DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole safety belt used for electrical work performed at a high place, and more particularly to an auxiliary rope for preventing a non-connected state with a building.

[0002]

2. Description of the Related Art In electrical work at high places,
Wearing the safety belt on the pole, holding the structure with a rope connected to one of the rings located at the waist on both sides, locking the hook at the tip of the rope to the other ring, U-shaped posture between the structure and The work was carried out with the hands held free.
In addition, when moving to a high place before entering this work position, if the hook at the tip of the rope is removed and there is no connection with the structure, there is a danger of falling, so the auxiliary rope connected to the belt first By connecting to the building and removing the hook later, it was possible to prevent the crash by preventing the unconnected state even for a moment. If the auxiliary rope is used properly in this way, the unconnected state will be lost and a crash will not occur, but its use is left to the discretion of the worker, in other words, the safety of the worker It was all about consciousness, an irreplaceable safety measure of uncertainty, due to the mental state of the workers, which varies from day to day and from time to time.

[0003]

Under the circumstances described above, in order to increase the reliability of the use of the auxiliary rope, the auxiliary rope and the main rope (a rope for winding the structure in a U-shape and provided with a main hook at the tip thereof). The problem is solved by adopting an interlock system in which there is an association between the hooks of the rope. Specifically, the safety cap of the hook 6 locked to the ring 2 in a state of being used in a U-shape
The auxiliary hook 9 is locked in the engaging opening 63 provided near the 62 to prevent the rotation of the safety cap 62, thereby controlling the rotation of the opening / closing cap 61 and preventing the opening of the hook. The work is performed in this mode. When the work at the fixed position is completed and it is necessary to move the work, first, the auxiliary hook 9 is detached from the engagement opening 63 provided in the main hook 6. Since the auxiliary hook 9 cannot be locked to the ring of the safety belt or the like, it must be locked to the structure P. The hook 6 from which the auxiliary rope 8 has been removed allows the safety cap 62 to rotate, so that the opening / closing cap 61 also rotates to open the hook and unlock the ring 2. At this time, the auxiliary hook 9 is not locked to the structure P,
Although the hook 6 can be unlocked while the auxiliary rope 8 is hanging from the belt B, the auxiliary hook may be trampled on its own when moving, or the auxiliary hook may be caught on an unexpected object. It is naturally anticipated that it will occur and will naturally lock onto the construction P. When a U-shaped posture is formed at the next construction position at a high place, the auxiliary hook 9 is detached from the structure P and is engaged with the engaging opening 63 of the hook 6 to perform the construction. Can be prevented. Further, in another embodiment, since the auxiliary hook 9 is locked in the engagement opening 63 of the main hook 6, the auxiliary hook 9 once removed from the auxiliary rope locking portion 11 cannot be locked in the locking hole 14 again. In addition, a shutter 15 is provided on the auxiliary rope locking portion 11. Therefore, when the auxiliary hook 9 is detached from the main hook 6 as described above, the auxiliary hook 9 is locked to the structure P, and the unconnected state can be prevented.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment of the present invention, a belt B portion is constituted by a waist belt 3 sewn with rings 1 and 2 at both ends and an outer tightening belt 5 having a buckle 4 at one end. Also, a main hook 6 is attached to one end, and an expansion / contraction adjuster 7 is inserted into an intermediate portion to form a rope R portion. The expansion / contraction controller 7 has a built-in link mechanism, and presses the rope R at a predetermined position by rotation of the link mechanism to fix the position. When working in a U-shaped state, when approaching the structure or when releasing the body, the telescopic adjuster 7 is operated to change the length of the rope R and change the work posture of the user to a position suitable for the work. It is. One of the features of the present application is a ring attached to the belt B portion.
2 Conventionally, the auxiliary rope 8 is attached by using an additional ring on the belt B or by using a D-shaped ring for the hook 6. Is provided. The ring 2 is formed by forging, and has two insertion openings 21 for the outer fastening belt 5, one end connection hole 22 of the auxiliary rope 8, and a main hook engagement hole 23. The hook 6 is formed by forging, has a hook at the tip end, and connects a separate rotating part to the rear end to form a binding portion of the rope R. Since there is a gap between the rotating part and the rotating part at the base end of the auxiliary rope 8, the space is closed and the auxiliary hook 9 is attached to the step bolt of the building P. The engagement prevention ring 10 is provided so that it is easier to lock. The engagement prevention ring 10 is made of a resin or the like, and is attached at the time of rope binding. The opening / closing cap 61 is rotatably fixed on the side of the hook 6 where the hook portion is opened, and near the rotating portion. On the opposite side, the safety cap 62 is fixed on the shaft and brought into contact with the opening / closing cap 61, so that the opening / closing cap 61 cannot be turned unless the safety cap 62 is turned. Before and after, the auxiliary hook 9 used for the auxiliary rope 8 has the configuration described so far, and has almost the same appearance as the main hook 6. A through hole 63 is provided in the vicinity of the safety cap 62 to lock the auxiliary hook 9. When the tip of the hook of the auxiliary hook 9 is located in the engagement opening 63, the safety cap 62
However, even when the rotation of the opening / closing cap 61 starts to rotate, the rotation of the opening / closing cap 61 cannot be performed.

In order to use the above-mentioned safety belt of the present invention, the rope R is wound around the structure P at a high place as shown in FIG. Do the work. At this time, the auxiliary hook 9 of the auxiliary rope 8 is
The hook 6 is prevented from being removed from the locking hole 23 of the ring 2 of the ring 6 in advance. When it is necessary to change the working position, first attach the auxiliary hook 9
6 and lock it to the specified construction P.
Is removed from the locking hole 23 of the ring 2. Therefore, no connection state occurs during this time. Auxiliary hook removed from hook 6
Although there is no guarantee or physical reason to lock 9 to the structure P, it is easier to lock to the structure P such as a step bolt when working on high places, especially on poles, and there is a high probability of doing so. Can be expected. After finishing the work and getting down on the ground, remove the auxiliary hook 9 from the engaging
The hook 6 is removed from 2. FIG. 5 to FIG.
In this embodiment, a small hole that can be locked only by the main hook 6 is provided in the ring 2, and the auxiliary rope 8 is provided with a separate auxiliary rope locking portion 11. The auxiliary rope engaging portion 11 is formed by forging aluminum, and has two insertion openings 12 for the outer tightening belt 5, the base end connecting hole 13 of the auxiliary rope 8, the auxiliary hook engaging hole 14, and the shaft of the shutter 15 for closing the hole. It has a groove 16 for movement. The shutter 15 is formed of a thin plate and slides on both sides of the auxiliary rope locking portion 11 to open and close the locking hole 14. The shutter 15 is always pulled by the spring 17 to close the locking hole 14. Therefore, in order to re-lock the auxiliary hook 9 once removed, it is possible to open the shutter 15 with both hands and lock the auxiliary hook 9 at that time, but the construction P It is easier to lock with the step bolt or the like, and this can be expected with a high probability. When the user descends on the ground after the work, the shutter 15 of the auxiliary rope locking portion 11 is operated with both hands to open a locking hole 14 and lock the auxiliary hook 9.

[0006]

As described above, the use of the auxiliary rope with the auxiliary rope according to the present invention as described above allows the use of the auxiliary rope conventionally entrusted to the will of the worker to be forcibly performed in a half way. Even when you are in an unstable mental state, you can work at heights with confidence.
