Abstract
A vehicle propulsion system having a mount; a rotation shaft oriented substantially normal to a plane of travel of a vehicle; a fixture coupled to the rotation shaft, the fixture being rotatable about a rotation shaft axis of the rotation shaft; and an oar assembly coupled to the fixture; wherein the coupling is coupled to the fixture, wherein the rotation shaft axis is substantially normal to the rotational axis; wherein the coupling is coupled to the fixture to permit rotation of the oar assembly about the rotation axis when the lock is locked.
Claims14
A vehicle propulsion system comprising:
- a mount for mechanically coupling to a vehicle;
- a rotation shaft oriented substantially normal to a plane of travel of the vehicle;
- a fixture coupled to the rotation shaft, the fixture being rotatable about a rotation shaft axis of the rotation shaft;
- and
- an oar assembly coupled to the fixture, the oar assembly including;
- a first blade;
- a first shaft, the first blade being coupled to a distal end of the first shaft;
- a second blade;
- a second shaft, the second blade being coupled to a distal end of the second shaft;
- a coupling interposed between a proximal end of the first shaft and a proximal end of the second shaft and selectively permitting rotation of the first shaft relative to the second shaft about a rotational axis. Wherein the coupling includes a lock for locking the first shaft relative to the second shaft so as to prevent rotation of the first shaft relative to the second shaft when the lock is locked;
- a first adjuster, wherein the first adjuster adjusts a length of the first shaft;
- and
- a second adjuster, wherein the second adjuster adjusts a length of the second shaft;
- wherein the coupling is coupled to the fixture, wherein the rotation shaft axis is substantially normal to the rotational axis;
- wherein the coupling is coupled to the fixture to permit rotation of the oar assembly about the rotation shaft axis when the lock is locked.
