BACKGROUND OF THE INVENTION
1. Technical Field
This invention generally relates to connectors. More particularly, the invention relates to fence rail clips which are used to connect vinyl fence rails and fence posts together. Specifically, the invention relates to an adjustable clip that is mounted onto a fence post and includes covers to hide the mounting mechanism.
2. Background Information
It has recently become more common to use either vinyl or plastic products for constructing fences and deck railings. While vinyl fencing is aesthetically pleasing and easy to maintain, it is more difficult to connect together than wood. One of the more problematic areas is the connection between rails and vertical fence posts. The instant inventor has proposed a novel adjustable connector for joining fence rails to fence posts in the previously filed applications referenced above. In these previous applications two mechanisms have been disclosed for securing the rail clip to the fence post. The first mechanism comprised a bracket which is secured to the fence post and a rail clip having a complementary sized and shaped recess formed in its rear surface and being slidably engageable with the bracket mounted on the post. The second connector mechanism proposed by the instant inventor was the provision of lateral areas on the rail clip which included slots having apertures formed in them. Screws were inserted through the apertures and into the fence post. This second connector mechanism works well to secure the rail clip to the post but, because the screws are visible, the overall appearance of the connection was not entirely aesthetically pleasing.
There is therefore a need in the art for an improved rail clip for attaching fence rails to fence posts and which presents a clean and finished appearance without the mounting mechanism for the clip on the post being visible.
SUMMARY OF THE PRESENT INVENTION
A fence rail clip for attaching a fence rail to a vertical fence post. The rail clip has a base with a raised central area flanked by two lateral areas and a rail connector that, vertically or horizontally, slidingly engages the central area of the base. The lateral areas include apertures through which fasteners are inserted to connect the clip to the fence post. A cover snap-fits over each lateral area to hide the fasteners and give the rail clip a clean and aesthetically pleasing appearance.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1 there is shown a fence, generally indicated at 10, constructed from a plurality of rails 12 and posts 14 connected together by rail clips 16 in accordance with the present invention. While fence 10 is shown with rails 12 being secured substantially at right angles to posts 14, it will be understood that rail clips 16 allow the position of a rail to be slidably adjusted on clip 16 and consequently rails 12 can be secured to posts 14 at any desired angle.
Referring to FIGS. 2-5, clip 16 comprises a base 18 and rail connector 20. Base 18 preferably is a single, molded piece that is generally rectangular when viewed from the front (FIG. 3) and is generally semi-circular when viewed from the top or bottom (FIG. 4). Base 18 comprises a central area 22 flanked by lateral areas 24. Central area 22 has first and second planar walls 26, 28 connected together by an arcuate outer wall 30. First planar wall 26 has a length A-A′ (FIG. 4) and second planar wall 28 has a length B-B′ with length A-A′ preferably being shorter than length B-B′. Central area 22 extends outwardly beyond lateral areas 24 thereby forming side walls 34 and a semi-circular groove 36 is cut into each side wall 34. Rail connector 20 engages in groove 36, allowing connector 20 to slide along outer wall 30 and allowing the position of rail connector 20 to be adjusted. The interlocking connection of rail connector 20 and base 18 has been previously described in U.S. patent application Ser. No. 10/246,285 and U.S. Pat. No. 6,698,726 issued to the present inventor and the entire specifications of these two documents are incorporated herein by reference.
In accordance with one of the specific features of the present invention, a cover 38 is provided for each lateral area 24. Each lateral area 24 has an outer wall 40 which extends outwardly from side walls 34 of central area 22 and is substantially semi-circular when viewed from the bottom (FIG. 4). Outer wall 40 broadens to form shoulders 42 that flank a recessed area 44 ( FIG. 3) and terminates in an outer edge 45 that lies substantially parallel to side wall 34. Recessed area 44 has a bottom wall 46 and an interior wall 48 (FIG. 4) which extends upwardly therefrom. Interior wall 48 lies substantially parallel to side wall 34 of central area 22. A pair of ribs 50 extend outwardly from bottom wall 46 and terminate at outer wall 40. As may be seen from FIGS. 4 & 5, apertures 52 are formed in bottom wall 46 and fasteners 54 are inserted therethrough to secure clip 16 to post 14. First slots 56 are formed in the underside of bottom wall 46 and at least one second slot 58 is formed in the interior wall 48 of each lateral area 24. Second slot 58 extends into an interior cavity 60 of central area 22.
Each cover 38 is received over outer wall 40 and snap fits into place over lateral area 24 as will be hereinafter described. Cover 38 is substantially C-shaped (FIG. 4) and includes a rear wall 62 with has an arcuate wall 64 extending outwardly therefrom. Arcuate wall 64 is complementary sized and shaped to abut outer wall 40 of lateral area 24. A pair of tabs 66 (FIG. 5) extend inwardly from the base of rear wall 62 and are positioned to be received within first slots 56 of lateral areas 24. Tabs 66 are complementary in size and shape to first slots 56. A detent 68 extends inwardly from the underside of arcuate wall 64 of cover 38 and is positioned to be received within second slot 58 of rail clip 16. Detent 68 preferably includes a lip 70 which extends upwardly toward arcuate wall 64 and interlocks with the interior side wall 72 of clip 16 (FIG. 5).The positioning and the sizes of tabs 66 and detent 68 and the presence of lip 70 allow cover 38 to be snap-fitted over lateral area 24. The lip 70 on detent 68 also prevents easy removal of cover 38 from lateral area 24.
The present invention is used in the following manner. The rail clip 16 is positioned against the post 14 in the manner shown in FIG. 4. Fasteners 54 are inserted through apertures 52 and are screwed into post 14. A cover 38 is then moved laterally, in the direction of Arrows “C” and “D” respectively (FIG. 3) over the outer wall 40 of the corresponding lateral area 24. The underside of arcuate wall 64 of the cover 38 abuts outer wall 40 and shoulders 42 of lateral area 24. Cover 38 is slid inwardly over outer wall 40 and shoulders 42 toward central area 22 until detent 68 slides through second slot 58 in interior wall 48 and tabs 66 are received in first slots 56. As cover 38 continues to be moved inwardly, detent 68 deflects slightly downwardly as lip 70 slides into second slot 58 and then into interior cavity 60 of rail clip 16. Lip 70 slides out of second slot 58 and into cavity 60 and springs upwardly and into abutting contact with interior side wall 72 of clip 16. In this position, cover 38 is locked or snap-fitted onto rail clip 16. In this position, cover 38 hides fasteners 54, ribs 50 and all other features of lateral area 24. Clip 16 therefore presents an aesthetically appealing outer surface as is shown in FIG. 2 with no connection mechanism between clip 16 and post 14 being visible. When rail connector 20 is engaged in groove 36 and the position of rail connector 20 is slidably adjusted on the arcuate outer wall 30 of central area 32, the inner edge 20a (FIG. 4) of rail connector 20 rides along the outer surface 64a of arcuate wall 64 of cover 38.
If the user desires to remove clip 16 from post 14 or to simply tighten fasteners 54, the user grasps cover 38 and pulls cover 38 outwardly away from central area 22 (as is indicated by the Arrows “E” and “F” respectively in FIG. 2), rotating cover 38 slightly upwardly as he does so. This causes lip 70 of detent 68 to disengage from interior side wall 72 of clip 16 and detent 68 slides out of second slot 58. At the same time, tabs 66 slide out of first slots 56 and cover 38 slides off outer wall 40 of lateral areas 24. The user can then loosen or tighten fasteners 54 as desired and then, if required, covers 38 can be snap-fitted to rail clip 16 again in the manner previously described.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention is an example and the invention is not limited to the exact details shown or described.
