Adjustable staircase and height-adjustable platform with adjustable staircase
An adjustable staircase includes an upper stair, a lower stair, a first bar and a second bar. The vertical distance between the upper stair and the lower stair is adjustable. Also, each bar is coupled to each of the upper and lower stairs, and the first bar is configured to function as a guard. As a result, the first bar blocks a pinch point between the first and second bars.
