Abstract:
1. An adjustable paddle suitable for use with a kayak or watercraft, said paddle extending along a longitudinal axis and comprising: (a) a first paddle member, said first paddle member having a first blade and a first tubular shaft extending from said first blade and having a first end portion provided with a longitudinal slit; (b) a second paddle member, said second paddle member having a second blade and a second tubular shaft extending from said second blade and having a second end portion that is engageable within said first end portion; (c) a sleeve mounted on said first end portion, said sleeve comprising a longitudinal slit located above said longitudinal slit of said first end portion; and (d) a lever extending along a curvature from a proximal end to a distal end, said proximal end being pivotably mounted on said sleeve, said lever comprising a lengthwise extending chamber having an opening provided on an upper wall of said lever and a closed end located remote from said opening and wherein said chamber communicates with a passage extending towards an entry located at said distal end; wherein said lever is movable between a first position, wherein said lever exerts pressure on said sleeve for closing said slits of said first end portion and sleeve such that said first and second paddle members are secured together, and a second position, wherein said lever no longer exerts pressure on said sleeve for allowing either one or both longitudinal and rotational movements of said second paddle member relative to said first paddle member such that length of said paddle and orientation of said second blade relative to said first blade can be adjusted by a user; and wherein, in said second position, said distal end of said lever is accessible by the mouth of the user for allowing the user to blow in said entry for generating an airstream within said passage and said chamber such that sound is produced when said airstream emerges from said opening.
