PRIORITY  
       [0001]    The present application claims priority Under 35 USC 119 filed on Aug. 1, 2005. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to porches, and more particularly pertains to a portable and folding porch for use on motor homes, travel trailers and mobile homes. 
         [0004]    2. Description of the Prior Art 
         [0005]    Various types of porches are known in the prior art. A typical example of such a retractable porch for mobile homes is to be found in U.S. Pat. No. 2,760,238, which issued to F. Lane on Aug. 28, 1956. This patent discloses a vestibule construction for use with a trailer having a side door. The vestibule includes a platform having vertically extending legs and a horizontal support surface. The vestibule is designed with a knock down construction. U.S. Pat. No. 2,828,842, which issued to G. Plumley et al on Apr. 1, 1958, discloses a cabana for attachment along a side width wall of a travel trailer. U.S. Pat. No. 2,883,712, which issued to C. Shelamer on Apr. 28, 1959, discloses a knock down trailer porch having screened in side portions and a roof formed by a retractable awning. U.S. Pat. No. 3,348,345, which issued to L. Byers et al on Oct. 24, 1967, discloses a rotatable porch for a mobile home which is secured by frame rail members attached on an underside of the vehicle. U.S. Pat. No. 3,808,757, which issued to G. Greenwood on May 7, 1974, discloses a knock down porch construction which includes a porch frame having vertically extending perpendicular first and second side railings. Adjustably extensible legs are secured on an underside of the porch frame. U.S. Pat. No. 4,413,855, which issued to F. Flanagan on Nov. 8, 1983, discloses a sliding patio for travel trailers and mobile homes. A pair of spaced parallel frame members having facing channels forming a horizontal guide track and are secured to the frame on an underside of the vehicle. A patio is received for sliding movement between extended and retracted positions in the guide track. The patio is provided with collapsible side railings and downwardly extending retractable wheeled support legs. 
         [0006]    The average hand built deck requires days or even weeks to construct. Furthermore, decks which are built from wood require yearly treatment in order to prevent these decks from rotting. Furthermore, these wooden decks require painting every few years to maintain attractiveness. 
         [0007]    While the above mentioned devices are suited for their intended usage, none of these devices disclose a portable and folding porch for motor homes, travel trailers and mobile homes. Inasmuch as the art is relatively crowded with respect to these various types of porches, it can be appreciated that there is a continuing need for and interest in improvements to such porches, and in this respect, the present invention addresses this need and interest. 
       SUMMARY OF THE INVENTION 
       [0008]    It is an object of the invention to provide a portable, folding covered porch that can be attached to any dwelling to create a temporary or permanent exterior structure that can be removed, transported and stored in the folded position. After which, the porch can be unfolded and attached to the same or another dwelling. 
         [0009]    It is an object of the present invention to provide not only a platform but also shelter from adverse weather conditions. 
         [0010]    It is another object of the present invention to match or surpass the expedience demonstrated by homeowners, whether the dwelling is manufactured or built on-site. 
         [0011]    It is another object of the present invention to provide a durable, reliable exterior structure that is weather resistant, flame resistant, pest resistant and low maintenance. 
         [0012]    It is another object of the present invention to provide an adjustable leg points in order to accommodate different terrains. 
         [0013]    The present invention provides sufficient flexibility to allow movement from each dwelling. 
         [0014]    The present invention provides affordable and practical housing options. 
         [0015]    In view of the foregoing disadvantages inherent in the known types of porches now present in the prior art, the present invention provides an improved retractable porch for mobile homes. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved portable and folding porch for mobile homes which has all the advantages of the prior art porches and none of the disadvantages. 
         [0016]    The present invention provides a portable folding porch to accommodate homeowners searching for a more feasible and practical approach to home design, utility and improvement. The portable and folding porch of the present invention is cost-effective durable and convenient. 
         [0017]    The porch of the present invention is resilient, light weight and very low maintenance. The porch of the present invention does not require treatment for painting and is flame, pest and weather resistant. The porch of the present invention is extremely versatile. The porch can be closed before severe storms such as hurricanes and tornadoes to provide an additional safety barrier. The porch of the present invention does not require detachment while the houses in transit as long as the porch is folded and secured. The porch of the present invention can include roll down screens for pest control. 
         [0018]    The present invention includes an outer side rail assembly, an inner side rail assembly, a main support pole, a platform assembly and a cover assembly. 
         [0019]    Some of these are movable assemblies and are fastened with hinges, and the side rail assemblies are secured with spring bolts when the porch is deployed. The platform assembly includes legs having leg extensions for height adjustment. Each leg extension has a rubber end for concrete and may be reversed for a blunt for ground mounting. Once the legs are extended, a three-piece skirt is unfolded to surround the legs and cover the space between the platform and ground. 
         [0020]    The portability of the present invention provides expedient transportation and circumvents the assembly cost of conventional decking. 
         [0021]    It is therefore an object of the present invention to provide a new and improved portable porch for mobile homes which has all the advantages of the prior art porches and none of the disadvantages. 
         [0022]    It is another object of the present invention to provide a new and improved portable porch for mobile homes which may be easily and efficiently manufactured and marketed. 
         [0023]    It is a further object of the present invention to provide a new and improved portable porch for mobile homes which is of a durable and reliable construction. 
         [0024]    An even further object of the present invention is to provide a new and improved portable porch for mobile homes which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such porches economically available to the buying public. 
         [0025]    Still yet another object of the present invention is to provide a new and improved portable porch for mobile homes which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith. 
         [0026]    Still another object of the present invention is to provide a new and improved portable porch for mobile homes, motor homes and travel trailers which may easily be retrofitted to existing vehicles. 
         [0027]    Yet another object of the present invention is to provide a new and improved portable porch for mobile homes, motor homes and travel trailers which may easily be transported in a collapsed condition when not in use.
