DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0035] Referring now to the drawings, one preferred embodiment of the animal feed trough (“feed trough” or “trough”) is shown at broad reference numeral 10, and includes a base 12 and body 14 including curved body covers 14A, 14B positioned on the base 12. The base 12 has a generally triangular configuration. The body covers 14A, 14B are enclosed on opposite ends by annular body end covers 16, 18 and a top opening 20 is enclosed by a lid cover 22 having lid end covers 24, 26. The body end covers 16, 18 include notches 16A, 18A that align with notches 24A, 26A in the lid end covers 24, 26. In accordance with one preferred embodiment of the invention the opening 20 extends the length of the body 14 and defines an arc of 50 degrees relative to the circular cross-sectional shape of the body 14.

[0036] The body covers 14A, 14B and lid cover 22 in accordance with one embodiment are natural bark. The feed trough 10 therefore presents a natural outward appearance of a fallen log—something a forest animal such as a deer would be familiar with and would likely find non-threatening.

[0037] Referring now to FIGS. 2 and 3, the principal structural elements of the feed trough 10 are illustrated and explained. The body covers 14A, 14B are mounted on a pair of side panels 32, 34 that are bolted or riveted to the base 12, as shown. End caps 36 and 38 are likewise preferably bolted or riveted to the side panels 32, 34 to form the interior capacity of the trough 10. The lid cover 22 is mounted onto and supported by a lid panel 40. Lid end caps 42, 44 are positioned in the ends of and support the end caps 36, 38. The lid end caps 42, 44 include notches 42A, 44A that align with notches 36A, 38A in the lid end covers 36, 38. The aligned notches 16A, 18A and notches 24A, 26A in the lid end covers 24, 26, and the aligned notches 42A, 44A and notches 36A, 38A in the lid end caps 36, 38 also align with each other, as shown in FIGS. 5 and 7, and provide hand holds for the user so that the trough 10 can be manually carried as necessary. As an option, the notches 42A, 44A can be opened through to the interior of the trough 10, in which case they will provide a more secure hand hold and provide air exchange between air in the trough 10 and the surrounding ambient air. In some embodiments, the animal feed trough described herein may be configured with a motor and a timer to open/close or dispense feed at a predetermined time. In some embodiments, the timer may be battery-powered.

[0038] While a wide variety of materials are suitable, according to one preferred embodiment of the animal feed trough 10, the base 12 and body end caps 36, 38 are UV-protected thermoformed ABS plastic. The side panels 32, 34, lid panel 40 and lid end caps 42, 44 are also thermoformed ABS plastic. In an additional preferred embodiment, the animal feed trough 10, the base 12, and body end caps 36 and 38 are polyurethane. An example polyurethane is ROTOTHANE 4570, a two-component structural urethane, however any suitable polyurethane may be used to form the animal feed trough 10 described herein. In some embodiments, the animal feed trough 10, the base 12, and body end caps 36 and 38 are formed via rotocasting or centrifugal casting. In some embodiments, the animal feed trough 10 and body end caps 36 and 38 are formed together via rotocasting. In some embodiments, the body end covers 16, 18 may be exterior grade plywood. As noted above, covers 14A, 14B and 22 are preferably natural bark. Preferably, the bark is subjected to a kilning process that stabilizes the bark and sets the bark in the correct curvature to match the curvature of the side panels 32, 34 and lid panel 40. The bark covers 14A, 14B and 22 are preferably not permanently mounted to the side panels 32, 34 and lid panel 40, and can be removed if desired and replaced with different bark or with some other surface treatment. The bark covers 14A, 14B and 22 may be attached by a weak adhesive, or mechanically attached by clips, latches, pins or other similar attachment devices. Artificial covers 14A, 14B and 22 may be formed to resemble bark, and may be thermoformed ABS plastic. In some embodiments, the animal feed trough 10, body end caps 36 and 38 end covers 16 and 18, covers 14A-14B and 22. In some embodiments, the animal feed trough described herein may be configured with a motor and a timer to open/close or dispense feed at a predetermined time. In some embodiments, the timer may be battery-powered.

[0039] As best shown in FIGS. 1, 2, 3, 7 and 9, the base 12 has a generally triangular shape that promotes gravitation flow of the grain. The side panels 32, 34 are mounted above a raised central ridge 48 that extends along the length of the base 12 and form feed slots 50 through which gravity-fed grain flows from the interior of the body 14. The base 12 has a series of downstream feed dishes 52 that capture and accumulate the grain that falls by gravity through the feed slots 50. As best shown in FIG. 4, molded in feed stops 54 will retard most of the grain from continuing down the feed dishes 52 onto the surrounding ground. The feed dishes 52 are wide and flat and therefore minimize choking or jamming of the grain as it feeds out of the trough 10, as is the case with many other gravity feeders that attempt to transport grain from a large bin through narrow tubes. The feed dishes 52 extend laterally along the length of the trough 10, promoting even flow of grain along the length of the trough 10 and permitting several animals to feed at the same time. Placement of the feed dishes 52 on both sides of the trough 10 further promotes even flow of grain along the length of the trough 10 and permits several animals to feed at the same time on opposite sides of the feeder 10. The feed dishes 52 are defined by raised ribs 56 which extend downwardly from the central ridge 48. As best shown in FIG. 7, the ribs 56 include notches 58 into which the side wall panels 32 and 34 are positioned. While the angle of declination of the feed dishes 52 may vary, in one preferred embodiment the angle of declination of the feed dishes 52 is 25 degrees, but may optionally be between 15 and 35 degrees. In some embodiments the base 12 further includes a flow adjuster to modulate the flow of grain into the feed dishes 52. In some embodiments, the flow adjuster is a mesh lining covering the opening. Additionally, or alternatively, the flow adjuster is a lip affixed to the inside edge of the side wall panels 32 and 34 configured to slow the flow of grain into the feed dishes 52.

[0040] As is shown in FIG. 6, body end caps 36, 38 (36 shown) and lid panel 40 overlap in order to provide resistance to entry of moisture from the surrounding environment into the interior of the trough 10. The lid panel 40 can be releasably attached to the pair of side panels 32, 34 by latches of numerous types, by a snap-fit latch or slide fit configuration between the lid panel 40 and the pair of side panels 32, 34. By way of example, FIG. 8 shows a snap-fit latch 46 mounted on lid end cap 44 that snaps over the top edge of the end cap 38 with a comparable structure on lid end cap 42.

[0041] FIG. 10 shows the components of the trough 10 in a nested position prior to assembly and suitable for shipment and storage. By nesting the components in the manner shown, the space that would otherwise exist in the assembled trough 10 is reduced by approximately 50 percent.

[0042] While size and capacity can substantially vary, in one preferred embodiment the feeder 10 has a length of 36 in. (91.4 cm); a height of 22.25 in. (56.5 cm); a width of 36 in. (91.4 cm), with a body 12 diameter of 22 in. (55.9 cm). Grain capacity may be approximately 250 lbs. (113 kg.) depending on the type of grain, moisture content and similar factors. In another preferred embodiment, the feeder 10 has a length of 34 in. (86.4 cm); a height of 22.25 in. (56.5 cm); a width of 36 in. (91.4 cm), with a body 12 diameter of 22 in. (55.9 cm). Grain capacity may be approximately 200 lbs. (90.7 kg.) depending on the type of grain, moisture content and similar factors.

[0043] An additional embodiment is illustrated in FIGS. 11 and 12. The animal feed trough 100 includes a body 114, a base 112, a cylindrical opening 105, and a lid 110.

[0044] The body 114 is defined by a hollow semi-cylindrical core 130 flanked by two end caps 136 forming an interior for storing grain. The hollow semi-cylindrical core 130 of the body 114 includes a cylindrical opening 105 for adding grain to the interior of the body 114. The cylindrical opening may further include a lid 110 to keep the grain protected from moisture. In some embodiments, the lid 110 screws into the cylindrical opening 105. Additionally, the lid 110 may snap into the cylindrical opening 105. In some embodiments, the lid 110 is a Gamma Seal Lid®.

[0045] The hollow semi-cylindrical core 130 may be comprised of a thermoplastic such as ABS or polyurethane. In some embodiments, the hollow semi-cylindrical core 130 is formed via rotocasting. In some embodiments, the mold used during rotocasting comprises a natural wood bark pattern resulting in a wood bark configuration on the external surface of the body 114.

[0046] In some embodiments, the two end caps 136 may be comprised of exterior grade plywood. Alternatively, the two end caps 136 may be comprised of a thermoplastic such as ABS or polyurethane. In some embodiments, the hollow semi-cylindrical core 130 and the two end caps 136 are rotocasted from the same mold. Alternatively, the hollow semi-cylindrical core 130 is rotocasted in a separate mold from the two end caps 136, and assembled after removal from the mold. In some embodiments, the two end caps 136, may be bolted or riveted to the hollow semi-cylindrical core 130. The two end caps 136 are configured to mount the raised central ridge 148 of the base 112.

[0047] In some embodiments, the body 114 may further include a body cover. The body cover may be natural wood bark. Preferably, the bark is subjected to a kilning process that stabilizes the bark and sets the bark in the correct curvature to match the curvature of the hollow semi-cylindrical core 130. The body cover may also be a polymeric material configured to resemble wood bark. Suitable polymeric materials include: ABS, polyurethane, as well as other thermoplastics. In some embodiments, where the animal feed trough 100 comprises a body cover, the body cover may be attached by a weak adhesive, or mechanically attached by clips, latches, pins or other similar attachment devices. The body cover may be non-permanently mounted to the body, this would allow for removal if desired and replacement with different bark or with some other surface treatment. Alternatively, the body may be absent a body cover and the hollow semi-cylindrical core 130 may have a surface treatment configured to resemble natural wood bark.

[0048] The base 112 is substantially the same as the base 12 described in the previous embodiments. The base 112 has a generally triangular shape to facilitate the flow of grain through the feed slots 152. The body 114 is mounted above a raised central ridge 148 that extends along the length of the base 112 and form feed slots 150 through which gravity-fed grain flows from the interior of the body 114. The base 112 has a series of downstream feed dishes 152, separated by raised ribs 156, which capture and accumulate the grain that falls by gravity through the feed slots 150. Molded in feed stops 154 will retard most of the grain from continuing down the feed dishes 152 onto the surrounding ground. The feed dishes 152 are wide and flat and therefore minimize choking or jamming of the grain as it feeds out of the animal feed trough 100, as is the case with many other gravity feeders that attempt to transport grain from a large bin through narrow tubes. The feed dishes 152 extend laterally along the length of the trough 100, promoting even flow of grain along the length of the animal feed trough 100 and permitting several animals to feed at the same time. Placement of the feed dishes 152 on both sides of the trough 100 further promotes even flow of grain along the length of the animal feed trough 100 and permits several animals to feed at the same time on opposite sides of the animal feed trough 100. The feed dishes 152 are defined by raised ribs 156 which extend downwardly from the central ridge 148. As described with the previous embodiments, the ribs 156 include notches into which the hollow semi-cylindrical core 130 is positioned. While the angle of declination of the feed dishes 152 may vary, in one preferred embodiment the angle of declination of the feed dishes 152 is 25 degrees, but may optionally be between 15 and 35 degrees. In some embodiments the base 112 further includes a flow adjuster to modulate the flow of grain into the feed dishes 152. In some embodiments, the flow adjuster is a mesh lining covering the opening. Additionally, or alternatively, the flow adjuster is a lip affixed to the inside edge of the body 130 configured to slow the flow of grain into the feed dishes 52. The base 112 may be comprised of a thermoplastic such as ABS or polyurethane. In some embodiments, the base 112 is formed via rotocasting.
