发明名称 Apparatus for pedestrian railing and method of making
摘要 A sturdy aluminum pedestrian and bicyclist safety railing that reduces the amount of welding required during construction, comprising top and bottom rigid bars, each having a longitudinal, radially extending exterior passage and a plurality of aluminum pickets mounted within said bar top and bottom channels and held apart by a plurality of spacer plugs that interlock and fit snugly within each top and bottom bar channel and act as spacers to separate the pickets. The top and bottom bars may be welded together at each end of the railing to hold the entire unit together, retaining the plurality of rigid pickets that are substantially perpendicular (or inclined) to the top and bottom bars. The pickets are supported in the top and bottom bar channels without welding for increased strength and reduced cost of construction.
