ABSTRACT:
An amusement swing apparatus for children and adults alike and more particularly, a horizontal rotating manually operated swing. It can be conceptualized as two seesaws lapped in the middle at right angles, but instead of the riders going up and down, they remain in a horizontal plane and rotates about the centre point. Where these beams cross at the middle, they are supported on a housing that carries two bearings, one on top of the housing and one at the bottom. This housing is fitted to a vertical shaft that passes through the centre of the lapped beams and allows the housing with the lapped beams to rotate freely around it. The shaft is firmly fixed to the ground or floor surface. Four or six legs, attached to a flange welded to the shaft add support to the structure. These legs spread out evenly around the flange and are fixed to the ground or floor surface.The four outer ends of the beams have seats for persons to sit on. At the top of the centre shaft is a short vertical pin that is placed offset by a flat plate in the shape of a cam. This cam shaped plate is attached to the top of the centre shaft by means of a boss. The boss is welded to the bottom of the larger side of the cam-shaped plate.Fixed on the underside of each of the lapped beams, at the outer ends near to where each person sits, are footrest frames. Directly above these footrests are handle frames that are hinged to the beams and have a handle for each rider to hold on to with both hands. These handle frames are free to move forward and backwards. Each handle frames have a short cross pin to which the connecting rods are hinged. The other ends of these connecting rods are hinged to the vertical offset pin with interconnecting short knuckle linkages. These short linkages have two rings at each end that are turned horizontal and vertical.Any one out of the four riders can operate the swing. By grabbing the handles and moving them forward and backward creates a translation force on the frame to allow the rider to start rotate around the centre pivotal point.
