STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not Applicable.

BACKGROUND OF THE INVENTION

[0003] 1. The Field of the Invention

[0004] The present invention relates generally to brackets used to secure a horizontal member to a support structure. More particularly, but not necessarily entirely, the present invention relates to a multi-piece fence rail bracket assembly which not only attaches a horizontal member to a support structure, but also securely attaches the horizontal member to the bracket, while preserving the aesthetic quality of the fence system.

[0005] 2. Description of Related Art

[0006] Fence rails are typically attached to a support structure, such as a post or wall, with a bracket or other support member. The bracket typically functions to support the rail. The rail is often not secured to the bracket and the rail is able to slip out of the bracket when stress is placed upon the fence.

[0007] Some of the brackets disclosed in the prior art make installation of the fence rails difficult to accomplish. Installation of the fence rail using these prior art brackets is accomplished by first attaching two opposing brackets to opposing fence posts, then placing one end of the rail into one bracket, and bending the rail to force the other end of the rail into the opposing bracket.

[0008] Other prior art brackets, such as the fence rail clip disclosed in U.S. Pat. No. 5,788,224, includes a base for the bracket that attaches to the support structure. Installation of this bracket is accomplished by mounting a base to the fence post, then placing the bracket over the rail, and thereafter slidably attaching the bracket and rail to the base. Although this type of bracket system prevents the need to bend the rail to fit it in place, the base only secures a portion of the bracket resulting in less stability. Another disadvantage is that the rail is not fixedly attached to the bracket.

[0009] The prior art is also characterized by rail brackets with an open end which makes installation of the rail easier, and wherein the rail is attached to the bracket. However, these brackets are unsightly because the hardware used to attach the rail to the bracket is visible. For example, U.S. Pat. No. 5,547,169 discloses a rail bracket which is open on one end where the rail resides and wherein the rail attaches to the bracket, but the fastener used to attach the rail to the bracket is visible. The visible fasteners are unsightly, exposed to the elements, and create three dimensional features which can snag clothing or collect dirt.

[0010] The prior art is thus characterized by several disadvantages that are addressed by the present invention. The present invention minimizes, and in some aspects eliminates, the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.

[0011] The features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the invention without undue experimentation. The features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

[0033] Referring now to FIG. 1, there is shown an exploded perspective view of a fence rail cap bracket assembly generally indicated at 10. In one embodiment, the assembly 10 comprises three pieces. The first piece may be a bracket 12, with an open end 28, which may have a general “U” shape (hereinafter U-bracket). In alternative embodiments, the shape of the bracket 12 will be complementary to the contour of the outer surface of a fence rail, or other horizontal member. Referring again to FIG. 1, the “U” shape of the U-bracket 12 may be defined by a first wall 14, an opposing second wall 16, and a bottom wall 18 which form a rail support. The U-bracket 12 may also have a back wall 20. The back wall 20 of the U-bracket 12 may have holes 22, wherein the holes 22 may have an oval shape. In one embodiment, the U-bracket 12 has four holes 22 (as shown in FIG. 3). The holes 22 may extend through the back wall 20 of the U-bracket 12 and function to receive a fastening means, such as a screw 24, wherein the screws 24 attach the U-bracket 12 to a support structure (not shown), such as a post or wall. The oval shape of the holes 22 allows the U-bracket 12 to expand and contract with the environmental conditions, without interfering with the function of the U-bracket 12. The first wall 14 and the second wall 16 may each have a groove 26, wherein the groove 26 may be located on the outer surface of the first wall 14 and second wall 16. The grooves 26 may extend a majority of the width of said first wall 14 and the second wall 16 parallel to the bottom wall 18, and may be located near the open end 28 of the U-bracket 12.

[0034] Referring back to FIG. 1, the second piece of the assembly 10 may be a retention clip 30. The retention clip 30 may have a general “L” shape, defined by a first portion 32 and a second portion 34. Referring to now to FIG. 2D, there is shown two perspective views of the retention clip 30 of the fence rail cap bracket assembly 10 of FIG. 1. The first portion 32 may have a hole 36 which may be oval in shape, and which may extend through the first portion 32 and functions to receive a fastening means, such as a screw 24 (shown in FIG. 1). A recessed area 33 may be formed into the first portion 32 around the hole 36. The recessed area 33 functions to prevent the head of a screw 24 (shown in FIG. 1) from projecting above the surface of the first portion 32. The second portion 34 may have an aperture 38 with teeth 41 projecting inwardly from the aperture 38.

[0035] Referring now to FIG. 3, there is shown another perspective view of the U-bracket 12, the retention clip 30 and the cap 40, from the opposite side of the assembly 10 as shown in FIG. 1, with the addition of a rail 50 residing the U-bracket 12. The teeth 41 on the retention clip 30 may mesh with the complementary teeth 39 which form a catch on the back wall 20 of the U-bracket 12. The complementary teeth 39 may be positioned on a rear face of the back wall 20, whereas the first wall 14, the second wall 16 and the bottom wall 18 may form support for the rail 50 on the front face of the back wall 20. The retention clip 30 may be slid into position after a rail 50 is placed in the U-bracket 12. The second portion 34 of the retention clip 30 may be slid into the recessed area 64 of the U-bracket 12. The teeth 41 of the retention clip 30 may slide over the complementary teeth 39 on the U-bracket 12. Prongs 35 of the retention clip 30 may have elastic memory which allows the prongs 35 to flex. Once the teeth 41 of the prongs 35 pass over the complementary teeth 39 on the U-bracket, the prongs 35 may flex back to their original position and the teeth 41 on the prongs 35 of the retention clip 30 may mesh with the complementary teeth 39 of the U-bracket 12. The retention clip 30 may be attached to a rail 50 or other horizontal member by passing a screw 24 (shown in FIG. 1) through the hole 36 of the retention clip 30 and attaching the screw 24 to said rail 50.

[0036] Referring again to FIG. 1, the third piece of the assembly 10 may be a cap 40 that fits over the opening 28 on the U-bracket 12 and conceals the retention clip 30, screws 24, and end of the rail 50 (shown in FIG. 3). The cap 40 may have a general “U” shape. Alternative embodiments of the cap 40 will generally have a shape that complements the shape of the bracket 12. The cap 40 may have a first side 42, an opposing second side 44, and a top side 46. Referring to FIG. 3, the inner surface 43 of the first side 42 and the inner surface 45 of the second side 44 of the cap 40 may have ridges 48 which project from the inner surfaces 43 and 45. The ridges 48 may complement the grooves 26 on the outer surface of the first wall 14 and the second wall 16 of the U-bracket 12. The ridges 48 may define the lower boundary of a channel 52 in the cap 40. The channel 52 may receive an upper portion 56, defined on the lower side by the groove 26 of the U-bracket 12 and on the upper side by the top edge 58 of the U-bracket 12.

[0037] Referring now to FIG. 3, the upper most hole 22a of the U-bracket 12 may be centrally located near the top of the back wall 20 of said U-bracket 12. The upper most hole 22a may be located in a recessed area 64, wherein said recessed area 64 surrounds the upper most hole 22a and may be defined by a ledge 61. The recessed area 64 functions to receive the retention clip 30, such that said retention clip 30 will slide into the recessed area 64, between the U-bracket 12 and a support post or wall (not shown). An edge 62 of the upper most hole 22a may project outwardly from the surface of the recessed area 64 on the back wall 20. The edge 62 of the upper most hole 22a may have complementary teeth 39 projecting outwardly from the edge 62. Edges 62b, 62c and 62d of the other holes 22b, 22c and 22d, respectively, may also project outwardly from the surface of the back wall 20. An edge 59 of the back wall 20 of the U-bracket 12 may also project outwardly from the back wall 20.

[0038] Referring to FIG. 4A and FIG. 4B, there is shown two perspective views of alternative embodiments of the cap 40. The cap 40 may have a mouth 70 molded in the top side 46, on the side of the cap 40 opposite the post or other support structure (not shown). The mouth 70 can be of varying depths. FIG. 4A shows a deep mouth 70a, while FIG. 4B shows a shallow mouth 70b.

[0039] Referring to FIG. 5A and FIG. 5B, there is shown two perspective views of alternative embodiments of the U-bracket 12. The U-bracket 12 may have a mouth 72 formed in the bottom wall 18 on the side of the U-bracket 12 opposite the back wall 20. FIG. 5A shows a deep mouth 72a, while FIG. 5B shows a shallow mouth 72b. The mouths 70 and 72 of the cap 40 and U-bracket 12, respectively, function to receive pickets or panels of a fence (not shown).

[0040] Referring to FIGS. 6A and 6B, there is shown a front view of an assembled cap bracket assembly 10 supporting rails 50. FIG. 6A shows a fence with pickets 74 between the rails 50. The shallow mouth 70a (shown with dotted lines) of the upper U-bracket 12 receives the picket 74. The shallow mouth 70b of the lower cap 40 also receives the picket 74. FIG. 6B shows a fence with planks 76 between the rails 50. The deep mouth 72a (shown with dotted lines) of the upper U-bracket 12 receives the plank 76. The deep mouth 72b of the lower cap 40 also receives the plank 76. The ability to make the mouths 70 and 72 on the cap 40 and U-bracket 12, respectively, deeper provides more privacy to the fence owner. Referring to FIG. 6B, the deeper the mouths 70 and 72 are formed, the closer the fence plank 76 will be in relation to the post 80, or other support structure. The closer the plank 76 is placed to the post 80, the smaller the gap 78 between the plank 76 and the post 80, and more privacy is provided.

[0041] Referring back to FIG. 1, the outer surfaces of the cap 40 and the U-bracket 12 may be formed in an aesthetic manner. The U-bracket 12 may widen near the bottom and a ledge 92 may be formed on the outer surface. The widening of the U-bracket 12 near the bottom may also provide added structural strength for support of the rail 50. The bottom corner 90 of the U-bracket 12 may also be rounded. Referring now to FIG. 6A, the rounded corner 90 of the U-bracket 12 may blend into the sight line of the bottom edge 94 of the rail 50. The outer ledge 92 of the U-bracket 12 may blend into the sight line of a lower groove 96 in the rail 50. Referring back to FIG. 1, the cap 40 may have an upper rounded corner 98 and a rounded bottom edge 100. Referring to FIG. 6A, the upper rounded corner 98 of the cap 40 may blend into the sight line of the upper edge 102 of the rail 50. The rounded bottom edge 100 of the cap 40 may also blend into the sight line of an upper groove 104 of the rail 50.

[0042] It will be appreciated that the structure and apparatus disclosed herein is merely one example of a means for attaching a retention clip to a fence rail, and means for attaching a bracket to a support structure, and it should be appreciated that any structure, apparatus or system for attaching which performs functions the same as, or equivalent to, those disclosed herein are intended to fall within the scope of a means for attaching, including those structures, apparatus or systems for attaching which are presently known, or which may become available in the future. Anything which functions the same as, or equivalently to, a means for attaching a retention clip to a fence rail, or means for attaching a bracket to a support structure falls within the scope of these elements.

[0043] In accordance with the features and combinations described above, a preferred method of assembling the fence rail cap bracket assembly 10 includes the steps of:

[0044] (a) attaching the U-bracket 12 to a wall, post or other support structure (not shown) with screws 24;

[0045] (b) sliding a rail 50 into the open end 28 of the U-bracket 12;

[0046] (c) attaching the retention clip 30 to the U-bracket 12 by placing the aperture 38 of the retention clip 30 over the edge 62 of the upper most hole 22a and forcing the retention clip 30 downward until the teeth 41 of the retention clip 30 snap into meshing engagement with the complementary teeth 39 on the edge 62 of the upper most hole 22a;

[0047] (d) attaching the retention clip 30 to the fence rail 50 by placing a screw 24 through the hole 36 in the retention clip 30 and affixing the screw 24 into the rail 50; and

[0048] (e) placing the first side 42 and the second side 44 of the cap 40 over the first wall 14 and second wall 16 of the U-bracket 12, respectively, pressing the cap 40 down on the U-bracket until the ridges 48 of the cap 40 snap into the grooves 26 of the U-bracket.

[0049] The U-shape of the bracket 12 makes installation of a fence easier and less laborious. The installer merely attaches the U-shaped bracket 12 to a post or wall with screws 24, then slides the fence rail in the open end 28 of the bracket 12. The installer does not have to place the U-bracket 12 on the rail, then slidably attach the fence rail bracket to an attachment piece as disclosed in U.S. Pat. No. 5,788,224. In addition, applicant's system attaches the rail to the U-bracket 12 with a retention clip 30. The retention clip 30 may be attached to the top side of the rail 50 and to the rear portion of the U-bracket 12 instead of attaching screws 24 through the outside edges of a bracket 12 into the rail 50 as disclosed in the prior art. By attaching the rail 50 to the bracket 12 in this manner, the hardware used to attach the rail 50 to the U-bracket 12 may be hidden from view by the cap 40 and objects may also be prevented from snagging on the hardware. Applicant's method of attachment may also provide more support and strength to the assembled fence.

[0050] Applicant's use of a cap 40 in combination with the U-shaped bracket 12 may also provide aesthetic advantages. The cap 40 may cover the retention clip 30, screws 24, and open end 28 of the U-bracket 12. Also, the exterior shape of the cap 40 and U-bracket 12 may be formed to match the sight lines of the fence rail.

[0051] Those having ordinary skill in the relevant art will appreciate the advantages provide by the features of the present invention. For example, it is a feature of the present invention to provide a fence rail cap bracket assembly that is simple in design and operation. Another feature of the present invention is to provide a fence rail cap bracket assembly that securely attaches the rail to the bracket. It is a further feature of the present invention, in accordance with one aspect thereof, to provide a fence rail cap bracket assembly that has an aesthetically pleasing look. It is an additional feature of the invention, in accordance with one aspect thereof, to provide a fence rail cap bracket assembly that prevents the rail from sliding out of the bracket when stress is placed upon the fence.

[0052] It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been shown in the drawings and described above with particularity and detail, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made without departing from the principles and concepts set forth herein.
