Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a beryllium copper alloy, which is used since sparks fly in metallic fixtures in the case of collision, is not more extended than iron, not deformed even when a impact load is imposed by falling, and is used as it is after fall since a connection belt hardly has a fall trace at a glance though one fall gives a little twist in some cases, so as to break a ring after several times of falling and not to perform holding. <P>SOLUTION: One side of the connection belt 6 is connected to the ring 5 which is arranged in the intersection part of a back part shoulder belt 1 and the other side is arranged in a breast part, so as to mount the connection belt 6. A fall display part is arranged in the connection belt 6 and the several times of usage is prevented. Specifically, the middle part of the connection belt 6 is folded to have a superimposition part 63. A tension member 7 is disposed along the superimposition part 63. In the case of falling, the tension member 7 is cut so as to open the superimposition part 63. Thus, falling is confirmed in the display part 8. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本願は、高所作業者が墜落防止のために身体に装着する防爆型フルハーネス安全帯に関するものである。   The present application relates to an explosion-proof full harness safety belt that is worn on a body by an altitude worker to prevent a crash.

従来の防爆型フルハーネス安全帯は、特願２００２−２６４５９８に開示したものがある。
これは、爆発の危険性があるガソリン給油所等で、作業者の墜落，転落を防止するために設けられた安全装置の一部として、導電繊維を織込んだベルトを用いて製作したフルハーネス安全帯があり、作業者に帯電する静電気のスパークによって起る、爆発事故を防止すると共に、作業者の高所からの墜転落事故を防止する目的で使用されるものである。
なお、この防爆型フルハーネス安全帯は、金具類を銅・銅合金製として、金具類の衝突による火花の発生を防止したことが開示されている。
特願２００２−２６４５９８ A conventional explosion-proof full harness safety belt is disclosed in Japanese Patent Application No. 2002-264598.
This is a full harness manufactured using a belt woven with conductive fibers as part of a safety device provided to prevent workers from falling or falling at a gasoline filling station where there is a risk of explosion. There is a safety belt, and it is used for the purpose of preventing explosion accidents caused by static sparks charged to the worker, and preventing accidental falls from the height of the worker.
This explosion-proof full harness safety belt is disclosed that the metal fittings are made of copper / copper alloy to prevent the occurrence of a spark due to the collision of the metal fittings.
Japanese Patent Application No. 2002-264598

防爆型フルハーネス安全帯の金具類は、接触によって起こる火花を防止するため、特許文献１で開示したものは、銅製と表記されているが、銅・銅合金（真鍮）・ベリリウム銅合金等の材料を使用しており、本リングには、ベリリウム銅合金を用いたものであり、鉄とは違い伸びがなく、１度落下しても形跡が残らず、何回か落下使用すれば、一挙に金具が破断し、引き止めることが出来ない状況になることが考えられるものであった。   In order to prevent sparks caused by contact with the metal fittings of the explosion-proof full harness safety belt, the one disclosed in Patent Document 1 is written as copper, but copper, copper alloy (brass), beryllium copper alloy, etc. This ring is made of beryllium copper alloy, and unlike iron, it does not stretch and no trace remains even if it drops once. However, it was thought that the metal fitting was broken and could not be stopped.

よって、本願は、背部交差部に設けた本リングより、正面胸部へ連結された連結ベルトに落下表示部を設けるものである。
具体的には、連結ベルト６の中間部を折り畳んで重合部63を設けると共に、該重合部63に添ってテンション部材７を設け、該テンション部材７の両端部を連結ベルト６に連結し、落下時において連結ベルト６に衝撃荷重が加わることにより、テンション部材７が切断して重合部63が開き、落下したことが確認でき、再使用を防止するものである。 Therefore, this application provides a fall display part in the connection belt connected with the front chest rather than the main ring provided in the back crossing part.
Specifically, the overlapping portion 63 is provided by folding the intermediate portion of the connecting belt 6, the tension member 7 is provided along the overlapping portion 63, both ends of the tension member 7 are connected to the connecting belt 6, and the drop When the impact load is applied to the connecting belt 6 at that time, it can be confirmed that the tension member 7 is cut and the overlapping portion 63 is opened and dropped, thereby preventing reuse.

以上のように、本願の防爆型フルハーネス安全帯は、連結ベルト６に落下表示部８を設けたことにより、落下したならば表示部のテンション部材７が切断して重合部63が開き、容易に判別できるため、引き続いての使用は無くなる。   As described above, the explosion-proof full harness safety belt of the present application is provided with the drop display portion 8 on the connecting belt 6 so that if it falls, the tension member 7 of the display portion is cut and the superposition portion 63 is opened. Therefore, subsequent use is eliminated.

本願の実施例を詳記すると、
導電性繊維を織り込んだベルトにより、背部において交差させ両肩に掛ける肩掛けベルト１と、足を挿入する一対の環状の腿掛けベルト２とを一体に形成し、背部の交差部分にベリリウム銅合金の本リング５を設け、該本リング５に導電性繊維を織り込んだベルトから成る連結ベルト６の一方を連結し、他方に輪状部61を設け、該輪状部61を肩掛けベルト１の胸側に配置し、面ファスナー62で肩掛けベルト１に仮固定する構造の防爆型フルハーネス安全帯において、連結ベルト６の中間部を折り畳んで重合部63を設けると共に、該重合部63に添ってテンション部材７を設け、該テンション部材７の両端部を連結ベルト６に連結し、落下時に高衝撃荷重が連結ベルト６に加わることにより、テンション部材７が切断して重合部63が開き、落下したことが確認できる落下表示部を有したものである。
なお、落下表示部は、熱収縮チューブ64により被覆したものである。 Detailed examples of the present application:
By means of a belt woven with conductive fibers, a shoulder belt 1 that crosses at the back and hangs on both shoulders and a pair of annular thigh belts 2 into which legs are inserted are integrally formed, and a beryllium copper alloy is formed at the crossing portion of the back. The main ring 5 is provided, one of the connecting belts 6 made of a belt woven with conductive fibers is connected to the main ring 5, and the ring-shaped portion 61 is provided on the other side, and the ring-shaped portion 61 is disposed on the chest side of the shoulder belt 1. In the explosion-proof full harness safety belt having a structure that is temporarily fixed to the shoulder belt 1 with the hook-and-loop fastener 62, the overlapping portion 63 is provided by folding the intermediate portion of the connecting belt 6 and the tension member 7 is attached along the overlapping portion 63. Provided, both ends of the tension member 7 are connected to the connecting belt 6, and a high impact load is applied to the connecting belt 6 at the time of dropping, whereby the tension member 7 is cut and the overlapping portion 63 is opened and dropped. There are those having a dropping display unit can be confirmed.
The drop display portion is covered with a heat shrinkable tube 64.

テンション部材７として、合成繊維製ベルト・合成樹脂材・アルミ材を用いて、通常作業者が引っ張る荷重（〜２００Ｋｇｆ）では切断しないように、幅・厚みを設定し、連結ベルト６裏面に連結するものである。   Using a synthetic fiber belt, a synthetic resin material, and an aluminum material as the tension member 7, the width and thickness are set so as not to be cut by a load (up to 200 kgf) that is normally pulled by an operator, and the belt is connected to the back surface of the connecting belt 6. Is.

また、落下表示部８として、連結ベルト６の中間部を折り畳んで重合している重合部63を縫着し、落下衝撃荷重が加われば縫着糸が切断し、重合部63が開き、再使用を防止することも可能である。   Further, as the drop indicator 8, the overlapped portion 63, which is formed by folding the intermediate portion of the connecting belt 6, is sewed, and when a drop impact load is applied, the sewing thread is cut and the overlapped portion 63 is opened and reused. It is also possible to prevent this.

本願を装着するには、先ず、肩掛けベルト１を肩に掛ける。続いて、胸ベルト11の樹脂製バックルを嵌合し、肩より外れないようにする。そして腿掛けベルト２を股の間より前側に持ってくる。そして、先端に設けたパススルーバックルの雄金具22を肩掛けベルト１のパススルーバックルの雌金具12へ挿通嵌合し、ベルト端部を引き身体に合った長さに張設する。
以上で装着完了である。
外す時は、パススルーバックルの雄金具22を持って引き上げることによってベルトにゆとりができ容易に外すことができる。 In order to wear the present application, first, the shoulder belt 1 is hung on the shoulder. Subsequently, a resin buckle of the chest belt 11 is fitted so that it does not come off the shoulder. Then, the thigh belt 2 is brought in front of the crotch. Then, the male fitting 22 of the pass-through buckle provided at the tip is inserted and fitted into the female fitting 12 of the pass-through buckle of the shoulder belt 1, and the belt end is pulled and stretched to a length suitable for the body.
The installation is complete.
When removing, the belt can be removed easily by holding the male fitting 22 of the pass-through buckle and pulling it up.
