Abstract

A water paddle comprising a first shaft having a blade end and a free end and a second shaft having a blade end and a free end, a first cog collar located on an exterior surface of first shaft and having a first set of teeth extending radially from a mating end of first cog collar and accessible to the user's fingers, a second cog collar located on an exterior surface of second shaft and having a second set of teeth extending radially from a mating end of second cog collar and accessible to the user's fingers, second set of teeth mateable with first set of teeth to prevent rotational movement between shafts, a ferrule extending from the free end of second shaft, a clip lip member located on an interior surface of the ferrule, and a spring tab mechanism located within an interior surface of first shaft and includes a body having corresponding resilient arms each having a displaceable tab supported thereon engageable with a set of push button holes located on first shaft.

Dependent claims

An adjustable double bladed water paddle comprising:

a first paddle shaft having a paddle blade end and a free end and a second paddle shaft having a blade end and a free end;
a first cog collar located on an exterior surface of the first paddle shaft proximal the free end of the first paddle shaft, the first cog collar having a first set of teeth extending radially from a mating end of the first cog collar proximal the free end of said first shaft and accessible to the user's fingers;
a second cog collar located on an exterior surface of the second paddle shaft proximal the free end of the second paddle shaft, the second cog collar having a second set of teeth extending radially from a mating end of the second cog collar proximal the free end of said second shaft and accessible to the user's fingers, the second set of teeth mateable with the first set of teeth to prevent rotational movement between said paddle shafts;
a ferrule extending from the free end of the second paddle shaft, the ferrule having a free end with the second collar located between the paddle blade and the free end of the ferrule;
a clip lip member located on an interior surface of the ferrule proximal the free end of the ferrule;
and
a spring tab mechanism located within an interior surface of the first paddle shaft and spaced downstream from the first cog collar, the spring tab mechanism having a body that includes a set of corresponding resilient arms each having a displaceable tab supported thereon for engagement with a set of push button holes located on the first paddle shaft to provide positive connection confirmation and prevent linear movement between said paddle shafts while providing for a dual-button release system, each resilient arm having a catch member for engagement with the clip lip member to lockingly secure the first paddle shaft with the second paddle shaft to further prevent linear movement between said paddle shafts.

An adjustable double bladed water paddle comprising:

a first paddle shaft having a paddle blade end and a free end and a second paddle shaft having a blade end and a free end;
a first cog collar located on an exterior surface of the first paddle shaft proximal the free end of the first paddle shaft, the first cog collar having a sleeve extending from an end of the first cog collar;
a first set of teeth located circumferentially on an interior surface of the sleeve end accessible to the user's fingers,
a second cog collar located on an exterior surface of the second paddle shaft proximal the free end of the second paddle shaft, the second cog collar having a tapering end;
a second set of teeth located circumferentially on an exterior surface of the tampering end of the second cog collar and accessible to the user's fingers, the second set of teeth mateable with the first of set teeth of the first cog collar to prevent rotational movement between said paddle shafts;
a ferrule extending from the free end of the second paddle shaft, the ferrule having a free end with the second cog collar located between the paddle blade and the free end of the ferrule;
a clip lip member located on an interior surface of the ferrule proximal the free end of the ferrule;
and
a spring tab mechanism located within an interior surface of the first paddle shaft and spaced downstream from the first cog collar, the spring tab mechanism having a body that includes a set of corresponding resilient arms each having a displaceable tab supported thereon for engagement with a set of push button holes located on the first paddle shaft to provide positive visual connection confirmation and prevent linear movement between said paddle shafts while providing for a dual-button release system, each resilient arm having a catch member for engagement with the clip lip member to lockingly secure the first paddle shaft with the second paddle shaft to further prevent linear movement between said paddle shafts.
