Downward force on the foot pedal is translated to the leg causing the leg to whip upward and launching the ball with proportional force and speed. In one embodiment, the frame is collapsible/expandable and includes a roller to facilitate transportation. In another embodiment, the leg is formed of pliable material to eliminate the risk of injury in the event of collision therewith.
Description




FIELD OF THE INVENTION




The present invention relates in general to athletic training equipment, and, more particularly, to an apparatus that imitates the kicking of a ball by a player.




BACKGROUND OF THE INVENTION




In football, rugby and soccer, as well as other sporting or athletic contests which utilize a ball, kicking or punting the ball is often part of the game. In football, the player punting the ball is often rushed by the opposing team in an attempt to block the punt and, therefore, prevent the ball from moving down field. There has not been a practical manner in which to practice blocking of a punt without running at full speed towards an actual kicker. Unfortunately, this can lead to injury of both the blocking and the punting player.




Apparatus exists for pitching or throwing footballs and baseballs such as the Football Passing Machine commercially-available from the Jugs Company, Tualatin, Oreg. 97062. Such apparatus consists of one or more motor-driven wheels. The ball is dropped into contact with the rotating wheels and is accelerated into a trajectory depending on the angular orientation of the rotating wheels and the speed thereof. Although such devices can simulate the trajectory of a punt, it is not advisable to run full speed towards such a device without the risk of injury.




According, a need exists for an apparatus which enables players to practice punt blocking and which reduces the likelihood of injury to one or more players.




A further need exists for an apparatus in which the kicking or whipping motion of a leg during a punt exercise is mimicked and which can create a realistic trajectory for the ball.




A further need exists for an apparatus in which the element and launching the ball has the same shape and rigidity of a human appendage.




A further need exists for an apparatus which is capable of imitating the motion of a leg in the process of kicking a ball and which can be controlled so as to simulate different kicking techniques.




SUMMARY OF THE INVENTION




The present invention provides an apparatus that simulates punting and place kicking. The apparatus comprises a pair of upright posts secured to an expandable frame. An elongate member, such as a prosthetic leg having a cradle at the foot region thereof, is pivotally mounted intermediate the set of posts. The leg is mechanically coupled via a cable or other mechanism to a foot pedal that is mounted to another of these posts. When force is delivered to the foot petal, the leg whips up with the same velocity of a kicker swinging through a kicking motion. When the leg is whipped, the ball flies off the foot cradle and into the air imitating the trajectory of a kick. A blocker can get a full extension during approach and dive at the block point in an effort to take the ball off the leg. The leg is preferably made from a pliable material such as molded rubber to eliminate the risk of injury, should a collision occur between the blocker and the leg. In one embodiment, the frame is padded and may be extended and collapsed for ease of transportation.




According to a first aspect of the invention, an apparatus for launching a ball comprises: (a) a rigid frame; (b) an elongate first member movably mounted to the frame; (c) the first member having a first end thereof shaped to receive an object; (d) a second member mounted to the frame; (e) means for mechanically coupling the first member to the second member so that force is transferable from the second member to the first member; and (f) the first member pivotal relative to the frame upon receipt of force transferred to the first member from the second member so that an object received at the first end of the first member is launched. In one embodiment, the second member is pivotally mounted to the frame and further comprises a first end shaped to receive force applied to the second member. In another embodiment, the first member and second members each have a second end coupled to the means for mechanically coupling and wherein the means for mechanically coupling the first member to the second member comprises a cable.




According to a first aspect of the invention, an apparatus for imitating kicking of an object comprises: (a) a rigid frame; (b) a first projection extending outward from the frame; (c) a first member movably mounted to the first projection; (d) a mechanism at a first end of the first member shaped to receive and retain an object therein; (e) a second member mounted to the frame; (f) means for mechanically coupling the first member and the second member; and (g) the first member pivotal relative to the first projection so that an object retained in the indentation at the first end of the first member is launched upon receipt of force transferred to the first member from the second member.




According to a third aspect of the invention, an apparatus for launching a ball comprises (a) a rigid frame (b) a prosthetic leg movably mounted to the frame; (c) the prosthetic leg shaped to seat a ball therein; (c) a pedal pivotally mounted to the frame; (d) a cable coupling the prosthetic leg to the pedal so that force applied to the pedal is transferable to the prosthetic leg; and (e) the prosthetic leg pivotal relative to the frame so that a ball seated in the indentation of the prosthetic leg is launched upon receipt of force by the pedal. According to a sixth aspect of the invention, the rigid frame comprises a pair of telescoping members that are collapsible to facilitate the movement of the unit. In one embodiment, the rigid frame comprises members that are collapsible to facilitate the movement of the apparatus.




According to a fourth aspect of the invention, a method for imitating the launching of an object comprises: (a) providing an apparatus having a frame with first and second members movably mounted to the frame, the first and second members mechanically coupled, the first member having a first end and shaped to receive an object; (b) placing an object into the first end of the first member; and (c) applying force to the second member so that the force is transferred to the first member causing the first member to pivot relative to the frame and further causing the object to disengage the first member.




According to a fifth aspect of the invention, a method for facilitating controlled launching of an object comprises: (a) providing a rigid frame; (b) movably mounting a first member to the frame, the first member having a first end shaped to receive an object; (c) movably mounting a second member to the frame; (d) mechanically coupling the first member to the second member so that force can be transmitted from the second member to the first member causing the first member to pivot relative to the frame so that an object received at the first end of the first member will be launched from the first member.

16


is fully extended, as illustrated in

FIG. 1

, the holes in section


16


A align with the hinge lock plates


114


projecting from section


16


B so that locking pin


26


B may be inserted therethrough fixing the bridge


16


into an extended position. As illustrated in

FIG. 1

, a set of three locking pin


26


A-C are attached to bridge


16


via chains


17


which may be secured to the respective sections of bridge


16


. Locking pin


26


A is aligned with and insertable into the positioning holes contained within hinge brackets


80


while locking pin


26


C may be aligned with and insertable into the positioning holes contained within hinge brackets


90


. When bridge


16

16


is in a fully collapsed position, locking pin


26


B may double as a transport locking pin and be inserted into the positioning hole extending through position rods


84


and positioning pipes


94


, when properly aligned.




In an alternative embodiment, bridge sections


16


A-B may be either rectangular or tubular in shape and of complimentary dimensions to allow for intercoupling in a telescoping manner. With such embodiment, rather that pivoting relative to assemblies


12


and


14


, bridge sections


16


A-B would slide relative to each other to so that their collective length increases or decreases the distance between assemblies


12


and


14


. A locking pin may also be used to secure bridge sections


16


A-B at one or more different length positions.




In still other alternative embodiments, bridge sections


16


A-B may be replaced with a single section


16


that is either fixed to assemblies


12


and


14


or removably fixed thereto to allow for moving of the apparatus as separate assemblies.




A cable mount


116


secured, typically by welding, to the end cap of leg mount cylinder


68


is used to mechanically couple the leg mount assembly


54


to the cable


22


. In the illustrative embodiment, cable


22


may be implemented with vinyl coated wire rope. Each end of cable


22


is secured to a cable and lock


118


. In addition, a cable clip


120


couples the cable end lock


118


of cable


22


to the extension of pedal arm


30


, as illustrated.




In the illustrative embodiment, leg


18


may be made of a semi-flexible material, such as molded rubber, which mimics the softness of a human leg and is able to transfer energy to the ball in a manner which mimics a human leg kicking the ball. The shape of leg


18


, in an illustrative embodiment, mimics that of a human leg to add realism to the blocking exercise. It will be obvious to those reasonably skilled in the arts that other materials may be utilized for leg


18


. The mechanism used to hold the ball in place may be implemented in a number of different ways including a substantially arcuate indentation in the surface of the leg


18


or a raised, cup-like projection


19


shaped to seat the ball at the end of leg


18


. Alternatively, in place of, or in addition the above described configurations, mechanisms may be used to frictionally attach the ball to leg


18


. Such devices may comprise a dense array of tiny hooks on leg


18


and a complimentary mating dense fabric pile on the ball, e.g. VELCRO™, that when pressed together frictionally retain the ball on leg


18


. Alternatively, complimentary magnetic material on the ball and leg


18


may be utilized to temporarily retain the ball on leg


18


.




To utilize the apparatus


10


, the operator utilizes roller


46


to position the apparatus where desired, preferably on a level surface. The locking pin


26


B is then removed from the bridge section


16


A-B while the apparatus is in the collapsed position, as illustrated in FIG.


2


A. Next, outward force on the opening handle


48


in the direction of the arrows shown in

FIG. 2B

will cause the apparatus to expand into a fully-extended configuration, as illustrated in FIG.


2


B. Pins


26


A-C may then be inserted into their respective positioning holes along bridge


16


. If not already connected, the cable


22


may be connected to pedal arm


30


using the cable clip


120


. Leg


18


, if not already coupled to leg mount assembly


54


may be secured to leg mount cylinder


68


. Note that the actual extent to which the leg bolt


38


extends into leg


18


may be set with the position of a nut carried by bolt


38


. Finally, protective pad


20


may be secured to the leg swing posts


58


.




The apparatus


10


is then ready for use. The operator places a ball onto the free end of leg


18


so that the ball rests within the indentation at the free end. Downward force on foot pedal


28


causes the pedal arm


30


to pivot relative to post


88


causing the cable


22


to be retracted toward the operator. This force is translated via cable


22


and pulley


52


to the leg mount assembly


54


causing leg


18


to pivot upward from its resting position and causing the ball to be launched from the indented end of leg


18


.




Utilizing the apparatus


10


as described herein, an operator may use varying amount of force on the pedal


28


causing the ball to be kicked or punted with an amount of force and speed related to that delivered to the foot pedal. The apparatus of the present invention facilitates blocking practice of punts and kicks without substantial risk of injury to either the operator or the blocking players.
