ABSTRACT:
The present invention relates to a boat shade comprising a cover and a frame for it formed of three inverted U-shaped components. Two of these inverted U-shaped components, carrying the cover, are arranged so as to flank the third inverted U-shaped component, to which they are hinged, and which is vertically erected and secured by its ends to the sides of a boat. Each of the hinges disposed at each end of each of the inverted U-shaped components, carrying the cover, is formed by an axle arranged at this end of the component and capable or moving in a horizontal direction outwardly in relation to the vertically erected component and a bushing mounted on it. A spring-actuated stop locks the axle in its extreme positions when the cover is either fully unfolded, or when it is partially folded, that is when one of the inverted U-shaped components, carrying the cover, is placed on the other component.
The invention may be used on small vessels and boats meant for tourism and recreation, and, more particularly, as an attachment to foldable boats.
