Definitions
- the invention relates to a paddle for a watercraft.
- Such paddles comprise a handle on one of the ends of which a blade is associated, the other end being able to be equipped with a handle or a second blade, depending on the type of activity and/or sport practiced (e )(s).
- paddles which are partially removable and/or retractable, in particular to be able to be transported in or on a backpack.
- Such an arrangement proves to be particularly advantageous in the case of sports activities combining nautical movements with land movements, such as for example packrafting.
- Document US-2 566 023 provides a paddle, the handle of which has two segments each extending between an inner end and an outer end, a blade being reversibly associated with the outer end of a first segment, and the ends internal being equipped with a reversible association device, in order to be able to form - respectively disassemble - the paddle by association - respectively dissociation - of the blade and the segments.
- the paddle when not in use, can be disassembled into three parts - the two segments and the blade -, which makes it possible to limit its size, and thus facilitate its storage and transport.
- the different parts of the paddle become independent of each other, which does not allow them to be easily handled with a view to transporting and/or storing them.
- each of the three disassembled parts must be fixed on specific means of said bag, which is not satisfactory.
- the invention aims to improve the prior art by proposing in particular a paddle having a handle and at least one blade which can be dismantled into several parts when not in use, said paddle incorporating specific means making it possible to facilitate handling and the transport of said disassembled parts.
- the invention proposes a paddle for a nautical craft comprising a handle having at least one segment extending between an internal end and an external end, a blade being associated in a reversible manner on the external end of said segment in order to be able to form - respectively disassemble - the paddle by association - respectively dissociation - of the blade and of said segment, said paddle comprising geometric means formed on the blade and complementary geometric means formed on the segment, said geometric means being arranged to associate said segment on the blade in disassembled configuration.
