Self-contained diving system with an automatic alarm

Abstract

The invention relates to a diving system for several persons in which, without using any type of motors and being self-contained, the cylinder used is attached to a mobile float which is pulled along by the users by means of air-carrying hoses of an adjustable size, which are floating and flexible and fitted with rotary terminals, the components thereof including an automatic underwater alarm actuated by the compressed air from the actual cylinder and having a quick-release pin which releases the belt from the user without interrupting the flow of air.

1 . A self-contained diving system with an automatic alarm, characterised in that, being self-contained, it incorporates the compressed air cylinder separated from the users and attached to a mobile float ( 1 ) provided with emergency floats ( 14 ), the entire unit being pulled by the divers by means of hoses of adjustable size fitted with rotary terminals, with the air, the discharge pressure of which has increased by  2  bars above the usual pressure, flowing from the reinforced low pressure outlet of the first stage regulator ( 5 ) to the second stage regulators ( 32 ) which are attached to the belts ( 26 ) incorporating a multifunctional part ( 29 ) with a release pin ( 30 ) which clamps the hose, and wherein an automatic underwater alarm ( 6 ) actuated by the compressed air in the cylinder is also connected to the first stage regulator, with replaceable contact plates of different diameters ( 6 F) and a spherical bell pushbutton ( 10 ). 
     
     
         2 . The self-contained diving system with an automatic alarm according to  claim 1 , characterised in that its threaded rotary connection ( 23 ) has a plastic ring ( 23 D) between the threaded lock nut and the connection plate with an O-ring.
