Definitions

  • the present invention relates to pneumatic life rafts and more particularly to a pneumatic life raft which includes a self-filling ballast of a construction to maximize safety of the raft during deployment and use
  • Life rafts have been well known for many years as useful devices for saving the lives of unfortunate people such as those who crash in an airplane over water or occupants of a ship which may sink or others in situations where drowning might otherwise occur.
  • Known life rafts are normally adequate for their life saving purposes.
  • prior art structures may have a tendency to overturn or fill with water or otherwise fail to fulfil their intended life preserving purpose.
  • Prior art life rafts offer features designed in an attempt to minimize the risk of overturning during turbulent waters. Examples of such prior art structures include U. S. Patent No. 2,390,199 to Walsh. According to that disclosure, a ballast region is provided beneath a life raft but a supplemental valve and hose, operable from within the life raft, must be utilized and operated from within the raft by occupants. The ballast is not self-filling as in the present invention.
  • ballasts are employed but utilize extremely heavy materials for effecting the ballasting function.
  • Such ballast material unduly increases the cost and weight of the life raft.
  • the weight of water in the ballast during normal operation is extremely high, thus, as in the Radnofsky, et al device, exerting a stress on the contact area between the ballast material and the remainder of the raft.
  • the weight is of such magnitude that separation under turbulent seas might be a concern.
  • the excessively large ballast zone requires excess time for filling with water prior to safe utilization of the raft.
  • a ballast is formed beneath and part of a conventional life raft.
  • the ballast is located to extend below the life raft, and upon deployment of the life raft, is automatically filled with the water in which it is floating.
  • a plurality of holes adjacent the bottom of the ballast permits the flow of water into the ballast while a series of holes beneath the water line of the raft, but in the ballast above the first series of holes, permits air to be expelled from the ballast as water enters.
  • the filling of the ballast with water is enhanced and assisted by a pneumatic tube operable upon the pneumatic filling of the life raft to cause the ballast zone to quickly assume the proper orientation as an assist in the filling of the ballast with water.
  • the ballast is of a shape to maximize stabilization with minimum stress on the raft to which it is secured
  • a further object of the present invention is to rapidly ballast pneumatic life rafts in a positive manner with penumatic assistance.
  • Yet a further object of the instant invention is to increase the ballasting efficiency of pneumatic life rafts with a minimum of weight, structure, and force against the life raft itself.
  • FIG. 1 Shown in the figures is the preferred embodiment of the inventive life raft 10.
  • the life raft is seen floating on the water 12 in which is is located.
  • the water line is designated by number 14.
  • a pair of pneumatic rings, upper ring 16 and lower ring 18, are pneumatically separate but physically joined by stitching and adhesives as at 20 to provide the buoyancy for the raft in which survivors of a disaster may find safety.
  • a floor 30 is provided for the raft occupants.
  • the floor is located within the peripheral confines of the pneumatic rings and is constructed of upper and lower layers 32 and 34 of circular shaped, rubberized fabric joined together with stitching in concentric circles sufficiently loose to permit air to flow therethrough and shaped to form concentric rings 40, 42, 44 and 46.
  • Inflation of the floor may be achieved through a supplemental hand pump or the like, acting through a valve 48 in the upper layer 32 whereby inflation of one of the concentric rings 40 will fill the others through a series of interconnecting passageways between the stitching in the . rings.
  • the floor for the raft occupants is constructed so that the outermost of the concentric rings 40 is coupled through adhesives and stitching to the lowermost face of the bottom pneumatic ring 18.
  • the inside of the innermost ring 46 of the support floor 30 is located between and attached by adhesives and stitching to an upper and lower pneumatic tubes 50 and 52.
  • the upper tube 50 is adapted to be inflated through the automatic inflation bottle 22 along with the pneumatic rings 16 and 18.
  • a small tube 54 pneumatically couples the top of the upper tube 50 with the upper pneumatic ring 16 for simultaneous inflation.
  • the upper tube has for its function the supporting of an upper shield 58 adapted to protect occupants from exposure to the elements. This upper shield is provided with doors 60 which the survivors can open through zipper or other appropriate closure means, to permit entry of the survivors into or out of the raft.
  • the lower portion of the upper tube 50 is secured to the floor 30 adjacent the inside of inner ring 46 through adhesives and stitching. Therebeneath is located the upper end of the lower tube 52.
  • the lower tube is of a smaller cross-sectional shape than the upper tube to minimize its buoyancy when in operation inasmuch as it will be positioned beneath the water line.
  • the purpose of the lower tube 52 is to inflate and thereby positively, downwardly expand an inverted cone-shaped ballast 64 located beneath the lowermost segment of the raft.
  • the ballast is coupled to the lowermost portion of the lower pneumatic ring 18 to define the shape of a cone for providing stability to the raft when deployed in the water.
  • Enlarged water entry holes 66 are provided in a circle near the bottom of the ballast to permit the entry of water into the ballast to add weight and stability to the raft.
  • Smaller holes 68 in a circle around the upper periphery of the ballast are provided to permit the escape of air from the ballast zone during inflation with water so that water may be accommodated into the ballast to provide a stabilizing support to the raft while in operation.
  • the low-profile, cross-sectional configuration of the ballast is utilized to maximize the weight of the water adjacent the center of the raft to thereby minimize weight adjacent the edges of the raft for improved stability
  • this particular cross-sectional configuration will hold about 1,200 lbs of sea water and exert a stress of about 15.75 pounds per linear inch along its line of connection with the lowermost pneumatic rings.
  • Greater ballast.weight and stress forces may cause separation of the ballast material from the raft during turbulent water with the result of overturning of the raft.
  • the ballast sheet material, as well as the upper shield material are preferably formed as a series of overlapping and wedge shaped segments extending from the lowermost pneumatic tube inwardly, each toward an apex.
  • the segments are coupled together with conventional adhesives known for firmly holding together the rubberized cloth of which the segments are preferably constructed.
  • supplemental reinforcing sheets 72 and 74 in ring-like configuration are provided adjacent the lowermost portion of the ballast at the apex of the cone. These sheets 72 and 74 will increase the strength at this area of joining.
  • similar reinforcing sheets, also in a ring-like configuration may be provided at the area where the uppermost segment of the lower tube joins the lowermost segment of the upper tube for holding these parts together at the center of the floor 30.
  • FIG. 4 demonstrates the preferred attachment of the pie-shaped ballast fabric segments 80 and 82 adjacent the lowermost portion of the lower tube.
  • the securement of the tube to the apex of the ballast material is achieved through pile fasteners such as velcro.
  • This easily releasable fastener will constitute an area of joining which will separate when it encounters excessive force. This is desirable since this particular segment of the raft receives excessive abuse and force during turbulent weather. Without the releasable coupling, traverse forces could rip these parts apart if they were merely glued and/or stitched to thereby create a hole in the ballast. If such were to occur, the function of the ballast would be lost.
  • FIG. 5 -7 Shown in the Figures 5 -7 is a first alternate embodiment of the inventive life raft.
  • the life raft is seen floating on the water 112 in which is is located.
  • the water line is designated by number 114.
  • a pair of rectangular pneumatic tubes, upper tube 116 and lower tube 118, are pneumatically separate but physically joined by stitching and adhesives as at 120 to provide the buoyancy for the raft in which survivors of a disaster may find safety.
  • the life raft 110 is normally carried in an uninflated condition until need for operation is required. At that time a bottle 122 of a compressed gasseous fluid, such as carbon dioxide, mounted by strap 124 on the lower tube 118 is activated through appropriate valves 126 and 128 to inflate both tubes simultaneously. Regulators of known fashion, operated in the lines and valves may be utilized to insure proper inflation but prohibit underinflation.
  • a compressed gasseous fluid such as carbon dioxide
  • a floor 130 is provided for the raft occupants.
  • the floor is located within the peripheral confines of the pneumatic tubes and is constructed of upper and lower layers 132 and 134 of rectangular shaped, rubberized fabric joined together with stitching sufficiently loose to permit air to flow therethrough and shaped to form adjacent sections 140, 142, 144 and 146.
  • Inflation of the floor may be achieved through a supplemental hand pump or the like, acting through a valve 148 in the upper layer 132 whereby inflation of one of the floor sections 140 will fill the others through a series of interconnecting passag-ways between the stitching in the tubes.
  • the floor for the raft occupants is constructed so that the outermost of the sections 140 and 146 are coupled through adhesives and stitching to the lowermost face of the bottom pneumatic tube 118 along their sides.
  • the front and back of the floor sections are similarly coupled to the front and back of the bottom pneumatic tube, all in an air tight manner.
  • Upper support tubes 150 are pneumatically coupled at each end with the upper tube 116 to be inflated upon the automatic inflation of the pneumatic tube.
  • the purpose of the upper support tubes, of which there are two in number, is to provide support for an upper shield 158 adapted to protect occupants from exposure to the elements.
  • This upper sheild is provided with a least one door 160 which the survivors can open through zippers or other appropriate closure means to permit movement of the survivors into or out of the raft.
  • a plurality of lower support tubes 152, supplemental pneumatic members, are located beneath the lowermost surface of the lower tube 118.
  • Each upper support tube 152 of the plurality extends downwardly and is pneumatically coupled with the lower surface of the bottom tube 118.
  • Preferably one is positioned in each corner of the tube 118 with additional ones in the middle of the sides of the tube.
  • the purpose of the lower support tubes is to inflate with tube 118 and thereby positively, downwardly expand the inverted box shaped ballast 164 located beneath the lowermost segment of the raft.
  • the ballast is coupled with stitching and adhesives to the lowermost portion of the lower pneumatic tube 118 to define the shape of an inverted box for providing stability to the raft when deployed in the water.
  • Enlarged water entry holes 166 are provided in the flat bottom face of the ballast adjacent the periphery to permit the entry of water into the ballast to add weight and stability to the raft.
  • Smaller holes 68 in a plane around the vertically extending upper periphery of the ballast are provided to permit the escape of air from the ballast zone during inflation with water so that water may be accommodated into the ballast to provide a stabilizing support to the raft while in operation.
  • the low-profile, cross-sectional configuration of the ballast is utilized to maximize the weight of the water adjacent the center of the raft to thereby minimize weight adjacent the edges of the raft for improved stability
  • this particular cross-sectional configuration will hold about 2036 lbs of sea water and exert a stress of about 5.96 pounds per linear inch along its line of connection with the lowermost pneumatic tubes. Greater ballast weight and stress forces may cause separ- ation of the ballast material from the raft during turbulent water with the result of overturning of the raft.
  • these raft components are preferably formed as a series of overlapping and tailored segments.
  • the segments are coupled together with conventional adhesives known for firmly holding together the rubberized cloth of which the segments are preferably constructed.
  • FIG. 8 Shown in the Figures 8-10 is the second alternate embodiment of the inventive life raft.
  • the life raft is seen floating on the water 212 in which is is located.
  • the water line is designated by number 214.
  • a pair of pneumatic tubes, upper tube 216 and lower tube 218, are pneumatically separate but physically joined by stitching and adhesives as at 220 to provide the buoyancy for the raft in which survivors of a disaster may find safety.
  • the life raft 210 is normally carried in an uninflated condition until need for operation is required. At that time a bottle 222 of a compressed gasseous fluid, such as carbon dioxide, mounted by strap 224 on the lower tube 218 is activated through appropriate valves 226 and 228 to inflate both tubes simultaneously. Regulators of known fashion, operated in the lines and valves may be utilized to insure proper inflation but prohibit under inflation.
  • a compressed gasseous fluid such as carbon dioxide
  • a floor 230 is provided for the raft occupants.
  • the floor is located within the peripheral confines of the pneumatic rings and is constructed of a single layer 232 of rectangular shaped, rubberized fabric.
  • the floor for the raft occupants is constructed so that the outermost edges are coupled through adhesives and stitching to the region between the uppermost and lowermost faces of the pneumatic tubes 216 and 218 in an air tight manner to preclude water from entering the raft from between the tubes.
  • the floor 230 is constructed of upper and lower layers 232 and 234 of ractangular shaped, rubberized fabric joined together with stitching sufficiently loose to permit air to flow therethrough and shaped to form adjacent sections 240, 242, 244 and 246. Inflation of the floor may be achieved through a supplemental hand pump or the like, acting through a valve 248 in the upper layers 232 whereby inflation of one of the floor sections 240 will fill the others through a series of interconnecting passageways between the stitching in the tubes.
  • Upper support tubes 250 are pneumatically coupled at each end with the upper tube 216 to be inflated upon the automatic inflation of the upper tube 216.
  • the purpose of the upper support tubes 256, of which there are two in number, is to provide support for an upper shield 258 adapted to protect occupants from exposure to the elements.
  • This upper sheild is provided with a least one door 260 which the survivors can open through zippers or other appropriate closure means to permit movement of the survivors into or out of the raft.
  • a single lower support tube 252 is formed in the shape of a V as a supplemental pneumatic member located beneath the lowermost surface of the lower tube 218.
  • Tube 252 extends downwardly at an angle at each end from the sides of lower tube 218 and is pneumatically coupled with the lower surface of the lower tube 218.
  • the ballast zone for receiving water is thus formed between the floor 230, lower tube 218 and sheet material of ballast 264.
  • the purpose of the lower support tube is to inflate with tube 218 and thereby positively, downwardly expand the inverted ballast 264 located beneath the lowermost segment of the raft.
  • the ballast is coupled with stitching and adhesives to the lowermost portion of the upper pneumatic tube 216 to define the shape of an inverted box with a pyramid shaped cross-section for providing stability to the raft when deployed in the water.
  • Enlarged water entry holes 266 are provided in a flat bottom face of the ballast adjacent the periphery to permit the entry of water into the ballast to add weight and stability to the raft.
  • Smaller holes 268 in a plane around the vertically extending upper periphery of the ballast are provided to permit the escape of air from the ballast zone during inflation with water so that water may be accommodated into the ballast to provide a stabilizing support to the raft while in operation.
