Abstract: The invention relates to a holding device for securing at least one flat element, in particular a facade element, comprising at least one substructure securing means, at least one flat element securing means and at least one transversal force absorbing means which interconnects the substructure securing means and the flat element securing means and which absorbs forces that are effective in the plane defined by the flat elements, characterized in that the holding device comprises at least one to energy absorbing means which absorbs energy that is introduced into the holding device by forces that act perpendicularly to the plane defined by the flat elements.

Abstract: A cable end anchorage for fastening at least one cable at a supporting structure includes at least one first connecting element for connection with the supporting structure, at least one second connecting element for connection with the cable and at least one coupling element for connection of the two connecting elements in a force-transmitting manner. In the region of the coupling element, an overload device designed as a predetermined breaking point of the coupling element is provided for unfastening the connection between the two connecting elements when a critical load has been exceeded. A stop device is provided for limiting the relative motion of the connecting elements after unfastening of the connection when a critical load has been exceeded.

Abstract: A ventilation device for a building is provided. The ventilation device includes a pair of frame elements spaced a distance from each other to define a free passage extending between an inside of the building and an outside of the building in a clearance defined by the distance. A rotating cylinder is positioned within the clearance and is configured to rotate between a closed position in which the rotating cylinder substantially completely seals the free passage and an opened position in which the rotating cylinder substantially completely opens the free passage. At least two seals are configured to substantially completely seal the rotating cylinder at least at each frame element of the pair of frame elements in the closed position.

Abstract: A composite pane (3) having at least two rigid (glass) plates (3.1, 3.2) and an intermediate layer (33) has flexible holding elements (4) which are positioned in the plane of the intermediate layer between the two rigid plates and extend over their outer edge, for securing the composite pane to a substructure or holding structure (1). According to the invention, flat sections of the holding elements (4) are inserted into corner and/or edge regions of the composite pane (4) and are provided with perforations (4P), and high-strength thin filaments (4F), fibres or woven strands are guided in looped form through or around these perforations (4P), in order thereby to form load-bearing parts of the flexible holding elements (4) which project outward out of the composite.
