FIELD: mass entertainment equipment, in particular, jumping device. SUBSTANCE: device has base 1 made in the form of T-shaped dismountable assembled frame with two mutually perpendicular beams, inclined sectioned mast 2 with rigid guides, truck 3 with rollers. Mast 2 and brace 4 are pivotally secured in eyelets on opposite ends of supporting frame. Supporting frame is made from two separate sections interconnected along flanged joint. Hoisting winch 5 is mounted adjacent to flanged joint. Pivot joints of mast 2 are positioned on lower part of transverse beam. Brace 4 has separate pivotally interconnected links, with terminating link being fixed on upper belt of mast 2, which has triangular cross-section. Cabin 6 is fixed on truck 3 and is movable on lower mast belts. Side tension members impart side stability to mast and prevent it from falling toward main brace. EFFECT: wider operational capabilities, transportability and increased entertainment effect. |
