cover body 6 is opposed before the screwing of the connecting pin 4 and the screw hole 3 is released. A configuration in which the connecting pin 4 is reliably prevented from falling off by being reliably locked to the end portion 2 can be realized at low cost without using the cover body 6 that substantially matches between the opposing end portions 2.

また、カバー体６を、前記略Ｕ字状の金具本体１の湾曲部７と対向する湾曲形状に設定し、このカバー体６と前記金具本体１の湾曲部７とを被連結体９を所定の位置に位置決めし得る位置決め部に設定している。 Further, the cover body 6 is set to a curved shape facing the curved portion 7 of the substantially U-shaped metal fitting body 1, and the cover body 6 and the curved portion 7 of the metal fitting body 1 are connected to the connected body 9 in a predetermined manner. It is set to a positioning part that can be positioned at the position.

従って、直線形状の連結ピンに直接被連結体を当接させて被連結体を連結する構成に比し、連結ピン４はカバー体６により金具本体１の湾曲部７と同様に秀れた位置決め作用及び応力分散作用を発揮できることになり、強度及び耐久性が向上し、長期間安定的に被連結体９を連結することができる。 Therefore, as compared with the configuration in which the coupled body is directly brought into contact with the linear coupling pin and the coupled body is coupled, the coupling pin 4 is excellently positioned by the cover body 6 in the same manner as the curved portion 7 of the metal fitting body 1. The action and the stress dispersion action can be exhibited, the strength and durability are improved, and the connected body 9 can be stably connected for a long period of time.

尚、カバー体６として、例えば直線形状等、湾曲形状でないものを採用しても良い。 In addition, as the cover body 6, you may employ | adopt what is not curved shapes, such as a linear shape.

連結ピン４としては、一方の対向端部２に螺子孔３がないため、連結ピン４のこの対向端部２と対応する部位には螺子部５がなく、基端部に摘子10を有する円筒形状のボルトを採用している。尚、連結ピン４として、螺子孔３がない一方の対向端部２と対応する部位に螺子部５が存する構成のものを採用しても良い。 Since the connecting pin 4 does not have the screw hole 3 at one opposing end 2, the connecting pin 4 does not have the screw 5 at the portion corresponding to the opposing end 2, and has a knob 10 at the base end. Cylindrical bolts are used. In addition, you may employ | adopt as a connection pin 4 the structure which has the screw part 5 in the site | part corresponding to the one opposing end part 2 which does not have the screw hole 3. FIG.

尚、連結ピン４は、対向端部２の螺子孔３及びカバー体６の螺子孔８と夫々螺着する螺子部５を有するものであれば、螺子部５が不連続に形成されているもの等、どんなものでも良いし、基端部に摘子10を有するものを採用しても良い。 In addition, if the connection pin 4 has the screw part 5 screwed with the screw hole 3 of the opposing end part 2 and the screw hole 8 of the cover body 6, the screw part 5 is formed discontinuously. Any one having a knob 10 at the proximal end may be adopted.

従って、実施例１は特殊な加工を施した（高価な）ボルトを用いる必要なく、市販のボルトを採用できる構成であり、極めてコスト安に強度及び耐久性を向上させることができる。 Therefore, Example 1 is a configuration in which a commercially available bolt can be adopted without using a specially processed (expensive) bolt, and the strength and durability can be improved at a very low cost.

また、実施例１においては、抜け止め用のパッキン11を連結ピン４の基端部に設けている。 Further, in the first embodiment, the packing 11 for preventing the removal is provided at the base end portion of the connecting pin 4.

尚、前記金具本体１の対向端部に設けた螺子孔３の一部（具体的には、外側端部）を圧潰変形させて、前記連結ピン４が挿通不能な抜け止め部を形成しても良く、この場合には、一層確実に連結ピン４を抜け止めできる構成となる。この抜け止め部は前記パッキン11が作用する螺子孔３と反対側の螺子孔３に設けるのが望ましい。 A part (specifically, the outer end) of the screw hole 3 provided at the opposite end of the metal fitting body 1 is crushed and deformed to form a retaining portion through which the connecting pin 4 cannot be inserted. In this case, the connection pin 4 can be more reliably prevented from coming off. This retaining portion is preferably provided in the screw hole 3 opposite to the screw hole 3 on which the packing 11 acts.

更に、このパッキン11の替わりに抜け止めリングを前記螺子孔３に設け、この抜け止めリングにより連結ピン４を抜け止めし得るように構成しても良い。 Further, a retaining ring may be provided in the screw hole 3 in place of the packing 11 so that the connecting pin 4 can be retained by the retaining ring.

実施例１は上述のように構成したから、複数の被連結体９を（開閉部を通じて）金具本体１の湾曲部７と、連結ピン４に螺着被嵌したカバー体６とに夫々当接させることで連結し、この被連結体９からカバー体６に、このカバー体６を回転させようとする力が作用した際、カバー体６と連結ピン４とは一体に回転しようとするが、カバー体６が回転する前に、カバー体６と対向端部２との係止により確実にこのカバー体６、即ち、連結ピン４の回転を阻止してこの連結ピン４と螺子孔３の螺着の緩みを確実に阻止することができ、極めて強度及び耐久性に秀れたものとなる。 Since the first embodiment is configured as described above, the plurality of coupled bodies 9 are brought into contact with the curved portion 7 of the metal fitting body 1 (through the opening / closing section) and the cover body 6 that is screwed onto the coupling pin 4. When the force to rotate the cover body 6 acts on the cover body 6 from the connected body 9, the cover body 6 and the connection pin 4 try to rotate integrally. Before the cover body 6 rotates, the cover body 6, that is, the connection pin 4 is reliably prevented from rotating by the engagement between the cover body 6 and the opposite end 2, and the connection pin 4 and the screw hole 3 are screwed. It is possible to reliably prevent loosening of wear, and it is extremely excellent in strength and durability.

即ち、カバー体６により連結ピン４が回り止めされて確実にこの連結ピン４の緩みを阻止できると共に、特殊で手間のかかる加工を一切必要としないため、連結ピン４として安価な市販のボルトを採用することができ、従って、コスト安に長期間安定して被連結体を連結し得る強度及び耐久性に秀れた極めて実用的な連結具となる。 That is, since the connecting pin 4 is prevented from rotating by the cover body 6 and the connecting pin 4 can be reliably prevented from loosening, and no special and troublesome processing is required, an inexpensive commercially available bolt is used as the connecting pin 4. Therefore, it is a very practical connector that is excellent in strength and durability that can stably connect the objects to be connected for a long time at low cost.

また、図３，４は、前記金具本体１の対向端部２の双方に螺子孔３を設けた構成の実施例１の別例であって、具体的には、略Ｕ字状の金具本体１の対向端部２に取付孔部13を対向状態に設け、この取付孔部13の双方を螺子孔３とし、この螺子孔３に前記連結ピン４に設けた螺子部５を螺着することで、前記対向端部２間に連結ピン４を着脱自在に架設して前記開閉部を構成し、この対向端部２間の連結ピン４にカバー体６を設け、このカバー体６は、前記螺子孔３を挿通しない外径であって、連結ピン４の螺子部５が螺着する螺子孔８を設けた螺子筒とし、この螺子孔８に前記螺子部５を螺着して連結ピン４にカバー体６を螺着被嵌することで、このカバー体６が前記連結ピン４と一体で回転し得るように構成すると共に、このカバー体６と共に前記連結ピン４が回転しようとした際、カバー体６と前記対向端部２とが係止して連結ピン４を抜け止めし得るように設定したものであり、対向端部２の双方の螺子孔３に連結ピン４に設けた螺子部５を夫々螺着しているから、一方のみに螺子孔３を設けた場合より一層強度に秀れた構成である。 3 and 4 show another example of the first embodiment in which the screw holes 3 are provided on both the opposite end portions 2 of the metal fitting body 1, and specifically, a substantially U-shaped metal fitting body. A mounting hole portion 13 is provided in a facing state at one opposing end 2, both of the mounting hole portions 13 serve as screw holes 3, and a screw portion 5 provided on the connecting pin 4 is screwed into the screw hole 3. Thus, a connecting pin 4 is detachably installed between the opposing end portions 2 to constitute the opening / closing portion, and a cover body 6 is provided on the connecting pin 4 between the opposing end portions 2, A screw cylinder having an outer diameter that does not pass through the screw hole 3 and having a screw hole 8 into which the screw portion 5 of the connecting pin 4 is screwed is formed. The screw portion 5 is screwed into the screw hole 8 to connect the connecting pin 4. The cover body 6 is screwed and fitted to the cover body 6 so that the cover body 6 can rotate integrally with the connecting pin 4, and When the connecting pin 4 is about to rotate, the cover body 6 and the opposed end 2 are locked so that the connecting pin 4 can be prevented from coming off. Since the screw portions 5 provided on the connecting pin 4 are screwed into the screw holes 3, respectively, the structure is superior in strength to the case where the screw holes 3 are provided only on one side.

この別例においては、外周面を螺子部５に設定し、基端部に孔12が形成された円筒形状のボルトを採用している。具体的には、この六角形の孔12を形成している。尚、この孔12として、四角形等の他の形状を採用しても良い。 In this other example, a cylindrical bolt in which the outer peripheral surface is set to the screw portion 5 and the hole 12 is formed in the base end portion is employed. Specifically, this hexagonal hole 12 is formed. The hole 12 may have another shape such as a quadrangle.

また、別例においては、双方の対向端部２と螺着されることで、一層確実に連結ピン４を取り付けられるため、この連結ピン４にはパッキン11を設けていない一般的な市販のボルトをそのまま採用している。尚、パッキン11を設けた連結ピン４を採用しても良い。 In another example, since the connecting pin 4 can be more securely attached by being screwed to both the opposite end portions 2, a general commercially available bolt in which no packing 11 is provided on the connecting pin 4. Is adopted as it is. The connecting pin 4 provided with the packing 11 may be adopted.

実施例２は、図５，６に図示したように実施例１においては略Ｕ字状であった金具本体１を略Ｃ字状としたものである。尚、実施例１と同一構成部分には同一符号を付した。 In the second embodiment, as shown in FIGS. 5 and 6, the metal fitting body 1 that is substantially U-shaped in the first embodiment is formed into a substantially C-shape. In addition, the same code | symbol was attached | subjected to the same component as Example 1. FIG.

具体的には、実施例２は、前記金具本体１の対向端部２間に架設した連結ピン４と、この連結ピン４と対向する湾曲部７とに主に前記被連結体９を位置せしめる実施例１と異なり、この連結ピン４に対する左右位置内面に前記被連結体９が当接する当接部としての湾曲部７を設けて、この対向する湾曲部７に夫々被連結体９を位置せしめる構成である。 Specifically, in the second embodiment, the connected body 9 is mainly positioned on the connecting pin 4 provided between the facing end portions 2 of the metal fitting body 1 and the curved portion 7 facing the connecting pin 4. Unlike the first embodiment, a curved portion 7 is provided as an abutting portion with which the coupled body 9 abuts on the inner surface of the left and right positions with respect to the coupling pin 4, and the coupled bodies 9 are respectively positioned on the opposing curved portions 7. It is a configuration.

即ち、実施例１のように湾曲部７をカバー体６に設けた構成でなく、このカバー体６及び連結ピン４に被連結体９からの荷重が常に作用する構成ではないから、一層強度に秀れた構成となる。 That is, it is not the structure which provided the curved part 7 in the cover body 6 like Example 1, but the structure from which the load from the to-be-connected body 9 acts on this cover body 6 and the connection pin 4 always, Therefore It becomes stronger. Excellent composition.

尚、更にカバー体６及び金具本体１にしてこのカバー体６との対向位置に湾曲部７を形成し、例えば４本の被連結体９を夫々湾曲部７に位置決めして連結し得る構成としても良い。 Further, the cover body 6 and the metal fitting body 1 are further formed with a curved portion 7 at a position facing the cover body 6, and for example, four connected bodies 9 can be positioned and connected to the curved portion 7. Also good.

また、実施例１に比し、金具本体１の内面形状がより楕円形状に近似することから、被連結体９の位置決め作用が一層良好に発揮され、被連結体９をより一層安定的に連結することができることになる。 Moreover, since the inner surface shape of the metal fitting body 1 approximates to an elliptical shape as compared with the first embodiment, the positioning action of the coupled body 9 is more satisfactorily performed, and the coupled body 9 is more stably coupled. Will be able to.

また、この連結ピン４は、前記金具本体１の対向端部２に設けた取付孔部13の螺子部３との螺合により、前記湾曲部７に位置せしめられた被連結体９による引っ張り荷重を受けることになる。従って、図５，６においては、金具本体１の対向端部２に設けた取付孔部13の一方に螺子部３を設けた構成としているが、双方に設けた場合にはより強度及び耐久性に秀れた構成となる。 Further, the connecting pin 4 is pulled by the connected body 9 positioned on the curved portion 7 by screwing with the screw portion 3 of the mounting hole portion 13 provided at the opposite end portion 2 of the metal fitting body 1. Will receive. Accordingly, in FIGS. 5 and 6, the screw portion 3 is provided in one of the mounting hole portions 13 provided in the opposed end portion 2 of the metal fitting body 1. However, when both are provided, the strength and durability are further increased. The composition is excellent.

また、実施例１においては金具本体１を略Ｕ字状とし、実施例２においては略Ｃ字状としているが、一側が開口した形状であればどのような形状の金具本体１を採用しても良い。この場合、内面に湾曲部を有する形状を採用することで、この湾曲部により被連結体の位置決め作用が発揮され、連結を一層良好に行えることになる。 In the first embodiment, the metal fitting body 1 is substantially U-shaped, and in the second embodiment, the metal fitting body 1 is substantially C-shaped. Also good. In this case, by adopting a shape having a curved portion on the inner surface, the curved portion exhibits the positioning action of the connected body, and the connection can be performed more satisfactorily.

その余は実施例１と同様である。 The rest is the same as in Example 1.

本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
