Description:
RELATED APPLICATIONS 
       [0001]    This application is a continuation-in-part of U.S. patent application Ser. No. 12/250,967, filed Oct. 14, 2008, the entirety of which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to prefabricated, multi-sided building and construction system. In particular it relates to a prefabricated gazebo and a construction system which utilizes lightweight framing components, a unique roof support and roof which results in the construction of the gazebo. The gazebo includes an optional screen enclosure kit, an optional solid panel kit and an optional storm window kit. 
       BACKGROUND OF THE INVENTION 
       [0003]    Multi-sided buildings are known in the prior art. One group of these buildings generally “round” and has a substantially circular outer wall or side made from a plurality of generally flat walls. One type of the building in this group is a gazebo. The majority of gazebos have six to eight sides and thus have six to eight outer walls. In addition, most gazeboes have a single roof. Gazebos are predominately found in a areas of multi-family homes, single family homes or public parks. Gazebos are predominately used during the warm weather in the Northeast, Midwest and Northeast portions of the U.S. However, in the Southeast and Southwest they are used during the entire year. Since most gazebos are only used during the warm weather they do not include windows and/or doors. Therefore they are not provided with screens to keep insects and other undesirable life outside of the confines of the gazebo. 
         [0004]    Most gazebos are made from wood and constructed at a location separate from the location where they are to be used. They are normally made at a factory and delivered fully assembled to a buyer&#39;s residence. Since most gazebos used around homes are about 10 to 15 feet in diameter, the delivery of these involves a considerable expense and transportation problems. Only the very large gazebos, such as those which house a band in a park, are constructed on site. The wood construction of the gazebos also requires yearly maintenance and painting. 
       DESCRIPTION OF THE PRIOR ART 
       [0005]    U.S. Pat. No. 4,173,855 discloses a prefabricated building or gazebo having an octagonal configuration. The structure includes a structural support system, a floor system carried by the support system above the level of the ground, and a roof system supported solely by the support system. The floor and roof systems are provided with collars, each with at least three sides, which are spaced apart and are located on the central vertical axis of the structure. The structural support system includes at least three vertical support columns with each column being spaced an equal distance from the central axis of the structure and also equal distances form adjacent columns. The roof system includes rafters of equal length one for each side of the roof collar and corresponding support column. However, this structure does not offer an easily assembled gazebo constructed of light weight materials, such as plastic and which can be readily assembled by a single individual. It also does not offer a basic gazebo structure with different embodiments. 
         [0006]    U.S. Pat. No. 3,908,329 discloses a polygonal building which has a perimeter wall made from a plurality of initially roughly plumbed rectangular wall sections arranged in end-to-end but spaced apart relation to each other. Roof rafter extend from a common point, approximately centrally of the building, down to and between the upper ends of adjacent wall sections. A perimeter cable is threaded through the all of the wall sections and the roof rafters. Tightening of the cable plumbs the wall sections and centers the roof rafters. While this is a multi-sided building, there is no disclosure of it being used and a gazebo, being constructed from plastic or other non-metallic materials. Further, the roof of this building utilizes sheathing and conventional shingles. However, there is no disclosure of the use of preformed roof panels. 
         [0007]    U.S. Pat. No. 6,349,511 discloses a gazebo which is fabricated from lightweight aluminum framing components. The preferred structure has eight sides. Each side includes a pair of vertical posts, a pair of header members, a rail and foot member, columns disposed between the rail and foot member and the pair of header members, and an insulated composite roof panel. As each side unit is attached by self mating beam and vertical post members to an adjacent side unit, the gazebo structure is formed. The gazebo can be provided with screening on the vertical posts and shingles on the roof. While this gazebo is made from eight (8) preformed single side units, each side unit required a considerable amount of space on a delivery truck. However, there is no disclosure of constructing a gazebo from a plurality of light weight materials, such as plastic and which can be readily assembled by a single individual. 
         [0008]    Therefore, what is lacking in the art is a gazebo structure which can be constructed from a plurality of light weight materials, such as plastic and which can be readily assembled by a single individual. The unassembled lightweight materials can be packaged in a relatively compact container for shipping purposes. Therefore, the individual light weight materials can shipped to a user&#39;s residence in a very compact container without the use of specialized trucks or delivery vehicles. The art also lacks a gazebo that can be enclosed with screens to keep out insects and other unwanted life. Further, the art does not provide gazebos with kits and or other means to provide solid enclosures for the gazebos. 
       SUMMARY OF THE INVENTION 
       [0009]    The present invention includes a system or kit of injection molded panels and other components having integrated connectors which combine together to form an enclosure, preferably in the form of a gazebo. Optional kits are available to provide the gazebo with screen and/or solid enclosures. The support posts, roof rafters, roof supports are formed of extruded plastic. The roof panels and walls are formed of injection molded plastic to interlock with one another without the need for separate I-beam connectors. The system incorporates a minimum number of components to construct a gazebo type enclosure by integrally forming connectors into the extruded components and panels. This minimizes the need for separate extruded or molded connectors to assemble the enclosure. The symmetry of the support posts, roof rafters, roof supports, roof panels and other components also minimizes the shapes of the injection molded connectors and panels and simplifies construction of the gazebo. The heavy duty interlocking construction of the support posts, roof rafters, roof supports, roof panels and other components create a structural frame which permits construction of larger gazebos. The support posts are extruded which allows them to be formed to a sufficient length to provide a gazebo with adequate height for all intended purposes, including the provision of overhead fans. This eliminates the need for a plurality of support posts to be stacked one above the other to achieve the heights desired. Injection molding allows the roof panels to be formed with integral cross-bracing, ribs and gussets for increased rigidity when compared to blow molded or extruded panels. 
         [0010]    In one embodiment, the gazebo system or kit utilizes interlocking support posts, roof rafters and roof supports to create a structural frame. Three types of support structure construction are integrated into the structural frame. The first is utilized for the support posts, the second is utilized for the roof rafters and the third is utilized for the roof supports. The support posts are constructed to cooperate, via integrally formed connectors, with the roof rafters and other members that permit the support posts to be secured to a base or other means to secure the support posts to the ground. The roof rafters are constructed to cooperate, via integrally formed connectors, with the roof supports to form a support structure which will support the roof panels. The roof supports also include integrally formed connectors which permit the roof supports to cooperate with the roof rafters to form a support structure which will support the roof panels. The structural frame may include provisions for standard electrical current hookups. The roof support may also include connectors to permit the use of additional components such as fans or lighting components. 
         [0011]    Accordingly, it is an objective of the instant invention to provide a system or kit which utilizes plastic frame and panel members having integral connectors to create a gazebo type structure or enclosure of varying dimensions using common components. 
         [0012]    It is a further objective of the instant invention to provide a system or kit wherein the structural components include integrated connectors which accommodate injection molding plastic formation of the components for increased structural integrity. 
         [0013]    It is yet another objective of the instant invention system or kit which utilizes roof rafters and roof supports having interlocking bosses and apertures to increase rigidity and prevent bowing of the rafters and supports. 
         [0014]    It is a still further objective of the invention to provide structural roof panel members including integrated connectors, cross-bracing and gussets to increase rigidity and prevent bowing of the roof panels. 
         [0015]    It is still yet another objective of the instant invention to provide a system or kit which reduces the number of components required to assemble a gazebo and simplifies construction of a gazebo.

       [0092]    While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated. 
         [0093]      FIG. 1  illustrates a perspective view of a gazebo type structure, generally referenced as  10 , constructed in accordance with a preferred embodiment of the present invention. In the preferred embodiment, the components of the gazebo, including the roof, are preferably formed of polyvinylchloride (PVC) or other suitable plastics such as polystyrene, polypropylene or polyethylene, through the process of injection molding or extrusion. The gazebo is set upon a base or platform  12 . The base or platform may be included as an element of the gazebo, but preferably it is not. The base can be formed as a poured concrete slab or platform, as a wooden deck, or as a plurality of interconnected components such as bricks or pavers. One of the requirements of the base or platform  12  is that it is capable of properly supporting and securing the support posts  14  and attached gazebo structure, including the roof assembly  22 . The base or platform must also be capable of providing proper support for individuals and other objects enclosed within the gazebo. 
         [0094]    Referring to  FIGS. 2A-C  the support posts  14  are secured to the base  12  utilizing attachment posts  16 . These attachment posts are preferable made from steel. However, other materials could be used providing these materials permit the support posts  14  to be properly secured to base  12 . The base of the attachment posts are provided with apertures  18 , as shown in  FIGS. 2B and 2C . The attachment posts  16  are preferably secured to the base in the manner illustrated in  FIG. 2C . A plurality of fasteners  20  are secured in base  12 . The posts are secured to the fasteners using nuts and washers. The fasteners  20  could be set into a poured concrete slab prior to its drying. They could also be set into holes drilled into a dried and cured concrete slab and secured with expansion anchors. When a wooden deck is employed as the base, the fasteners  20  can be bolts or screws. Depending on the type of base that is used, appropriate fasteners are utilized.  FIG. 2A  illustrates that a number of support posts, in this case  8 , are secured to base  12 . The support posts  14  are preferably secured in a substantially circular pattern. 
         [0095]    The support posts  14  are next secured to the attachment posts  16  by use of fasteners. Preferably a support post  14  is placed over an attachment post  16  and set onto base  12 . After the support post  14  is in place it is secured to the attachment post  16  with fasteners. The fasteners are inserted into apertures which are drilled into posts  14  and  16 . 
         [0096]    A roof for the disclosed embodiment of the gazebo includes an upper roof and a lower roof. While a multi-layered is disclosed, a roof comprising a single layer is an alternative. The roof  22  comprises a plurality of roof support members and roof panels. These roof support members and roof panels are readily assembled from a plurality of various components as will be described hereinafter.  FIGS. 4-6  illustrate an assembly of one of the roof support members  23 . A roof support member  23  is formed from roof rafters and roof supports. A lower roof rafter  24  is positioned below and aligned with an upper roof rafter  26 . Roof rafters  24  and  26  are secured together, at one end thereof, by an inner roof support  28 . A receptacle or socket  30  is attached to one end of rafter  24 , as illustrated in  FIG. 5 . Receptacle  30  is provided with a connection member  32  along one side.
