Abstract
A collapsible railing having an upper rail and a plurality of posts hingedly attached to the upper rail at spaced apart locations. A crank including a shaft portion and an arm portion which is mounted for rotation about the long axis of the shaft portion is connected to each post. An actuator actuates the motion of the crank to pivot the posts and the upper rails between a collapsed position in which each post is oriented generally horizontally, and an erect position in which the posts are in an upright position.

A collapsible railing comprising:
- an upper rail;
- a plurality of posts hingedly attached to the upper rail at spaced apart locations;
- crank means for each post, said crank means including a shaft portion and an arm portion, said shaft portion being mounted for rotation about its long axis, each post being mounted at one end of the shaft portion, said arm portion being mounted at the other end of the shaft portion;
- and
- actuator means for actuating motion of said crank means to pivot the posts and the upper rail between a collapsed position in which each post is oriented generally horizontally, and an erect position in which the posts are in an upright orientation.
A collapsible railing in combination with a walkway located on top of a beam of an elevated railway system in which a passenger car is supported to the side of the beam for movement along the beam, the collapsible railing comprising:
- a pair of laterally spaced upper rails;
- a plurality of posts along laterally opposite sides of the walkway, the posts on each side of the walkway being hingedly attached to one of the upper rails at locations spaced longitudinally of the walkway;
- crank means for each post, said crank means including a shaft portion and an arm portion and being mounted for rotation about the long axis of said shaft portion, each post being mounted at one end of the shaft portion, said arm portion being mounted at the other end of the shaft portion;
- and
- actuator means for actuating motion of said crank means to pivot the posts and the upper rail between a collapsed position in which each post and upper rail is oriented generally horizontally, and an erect position in which the posts are in an upright position and the upper rail is spaced above a side of the walkway.
