No. 79,284 Claims priority, application France Jan. 21, 1960 7 Claims. (Cl. 9-400) This invention relates to a new industrial product, and more particularly to flexible buoyant elements which may be assembled into numerous shapes and configurations for the practical purpose of protecting articles such as packages, pipe lines and so on and rendering them buoyant in a liquid.
The elements according to the invention also promote the rapid and economical construction from prefabricated elements of floating works such as rafts, pipes, landing stages, gangways or bridges. The elements may be used individually or in assemblies of appropriate shape and form and are conveniently made in the form of sheets of a desired thickness formed of an impervious and flexible cellular material containing closed cells or by the agglomeration of bubbles or small balloons of natural or synthetic rubber, synthetic plastic or the like.
Where the elements are in the form of sheets, the sheets may be of any desired shape and they are provided internally and/or externally with braids or tapes arranged along, across or diagonally of the sheets so as to form straps or belts having a high tensile strength. They are preferably provided on both faces with a suitable protective covering.
One object of the invention is to provide a method of constructing buoyant elements for attachment to each other and to articles which are to be rendered buoyant.
Another object is to provide means for attach .ient to each other which may be assembled to form a buoyant structure to support a unitary article such as a packing case or continuous objects such as pipe lines, or which may equally readily be assembled together into floating structures such as rafts, bridges or landing stages.
The invention consists of a method of manufacturing a buoyant element comprising the steps of providing a piece of impervious cellular material containing closed cells, attaching thereto lengths of tape or the like, and providing at the ends of the said lengths of tape or the like means for attaching the element to other elements or objects.
The invention includes a method comprising the step of covering the said material and lengths of tape or the like at least partially with a protective covering.
Preferabl the buoyant element is in the form of a sheet which is provided on both faces with lengths of tape, braid, straps or the like formed into loops or other connectible shapes at opposite ends to enable elements to be assembled to each other and to be attached to other articles which are to be rendered buoyant, the sheet and tapes being covered on both faces with a protective outer covering.
Some types of the buoyant elements according to the invention will now be described, by way of example, with reference to the accompanying drawings wherein:
FIGURE 1 shows a rectangular buoyant element seen from above;
FIGURE 2 shows in section a buoyant element provided with a double row of attachments;
FIGURE 3 shows, also in section, an element provided with tapes buried in its thickness;
FIGURE 4 is a plan view of a composite sheet formed of assembled elements;
FIGURE 5 shows superimposed elements fixed together;
buoyant elements having 3,113,328 Patented Dec. 10, 1963 FIGURES 6 and 7 shows two constructional examples of pipe lines rendered buoyant by the attachment of buoyant elements;
FIGURE 8 is a View of a protected and unsinkable packing case; and
FIGURE 9 shows in perspective a floating footbridge or gangway formed by an assembly of buoyant elements.
Referring first to FIGURES 1, 2 and 3, in which like members are given like reference numbers, a buoyant element is formed by one or more sheets 1 made of an impervious cellular material having closed cells, of any desired geometrical shape and of a thickness adequate to support an article which is to be rendered buoyant. The sheets may be made of natural or synthetic rubber or synthetic plastic. A number of lengths of flexible braid or tape 3 are arranged along and across the sheet 1 and attached thereto by glueing, cementing or other means. As shown, the braids or tapes are not parallel to the longitudinal or transverse edges of the sheet 1 but are set at an angle. The braids or tapes are formed into eyes at their ends adjacent the edges of the sheet 1 so that they can be attached one to another. The braids or tapes may be composed of any ribbon-like material with a high tensile strength and they act as supports for the sheets. A sheet of protective fabric 2 is finally placed on each face of the sheet 1 over the braids or tapes 3, which protects the elements from abrasion or other damage. The protective material may be a fabric, or lattice work, or could be formed of slats, and it may be composed of, or impregnated or covered with, a re silient material impervious to water.
The loops 4 are in staggered relationship along any two opposite edges of the sheet by virtue of the angular disposition of the braids or tapes 3, so that: if the edges of two sheets are placed together in alignment the loops on the edge of one sheet fit into the gaps between the loops of the other sheet. It is therefore possible to assemble any number of sheets together by placing rods or the like through the interengaging loops to provide properly aligned assemblies.
If desired the braids or tapes 3 may be placed between sheets of cellular material, as shown in FIGURE 3, the protective covering being laid on the exposed faces of the sheets.
The loops may also be made use of to assemble packs of superimposed elements, as shown in FIGURE 5, where it is desired to increase the total thickness, and therefore the buoyancy, of the elements.
In place of the loops shown, for assembly, such as hooks, may be provided. The loops shown at the ends of the outer elements in FIGURE 5 are differently positioned to those shown in FIGURES 2 and 3 with respect to the thickness of the elen ents 1. The loops may initially be placed in any desired position for producing different assemblies and, since they may be flexible, they may be moved to some extent to enable different elements to be hinged together.
FIGURES 6 and 7 shows how it is possible by the use of the buoyant elements according to the invention to construct rapidly a floating pipe line. In these figures elements shown in previous figures are given like reference numbers. As shown in FIGURE 6, a number of buoyant elements 6 are bent around a pipe 7 and their ends are joined by passing a rod or cable 5 through the loops at the ends, so that the pipe 6 is surrounded by a buoyant covering and provided that the elements are appropriately selected in relation to the weight per unit length of pipe 6 and its contents, the pipe will become buoyant and will float on a liquid, such as water. For supporting a larger pipe 8, two buoyant elements 9, each containing a sheet la of impervious cellular material, are joined together and are wrapped around the pipe,
other members adapted their ends being coupled, so that the two elements are joined at diametrically opposite points by the cables passing through the loops 4. It will be appreciated that for still larger pipes a larger number of elements may be used for each circuit of the pipe. By this particular use of the invention it is possible to produce easily and rapidly, floating pipe lines intended especially for the transfer of petroleum products or the like. The relative displacement of the loops at the two ends, referred to in connection with FIGURE 1, ensures that when the elements are bent around pipes the loops interengage perfectly for coupling together.
FIGURE 8 shows how a plurality of the floating elements, designated 10, may be assembled around a packing case 112 by means of rods or cables 5 connecting the loops 4, so that a floating package is formed. The enclosure of the packing case in the buoyant envelope not only protects the goods in the packing case from shocks in case of accidental impact or dropping, but renders the case unsinkable if it should fall into a liquid element, for example, during shipping or unshipping. it will also be appreciated that floating packages of this kind may be attached to each other to form floating trains which may be towed, for example, for effecting very economical river transport.
As a final example of the utilisation of the invention, buoyant elements which are easily transportable in small bulk may be assembled in situ to form rapidly a floating gangway or bridge, as shown in FIGURE 9. The assembly consists of buoyant elements 13 provided with tapes having loops 4, and outer protective sheets 2, as previously described, assembled together by the rods or cables 5 passing through the loops 4 to form a floating bridge. The elements may be advantageously assembled in such a manner as to form a U-shaped gangway in which the sides serve as parapets. A rope 14 is passed through the upper loops of each of the parapets and acts as a hand-rail to assist users of the bridge in negotiating it.
From the description which has been given it will be evident that many other uses for the floating elements according to the invention may be devised.
