Definitions

• the present invention relates to the field of paddles.
• the invention more particularly relates to a paddle having a first rod having mutually opposite first and second ends, a first blade integral with the first rod and located in extension of its first end on a longitudinal axis of the first rod, and a mouthpiece. fixed on the second end of the first rod and having a bearing olive.
• support olive means a transverse handle for exerting, with the palm of one hand, a thrust in the longitudinal axis of the rod, while it is held with the other hand .
• Such paddles called simple paddles, are used for the propulsion of boats such as canoes, canoes, canoes or rafts.
• single paddles are less suitable for the propulsion of other types of boats, such as kayaks, in which paddles known as double paddles are normally used, since they comprise two blades, each blade being located on one of the two ends of the stem.
• Double paddles have the ergonomic advantage of allowing two pulses into the water in a single cycle of the paddler's arm movement, but are not, however, easily usable in a boat of too great width.
• This disclosure is to provide a paddle to overcome these disadvantages. This goal is achieved by the fact that this paddle also has a female connector substantially aligned with the longitudinal axis and accessible through the tip.
• the female connector can lead to an external surface of the olive.
• the possible accessory can be attached to the female connector through the olive, particularly simple manner.
• the tip can be attached to an outer surface of the first rod, which allows for easier assembly of the tip and the rod, while providing a larger section female connector.
• the tip can be divided longitudinally into two parts, which allows to fix it on the outer surface of the first rod by connecting the two parts transversely by voltage constrained connectors.
• the olive can be movable between a first position, located in front of the connector, and a second position, in which the olive remains secured to the first rod, but discovers the connector.
• this mobile olive does not constitute an obstacle to the attachment of an accessory to the female connector, even if it is not separated from the paddle.
• the olive can be movable by pivoting between said first and second positions, in particular with a pivot axis substantially orthogonal to the longitudinal axis of the first rod, the axis of pivoting of the olive being able to be more particularly substantially orthogonal to a main axis of the olive.
• the disclosure also relates to the aforementioned paddle together with an accessory adapted to be secured in the connector of the second end of the first rod.
• This accessory may include a second blade, to form a double paddle.
• the accessory may also include a second rod, shorter than the first rod, to obtain an ergonomically appropriate distance between the two blades, this distance being typically greater than the ergonomically appropriate distance between the blade and the blade. olive in a single paddle, but less than twice at that same ergonomically appropriate distance between pale and olive.
• an inner wall of said female connector may have a housing adapted to receive a retractable member laterally projecting from a complementary male connector, for axial locking of the connectors.
• said inner wall may have an oblong recess, oriented towards the housing, to from an outer edge of the inner wall.
• this oblong recess may in particular have a decreasing depth towards the housing and / or be substantially parallel to the longitudinal axis of the first rod.
