## Title
Buoyancy garment

## Abstract

A clothing item such as a shirt is combined with a concealed and entrapped bladder which can be inflated in the event of an emergency. The shirt can be of fashionable appearance and the buoyance function disguised to make the buoyancy device more attractive to those who otherwise may be inclined to take risks on or in water.

## Background
FIELD OF THE INVENTION
THIS INVENTION relates to buoyancy garments.
BACKGROUND ART
Despite there being many readily available and relatively inexpensive buoyancy aids, accidental death by drowning remains commonplace.
Most buoyancy aids are worn about the chest region of a wearer and most are bulky and very visible.
For some water sport activities such as surfing, kayaking, sailboarding and the like, participants are required to have a high degree of activity and arm freedom in order to participate freely in their activity and bulky or restrictive buoyancy devices are not favoured for this reason.
Another problem in terms of encouraging people to be more water safety conscious which affects young people in particular is the issue of image.
It is very rare to see a board rider wearing a buoyancy device even in treacherous conditions with the obvious conclusion from this that vanity issues are involved.
The more buoyancy devices can be disguised, the more likely they are to be accepted.
There have been numerous proposals for garment-type floatation devices and some proposals for add-on floatation devices worn in association with clothing.
Examples of purpose-built garment-type floatation devices are described in United Kingdom patent no. 2,183,554, U.S. Pat. No. 5,839,933, United Kingdom patent no. 316454 and U.S. Pat. No. 1,428,151.
U.S. Pat. No. 6,231,411 describes a fashionable lifesaving device which, it is said, utilizes the look of casual clothing such as shorts, pants, bathing suits or shirts to disguise inbuilt inflatable chambers.
International patent application no. PCT/AU98/00092 proposes an upper body supporting bladder which can be unobtrusively inserted under a garment such as a wetsuit to provide floatation support in an emergency situation.
It is an object of the present invention to provide a buoyancy device in the form of a common garment with a view to improved water safety.
A further object of the present invention is to provide a buoyancy device which is of fashionable appearance and insofar as is practicable, disguises the fact that it is a buoyancy device.
Further objects and advantages will become apparent from the ensuing description which is given by way of example only.
DISCLOSURE OF INVENTION
According to the present invention, there is provided in combination of a shirt and a floatation device comprising

    
    
        (a) a shirt having a continuous trunk, a collar and arm holes
        (b) a compartment formed from an inner lining or outer overlay which covers the chest and front and rear collar regions of the shirt,
        (c) means for providing access to the interiors of the compartment,
        (d) a removable bladder for insertion into the compartment, and
        (e) means for manual and/or automatic inflation of the bladder to provide floatation support for a wearer of the shirt.
    
    


Access to the compartment is provided by a closable openings positioned about the periphery of same.
The bladder can comprise two separate chest portions communicable with a collar encircling portion.
The collar encircling portion of the bladder can be narrower when viewed in plan than the chest portions.
The front side of the bladder can be provided with a value for manual inflation of the bladder and an actuator for automatic inflation of the bladder via a gas cylinder.
The valve and actuator can be hidden from view by pockets or flanges.
The shirt can be a tee or polo style shirt.
A captured wrap around tensioning device can be positioned just below the compartment.
The tensioning device can be a cord.
The tensioning device can include straps.
The tensioning device can be positioned to coincide with the lower rib region of the wearer.
The tensioning device can be positioned to coincide with the waist region of a wearer.
The closeable opening can be positioned at the rear of the shirt adjacent to the collar region.



BRIEF DESCRIPTION OF THE DRAWINGS
Aspects of the present invention will now be described with reference to the accompanying drawings in which:
FIG. 1 is a front view of a buoyancy garment according to the present invention, and
FIG. 2 is a rear view of the buoyancy garment of FIG. 1, and
FIG. 3 is a plan view of a bladder for the buoyancy garment of FIGS. 1 and 2, and
FIG. 4 is a front view of the garment showing for illustrative purposes the bladder overlaid in the garment, and
FIGS. 5 and 6 are perspective views showing a situation where a wearer may choose to self-inflate the bladder or, when in the water, activate a gas cylinder to achieve inflation.



With respect to the drawings, the buoyancy garment of the present invention comprises a combination of a shirt indicated by arrow 1 and a floatation device in the form of a bladder indicated by arrow 2.
The chest and shoulder region of the shirt provides a compartment 3 into which the bladder can be inserted, the compartment being formed by an inner lining or outer overlay.
In the illustrated example, the compartment is formed from an inner lining.
The garment is provided with an openable and closable opening 4 for inserting and removing the bladder from the compartment.
Other openings may be positioned about the periphery of the compartment.
The opening can be opened or secured with a zip, Velcro, studs or other suitable temporary closure means.
In the illustrated example an opening 4 is provided on the rear face of the shirt and extends between the collar 5 and trunk 6 of the shirt 1.
The bladder 2 and compartment 3 are of complementary shapes so that the bladder snuggly fits into the compartment.
The bladder 2 is provided with two separate chest portions 7 communicable via a neck encircling portion 8.
The bladder 2 is inflatable by inflation means which include a blow tube and one way valve 9 or an inflation gas canister 10 and activating cord 11.
The blow tube and canister are positioned on the chest portions 7 of the bladder to coincide with pocket positions on the shirt.
Tie cords 12 may be provided just below the rib area of the shirt and/or at the bottom hem of the shirt. The tie cords can be threaded into hems of the shirt. Belts may be substituted for the tie cords.
In line with the objectives of the invention to provide a fashionable clothing item which disguises the functional purpose of same, the shirt can be provided with decorative stripes 13 which coincide with the ends of the sleeves of the shirt and/or the hems fixing the underlay to the shirt and defining the outer periphery of the compartment.
The shirt can be made in any suitable fabric or material and in popular styles such as “tees” or “polos”.
The bladder can be manufactured from plastics, UV resistant fabrics, PV coated nylon fabric, or nylon coated neoprene which can be stitched, glued or heat sealed or radio frequency welded.
Pockets or flaps 14 can be provided for disguising the blow tubes and gas inflation devices.
FIGS. 5 and 6 respectively of the drawings illustrate situations in which a user may wish to manually inflate the bladder in situations when unexpected danger occurs such as a large wave or rough seas and then an in-water situation where the user has fallen from a craft and the gas cylinder can be activated.
Because of the configuration of the bladder, the user will be provided with buoyancy support enabling him to either swim or float with the head well clear of water.
There are a number of advantages of the present invention including, inter alia,
(a) the floatation function of the invention can be well disguised as a common place garment,
(b) the bladder can be removed for maintenance and repair and to allow the garment to be separately cleaned,
(c) inflation of the bladder can be achieved orally or in water situations with the assistance of a replaceable gas cylinder,
(d) the invention can be produced at modest cost.
Aspects of the present invention have been described by way of example only and it would be appreciated that modifications and additions thereto can be made without departure from the scope of the invention as defined in the appended claims.
