  • Patent number: 4981387
    Abstract: A connector for tubular poles of a dome type tent includes a disk shaped based section with a central aperture surrounded by upstanding walls at each of opposite sides of the base section. The upstanding walls are reinforced by cross walls in the aperture. Sockets are formed by walls on opposite sides of the base section. The sockets are equiangularally arranged so that the socket extend radially about the base section for receiving end portions of the tubular poles. An elastic member extending from the end of each pole is threaded through an opening in an anchor wall separating a socket from the central aperture. The end portion of the elastic member in the aperture is tied in a knot whereby the pole cannot be completely separated from the connector.
