A feature of an embodiment of the present invention is the use of modular components. Additionally, a feature of an embodiment of the invention is the ability of components of the stanchion to be interlocked and securely connected by means of a single bolt. Features such as these are significant in that the stanchion can be produced by manufacturing smaller common components and interlocking and connecting them together in different configurations to produce a variety of stanchion types.
- Embodiments of the present invention permit resolution of several problems or limitations of existing chair stanchions. Problems overcome by and benefits of embodiments of the present invention include: elimination of the need for dedicated one piece stanchion castings or permanent welded steel stanchions by using a plurality of smaller components, which can be assembled together in different configurations to produce a variety of different stanchions; easy conversion between right hand and left hand stanchions in the field; reduction of the number of components and space requirements for repair or replacement parts typically kept in inventory for performing maintenance on stanchions by using common components that can be easily disassembled , replaced, and re-assembled by means of a single bolted connection; flexible design permits easy conversion of stanchions to different slopes or mounting configurations and does not require complete replacement of the stanchion.
