<p>Dual path moving walkway of the type where pallets of treadplates circulate about the terminal ends has a swivel joint connecting the inner sides to enable the pallets to move in a horizontal plane or up an incline. The swivel joint consists of overlapping links mounted at the trailing edge of one pallet and the leading edge of the adjacent pallet and interconnected by vertical pivot pin which carries a ring located in an aperture in one of the links. The outer surface of the ring and the corresponding wall of the aperture are spherical to permit relative movement in a vertical plane between the ring and the link. Consequently, the adjacent pallets can pivot relative to each other in a horizontal plane and in a vertical plane.</p> |
