DETAILED DESCRIPTION OF THE DRAWINGS
[0045] Referring to
[0046] As depicted, in embodiments, the upper and lower rail members 112, 114 each can extend between an upper and lower rail member proximal end 122a, 122b and an upper and lower rail member distal end 124a, 124b, with the proximal end 122a, 122b being defined as the end farthest away from the connection loop 118 and with the distal end 124a, 124b being defined as the end which is closest. At the proximal ends 122a, 122b, upper and lower rail members 112, 114 can be removably coupled to the upper and lower center support rods 108, 109, which are arranged substantially perpendicular to rail members 112, 114. Additionally, at distal ends 124a, 124b, the upper and lower rail members 112, 114 can further comprise at least one bore hole (not shown) that is configured to receive a fastener to secure the upper and lower rail members 112, 114 to connection loop 118.
[0047] Although the free stall system 100 disclosed herein is described as a single free stall system, it should be noted that system 100 may vary in embodiments. For example, as shown in
[0048] In embodiments, referring now to
[0049] Next, the upper and lower rail members 112, 114 and connection loop 118 can be pre-assembled prior to installation, or may be assembled onsite during installation of system 100, thereby forming the first and second dividers 104, 106 of the free stall units 102. During installation, the first and second dividers 104, 106 are positioned substantially parallel to each other, with the connection loop 118 facing outwardly and away from the center support rods 108, 109. As shown in
[0050] To form the free stall system 100, each of the upper and lower rail members 112, 114 can be initially washed and ground prior to installation utilizing a specific grinding technique in which an abrasive is employed. In some aspects, the abrasive has a grit size in a range of about 30 to about 100 grit, in other aspects about 40 to about 90 grit, in other aspects about 50 to about 85 grit, and in certain other aspects about 60 to about 80 grit. Once the grinding process is complete, the rail members 112, 114 can be coated with an ultraviolet coating to increase the wear life of the rail members, as well as to prevent the formation of slivers and corrosion caused by environmental conditions and exposure to substances such as urine or feces. Similarly, to prevent decreased wear and corrosion of connection loop 118, connection loop 118 can be coated with a zinc or similar material plating during the fabrication process.
[0051] Referring to
[0052] As illustrated in
[0053] In other embodiments, although not shown, a cutting station can be arranged at a back end of system 300 and can comprise a means for cutting a coated fiberglass material. In some embodiments, system 300 can comprise a single front end cutting station 302, while in other embodiments, system 300 may comprise two are more cutting stations. For example, in certain aspects, system 300 may comprise a first cutting station that is configured to size the initial fiberglass apparatus 350 to a first length (e.g., 90 feet), whereas a second cutting station may arranged to size the fiberglass apparatus 350 to a shorter length such as, e.g., 50 feet or less. In some aspects, the first cutting station may sever one end of the initial fiberglass apparatus 350 while the second cutting station may sever the opposite end of the initial fiberglass apparatus 350. In some aspects, system 300 utilizes a first cutting station 302 on one end of the fiberglass apparatus 350 and a second cutting station 302 on the opposite end of the fiberglass apparatus 350. In some aspects, the first and second cutting stations 302 cut the fiberglass apparatus 350 in sequence. In some other aspects, the first and second cutting stations 302 cut the fiberglass apparatus 350 at about the same time. In still some other aspects, the first cutting station 302 cuts a first fiberglass apparatus 350 and then a second fiberglass apparatus 350 before a second cutting station 302 cuts the opposite end of the first fiberglass apparatus 350. In other words, the first and second cutting stations 302 may be spaced apart during the processing line, such that one or more different fiberglass apparatus 350 are cut by the first cutting station 302 before the opposite end is cut by a second cutting station 302. In still some further aspects, a single cutting station 302 may cut a first end of the fiberglass apparatus 350 and then the same cutting station 302 used to cut the fiberglass apparatus 350 to a desired length, two or more desired lengths, and/or to remove a second end of the fiberglass apparatus 350.
[0054] In some aspects, the initial fiberglass apparatus 350 is a reclaimed, recycled and/or reused fiberglass rod or fiberglass tube commonly used in the oil industry. In some other aspects, the initial fiberglass apparatus 350 is a fiberglass component reclaimed and/or reused from a different industry. In yet some other aspects, the initial fiberglass apparatus 350 is a new fiberglass component. The term “fiberglass apparatus” should be understood herein to refer to a solid fiberglass rod, a fiberglass tube, or other elongated structure that is substantially comprised of fiberglass, which may have the same or differing diameter over the length of the structure. The holding station 304 is arranged proximate the cutting station 302 and includes a holding frame 340 for holding each severed fiberglass apparatus 350. The holding frame 340 can comprise a plurality of transverse bars 342 attached to a longitudinal bar 344. In addition, the holding frame 340 can comprise a plurality of protruding posts 346, which may be equidistantly spaced apart from one another and positioned so as to form a stop mechanism that prevents the plurality of fiberglass apparatus 350 from sliding off an edge of the holding frame 340. Posts 346 are rotatable about a rotation axis and can comprise a generally L-shaped or other suitable configuration in certain embodments. Notably, the configuration of posts 346 is such that each post is rotatable between a first postion and a second positon to allow for the release of the fiberglass apparatus 350 from the holding frame 340 and into a conveyor assembly 306 as the next apparatus 350 is ready for processing to ensure continuous run cycles.
[0055] Referring now to
[0056] Once the fiberglass apparatus 350 is placed on the conveyor assembly 306, the fiberglass apparatus 350 can be continuously spun and rotated as it undergoes the surface preparation process (i.e., the pre-wash, grinding and coating process) prior to reaching drying station 316. Particularly, during the surface preparation process, each fiberglass apparatus 350 is self fed into the grinder station 310 to roughen the outer surface of the fiberglass apparatus 350 to produce a surface profile that is suitable for coating. For example, prior to the grinding process, the surfaces of the fiberglass apparatus 350 can generally be dirty, greasy, shiny, glassy, or fuzzy, thereby making it difficult for coatings to adhere to the surface. In embodiments, the grinder station 310 can optionally comprise a washer 318 mounted adjacent a double sided grinding apparatus 320 that is used to prewash the outer surface of apparatus 350. The double sided grinding apparatus 320 can comprise a first and second grinder wheel 321, 323 arranged on opposing sides of the fiberglass apparatus 350. Each grinder wheel 321, 323 can comprise a diamond grit ranging in size from about 30 grit to 120 grit in various embodiments depending upon the desired surface finish (e.g., coarse or fine) and the type of coating to be applied. In many applications of the present invention, because a ultra-violet (UV)resistant coating is applied to each of the fiberglass apparatuses, it is advantageous to use an abrasive with a grit size of about 70-90 grit, with 80 grit being preferable in certain aspects. In addition, to help ensure continuous rotation of the fiberglass apparatus 350 as it is fed through the grinder station 310, the double sided grinding apparatus 318 can comprise at least two grinder rollers 324.
[0057] Upon being washed and ground, the fiberglass appartus 350 exits the grinder station 310 and can be exposed to compressed air 329 and a dryer 328 to remove any residual water or solvent from the fiberglass appartus 350 and be dried prior to the coating station 310.
[0058] As the fiberglass apparatus 350 is conveyed from the grinder station 310 into the coating station 312, which is arranged proximate an outlet 325 of the grinder station 310, a coating is applied to prevent and minimize corrosion of apparatus 350. Coating station 312 can comprise a plurality of coating guide rollers 332 and a spray nozzle 334 pivotally mounted to a sprayer arm 336 to ensure uniform application of the coating solution to the fiberglass apparatus 350. For example, as the rod is continuously rotated, one or more coating layers are applied to ensure homogeneous application of the coatings to the rod. In embodiments, various coating techniques may be utilized such as, for example, liquid or powder coating techniques. In certain aspects, the liquid or powder coatings may comprise a UV-resistant coating material that additionally helps to protect the fiberglass apparatus 350 from environmental effects such as extreme sun exposure. In some aspects, the coating comprises a UV-resistant material to prevent and minimize corrosion and sunlight damage. In some aspects, the coating station 312 may comprise two or more spray nozzles 334, such that more than one coating of the same material or different materials may be applied to the fiberglass apparatus 350. In some aspects, a first primer coating may be applied by a first spray nozzle 334 prior to a second UV-resistant coating being applied by a second spray nozzle 334. In other aspects, a drier may be employed between the first spray nozzle 334 and the second spray nozzle 334 to help dry to the coating prior to a second coating being applied.
[0059] In some embodiments, system 300 can further comprise a transfer assembly 314 having a first and second transfer arm 360, 362, each movable between a first and second position as shown in
[0060] During each of the pre-wash, grinding, coating and transferring positions, the rotation of the fiberglass apparatus 350 may be variable depending upon the size of the fiberglass apparatus. In some aspects, the fiberglass apparatus 350 is rotated such between about 0.001 of an inch to about 0.005 of an inch of fiberglass material is removed, in some other aspects between 0.001 of an inch up to about 0.05 of an inch, in some other aspects up to about 0.3125 of an inch of fiberglass are removed as the elongated fiberglass apparatus 350 passes through the grinding station.
[0061] Drying station 316 can comprise at least two horizontal holding beams 370 each comprising a plurality of drying clamps 372 arranged atop of the holding beams 370 and being sized to accommodate a portion of the fiberglass apparatus 350. In one embodiment, the fiberglass apparatus 350 can be cured (i.e., dried) utilizing conventional drying techniques such as, e.g., air drying. In other embodiments, various curing technologies such as UV curing, hot air curing, infrared curing, electrical curing or others can be employed to accelerate and to reduce drying times. In still other embodiments, system 300 may comprise two or more drying stations with
[0062] In other optional embodiments, although not depicted, system 300 can further comprise a second cutting station arranged adjacent drying station 316 that additionally reduces the size of each fiberglass apparatus 350 from the initial sizing performed at cutting station 302 (e.g., from about 90 feet to 36 feet). Once the apparatus is severed and sized accordingly, the fiberglass apparatus 350 may be fed through a bundler (not shown) where, in one embodiment, the fiberglass apparatuses 350 are bundled in bulk units. In certain aspects, the number of units can comprise between 10 to 100 units. It should be noted, however, that in other embodiments, the fiberglass apparatus 350 may be bundled in fewer or more units.
[0063] Once the fiberglass apparatus 350 is cured, it may be used in various applications. For example, in one embodiment, the fiberglass apparatus 350 can be installed to form a gate. In other aspects, the fiberglass apparatus 350 can be installed in an electrical fencing system 400 for used for livestock, such as in a horse pasture (see
[0064] In other exemplary embodiments, such as system 250 illustrated in
[0065] In yet another embodiment, the fiberglass apparatus may be used to form free stalls as previously discussed.
[0066] In addition, rail members can be connected by using various connectors. Referring to
[0067] In some aspects, the ID of the connector piece 500 is between about ½ inch to about 12 inches, in some aspects about ¾ inch to about 8 inches, in some aspects about 1 inch to about 6 inches, and in some other aspects about 1¼ inches to about 3 inches, although one of ordinary skill in the art will appreciate that ranges and subranges within the foregoing ranges are contemplated. In some aspects the OD of the connector piece 500 is between about ¾ inch to about 12¼ inches, in some aspects about 1 inch to about 8 inches, in some aspects about 2 inches to about 6 inches, and in some other aspects about 2¼ inches to about 3 inches, although one of ordinary skill in the art will appreciate that ranges and subranges within the foregoing ranges are contemplated. In some aspects, the difference between the ID and the OD of the connector piece is between about ⅛ inch to about 1 inch, in some aspects between about ¼ inch and about ¾ inch, and in some other aspects between about ¼ inch and about ⅝ inch. In some aspects, the W of the connector piece 100 is between about ¼ inch and about 3 inches, in some aspects between about ½ inch and about 2½ inches, and in some other aspects between about 1 inch and 2 inches.
[0068] Referring to
[0069] Also as shown in this embodiment, threaded fastener assembly 503 comprises a threaded fastener 502, such as a socket set screw of a type that is commonly used in the threaded fastener industry, and a threaded nut 504 that operably engages the threaded fastener 502. In this aspect, the threaded fastener 502 of the threaded fastener assembly 503 may be longer than when the threaded fastener 502 is used to secure the connector piece 500 to rail 510. In this embodiment, threaded fastener 503 is inserted in threaded hole 501 (not visible) with a sufficient amount of thread engagement to hold it in position upon connector piece 500, and threaded nut 504 is installed upon threaded fastener 503. In this embodiment threaded nut 504 is of a type that is commonly used in the threaded fastener industry, however it may be of any design, size, and material of construction that enables it to make thread engagement with threaded fastener 503. In this embodiment, threaded nut 504 may be engaged with threaded fastener 503 by assembling connector piece 500, threaded fastener 503, and threaded nut 504 to create a residual static tensile stress in the threaded assembly that is sufficient to prevent movement of the connector piece 500, threaded fastener 503, and threaded nut 504 relative to each other. Methods of assembling threaded fasteners are known to those who have ordinary skill in the art. In this embodiment threaded nut 504 provides a secondary purpose of creating a spacing between the outer surface of connector piece 500 and the outer surface of a second connector piece 500 when the swivel connector assembly is completed. In other embodiments where it is not necessary or desirable to use a threaded fastener for the purpose of creating a spacing between the connector pieces 500, any other type of mechanical spacer may be used, for example, a mechanical washer that is manufactured from any suitable material. In other embodiments where it is not necessary or desirable to use a threaded nut 504 or any other type of mechanical spacer between the connector pieces 500, said threaded nut 504 or other mechanical spacer may be omitted from the swivel connector assembly while still allowing proper functioning of the swivel connector assembly by connection between the first and second connector pieces using a threaded fastener 502 or 503.
