Claims

[Scope of Claim for Utility Model Registration] A storage frame that accommodates an evacuation ladder that is fitted into an opening in the floor and has open upper and lower surfaces, and a top surface of the storage frame that rotates vertically on the front side of the storage frame. an upper lid that opens and closes the opening; a lower lid that rotates vertically on the front side of the storage frame to open and close the lower opening of the storage frame; a second upper arm, the second upper arm having one end rotatably supported in the vertical direction on the side wall of the first upper arm and the storage frame, and the other end mounted on the other end of the first upper arm so as to be rotatable in the vertical direction; and a first lower arm whose one end is attached to the lower cover so as to be rotatable in the vertical direction, and a first lower arm whose one end is attached to the other end of the first lower arm so as to be rotatable in the vertical direction and whose other end is rotatable in the vertical direction. a second lower arm mounted so as to be rotatable in the vertical direction at a pivot point shifted toward the other end from the pivot point of the second upper arm; and a base end portion vertically relative to the second lower arm. A lower cover closing position setting arm is rotatably attached to the pivot point and extends with its tip side substantially oriented toward one end of the second lower arm, and the lower surface of this lower cover closing position setting arm is selected. The two arms are coupled to each other in a relatively rotatable state in which both arms are caused to protrude downward from the lower surface of the second lower arm by a protrusion amount that is selected, and in a relative non-rotatable state in which both arms are prevented from varying in the selected protrusion amount. An evacuation ladder storage device comprising: a protrusion amount adjustment mechanism; and a support member that is attached to the storage frame and supports the lower surface of the lower cover closing position setting arm when the lower cover closes the lower opening of the storage frame. box.
