Abstract
Abstract An assembly kit has a structural element having two elongated leg portions, and a hinge portion pivotally connecting the leg portions with one another in a direction of elongation thereof and together with the leg portions forming an integral member. Means is provided for connecting the structural element with another structural element. Two such structural elements may be located laterally adjacent to one another and connected with one another by a plate-like connecting piece which overlaps juxtaposed end sections of the structural element and is connected with the latter by the connecting means. Three such structural elements may be located relative to one another so as to form a substantially triangular hollow support element, and a substantially triangular connecting piece may be inserted in a hollow of the support element and connected with the structural elements by the connecting means. The connecting means may include openings formed in the structural elements and adapted to be aligned with openings formed in the connecting piece. Connecting members such as pins or bolts may be inserted in the thus-aligned openings so as to connect the structural elements with the connecting piece. The connecting members may have head portions which are recessed in the respective openings and may be flush with outer surfaces of the structural elements.
