  • a tank may be used as a transportable swimming 2,718,014 9/1955 Mizrach pool. 2,719,982 10/1955 Hasselquist 2,838,768 6/1958 9 Claims, 9 Drawing Figures TRANSPORTABLE TANKS
  • the present invention relates to transportable tanks for example tanks which can be used as swimming pools. More particularly, the invention is concerned with such tanks which are formed by assembling flexible sheet materials and one or more inflatable tubular members which, when the tank contains water, act in the manner of floats and retain its walls in a vertical condition.
  • Tanks of this type which can easily be transported, are practical but, up to now, it has not been known to make them large enough to accommodate several swimmers. Moreover, all those which exist at present are circular; it results therefrom that the area usable at the same time by several swimmers is only a small part of the total available area.
  • French Pat No. 1,454,104 describes a swimming pool made of several tubes of a thermoplasticsweakening of the said swimming pool and would put the user in the difficult position of not being able to use it again.
  • Transportable tanks of this type where the tubes are-formed inthe same manner over their entire length are necessarily circular, even if they are manufactured from materials having a high mechanical resistance.
  • the invention has for an object a transportable tank formed from one or more flexible sheets assembled together with one or more tubes into any desired shape, for example a polygonal shape such as a rectangle, and of any size desired.
  • the invention consists in a transportable tank comprising a base, a wall and at least one inflatable tubular member forming part of said wall, said tank being of polygonal shape, and being braced or supported in the rectilinear parts of said tubular member by flexible members parallel to the axial direction thereof and comprising at least two layers of flexible members, each parallel to the other, the said layers covering the entire periphery of said tubular member and being crossed with respect one to the other, such that their members form with the axial direction of the tubular member equal angles and of opposite direction greater than 55, and said tank being further supported at the corners for the partof the perimeter of the tubular member located externally of the tank by at least two layers of flexible members, each parallel to the other, the said layers being crossed with respect one to the other such that their members make with the axial direction of said tubular member, equal angles and of opposite direction greater than 55, and furthermore wherein that part of the perimeter of said tubular member located inwardly of the tank is supported or braced by at least two layers of flexible members
  • the invention may be used for making rectangular tanks of 13.5 m X 7 m forming a swimming pool with a depth of water of approximately 0.90 m.
  • angles greater than 55 are between 70 and 80 and are advantageously 75 whilst the angles less than 55 are between 45 and 20 and are advantageously
  • FIG. 1 shows a perspective view of a first embodiment of a tank according to the invention
  • FIG. 2 shows a section through any one of the rectilinear parts 1a, 1b, 1c, or 1d ofthe tank ofFlG. 1,
  • FIG. 3 shows a section through any one of the corner parts 1e, 1f, lg or 1h ofthe tank of FIG. 1,
  • FIGS, 4 8 show cross sections through parts of other embodiments of tanks according to the invention.
  • FIG. 9 shows a perspective view of a tank provided with additional supports
  • FIGS. 1-9 show a tank which comprises a continuous tubular member 1 inflatable by means of valves of any known or desired kind. Since such valves are well known in the art, they are not shown.
  • the tank also has side walls 2 and a base'3; as the tank is filled with water, the tubular member 1 acts as a kind of float and pulls the side walls into shape and when the tank is full, retains the walls in an upright position.
  • the rectangular shape of the inflated tubular member I is due to the way it is supported and holds itself. It can be said to be self-supporting or self-bracing.
  • the bracing effect is constituted by an even number of layers shown as 4a and 4b, which layers are arranged one above the other and formed from supple, parallel members such as wire strands or textile, metal or glass cables, crossed in a manner to form with the axial direction equal angles but of opposite direction, greater than 55, preferably between and 80, and usually approximately and from at least one layer of parallel members disposed according to the axial direction of the tubular member, the, said layer covering the entire periphery of the member or only certain areas thereof.
  • the tubular member tends to extend when it is inflated; this has the effect of tightening the members which are parallel to the axial direction, and thus creates a girder effect, which renders the tube rigid in the longitudinal direction.
  • These members parallel to the longitudinal direction extend over the entire length of the rectilinear parts la, 1b, 1c, 1d, but it is not necessary for them to envelop the tube entirely.
  • the tube comprises, in its rectilinear parts, four layers 5a, 5b, 5c and 5d of members parallel to the axial direction.
  • the layers of members parallel to the axial direction may be unequal in.size and may be unequally spaced; their mechanical resistance is'such that they can withstand, without damage, stresses of any normal kind to which they are subjected when the tank is in use.
  • the members may be made from a textile or metal (wires, cables or strands), in any desired. quantity per unit of size and similarly the size of the layer may be selected to fulfil the use to which the tank is to be put.
  • the tubular member is braced or reinforced differently from the rectilinear parts.
  • the support comes from two or any other even number of layers as at 6a and 6b formed on mutually parallel resilient members which are located one above the other and crossed with respect to the axial direction of the tube such that their members make with this latter an angle greater than the equilibrium angle (55), preferably between 70 and and usually approximately 75.
  • these layers are most often identical in their structure and position to those which are used in the rectilinear parts and may form extensions thereof.
  • the armature is also formed from two or any other even number of layers such as 7a and 712, each formed from resilient parallel members which are located one above the other and crossed symmetrically with respect to the axial direction of the tube so that the members of each form with this latter equal angles and of opposite direction but in this case these angles are less than 55", which is the value of the equilibrium angle, and are preferably between 45 and and usually approximately 35.
  • the outer areas 11 wherein the bracing or support members form an angle greater than the equilibrium angle to the direction of the tube axis are extended, whilst the inner areas 12 wherein the angle of the bracing members to the axial direction is less than the equilibrium angle are shortened; thus the parts le, 1f, 13 and 1h ofthe tube are curved to a very short radius.
  • this tube is in fact easy to manufacture by using the manufacturing methods commonly used in the rubber industry.
  • a cord material that is to say a layer of parallel members embedded in a material such as rubber which ensures adhesion of the assembly formed by the different members
  • this cord material may then be cut up into pieces of suitable length and located by juxtaposing them on a sheet of rubber of a size slightly greater than the circumference of the tube, such that the members of the cord material form an angle of between 70 and 80 to the longitudinal direction; on this support layer thus prepared, the other layer may be placed in the same manner but by crossing it with the first symmetrically with respect to the longitudinal direction.
  • the parts corresponding to the zone 12 may then be cut up and removed; assemblies formed from two layers of the same cord material thus superposed and crossed the one with the other symmetrically, may then be placed in the cut-out parts thus made, however, this time, so as to make with the longitudinal direction an angle between 45 and 20; these assemblies slightly overlap the two preceding layers.
  • the longitudinal bracing members intended to reinforce the rectilinear parts of tube may then be positioned (or they could be placed on the first sheet of rubber before the two bracing layers) and a second sheet of rubber may be applied.
  • the tubular member may then be produced by forming a tube which will be obtained by folding the sheet in itself in the longitudinal direction and by causing one end to overlap the other slightly, and finally, by joining the end of this tube.
  • Inflation of the tube imparts the rectangular shape thereto and this shape is maintained: it thus enables rectangular tanks to be produced which preserve their shape when they are full ofwater.
  • tanks according to the invention other means may also be used which have the effect of improving their conditions of use, more particularly when they are deep and of quite large dimensions.
  • At least two reinforcements may be arranged within the tank along the entire length of the rectilinear parts, one being connected to the tube and to the wall and the other being connected to the wall and to the bottom.
  • FIGS. 4 to 8 show different ways of positioning these reinforcements.
  • a reinforcement 8 is fixed to the tube 1 and to the wall 2, and approximately at a third of the height of this latter and a reinforcement 9 is fixed to the wall 2 and to the base 3.
  • the reinforcement 8 prevents the tube 1 from springing partly downwardly when the swimming pool is full of water and this means that the vertical force directed upwardly, exerted by the tube on the wall, is always maximum.
  • the tube 1, being rigid the reinforcement 8 fixes the wall 2 and prevents it from bulging to an exaggerated extent; the reinforcement 9 also retains the wall 2 and prevents bulging thereof.
  • a reinforcement 10 is connected to the tube 1 and to the wall 2 and two reinforcements 11 and 12 are connected to the base 3 and to the wall 2; in the case of FIG. 6, two reinforcements l3 and 14 are connected to the tube 1 and to the wall 2 and one reinforcement 15 is connected to the base 3 and to the wall 2.
  • the wall 2 is thus fixed at two points which also reduce bulging thereof.
  • two reinforcements l6 and 17 are arranged like those of FIG. 4, and moreover another reinforcement 18 directly connects the tube 1 and the base 3.
  • Such a construction has the same effect as the preceding ones and, moreover, securing the tube 1 directly to the base 3, it imparts to the assembly better rigidity.
  • the reinforcements 16 and 17 could be replaced by three reinforcements arranged as in FIG. 5 or 6.
  • two reinforcements 19 and 20 are connected to the tube 1, whilst two other reinforcements 21 and 22 substantially symmetrical to the preceding reinforcements with respect to one wall portion 23 of small height, are connected to the base 3 of the tank.
  • the reinforcement 18 can directly connect the tube 1 to the base 3.
  • All these reinforcements extend over the entirety of the rectilinear parts la, 1b, 1c, 1d and are interrupted in the comer parts 1e, 1f, 1g, 111.
  • the channels which they define with the wall 2, and possibly the tube 1 or the base 3, are open at both ends which enables water to penetrate evenly therein, which is an essential condition in order that filling of the tank is effected under good conditions. It can happen, however, more particularly at the beginning of filling, that the water from the tank penetrates these channels with difficulty. Therefore, if desired in certain constructions, they may be provided with uniformly distributed orifices, as is shown on FIGS. 4 to 7. They can alternatively be made from a cloth having a large mesh or even a net.
  • the support of the rectilinear parts of the tube 1 enables a true girder to be made therefrom, so that it is extremely rigid when inflated.
  • vertical supports such as those shown at 24 in FIGS. 1, 4, 5, 6 and 7 can be arranged from place to place.
  • these supports which can be used as a ladder or as a diving board, are not fixed to the ground but are secured to the base 3 of the tank, due on the one hand to an external part or foot 25, integral with or secured to the base, and on the other hand to a plate 26 to which the part 25 is fixed.
  • the support 24 will continue to maintain the wall in place and prevent all the water contained in the tank from escaping forcefully: they thus form, also, a safeguard.
  • each such support is formed from vertical elements 27 in the shape of beams possibly provided, partially or over their entire length with support plates 28.
  • These beams may on their upper part comprise a protection member, for example rubber, whilst their lower part is placed in a receiving and support socket 29, which is integral with or secured to a plate 30, grooved on its inner face and smooth on its upper face, placed between the ground and the base 3 of the tank; thus, the weight of the water opposite to that of the beam 27 holds the beam upright by reason of the pressure which is exerted thereon.
  • reinforcing grooves 31 and 32, of the retaining plate 20, which means that this latter is separated from the ground enables devices for evacuating and supplying the tank with water to be produced; for example, an orifice 33 is made in the plate 30, and another corresponding orifice is made in the base of the tank, the links between the plate 30 and the base being produced by any sealed means.
  • a transportable tank comprising a base, a wall and at least one inflatable tubular member forming part of said wall, said tank being of polygonal shape, means supporting the rectilinear parts of said tubular member constituted by at least two layers of flexible members parallel to the axial direction of said tubular means and each parallel to each other, the said layers covering the entire periphery of said tubular member and being crossed with respect one to the other, such that their members form with the axial direction of said tubular member equal angles and of opposite direction greater than 55"., and means supporting the corners of said tubular member for the part of the perimeter of said tubular member located externally of the tank, said supporting means being constituted by at least two layers of flexible members, each parallel to the other, the said layers being crossed with respect one to the other such that their members make with the axial direction of said tubular member, equal angles and of opposite direction greater than 55, and furthermore wherein that part of the perimeter of said tubular member located inwardly of the tank is supported by at least two layers of flexible members parallel each to the other,
  • a tank according to claim 1 wherein the longitudinal supporting members situated in said rectilinear parts of the tank are arranged in the inner, lower and external areas thereof.
  • a tank according to claim I wherein reinforcements situated within the tank connect said wall to said tubular members and to said base along said rectilinear parts.
  • a tank according to claim 1 wherein vertical supports are located along the tank, said supports being secured to said base, and disjunct from the ground upon which the tank rests.
  • a tank according to claim 1 wherein supports formed by vertical members are arranged along the tank, said supports being secured to plates located beneath said base of the tank.
  • a tank according to claim 8 wherein at least one of said supports is hollow and used as a means of circulation for water to be contained in the tank, the retaining plate being apertured to communicate with said base of the tank, said base also being apertured to correspond to said apertured retaining plate.
