DETAILED DESCRIPTION OF THE INVENTION
[0034] While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.
[0035] To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as “a”, “an” and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims.
[0036] The present invention improves on known steer roping practice devices by providing the trainee with indicia of the best time to rope the hind legs of an animal. The hind legs of the mechanical roping practice apparatus are generally roped or lassoed when the hind leg or legs are moving along a forward portion of the arc of movement, during a hop, until the rear legs are perpendicular to the ground as the legs move forward. Even when it is possible to rope the hind legs at a position forward from the position at which the rear legs are perpendicular to the ground, it is not considered to be good roping technique. The present invention can be used for a wide variety of roping applications. While the examples herein are shown with a steer as an exemplary animal, many other animals for which roping practice may be sought are also encompassed by the present invention, such as but not limited to, bovine, ovine, equine, swine, which animals can be young or full grown. The present invention is shown using a steer as an example, and the present invention includes mechanical training devices for any animal for which roping practice is sought.
[0037] Unlike other known steer roping practice devices, in one embodiment the present invention provides a combination of movement of the legs along the ground and in the air, while at the same time mimicking the jumping motion of the steer. The present invention provides the indicia of when the proper roping technique is used by indicating the correct time to rope the hind leg or legs, and then turns off when the incorrect time for roping is indicated. Therefore, the user and observers of the roping practice can track if proper technique is applied, but also when the hind leg or legs are roped, reflecting incorrect roping technique.
[0038]
[0039] The indicium shown in the figures is light, however, the skilled artisan will recognize that sound or vibration may also be used as one of the indicia, which indicia are not mutually exclusive, that is, more than one indicium may be used at the same and/or different times. Any variation of the same is encompassed by the present invention, as are various positions (for visual cues) for the indicium. If using sound, for example, the sound can be varied to indicate the proper time to rope the hind leg member or leg members 28, such as using a tone that changes pitch, intermittent sound that indicates with an increase in pitch or volume, or the presence or absence of sound, or any combination thereof, to indicate to the user when is the best time in the cycle to rope the hind leg member or leg members 28. The volume of the sound and/or intensity or rate of intermittent sound may be used to indicate to the user when the proper time is approaching, during the duration of the proper roping time, when the time is ending, and when it is not proper technique to rope. Likewise, the light or visual cue can be varied in similar manner, e.g., with the lights on or off, with a change in the rate of blinking of the light(s), by having a red (no-go) versus green (go), or even a spectrum of color and/or intensity to indicate to the user when the proper time is approaching, during the duration of the proper roping time, when the time is ending, and when it is not proper technique to rope. An example of a visual cue includes an indicator that has up or down arrows, a flag, a wheel with one color for go and another for stop, stop and go signaling, or other indicator whether mechanical or in the form of a light (or both light and mechanical) that can be seen by the user during roping practice. Another indicium is vibration, which could be a device carried or worn by the user (non-limiting examples including a smartphone, a smartwatch, and/or other dedicated device) that provide the user with vibration that indicates to the user when the proper time is approaching, during the duration of the proper roping time, when the time is ending, and when it is not proper technique to rope.
