## Background
CROSS-REFERENCE TO RELATED APPLICATION
The present application is a continuation-in-part of related prior provisional applications: Ser. No. 60/498,844 filed Aug. 29, 2003, entitled “HEELING/HEADING ROPING PRACTICING SYSTEM”; and Ser. No. 60/463,551 filed Apr. 17, 2003, entitled “HEELING/HEADING ROPE PRACTICING SYSTEM”; the contents of which are incorporated herein by this reference and are not admitted to be prior art with respect to the present invention by their mention in this cross-reference section.


BACKGROUND
This invention relates to providing a system for assisting a user in practicing roping skills, particularly heeling and heading roping skills. For example, team roping is a timed contest in a rodeo that features two cowboys competing together: a “header” and a “heeler”. The header ropes the steer's head (ideally the horns), dallies (wraps the end of the rope around his saddle horn) and pulls the steer with the rope. The heeler then ropes the back legs of the steer, dallies, and stops his horse. When the heeler catches and dallies, and both ropes are tight, the header stops and turns his horse to face the heeler, and the clock is stopped. The team with the fastest time wins the competition.
To be competitive, those participating in such competitions must practice to develop a high degree of skill in throwing the rope. For many reasons, it is often inconvenient or impractical to practice with a live steer. In the past, different kinds of mechanical roping steers have been developed to assist in roping training. However, the devices of the past which provide automated movement simulating a steer (to provide a more valuable training experience) have been complicated, bulky, and cumbersome to assemble and disassemble. In the past, mechanically-powered roping practice systems have required nearby sources of electric power.
Further, in the past, providers of roping practice systems have not provided much incentive to purchase their systems. Attempts to advertise and sell roping practice systems by traditional means have been relatively ineffectual.
OBJECTS AND FEATURES OF THE INVENTION
A primary object and feature of the present invention is to provide a heeling/heading rope practicing system which assists a user in practicing heeling/heading roping skills.
It is a further object and feature of the present invention to provide such a system that provides automated movement simulating a steer. It is a further object and feature of the present invention to provide such a system that does not require an external source of electricity for mechanized movement. It is a further object and feature of the present invention to provide such a system that is lightweight, compact, and easy to assemble and disassemble.
A further primary object and feature of the present invention is to provide such a system that is efficient, inexpensive, and handy.
It is a further object and feature of the present invention to provide a method of promoting the sale of such rope practicing systems. It is a further object and feature of the present invention to provide such a method in conjunction with events in which potential purchasers already participate. It is a further object and feature of the present invention to provide such a method that provides multiple incentives for team roping participants to purchase such rope practicing systems. It is a further object and feature of the present invention to provide such a method that requires purchase of such rope practicing systems in order to be eligible for contest prizes.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
FIG. 1 is a side view of roping practice system 200, according to a preferred embodiment of the present invention, showing user 100 practicing roping. Preferably, user 100 practices throwing rope 102 around legs 202 of roping practice system 200. Preferably, legs 202 are attached to a driving mechanism 208 (See FIG. 4) which provides motion to legs 202, which simulates the motion of a bovine's legs, so that user 100 is provided with a more realistic and more useful practicing experience. Preferably, driving mechanism 208 is protected by housing 204. Upon reading this specification, those skilled in the art will now understand that, under appropriate circumstances, considering issues such as user preference, production cost, ease of accessing and repairing the driving mechanism, etc., other housing arrangements may suffice, such as, for example, other shapes, other materials, omitting the housing, etc. Preferably, driving mechanism 208 is supported by support 206 (embodying herein support means for supporting such pendulum means), as shown. Preferably, support 206 and driving mechanism 208 are arranged to support legs 202 in a position hanging in the air above the ground, as shown. Preferably, support 206 is inserted and into receiver 306 of stand 300, as shown.
Preferably, receiver 306 is supported about 18′′ above the ground (a height similar to a standard receiver hitch of a vehicle) by receiver support 304, as shown. Preferably, receiver 306 is structured and arranged with dimensions similar to a receiver of a standard 2′′ towing hitch. Preferably, receiver support 304 is connected to base 302, as shown. Preferably, Base 302 provides stable support for receiver support 304. Preferably, stand 300 is made of metal, most preferably steel, for strength and durability. Upon reading this specification, those skilled in the art will now understand that, under appropriate circumstances, considering issues such as production cost, market demand, weight, durability, etc., other types of support arrangements may suffice, such as for example, making portions of stand 300 out of aluminum to reduce weight, or wood or plastic, etc., to reduce cost, or different stand geometries, etc.
FIG. 2 is a front view of roping practice system 200. Preferably, legs 202 are connected by crossbar 212, which reinforces the rigidity of legs 202. When user 100 successfully ropes legs 202, crossbar 212 helps legs 202 resist bending together from the force exerted by the rope 102.
Preferably, driving mechanism 208 is a spring motor mechanism similar to the mechanism found in U.S. Pat. No. 6,283,870. Preferably, driving mechanism 208 comprises crank 214 for winding spring 207 of driving mechanism 208. Preferably, spring 207 is a torsional spring, which mechanically stores potential energy by increasing (or decreasing) the number of coils in spring 207. Preferably, user 100 turns crank 214 (embodying herein at least one winding mechanism to wind such at least one spring), thereby winding spring 207 within driving mechanism 208, thereby mechanically storing potential energy in driving mechanism 208. Upon reading this specification, those skilled in the art will now understand that, under appropriate circumstances, considering issues such as production cost, market demand, intended use, proximity to electricity, etc., other driving mechanisms, such as for example, electric motors (which may for example, adversely affect portability, but favorably affect the amount of power supplied by the driving mechanism), etc., may suffice.
FIG. 3 is a sectional view through the section 3—3 of roping practice system 200. FIG. 4 is a section view through 4—4 of roping practice system 200. Preferably, legs 202 (embodying herein leg means for acting as a ropable leg system of a bovine animal; and embodying herein at least one leg system to act as a ropable leg system of a bovine animal) are weighted sufficiently in coordination with driving mechanism 208, so that legs 202 swing back and forth with pendular motion 210 (such arrangement embodying herein wherein such at least one leg system is structured and arranged to function as a pendulum). Preferably, driving mechanism 208 drives the pendular motion 210 of legs 202 by converting mechanical potential energy stored in spring 207 into driving force. Preferably, driving mechanism 208 (embodying herein driving means for driving such pendulum means; and embodying herein at least one driver coupled to such at least on leg system to drive pendular motion of such at least one leg system) drives in sympathy with the natural frequency of pendular motion 210 of legs 202 to most efficiently maintain amplitude of pendular motion 210 by overcoming energy losses from friction, etc.
FIG. 5 is a simplified symbolic representation of legs 202 as a pendulum 500. The center of mass 504 of pendulum 500 is determined by the distribution of mass throughout the pendulum 500. The range of motion of legs 202 (pendulum 500) is partially determined by the location of the center of mass 504 in relation to the geometry of pendulum 500. For example, the range of motion of the legs 202 can be shifted by changing the location of a concentrated mass 502 from hoof 510 (as shown) to knee 508. Periodicity of pendulum 500 depends on how far the center of mass 504 is from pivot point 506. The farther the center of mass 504 from pivot point 506, the longer the period will be. By having a concentrated mass 502 far from pivot point 506, the period of motion can be lengthened, while minimizing overall mass of pendulum 500 (thereby allowing roping practice system 200 to be less cumbersome and more portable). Preferably, legs 202 have a concentrated mass 502 near the hoof 510, as shown. Preferably, at least 50% of the mass of legs 202 is concentrated in the hoof 510 (defined herein as the lower 20% of legs 202) furthest from pivot point 506. Upon reading this specification, those skilled in the art will now understand that, under appropriate circumstances, considering issues such as desired periodicity for legs, user preference, etc., other distributions of mass, such as for example, having a concentrated mass near knee 508 to produce a quicker period of motion, etc., may suffice.
By suspending legs 202 in the air above the ground and weighting legs 202 properly to achieve pendular motion 210, motion of the legs 202 is assisted by gravity, and therefore, the amount of energy required to maintain motion of legs 202 is significantly less than prior art systems. The energy required to maintain motion of the legs 202 is low enough that a hand cranked driving mechanism 208 is sufficient to drive pendular motion 210 of the legs 202 for a significant amount of time. Such a hand-cranked driving mechanism is compact, lightweight, and less cumbersome than prior art roping practice systems with drive mechanisms.
Preferably, receiver support 304 is connected to base 302 with a quick-release fastening mechanism, preferably, a clevis pin 310 and retainer clip 312, as shown. Upon reading this specification, those skilled in the art will now understand that, under appropriate circumstances, considering issues such as production cost, market demand, user preference, etc., other types of fastening mechanisms, such as for example, nuts and bolts, etc., may suffice. Preferably base 302 comprises a sheet of metal. Preferably, receiver 306 is welded to receiver support 304. Preferably, support 206 slides into receiver 306 and is held in place by clevis pin 310 and retainer clip 312, as shown.
