Abstract:
1. An amusement swing apparatus assembly for rotating its riders in a horizontal plane, comprising of: a vertically extending cylindrical main centre post with an upper end and a lower end, having said lower end fixed to a flat base plate which is anchored to a floor surface; a stabilizing flange welded onto said main post at a predetermined position substantially between mid-point thereabout and said lower end and is disposed generally horizontal and parallel to said floor surface thereof, said flange mounted substantially coaxially to said main post and having at least four equally spaced bolt holes on a predetermined bolt hole circle thereon; a stationary crank fixedly mounted to the upper end of said main post and essentially made up of a crank arm that is substantially horizontal to said floor surface and a vertical crank pin whose axis is offset from the axis of said main post; four stabilizing legs with upper ends and lower ends, having said upper ends attached to said stabilizing flange of said main post while said lower ends are anchored to said floor surface thereof, said legs extends radially outwardly from said stabilizing flange; two perpendicularly lapped beams which are coplanar and having an upper side and an underside, said beams forming a junction where they intersect, said junction having a shaped flat plate used for reinforcement mounted on said upper side of said lapped beams, said junction having a hole therethrough at a centre thereof passing through said junction and said flat reinforcement plate, bore of said hole is substantially larger than the outside diameter of said main post with said main post passing centrally therethrough, said lapped beams thus having four radially extending free ends thereof; a centre support structure having an upper end and a lower end; four obliquely mounted braces with upper ends and lower ends, having said upper ends fixed to the underside of said extending ends of the lapped beams while said lower ends are secured to the lower end of said centre support structure; four bucket seats for riders to sit on, facing inward towards the main post and mounted on said lapped beams at said extending ends thereof; actuator means which comprises of four handle frames, four connecting rods and four knuckle linkages, said handle frames having top and bottom ends, said bottom ends are hinged onto the extending ends of said lapped beams, substantially in front of said seats, said connecting rods having upper ends and lower ends, said upper ends connected to said top ends of said handle frames, said knuckle linkages having first and second ends, said first ends hinged to said lower end of said connecting rods while the second ends are connected to said vertical crank pin; one upper and one lower flanged mounted type ball bearings having inner and outer rings, said inner rings have at least two setscrews while the outer rings are fixed to the flanges thereof, said flanges have at least two equally spaced bolt holes; four footrests fixed to and depending substantially vertically downwards from said extending ends of the lapped beams at a predetermined position thereabout front of said seats; anchoring means which comprises of spike nails for mounting the swing outdoor in a lawn, rawlbolts for mounting onto a concrete floor or coach screws to mount onto a wooden floor surface; whereupon rotating motion is initiated and propagated by translation of forces imparted by the pulling and pushing on the handles by the riders.
