Abstract
An adjustable roller bunk apparatus and system for use with different size watercraft trailers. The roller bunk system can adjust to fit on all size trailers, can also adjust positioning to receive different angled hulls of watercrafts and prevents torque on the roller bunk system generally caused as a result of a force applied by weight of a watercraft on rollers attached to a roller bunk.
Claims9
An adjustable roller bunk system for a watercraft trailer, comprising:
- a pair of roller bunks each including a plurality of roller axles extending from one side thereof;
- a roller rotatably disposed on each of the plurality of roller axles;
- at least two torque prevention brackets slidably attached at a top portion thereof and at a first half thereof to each roller bunk such that a second half of each torque prevention bracket extends outward from the roller bunk in a same direction as the roller axles, each of the at least two torque prevention brackets including:
- an attachment device to slidably attach the roller bunk to the top portion and first half thereof;
- an extension member disposed at the second half thereof and extending from a bottom portion thereof, the extension member including a single hole extending through a middle portion to receive a bolt therethrough to adjustably attach to a trailer to align the rollers with various shaped watercraft hulls, and being in alignment with the plurality of corresponding rollers such that all weight applied to the rollers directly transfers to the second half of the torque prevention bracket and the extension member to prevent torque from being applied to the corresponding roller bunk;
- and
- a bolt extending through the hole in the extension member and configured to adjustably attach the extension member to an attachment member on a watercraft trailer.

A roller bunk apparatus configured to be attached to a watercraft trailer, comprising:
- an elongated roller bunk including a plurality of roller axles extending from one side thereof;
- a roller rotatably disposed on each of the plurality of roller axles;
- at least two torque prevention brackets slidably attached at a top portion thereof and at a first half thereof to the roller bunk such that a second half of each torque prevention bracket extends outward from the roller bunk in a same direction as the plurality of roller axles, each of the at least two torque prevention brackets including:
- an attachment device to slidably attach the roller bunk to the top portion and first half thereof;
- and
- an extension member disposed at the second half thereof and extending from a bottom portion thereof, the extension member including a single hole extending through a middle portion to adjustably attach to a watercraft trailer to align the rollers with various shaped watercraft hulls, the second half of the torque prevention bracket and corresponding extension member configured to be disposed in a same line as the rollers and in parallel with the corresponding elongated roller bunk such that weight applied to the rollers transfers directly to the second half of the torque prevention bracket and the extension member to prevent torque from being applied to the corresponding roller bunk.
