• a emergency railing for refuge 1 includes a main frame 10 pivotably hinged to an outer wall 101 of a building; a main frame restricting element 20 for restricting the main frame 10 selectively pivotably; a foothold 30 hinged to a safeguard 12 of the main frame 10 and provided with a plurality of support bars 33 to support a rescuee's weight; and an auxiliary railing 40 pivotably hinged to a front end of the foothold 30 such that the rescuee can be prevented from an accidental fall.
• the main frame 10 is pivotably fixed to an opening of the outer wall 101 of the building, such as a balcony and a window.
• the main frame 10 serves as a railing to prevent an accidental fall in ordinary times, while it is pivoted downward in an emergency to provide a structure for accommodating a rescuee.
• the main frame 10 includes a pivot 11 disposed at a lower end, a safeguard 12 disposed above the pivot 11, and a connecting bar 13 for connecting the pivot 11 with the safeguard 12.
• the safeguard 12 is disposed, above the pivot 11, at a height sufficient to prevent a rescuee from an accidental fall.
• the pivot 11 is fitted into a bracket 102 which is fixed on the outer wall 101 of the building.
• the pivot 11 serves as a rotating axis around which the main frame 10 rotates.
• the bracket 102 is fixed to the building.
• the bracket 102 includes a pivot holder 102a into which the pivot 11 is fitted.
• the pivot 11 is fitted into a predetermined number of brackets 102 disposed in a line with predetermined spaces therebetween so that the pivot can be supported stably by the brackets 102 during the rotation.
• a torsion spring 16 is provided to the pivot 11 to absorb impact energy generated during the rotation of the main frame 10.
• the safeguard 12 is disposed above the pivot 11 and forms an upper end of the main frame 10.
• the main frame 10 is disposed at a height appropriate to prevent a rescuee from an accidental fall.
• the safeguard 12 is disposed under the pivot 11 and forms a lower end of the main frame 10 when the emergency railing for refuge 1 is deployed in an emergency.
• a connecting bar 13 connects the safeguard 12 with the pivot 11.
• the connecting bar 13 has a length corresponding to a height of a common railing of a building. Both ends of the connecting bar 13 are connected to the pivot 11 and the safeguard 12, re- spectively, so that the connecting bar forms one side of a border of the main frame 10.
• Adjacent two parallel connecting bars 13 are interconnected with a plurality of flat bars 14 arranged in parallel to each other.
• the plurality of flat bars 14 which are used as a foothold during a rescue are effective in preventing a flame from spreading upstairs as well as in preventing an accidental fall of the rescuee.
• the flat bar 14 may be a board of a predetermined width. Both ends of the flat bar 14 are connected to the respective connecting bars 13.
• the flat bar 14 is slopingly arranged so as to prevent the flame from spreading upstairs and obtain a well-lighted environment. When a fire breaks out, flames are spread upstairs. At this point, the flat bar 14 inclined upward can prevent flames generated in downstairs from spreading upstairs.
• the flat bar 14 of a predetermined width is provided such that the inside of the balcony is well lighted.
• main frame 10 may further include the safeguard for preventing a rescuee from an accidental fall.
• the safeguard includes a side railing 15 that is provided at the center of the connecting bar 13 disposed on both ends of the main frame 10.
• the side railing 15 has a predetermined length and is hinged to the connecting bar
• the side railing 15 Since one end of the side railing 15 is hinged to the connecting bar 13, the side railing 15 is freely rotatable. However, due to a stopper 15a adjacent to the hinged portion, the side railing 15 can be rotated until it is placed in parallel with the ground.
