DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] While the presently disclosed inventive concept(s) is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the inventive concept(s) to the specific form disclosed, but, on the contrary, the presently disclosed and claimed inventive concept(s) is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the inventive concept(s) as defined in the claims.

[0020] In the following description and in the figures, like elements are identified with like reference numerals. The use of e.g., etc, and or indicates non-exclusive alternatives without limitation unless otherwise noted. The use of including means including, but not limited to, unless otherwise noted.

[0021] FIG. 1 is a perspective view of an embodiment of the wheel 10 for supporting an irrigation frame and line (not shown). In the depicted embodiment embodiment, the wheel 10 includes a body 12 defined as a generally planar disc having a second side 14 (not shown) and an opposing first side 16. Though the body may be made of a variety of materials and be of various thicknesses, in a preferred embodiment the body is made of steel, though and 3/16 may also be employed, among other thicknesses. The wheel 10 includes a hub 18 and defines a circumference 30. In the preferred embodiment, the feet overlap the body and ring 26 2.5. Tis construction is thought to provide maximum compatibility with a variety of common frame gear box and axle shaft configurations, though hub 18 variations may be employed to accommodate different gearbox and axle arrangements without deviating from the scope of invention disclosed herein.

[0022] FIG. 1 illustrates a plurality of channel shaped feet attached to the disc body 12. Each foot 20 has a first longitudinal end 22 and a second longitudinal end 24. When viewed from the first longitudinal end 22 to the second longitudinal end 24, each foot has a U-shaped profile, with a base 26 and flanges 28. In the preferred embodiment, the base of each foot 20 is 5 wide, though other widths and flange heights may be employed. While each foot may be independent fabricated, the feet may alternatively be cut from a source channel, such as channel steel, for efficiency and to provide uniformity. Each foot 20 is attached to the body 12 at an attachment point located between the first longitudinal end 22 and the second longitudinal end 24 of the foot 20 such that the flanges 28 of the U-shaped profile extend radially away from the hub 18. The flanges 28 of each foot 20 extend beyond the circumference 30 to enable the flanges 28 to engage with the ground during operation. FIG. 1 also depicts the gaps 38 between otherwise adjacent feet 20. These gaps 38 allow snow, mud, or other debris to pass through the wheel 10 and minimize loss of traction.

[0023] FIG. 1 also depicts the anchors 40, shown as eight bolts, inserted at the hub 18 of the wheel 10 and used to attach the wheel 10 to the frame (not shown) while allowing the wheel 10 to rotate. Also shown are five braces 52 radiating from the hub 18 of the first side 16 of the body 12 and each attached to a foot 20 for additional support.

[0024] FIG. 2 is a perspective view of the irrigation wheel 10 attached as seen from the second side 14 of the wheel 10. FIG. 2 also demonstrates that the first longitudinal end 22 of each foot 26 extends beyond the second side 14 of the body. FIG. 2 illustrates an embodiment in which the second longitudinal end 24 of each foot 26 extends beyond the ring support 36 connecting each foot. Flanges 36 are wider at the base than at the distal end from the base of the flange.

[0025] FIG. 3 illustrates the extension of the second longitudinal end of the foot beyond the ring support. In a preferred embodiment, the first longitudinal end 22 of a foot 20 extends beyond the second side 14 by 2.5, though other extension lengths may be used or alternatively the ring may be attached to the second longitudinal end. Also shown is the radial extension of the flanges 28 to enable the wheel 10 to engage with the ground.

[0026] FIG. 4 is a closer perspective view of some of the first longitudinal end 22 of a foot 20 from the first side 14 of the irrigation wheel 10. This view more closely depicts the recess 32 in the circumference 30 into which each foot is inserted and attached.

[0027] FIG. 4 is an alternative perspective view from the first side 16 of the irrigation wheel 10. In the embodiment shown, the circumference 30 contains a plurality of recesses 32 and each foot 20 is attached to the body at the circumference 30 via the recesses 32. This view more closely shows the attachment of the second longitudinal end 24 of each foot 20 to the circular support loop 36. Also depicted are the anchors 40 at the hub 18 of the wheel 10, and the braces 52 attached to the first side 16 of the body 12, with each brace 52 spanning from the hub 18 of the body 12 to a foot 20.

[0028] FIG. 5 is an perspective vie of an embodiment illustrating the ring support 36 aligned with the second longitudinal end of the foot. The ring can be constructed of a single component or of multiple components.

[0029] FIG. 6 is a cutaway view of the disc body 12 having foot 20 shown detached and alongside the body. The foot 20 is positioned and connected within the groove 33 to construct the operational wheel. In a preferred embodiment the shape of indentation 33 matches the shape of the channel 20, whether that be in a U shape as shown or in an alternative shape such as a V.

[0030] While certain preferred embodiments are shown in the figures and described in this disclosure, it is to be distinctly understood that the presently disclosed inventive concept(s) is not limited thereto but may be variously embodied to practice within the scope of the following claims. From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the disclosure as defined by the following claims.
