DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1-4, the present invention comprises a picket assembly 10 adapted for installation on a post of a barrier 14, such as a fence. The barrier 14 comprises a plurality of posts (of which only the corner post 12 is shown) preferably identical in construction, each of which is securely anchored at its base within a substrate (not shown), such as an underground mass of concrete. Each post extend along a rectilinear longitudinal axis, is tubular in construction, and is characterized by an open upper end, which is preferably closed by a cap. Preferably, each post is characterized by a rectangular transverse cross-section.

The posts are situated along the boundary of the area to be enclosed by the barrier 14, with a post spacing which is adequate to impart strength to the barrier 14 and to securely anchor other fence components. In one preferred embodiment, adjacent posts are separated by a distance no greater than 8 feet. The posts may be arranged in side-by-side relationship along two or more straight lines, two of which converge at a vertex, at which the corner post 12 is situated.

The barrier 14 further comprises a plurality of longitudinal rails 16, preferably of identical construction, which extend in transverse relationship to the posts. Each of the rails 16 extends between each adjacent pair of posts, including the corner post 12 and each of its adjacent line posts, and is supported by the posts at its opposite ends. The rails 16 are preferably configured into a rail assembly, such that at least two, and preferably three or more rails 16 extend between each adjacent pair of posts. The length of each rail 16 should be sufficient to fully span the distance between the adjacent of pair of posts 12 which will support that rail 16.

The rails 16 which extend between a given pair of posts are preferably disposed in parallel relationship. The incline of each rail 16 with respect to horizontal should substantially equal the incline of the terrain on which pair of posts supporting that rail 16 are installed. Thus, when the barrier 14 is positioned on horizontal terrain, the rails 16 will be disposed substantially horizontally.

With continued reference to FIGS. 1 and 2, the barrier 14 further comprises a plurality of elongate line pickets 18, preferably of identical construction, each of which extends in transverse relationship to the vertically spaced rails 16. Each line picket 18 is secured to each of the spaced rails 16. Preferably, the line picket 18 extends through an opening 20 formed in the upper surface of each rail 16, and is secured internally within the rail 16 by a retaining rod extending through the line picket, as described in U.S. Pat. No. 5,443,244. Alternately, the line picket may be secured externally to the rail 16 by a fastener, such as a bolt, or secured internally within the rail by welding. The base of each line picket 18 is preferably situated no more than a small distance above the terrain supporting the barrier 14, in order to prevent an intruder from traversing the gap between the base of the line picket 18 and the terrain.

The vertical height of each line picket 18 is preferably at least as great as the vertical height of the posts. The line pickets 18 are preferably oriented in parallel relationship, with a separation distance between adjacent line pickets 18, and between each post and its adjacent line picket 18, which is sufficiently small to prevent an intruder from traversing the gap. In one preferred embodiment, the separation distance between the centers of adjacent line pickets 18, and between each post and its adjacent line picket 18, is no more than 6 inches. Between adjacent pairs of posts, line pickets 18 should be provided in sufficient number to assure that the separation distance adjacent line pickets 18, or between a post and an adjacent line picket 18, does not exceed the requisite distance.

Each of the line pickets 18 is characterized an upper portion 22 and a rectilinear lower portion 24. In an installed position, the upper portion 22 of each line picket 18 is situated above the uppermost rail 16 of the barrier 14, while the lower portion 24 is situated between the uppermost and lowermost rails 16. Preferably, the upper portion 22 is characterized by curved profile, as shown in FIG. 1, with the curve extending toward the exterior of the barrier 14 and presenting a concave surface to the terrain. The projecting concave surface configuration of the upper portions 22 of the line picket 18 is well adapted to deterring an intruder attempting to climb over the barrier 14. Further deterrence of climbing may be effected by forming the end of the upper portion 22 into a pointed or sharpened configuration, such as a spear or spike.

The components of the barrier 14, including posts, rails 16 and line pickets 18, are preferably formed from a strong and durable material, such as steel, and may be configured into the requisite shape by roll forming.

With reference to FIGS. 1-5, the picket assembly 10 comprises at least one post picket 26 having an upper portion 28 and a lower portion 30, with the lower portion 30 characterized by a rectilinear profile, as best shown in FIGS. 3 and 4. Preferably, the picket assembly 10 comprises at least two, and more preferably three post pickets 26. The post pickets 26 comprising the picket assembly 10 are preferably of identical shape and construction, and preferably are formed from the same materials as the line pickets 18. The upper portion 28 of each of the post pickets 26 is preferably characterized by a profile conforming to that of the upper portion 22 of the line pickets 18. In the embodiment shown in the Figures, the upper portion 28 of each post picket 26 is characterized by a curved profile. The lower portions 30 of the post pickets 26 are preferably characterized by a length substantially less than that of the lower portions 24 of the line pickets 18. An acceptable length for the lower portion 30 of is between about 6 inches and about 18 inches.

The picket assembly 10 further comprises a post closure 32 which functions to hold the post pickets 26 and close the hollow upper end of the corner post 12. Components of the post closure 32 are preferably formed from the same materials as the corner post 12 and line posts. The post closure 32 comprises a cap 34, best shown in FIGS. 6 and 7, having an inner surface 36 and an outer surface 38. The cap 34 is preferably identical in size and construction as the caps used on the line posts. The cap 34 is hollow and its base should have a transverse cross-sectional profile which matches that of the corner post 12, so that the cap 34 can closely fit around the upper end of the corner post 12, and thereby close it. One or more fastener openings (not shown) may be provided in the cap 34 in order to secure the cap 34 to the corner post 12. Alternatively, cap 34 may be secured to corner 12 post by welding or some other binding technique.

At least one, and preferably a plurality of recesses 40 are formed in the cap 34, in a number equal to the number of post pickets in the picket assembly 10. Thus, in the embodiment shown in the Figures, which features a picket assembly 10 formed from three post pickets 26, three recesses 40 are provided in the cap 34. Each recess 34 is sized to closely, but clearingly, receive the lower portion 30 of a post picket 26 therethrough, as shown in FIGS. 3 and 4.

When plural recesses 40 are provided, the recesses 40 are preferably joined into a unitary opening 42, as shown in FIG. 5. If such a joined opening 42 is provided, each individual recess 40 should retain a sufficient portion of its borders cap 34 with so that the recess 40 remains capable of guiding and positioning a post picket 26. Alternately separate discrete recesses may be provided. The recesses 40 (and opening 42, if any) are preferably formed with a punch after the cap 34 has been manufactured.

The recess or recesses 34 should be positioned so that the post picket or pickets 26, when installed in the cap 34, form an effective barrier within the region above corner post 12, with no disproportionately large gap existing between adjacent post pickets 26, or between a post picket 26 and its adjacent line picket 18. As best shown in FIGS. 2 and 6, the recesses 40 are arranged such that the installed post pickets 26 are disposed in a symmetrical arrangement, with substantially equal included angles between each adjacent pair of post pickets 66, and with the distance between the upper ends of each adjacent pair of post pickets 26 either equal or approximately equal.

As shown in FIGS. 3, 4, 5, 8 and 9, the post closure 32 further comprises a bracket 44 which extends from the lower surface 44 of cap 34. The bracket 44 is characterized by an upper end 46 and an opposed lower end 48, with an end-to-end length of between about 6 and about 12 inches. The upper end 46 of bracket 44 is shaped to conform to the contour of the inner surface 36 of cap 34, and is permanently secured to the inner surface 36 of cap 34, preferably by welding. Two welds 50 are shown in FIG. 5.

The bracket 44 is characterized by a transverse cross-sectional profile, best shown in FIGS. 5 and 9, that provides an attachment surface 52 that can bracingly engage the lower portion 30 of each post picket 26 when that post picket 26 is received through a recess 40 of the cap 34. The post picket 26 is secured to its attachment surface 52 on bracket 44, preferably by fasteners (not shown), such as tek screws. Alternative binding techniques, such as welding, may also be used. As shown in FIGS. 3 and 4, when the lower portion 30 of a post picket 26 is secured to bracket 44, its upper portion 28 extends uprightly from a position adjacent the outer surface 38 of cap 34.

As shown in FIG. 1, the bracket 44 should be sized so that it is clearingly receivable within the open upper end of the corner post 12. A gap 54 should exist between each side 56 of bracket 44, so that the tubular walls of corner post 42 may engage the inner surface 36 of cap 34 without obstruction. The bracket 44 should be positioned such that it traverses the cap 34 at an area of maximal width. Thus, if the base of cap 34 is characterized by a rectangular cross-section, the bracket 44 should extend along a diagonal thereof. If the base of cap 34 is characterized by a circular cross-section, the bracket 44 should extend along a diameter thereof.

The components of the picket assembly may be advantageously provided in the form of a kit, comprising a post closure, a sufficient number of post pickets to fill the recesses of the post closure cap and a sufficient number of fasteners to secure the post pickets to the post closure bracket. The fasteners should be provided in a number greater than or equal to the number of corner pickets. The kit further comprise the fasteners (if any) that are needed to secure the cap to a corner post.

Once assembled, the picket assembly 10 is installed by inserting bracket 44 into the upper end of corner post 12, and securing cap 34 to the corner post 12, with fasteners or otherwise. The installed picket assembly 10 serves to increase the security provided by barrier 14, by securely filling a gap that would otherwise exist in the area immediately above corner post 12. At the same time, the picket assembly 10 provides an aesthetically satisfying appearance that conforms to that presented by the line pickets 18 of the barrier 14.

While the present invention has been described with reference to a corner post, it should be understood that it may also be installed on a line post as well. In this eventuality, it may be preferable to use only a single post picket, and to position the recess and bracket of the post closure so that the post picket extends toward the exterior of the barrier.

Changes may be made in the construction, operation and arrangement of the various parts, elements, steps and procedures described herein without departing from the spirit and scope of the invention as defined in the following claims.
