1. A railing system comprising:
a walkway having a top surface that is generally planar, a bottom surface positioned opposite to the top surface, an inner side and an outer side that are connected to the top surface and are substantially perpendicular with respect to the top surface wherein the top surface has a first end and a second end wherein the second end is located opposite to the first end wherein the inner side and the outer side extend from the first end of the top surface to the second end of the top surface; a frame connected to the outer side of the walkway and having a channel and a side wall wherein the channel extends below the top surface and separates the side wall from the walkway; a railing having a handrail and uprights wherein the uprights extend from the channel and connect to the handrail wherein the uprights pivot relative to the handrail wherein the uprights connect to the frame and further wherein the uprights pivot relative to the frame; a lever connected to the railing through a slot extending through the frame to define an opening in the frame wherein the lever extends through the opening and moves within the opening as the railing moves between the collapsed position and the upright position wherein the lever pivots relative to the frame and further wherein the lever moves the railing from a collapsed position to an upright position wherein the uprights are generally perpendicular with respect to the top surface in the upright position and further wherein the uprights are located within the channel in the collapsed position; a rod extending from the lever and having a length defined between a first end and a second end positioned opposite the first end wherein the rod has a spring, a handle on the first end of the rod and a plunger on the second end of the rod; a plate mounted to the frame wherein the plate is generally planar and is substantially perpendicular with respect to the walkway; and wherein a perpendicular guide rail is connected to the plate and having a curve having a first locking end and a second locking end wherein the first locking end is positioned remotely from the second locking end wherein the rod and the lever move from a first position adjacent to the first locking end to a second position adjacent to the second locking end wherein the plunger contacts the curve as the rod and the lever move between the first position and the second position wherein the first locking end and the second locking end are shaped to enclose the plunger wherein the plunger extends into the first locking end in the first position to secure the railing in the upright position wherein the spring applies a force to the plunger to move the plunger in the first locking end wherein the handle applies a force to the spring and retracts the plunger from the first locking end wherein the plunger extends into the second locking end in the second position to secure the railing in the collapsed position and further wherein the spring applies a force to move the plunger in the second locking end. |
