この考案は、高所作業用安全帯にフツク付きロ
ープを接続する場合等に用いるフツクに関するも
のである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a hook used when connecting a rope with a hook to a safety belt for working at heights.
一般に、建築工事等の高所で作業を行なう場
合、安全帯を着用し、その安全帯の環体に接続し
たロープの先端のフツクを構造物に掛けて墜落の
防止を図るようにしている。
Generally, when working in high places such as during construction work, workers wear a safety belt and hook the end of a rope connected to the ring of the safety belt to a structure to prevent falls.
上記のような安全帯を使用する場合、ロープに
よつて作業範囲に制約を受けるため、作業位置を
変更するには、ロープ先端のフツクの掛け替えを
必要とし、そのフツクの掛け替えによつて不安定
の状態が生じ、墜落する危険がある。 When using a safety belt like the one above, the work range is restricted by the rope, so changing the work position requires replacing the hook at the end of the rope, which may cause instability. situation may occur, and there is a risk of a fall.
これを防止するため、安全帯の環体に主ロープ
と補助ロープとを接続し、主ロープのフツクを構
造物から取外すとき、補助ロープのフツクを次の
作業位置の構造物にかけて主ロープと補助ロープ
とを交互に使用する方法が採られている。 In order to prevent this, the main rope and the auxiliary rope are connected to the ring of the safety belt, and when the main rope hook is removed from the structure, the auxiliary rope hook is connected to the structure at the next working position and the main rope and the auxiliary rope are connected. A method is adopted in which ropes are used alternately.
上記補助ロープは必要なときにのみ安全帯に接
続するものであるため、普通ロープの端部に安全
帯の環体に対して係合可能なフツクを取付けるよ
うにしている。このようなフツクは、接続状態を
確実に保持し得る安全性の高いものでなければな
らない。 Since the auxiliary rope is connected to the safety belt only when necessary, a hook that can engage with the ring of the safety belt is usually attached to the end of the rope. Such hooks must be highly secure and can reliably maintain the connection.

に保持するようにしている。 As the conventional technology of the above-mentioned hook, for example,
There is one shown in the -7425 publication. As shown in FIGS. 5 and 6, this hook has a pair of support pieces 21 on both side edges of a plate-shaped hook body 20, and a rotatable opening/closing lever 22 supported by the support pieces 21. The tip of the lever is deflected by a spring 23 and engages with the inner surface of the tip of a hook piece 24 provided on the hook body 20. A pin insertion hole 26 is formed in both side walls 25 of the opening/closing lever 22, and the pin insertion hole The opening/closing lever 22 is held in the closed state by the engagement of the split pin 27 inserted in the hook 26 with the upper surface of the hook body 20.
しかし、上記のフツクにおいては、開閉レバー

常に手間がかかるという不都合がある。
However, in the above-mentioned hook, when locking the opening/closing lever 22 in the closed position, it is necessary to insert the split pin 27 into each of the pin insertion holes 26 provided on both side walls 25 of the opening/closing lever 22, and furthermore, it is necessary to insert the split pin 27 into each of the pin insertion holes 26 provided on both side walls 25 of the opening/closing lever 22. Since it is necessary to bend the end of the split pin 27 later, there is an inconvenience that locking the opening/closing lever 22 takes a lot of time and effort.
また、ロツクを解除する場合には、割ピン２７
の端部を矯正して直線状としたのち引き抜く必要

返すため、破損し易いという不都合がある。 Also, when releasing the lock, use the cotter pin 27.
Since it is necessary to straighten the end of the split pin 27 to make it straight and then pull it out, it takes time to unlock it, and the end of the split pin 27 is easily damaged because it is repeatedly bent and straightened. .
そこで、この考案は上記の不都合を解消し、開
閉レバーのロツクおよびロツク解除を容易とする
ことを技術的課題としている。 Therefore, the technical object of this invention is to eliminate the above-mentioned disadvantages and to facilitate locking and unlocking of the opening/closing lever.

As described above, according to this invention, a lock screw that can move forward and backward toward the opening/closing lever is threadedly engaged with the hook body, so that the lock screw can be rotated to bring the tip end of the screw into contact with the opening/closing lever. This makes it possible to prevent the opening/closing lever from rotating, thereby reliably locking the opening/closing lever in the closed position. Further, by moving the tip end of the lock screw away from the opening/closing lever, the opening/closing lever becomes rotatable, and the locking of the opening/closing lever can be released. Therefore, according to this invention, it is extremely easy to lock and unlock the opening/closing lever.
