FIELD: folding sheds. SUBSTANCE: folding shed has canvas and vertical posts supporting the canvas and frame. The latter consists of trusses connected to posts and made of pairs of links hinged to one another. Truss is made for stretching from folded position between posts to stretched position. To increase the free space inside the given structure and its strength and stability, the canvas has at least three sides and three corners; located under each corner is one of the posts. Each post has upper and lower ends. Trusses joined to each post are located over perimeter and each having the first and second links. The first link exterior end connected to upper end of one post, while exterior end of the second link is connected in sliding to the same post. The first link has longitudinal center and point of turning displaced from center to exterior end through a definite distance. The second link also has point of turning displaced from center through a definite distance too. The first and second links are hinged with each other in the form of scissors. In stretching from folded position, perimeter truss rises above the post. Folding shed has at least two central trusses consisting of two links which are also hinged to each other in the form of scissors. Presence of the perimeter and central trusses allows shed structure with slopes to ensure removal of precipitation from canvas. EFFECT: improved design. 20 cl, 7 dwgo
