7 Claims, (Cl. 41-10) It has been proposed to use nettings as camounge material because of their portability and easy storage due to small weight and small bulk. The nettings must be. however, appropriately painted to harmonize with the surroundings. Hence. s plurality of nettings coloured to blend with diierent kinds of surroundings must be kept in stock. standardisation requires, however, the reduction in the colourings to very few types, so that not one of these will be fully satisfactory if actually used in a special case. Besides, the changes of the illumination will innuence differently the colours oi the surroundings and of the camouflage respectively especially if recorded by aerial photography. Hence, no perfect camoufiago can be obtained by means of screens painted in conformity to the locality.

'I'he object of this invention is to provide a single standard camouage structure which will blend with any kind of surrounding or locality independently of the illumination, whether observed directly or ii' photographed from the air. f Another object is to facilitate the erection of the camouflage over compartively large areas.

According to this invention the camouflage comprises three superpoced nets and supporting means to keep a distance between said nets and the object to be camoufiaged, as well as between each net. the lowest net being green and having the smallest meshes, the middle one belng red and having the largest meshes and the uppermost being blue and having meshes of intermediate size.

Referring to the accompanying drawings Figs. 1 and 2 show diagrammatically a sectional eievation and a plan view respectively/of an example of the general arrangement of the camouflage structure according to the invention.

Figs. 8 and 4 show z. diagrammatical sectional elevation and a` plan view respectively of another erecting structure iiigs. and 6 aro ri sectional elevation und a plan view resmctivcig.' of the three supcrposcd nots.

Fig. 'I shows a preferable type of not.

Figs.' ."i and 9 show another example of the erected camouflagev in sectional elevation and a plan view respectively With reference to Fg. 1, I and 2 are the objects to be camouflagcd. la, 3b and 3c are three supenmscd nets shown with dotted lines and suspended on masts 4 which may be of a known telescopatod type.

The nets are manufactured preferably from la is of green colour and has the smallest meshes of about A-i inches. The middle net Ib is red and the width of its meshes is between 2-6 inches, while the uppermost net lc is blue and its meshes are from 2-5 inches wide. The area of the meshes of the middle net should be prefcrably 16 times and that of the uppermost net l2 times the area oi.' the meshes of the lowest net.

The three nets should have preferably the same shape and size but the direction oi. the threads with respect to the outlines of the nets should be preferably different. so that if the nets are duly superposed the threads of the several nets appear in the plan view to intersect each other at acute angles, as will be seen in Fig. 6. The green net la is shown with simple, the red net 3b with double and the blue net 3c with dotted double lines.

As will be seen from Figure 5. thc several nets are kept apart from each other at distances di and d: which should be between 'f-8 inches. The three nets may be connected to each other by connecting links l5 shown in the drawings, of suitable length to secure the distances di and d: respectively.

The catenary suspension shown in Fig. 1 is preferably used in order to keep the nets approximately horizontal and secure the necessary intervels between the nets without increasing too far the tensional stress oi the nets. especially if the span is comparatively large. The catenary suspension is formed by ropes 'I extending below the nets between the masts and props l, which are ilxed between the nets and the ropes 1, to support the several nets. By mean:l oi these props the nets can be even raised towards the centre of the net in the shape of a dome, as shown in Figs. 3 and 4, so that the net can be raised over objects i which are higher than the supporting masts I.

It la desirable tn expose to view a substantial surface of the threads and as large a nsvpcd surface as possible to cause a dlraction of light without increasing the weight of the net. For this purpose instead of knotting the net by single threads, according to Fig. '1, a plurality of com.. paratively thin parallel threads leaving between them narrow gaps are interwoven at the crossings il. At these crossings the position 0i.' the threads is preferably xed by pasting by means of a watertight and non innammable cement such as a phenol-formaldehyde polymerisats varnish or by means of auxiliary threads. Such nets can be woven on suitably combined weaving and rough, piled or nappec threads. The lowest net I6.b0bbll1 100ml.

and crowned by prop structures ii on which the nets are suspended. What We claim is:

1. A camounage comprising three superposed nets and means supporting said nets to keep them apart from each other and the objects to be camoutiaged, the lowest net being green and having the smallest meshes, the middle one being red and having the largest meshes, and thc uppermost being blue with meshes of intermediate size.

2. A camouflage comprising three auperposed nets and means supporting said neta to keep them apart from each other-,and the objezta to be camoutlaged, the lowest net being green and having the smallest meshes, the middle one being rmi and having the largest meshes and the uppermost being blue with meshes oi intermediate size, the nets having the sumo shape and sito but the direction of the threads of the various nets with respect to the outlines of the nets being different.

3. A net for the camouflage according to claim l, in which the threads forming the net. .re composed of a plurality of parallel filaments with narrow gaps between said filaments and interwoven at the crossings.

4. In a camouflage according to claim l, a rope structure spanned underneath the lowest net and props supported by said rope structure and supporting the said net-s.

5. In a camouilage according to claim l, a sup- Porting means for the nets inPuding captive balloons and prop structures on the balloons to which the nets are attached.

6. In a camouflage according to claim l, distoncing members connecting the three nets to each other.

7. In a camouflage according to claim 1, sup porting means for the nets formed by a. ring shaped balloon and prop structures on the balloon to which the nets are attached.
