Abstract
Description
Technical Field
[0001] The utility model relates to a stowable staircase structure and is applicable to the technical field of staircase equipment. Background Art
[0002] Stairs are often provided between two adjacent floors in a building, and are used to facilitate the passage of people between the upper and lower floors. However, since the stairs need to be provided with step plates arranged in a ladder shape, the stairs between the upper and lower floors need to occupy a large area. At present, in order to reduce the floor space occupied by the stairs, a telescopic staircase is provided on the upper floor. When the stairs are needed, a person on the lower floor needs to pull the telescopic staircase on the upper floor, extend it from the lower staircase, and overlap it on the lower staircase before the stairs can be used. However, the telescopic staircase requires a person on the lower floor to pull the telescopic staircase, and it is not convenient to use the telescopic staircase when the person is on the upper staircase. In addition, since there is no stable connection between the telescopic staircase and the lower floor, the stability of the telescopic staircase is poor, which has certain safety hazards.
