Boat transporting arrangement

Abstract

The invention includes a boat transporting arrangement ( 11 ) that utilises a frame construction with wheels related thereto and side-related pillar-like supports and one or more carrier straps or like devices disposed between said supports ( 11 a ) and adapted to hold a boat hull (B 1 ). The frame construction is comprised of a number of individual units ( 11, 22 ) which are coupled together ( 31 ). Coupling of a first unit to a second unit affords flexural movement with a horizontal flexure line ( 31 a ′).

         2 . An arrangement according to  claim 1 , characterized in that the arrangement includes at least one spacer arm, and preferably two spacer arms which are spaced horizontally apart.  
     
     
         3 . An arrangement according to  claim 2 , characterized in that the length of the spacer arm corresponds to 30-80% of the length of a unit.  
     
     
         4 . An arrangement according to  claim 1 , characterized in that two parallel-orientated units are coupled together through the medium of one or two transverse beams.  
     
     
         5 . An arrangement according to  claim 4 , characterized in that one beam is adapted to connect together the front parts or centre parts of two mutually adjacent units.  
     
     
         6 . An arrangement according to  claim 5 , characterized in that the other beam is adapted to connect together other parts of two mutually adjacent units.  
     
     
         7 . An arrangement according to  claim 1 , characterized in that each unit includes at least two pillar-like supports whose rotational axes are placed centrally in relation to the unit.  
     
     
         8 . An arrangement according to  claim 7 , characterized in that each unit includes four pillar-like supports with two rotational axes placed centrally relative to the unit and two rotational axes placed distal to the unit.  
     
     
         9 . An arrangement according to  claim 1 , characterized in that respective pillar-like supports are positioned immediately above a wheel axle.  
     
     
         10 . An arrangement according to  claim 1 , characterized in that the unit is comprised of a frame construction to which at least two boggy-suspended and pivotal wheel pairs are attached.  
     
     
         11 . An arrangement according to  claim 1  or  claim 10 , characterized in that at least four boggy-suspended wheel pairs are attached two-and-two to the frame construction.  
     
     
         12 . An arrangement according to  claim 1  or  claim 11 , characterized in that double boggy-suspended wheel pairs, at least four such wheel pairs are attached two-and-two to the frame construction.  
     
     
         13 . An arrangement according to  claim 12 , characterized in that an even number of frame constructions, such as four frame constructions, are coupled together to form a U-configuration.  
     
     
         14 . An arrangement according to  claim 1 , characterized in that the pillar-like supports of a unit are comprised of hydraulic piston-cylinder devices that are coupled together hydraulically.  
     
     
         15 . An arrangement according to  claim 1  or  claim 4 , characterized in that the distance between two mutually coupled units can be adjusted through the medium of said one or more transverse beams.  
     
     
         16 . An arrangement according to  claim 1 ,  4  or  16 , characterized in that the transverse beams are positioned at the same height from an underlying supportive surface as the wheel axles.  
     
     
         17 . An arrangement according to  claim 1 , characterized in that a unit, on each side of the boat, includes an own motor-driven hydraulic pump with control unit; and in that each further unit on the same side is coupled hydraulically to the unit provided with said hydraulic pump.  
     
     
         18 . An arrangement according to  claim 1 , characterized in that each unit includes means for activating rotation of the wheels.  
     
     
         19 . An arrangement according to  claim 14  or  claim 17 , characterized in that pillar-like supports belonging to parallel-related units are coupled together hydraulically.  
     
     
         20 . An arrangement according to  claim 14  or  claim 17 , characterized in that pillar-like supports belonging to series-related units are coupled together hydraulically.
