FIG. 3 , a perspective view of aportable restroom 10″ having yet another alternative design ofroof 18″ is illustrated, in accordance with an embodiment of the present invention. As in the previous embodiments,roof 18″ is connected to sidewalls 14 by fasteners, such as, screws, bolts or rivets or the like to facilitate quick and easy installation and removal.Roof 18″ includes acentral portion 48″ and aperimeter rim 50″ having radially and downwardly extendingflanges 52″ and 54″. In the present embodiment,central portion 48″ is substantially domed shaped. In an embodiment of the present invention,central portion 48″ is substantially hemispherical. Perimeter rim 50″ is configured as in the previous embodiments and mates withsidewalls 14. - Referring now to
FIG. 4 , a perspective view of aportable restroom 10′″ having yet another alternate design forroof 18′″ is illustrated, in accordance with an embodiment of the present invention. As in the previous embodiment,roof 18′″ is connected to sidewalls 14 by fasteners, such as, screws, bolts or rivets or the like to facilitate quick and easy installation and removal.Roof 18′″ includes acentral portion 48′″ which protrudes from asurface 80 ofroof 18′″.Central portion 48′″ is formed in the shape of half of a football.Roof 18′″ further includes aperimeter rim 50′″ having radially and downwardly extendingflanges 52′″ and 54′″. As in the previous embodiments, rim 50′″ is configured to close or seal againstsidewalls 14. - The present invention further contemplates a method for advertising goods and services using the embodiments of the portable restroom, as described above. The method includes attaching advertising indicia, for example, in the form of decals or thin sheets of plastic and/or paper having text and graphics disposed thereon to the sidewalls of the portable restroom. The
advertising sheets 70, as shown inFIGS. 2-4 , may be multiple sheets or one-piece sheets that wrap around thecylindrical sidewalls 14. Further, the method of the present invention also includes replacing the roof of the restroom with a roof that has a particular shape that coincides with an advertising scheme as presented onadvertising sheets 70. For example, if the advertising sheets are advertising a particular pop or soda product and manufacturer the roof of the portable restroom could take on the shape of the top of a pop or soda can. Similarly, if the advertising scheme, as presented onsheets 70, is directed to advertising a particular sports team, such as a football team, then the roof would be replaced with a roof that has a portion of the roof that resembles a football, such as the roof shown inFIG. 4 . Of course, the present invention contemplates other roof designs that would be used to complement other advertising schemes and objectives. Additionally, the present invention contemplates mounting or integrally forming other structures on the roof or other parts of the restroom to further complement the intended advertising scheme. - The foregoing disclosure is the best mode devised by the inventors for practicing this invention. It is apparent, however, that methods incorporating modifications and variations will be obvious to one skilled in the art of portable restrooms thereof. Inasmuch as the foregoing disclosure is intended to enable one skilled in the pertinent art to practice the instant invention, it should not be construed to be limited thereby but should be construed to include such aforementioned obvious variations and be limited only by the spirit and scope of the following claims.
