DETAILED DESCRIPTION

In general, the subject matter herein describes a trailer that can be used for camping. In one embodiment, the trailer is a teardrop-style camping trailer. As used herein, a teardrop-style camping trailer may refer to a streamlined, compact, lightweight, trailer that gets its name from its teardrop profile. Teardrop-style camping trailers provide an alternative to large, cumbersome RVs that limit access to different areas and experiences. In recent years, this minimalist product has found newcomers looking to upgrade from tent-camping, but not limit their experiences by the bulk and cheap quality/aesthetic of the traditional RV. The shift has gone from “RV-ing” to “Overlanding,” and a new generation of vehicles are necessary to support the industry.

As used herein, “Overlanding” describes self-reliant adventure travel to remote destinations where the journey is the primary goal. Typically, but not exclusively, accommodated by mechanized off-highway capable transport where the principal form of lodging is camping. While expedition is defined as a journey with a purpose, overlanding sees the journey as the purpose.

Traditional small campers are made with materials that require slow manufacturing methods (e.g., plywood core, aluminum exterior, exposed fasteners) and are hard to build rugged enough to withstand the elements for years. Conventional solutions on the market are either built with inferior form, function, or antiquated materials and processes.

In addition to the cabin construction, the frame and suspension of conventional trailers in this industry are often leaf-spring design or rubber torsion axles that are ill-equipped to stand up to the rigors of off-road travel.

Conventional solutions for building a trailer that can withstand Overlanding's demands include over-building, often using excessive amounts of heavy metals or redundant body construction that adds unnecessary weight to the unit, making it cumbersome (and in many cases impossible) to pull with common tow vehicles.

The subject matter disclosed herein describes an apparatus for an off-road camper trailer that improves upon conventional teardrop-style camping trailers. In one embodiment, the apparatus includes a monocoque trailer body made of layers of fiberglass with a low-density polyethylene (“PET”) core creating an insulated and rigid trailer body. In one embodiment, the trailer body is formed using a vacuum bag/infused fiberglass manufacturing process to create a strong, lightweight, aesthetically unique, and functionally superior trailer body. The insulated body houses the components and accessories needed for overlanding (e.g., water, air, heat, power, refrigeration, storage) within the internal structure of the body, reducing risk of exposure/damage, and allowing unlimited four-season use.

In one embodiment, the trailer body is mounted to a light-weight frame. The frame, in one embodiment, includes a frame and a trailing arm style suspension that enables high clearance and superior damped suspension for travel on inconsistent terrain.

In one embodiment, the body further comprises one or more entry door openings, a rear galley hatch opening, and a stargazing window opening. In one embodiment, the entry door openings and the galley hatch opening include a return flanged mechanical gutter system built into the body such that any water that enters the gutter is directed down and away from the trailer.

In one embodiment, customer-centric add-ons are installed including, for example, a full queen-sized bed, heater interior storage, a full kitchen galley with sink, stove, and cooled food storage, as well as mounted solar panels and functional roof racks that make the trailer incredibly capable for its size and weight.

Thus, the subject matter herein describes a trailer that is a minimal home on wheels, able to follow the user's tow vehicle wherever it goes, making camp setup easy and convenient. Integrated storage allows the user to take more on their trips and have less setup time when they get there, ultimately allowing easier and safer access to more places for individuals and families who want the adventure of camping and the convenience of RVing.

FIGS. 1A and 1B depict perspective views of embodiments of a camping trailer 100. In one embodiment, a monocoque trailer body 102 or shell is coupled to a trailer frame 104. As used herein, a monocoque body or shell may refer to a structural system in which loads are supported by an object's external skin. In one embodiment, the monocoque trailer body 102 is coupled to the frame 104, e.g., via fasteners, adhesives, clips, snaps, or a combination thereof. In one embodiment, the trailer body 102 is molded, formed, manufactured, or otherwise made from a plurality of material layers. The layers may include a plurality of fiberglass matting that has a low-density polyethylene terephthalate (“PET”) core positioned between an inner layer and an outer layer of the plurality of layers of fiberglass matting such that the body is structurally rigid and insulated.

In such an embodiment, the trailer body 102 is formed by creating a master body mold by layering the plurality of fiberglass matting layers and the PET core, injecting the master body mold with resin, vacuum sealing the master body mold, and curing the master body mold for a predetermined period of time.

In certain embodiments, at least one accessory point is molded into the body. An accessory point, as used herein, may be an area or portion of the external or internal surface of the body 102 that allows for attaching, coupling, connecting, hanging, or the like various accessors to the body 102. In certain embodiments, at least one accessory point includes one or more of a magnet, a hook, an eye, a clip, and/or the like that can be used to attach different accessories such as flashlights, phones or other devices, hats, clothing, bags, cooking accessories, or the like to the body 102. The accessory point may include a portion of the body that is molded where an attachment device can be installed such as a hook, magnet, or the like. In other embodiments, attachment devices may be installed during the molding/forming process (e.g., a hook may be installed in the body during the molding/forming process).

In one embodiment, one or more accesses or entryways are molded into the body 102. The one or more accesses may include doors, windows, ports, or the like, which may be selectively opened and closed. In such an embodiment, a plurality of return flange mechanical gutters for each of the at least one accesses is molded into the body 102. As used herein, the plurality of return flange mechanical gutters are configured to capture moisture at an access/pre-formed point and direct it away from the trailer without additional sealing materials around the at least one access, as described in detail below with reference to FIG. 5.

The body 102 may be formed or molded to form/shape various compartments, accesses, or the like located within an interior of the body 102 and/or on an exterior of the body 102. For instance, a storage compartment 110 may be formed towards the front of the body 102 and towards the tongue of the frame 104. Further, the body 102 may form an interior cabin, a rear galley, a rear galley access 108, a window 112, a roof rack system 120 that includes one or more elongated protrusions, and a roof access.

In one embodiment, a trailer hitch 106 allows the trailer 100 to be towed by a car or truck. In certain embodiments, two oversized, all-terrain or offroad tires 118 are coupled to an axle that is mounted to the frame 104 and provide traction and high clearance to enable the trailer 100 to pass over uneven surfaces. In one embodiment, a fender 116 is coupled to each side of the trailer frame 104 to protect the tires 118, to act as a step, or to act as a table extension.

In one embodiment, a storage door provides access to the storage compartment 110. In one embodiment, an entry door 114 provides access to an interior of the trailer body 102. A galley door 108, in one embodiment, provides access to a rear galley. In one embodiment, a window 112 allows for light to enter the interior of the trailer. One or more elongated protrusions 120, in one embodiment, on the roof allow for items such as a roof rack to be mounted to the roof. In certain embodiments, an interior edge of the windows 112, entry doors 114, or the like are lined with magnetic material for attaching accessories along the windows 112 or entry doors 14, including screens, curtains, or the like that include corresponding magnetic material along their edges.

FIGS. 1C and 1D depict left and right side views, respectively, of an embodiment of the trailer 100, described above with reference to FIGS. 1A and 1B.

FIG. 2A depicts one embodiment of the frame 104. In one embodiment, the frame 104 is made of laser-cut, 2×1-inch tube steel then hot-dip galvanized, for added protection against external environmental elements. One of skill in the art will recognize, in light of this disclosure, that various sizes and materials may be used for the frame 104, such as aluminum.

In one embodiment, the frame 104 includes various mounting points for attaching different accessories to customize the trailer 100. For instance, the frame 104 may include mounting points for rock rails, steps, extra receiver tubes, and/or the like. The mounting points may be shaped to receive accessories that include correspondingly shaped attachment points, e.g., square metal tubing (similar to a receiver hitch), and corresponding holes/openings for securing the accessories with pins.

The fenders 116 may be bolted to the frame 104 and inset into the wheel-well, e.g., by about six inches, which minimizes protrusion and maximizes usable interior space. The frame 104 may include a rear hitch receiving tube 202 for mounting a hitch for pulling an additional trailer, attaching a hitch-mounted cargo rack, a bike rack, or the like. Furthermore, a trailing arm suspension system 170 may be coupled to the frame 104 to provide independent suspension to each wheel/tire coupled to the frame 104, as described in more detail below.

FIG. 2B depicts one embodiment of the frame 104 with a floor mold 204 attached, e.g., bolted to the frame 104. In one embodiment, the floor mold 204 forms the floor of the body 102 that is coupled to the frame 104 to form the complete trailer 100. In certain embodiments, the floor mold 204 is made or manufactured in the same manner as the monocoque trailer body 102, e.g., may be made of multiple layers of fiberglass material. Other types of materials may be used for the flooring, including wood, aluminum, steel, vinyl, and/or the like.

FIG. 3A depicts various internal structural and mechanical components of the trailer 100, which are mounted to the frame 104 and/or the floor mold 204. In one embodiment, the internal structures are made of high-density polyethylene (“HDPE”) and lightweight honeycomb composite that is computer numerical control (“CNC”) precision cut with mortise and tenon construction for added strength. The internal structural components may divide an interior of the body 102 into different areas or sections such as the storage compartment 110, the main cabin area, a mechanical area 302, and a rear galley area 304.

In one embodiment, the mechanical area 302 may include various mechanical parts such as one or more batteries (or other power sources) and/or other electrical components; heating, ventilation, and air conditioning (“HVAC”) components; a water tank and other plumbing components; and/or the like.

In one embodiment, one or more rails 1402 are molded into, bolted to, or otherwise mechanically attached to the elongated protrusions 120 that are formed in the body 102. The rails 1402 provide an interface to receive roof rack mounting rails 1204, which are used to secure cargo to the roof of the trailer body 102.

FIGS. 15A and 15B show an overhead view of the trailer 100 and an underside view of the trailer 100, respectively. In one embodiment, the unique structure of the trailer frame 104 is shown. As described above, in one embodiment, the trailer frame 104 includes a hot-dip galvanized tube steel frame. In one embodiment, the monocoque trailer body 102 bolts or otherwise mechanically couples directly to the trailer frame 104, adding stiffness without adding unnecessary weight. In one embodiment, the fenders 116 are bolted into the trailer frame 104.

FIG. 16 depicts one embodiment of a method 1600 for forming a trailer body. In one embodiment, the method 1600 begins and creates 1602 a master body mold by layering the plurality of fiberglass matting layers and the PET core (e.g., which may be made of recycled milk cartons). In one embodiment, the method 1600 injects 1604 the master body mold with resin. In one embodiment, the method 1600 vacuum seals 1606 the master body mold. In one embodiment, the method 1600 cures 1608 the master body mold for a predetermined period of time, and the method 1600 ends.

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.

Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

As used herein, a list with a conjunction of “and/or” includes any single item in the list or a combination of items in the list. For example, a list of A, B and/or C includes only A, only B, only C, a combination of A and B, a combination of B and C, a combination of A and C or a combination of A, B and C. As used herein, a list using the terminology “one or more of” includes any single item in the list or a combination of items in the list. For example, one or more of A, B and C includes only A, only B, only C, a combination of A and B, a combination of B and C, a combination of A and C or a combination of A, B and C. As used herein, a list using the terminology “one of” includes one and only one of any single item in the list. For example, “one of A, B and C” includes only A, only B or only C and excludes combinations of A, B and C. As used herein, “a member selected from the group consisting of A, B, and C,” includes one and only one of A, B, or C, and excludes combinations of A, B, and C. As used herein, “a member selected from the group consisting of A, B, and C and combinations thereof” includes only A, only B, only C, a combination of A and B, a combination of B and C, a combination of A and C or a combination of A, B and C.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. 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.
