FR2493504A1 - Camouflage screen mfg. design - garnishing screen with openings and reinforced by nylon or similar type stitching - Google Patents

Abstract

The camouflage screen has a sheet of garnishing, with openings over all its surface reinforced by a network of stitching made with thread strong enough to hold the sheet. This sewing is done by an appropriate multi needled sewing machine. The thread is of nylon, or similar material. The upper and lower threads are chosen to be of the same colour as the face of the garnishing to which they are applied. The network is made up of parallel stitching or this may be in crossed lines or in square patterns.

Description

 Camouflage nets which are used by armies to conceal war material from the enemy are generally made up of sheets of lining reinforced over their entire surface by the net itself.

 The commonly used lining sheets are made of a fabric with synthetic fibers or a plastic material such as polyvinyl chloride, the color of which allows them to be confused with the general color of the environment (green, brown).

 Furthermore, in these filling surfaces, rounded cutouts have been made, in the form of arcs or half-circumferences, etc., intended to give the leaves, when they are placed on the material to be concealed, a relief. giving them the appearance of foliage.

In addition, these lining sheets are made self-extinguishing and they are treated so that their presence is not detected by conventional detection devices (infrared glasses for example),
The net itself is constituted by a large mesh network made of a twisted wire with several strands giving it a very great solidity.

The attachment of this thread to the trim sheet can be done by gluing, by means of clips or by sewing stitches, this latter method of attachment being the subject of French patent application No. 80/12415 of June 4, 1980 on behalf of the BARRACUDA FRANCE Company,
The camouflage nets in accordance with this patent application give all satisfaction, the lining layer being very correctly maintained by the net even with a relatively large spacing between the sewing points,
However, the Applicant, seeking to further improve such camouflage nets, has found a way to limit the weight and the manufacturing cost while retaining the advantage gained from the good maintenance of the lining layer.

This is what is the subject of the present invention,
This in fact consists of a camouflage screen which is essentially characterized by the fact that it consists of a lining sheet reinforced, over its entire surface, by a network of stitches produced using sufficiently strong threads to ensure maintaining this sheet,
The present invention therefore relates to a camouflage net without a net "hence the designation of camouflage screen 2" which lton has chosen to qualify the object of the invention,
The elimination of the net leads to a simplification of the manufacture and a reduction in the cost price, in the calculation of which the price of this net largely entered. In addition, the present invention makes it possible to have a camouflage screen of strength equal to that of known nets for a lower weight, and also of easier handling.

The stitching network which is practiced according to the invention on the conventional filling sheets will advantageously be carried out continuously using an appropriate multi-needle sewing machine, for example of the type described in the application. French Patent No. 2,448,591 (MECA SNC),
The design or pattern of this network of stings may be arbitrary: parallel or even intersecting stitches, for example so as to form a grid.

 A particular embodiment of a camouflage screen according to the present invention will be described in more detail below, by way of indication and in no way limitative, with reference to the single figure of the attached drawing which shows part of this screen. laid flat.

 The camouflage screen shown consists of a lining sheet 1 reinforced by a network of stings 2.

 The sheet I, this green fc or brown glue, is made of a synthetic material such as PVC and it can be reinforced by a network of polyester, polyamide (Nylon), etc.

or by a non-woven layer. It comprises a plurality of rounded cutouts 3 which interpenetrate with each other, so as to form projections when the camouflage screen is put in place, thus giving the appearance of foliage or of a terrain.

 The stitches 2 which crisscross the sheet 1 according to a network of stitches of approximately 5 to 10 cm in side, will be carried out using a solid thread of nylon or the like.

 The different points constituting the stitching 2 have been represented schematically because the detail of their structure will depend on the sewing machine used. The zigzag stitches which are formed at the intersections of the meshes of network 2 are also due to the particular sewing machine which was used for its execution.

 The threads above and below may be chosen in the same color as the face of sheet 1 on which they will be applied.

 It should also be noted that in order to arrive at the result of the invention, which is to consolidate the lining surface 1, it is not essential that the claw stitches are perfectly regular. Besides, the lining sheet with its cuts do not always appear flat in front of the machine needles.

 It is, of course, moreover understood that the embodiment of the camouflage screen according to the present invention which has been described above with reference to the appended drawing has been given for information and is in no way limitative and that modifications can be made without that we depart from the scope of the present invention. It is thus in particular that the classic stitching point which is such that the thread forms a continuous line at the place as upside down could be replaced in an equivalent manner by another point as soon as the desired maintenance of the sheet filling is obtained
