Abstract
A submersible device for lifting a boat over water has a couple of pneumatic containers (1, 2) and an air compressor (27) for their inflation and deflation through valves (25) arranged in the pneumatic containers (1, 2). The pneumatic containers (1, 2) of the couple are interconnected by means of flexible cross members (3) supporting the boat when the pneumatic containers (1, 2) are inflated.
Description
- The present invention relates to a submersible device for lifting a boat over water. In particular, the invention relates to a device having components capable of modifying their trim in the water to allow a boat to be lifted out of water when the boat is not used; these components sink to free the boat when it is to be used.
- It is known that the use of boats especially at sea causes the growth of vegetation and animals on the submerged parts of the hull. This build-up, which adversely affects boat performance, is difficult to remove. Boat owners try various expedients to remove their boat from the water when it is not used, but this operation is laborious and requires expensive equipment, specialized personnel and space for landing the boat on the beach or mooring at a dock. For this reason, many patents teach how to solve this problem. Some previous documents are mentioned below.

Figure 10 . Thepneumatic containers 1, 2 (only thepneumatic container 2 is visible inFigures 10 to 13 ) must be sunk by sucking the air therein through theair compressor 27 and theair passage tube 28 which branches off to thevalves 25 of eachpneumatic container Figure 11 shows thepneumatic container 2 while being deflated but still on the water surface P.Figure 12 shows thepneumatic container 2 at half depth, while inFigure 13 , it is completely deflated, on the bottom S. Now, the boat I is free to put out into the deep, after having disconnected thepipe 28 from theair compressor 27. - It should be understood that the sinking can be accelerated by an adequate ballast not shown in the figures. Furthermore, it is evident that the
air compressor 27 could be provided on the quay instead of on the boat I. The device according to the present invention has the advantage of being substantially universal, because it is adaptable to each boat. In fact, as shown inFigure 9 , the length of the cross members can be adjusted by superimposing at least twometal strips 13 joined together by bolts in theircoaxial holes 29.
