DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

Reference will now be made to the figures wherein like structures will be provided with like reference designations. It is understood that the figures are diagrammatic and schematic representations of some embodiments of the invention, and are not limiting of the present invention, nor are they necessarily drawn to scale.

Referring to FIGS. 1-2, 5-7 and 9-10, the motorcycle trailer has a box trailer bed 1 with four arcuate corners 2. The box trailer bed 1 has a hinged lift lid 6 that opens upwardly on at least one lid hinge 7. The hinged lift lid 6 includes a front top 3 having aerodynamic curvature 4 corresponding to aerodynamic curvature 4 of front arcuate corners and a rear top 5 having aerodynamic curvature 4 corresponding to aerodynamic curvature 4 of rear aerodynamic corners. A gas pressurized lifting shocks 41 shown in FIGS. 9-10 can be attached to the hinged lift lid 6 and a top of a roadway side 9 of a side wall 23 for assisting in lifting and holding the hinged lift lid 6 open. A lid latch 10 is positioned on an off-road side 9 of the box trailer bed 1 hinged lift lid 6 for fastening and unfastening the hinged lift lid 6 selectively from the off-road side 9 of the box trailer bed 1. A selection of known latches can be employed. Some can be positioned on the hinged lift lid 6 for grasping it. Others can be positioned on a top of an off-road side wall 23 for allowing the gas pressurized lifting shocks 41 to open the hinged lift lid 6.

A roadway side 8 of the box trailer bed 1 is a side adjacent to a road with the motorcycle trailer parked on a side of the road and facing in a direction of traffic travel in an adjacent traffic lane of the road. An off-road side 9 of the box trailer bed 1 is an opposite side for access to the hinged lift lid 6 on an opposite side from traffic travel on the road.

The hinged lift lid 6 has lid curvature 11 corresponding to the aerodynamic curvature 4 of the front top 3 and the aerodynamic curvature of the rear top 6 of the box trailer bed 1. Top corners of the box trailer bed 1 have curvature to match side corners.

The box trailer bed 1 is affixed to a trailer frame 12 that can be made of metal rods that preferably are welded together and heat-treated for normalizing and heat-strengthening weldments and the metal rods. Suitable heat treatment of welded frame structure can maximize strength per weight of the trailer frame 12.

Referring to FIGS. 3-4, a road-side wheel 13 is suspended from the roadway side 8 of the trailer frame 12 with a road-side spring member 14. An off-road-side wheel 15 is suspended from the off-road side 9 of the trailer frame 12 with an off-road-side spring member 16. A selection of known spring systems can be utilized. FIG. 3 shows a torsion-spring system with the road-side spring member 14 and the off-road-side spring member 16 suspended from a torsion rod 32. FIG. 4 shows a leaf-spring system with leaf-spring members 33 suspended from a rectangular rod 34. Optionally, but not preferably, the wheels can be suspended without springs.

Referring to FIGS. 1-4, 7 and 11, a trailer tongue 17 is extended from a body front 18 of the trailer frame 12. The trailer tongue 17 is mounted with rubber mounts 35 to stop the harmonics created by the road and operating motorcycle. The rubber mounts 35 stop the metal fatigue at the attachment points and stops trailer tongue 17 failures. The rubber mounts 35 also smooth the feel of the trailer when in motion. A rod end bearing 19 is positioned on a front of the trailer tongue 17. A rod end bearing 19 (also known as a heim joint or rose joint), is a mechanical articulating joint. A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a shaft attached. The ball swivel can be ¾ inch or any other desired size to match the size of the ball joint on the motorcycle.

Referring to FIG. 1, a trailer floor 20 is positioned on the trailer frame 12. A selection of known floor systems can be employed. One floor system that is strong, light and durable for floor-impact conditions is plastic reinforced with woven jute. It is also good insulation for the sleeper bed 24.

Referring to FIGS. 1-2 and 5-7, at least legally required trailer lights 21 operable from a towing vehicle are positioned on the box trailer bed 1. The trailer lights 21 can include side lights and rear lights. The rear lights are preferably large and turn-signal operable from a towing vehicle. A road shield 36 is also placed in front of the box trailer bed 1 on the trailer tongue 17. The road shield 36 includes a metal strap attached to the trailer tongue 17 with a clear plastic shield (e.g., it can be clear polycarbonate) attached to the metal strap. The road shield 36 matches the shape of the box trailer bed 1 (including arcuate corners 2).

Referring to FIGS. 1-4 and 7, a detachable cooler rack 27 can be positioned on the trailer tongue 17. The detachable cooler rack 27 can be removed from the trailer tongue 17 and placed inside the cargo bed 22. A preferred detachable cooler rack 27 has short side restrictions 28 and light structure for holding coolers and other select cargo. The detachable cooler rack 27 can be structured to carry light kitchen facilities, food, beverages and other items for travel use without accessing either the cargo bed 22 or the sleeper bed 24. The detachable cooler rack 27 separates sleeping quarters of the sleeper bed 24 from food and outdoor light kitchen facilities.

Referring to FIGS. 1-4 and 5, the box trailer bed 1 includes the cargo bed 22 having side walls 23 extended vertically upward a distance between two feet and four feet from the trailer frame 12. The cargo bed 22 has a length of four-to-six feet and a width of three-to-six feet.

Referring to FIGS. 6-7, the box trailer bed 1 includes a sleeper bed 24 having side walls 23 extended vertically upward a distance between two feet and four feet from the trailer frame 12. The sleeper bed 24 has a length of six-to-eight feet and a width of three-to-six feet.

Referring further to FIGS. 6-7, the sleeper bed 24 can have at least one side window 25 preferably being tinted and ventable on at least one end of the sleeper bed 24. The sleeper bed 24 also has an entrance door 26 on at least the off-road side 9 of the sleeper bed 24.

Referring to FIGS. 1-7, the box trailer bed 1 and the hinged lift lid 6 can be made of a selection of materials. Included can be cut and shaped aluminum sheet metal and reinforced plastic. Woven jute of a suitable weight and grade has particularly high impact and tensile strengths with high durability for trailer use conditions. It has higher impact strength that glass fibers and provides more insulated comfort than either aluminum or fiberglass.

Referring to FIGS. 1-4 and 6-7, a rear bumper 29 can be attached to the trailer frame 12.

Referring to FIGS. 3-4 and 8, a spare-wheel compartment 30 can be located in the cargo bed 22. The spare-wheel compartment 30 has a cover 31 or lid which separates the spare-wheel compartment 30 from the cargo in the cargo bed 22. Other items such as a tire wrench, tools, tire pump, etc. can be stored within the spare-wheel compartment 30.

The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
