  • Patent number: 9169651
    Abstract: A stairway system. The stairway system includes a plurality of spaced apart treads, a handrail and a baluster assembly. The baluster assembly includes at least one baluster per tread. The baluster includes at least one rake anchor adapted to abut the angled support surface of the handrail adjacent to one end of the baluster, a rake shoe adapted for concealing the interface between the rake anchor and the angled support surface of the handrail and an anchor assembly including an anchor adapted for receiving the other end of the baluster.

  • Patent number: 7178791
    Abstract: A hinge assembly is described which can be assembled by snapping together moldable half-cap pieces about the end of a baluster pierced through by a hole. The baluster turns about spindles formed by the half-caps. The half-caps may be fixed together by press-fit mating surfaces and may be placed within a mating groove defined by a hand rail or shoe rail. The half-cap pieces and the hole are not readily apparent in a finished staircase containing the hinge assembly. The hinge assembly successfully employs pin top balusters, as well as rectangular balusters. Alternatively, a hinge assembly is described which can be inserted into the bore of an end-bored bluster, fastened to the inside of the bore, and pivotally attached to a flange suitable for attachment to a rail. The hinge assembly requires no external modification to the normally exposed surfaces of the baluster. The flange includes an H-shaped foot which may be concealed in a groove defined by a hand rail or a shoe rail.

  • Patent number: 7077386
    Abstract: A hinge assembly which can be inserted into the bore of an end-bored bluster, fastened to the inside of the bore, and pivotally attached to a flange suitable for attachment to a rail. The hinge assembly requires no external modification to the normally exposed surfaces of the baluster. The flange includes an H-shaped foot which may be concealed in a groove defined by a hand rail or a shoe rail. The pivot point is raised slightly above the inner surface of the groove to prevent any unsightly gap, termed “bird's' mouth” in the industry, adjacent the baluster.
