The present invention is an automatic invertible railing and, more specifically, to an automatic invertible railing which maintains a railing unit to be erect when water level is usual and is automatically inverted when the water level is increased. The invertible railing includes a case including an internal receiving space, hinges on both lateral surfaces, and buoyancy unit guide grooves which are composed of a straight fixed section and an arch-shaped guide section, on the lower sides of the hinges; a pair of posts which is formed on both lateral surfaces of the case and includes hinge joining grooves joined to the hinges, weight joining grooves on the lower sides of the hinge joining grooves, and buoyancy unit moving grooves at the lower sides of the weight joining grooves; a weight unit which is formed inside the internal receiving space of the case and fixed and joined to the weight joining grooves formed on the posts and which includes an internal receiving space; and a buoyancy unit composed of a pair of buoyancy unit shafts which is joined to the buoyancy unit guide grooves formed on the case and a buoyant body formed between the buoyancy unit shafts. |
