FIELD: physics.
SUBSTANCE: support has at least one screen made from solid and folding material. The screen has an information display surface, several insertions and flexible connectors which make the information display surface bulging. The insertions counteract the force of resilient arresting apparatus and hold the information display surface in bulged state. The length of the insertions is equal to the distance between two lateral edges of the screen in its bulged state. The screen extends beyond the boundaries of the information display surface through two sets of lateral projections. A support insertion enters the dihedral angle formed by each lateral projection. The resilient arresting apparatus interact with the support insertions and projections to generate a horizontal arresting force and a vertical force acting in opposite directions. The vertical force holds the support insertions at the required height in the bulged state of the screen. The resilient arresting apparatus include at least one closed flexible connector. The flexible connector interacts with one projection of the screen and with the end holding and locking part of the insertion.
EFFECT: invention enables to hold support insertions at the required height in bulged state of the screen and prevents wedging between projections and support insertions.
