Definitions

  • This invention relates to liferafts and more particularly to liferafts configured for use on the high seas and for containing one or more individuals temporary physical support while awaiting rescue upon the high seas. More particularly, this invention relates to liferafts carried aboard vessels and configured for deployment, typically automatic deployment, during an emergency wherein the vessel faces sinking or the imminent threat of sinking.
  • Liferafts for effecting rescue and support of human life on the high seas are well-known. While early liferafts often took the form of a platform formed of lumber, logs or other floatable materials, more recently liferafts have come generally uniformly to be formed from fabric coated on one or both surfaces with a rubberizing compound and formed into a floatation structure.
  • this floatation structure includes one or more circumferential tubes and a floor.
  • the tubes typically are stacked vertically to form a wall of tubes characterized by an uppermost and lowermost tube and the floor typically is cementingly or vulcanizably adhered to the lowermost tube to preclude the entry of water into the liferaft between the floor and the lowermost tube.
  • liferafts typically include an insulation means the better to separate occupants of the raft from cold waters surrounding the raft by more than simply a single ply layer of rubberized fabric. So, modern liferafts typically have a double-walled bottom inflated to provide an insulation capability of where liferafts have a single ply bottom, these liferafts will also include a plurality of insulating floor sections that typically include an insulation pad formed of an insulating material such as foam.
  • Liferafts today may also include a canopy configured to provide a sheltering roof over the raft thereby at least partially protecting occupants of the raft from wind and wave.
  • these canopies include a center support within the raft configured to hold the canopy over the heads of occupants of the raft without the necessity for the occupants jointly raising arms to physically hold the canopy in place above their heads.
  • Liferafts today may also include an inflatable boarding ramp affixed by vulcanization or cementation to an external surface of the raft, functioning to facilitate boarding from deep, open waters.
  • liferafts today typically include at least one ballast means. These ballast means tend to lower the center of gravity of the liferaft and thereby reduce a tendency for the liferaft to tip over and/or tumble during conditions of strong waves and high winds.
  • liferafts It is the custom for liferafts to be formed as an integral unit; that is all, or nearly all of the necessary units of the raft subject to deterioration and/or failure have generally been co-attached permanently so that repair of one or more portions of the raft and its accessories can be quite difficult. Often unrepairable damage to one accessory can render the entire liferaft unuseable necessitating replacement.
  • the present invention provides a modular liferaft.
  • the modular liferaft of the invention includes a hull and floor assembly which comprises a plurality of generally vertically stacked inflatable tubular members defining an outer periphery of the raft, and a floor attached to a lowermost of the inflatable tubular members to preclude entry of water into the raft between the floor and the lowermost tubular member.
  • This floor may be either double-walled to provide an insulation capability or may be configured to accept floor sections configured to provide an insulation capability.
  • These floor sections in the purview of the invention, are removable.
  • a removable canopy is provided.
  • the removable canopy is supported by a separate removable support strut generally centerably positioned within the hull and floor assembly.
  • the support strut typically is an inflatable structure and typically includes a means for inflating this support strut.
  • a boarding ramp is provided for removable attachment to the exterior of the hull and floor assembly.
  • this boarding ramp is an inflatable structure.
  • a ballast means is provided in removably attachable to the hull and floor assembly.
  • the ballast means typically includes a pair of chambers defined by a partition within the ballast means.
  • the canopy and the ballast means are configured for generally peripheral attachment to the hull and floor assembly.
  • the ballast means also may include non-peripheral attachment to the floor such as might be employed to position and support a baffle within the ballast means.
  • the canopy support typically is retained to the hull and floor assembly in removable manner as are the floor sections and the boarding ramp.
  • the canopy typically also is retained in removable manner to the canopy support.
  • Attachment of the canopy, canopy support, floor sections, boarding ramp, and ballast system can be accomplished within and purview of the invention employing reusable fastening means such as snaps, Velcro®, grommets configured to accept ties where the ties are according, webbing straps, or the like, quarter-turn fasteners, and hooks, including swivel hooks, configured to engage grommets or D-rings.
  • reusable fastening means such as snaps, Velcro®, grommets configured to accept ties where the ties are according, webbing straps, or the like, quarter-turn fasteners, and hooks, including swivel hooks, configured to engage grommets or D-rings.
  • the detachable portions of the modular liferaft that is the canopy, canopy support, floor sections if necessary, boarding ramp, and ballast means can be detached from the hull and floor assembly for replacement or repair and the hull and floor assembly can remain in service utilizing replacement accessories during any such necessary service or repair. Further, scrapping of the hull and floor assembly does not necessarily mean scrapping of the accessories, as these may be reused on other raft and hull assemblies.
  • Figure 1 is an exploded view of a modular liferaft made in accordance with the invention.
  • the modular raft 10 includes a hull and floor assembly 12.
  • the hull and floor assembly is comprised of two major elements; one element being a plurality of inflatable tubular members designated in Figure 1 as an upper inflatable tubular member 14 and a lower inflatable tubular member 15, cooperating with a floor element 16.
  • the upper inflatable tubular member 14 and the lower inflatable tubular member 15 are generally positioned vertically one with respect to the next and co-attached typically employing well-known vulcanization or cementation techniques to prevent the passage of water therebetween.
  • the floor 16 and the lower inflatable tubular member 15 are typically co-attached in a similar manner precluding the passage of water therebetween and securing the floor 16 to the tubeless member 15 sufficiently to support loads imposed on the floor by occupants of the modular raft 10.
  • the inflatable tubular members 14, 15 and the floor 16 thereby operate to define a hull and floor assembly 12 or floatation vessel suitable for the containment of chattel goods and human life.
  • the inflatable tubular members 14, 15 may be compartmentalized and function to circumferentially surround the floor to define an open tub or boat-like basin.
