Abstract
A trailer pontoon bottom has built in wheels designed to fold under the trailer pontoon to be clear of the water and to extend out and lock for land use and be clear of the pontoons. A pair of swing arms each having a first end attached to an inside axial hub of the wheel are designed to rotate on a boss of the first end. A second end of the swing arm is configured to rotate a maximum of 90 degrees from its folded position into a trailer position. An axis parallel to a back end of the trailer pontoon is configured to attach to each of the pair of swing arms at a respective pivot located a swing arm distance from an edge of the trailer pontoon. The axis is rotatable by less than 90 degrees to enable each wheel to retract against a suspension bumper.
Claims19
A trailer pontoon device, comprising:
- a plurality of wheel retracting mechanisms and a wheel for each mechanism thereof for a land operation, each retracting mechanism and the respective wheel thereof configured to retract under a deck of the trailer pontoon device for water operation,
- wherein each retracting mechanism is configured to retract its respective wheel in an arc orthogonal to a rotation of each wheel;
- and
- a placement of each wheel against a respective suspension bumper and an axis rotation against the bumper is limited to less than 90 degrees actuated and limited by an electronically controlled hydraulics.
A trailer pontoon apparatus, comprising:
- a trailer pontoon deck configured to receive a wheel folded under the bottom of the trailer pontoon deck;
- a pair of swing arms each having a first end attached to an inside axial hub of the wheel configured to rotate on a boss of the first end, a second end of the swing arm configured to rotate a maximum of 90 degrees from its folded position;
- an axis parallel to a back end of the trailer pontoon and configured to attach to each of the pair of swing arms at a respective pivot, the axis rotatable by less than 90 degrees to enable each wheel to retract against a suspension bumper;
- and
- a retractable trailer tongue configured to slide in and out of a recess in the trailer pontoon bottom and lock in a trailer position and lock in a retracted position, wherein a sliding action and a locking action thereof are based on a dual hydraulic piston action on the retractable trailer tongue.
A trailer pontoon system, comprising:
- a trailer pontoon bottom configured to receive a wheel folded under the bottom of the trailer pontoon so that a cover on the wheel is hydrodynamically flush with the bottom thereof;
- a pair of swing arms each having a first end attached to an inside axial hub of the wheel configured to rotate on a boss of the first end, a second end of the swing arm configured to rotate a maximum of 90 degrees from its folded position in a respective semicircular depression into a trailer position;
- an axis parallel to a back end of the trailer pontoon and configured to attach to each of the pair of swing arms at a respective pivot located a swing arm distance from an edge of the trailer pontoon, the axis rotatable by less than 90 degrees to enable each wheel to retract against a suspension bumper;
- a retractable trailer tongue configured to slide in and out of a recess in the trailer pontoon bottom and lock in a trailer position and lock in a retracted position, wherein a sliding action and a locking action thereof are based on a dual hydraulic piston action on the retractable trailer tongue;
- and
- a plurality of electronically controlled signal lights disposed on both outside edges of the trailer pontoon back end, the signal lights each having esthetic lens's configured to hide the lights during water operation.
