(Operation) The operation of the handle operation assisting device H shown in the present embodiment will be described with reference to FIGS. 1 to 3. The handle operation assisting device H is attached so that the roller 212 is located at substantially the same height as the handle 80 in the telephone pole D provided with the switch 8. The operation ropes 90 and 91 are introduced from the lower side of the handle operation assisting device H through the gap between the roller 212 and the bearing member 210, and further, while being placed on the roller 212, drawn out through the gap between the roller 212 and the guard portion 214. It is attached by connecting to the end of the handle 80.

In the normal state, the handle 80 of the switch 8 has the display needle 81 "automatic" as shown by the solid line in FIGS.
It points to the direction of. Roller 21 in this state
2 is located at the inner end of the shaft 211, and the operation ropes 90 and 91 are in a state where they are not substantially in contact with the guide wall 213.

An operation for switching the direction pointed by the display needle 81 of the handle 80 from "automatic" to "manual insertion" will be described. The operation rope 90 in the hung state is pulled downward (vertical direction). In the operation rope 90, the roller 212 is provided at a position substantially at the same height as the handle 80 and is placed on the roller 212, so that the pulling direction is changed from the vertical direction to the horizontal direction. This causes the handle 80 to rotate in the horizontal direction.

Since the center portion of the handle 80 is the center of rotation, the operation rope attachment portion 800, to which the operation ropes 90 and 91 are attached, moves outward by the rotation (imaginary line shown in FIG. 3). As the operation rope 90 moves to the outside in this way, a force pushing outwardly acts on the guide wall 213 outside the roller 212, and the roller 212 slides on the shaft 211 and moves to the outside. At this time, the operation rope 90 has a direction perpendicular to the length direction of the shaft 211 because the shaft 211 is provided in correspondence with the width of change in the position of the operation rope 90 due to the rotation of the handle 80. ing.

When the handle 80 is in the position shown by the phantom line in FIG. 3, the roller 212 is located at the outer end of the shaft 211, and the operating rope 90 substantially contacts the guide wall 213. It has not been done.

Further, by pulling the operation rope 90, the handle 80 is rotated. In this way, the display needle 81 is switched to indicate "manual entry" (imaginary line shown in FIG. 3). At this time, the operation rope attachment portion 800 to which the operation ropes 90 and 91 are attached moves again inward.
When the operation rope 90 moves inward in this way, a force pushing inwardly acts on the guide wall 213 inside the roller 212, and the roller 212 moves inward. At this time as well, the operation rope 90 has a direction perpendicular to the length direction of the shaft 211. Then, the roller 212 returns to the original position before the handle 80 was rotated. With the above, the switching of the handle 80 is completed.

When the operation rope 90 is pulled to rotate the handle 80, if the required tension is also applied to the operation rope 91 and the operation rope 91 is in a tensioned state, the operation rope 91 and the operation rope 91 are mounted. Roller 212
Also moves in the same manner as the operation rope 90 and the roller 212 on which the operation rope 90 is placed. In addition, the operation rope 90 and the operation rope 91 in this case are substantially parallel to each other although the distance changes.

Further, when the direction pointed by the display needle 81 of the handle 80 is switched from "manual insertion" to "automatic", the operation rope 91 may be pulled downward. By pulling the operation rope 91, the handle 80 rotates in the opposite direction to the above case. The operation when the operation rope 91 is pulled is the same as when the operation rope 90 is pulled, and therefore the description thereof is omitted.

By using the handle operation assisting device H as described above, the handle of the switch 8 having the handle 80 that rotates in the horizontal direction can be easily operated from the ground or the like by the operation rope. In other words, the worker does not have to go up the utility pole D or get on the lift, and the labor for operating the handle 80 can be reduced. Therefore, for example, even when an emergency is required, it is possible to respond promptly.

When the handle 80 rotates and the operation rope attachment portion 800 of the operation ropes 90 and 91 moves outward or inward, the roller 212 moves the operation rope 9 to the operation rope 9.
Since the operation ropes 90 and 91 always have a direction at a right angle to the length direction of the shaft 211, the movement of the operation ropes 90 and 91 follows. Release the extra force generated by
The frictional force applied to the operation ropes 90 and 91 and the roller 212 can be reduced. As a result, the operation ropes 90 and 91 are
With no extra load, the roller 212 can be pulled with a lighter force than that which does not move.

In the present embodiment, the steering wheel operation assisting device H
Was used for the switch 8 attached to the electric pole D, but the present invention is not limited to this and can also be used for a switch provided at a place other than the electric pole.

The terms and expressions used in the present specification are for the purpose of description only, and are not limiting in any way, and the terms and expressions equivalent to some of the features described in the present specification and some of them are used. There is no intent to exclude the expression. Needless to say, various modifications are possible within the scope of the technical idea of the present invention.
