BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention refers to a camouflage device in form of foldable irregular dummy objects which are distributed upon and attached to an object to be camouflaged, for preventing identification of the object by the naked eye, optical sensors or computer-aided optical sensors.
Known devices of this kind include support structures with a camouflage netting which can be attached to the military object or which can be tilted to assume the intended position (DE 3501611 A1 and DE 2558371 C2, CH 594867). Although easily identifiable contours of the military object become obscured, the overall dimension of the object to be camouflaged significantly increases. Also, the camouflage netting sags wherever it is not supported, resulting in concave surfaces which do not exist in nature. Whenever these concave surfaces exhibit any gloss (or shimmer), a focusing in focal points at greater distances of the object to be camouflaged can be encountered (in accordance with the principle of a concave mirror). A sagging of larger areas can only slightly be reduced by extending the ends of the support structures of the camouflage netting by means of conventional dish-shaped support elements or by specially designed additional rod assemblies (U.S. Pat. No. 4,441,518). Objects of great dimensions (e.g. trucks or artillery pieces), usually require large areas of same material (camouflage netting) which include further elements like branches, twigs, or the like to achieve a sufficient level of camouflage.
For certain specific objects, like artillery pieces, devices are available that can either cover the artillery piece or be opened to expose it (CH 606972). Such devices yield three-dimensional objects which are enveloped by the camouflage netting; however, since their design is greatly dependent on the regular shape of the military object, the selection of shapes for these camouflage nettings is limited. When opened, this device is less effective for camouflage than in its closed position.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved camouflage device which can be swiftly attached and detached and attains a minimum increase in surface and volume of the military object while yet considerably reducing the visibility thereof.
This object and others which will become apparent hereinafter is attained in accordance with the present invention by providing at least three deformable rod structures, with their one ends joined together, and with their other free ends being adapted for placement upon the object to be camouflaged so as to define an outer frame of irregular three-dimensional curves which is coverable by a camouflage netting to display the envelope and thus the configuration of the object and which is positioned over the corners and edges of the object and has sufficient inherent stiffness or is suitably stiffened through tension in direction towards the placement of the frame. The free ends of the frame are attached to the object at predetermined distances from each other and held in place by friction, strutting or by means of an additional support which is connected to the free ends.
Through the provision of such a frame, the camouflage device can be rapidly and reproducibly assembled and disassembled.
The camouflage device according to the invention permits utilization not only of contrasts of color and brightness, but also of natural shades caused by the dummy objects in the visible spectral range and reflective properties in the other ranges usable for optical purposes (e.g. ultra-violet, infra-red, microwaves, and millimeter waves).
