| 440101000 | OAR OR PADDLE | 31 |
| 20080242163 | Articulated oar system - An oar system is provided that keeps the blade of the oar at approximately 90 degrees to the centerline or keel of a boat throughout the normal power producing stroke. This reduces the lost effort that is expended when operating oars whose blades are fixed to the oar shaft. A series of cables and pivotal attachment points holds the oar blade at the approximate 90-degree angle to the boat keel. | 10-02-2008 |
| 20080254691 | Kayak paddle - A kayak paddle for increasing paddle stroke efficiency and for improving comfort in paddle handling has a pronounced bent blade to length design of the paddle blade, as compared with prior paddle blades. The paddle has two blades, one blade secured at its top end to each end of a paddle shaft with a longitudinal axis. The bottom end of each blade extends forward of and above the longitudinal axis of the shaft, such that the chord line between the bottom end and top end of the blade intersects the longitudinal axis. The blade's length to radius of its arc is greater than 12 to 1. Through slots can be provided in the blades for stabilization and to minimize flutter. In addition, the paddle shaft is ergonomically shaped to fit the user's hand. | 10-16-2008 |
| 20090004935 | Winged oar or paddle - My invention is a handy oar or paddle, which is used by hand. The invention is used to help the boat move forward on the water while we are sitting in the boat. The invention's goal is to move forward faster with the boat using the oars or paddles, while not using extra force rowing the boat, and not changing anything on the boat. I can achieve this with the oar or paddle by not only rowing with the oar or paddle, but by pushing myself forwards. On the bottom of the blade, there is a slanted wing put up. On the bottom of the blade, above the wing, there is an opening. This is my invention. When we are moving forward with the boat, the wing on the bottom of the blade is higher on the side of the blade, which is facing the back of the boat. The wing is put up on the bottom of the blade slanted. This makes it possible when rowing the oar or paddle that the water control wing controls, pushes the oar or paddle in the water. This gives an upward force to the blade. For this we push the oar or paddle downwards, and use it to move forwards, while we lean on the oar. We row with the invention and we push ourselves forwards, this way we use the same amount of force, but moving forwards faster with the boat. | 01-01-2009 |
| 20090036007 | Sculling oar handle cover - The sculling oar handle cover is used to reduce friction between a sculling rower's fingers/hands and the existing sculling oar handle during rowing, thereby reducing the risk of blisters and other damage to the skin. The cover is affixed to the existing oar handle by sliding it over the handle and securing it with a Velcro fastener. Due to the required stoking method for sculling, the sculling oar handle cover virtually eliminates the friction caused by the continuous rotating of fingers/hands on sculling oar handles. Additionally, because the sculling oar handle cover must be wetted to function property, the slipping of fingers/hands on the oar handles is unlikely even with the release of body oils or the splashing of water on the oar handle covers. | 02-05-2009 |
| 20090280702 | System of easily interchangeable handles for oars - The present invention is a system of easily interchangeable handles for oars used in the sport of crew. | 11-12-2009 |

A further improvement includes using the handgrip in the position perpendicular to the paddle shaft to determine the blade position by feel and steer with greater torque. An alternative embodiment includes rotation of the grip itself, further reducing the twisting of the wrists and other joints. | 05-20-2010 |
| 20100167606 | FORCE SENSING OAR - A system for determining the magnitude of force applied to an oar by a rower as the oar is pulled through water includes a deflection sensor and a temperature sensor mounted on an oar shaft to determine deflection and temperature of a portion of the oar shaft during rowing. A processor connected to the deflection sensor and the temperature sensor receives signals indicative of deflection and temperature of the oar shaft and derives a force applied to an oar blade based on the deflection and temperature signals. | 07-01-2010 |
| 20100279560 | PADDLE BLADE AND SHAFT I-BEAM JOINT - A paddle including a shaft having a distal end, the distal end ending in a protrusion; and a paddle blade having a proximal end joined to the distal end of the shaft, the proximal end having an inner surface and at least one internal longitudinal slot disposed adjacent to the inner surface engaged with the protrusion. | 11-04-2010 |
| 20110065341 | Push Paddle - A push-paddle has a buoyant wedge-shaped push-block attached to the bottom end of a pole. When pressed into the water wedge-end first, the push-block provides high drag and buoyant force for the user to push against and propel a watercraft using a punting-like motion. At the end of the power stroke, the wedge slips easily and quickly up out of the water allowing the user to recoil the push-paddle through the air. | 03-17-2011 |

A joint connecting the shaft halves may include an interlocking coupling and a biasing member. The interlocking coupling maintains, in a use configuration, the offset angle of the blades, and allows, in a selection configuration, a change in the offset angle of the blades. The biasing member typically holds the interlocking coupling in the use configuration, and the shaft halves may be moved axially apart for the selection configuration. All mechanisms for switching the interlocking coupling between the use configuration and the selection configuration are normally located within the shaft halves. A retaining clip may be coupled between the first and second shaft halves to allow the selection configuration while preventing disassembly of the first and second shaft halves.

This axis is attached to an arm loom fixed to a housing immersed in the water, at the other end. This housing supports shafts with oar blades hinged on them, and gates connected to them in parallel position. These shafts are attached with levers joined by a plate. A spring keeps the gates in the closed position, and stops the oar blades when they are pushed up by water's resistance. A cable connects these levers on the housing to one lever located on the handlebar; when this lever is pulled by the rower, the cable drags the housing's levers and opens the gates. The whole mechanism is supported by a block attached to the axis, and fixed at the boat by clamps. | 04-02-2009 |
