Shark deterrent gun
Abstract
A tube is constructed of a heavy duty flexible or rigid plastic
or metal and designed for the sealed storage and on demand release
of a liquid or dry fish, animal or reptile repellent. Said tube may
be a specially fabricated device or a standard fire extinguisher or
other common liquid, gas or particle dispenser which can be
incorporated into a lifesaving device such as a life guard rescue
flotation buoy. The tube's predator specific repellent, for example
sodium lauryl sulfate which is a known shark repellent, may be
discharged by the user in the event of an attack by the predator.
The purpose is to expose the predator to an immediate high
concentration of the appropriate repellent thereby diverting the
predator from it's attack.

Description
FIELD OF THE INVENTION
[0001] The present invention pertains to chemically protecting
against sharks or other dangerous sea creatures or land animals and
reptiles that are sensitive to different classes of chemical
deterrents.
BACKGROUND OF THE INVENTION
[0002] To date, my patented means of deterring shark attack for
example is to utilize the arts taught in my existing patents. These
patents are U.S. Pat. Nos. 4,602,384 and 4,917,280 and 4,933,187.
They describe my coated chemical pellets and the various protective
coatings utilized to prolong or prevent the melting of those
chemical pellets. However, at times it is needful to have an
immediate and voluminous blast of chemical to deter or interrupt
shark or other predator attacks. This patent describes such
mechanisms. At present, for example, when life guards attempt the
rescue of a shark attack victim they usually have nothing but a
float device with which to defend themselves should the shark try
to bite them while they are trying to rescue the shark's victim.
With this invented chemical dispensing device housed for example
within their flotation device they could blast a cloud of chemical
repellent at the shark on arriving in the victim's vicinity to
immediately repel the shark from further attacks.
SUMMARY OF THE INVENTION
[0003] It is an object of the present invention to provide, on
demand, a blast of fish, reptile, or animal repellent chemical
emanating from a chemical containment vessel powered by an eruption
of propellant that effects the exit of such chemical from that
chemical containment vessel. The repellent, for example sodium
lauryl sulfate which is a shark repellent, may be housed inside
such a container in a liquid, gel, gas, powder or other dry or
liquid form. When aimed at an attacking creature the device will
shower that creature with repellent chemical to deter its continued
attack.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] FIG. 1 is a side view of the repellent system device shown
as constructed inside the confines of a swimming flotation
device.
[0005] FIG. 2 is a top view of the repellent system device shown
with a pistol grip attached.
[0006] FIG. 3 is a side view of the flotation device showing a fire
extinguisher installed and functionally replacing the repellent
system device as described in FIGS. 1 and 2.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] Referring now to the drawings wherein like reference
characters indicate like parts in the several views, there is shown
in FIG. 1 a side view of the repellent system which shows the
chemical dispensing system installed inside a swimming flotation
device 22 such as those utilized by life guard and coast guard
personnel. This flotation device could be made of foam, cork, wood
or plastic etc. and can have openings formed in its sides to allow
for hand grips 23. This flotation buoy 22 could be of rigid
construction or could be, for example, made of a rubber filled
fabric so it could be of an inflatable design. The repellent
system's tube 12 is internally incorporated into the flotation
buoy. The repellent system tube 12 houses the predator specific
repellent 11, the propulsion mechanism 15, the plastic wadding
sphere 14 and the rope triggering mechanism 16 and 17. Said tube 12
may be manufactured of a heavy duty plastic, either flexible or
rigid, and can be sealed from the outside environment by a blow
away plastic seal 25. This seal is designed to blow away from the
top of the repellent tube by the force of the repellent and wadding
sphere 14 that is being propelled by the propulsion mechanism 15
triggered on demand by triggering mechanism 16 and 17. Other blow
away seals 21 may be utilized internally to form chambers within
the repellent tube 12 which before discharge separates two or more
liquid, gel or dry chemicals. The wadding 14, which is spherical in
shape may be made from a rigid plastic and before the discharge of
the propulsion mechanism 15 it can act as a water tight seal
between said propulsion mechanism 15 and the chemical chamber or
chambers in tube 12. Upon the triggering of the propulsion
mechanism 15 by the activating of the triggering mechanism 16 and
17 the wadding sphere 14 is forcefully propelled through the tube's
chamber or chambers 12 forcing the chemicals housed in the chamber
or chambers through any and all blow away seals 21 and 25 and into
the area in front of the repellent tube. The triggering mechanism
16, a reinforced string, is internally incorporated into the
propulsion mechanism. Said string 16 feeds back through the end cap
of the tube 24 and ends externally into a plastic pull ball 17. To
activate the propulsion mechanism 15 the user grasps the pull ball
17 and applies backward force on the string 16 and thereby
activates the internal propulsion mechanism 15.
[0008] FIG. 2 is a top view of the repellent system device. The
repellent system tube 12 houses the predator specific repellent 11,
the propulsion mechanism 15 the plastic wadding sphere 14 and the
rope triggering mechanism 16 and 17. Said tube 12 may be
manufactured of a heavy duty flexible or rigid plastic or some
metal such as aluminum and can be sealed from the outside
environment by a blow away plastic seal 25. This seal is designed
to blow away from the top of the repellent tube by the force of the
repellent and wadding sphere 14 that is being propelled by the
propulsion mechanism 15 triggered on demand by triggering mechanism
16 and 17. Other blow away seals 21 may be utilized internally to
form chambers within the repellent tube 12 which before discharge
separate two or more liquid, gel or dry chemicals. The wadding 14
which may be spherical in shape may be constructed of a rigid
plastic or other suitable material common to the construction of
such seals and before the discharge of the propulsion mechanism 15,
can act as a water tight seal between said propulsion mechanism 15
and the chemical chamber or chambers in tube 12. Upon the
triggering of propulsion mechanism 15 by the activation of
triggering mechanism 16 and 17, the wadding sphere 14 is forcefully
propelled through tube 12's chamber or chambers forcing chemicals
housed in said chambers through any and all blow away seals 21 and
25 and into the area in front of the repellent tube. The triggering
mechanism 16, a reinforced string, is internally incorporated into
the propulsion mechanism. Said string 16 feeds back through the end
cap of the tube 24 and ends externally into a plastic pull ball 19.
To activate the propulsion mechanism 15 the user grasps the pull
ball 19 and applies backward force on the string 16, thereby
releasing the internal triggering mechanism 17. An extension tube
26 may be fitted to the back end cap 24 of tube 12 to allow for the
installation of a pistol grip 10. This will allow for the user to
maintain better accuracy and control of the repellent tube. A
triggering mechanism 18 and 20 functions as an extension to the
triggering mechanism 16 and 17 with the user grabbing the pull ball
20 and applying backward force to the triggering string 18 thereby
releasing the internal propulsion mechanism 15. String 18 has a
threaded end cap 27 which screws into pull ball 19 to complete the
attachment of the pistol grip.
[0009] FIG. 3 is the same as FIG. 1 but shows a standard fire
extinguisher 30 taking the place functionally of the chemical
dispensing systems described in FIGS. 1 and 2. Such an extinguisher
is an off the shelf item. Quick release 31 allows the extinguisher
to be removed from its mounting on the flotation device 22 so it
can be refilled as necessary. Hand hold openings 23 in flotation
device 22 are the same as in FIG. 1. The nozzle 32 is supplied
repellent by the manual opening of the exit valve using exit valve
handle 33. The repellent charge thus released is directed in the
direction of the shark or other predator. Such fire extinguishers
can expel not only liquid contents but are commonly known to be
capable of expelling dry, granular chemicals or even in some cases
a chemical gel.
[0010] It is obvious that the powered chemical ejection system
described above is only one method of squirting this repellent out
of its container. Another, more simple method would be to make the
container a soft and flexible plastic or other material that could
simply be manually squeezed by hand or by the force of the action
of the waves, etc. to accomplish the ejection of the repellent
contained therein. Such a flexible container could also be mounted
into a life guard's float or into a surf board, etc. and rely on
the user or the waves squeezing out the repellent contents manually
on demand or in a continuous fashion caused by pressure against
such a container's sides caused by the action of the waves for
example.
[0011] It is obvious that the embodiments of this invention could
be successfully effected using many different types of materials
other than those described in this patent. For example, metal may
be substituted for any and all of the plastic materials described
in the patent. Also, the repellent chemical could be in the form of
powders or liquids or a gel. Such a gel for instance could be made
by removing through evaporation much of the liquid water contents
from a liquid such as sodium lauryl sulfate or some other shark or
wild animal repellent liquid as described in this patent and my
other previous patents.
[0012] It is obvious that pressurized air, CO2 or other gas or even
a liquid could be utilized for the necessary propulsion.
[0013] It is also obvious that the repellent used in this repellent
system would be specific to the predator that the system was
intended to be used to repel. For example, sodium lauryl sulfate
for protection against sharks, or cyanne pepper to protect against
bears and other predators such as alligators or crocodiles which
could also be repelled by a mild acid solution that could also be
used.
[0014] It is also obvious that the triggering mechanism and pistol
grip, etc. could be designed differently or in a different shape
than shown and still not depart from the teaching of this
patent.
[0015] It is also obvious that when housed inside a flotation
device said mechanism could be made to be removable from such
flotation device for recharging with more chemical and propellant
after it had been used to discharge its previous load of such
repellent chemicals.
[0016] It is also obvious that this whole system could be built
into other devices other than a life guard's float. Surf boards and
boats or even vehicles, etc. for example, could be designed with
such a repellent dispenser installed.
[0017] It is also obvious that such floats or surf boards, etc.
could also have knives or chemical light emitting containers etc.
installed or otherwise included in their structure for the
emergency use of the victim. Such devices could also be designed
into the repellent dispenser itself for the sake of
convenience.
[0018] It is also obvious that existing mechanisms such as fire
extinguishers could be enlisted to substitute for the repellent
propulsion mechanisms described in FIGS. 1 and 2 above without
voiding or circumventing the intent of the patent. Such fire
extinguishers could be made from plastic or aluminum or other non
corrosive parts if intended for use in sea water.
[0019] It is also obvious that my previously patented chemical
cubes or chemical filled cylinders could also be incorporated into
these designs as adjunct repellent chemical sources.
[0020] It is also obvious that the propulsive force that ejects the
repellent chemicals could be generated in many different ways. Some
of the possibilities are a pressure chamber holding compressed gas
or liquids which when this pressure was released could force the
repellent chemicals out the front of the mechanism. A simple hand
pump is another possible means for ejecting the repellent. Manually
squeezing a soft plastic container until the repellent was ejected
would also be another means of delivering the repellent to the
predator's vicinity. A mixture of chemicals that cause the
generation of a propulsive force of gas etc. when mixed together
could be useful in ejecting the repellent chemicals. Innocent
chemicals like sodium could be stored in separate containers until
used when they would be mixed with water to generate a propulsive
gas for instance.
[0021] It is also obvious that the repellent chemicals might have
greater repellent action if mixed only at the immediate time when
they are being released. More caustic or acid repellent effects
could be available by mixing the necessary ingredients as they were
being ejected.
