Folding toy hauler tent trailer

[0001] This application is based on and claims the priority of U.S. Provisional Patent Application No. 60/599,845, filed on Aug. 6, 2004, which is hereby expressly incorporated by reference herein in its entirety.

[0002] 1. Field of the Invention

[0003] The present application generally relates to trailers. More specifically, the present application relates to a folding tent trailer for hauling recreational vehicles.

[0004] 2. Description of the Related Art

[0005] Folding trailers are small recreational vehicles that can be folded down for storage and travel and can be raised to provide a living space. The folding trailers are designed to be relatively low profile and towable by medium sized vehicles. They are typically lightweight and inexpensive with limited features.

[0006] Toy haulers are relatively large travel trailers that have been designed to carry off-road vehicles inside the rear cargo area of the trailer. When the vehicles are unloaded from the trailer, the area converts to a living space. Toy haulers typically have moderate to high-end amenities and are heavy duty. They usually have multiple axles and are often towed by bigger trucks or sport utility vehicles.

[0007] Traditional folding trailers are small enough to be stored within a typical garage, but are not adapted to carry recreational vehicles. Traditional folding trailers are too light-weight to carry large loads. Their tops are not reinforced and they typically have light-duty axles and chassis designs. Additionally, even if a recreational vehicle could be supported on top of a typical folding trailer, the combined height of the trailer and the vehicle would be too tall to fit within a garage.

[0008] Typical toy haulers are designed to carry off-road vehicles, but are generally too large to fit in a garage. Many people have difficulty storing the toy haulers; most store them in special facilities away from their homes. Additionally, the off-road vehicles are stored in the living area within the trailer. This negatively affects the comfort of the living area and limits the amenities provided. For example, oil and gas residue and odors tend to remain in the living area. Amenities in the cargo area are usually limited to temporary, removable habitation structures, such as for example, folding seats and beds.

[0009] The invention disclosed herein includes the realization that trailer systems can be improved to haul recreational vehicles and to provide a more comfortable living area or habitation space. In some embodiments, a platform supports a recreational vehicle above the trailer when the platform is in a lowered position, and the platform functions as a roof over a habitation space when in a raised position. It is further recognized that such a trailer system preferably is configured such that it fits within a garage with the recreational vehicle mounted thereon.

[0010] Thus, in accordance with another aspect of the invention disclosed herein, a trailer comprises a trailer body having a side portion. A trailer cover is coupled to the trailer body and is movable between a first position and a second position relative to the trailer body. The trailer cover in the first position is sufficiently rigid to support a recreational vehicle above the side portion of the trailer body.

A folding toy hauler tent trailer represents an application for which many features, aspects and advantages of the present invention provide particular advantages. Nevertheless, certain features, aspects and advantages of the present invention can be used with other types of trailers.

[0044] As shown in FIGS. 1–6, in one preferred embodiment of the invention, a trailer 50 comprises a trailer body 52 having a side portion 54. A trailer cover 56 is coupled to the trailer body 52 and is movable between a first position relative to the trailer body 52, as shown, for example, in FIGS. 1–3, and a second position relative to the trailer body 52, as shown, for example, in FIG. 6. With reference to FIGS. 1–3, the trailer cover 56 in the first position is sufficiently rigid to support one or more recreational vehicles 58 above the side portion 54 of the trailer body 52. In the second position, the trailer cover 56 forms at least a portion of a roof and is spaced from the trailer body 52 a sufficient distance to at least partially define a habitation space 66 below the trailer cover 56, as shown, for example, in FIG. 6.

[0045] With reference to FIGS. 7–15, another preferred embodiment of a trailer is illustrated having a trailer cover 56 with a first portion configured to be higher than a second portion. FIGS. 16–17 illustrate an additional preferred trailer embodiment having a trailer cover 56 with a first portion configured to be higher than a second portion. With reference to FIGS. 18–19 a trailer is illustrated having a trailer cover 56 with a first portion configured to be higher than a second portion at least in a lowered configuration, as will be described further below. FIGS. 20–23 illustrate other additional embodiments. Many of the structures, features, aspects and advantages that are described below with respect to one embodiment are also applicable to other embodiments shown or described herein. Accordingly, like reference numerals will be used to designate like structures throughout the different embodiments unless otherwise noted.

[0046] With continued reference to FIGS. 1–6, the trailer body 52 preferably has one or more side portions 54. The side portions 54 are coupled to a floor or base portion 60 to define a lower portion of the trailer 50. The side portions 54 comprise one or more side walls 62. The trailer cover 56 in the first position is preferably supported on at least one of the side walls 62 of the trailer body 52 or on one or more supports that extend from one of the side walls 62. As used herein, the term “side portions” includes the side walls, the front wall, the rear wall, the frame portions of the walls, any supports extending from any walls, and can also include portions of walls. The first position preferably is a lowered position wherein the trailer cover 56 is positioned near a top portion of the trailer body 52. In some embodiments, the trailer cover 56 preferably rests on, and is at least partially supported by, the side walls 62 of the trailer body 52. When the trailer cover is positioned above a side portion of the trailer body, the trailer cover is located generally above at least a portion of one or more of the front, rear, side, or other walls of the trailer body, but not necessarily above every portion of one or more of the walls. As shown in the illustrated embodiment, the trailer cover 56 is spaced from the base portion 60 of the trailer body 52, as will be described further below.

[0047] As described above, the trailer cover 56 in the first position preferably is sufficiently rigid to support one or more recreational vehicles 58. The terms “recreational vehicle” as used herein refer to relatively heavy vehicles, such as for example, but without limitation, motorcycles, ATV'S, personal watercraft, or other motorsports products or similar vehicles that would be too heavy to be supported atop a conventional folding tent trailer. The trailer cover 56 preferably comprises structural members spanning from one side of the trailer cover 56 to another to provide support for heavy loads. In some embodiments, structural members can extend from a left side of the trailer cover to the right side of the trailer cover, e.g., the structural members being generally parallel to one another. In some embodiments, structural members can extend from the front portion of the trailer cover to the rear portion of the trailer cover, e.g., the structural members being generally parallel to one another. In some embodiments, structural members can extend between side portions of the cover and between front and rear portions of the cover, e.g., the structural members can form a structural grid with some structural members being generally parallel to one another and some structural members being generally perpendicular to one another. The structural members can be, for example, rods, bars, struts, beams, and/or plates. In some embodiments plates can include diamond plate materials. Portions of the trailer cover 56 preferably are constructed with metal. Other materials or combinations of materials, including, for example, composite materials can be used in forming the trailer cover 56. The trailer cover 56 preferably comprises a reinforced support structure; however, the trailer cover 56 preferably is light enough to be raised using a lift mechanism 64 to a suitable height to provide a habitation space 66.

[0048] In some embodiments, the trailer cover 56 preferably comprises structural members configured such that the trailer cover supports a load greater than about 300 pounds (136.1 kg) in one or more positions. In some embodiments, the trailer cover 56 preferably supports a load greater than about 500 pounds (226.8 kg). In some embodiments, the trailer cover 56 preferably supports a load greater than about 700 pounds (317.5 kg). In some embodiments, the trailer cover 56 preferably supports a load greater than about 900 pounds (408.2 kg) or more. Still other embodiments are contemplated, e.g., including intermediate ranges.

[0049] With reference to FIGS. 4–6, the trailer cover 56 is movable from the first position to the second position. The second position preferably is a raised position. In the second position, the trailer cover 56 is spaced from a top portion of the trailer body 52. The trailer cover 56 preferably is raised using a lift mechanism 64 as will be described further below.

The trailer cover 56 in the first position preferably is at least partially, e.g., indirectly, supported by the frame 70. In one embodiment, the frame 70 indirectly supports the trailer cover 56 through one or more of the side portions 54, one or more interior support struts 72, and/or one or more habitation structures 68.

[0052] In some embodiments, the trailer body 52 comprises support struts 72 to at least partially support the trailer cover 56 when it is in the first position. One embodiment having a support strut is illustrated in FIG. 15, which will be described further below. Support struts can be used in connection with other embodiments shown or described herein. The support struts 72 can be any suitable structure for supporting a portion of the trailer cover 56. In some embodiments, the support struts 72 are configured to support a central portion of the trailer cover 56. The support struts 72 preferably are configured such that when the trailer cover 56 is in the second position the support struts 72 tend not to significantly obstruct the use of the habitation space 66. In some embodiments, such as, for example, the embodiment illustrated in FIGS. 7–15, support struts 72 can be movable (e.g., folding to the side or into the base), removable, reconfigurable, or collapsible (e.g., telescoping). With reference to FIG. 15, support struts 72 also can be configured for use with, or as portions of, habitation structures 68. For example, a table has a support strut 72, e.g., a sturdy support tube, that can be mounted in the middle of the floor to at least partially support the trailer cover 56 when it is in the first position. When the trailer cover 56 is moved to the second position, the support strut 72 can be repositioned toward a side portion 54 of the trailer body 52 to support the table for use within the habitation space 66.

[0053] With reference to FIGS. 4–6, the trailer 50 comprises a tent portion 74. In some embodiments, the tent portion 74 comprises a fabric, cloth, mesh or other flexible material to generally define at least a portion of a habitation space when placed in an expanded configuration. In some embodiments, the tent portion comprises one or more window features. The tent portion 74 is positioned within the trailer body 52 such that the tent portion 74 is in a collapsed condition when the trailer cover 56 is in the first position. The tent portion 74 preferably is coupled with the trailer body 52 and the trailer cover 56 and is deployable when the trailer cover 56 is in the second position to at least partially define a habitation space 66.

[0054] As shown, for example, in the embodiment illustrated in FIGS. 7–15, the trailer body 52 preferably comprises habitation structures 68. With reference to FIG. 15, habitation structures 68 preferably include cabinets or other storage compartments 78, tables, benches, beds, doors, refrigerators, stoves, sinks, restroom facilities, countertops, or other structures suitable for enhancing the habitability of a habitation space 66. The trailer body 52 preferably comprises powered habitation devices 76. Powered habitation devices 76, or other power equipment, can include habitation structures 68 that generate power, that comprise a power source, or that can be coupled to a power source for operation, e.g., a generator, a motor, a refrigerator, a stove, an oven, a water pump, an air compressor, a microwave oven, a television, a radio, a light, a heater, or any other powered amenity, feature or accessory. Habitation structures 68 and/or powered habitation devices 76 can be used in connection with other embodiments shown or described herein. Some features and advantages of configurations having powered habitation devices 76 are described further below.

[0055] In some embodiments, the trailer body 52 comprises habitation structures 68 that are convertible from a lowered configuration when the trailer cover 56 is in the first position to a raised configuration when the trailer cover 56 is in the second position. For example, a cabinet can be lowered when the trailer cover 56 is in the first position and the cabinet can be raised for use when the trailer cover 56 forms a portion of the roof of the habitation space 66. In some embodiments, habitation structures 68 are arranged such that the trailer cover 56 in the first position is at least partially supported by one or more habitation structures 68. In some embodiments, habitation structures 68 are fixed in certain positions and designed to support the trailer cover 56 when in the first position. In some embodiments, habitation structures 68 are movable, removable or reconfigurable within the trailer 50 to support the trailer cover 56 in the first position.

[0056] The trailer body 52 preferably comprises one or more storage compartments 78. With reference to FIG. 15, as described above, the trailer cover 56 in the first position preferably is at least partially supported by a storage compartment 78, e.g., a cabinet. With reference to FIGS. 18–19, in some embodiments, a storage compartment 78, e.g., a drawer or removable bin, is accessible from outside the trailer body 52 when the trailer cover 56 is in the first position. In some embodiments, the storage compartment 78 is accessible from outside the trailer body 52 when the trailer cover 56 is in the second position. The storage compartment 78 preferably is accessible from inside the habitation space 66 when the trailer cover 56 is in the second position.

[0057] With reference to FIGS. 1–6, the trailer body 52 preferably comprises at least one axle 80 and a plurality of wheels 82 for supporting the trailer 50. The axle 80 preferably is sufficiently strong to support the load of the trailer 50 and one or more recreational vehicles 58.

As shown in FIGS. 8 and 9, wheel chocks 96 are placed on the vehicle support surface 88 to minimize the risk that the wheels of a recreational vehicle 58 will roll or slide while being towed, moved, or stored. As shown in FIG. 18, one or more rails 98 and/or other stops, e.g., wheel chocks, are positioned on the vehicle support surface 88, preferably near the side edges of the vehicle support surface 88 to maintain the recreational vehicle 58 atop the support surface. As shown in FIGS. 8–10, tie down anchors 100 are placed over portions of the recreational vehicles 58 and coupled with the trailer body 52 or trailer cover 56. With reference to FIG. 18, locks 102 can be provided to secure the recreational vehicle 58 to the trailer 50 for security purposes. Vehicle securement members 94 preferably are adjustable and positionable in various configurations on the trailer cover 56 or body to accommodate a desired number of recreational vehicles 58 mounted on the trailer 50. The vehicle securement members 94 can be configured to secure different types of recreational vehicles 58 or other cargo.

[0071] With reference to FIGS. 7–15, the trailer cover 56 has a first section 104 and a second section 106. As shown, the first section 104 is a front section and the second section 106 is a rear section. The first section 104 preferably is higher than the second section 106 relative to the ground surface 90 supporting the trailer 50 when the trailer cover 56 is in the first position. Recreational vehicles 58 preferably are positioned on the second section 106. In some embodiments, the first section 104 forms an elevated mounting surface to support relatively lighter cargo or gear in a position generally above the surface where the recreational vehicles 58 are mounted. The first section 104 can support or comprise one or more roof-mounted devices 108, e.g., a vent, a fan, an air conditioning unit, an antenna, or other devices preferably mounted in an elevated position, as is illustrated in connection with the embodiment shown in FIGS. 18–19. Positioning the roof-mounted devices 108 on the first section 104 preferably protects them from damage by the recreational vehicles 58. Additionally, the roof-mounted devices 108 preferably are protected from dirt, mud, grease, oil, gasoline, water, or other contaminants associated with the recreational vehicles 58. The first section 104 comprises molded wheel chocks in some embodiments.

[0072] The first and second sections 104, 106 are formed integrally as a unitary roof structure in some embodiments, as is illustrated in the embodiments shown in FIGS. 7–15 and FIGS. 16–17. With reference to FIGS. 7–15, the raised portion of a unitary roof structure acts to enhance the structural integrity of the trailer cover 56. In other embodiments, such as for example, the embodiment illustrated in FIGS. 18–19, the first and second sections 104, 106 are not formed integrally as a unitary roof structure.

[0073] As shown in FIGS. 7–15, 16–17, and 18–19, relatively larger habitation structures 68 or powered habitation devices 76, e.g., a refrigerator, a stove, a water pump, a restroom facility, or other relatively large components, preferably are accommodated generally below the first section 104 of the trailer cover 56. In the embodiment shown in FIGS. 7–15, the side portions 54 of the trailer body 52 have a generally uniform height and the first section 104 of the trailer cover 56 has extended side portions 110 to enclose or cover the habitation structures 68. In another embodiment, shown in FIGS. 16–17, the side portions 54 of the trailer body 52 disposed below the first section 104 of the trailer cover 56 are extended higher than the side portions 54 of the trailer body 52 disposed below the second section 106 of the trailer cover 56. In one embodiment, the first and second sections 104, 106 of the trailer cover 56 preferably are contoured to generally correspond to the shape of the top of the side portions 54 of the trailer body 52 to enclose or cover the habitation structures 68.

[0074] FIGS. 7–15, 16–17, and 18–19, illustrate embodiments wherein the first section 104 is movable between a first height (e.g., a lowered position) and a second height (e.g., a raised position). The first section 104 is movable independent of the second section 106 in some embodiments, such as, for example, in the embodiment shown in FIGS. 18–19. In FIGS. 7–15, 16–17, and 18–19, the second section 106 is movable between a first height (e.g., a lowered position) and a second height (e.g., a raised position). The second section 106 is movable independent of the first section 104 in some embodiments, such as, for example, in the embodiment shown in FIGS. 18–19. In some embodiments, the first and second sections 104, 106 are formed integrally, or can be coupled to move together, as described above and illustrated in the embodiments shown in FIGS. 7–15, and 16–17. As shown in FIGS. 18–19, in some embodiments, the second section 106 is configured to move a first distance independently, and then to move a second distance coupled to the first section 104. For example, the second section 106 can be raised independently to engage the first section 104, and then both sections can be raised together.

[0075] As shown in FIG. 3, the trailer 50 preferably comprises a ramp 112 configured to be coupled to the trailer body 52. In some embodiments, the ramp 112 hangs from the frame 70 below the base portion 60 of the trailer body 52. The ramp 112 is used to load the recreational vehicles 58 on top of the trailer cover 56 while in the first position. In some embodiments, the ramp 112 is also configured to function as a habitation structure 68, such as, for example, a door, a table, or a bed support.

[0076] FIG. 20 is a perspective view of another embodiment of a trailer 200 having a raised front portion 220. The trailer of FIG. 20 is similar to the trailer of FIGS. 18–19, except as described below. As shown in FIG. 20, the front portion 220 of the trailer 200 can be taller than the front portion of the trailer of FIGS. 18–19. In some embodiments, it is desirable to provide a taller front portion 220 of the trailer 200 to provide space for larger components and/or to provide additional storage space. For example, relatively larger habitation structures or powered habitation devices, e.g., a refrigerator, a stove, a water pump, a restroom facility, or other relatively large components may be configured in the taller front portion 220 of the trailer 200. Additionally, the front portion 220 of the trailer 200 can provide some protection for the vehicles stored on the trailer 200 as the trailer 200 is being towed behind a vehicle. In the illustrated embodiment, the trailer 200 also comprises an aircraft style head 216, a folding door 268, a pop-up HVAC unit 208, a pop-up roof 204, 206, a shower portion 210, an enclosed fuel storage portion 276, e.g., propane storage portion, a pull-out step 212, a pull-out cargo storage drawer 278, adjustable tie down points 202, a heavy duty dual axel 284, and an AC hook up 214. The trailer 200 can additionally comprise any one or more of the other features and components described herein.
