FIELD: entertaining industry. ^ SUBSTANCE: swing has columns, horizontal beam mounted on columns, hangers positioned for axial displacement on horizontal beam, seat and position restricting members, said seat and position restricting members being fixed on hangers. Springs are disposed on hangers between horizontal beam and upper position restricting members, and weights are positioned on upper ends of hangers for rotation relative hangers in swinging plane. Seat is composed of two cross-pieces, four tie-rods and base, which are pivotally connected with one another. Cross-pieces are adapted to be fixed relative to columns and tie-rods. Such construction allows seat of swing to be moved in pendulum motion path, when cross-pieces are fixed relative to tie-rods, and in planar-parallel path, when cross-pieces are fixed relative to columns. ^ EFFECT: simplified construction and wider operational capabilities of swing. ^ 3 dwg |
