Abstract

The flat sign or screen (1) may be shaped as a regular octagon. It is held on pivots (2) so that it may pivot about a horizontal axis when subjected to a high wind loading. The pivots are mounted at the top of vertical frame members (3) mounted on wheels (6) or a foundation fixed in the ground. The sign is normally held in an upright position by permanent magnets (4) on the bottom of the sign and on a crossbar. The screen for back-projection may be made of sand-blasted glass or satin-finish acrylic plastics.

Description

Statische Werbe- oder Rückprojektionstafeln erzeugen im Freien bei Wind eine sehr hohe Flächen­ belastung. Dadurch sind entsprechend starke Verankerungen bzw. Fundamente erforderlich. Die Werbefläche oder Rückprojektionsfläche (1) wird in einem Rahmengestell (3) oberhalb des Schwerpunktes in Schwenklagern (2) aufgehängt und zentriert sich durch das höhere Eigengewicht des unteren Flächenanteils automatisch senkrecht. Diese Basis- und Arbeitsstellung wird durch den Einsatz von berührungslos arbeitenden Permanent-Magnetpaaren (4) stabilisiert. Ab einem bestimmten Winddruck reißt die Magnetkraft ab und die untere Plattenhälfte gibt dem höheren Winddruck nach und schwenkt zu der dem Wind abgelegenen Seite in eine Schräglage. Läßt der Wind nach geht die Fläche automatisch wieder in die durch Magnete stabilisierte Basislage zurück.Static advertising or rear projection boards generate a very high surface load outdoors in the wind. Correspondingly strong anchors or foundations are required. The advertising space or rear projection surface ( 1 ) is suspended in a frame ( 3 ) above the center of gravity in swivel bearings ( 2 ) and is automatically centered vertically due to the higher weight of the lower area. This basic and working position is stabilized by the use of contactless permanent magnet pairs ( 4 ). Above a certain wind pressure, the magnetic force breaks off and the lower half of the plate yields to the higher wind pressure and swivels to the side away from the wind in an inclined position. If the wind blows, the surface automatically returns to the base position stabilized by magnets.

Durch die verstellbaren Schwenklager und einstellbare Magnetspalte kann das System an alle Größen-, Formen- und Umweltbedingungen angepaßt werden. Bei runden Motiven (Rückprojektion System ShopEye mit dem Jörns Werbeprojektor System LogoVision aus Augsburg) empfiehlt sich der Einsatz einer achteckigen Werbe- bzw. Rückprojektionsfläche. Der Winddruck wird schon erheblich gegenüber einer rechteckigen oder quadratischen Form (Bild 1) reduziert und die Lagerung und Magnethalterung kann konstruktiv einfacher ausgeführt werden. Thanks to the adjustable swivel bearings and adjustable magnetic gaps, the system can be adapted to all size, shape and environmental conditions. For round motifs (rear projection System ShopEye with the Jörns advertising projector System LogoVision from Augsburg), the use of an octagonal advertising or rear projection surface is recommended. The wind pressure is already significantly reduced compared to a rectangular or square shape ( Figure 1) and the storage and magnetic holder can be made structurally simpler.
