摘要: A cover assembly for use with a base structure such as hot tub comprising member mounted rotational movement to the by mounting arms. The arms are arranged relative so that travels along path from covering positioning an open position, this having first portion extending between position and intermediate location area of member, second area. is in manner on side portion, gravitational force tends move position. There springs operatively connected either or urge toward oppose thus permit be more easily moved positions.
