Definitions

  • the present invention relates to a flotation device and in particular to a device that can be readily inflated by a user in an emergency.
  • Flotation devices are often used to improve the buoyancy of persons that engage in activities that might result in that person inadvertently entering the water.
  • buoyancy vests are often worn by sailors while sailing so as to ensure that they have sufficient buoyancy should they inadvertently find themselves in the water.
  • Devices such as life rings are also a common sight on larger vessels and are adapted to be thrown to persons in the water to provide that person with sufficient buoyancy.
  • buoyancy vests Despite the availability of buoyancy vests, drowning rates for persons engaged in water activities are still unacceptably high. Most instances of drowning occur when the person was not wearing a buoyancy vest. This is unsurprising as for many water activities, the wearing of any buoyancy device is too great an inconvenience to the wearer. For example, for a person wishing to bodysurf in a shorebreak, the wearing of a buoyancy vest is unacceptable .
  • buoyancy aids are available. These include aids to assist a person who is not a competent swimmer or who is learning to swim. Such aids include inflatable arm bands . Again, such aids can be an impediment to the enjoyment of water activities and are generally spurned by competent swimmers .
  • the present invention provides a flotation device, comprising a flotation means and a carrier member for the flotation means, the carrier member being attachable to the body of the wearer and being arranged to retain the flotation means in a non-buoyant state, the flotation means being transferable to a buoyant state when required.
  • the carrier member and flotation means are separate bodies .
  • the carrier member is a pouch or holder and the flotation means is an inflatable body.
  • the pouch is made out of soft, flexible material and includes walls forming a receptacle for receiving the flotation means in its non-buoyant state.
  • the pouch includes a flap having a fastening means enabling it to close and open the pouch. The fact that the pouch is soft and flexible renders it easy and comfortable for a user to wear.
  • the present invention preferably provides a device that can be worn by users engaged in water sports where the wearing of a normal buoyancy vest is not possible or undesirable, and which can be brought into use only when required by its wearer.
  • the device is preferably intended for use by a person involved in water sports where the water sport requires that the person gets in to the water in the normal course of the sport eg. swimming, surfing.
  • the flotation device is relatively unobtrusive when the flotation means is in the non-buoyant state.
  • the flotation device is preferably small enough to be attached to and carried by a single limb of the user. The user can therefore preferably swim, at least when the flotation means is in the non-buoyant state, with relatively little obstruction.
  • the carrier member preferably includes attachment means arranged to attach the flotation device to an arm (upper arm, wrist or forearm) or leg of the user.
  • the attachment means may attach to a swimming costume of the user e.g. swimming trunks.
  • the attachment means may be arranged to attach the device to the waist of the user.
  • a connecting means is provided to connect the carrier member to the flotation means, preferably even when the flotation means is in the buoyant state and is in use.
  • the flotation means is arranged so that it can be reusable.
  • the users themselves can inflate the flotation means (e.g. by filling it with air by blowing via a valve) and can deflate the flotation means (via the valve) and return it to the carrier member .
  • the flotation means comprises a resiliently flexible chamber tillable with a fluid of lower density than water.
  • the chamber is air-tight and can be filled with air to so bring it to its buoyant state when required.
  • the chamber can be formed from a polymeric or elastomeric material.
  • the chamber is preferably expandable to a size such that it provides sufficient buoyancy to support an average size adult on the surface of the water. It will be appreciated that different chamber sizes could be utilised in the device depending on the size of the person to be supported by the device. For example, if the device is adapted to be used by a child, the chamber could be smaller than that used in a device adapted to be used by an adult.
  • the air can be provided by a user providing a supply of air at an appropriate pressure to a valve mounted in a wall of the chamber.
  • the user might provide the supply of air by blowing through the valve into the chamber.
  • the valve can be one-way valve that in normal use prevents escape of air from within the chamber.
  • the device can include a chamber filling means.
  • the chamber filling means can comprise a gas supply means mounted with respect to the chamber.
  • the gas supply means can include a tank of compressed gas having a regulator. On activation of the gas supply means, an appropriate amount of gas can be bled from the tank by the regulator into the chamber. Activation can be controlled by an activation means mounted within or outside the chamber.
  • the chamber when not in use, is stored in the device in a collapsed state.
  • the chamber in one embodiment can have a plurality of folds to allow the chamber to be collapsed and so occupy a minimum possible volume.
  • the chamber can have a plurality of parallel folds so allowing the chamber to concertina when changing from its collapsed state to its expanded buoyant state and vice versa.
  • the carrier member can be mounted to the waist of a user.
  • the carrier member can be mountable to a limb of a user, such as a leg or arm.
  • the attachment means can comprise two resiliently flexible flaps adapted to each at least partially surround the limb, with one flap having an engagement means able to engage with a complementary engagement means on the other flap.
  • the engagement means can comprise a tape having a plurality of small hooks while the complementary engagement means comprise a tape having a fibre pile that is engagable by the hooks.
  • An example of such an engagement means is commonly referred to as "velcro" and will be referred to by this name hereafter.
  • the flaps may also include a buckle to provide firmer holding.
  • the flotation means When in a collapsed state and not in use, in one embodiment the flotation means is preferably held in place on the carrier member by a holding means.
  • the holding means can comprise a flap that is movable about a hinge between an open and a closed position. In its closed position, the flap can at least partially surround the flotation means. Once the flap is brought to its open position, the flotation means can preferably be readily pulled away from the attachment member.
  • the holding means preferably has a velcro layer that complements a velcro l layer on the carrier member so ensuring that the flap is held firmly when in its closed position. Where the device incorporates the holding means and a gas supply means, the gas supply means can be activated simply by movement of the flap to its open position.
  • the carrier member includes a pouch within which the flotation means can be retained in its non-buoyant state.
  • the flotation means comprises a resiliently flexible chamber, it may be folded, in its non-buoyant state, and inserted into the pouch.
  • the pouch includes drainage means to allow water entering the pouch to drain out.
  • a tag is provided which extends outwardly of the pouch which can be manipulated by a user to remove the flotation means from the pouch in the event of use being required.
  • the pouch has a flap which covers the pouch opening .
  • the tag is attached to the flotation means so that when the tag is pulled the flotation means is pulled out of the carrier member.
  • the connecting means can comprise a cord formed of a suitable material, such as a fibre, a polymeric material, or an elastomeric material .
  • the cord is preferably permanently mounted at one end to one end of the flotation means and at its other end to the carrier member.
  • the cord is preferably of a sufficient length such that when the device is in use, the flotation means can float on the surface of the water, despite the attachment member being mounted to the arm or the leg of a user.
  • the flotation means when inflated, is preferably substantially cylindrical in shape and can be held between the chest and under arms of a user in order to assist buoyancy.
