MARKER AND RECOVERY DEVICE
CROSS REFERENCE
The present application claims priority from US Provisional Application No,
61/493,734 filed June 6, 2011, incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a personal marker and recovery device for
waterbome activities.
DESCRIPTION OF THE PRIOR ART
When engaged in waterbome activities, such as boating, there is a constant risk of
unintentionally falling into the water and being separated from the vessel, To mitigate the risk
of drowning, personal floatation devices (PFDs), otherwise known as life jackets, are in
widespread use and are responsible for saving countless lives from drowning. The PFDs
come in many different configurations but essentially all provide a vest-like structure that fits
over the upper torso. The vest is secured by a harness, in the simplest form tie straps, so that |
the vest is retained on the upper torso. The vest is buoyant and is effective to mamtain the
wearer afloat and face-up in water, |
The vest may be naturally buoyant, such as when made with a closed-cell foam, or |
may be inflatable to achieve the requisite buoyancy, Inflation may come from a small |
pressurized gas cylinder and/or a manual uifllation valve. When properly utilized, the vest is I
capable of supportmg the wearer and mamtaimng them afloat in a stable condition |
indefinitely. ยง
However, although the PFD supports the wearer, the prompt recovery of the
wearer is important due to the exposure to adverse conditions, such as the water temperature
and loss of body heat.
Whilst the vests are made from a high visibility material, such. as a day glow
orange or other fluorescent material, the rescue of the wearer does depend upon the wearer
being visually locatable. in even a relatively small body of calm water, the wearer may not
be readily discernable fi-om the general sun'ounding environment, and, if the wearer is
unconscious, is not able to attract attention to rescuers through waving and/or shouting. This
problem is exacerbated when there is any degree of wave motion and of course the ability to
spot an individual from an aircraft is extremely difficult.
22243033.1
Various proposals have been made to enhance the visibility to facilitate rescue,
US Patent 3,877,096 to Scesney shows an inflatable floatation device that forms a
tetrahedron that can be inflated by a person in distress. This does however require the device
to be inflated by the user and remain tethered to the user once deployed.
US Patent 5,800,227 shows a PFD with a folded marker device on the back of the
PFD. The marker device may be released. This device however is relatively bulky and may
create unbalance such that the face of the wearer is in fact held in to the water rather than
supported above the water.
US Patent 3,638,258 discloses a PFD in which an elongate bar is attached to the
PFD. The bar may be inflated so that a wand is provided that enhances visibility, The wand
is intended to be detachable and therefore its position relative to the wearer may vary,
It is object to the present invention to obviate or mitigate the above disadvantages.
SUMMARY OF THE INVENTION
According to the present invention a marker and recovery device iacludes a body
to be secured to the torso of a wearer. An arch is secured to the body at spaced locations, The
arch is extendable from a stored condition to a deployed condition in which the arch extends
from the torso of the wearer.
Preferably an attachment is provided on the arch approximate the middle of the
arch to facilitate rescue of the wearer.
As a farther preference, the arch in its flaccid state passes behind the head of the
wearer and, upon inflation, moves forward of the head to project normally from the torso of
the wearer.

DETAILED DESCRIPTION OF THE INVENTION
Referring therefore to figure 1, a marker and recovery device is incorporated in to
personal floatation device 10. The device 10 has a body formed as a vest 12 dimensioned to
cover the upper torso ofawearer. It will be appreciated that the vest 12 will be sized
according to the typical dimensions of a wearer and may take many different forms
depending on the intended application and the severity of the envu-omnent in which the PFD
is to be utilized. In the embodiment illustrated m figure 1, the PFD includes a harness
generally indicated at 14 with a buckle 16 to secure the harness around the waist of the
weai'er. Leg loops 18 are also provided to farther secure the vest to the user.
22243033.1 _ 3 -
Other common personal floatation devices do not utilize the leg loops 18 and the
vest 12 may be secured to the torso with simple straps or buckles that pass around the waist
of the wearer.
The vest 12 includes a pair of bladders 20 that are sewn into the material of the
vest. The bladders 20 are connected to a gas cylinder 22 incorporated into the vest 12, The
gas cylinder may be deployed either manually or automatically upon contact with the water to
supply pressurized gas into the bladders 20 and inflate the front facing panels of the vest 12.
Additionally, a manual valve 24 is incorporated on the vest to allow manual inflation of the
bladders ui the event that the pressurized canister 22 fails to inflate the bladders adequately.
A marker and recovery device in the form of an elongate arch, generally indicated
at 30, is secured at spaced locations to the vest 12. The arch 30 comprises a tubular sleeve of
air impermeable material. The opposite ends of the sleeve are secured to the vest, one on
each of the fi'ont panels 13, and are connected to the pressurized canister 22. The connection
to the canister 22 may be through a separate supply line or in directly by connection to the
bladder 20. Alternatively, a separate cylinder, indicated in ghosted outline 26, is provided to
supply the arch 30 with pressurized gas.
The tubular sleeve 32 is made from a flaccid, impermeable material such as
thermoplastic polyurethane (TPU) or PVC coated nylon fabric. In a typical application, the
sleeve 32 has an overall length of between 24 and 48 inches and a diameter of between 2 and
4 inches. Enhanced visibility may be obtained by increasing the length of the sleeve and
arrangements with an overall length of sleeve of 96" and a diameter of 2" have been found to
be viable.
As can be seen more clearly in figures 3 and 4, the sleeve 32 is located on the
front panels 13 and, when stored, is folded back on itself so as to pass behind the head
aperture 15 of the vest 12. Although not shown for the sake of clarity, the sleeve 32 is
preferably covered by a detachable panel or strap so that it is securely stored when not in use
within the body of the vest 12. The detachable panel is a flap of material sewn to the vest 12
with hook and loop fastener, referred to as Velcro, tabs that locate the panel and maintain it in
sitii.
A tab 34 is secured to the sleeve 32 at its midpoint, which coincides with a central
position behind the head of the wearer. The tab 34 has a closed opening 36 that is intended to
receive a hook or rope allowing the wearer of the PFD 10 to be lifted readily from the water,
22243033.1 _ 4 -
As can be seen from figures 3 and 4, prior to deployment, the sleeve 32 is
maintained in a stored condition within the vest 12 and does not interfere with normal
operation of the wearer. If however floatation is requu-ed from the PFD 10, the pressurized
gas 22 is released, causing the bladders 20 to inflate. This may occur prior to immersion in
the water or subsequent to immersion in the water depending upon the particular conditions,
Inflation of the bladders 20 supplies pressurized fluid to the interior of the sleeve
32 causing the arch 30 to begin inflation. Referring to figures 5 and 7, initial inflation of the
arch 30 causes the covering panel to be released and the midpoint of the arch 30 to move
fonvard from behind the head of the wearer. Continued inflation of the arch 30 moves the
arch progressively forward as seen is figure 8 until it attains a deployed condition where it is
fally pressurized and extends normally fi'om the fi'ontpanels of the vest 12. If necessary,
additional mflation can be provided from the manual inflation 24 to ensure that the arch 3 0 is
fally inflated.
When fully inflated, the vest 12 maintains the wearer face-up in the water. In that
position, the arch 30 is projected upwardly and enhances the visibility of the user in the
water. With the typical dimensions of the tube, the mid point of the tube is approximately 24
to 48 inches above the torso of the user which facilitates the identification of the user fi'om a
distance. It will also be noted that the arch 30 does not interfere with the noimal buoyancy
and stability provided by the vest 12 and thereby ensures that the wearer is maintained face-
upward in the water,
Recovery of the user is facilitated by the provision of the tab 34 which enables the
user to be bodily lifted from the water. The tab 34 may be located by a boat hook and a rope
attached to the islet 36. Thereafter the wearer may be hoisted from the water and secured on
board the rescue vessel.
Deflation of the vest 12 similarly causes deflation of the arch 30 allowing it to be
restored for reuse with the vest 12,
Various alternative arrangements may be utilized with the vest 12. The arch 30
may be formed as two separate chambers connected at the tab 34 and inflated separately by
the bladders 20. As noted above, the sleeve 32 may be inflated by a separate gas supply. The
arch 30 may be incorporated ill naturally buoyant PPDs in which case the canister 22 is
provided simply to inflate the sleeve 32. If necessary, a passive inflation device, such as a
22243033.1
foam rubber, coil spring or mechanical linkage could be utilized, but a gas inflation device is
preferred.
The sleeve 32 may be made to be detachable by providing releasable connectors,
such as a zipper, between the sleeve and vest. In this way an existing PFD may be retrofitted
with the arch 30, or the arch 30 replaced if necessary,
An alternative embodiment that may be utilized in combination with an existing
PFD, or on its own where enhanced buoyancy is not required, is shown in figures 10 through
13. Like reference numerals will be used to identify like components with a suffix 'a' added
for clarity.
[0047J In the embodiment of figures 10 through 13, the arch 30a similar in construction
to that described above with respect to figures 1 through 9, is secured to a belt 60 that passes
about the torso of the wearer, The belt 60 is secured about the torso by a buckle 62, which is
adjustable to provide a snug fit about the torso. The belt 60 may be buoyant to provide some
enhanced buoyancy for the wearer, or may be a simple fabric belt when intended for use with
an existing PFD.
The arch 3 Oa is formed from the tubular sleeve 3 2a which, as described above, is
folded back upon itself and passes behind the head of the wearer. Releasable straps 64 hold
the sleeve 32a in place until inflated, The spaced locations at which the arch 30a is secured to
the belt 60 are forward of the aims of the user so that inflation in of the arch 30a extends the
arch and allows it to move forward to a position in advance of the torso. The disposition of
the arch 30a when deployed, as shown in figure 13, is generally normal to the surface of the
water in which the wearer is immersed and so projects upwardly from the water.
A farther embodiment is shown in figures 14 through 16 in which like
components will be identified with a like reference numeral with a suffix 'b' for clarity. In
the embodiment of figures 14 through 16, a belt 60b is utilized, either buoyant or not, and the
arch 3 Ob is secured at spaced locations along the belt. A buckle 62b is provided but located at
the rear of the wearer. The arch 30b is formed from a tube 34b, as described above, which is
folded back on itself along the body of the belt 60b. A detachable flap or strap 64b secures
the tube in 34b the folded condition so as to be constrained within the general envelope
provided by the belt.
22243033.1
A canister for inflating the tube 34b is secured to the belt as indicated at 26b and
upon inflation causes the arch to project forwardly of the wearer. The arrangement shown in
figures 14 through 16 may be combined with a PFD to provide a marker and recovery device
in addition to the buoyancy provided with the PFD.
It will also be appreciated that various fastening devices may be provided for the
vest 12 and that ancillary equipment such as whistles and flashlights may be incorporated mto
the vest 12 as is conventional.
