Patent attributes
A stair-climber includes a base, a first inclination unit, a second inclination unit, a step unit, and a sensor. The front end of the first inclination unit is slidably disposed at the base. The second inclination unit is pivotally connected to the rear end of the first inclination unit. The rear end of the second inclination unit is pivotally connected to the base. The inclination angle of the second inclination unit is adjusted by an inclination unit regulator disposed between the first and second inclination units. The step unit is disposed at the second inclination unit and has multiple steps. The steps undergo angle adjustment with a step regulator disposed at the second inclination unit and thus tilt at angles suitable for a tread performed by users ergonomically. The sensor is disposed at the rear end of the second inclination unit to detect whether the users have lost footing.
