摘要

Railings for an opening (1) in the ground comprise four posts (9, 23) connected by at least three horizontal traverses. The posts are rotatably fixed at the lower end to parallel axles. A longitudinal traverse (13) is hinged to the upper end (11) of the posts of the first post pair. A guiding and holding device (15, 17) is molded on the free ends (14) of the two longitudinal traverses for locking the longitudinal traverses on at least one transverse traverse (21, 25) connecting the posts of the second post pair. Preferred Features: When not in use the posts lie horizontally on the opening and the free ends of the longitudinal traverses are loosely supported on the transverse traverse.
