Description:
FIELD OF THE INVENTION  
       [0001]     This invention relates to prefabricated windows for installation in plastic utility sheds or buildings.  
       BACKGROUND OF THE INVENTION  
       [0002]     In the traditional building industry, the use of prefabricated components is conventional and increasing in diversity. New materials are also being introduced, at a rapid pace, into buildings. The use of large molded plastic components has given rise to modular buildings which can be purchased as a kit and assembled from the preformed parts. Such buildings can be used for many purposes. For example, out buildings, such as tool sheds, storage sheds, garages, animal shelters, and other enclosures may be completely assembled from molded components. The panels for the buildings may be molded in relief to have exterior simulated natural finishes, such as brick and mortar, stone, weatherboard, etc. In building panels with one ply, the interior molded finish may have a contour that is the reverse of the exterior.  
         [0003]     Typically, these modular buildings are molded with all the necessary pieces in a particular location, including the windows and doors, according to the design of the mold. However, because the sheds may be put to so many different uses and situated in so many places, the specific layout of the prefabricated window openings may not be the optimum for the location or the use of the building.  
         [0004]     For instance, utility sheds are well accepted for use in storage of lawn and garden equipment, as well as general all-around home storage space. Typically, items such as garden tractors, snow blowers, tillers, ATVs, motorcycles and the like consume a great deal of the garage floor space available, forcing the homeowner to park his automobile outside. A utility shed may employ a number of different panel systems, or kits, comprising blow molded or extruded panels and connector members for forming a wide variety of smaller sized storage structures. If a utility shed is mass produced, it is not practical to form intricate shapes and/or sharp corners required for integrated connectors necessary for a window. In addition, blow molded plastic components are hollow and cannot be formed with the integral strengthening ribs and gussets possible with injection molding. In this example, the owner may wish to place a window where it does not interfere with the storage items, or on a wall where natural light would be most beneficial.  
         [0005]     What is needed in the art is a modular window that may be incorporated in the building after the optimum location or locations is/are determined.  
       SUMMARY OF THE PRESENT INVENTION  
       [0006]     Disclosed is a window kit for use in a pre-fabricated plastic utility shed. The kit includes a one piece outside frame, a one piece inside frame and a panel spanning the frames. The inside frame and the outside frame have cooperating fasteners to secure the frames together with the panel and the edges of the building opening between them. The panel has complementary apertures to the cooperating fasteners to secure the panel in the frames. The window of the instant invention incorporates a minimum number of components to construct a rigid enclosure that increases the strength of the wall, thus simplifying assembling the enclosure. The interlocking construction of the window creates a structural reinforcement for securement to larger sidewalls without loss of strength.  
         [0007]     Therefore, it is an objective of this invention to provide a modular window kit for covering an opening formed in a structure.  
         [0008]     It is another objective of this invention to provide an open interior frame for trimming out an opening formed in a structure.  
         [0009]     It is a further objective of this invention to provide an open exterior frame for trimming out an opening formed in a structure.  
         [0010]     It is still another objective of the invention to provide a transparent panel spanning the opening of the interior and exterior frames.  
         [0011]     It is yet another objective of this invention to provide cooperating elements on the interior frame, the exterior frame and the transparent panel to secure the components together in the structure.  
         [0012]     Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of the specification and include exemplary embodiments of the present invention and illustrate various objectives and features thereof.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0022]     The window kit  10  shown in  FIG. 1  has three major molded components, the inside frame  11 , the outside frame  12  and the transparent panel  13 . These components are molded from plastics, reinforced plastic, fiberglass, carbon fibers, and combinations thereof or any other material of requisite characteristics. The components are molded with complementary surfaces to closely fit together in an assembled window with the exterior wall of a building (not shown) between the inside frame and the outside frame. Optimally, the window kit  10  is supplied along with building panels that have no pre-formed openings allowing the consumer to make openings and install the windows, as desired.  
         [0023]     As shown in  FIG. 1 ,  FIG. 3  and  FIG. 7 , this embodiment is molded to cover an opening cut, or otherwise formed, in a building wall constructed of weatherboard or molded to simulate weatherboard. The side edges of the inside frame  11  and the outside frame  12  are scalloped to match the cross section of overlapped boards or simulated overlapped boards. These scalloped edges form a seal with the building wall when the window is installed in the wall. As shown, the inside framell has a series of molded enlarged female fastener pins and the outside frame  12  has a matching series of male fastener pins which hold the frame together when they are interconnected. Of course, the fasteners may be reversed. The transparent panel  13  is sized and shaped to fit within and span the margins of the frame members. The panel  13  has a series of apertures through which pass the female fasteners of the inside frame  11  for assembly. As shown, the integrally molded transparent panel  13  has a group of simulated panes which are displaced from the general plane of the panel. This construction of the transparent panel  13  adds rigidity, as well as, the decorative appearance of individual window panes. The transparent panel may also be planar, if desired.  
         [0024]     As shown in  FIG. 2 , the exterior surface of the outside frame  12  has a lintel  14  and a decorative fascia  15  at the top and a sill  16  along the bottom connected by vertical frame rails  17  and  18 . The outside frame  12  also has a vertical mullion  19  and a horizontal mullion  20  joining the top with the bottom and the opposite sides, respectively. The mullions increase the strength and rigidity of the outside frame and contribute to the appearance when combined with the transparent panel in the final assembly.  
         [0025]     The edges of the vertical frame rails  17  and  18  have a depth D which is non-uniform, in this embodiment, to closely fit against a weatherboard appearing surface. The depth D is scolloped in a pattern to match the building surface and provide an outside window frame that is in the vertical plane. The depth and pattern of the edges of the vertical frame rails can be molded or otherwise formed to match the exterior surface of other buildings. The male fasteners  21  extend perpendicularly from the outside frame to a depth to engage the female fasteners of the inside frame.  
         [0026]     The enclosed surface  22  of the outside frame  12  is shown in  FIG. 4 . A channel  23  extends around the periphery of the enclosed surface. The male fasteners  21  are located within the channel  23 . The mullions  19  and  20  are also formed as open channels. Within the channel of the vertical mullion  19  are more male fasteners, one on each side of the horizontal mullion  20 . Of course, the location of these two fasteners could be reversed.  
         [0027]     The enclosed surface  22  of the outside frame is juxtaposed with the enclosed surface  24  of the inside frame  11 , shown in  FIG. 5 . The enclosed surface  24  also has a channel  25  about the periphery of the frame. A flange  26  extends latterly from the outer wall channel  25 . This flange  26  forms a seal with the interior wall of the building. Within the channel  25  are the complementary female fasteners  27  for engaging the male fasteners  21 . The fasteners  27  are of a height to extend through the thickness of the transparent panel  13 . The mullion  28  of the inside frame is channel shaped with two female fasteners located, one on either side of the horizontal channel shaped horizontal mullion  29 . The depth of the male fasteners and the height of the female fasteners are such that the outside mullions and the inside mullions contact the opposite sides of the transparent panel  13  in the final assembly. The male and female fasteners form a friction fit as they are telescoped together. Of course, adhesives or solvents may be added to the fasteners, if desired. In  FIG. 6 , the exterior surface of the inside frame is shown with the mullions  28  and  29  set inside the exterior surface of the frame. The scalloped vertical edges are also indicated.  
         [0028]      FIG. 7  illustrates the vertical side edges  30  of the inside frame  11 . The top of the frame is to the right and the bottom is to the left of the Figure. The side edge  30  is scalloped to closely contact the building inside wall in a weatherboard construction or simulated weatherboard construction. The depth of the side edges is such to provide a vertical inside frame on a weatherboard surface.  
         [0029]     The transparent panel  13 , as shown in  FIGS. 8 and 9 , is molded or otherwise formed as a unitary piece of a size and shape to fit within the inside and outside frames. The panel has complementary apertures  31  and demi-apertures  32  for the male and female fasteners of the inside and outside frames. Obviously, the panel can be frosted, tinted or translucent, if desired. The materials may include polymers, such as polyethylene, polycarbonate, or any other suitable moldable material. The panel has a general plane defined by the periphery  33  and the intersecting horizontal and vertical dividers  34  and  35 . As shown, 4 rectangular panes  36  are formed in relief from the general plane. This construction increases the strength and rigidity of the panel. Also, the mullions fit within the dividers in the final assembly producing the appearance of individual window panes. The rectangular shape of the panes can be changed to other geometrical shapes, if desired.  
         [0030]     A template  37 , shown in dotted lines in  FIG. 8 , is used to locate and determine the dimensions of the opening necessary for installation of the window  10 . The template  37  can be of paper or other material easily disposable. Other wise, the size of the opening may be documented merely as measurements in length and width.  
         [0031]     A number of embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiment but only by the scope of the appended claims.
