BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to decorative trim for various construction projects. More particularly, the invention comprises a decorative trim cap for structural elements such as decks, posts and railings which provide protective cover against warping, splintering and cracking, in addition to providing an aesthetically pleasing trim to what are often rather course structures.  
           [0003]    2. Description of the Prior Art  
           [0004]    In the building of outdoor structures such as porches, decks and gazebos, structures which are often of a rather course construction, it is desirable provide an aesthetically pleasing trim to enhance the appearance of certain structural elements, as well as to protect the end grain of exposed elements such as vertical posts and railings from warping, splintering and cracking. To this end, others have presented a variety of solutions.  
           [0005]    U.S. Pat. No. 5,326,187, issued to St. Marie, et al., on Jul. 5, 1994, presents a cover for covering the upper rail of a railing. The upper cover has a top, bottom and side to encase the exposed surfaces of the rail. The cover has a curved top with a concave inner surface to be positioned adjacent the top of the rail. Longitudinal ribs on the inner surface spaces the cover away from the top surface of the railing. In contrast to the present invention, St. Marie, et al., is adapted to encase expanses of lateral surfaces, while providing no decorative features other than the arch upper surface of the cover.  
           [0006]    U.S. Pat. No. 5,794,390, issued to Oliveri, et al., on Aug. 18, 1998, presents a structural covering that is attachable to a rail of a railing that has a top, a pair of sides, ends, and a bottom, and that is attachable to a floorboard of a deck that has a top, a pair of sides, ends, and a bottom, while covering most of the rail of the railing and any exposed ends thereof and covering most of the floorboard of the deck and any exposed ends thereof so as to prevent splinters, hide knots, splintered wood, discolored wood and cracks in the wood. The patent to Oliveri, et al., is in distinct contrast to the present invention in that it is adapted to cover large expanses of lateral surfaces while providing no decorative features other than the arch of the upper surface.  
           [0007]    U.S. Pat. No. 6,062,519, issued to Baldassarre on Aug. 18, 1998, presents a a rail covering system for covering the railing of an outdoor deck to protect the railing from damage from weathering. The system includes an elongate strip having top and bottom faces, a pair of opposite ends, and a pair of sides extending between the ends of the strip. The bottom face of the strip is designed for resting on a top of a railing. Each of the sides of the strip has an elongate edge flange extending outwardly therefrom. In contrast to the present invention, the patent to Baldassare is adapted for covering an expanse of lateral surface and does not provide decorative scroll work to enhance the appearance.  
           [0008]    U.S. Pat. No. 6,286,884, issued to Speece on Sep. 11, 2001, presents a cap for the top surfaces of a truck bed sidewall providing a horizontally oriented top bed wall portion and an integral downwardly extending inner and outer portion. In contrast to the present invention, Speece is adapted to cover an expanse of lateral surface and offers no appreciable aesthetic appeal.  
           [0009]    None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.  
         SUMMARY OF THE INVENTION  
         [0010]    The present invention comprises an aesthetically pleasing end cap for structural members such as decks, posts and railings for outdoor structures such as porches, decks and gazebos. While warping, splintering and cracking are common concerns in such exposed applications, and it is desirable to protect the primary areas of concern (cut end edges and end grains) without having to encase the entire member, the cosmetic enhancement of what are often somewhat raw structural elements is often of equal concern. It is especially desirable to be able to protect these elements while providing aesthetic highlights to the overall structure.  
           [0011]    Accordingly, it is a principal object of the invention to provide a trim cap which will protect cut end edges and end grains from the elements.  
           [0012]    It is another object of the invention to provide a trim cap which will provide an aesthetic appeal to the structural element which it is protecting.  
           [0013]    It is a further object of the invention to provide an trim cap which is economical to manufacture, and therefore to purchase for use.  
           [0014]    Still another object of the invention is to provide a trim cap which is easy to install.  
           [0015]    An additional object of the invention is to provide a trim cap which is durable.  
           [0016]    It is again an object of the invention to provide a trim cap which is easy to maintain.  
           [0017]    It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.  
           [0018]    These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0029]    The present invention presents a system of decorative caps for structures such as, but not limited to porches, decks and gazebos which provide protection for areas which are most susceptible to weathering, splintering and cracking, such as open end grains and end cut edges. These caps may be brake formed of flat rolled metals, such as, but not limited to, galvanized steel, brass or bronze, or aluminum, or molded of a high impact polymer or similar material. For the purposes of disclosure, brake formed elements will be disclosed, revealing flat blank and formed depictions. It would be evident to one skilled in the art that molded elements would be similar in appearance to the formed views of the brake formed elements disclosed.  
         [0030]    [0030]FIGS. 1 and 2 depict a deck top corner cap  10 . This element would typically be used on the top surface of the corner of a deck where a vertical post is not present, providing protection and aesthetic appeal primarily to the deck surface and protection to the edges of the decking planks at the corner.  
         [0031]    Referring first to FIG. 2, deck top corner cap  10  consists of a generally rectangular (typically square) corner top plate  12  having two adjacent edges  14  which are substantially linear, normal to one another and, typically, of equal length. A corner side plate  16  is formed along each of the two adjacent edges  14 , each corner side plate  16  being substantially rectangular, having a length equal to that of the edge  14  of corner top plate  12  with which it is contiguous and a width equal to that of the other corner side plate  16 . A notch is formed in the blank for deck top corner cap  10  in the quadrant formed between the widths of the two corner side plates  16 . The two edges  18  of corner top plate  12  opposite the two edges  14  are of a freeform shape, thereby creating a decorative design to the overall corner top plate  12 . Typically, corner top plate  12  is symmetrical along a diagonal line from the juncture of the two edges  14  to the juncture of the two edges  16 . It would be evident to one skilled in the art, however, that corner top plate  12  could be totally asymmetrical, thereby providing a different aesthetic effect. A plurality of mounting holes  20  in corner top plate  12  and corner side plates  16  allow for attachment of deck top corner  10  over a corner of a deck structure. The blank of FIG. 2 is brake formed along each of the edges  14  to form the deck top corner cap  10  of FIG. 1.  
         [0032]    Turning now to FIG. 4, a blank for a deck side corner cap  30  consists of a pair of substantially rectangular corner plates  32  abutting one another along corner line  34 . Each corner plate  32  additionally abuts a substantially triangular bottom plate  36  along a bottom line  38 , corner line  34  being substantially centered upon and normal to bottom line  38 . A notch of approximately 90° is formed in the blank for deck side corner cap  30  between the two bottom plates  36  at their juncture with corner line  34 , such that an edge  40  or each bottom plate  36  forms an angle of approximate 45° with respect to bottom line  38 . Outer edges  42  of corner plates  32  may be of a totally freeform shape or a combination of linear and freeform to provide an aesthetic appearance, as may outer edge of bottom plate  36 . However, the two corner plates  32  and two bottom plates  36  are typically symmetrical with one another, although, again, they may be totally asymmetrical. A plurality of mounting holes  46  in corner plates  32  and bottom plates  36  allow mounting over the side edges of a deck corner. The blank for the deck side corner cap  30  of FIG. 4 is brake formed along corner line and bottom line  38  to form the finished deck side corner  30  of FIG. 3, with the bottom edges  40  of the two bottom plates  36  abutting in the finished deck side corner cap  30 . Deck side corner cap  30  is typically used to cover the ends of the stringers surrounding a deck at a corner.  
         [0033]    Turning our attention now to FIG. 6, a rail corner cap  50  consists of a substantially square rail top plate  52 , and two substantially square rail side plates  54 , each rail side plate  54  contiguous with rail top plate  52  along one of two substantially straight, adjacent edges  56 . A straight edge  58  of each rail side plate  54  is formed as a continuation of edges  56 , with an open notch formed in the blank in the quadrant between the edges  58 . The two edges of rail top plate  52  opposite edges  56  and the two edges of rail side plates  54  opposite edges  56  and  58  may be of either a totally freeform shape or a combination of freeform and linear, to thereby provide an aesthetically pleasing appearance. Typically the two rail side plates  54  would be symmetrical to one another, and rail top plate  52  would be symmetrical along a diagonal from the intersections of the two edges  56  to the intersection of the two opposite sides. A plurality of mounting holes  60  in rail top plate  52  and rail side plates  54  allow connection of rail corner cap  50  to a deck railing at a corner joint. The blank for the rail corner cap  50  of FIG. 6 is brake formed along each of the edges  56  to form the rail corner  50  of FIG. 5.  
         [0034]    Now referring to FIG. 9, corner plate  70  consists of two substantially rectangular plate ends  72  joined along a joint  74 . The top  76  and bottom  78  edges of corner plate  70  are substantially linear, adapted to follow the lines of the edges of stringers running around the perimeter of a deck, although portions may be of a freeform shape, particularly at their junctures with the ends  80  of plate ends  72  opposite joint  74 . The ends  80  may be of either a totally freeform shape or a combination of freeform and linear, in order to provide a pleasing aesthetic appearance. A plurality of mounting holes  82  in corner plate  70  facilitate mounting of corner plate  70  along a stringer around the perimeter of a deck. The blank for the corner plate  70  of FIG. 9 is brake formed along joint  74  to form the corner plates  70  of FIGS.  7  (substantially a 90° angle), and  8  (substantially a 45° angle). The angles depicted in FIGS. 7 and 8 could, of course, be manually adjusted during installation, especially in sheet metal embodiments.  
         [0035]    In each embodiment herein presented, the shape is strictly illustrative, as each embodiment may be produced in a myriad of different aesthetic variations. It would be evident to one skilled in the art that, in addition to the aesthetically pleasing lines of each embodiment, surfaces could be embossed with various textures or graphic designs to further enhance their appearance. Likewise, the suggested use of each embodiment is strictly illustrative, as installational applications for any one embodiment are limited only by the imagination of the user.  
         [0036]    It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.

Summary:
A trim cap providing aesthetically pleasing protection and reinforcement to structural members such as decking and railing corners of structures such as porches, decks and gazebos is discloses. Deck top corner, deck side corner, rail corner and butt joint caps have aesthetically pleasing non-linear lines and/or embossed graphic or textural designs which set them apart from the purely structural applications of prior art brackets and caps.
