Description




The present invention is directed to a bracket for coupling a pair of rail members, and more particularly, to a bracket for adjustably coupling a fence post and a fence rail.




BACKGROUND OF THE INVENTION




Ornamental fences are widely used for security and aesthetic purposes. However, professional fence installers are often required to install an ornamental fence, and their relatively high hourly rates significantly contribute to the final cost of the fence. Accordingly, it is desired to minimize the time required to install a fence, or to enable a homeowner to install a fence himself or herself, thereby eliminating payments to the fence installer.




In particular, improvements in the forming of structural connections when installing fences are needed to increase the ease of installation. For example, existing methods for attaching a fence rail to a fence post often require the field drilling of holes and passing fasteners through the holes, or aligning pre-drilled or pre-welded joints. These operations usually require extensive use of tools and can be time consuming. Furthermore, the use of pre-drilled or pre-welded components reduces the flexibility to account for any variations or out-of-range tolerances in the fence components. Accordingly, there is a need for an attachment bracket for attaching a fence rail to a fence post in a fast, efficient and adjustable manner.




When installing a fence on a hill or uneven terrain, the fence must be angled to match the inclination angle. An inclined fence is typically either rigidly prefabricated to match the incline, or is constructed with a series of hinged connections that allow the fence to pivot within a predefined range to match the ground angle. The former method requires precise measurements and minimizes any flexibility in the fence to allow for fine adjustments. The latter method typically incorporates a series of simple pin connections to give the fence its flexing ability. However, the pin connections often do not easily rotate, and may bind during attempted rotation. Furthermore, the pins extend outwardly from the fence, and provide a surface upon which clothing or other items may catch. Finally, the exposed pin heads are unsightly and subject to rust. Accordingly, there is a need for a connector for coupling various fence components which allows easy, unimpeded rotation of the fence components, and which remains generally hidden from view.




In order to securely anchor a fence post into the ground, a hole is typically dug in the ground, the fence post is set in the hole, the post is leveled and adjusted, and the hole is filled with concrete to encase the post. However, such an operation usually requires two separate contractors: one contractor to dig the hole and pour the concrete (the concrete contractor), and another contractor to precisely locate, adjust and fix the fence post locations (the fence installer). This division of labor is necessitated by union rules, as well as varying skills of the laborers. Such an arrangement requires both contractors to work together at the same time, and causes difficulties in scheduling, contractor availability, on-site space constraints, and requires one contractor's progress to depend upon the other's progress. Alternately, the concrete contractor may set the fence posts in the poured concrete without assistance from the fence installer. Once the concrete has set, the fence installer may mount the various fence components to the fence post. However, this method limits the fence installer's ability to adjust the location of the posts, and the fence installer must use various methods to fit the fence components to existing post locations. Accordingly, there is a need for a foundation for receiving a fence post and a method of installing a fence post which enables the concrete contractor to pour the foundation independently of the fence installer's locating and fixing of the fence posts.




SUMMARY OF THE INVENTION




The present invention is a bracket for coupling a fence rail to a fence post that enables the position of the rail to be adjusted relative the post, and is also quick and easy to install. The bracket can slide along the fence rail, which enables the position and effective length of the rail to be adjusted relative to the post.




In particular, the present invention is a bracket for coupling a first member to a second member having an opening for receiving the first member. The bracket is generally “U” shaped and has a first leg and a second leg such when the legs are spaced apart the first leg engages the first member and the second leg engages the second member to couple the first and second members together. The bracket is preferably sized to fit within the rail.




The present invention is also directed to a spool for coupling a fence picket to a fence rail. The spool is received in the rail, and the picket is passed through an opening in the spool. In this manner, the picket is coupled to the rail for rotation. The spool is recessed in the rail, easy to install, and guides the picket rotation in a smooth manner.




In particular, the present invention is a spool for coupling a fence picket to a support member, the spool comprising a generally cylindrical body having an opening generally perpendicular to the longitudinal axis of the cylindrical body. The picket may be passed through the cylindrical body at the opening, and the spool is sized to fit within the support member to guide rotation between the picket and the support member.




The present invention is also foundation for receiving a fence post and a method of installing a fence post that enables the foundation to be poured separately from the installation of the fence post. That is, the concrete contractors may dig the required holes and fill them with concrete. The fence installers may then appear at their convenience to install the fence posts securely into the foundations poured by the concrete contractors. This enables the concrete contractors to work independently of the fence installers, while still providing the fence installer the ability to locate the fence posts. The resultant fence post/foundation combination is relatively strong and durable.




In one embodiment the invention is a reinforcing member for strengthening a foundation for a fence post, the reinforcing member being shaped to fit into a hole that is to be filled with concrete to form the foundation having an upper section for receiving the fence post. The reinforcing member comprises an upper portion for strengthening the concrete at the upper section of the foundation, and a lower portion that rests on the bottom of the hole and supports the upper portion.




Other objects and advantages of the present invention will become apparent from the following description, the accompanying drawings and the appended claims.

DETAILED DESCRIPTION




As shown in

FIG. 1

, a typical fence


10


comprises a plurality of generally vertically extending posts


12


that are anchored into the ground. However, it is to be understood that the invention may be used with a variety of fences, and the fence


10


of

FIG. 1

is only one type of fence that may be used with the invention. Each post


12


has a base


14


that is received in a reinforcement


16


. The fence


10


also includes a plurality of vertically extending, spaced pickets


18


, and a plurality of generally horizontally extending rails


20


(including top rail


20


′) extending between each post


12


. As shown in

FIG. 7

, a typical rail


20


has a top panel


22


, two side panels


24


, and an open channel


26


formed therein. Each rail


20


has a pair of open ends


28


(

FIG. 2

) and a plurality of laterally extending holes


30


formed therein, through which a picket


18


may be passed. The top rail


20


′ may lack the holes


30


formed in its top panel


22


, as the pickets


18


need not pass through the top rail


20


′. Each rail typically includes a pair of inwardly extending flanges


29


extending from the side rails


24


. As shown in

FIGS. 3 and 9

, each post


12


preferably includes a cutout


32


shaped to receive a rail


20


therein, and the cutout


32


defines a flange


34


protruding generally upwardly into the cutout


32


.




The bracket


36


of the present invention is shown in detail in

FIGS. 4-5

, and may be used to couple a rail


20


to a post


12


. The bracket


36


is generally U-shaped and includes a first leg


38


and a second leg


40


. The second leg


40


has a hole


42


formed therein to receive a threaded fastener


44


(FIG.


5


). The second leg


40


also includes a notch


46


shaped to fit over the flange


34


in a cutout


32


in a fence post


12


. The bracket


36


has a head


51


that includes an upper portion


53


and a lower portion


57


. The bracket


36


is preferably formed from a corrosion-resistant material, such as aluminum, although a variety of other materials may be used, such as stainless steel or other metals, plastics, compounds, and treated wood.




In order to couple a rail


20


to a post


12


, the bracket


36


is slid down the open end


28


of a rail


20


(or rail


20


′) into the open channel


26


. The rail


20


is then slid into the cutout


32


in the post


12


, as shown in FIG.


10


. The rail


20


may be inserted into the post


12


at any desired depth; that is, the rail


20


may extend into the interior


48


of the post


12


as far as desired. This is accomplished by sliding the bracket


36


within the channel


26


to the desired position. Once the rail


20


is located as desired, the bracket


36


is urged into the interior


48


of the post


12


until the notch


46


fits over the flange


34


of the post


12


. In some cases, the ramp


50


on the front side of the second leg


40


rides up along the flange


34


until the flange


34


snaps in place in the notch


46


.




Once the bracket


36


is properly positioned and the flange


34


is received in the notch


46


, a threaded fastener


44


is passed through the hole


42


in the second leg


40


. The fastener


44


is preferably a socket head cap screw, but other types of fasteners may be used. The fastener


44


is rotated until the end


52


of the fastener engages the first leg


38


. Continued rotation of the fastener


44


forces the first leg


38


and the second leg


40


apart, and the rotation continues until the bracket


36


is sufficiently locked in place. At this point, the bracket


36


is held in place due to the frictional engagement between the first leg


38


and underside of the top panel


22


of the rail


20


, and the engagement of the flange


34


and notch


46


. Furthermore, a third point of contact is preferably provided by the upper portion


53


of the head


51


engaging the underside of the top panel


22


of the rail


20


, or by the lower portion


57


of the head


51


engaging the flanges


29


of the rail


20


. The engagement of the head


51


with the rail


20


provides a third point of contact that helps to stabilize the bracket


36


in the rail


20


.




In certain situation, particularly when using relatively small rails, the second leg


40


of the bracket


36


is preferably sized so as to fit between the opening


31


between the two flanges


29


(FIG.


7


). It may be necessary for the second leg


40


to fit between the flanges


29


so that the second leg leg


40


can extend downwardly enough to engage the flange


34


. In this case, the width of the second leg


40


may be reduced so enable it to fit through the opening


31


. However, the head


51


preferably remains wider than the opening


31


to prevent the bracket


36


from falling through the opening


31


, and to provide a surface that can bear upon the flanges


29


when the bracket is in the locking position.




As best shown in

FIG. 10

, the hole


42


for receiving a fastener


44


forms a slight angle A with a vertical plane. The angle A allows a tool (not shown) that is used to tighten the fastener to diverge from the post


12


. This divergence provides the necessary spacing between the tool and the post


12


to allow the tool to be operated; i.e. in a hand operated tool, this allows the operator to fit his or her hand between the tool and the post


12


when grasping the tool. It is to be understood that other means beyond those described specifically herein may be used for spreading the legs, such as the use of a spring


33


or other biasing member.




Once properly mounted, the bracket


36


secures the rail


20


and post


12


together. The bracket


36


can also pivot to accommodate an angle formed between rail


20


and the post


12


, such as shown in FIG.


12


. The bracket


36


of the present invention may be used with a top rail


20


′ as well as the other rails


20


in the fence. The bracket


36


may be used to couple a rail


20


to any body that has an appropriate opening to receive the bracket


36


and that has a flange to fit into the groove


46


in the bracket


36


. For example, the bracket


36


may be used to couple a rail


20


to a wall that has an opening formed therein.




As shown in

FIG. 11

, a fence


10


must often be mounted on a hill or incline. When matched to the angle of incline, each rail


20


forms an angle with the posts


12


and pickets


18


. The fence


10


shown in

FIG. 11

incorporates a spool


54


at each intersection of a rail


20


and a picket


18


to guide the relative rotation between the rails


20


and pickets


18


. The spool


54


ensures smooth rotation, which allows the rails


20


and pickets


18


to assume a variety of angles without binding during rotation. The spool


54


of the present invention is shown in

FIGS. 13-15

, and includes a generally cylindrical body


56


having an opening


58


generally perpendicular to the longitudinal axis of the cylindrical body


56


. The opening


58


is shaped to allow a picket


18


(

FIG. 8

) to pass through the opening


58


. The generally cylindrical body


56


may include a pair of flats


55


. The spool


54


is also sized to be received within the open channel


26


in a rail


20


(FIG.


16


). In order to properly mount the spool


54


in a rail


20


, the spool


54


is slid into the channel


26


at an end


28


of the rail


20


such that the ends


60


of the spool


54


are against the side panels


24


of the rail


20


. The spool


54


is moved down the length of the rail


20


until its opening


58


is aligned with the holes


30


formed in the rail


20


. The picket


18


is then passed through the holes


30


in the rail


20


(

FIG. 2

) and the opening


58


in the spool


54


(FIG.


16


). The pickets


18


are then preferably fixed to the spools


54


by welding, bonding, or other attachment methods to secure the pickets


18


in the fence. Once the picket


18


is passed through the spool


54


, the picket


18


may be rotated relative the rail


20


, and the spool


54


guides the relative rotation. As shown in

FIG. 12

, a spool


54


may be mounted at each rail/picket interface to guide the rotation, including the intersections of the pickets


48


and the top rail


20


′. Once the posts


12


, pickets


18


and fence rails


20


are mounted as shown in

FIG. 12

, the rails


20


may be rotated relative the pickets


18


as guided by the spools


54


. Furthermore, because each spool


54


is recessed inside a rail


20


, it is generally hidden from view, which provides a uniform outer surface and does not provide a surface upon which clothing may catch. The spool


54


is preferably formed from a corrosion-resistant material, such as aluminum, although a variety of other materials may be used, such as stainless steel or other metals, plastics, ceramics, compounds, and treated wood.




The fence posts


12


, as shown in

FIG. 1

, are mounted in a foundation


16


that is typically formed of concrete. The foundation


16


provides a base into which the posts may be securely mounted. To form the foundation


16


of the present invention, a hole


60


is first dug in the ground and a reinforcing member, or wire cage


62


, is set into the hole


60


as shown in FIG.


18


. The reinforcing member


62


includes a lower portion


64


and an upper portion


66


that is shaped to receive a form


68


therein. The reinforcing member


62


is generally annular in the illustrated embodiment, and has two or more vertically extending legs


70


, as well as a plurality of rings


72


connected to the legs. The reinforcing member


62


is preferably made of steel bars, or woven wire mesh, but any other suitable material may be used, including but not limited to metal, plastics or wood. The lower portion


64


is sized to locate the upper portion


66


at about ground level when the reinforcing member


62


is placed in the hole


60


.




Once the reinforcing member


62


is inserted into the hole


60


, the form


68


is inserted into the top portion


66


of the reinforcing member


62


. The form


68


may be nearly any acceptable material, such as wood, and is preferably of a larger size than the base


14


of the fence post


12


that is to be mounted in the foundation


16


. Once the reinforcing member


62


and form


68


are properly located, the hole


60


is filled with concrete


69


to the top of the form


68


or until the hole


60


is sufficiently filled (FIG.


19


). Once the concrete


69


has sufficiently set up, the form


68


is removed, leaving a post socket


76


in the foundation


16


. The concrete contractors may then leave the site. Once the concrete


69


is sufficiently cured, the fence contractors may mount the fence posts


12


into the foundation


16


, as will be described below.




The posts


12


are mounted into the foundation


16


by placing the post


12


into the post socket


76


. Because the post socket


76


is larger than the base


14


of the posts


12


, the post


12


may be adjusted within the post socket


76


to the desired location (FIG.


20


). The socket


76


may be larger than the post base


14


so as to allow the post base to be adjusted in one or more directions only (i.e. the socket


76


is in the form of one or more slots), but the socket


76


is preferably larger than the post base


14


in all directions to provide maximum flexibility. This flexibility in the lateral positioning of the posts


12


allows the installer to account for variations in dimensions of the various fence components. Once the post


12


is in the desired location, it is held in place while the post socket


76


is filled with grout


80


, concrete, plaster, mortar, cement, or other similar setting agents. Union rules allow a fence contractor to pour grout in these quantities, although they are generally not permitted to pour the concrete that forms the foundation


16


. Once the grout


80


in the socket


76


is set up, installation of the fence post


12


is then completed. The rings


72


in the reinforcing member provide support around the post base


14


and upper section


82


of the foundation


16


. This support helps to keep the grout


80


and post


12


securely in place, and reduces chances of the post


12


being shaken loose by impact, wear or weather conditions. Grout may not, by itself, normally be strong enough to hold the fence post


12


in place. However, the grout


80


, in combination with the concrete


69


and top portion


66


of the reinforcing member


62


, are strong enough to sufficiently anchor the fence post


12


. Once the grout is cured, the remaining fence components may be mounted to the posts


12


.




The upper portion


66


of the reinforcing member may assume a variety of shapes beyond those discussed herein. For example, the “rings”


72


may be square, triangular, or other shapes in top view. Furthermore, the rings


72


may be replaced or supplemented with nearly any shape or arrangement of bar members that connect one or more of the leg members


70


. The upper portion


66


, in any case, should be shaped to reinforce and strengthen the upper section


82


of the foundation


16


, and to receive a form


68


during pouring of the foundation. Furthermore, the lower portion


64


of the reinforcing member


62


may assume a variety of shapes beyond those discussed herein. The lower portion


64


need only locate the upper portion


66


at the desired elevation, and may do so by resting in the bottom of the post hole


60


and supporting the upper portion


66


at about ground level.




While the forms of the apparatus described herein constitute a preferred embodiment of the invention, the present invention is not limited to the precise forms described herein, and changes may be made therein without departing from the scope of the invention.
