[ I claim:] [1.] A new and improved collapsible railing comprising, in combination:a vehicle with a roof;a generally rectangular railing including a tubular rod with a linear rear section, an arcuate front section, and a pair of linear side sections defining an interior space;a plurality of collapsible stanchions, each of the stanchions having an upper end and a lower end, the lower end comprising a base mounted to the roof of the vehicle and a pivotal means allowing each of the stanchions to collapse;a plurality of generally T-shaped sleeve joints, each of the sleeve joints having a horizontal upper sleeve secured about the railing and a lower sleeve pivotally coupled to the upper sleeve and secured about the upper end of the corresponding stanchion; anda ladder access section comprising a portion of the railing adjacent to a ladder coupled to the vehicle, the ladder access section hingably coupled at a first end to a sleeve joint and releasably coupled at a second end to a sleeve, the ladder access section further having an upright orientation for allowing access to the interior space of the railing and a prone orientation for precluding access thereto;wherein at least one of the pivotal means comprises a locking hinge having a circular first portion with a plurality of teeth formed in an exterior periphery thereof and a threaded aperture centrally disposed therein, the first portion coupled to the base of the stanchion; a circular second portion with a plurality of teeth formed in an interior periphery thereof and a threaded aperture centrally disposed therein, the second portion having a sleeve coupled thereto for securing about the lower end of the stanchion; and a wing bolt for inserting within the threaded apertures and having a first disengaged orientation for allowing disengagement of the teeth thereby allowing the stanchions and railing to swivel between an upright and collapsed position, the wing bolt further having an inserted orientation for allowing engagement of the teeth thereby precluding the stanchions and railing from swiveling between the upright and collapsed position.
