Description

[Detailed Description of the Invention] The present invention relates to a device for fixing a ladder so that it does not come off when leaning against a telephone pole for telephone work or the like.

Ladders are used to climb utility poles when doing telephone work or power transmission/distribution line work, but in the past, people used to lean a regular ladder against the utility pole, climb the ladder, and secure the top of the ladder to the pole with a rope, etc. Because of this, when climbing the ladder or descending it after construction work, the ladder was not secured, making it unstable and dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device that can fix the upper part of a ladder to a utility pole from the ground by solving the problems of the conventional ladder fixing method.

In this invention, the upper end of a fixed rope is fixed to the top of the ladder, and a movable rope insertion ring is attached to the top of the ladder, and this ring is provided with at least one ring through which the fixed rope can be passed. This relates to a ladder fixing device characterized in that the ladder is movably inserted through the ladder.

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 shows the configuration of a ladder according to the present invention, in which the upper end of a fixed rope 2 is fixed to the upper part of a ladder body 1, and the other end is free. Further, a ring 3 is provided at the upper part of the ladder main body 1, and an endless movable rope 4 is inserted through the ring 3 so that it can freely pass therethrough. A ring 5 is provided in the middle of the movable rope 4, and the fixed rope 2 can be passed through the ring 5. This ring 5 may be provided at a plurality of locations on the movable rope 4.

Next, a method of fixing the ladder having the above configuration will be explained. First, with the fixed rope 2 and movable rope 4 separated, lean the ladder body 1 against the utility pole P, align the fixed rope 2 and movable rope 4 on the back side of the utility pole P on the ground, and pull one side of the movable rope 4. Stretch it so that the ring 5 is at the bottom, pass the lower end of the fixed rope 2 through the ring 5, and pull one side of the movable rope 4 so that the ring 5 moves upward while pulling the fixed rope 2 to some extent. Move the rope so that the ring 5 reaches the ring 3 at the top of the ladder. In this state, tie the fixed rope 2 and the movable rope 4 to the utility pole P so that they do not loosen. If necessary, tie the excess rope to the ladder body 1. (See Figure 2).

In this way, the ladder can be fixed to the utility pole while working on the ground. When the work is finished, go down the ladder, unfasten each rope on the ground, pull the movable rope 4 so that the loop 5 of the movable rope 4 is at the bottom, and remove the free end of the fixed rope 2 from the loop 5. The rope becomes open and the ladder can be removed from the utility pole P.

As mentioned above, according to the present invention, it is possible to fix and remove a ladder on the ground with a simple structure, and the instability that is conventional when climbing and descending a ladder is eliminated, and This has the effect of preventing accidents such as falls and allowing safe work.
