Abstract
Abstract A sailing simulator comprising: a hull provided with a boom and a rudder; first supporting means for supporting the hull through the intermediary of springs for heeling motion; second supporting means for supporting the first supporting means for rotation about a vertical axis; and drive means for causing the first and second supporting means to effect heeling motion and rotation, respectively; and means operable in response to the handling of the boom and/or the rudder to control the drive means. An elastic means is interposed between the first supporting means and the drive means therefor so that the hull can be moved about the heeling axis by positional change of the weight of the trainee on the hull. Means is also provided for application of a reactive force to the boom as the boom and/or the rudder are handled.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
Sailing simulator comprising: a hull provided with a boom for handling a sail and a rudder; first supporting means, first elastic means interposed between said hull and said first supporting means for resiliently mounting said hull to said first supporting means, second supporting means for supporting said first supporting means so that said first supporting means is swingable about the longitudinal axis of said hull, said second supporting means being rotatable about a vertical axis; drive means for causing said first supporting means to swing about said longitudinal axis and said second supporting means to rotate about said vertical axis; and second elastic means interconnecting said first supporting means and said drive means for summing the driving force from the drive means to swing said first supporting means and the force produced by the weight and position of a crew.
Claim 2
Dependent Claim

Sailing simulator comprising: a hull provided with a boom for handling a sail and a rudder; first supporting means, first elastic means interposed between said hull and said first supporting means for resiliently mounting said hull to said first supporting means, second supporting means for supporting said first supporting means so that said first supporting means is swingable about the longitudinal axis of said hull, said second supporting means being rotatable about a vertical axis; drive means for causing said first supporting means to swing about said longitudinal axis and said second supporting means to rotate about said vertical axis; and second elastic means interconnecting said first supporting means and said drive means for summing the driving force from the drive means to swing said first supporting means and the force produced by the weight and position of a crew.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1, wherein said first elastic means comprises coil springs.
Claim 4
Dependent Claim
13 words
The apparatus of claim 1, wherein said first elastic means comprises leaf springs.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1, further including means for periodically moving said hull relative to said first supporting means thereby to give said hull a pitching motion.
Claim 6
Dependent Claim
47 words
The apparatus of claim 1, further including means for biasing said boom so that as said boom is rotated about a mast in a predetermined direction, a reactive force acting on said boom increases, while as said boom is rotated in the opposite direction, said force decreases.
Claim 7
Dependent Claim
25 words
The apparatus of claim 5, further including means operable in response to the handling of said rudder to apply an additional force on said boom.
Claim 8
Dependent Claim
79 words
The apparatus of claim 5, wherein said biasing means comprises a crank arm which is rotatable about said vertical axis and displaced 180° from said boom; means for applying a force to said crank arm to rotate the same about said vertical axis, and means for effecting transmission of rotation between the axes of rotation of said crank arm and said boom in such a manner that said transmission of rotation is unaffected by heeling motion of said hull.
Claim 9
Dependent Claim
39 words
The apparatus of claim 7, wherein said force applying means comprises a spring having one end connected to said crank arm and means connected to the other end of said spring for changing the initial tension of said spring.
Claim 10
Dependent Claim
45 words
The apparatus of claim 7, wherein said force applying means comprises elastic means operatively connected to said crank arm, and means for changing the characteristics of said elastic means in accordance with said longitudinal axis of said hull relative to the direction of the wind.
Claim 11
Dependent Claim
66 words
The apparatus of claim 7, wherein said force applying means comprises a first spring operatively connected to said crank arm; means for changing the characteristics of said first spring; a second spring operatively connected to said crank arm; and means operable in response to the rotation of said second supporting means to change the force of said second spring to be applied to said crank arm.
Claim 12
Dependent Claim
53 words
The apparatus of claim 1 wherein said second elastic means includes a first arm connected to said drive means, a second arm connected to said first support means, and a pair of springs interconnecting corresponding ends of said first and second arms so as to allow said arms to assume a non-parallel relationship.
