Abstract

A device for supporting a propulsor on a marine vessel. The device includes a base that is fixable to the marine vessel and a pivot arm for coupling the propulsor to the base. An actuator is configured to pivot the pivot arm relative to the base into and between a retracted position and a deployed position. A fastener is engageable to couple the actuator to the pivot arm, where when the fastener is engaged the pivot arm is prevented from pivoting other than by the actuator, and where applying a predetermined force on the pivot arm disengages the fastener to allow the pivot arm to pivot other than by the actuator.

First claim

What is claimed is:

1. A device for supporting a propulsor on a marine vessel, the device comprising:
a base configured to be coupled to the marine vessel;
a pivot arm that couples the propulsor to the base; and
an actuator selectively coupled to the pivot arm, wherein when the actuator and the pivot arm are coupled the actuator moves the pivot arm relative to the base into and between a stowed position and a deployed position, and wherein applying a predetermined force on the pivot arm decouples the actuator and the pivot arm to allow the pivot arm to be moved into the stowed position without moving the actuator.

2. The device according to claim 1 , wherein the pivot arm has an opening in an edge thereof, further comprising a pin moveable with the actuator, wherein the actuator and the pivot arm are coupled when the pin is moved towards the edge of the pivot arm and into the opening therein.

3. The device according to claim 2 , wherein the pin is retained in the opening in a press-fit arrangement.

4. A device for supporting a propulsor on a marine vessel, the device comprising:
a base configured to be coupled to the marine vessel;
a pivot arm that couples the propulsor to the base; and
an actuator that moves the pivot arm relative to the base into and between a stowed position and a deployed position;
wherein the pivot arm is a fork having a neck and opposing fork segments, and wherein the actuator is positioned between the opposing fork segments.

5. The device according to claim 4 , wherein the actuator is selectively coupleable to the opposing fork segments such that moving the actuator moves the pivot arm.

6. The device according to claim 1 , wherein the actuator is extendable within a plane, and wherein the propulsor is configured to generate propulsion perpendicular to the plane.

7. The device according to claim 6 , wherein a shaft couples the propulsor to the pivot arm, and wherein the shaft moves within the plane while moving the pivot arm between the stowed position and the deployed position.

8. The device according to claim 1 , wherein the pivot arm is a first pivot arm, further comprising a secondary arm that couples the propulsor to the base, wherein the first pivot arm and the secondary arm remain substantially parallel while moving the pivot arm between the stowed position and the deployed position.

9. A device for supporting a propulsor on a marine vessel, the device comprising:
a base configured to be coupled to the marine vessel;
a pivot arm that couples the propulsor to the base;
an actuator that moves the pivot arm relative to the base into and between a stowed position and a deployed position; and
a lock engageable to prevent the pivot arm from moving relative to the base, wherein the lock is engaged by moving the pivot arm from the deployed position into a locked position that is beyond the stowed position.

10. The device according to claim 9 , wherein the lock is a detent.

11. The device according to claim 10 , further comprising a secondary arm that pivotally couples the propulsor to the base, wherein a lock opening is defined in at least one of the pivot arm, the secondary arm, and the base, and wherein the lock comprises a pin receivable in the lock opening to prevent the pivot arm from pivoting relative to the base.

12. The device according to claim 11 , wherein the pin is biased to be automatically received into the lock opening when the pivot arm is rotated into the locked position.

13. A device for supporting a propulsor on a marine vessel, the device comprising:
a base that is fixable to the marine vessel, the base defining an axle opening therein;
an axle configured to be received in the axle opening of the base;
two forks each extending between a neck and opposing fork segments, wherein one of the two forks is an actuation fork, and wherein the opposing fork segments of the actuation fork are pivotally coupled to the base via the axle, wherein the opposing fork segments of the actuator fork each have upper and lower edges, and wherein an opening is defined through each of the opposing fork segments that is open at the lower edges corresponding thereto;
a shaft with a propulsor configured thereto, wherein the shaft is movable into and between a locked and a deployed position with a stowed position therebetween, and wherein the propulsor is configured to propel the marine vessel in water when the shaft is in the deployed position;
an actuator pivotally coupled to the base, wherein the actuator is a linear actuator, and wherein the engagement arm is sandwiched between the opposing fork segments and the actuator;
opposing engagement arms pivotally coupled to the base via the axle, the opposing engagement arms also being pivotally coupled to the actuator; and
a fastener engageable to couple the actuator to the actuation fork, wherein when the fastener is engaged the actuator prevents the shaft from being moved manually, and wherein applying a predetermined force on the shaft disengages the fastener to allow the shaft to be moved manually.

14. The device according to claim 9 , wherein the actuator is selectively coupled to the pivot arm, wherein when the actuator and the pivot arm are coupled the actuator moves the pivot arm relative to the base into and between a stowed position and a deployed position, and wherein applying a predetermined force on the pivot arm decouples the actuator and the pivot arm to allow the pivot arm to move without moving the actuator.

15. The device according to claim 14 , wherein the pivot arm and the actuator are decoupled when the pivot arm is in the locked position.
