Definitions
- the present invention relates to a novel and useful safety system to aid in boating safety, specifically to avoid carbon monoxide asphyxiation and propellers contacting persons in the water.
- marine engines or motors are often used to operate electrical generators.
- a particular problem arises when a boat , such as a houseboat, idles to permit persons to swim from the rear platform.
- boat operators typically, run gasoline powered generators to feed electricity to air conditioners, entertainment centers, electronic suites, and the like on a boat.
- a cavity between the vessel hull and the swim platform tends to accumulate carbon monoxide, which poses a deadly hazard to swimmers.
- the present invention relates to a novel and useful safety system for a boat .
- the system of the present invention is used with a marine vehicle having a motor and an element movable between a latched and unlatched position for gaining access to the boat.
- a movable element may be a gate, a ladder, a hatch, and the like.
- the boat also includes an ignition circuit for starting the motor, which drives the propeller or electrical generator.
- the motor of the boat may be an inboard or outboard motor.
- the system includes a switch which is normally in a closed position.
- the switch is opened when the movable element travels to the unlatched position. At that point, the switch interrupts the ignition circuit of the motor.
- the movable element must be latched or travel to the latched position before the ignition circuit will permit the motor to run.
- the system of the present invention also includes an override device for the switch.
- the override device includes first connector means and second connector means .
- the first and second connector means are necessarily mechanically and electrically connected by manual mating. Such manual mating bypasses the switch associated with the movable element. Further, the manual disconnecting, or unmating, of the first and second connector means and, in certain cases, the mechanical and electrical connection of a pair of connectors to one another overrides the switch, allowing the ignition system to operate.
- the first and second connector means may comprise first and second connectors having male and female configurations.
- a relay may be mechanically and electrically linked to the switch and the first and second connector means . The battery of the ignition system of the boat would provide the electrical motivation needed to operate the relay.
- the first and second connector means may each include a pair of connectors which must be manually mated to provide the mechanical and electrical linking to the switch, and require the physical unmating and reconnecting to one another to provide such override.
- the override device may be located in a housing, which could be locked or latched in a particular way, preferably with a warning indicia to insure that one overriding the system checks the water in the immediate vicinity of the boat before starting the engine.
- Another object of the present invention is to provide a safety system for a boat which immobilizes the ignition system of the boat when a boat ladder or gate is opened and is not easily overridden by a simple switch, requiring the physical disconnecting and matting of one or more electrical connectors .
- Another object of the present invention is to provide a safety system for a boat which is easily retrofitted to boats and may be employed in multiple locations in the boat .
- a further object of the present invention is to provide a safety system for a boat which immobilizes the ignition system of a boat when a person is in the vicinity of the boat to prevent injuries due to the boat propeller striking the person in the water.
- a further object of the present invention is to provide a safety system which immobilizes the ignition system of a gasoline* powered generator to prevent carbon monoxide generation when the boat is at idle for allowing swimmers to enter the water.
- Another object of the present invention is to provide a safety system for a boat in which it immobilizes the ignition system of a boat that may be overridden if the safety system is damaged in some manner.
- Another object of the present invention is to provide a safety system for a boat which is capable of immobilizing the ignition system of a boat to prevent injuries to persons in the water in the vicinity of the boat which conforms to boats of any size and to boats having a variety of motor types .
- Another object of the present invention is to provide a safety system for a boat to prevent propeller injuries to persons in the water that is relatively low cost to install and maintain.
- Fig. 1 is a schematic view of the safety system of the present invention in a boat having an inboard motor system.
- Fig. 2 is a side view of a movable element of the boat which may be a ladder or a gate .
- Fig. 3 is another schematic of the present invention in an outboard motor system for a boat.
- Fig. 4 is a detail describing the override system of the present invention for an inboard motor.
- Fig. 5 is a detail schematic showing the override system when applied to an outboard motor.
- Fig. 6 is a schematic view of a boat partially in section indicating the generator and accumulation of carbon dioxide .
- the safety system 10 is depicted schematically in Fig. 1 and includes one of its elements switching means 12.
- Switching means 12 encompasses relay 14 and reed switches 16 and 18.
- Switch means 12 is used in conjunction with ignition circuit 20 which propels marine motor 22 having rotating propeller 24 or running a fossil fuel powered electrical generator 66.
- Battery 26 powers ignition system 20.
- An override device 28, illustrated schematically in Fig. 1, is also employed in system 10, and will be discussed in greater detail hereinafter.
- Reed switches 16 and 17 are associated with movable elements on a boat 30, shown partially in Fig. 2, that travel from latched to unlatched positions.
- reed switch 16 is shown in Fig. 2 as being attached to a gate 32 connected to rail 34 by hinge 36.
- Reed switch 16 possesses a permanent magnet 38 which operates reed switch 16.
- reed switch 16 is activated when magnet 38 lies between two and four centimeters therefrom.
- magnet 40 is associated with reed switch 18 in the same manner.
- gate 32 is merely an illustration of a movable element associated with boat 30.
- movable elements in the form of ladders, hatches, portholes, and other items may also be employed in this regard.
- reed switch 16 exists alone, activation of the same is sufficient to permit the operation of ignition switch 42 through the relay 14 which completes the circuit between battery 26 and marine engine 22.
- a plurality of reed switches, such as switches 16 and 18, are employed, all switches must be activated to achieve the same result . That is to say, all gates, ladders, portholes, and the like that are fitted with reed switches, such as reed switch 16, must be closed.
- system 10 of the present invention is also applicable to a marine engine 44 which employs a magneto type ignition, such as those commonly found on an outboard engine .
- a relay 14 is again employed in which reed switches 16 and 18 are similarly installed in boat 30, as is depicted in Fig. 1 and 2.
- Relay 14 is normally closed when reed switches 16 and 18 are closed which would then permit the ignition switch 46 to start engine 44.
- Engine 44 may be cranked manually or through a battery.
- relay 14 grounds or shorts ignition switch 46 preventing switch 46 from starting motor 44.
- This "non- start" configuration is shown in Fig. 3.
- Override device 28 would shunt the connection normally made to relay 14 and permit connection switch to operate in a normal manner.
- relay 14 and override device 28 may take the form of a plurality of manually mated electrical connectors 48.
- Such connectors 48 are found in a housing 50, Fig. 4, preferably in the vicinity of the operator of boat 30.
- Fig. 4 shows a typical override device 28 in which female electrical connector 52 is normally connected to male connector 54.
- female connector 56 is normally connected to male connector 58 to activate relay 14, reed switches 16 and 18, of the safety system 10 hereinbefore described.
- the user may simply install system 10 in an existing ignition circuit 20 with respect to an engine 22 depicted in Fig. 1, which may be an inboard engine, by placing relay 14 in one leg of the ignition circuit 20 associated with ignition switch 42.
- Reed switches 16 and 18 are installed at gates, ladders, latches, and the like in conjunction with permanent magnets 38 and 40 as depicted in Fig. 2.
- the movable elements, such as gate 32 are unlatched, reed switches 16 and 18 remain open breaking the circuit to ignition switch 42 and preventing its operation with respect to marine engine 22.
- relay 14 will close the circuit permitting ignition switch 42 to operate in a normal manner.
- an outboard motor ignition circuit 64 is depicted in which relay 14 and reed switches 16 and 18 operate in a similar manner. Until reed switches 16 and 18 are closed, the marine engine 44 is grounded. The closing of reed switches 16 and 18 remove such ground and permits ignition switch 46 to activate circuit 64, allowing motor 44 to be started by manual cranking or battery means (not shown) .
- Override device 28 would remove the ground associated with relay 14 and permit switch 46 to operate in a normal manner.
- override device 28 consists of manual connectors 48 which must be manually and electrically disconnected, with respect to the embodiment shown in Fig. 5, and reconnected with respect to the embodiments shown in Fig. 4.
- Such manual matable electrical connectors may be kept in a housing 50 for protection and to prevent unauthorized use.
- override device 28 which may, be due to a malfunction of reed switches 16 and 18, the operator of the boat must enter housing 50 disconnect and reconnect, as the case may be, the matable connectors 48, to permit boat 30 to operate.
- This elaborate procedure adds a great degree of safety to the operation of system 10 since a simple override switch is too easily engaged and may cause injury to persons in the water due to propeller strike or carbon monoxide generation.
- Fig. 6 depicts the latter hazard where fuel a powered marine engine 22 runs electrical generator 66 within hull 68 of boat 70.
- Swim platform 72 creates a cavity 74 which tends to accumulate carbon monoxide fumes 76.
- housing 10 may be coupled with indicia to warn the operator of the boat to survey the water in the immediate vicinity of the boat before overriding ignition circuit 20 or 64 through override device 28.
