Watercraft

Abstract

The invention relates to a watercraft comprising a hull, at least one motor which is fixed in or onto said hull, and a propeller which is driven by the motor by means of a transmission. According to the invention, at least part of the underwater transmission and the propeller can be laterally pivoted in relation to the watercraft by means of rotary elements.

1 . Watercraft, comprising a hull, at least one motor attached in or on the hull, and a propeller driven by a motor through a transmission, 
 characterized in that at least one component of the underwater transmission and the propeller are laterally pivotable by pivoting means relative to the watercraft.    
   
   
       2 . Watercraft according to  claim 1 , characterized in that the propeller is manually or automatically pivotable into positions selected at will.  
   
   
       3 . Watercraft according to  claim 1 , characterized in that the propeller is pivotable into positions selected at will, and that the propulsive function of the propeller is ensured in at least two laterally pivotable positions.  
   
   
       4 . Watercraft according to  claim 1 , characterized in that the propeller is able to operate in a fully-immersed state, partially immersed state, or as a jet drive.  
   
   
       5 . Watercraft according to  claim 1 , characterized in that a water intake for the propeller is located in the hull in a state which is pivoted relative to that of normal operation.  
   
   
       6 . Watercraft according to  claim 5 , characterized in that the water intake is an open and/or closed channel.  
   
   
       7 . Watercraft according to  claim 5 , characterized in that a water intake opening of the water intake is located laterally on the side and/or in the bottom region of the watercraft.  
   
   
       8 . Watercraft according to  claim 5 , characterized in that the water intake, and thus the water intake opening, is closable by a flap valve, and that the water flow supplied to the propeller is controllable by the flap valve.  
   
   
       9 . Watercraft according to  claim 8 , characterized in that the pivoted propeller interacting with the water intake and the flap valve forms a lateral/transverse thruster.  
   
   
       10 . Watercraft according to  claim 1 , characterized in that the pivoting means are composed of a pivoting component in the case of motors with a horizontally oriented crankshaft, and of a pivoting component and a right-angle drive that is flange-mounted between pivoting component and motor in the case of motors with a vertically oriented crankshaft.  
   
   
       11 . Watercraft according to  claim 10 , characterized in that the pivoting component comprises: a bearing and pivot seating component connected, possibly through additional elements, to the motor; a swivel component rotatable about the bearing and pivot seating components, the propeller being effectively linked to the swivel component; and means to rotate the swivel component.  
   
   
       12 . Watercraft according to  claim 1 , characterized in that the lateral swivel motion of the propeller is effected by steering movement on the steering wheel of the watercraft.  
   
   
       13 . Watercraft according to  claim 1 , characterized in that the lateral swivel motion of the propeller is triggered by the measurement signal from a depth gauge.  
   
   
       14 . Watercraft according to  claim 1 , characterized in that in response to a lateral swivel motion by the propeller the speed of the motor is adjustable to the prevailing situation.  
   
   
       15 . Watercraft according to  claim 1 , characterized in that a swivel motion by a pivotable fin is effectively linked to the lateral swivel motion of the propeller so as to protect the propeller.  
   
   
       16 . Watercraft according to  claim 1 , characterized in that the underwater transmission, and thus the propeller, are also longitudinally pivotable.  
   
   
       17 . Watercraft according to  claim 1 , characterized in that hydraulic or electric lines are routed within the underwater transmission.  
   
   
       18 . Watercraft according to  claim 17 , characterized in that a hydraulic motor or electric motor provides the propulsion for the propeller.  
   
   
       19 . Watercraft according to  claim 1 , characterized in that the motor, in particular in the case of outboard motors, is laterally pivotable together with the propeller.
