Definitions

  • the present invention relates to a device by means of which a certain degree of buoymcy can be imparted to machines, and in particular to military road vehicles of the wheel or caterpillar-track type.
  • This arrangement has the disadvantage that it requires the use of masses which are generally cumbersome and in certain cases also vulnerable, notably in connection with military applications.
  • the present invention relates to a device which avoids the above disadvantages while providing various further advantages.
  • a device which comprises at least one surface adapted to be opened out (unfolded) and which is of fluid-tight material, the said surface being connected in fluid-tight manner to the vehicle and delimiting an open chamber at its lower part.
  • the surface adapted to be opened out about the vehicle is connected thereto along a closed curve, all the points of which normally remain out of the Water when the vehicle floats.
  • the surface adapted to be unfolded is connected to the vehicle along a line the two ends of which are normally submerged when the vehicle floats.
  • the inner chamber on the surface adapted to be unfolded is divided into compartments.
  • FIGURE 1 is a diagrammatic view of a vehicle equipped with the device according to the invention.
  • FIGURE 2 is a variant of the device illustrated in FIG- URE 1.
  • the figure shows a vehicle having a surface 2, which is adapted to be unfolded, secured in fluid-tight manner on the body 1.
  • the said surface consists of two portions disposed, in this case, to the right and to the left of the vehicle and secured in fluidtight manner along two lines 3 the end 3a of whichfa single end of each line is visible in the figure) are normally submerged when the vehicle is floating.
  • the surface 2 is water and air tight.
  • a diagrammatic representation is given, with the aid of dot-dash lines 4, of the means permitting the unfolding of the surface 2 and the placing in position thereof so as to float the vehicle.
  • the surface 2 delimits a chamber which is open at its lower portion and closed at its upper portion, due to the fluidtightness of the joint along the lines 3.
  • the air contained within the chamber delimited by the surface 2 is slightly compressed and a dif ference in level h is established between the exterior and the interior of the surface 2. This difference corresponds to the inner pressure of the acting on the inner wall 3,120,832 Patented Feb. 11, 1964 of the surface 2 and also imparts to the vehicle a thrust acting in the upward direction.
  • FIGURE 2 illustrates a variant of the device of FIG- URE 1.
  • the vehicle 5 has, substantially, the contours of a combat car (tank) and a surface 6 adapted to be unfolded is secured to the vehicle in fluid-tight manner, along a closed periphery 7 normally above the water when the vehicle is floating.
  • the surface 6 adapted to be unfolded has then an umbrella shape and may consist for example of an air and water tight fabric secured on ribs shown diagrammatically at 8, and capable of sliding on the said ribs.
  • the surface 6 is folded back and consequently does not in any way hinder the movements of the vehicle and, on the other hand, there is no risk of its being damaged.
  • the surface 6 When the vehicle enters the water, the surface 6 is unfolded and, in the same way as before, a difference of level h is set up between the level within the open chamber delimited by the surface 6 and the exterior of the said surface.
  • the pressure of the air acting on the surface thus contributes to maintaining the vehicle slightly submerged in the water, and permits, where required, the utilization of its means for road propulsion, for the displacement thereof in the water.
  • the invention is not limited to the above embodiments which have been described by way of nonlimitative example; on the contrary, it covers all variants including various devices for the unfolding or opening out of fluid-tight surfaces, either with the aid of jacks or with the aid of belt systems or other known devices; furthermore, the surface adapted to be unfolded itself may comprise any material, which is preferably but not necessarily pliable.
  • the surfaces 2, 6 are in effect walls or wall members.
  • a land based vehicle comprising a mobile chassis having driving means for moving the vehicle on the ground and a fluidtight structure later-ally disposed on said chassis, said fluid-tight structure having a collapsed state in which the structure is collapsed against the chassis and an expanded state in which the structure constitutes at least one skirt flaring outwardly and downwardly of said chassis to define a chamber having a downward facing opening to increase the buoyancy of the vehicle to float the vehicle in a. liquid with the driving means only partially submerged so that the driving means is effective to also at least partially drive the vehicle in the liquid, fsaid vehicle further comprising means for selecting one of said states.
  • a vehicle as. claimed in claim 1 comprising an exhaust on said chassis opening into said chamber.
  • a vehicle as claimed in claim 1 comprising means for supplying a gaseous medium to said chamber.
  • a vehicle comprising a mobile chassis and a fluidtight structure laterally disposed on said chassis, said fluid-tight structure having a collapsed state in which the stwucture is collapsed against the chassis and an expanded state in which the structure constitutes at least one skirt flaring outwardly and downwardly of said chassis, said skirt having a downwardly facing opening and defining an open chamber to increase the buoyancy of the vehicle, said vehicle further comprising means operatively coupled to said fluid-tight structure for selecting one of said states thereof.
  • a vehicle as claimed in claim 6 comprising an exhaust on said chassis opening into said chamber.
  • a vehicle as claimed in claim 6 comprising means for supplying a gaseous medium to said chamber.
