US 11,107,376 B2 · Low drag outdoor media facade display

Abstract

A low drag outdoor media façade display for mounting on a structure susceptible to instability when exposed to strong winds, having an array of radiating elements thinly dispersed about the façade area, held by an array of thin suspension elements, the elements are spaced apart leaving gaps, such that the total surface area of the elements is smaller than the total area of the façade display. A tilting mechanism, active or passive, is operational for tilting the façade display or at least one element thereof. The passive mechanism allows free tilt in response to wind blow, and the elements may include tails. The active mechanism is operational for altering wind load drag profile of the façade display to accommodate wind conditions. The display may be inflatable or collapsible sail-like. A display featuring a liquid spray curtain for refracting or reflecting light projections is a further measure for reducing wind load.

Dependent claims

A low drag outdoor media façade display for mounting on a structure susceptible to instability and tumbledown of said structure when subjected to strong winds and gusts blowing on said façade surface area, said façade display comprising an array of radiating elements and an array of suspension elements,

wherein said array of radiating elements is dispersed about said façade display, said radiating elements are held by said suspension elements, said suspension elements are supported by a frame of said façade display, or by sub-frames of said frame, said radiating elements and said suspension elements are spaced apart leaving gaps, such that said total surface area of said radiating elements, and said suspension elements is smaller than the total area of said façade display, minimizing drag on said façade display;
wherein each of said radiating elements is aerodynamically shaped and configured to rest in a particular positioning in still air and to freely rotate about an axis running therethrough with respect to said façade frame, or the respective sub-frame, on which each of said radiating elements is held when subjected to an incident wind, so as to increase free air passage through the façade display and thereby reduce the drag coefficient of the façade display.

wherein said array of radiating elements is dispersed about said façade display, said radiating elements are held by said suspension elements, said radiating elements and said suspension elements are spaced apart leaving gaps, such that said total surface area of said radiating elements, and said suspension elements is smaller than the total area of said façade display, minimizing the drag of said façade display, and
wherein said active tilting mechanism selectively tilts, with respect to an upright position, in correlation with wind conditions, at least one of:
said façade display, a frame supporting said suspension elements;
sub-frames of said frame;
said suspension elements;
and said radiating elements, said active tilting mechanism comprising a tilt-activator operative to activate the active tilting mechanism in response to and in correlation with the intensity of wind blowing on the façade display, to thereby alter the overall cross-section area facing the wind for altering a wind load drag profile of said façade display to accommodate said intensity of wind.
