DETAILED DESCRIPTION OF THE INVENTION
(26) Many aspects of the invention can be better understood with the references made to the drawings below. The components in the drawings are not necessarily drawn to scale. Instead, emphasis is placed upon clearly illustrating the components of the present invention. Moreover, like reference numerals designate corresponding parts through the several views in the drawings.
(27) In one contemplated embodiment of the current invention, a single clip allows for extreme racking of a significant angle to the ground. Until now, such extreme racking was achieved by most of the prior art only through the use of extra wide stamping of existing stringers. The single clip according to the current invention also eliminates rattle and is more cost effective.

(29) By way of introducing the subject matter of this description, it is very easy to build fences on flat ground. A contractor merely needs to buy enough fence panels to lay out a straight line of fence to do the job. In many circumstances, however, a fence must traverse an incline, or be racked. To achieve this, the pickets must extend up and through the stringer rails in a non-perpendicular fashion; in other words, the pickets must extend at an angle of less than or more than 90 degrees through the rail. When a fence is racked, such as when it traverses an incline, the pickets are angled relative to rails. However, the angling of the pickets relative to the rail requires a larger punched hole in the web of the rail. Smaller punched holes in the web of the rail are preferable. The smaller holes are more aesthetically pleasing and result in greater stability of the rail and overall fence.
(30) While the prior art has several means by which this can be accomplished, the means often require external attachments, unsightly holes, and a rattling between the rails and the pickets due to loose connections. The current invention solves these problems by using the clip to create constant pressure between the pickets and rails, thereby allowing for effective racking of a fence without the rattling associated with most of the prior art.
(31) FIGS. 1 through 4 are a series of drawings of the actual clip, showing its different parts. FIG. 1 is a front view of the clip, generally referenced as 1. The clip 1 has a top edge 6, a bottom edge 7, two side edges 8, and is roughly rectangular in shape, although embodiments with rounded edges are contemplated as well. The clip is made in this embodiment of sheet metal that is laser cut although other methods of manufacture are contemplated. In this embodiment, laser lines are cut such that the clip 1 is separated into several sub-regions: the T-Keeper, which is then bent up and serves to anchor the clip into the pivot, two bent edges 4, which are bent up and provide a constant force between the rail and the picket, and the base 3, which is the rest of the clip. The T-Keeper has a wide head portion, and a narrow neck portion. The wider head portion will later anchor the T-Keeper into a slot after the clip is turned sideways. The bent edges can be inclined at a variety of angles off the plane of the clip. In a particular embodiment, the bent edges are inclined at between 20 degrees and 45 degrees, inclusive, off the main body of the T-Keeper clip. In a further embodiment, the bent edges are inclined at between 25 degrees and 30 degrees. In another embodiment, the bent edges are inclined at 27.3 degrees.
(32) FIGS. 5 through 7 contain three drawings showing the clip attached to a picket, and the clip applying pressure internally against the inside of a rail. In FIG. 5, the picket 10 has had a notch, or picket slot cut 12 put into it at a location where a rail is going to be placed. It should be noted that making a relatively small picket slot cut into the picket is much less damaging to the overall strength of the fence panel than some of the prior art methods which involved larger removals of picket metal and/or drilling holes for screws, bolts, etc. The clip and method of using it also provides a substantial savings in terms of cost and time, as a large number of pickets can be lined up on the ground or a table to have the picket slot cut put into them at the same part of the picket. Many of the prior art attempts to solve this problem require individual holes to be drilled in each picket, which is much more time-consuming and costly in terms of human hours required to assemble the fence panel.
(33) FIG. 7 shows the clip after having being inserted into the pocket slot cut on the picket 10 and turned 90 degrees so that the T-Keeper (not visible in this figure) has turned sideways and has locked the clip in place. FIG. 7 is a cross sectional view that shows the picket 10 after a rail 11 has been attached. The rail as a rail hole 14 in its top surface through which the picket is inserted. The rail has two sides 13 with outer and inner surfaces. The clip is retained in the picket slot cut by the T-Keeper 2. The bent edges 4 of the clip apply pressure against the inner surface of the raid side 13, keeping a constant pressure (in the direction shown by 15) between the picket and the rail. Because the ends of the bent edges 4 are flat, the resulting pressure is a plane from the ends of the two bent edges pushing against the flat plane of the inner wall of the rail. This allows the picket and rail to pivot around each other in two planes 21 and 22, and prevents the rattling sound that occurs when the picket and rail are not kept in place by constant pressure.
(34) FIGS. 8 through 10 are a series of drawings showing another view of how the rotation without rattling is accomplished. FIG. 8 is an exploded view of how the rail has a rail hole 14 hole through which the picket is pushed. The rail hole is slightly wider than the picket width 16 (it should be noted that many pickets are square, such that the picket width 16 is the same as the picket length 107). The size and shape of the rail hole allows for the picket to pivot and the picket pivoting through the rail hole establishes two parallel planes (21 and 22 in FIG. 10) which are kept parallel by both the size and shape of the rail hole and the pressure 24 that the clip places from the picket to the inside surface of the rail. The T-Keeper keeps the clip in place, and, as shown in FIG. 9, the rail is forced by the pressure created by the bent edges of the clip to move around a pivoting axis 20, limited only by the T-Keeper range of motion 23, in two parallel planes 21 and 22.
(35) FIGS. 8 through 10 are drawings also show how the rail has a hole through which the picket is pushed, and how the size and shape of the rail hole allows for the picket to pivot and how the picket pivoting through the rail hole establishes two parallel planes which are kept parallel by both the size and shape of the rail hole and the pressure that the clip places from the picket to the inside surface of the rail and how the rail is forced by the pressure created by the bent edges of the clip to move in two parallel planes.
(36) With the prior art, the pivoting axis was some place other than the top of the rail, which required a larger hole through which the picket could rotate. With the current invention, the pivoting axis is at the top of the rail, which allows for a small pivot hole to be cut, making for a sturdier and more attractive fence.
(37) FIGS. 11 through 14 are front views showing some prior prototypes of the clip, which are also considered to be part of this invention and are not intended to be limiting in any manner. Among the other versions of the clip are a rounded version (FIG. 11), a notched version (FIGS. 12A and 12B), and two versions with foldable edges (FIGS. 13 and 14).
(38) FIGS. 15 through 17 are front views showing how this invention allows a fence to be constructed on flat ground (FIG. 15) or on sloped ground where the fence is racked (FIGS. 16 and 17).
(39) FIGS. 18 through 20 are perspective views showing how the clip is inserted into the picket slot cut and rotated, thereby not only locking it into place, but also allowing the clip to move back and forth in the picket slot cut, thereby allowing for a smoother and more efficient racking of a fence panel. As can be seen, once the T-Keeper is inserted into the picket slot cut, it can be turned 90 degrees. Because the T-Keeper is much longer at its top than at the narrower neck, once it has been turned, the neck has a very long range of motion within the picket slot cut. Thus, once the clip has locked onto a rail, the rail can be rotated up or down and will carry the clip with it.
(40) The clip discussed herein may also be used with a rail that has no hole in its web. For example, a rail may be located at the top of the fence panel, wherein the pickets extend up to, but not through the rail. In such a configuration, the picket slot cut or picket slot punch is located near the end of the picket, such that the inserted clip restrains the top of the picket within the rail, but does not extend through the web of the rail.
(41) Some embodiments of the current disclosure provide for a clip that includes one or more dimples on its base. The dimples are rounded protrusions that extend away from the base of the clip. When the clip is mated with the picket, as discussed in more detail below, the dimples extend toward the picket and apply a force that pushes the clip away from the picket. Accordingly, the dimples extend away from the base in a direction opposite of the bent edges. This perpendicular pressure would push the clip away from the picket but for the head of the T-Keeper that provides an opposite restraining force. The dimples provide for a smooth installation and removal of the clip, if required, with little to no scratching of the coating or other surface of the picket.
(42) FIG. 21 is a cutaway side view of a clip, picket, and rail according to selected embodiments of the current disclosure. A picket 10 extends through a rail hole 14 in a rail 11. A clip 1 is secured through a picket slot cut 12 of the picket by a T-Keeper 2. A bent edge 4 is adjacent to and pushes against the side of the rail 11. A flap 5 of the base of the clip 1 includes a dimple 25. The dimple extends towards and pushes against the side of the picket 10. Thus, the clip 1 provides a force that pushes the inside of the rail 11 away from the outside of the picket 10.
(43) FIG. 22 is a back-elevation view of a clip with a dimple according to selected embodiments of the current disclosure. A clip 1 has a T-Keeper 2 that extends away from the base 3. A flap 5 between two bent edges 4 includes a dimple 25. The dimple 25 has a length that is greater than its width. Particular embodiments provide for a dimple that is at least twice the length of its width. Other embodiments provide for a dimple that is at least four times its width. The length of the dimple extends between the two bent edges 4.
(44) The dimple or embossment of the clip creates a holding pressure between the clip and the picket. The dimple pushes the body of the clip away from the picket, while the T-Keeper provides an opposite force that pulls the clip towards the picket, thereby increasing rigidity and reducing, if not eliminating, rattling. As shown in FIG. 21, the dimple also displaces the surface of the clip base away from the picket to prevent damages to the powder coat during both installation and use. The smooth transition of the dimple avoids sharp edges that may come in contact with the picket. The picket movement is against the dimple as opposed to the entire base, thereby minimizing the surface area in contact between the two components, which results in less friction and smoother movement when the two components are rotated or moved relative to each other. Furthermore, the dimple is positioned close enough to the top of the clip such that any damage to the picket caused by contact between the dimple and the picket is hidden once the clip is secured to the picket and within the rail.
(45) In other embodiments, the two bent edges 4 are instead one or more dimples. The dimples are rounded protrusions that extend away from the base of the clip. Like the bent edges, the dimples provide a constant force between the rail and the picket.
(46) FIG. 23A, FIG. 23B, and FIG. 23C show the rackability of a picket using a clip in a rail according to selected embodiments of the current disclosure. FIG. 23A shows a picket 10 passing through a rail 11 at approximately a ninety-degree angle; in other words, perpendicularly. The picket 10 includes a picket slot cut 12 through which extends the T-Keeper of the clip 1. The clip 1 is shown centered about the centerline of the opening in the rail 11, as well as in the center of the picket slot cut 12. FIG. 23B shows a picket 10 passing through the rail 11 at an angle. The picket 10 includes a picket slot cut 12 through which extends the T-Keeper of the clip 1. The clip 1 is shown centered about the center line of the opening in the rail. However, the T-Keeper is off-center from the centerline of the picket. FIG. 23C shows a picket 10 passing through the rail 11 at a greater angle than that shown in FIG. 23B. The picket 10 includes a picket slot cut 12 through which extends the T-Keeper of the clip 1. The clip 1 is shown off-center from the center line of the opening in the rail. Additionally, the T-Keeper is off-center from the centerline of the picket. Thus, these figures show how the clip may slide and rotate relative to the picket within the picket slot cut, as well as how the clip may slide within the rail. The travel of the clip along the length of the rail allows the pivot point of the picket to shift. These features provide for a fence panel that racks to a significant angle while at the same time providing for a rigid, rattle resistant frame.
(47) While the preferred embodiments of the invention are described in some detail herein, the present disclosure is made by way of example only and that variations and changes thereto are possible without departing from the subject matter coming within the scope of the following claims, and a reasonable equivalency thereof, which claims I regard as my invention.
