FIELD: testing technology.
SUBSTANCE: invention relates to foldable semi-automatic fold-out demonstration stands. The stand comprises a compartment which has a bearing wall, two side walls and is able to change the state between the folded and the unfolded state and the open operating state, in which it is ready for placement the article in it. The bearing wall is located between the sidewalls. Valves keep the compartment in the folded and open state, and the means of fastening with brace struts along with the bearing wall form the means of transmitting force. Each side wall is a thick wall which forms at least one dihedral angle with two faces, extending from the articulated edge, and which can be folded along the edge and along another fold line intersecting with the edge. In the unfolded state the edges are rigid and form a part of the means of fastening with brace struts.
EFFECT: simplification of the design while increasing its strength.
