０とが展開していく。 If the tightening screw 15 is adjusted so that the locking force exerted by the weight 26 of the descent prevention mechanism 21 is greater than the sliding resistance of the wire holding mechanism 12 against the wire E, the descent of the net hanging frame 11 can be prevented. Then, only gondola B descends. Then, as gondola B descends, net A's distance control cable 2
0 develops.

る。 That is, as shown in FIG. 3, with the distance regulating rope 20 holding the net suspension frame 11 and the gondola B at a predetermined distance, the net suspension frame 11 descends together with the wire E, and the weight arm 24 rotates counterclockwise around the first shaft 23. As a result, the lock piece 28 comes off the frame tongue 17, and the weight arm 24 rotates clockwise due to the weight of the weight 26, returning to its original position (imaginary line in FIG. 3). As a result, the net hanging body 11 is
When net A is fully expanded, work can be carried out by raising and lowering it together with gondola B using wire E.
次に、作業終了後、ゴンドラＢを最上位置まで

When the frame tongue 17 comes into contact with the lock piece 28, it easily pushes up the lock piece 28 around the second shaft 27 and rotates it counterclockwise (FIG. 4), allowing it to pass through the lowering prevention mechanism 21. do. After the lock piece 28 passes through the
It is restored by its own weight (or spring).
その後、ネツト吊下枠１１は、上昇阻止板３１
に当接して上昇が阻止される。 After that, the net suspension frame 11 is moved by the rise prevention plate 31.
It touches and is prevented from rising.

内側に自然に収納される。 When wire E is further wound up, net suspension frame 1
The wire holding mechanism 12 of 1 slides and connects to the net A.
The distance regulating cable 20 is folded and naturally stored inside the net receiver 19.
これにより、全体の高さが第１図のようにちぢ
められた状態にもどる。 As a result, the overall height returns to the reduced state as shown in FIG.

実に防止できる。 As described above, according to the embodiment of the present invention, the net is simply suspended from the net suspension frame provided on the cable without using conventional pillars or frameworks, which simplifies the structure and , will not obstruct the traffic of people or vehicles passing on the ground. In addition, the net can be stretched as long as necessary for the construction work, and scattering pollution can be reliably prevented.
さらに、ネツトを自動的に折畳めるので、あら

また、養生ネツトが丈夫な場合には、この養生
ネツトに距離規制手段を兼用させれば、前記実施
例で示したような距離規制索２０は不要となる。 Further, if the curing net is strong and the curing net also serves as the distance regulating means, the distance regulating cable 20 as shown in the above embodiment becomes unnecessary.
