FR2577511A1 - Nautical device for lift, advance on the surface and underwater travelling - Google Patents

Abstract

The device is constituted by a chassis which supports a mounting, the superstructure of which positions an impermeable translucent helmet 7 which forms a stabilising float and is connected to an air intake 9 combined with an infrastructure formed by two ballasted floats 20 which make possible an immersion which is adjustable in depth by variation of the volume of air. It is intended to make possible displacement of a user on the surface and to carry out on command underwater diving to the desired depth.

Description

 Nautical device for lift, advancement on the surface and underwater walk.

 It is intended to allow the movement of a user on the surface and to ensure the order of scuba diving to the desired depth.

 It is known to produce surface and diving machines but having a complex structure and a diving mechanism requiring a large driving force.

 The device according to the invention eliminates these drawbacks and gives the possibility of producing an individual diving element with muscular propulsion and without any mechanical organ or requiring power consumption while allowing movement on the surface and the panoramic underwater walk.

 It consists of a chassis carrying a mount, the superstructure of which positions a waterproof translucent helmet forming a stabilizing float connected to an air supply combined with an infrastructure formed by two ballasted ballast floats allowing an immersion adjustable in depth by variation in volume. of air.

In the accompanying drawings, given as a non-limiting example of one of the embodiments of the subject of the invention
Figure 1 is an elevational front view of the device as a whole.

 Figure 2 is an elevational and side view of the floating and diving apparatus.

 The device consists of a frame 1 formed by side members and cross members supporting two floats 2, 3.

 This chassis comprises a propellant carrier pivot for surface 4 and for diving advance 5.

 The upper part of the chassis is provided with a seat 6, a helmet holder mount or transparent bell 7 housing the head of the user.

 The front wall is provided with an adjustable level 8.

 The conduits 9, 10 connect the compressed air tank 11 maintained on the surface by float 12 to the points of use.

 The duct 9 is controlled by a valve 13 making it possible to adjust the air pressure inside the helmet 7.

 The duct 10 via the valve 14 realizes air pressure in the ballast floats 23.

 Each ballas float is provided with orifices these 15, i6 allowing water to penetrate.

 The valve 17 allows the air to enter and expel the water through the openings 15, 16. The valve 18 allows the air to escape and the water to enter the float through the openings 15, 16 , the depth of the immerslon is varied. Releasable ballast 20, 21 count this set.

 The comfortably seated user propels the machine through the oars 22, 23 when it is on the surface.

 While diving, he fixes his oars or fins on the supports 5 and uses the surface 24 like a palm in order to ensure advancement.

 The face 24 of the plunger is always sheltered from the surrounding water because the air stored in the bell 7 prevents the internal level from rising.

 He can breathe freely and have a panoramic view of the underwater environment.

 To immerse yourself, simply open the valves 15, 16 and let the air escape through the orifice 18.

 The floats fill up, driving the craft to the bottom.

 The ballast 20, 21 and the bell 7 ensure the stabilization of the assembly.

 For the ascent, it suffices to open the valve 17 so that the air in the reservoir drives out the water from the floats. We can also drop the weights 20, 21.

 This extremely simple and easy-to-handle vehicle allows anyone to carry out seabed prospecting without any risk and at low cost.

 However, the shapes, sizes and arrangements of the various elements may vary within the limit of equivalents, as indeed the materials used for their manufacture without changing for this, the general conception of the invention which has just been described.
