US Patent 8695948 Railing assembly

An improved railing assembly is comprised of a plurality of pickets, a top rail, an inner rail and a bottom rail. The inner rail is pivotally attached to the pickets with fasteners. The fasteners are hidden from view by the top rail. Stiffeners project from the top rail and from the bottom rail. The stiffeners each either interface with another stiffener or a seat on the inner rail to provide rigidity to the assembly. The bottom of the railing assembly is substantially covered by the bottom rail. The angle between the pickets and the top rail is adjustable such that the pickets may be vertically oriented, while the top rail is parallel to a sloped terrain upon which the railing assembly is installed.
