Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant(s): MR RICHARD MARK JONES Invention Title: FLOTATION DEVICE The following statement is a full description of this invention, including the best method of performing it known to me/us: 10/06 '04 THU 17:29 FAX 61299255911 GRIFFITH HACK Z014 2 FLOTATION DEVICE Field of the Invention 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.
Background Art 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.
For example, 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.
Despite the availability of buoyancy vests, drowning rates for pe'rsons 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.
o*;oo Other buoyancy aids are available. These include aids to assist a person who is not a competent swimmer or 30 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.
Disclosure of the Invention In accordance with a first aspect, the present *invention provides a flotation device, comprising a o" *oo o* •o COMS ID No: SBMI-00785900 Received by IP Australia: Time 17:39 Date 2004-06-10 10/06 '04 THU 17:29 FAX 61299255911 GRIFFITH HACK Z015 3 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 including a valve enabling the wearer to inflate the flotation means by blowing through the valve, to transfer the flotation means to a buoyant state, and a tag mounted proximate to the valve, and arranged to be pulled by the user when the flotation means is in a non-buoyant deflated state, to remove the flotation means from the carrier member, so that when the wearer pulls the flotation means out of the carrier member by the tag, access to the valve is facilitated.
Preferably, the carrier member and flotation means are separate bodies. In the preferred embodiment the carrier member is a pouch or holder and the flotation means is an inflatable body.
Preferably, 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 the 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.
Preferably, 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 0** 35 flotation means is in the non-buoyant state, with relatively little obstruction.
The carrier member preferably includes attachment *oo ooooo COMS ID No: SBMI-00785900 Received by IP Australia: Time 17:39 Date 2004-06-10 10/06 '04 THU 17:30 FAX 61299255911 GRIFFITH HACK 1016 4 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. Alternatively, the attachment means may be arranged to attach the device to the waist of the user.
Preferably, 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.
Preferably, the flotation means is arranged so that it can be reusable. In a preferred embodiment, the users themselves can inflate the flotation means 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.
In one embodiment, the flotation means comprises a resiliently flexible chamber fillable with a fluid of lower density than water. In a preferred embodiment, 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 30 used in a device adapted to be used by an adult. The air i: 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 S 35 be one-way valve that in normal use prevents escape of air from within the chamber.
*D* oo* ooooo COMS ID No: SBMI-00785900 Received by IP Australia: Time 17:39 Date 2004-06-10 5 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. In one embodiment, 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. In another embodiment, the attachment 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. In one embodiment, the engagement means can comprise a tape having a plurality of small hooks while S* 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.
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 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 10/06 '04 THU 17:30 FAX 61299255911 GRIFFITH HACK 017 6 the flap to its open position.
In an alternative embodiment, the carrier member includes a pouch within which the flotation means can be retained in its non-buoyant state. Where the flotation means comprises a resiliently flexible chamber, it may be folded, in its non-buoyant state, and inserted into the pouch. Preferably the pouch includes drainage means to allow water entering the pouch to drain out. Preferably, 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.
Preferably, the pouch has a flap which covers the pouch opening.
Preferably, 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.
Where there is a connecting means, 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 30 buoyancy.
Preferably, the flotation means is also provided with *an alarm device, which enables the user to give an alarm.
In a preferred embodiment, the alarm is a whistle.

The flotation device 10 incorporates a flotation chamber 14 connected by a length of resiliently flexible cord 15 to carrier member 16. The chamber 14 is formed from an air-tight material and can be filled with air to o:eo 35 so bring it from its collapsed state to its buoyant state when required. In the depicted embodiment, the chamber 14 .oo. has a one-way valve 17 that allows the user 13 to blow air o 0oo.
COMS ID No: SBMI-00785900 Received by IP Australia: Time 17:39 Date 2004-06-10 10/06 '04 THU 17:30 FAX 61299255911 GRIFFITH HACK Z019i 8into the chamber 14 and so bring it to its buoyant state but prevents air escaping from the chamber 14.
The chamber 14, when not in use, is stored in the device in a collapsed state as is depicted in figures 2 and 3. The chamber 14 in the depicted embodiment has a plurality of parallel folds 18 that allow the chamber 14 to be collapsed in a concertina fashion and so occupy a minimum possible volume when not in use (see figure 3).
while the carrier member 16 is shown mounted to an arm 12 in the drawings, it can be mounted to the waist, arm or leg of a user, if desired. The member 16 has two resiliently flexible flaps 19, 21 adapted to each at least partially surround the arm 12. Each flap 19, 21 has a strip of velcro 22 that allows the flaps to be releasably engaged together about the arm 12. A buckle attachment (not shown) may also be included.
When in a collapsed state and not in use, the chamber 14 is held in place on the carrier member 16 by a flap 23.
The flap 23 is movable about a hinge 24 between a closed position (as depicted in figure 2) and an open position (as depicted in figure 3) In the closed position, the flap 23 surrounds the chamber 14 and the cord 15. Once the flap 23 is brought to its open position, the chamber 14 can be readily pulled away from the carrier member 16.
2S The flap 23 has a velcro layer 25 that can engage a complementary velcro layer 25 on the carrier member 16 so ensuring that the flap 22 is held firmly when in its closed position.
The cord 15 is preferably permanently mounted at one end to one end 26 of the flotation chamber 14 and at its other end to the carrier member 16 being mounted to the arm 12 of the user 12.
The device 10 can be worn by users engaged in water sports where the wearing of a normal buoyancy vest is not :35 possible or undesirable. By being mounted to the arm or leg, the device 10 is of a sufficiently small size to allow users to engage in all water activities almost COMS ID Na:SBMI-00785900 Received by IP Australia: Time 17:39 Date 2004-06-10 10/06 '04 THU 17:31 FAX 61299255911 GIFT AKI12 GRIFFITH HACK Z020 9without impediment. The device 10 does, however, provide a level of safety to the user should that person unexpectedly get into difficulties in the water.
In normal use, the user 13 would ensure that the chamber 14 and cord 15 are appropriately stored beneath the flap 23. The user 13 would then mount the device to their arm 10 by wrapping the flaps 19, 21 about their wrist and engaging in the complementary velcro layers 22 together. The user 13 can then enter the water. If they get into difficulty, the user 13 simply has to lift the flap 23 and withdraw the chamber 14. The chamber 14 can then quickly be filled with air by the user 13 blowing through the one-way valve 17. The chamber 14 once filled with sufficient air to support the user 13 can then be allowed to float in the water and held by the user 13 until help arrives or the user 13 manages to reach safety.
Alternatively to the user having to fill the chamber with air themselves, a compressed air canister arrangement may be utilised to automatically expand the chamber 14 on release from the carrier member 16 (as discussed above).
once the user is safe, the device 10 is removed from the arm 12 and, if necessary, the chamber 14 can be deflated and re-stored under flap 23.
In another example of its use, the device 10 can in its closed state be readily carried by a person a lifeguard) swimming to the aid of another in difficulty.
once the lifeguard reaches the person in difficulty, the device can be mounted to that person's wrist or leg and 9 the chamber 14 inflated. The lifeguard can then'readily tow or swim the person to safety.
