20110027101 | CONVERTIBLE PADDLE SYSTEM - A paddle useful for paddle boarding comprises a shaft having a first end and an opposed second end, a first blade at the first end of the shaft, and a handle at the second end of the shaft. There is a second blade proximate the second end of the shaft. The second blade is moveable between first and second positions. The first position allows the handle to be used by the second blade being closer to the first end of the shaft that is the handle, i.e., a single blade configuration. In a double blade configuration, the second blade is in a second position that allows the second blade to be used by a portion of the second blade extending at least as far as the handle. | 02-03-2011 |
20130039776 | Whitewater Hand Paddles - A hand paddle having a handle (hand grip) attached to the hand paddle blade allows the user to grip the hand paddle intuitively and ergonomically for use in whitewater with kayaks or boats. The paddle blade has a contoured hand well, which allows the handle to be positioned closer to the hand paddle blade substantially reducing the rotating force (torque) to the user's hands. The handle configuration allows user to quickly release the paddle in order to use hands in case of an emergency. The hand paddle further comprises a hand strap to prevent the paddle from rotating/pivoting in the user's hands. The hand paddle further comprises a lanyard, designed to break away under the weight of the user, securing the hand paddle to the user's wrist or forearm. | 02-14-2013 |
20140037457 | ADJUSTABLE PADDLE - A joint is provided for a double bladed paddle which allows for the angle between the blades to be adjusted relative to one another. The joint is formed from joining a female body recessed into a first shaft with a male body extending from a second shaft. The female body encloses a spring mechanism abutted by teeth of a crown with receiving grooves. The male body has protuberances which fit within the receiving grooves leading to the spring mechanism which when pushed in by the male body allows the protuberances to move past the receiving grooves and rotate to slot into the pockets formed between the teeth of the crown. | 02-06-2014 |
20140133997 | PADDLE - A paddle is disclose(the paddle comprises a blade, an intensified structure and a handle. The blade comprises a body and a tubular section extending from the body. The body is provided with a reception hollow communicated with the interior of the tubular section. The intensified structure comprises a joint section and an intensified section. The one end of the joint section engages fixedly in the inside of the tubular section of the blade. The handle is joined to the other end of the joint section. The paddle of this invention exploits the intensified structure to heighten the structural strength of the blade, which substantially decreases the possibility of breakage of the blade due to the propelling force. | 05-15-2014 |
20140271224 | PADDLE - A paddle device. First and second paddle assemblies each have a paddle blade extending from a paddle end of a paddle arm so that the paddle structures each have a paddle blade end and a paddle arm end. A hand crankable crank shaft arrangement have a center and first and second ends and having handle segments. The paddle arm end of the first paddle structure is coupled to the first end of the crank shaft arrangement and the paddle arm end of the second paddle structure is coupled to the second end of the crank shaft arrangement. First and second handle grips are rotatably coupled to the crank shaft arrangement so as to permit the crank shaft arrangement to rotate with respect to the first and second handle grips when the crankshaft arrangement is cranked. This abstract is not to be considered limiting. | 09-18-2014 |
20160052611 | PADDLE-INTEGRATED COMMUNICATION DEVICE - A paddle apparatus for use by a user, of a vessel, to propel the vessel through water may include a shaft having a first end and a second end that is opposite of the first end; a first blade that is attached to the first end; a handle or a second blade that is attached to the second end; and an electronic communication device that is integrated within or attached to the handle, the shaft, or the second blade. The electronic communication device may enable the user to communicate with another user or authorities via a network or over the air. | 02-25-2016 |

20080232964 | Daisy fan - Here is disclosed an elongate style portable mechanical fan device having an elongate body handle portion including a four blade fan device mounted on the top end of the body portion. The elongate handle portion is designed with a spring loaded grip for mechanical squeeze operation. A twist top scent canister is mounted on center at the top of the four blade fan device. A further embodiment contemplates that scent drops may be added to a mini sponge located in this scent canister or a scent stick may be added in place of the mini sponge, so that the rotating fan blades will disseminate the scent emanating from the scent canister. | 09-25-2008 |
20100003135 | BLANK CONFIGURABLE AS A MANUALLY OPERABLE FAN OR DISPLAY - Disclosed is a blank (200) formed of resiliently flexible sheet material. The blank comprises a first portion (208) operative in a planar configuration and a second portion (204) having means (210, 218) for joining thereof upon configuring of the second portion to form a tubular structure (240). Also disclosed are a manually operable fan configurable from the blank, and a display article configurable form the blank. | 01-07-2010 |
20130101418 | ADJUSTABLE PADDLE - Embodiments are disclosed that relate to adjustable kayak paddles. One disclosed embodiment provides a paddle including a first shaft section having an outer surface with one or more indicia and a second shaft section angularly positionable relative to the first shaft section about a paddle axis, the second shaft section being configured to at least partially surround the outer surface of the first shaft section is provided. The second shaft section further includes a viewing opening configured to permit viewing of one or more of the indicia therethrough when the first and second shaft sections are coupled together. The paddle further includes a coupler operable to releasably couple the first shaft section with the second shaft section at a plurality of angular positions. | 04-25-2013 |

20140017084 | HYDRO-IMPELLED KAYAK PADDLE - A kayak paddle has blades configured to generate forward kayak momentum in each one of the three paddling movements, being more effective than known paddles, using its hydrodynamic profile to reduce formation of turbulent and eddy currents when moved in the water both, during insertion and retrieval. The paddle is characterized by a blade with a cross section in which both edges are curved, the frontal face is convex, and the back face is either flat, concave or both, but not convex, so as to benefit from the water flow around the surface or “Bernoulli Effect”, specifically on insertion in deep water and retrieval from it, producing forward motion of the kayak due to such hydrodynamic forces. | 01-16-2014 |
