Magnetic barbegue ignition safety system
Background of the invention
Since barbeque appliances that use propane and/or natural gas as a fuel
source, were
introduced as a means of heating foods, there have always been the unfortunate
possibility of a hazardous situation occurring when operating the appliance.
This is
mainly due scientifically to the fuel + oxygen + ignition = fire and/or
explosion equation.
The measure of hazard is enormously increased if the proper safety procedures
in
operating the appliance are not followed as directed. An extremely important
safety
practice that has the potential for a dangerous hazard occurring if not
followed as
directed, has said to: "Never attempt to ignite the fuel within the barbeque
appliance if
the lid and/or cover is in the closed position." The purpose of this safety
practice is if the
lid and/or cover is in the closed position, and inside the barbeque you have a
proper
gas/air mixture, you have created an enclosed area that when successfully
ignited, the
energy released does not have the proper area for expansion of the rapidly
expanding
energy. The lid and/or cover is now considered the weakest link of
constructing the
enclosed area, and is rapidly and forcefully blown open, again due to the
rapid expansion
of energy created by the fuel + oxygen + ignition = fire and/or explosion
equation. When
this occurs this puts the operator and/or any person(s) surrounding the
hazardous area in
an extremely dangerous environment. Extreme bodily harm and/or death is the
unfortunate possibilities present in these situations. The invention, magnetic
barbeque
ignition safety system, was created to reduce the risks present when operating
a barbeque,
by creating a system in which the operator of the appliance can no longer
successfully
depress and/or rotate the ignition system when the barbeque lid and/or cover
is in the
closed position. Thus eliminating the "ignition" from the fuel + oxygen +
ignition = fire
and/or explosion equation.
Summary of the invention
The purpose of this invention is to prevent the operator of the barbeque
appliance from
depressing and/or rotating the ignition system of the barbeque when the lid
and/or cover
is in the closed position. It can be very dangerous hazardous with natural gas
and/or

propane fueled barbeque systems, if the operator of the appliance is to ignite
the system
when the lid and/or cover is in the closed position. The invention uses a
magnetic field,
created by a magnet, to activate a safety pin located within the ignition
system. This can
be applied to various types of ignition systems as illustrated in the detailed
description
and drawings, including but not limited to electronic ignition, push button
ignition and/or
rotary ignition systems. When the safety pin is activated and is in the
activatedlsafety on
position, the operator of the appliance will not be able to successfully
depress and/or
rotate the ignition system, thus preventing the possibility of a dangerous
hazard from
occurring. As illustrated in further detail in the description of the
invention, the magnet
would be attached to the lid and/or cover of the barbeque. When the barbeque
lid and/or
cover is in the closed position, the magnet would then come into contact with
a magnetic
medium. The magnetic medium would be used to guide to magnetic field created
by the
magnet, to the ignition system where it would draw the safety pin, constructed
of a
magnetic medium material, into an activated/safety on position. When the
barbeque
lid/and or cover would be in the open position, the contact between the magnet
and the
magnetic medium would be broken, and therefore, there would no longer be a
magnetic
field to be guided to the safety pin, and so the safety pin would be released
by the
magnetic field, and the safety pin would fall back into the proper
deactivated/safety off
position.
Detailed description of the invention
Figure I.A.
In Figure 1.A., the barbeque appliance lid and/or cover is in the closed
position and the
safety system is activated. A magnet, seen in Figure l.A.(1), is located on
the lid andlor
cover, that when the lid and/or cover closes, this causes the magnet to make
contact with
contact point, seen in Figure 1.A.(2). The magnetic field created by the
magnet, would
then pass from the magnet, through the contact point, to a wire and/or rod,
seen in Figure
1.A.(3). The magnetic field will the travel though the wire and/or rod, to the
ignition
system, seen in Figure 1.A.(4), which then will activate the safety pin, seen
in Figures
2.A.(1), 3.A.(1), and/or 4.A.(1), that is located within the electronic
ignition, seen in

Figure 2.A., push button ignition, seen in Figure 3.A., and/or rotary ignition
system(s), as
seen in Figure 4.A. The safety pin is now in the activated/safety on position.
Figure 1.B.
In Figure 1.B., the barbeque appliance lid and/or cover, is in the open
position and the
safety system is deactivated. This is due to the magnet, seen in Figure
1.B.(1), which is
no longer in contact with the contact point, seen in Figure l.B.(2), and
therefore breaking
the magnetic field that travels down the wire and/or rod, seen in Figure
l.B.(3), and to the
ignition system(s), seen in Figure 1.B.(4). The safety pin would now be in the
deactivated/safety off position, as seen in Figures 2.B.(1), 3.B.(1) and/or
4.B.(1).
Figure 2.A., Figure 3.A. and/or Figure 4.A
In Figures 2.A., 3.A. and/or 4.A., the safety pin, seen in Figures 2.A.(1),
3.A.(1) and/or
4.A.(1), is in the activated/safety on position. In Figures 2.A., 3.A. and or
4.A., the
barbeque lid and/or cover would be in the closed position as seen in Figure
I.A. The
safety pin is being drawn up towards the attraction point, seen in Figures
2.A.(4), 3.A.(4)
and/or 4.A.(4) by the magnetic field. When the safety pin is in this
activated/safety on
position, the ignition system cannot be successfully depressed andlor rotated
(as in Figure
4.A) by the operator of the appliance, due to the safety pin will come into
contact with
the stopper object, seen in Figures 2.A.(2), 3.A.(2) and/or 4.A.(2).
Fizure 2.B., FiQu.re 3.B. and/or Fi r~ e 4.B.
In Figures 2.B., 3.B. and/or 4.B, the safety pin, seen in Figures 2.B.(1),
3.B.(1) and/or
4.B.(l) is in the deactivated/safety off position. In Figures 2.B., 3.B.
andlor 4.B. the
barbeque lid and/or cover would be in the open position, as seen in Figure
I.B. In this
case the magnet, seen in Figure 1.B.(l), would not longer be in contact with
the contact
point, seen in Figure l.B.(2), and there would no longer be a magnetic field
for the
attraction point, seen in Figures 2.B.(4), 3.B.(4) and or 4.B.(4), to draw the
safety pin,
seen in Figures 2.B.(1), 3.B.(1) and/or 4.B.(1). The safety pin would then,
without being
drawn by the magnetic field, would drop back down into the safety pin guide,
seen in

Figures 2.B.(3), 3.B.(3) and/or 4.B.(3). This would allow the operator of the
appliance to
successfully depress and/or rotate the ignition system.
Figure 1.A.(1), Figure l.B.(1): This object is the magnet (permanent magnet
and/or
electromagnet) which is attached to the lid and/or cover. The magnets purpose
is to create
the magnetic field through the safety system when the lid and/or cover is in
the closed
position.
Figure 1.A.(2), Figure 1.B.(2): This is the contact point which is attached to
the wire
and/or rod, seen in Figure 1.A.(3). The contact point constructed of a
magnetic medium
material (example: iron). The contact point may and/or may not be substituted
by the
wire and/or rod itself, seen in Figures I.A.(3), 1.A.(4). The purpose of the
contact point is
to accept contact from the magnet, seen in Figure l.A.(1), when the barbeque
lid and/or
cover is in the closed position. The contact point is one of the "magnetic
medium(s)". In
the case that the wire and/or rod itself, would substitute the contact point,
the magnet
would come in direct contact with the wire and/or rod when the lid and/or
cover is in the
closed position.
Figures 1.A.(3), 1.B.(3), 2.A.(5), 2.B.(5), 3.A.(5), 3.B.(5), 4.A.(5) and/or
4.B.(5): This
object is the wire and/or rod, that is attached at one end to the contact
point, seen in
Figures 1.A.(2) and/or l.B.(2) and is attached at it's opposite end to the
attraction point,
seen in Figures 2.A.(4), 2.B.(4), 3.A.(4), 3.B.(4), 4.A.(4) and/or 4.B.(4).
The wire and/or
rod is constructed of a magnetic medium material (example: iron). The purpose
of the
wire and/or rod is to guide the magnetic field from the contact point to the
attraction
point, when the barbeque lid and/or cover is in the closed position. The wire
and/or rod is
one of the "magnetic mediums".
Figure 1.A.(4), Figure 1.B.(4): This is the ignition system that will be an
electronic
ignition system, seen in Figure 2.A. and/or Figure 2.B.; push button ignition
system, seen
in Figure 3.A. and/or Figure 3.B.; and/or rotary ignition system, seen in
Figure 4.A.
and/or 4.B.

Figures 2.A.(1), 2.B.(1), 3.A.(1), 3.B.(1), 4.A.(1) and/or 4.B.(1): This
object is the safety
pin, constructed of a magnetic medium material (example: iron). The purpose of
the
safety pin is when the safety pin is in the activated/safety on position, it
is to come into
contact with the stopper object, seen in Figures 2.A.(2), 3.A.(2) and/or
4.A.(2), if the
operator of the barbeque appliance attempts to depress andlor rotate the
ignition system.
The safety pin coming into contact with the stopper object will prohibit the
operator from
successfully depressing and/or rotating the ignition system.
Figures 2.A.(2), 2.B.(2), 3.A.(2), 3.B.(2), 4.A.(2) and/or 4.B.(2): This is
the stopper
object. The purpose of the stopper object is to come into contact with the
safety pin when
the safety pin is in the activated/safety on position, and the operator
attempts to depress
and/or rotate the ignition system. The contact between the safety pin and
stopper object
will prevent the operator from successfully depressing and/or rotating the
ignition system.
Figures 2.A.(3), 2.B.(3), 3.A.(3), 3.B.(3), 4.A.(3) and/or 4.B.(3): This is
the safety pin
guide. The purpose of this safety pin guide is to guide the safety pin into
the safety pins
proper position of operation.
Figures 2.A.(4), 2.B.(4), 3.A.(4), 3.B.(4), 4.A.(4) and/or 4.B.(4): This
object is the
attraction point. It is constructed of a magnetic medium material (example
iron). The
attraction point is one of the "magnetic mediums". The attraction point may
and/or may
not be substituted by the wire and/or rod itself, seen in Figures 2.A.(5),
2.B.(5), 3.A.(5),
3.B.(5), 4.A.(5) and/or 4.B.(5). The purpose of the attraction point, using
the magnetic
field, is to draw the safety pin into the activated/safety on position, when
the barbeque lid
and/or cover is in the closed position. In the case that the wire and/or rod
itself, would
substitute the attraction point, the wire and/or rod itself, using the
magnetic field, would
draw the safety pin into the activated/safety on position, when the barbeque
lid and/or
cover is in the closed position.
