US Patent 11692383 Hinge assembly for elevational rails

An articulated attachment assembly and a rail system and method of installation for rail installations in which there is an elevational change between vertical supports, in which the articulated attachment assembly eliminates the need for field mitering of components and provides instead a first articulated hinge assembly having a first mounting block to be attached to the first support, a second mounting block to be attached to the first rail connection block, and a hinge member to couple the second mounting block to the first mounting block and enable the second mounting block, the first rail connection block, and the rail to pivot together relative to the first mounting block and the first support.
