发明名称 Rooftop opening safety railing
摘要 An improved safety railing for use with an opening in a rooftop or other location. The safety railing is easily securable to the curb, or upstanding wall, surrounding the opening. The securing mechanism of the safety railing also takes advantage of any outwardly protruding lip on the curb of the opening. The safety railing features a base portion that is reversibly securable to the curb portion of the opening and a railing portion that rises above the base portion. The base portion includes a pair of side members that are shaped and sized to abut the upstanding portion of the curb. Each of the curb members also present a surface to underlie the lip of the curb and engage it if the base portion is lifted. The base portion also includes two base members that interconnect the two side members. The base members are preferably formed of round hollow stock and have threaded nuts welded to each axial end. Threaded bolts are used to affix the side members to the base members. Further, the base portion of the device provides a somewhat flexible joint and pretensioning mechanism that preclude significant bending of the base members after significant use.
