Description

 Vehicle or shuttle for the transport of scuba divers, behaving like a boat on the surface and like a wet submarine when diving.

 The invention relates to a surface boat, behaving as such and which can be used as a submarine, in which the diver is subjected to the ambient environment. This boat or shuttle comprises a nacelle carrying a heat engine used for moving in surface, this nacelle can be freed from the shuttle to enter left on the surface for certain needs.

 In the area of scuba diving, the diver must use a conventional surface boat and then an underwater vehicle to get to the dive site if the distances to be explored are significant.

We know in this area two types of gear;
The first type includes conventional propellants, such as French patent n.1269657 and French patent n.2135968.These vehicles towing or carrying diver divers cannot provide surface navigation.

 The second type includes towed devices such as French patent 1241161,1e French patent 1274168, and the patent ptc / usSl / 7l4.These devices have only quite relative autonomy.

 Divers have so far used two different devices to move during the same dive.

The object of the present invention is to remedy this drawback. The invention as characterized in the claims solves the problem by creating a diving shuttle which can behave on the surface like a fast-moving and unsinkable boat, or as a wet submarine diving
This shuttle is built in reinforced polyester with the shape of a catamaran. The two hulls are used as ballasts and buoyancy boxes.

 On the surface, the shuttle behaves like a boat, the empty and closed ballasts make the boat unsinkable. This type of construction makes it possible to house a boat carrying a heat engine which ensures surface propulsion. outboard engine modified to be contained in a watertight enclosure, it will be equipped with a snorkel, it will drive a small air compressor and a generator of 12 volts. 3 this engine, the shuttle can also navigate in snorkel immersion, by supplying air to the diver.

 To dive the user fills the ballasts with water by opening a valve and an air purge. The shuttle then acquires zero weight, it can then navigate in snorkelling immersion on thermal engine or in deep diving thanks to two electric motors of 12 volts powered by batteries contained in sealed enclosures.

 The shuttle can also be towed from the surface while retaining a certain lateral and vertical autonomy ace thanks to a tow bar, centered vertically on the shuttle, on which a roller positions the attachment point of the trailer to obtain the towing angle more favorable depending on the depth of immersion, thanks to a pneumatic cylinder controlled by ambient pressure. The user can refine the position of the roller by a broom handle.

 This roll bar is moved laterally by the user thanks to a steering wheel placed on the joystick. This roll bar remains in the towing plane but forces the shuttle to pivot around its axis and take the imposed direction.

 The boat's trailer is fixed on a pulley in which slides a rope, the end of which is blocked by a cleat that the user can release in the event of an emergency. The other end of the rope is rung on an automatically disengageable winch as soon as an overvoltage is created on the tow line. The user can act on the disengaging system of the winch to give it the desired sensitivity or block it.

 The shuttle is equipped with two longitudinal floats, placed on each side on the ballasts, incompressible but adjustable in volume and position. These floats allow to adjust the weighing and the longitudinal and lateral attitude.

 The shuttle is equipped with two floating pendulums transversely centered on the center of gravity of the shuttle. These pendulums, controlled by the joystick, allow the shuttle to be tilted from bottom to top, thus facilitating changes in the vertical plane.

 The propellers of the different engines are protected by tunnels which aim to protect divers or swimmers and improve propulsion.

 The propulsion flow coming out of these tunnels is directed laterally and vertically by a system composed of a vertically oriented disc controlled by the steering wheel, this disc drives a disc placed horizontally and controlled by the joystick by means of two forks This system ensuring the lateral and vertical direction of the shuttle.

 According to a variant the thermal propulsion system can be composed by a thermal compressor. This version allowing to obtain a large flow of compressed air which will drive a pneumatic motor placed in the central tunnel. With this version the shuttle must abandon its nacelle on the surface on anchor or take it in tow which will allow it to propel itself with its pneumatic motor. The trailer then acts as an air duct.

 Another variant is obtained by having a receiving well for a conventional outboard motor in the nacelle, this latter also having to be abandoned on the surface.

 The advantages obtained by this invention, consisting essentially of the fact that 1.on a shuttle boat carrying loads that can take away quickly and safely, several divers on the same sites as surface diving and then immersion.

 The invention is set out below in more detail with the aid of drawings representing only one embodiment.

 Figure 12 shows in schematic perspective, the main driving members of the shuttle.

 The figures represent a shuttle for the transport of divers essentially comprising a hull in the form of a polyester catamaran armed with fig t which may have two or four places.6rce has two ballasts 39 located in each float of the cataaaran, this shuttle may be unsinkable or submersible. The shape of this shuttle makes it possible to place behind the passenger cabin, a nacelle 14 in which a heat engine will be housed.

Four versions of nacelles can be placed on the shuttle:
The first version of nacelle fig 3 and fig 4 will be equipped with a modified outboard motor by bringing the propeller base closer to the engine block and by equipping the exhaust outlet with a non-return valve. be done by the propeller hub, or by an exhaust pipe attached to the schnorchel. This heat engine will drive a small air compressor 7 which will supply air to divers under certain conditions, and a generator 8 of 12 volts which will be able to recharge the rechargeable batteries. This engine will be contained in a sealed enclosure of reinforced polyester 6 The propeller will work in a tunnel 13 thus ensuring the protection of swimmers or divers. The heat engine will be supplied with air by a snorkel 5 provided with upper part of a float forming a valve I1, this valve being able to be closed manually by a command 12. In its lower part the snorkel will be equipped with a float valve which will act on an electrical contact 9 which will signal to the user by a warning light any entry of water into the system and which at the same time will stop the engine.The diver will inject pressurized air into the sealed enclosure thanks to a battery of compressed air, which will aim to evacuate the water and to prohibit any new entry. This intervention can be automatic by the action of the electrical contact on a solenoid valve.

 In surface navigation, the shuttle will be powered by this engine, the nacelle remaining on the shuttle.

 In underwater navigation, the shuttle can continue to be propelled by this engine in snorkel immersion, this snorkel can be telescoped to two beings. In these conditions the divers will be able to get air by the engine.

 The nacelle may also be abandoned on the surface in fig 2 and title taken in tow by the shuttle, which will signal the presence of divers and continue to supply air to divers, as well as recharging the wheat batteries. an air hose and a conductive cable.

 The nacelle can also remain on anchor and be reinstated on the shuttle after returning from diving.

 In deep immersion, the nacelle can remain permanently on the shuttle. Propulsion will then be provided by two 12-volt electric motors 26 contained in two 13 propulsion tunnels. These sealed electric motors with 4 forward and 2 reverse speeds. They will be powered by electric batteries 29 contained in sealed containers 28. These containers will be easily interchangeable from the rear of the shuttle.

 The second version of the nacelle 14 fig 7, will be equipped with a high flow compressor 2e, driven by a heat engine 21, a reservoir 19 will regulate the air flow. The propulsion of the shuttle will be provided on the surface by a motor pneumatic placed in the central tunnel. The shuttle nacelle connection will be ensured by a compressed air hose 22. This nacelle cannot be submerged, it will be towed or will remain anchored on the surface. When this nacelle will be towed, it will be able to supply air to the divers , ensure surface or diving propulsion by the pneumatic motor and operate pneumatic tools.

 A third version of nacelle fig 5 and 6, will include a well 17 and an i8 chair. A classic outboard motor 16 will be placed there. This nacelle will remain on the surface in tow or on anchorage. It will only allow surface propulsion.

 A fourth version of the nacelle can be fitted with a heat engine actuating an aerial propeller to propel the shuttle like a hydrofoil. This nacelle cannot be submerged.

 To take the immersion the user will open the filling valves of the 3rd ballasts as well as the air purges. The shuttle will then take a slightly positive zero weighing. If the user cannot take with him the nacelle, he will have to unlock the fixing system, the nacelle will then float on the surface. If the nacelle can be submerged, it will also be filled with water and will remain in place on the shuttle.

 To adjust the weighing, the user will act on a handwheel 33 which will have the action of screwing or unscrewing a sealed cylinder telescoped in another cylinder32 thanks to an internal screw 34.0n will thus vary the weighing as a whole and on each side of the shuttle thus modifying the lateral attitude. By acting on the steering wheel 35, the user will move the two floats 32 which will slide in two cylinders 31 in the longitudinal direction. The attitude will be modified from front to back.

When the user acts on the joystick 3, the float pendulum provided with an incompressible float 36 and a ballast 37 will tilt via a chain 38. The shuttle will then tend to pivot around the pendulum axis, aided by the displacement of the center of gravity due to the displacement of the float 36 and the ballast in opposite directions
By its action on the joystick 3 the chain 38 and the chain 53 tilt the discs 23 via the forks 25, thereby directing the propulsion flow up or down, propelling the shuttle in the opposite direction .

 By acting on the steering wheel 3, the cables 51 and 52 will rotate the discs 24 from right to left to move the shuttle laterally.

 In the event of a disaster, the user by acting on the handle 39 will release the two weighted pads 4, the lightened shuttle from the front will initiate an upward movement, the mortises in the pads 4 will be released, the pads released, the shuttle taking a positive weighing will initiate an ascent.

 The user by injecting compressed air into the 3rd ballasts, will transform the shuttle into a surface boat. This function can be used in immersion to raise heavy loads to the surface.

 The shuttle can also be fitted with a diving towing system, which consists of a roll bar 1 which moves from right to left, controlled by the steering wheel 3 and the cable 51, the attachment point of the trailer. is then moved laterally, allowing the shuttle to move from right to left.

 When the user acts on the joystick 3, the lever arm 43 provided with a height-adjustable fastener, acts through the cable 41 on the position of the roller 2.This roller will move the point of action of the trailer cable from bottom to top and front to back which will tip the shuttle to communicate a down or up movement.

 Depending on the depth of immersion, the towing angle is modified. The pneumatic cylinder 42 will be subjected to the pressure of the ambient medium and will thus correct the position of the roller by acting on the cable 41. The user can modify this action by injecting compressed air in this cylinder.

 The towing cable can be connected to the shuttle by a pulley through which a cable 44 slides. This cable has an extract linked to a cleat 45, which can be released by the user to drop the towing cable if necessary. The other part of the cable 44 is connected to a winch 46. This winch is braked by two ribbons 47 which are controlled by a stirrup provided with a roller 48 on which the chable 44 is wound.

 When the trailer experiences an overvoltage the cable 44 acts on the caliper 48 which crushes the spring itself, releasing the tension on the brake tapes 47, the cable 44 is thus released which allows the user to react in the event of an encounter with a obstacle.

 This braking action can be adjusted by the user using the eccentric lever 49, which acts on the brake tension spring and thus blocks or unlocks the winch.

 The industrial applications of this invention are numerous and without limitation in the field of scuba diving and civil protection.

 Sports and professional divers will have with this invention a machine allowing them to move with diving equipment to take it to work, or to lift loads from the seabed and quickly reach the surface, and secure a remote base.

 Underwater research and observations can be undertaken with less logistical means.

This invention can be used for the surveillance of divers or swimmers on the beaches. The propeller protection tunnels allow all changes in safety in an environment where swimmers evolve, and its ability to immerse itself allows immediate rescue of drowned persons below the surface, and quickly reaching a rescue point
This invention will be of great use for a new form of underwater tourism, for example baptisms or underwater excursions.

 The shuttle will also be very useful for aquaculture and similar activities.

 This invention can also be used as an attacking machine for combat swimmers thanks to its speed of movement on the surface and when diving on a snorkel.

 Navy demining divers will be able to use the shuttle for surface and diving surveillance of ports, beaches, and ship hulls.
