Description
FIELD OF THE INVENTION
The field of art to which the invention pertains includes the field
of buoyant devices, particularly as combined with other life saving
devices, and containers therefore.
BACKGROUND AND SUMMARY OF THE INVENTION
In view of the inherent dangers involved in boating, Coast Guard
regulations require that life preservers of specified types be
carried and a variety of "man overboard" devices are available for
use on boats of all classes. When boating far from shore where high
swells are common, the danger of accidental drowning are increased
by the difficulty of keeping an overboard person in sight in rough
water. As an additional safety precaution boats which are used
under such conditions should carry a float pole (also called a "man
overboard" pole) which is connected to a life buoy and which is
thrown to the man overboard with the life buoy. The float pole is
equipped with a flag which extends several feet out of the water,
aiding location of the buoy. Additionally, particularly for use on
a motorboat, a drogue can be attached to the life buoy to stabilize
the location of the life buoy and prevent it from being dragged
along with the boat. Other devices such as a dye marker, a whistle
and a strobe or flashlight can be connected by lines to the buoy so
that the man overboard can be more readily located.
Thus, for safest operation of a boat under heavy sea conditions, a
conglomeration of safety devices must be assembled and stored for
ready access. However, the number of such devices and their diverse
structures make ready storage and access difficult so that the
greater the number of such devices the longer the period of time
required to get them to a man overboard. The result of attempting
to utilize a plurality of such devices on a fast moving boat is to
often reduce safety as compared to the use of a single device.
The present invention provides a mechanism for assembling a
plurality of life saving devices in a single location and which
provides ready and immediate access to the devices. In particular,
a life buoy and a float pole are releasably secured to a holder
whereby they can be rapidly and substantially simultaneously
released. The holder is in the form of a container for the life
buoy which can be mounted aft of the boat and which includes one or
more springs or the like which are resiliently deformed by
insertion of the life buoy into the container. A lid is provided
closable with the container, to load the life buoy against the
springs, which is provided wit a ready release latch, which may be
a simple pull pin.
The container is formed with a base and defines a rear wall and
side walls upright from the base and a roof whereby to secure the
life buoy upright in the container. The base defines a groove for
sliding engagement with one end of the float pole and the roof
defines a slot whereby the float pole may be secured upright from
the base. In particular embodiments the life buoy is formed with
ends curved in horseshoe manner and a foldable drogue can be stored
between the ends when the life buoy is spring loaded in the
container. The float pole can be disposed anteriorly of the life
buoy so that it is swept outwardly when the life buoy is ejected.
The float pole can be telescopically collapsible and spring loaded
in collapsed form so that upon its release it rapidly expands to
full length.

DETAILED DESCRIPTION
Referring to FIG. 1, there is illustrated one method of mounting
the containerized life saving equipment provided herein. A boat 10
is shown having a housing or container 12 for the life saving
equipment mounted aft of the boat so that the front or ejection end
of the container 12 is the rearward most point of the boat. The
container can be mounted to the guard rail facing rearwardly. A
float pole 14 is shown extending upright from the container 12 and
is telescopically collapsed as will be detailed hereinafter. Other
arrangements for mounting the container 12 will be utilized as
desired as appropriate to the particular boat. The container 12 can
be used with any of the standard commercially available float poles
which are not telescopic and can be mounted at an angle whereby the
flag end of the float pole is contained within a snap-on flag
sleeve to a backstay cable as is presently customary. However, such
additional securement can detract from the ready-release advantages
of the present construction.
Referring to FIG. 2, the components of the containerized assembly
are illustrated. The two major devices which are utilized in
combination to effect the advantages of this invention are a life
buoy 16 and a float pole 14 which is connected to the life buoy by
means of a flexible line 18. The life buoy 16 can be any of the
conventional rigid life buoys constructed of cork or of other light
material. However, certain advantages accrue in the present
invention by utilizing a life buoy having ends 20 and 22 curved in
horseshoe manner as illustrated in that other components, as will
be described, can be stored between the ends 20 and 22. The float
pole or "man overboard" pole can be of conventional design, but in
this embodiment is of collapsible, telescopic construction. The
float pole 14 includes a bottom tubular member 24 to which is
secured toward its top a float 26 of cork or the like having a
plastic or canvass covering to which the line 18 is attached. An
upper tubular member 28, somewhat narrower than the bottom tubular
member 24 and which may be tapered to its top end 30, is
telescopically disposed within the bottom member 24 and is
supported therein by means of a spring, as will be detailed
hereinafter. A flag 32 is carried at the top end 30 of the upper
tubular member 28. For the line 18, one can use 25 feet of 5/16
inch plastic line, or any other convenient line.
In addition to the float pole 14 and life buoy 16, there is also
provided a drogue 34 which is connected to the life buoy 16 by a
pendant 36 of 3 to 5 feet. The drogue 34 is constructed with spring
loaded steel ribs such as at 37 so that it springs open when
released from a folded position.
In addition to the foregoing devices, one may also attach other
life saving devices as desired. For example, a waterproof strobe or
a flashlight 38 can be attached to the life bouy, as illustrated,
by a short pendant 40. Similarly, a whistle 42 and an apertured can
of dye marker 44 can be attached to the bouy 16 by means of lines
46 and 48 respectively. Each of these devices is useful for aiding
the location of a man overboard and their use is well known to
experienced boaters.
In accordance with this invention, a container 12 is provided for
storing the aforedescribed life saving devices in such a manner as
to allow their rapid release. The container 12 includes a base 50,
side walls 52 and 54 secured upright from the base 50 and joining
to form a roof 56, and a rear wall 58 also secured upright from the
base 50 and formed integral with the side walls 52 and 54 and roof
56. A front lid 60 is provided for closing the container 12 and
which is connected by a hinge 62 to the bottom of the base 50. The
side walls 52 and 54, rear wall 58 and lid 60 can be constructed
from fiberglass or other waterproof, durable material. The base 50
can be constructed from teak and is formed with a groove 66
centrally thereof, extending inwardly from its front edge 68, a
distance at least as great as the diameter of the bottom end 70 of
the float pole 14. The groove 66 is sufficiently wide to receive
the float pole end 70 and the roof 56 is formed with a
corresponding slot 72 which is just slightly deeper than the width
of the lower tubular member 24 of the float pole 14. A pin 74 is
formed in the slot 72 for projection into openings 76 and 78 in the
float pole members 24 and 28 respectively when telescopically
collapsed and inserted into the container 12, as will be described.
Coil springs 80 and 82 are secured to the rear wall 58 to extend
outwardly, one on each side thereof, and serve to forcibly eject
the life saving devices. The roof 56 defines a centrally offset
opening 84 for a pull pin whereby the lid 60 can be retained in a
closed position. Teflon washers (not shown) may be inserted in the
openings 76,78 and 84 to aid release. Mounting holes such as at 86
are defined through the rear wall 58 for mounting the container 12
in the manner depicted in FIG. 1. However, other mounting means may
be provided.
Referring now to FIGS. 3 and 4, the manner of mounting and packing
of the container 12 is illustrated. The container 12 is mounted on
a rail 87 by means of a clamp 89 secured by bolts 90 through the
rear wall mounting holes 86. Initially, the drogue 34 is folded and
placed between the ends 20 and 22 of the life buoy 16, along wit
other ancillary devices such as the whistle 42, the dye marker 44
and flashlight 38. The life buoy 16, folded drogue 34 and other
small components are placed in the container 12 and pushed
rearwardly against the springs 80 and 82. The float pole 14 is then
inserted with its bottom end 70 in the base groove 66 and the upper
tubular end 28 is pushed downwardly into the lower tubular member
24 to telescopically collapse the float pole 14. Prior to
collapsing the float pole 14, the flag 32 may be wrapped closely
about the upper end 30 of the upper tubular member 28 so that it
may be slid easily into the lower tubular member 24. As shown in
FIG. 4, a coil spring 88 interconnects the bottom of the tubular
members 24 and 28 so that when the upper tubular member 28 is
inserted into the lower tubular member 28 it is spring loaded
therein and when released is forced to an expanded condition as
illustrated in FIG. 2. Holding the float pole 14 in collapsed
position, with the bottom end 70 thereof inserted in the groove 66,
it is positioned in the roof slot 72 so that the pin 74 projects
into the openings 76 and 78 to thereby secure the float pole 14 in
its collapsed disposition. Following placement of the float pole
14, the lid 60 is raised and closed against the float pole 14. The
side walls 52 and 54 extend somewhat beyond the front edge 68 of
the base 50 so that there is sufficient overlap when the lid 60 is
closed as to allow the insertion of a pull pin 94 through the
offset roof opening 84 to thereby secure the lid 60 in place. The
pull pin is provided with a lanyard 98 which may have a dowel 100
or the like at its free end.
In operation, one need merely pull the lanyard 98 to withdraw the
pull pin 94 from the opening 84, whereupon the force of the springs
80 and 82 immediately throws the lid 60 to an open position and
ejects the contents of the container 12. The float pole 16 and life
buoy are ejected substantially simultaneously carrying the drogue
34 which springs open to prevent the devices from being dragged in
the wake of the boat.
There is thus provided a mechanism for the rapid and substantially
simultaneous release of a plurality of life saving devices. As
required, a detailed illustrative embodiment of the invention has
been disclosed. However, it is to be understood that this
embodiment merely exemplifies the invention which may take many
different forms that are radically different from the embodiment
specifically disclosed. Therefore specific structural and
functional details disclosed herein are not to be interpreted as
limiting, but merely as a basis for the claims which define the
scope of the invention.
