发明名称 Bunk bed ladder bracket
摘要 A bracket for mounting a bunk bed ladder from the bed rail of an upper bunk bed which engages both the top and inner bottom edge of the bed rail to prevent the bunk bed ladder from being accidentally lifted off and disengaged from the bed rail, to prevent the ladder from shifting along the bed rail, to reduce twisting of the rail and strain on the post or leg of the bunk bed, thereby reducing failure of bed rails, bed posts, and the ladders, and to prevent the ladder from tilting outward while climbing.
