Description




FIELD OF THE INVENTION




The present invention pertains generally to equipment for training football players, and more particularly to equipment for increasing a football player's strength while also improving the player's functional technique, e.g., in blocking.




BACKGROUND OF THE INVENTION




Successful players of American style football possess at least two important characteristics, physical strength and endurance, and highly developed functional skills and techniques for applying such strength and endurance to particular game situations and positions. For example, for a lineman, such as an offensive lineman, strength and endurance is required to block opposing players of similar size and strength repeatedly play after play. A finely honed functional technique is required to ensure that the lineman's strength is applied properly so that the opposing player does not slip or evade the block or such that the block does not result in a penalty such as for holding. Thus, in training football players, such as lineman, it is important to develop both strength and endurance as well as functional playing technique.




For the most part, a football player's strength and endurance and playing technique have been developed and trained separately. For example, strength and endurance can be gained in the weight room, by weight training using, e.g., free weights or other strength building equipment. Weight training can be very effective for the player in gaining raw strength and endurance. Furthermore, such weight training is measurable. A coach or trainer can easily see that a player is gaining strength and endurance as the player is able, for example, to press more weight for more repetitions.




The functional aspects of play, i.e., the application of raw strength and endurance to particular skills and techniques, may be learned in practice through game play and practice scrimmages, that is, through live practice. However, such live practice is naturally limited to specific practice times when skilled coaches and other players are available. Furthermore, rules in some leagues limit the numbers of such practices. Moreover, there is a significant risk of injury in any live practice situation. For these reasons, the use of live practice to enhance a football player's functional technique is often very limited.




As a supplement to live practice situations, various types of football training equipment have been developed and used to allow players to practice their techniques without facing off against another live player and, in some cases, even without the need for the presence of a coach or trainer. A common example of such training equipment is the conventional football training sled for teaching functional techniques such as tackling and blocking. A typical football training sled includes a horizontal base including one or more sled like runners, and a padded vertical extension mounted at one end of the sled base. The padded portion of the sled may be sized and shaped to represent an opposing player. A lineman may practice blocking techniques, for example, by blocking against the padded portion of the sled, driving the sled straight backward as he would an opposing player. Weight may be added to the sled to increase the effort required to drive the imitated opposing player back off the line. Some more advanced training sleds include a mechanism which allows a player both to drive the sled backward and to lift the padded portion of the sled without lifting the entire sled. This simulates player hip rotation which converts the horizontal movement generated forwardly by the player into a force with a vertical component which tends to lift the opposing player so as to render him momentarily helpless. In at least one such training sled the padded portion of the sled is mounted on a telescoping arm. A mechanism is provided which prevents rotation of the blocking pad upward unless the pad mounted on the telescoping arm has been driven rearward by a sufficient amount. Spring resistance provides resistance to rearward movement of the arm. See U.S. Pat. No. 5,462,272.




Typical football training equipment, such as training sleds, are used as tools for training and practicing functional technique, such as blocking, but do relatively little to increase strength and endurance in the particular functional application being taught or practiced. Furthermore, such training equipment is a tool for qualitative training only. With the use of such equipment, a coach or trainer can observe a player's technique and instruct him in required corrections and adjustments thereto. Such equipment does not provide for a quantitative measure of the effective application of the player's strength and endurance to the particular functional technique being taught in practice.




What is desired, therefore, is a football training apparatus that provides simultaneously for developing both a player's strength and functional technique in a manner such that the strength gain is both general in nature and concentrated as applied to the particular functional skills required of the player. Such a functional strength machine for football player training should provide for the quantitative enhancement of both the football player's strength and technique, e.g., in blocking, with or without the need for a coach. Such a football training apparatus should be usable both indoors and outdoors, and should be adjustable to accommodate players of various sizes, strengths, and skill levels.




SUMMARY OF THE INVENTION




The present invention provides a football training apparatus which may be used as a functional strength machine. A football training apparatus in accordance with the present invention allows a football player to develop his strength in a functional manner, such that physical strength is increased both generally and in a focused manner with regard to the particular functional technique to which the player's strength must be applied in a game situation. In particular, the present invention provides a football training apparatus which allows a lineman to develop and enhance his strength as applied functionally to blocking technique. A football training apparatus in accordance with the present invention may be used indoors and outdoors on all types of surfaces, with or without a coach or trainer. More than one player may use the apparatus simultaneously to practice combo or deuce blocking techniques. A football training apparatus in accordance with the present invention is adjustable for variously sized players, for players of different skill and ability levels, and to increase the strength required to be exerted by a player during the performance of a particular blocking technique using the apparatus as the player's strength increases. A football training apparatus in accordance with the present invention thus provides for a quantitative measure of the increase in a player's strength and ability, not just generally, but as applied functionally to a particular skill, e.g., blocking.




A football training apparatus in accordance with the present invention includes a frame structure including a horizontally oriented base and a vertically extending portion formed at a front end of the frame base and extending generally vertically therefrom. The entire frame structure is preferably made of a structurally strong and durable material, such as steel, which is preferably welded and/or bolted together with sufficient cross pieces to form a sturdy frame structure. The vertically extending portion of the frame structure preferably extends from the front end of the horizontal base at a slight angle thereto, such that the vertically extending portion of the frame also extends slightly forward from the front end of the horizontal base.




The frame is preferably supported on wheels, e.g., wheels are preferably provided at each of the four corners of the horizontal base. For example, caster wheels maybe provided at the front ends of the horizontal base, below the vertically extending portion of the frame structure, with larger treaded wheels provided at the rear of the base of the frame structure. The rear wheels of the apparatus are provided with independently operable braking mechanisms, such that the rear wheels are normally locked into position when the brake mechanisms are engaged, and the rear wheels are allowed to rotate freely when the brake mechanisms are released. For example, each of the rear wheels may be mounted on a drum, with movable brake pads mounted within the drum to engage the inner surface of the drum to prevent movement of the wheels when the brake mechanism is engaged. Other braking mechanisms, such as a disc brake system, may also be employed.




An actuator system assembly is mounted on the vertically extending portion of the football training apparatus frame structure. The actuator system assembly includes a support structure by which the actuator system assembly is mounted to the vertically extending portion of the frame structure. The actuator system support structure is preferably adapted to be secured to the vertically extending portion of the frame structure in various user adjustable positions, thereby to allow the height of the actuator system with respect to the frame to be adjusted for players of various sizes. Two parallel extending arms are mounted onto the support structure such that the arms extend forward from the apparatus in an extended direction and may be pushed backward in the direction of the apparatus in a retracted direction.




Padded strike pads are mounted at the forward distal ends of the extending arms. The strike pads are preferably sized and shaped to represent an opposing football player. For example, a strike pad mounted on the left extending arm maybe sized and shaped to mimic one half of the torso of an opposing lineman, with the strike pad mounted on the right extending arm sized and shaped to mimic the other half torso of an opposing lineman. The extending arms are positioned closely adjacent and parallel to each other such that the strike pads together mimic the torso and shoulders of an opposing football player. The strike pads may preferably be mounted to the forward distal ends of the extending arms so as to be rotatable within a limited range about a horizontal axis. The strike pads are thus able to tilt when struck to drive the extending arms rearward, thereby simulating a player gaining leverage over an opponent.




The extending arms are mounted within the actuator system assembly so as to be movable backward and forward, i.e., retracted and extended therein. This may be achieved by supporting the extending arms on rollers which, in turn, are mounted on the actuator system support structure. The rollers support the extending arms to provide smooth movement of the extending arms between the extended and retracted positions thereof.




A resistance mechanism is provided which biases the extending arms forward toward the extended position thereof and which resists movement of the extending arms in the rearward retracted direction. Preferably, the resistance mechanism is adjustable to allow for adjustment of the force required to drive the extending arms rearward. The resistance force required to drive the extending arms rearward is also preferably independently adjustable via the resistance mechanism for each of the right and left extending arms. The extending arm resistance mechanism may be implemented, for example, using elastic tension bands or cords extending between the rear ends of the extending arms, opposite the ends thereof to which the strike pads are attached, and the actuator system assembly support structure. By selecting the number (or resistance) of cords attached to the extending arms, the resistance force required to drive the extending arms rearward can be adjusted. Other extending arm resistance structures employing e.g., springs, pneumatics, etc. might also be employed.




The actuator system assembly also includes a brake actuation mechanism. The brake actuation mechanism is engaged when the extending arms are driven rearward by at least a selected amount. Independent right and left brake actuation mechanisms are preferably provided in association with the right and left extending arms, respectively, and are coupled to the corresponding brake mechanisms in the right and left rear wheels attached to the horizontal base frame structure of the apparatus. In accordance with the present invention, the brake mechanisms in the rear wheels are normally engaged, preventing movement of the football training apparatus, until the extending arms are driven rearward by a sufficient amount, by a football player pressing against the strike pads, to engage the brake actuation mechanisms provided in the actuator system assembly.




The brake actuation mechanism may, for example, be implemented using a brake actuation lever mounted to the actuator system support structure. The brake actuation lever is mounted to the support structure in a position thereon such that the lever is engaged by a back side of a strike pad when the extending arm on which the strike pad is mounted it is driven into the fully retracted position, against the resistance provided, e.g., by the elastic tension cords attached thereto. The brake actuation lever is movably, e.g., rotatably, mounted on the actuation system assembly support structure such that the lever is rotated about a pivot point when the back side of the strike pad contacts the brake actuation lever. The brake actuation lever is coupled to the brake mechanism formed in the rear wheel of the training apparatus by, e.g., a brake cable. When the brake actuation lever is engaged by the back side of the strike pad, the resulting rotational movement of the brake lever pulls on the brake cable, thereby disengaging the normally engaged brake mechanism, allowing movement of the corresponding rear wheel.




Preferably, separate brake levers are provided in association with each of the right and left strike pads and corresponding extending arms, with each such brake actuator lever coupled by a corresponding brake cable to the corresponding braking mechanism in the corresponding rear wheel of the football training apparatus. Thus, in order for both rear wheels to be released for movement, both strike pads must be driven rearward against the restraining force of the resistance mechanism to engage both of the brake actuator levers. If neither brake actuator lever is engaged, the training apparatus will not move. If only one of the brake actuator levers is engaged, only one of the rear wheels will be released, and the football training apparatus will rotate away from the player striking the strike pads. This simulates an opposing player evading a block which is not well centered or evenly applied. Thus, a football player using a football training apparatus in accordance with the present invention is able to improve blocking technique while increasing strength functionally, that is, as applied to blocking.




Combo or deuce blocking techniques, wherein two linemen combine efforts to block an opposing player, can be performed and practiced using a football training apparatus in accordance with the present invention. To practice such a maneuver, each practicing player engages one of the strike pads. The football training apparatus of the present invention teaches accurate synchronization of such a maneuver, in that the apparatus will move straight backward only if both rear brake mechanisms are released by the players driving both the right and left strike pads rearward with sufficient strength and proper coordination in time.




A football training apparatus in accordance with the present invention may further include a secondary brake release mechanism. The secondary brake release mechanism may be implemented as a hand brake release mounted, e.g., on a handle extending vertically upward from a rear of the base portion of the training apparatus frame structure, i.e., on the opposite side of the frame structure from the vertically extending portion thereof to which the actuator system assembly is mounted. Separate hand brake release mechanisms, mounted on separate rear handles, positioned side by side, may be provided for release of the brake mechanisms provided in each of the rear wheels of the football training apparatus. Each of the hand brake release mechanisms may be coupled by a brake cable to the corresponding brake mechanism. Thus, in accordance with the present invention, the brake mechanism in each rear wheel of the football training apparatus may be released alternatively by a player or players driving the strike pads positioned at the front of the training apparatus backward on the extending arms or by a coach or trainer positioned behind the football training apparatus and operating the hand brake release mechanisms. Thus, the coach or trainer may control release of the brake mechanisms to simulate various opposing player responses to a block. Alternatively, a player positioned behind the football training apparatus may disengage the rear wheel brakes using the hand brake release mechanisms in order to push the entire football training apparatus using the rear handles on which the hand brake release mechanisms are mounted. This allows the football training apparatus of the present invention to be used as a strength and speed developer without engaging the strike pads on the front of the machine.




Preferably, one or more vertical stanchions are provided on the horizontal base frame structure of the football training apparatus. The stanchions provide support for one or more conventional weight plates which may be loaded on the frame structure to increase the weight of the apparatus. Additional weight plates can be added to or removed from the frame to accommodate athletes of various strength levels for the pushing exercises, and to simulate opposing linemen of various sizes.




Further objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




An exemplary football training apparatus


20


in accordance with the present invention will first be described in overview with respect to the illustrations thereof in

FIGS. 1-3

. For clarity, some of the detail of the preferred components and mechanisms for implementing a football training apparatus in accordance with the present invention are not illustrated in

FIGS. 1-3

. However, further detail will be provided in subsequent drawings and corresponding written description.




A football training apparatus


20


in accordance with the present invention is formed on a frame structure


22


. The frame structure


22


has two basic components, a generally horizontally oriented base


24


, and a generally vertically oriented extending portion


26


, extending generally vertically from the base


24


at a front end thereof. As illustrated, the vertically extending portion


26


may extend both vertically and forward from the front end of the horizontal base


24


of the frame structure


22


at a slight angle, e.g., approximately 20°-30°, from vertical. Note that the frame structure


22


, including the horizontal base


24


and vertical extension


26


, may be formed of various cross pieces which form the horizontal base


24


and vertical extension


26


, which join the vertical extension


26


to the horizontal base


24


, and which, in general, ensure that the frame structure


22


is sufficiently strong and stable to support the other components of the football training apparatus


20


in a sturdy and rigid manner. The various components forming the frame structure


24


may, preferably, be formed of pieces made of a strong structural material such as, for example, steel, which may be welded and/or bolted together to form the frame structure


24


in a conventional manner. The various components forming the frame structure


22


and other components of the apparatus


20


are preferably painted, coated or otherwise treated to inhibit rust, corrosion, or other environmental damage to the apparatus


20


, as the entire football training apparatus


20


is preferably constructed to be used and stored both inside and outside, where the apparatus


20


may be exposed to various weather conditions.




The frame structure


22


is preferably supported by four wheels


28


-


31


, which, for future reference, will be referred to as the front left wheel


28


, the front right wheel


29


, the rear left wheel


30


, and the rear right wheel


31


. The front wheels


28


and


29


may preferably be implemented as caster wheels with solid rubber or plastic tires which are attached at or near the front left and right corners of the frame structure


22


in a conventional manner so as to pivot around a vertically oriented axis with respect thereto. Thus, the front caster wheels


28


and


29


preferably allow for easy turning of the football training apparatus


20


. The front wheels


28


and


29


of a football training apparatus


20


in accordance with the present invention are preferably freely rotatable at all times.




The rear wheels


30


and


31


of a football training apparatus


20


in accordance with the present invention are preferably larger than the front caster wheels


28


and


29


, and may include treaded tires. The rear wheels


30


and


31


are preferably mounted at or near the rear of the horizontal base


24


of the frame structure


22


, e.g., by a conventional axle structure


32


. The rear wheels


30


and


31


preferably also incorporate brake mechanisms therein which are normally engaged to prevent rotation of the rear wheels


30


and


31


until the brake mechanisms are released. An exemplary rear wheel assembly and brake mechanism therefore will be described in more detail below. It should be understood that various types, and sizes of front


28


,


29


and rear


30


,


31


wheels may be employed for a football training apparatus


20


in accordance with the present invention. In a preferred embodiment, the size and type of wheels


28


-


31


employed are selected to allow the football training apparatus to be used both inside and outside on a variety of surfaces including, e.g., grass.




Left


34


and right


35


rear handles are preferably provided extending rearward and upward from the horizontal base portion


24


of the frame structure


22


, on the opposite side thereof from the vertically extending portion


26


. The rear handles


34


and


35


may be mounted to the frame structure


22


in a conventional manner, e.g., by welding or by using conventional fasteners. The rear handles


34


and


35


are preferably shaped and positioned with respect to the frame structure


22


to allow an individual positioned at the rear side of the football training apparatus to grasp the handles


34


and


35


and push the entire football training apparatus


20


in a forward direction. As will be discussed in more detail below, the rear handles


34


and


35


preferably include hand brake release mechanisms mounted thereon to release the normally engaged braking mechanisms in the corresponding rear wheels


30


and


31


, respectively.




Stanchions


36


, or other, similar, support structures, are preferably provided on the horizontal base portion


24


of the frame structure


22


for supporting conventional weight plates


38


which may, thereby, be easily loaded onto and removed from the frame structure


22


. Weights


38


may be added to and removed from the stanchions


36


to alter the weight of the football training apparatus to accommodate athletes of various strength levels which may use the football training apparatus for pushing exercises, and to simulate opposing players of various sizes, as will be discussed in more detail below.




An actuator system assembly


40


is mounted to the vertically extending portion


26


of the frame structure


22


. The actuator system assembly


40


will now be described in more detail with reference to

FIGS. 4 and 5

. The actuator system assembly


40


includes an actuator system support structure


42


. The actuator system support structure


42


is the structure by which the actuator system assembly


40


is attached to the vertically extending portion


26


of the frame structure


22


. The actuator system support structure


42


also provides support for the other components of the actuator system assembly


40


, as will be discussed in more detail below.




As illustrated in

FIG. 4

, for example, the actuator system support structure


42


may include horizontally oriented cross pieces


44


. Attached to the ends of the cross pieces


44


are left and right vertically oriented sleeve structures


46


. The actuator system support structure


42


may be formed, e.g., of steel or another structural material, with, for example, the crosspieces


44


securely welded to the end sleeves


46


. The end sleeves


46


are sized and shaped to fit around corresponding left and right posts forming the sides of the vertically extending portion


26


of the frame structure


22


. A slight clearance is provided between the interior surfaces of the sleeves


46


and the outer surface of the side posts of the vertically extending portion


26


of the frame structure


22


, such that the actuator system support structure


42


and, therefore, the entire actuator system assembly


40


, may be slid up and down in position on the vertically extending portion


26


of the frame structure


22


, thereby to adjust the height of the actuator system


40


with respect to the frame structure


22


.




Apertures


48


are formed in the sleeve ends


46


of the actuator system support structure


42


. The apertures


48


formed in the sleeves


46


are positioned thereon to be aligned with corresponding apertures


50


formed in the vertically extending portion of


26


of the frame structure


22


to which the actuator system assembly


40


is mounted. A plurality of such apertures


50


are formed at intervals along the length of the vertically extending portion


26


of the frame structure


22


. The height of the actuator system assembly


40


with respect to the frame structure


22


is selected and established by aligning the apertures


48


in the sleeves


46


forming the ends of the actuator system assembly support structure


42


with corresponding apertures


50


formed in the vertically extending portion


26


of the frame structure


22


at the desired height for the actuator system assembly


40


. Locking pins


52


may then be extended through the apertures


48


and


50


formed in the support structure sleeves


46


and vertically extending portion


26


of the frame structure


20


, respectively, thereby to lock the actuator system assembly support structure


42


in position with respect to the vertically extending portion


26


of the frame structure


20


. Preferably, the apertures


48


and


50


in the support structure sleeves


46


and vertically extending portion


26


of the frame structure


22


are formed, and the locking pins


52


are of sufficient length, such that the locking pins


52


may be extended entirely through both the support structure sleeves


46


and the side posts of the vertically extending portion


26


of the frame structure


22


.




Left


54


and right


55


extending arms are movably mounted to the actuator system support structure


42


. The extending arms


54


and


55


may be made of steel or another similar strong and rigid structural material. The extending arms


54


and


55


are preferably mounted close together, parallel to each other, and perpendicular to the actuator system assembly support structure


42


and to the vertically extending portion


26


of the frame


22


. The movable extending arms


54


and


55


are movably mounted to the actuator system support structure


42


in a manner such that distal ends of the extending arms


54


and


55


are movable in an extending direction away from the frame


22


of the football training apparatus


20


in a forward direction and retractable toward the frame


22


of the football training apparatus


20


in a rearward direction. Moveable support of the extending arms


54


and


55


with respect to the actuator system assembly support structure


42


in this manner may be provided by a roller assembly support structure.




The roller assembly support structure may include a plurality of rollers


56


which are sized, shaped, and positioned so as to engage the extending arms


54


and


55


to provide movable support thereto in the manner described. Each of the rollers


56


is securely mounted to a roller support plate


58


, or other similar structure, which, in turn, is securely bolted or otherwise attached to the actuator system assembly support structure


42


. For example, as illustrated in

FIG. 5

, the roller support plates


58


may be securely bolted to the actuator system support structure cross pieces


44


. The rollers


56


, which may be made of a plastic or similar material, preferably are mounted on bearings to the support plates


58


to provide smooth roller movement. The roller support system should provide for smooth movement for the extending arms


54


and


55


with respect to the actuator system support structure


42


with minimal resistance.




Left


60


and right


61


strike pads are mounted on the distal ends of the corresponding left


54


and right


55


extending arms. The left


60


and right


61


strike pads are preferably sized and shaped, and the left


54


and the right


55


extending arms are properly spaced apart from each other, such that when the strike pads


60


and


61


are mounted to the distal ends of the extending arms


54


and


55


, with the distal ends of the extending arms


54


and


55


extended by the same amount, the left


60


and right


61


strike pads mimic the torso (shoulders and body) of an opposing football player. The strike pads


60


and


61


may be formed in a conventional manner as a covered pad of foam or other compressible material mounted to a rigid backboard plate


62


, made, e.g., of a rigid material such as metal or wood. The strike pad cover is preferably made of a wear and weather resistant material such as vinyl.




As illustrated in

FIGS. 6 and 7

, each strike pad


60


,


61


is preferably mounted to the corresponding extending arm


54


,


55


for rotational movement with respect thereto about a horizontal axis. An exemplary structure for mounting the right strike pad


61


to the distal end of the corresponding right extending arm


55


is illustrated in

FIGS. 6 and 7

. (The structure for mounting the left strike pad


60


to the corresponding left extending arm


54


may be identical.) A hinged bracket structure


64


may be used to attach the strike pad


61


to the distal end of the extending arm


55


. A part of the bracket


64


on one side of the hinge or pivot point


66


is attached to the backplate


62


of the strike pad


61


. The portion of the bracket


64


on the other side of the pivot point


66


is attached to the distal end of the extending arm


55


. The bracket


64


is preferably attached to the backplate


62


of the strike pad


61


near the top side thereof. Top


68


and bottom


69


strike pad stops are provided to limit the degree of rotational movement of the strike pad


61


about the pivot point


66


. The top


68


and the bottom


69


strike pad stops made be made, e.g., of rubber or some other compressible or semi-compressible material, and are preferably fixedly attached to the distal end of the extending arm


55


, e.g., by one or more strike pad stop bracket structures


70


. The top


68


and bottom


69


strike pad stops are preferably positioned by the bracket


70


attached to the distal end of the extending arm


55


so as to contact the back plate


62


of the strike pad


61


just above and just below the attachment point of the bracket


64


thereto, thereby to limit rotation of the strike pad


61


about the pivot point


66


.




In a down rotational position (as illustrated in FIG.


6


), the strike pad


61


is rotated such that the strike pad back plate


62


is in contact with the top strike pad stop


68


. In an up rotational position (as illustrated in FIG.


7


), a player contacting the front surface of the strike pad


61


drives the back plate


62


of the strike pad


61


against the bottom strike pad stop


69


. (A spring


71


, or other biasing mechanism, may be provided to bias the strike pad


61


into the down rotational position when not being contacted by a player, and to provide some resistance to rotation of the strike pad


61


.) The angle of rotation between the down position of the strike pad, as illustrated in

FIG. 6

, and the up position of the strike pad, as illustrated in

FIG. 7

, may be, approximately, 20°-30°. The strike pad stops


68


and


69


, therefore, in combination with the position of the extending arm


55


to which they are attached by the bracket


70


, establish a limited angle of rotation for the strike pad


61


such that the front surface of the strike pad


61


is oriented approximately 5° from vertical when in the down position and 35° from vertical when in the up position, as illustrated in

FIGS. 6 and 7

, respectively. The combined movement of the strike pad


61


upward and the extending arm


55


upward and rearward when struck simulates a player gaining leverage over an opponent. The strike pad


61


is initially positioned with a forward tilt to simulate a player in an attacking position. When the pad is engaged, it travels in an upward direction, mimicking the reversed arc line of travel that a lineman experiences while playing the game.




Left


72


and right


73


brake actuation mechanisms are provided on the actuator system assembly


40


in association with each of the left


54


and right


55


extending arms, respectively. (See

FIG. 5.

) Each of the left


72


and right


73


brake actuation mechanisms may include a brake actuation lever


74


or


75


, respectively. Each of the left


74


and right


75


brake actuation levers may be mounted to the actuator system assembly support structure


42


, e.g., to one of the support structure cross pieces


44


, by a corresponding bracket


76


or


77


. The brackets


76


and


77


may also provide support for one end of corresponding left


78


and right


79


brake cables. The left


74


and right


75


brake actuator levers are mounted to the corresponding left


76


and right


77


brackets for rotational movement with respect thereto. The brackets


76


and


77


position the brake actuator levers


74


and


75


such that the levers


74


and


75


will be contacted by the back plates


62


of the left


60


and right


61


strike pads, respectively, when the distal ends of the extending arms


54


and


55


to which the strike pads


60


and


61


are attached are pushed rearward into a fully retracted position. When the brake actuator levers


74


and


75


are engaged by the strike pads


60


and


61


in this manner, the levers


74


and


75


are moved with respect to the brackets


76


and


77


on which they are mounted. The brake actuator ends of the brake cables


78


and


79


are attached to the levers


74


and


75


such that the corresponding brake cables


78


and


79


are pulled when the strike pads


60


and


61


are moved so as to engage the brake actuator levers


74


and


75


. As will be discussed in more detail below, pulling of the brake cables


78


and


79


by the brake actuator levers


74


and


75


in this manner acts to release brake mechanisms mounted in the left


30


and right


31


rear wheels, respectively, thereby to release the normally engaged brake mechanisms to allow rotation of the rear wheels


30


and


31


and movement of the entire apparatus


20


.




A resistance mechanism biases the distal ends of the extending arms


54


and


55


, to which the strike pads


60


and


61


are mounted, in a forward direction, away from the front of the training apparatus


20


. The resistance mechanism resists movement of the distal ends of the extending arms


54


and


55


in a rearward direction toward the training apparatus


20


. Preferably, the resistance mechanism is adjustable, to provide variable resistance for athletes of different strength attempting to push the strike pads


60


and


61


rearward toward the apparatus


20


, thereby to engage the back plates


62


of the strike pads


60


and


61


against the brake actuator levers


74


and


75


to release the apparatus brake mechanisms. Such a variable resistance mechanism preferably allows more resistance to be added as a player's strength in driving the strike pads


60


and


61


rearward improves, and is preferably independently adjustable for each of the right and left sides of the apparatus. The variable resistance mechanism preferably provides a measurable quantity of resistance, such that a coach, trainer, or the player himself, may quantitatively monitor the player's improvement.




A preferred variable resistance mechanism may be implemented using elastic tension cords or bands


82


, as illustrated in

FIG. 4. A

plurality of elastic cords


82


are provided in association with each of the left


54


and right


55


extending arms. One end of the cords


82


(not shown in the Figures) may be fixedly attached to the actuator system assembly support structure


42


. For example, one end of the cords


82


may be fixedly attached to the support structure between plates


84


, by brackets, or by another similar structure, attached to the actuator system assembly support structure


42


, e.g., between the support structure cross pieces


44


(See FIG.


5


). The ends of the elastic tension cords


82


opposite the ends thereof which are fixedly attached to the support structure


42


may include loops


86


formed thereon. The looped ends


86


of the resistance cords


82


are adapted to be removably attachable to proximal ends of the extending arms


54


and


55


, e.g., by posts


88


or other structures provided extending from the proximal ends of the extending arms


54


and


55


. The cord posts


88


are sized and shaped, and the lengths of cords


82


are selected, such that the looped ends


86


of the cords


82


are easily placed around the posts


88


when the extending arms are in their fully extended position, and the looped ends


86


of the cords


82


are prevented from slipping off of the posts


88


as the extending arms


54


and


55


are driven rearward by a player or players contacting the strike pads


60


and


61


.




Each elastic tension cord


82


may provide a known amount of resistance, e.g., 150 pounds per cord. As a player's strength improves, by using the football training apparatus


20


of the present invention, additional cords


82


may be attached to each of the extending arms


54


and


55


, by placing the looped ends


86


of the desired number of cords around the corresponding cord posts


88


. Since the resistance provided by each cord


82


is known, a player's ability to drive the extending arms


54


and


55


rearward, until the strike pads


60


and


61


engage the corresponding brake actuator levers


74


and


75


, can be quantitatively determined from the number and resistance of the cords attached to the extending arms


54


and


55


during performance of the exercise. Additional posts


90


may be provided on the actuator system assemble support structure


42


, to which the looped ends


86


of cords


82


not attached to the posts


88


provided on the proximal ends of the arms


54


and


55


may be attached, to prevents such cords


82


which are not currently in use from interfering with operation of the actuator system


40


.




A more detailed view of an exemplary end of one of the handles


34


mounted to the rear of the frame structure


22


is illustrated in FIG.


8


. (The left rear handle


34


is shown in

FIG. 8

, the right rear handle


35


may be implemented similarly.) The rear handle


34


may preferably include a grip


92


, which may be attached to or formed on the end of the handle


34


. The grip


92


may be formed in a conventional manner of a compressible or semi-compressible material such as plastic, foam, or rubber. A hand brake release mechanism


94


is preferably mounted on the handle


34


near the grip


92


end thereof. For example, the brake release mechanism


94


may include a hand brake release lever


96


mounted for rotational movement to the handle


34


at a pivot point


98


. A hand brake release cable


100


is attached to an extending portion


102


of the brake release lever


96


. The extending portion


102


of the hand brake release lever


96


operates as a cam such that as the hand brake release lever


96


is rotated about the pivot point


98


, toward the handle


34


, the extending portion


102


of the brake lever operates to pull the band brake release cable


100


. As will be discussed in more detail below, the hand brake release cable


100


is coupled to a brake mechanism in the left rear wheel


30


, to release the normally engaged braking mechanism therein when the brake cable


100


is pulled by actuation of the hand brake release lever


96


. Preferably, separate hand brake release mechanisms


94


are provided on each of the left


34


and right


35


rear handles attached to the rear of the frame structure


22


, thereby to operate independently brake mechanisms in each of the left


30


and right


31


rear wheels, respectively. The hand brake release mechanism


94


is preferably positioned on the handle


34


such that hand brake release lever


96


may be easily operated by an individual grasping the handle


34


by the grip


92


portion thereof.




A brake mechanism associated with the left rear wheel


30


of the exemplary embodiment of a football training apparatus


20


in accordance with the present invention being described will now be described in additional detail with reference to

FIGS. 9

,


10


and


11


. (An independently operated braking mechanism of the same type may be employed for the right rear wheel


31


as well.) The rear wheel


30


may be mounted on a rotatable wheel drum


104


which, in turn, is mounted to the frame structure


22


, specifically, to the horizontal base portion


24


of the frame structure


22


, via the axle assembly


32


. The axle assembly


32


includes a bearing support structure for an axle supporting the wheel drum


104


, which allows free and smooth rotation thereof and, therefore, of the wheel


30


attached to the drum


104


. A cam type brake pad (not shown) is disposed within the wheel drum


104


adjacent an inner peripheral surface thereof. The brake pad within the wheel drum


104


is couple by a mechanism


106


to a lever


108


such that when the lever


108


is moved in a first direction the brake pad within the wheel drum


104


is pressed against the inner peripheral surface of the wheel drum


104


to prevent rotation thereof. In this state, the brake mechanism is said to be engaged. When the lever


108


is moved in an opposite second direction, the brake pad is pulled away from the inner peripheral surface of the wheel drum


104


, thereby allowing free rotation of the wheel drum


104


. In this state, the brake mechanism is said to be released.




A spring


110


, or other biasing mechanism, is preferably attached to an end of the lever


108


opposite the end thereof which is coupled to the mechanism


106


. The spring


110


, or other mechanism, biases the lever


108


in the first direction, such that the braking mechanism is maintained in a normally engaged state. (Note that the end of the spring


110


which is not attached to the lever


108


may be attached in a fixed position to an extending portion


112


of a bracket attached to the horizontal base portion


24


of the frame structure


22


. The spring end is shown detached from this bracket


112


in

FIGS. 9 and 10

.)




As illustrated in

FIG. 9

, the brake cables


78


and


100


, from the brake actuation mechanism


72


in the actuator system assembly


40


and the hand brake release mechanism


94


mounted on the rear handle


34


, respectively, are coupled to the same end of the lever


108


as the biasing spring


10


. The brake cables


78


and


100


are attached to this end of the lever


108


so as to operate against the operation of the biasing spring


110


when the cables


78


or


100


are pulled by operation of the brake actuator lever


74


or hand brake release lever


96


, as discussed previously. If either the brake actuator lever


74


in the brake actuation mechanism


72


or the hand brake release lever


96


is actuated, corresponding brake cable


78


or


100


will pull the lever


108


against the bias of the spring


110


in the second direction, thereby releasing the brake mechanism to allow free rotation of the wheel drum


104


and the rear wheel


30


attached thereto. Thus, either rear wheel


30


or


31


may be released from a state where the braking mechanism is normally engaged to prevent rotation of the wheel by either driving the corresponding strike pad


60


or


61


rearward so as to engage the corresponding brake actuator lever


74


or


75


, or by operation of the hand brake release lever


96


provided on either of the left


34


or right


35


rear handles. When both the brake actuator lever


74


or


75


and brake release lever


96


are released, the biasing spring


110


will pull the lever


108


in the second direction, thereby returning the brake mechanism (in either the left


30


or right


31


rear wheel) to the normally engaged state, thereby preventing rotation of the rear wheels


30


and


31


and, therefore, movement of the football training apparatus


20


.




A football training apparatus


20


in accordance with the present invention may be used in many ways as a functional strength machine to increase a player's strength and endurance, particularly as specifically applied to blocking. To use the apparatus


20


, the apparatus


20


is positioned on a surface which may be indoor or outdoor, grass, artificial turf, etc. The height of the actuator system assembly


40


with respect to the vertically extending portion


26


of the frame structure


22


is selected such that the strike pads


60


and


61


are at an appropriate height for a player


112


who will be using the apparatus


20


. The height of the actuator system assembly


40


may be adjusted in the manner described above, by sliding the sleeve ends


46


of the actuator system assembly support structure


42


either up or down to an appropriate position on the side posts of the vertically extending portion


26


of the frame


22


until the strike pads


60


and


61


are at the desired height and the apertures


48


in the support structure end sleeves


46


are aligned with corresponding apertures


50


in the side posts of the vertically extending portion


26


of the frame


22


. The lock pins


52


are then extended through the aligned apertures


48


and


50


in the actuator system assembly support structure end sleeves


46


and the side posts of the vertically extending portion


26


of the frame


22


, thereby to lock the actuator system assembly


40


into the desired position. A selected number of elastic tension cords


82


are attached to each of the left


54


and right


55


extending arms, by attaching the looped ends


86


of the selected number of cords


82


to the attachment posts


88


formed at the proximal ends of the extending arms


54


and


55


. An appropriate number of tension cords


82


, providing an appropriate degree of resistance force to movement of the extending arms


54


and


55


in a rearward direction, are selected as appropriate for the strength of the player


112


using the device.




The player


112


may then drive forward from a standing or down or set position, pushing on the strike pads


60


and


61


with each arm, thereby pushing the strike pads


60


and


61


into the up position and driving the extending arms


54


and


55


rearward, against the resistance force provided by the tension cords


82


. With the brakes in the rear wheels


30


and


31


of the apparatus


20


normally engaged, the football training apparatus


20


will not move until the extending arms


54


and


55


are driven rearward to the point where the strike pad back plates


62


engage the brake actuation mechanisms


72


and


73


to release the rear brake mechanisms. As long as the player


112


maintains sufficient force applied to the strike pads


60


and


61


, the brake mechanisms will remain released, and the apparatus


20


can be pushed in a rearward direction.




This type of exercise involves numerous functional strength aspects of training. Grip strength is required to kick the strike pads


60


and


61


into the up position. Pressing strength is required to engage the strike pads


60


and


61


against the brake actuation mechanisms


72


and


73


by pushing the extending arms


54


and


55


rearward against the resistance provided by the elastic tension cords


82


. Leg drive and strength are required to move the entire apparatus


20


once the brake mechanisms have been released. Stabilizer strength is required in all aspects of the machine's use. If only one of the strike pads


60


and


61


is pushed rearward sufficiently to engage the corresponding brake actuation mechanism


72


or


73


, one of the rear wheels


30


or


31


will remain immobile, and the apparatus


20


will veer sideways, rather than being moved straight backward. This simulates an opposing player evading a block which is not evenly applied.




Two players may use the football training apparatus


20


of the present invention for practicing combo or deuce blocking techniques. For such an exercise, each h player strikes one of the strike pads


60


and


61


. Both players must effectively drive the extending arms


54


and


55


rearward against the provided resistance to engage the brake actuation mechanisms


72


and


73


for the apparatus


20


to be pushed straight rearward. The apparatus


20


will move straight backward only if the maneuver is executed and maintained with proper coordination.




A coach or trainer


114


may position himself to the rear of the apparatus


20


to operate the hand brake release mechanisms


94


mounted on the rear handles


34


and


35


of the apparatus


20


, while a player


112


or players execute a block against the strike pads


60


and


61


at the front end of the apparatus


20


. The coach or trainer


114


may selectively release either or both of the left or right rear wheel brake mechanisms using the hand brake release levers


96


, to release either one or both of the rear wheels


30


or


31


before the strike pads


60


and/or


61


are engaged against the brake release mechanisms


72


and


73


. This simulates an opposing player responding to the player's block, to which the player being trained must respond appropriately.




A player


112


may also position himself behind the apparatus


20


, grasp the apparatus by t he rear handles


34


and


35


, release the brake mechanisms using the hand brake release levers


96


, and push the entire apparatus


20


from the rear. Thus, the apparatus


20


can be used as a strength and speed developer by pushing the machine from the rear side thereof, without engaging the strike pads


60


and


61


.




For all of the applications described, weight plates


38


may be loaded onto the stanchions


36


provided on the frame


22


to accommodate athletes of various strength levels and/or to simulate opposing players of various strength levels and/or weight.




A football training apparatus


20


in accordance with the present invention provides a quantitative functional strength machine. An amount of resistance provided against moving the extending arms


54


and


55


rearward and an amount of weight added to the apparatus


20


are both variable and quantitative. The resistance force required to drive the strike pads


60


and


61


rearward sufficiently to allow the apparatus


20


to be moved, the weight added to the apparatus


20


, and the distance the apparatus


20


is driven rearward or forward in a straight line by the player


112


can all be maintained to provide quantitative measures of a player's progress. Thus, a football training apparatus


20


in accordance with the present invention may be used as both a training tool and as a valuable functional rehabilitation tool. The apparatus


20


of the present invention will enable athletic trainers to evaluate quantitatively an athlete's progress and develop confidence prior to returning to drills and play.




It should be noted that the present invention is not limited to the particular exemplary applications and embodiments illustrated and described herein, but embraces all variations thereof which come within the scope of the following claims. For example, although it is preferred that a football training apparatus have separate independently operable extending arms


54


and


55


, strike pads


60


and


61


, and corresponding brake mechanisms, a football training apparatus in accordance with the present invention may be implemented with a single strike pad, extending arm, and brake mechanism. Furthermore, a football training apparatus in accordance with the present invention may be mounted on a sled or track rather than on wheels. In such a case, a braking mechanism preventing movement of the apparatus frame along the track or with respect to the ground may be employed.
