Definitions
- This invention relates to the field of training aids for batting a ball, and especially to devices for training the foot positions and body movements for batting a ball such as a baseball or softball.
- bat swing training aids have been devised for softball and baseball. Some of these include plates or mats placed on the ground beside a home plate, with foot placement indications for an address stance and swing stride. These aids vary in emphasis, mode of enforcement, intended result, safety, and other factors. However, none of them combines an ideal training result with safety, convenience, and practicality in the same way and to the same degree as the present invention.
- a product called “stride guide” is a flat plate with foot placement and stride indicators and a rotating disk for the ball of the back foot. It has a raised edge behind the disk to enforce lifting of the back heel, thus shifting the user's weight forward. It has other raised edges to limit the stride of the lead foot.
- it does not require the user to step with the lead foot, rather than slide, it does not physically set both feet in toe alignment for the address stance, it does not physically align the lead foot perpendicularly to the pitch, it does not physically set the address stance width, it does not retain the back foot, and it does not limit the pivot range of the back foot.
- the present inventor feels that physical enforcement of address stance and stepping into the swing provides more definitive training and faster coaching than visual indicators alone, and that these physical enforcements make a stronger impression on a user's “muscle memory”. She also feels that physical limits on the back foot pivot range are important, both for training and safety,

Abstract
A device for practicing an address stance and ball-hitting motion in a sport such as softball. A batter stands on a step plate (30) and a swivel plate (31) mounted on a flat base (12). The plates have adjustable separation, and align the user's feet using toe stops (36). The step plate (30) has foot guards (34) that force the user to step towards the pitch. The swivel plate (31) rotates about a vertical axis, and has foot-retaining straps (38, 39) that allow the heel to lift. Swivel stops (18, 20) limit the rotation range between address alignment and a safe maximum swivel. The user learns to step toward the pitch and swivel the back foot while swinging the bat, turning the body, and shifting weight toward the pitch. The foot plates (30, 31) are reversible on the base (12) for right or left-handed use.
Description
- This application claims the benefit of U.S. provisional application 60/671,608, filed Apr. 15, 2005 and U.S. provisional application 60/679,616, filed May 10, 2005
- This invention relates to the field of training aids for batting a ball, and especially to devices for training the foot positions and body movements for batting a ball such as a baseball or softball.
- Numerous bat swing training aids have been devised for softball and baseball. Some of these include plates or mats placed on the ground beside a home plate, with foot placement indications for an address stance and swing stride. These aids vary in emphasis, mode of enforcement, intended result, safety, and other factors. However, none of them combines an ideal training result with safety, convenience, and practicality in the same way and to the same degree as the present invention.
- For example, a product called “stride guide” is a flat plate with foot placement and stride indicators and a rotating disk for the ball of the back foot. It has a raised edge behind the disk to enforce lifting of the back heel, thus shifting the user's weight forward. It has other raised edges to limit the stride of the lead foot. However, it does not require the user to step with the lead foot, rather than slide, it does not physically set both feet in toe alignment for the address stance, it does not physically align the lead foot perpendicularly to the pitch, it does not physically set the address stance width, it does not retain the back foot, and it does not limit the pivot range of the back foot.
- The present inventor feels that physical enforcement of address stance and stepping into the swing provides more definitive training and faster coaching than visual indicators alone, and that these physical enforcements make a stronger impression on a user's “muscle memory”. She also feels that physical limits on the back foot pivot range are important, both for training and safety,

FIG. 6 is a sectional view taken along section line 6-6 ofFIG. 3 . -
FIG. 7 is a top view of left and right-handed configurations of the device relative to a home plate, with an extended lead portion of base. - The inventor recognized that a better training aid would be useful in instructing softball and baseball users during batting practice to align their feet in the address stance, to avoid putting their feet too far apart, to lift the back heel, and to step toward the pitcher and shift their weight while swinging the bat. She devised a convenient and practical device for this purpose. In this description “front” or “forward” means toward the ball pitcher, “back” means away from the ball pitcher. Gender-specific pronouns are used for convenience only, and are intended to include both genders.
- The drawings illustrate an embodiment of a device for training the foot positions and body motions for batting a ball such as a baseball during the address stance, swing, and follow-through. It teaches proper foot orientation and stance width, swing stride, shifting of body weight, and proper back foot pivot. It comprises a
base plate 12 withanchor holes 14 forground anchors 15. Astep plate 30 for the lead foot comprises atraction surface 32, a raisedtoe stop 36, and two raisedfoot guards 34. Thestep plate 30 is mounted to thebase plate 12 at a selectable position provided bypegs 17 inalternate peg holes 16 as seen inFIG. 5 . Aswivel plate 31 for the back foot comprises atraction surface 32, a raisedtoe stop 36, andfoot restraint straps swivel plate 31 is mounted on thebase plate 12 by abearing 42 that allows rotation of theswivel plate 31 about a vertical axis. Thebearing 42 may be recessed in thebase plate 12 as inFIG. 6 so that the top surfaces of thestep plate 30 and theswivel plate 31 are at approximately the same height. As an example of bearing 42 a ring of ball bearings captured between two race plates can be used. Thebase plate 12 may be divided in half along ahinge line 28 connected by ahinge 26 for compact folding. It may further comprise ahandle 29 on each half for convenient carrying of the folded device. Thehandles 29 may be on the ends of thebase plate 12, as shown, or on other parts of the edge. -
FIGS. 1 and 3 show aswiveled position 44 of theswivel plate 31 that occurs during a batter's swing. The swivel range is limited byswivel stops stop pegs 19 are inserted in a selected two of thestop holes swivel stop holes hole 18 stops theswivel plate 31 in alignment with thestep plate 30 for the address stance. The peg inhole 20 stops the swivel during the swing. Swivelstop 20 provides a predetermined swivel angle such as 40 degrees. Optionally, a series of stop holes 20 (not shown) or another adjustable stop means (not shown) can be provided so the user can select a swivel angle within a range such as 20-90 degrees, for both hitting and bunting practice. - The
step plate 30 is adjustably mounted so users know where and how to begin their address stance. This prevents them from starting with their feet too far apart. A series of stancewidth adjustment holes 16 may be provided on thebase plate 12. Thestep plate 30 may have a bottom surface with mountingpegs 17 extending downward for insertion intoselected adjustment holes 16 as inFIG. 5 . This allows thestep plate 30 to be mounted on the base plate in a position that provides a natural stance for the user, such as approximately shoulder width apart from theswivel plate 31. - The length of the baseplate(s) may be any selected length, with both halves being of equal or of unequal length as measured from the hinges.
FIG. 7 shows a version of this device with abase 12 with one half that is larger in the forward direction. This extension provides extra space upon which the lead foot can step during the swing, as shown byfootprints 46. The base may be asymmetric about thehinge 28, as shown inFIG. 7 . Twohandles 29 can be provided as shown that are equidistant from the hinge-line 28 at approximately a balance point when the base is folded. This brings the handles together in the folded position of the base for easy carrying, so that a latch is not needed to maintain the folded position.FIG. 7 shows a right-handed configuration 48 and left-handed configuration 50 of the device relative to ahome plate 52. - To use this device a user puts her back foot, which is the foot furthest from the pitcher into the
swivel plate 31 up to thetoe stop 36. Then she adjusts thetoe strap 38 across the foot, and adjusts theankle strap 39 over the foot and around the ankle. This retains the foot on theswivel plate 31 while allowing the heel to rise during the swing. The user puts her lead foot on thestep plate 30 with her toe against thetoe stop 36 and the leading side of the foot against afoot guard 34. The user is now standing on the two plates with her feet aligned with each other as shown byfootprints 46 ofFIG. 7 . - The user takes an address stance for swinging a bat at a pitched ball. The user steps forward towards the pitch, shifts body weight toward the pitch, lifts the back heel, and twists hips and shoulders toward the pitch, causing the
swivel plate 31 to turn to its stop. Proper foot alignment is taught by placing one foot on the steppingplate 30 and one foot on theswivel plate 31. The user places each foot forward to therespective toe stop 36. This teaches the user to align the feet evenly. The front foot is placed against the forward-most foot guard so the foot is perpendicular to the pitch. The user's back foot is strapped on to the swivel plate with a toe strap across the toe area and an ankle strap around the ankle. The proper address stance width is important so the user does not overstep the swing. Stance width is set by adjusting the steppingplate 31 to the natural stance of the user by mounting the stepping plate pegs 17 in a selected pair ofholes 16. - Once the user has proper placement of her feet on the stepping
plate 30 and theswivel plate 31, she is ready to begin her swing. The user will step over thefoot guard 34 on the steppingplate 30, causing her weight to shift forward toward the ball. This will happen naturally when she steps, since thebase plate 12 is lower than the stepping plate. It is important for the user to learn to step forward and not to slide the front foot forward, in order to ensure proper weight shift to the front leg. Thefoot guard 34 requires the user to lift the front foot a predetermined distance to clear thefoot guard 34, thus training the user not to slide the foot. The base can be made long enough to receive the lead foot after it steps forward off of the stepping plate. The user's back foot stays against thetoe stop 36. The heel of the back foot is raised, shifting weight to the ball of the foot as the user turns the foot and theswivel plate 31. - This device is designed for practical manufacture. All
plates step plate 30 and theswivel plate 31 can be formed in the same mold, includingfoot guards 34 on both plates, to reduce tooling cost. The materials for the construction of the various structural members of the device may be plastic, wood, metal, fiberglass, or other material having the required strength and preferably lightweight for easy portability. The peg holes 16, 18, 20, 22, 24 in the base plate may be lined with sleeves (not shown) to enable the pegs to be removed and replaced repeatedly without damaging thebase plate 12. - Holders for the
anchors 15 may be provided on thebase plate 12. For example,depressions 13 can be provided in the base 12 as shown inFIGS. 1, 3 , and 4 to frictionally grip and hold the anchors in a stored position. Spring clips or other known holders can also be used. The anchors may haveloops 41 as shown inFIG. 2 for easy manual pulling of the anchors from the ground. In this case, the anchors can be stored on thetoe strap 38, without need for other holders. - The
step plate 30 has two lateral adjustment pegs 17 on the bottom, a non-skidupper surface 32, atoe stop 36, and a raisedfoot guard 34 on each side. Onefoot guard 34 is used for right-handed hitters and the other is used for left-handed hitters. To convert between right and left-handed hitters thestep plate 30 is lifted from thebase 12, rotated 180 degrees, and reset in the adjustment holes 16. - The
swivel plate 31 has atoe stop 31 withholes 40 for attaching theankle strap 39. Thetoe strap 38 can be attached to the swivel plate as shown. Optionally twofoot guards 34 can be provided on theswivel plate 31 as on thestep plate 30 to prevent the back foot from slipping off theswivel plate 31. In this case, thetoe strap 38 can be attached to the foot guards. To convert theswivel plate 31 between right-handed and left-handed hitters, the stop pegs 19 are removed, and the swivel plate is rotated 180 degrees, then the stop pegs 19 are placed into stop holes 18 and 20 for right-handed hitters or holes 22 and 24 for left-hand hitters. Optionally, the stop pegs 19 may be provided in the form of captured spring-loaded buttons in all of the stop holes 18, 20, 22, 24, that toggle between an extended and retracted position. - The toe and ankle straps 38, 39 may be made of leather, fabric, plastic, or other appropriate material. The two ends of each strap should have the capability of being joined together and loosened to facilitate insertion and removal of the foot. The clasp for the straps may be a buckle, VELCRO brand fastener, cinch strap with ring, quick release buckle or simply a tie or some other appropriate clasp. The
ankle strap 39 may or may not be crossed over the top of the foot. - While various embodiments of the present invention have been shown and described herein, it will be obvious that such embodiments are provided by way of example only. Numerous variations, changes and substitutions may be made without departing from the invention herein. Accordingly, it is intended that the invention be limited only by the spirit and scope of the appended claims.
