Description

[Detailed description of the invention] This invention is mainly used for power transmission and distribution and other high-altitude work by inserting it into the safety belt worn by workers or for fall prevention, and suspending the tools necessary for the work. This is an idea related to a hook for the purpose.

Conventionally, this kind of equipment involved hooking a large hook to a ring attached to the safety belt worn by the worker, or attaching a hook-shaped hook made of wire or the like to an arbitrary position on the safety belt. .

In the former case, when wearing a safety belt with a large hook attached to it, the weight of the safety belt itself becomes heavy, and if tools are hung from the hook, the hook and tools may be damaged depending on the worker's working posture. Each of the hooks would stick out, giving the worker a sense of intimidation, and in some cases there was a danger that tools could come off from the hooks of the hooks. In the latter case, if large tools were hung, the hooks would stretch, so only certain tools or lightweight items could be hung.

The proposed hook has a hook 1 on one side and a small hook 2 whose base end is folded back on the other side, a screw 3 is carved into the small hook 2, and a nut 4 is screwed into it. A hook opening/closing rod 7, which is biased in the closing direction by a spring 6, is rotatably attached to the tip of the small hook 2, and the opening/closing rod 7 can be made rotatable or non-rotatable by means of a nut 4. It has a structure in which the back part of the hook 8 is joined to a belt holder 10 having a belt insertion part 9 formed by folding back both ends of the hook 8.

The hook 8 and the belt gripping body 10 may be fixed directly as shown in FIG. 4, or may be coupled via a hinge 5 as shown in FIGS. 2 and 3 so as to be rotatable.

To use the tool hanging hook of the present invention, first, the belt S is inserted through the belt insertion portion 9 of the belt holder 10, and is attached to the safety belt worn by the worker on his or her waist.

In this state, if the nut 4 is rotated and moved in the direction of arrow A, and the nut 4 releases the pressure on the head of the opening/closing rod 7, the opening/closing rod 7 becomes freely rotatable. Thereafter, tools or construction materials are hung from the hook 1 of the hook 8.

After that, if the nut 4 is rotated and moved in the direction of arrow B and the head of the opening/closing rod 7 is pressed with the nut 4, the rotation of the opening/closing rod 7 will be locked, so tools etc. suspended from the hook 1 will not come off. There is no.

In addition, in the embodiment in which the hook 8 and the belt gripper 10 are connected via the hinge 5, since the hook 8 is rotatable relative to the belt gripper 10, the tools suspended from the hook 8 are also rotated accordingly. Since it moves, it does not give a feeling of intimidation to the worker in any working position.

In addition, when moving the work place in a high place such as a steel tower, if there is an obstacle on the way, if the tool hanging hook of the present invention is configured to be rotatable, it will be possible to avoid the obstacle and avoid the obstacle. There is no danger of workers accidentally falling due to them.

In addition, in the present invention, the safety device that prevents rotation of the opening/closing rod 7 is activated by the movement of the nut 4.
Since the head of the hook is pressed down, there is no play during operation, making it reliable and safe.
Tools, etc. suspended from the floor will not come off and fall inadvertently.

In addition, although the hook 8 of the present invention is designed to be lightweight and compact, the hook 1, which is actually required, is greatly curved, so that a large number of tools can be reliably hooked there. It can be attached to a safety belt simply by inserting the belt S through the insertion part 9, and the structure is extremely simple, so it has remarkable effects such as being able to be provided at low cost and in large quantities.
