1. Field of the Invention
The present application relates to fences of the type incorporating well known stakes or posts commonly referred to as “pickets.” Although such pickets generally have a pointed upper end, the term “picket” as used herein is intended to mean all types of such stakes, including pointed, rounded, square ended pickets or and the like.
The present invention relates to fencing construction utilizing vertical rectangular pickets (or any other round, rectangular, elliptical or other shaped material), which pickets are assembled or connected to, into or through, one or more hollow members running perpendicular or at other angles to the pickets.
While the invention has merit when used to assemble materials other than plastic (e.g., PVC), it has particular advantage in the manufacture and assembly of plastic fencing, and in particular, plastic fencing which must have similar aesthetics when viewed from either side (two sided fencing).
In particular, the invention relates to a new and unique method for assembling such fencing which method offers strength, beauty, ease and flexibility of construction and installation not heretofore available.
2. Description of the Related Art
Originally, all fencing was made of wood. As the cost of wood increased, and the constant painting and limited life span of wooden fences became burdensome, an industry evolved utilizing plastic substitutes for wood.
Unfortunately these fences until now have had either visual or structural deficiencies, and 10 especially those of the ‘two sided’ nature.
Two sided plastic fences constructed to date utilize a hollow top horizontal plastic rail (such as a 2″×4″ or other shape or size) with top and bottom slots cut into it so that pickets maybe inserted through. There are presently several methods of securing the pickets.
One method is to screw the pickets to the rails. Another is to drill through both and insert a pin. A third method generally utilizes a larger bottom rail (generally 2″×6″ or 2″×8″) with slots cut only into the top of the rail which permits entry of the picket to the point where it rests on the bottom portion of the rail, requiring the rail to support the picket. With this method, which is most commonly used, without additional unsightly fasteners the pickets may not protrude below the bottom rail, an aesthetic feature which is often desired by consumers. The picket itself has a locking crimp at the bottom which permanently snaps into the rail, so that it can not be removed without damaging the material. Partially because of the weight of the pickets, a larger bottom rail is used because the fencing otherwise will have a tendency to warp or bow downwardly in the middle. A steel or aluminum brace is sometimes inserted in the bottom rail to minimize the bowing that occurs.
All other presently existing two sided designs encase the pickets between two horizontal members, utilizing either visible screws, nuts and bolts, brackets, etc. or clips, caps, clamps or crimps or other such unsightly and less durable materials.
While a variety of two sided plastic fences are available, utilizing various methods of assembly, none of these offer the method of manufacture and assembly provided by the invention. Nor do they offer the resultant flexibility, strength, durability, beauty and ease of assembly, all of which combines to make a more economical to produce product which at the same time offers higher quality and a type not heretofore available entirely in plastic.
A fence assembly is disclosed which comprises at least one post member, at least one picket member fixedly positioned in adjacent relation to the post member, and an elongated support member extending between the post member and the picket member to support the picket member in predetermined fixed relation to the post member. The elongated support member extends through at least a portion of the picket member, or entirely therethrough, to support the picket member without need for an external rail member.
In one embodiment a fence assembly is disclosed which comprises, at least one post member, at least one rail member associated with and adjacent to the post member and oriented at an angle relative to the post member, at least one picket member oriented at an angle relative to the rail member, and an elongated support member extending between the post member and the picket member to support the picket member in predetermined fixed relation to the post member and the rail member.
In the preferred embodiment, a fence assembly is disclosed which comprises, at least one post member, at least one rail member attached to the post member and oriented at an angle relative to the post member, at least one picket member oriented at an angle relative to the rail member, and an elongated support member extending between the post member and the picket member to support the picket member in predetermined fixed relation to the post member and the rail member.
The post member is generally upright and the rail member is generally transverse relative to the post member, and the elongated support member in the form of a bar which extends at least partially into the picket member to support the picket member in the fixed position, the support member being of sufficient strength to support a plurality of such picket members while increasing the strength and rigidity of the fence assembly. The picket members are constructed of a relatively lightweight material, and the support member is constructed of a material of strength greater than the strength of the picket members, the support member extending through each picket member. The relatively lightweight material of the picket members is plastic, and the material of the support member is at least one of metal, plastic and wood. The post member defines at least one aperture for receiving and supporting the rail member, and the rail member defines at least one aperture for receiving and supporting the picket member, the picket member defining an aperture for reception of the elongated support bar such that the elongated support bar supports the picket member in the fixed relation to the rail member and the post member.
In a preferred embodiment, the support member has a generally rectangular cross-sectional configuration. In another embodiment the elongated support member has a channel-like cross-sectional configuration. In still another embodiment the elongated support member is positioned within an aperture formed in a face of the picket member, the support member being associated with the rail member. The support member may be formed integral with the rail member and it may have a generally T-shaped cross-sectional configuration and be supported within the rail member.
The support member may have a generally L-shaped cross-sectional configuration and be supported by the rail member in integral relationship therewith.
The support member may also be uniformly molded with the rail member so as to be monolithic therewith.
The support member may also be monolithically molded with the rail member.
The rail member may be oriented generally perpendicular to the post member, or it may also be oriented at a generally acute angle to the post member.
In another embodiment the elongated support member has a generally channel-like configuration on one side an on the opposite side the elongated support member has a channel-like member of width less than the first side, the last mentioned channel-like member being configured and dimensioned to receive a support member attached to each picket member to support the picket members. The support member may be attached to each picket member by a tab formed as part of the picket member.
The elongated support member may have a cross-sectional configuration having a first member and second and third members extending generally perpendicular from the first member, the second and third members extending in relatively opposite directions.
The elongated support member may comprise at least one member having at least two members extending generally perpendicular from one face, and at least a single member extending in a direction generally opposite the first mentioned member and generally perpendicular to the first mentioned member. Preferably a plurality of such post members, a plurality of such rail members, and a plurality of such picket members are respectively assembled to form the fence assembly.
A method is disclosed for assembling a fence, comprising, positioning at least one post member in generally upright orientation, positioning at least one rail member adjacent to the post member at an angle relative thereto, positioning at least one picket member relative to the rail member, and connecting at least one elongated support member between the post member and the picket member in a manner to support the picket member in predetermined fixed relation to the post member and the rail member and to provide strength to the assembly of the post member, rail member and picket member. The members are preferably plastic, and a plurality of such members is generally provided.
The present invention is a marvel of simplicity as it relates to a fence assembly and method of assembling same. It eliminates the need for any screws, nuts and bolts, brackets, clips, caps or other such unsightly and less durable materials. It further permits the replacement if needed of pickets or rails without damaging other components.
Equally important, the insertion of a bar or shape through each picket dramatically increases the strength and rigidity of the assembled product, virtually eliminating the ‘sagging’ and bowing of the rails in a fashion dramatically superior to any method currently in use, while at the same time allowing for greater lengths to be used between posts.
Assembly of the fence is unique and simple. Each picket has holes cut into each side. A plastic and/or metal (or any material) bar simply slides through each picket, locking the picket in place without the need for any other method of fastening.
The size of the hole on the bottom portion of the rail, which hold is generally located directly below the top hole may be extended lengthwise (for example, approximately ½″ longer than the top hole on one end 0 or two)). One advantage of the invention is that the usage of the bar, combined with the extended bottom hole on the rails, allows the assembled fence section to self adjust for landscape that is not horizontal, with the pickets remaining vertical. Depending on the length of extension of the bottom hole in each rail, installation on slopes varying from level (for example, onto a sloping surface of 20 degrees or so) is achievable. Larger slopes can be accommodated by making a slightly larger cut on the upper hole as well. Of course if a desired appearance is to have the pickets slope with the terrain, this is inherent in the invention's design as well.
Moreover, the rail can be eliminated and the strengthening bar can act as a rail as well. Further, although the rail may be physically attached to the post, physical attachment is not necessary since “attachment” can mean simply inserting the rail into an aperture in the post to fix their relative positions. Further, in its broadest sense, the invention relates to a fence assembly in which the rail is eliminated and the support and strengthening bar can act as a rail as well as a picket support and strengthening factor.
It will be seen from the description which follows that various rail/support and strengthening bar configurations and arrangements can be incorporated into a fence system without departing from the true scope of the invention.
Preferred embodiments are described hereinbelow with reference to the drawings, wherein:

As can be seen by referring to

In addition, it can be seen that the pickets 20 no longer need to rest on a lower rail but can be suspended from the upper rail by virtue of the support of the bar 30 as well as the relative rigidity to the entire structure which is imparted thereto by such bar 30.
Alternatively shaped lengths of material may be slid through the hollow rails (as opposed to the bars which slide through the pickets) which would also accomplish both level and sloping installations, and which would also allow the pickets to slide through the rails, and still lock in place at a predetermined location, and would also help diminish or eliminate the bowing of the rails.
One such shape would be an extruded material of a modified “U” shape, which would be used as a stiffener. This stiffener would be substituted for the bar 30 described hereinabove in the first described embodiment. This stiffener would have two horizontal ledges, one above the other facing downward from the bottom of the “U”, with a space between the ledges, running the length of the stiffener. This “U”-shaped stiffener would be slid into the rail rotated 90 degrees so that the horizontal bottom of the “U” becomes vertical.
The stiffener is slid in with the ledges facing the center and the front edge and rear edge of the “U” touching one vertical wall of the rail. It shall occupy a space less than one half the width of the rail interior. The amount less than one half of the rail's interior is determined by measuring ½ of the picket's width. This measurement would then be subtracted from the horizontal (i.e., side to side) dimension of the stiffener. When the picket is slid down vertically through the rail, it shall then be pressing against the horizontal running ledges of the stiffener.
Each picket, instead of having slots on each side for the bar to slide through as described in the first embodiment, shall alternatively have a crimp or multiple crimps made in it of a size and at a point measured to fit between the ledges of the bar, so as to lock the pickets in place vertically. Another alternative method of fastening (instead of the bar or the crimp) is to have a hole cut into either the picket, the “U”-shaped bar, or both, and to insert a device into the hole which would retract so the picket could be slid through the openings in the rail, and pop out or spring out or otherwise protrude when reaching the ledges.
All of the above beyond the first described embodiment, and variations of them are also unique and new. For the most part they can accomplish much of the same goals as the method described in the embodiment of
Several shapes other than a “U” shape could be utilized. One such example would be an “L” shape. Among the important and novel advantages to all of these shapes is that they allow a picket to slide through all the rails, and to lock into the rails at a predetermined stop position through the placement of crimps, or of holes with a locking device inserted into the holes to make with a stop position designed either into the bar, or the picket, or both, while at the same time imparting strength to the assembly not envisioned or available with the present art.

It can be seen that given a certain degree of flexibility and resilience in bar 48, picket 52 having horizontal transverse groove 54 is simply inserted into opening 56 and made to engage and flex the bar 48 until the bar 48 snaps into groove 54 to support the picket 50 in the same manner as disclosed in the previous embodiments. Although not shown to scale, the groove 54 can be of sufficient thickness to receive the bar 48 in snug fashion so as only to permit shift upward and downward movement of picket 52 when being supported by bar 48 on a fence system.

While the fence assembly of the present invention has been described generally with reference to one example post member, one example rail member, one example picket member, and one example elongated support member (or support and strengthening bar) it should be readily understood that respective pluralities of such major components are contemplated to form most completed fence assemblies according to the invention.
Further, as can be seen from the description and drawings herein, although the post members are generally upright in most assemblies, it is contemplated that the post members, the rail members and the picket members can be assembled in a variety of orientations, being at right angles or acute angles relative to each other to form a fence assembly which accommodates any terrain, according to the present invention.
Additionally, while the rail members can be physically attached to the post members by fasteners or the like, it is only necessary to attach the rail members to the post members by fixing their position relative to the post members, as by mere insertion into an aperture in the post member, or by indirect attachment to the post member, as by attaching the rail member to another device such as a bracket, which in turn is attached to the post member. In fact as noted previously, the rail members can be eliminated, and the elongated support member can be configured and structured to function as a rail member as well as a picket support and strengthening member. One example of such structure can be seen in
Moreover, it should be understood that although the components of the present invention are preferably made of a suitable extrudable or moldable plastic, specifically PVC and its co-polymers and other polymers and polymer blends known in the art, metals such as aluminum or the like may also be utilized to form the fence system. In addition, combinations of materials may be used. For example the support bar may be made of an extrudable plastic and the pickets may be made of a metal material or vice a versa. Various combinations can be envisioned by those skilled in the art.
