Abstract
A step assembly includes a tread and an actuator. The actuator is operably coupled to the tread and configured to selectively reciprocate the tread between a raised position and a lowered position. The actuator is rotatably coupled to the actuator mount, which is slidably coupled to a frame. A spring selectively maintains a position of the actuator mount relative to the frame.
Claims7
A step assembly for providing access between a lift platform and an alighting surface, the step assembly comprising:
- (a) a tread;
- (b) an actuator operably coupled to the tread and configured to selectively reciprocate the tread between a raised position and a lowered position;
- (c) an actuator mount, the actuator being rotatably coupled to the actuator mount;
- (d) a frame fixedly positioned relative to the alighting surface, the actuator mount being slidably coupled to the frame;
- and
- (e) a spring selectively maintaining a position of the actuator mount relative to the frame.
