Modular Construction System For Floating Structures Such As Boats

Abstract

An assembly of mouldings that can be joined together and used as boats or other floating structures. The mouldings are advantageously of rotational moulded plastics material and can be of identical shape. Each of the mouldings has an outer face incorporating at least two zones that are advantageously flat and disposed at an angle one to the other so that one moulding can be joined to another face-to-face in different configurations. In one of such configurations, the first zone of one of the mouldings is in face-to-face relationship with one of the zones of another of the mouldings. In another embodiment the second zone of the one moulding is in face-to-face relationship with one of the zones of the other moulding. The mouldings have outer profiles that are substantially similar. The profiles are advantageously hexagonal. Some mouldings may be joined together end-to-end at end faces that are in face-to-face relationship.

1 . An assembly of mouldings that can be joined together and used as a floating structure, the assembly comprising a first moulding and a second moulding each of which is produced by a rotational moulding process and has an outer face incorporating a first zone and a second zone which zones are so shaped that the first moulding can be joined to the second moulding in a first disposition in which the first zone of the first moulding is in face-to-face relationship with one of the zones of the second moulding or in a second disposition in which the second zone of the first moulding is in face-to-face relationship with one of the zones of the second moulding.  
   
   
       2 . An assembly of mouldings according to  claim 1 , in which the mouldings include a third moulding having an outer face incorporating a first zone and a second zone which zones are so shaped that the third moulding can be joined to the second moulding in a first disposition in which the first zone of the third moulding is in face-to-face relationship with one of the zones of the second moulding or in a second disposition in which the second zone of the third moulding is in face-to-face relationship with one of the zones of the second moulding.  
   
   
       3 . An assembly of mouldings according to  claim 1 , in which the first zone and the second zone of each moulding comprise each a flat portion of the outer face of the moulding, the flat portions being disposed at an angle one to the other.  
   
   
       4 . An assembly of mouldings according to  claim 1 , in which the mouldings have outer profiles that are substantially similar one to the other.  
   
   
       5 . An assembly of mouldings according to  claim 4 , in which the mouldings have substantially similar outer profiles that are of hexagonal shape.  
   
   
       6 . An assembly of mouldings according to  claim 1 , in which at least one moulding has an end face that is disposed in face-to-face relationship with an end face of a fourth moulding to which said at least one moulding is joined.  
   
   
       7 . An assembly of mouldings according to  claim 1 , in which the mouldings are of moulded plastics material.  
   
   
       8 . A hull-and-deck structure for a boat comprising an assembly of mouldings according to  claim 1.
