Abstract
Abstract A rudder construction for small boats, particularly sailboats, in which the rudder is mounted on its rotatable support frame for pivotal movement on a horizontal axis to prevent damage to the rudder in the event that it strikes an obstruction in the water. A detent means yieldably retains the rudder in its normal vertical position or a horizontal or intermediate position. The tiller may be manipulated to move the rudder to any of said positions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A rudder construction for boats comprising a rudder support member mounted on the transom of the boat for rotation on a vertical axis, a rudder carried by said support for rotation therewith, said rudder being pivoted on a horizontal axis on said support for movement between a normal vertical position and a generally horizontal position, detent means between said support and rudder for releasably holding the latter in either of said positions, said detent means including a movable member connected to said rudder, a tiller for rotating said support on said vertical axis, and an operating means associated with said tiller, said operating means normally being disposed out of engagement with said movable member whereby said rudder is movable from said vertical position to said horizontal position without causing movement of said tiller and being manually operable to engage said movable member to shift said rudder between said positions upon movement of said tiller.
Claim 2
Dependent Claim
154 words
A rudder construction for boats comprising a rudder support member mounted on the transom of the boat for rotation on a vertical axis, a rudder carried by said support for rotation therewith, said rudder being pivoted on a horizontal axis on said support for movement between a normal vertical position and a generally horizontal position, detent means between said support and rudder for releasably holding the latter in either of said positions, said detent means including a movable member connected to said rudder, a tiller for rotating said support on said vertical axis, and an operating means associated with said tiller, said operating means normally being disposed out of engagement with said movable member whereby said rudder is movable from said vertical position to said horizontal position without causing movement of said tiller and being manually operable to engage said movable member to shift said rudder between said positions upon movement of said tiller.
Claim 3
Dependent Claim
43 words
Rudder construction according to claim 1 wherein said movable member is pivotally connected to said rudder and slIdably disposed within said support, and a fixed detent element on said support and cooperable with said movable member to define said positions of said rudder.
Claim 4
Dependent Claim
70 words
Rudder construction according to claim 2 wherein said operating means comprises an axially movable rod mounted on said tiller and spring means urging said rod out of engagement with said movable member, said movable member having an opening therein adapted to receive one end of said rod and said tiller being movable in a vertical plane to align said rod with said opening in any position of said movable member.
Claim 5
Dependent Claim
54 words
Rudder construction according to claim 2 wherein said rudder support member has an upwardly and rearwardly inclined slot therein and said movable member comprises an elongated bar slidably confined within said slot, said bar having a plurality of notches thereon, said fixed detent element being secured within said slot and engageable in said notches.
Claim 6
Dependent Claim
26 words
Rudder construction according to claim 4 wherein one of said notches on said bar defines a position of said rudder intermediate said vertical and horizontal positions.
