Abstract
An adjustable paddle (A) is disclosed which includes an adjustable joint (C) which allows for two handle sections (14, 16) to be fitted together in a desired axial and rotational positions to fix the length of paddle (A) and the relative blade angle settings of blades (18, 20). The adjustable joint includes three concentric shafts (22, 24, 28; and 62, 64, 66) to provide a more rigid joint which is generally wobble-free. Preferably, the concentric shafts are fixed together by a compression lock (30). The compression lock includes an annular compression member (32) and beveled edges (38, 58, 70) affixed on the first handle section and a complimentary beveled surface (34a) on compression nut (34). Tightening of the compression nut forces compression member (32) about the shaft of the second handle section to fit the handle sections together in the desired axial and rotational position. Additionally, a cam lock (26) may also be utilized to alternately lock the handle sections together.
