The safety nettings of the sliding bellows-type are manufactured from iron bars of various cross-sections. They are transversally interconnected by means of rivets to form a uniform netting which is confined by beams (8,9) wherein said netting folds and slides on the slide bars (4); the component parts of the invention secure with a lock and are made to mate the door and window opening. When the opening is up to 120 cm high, the binding of the netting E with the beams (8,9) is effected with the rivets (10) at the lower ends, whereas the other ends are joined to the sliders (4). In the case where the height of the opening exceeds over 120 cm, the folding netting should be composed of two component parts (E,F) connected at the centre with the beams (8,9) by means of rivets, whereas the other ends are connected with the sliders (4). The tops (I,Z) of the components are connected with the guides (17) whose extremities are steadily resting on the beams. The connection is effected with the special joints (18). In case where the opening exceeds over 250 cm, the folding netting should be composed of a plurality of components connected at the centre with vertical rods (20). The invented foldable sliding netting occupies no room to leave the entrance free. |
