Description

[Detailed Description of the Invention] The present invention is an improvement to a safety net for utility poles that is attached to utility poles to prevent workers at heights from falling and to catch falling tools, materials, etc.

Conventionally, this type of safety net has consisted of one pipe or the like for each main pillar. Therefore, even when the net was folded, the length of the main pillar was more than 2 meters, making it inconvenient for storage and transportation. Also, if the utility pole to be installed is close to a building or other obstacle, or if it is necessary to secure a certain height on the road side, the conventional product cannot be installed, and even if it is installed, the net will be half open. It was not used effectively because it was in a state of

The purpose of the present invention is to eliminate and improve the drawbacks of such conventional products.

Aspects of the present invention will now be described in detail with reference to an embodiment illustrated in the accompanying drawings.

As shown in the figure, in this embodiment, two mounting plates 1 and 2 are arranged vertically at a predetermined interval and are connected by a member 17, with a chain holder 3 on one side and a chain holder 3 on the other side. Connect one end of chain 4 to the
A mounting base 6 is provided with a tightening member 5 such as a nut.
A plurality of main pillars 7 are attached to the mounting base 6 so as to be horizontally rotatable, a net 8 is stretched between the main pillars except for one place, and a band 18 is installed between the main pillars on both sides. In safety nets for utility poles, which have a structure in which they are pulled together or have a similar structure,
The proximal main pillar 9 and the distal main pillar 10 in each main pillar 7
It is constructed by telescopically combining these.

The proximal main column 9 constituting the main column 7 is composed of a main column material 12 and a column material 13 with a smaller diameter,
The tip of the strut 13 is fixed near the tip of the main column 12 and connected in a state where it branches toward the base end,
The base end of the strut material 13 is attached to the upper mounting plate 1 of the mounting base 6.
In addition, the base ends of the main pillars 12 are connected to the lower mounting plate 2 so that they can rotate in the horizontal direction, and the distal main pillars 10 are inserted into the main pillars 12 of the proximal main pillars 9. The fixing member 11 is provided on the main pillar member 12, and the main pillar 10 on the distal end side can be adjusted to expand and contract with the pin 19 of the fixing member 11.

To use the present invention, the mounting base 6 is applied to a predetermined position of the utility pole P on which work is to be performed at height, and the chain 4 and the tightening member 5 are used to secure the mounting base 6 in place. Next, each main pillar 7 is rotated in the horizontal direction, and the main pillar 10 on the tip side is rotated in the horizontal direction.
By stretching the net 8, the net 8 is stretched. Thereafter, the band 18 is connected to both the main pillars 7, 7 on the opposite side of the utility pole P so as to pull the two main pillars 7, 7 together, thereby completing the installation.

When attaching to this utility pole P, if there is an obstacle on the net 8 side, or if it faces the road and becomes an obstruction to traffic, move the main pole 10 on the tip side of the main pole 7 in that position as far as necessary. By shortening the length, you can avoid these obstacles when installing.

The present invention is constructed as described above, with each main pillar 7
is divided into the proximal main pillar 9 and the distal main pillar 10, and the distal main pillar 10 is made expandable, so if there is an obstacle on the net installation side, the distal main pillar 10 can be retracted. Therefore, you can avoid this and easily install it. In addition, if it becomes an obstacle to the passage of people or cars on the road side, the safety of both passersby can be ensured by shortening the length of the tip side main column 10 as necessary.

Furthermore, since each main pillar 7 of the present invention is configured to be expandable and retractable, it is convenient for carrying, transporting, storing, attaching and detaching, etc. In addition, in this invention, each main pillar 7 is configured to be expandable and retractable, so the width of the net 8, that is, the catching range, can be freely adjusted depending on the place of use, so it has a wide range of uses and can be used to prevent falling objects. can be safely accepted.

FIG. 4 shows another embodiment of the present invention, in which a proximal main column 9 and a distal main column 10 are connected via a sliding member 14 so as to be extendable and slidable. 14 is a ring 1 fixed near the tip of the proximal main pillar 9;
5, the distal main column 10 is slidably inserted into the distal main column 10, and the proximal main column 9 is slidably inserted into the ring 16 fixed near the proximal end of the distal main column 10. A fixing member 1 that allows 10 to be expanded and contracted and fixed at a predetermined length.
1 is provided on the tip side main column 10 or the sliding member 14, and the other functions and effects are the same.
