Definitions

  • This invention relates to a life saving device for saving a person from drowning.
  • a life saving device includes an inflatable body enclosed in a confined space and being in communication with fluid under pressure, and confining means adapted to be located on the wrist or other part of the body and being releasable, release of the confining means causing release of the fluid into the inflatable body.
  • the inflatable body is in the form of an elongated member which is easily grasped and which can be located by the swimmer under the armpits for floatable support in the water.
  • the inflatable body may be attached to the confined space by a line so that on release of the confining means the inflatable body is not carried away.
  • the device may be not much larger than a wrist watch and the confining means may be a lid formation hinged to a base member.
  • the inflatable body may be folded into as small a volume as possible and be connected to a container of compressed fluid, the folded inflatable body and the container being located between the base member and the lid formation.
  • the fluid under pressure is a microcylinder of gas included in the inflatable body and adapted to release its contents on opening the confined space when required.
  • the inflatable body is preferably made from very thin and lightweight and strong material and is preferably a laminate which may include at least one layer of a strong nylon.
  • a pressure switch may be provided which is actuated by a predetermined depth of water and which causes the release of the inflatable body. This is particularly useful for a person who, for example, falls overboard into the sea. At the predetermined depth (which may be about 1 metre) the inflatable body will be released.
  • a one way valve may be additionally or substitutively provided, the valve being actuated by the first contact with the surface of the water in the pool.
  • the device may be incorporated in the arm of a wet suit or other item of swimming apparel.
  • a deflated folded mattress member is also provided and it may be attached to the device of the invention.
  • the swimmer, once supported by the inflatable body is able to inflate the mattress at his leisure for a more permanent and substantial life saving body.
  • a life saving device 10 comprises a hemispherical container 12, in which is housed an elongate inflatable body 14.
  • the container 12 has a base 16 in the form of a housing having air under pressure.
  • An inlet 18 having a valve is located on the outside face of the container 12 while the inside face has an outlet 20 also provided with a valve.
  • the valve for the outlet 20 is connected to a catch mechanism 22.
  • a cover 24 in the form of a hollow dome-shaped body is hingedly connected to the base 16.
  • the inflatable body 14 is in the form of a sausage and in the position seen in Figure 1 is stored in the deflated condition.
  • the body is connected to the air pressure housing through the outlet 20.
  • a length of string 26 connects the body 14 to the container 12.
  • the housing 12 has a wrist band 28 connected at its base.
  • the life saving device 10 is fixed on the wrist of a swimmer.
  • the catch mechanism 22 is manually released. This allows the cover 24 to spring to the open position and simultaneously air from the base 16 is released into the body 14 which immediately inflates and is separated in the fully inflated state from the outlet 20, when inflation is complete.
  • a string 26 restrains the body 14 from moving away from the reach of the swimmer who may grip the body 14 for flotation.
  • a life saving device 30 is made up of a container 32 connected at its base to a wrist band 34.
  • the container 32 is a hollow body having a hinged lid 36 to which is fixed an actuating lever 38. Housed inside the container 32 is a sealed, pressurised gas cylinder 40 enclosed in a deflated body 42. A striker pin 44 is located at the outlet of the gas cylinder 40 and arranged to be moved by the actuating lever 38.
  • the deflated body 42 is attached to the container 32 by a piece of string 45.
  • the lever 38 actuates the striker pin 44 causing gas in the cylinder 40 to be released to inflate the body 42.
  • the cylinder 40 and the striker pin 44 are enclosed inside the inflated body 42.
  • the lever 38 may in other embodiments of the invention (not illustrated) be actuated by water pressure or some other suitable means.
  • the device of the invention may be incorporated in the sleeve or wrist or other suitable position on a wet suit or other garment.
