Embodiments of the present disclosure relate to a wheeled assembly, an assembly including a wheelless trailer and a wheeled assembly, a method of retrofitting a wheelless trailer with a wheeled assembly.
Automobile trailers are typically hitched to an automobile for transport to a remote location. After hitching the trailer to the automobile, the driver may drive the trailer to the remote location. Many storage trailers and camping trailers are typically large enough to fit one or more adult people, equipment, or other large objects, and may have a length from between 6 to 12 feet behind the automobile. Such trailers commonly require large road-capable wheels for transport. Furthermore, when transporting large trailers, the operator is typically subjected to additional speed and lane restrictions that are not required for vehicles without a trailer. Much smaller storage compartments that may be mounted to a vehicle such as on top or on the rear do not require wheels and do not require speed and lane restrictions. However, such storage compartments do not have enough storage capacity for larger objects such as one or more adult people.

With reference now to the embodiment illustrated in
In the illustrated embodiment, the frame 101 includes a pair of side rails 108, 109 extending longitudinally and parallel or substantially parallel to each other, a front cross member 110 extending transversely between the side rails 108, 109 proximate to the front end of the frame 101, and a rear cross member 111 extending transversely between the side rails 108, 109 proximate to a rear end of the frame 101. Additionally, in one or more embodiments, the configuration (e.g., the shape and size) of the frame 101 is configured to match or substantially match the configuration (e.g., the shape and size) of the trailer that it is designed to support. That is, in one or more embodiments, the “footprint” of the frame 101 is configured to match or substantially match the “footprint” of the trailer that it is designed to support. For instance, in one or more embodiments, the configuration (e.g., the shape and size) of the frame 101 is configured to match or substantially match the configuration (e.g., the shape and size) of structural framework along a base or floor of the trailer that it is designed to support. In one or more embodiments, the trailer may be the extendable compartment trailer disclosed in U.S. application Ser. No. 14/708,137, filed on May 8, 2015 (which issued as U.S. Pat. No. 9,636,958), the entire contents of which are incorporated herein by reference. Accordingly, although in the illustrated embodiment the frame 101 is rectangular, in one or more embodiments, the frame 101 may have any other suitable shape depending, for instance, on the shape of the trailer that it is designed to support. Providing the frame 101 in the same configuration (e.g., size and shape) as the trailer that it is designed to support is configured to minimize or at least reduce the overall storage size of the trailer and the wheeled assembly 100.
In the illustrated embodiment, the frame 101 also includes a pair of flanges 112, 113 extending upwards from the side rails 108, 109, respectively, and longitudinally along at least a portion of outer edges 114, 115 of the side rails 108, 109, respectively. Additionally, in the illustrated embodiment, each of the flanges 112, 113 includes a series of openings 116 (e.g., holes) configured to receive fasteners for securing a trailer to the frame 101 of the wheeled assembly 100. The configuration (e.g., shape, size, arrangement, and number) of the openings 116 is configured to match the configuration (e.g., shape, size, arrangement, and number) of the openings in the trailer that the wheeled assembly 100 is designed to support. However, in one or more embodiments, the configuration of the openings 116 in the flanges 112, 113 may not match the configuration of the openings in the trailer. For instance, in one or more embodiments, the openings 116 in the flanges 112, 113 may elongated openings (e.g., slots) at least a portion of which is configured to overlap with the openings in the trailer, or the openings 116 in the flanges 112, 113 may include two or more different patterns of openings, so that the openings 116 in the flanges 112, 113 may be aligned with a variety of different hole patterns in the trailer (i.e., the openings 116 in the flanges 112, 113 may be “universal” such that the flanges 112, 113 of the frame 101 may be coupled to two or more different types of trailers having different arrangements of openings).
In the illustrated embodiment, a front end of each of the side rails 108, 109 includes a clevis 117, 118, respectively (e.g., a pair of prongs spaced apart by an opening each having an opening). As described in more detail below, the clevises 117, 118 are configured to enable the tongue 104 to rotate (arrow 119) relative to the frame 101 between a deployed position (shown in
In the illustrated embodiment, the tongue 104 includes a cross member 120 and a pair of angled members 121, 122 extending forward and inward from opposite sides of the cross member 120. Forward ends of the angled members 121, 122 are joined together at an apex or a tip. Together, the cross member 120 and the pair of angled members 121, 122 are arranged in a triangular configuration. Additionally, in the illustrated embodiment, the tongue 104 includes a pair of tangs 123, 124 extending rearward from the opposite ends of the cross member 120. The tangs 123, 124 of the tongue 104 are configured to extend into the openings in the clevises 117, 118 of the frame 101. Additionally, the tangs 123, 124 of the tongue 104 each include an opening configured to accommodate a fastener (e.g., a clevis pin). In the illustrated embodiment, the tongue 104 is hingedly (arrow 119) coupled to the frame 101 by inserting the tangs 123, 124 into the openings of the clevises 117, 118 and, for each tang 123, 124 and its corresponding clevis 117, 118, inserting a fastener (e.g., a clevis pin) through the openings in the clevis 117, 118 and the corresponding openings in the tang 123, 124.
The tongue 104 also includes a longitudinal member 125 coupled to the cross member 120 and the angled members 121, 122. In the illustrated embodiment, the longitudinal member 125 is laterally centered on the tongue 104 such that the longitudinal member 125 is coupled to a central portion of the cross member 120 and the apex of the angled members 121, 122. Additionally, in the illustrated embodiment, the longitudinal member 125 is coupled to the underside of the cross member 120 and the angled members 121, 122. Accordingly, when the trailer 200 is coupled to the frame 101 and the tongue 104 is in the stowed position, as illustrated in
Additionally, in the illustrated embodiment, the longitudinal member 125 extends forward beyond the apex of the angled members 121, 122. The hitch coupler 105 is coupled to a forward portion of the longitudinal member 125 that extends beyond the apex of the angled members 121, 122. In one or more embodiments, the hitch coupler 105 may be detachable from the longitudinal member 125 such that the appropriate type of hinge coupler may be coupled to the tongue 104 depending on the configuration of the hitch of the tow vehicle.
In the illustrated embodiment, the pair of stabilizing jacks 106, 107 are coupled to outer sides of the side rails of the frame 101. The stabilizing jacks 106, 107 are configured to stabilize the wheeled assembly 100 and the trailer when they are detached from the tow vehicle. In one or more embodiments, a lower end of each of the stabilizing jacks 106, 107 that is configured to engage the ground may include a flat plate 126 and/or one or more wheels 127. Additionally, in the illustrated embodiment, the stabilizing jacks 106, 107 are rotatable (arrow 128) relative to the frame 101. The stabilizing jacks 106, 107 are configured to rotate (arrow 128) between a deployed position (shown in
In the illustrated embodiment, the wheeled assembly 100 also includes a hitch receiver 129 coupled to the rear cross member 111 of the frame 101. The hitch receiver 129 is configured to enable attachment of another device besides the trailer to the wheeled assembly 100, such as, for example, a bike rack or a storage rack.
Additionally, in the illustrated embodiment, the wheeled assembly 100 also includes a storage compartment or container 130 coupled to the underside of the frame 101. In one or more embodiments, the storage compartment 130 is accessible from the floor inside of the trailer that is supported by the wheeled assembly 100.
