发明名称 Canopy-support hinge device
摘要 A canopy-support hinge comprising a base member and bolt member is provided. The hinge base member is provided with an open side having a hinge bolt aperture. The open side of said base member is narrower than the diameter of the bolt aperture. The hinge bolt member is provided with two flat parallel sides to make the bolt narrow enough to be passed through the open side but to be contained when the bolt is rotated to different positions. A flanged bolt head and connector means on the bolt member for attaching canopy support tube members thereto renders this device advantageous for forming canopies on boats and on other structures.
