の範囲第1項又は第2項記載の避難用梯子装置。[Scope of Claim for Utility Model Registration] (1) A frame with a rectangular top surface having an upper frame and a lower frame at the top and bottom and an opening that opens in the vertical direction;
an upper lid which is rotatably attached to the upper frame and which freely opens and closes the upper part of the opening; a lower lid which is rotatably attached to the lower frame and which freely opens and closes the lower part of the opening; The frame is constructed of a pair of left and right extensible bodies with a large number of main side plates and sub-side plates pivoted in a pantograph manner, and is connected to the frame via a base shaft horizontally fixed to the upper end of a pair of first main side plates located at the uppermost end. It has a folding ladder that is attached to the base frame of the body so that it can be suspended, and when the upper lid is rotated upward and opened, the lower lid is also opened and the folding ladder can be lowered and suspended, so that it can be used in an emergency. In the evacuation exit, which allows escape through the opening via the ladder, the base end of the damper means is connected to the base shaft and is connected to the upper part of the second main side plate, which is connected to the first main side plate. An evacuation ladder device characterized in that the tip portions of damper means are connected. (2) A pair of brackets having a tapered front end portion are fixed to the base frame, a recessed receiving portion is formed below the tapered portion of the bracket, and the base shaft is connected to the upper end of the bracket. When the folding ladder is in a lowered state, a restraining shaft horizontally fixed to the upper end portions of a pair of first secondary side plates pivotally connected to the first main side plate is fitted into the recess receiving portion. An evacuation ladder device according to claim 1 of the utility model registration claim. (3) A sliding auxiliary metal fitting is provided in a continuous manner with the bracket at a position of the base frame corresponding to the installation position of the pair of telescopic bodies, and a sliding auxiliary metal fitting is provided as a contact guide when the folding ladder is lowered. 2. An evacuation ladder device according to claim 1 or 2, characterized in that the evacuation ladder device descends while being lowered.
