Modular stairway and balcony railing system
DCFirst Claim
1. A modular railing system for use at a stairway and a balcony having an elongated base support member and an elongated handrail adapted to be supported spaced from and above said base support member, said railing system comprising:
- a plurality of spaced apart, side by side balusters supported on said base support member and connected to said handrail, each of said balusters having a single generally vertically extending stanchion part comprising opposed rodlike distal ends insertable in corresponding bores in said base support member and said handrail, respectively, and a barrier part having a predetermined ornamental shape connected to said stanchion part, and extending laterally substantially from only one side of said stanchion part, said barrier parts of said balusters being of an ornamental shape such as to provide a predetermined ornamental pattern when arranged as a balcony and as a stairway having a slope of between about 25°
to 50°
, and said barrier parts occupying space between said base support member and said handrail when arranged as a generally horizontal balcony railing and as a stairway railing for a stairway having a slope of between about 25°
to 50°
while forming a continuous barrier to pass through of an object comprising a ball having a predetermined diameter of about four inches.

Abstract
A modular railing system for straight or curved stairways and straight or curved balconies includes a selected number of balusters, each having a stanchion for connection to a base support member of the balcony or stairway and a handrail member of the balcony or stairway railing system and a barrier part connected to the stanchion. The barrier parts may comprise predetermined ornamental scroll-shaped portions connected to the stanchions at spaced apart points between opposite distal ends of the stanchions and projecting laterally from the stanchions. Alternatively, the stanchions may project from opposite ends of the barrier part. Each baluster has a predetermined ornamental and functional shape to provide a repeating pattern of the railing system throughout its extent and to provide a maximum pass through dimension to comply with regulatory requirements. The stanchion parts and barrier parts of each baluster are proportioned to provide modular railings for stairways having substantial differences in slopes. The balusters are preferably fabricated of wrought iron or other workable metals and the barrier parts of each baluster may be formed to have a predetermined radius of curvature out of a vertical plane for use in conjunction with curved stairways or balconies.

4. A modular stairway railing system for a stairway including an elongated base support member extending along said stairway and providing a predetermined slope of said stairway of between about 25°
- to 50°
with respect to a horizontal tread of said stairway and an elongated handrail adapted to be supported spaced from and above said base support member, said railing system comprising;a plurality of balusters supported on said base support member spaced apart from each other in side by side relationship and extending between said base support member and said handrail, at least selected ones of said balusters each comprising a single vertically extending, elongated rod stanchion part having opposed distal ends supported on said base support member and connected to said handrail, respectively, and an ornamental barrier part comprising plural curved scroll-like portions connected to said stanchion part between said distal ends and extending laterally from only one side of said stanchion part, said scroll-like portions of one baluster being shaped to cooperate with corresponding curved scroll-like portions of an adjacent baluster which is inverted with respect to said base support member, said handrail and said one baluster, said balusters being spaced apart along said base support member at predetermined distances from each other and adjacent to each other to provide a predetermined ornamental pattern and to provide a protective barrier for said stairway having a predetermined maximum pass through dimension for said railing system of an object comprising a ball having a diameter of about four inches. - View Dependent Claims (5, 6, 7, 8)

9. In a modular railing system for use at a stairway having a slope of between about 25°
- to 50° and
a generally horizontal balcony, a plurality of spaced apart balusters each comprising a single elongated rod-like stanchion part having opposed distal ends insertable in corresponding bores in a base member and a handrail, respectively, and a barrier part connected to said stanchion part and projecting laterally from substantially only one side of said stanchion p between said distal ends of said stanchion part and supported by said stanchion part in said railing system, each of said barrier parts comprising plural curved scroll-like portions providing a single predetermined pattern when said balusters are disposed in said railing system at a balcony and a stairway, each of said barrier parts having an overall length of between about 30 inches to 40 inches, an overall width of between about 10 inches to 12 inches and a radius of curvature out of a plane containing said stanchion part of not less than about 48 inches, and said stanchion parts and said barrier parts cooperate to provide a predetermined maximum pass-through dimension for said railing system defined by a ball of a diameter of not more than about four inches.
