Self-contained ecological dynamic boat pitch and roll trim system by alteration of the hull water flow

Abstract

The self contained ecological dynamic boat pitch and roll trim system by alteration of the hull water flow, of this invention consists of a main body ( 1 ) inside of which an elastic flexible pressure means ( 5 ), is being housed properly, located on supporting plates ( 4 ), compression-retraction springs ( 7 ) of said flexible elastic pressure means ( 5 ), spring guides ( 8 ), spring housing tubes ( 9 ), a hydrodynamic barrier ( 6 ), a back guide ( 2 ) and a front guide ( 10 ) for the hydrodynamic barrier ( 6 ) and a cover ( 3 ), being characterized in that said flexible elastic pressure means ( 5 ) is being independent and self contained, said system is also being capable of operating with no seals by use of only water, requiring no dedicated water pump, is being capable of being self cleaned internally and has the form of a cubic shape.

1 . A self contained ecological dynamic boat pitch and roll trim system by alteration of the hull water flow, consisting of a main body inside of which an elastic flexible pressure means, is being housed properly, located on supporting plates, compression-retraction springs of said flexible elastic pressure means, spring guides, spring housing tubes, a hydrodynamic barrier, a back guide and a front guide for the hydrodynamic barrier and a cover, being wherein said flexible elastic pressure means is being independent and self contained, said system is also being capable of operating with no seals by use of only water, requiring no dedicated water pump, is being capable of being self cleaned internally and has the form of a cubic shape. 
     
     
         2 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1 , wherein said independent flexible elastic pressure means, is being capable of exerting pressure and force throughout its surface, due to its nature, by requirement of a very small operating pressure of 1-3 bar and the use of a non compressible fluid, which fluid due to the system designing and application is being the water, requiring no additional independent hydraulic pump unit, for it is able of using the existing boat water installation unit, according to said boat water installation unit operating parameters. 
     
     
         3 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1 , wherein it is capable of being used with no seals, this providing the internal free water circulation via its main body, further resulting to a hydrodynamic self cleaning effect from fouling of any kind. 
     
     
         4 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1  wherein in the event of failure of said independent flexible elastic pressure means, either due to wear or due to an accident, not even the least of environmental pollution is likely to be caused, since water is only used. 
     
     
         5 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1  wherein is being capable of being either partially or fully repaired while the boat is being in the water. 
     
     
         6 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1 , wherein the compression springs are capable of being replaced by any other elastic means being suitable, while the command for the water feed to said independent flexible elastic pressure means can be given by any mechanical way known. 
     
     
         7 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in  claim 1 , wherein, in retracted mode a minimal or no water volume is contained inside said elastic means that is being retained in this position by the compression force exerted by the springs, while at the same time the hydrodynamic barrier is being at the top position without the hull water flow being affected such that, by giving a suitable command, a volume of water is inserted inside the elastic means said begins expanding thus pushing and moving the hydrodynamic barrier simultaneously to the operation position, white the reverse action is achieved by relieving of fluid, assisted by the compression springs via the same supply pipe and by the use of a suitable three way flow connector. 
     
     
         8 . The dynamic boat pitch and roll trim system by alteration of the hull water flow as in claim  1 , wherein it constitutes a unit capable of being produced in any desirable length since its design makes it possible for that dimension. 
     
     
         9 . The dynamic boat pitch and roll trim system by alteration of the hull water flow like in  claim 1 , wherein due to being in the form of a compact unit is capable of being fixed in small boats which until now could not bear a classic trim system because of the passenger movement through these spaces, so that no injuries are caused whatsoever.
