Abstract

ELASTIC OUTER PROTECTIVE COVER

in the name of Pascal OREFICE

ABSTRACT OF THE DISCLOSURE

An elastic outer protective cover, is essentially formed from a complex web comprising an elastic textile fibre knitted fabric and a weather-proofing layer heat-sealed on to the knitted fabric. The protective cover also comprises a continuous upper part, flat in the resting condition and of simple shape, having however at least two extensions respectively on two opposite sides, an under part forming pockets beneath said extensions.

Description

~7~ 7 BACKGROUND OF THE INVENTION
l. Field of the Invention The present invention relates to covers enabling the protection of any object, or any space, by isolating it from S the external medium, and which are formed from an extendible material.
More precisely it relates to a protective system which is principally constituted by a web of high strength textile material, having isolating properties and a high, well distributed elastic ratio.
According to the invention, such a protective system is intended particularly for isolating from the external ; medium complex, objects of diverse shapes, the textile material of the cover being such that it can mould itself around different shapes and be held in stretched form on the objects in a particularly simple manner.
2 Description of the Prior Art .

In fact it is already known to protect objects by isolating them from the external medium by a cover which envelopes them. However, currently known protective systems of this type, using principally a woven textile material, have well determined shapes according to the use for which they are intended. It is hence necessary to know exactly the object which it is desired to protect, to take the measurement thereof, and to form a description thereof, to determine the assembly pattern for the different elements which, once cut-out and assembled, will enable the object - to be fitted therewith. The protective cover is therefore in this case the three-dimensional replica of the space of the object to be protected and its formation demands pre-J~?~
, ._.

'7 paratory operations which require time, accuracy and also often pose problems of decomposition of a three-dimensional shape into flat elements capable of providing the shape after assembly. These known covers can only henee serve for the protection of the ~bject alone for which they have been manufactured.
In addition, their use is not always easy. In fact, these covers, manufactured of a flexible but non-elastic material, are 'inert', very difficult to position correctly (formation of folds, of pockets), and it is often necessary to add to them an auxiliary attachment system to make them fast to the object that they protect. For example, a cord and eyelet system, which necessitates, in addition, the provision of corresponding fasteners on the object.
It is an object of the invention to provide a protective cover which overcomes one or more of the above indicated drawbacks.
GENERAL DESCRIPTION OF THE INVENTION
. _ _ _ . _ . . .
According to the invention there is provided a protective system which is formed essentially from a combi-nation of the use of a textile fibre knitted fabric, coated with a waterproofing layer, for the manufacture of a cover and a system for tensioning the latter which consists of providing fastening pockets in the shape itself of the cover to stretch it for use on the object.
Whereas the fabrics currently used are formed of two series of threads interlaced at right angles, composing a practically rigid texture, a knitted fabrie, such as that which is used in the present invention, is distinguished therefrom by the fact that it is formed of a network of interwoven loops, in which a same thread forms a series of loops or meshes. These are generally cloths currently called jerseys. It is known to render such knitted fabrics waterproof by means of a waterproofing layer which is constituted by a film of elastomeric material, of the poly-urethane type for example, which, during the manufacture :

of the web, here of the cover, is glued hot to the knitted fabric. The elastomeric film has an elasticity of the same order of magnitude as that of the knitted fabric and the two surfaces are pressed to one another whilst the whole is heated to a sufficient temperature to cause the surface fusion of the elastomer which is thus fixed to the knitted fabric on cooling.
The application of such a complex web in the pro-tective system according to the invention, enables the production of protective covers of simple shape, and their use to protect objects of complex three-dimensional shapes and of different sizes and volumes, by using the consider-able reserves of elasticity offered by a so constituted cover.
To keep the waterproofed elastic web on the object to be protected, the cover preferably includes pockets formed at the ends adaptable to the projecting portions of the object. Such pockets are formed by a second thickness of web assembled by sewing tothe principal surface which covers the object, the sewing being effected so as to be both elastic and waterproof.
In a preferred case of the use of the invention, the cover is designed to protect pneumatic boats. The same model of the cover according to the invention enables the protection of a whole range of boats of different sizes and shapes where it concerns models having rigid projecting portions corresponding to the position of pockets on the cover.
The invention will now be described more fully with reference to a preferred embodiment for the protection of pneumatic boats. The description refers to the accompanying drawings and is given purely by way of non-limiting illustration.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:

` ~7~537 Figure 1 shows the boat protected by an embodiment of a cover according to the invention, in generally per-spective view Figuxe 2 shows a profile of the embodiment of Figure l;
Figure 3 is a similar view to that of Figure 2, bllt for the boat equipped with its engine;
Figure 4 shows the upper part of the cover in natural position before being placed over the boat;
Figure 5 shows the cover of Figure 4, seen from below; and Figure 6 illustrates a modified embodiment of the cover, seen from below.
DESCRIPTION OF A PREFERRED EMBODIMENT
In the particular case of the embodiment concerned, the cover according to the invention is shaped to serve for the protection of pneumatic boats which comprise essen-tially, like those which are marketed under the trademarks Zodiac and Sillinger, two inflated lateral tubular members 1 and 2 on each side of a central floor 7 meeting to form the bows of the boat.
It is hence seen that such a boat forms three pro-jecting portions which are constituted, on the one hand by the bows 3, and on the other hand by the rear ends or sterns 4, 5, generally conical, of the two tubular members.
The natural shape of the cover, before stretching over the boat, is seen in Figures 4 and 5. The upper part 8 is of simple shape, substantially rectangular, with only three triangular extensions 9, 10 and 11. The first, 9, is located at the middle of a small side of the cover, for the bows of the boat. The two others, 10 and 11, are arranged laterally for the ends of the tubular members.
On the opposite surface (beneath), the cover comprises three portions 12, 13, 14, which cover the extensions 9, 10 and 11. In the modification of Figure 6, the three por-tions are coupled by lateral strips 15 and 16.

:

3l I f q~ 7 The web in which the different parts of the cover are cut out is constituted by a textile fabric knitted from fibres of high elasticity, such as textured artificial fibres. In particular there may be used a jersey which is ; 5 composed of a mixture of polyamide fibres and of fibres of the type denoted by the trademark Lycra, in the proportion of the order of 80% and 20% respectively. In addition to this knitted fabric, the complex web includes a weather-proofing film of an elastomer such as polyurethane resins.
In the manufacture of the web, this film is heat sealed on to the knitted fabric. In another embodiment, the web use-ful for constituting the cover comprises three layers of material: two thicknesses of elastic knitted textile enclosing a waterproofing layer of foam of an elastomer of the type of that sold under the trademark Neoprene or Hypalon.
The various elements cut out from such webs in the shapes of the top 8 and of the three parts of the bottom 12, 13, 14, are assembled together on the periphery of the cover by stitching carried out so as to have substantially the same properties of elasticity and fluid-tightness as the web itself. In general, textured threads are used, in the stitching four chain stitch needles and the water-proofing is effected by glueing by means of an elastic adhesive (with Neoprene, for example). The cover includes in addition reinforcing braids which are stitched on all the unconnected edges, at 17, 18, 19, 20, 21 and 22, in Figure 5~
Figure 4 shows also on the top 8 of the cover, a hole 23 which can be used for the passage of the flag-pole of certain boats. In addition, it illustrates the use of one of the pockets of the cover for its storage. The whole of the cover can be folded and inserted inside the pocket which can then be closed by a system comprising two co-operating strips, one 24 on the top of the cover, seen inFigure 4, the other on the thickness of the under part, not visible in Figure 5.

Naturally the invention is in no way limited to the embodiments which have been described, whether relating to the shape of the cover, the constitution of the web or of the method of assembly. It is capable of numerous modi-fications, the cover being adaptable to numerous uses. Acover for automobiles will include, for example, pockets in the shape of the front and rear bumpers, whilst a military vehicle will not lack projecting portions to which pockets could be fitted designed for this purpose.
