    Description: The invention relates to a screen and to a method for producing such a screen, and to a method for using such a screen.
    Most prior art umbrellas have a screen stick and attached thereto collapsible, a string-carrying, umbrella frame. In the open state, the fabric is in dome shape on the umbrella frame and is held by this in a stretched state. This dome shape may be detrimental in windy weather when the wind enters the interior of the dome shape. Strong wind forces acting on the inside or underside of the dome shape can lead to a folding over of the dome shape into a dish shape. This folding in most cases means that the umbrella frame is deformed unduly and the screen is unusable. Therefore, solutions were sought to avoid the folding of the umbrella frame by strong wind forces.
    US 5 878 763 A shows a screen with a telescopically extendable umbrella pole and a umbrella frame. The umbrella frame consists of a shield spokes formed, a string-bearing umbrella spider and spokes. The tension spokes are hingedly connected to the umbrella spokes and converge on the umbrella pole in a sleeve which is longitudinally displaceable along the umbrella pole so as to be slidable between a closed position and an open position. The covering consists according to the solution shown in US Pat. No. 5,878,763 A, in contrast to known screens in the open position, of a dome-shaped central area and a jacket area adjoining the dome-shaped central area, which is essentially conical, the opening width of the cone being dome-shaped Central area increases seen. Although this screen offers a larger attack surface in substantially horizontal wind forces, however, the cone has a reinforcement of the edge region result. This means that the conical mantle area can prevent folding over, at least when the winds are not too strong.
    Another solution is to provide a linkage which is mounted on the top of the screen, which is shown in DE 10 360 864 A1. For the screen spider results in an increase in stability against wind forces, since the covering presses with wind forces from below against the linkage of the umbrella spider and therefore the range of motion for the covering is limited by the rod and thus folding the spider is likely to be difficult.
    All the solutions described so far have in common that a folding over of the linkage is essentially irreversible and can damage the linkage or the stringing. It has therefore been proposed in GB 2 525 477 A to use a linkage of flexible ribs provided with a stringing. Due to their flexibility, these ribs can deform reversibly in wind forces. Although this avoids damage to the ribs or the covering by wind forces, however, the surface of the covering changes with wind forces, so that the area protected against precipitation changes and / or is smaller. The ribs can be completely absorbed in the interior of the Schirmstocks. A disadvantage of this solution is, on the one hand, that the diameter of the umbrella pole increases and that moisture gets into the interior of the umbrella pole when the clothing is pulled in. This moisture remains in the interior of the canopy until the boom is extended again. Therefore, the fabric or ribs may be damaged by the standing wet or at least have stains or other aesthetic defects.
    Therefore, there is a need for a solution that is on the one hand insensitive to the attack of wind forces and on the other hand prevents standing moisture.
    The object of the invention is thus to provide a screen, the shield spider has a flexibility that allows for attack of wind forces reversible deformation of the screen spider, without significantly changing the scope of protection of the screen spider. Another object of the invention is to protect the umbrella spider and the covering from stagnant moisture.
    The object is achieved by a screen having the features of the characterizing part of claim 1. Advantageous embodiments of the screen are the subject of the dependent claims.
    For a plate-shaped stiffening element or such a skin is their bulkiness. The mobility in a normal plane to the plate plane is limited to the adaptation of an uneven, for example, concave or convex curved body. If the plate-shaped stiffening element or the skin are not produced in the same place, appropriate arrangements for the transport and storage of the known from the prior art stiffening elements are required.
    The screen contains a structural element, which can be clamped and forms the screen in the tensioned state. The structural element contains a base element and an insert element, wherein the base element is designed as a foldable, flexible, flat leaf element.
