Abstract

<P>PROBLEM TO BE SOLVED: To provide a tool fall preventing device which can positively connect a rope member to a tool even if the tool has no section to which one end of the rope member is directly connectable. <P>SOLUTION: The tool fall preventing device has a cylindrical tool connection portion 11 to which a rope 2 is connected, and a grip portion 1a of the tool 1 is inserted into the tool connection portion 11, followed by bonding the tool connection portion 11 to an outer peripheral surface of the grip portion 1a, to thereby connect the tool 1 and the tool connection portion 11 together. Thus even if the tool 1 has no annular portion to which a hook 2a of the rope 2 is directly connected, the rope 2 can be connected to the tool 1. In this case, the tool connection portion 11 is expandable in a radial direction of the grip portion 1a, and therefore by radially expanding the tool connection portion 11, attachment/detachment thereof to/from the tool 1 is facilitated, which leads to application of the tool fall preventing device to tools having different radial dimensions. Further, since the tool connection portion 11 is cylindrically formed, the grip portion 1a of the tool 1 can be gripped from above the tool connection portion 11 without discomfort sense. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、例えば工事現場等で使用される各種工具に用いられ、工具の落下を防止するための工具落下防止具に関するものである。   The present invention relates to a tool fall prevention tool for use in various tools used at, for example, construction sites and the like to prevent the tool from dropping.

一般に、建設工事現場等の作業者は、所定の作業を行うための各種の工具を所持しており、工具を使用しないときは作業者の身体に装着したホルダ等に収納している。しかしながら、作業中等に誤って工具を落下させる場合があるため、例えば両端にそれぞれフックを有するロープの一端を作業者の身体側に連結し、ロープの他端を工具に連結することにより、万一工具を落下させた場合でも工具をロープによって作業者に繋ぎ止めるようにしている（例えば、特許文献１参照。）。
特開２００２−２６２９１９号公報 In general, an operator at a construction site or the like possesses various tools for performing a predetermined operation, and stores the tool in a holder or the like attached to the worker's body when the tool is not used. However, since the tool may be accidentally dropped during work or the like, for example, by connecting one end of a rope having hooks at both ends to the body side of the operator and connecting the other end of the rope to the tool, Even when the tool is dropped, the tool is secured to the worker by a rope (see, for example, Patent Document 1).
JP 2002-262919 A

しかしながら、前述のようにロープを用いて工具を連結する場合、ロープのフックは作業者の身体側の連結部（例えば、安全帯の環状金具等）に連結することができるが、工具によってはロープのフックを連結可能な環状部分を有していないものが多く、このような工具にはロープのフックを直接連結することができないという問題点があった。   However, when a tool is connected using a rope as described above, the hook of the rope can be connected to a connecting portion on the body side of the worker (for example, an annular bracket of a safety belt). Many of these tools do not have an annular portion to which the hook can be connected, and such a tool has a problem that the rope hook cannot be directly connected.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、ロープ状部材の一端を直接連結可能な部分を有していない工具であっても、ロープ状部材を確実に連結することのできる工具落下防止具を提供することにある。   The present invention has been made in view of the above problems, and the object of the present invention is to ensure that the rope-shaped member is secured even in a tool that does not have a portion that can directly connect one end of the rope-shaped member. It is providing the tool fall prevention tool which can be connected.

本発明は前記目的を達成するために、一端側に工具使用者の把持する把持部を備えた工具に装着され、工具使用者の身体側にロープ状部材を介して連結される工具落下防止具において、前記ロープ状部材が一端に連結される工具連結部を備え、工具連結部を把持部の外周面に被着可能な筒状の部材によって径方向に伸縮自在に形成している。   In order to achieve the above object, the present invention provides a tool fall prevention tool that is attached to a tool having a gripping part that is gripped by a tool user on one end side and is connected to the body side of the tool user via a rope-shaped member. The rope-like member includes a tool connecting portion connected to one end, and the tool connecting portion is formed to be extendable in the radial direction by a cylindrical member that can be attached to the outer peripheral surface of the gripping portion.

これにより、ロープ状部材が連結される筒状の工具連結部に工具の把持部を挿入し、工具連結部を把持部の外周面に被着させることにより工具と工具連結部とが連結されることから、ロープ状部材の一端を直接連結する部分を有しない工具であっても、工具連結部を介してロープを連結することが可能となる。この場合、工具連結部は把持部の径方向に伸縮自在に形成されていることから、工具連結部を径方向に拡大させることによって工具との着脱を容易に行うことができとともに、把持部の外径寸法が異なる他の種類の工具にも使用することが可能である。また、工具連結部は筒状に形成されていることから、工具の把持部を工具連結部の上から違和感なく把持することができる。   Thereby, the tool and the tool connecting portion are connected by inserting the tool holding portion into the cylindrical tool connecting portion to which the rope-like member is connected and attaching the tool connecting portion to the outer peripheral surface of the holding portion. For this reason, even a tool that does not have a portion that directly connects one end of the rope-shaped member can connect the rope via the tool connecting portion. In this case, since the tool connecting portion is formed to be extendable and contractable in the radial direction of the gripping portion, the tool connecting portion can be easily attached to and detached from the tool by expanding the tool connecting portion in the radial direction. It can also be used for other types of tools with different outer diameter dimensions. Further, since the tool connecting portion is formed in a cylindrical shape, the tool gripping portion can be gripped from above the tool connecting portion without a sense of incongruity.

本発明の工具落下防止具によれば、ロープ状部材の一端を直接連結する部分を有しない工具であってもロープを連結することができるので、このような工具の落下を確実に防止することができる。この場合、工具との着脱を容易に行うことができるとともに、把持部の外径寸法が異なる他の種類の工具にも使用することができるので、汎用性が高いという利点がある。また、工具に装着しても工具の把持部を違和感なく把持することができるので、工具の取扱性を損なうことがないという利点もある。   According to the tool fall prevention tool of the present invention, even if the tool does not have a portion that directly connects one end of the rope-like member, the rope can be connected, so that the tool can be reliably prevented from falling. Can do. In this case, since it can be easily attached to and detached from the tool and can be used for other types of tools having different outer diameter dimensions of the gripping portion, there is an advantage that versatility is high. In addition, there is an advantage that the handleability of the tool is not impaired because the gripping portion of the tool can be gripped without a sense of incongruity even when it is mounted on the tool.

図１乃至図５は本発明の一実施形態を示すもので、図１は工具落下防止具を用いて工具を胴ベルトに連結した状態を示す図、図２は工具落下防止具の側面図、図３は図２のＡ−Ａ線矢視方向断面図、図４は工具落下防止具の工具への装着方法を示す側面図、図５はその横断面図である。   1 to 5 show an embodiment of the present invention, FIG. 1 is a view showing a state in which a tool is connected to a body belt using a tool fall prevention tool, FIG. 2 is a side view of the tool fall prevention tool, 3 is a cross-sectional view in the direction of arrows AA in FIG. 2, FIG. 4 is a side view showing a method of mounting the tool drop prevention tool on the tool, and FIG.

本実施形態の工具落下防止具は、工事現場等で使用される工具１に装着され、工具１をロープ２を介して作業者の胴ベルト３に連結するためのものである。   The tool fall prevention tool of the present embodiment is mounted on a tool 1 used at a construction site or the like, and is used for connecting the tool 1 to an operator's trunk belt 3 via a rope 2.

工具１は、例えば周知の結束工具（いわゆるハッカー）であり、鉄筋固定用の結束線を結束するために用いられる。即ち、この工具１は、作業者の把持する棒状の把持部１ａと、把持部１ａの一端に回動自在に取付けられた可動部１ｂとからなり、可動部１ｂの先端に設けた爪状部１ｃを鉄筋に巻き掛けた結束線（図示せず）に係止して可動部２ｂを回転させるように使用される。   The tool 1 is, for example, a well-known binding tool (so-called hacker), and is used for binding a binding wire for reinforcing bars. That is, the tool 1 includes a rod-shaped gripping portion 1a gripped by an operator and a movable portion 1b rotatably attached to one end of the gripping portion 1a, and a claw-shaped portion provided at the tip of the movable portion 1b. The movable part 2b is used by rotating the movable part 2b while being locked to a binding wire (not shown) around the reinforcing bar 1c.

ロープ２は工具連結用に用いられる周知のもので（例えば、従来例参照。）、その両端にはそれぞれ連結用のフック２ａが取付けられている。また、ロープ２の一部は伸縮自在なコイル状に形成されている。   The rope 2 is a well-known rope used for tool connection (for example, see the conventional example), and hooks 2a for connection are respectively attached to both ends thereof. Moreover, a part of the rope 2 is formed in a coil shape that can be expanded and contracted.

胴ベルト３は、例えば工事現場等において作業者が装着する安全帯に用いられるもので、安全帯用のロープ（図示せず）等を連結するためのＤ形のリング３ａが取付けられている。また、胴ベルト３には工具２を収納するためのホルダ３ｂが設けられている。   The body belt 3 is used for a safety belt worn by an operator at a construction site or the like, for example, and a D-shaped ring 3a for connecting a safety belt rope (not shown) or the like is attached. The body belt 3 is provided with a holder 3b for storing the tool 2.

同図に示す工具落下防止具１０は、工具１の把持部１ａに連結される工具連結部１１と、工具連結部１１を工具１の把持部１ａに固定する一対の固定部材１２とを備え、工具連結部１１の一端にはロープ２の一端が連結されるようになっている。   The tool fall prevention tool 10 shown in the figure includes a tool connecting portion 11 connected to the gripping portion 1a of the tool 1, and a pair of fixing members 12 that fix the tool connecting portion 11 to the gripping portion 1a of the tool 1. One end of the rope 2 is connected to one end of the tool connecting portion 11.

工具連結部１１は工具１の把持部１ａの外周面に被着可能な筒状のワイヤネットからなり、ワイヤネットには金属製のワイヤが用いられている。この場合、工具連結部１１はワイヤネットによって径方向に伸縮自在に形成されており、軸方向に収縮すると径方向に拡大し、径方向に拡大させた状態ではワイヤの弾性により径方向に縮小するようになっている。また、工具連結部１１の軸方向一端にはロープ２のフック２ａを連結可能な連結部１１ａが設けられ、連結部１１ａはワイヤネットの一部のワイヤを環状に形成することにより工具連結部１１と一体に設けられている。   The tool connecting portion 11 is formed of a cylindrical wire net that can be attached to the outer peripheral surface of the grip portion 1a of the tool 1, and a metal wire is used for the wire net. In this case, the tool connecting portion 11 is formed to be stretchable in the radial direction by a wire net, and expands in the radial direction when contracted in the axial direction, and contracts in the radial direction due to the elasticity of the wire in the expanded state in the radial direction. It is like that. Moreover, the connection part 11a which can connect the hook 2a of the rope 2 is provided in the axial direction one end of the tool connection part 11, and the connection part 11a forms the wire of a part of wire net in cyclic | annular form, and the tool connection part 11 is formed. And is provided integrally.

各固定部材１２は把持部１ａの周方向に延びるベルト状部材からなり、それぞれ工具連結部１１の軸方向両端に取付けられている。工具連結部１１は把持部１ａの外周面を巻回可能な長さに形成され、その両端部を着脱自在な周知のファスナ１２ａによって結合可能に構成されている。また、固定部材１２は、例えば帯状のゴム紐等、長手方向に弾性を有する部材によって形成されている。   Each fixing member 12 is formed of a belt-like member extending in the circumferential direction of the gripping portion 1 a and is attached to both ends of the tool connecting portion 11 in the axial direction. The tool connecting portion 11 is formed to have a length capable of winding the outer peripheral surface of the gripping portion 1a, and both ends thereof can be coupled by a well-known fastener 12a that is detachable. The fixing member 12 is formed of a member having elasticity in the longitudinal direction, such as a belt-like rubber string.

以上のように構成された工具落下防止具１０を工具１に連結する場合には、図４(a) に示すように工具落下防止具１０の工具連結部１１を軸方向に収縮することにより、図５(a) に示すように工具１の把持部１ａを挿入可能な大きさまで径方向に拡大させ、図４(b) に示すように工具連結部１１を工具１の把持部１ａに挿入した後、工具連結部１１の軸方向の収縮状態を解除する。これにより、工具連結部１１がワイヤネットの復元力により軸方向に伸長して径方向に収縮し、図５(b) に示すように工具１の把持部１ａに被着する。次に、各固定部材１２を工具１の把持部１ａを巻回するようにその両端部をファスナ１２ａで結合することにより、工具連結部１１の両端が各固定部材１２によって工具１に固定される。その際、固定部材１２を長手方向に伸ばしながらファスナ１２ａで結合することにより、固定部材１２がその弾性力によって確実に固定される。   When the tool fall prevention tool 10 configured as described above is connected to the tool 1, the tool connection part 11 of the tool fall prevention tool 10 is contracted in the axial direction as shown in FIG. As shown in FIG. 5 (a), the gripping portion 1a of the tool 1 is enlarged in the radial direction to a size that can be inserted, and the tool connecting portion 11 is inserted into the gripping portion 1a of the tool 1 as shown in FIG. 4 (b). Thereafter, the contracted state of the tool connecting portion 11 in the axial direction is released. As a result, the tool connecting portion 11 extends in the axial direction and contracts in the radial direction by the restoring force of the wire net, and adheres to the gripping portion 1a of the tool 1 as shown in FIG. Next, the both ends of the fixing member 12 are coupled to the tool 1 by the fixing members 12 by joining the both ends of the fixing member 12 with the fasteners 12a so that the gripping portion 1a of the tool 1 is wound. . At that time, by fixing the fixing member 12 with the fastener 12a while extending in the longitudinal direction, the fixing member 12 is reliably fixed by the elastic force.

また、工具落下防止具１０を装着された工具１を使用する場合は、工具落下防止具１０の連結部１１ａにロープ２の一端側のフック２ａを連結し、ロープ２の他端側のフック２ａを胴ベルト３のリング３ａに連結する。これにより、作業者が誤って工具１を落下させた場合でも、工具１がロープ２及び工具落下防止具１０によって作業者に繋ぎ止められることから、例えば高所からの工具１の落下や工具１の紛失を防止することができる。その際、工具落下防止具１０の工具連結部１１にロープ２側から軸方向の引張力が加わると、工具連結部１１が径方向に収縮することから、ロープ２の引張力によって工具連結部１１と工具１との結合力が増大する。   When using the tool 1 with the tool fall prevention tool 10 attached, the hook 2a on one end side of the rope 2 is connected to the connecting portion 11a of the tool fall prevention tool 10 and the hook 2a on the other end side of the rope 2 is connected. Is connected to the ring 3 a of the waist belt 3. As a result, even if the operator accidentally drops the tool 1, the tool 1 is locked to the operator by the rope 2 and the tool drop prevention tool 10, so that, for example, the tool 1 is dropped from a high place or the tool 1 Can be lost. At that time, when an axial tensile force is applied to the tool connecting portion 11 of the tool drop prevention tool 10 from the rope 2 side, the tool connecting portion 11 contracts in the radial direction. The binding force between the tool 1 and the tool 1 increases.

本実施形態の工具落下防止具１０によれば、ロープ２が連結される筒状の工具連結部１１に工具１の把持部１ａを挿入し、工具連結部１１を把持部１ａの外周面に被着させることにより工具１と工具連結部１１とを連結するようにしたので、ロープ２のフック２ａを直接連結する環状部分を有しない工具１であっても工具連結部１１を介してロープ２を連結することができ、工具１の落下を確実に防止することができる。この場合、工具連結部１１は把持部１ａの径方向に伸縮自在に形成されているので、工具連結部１１を径方向に拡大させることによって工具１との着脱を容易に行うことができるとともに、把持部の外径寸法が異なる他の種類の工具にも使用することができるので、汎用性が高いという利点がある。また、工具連結部１１は筒状に形成されているので、工具１の把持部１ａを工具連結部１１の上から違和感なく把持することができ、工具１の取扱性を損なうことがないという利点もある。   According to the tool fall prevention tool 10 of the present embodiment, the gripping portion 1a of the tool 1 is inserted into the cylindrical tool connection portion 11 to which the rope 2 is connected, and the tool connection portion 11 is covered on the outer peripheral surface of the gripping portion 1a. Since the tool 1 and the tool connecting portion 11 are connected by attaching, the rope 2 can be connected via the tool connecting portion 11 even if the tool 1 does not have an annular portion that directly connects the hook 2a of the rope 2. It can connect and can prevent fall of tool 1 reliably. In this case, since the tool connecting portion 11 is formed to be extendable and contractible in the radial direction of the gripping portion 1a, the tool connecting portion 11 can be easily attached to and detached from the tool 1 by enlarging the tool connecting portion 11 in the radial direction. Since it can be used for other types of tools having different outer diameter dimensions of the gripping portion, there is an advantage that versatility is high. Moreover, since the tool connection part 11 is formed in the cylinder shape, the grip part 1a of the tool 1 can be gripped from above the tool connection part 11 without a sense of incongruity, and the handleability of the tool 1 is not impaired. There is also.

また、工具連結部１１を径方向に弾性を有する部材によって形成したので、径方向への収縮力により工具連結部１１を工具１の把持部１ａに確実に被着させることができ、工具連結部１１と工具１とを強固に連結することができる。   Further, since the tool connecting portion 11 is formed by a member having elasticity in the radial direction, the tool connecting portion 11 can be reliably attached to the gripping portion 1a of the tool 1 by the contracting force in the radial direction. 11 and the tool 1 can be firmly connected.

更に、工具連結部１１を筒状のワイヤネットによって形成したので、径方向に伸縮可能な工具連結部１１を簡単な構造により形成することができ、製造コストの低減を図ることができる。この場合、工具連結部１１が網状に形成されることから、把持部１ａの滑り止めになるという利点もある。   Furthermore, since the tool connecting portion 11 is formed of a cylindrical wire net, the tool connecting portion 11 that can expand and contract in the radial direction can be formed with a simple structure, and the manufacturing cost can be reduced. In this case, since the tool connecting portion 11 is formed in a net shape, there is an advantage that the grip portion 1a is prevented from slipping.

また、工具連結部１１の軸方向両端に工具１の把持部１ａに固定可能な固定部材１２を設けたので、工具連結部１１の把持部１ａへの被着のみならず、各固定部材１２によっても工具連結部１１と工具１とを連結することができ、工具連結部１１からの工具１の脱落を確実に防止することができる。   Further, since the fixing members 12 that can be fixed to the gripping portion 1a of the tool 1 are provided at both ends in the axial direction of the tool connecting portion 11, not only the attachment of the tool connecting portion 11 to the gripping portion 1a but also each fixing member 12 Also, the tool connecting portion 11 and the tool 1 can be connected, and the tool 1 can be reliably prevented from falling off from the tool connecting portion 11.

この場合、各固定部材１２を把持部１ａの周方向に延びるベルト状によって形成し、その両端をファスナ１２ａによって互いに着脱自在に形成したので、各固定部材１２の着脱を極めて容易に行うことができる。   In this case, each fixing member 12 is formed in a belt shape extending in the circumferential direction of the gripping portion 1a, and both ends thereof are detachably attached to each other by the fastener 12a, so that each fixing member 12 can be attached and detached very easily. .

また、各固定部材１２を把持部１ａの周方向に弾性を有する部材によって形成したので、各固定部材１２の弾性力によって固定部材１２を工具に確実に固定することができる。   Moreover, since each fixing member 12 is formed of a member having elasticity in the circumferential direction of the gripping portion 1a, the fixing member 12 can be reliably fixed to the tool by the elastic force of each fixing member 12.

尚、前記実施形態では、工具１として鉄筋固定用の結束工具を示したが、工具連結部１１に挿入可能な把持部を有するものであれば、例えはハンマー、ドライバー等、他の工具に用いることができる。   In the above-described embodiment, a bundling tool for fixing a reinforcing bar is shown as the tool 1. However, as long as it has a gripping part that can be inserted into the tool connecting part 11, it is used for other tools such as a hammer and a screwdriver. be able to.

また、前記実施形態では、工具連結部１１に筒状のワイヤネットを用いたものを示したが、径方向に伸縮可能な筒状の部材であれば、例えばゴム製のチューブ等、他の形状または材質の部材を用いることが可能である。この場合、ワイヤネットは化学繊維のワイヤを用いたものであってもよい。   Moreover, in the said embodiment, although the thing using a cylindrical wire net was shown for the tool connection part 11, if it is a cylindrical member which can be expanded-contracted to radial direction, other shapes, such as a rubber tube, will be mentioned, for example. Alternatively, a material member can be used. In this case, the wire net may be one using a chemical fiber wire.

更に、前記実施形態では、ロープ２をフック２ａを介して工具連結部１１の連結部１１ａに連結するようにしたものを示したが、フックを用いずに直接ロープの一端が連結部１１ａに連結されたものであってもよく、或いは工具連結部１１に連結部１１ａを設けずに工具連結部１１の一端にロープが一体に設けられているものであってもよい。   Further, in the above embodiment, the rope 2 is connected to the connecting portion 11a of the tool connecting portion 11 via the hook 2a. However, one end of the rope is directly connected to the connecting portion 11a without using the hook. Alternatively, a rope may be integrally provided at one end of the tool connecting portion 11 without providing the connecting portion 11 a in the tool connecting portion 11.

また、前記実施形態では、固定部材１２としてファスナ１２ａを有するベルト状のものを示したが、他の固定部材として、例えば無端状のゴムリングや粘着テープを用いたものであってもよい。   Moreover, in the said embodiment, although the belt-shaped thing which has the fastener 12a was shown as the fixing member 12, you may use an endless rubber ring and an adhesive tape as another fixing member, for example.
