Description
Background of the Invention
This invention relates to football training apparatus and more particularly to apparatus for training football players to maintain their legs spread a predetermined distance during blocking or tackling exercises.
A football player who executes a face block or a shoulder block and who maintains a wide stance is generally more stable and thus more difficult to knock down than he would be if he maintained his legs close together. When a lineman assumes his initial stance at the line of scrimmage prior to the start of the play, he generally assumes a stance in which his legs are spread a sufficient distance to effect a proper block. After the start of the play and initial contact with an opposing player, some linemen tend to bring their legs closer together and thus become unstable and more easily knocked down. It is important that a football player maintain a relatively wide stance during the entire blocking movement in order to obtain maximum blocking effectiveness.
Accordingly, it is an object of the present invention to provide football training apparatus which will teach a football player to maintain a relatively wide stance throughout an entire blocking or tackling exercise.
It is another object of the present invention to provide football training apparatus which will teach a football player a more stable stance when he is blocking or tackling an opposing player.
The present invention comprises a stance training member which is disposable between the legs of a football player and is adapted to be connected by a resilient cord to a football blocking sled mounting a chargeable pad, the cord being of such length that the player executing the block will straddle the stance training member when he is in position to engage the blocking pad.
It is important that the cord be resilient so that in the event a player inadvertently steps on the stance training member as the block is being executed, the blocking exercise is not interrupted as it would be if the cord was inelastic. With apparatus constructed according to the present invention, if a player inadvertently steps on the stance training member, forward movement of the stance training member is inadvertently interrupted although the sled and chargeable pad can continue moving forwardly. As soon as the player steps off the stance training member, the stance training member will be moved forwardly toward the sled to maintain its position between the football players legs so that the blocking exercise can continue until fully executed. Accordingly, it is an object of the present invention to provide a stance training member which is connected to a blocking sled via a yieldable member.
Other objects and advantages of the present invention will become apparent to those of ordinary skill in the art as the description thereof proceeds.
Summary of the Invention
A stance training device for a ground supported football training sled having a chargeable member which is movable forwardly when charged by a football player, a resilient member for connecting the stance training device to the sled for forward movement therewith but permitting the sled to move forwardly relative to the stance training device if a player inadvertently steps on the device as the chargeable member is moving forwardly.

Description of the Preferred Embodiment
Referring now more particularly to the drawings, a football blocking sled, generally designated S, is provided for training football players in the art of blocking and tackling.
The sled S is identical to the sled disclosed in applicant's U.S. Pat. No. 3,827,690 granted Aug. 6, 1974 which is incorporated herein by reference as though fully set forth herein. Generally, the sled S includes a ground engageable runner 12 mounting an upstanding blocking dummy support post 13. An impactable blocking dummy generally designated D, is mounted on the vertically disposed post 13 via a transversely extending post 14 telescopically received in a sleeve 16 mounted atop the post 13.
The apparatus disclosed heretofore is fully described in the aforementioned patent and will not be described in detail herein.
As described in the aforementioned patent, a football player will charge the blocking dummy D with either a face block or a shoulder block to forwardly move the dummy D in the direction of the arrow a. If a player impacts the dummy pad D with sufficient force, the entire sled S will forwardly move in the direction of the arrow a. The player continues to charge forwardly to move the dummy pad D and sled S forwardly to simulate moving an opposing player away from the play. It is important that a football player maintain a wide stance while he engages the dummy D throughout the entire blocking exercise.
To train the player in maintaining a wide base stance throughout a blocking exercise, stance training apparatus, generally designated 18, is provided and includes a ground supported, elongate stance training block generally designated 20, comprising rugged urethane foam of the self-skinning type which has an open cell inner core structure 22 and a micro-cellular structure 24 near the surface which presents a durable skin.
The block 20, which is generally trapezoidal in cross-section, has upwardly converging lateral sides 23 as well as upwardly converging front and rear ends 25 and 27 respectively. The block 20 is of such width that if a player straddles the stance training block 20 and maintains his feet on laterally opposite sides 23 of the block 20 his stance will have the proper minimum spread.
A nylon cloth 26, which extends the full length of the block 20, is bonded to the foam block 22 adjacent the lower surface thereof. When the stance training block 20 is manufactured, the nylon cloth 26 is placed at the bottom of a mold and the foam which is initially in a liquid state is injected into the mold and extruded upwardly through the nylon cloth 26. As the foam cures, it bonds to the cloth 26. As is illustrated in the drawing the forward end 29 of the cloth 26 projects forwardly beyond the forward end 25 of the block 20. A brass eyelet 31 is provided in the forward end of the nylon cloth 26 for receiving a hook 28 which is fixed to one end of an elastic or resilient tether cord 30 having a hook 32 at the opposite end connected to an eyelet 34 fixed to the front of the runner 12.
The self skinning foam comprising the block 20 is flexible, longlasting, will not splinter, tear or peel, but yet is soft enough to prevent turned ankles if a player inadvertently steps on the stance training block 20.
Operation
In operation, a football player assumes a charging stance in front of the sled S with his feet straddling the stance training block 20. As the football player charges forwardly and engages the blocking dummy D with his shoulders or face, he will propel the dummy pad D and the sled S forwardly in the direction of the arrow a. The elastic tether or cord 30 will forwardly draw the training block 20 with the sled S. To properly complete the blocking drill the player must maintain his feet on opposite sides of the block 20 throughout the entire forward movement of the sled. If the player inadvertently steps on the block 20 while the block is being executed, the elastic cord 30 will deform or stretch so that the sled can continue to move forwardly and the blocking exercise is not interrupted and the sled S can continue to move forwardly. When theplayer subsequently steps off the block 20, the elastic cord 30 will return the training block 20 forwardly toward the sled S so as to maintain the block 20 positioned between the players feet.
Alternate Embodiment
The stance training apparatus 18a in FIGS. 5 - 7 is similar in many respects to the stance training apparatus 18 illustrated in FIGS. 1 - 4 and generally similar parts will be identified with generally similar numerals followed by the letter a subscript. In the stance training apparatus 18a illustrated in FIGS. 1-4, the stance training block 20 is generally symmetrical.
In the stance training apparatus 18a, the forward end 36 of the stance training block 20a is upwardly, forwardly inclined as illustrated at 38 so that the block 20a will more easily negotiate irregular terrain. The front end 40 of the block 20a to is of substantially reduced vertical thickness and extends forwardly of the inclined portion 38 and in spaced relation with the surface being traversed. The lateral sides 42 of the front end 40 also forwardly converge as is best illustrated in FIG. 5. A grommet 31a is provided through the forward projection 40 to receive a draft hook 28a.
It is to be understood that the drawings and descriptive matter are in all cases to be interpreted as merely illustrative of the principles of the invention, rather than as limiting the same in any way, since it is contemplated that various changes may be made in various elements to achieve like results without departing from the spirit of the invention or the scope of the appended claims.
