Definitions

  • the present invention relates to personal flotation devices, and more particularly, to self inflating flotation devices stored ont he body of a user.
  • the instant flotation devices attend extremely significant circumstances. Reliable operation is thus of paramount concern, as is the convenience of the article before deployment. In substantially all instances the article accompanies very vigorous physical activity, in an environment vrequently characterized by salt water, sand, and the material deterioration by exposure to sunlight.
  • Yet further objects of the present invention are to provide a releasable flotation assembly which is convenient in fabrication and in use.
  • an elongate split housing including a base cavity hinged at one end to a hollow cover provided with an interior spring clasp at the other end for closure.
  • the clasping end of the base moreover, pivotaly engages an overlying clamping piece which extends over the cover to engage by a springed engagement the pivotal connection of the cover with the base.
  • the clamping piece directs a cantilevered extension against the spring clasp of the cover, releasing its engagement from the base.
  • This same deflection of the clasp by the cantelevered extension of the clamping piece also pierces a seal at the end of a compressed gas bottle stored within the housing and connected to an inflatable bladder folded along the sides thereof.
  • an expedient self actuating flotation assembly which may be worn on the wrist or the waist of a person and which is rendered effective by the simple expedient of releasing a spring clasp. Once this release is made all further steps in the deployment sequence are thereafter self effecting and the user is thus unencumbered with a detail or complicated task during an emergency.
  • the spacing of the housing between which the gas bottle is stored is accuratley dimensioned and the flexure dimension of the clamping piece is geometrically determined by the pivotal geometry of the extension. These geometric constraints are then accomodated in the course of assembly by chamfered pivot stubs in the base.
  • the cover thus may contain, stored as a blister pack, the gas bottle and the collapsed bladder and in this form may be pressed onto the pivot stubs to complete the article.
  • the inventive flotation assembly comprises a hollow split housing 11 including a dished hollow base 12 and a mating, dished, to hollow cover 13. Both the cover and the base are formed to an elongate rectangular planform, each presenting a mating peripheral edge 12a and 13a aligned towards each other. At one end both the cover and the base are releasably hinged to each othe at an exteriorly protruding pivotal pin 15 offset on a web 14 from the cover 13 to present pin ends 15a and 15b for engagement underneath two pivot ears 16a and 16b extending in spaced alignment from the mating portion of base 12. A central segment of the pivot pin 15, shown as segment 15c is thus exposed between the spaced ears 16a and 16b to serve as a latching projection for use described at length hereinbelow.
  • At the opposite end cover 13 is provided with a projecting, substantially rectangular tab 17 extending beyond the plane of edge 13a and formed to a reduced section at the root 17b thereof for resilient bending.
  • both the base and the cover are formed of a polymeric material structure, such as one of the many polymers like polyvinylchloride, polyurethane or one of the polymers in the Nylon group, and thus are characterized by some resiliency and flexure in their structure.
  • Tab 17, consequently, exhibits some flexure in cantilever localized mainly at its reduced section roof 17b and thus may be used as a spring latch to engage the free ends of the base 12 and cover 13 in accordance with the description.
  • the free edge of tab 17 is turned outwardly as a latching ledge 17a. More specifically, to accommodate tab 17 the adjoining edge surface of base 12 is cut away in a conforming cutout 24 which then exposes the surface of tab 17 for inward displacement. Two laterally spaced pivot ears 33a and 33b are then formed on the exterior of edge 12a adjacent the lateral edges of the cut-out 24 for receipt of pin stubs 41a and 41b extending transversely across an orthogonal projection 42 formed on one end of an elongate latching piece generally at 40. Consequently, a portion of the projection 42, shown at 42a, extends radially beyond the pivot axis defined by the pin stubs 41a and 41b to overlie the exposed surface of tab 17.
  • any pivotal motion of piece 40 about this axis will advance the radial portion 42a against tab 17 displacing the tab inwardly.
  • the radial free edge of the portion 42a abuts against a ledge 17a to maintain an interlock and further inward flexure of tab 17 occurs in the course of opening.
  • a compressed gas bottle 50 hermetically sealed to an inflatable bag 51, is received between the interior surface 17c of tab 17 and the opposing interior surface 13c formed within the cover 13.
  • the compressed gas bottle 50 includes an axially moveable cap structure 52 supported by legs 53 against the bottle which, when displaced by the inward flexure of tab 17, will then drive a piercing disc 54 against the bottle end to permit the release of gas into the inflatable bag or bladder 51.
  • This bag or bladder is stored in housing 11, in folded or rolled form, on either side of the bottle 50 until thus expanded.
  • the passage of gas through an orifice is generally determined by the orifice size and the pressure differential thereacross.
  • the inflation of bag 51 is generally an exponential function of an exponent less than 1.
  • the kinematic response of the clamping piece 40 is generally related to the angle of projection 42 around the pivot, a cosine function.
  • the bladder may be tethered against subsequent loss by a line 55 tied to the housing 11 and the housing 11 may, in turn, be affixed to the body of the user by a belt or wrist strap 56.
  • pin stubs 41a and 41b are chamfered at their end surfaces and thus may be manually pressed into engagement between the ears.
