[0005]

[Operation] The fixing pin for fixing the slide of the large-diameter pipe of the tension member and the small-diameter pipe fitted to this is removed, and the insertion amount of the small-diameter pipe into the large-diameter pipe is changed to make the small-diameter pipe transparent. By inserting the fixing pin into the hole and the through hole of the large-diameter pipe and fixing the slides of the large-diameter pipe and the small-diameter pipe, the left and right widths of the net attachment frame can be adjusted to the attachment width.

Then, when the operation tube of the tension member is rotated, the pin fixed to the operation tube is moved from the straight portion forming the elongated through hole of the large diameter pipe as the operation tube is rotated. The operation tube moves to the turning portion, and the operation tube slides with respect to the large diameter pipe by the amount of the deviation of the turning portion in the length direction. Further, the through hole of the small-diameter pipe through which the pin fixed to the operation tube penetrates is formed in the shape of a long hole in the direction orthogonal to the axis, so that the operation tube cannot be inserted while the pin penetrates the through hole. Can rotate about the axis as a rotation axis, and when the operation tube rotates with respect to the large diameter pipe, the small diameter pipe slides with the operation tube with respect to the large diameter pipe.

Therefore, after adjusting the left and right widths of the net attachment frame to the attachment width as described above, the operation tube is further rotated to increase the total length of the tension member, so that the elastic member outside the vertical frame is removed. The net attachment frame can be easily removed by firmly pressing and fixing the net attachment frame to the attachment portion, and conversely, shortening the entire length of the tension member by rotating the operation tube.

The protective fence constructed as described above is
It is installed between windows and fences of balconies as follows.

As shown in FIG. 1, when the protective fence is attached to the window, the door 41 on the outdoor side is opened, and as shown in FIG. 5, the operating cylinder 11 of the tension member 20 is fixed to the pin 12 of the large diameter pipe 7a. In a rotated state, that is, by sliding the operation tube 11 outward so that the small diameter pipe 7 ′ is pushed into the large diameter pipe 7a so as to be positioned on the linear portion 15b outside the through hole 14, With the total length of the bracing member 20 shortened, the fixing pin 12 for fixing the slide of the longer large-diameter pipe 7b and the small-diameter pipe 7'fitted thereto is pulled out to remove the large-diameter pipe 7 '. Diameter pipe 7b
The amount of insertion of the net attachment frame 1 is changed so that the space between the vertical frame 43 of the door 42 and the vertical frame 45 of the window frame 44 on the indoor side is changed, and the small diameter pipe 7 ′ is adjusted.
The fixing pin 10 is inserted into the through hole 8 and the through hole 9 of the large diameter pipe 7b to fix the slide of the large diameter pipe 7b and the small diameter pipe 7 '. In this state, the elastic member 16 outside the vertical frame 2 of the net attachment frame 1 hits the vertical frame 45 of the window frame 44 and the vertical frame 43 of the door 42 on the indoor side, and the engaging piece 18 of the metal fitting 6
However, it is caught by the vertical frame 45 of the window frame 44 and the vertical frame 43 of the door 42 on the indoor side.

Next, the operating cylinder 11 of the strut member 20 is gripped and rotated, and as shown in FIG. 6, the pin 12 of the operating cylinder 11 has the linear portion 15 inside the through hole 14 of the large diameter pipe 7a.
