The present invention relates generally to devices for use in construction of a fence or other structure in which horizontal rails are suspended between upright posts, and more particularly to devices for temporarily supporting the two ends of the rail to allow properly aligned installation by a single person.
Brackets and other devices for supporting of a fence rail between two fence posts during construction of a fence have previously been proposed to reduce labour requirements by allowing a single installer properly align and fasten the rail in place, thus avoiding the need for two installation personnel to align, hold and fasten the rail.
Among the solutions proposed in the prior art are permanent hardware brackets that are mounted to neighbouring posts, and to which the rail is subsequently fastened, whereby the brackets become a permanent part of the fence structure. These brackets are typically formed from a bent metal plate with a galvanized coating, and thus detract from the aesthetic of a purely wooden fence construction in which wooden rails are directly fastened to wooden posts. The permanent brackets also represent an added material cost relative to a purely wooden construction.
Other solutions instead employ supports that are removably fastened to the neighbouring posts to hold the respective ends of the rail in place until the rail ends is fastened directly to the posts, at which point the temporary supports are removed from the posts and re-used to hang the next rail between the next pair of neighbouring posts.
One such solution is shown in U.S. Pat. No. 5,673,903, where a temporary fence rail support features a C-shaped frame clamped in place around three sides of a post in order to support the end of a rail in an offset position where a face of the rail abuts against an outer side of the post. The device is incapable of placing the rail in an inline position contained entirety between the two posts with the ends of the rail abutted against lateral sides of the posts that face toward one another. The device also lacks means for automatic alignment in a properly squared orientation on the post.
U.S. Patent Application Publication 2014/0138891 discloses a temporary fence rail support in the form of a flexible strap that hangs from a fastener driven into the fence post. The flexible strap is only capable of providing support, and does not provide any guidance for proper alignment of the rail on the post. The reference once again focuses on fastening of fence rails in offset positions at outer sides of the fence posts.
U.S. Pat. No. 9,344,674 discloses another temporary fence rail support that once again is specifically designed to support a rail board in offset relation to the post at the outer side thereof, and lacks any means for self-alignment of the support on the post to ensure proper alignment of the rail.
U.S. Pat. No. 683,909 discloses a scaffold bracket with a closed frame that spans fully around an upright to post on all four sides thereof. The frame carries a pivotal dog or grip block at one outer side of the post while placing a rail holder at the opposing outer side of the post to once again support the rail in an offset position. The holder is removable from the frame in order to open up the respective end thereof and enable placement of the frame in an embracing position around the post. Once again, the design is intended for offset rail placement, and is not operable to support a rail in an inline position between lateral sides of the posts.
U.K. Patent GB593044 discloses permanent metal brackets mountable to the lateral sides of neighbouring fence posts for in-line placement of the rail between the two posts. However, the brackets rely on pre-drilled bores in the posts to guide the placement of the brackets in properly aligned positions thereon, and the rails are fastened to the brackets, which remain in place as a permanent part of the fence structure.
U.S. Pat. No. 3,373,988 discloses a removable beam seat for supporting a beam horizontally between a pair of vertical columns. Designed for use with structural steel, the beam seat employs bulky, complex design that occupies all four sides of the column, features two clamps for tightening on the column in one direction, and a wedge for mechanism for tightening on the column in the other direction.
U.S. Pat. Nos. 8,806,729, 9,033,314 and 9,181,725 discloses devices for supporting wooden rails on round pipe-shaped fence posts, but once again are designed to place the rails in offset relation outside the posts, rather than in inline relation between the posts.
International PCT Application Publication WO201541524 discloses a temporary fence panel support that is designed for in-line placement of a fence panel between two posts. The device simply hangs from a top end of the post without clamps or other moving parts that are relied on in many of the other prior art solutions summarized above. The lower part of the support that carries the bottom of the fence panel is automatically placed at a suitable elevation downward from the top of the post, but the support lacks any means for properly squaring the panel relative to the post. Instead, the installation process relies on separate panel connectors to set the final position in which the panel is to be fastened in place, specifically by fastened attachment to the connectors, not to the posts themselves.
In view of the forgoing shortcomings of the prior art, there remains room for improved devices and techniques for temporary support of rail members between neighbouring upright posts during construction of a fence or other post/rail structure.
According to a first aspect of the invention, there is provided a device for temporarily supporting an end of a rail during installation thereof between a pair of upright posts, said device comprising:

Preferably there is a tape measure slot in which a catch tab of a tape measure in insertable to enable a post-to-post measurement between the two posts after installation of the device.
Preferably the shoulder comprises a shoulder flange projecting outwardly away from the outer face of the bracket to define a shoulder width that exceeds a thickness dimension of the bracket measured between the inner and outer faces thereof.
Preferably the tape measure slot is located at an intersection of the shoulder flange and the outer face of the bracket. Preferably the bracket comprises a main portion defining the inner and outer faces and having a vertical leg from which a horizontal leg reaches perpendicularly outward at an elevation below an upper end of the vertical leg, the seat resides atop the horizontal leg, the upright shoulder resides at an inner side of the vertical leg from which the horizontal leg extends, and the bracing flange resides at an opposing outer side of the vertical leg.

Preferably the bent plate is L-shaped and consists solely of said vertical and horizontal legs.
Preferably a fastening hole penetrates the bracket from the outer face thereof to the inner face thereof to enable temporary fastening of the bracket to the lateral side of the post through said fastening hole.
In one embodiment, a seating depth of the bracket measured from the shoulder to the bracing flange equates to a half-width of the post minus a half-thickness of the rail, whereby the bracket is configured to center the rail across the lateral side of the post.
In another embodiment, a seating depth of the bracket measured from the shoulder to the bracing flange equates to a full-width of the post minus a full-thickness of the rail, whereby the bracket is configured to place the rail in flush relation to a third side of the post that intersects the lateral side of the post at which the bracket is placed and that is situated opposite the adjacent outer side of the post that is embraced by the bracing flange.
Preferably there is a visual marker situated on the bracket and spaced above the seat by a distance that equals a width of the rail, whereby placement of the visual marker in alignment with a top end of the post places a top edge of the rail flush the top end of the post when the rail is placed atop the seat.
Preferably the visual marker is an upper end of the bracket or an upper end of the shoulder.
According to a second aspect of the invention, there is provided a device for temporarily supporting an end of a rail during installation thereof between a pair of upright posts, said bracket comprising:

Preferably, achievement of the squared position in step (a) comprises placing a visual marker of the bracket device in alignment with a top end of the first post, and thereby automatically setting an elevation of the seat at a downward distance the top end of the post that equals a predetermined width dimension of the rail so that placement of the rail on the seat in a widthwise-up orientation automatically places a top edge of the rail flush with the top end of the post.
Preferably the visual marker of the bracket device is an upper end of the bracket device or an upper end of the shoulder thereof.
Preferred embodiments of the invention will now be described in conjunction with the accompanying drawings in which:
The present invention is particularly useful for wooden fence construction, where the posts and rails are respective pieces of dimensional lumber, for example 4×4-inch or 6×6-inch wooden posts and 2×4-inch or 2×6-inch wooden rails, though similarly configured brackets could likewise be used with posts and rails of various sizes and material compositions, whether for fence construction or construction of other structures that likewise requiring stringing of horizontal rails between neighbouring upright posts. It will be appreciated that the terms vertical and horizontal are used herein solely for the purpose of differentiating between the upright posts 100, 102 and the laterally spanning rail 104 suspended therebetween, and is in no way intended to specify that the posts and rails must occupy truly vertical and truly horizontal orientations, as in practical terms, the actual orientations may deviate slightly from true horizontal and vertical due to imperfections in the placement and shape of the posts and rails.
With reference to
The L-shaped main portion 12 features a vertical leg 20, and a horizontal leg 22 that reaches perpendicularly outward from the horizontal leg at the bottom end thereof so as to reside at an elevation spaced downwardly from the top end 20a of the vertical leg 20. The terms vertical and horizontal are again used to generally denote the orientations in which the described elements reside during use of the bracket when installed on a respective vertical post. The two legs 20, 22 of the planar main portion 12 are coplanar with one another, thus occupying a shared primary plane in which a majority of the bent metal plate's overall surface area resides. The two legs 20, 22 collectively define opposing inner and outer L-shaped faces 24, 26 of the bracket that lie opposite one another across the plate thickness of planar main portion 12 and face outwardly from the primary plane in opposite directions.
The bracing flange 14 spans a full height of the bracket from the bottom perimeter edge of the horizontal leg to the top end 20a of the vertical leg. The bracing flange resides at a vertically upright outer perimeter edge 20b of the vertical leg 20 at a side thereof opposite that from which the horizontal leg 22 extends. The bracing flange 14 lies normal to the planar main portion 12, and juts perpendicularly outward from the inner face 24 thereof. The seating flange 16 and the shoulder flange 18 also lie normal to the planar main portion 12, but project perpendicularly outward from the opposing outer face 26 so as to extend in the opposite direction than the bracing flange 14. The seating flange 16 fully spans a horizontal upper perimeter edge 22a of the planar main portion's horizontal leg 22, and thus lies horizontally perpendicular to the vertically upright bracing flange 14. The shoulder flange 18 spans a vertically upright inner edge 20c of the vertical leg that lies opposite to the upright outer edge 20b from which the bracing flange 14 projects. The shoulder flange 18 thus lies in parallel relation to the bracing flange 14 across the vertical leg, and in perpendicular relation to the seating flange 16 above a proximal end thereof at or near the intersection point between the horizontal upper edge 22a of the horizontal leg 22 and the upright inner edge 20c of the vertical leg 20.
A hanging aperture 28 penetrates the vertical leg 20 of the planar main portion 12 near the top end 20a thereof, and as shown may have an elongated-slot shape in the horizontal direction in which the bracing flange 14 and shoulder flange 18 are separated from one another. This hanging aperture 28 is useful to enable hanging support of the two brackets of the system on a merchandising display in a retail sales environment. A fastening hole 30 penetrates the horizontal leg 22 of the planar main portion 12 from the inner face 24 to the opposing outer face 26 thereof at a generally central point on the horizontal leg 22. It is via this fastening hole 30 that a suitable fastener, e.g. a threaded screw fastener 32, is driven through the planar main portion 12 of the bracket 10 in order to support the bracket in an installed position on a respective fence post.
This embraced fitting of the bracket 10 over the corner 100c of the post so that the bracing flange 14 of the bracket abuts in flush conforming contact against the front outer side 100b of the post while the main portion 12 of the bracket abuts in flush conforming against the lateral side 100a of the post automatically squares the bracket 10 in relation to the corner 100c of the post. This automatically places the horizontal leg 22 of the bracket 10 in perpendicular relation to the corner 100c of the post, and automatically places the vertical leg 20 of the bracket in parallel relation to the corner 100c of the post. Accordingly, the seating flange 16 situated atop the horizontal leg 22 of the bracket spans perpendicularly across the lateral side 100a of the post 100 from the front corner 100c of the post toward the opposing rear corner thereof, while projecting perpendicularly outward from the lateral side 100a of the post toward the neighbouring post 102. The seating flange thus creates a support seat spanning horizontally across the lateral side of the post to receive the bottom edge of the rail atop said seat in a position placing the end of the rail in abutting contact or close adjacency to the lateral side 100a of the post 100.
Meanwhile, the shoulder flange 18 stands perpendicularly upright from the seating flange 16 in parallel relation to the corner 100c of the post at a spaced distance inwardly therefrom along the lateral side 100a thereof to define an upright shoulder against which a face 104a of the rail can be placed. Accordingly, with the bottom edge of the rail 104 seated atop the seating flange 16, pushing the face 104a of the rail 104 against the upright shoulder flange 18 aligns the face 104a of the rail in parallel alignment to the corner 100c of the post, while the seating flange 16 holds the bottom edge of the rail in perpendicular relation to the corner 100c of the post. Accordingly, simple placement of the bracket against the lateral side of the post with the bracing flange 14 embraced against the adjacent front outer side 100b of the post automatically squares the bracket in proper alignment on the post, so that once the bracket is fastened to the post through fastener hole 30, seating of the respective end portion of the rail 104 against the perpendicular seating and shoulder flanges 16, 18 of the bracket will automatically place the rail in squared alignment with the post at the lateral side thereof.
In the first embodiment, the height by which the vertical leg 20 and shoulder flange 18 reach upward from the seating flange 16 is equal to an edge-to-edge face width dimension of the rail, for example measuring 3.5-inches to match the finished edge-to-edge face width of a 2×4 lumber rail. As a result, seating the end of the rail atop the seating flange 16 acts to place the top edge 104b of the rail 104 flush with the top end 20a of the bracket 10. This way, when the bracket is used on a flat-top fence post 100, the top end 20a of the bracket 10 serves as a visual indicator by which the appropriate mounting height of the bracket on the post can be gauged during installation of the bracket onto the post. When placing the bracket in its squared-off position embracing the corner 100c of the post, the top end 20a of the bracket 10 is aligned flush with the flat top end 100d of the post. This way, when the rail 104 is seated on the bracket 10, the top edge 104b of the rail 100 will automatically be placed in flush alignment with the flat top end 100d of the post 100. Such top end alignment of the bracket and rail is useful when constructing a “capped rail” fence, where capping pieces of lumber are subsequently placed in edge-out orientation in positions mounted atop the installed rails and spanning along the fence line from rail to rail overtop of the flat-topped posts. Alternatively, for a different look, the brackets and rails may be set a short elevation downward from the top ends of the posts in order to position the rails further down the post, for example for the purpose of a “capped post” fence construction, where the posts feature ornamentally shaped top ends situated above the rails of the fence.
Having described the structure of the left bracket and the process of mounting the left bracket on the left post 100, attention is turned to
So, to install the rail 104, a single-person installer places the left bracket 10 on the left post 100 in a self-squaring position thereon embracing the corner 100c thereof, and removably attaches the left bracket 10 to left post 100 in this squared position by driving a single threaded fastener 32 through fastener hole 32 with a cordless screw drive driver. In the same manner, the same single-person installer likewise places and fastens the right bracket 10A on the right post 102 in the corner-embracing self-squaring position thereon. Each bracket 10, 10A features a tape measure slot 34 therein at the upright inner edge 20c of the vertical leg 20 of the bracket's main portion 12, where the plane of the shoulder flange 18 intersects the plane of the bracket's outer face 26. This way, after installation of one or both brackets, the single-person installer can insert the catch tab of a tape measure into the tape measure slot 34 of one installed bracket to measure the distance from this tape measure slot 34 at the lateral side of that post to the nearest lateral side of the neighbouring post. This post-to-post measurement can then be used to accurately cut the rail 104 to optimally fit this post-to-post distance. With both brackets installed, the accurately cut rail 104 is then lifted up onto the seating flanges 16 of the two brackets 10, 10A, and pushed flush against the shoulder flanges 18 thereof. The two ends of the rail are then fastened one-by-one to their respective posts 100, 102 by driving additional screw fasteners 36 diagonally through the end of the rail from one or more faces/edges thereof into the post. With the rail fastened in place to the posts, the bracket holding fasteners 32 are removed, thereby freeing the brackets 10, 10A from the posts, and leaving behind an aesthetically pleasing, bracket-free, wood-to-wood joint between the post and rail. The brackets 10, 10A are then re-used to repeat the same rail installation process on the next pair of neighbouring fence posts.
The vertical leg 120 of the oversized L-shape blank also has an inner bend line 204 running from the top end 120a of the vertical leg 120 downwardly past the inside corner of the L-shape where the inner edge 120c of the vertical leg 120 and the upper edge 122a of the horizontal leg 122 intersect. The horizontal leg 122 of the oversized L-shape blank has an upper bend line 206 running parallel to the upper edge 122a of the horizontal leg 122 from a distal end 122b of the horizontal leg furthest from the vertical leg. The upper bend line 206 of the horizontal leg intersects the inner bend line 204 of the vertical leg at a lower end of the inner bend line 204. A slotted or notched cut-out 208 reaches inwardly from the inner corner of the L-shaped blank to the intersection point of the inner and upper bend lines 204, 206 of the vertical and horizontal legs 120, 122, thereby separating the seating flange portion 116 that resides between the horizontal leg's upper edge 122a and upper bend line 206 from the shoulder flange portion 118 that resides between the vertical leg's inner edge 120c and the outer bend line 204. The bracing flange portion 114 is similarly defined as the area between the outer edge 120b of the vertical leg 120 and the outer bend line 202.
The L-shape of the blank 200 is thus referred to as oversized, because the horizontal width of it's vertical leg 120 embodies both the vertical leg of the finished bracket's main portion 12, plus the integrally connected flange portions 114, 118 that are subsequently bent from the plane of the main portion to define the bracing and shoulder flanges 14, 18; while the vertical width of the blank's horizontal leg 122 embodies both the horizontal leg 20 of the finished bracket's main portion 12, plus the integrally connected flange portion 116 that is subsequently bent from the plane of the main portion 12 to define the seating flange 16. The hanging aperture 28 is punched or cut in the vertical leg 120a of the blank 200 between the inner and outer bend lines thereof, and the tape measure slot 34 is punched or cut in the vertical leg 120a of the blank 200 along the inner bend line. The fastening hole 30 is drilled, punched or cut in the horizontal leg 122 of the oversized L-shaped blank 200.
To form the finished bracket, the blank 200 is bent by 90-degrees across this outer bend line 202 to create the bracing flange 14 of the finished bracket. The blank is bent ninety degrees about the inner and upper bend lines 204, 206 in a direction opposite that of the bending operation performed at the outer bend line 204 to create the seating and shoulder flanges 16, 18 of the bracket that extend in the opposite direction from the bracing flange 14.
It will be appreciated that the blank 200 and the main portion of the resulting bracket 12 need not necessarily consist solely of an L-shaped area, and for example, other shapes may similarly have diverging legs for defining a horizontal support seat on which the underside of the rail may be seated, and an upright shoulder situated above the support seat for contact by the face of the rail. In the illustrated embodiment, perpendicularly projecting flanges provide this seat and shoulder with an increased width relative to the relatively narrow thickness of the plate-shaped main portion 12 of the bracket to ensure confident seating of the rail 104 atop the seat and against the shoulder. However, in other embodiments where the main portion 12 is sufficiently thick, out-turned seating and shoulder flanges may be unnecessary, as the perimeter edges of the main portion 12 itself may provide a sufficiently wide support seat and shoulder for contacting the bottom edge and face of the rail. Accordingly, the brackets need not necessary be formed by bent metal plates. In another embodiment, each bracket may be a plastic molded piece, whether having seating and shoulder flanges that project from a main post-abutting portion, or just relying on the thickness of this main post-abutting portion to provide a sufficient seat and shoulder width. Likewise, it will be appreciated that while the inner face of the main portion 12 is preferably flat in order to fit flush against the post, the outer face 26 need not necessarily be flat, and so the main portion may deviate from a purely planar configuration having flat opposing sides.
In the first embodiment, a seating depth of each bracket 10, 10a measured from the shoulder flange 18 to the bracing flange 14, thereby denoting the distance by which the rail 104 is seated from the bracing flange and the front outer side of the post during use of the bracket, equates to a half-width of the post minus a half-thickness of the rail, whereby the bracket is configured to center the rail across the lateral side of the post. So, a bracket designed for use on a 4×4 post (3.5-inch×3.5-inch inch finished size) with a 2×4 rail (1.5-inch×3.5-inch finished size) has a seating depth of ½×(3.5−1.5)=1-inch.
To allow optional use of differently sized rails, and more particularly rails of different edge-to-edge face width (which corresponds to the height of the rail in its installed face-out edge-up orientation), the shoulder of each third embodiment bracket 10″, 10A″ features two shoulder flanges 18A, 18B instead of a single shoulder flange spanning the full height from the seating flange 16 to the top end 20a of the bracket. A notch or slot 210 is cut into the inner edge vertical leg 120 of the blank 200″, as shown in
It will be appreciated that visually detectable indicators other than the terminal top end 20a of the bracket's vertical leg or a gap 19, break, notch or slot in the shoulder of the bracket may be used to set the height of the bracket at an appropriate relation to the top of the post for top-flush rail placement.
Finally,
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
