Description

本願は、高所作業者が墜落防止のため、身体に装着する安全帯に設けられた命綱先端に連結されるフックとの摩耗防止シンブルに関するものである。 The present application relates to a wear prevention thimble with a hook connected to a lifeline tip provided in a safety belt to be worn on a body for an altitude worker to prevent falling.

以前より、墜落防止のために安全帯を装着して、高所作業を行っており、その安全帯には、三つ打ちロープ・八つ打ちロープ又、細幅織りのベルトを巻取機に巻き取る方式の命綱が連結されており、命綱先端部に設けられた係止フックを構造物に係止し、高所よりの墜落を防止している。 In the past, safety belts have been installed to prevent falling, and work has been carried out at high places. For these safety belts, three-strand ropes, eight-strand ropes, and narrow belts are used as winders. A lifeline of a winding system is connected, and a locking hook provided at the tip of the lifeline is locked to the structure to prevent a fall from a high place.

図７、８のように、従来のベルト状命綱の端末部は、袋織ベルト７を挿入して、フックＨとの摩耗防止を図っている。
しかしながら、組立上フックＨの連結穴にベルト先端部を挿通してから折り返し部分を縫着するので、縫着時フックが邪魔になって作業性の悪いものであった。
また、縫着部分には、熱収縮チューブ５を被せて、縫着部の縫糸の保護を行っており、この熱収縮作業時にもフックＨが邪魔で作業性の悪いものであった。
さらに、ベルト状命綱Ｂと袋織ベルト７の段差が大きく熱収縮チューブ５によって、保護しても凸凹した形状となり、見栄えの悪いものであった。また、その凸凹部が構造物等に当たって熱収縮チューブ５が破損することもあった。 As shown in FIGS. 7 and 8, the end portion of the conventional belt-like lifeline is designed to prevent wear with the hook H by inserting the bag woven belt 7.
However, since the folded portion is sewn after inserting the belt front end portion into the connecting hole of the hook H for assembly, the hook becomes in the way of sewing and the workability is poor.
Further, the heat-shrinkable tube 5 is put on the sewn portion to protect the thread of the sewn portion. Even during this heat-shrinking operation, the hook H is obstructive and the workability is poor.
Further, the step difference between the belt-shaped lifeline B and the bag-woven belt 7 is large, and even if it is protected by the heat-shrinkable tube 5, it becomes an uneven shape, and the appearance is poor. Further, the heat-shrinkable tube 5 may be damaged when the convex and concave portions hit a structure or the like.

従来のものとしては、意匠登録第１１１１０５５号のものがある。
これは、安全帯命綱の端末部に挿通する合成樹脂製のベルトの保護シンブルであり、組立上フックの連結穴に保護シンブルを挿通してから折り返し部分を縫着するもので、従来のものと同じく、加工時にフックが付いており作業性の悪いものである。
意匠登録第１１１１０５５号 As a conventional one, there is a design registration No. 1111055.
This is a protective thimble of a synthetic resin belt that is inserted into the end of the safety band, and after the protective thimble is inserted into the connecting hole of the hook for assembly, the folded portion is sewn. Similarly, hooks are attached at the time of processing, and workability is poor.
Design registration No. 1111055

本願は、墜落防止用安全帯のベルト状命綱の端部処理を簡単に行うことを目的に発明されたものである。 The present application was invented for the purpose of easily performing the end processing of the belt-shaped lifeline of the safety belt for preventing crash.

本願は、樹脂製シンブルを雌部材１・雄部材２の２分割とし、命綱の端部縫製加工を行った後、端部輪状部に嵌合するものである。
具体的には、内部に貫通穴と、該穴に結合する凹部を設けた鍵穴状の穴を設けた略カム形状の内筒と、該内筒の外側に開放部を設けた外壁を設け、内筒と外壁間にベルト嵌入部を設けた雌部材と、
前記凹部に対応する凸部を設けた貫通穴に嵌入する内筒と、該内筒の外側に開放部を設けた外壁を設け、内筒と外壁間にベルト嵌入部を設けた雄部材とから成る構造のものである。 In the present application, the resin thimble is divided into two parts, a female member 1 and a male member 2, and after the end of the lifeline is sewn, the resin thimble is fitted to the end ring-shaped portion.
Specifically, a substantially cam-shaped inner cylinder provided with a through hole and a keyhole-shaped hole provided with a recess coupled to the hole, and an outer wall provided with an open portion outside the inner cylinder, A female member provided with a belt insertion portion between the inner cylinder and the outer wall;
From an inner cylinder that fits into a through-hole provided with a convex portion corresponding to the concave portion, an outer wall that provides an open portion on the outside of the inner cylinder, and a male member that provides a belt insertion portion between the inner cylinder and the outer wall Of the structure

以上のように、ベルト状命綱の端末部に、分割した樹脂製シンブルを後組みすることによって、ベルト端部の縫着・熱収縮チューブの加工性が格段に向上すると共に、フックの在庫が無くても命綱の加工ができる。
また、組み上がっているものでも、リベットを外せばフックの取替えが可能であり、フックの異なる型番にも注文数に素早く対応することができ、在庫管理もし易くなった。 As mentioned above, by post-assembling the divided resin thimbles at the end of the belt-shaped lifeline, the workability of the belt end sewn and heat-shrinkable tube is greatly improved, and there is no stock of hooks Even a lifeline can be processed.
In addition, even if it is assembled, it is possible to replace the hook by removing the rivet, and it is possible to quickly respond to the number of orders for different model numbers of the hook, and it is easy to manage inventory.
