Abstract: 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.

Abstract: A modular block toy and kit that includes a male cubic unit piece having a plurality of faces with a male node extending from each respective face of the plurality of faces, and a female piece having a plurality of faces and corners formed by three intersecting faces, the female piece having a female component formed on a respective face of each of the plurality of faces that is sized and shaped to receive a respective male node enabling connection using any side of the female piece and any side of the male piece, and in which all sides of the female and male pieces with the snapping and interlock design are identical, enabling the pieces to be snapped together using any side of the female or male piece to achieve build out indefinitely in any direction.
