发明名称 Roof or access hatch safety railing system
摘要 A roof hatch safety railing for increasing a person's safety as he or she climbs onto a roof or platform of a building from a roof or access hatch is disclosed. The safety railing includes two poles where one pole is attached to the right side of a roof hatch and the other pole is attached to the left side of the hatch. A person may grab the poles as he or she climbs from the roof or access hatch ladder, through the hatch, and onto the roof or platform. The poles are also spaced away from the hatch, thereby allowing enough clearance for a lid of the hatch to close and cover the hatch. The railing may be modified to accommodate various types and sizes of roof or access hatches.
