The invention will be better understood and objects of the invention will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
The method of manufacturing an artificial branch 10 includes providing a main stem assembly 20, a plurality of branch stem members 30, a plurality of short limb assemblies 40, a plurality of long limb assemblies 45, a plurality of limb connector members 50, a longitudinal support member 70, a plurality of foliage members 60, a limb end assembly 52, and a reinforcing plug member 25. The specific quantities of each of the items provided is dependent, at least in part, upon the specific physical configuration of the artificial branch 10 to be manufactured.
The main stem assembly 20, branch stem members 30, short 40 and long limb assemblies 45, and limb end assembly 52 may be made from acrylonitrile butadiene styrene, polyvinyl chloride, polybenzimidazole, polyethylene, fiberglass wrapped acrylonitrile butadiene styrene, fiberglass wrapped polyvinyl chloride, fiberglass wrapped polybenzimidazole, fiberglass wrapped polyethylene, low density polyethylene, high density polyethylene, or a combination thereof. Preferably, high density polyethylene is used.
As an initial step, the reinforcing plug member 25 is typically inserted to a bore 21 of the main stem member 20 adjacent to a first end 22 of the main stem member 20. It should be noted, that the main stem member 20 may be manufactured and provided with a reinforcing plug 25 integrally formed into the main stem member 20. Additionally, depending upon the configuration desired, the main stem member 20 may be cut to a desired length. Optionally, the reinforcing plug member 25 may be welded into the first end 22 of the main stem member 20.
The reinforcing plug member 25, when installed into the main stem member 20 provides additional structural support for mounting the assembled artificial branch 10 to a vertical structure.
A longitudinal support member 70 may be inserted into the main stem member 20 adjacent to a second end 24 of the main stem member 20. The present invention contemplated both configurations in which the second end 24 of the main stem member 20 is cored to accept the longitudinal support member 70, as well as those in which the second end 24 of the main stem member 20 is formed with an aperture providing an interference fit with the longitudinal support member 70.
A first branch stem member 30 is positioned over the longitudinal support member 70 and may operationally couple a first end 32 of the first branch stem member 30 to the second end 34 of the main stem assembly 20.
A first limb connector member 50 is positioned over the longitudinal support member 70 and operationally couples a first end 54 of the first limb connector member 50 to a second end 34 of the first branch stem member 30. The first limb connector member 50 has at least one side coupling portion 58. The limb connector members 50 may have a profile which is substantially cruciform, positions one or multiple side coupling portions 58 at an angular relationship compared to a plane defined by the first end 54 and the second end 56. The angle of each side coupling portion 58 does not have to be uniform, symmetrical, or parallel.
Depending upon the specific physical configuration desired either at least one short limb assembly 40 or at least one long limb assembly 50 is selected and then operationally coupled to the at least one side coupling portion 58.
A second branch stem member 30 is positioned over the longitudinal support member 70 and operationally couples a first end of the second branch stem member to a second end of the first limb connector member 50.
A second limb connector member 50 is positioned over the longitudinal support member 70 and operationally couples a first end of the second limb connector member 50 to a second end of the second branch stem member 30.
Again, depending upon the specific physical configuration desired, a second at least one short limb assembly 40 or at least one long limb assembly 50 is selected and then operationally coupled to a side coupling portion 58 of the second limb connector member 50.
The steps of positioning a branch stem member, positioning a limb connector member, selecting at least one short limb assembly or at least one long limb assembly, and operationally coupling the branch stem member, limb connector member, and selected limb assembly are repeated as necessary until the desired branch configuration is achieved
The limb end assembly 52 is positioned onto a second end of the longitudinal support member 70.
The plurality of foliage members 60 is then operationally coupled onto the plurality of short limb assemblies 40 and long limb assemblies 45.
While the foliage members 60 are typically colored and formed to resemble pine needles, the foliage members may include foliage, ghillie strips, lights, tarps, banners and other similar items used to provide camouflage or a desired aesthetic. Not every foliage member 60 on a given system 10 needs to be the same type or identical within the type of materials.
In at least one embodiment, each one of the branch stem members has a bore extending therethrough. The bore has a bore first end and a bore second end. Each one the branch stem members having a first end and a second end. The second end preferably has a cross-section diameter smaller than a cross-section diameter of the first end, and the bore first end has a bore cross-section slightly larger than the branch stem member second end cross-section such that the branch stem member second end may be inserted into a bore first end of a second branch stem member.
In a further embodiment, each one of the first limb connector member has a connector bore extending therethrough. The connector bore has a cross-section diameter approximately equivalent to the bore cross-section such that a branch stem member second end may be inserted through the connector bore.
In still a further embodiment, each one of the side coupling portions of the limb connector members have a cross-section diameter approximately equivalent to the branch stem member second end cross-section diameter.
In a preferred embodiment, the branch stem second end, the bore first end cross-section, connector bore, and the side coupling portions have a geometric cross-section which inhibits rotation. Illustrative examples of cross-section shapes which inhibit rotation include, but are not limited to square, triangle, cross, pentagon, hexagon, octagon, and similar shapes.
In a preferred embodiment, the method also includes the steps of welding each joint formed by an operational coupling between a main stem member and branch stem member, branch stem member and branch stem member, branch stem member and limb connector member, limb connector member to limb connector member, limb connector member to short limb assembly, limb connector member to long limb assembly, or branch stem member to limb end assembly.
In a further embodiment, the steps of providing a plurality of short limb assemblies and providing a plurality of long limb assemblies further includes the steps of: (a) providing a plurality of main limb members; (b) providing a plurality of limb tip members; (c) determining a length of limb assembly to be provided; (d) operationally coupling a limb tip member to a first main limb member; (e) operationally coupling a second main limb member to said first main limb member if desired; (f) operationally coupling a subsequent main limb member to the second main limb member if desired; (g) drilling a plurality of foliage attachment bores into selected main limb members and the limb tip member if desired; and (h) welding each joint formed by an operational coupling between main limb members or between a main limb member and the limb tip member.
In at least one embodiment foliage attachment bores are drilled into the short limb assemblies and long limb assemblies for facilitating the attachment of foliage members.
In a preferred embodiment, each of the joints formed between branch stem members, limb assemblies, limb connector members, limb end assemblies, and the main stem assembly are welded.
In at least one embodiment, the system 10 is able to withstand winds of up to one hundred miles per hour for at least ten minutes without breakage of the main stem assembly 20, limb connector members 50, Long and Short Limb Assemblies 45,40, and Branch Stem Assemblies 30.
In a more preferred embodiment, the system 10 is able to withstand winds of up to 150 miles per hour for at least ten minutes without breakage of the main stem assembly 20, limb connector members 50, Long and Short Limb Assemblies 45,40, and Branch Stem Assemblies 30.
In another preferred embodiment, each of the main stem assembly 20, branch stem members 30, short limb assemblies 40, long limb assemblies 45, limb connector members 50, and foliage members 60 are effectively transparent to RF radiation so as to not provide significant loss for an RF signal transmitted from or received by an antenna coupled to the base structure 2.
Again, those skilled in the art may readily appreciate that the present invention encompasses embodiments where the various members are textured, colored, or both to provide additionally concealment or camouflage. An illustrative example, and not for purposes of limitation may be to have the various members colored and textured to resemble a specific type of tree or bush.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
