## Background
BACKGROUND OF THE INVENTION
1. Technical Field
This invention generally relates to fencing systems. More particularly, the invention relates to mounting brackets useful for installing horizontal rails to vertical posts. Specifically, the invention relates to a bracket for mounting a rail to a post in confined spaces and to a cover plate that snaps around the bracket once the rail has been retained within the bracket.
2. Background Information
It has become more common in recent years to use either vinyl or plastic products for constructing fences for yards or deck railings. While vinyl fencing is aesthetically pleasing and easy to maintain, the material poses somewhat of a problem for the contractor who must connect the various components together. It is especially problematic to connect horizontal vinyl rails to vertically extending posts in confined spaces.
There is therefore a need in the art for an improved bracket assembly for attaching horizontal rails to vertical posts.
SUMMARY OF THE INVENTION
The mounting bracket assembly of the present invention comprises a bracket that is secured to a vertical fence post and a cover plate that is snap-fitted over the bracket after the rail has been retained within the bracket. The bracket is preferably substantially U-shaped and is mounted in such a way that it is open at a top end. The rail is dropped into the U-shaped bracket and fasteners are used to secure the rail within the bracket. The cover plate is snap fitted over the bracket after the rail has been retained therein so as to conceal the fasteners. The cover plate provides an aesthetically pleasing finish to the connection between the post and rail.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1&2, there is shown a section of a deck railing 10 including a post 12, mounted to deck planking 14, and having a plurality of rails 16 secured thereto. A plurality of balusters 18 extend between the upper and lower rails 16. Rails 16 are secured to post 12 by way of mounting bracket assemblies in accordance with the present invention and generally indicated at 20.
Referring to FIGS. 3-9, there is shown a rail 16 connected to a post 12 by way of the mounting bracket assembly 20 in accordance with the present invention. Bracket assembly 20 comprises a bracket 22 and a cover plate 24.
In accordance with a specific feature of the present invention, bracket 22 has a back wall 26, a peripheral outer wall 28 extending outwardly away from the back wall 26 and having an opening 30 formed therein. Opening 30 preferably extends entirely across one end of bracket 22. Peripheral outer wall 28 is substantially U-shaped with the opening 30 therein extending from side section 28a across to side section 28b (FIG. 3). Back wall 26 of bracket 22 is also substantially U-shaped. Back wall 26 and peripheral outer wall 28 of bracket 22 substantially define a U-shaped receptacle 27 into which rail 16 may be received. Bracket 22 is complementary shaped and sized to receive an end of rail 16 therein. The distance between side sections 28a and 28b is therefore substantially equal to the width “A” of rail 16; and the distance between end section 28c and edge 29 is substantially equal to the height “B” of rail 16. It should, however, be understood that the bracket could alternatively be sized and shaped to receive rail 16 therein when it is turned through 90 degrees. In that instance, the distance between side sections 28a and 28c would have to be substantially equal to the height “B” of rail 16 and the distance between end section 28c and edge 29 would have to be substantially equal to the width “A” of rail 16. No matter which way rail 16 is to be oriented, an end of rail 16 is received within receptacle 27 in bracket 22. So, as is shown in FIG. 3, rail may be dropped or slid vertically into receptacle 27 through opening 30 (i.e., in the direction of arrow “C”) or, if space provides, may be slid horizontally into receptacle 27 in the direction of arrow “D”. Bracket 22 has a longitudinal axis “E-E” that runs substantially parallel to post 12 and a horizontal axis “F-F” that runs perpendicular to post 12.
Back wall 26 of bracket 22 defines a plurality of first apertures 32 therein. A plurality of first fasteners 34 are received through first apertures 32 to secure bracket 22 to a side wall 36 of post 12. Peripheral outer wall 28 defines a plurality of second apertures 38 therein. Second apertures 38 are provided to receive second fasteners 40 therethrough in order to secure rail 16 in shear within bracket 22. Side sections 28a, 28b of peripheral outer wall 28 preferably are also each provided with a flange 42 which extends from an outer edge 44 of bracket 22 through to a short distance inwardly from back wall 26 thereof. Flanges 42 preferably taper forwardly from back wall 26 through to outer edge 44 (FIG. 3). Outer edge 44 of peripheral outer wall 28 is preferably beveled and the beveling may include a front end 42a of flanges 42. End section 28c (FIG. 4) of peripheral outer wall 28 may also be provided with a pair of spaced apart ridges 46 thereon and a pair of notches 48 are provided at a top end of back wall 26. The purpose of ridges 46 and notches 48 will be described hereinafter.
Cover plate 24 is complementary shaped to surround bracket 22 and, more specifically, to encompass peripheral outer wall 28 thereof, including spanning the opening 30 between side sections 28a and 28b. Consequently, because bracket 22 is substantially U-shaped, cover plate 24 is substantially rectangular in shape. Cover plate 24 comprises a perimeter wall 50 that has a top end 50a, a bottom end 50b and sides 50c and 50d which together define an interior cavity 52 into which bracket 22 is received. The exterior surface of perimeter wall 50 may be provided with a decorative profile so as to give railing 10 a more decorative appearance. A slot 54 extends from a front edge 56 of cover plate 24 through to a back edge 58 thereof. The cover plate 24 is manufactured in such a way that it can flex and sides 50c and 50d can be pulled apart from each other as shown in FIG. 4. Tabs 60 are provided on each of sides 50c, 50d proximate back edge 58 thereof. As may be seen from FIG. 5, tabs 60 are positioned so that when cover plate 24 is snap-fitted over bracket 22, tabs 60 slide behind flanges 42. Tabs 60 will then be positioned between flanges 42 and side wall 36 of post 12. Cover plate 24 also has a lip portion 62 extending inwardly a short distance perimeter wall 50. Outer edge 44 of bracket 22 abuts lip portion 62 when cover plate 24 is snap-fitted around bracket 22. A pair of tapered tabs 64 are also provided on bottom end 50c alongside slot 54, with the widest part of tabs 64 being positioned proximate back edge 58 of cover plate 24. Tabs 64 are positioned to interlock with ridges 46 on bracket 22. Second tabs 66 are disposed on the interior surface of top end 50a of being positioned proximate back edge 58 of cover plate 24. Each second tab 66 further includes a downwardly extending projection 68 disposed proximate back edge 58.
Bracket assembly 20 is used to connect rail 16 to post 12 in the following manner. The installer selects the position on side wall 36 of post 12 where he wishes to install bracket 22. Back wall 26 is placed in abutting contact with side wall 36, preferably with opening 30 being position at the top of bracket 22. Fasteners 34, which are preferably stainless steel screws, are used to secure bracket 22 to post 12.
Rail 16 is then dropped into receptacle 27 defined by bracket 22 peripheral outer wall 28. The end 70 (FIG. 10) of rail 16 preferably is pushed into abutting contact with rear wall 26 of bracket 22. Second fasteners 40, which are preferably stainless steel screws, are then used to secure rail 16 within bracket 22.
Cover plate 24 is then positioned around bracket 22. In order to do this, side sections 50c and 50d of cover plate 24 are pulled apart (FIG. 4) and then cover plate 24 is moved downwardly over bracket 22. As the inner surface of the top end 50a of cover plate 24 engages edge 29 of bracket 22, projections 68 on cover plate 24 slide into notches 48 on bracket 22. The installer releases side sections 50c, 50d, which then snap inwardly toward each other and around bracket 22. When this occurs, tabs 60 slide behind flanges 42. The installer then engages side sections 50c and 50d of cover plate 24 proximate bottom end 50b and gently pushes side sections 50c, 50d inwardly toward each other. This causes tabs 64 to slide over ridges 46, thereby locking cover plate 24 in place. It should be noted that when in this position, cover plate 24 cannot slide outwardly away from post 12 and along rail 16. This is because projections 68 are engaged in notches 48 and tabs 60 are disposed behind flanges 42. Furthermore, side sections 50c and 50d cannot easily be moved outwardly away from each other because the tabs 64 are interlocked with ridges 46. Back edge 58 of cover plate 24 lies in abutting contact with side wall 36 of post 12, and lip 62 is in abutting contact with front edge 56 of bracket 22. All fasteners, 34 and 40 are hidden from view by cover plate 24 and the connection between rail 16 and post 12 is aesthetically pleasing. As may be seen from FIG. 10, a second bracket 22 and its associated cover plate 24 may be secured to one of the other side walls of post 12.
When cover plate 24 is positioned around bracket 22, cover plate 24 lies substantially at right angles to the horizontal axis “F-F” of bracket 22 and substantially axially aligned with longitudinal axis “E-E” of bracket 22.
In order to unlock tabs 64 from ridges 46 a thin object, such as the end of a flathead screwdriver can be inserted between a bottom wall of rail 16 and the inner surface of lip 62 and a small downward force is applied. Once tab 64 is disengaged from bracket 22, then side sections 50c and 50d are moved arcuately outwardly away from each other so that tabs 60 slide outwardly from behind flanges 42. Cover plate 24 is then slid slightly upwardly so that projections 68 slide out of slots notches 48. Cover plate 24 is then completely disengaged from bracket 22, each one of bottom sections 50b needs to be individually lifted over substantially prevents this arcuate motion from occurring without a reasonable amount of force being applied thereto.
Referring to FIGS. 11-13, there is shown a second embodiment of bracket assembly in accordance with the present invention and generally indicated at 120. Bracket assembly 120 is adapted to be used in association with a rail 116. Rail 116 is substantially T-shaped in cross-section and is adapted to be received within a bracket 122 mounted on a post 112. Bracket 122 includes a substantially T-shaped back wall 126 and a substantially U-shaped peripheral outer wall 128 which terminates in a flange 172 at the base of the crossbar 174 of the “T” shape on the back wall 126. All other components of bracket assembly 120 are substantially the same as those of bracket assembly 20. Bracket 122 is secured to post 112 by fasteners 134. Rail 116 gets dropped into the opening 130 between side sections 128a and 128b. The underside 176a of the flanges 176 on rail 116 abuts flange 172 on bracket 122. Fasteners (not shown) are then screwed into the side walls 116a of rail 116. Cover plate 124 is then snap fitted around bracket 122 by pulling the side sections 150c and 150d apart from each other and moving cover plate 124 downwardly until the interior surface of top end 150a engages upper edge 129 of bracket 122. Cover plate 124 interlocks and is secured to bracket 122 in the same manner as cover plate 24 and bracket 22.
It will be understood that while the figures illustrate bracket 22 secured to side wall 36 of post 12 with the opening 30 at the top so that rail 16 may be slid vertically into bracket 22 in the direction of arrow C, bracket 22 may be placed in any other desired orientation, e.g. with opening 30 effectively facing the front or back of the railing, or at an angle to the vertical, or even downwardly. The latter orientation is the least favored only for the reason that the end section 28c of bracket 22 assists in carrying the load of rail 16 and if opening 30 is disposed facing the deck planking 14, then the load of rail 16 is effectively carried by the fasteners 40, instead of a combination of the fasteners 40 and end section 28c. 
Furthermore, while a generally rectangular shaped rail and bracket assembly; and a generally T-shaped rail and bracket assembly have been illustrated and described herein, it will be understood that the complementary bracket and rail assembly can be of any desired shape and configuration without departing from the spirit of the present invention.
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.
