The present invention relates generally to modular containers used for transport and/or storage of goods, and specifically to a utility trailer system incorporating the same and a method of transporting the same.
There are devices that allow for the storage and transportation of various bulky items and the like. Utility trailers, for example, are typically coupled to trucks, cars or other vehicles and are used to transport various types of goods including automobiles, motorcycles, furniture, household goods and other items. Some utility trailers have protective enclosures, and can include a trailer bed having an undercarriage, axles and wheels attached thereto. A hitch, for connecting the trailer to a towing vehicle, is often times attached to the front of the trailer bed chassis. The protective enclosure is typically a box-like structure covering the trailer bed and secured to the chassis, which would include doors which permit access to the interior of the enclosure.
As an alternative to utility trailers, users may utilize rental trucks having permanently attached enclosures to transport items from location to location. There are, however, drawbacks in using utility trailers and rental trucks as previously described. In many instances, such utility trailers and trucks do not facilitate the extended storage of goods (rather, they facilitate the transportation of goods) and are bulky to situate in close proximity to, for example, a house or construction site. If a person desires to store goods for an extended period of time, such a person generally transports the person's goods to a storage facility and perhaps uses a utility trailer or rental truck to transport such goods.
There are stand-alone storage containers, however, that can be rented for a period of time (e.g., week, month). Such storage containers are handled and transported through special carrier frames systems, which are complex to operate. A person handling such a carrier frame would be in need of specialized training. Thus, the renter of such a stand-alone storage container would not be capable of operating such a carrier frame system without specialized training. Instead, a operator with specialized training is needed to handle and transport (usually in conjunction with a vehicle) such a stand-alone container. Generally, the entity supplying a stand-alone container would employ such an operator to handle and transport the rented container. Thus, one drawback is that a user is constrained by time and availability limitations of the operators employed by the entity supplying the storage containers as well as that of the carrier frame systems.
Another drawback is that normally such stand-alone containers are composed of a solid structure that takes up a significant amount of space. If such containers are no longer needed to store items, the containers cannot be easily dissembled. Instead the containers need to be both handled and removed by a specialty operator. Otherwise, the containers are not utilized and take up space. In addition, prior methods only contemplate the handling/transportation of one container per carrier frame system. For multiple containers, the carrier frame system and operator would have to repeat the process of securing the container at the original site, transporting the container to the new site, and returning the system to the original site for each container.
Accordingly, there is a need to have an improved containment system capable of storing goods that is easily transportable by the user at the discretion of the user as can be easily handled by such user.
The present invention advantageously provides a method and system for providing a modular container for a utility trailer comprising a bottom panel assembly; an upper panel assembly stackable on the bottom panel assembly, the upper panel assembly and the bottom panel assembly defining a cavity therein when the modular container is in a disassembled state; a plurality of panels being substantially containable within the cavity and being removably securable to the bottom panel assembly and the upper panel assembly when the modular container is in an assembled state to define a substantially enclosed volume; and the bottom panel assembly defining a pair of slots sized to engage a portion of the utility trailer and a pair of apertures larger than the pair of slots sized to engage a portion of a fork lift.

As will be explained in greater detail below, the jack support 16 can be extended using the support member 20 (preferably when the upper frame 32 is tilted in relation to the base frame 12 because the jack support 16 can provide extra support for the trailer frame 10). The support member 20 can otherwise partially retract within the sleeve 18 such that the base 22 does not engage the ground, which is important when the trailer frame 10 with or without container 50 is moving or being towed by a vehicle.
Referring back to the base frame 12, the rear end 46 of the base frame 12 is pivotally connected at pivot point 30 to an upper frame 32 along the intermediate length of upper frame 32. The upper frame 32 is comprised of longitudinal extending members interconnected through generally horizontal bisecting members, the interconnected upper frame members forming a substantially rectangular arrangement having a forward end 35 and a rear end 33. It is understood, however, that the upper frame 32 can be comprised of other structural members as desired or required to support a load thereon. Optionally, an upper frame support surface can be secured to the interconnected upper frame members to provide added support for items loaded onto the upper frame 32.
The upper frame 32 incorporates a pair of spaced axles 36 having dual wheels 38 on both ends of the axles 36. A suspension assembly (not shown) is capable of operably supporting and connecting the axles 36 such that the dual wheels 38 are provided on both sides of the upper frame 32. The upper frame 32 can also incorporate a winch assembly 24. The winch assembly 24 comprises a winch wire 28 that can be wound around a winch drum 26, the winch wire 28 capable of extending in length past the length of the upper frame 32 and being secured to a container 50 or the like. The winch assembly 24 can be powered using an electrical source from an associated vehicle or through a separate power source. Alternatively, the winch assembly can be operated manually.
The upper frame 32 also incorporates slidably moving means to move the container 50, the slidably moving means comprising, in a preferred embodiment as illustrated in
A hydraulic assembly 40 as shown is

The container 50 is comprised of two side walls 60, a front wall 62 having a securing device 63 to secure the winch wire 28, a rear wall 66, a roof 64 and a floor 68. The rear wall 66 may be comprised of a door, a plurality of doors, sealable apertures or the like. In the preferred embodiment, the container 50 of present invention is substantially formed as a single piece in order to minimize the occurrence of breaches in the protective covering afforded by the container 50. It is within the scope of the present invention, however, to include a container 50 that is constructed in a modular fashion that may include individually formed walls 60, 62, 66, roof 64, floor 68 or a combination thereof and that are joined together through a variety of methods including but not limited to welding. The container 50 can be constructed of material that protects the contents of the trailer, such as fiberglass, aluminum, metal, composites or other suitable materials. The shape of the container 50 can be any shape suitable for enclosing and protecting its contents. Furthermore, the container 50 may incorporate a variety of devices to facilitate movement of the storage unit including, but not limited to, skids, castors, steel bearing wheels, omni wheels, or other suitable devices. Preferably, castors 52 are located on the underside of the container 50, secured to the exposed exterior portion of the floor 68. It is preferred that four casters 52 are positioned generally around the four corners of the floor 68 such that the pair of castors 52 running along the length of the container are in line with one of the channels 6.
The container 50 allows for storage of items when the container is either loaded onto the trailer frame 10 or when the container unit is not loaded onto and separate from the trailer frame 10 as a stand-alone unit. Furthermore, the trailer frame 10 and container 50 of the present invention affords the user the convenience of placing items within the storage unit at the user's leisure as well as transporting the storage unit at the user's leisure, since the present invention allows for a user to releasably attach the utility trailer to a vehicle for towing. Accordingly, the user does not have to drive or hire a third party to drive bulky storage trucks or the like and may, instead, utilize the user's private vehicle or a similar type of vehicle. Additionally, the user does not have to rely on a storage container moving services, which are many times unreliable and are limited in their availability.

The roof panel assembly 110 is connected to the floor panel assembly 120 by a plurality of vertical posts 130-131. More specifically, the tope ends of the posts 130-131 are removably secured to the roof panel assembly 110 while the bottom ends of the posts 130-131 are removably secured to the floor panel assembly 120. Preferably there are four corner posts 130 removably connected at the corners of the roof and floor panel assemblies 110, 120. Two center posts 131 are removably connected at the mid-point length of the roof and floor panel assemblies 110, 120. Of course, any number and positioning of posts can be used. Together, the roof panel assembly 110, the floor panel assembly 120 and the posts 130-131 form the framework structure for the container 100. Optionally, rub rails (not visible) can be connected to the posts 130-131 in a horizontal arrangement along the length of the container's interior volume.
A plurality of wall panels 140 are removably secured to the framework 110, 120, 130-131 to provide housing and protection (e.g., protection from external elements such as wind, rain and sun) for contents within the container 100. The panels can be removably secured to the vertical posts 130-131 via bolts or other means. Similarly, a roof panel 111 and a floor panel 121 (
The vertical members can be constructed of any suitable materials including but not limited to steel, aluminum, any other metal or composites thereof, plastic, wood or any other suitable material. Preferably the panels are made from a lightweight, flexible materials including but not limited to fiberglass, aluminum, plastic and the like.
The container 100 also comprises two doors 160 having hinges 161. The hinges 161 are removably secured to the rear corner posts 130 to form the back wall of the container 100. The hinges facilitate pivotal connection between the doors and the posts 130 for opening and closing.
Preferably, all bolt holes are pre-drilled in the posts 130-131, panel assemblies 110, 120, panels 140 and other components of the container 100 to facilitate ease of assembly.

The perimeter beams 112-115 form a ridge surrounding and extending downward from the bottom surface of the roof panel 111. Importantly, the roof joists 116 have a height that is less than the height of the perimeter beams 112-115. As will be described below, this is important for shipping the container 100 as a kit. If desired, the perimeter beams 112-115 can have a flange at their edges or other structural and functional details such as slots, C-channels, holes, etc for facilitating removable connections or stacking.

The perimeter beams 122-125 form a ridge surrounding and extending upward from the top surface of the floor panel 121. Importantly, the floor joists (not visible) have a height that is less than the height of the perimeter beams 122-125. As will be described below, this is important for shipping the container 100 as a kit. If desired, the perimeter beams 122-125 can have a flange at their edges or other structural and functional details such as slots, C-channels, holes, etc for facilitating removable connections o stacking.
It is preferred that the modular container 100 may be delivered as a kit, which may be transported in conjunction with the trailer described above.

The cavity 190 is sufficiently large enough to accommodate all of the remaining components of the container 100, including the posts 130-13, doors 160, panels 140, casters 150, and all necessary hardware (generically illustrated as a box). Thus, the entirety of the remaining components of the container 100 are located within the spaced formed by the housing formed by the floor and roof panel assemblies 110, 120. In other words, the panels and posts are sandwiched between the stacked floor and roof panel assemblies 110, 120 such that the total height of the entire kit does not exceed 10 inches. The modular container in this preferred embodiment can be assembled in less than two hours by two technicians.
Approximately 19-21 modular container kits 100 can be delivered on a conventional tractor trailer bed (3 stacks of approximately 7 modular container kits each). As stated above, the container kits are devised of vertical members, support posts and “panels.” The upper and bottom panels all come to be aligned and assembled using support posts. The composite panel inserts slip into place to completely enclose the unit. In such an embodiment, the modular container is assembled quickly using bolts and screws. This simplified design saves time and product weight. (Which addresses problem typical of prior art containers, which are assembled using six panels—top, bottom, side walls, door(s) and end wall. The modular container according to the preferred embodiment of the present invention, however, utilizes only two complete panels and upright supporting posts.)
Multiple bottom and upper panels can be stacked on top of each other to minimize container space when more than one modular container is being utilized. Vertical members can also be stored adjacent to or within the stacked upper and bottom panels. Panels can likewise be contained within or placed on top of the stacked bottom and upper panels.
Such ease of storage allows a user to store and utilize multiple modular containers when desired, as well as facilitates the ease by which a user can move/transport goods. For example, when a user has a need to move a substantial amount of goods, such user is capable of assembling the desired number of modular containers and storing the user's goods in the modular containers. Then, using the trailer assembly of the present invention, the user can transport each modular container to a desired site until all the modular containers have been moved to such site. The user can then remove all the goods from the modular containers. At this point, however, the user need not move each empty modular container back to the original site. Instead, the user can disassemble the modular containers, stack the parts thereof, and transport more than one, substantially all, or all of the modular containers back to the original site, thus, saving valuable time and effort.
