Abstract

A boat trailer having a multi-wheel supported frame and an extendable tongue which facilitates launching a boat into the water. A tongue member has a rear portion connected to and forwardly extending from the frame and a forward portion adapted for releasable connection to a trailer hitch of a tow vehicle. A tongue extension includes two extension members pivotally connected together to a central connecting member and pivotally connected at a corresponding opposite end of each extension member between the forward and rear portions. The extension members are pivotally movable between the upright side-by-side stored position and the deployed position in end-to-end fashion and longitudinally aligned with the forward and rear portions wherein the effective length of the tongue member is extended by an amount equal to the combined length of the extension members.

Dependent claims

A boat trailer comprising:

a multi-wheel supported frame adapted to support, transport and launch a boat thereatop and therefrom, respectively;
an elongated substantially straight tongue member having a rear portion thereof connected to and forwardly extending from a central point and along a longitudinal axis of said frame and a forward portion adapted at a forward distal end thereof for releasable connection to a trailer hitch of a tow vehicle;
a tongue extension which, when moved from a stored configuration to a deployed configuration, extends the effective length of the tongue member during launching of the boat into the water;
said tongue extension including two elongated extension members pivotally connected together to a central connecting member about spaced transverse pivotal axes and pivotally connected at a corresponding opposite end of each said extension member between said forward portion and said rear portion;
said extension members pivotally movable in an upright plane coplanar with said tongue member between the upright side-by-side stored position and the deployed position in end-to-end fashion substantially longitudinally aligned with said forward and rear portions wherein the effective length of said tongue member is extended or lengthened by an amount substantially equal to the combined length of said extension members.

A boat trailer comprising:

a multi-wheel supported frame adapted to support, transport and launch a boat thereatop and therefrom, respectively;
an elongated substantially straight tongue member having a rear portion thereof connected to and forwardly extending from a central point and along a longitudinal axis of said frame and a forward portion separate from said rear portion adapted at a forward distal end thereof for releasable connection to a trailer hitch of a tow vehicle;
a tongue extension which, when moved from a stored configuration to a deployed configuration, extends the effective length of the tongue member during launching of the boat into the water;
said tongue extension including two elongated straight extension members pivotally connected together to a central connecting member about closely spaced apart transverse pivotal axes and pivotally connected at a corresponding opposite end of each said extension member to said forward portion and said rear portion;
said extension members pivotally movable between the stored upright side-by-side position and the deployed position in end-to-end fashion substantially longitudinally aligned one to another with said forward and rear portions wherein the effective length of said tongue member is extended or lengthened by an amount substantially equal to the combined length of said extension members.
