O Utility Model Registration Claims A frame attached to an opening in the ceiling, which is folded and stored above the opening when not in use, and unfolded between the frame and the floor when in use. In a ladder device equipped with a ladder main body consisting of a plurality of upper and lower ladder sections, the rack is passed over.
Between the edge frame and the lower end of the upper ladder part, a bendable drive link is provided at the intermediate part so as to extend when the ladder main body is deployed and extended, and to bend when the ladder body is folded and stored. The drive link is provided with a locking means for maintaining its extended state, and a locking means is provided between the edge frame and the vicinity of the pivot portion opposite the edge frame J of the drive link to prevent the drive link from being bent when the ladder body is stored. an attached body such as a gas spring that exerts a spring force in a direction in which In the extended position, the pivot portion is deviated from the axis of the biasing body and the spring force of the biasing body is applied to the drive link in the opposite direction to when the ladder body is stored.

る天井用はしご装置。An edge frame attached to the opening in the ceiling, and multiple upper and lower parts that are folded and stored above the opening when not in use, and are unfolded between the kitakami edge frame and the floor to pass the rack. In a ladder device comprising a ladder main body consisting of a step ladder section, a drive link that can be bent at an intermediate portion between the edge frame and the lower end of the upper step ladder section extends when the ladder main body is expanded and extended. The drive link is provided to be bent in the folded and stored state, and the drive link is provided with a locking means for maintaining the extended state, and an arm is provided protruding near the pivot portion relative to the edge frame. A biasing body such as a gas spring that exerts a spring force in the direction of bending the drive link when the ladder main body is stored is disposed between the edge frame and the edge of the drive link at a position near the extension of the upper ladder section. The pivot part relative to the frame is located on the axis of the biasing body, and in the extended position, the pivot part deviates from the axis of the biasing body, and the spring force of the biasing body is applied to the drive link □ When the ladder body is retracted A ceiling ladder device characterized by being configured so that it can be added in the opposite direction.
