The present invention relates generally to rackable fencing and, more particularly, to rackable fencing comprising components that have been optimized for shipping unassembled from a manufacturing location to an assembly location.
Good fences make good neighbors. Better fences, however, should achieve more.
The terrain across which a fence may be desired often is not level but rather is inclined. Accounting for such topography may require expensive and time consuming custom fence fabrication on-site. It is more desirable, however, for fencing for such a project to be purchased pre-assembled, yet adaptable for adjustment to match inclined terrain, as pre-assembly would simplify installation and would reduce costs as a result of economies of scale. Even more desirably, such pre-assembled fencing might be adjustable to match a range of inclines, as a range of inclines may be encountered even upon a single fencing installation and certainly between several fencing sites.
Modularity of pre-assembled fencing panels is also desirable. Inasmuch as plans may be altered during installation of fencing, or additional fencing may be discovered to be desirable after installation of an initial run, or later replacement may be desired of a section of fencing damaged after installation, modularity of design would allow easy and aesthetically matching and consistent final results.
The modern economy is described as “global” and in such a context it would be desirable to provide a fence design with components that may be manufactured at a first location, better suited for manufacturing, and shipped unassembled to a second location, better suited for assembly, at which second location the components should be of a design that they are easily connected into finished fencing panels for sale thereafter to end users or for distribution to retailers. In such a context, recognizing the need to minimize the shipping costs, it would be desirable for a fencing design to comprise a minimal number of components that had been optimized so as to be most densely packed into shipping containers. Ideally, those same components should at the same time be of a design allowing efficient connectivity at the assembly location, preferably requiring use only of simple and inexpensive tools, and, once assembled, complement the structural function of each other.
For fencing that is to be manufactured at a first location and shipped unassembled to a second location for assembly, it would be desirable for the components to be designed such that they could be fully painted, coated, or otherwise surface-treated at the manufacturing site yet later assembled at a possibly distant assembly site without damage to the finished surface from transport or from assembly. As to shipping, such fencing components should have no exposed and/or delicate features that would be susceptible to damage in transit, which is inefficient and costly to repair distant from a manufacturing location. Once delivered to the assembly location for assembly, such fencing should comprise a minimal number of different components, for simplification of assembly. And, ideally, only simple, inexpensive tools would be required for such assembly. Once assembled and ready for sale to end users, connectors and structural details ought to be concealed from view, for aesthetic appeal.
Finally, for fencing designed to be manufactured at a first location and shipped unassembled for assembly at a second location into finished fencing product, it would be desirable for the design of the fencing components and the finished assembly to be such that the finished assembly is sturdy, structurally sound, tight, and without loose parts.
The fencing products previously known do not ideally address the foregoing objectives.
A rackable fencing comprising components that have been optimized for pre-assembly shipping is disclosed. As revealed in the following description and the appended figures, this invention discovers a clever and efficient design that achieves the described objectives and more.
In accordance with certain aspects of certain embodiments of the present technology, a rackable fence is provided that comprises a rail, a picket carrier, and a plurality of pickets. The rail may define a rigid inverted U-shaped cross-section and a longitudinal axis. The picket carrier may include a top span that resides within and extends across the inverted U-shaped cross-section. Each of the pickets may be pivotally attached to the picket carrier and pivotable toward the rail
First and second shoulders may be disposed within the bottom of the inverted U-shaped cross-section and located opposite one another. The picket carrier may reside above the first and second shoulders. In certain embodiments, each pivotal attachment of each picket to a picket carrier may be at a screw, a bolt, a pin, a rivet, or a spring-loaded keeper.
The picket carriers may be metal, extruded plastic, or injection molded plastic.
In certain embodiments, the inverted U-shaped cross-section may be symmetrical.
In some configurations, the rail, the first shoulder, and the second shoulder may be integral.
In accordance with yet additional aspects of other embodiments of the present technology, a rackable fence is provided that may include a first and second rail, a first and second picket carrier, and a plurality of pickets. The first and second rail may each have a header, a first wall extending downwardly from one side of the header, and a second wall extending downwardly from the other side of the header. The header, first wall, and second wall may be rigid one-to-another. The first wall may carry a first shoulder that is disposed toward the second wall and the second wall may carry a second shoulder that is disposed toward the first wall, with both the first and second shoulders disposed opposite the header. The first and second picket carriers may each include a plurality of apertures defined top-to-bottom through each such carrier, with a span across the top of each carrier between such apertures. The first and second picket carriers may be carried upon and above the first and second shoulders that may be, in turn, carried by the first and second walls, respectively. Each picket may be attached to the first and second picket carriers at the apertures and configured to be pivotable toward the first rail.
In certain embodiments, the header, and the first and second shoulders may be integral. In particular configurations, the header, first and second walls, and first and second shoulders may be roll formed and, in some instances, roll formed from a single width of material.
The first and second shoulders may define between them a first width and the first and second picket carriers may each define a cross-sectional width, such cross-sectional width being greater than the defined first width. In particular configurations of the present technology, the first and second rails may define a first symmetrical cross-section. In some aspects, the first and second picket carriers may each define a second symmetrical cross-section.
In accordance with aspects of other embodiments of the present technology, a rackable fence may be provided with a first and second rail, first and second picket carriers, and a plurality of pickets. The first and second rails may each define a length and have a header, a first wall that depends downwardly from the header, and a second wall that depends downwardly from the first header and that is opposite the first wall. The header may be disposed above the first and second walls and, together with the first wall and second wall, define a channel between them. The first and second picket carriers may each be in contact with a first and second wall of a respective rail. Further, each such picket carrier may define a cross-section, the cross-section being open downwardly. Each such picket carrier may carry a plurality of pivots, the pivots being disposed normal to the length defined by the rails at the location of each such pivot. The first and second picket carriers and the pivots may reside within a channel of one of the rails. Each of the pickets may be attached to the first and the second picket carriers by the pivots. The first rail may be movable along its length relative to the second rail.
In accordance some embodiments of the present technology, the header, the first wall, and the second wall may be rigid relative to each other. In particular configurations, the first wall may carry a first shoulder that is opposite the header and the second wall may carry a second shoulder that is opposite the header, with the first picket carrier being carried by the first and second shoulders.
In accordance with yet still further aspects of other embodiments of the present technology, the first and second picket carriers may each include a top span, a first and second profile that both extend downwardly from the top span, a first flange extending outwardly from the first profile, and a second flange extending outwardly from the second profile. In some arrangements, the first flange may be carried upon the first shoulder of the first wall of a rail and the second flange may be carried upon the second shoulder of the second wall.
In accordance with yet still further aspects of other embodiments of the present technology, the top span, first profile, second profile, first flange, and second flange may be integral.
In certain embodiments, the first and second picket carriers may each define symmetrical cross-sections. Also, the header, the first wall, and the second wall may be integral.
So configured, a fence is disclosed with components that may be manufactured at a first location and shipped unassembled to a second location for assembling. A minimal number of different components are required. The components may be fully painted, coated, or otherwise surface-treated at the manufacturing site yet later assembled at a second site without damage to the finished surface from transport or from assembly, as they have no exposed or delicate features that are susceptible to damage in transit. The components may be densely packed into shipping containers, yet thereafter easily connected into finished fencing panels with efficient connectivity requiring use only of simple and inexpensive tools. Once assembled and ready for sale to end users, the fence's components complement the structural function of each other and the finished assembly is sturdy, structurally sound, tight, and without loose parts, and connectors and structural details are concealed from view.
