Description

本発明は、工具を使用する際などに、工具の落下防止などを図るうえで好適に使用することができる連結具に関する。   The present invention relates to a connector that can be suitably used to prevent the tool from dropping when the tool is used.

工具を使用する際に、工具を手元から落下させてしまうのを防止するため、工具に紐や鎖、ロープなどの索体を接続する場合にあって、工具と索体とを接続する部分へ使用する落下防止具が知られている(特許文献1参照)。この公知の落下防止具は、工具まわりへ巻き付けるために輪状に形成した紐状部分を有し、この紐状部分の輪の根本に圧着スリーブを嵌め付けたものとなっている。
工具が落下しようとするとき、輪状に形成した紐状部分には工具の軸方向と交差する向きに力が加わり、この輪状部分が工具を締め付けるので、工具から外れず、従ってこの落下防止具に接続された索体の他端部を作業者へ繋いでおけば、結果として工具の落下が防止されると説明されている。
特開2007−53835号公報
To prevent the tool from dropping from the hand when using the tool, when connecting cords such as strings, chains, and ropes to the tool, to the part where the tool and cord are connected A fall prevention tool to be used is known (see Patent Document 1). This known fall prevention tool has a string-like portion formed in a ring shape to be wound around a tool, and a crimp sleeve is fitted to the root of the ring of the string-like portion.
When the tool is about to fall, a force is applied to the ring-shaped string-shaped portion in a direction crossing the axial direction of the tool, and this ring-shaped portion tightens the tool, so that it does not come off from the tool. It is described that if the other end of the connected cable body is connected to an operator, the tool is prevented from falling as a result.
JP 2007-53835 A

上記した従来公知の落下防止具では、輪状に形成した紐状部分に対して、工具の軸方向と交差する向きに力が加わったときに工具への締め付け作用を生じさせるようにしてあるが、もし、この締め付け作用が弱いと、輪状の紐状部分から工具が抜け出してしまうことが容易に予測される。すなわち、工具に対する確実な落下防止作用を得るためには、工具において細く括れた棒状部が形成されていなければならず、且つこの括れ部分へ輪状の紐状部分を巻き付ける必要がある。
このようなことから、適用できる工具として、その外形状が特定されてしまう(汎用性が制限されてしまう)ことになる。また工具に対して輪状の紐状部分を巻き付け、その後で圧着スリーブの嵌め付けを行わなければならないため、工具への着脱が極めて面倒であるという欠点があった。
In the above-described conventionally known fall prevention device, when a force is applied to the string-shaped portion formed in a ring shape in a direction crossing the axial direction of the tool, a tightening action to the tool is generated. If this tightening action is weak, it is easily predicted that the tool will slip out of the ring-shaped string-like portion. That is, in order to obtain a reliable fall prevention effect on the tool, it is necessary that a narrow bar-shaped portion is formed in the tool, and it is necessary to wind a ring-shaped string-like portion around the constricted portion.
For this reason, the outer shape of the applicable tool is specified (the versatility is limited). Moreover, since it has to wind a ring-shaped string-shaped part around a tool and after that, a crimping sleeve must be fitted, there is a drawback that it is very troublesome to attach and detach to the tool.

本発明は、上記事情に鑑みてなされたものであって、工具に対する着脱が簡単且つ迅速に行えると共に、工具の外形状に関する制限を緩和して汎用性を拡大できるようにした連結具を提供することを目的とする。   The present invention has been made in view of the above circumstances, and provides a connecting tool that can be easily and quickly attached to and detached from a tool, and that can relax restrictions on the outer shape of the tool and expand versatility. For the purpose.

前記目的を達成するために、本発明は次の手段を講じた。
即ち、本発明に係る連結具1は、バネ特性を有する素材を1巻き以上のコイル形状にすることによって工具Wの棒状部Gにその端部から嵌合しかつ挟持する嵌着部2と、前記素材の両端部が嵌着部2の外周側へ突出されていて遠近移動により前記嵌着部2を拡縮させる一対のツマミ部3,4とが形成され、前記一対のツマミ部3,4の少なくとも一方に索体5を接続するための接続部6が形成されている。
このような構成とすれば、嵌着部2を拡径させる方向へ向けて一対のツマミ部3,4を遠近移動させ、そのまま嵌着部2を工具Wの棒状部Gへ嵌合させた後、ツマミ部3,4の遠近移動を解除するだけで、嵌着部2を工具Wの棒状部Gへ挟持状態とさせることができる。この挟持状態とさせることで工具Wと嵌着部2とを離脱不能にできるので、ツマミ部3,4のうち少なくとも一方に対して設けられた接続部6へ索体5を接続し、この索体5の他端部を作業者などに繋いでおくことで、作業者からの工具Wの離脱(落下や紛失など)を防止できることになる。
In order to achieve the above object, the present invention has taken the following measures.
That is, the connector 1 according to the present invention includes a fitting portion 2 that fits and sandwiches the rod-like portion G of the tool W from its end portion by forming a material having spring characteristics into a coil shape of one or more turns. Both ends of the material protrude to the outer peripheral side of the fitting portion 2 and a pair of knob portions 3 and 4 are formed to expand and contract the fitting portion 2 by perspective movement. A connecting portion 6 for connecting the cable body 5 to at least one is formed.
With such a configuration, after the pair of knob portions 3 and 4 are moved in the distance direction in the direction in which the fitting portion 2 is expanded in diameter, the fitting portion 2 is fitted to the rod-like portion G of the tool W as it is. The fitting part 2 can be clamped to the rod-like part G of the tool W only by releasing the perspective movement of the knob parts 3 and 4. Since the tool W and the fitting portion 2 can be made unseparable by making this sandwiched state, the cable body 5 is connected to the connection portion 6 provided for at least one of the knob portions 3 and 4, and this cord By connecting the other end of the body 5 to an operator or the like, it is possible to prevent the tool W from being detached (dropped or lost) from the operator.

嵌着部2の素材は、板バネ又は線バネで形成されたものとすることができる。
嵌着部2内に、嵌着部2の拡縮により内径が弾力的に拡縮可能な挟持補助体7が内嵌されたものとすることができる。
このような挟持補助体7を用いると、工具Wの棒状部Gが嵌着部2の内径よりも細い場合にも挟持補助体7を介して嵌着部2を嵌め付け、確実な挟持状態にすることができる(挟持補助体7にスペーサ的作用を生じさせることができる)。また、この挟持補助体7により、工具Wの棒状部Gに対する滑止め効果や傷つき防止効果などを得ることもできる利点がある。
The material of the fitting part 2 can be formed of a leaf spring or a wire spring.
In the fitting part 2, the clamping auxiliary body 7 whose inner diameter can be elastically expanded / contracted by expansion / contraction of the fitting part 2 can be internally fitted.
When such a sandwiching auxiliary body 7 is used, even when the rod-like part G of the tool W is thinner than the inner diameter of the fitting part 2, the fitting part 2 is fitted through the sandwiching auxiliary body 7 so that a reliable clamping state is achieved. (It is possible to cause a spacer-like action on the sandwiching assisting body 7). In addition, the sandwiching assisting body 7 has an advantage that it is possible to obtain a non-slip effect or a damage prevention effect on the rod-like portion G of the tool W.

挟持補助体7には、周方向の1箇所を分断する拡縮用隙間22が形成されたものとすることができる。また挟持補助体7には、軸方向の少なくとも一端に径方向外方へ張り出して前記嵌着部2に軸方向に係合するフランジ部21が形成されたものとすることができる。
拡縮用隙間22の形成は、挟持補助体7の内径を拡縮させ易くさせるうえで有益となる。またフランジ部21の形成は、嵌着部2に対する挟持補助体7の確実な装着と位置ズレ防止効果を得るうえで有益となる。
The sandwiching assisting body 7 may be formed with an expansion / contraction gap 22 that divides one place in the circumferential direction. Further, the sandwiching auxiliary body 7 may be formed with a flange portion 21 that protrudes radially outward at at least one end in the axial direction and engages the fitting portion 2 in the axial direction.
The formation of the expansion / contraction gap 22 is beneficial in making it easy to expand / contract the inner diameter of the sandwiching assisting body 7. Further, the formation of the flange portion 21 is beneficial in obtaining a reliable attachment of the holding auxiliary body 7 to the fitting portion 2 and an effect of preventing displacement.

本発明に係る連結具では、工具に対する着脱が簡単且つ迅速に行えると共に、工具の外形状に関する制限を緩和して汎用性を拡大できる。   The connector according to the present invention can be easily and quickly attached to and detached from the tool, and the versatility can be expanded by relaxing restrictions on the outer shape of the tool.

以下、本発明の実施の形態を、図面に基づき説明する。
図1乃至図5は、本発明に係る連結具1の第1実施形態を示している。なお、図例では工具Wがラジオペンチである場合を示しており、連結具1を装着する棒状部Gは、いずれか一方のグリップ部ということになる。
この連結具1は、嵌着部2と、一対のツマミ部3,4とを有して形成されたもので、少なくとも一方のツマミ部(図例ではツマミ部3)に、紐や鎖、ワイヤ、ロープ、或いは樹脂製又は金属製のコイル紐などの索体5を接続するための接続部6が形成されている。また本第1実施形態の連結具1では、嵌着部2内に挟持補助体7が内嵌されたものとしてある。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show a first embodiment of a connector 1 according to the present invention. In the example shown in the figure, the tool W is a radio pliers, and the rod-like part G to which the connector 1 is attached is one of the grip parts.
This connector 1 is formed to have a fitting portion 2 and a pair of knob portions 3 and 4, and at least one knob portion (knob portion 3 in the illustrated example) has a string, a chain, and a wire. A connecting portion 6 for connecting a rope 5 or a cable body 5 such as a resin or metal coil string is formed. Moreover, in the connector 1 of this 1st Embodiment, the clamping assistance body 7 shall be internally fitted in the fitting part 2. FIG.

嵌着部2は、バネ特性を有する素材を1巻き以上のコイル形状にすることによって形成されている。本第1実施形態では素材に帯状をした所定長さの板バネを用いてあり、この板バネの一方の端部2a寄りには板中央に沿って長孔10を形成すると共に、板バネの他方の端部2b寄りには長孔10へ通過可能となる細い板幅のくびれ部11を形成し、このくびれ部11を長孔10へ通した両端部が交差するようにしてある。
一対のツマミ部3,4は、素材(バネ板)における両側の端部2a,2bのうち、長孔10とくびれ部11とで交差させた後、嵌着部2の外周側へ突出する部分で形成させてある。なお、これら突出部分を互いに寄せ合うような方向で折り曲げることにより、両側のツマミ部3,4を摘み易くさせるのが好適である。
The fitting portion 2 is formed by forming a material having spring characteristics into a coil shape of one or more turns. In the first embodiment, a strip-shaped plate spring having a predetermined length is used as the material, and a long hole 10 is formed near the one end 2a of the plate spring along the center of the plate. Near the other end 2b is formed a narrow plate width narrow portion 11 that can pass through the long hole 10, and both ends of the narrow portion 11 passing through the long hole 10 intersect each other.
The pair of knob portions 3 and 4 are portions projecting toward the outer peripheral side of the fitting portion 2 after intersecting the elongated hole 10 and the constricted portion 11 among the end portions 2a and 2b on both sides of the material (spring plate). It is formed with. In addition, it is preferable that the knobs 3 and 4 on both sides are easily picked by bending these protruding portions in a direction in which the protruding portions are brought close to each other.

このようなことから、両側のツマミ部3,4を摘むように操作力を加えると、長孔10とくびれ部11とが交差して嵌着部2の外周側へ突出する量を減少させつつ両ツマミ部3,4が相対近接する方向へ移動するようになり、嵌着部2を形成させている素材が弾力に抗しつつ縮径するようになる。
また、このように嵌着部2が縮径された状態から両ツマミ部3,4への操作力を弛緩乃至解除すると、嵌着部2に対して蓄えられた弾力が復元作用を起こすことで、長孔10とくびれ部11とが交差して嵌着部2の外周側へ突出する量を増加させつつ両ツマミ部3,4は相対離反する方向へ移動し、嵌着部2は拡径するようになる。
For this reason, when an operating force is applied so as to grip the knobs 3 and 4 on both sides, the length of the elongated hole 10 and the constricted part 11 intersecting each other while reducing the amount protruding to the outer peripheral side of the fitting part 2. The knob portions 3 and 4 are moved in the direction in which they are relatively close to each other, and the diameter of the material forming the fitting portion 2 is reduced while resisting elasticity.
Further, when the operating force applied to both the knob portions 3 and 4 is relaxed or released from the state in which the fitting portion 2 is reduced in diameter in this way, the elastic force stored in the fitting portion 2 causes a restoring action. While the elongated hole 10 and the constricted portion 11 cross each other and increase the amount projecting to the outer peripheral side of the fitting portion 2, both the knob portions 3 and 4 move in a direction away from each other, and the fitting portion 2 has an enlarged diameter. To come.

このようにして、ツマミ部3,4を互いに遠近移動させることにより、嵌着部2が拡縮することになる。なお、素材とする板バネは、バネ鋼製とすればよいが、構造的又は材質的に十分なバネ特性が得られる場合は樹脂製等とすることも可能である。
なお、図例では、くびれ部11を設けた方の端部2bを部分的に幅広に形成させ、長孔10を設けた方の端部2aと同じ幅にすることで、ツマミ部3,4の形状を揃えさせ、もってこれらツマミ部3,4へ指を掛けたり摘み操作のために力を伝えたりすることが容易且つ確実に行えるようにしてある。
Thus, the fitting part 2 will be expanded / contracted by moving the knob parts 3 and 4 to each other. The leaf spring used as a material may be made of spring steel, but may be made of resin or the like if sufficient spring characteristics are obtained structurally or materially.
In the example shown in the figure, the end portion 2b on which the constricted portion 11 is provided is partially formed to be wide and has the same width as the end portion 2a on which the elongated hole 10 is provided, so that the knob portions 3 and 4 are provided. Therefore, it is possible to easily and surely place a finger on these knob portions 3 and 4 and transmit a force for a picking operation.

接続部6は、ツマミ部3に丸孔を貫通させることで形成してあり、索体5にはその接続側の端部に適宜接続金具15,16を連結させてある。なお接続部6は、他方のツマミ部4に設けることもでき、場合によっては両方のツマミ部3,4に設けることも可能である。
挟持補助体7は、嵌着部2にガタツキ無く内嵌可能となる円筒状の本体部20と、この本体部20における軸方向の両端部から径方向外方へ張り出したフランジ部21とを有して形成されている。本体部20の内径は、工具Wの棒状部Gに対してガタツキ無く嵌合できる寸法(僅かな径大又は径小を含む同等寸法)として形成されており、また本体部20の長さ(両フランジ部21間の内法寸法)は嵌着部2の軸方向長さと略同じか僅かに大きい程度の寸法として形成されている。
The connecting portion 6 is formed by penetrating a round hole in the knob portion 3, and connecting cords 15 and 16 are appropriately connected to the end portion on the connecting side of the cord body 5. The connecting portion 6 can also be provided on the other knob portion 4, and in some cases, can be provided on both knob portions 3 and 4.
The sandwiching assisting body 7 has a cylindrical main body portion 20 that can be fitted in the fitting portion 2 without rattling, and a flange portion 21 that protrudes radially outward from both axial end portions of the main body portion 20. Is formed. The inner diameter of the main body 20 is formed as a dimension that can be fitted to the rod-shaped part G of the tool W without rattling (equivalent dimensions including a slight large diameter or a small diameter), and the length of the main body 20 (both The internal dimension between the flange portions 21) is formed as a size that is substantially the same as or slightly larger than the axial length of the fitting portion 2.

本体部20には、周方向の1箇所を分断する拡縮用隙間22が形成されている。また両側のフランジ部21は、本体部20を嵌着部2へ内嵌することによって嵌着部2の軸方向両端部に係合するような張出寸法で形成されている。そして、これら本体部20及びフランジ部21は、ゴムや軟質樹脂などの弾性材により一体的に形成されており、この挟持補助体7(本体部20)を嵌着部2へ内嵌させた状態で嵌着部2を拡縮させると、この嵌着部2の拡縮に伴って当該挟持補助体7の内径も、弾力的に拡縮するようになる。
このような構成の連結具1を使用するには、まず、ツマミ部3,4を相対近接方向へ摘み、嵌着部2と共にこの嵌着部2に内嵌された挟持補助体7の内径を拡径させる。この状態のまま、挟持補助体7の本体部20を工具Wの棒状部Gにその端部から嵌合させ、棒状部Gの適当な位置でツマミ部3,4への摘み操作を解除させる。
An expansion / contraction gap 22 is formed in the main body 20 to divide one place in the circumferential direction. Further, the flange portions 21 on both sides are formed with an overhanging dimension so as to engage with both end portions in the axial direction of the fitting portion 2 by fitting the main body portion 20 into the fitting portion 2. And these main-body parts 20 and the flange part 21 are integrally formed by elastic materials, such as rubber | gum and soft resin, The state which made this fitting auxiliary body 7 (main-body part 20) fit in the fitting part 2 internally. When the fitting portion 2 is expanded and contracted, the inner diameter of the clamping auxiliary body 7 is also elastically expanded and contracted as the fitting portion 2 expands and contracts.
In order to use the connector 1 having such a configuration, first, the knob portions 3 and 4 are picked in the relative proximity direction, and the inner diameter of the holding auxiliary body 7 fitted into the fitting portion 2 together with the fitting portion 2 is set. Increase the diameter. In this state, the main body portion 20 of the sandwiching assisting body 7 is fitted to the rod-shaped portion G of the tool W from its end, and the knob operation to the knob portions 3 and 4 is released at an appropriate position of the rod-shaped portion G.

こうすることで、嵌着部2の弾力により、当該嵌着部2と共に挟持補助体7の内径が縮径し、挟持補助体7の内周面が工具Wの棒状部Gに圧接される。従って、工具Wの棒状部Gに対してこの連結具1が位置ズレすることも離脱することもなく、しっかりと結合した状態となる。
ツマミ部3の接続部6に適宜接続金具15,16を介すか又は介さないで索体5を接続した状態とし、この索体5の他端部を作業者側へ繋いでおけば、作業者からの工具Wの離脱(落下や紛失など)を防止できることになる。
In this way, due to the elasticity of the fitting part 2, the inner diameter of the clamping auxiliary body 7 is reduced together with the fitting part 2, and the inner peripheral surface of the clamping auxiliary body 7 is pressed against the rod-like part G of the tool W. Therefore, the connecting tool 1 is not displaced or separated from the rod-like portion G of the tool W, and is firmly connected.
If the cable body 5 is properly connected to the connection part 6 of the knob part 3 with or without the connection fittings 15 and 16, and the other end of the cable body 5 is connected to the operator side, the operator It is possible to prevent the tool W from being detached (dropped or lost).

ところで、挟持補助体7は、工具Wの重さ、形体、用途、及び工具Wにおける棒状部Gの太さなどに応じて、使用したり使用しなかったりを適宜選択できるものである。そのため、嵌着部2の内径が種々に異なるものや、挟持補助体7の内径が種々に異なるものなどを予め製作し、準備しておくのが好適となる。
また、図6及び図7に示すように、例えば工具Wがドライバーなどの回転操作を必要とするものである場合には、工具Wの棒状部Gに対してベアリングなどの回転自在なスリーブ部材30を嵌着させ、このスリーブ部材30の外周側に嵌着部2を直接的、又は挟持補助体7を介して間接的に嵌着させるようにすればよい。
By the way, the sandwiching assisting body 7 can be appropriately used or not used depending on the weight of the tool W, the shape, the application, the thickness of the rod-like portion G in the tool W, and the like. For this reason, it is preferable to prepare and prepare in advance those in which the inside diameter of the fitting portion 2 is variously different, and those in which the inside diameter of the sandwiching auxiliary body 7 is variously different.
Also, as shown in FIGS. 6 and 7, for example, when the tool W requires a rotating operation such as a screwdriver, a rotatable sleeve member 30 such as a bearing with respect to the rod-shaped portion G of the tool W is used. And the fitting portion 2 may be fitted directly or indirectly via the sandwiching assisting body 7 on the outer peripheral side of the sleeve member 30.

このようなスリーブ部材30を使用すれば、連結具1が索体5によって回転を制限される状況下にあっても、スリーブ部材30を介して工具Wを回転自在な状態に保持できるので、工具Wの使用上、不便を感じることはなくなる。
なお、スリーブ部材30についても、工具Wの棒状部Gに対して着脱自在とすることができるため、工具Wへの特別な加工などは不要である。
図8は、本発明に係る連結具1の第2実施形態を示している。本第2実施形態の連結具1は、嵌着部2を形成する素材として線バネが採用されたものである。図例では、線バネを2巻きさせることで嵌着部2を形成させてある。また、嵌着部2を形成させる途中(2巻きさせる途中)で、線バネを嵌着部2から径方向外方へ突出させるようにしてツマミ部3及びツマミ部4を形成させてあり、これら嵌着部2及び両ツマミ部3,4の一体化を可能にしてある。
If such a sleeve member 30 is used, the tool W can be held in a rotatable state via the sleeve member 30 even in a situation where the rotation of the connector 1 is restricted by the cable body 5. There is no inconvenience in using W.
Note that the sleeve member 30 can also be freely attached to and detached from the rod-like portion G of the tool W, so that special processing or the like on the tool W is unnecessary.
FIG. 8 shows a second embodiment of the connector 1 according to the present invention. In the connector 1 of the second embodiment, a wire spring is adopted as a material for forming the fitting portion 2. In the illustrated example, the fitting portion 2 is formed by winding the wire spring twice. Further, in the middle of forming the fitting portion 2 (in the middle of two windings), the knob portion 3 and the knob portion 4 are formed so that the wire spring protrudes radially outward from the fitting portion 2. The fitting part 2 and both knob parts 3 and 4 can be integrated.

そして一方のツマミ部3では、嵌着部2から突出する根本部にカシメ用の圧着具31を取り付けることで、この圧着具31より先方側に形成される輪部で索体5用の接続部6が形成されるようにしてある。
本第2実施形態の連結具1における使用状況(挟持補助体7を必要に応じて使用したり使用しなかったりできる点を含む)や作用効果は、上記した第1実施形態の場合と略同様であるため、ここでの詳説は省略する。
本発明は、上記各実施形態に限定されるものではなく、実施の形態に応じて適宜変更可能である。
And in one knob part 3, by attaching the crimping tool 31 for caulking to the root part which protrudes from the fitting part 2, the connection part for the rope body 5 by the ring part formed ahead of this crimping tool 31 6 is formed.
The usage status (including the point that the clamping assisting body 7 can be used or not used as necessary) and the effects in the connector 1 of the second embodiment are substantially the same as those of the first embodiment described above. Therefore, the detailed explanation here is omitted.
The present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.

例えば、嵌着部2の巻き形状やツマミ部3,4の突出角度、挟持補助体7の形状などは何ら限定されるものではない。またこれらを形成する素材としても、所定の弾力を有するものであればその他は特に限定されるものではない。
挟持補助体7において、フランジ部21は本体部20に対する一端側のみとしてもよいし、設けないようにしてもよい。
For example, the winding shape of the fitting portion 2, the protrusion angle of the knob portions 3 and 4, the shape of the sandwiching auxiliary body 7, etc. are not limited at all. Also, the material for forming these is not particularly limited as long as it has a predetermined elasticity.
In the clamping auxiliary body 7, the flange portion 21 may be provided only on one end side with respect to the main body portion 20, or may not be provided.
