FIELD: physics.
SUBSTANCE: proposed device consists of a set of metal wires 2 assembled in bundle that makes a fan with maximum opening D. Wires 1 are fitted into hole 2 of stepped rod 3 with its threaded end 4 jointed, by nut 5 and washer 6, to crosspiece 7 of line support. Ends of wire 1 are bent at an angle to their lengthwise axes 8. Sleeves 9, 10 are attached perpendicular to stepped rod 3. Said sleeves accommodate flexible steel rope 11 secured in symmetry about vertical axis 12 of stepped rod 3. In compliance with second version, rods 20, 21 with 6-14 mm-dia are welded to rod and furnished with constricting washers 22, 23. Tube 25 with ID larger than diametre of rods 20, 21 is fitted thereon. To constrict travel of tube 25 along lengthwise axis 26 of rods 20, 21, nuts 27 with washers 28 are screwed thereon.
EFFECT: simplified design, reduced material input, expanded performances.
