Abstract:
1. An anti-bird roosting device for protecting an area, said device comprising: a series of connected cooperating equally spaced apart parallel base elements mounted on the area to be protected; and a plurality of projecting spikes, supported on said cooperating base elements and originating thereon, and projecting away therefrom into a space above the area to be protected, the arrangement of said projecting spikes being such that a first type of said spikes project substantially perpendicular to each of said cooperating base elements and a second type of said spikes are spaced apart and project inwardly from each of said cooperating base elements at various angles and cross one another, such that proximately disposed against a perpendicularly projecting first spike type there is at least one of said inwardly projecting second type spikes originating from another cooperating base element to form a barrier having a symmetrical configuration against bird penetration, acting as an internal defense mechanism and prevent roosting of birds within said protected space, said spikes projecting in a pattern, created by interspersing combinations of vertical, obtuse and acute angle-forming projections, said pattern providing a high spike density which prevents roosting in said protected space, defining a full envelope of protection, wherein said cooperating base elements are spaced apart by a single predetermined width, defining a symmetrical module, and wherein a plurality of said symmetrical modules are provided to allow coverage of a large surface area to be protected, in a single, wide protection envelope without gaps between said plurality of symmetrical modules.
