Definitions
- the current invention is directed to a practice swing machine for baseball hitters; and more particularly to a practice swing machine that provides simultaneous hitting and power development for a batter.
- Conventional hitting machines come in many forms, but most of these machines only provide swing control training, i.e., that can teach a hitter how to make good contact with the ball, but not how to improve the power of their swing. Examples of these machines range from the simple ball holder disclosed in U.S. Pat. No. 2,772,882, to single point pivoting devices such as those disclosed in U.S. Pat. Nos. 3,550,938 and 5,601,286. The disclosures of each of these devices are incorporated herein by reference. A few machines do attempt to combine contact training with power training, such as those disclosed in U.S. Pat. Nos. 4,451,036; 4,655,452; and 5,226,645, the disclosures of each of which are incorporated herein by reference; however, to date these machines have not been able to successfully mimic the complex motion of a baseball swing.
- the swing arms are supported by a frame that provides at least one degree of freedom in defining the geometry of the arced swing target in relation to its surroundings.
- any of the following characteristics of the swing target may be adjusted including, the height from the ground, the distance from the frame to the hitter, the angle of the swing trajectory arc relative to a horizontal plane, the width of the swing trajectory arc, and the angle of the swing trajectory arc relative to a vertical axis normal to the ground.
- a plurality of resistance elements may be disposed on the inner surfaces of the opposing swing arms within the swing target gap to provide a level of resistance to the hitter.
- the level of resistance can be adjusted.
- the level of resistance may be adjusted by altering the position of the resistance elements relative to each other.
- interchangeable resistance elements made of different materials may be provided to allow for a variable resistance.
- the outer portion of the swing arms at the entrance to the swing trajectory arc gap may be padded with a resilient material to protect the device from errant swings.
- the frame of the machine may be collapsible and/or mounted on wheels to allow for the storage and transportation of the device.
- the invention is directed to a method of batting practice utilizing a customizable swing target as disclosed herein.
- FIG. 1 a is a top view of a batter in the process of swinging
- FIG. 1 c is a top view of an exemplary practice swing machine in accordance with the current invention.
- FIG. 2 is a perspective drawing of one exemplary embodiment of the current invention during use
- FIG. 3 a is a front view of the swing arms in accordance with one exemplary embodiment of the current invention.
- FIG. 3 b is a top view of the swing arms in accordance with one exemplary embodiment of the current invention.
- FIG. 4 is a rear perspective view of one exemplary embodiment of the current invention.
- FIG. 5 is a side view of one exemplary embodiment of the current invention.
- FIG. 6 is a front view of one exemplary embodiment of the current invention.
- FIG. 8 is a top view of one exemplary embodiment of the current invention.
- the current invention is directed to a practice swing machine that models the full arc of a batter's swing trajectory, providing both power and swing training in a consistent and controlled manner through the entire hitting zone.
- hitting zone “swing training”, and “power training” are defined as follows:
- swing training refers to a method of allowing a hitter to practice the accuracy of his swing, i.e., the location of the bat head within the hitting zone.
- power training refers to a method of providing some resistance within the hitting zone such that the hitter is required to exert extra force to swing the bat head through the hitting zone.
- FIG. 1 a As shown in FIG. 1 a , every hitter's swing describes an arc ( 1 ) centered about the hitter's body ( 2 ).
- the portion of the bat interacting with the training device inherently changes as the bat traces this arc, as shown by FIG. 1 b.
- the current invention is directed to a practice swing machine that provides an arced “training zone” that can be adjusted to mimic the precise arc of the hitter's own swing.
- the device of the current invention comprises a pair of opposing swing armatures that define a gap.
- the gap in turn takes the form of an arc or “swing arc” ( 4 ) that is designed to model the trajectory of a hitter's swing.
- the armatures are themselves supported by a frame that can be adjusted in any one of a number of degrees of freedom to allow for the movement of the armatures relative to one another, thereby allowing for the location and geometry of the swing arc to be customized to correspond to each individual hitter's swing.
- FIGS. 3 a and 3 b a front view of one embodiment of an arced swing target ( 20 ) in accordance with the current invention is provided in FIGS. 3 a and 3 b .
- the swing target ( 20 ) generally comprises a lower armature ( 16 ) and an upper armature ( 18 ) mounted in parallel along a generally horizontal axis (h) such that the inner surfaces of each armature cooperatively form a swing gap ( 19 ) through which the bat (b) passes during a swing.
- the armatures are maintained in position by a pair of upper and lower support arms ( 14 ) that adjustably fix the swing armatures ( 16 & 18 ) into position relative to one another.
- the inner surfaces of the swing armatures ( 16 & 18 ) can optionally be fitted with one or more resistance elements ( 21 ) such that the swing gap ( 19 ) is at least partially impeded by said elements.
- the resistance elements ( 21 ) can take any form and can be made of any material suitable to impede the movement of the bat (b) within swing gap ( 19 ).
- the frictional resistance elements take the form of spherical bodies formed of a resilient material such as rubber; however, other forms such as, for example, pyramids, flaps, squares, rods, etc. may be used.
- these elements may be made of other materials capable of repeated resilient deformation, such as, for example, plastics, fabrics, etc.
- the resilient members are formed of a felt coated rubber material.
- the resistance elements ( 21 ) shown in FIG. 3 a are static, it should be understood that the elements themselves could be made to move within the swing gap ( 19 ) to provide a variable resistance to the hitter's swing.
- the resistance elements could be designed to move orthogonal to the inner surface of the swing armatures such that the resistance elements could be extended into or retracted out of the swing gap ( 19 ) depending on the level of resistance desired by the hitter.
- a range of resilient elements having variable resistance factors could be supplied with the swing machine.
- the resilient elements would be removable such that the hitter could alter the resistance provided by the resistance elements by changing the resilient elements ( 21 ) mounted within the swing gap ( 19 ).
- FIG. 3 a shows the support arms ( 14 ) and the swing armatures ( 16 & 18 ) as fixed in a single position
- the support arms ( 14 ) or the swing armatures ( 16 & 18 ) may be designed to move independently to allow for the repositioning of the swing armatures both relative to one another and relative to the hitter.
- the swing armatures may be designed to allow the alteration of the curvature of the arc of the swing target ( 20 ) to better correspond to a hitter's swing.
- FIGS. 4 to 8 provide detailed diagrams showing some exemplary frame adjustments that may be incorporated into the current device.
- FIG. 4 provides a rear perspective view of the practice swing machine of the current invention.
- the upper and lower swing armatures ( 16 & 18 ) that define the swing gap ( 19 ) are held in place by upper and lower support arms ( 14 a & 14 b ).
- the upper and lower support arms are in turn interconnected to a base ( 22 ) that can take any form suitable for stabilizing the device against movement during use.
- the base ( 22 ) comprises to elongated leg elements ( 23 a & 23 b ) that engage either end of the lower support arm ( 14 b ).
- the swing armatures are mounted onto the support arms through a cooperative set of support connectors ( 14 a ′, 14 b ′, 16 ′ and 18 ′).
- the upper swing armature ( 18 ) is provided on its upper surface with a male connector ( 18 ′) that cooperatively and slidingly engages a female connector ( 14 a ′) on the upper support arm ( 14 a ).
- the lower swing armature ( 16 ) is provided on its lower surface with a male connector ( 16 ′) that cooperatively and slidingly engages a female connector ( 14 b ′) on the lower support arm ( 14 b ). Because the swing armatures are both slidingly engaged with their respective support arms, the swing armatures may be independently raised or lowered to adjust the height of the swing target or the width of the swing gap ( 19 ) as desired by the hitter. When the swing target is in the desired position the swing armatures may be locked into position by any standard locking mechanism, such as a spring loaded pin, screw, wire, frictional fitting, etc.
- FIG. 5 provides a side view of an exemplary embodiment of an adjustable practice swing machine in accordance with the current invention.
- the frame ( 12 ) may incorporate a number of different adjustment mechanisms, including vertical, horizontal and angular adjustments.
- the device could include a vertical swing armature adjustment mechanism ( 24 & 30 ), which would allow for the independent adjustment of the two swing armatures ( 16 & 18 ) relative to each other along a vertical axis.
- a vertical adjustment mechanism may take the form of two cooperatively engaged slidable members that interconnect the swing armatures ( 16 & 18 ) and the support arms ( 14 a & 14 b ).
- the frame may incorporate at least one independent horizontal adjustment mechanism to allow for the swing armatures ( 16 & 18 ) to be offset one from the other in the horizontal plane.
- a horizontal adjustment incorporates a support arm ( 14 a ) that is formed of two slidably cooperative pieces joined with a locking mechanism ( 32 ).
- the portion of the support arm ( 14 a ) interconnected with the swing armature ( 18 ) would slide within the body of the portion of the support arm interconnected with the base ( 22 ), thereby allowing for the upper and lower swing armatures ( 16 & 18 ) to be offset from each other in the horizontal plane.
- FIG. 5 only the upper support arm is shown to include such a horizontal adjustment mechanism, it should be understood that the lower support arm ( 14 b ) could be made horizontally adjustable in a similar manner.
- the frame could also be provided with a mechanism for adjusting the vertical alignment of the upper and lower support arms ( 14 a & 14 b ) relative to one another.
- the upper and lower arms ( 14 a & 14 b ) could be slidingly interconnected along their vertical axis ( 34 ) such that the upper arm could be retract within the lower arm.
- Such a mechanism would provide a mechanism for adjusting the overall vertical height of the practice swing machine, and would also provide a second mechanism for adjusting the vertical position of the swing target ( 20 ).
- the mechanism also contemplates adjustment mechanisms that would allow for the angular alignment of the components of the device.
- FIG. 5 mechanisms are shown that would allow for the independent rotation of the swing armatures ( 16 & 18 ).
- the swing armatures ( 16 & 18 ) would be joined to their relative connectors ( 16 ′ & 18 ′) through a locking pivot mechanism ( 26 & 28 ) such that the swing armatures could be rotated about their individual longitudinal axes.
- Such a mechanism would allow for the rotation of the plane defined by the swing gap ( 19 ) about its longitudinal axis ( 1 ).
- the practice swing machine may also be provided with a mechanism for adjusting the angle of the vertical axis of the frame ( 12 ).
- a mechanism for adjusting the angle of the vertical axis of the frame ( 12 ) comprises a pair of locking pivots ( 36 ) that interconnect the support armature ( 14 b ) to the base ( 22 ).
- the entire frame ( 12 ) could be pivoted about the horizontal axis of the base ( 22 ) to allow for the adjustment of the angle of the longitudinal axis ( 1 ) of the swing target relative to the ground.
- any of the above adjustment mechanisms could be provided with a locking mechanism, such as, for example, a spring loaded pin, screw, wire, frictional fitting, etc., such that once the adjustment mechanism is in a desired position the mechanism could be locked against further unwanted movement.
- a locking mechanism such as, for example, a spring loaded pin, screw, wire, frictional fitting, etc.
- the practice swing machine could be at least partially collapsed to provide easier transport of the machine.
- the machine may be collapsed in any suitable manner, in the embodiment shown in FIG. 7 the upper frame ( 38 ) is pivoted about pivot point ( 38 ) to fold flat against the base members ( 22 ) forming a compact machine that can be more easily moved.
- wheels could be provided on one or both of the base members ( 22 ) to allow for easy transport of the device.
- the swing target ( 20 ) and support arms ( 14 ) could be pivoted about a pivot point ( 40 ) mounted on one of the two base members ( 23 ).
- wheels could be mounted on the lower base member to allow for easy transport of the collapsed device.
- the device and its individual components can be made of any material that would provide sufficient strength and durability for the intended purpose of the device.
- Some exemplary materials include metals, such as aluminum or steel, plastics, wood, and composites.
- individual components may be made of different materials based on the material properties required to accomplish the intended use of those components.
- the current application is also directed to a method of simultaneously training a hitter to have better swing accuracy and power by providing a fully adjustable practice swing machine that incorporates a swing target that provides a consistent level of swing interaction along the trajectory of the hitter's swing within the desired hitting zone.
