Abstract: A rain gutter for an associated building which includes an elongated trough shaped member together with means for mounting the trough shaped member on the associated building in a position in which the trough shaped member will hold at least temporarily a quantity of water. The means for mounting also allows movement of the trough shaped member to a second position in which the trough shaped member will not hold water even temporarily and the trough shaped member is in substantially intimate contact with the associated building along substantially the entire axial extent thereof. The trough shaped member may be manufactured of a flexible material and the means for mounting may constrain the flexible material in the first and second positions. The flexible material may be a plastic material. In one form of the invention the trough shaped member may comprise an elongated rigid member and hinge means for carrying the elongated rigid member.
