Abstract

A travel trailer having exterior unitary lower and upper shells, an interior lower shell defining a pre-molded floor and side walls with a seating area, a cabinet for refrigerator and stove top, an opposing bench, a bathroom sink, and defining an aisle centrally therebetween; a shower pan attached to a side wall; an interior upper shell defining a pre-molded ceiling, side walls, and storage areas; a wall defining a door to a bathroom portion; and a wheeled chassis connected to the exterior lower shell with an extending tongue for attaching to a trailer hitch of a motor.

Claims

1. A travel trailer, comprising:

an exterior lower shell and an exterior upper shell, each molded as a single unitary body and configured with a mating edge for overlapping joining of the exterior lower shell and the exterior upper shell, the opposing exterior lower shell and the exterior upper shell each defining a slotted opening extending from the respective edge for a passageway into an interior of the travel trailer;

an interior lower shell received in the exterior lower shell and defining pre-molded floor and side walls, and having a seating area with opposed benches, a cabinet structure configured for receiving a refrigerator and stove top, an opposing bench, and defining an aisle centrally therebetween;

a shower pan seated on the floor and attached to at least one side wall;

an interior upper shell received in the exterior upper shell and defining pre-molded ceiling, opposing side walls, opposing L-shaped walls extending from the ceiling and extending to a respective side wall to define storage areas accessed through selectively operated doors;

a wall defining a second door to separate a bathroom portion; and

a wheeled chassis connected to the exterior lower shell and defining a longitudinally extending tongue configured for attaching to a trailer hitch of a motor vehicle for moving the travel trailer.

2. The travel trailer as recited in claim 1, wherein the chassis comprises:

a pair of spaced-apart longitudinal members; and

a plurality of spaced-apart transverse members attached to the longitudinal members; and

wherein the exterior lower shell defines two U-shaped channels extending longitudinally and aligned for each receiving a respective one of the longitudinal members; and

attachment means for securing the lower shell to the chassis.

3. The travel trailer as recited in claim 2, wherein the attachment means comprises four fastener assemblies for securing the exterior lower shell to the chassis at four points.

4. The travel trailer as recited in claim 3, wherein each fastener assembly comprises:

a bolt having a threaded distal end;

a plate defining an opening for receiving the bolt and seated on a channel of the exterior lower shell; and

the exterior lower shell defining an opening;

a member of the chassis defining an opening,

whereby the bolt received through the aligned openings in the plate, the channel, and the member, receives a nut on the threaded distal end for securing the exterior lower shell to the chassis.

5. The travel trailer as recited in claim 1, further comprising a bathroom assembly received in a portion of the exterior lower shell, having a unitary molded floor, transverse wall defining an opening for a doorway, a second wall extending from side edge of the transverse wall, and a sink.

6. The travel trailer as recited in claim 5, wherein the sink in the bathroom assembly is defined in a surface of a cabinet structure extending from a side wall thereof, said cabinet structure defining an interior storage space accessible through an opening in a side face of thereof.

7. The travel trailer as recited in claim 1, further comprising a rear bumper assembly, comprising:

a back housing having opposing top and bottom plates and a back plate with opposing sides to define a cavity therein and having an open face;

a bumper member pivotably attached to the sides of the back housing, movable from a first position covering the open face and a second position pivoted away from the back housing for access therein through the open face.

8. The travel trailer as recited in claim 7, wherein the back housing includes a valved elongated conduit that communicates with a sanitary waste holding tank, the conduit selectively opened for discharge of the sanitary waste holding tank.

9. The travel trailer as recited in claim 1, wherein the exterior lower shell defines a sub-floor space having spaced-apart frame channels and an intermediate channel;

and further comprising;

a sanitary waste holding tank that communicates with waste water supply connected to at least a sink; and

a fresh water tank that communicates with a fresh water supply connected to at least a sink,

the sanitary waste holding tank and fresh water tank disposed between respective ones of the frame channels and the intermediate channel.

10. The travel trailer as recited in claim 1, further comprising a storage compartment mounted on a tongue of a trailer chassis adjacent a forward surface of the exterior lower shell.

11. The travel trailer as recited in claim 10, wherein the storage compartment further comprises a holding bracket for at least one gas fuel supply tank and a valve for selective communication of a fuel to a fuel using appliance.
