CROSS-REFERENCE TO RELATED APPLICATIONS

This is a reissue application of U.S. application Ser. No. 15/497,684, filed on Apr. 26, 2017, now U.S. Pat. No. 10,723,547, issued on Jul. 28, 2020, the entire disclosure of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention is in the field of cargo container attachments, particularly, attachment adapters.

2. Description of Related Art

In recent years, usage of cargo containers, often called cargotainers, for construction of home, businesses, and offices has increased. This may be due to a number of reasons: relatively low cost compared to traditionally available options, availability of shipping containers, and overall value. In an effort to make repurposing of a cargo container more economical, owners may opt to do refurbishing work themselves. However, due to the corrugated nature of the surfaces of cargo containers, adding a vent or other attachments may require more skill, more time, and more equipment than the owners may possess. Hiring a professional to do refurbishing may be the only option for many people, which may be costly.

Additionally, presently existing solutions for a typical person may only be a stopgap, and may not be long-lasting, as the solutions may be prone to environmental deterioration, such as rust, or simply may not be attached securely enough, to be used as a permanent solution. Therefore, what is clearly needed is a relatively easy, and long-lasting way for an average person to add attachments to cargo container.

DETAILED DESCRIPTION OF THE INVENTION

What is generally provided in embodiments of the present invention is an adapter shaped substantially to the corrugated sides or roof of a shipping container, to allow a person to easily add attachments while maintaining a weatherproof seal.

FIGS. 1a to 1c are views of various angles of a cargo container adapter 100 according to one embodiment of the present invention. Cargo container adapter 100 comprises a base 102, connected with an intermediary section 104 through a sidewall configuration 105, and a collar 106 connected with the intermediate section 104 through a top surface 108. The base 102 includes upper and

lower corrugation portions

110, 112 to connect with corrugated panels of a cargo container. Adapter 100 may be constructed with a flexible and durable material, such as fiberglass-reinforced plastic (FRP), so that adapter 100 may conform its shape slightly to fit on imperfect cargo containers. The material may also possess a high degree of UV-resistance so that adapter 100 may be less susceptible to sun damage after being installed. Base 102 is shaped to substantially fit onto the ridges and grooves of the corrugated roof of a cargo container. In other embodiments, the base 102 may be formed to fit on other surfaces with ridges and grooves of different shapes and sizes, such as the side panels, the rear panel, or the door of a cargo container. Base 102 may also be constructed with different sizes, bigger or smaller, depending on the attachment a user seeks to install.

Intermediary section

104, which is positioned between base 102 and collar 106, acts as sort of a funnel. While base 102 sits flat on a surface of the cargo container to create a seal around the perimeter of adapter 100, intermediary section 104 may be hollow. The size of intermediary section 104 in this embodiment is substantially larger than the diameter of collar 106, thus allowing one to cut an opening with a diameter larger than the diameter of collar 106. This may allow more surface area for air to disperse as it enters, or gather as it exits. The size difference between intermediary section 104 and collar 106 also allows for more flexibility in installing adapter 100, since the extra space may allow the user to be more lenient towards size and positioning of cutting an opening. In other embodiments, the size and shape of the intermediary portion may be any shape or size, depending on the needs and requirements of the user.

Collar

106 in this example protrudes from intermediary section 104 at a distance to allow enough area to fasten a venting device to the collar. In this embodiment, collar 106 has a diameter sized to fit a standard 12″ whirlybird wind turbine, or a powered ventilation device. In other embodiments, the collar may be adapted for various shapes and sizes to fit other devices, for example, and without limitation, the collar may take a square shape, or the collar may protrude more or less. In other embodiments, still, the collar may not be present at all. This may be useful in a case, for example, where a user seeks to install a skylight or a window.

FIG. 2 is an isometric view of a cargo container adapter 200 according to another embodiment of the present invention. Adapter 200 may be identical to cargo adapter 100, except adapter 200 may have a mesh screen 202 installed, and pre-drilled holes 204[1 . . . n] (henceforth referred to collectively as holes 204). Mesh screen 202 is a removable attachment which may help prevent debris or other particles from entering through the vent. In other embodiments, the mesh screen may be replaced with other types and sizes of mesh screens, for example one with finer openings, or even an air filter.

Holes

204 may be pre-drilled to fit standard screws, or other fastening means. A user may additionally use holes 204 as a guide to mark or drill holes onto surfaces of a cargo container. The use of fasteners may be best suited when adapter 200 is intended to be mounted vertically, such on a wall or door, or when adhesive may not be secure enough.

It should be understood that the features shown in the above embodiments are not required to be present together, and other embodiments may possess any combination of features found in the above example embodiments without deviating from the inventive concept of the present invention.

FIG. 3 is an isometric view of a sealing gasket 300 according to one embodiment of the present invention that may be used with adapter 100. Gasket 300 in this embodiment is shaped substantially like the shape of base 102, and is designed to form a weatherproof seal. Gasket 300 may be constructed with any material commonly used for creating weatherproof seals, such as rubber or nylon. In other embodiments, other sealants, such as silicone or caulk, may be used in place of a gasket. Besides acting as a weatherproof seal, gasket 300 may have strong adhesive readily applied with a protective cover to be removed at time of use: a top surface adhesive layer 302, and a bottom surface adhesive layer 304. This may allow a user to install adapter 100 without screws. However, for heavier attachments, especially when installed vertically, the use of only adhesive may not be an option, and it may be advisable use screws or other fasteners in additional to the adhesive.

FIG. 4 is an exploded view showing an assembly order 400 according to one embodiment of the present invention. Assembly order 400 comprises a cargo container roof 402 (a segment of which is illustrated here) with a hole already cut out by a user, a sealing gasket 300, and a cargo container adapter 100. Sealing gasket 300, with adhesive top surface 302 and adhesive bottom surface 304, makes direct contact with and adheres to roof 402. Adapter 100 is placed directly on top of and also adheres to gasket 300, ensuring adapter 100 is as centered on top of gasket 300 as possible to ensure that a weatherproof seal is established around the perimeter of adapter 100.

FIG. 5 is an isometric view of an adapter 100 installed on a roof of a cargo container 502 (a portion is shown in FIG. 5 in dotted line) according to one embodiment of the present invention. As apparent by FIG. 5 , the ridges and grooves on the roof of cargo container 502 occur in regular intervals. Adapter 100 may be placed at various places, and, due to the regularity of the ridges and dips, adapter 100 may fit and sit flat against the surface on many areas on the roof of cargo container 502. In the event that the cargo container has become misshapen or deformed, adapter 100 may not fit in certain areas, and it may be advisable to test out other areas to find an area in which adapter 100 fits the best in order to maintain a weatherproof seal around the perimeter of adapter 100.

FIG. 6 is a flow chart 600 for steps of a method for installing an adapter onto a cargo container according to one embodiment of the present invention. The steps of method 600 takes place after a user has identified an area in which he or she would like to install the adapter, and has done any pre-install steps, such as cleanup, in the area. At step 602, the user places the adapter onto the surface in the area they would like to install the adapter. At this point, the user may mark the outer boundary of the adapter on the area while using the adapter as a guide. At step 604, the user moves the adapter aside, and proceeds to cut a hole that is within the previously marked boundary, with enough space to spare between the outer edge of the cut hole, and the inner edge of the marked boundary for the base of the adapter to sit. At step 606, if the user has opted to use a gasket for sealing, step 608 is reached. At step 608, the user removes a bottom adhesive cover on the bottom of the gasket. At step 610, the user lines up the gasket, now with the bottom adhesive exposed, with the inner edges of the marked boundary and applies firm pressure to ensure a seal is formed all the way around. At step 612, a top adhesive cover is removed from the top of the gasket. Returning to step 606, if the user opts to use another type of sealant, step 614 is reached. At step 614, the user may apply the sealant evenly, and with sufficient quantity around the inner edges of the marked boundary to form a weatherproof seal.

At step 616, after the gasket has been installed or the sealant has been applied, the adapter is placed within the marked boundary, and on top of the gasket or sealant, ensuring the base of the adapter makes substantial contact with the gasket or sealant. At step 618, the adapter is fastened to the surface by applying firm pressure around the perimeters of the base of the adapter to ensure a good seal with the adhesive of the gasket, or with the use of screws or other types of fasteners. After this point, the user is free is install their attachment.

It will be apparent to one with skill in the art, that the embodiments described above are specific examples of a single broader invention which may have greater scope than any of the singular descriptions taught. There may be many alterations made in the descriptions without departing from the spirit and scope of the present invention.
