Abstract
A batting practice device comprising a resiliently flexible and elongate retaining rod, a target member coupled to a distal end of the elongate retaining rod, and a clamping structure for clamping a proximal end of the elongate retaining rod to an environmental structure, such as chain link fence. The target member may be coupled directly to the distal end of the elongate retaining rod as by having the elongate retaining rod pass through a bore hole in the target member. A fixed or selectively removable ball stop may retain the target member on the elongate retaining rod. The clamping structure may incorporate a first clamping block and a second clamping block and a threaded clamping nut that selectively presses the blocks together. The first and second clamping blocks can have first and second elongate clamping furrows for engaging adjacent strands on a chain link fence. Pins may project from the first clamping block to engage bore holes in the second clamping block to prevent relative rotation of the first clamping block relative to the second clamping block. The retaining sleeve can be tubular so that the proximal end of the elongate retaining rod can pass therethrough to be selectively fixed in place.
Description




FIELD OF THE INVENTION




The present invention relates generally to sporting implements. Stated more particularly, this patent discloses and protects a batting practice device for aiding a ball player in practicing and improving his or her batting ability and for allowing a player to warm up prior to a game or a given at bat.




BACKGROUND OF THE INVENTION




Becoming a better hitter is certainly an object of every baseball and softball player. Similarly, nearly all players in such sports typically find it advantageous to warm up prior to each game. Still further, most players seek to take a number of practice swings immediately prior to a given at bat to refresh muscle memory, to warm up, and, possibly, to quell any nerves that might interfere with proper batting.




Unfortunately, even during practice sessions, it is often difficult for a batter to get as much practice as he or she might desire or, indeed, require. With this, a hitter may be deprived of the practice needed to become truly proficient. Although pitching machine have been disclosed that may be useful tools for enabling a hitter to get more of the practice that is essential to developing a proper hitting technique, like an actual human pitcher, use of such machines or a human pitcher require not only the batting practice pitcher or the pitching machine, but they also require an open field and persons to shag the batted balls. These requirements render such practice methods problematic for an individual user and particularly impracticable for a batter while a game is underway. Accordingly, it will be appreciated that it is desirable to provide a means for a ball player to practice to practice batting in a limited space without interfering with non-practice areas and without requiring the retrieval of a ball with each practice swing.




Advantageously, as one knowledgeable in the art will be aware, a number of inventors have sought to provide batting practice devices that meet the aforementioned needs of ball players. These devices are of undisputed utility, and they have undeniably improved batters' abilities by allowing extended, individual practice sessions. They have also enabled unobtrusive opportunities for a batter to warm up prior to a game or a given at bat.




Unfortunately, though, the devices of the prior art suffer from a number of disadvantages that together make clear that there remains a need in the art for an improved batting practice device. For example, many batting practice devices of the prior art are complex in construction whereby they are susceptible to malfunction and breakage and are relatively expensive and difficult in manufacture, installation, and repair. By way of example, many prior art batting practice devices provide a target member for being struck that is retained at a first end of a tether that, in turn, is retained by its second end by a retaining structure. In these devices, the tether can become entangled, a swiveling structure can become worn or broken, the swinging target member can strike the user or an observer, and the tether can break thereby creating danger, expense, and delay. Furthermore, many prior art devices require tools and demand a significant expenditure of time and effort for their installation. With this, use of the devices can be delayed and even discouraged.




With these things in mind, it becomes clear that a batting practice device that overcomes the deficiencies of its predecessors while providing a number of heretofore unrealized advantages thereover would represent a marked advance in the art.




SUMMARY OF THE INVENTION




Advantageously, the present invention sets forth with the broadly stated object of providing a batting practice device that solves each of the problems left by the prior art while providing a number of heretofore unrealized advantages thereover.




A most basic object of the invention is to provide a batting practice device that enables a ball player to practice batting in a limited space without a need for other players or assistance.




A further object of the invention is to provide a batting practice device that is exceedingly simple and durable in construction.




Still another object of the invention is to provide a batting practice device that can be coupled to an environmental structure, such as a fence, in a rapid manner without a need for tools.




These and further objects and advantages of the present invention undoubtedly will be obvious both to one who has an opportunity to enjoy the use of an embodiment of the present invention and to one who reviews the present disclosure.




In carrying forth these objects, a most basic embodiment of the invention essentially comprises a batting practice device for enabling a user to practice batting and to warm up prior to a game or a given at bat. The batting practice device is founded on an elongate retaining rod, a target member that is coupled to a distal end of the rod, and a means for supporting the proximal end of the rod. Advantageously, even under this most basic embodiment, a ball player can practice batting and can warm up prior to a game or a given at bat by striking the target member with a striking implement.




Preferably, the target member will be affixed directly to the distal end of the elongate retaining rod without the intervention of any tether or other structures that have been employed in the prior art. Furthermore, the preferred elongate retaining rod will be resiliently flexible whereby the target member and the elongate retaining rod will tend to deflect in response to an impact by a striking implement and whereby the target member and the elongate retaining rod will tend to return approximately to an initial position after an impact by a striking implement. Still further, a most preferred elongate retaining rod will be formed from a strand of wire rope coated with a plastic sheath. With this, the elongate retaining rod will demonstrate exemplary durability while not tending to damage a striking implement with which the batting practice device is struck.




The preferred target member will have a bore hole therethrough, and the elongate retaining rod will be received within the bore hole. To retain the target member on the elongate retaining rod, a ball stop will be disposed at the distal end of the elongate retaining rod. In such a case, the target member can have a countersunk bore hole portion surrounding the bore hole whereby the ball stop can be counter sunk within the countersunk bore hole portion and whereby damage to a striking implement by the ball stop is prevented. The ball stop can be fixed to the distal end of the elongate retaining rod or it can be removably coupled, as by a threaded fastener, so that the ball stop and the target member can be selectively removed from the elongate retaining member. With this, the target member can be removed and replaced when damaged or worn.




The means for supporting the proximal end of the rod may be in the form of a clamping structure for clamping the batting practice device to an environmental structure whereby the batting practice device can be employed in a wide variety of locations. In such a case, the clamping structure could comprise a first clamping block and a second clamping block that cooperate with a means for selectively pressing the clamping blocks together. With this, the first and second clamping blocks can be disposed to sandwich and clamp about an environmental structure.




In certain embodiments, the first and second clamping blocks may be disposed on a retaining sleeve. Also, the means for selectively pressing the first and second clamping blocks may be a clamping nut that is disposed on the retaining sleeve in cooperation with threads that are also disposed on the retaining sleeve. Preferably, a clamp stop will be fixed to the retaining sleeve so that the first and second clamping blocks can butt thereagainst when they are pressed together by the clamping nut. The preferred clamping blocks will include aligned first and second elongate clamping furrows for engaging adjacent wire strands on a chain link fence. Furthermore, pins and bore holes may be disposed in alignment of the clamping blocks to interengage with one another to prevent relative rotation of the first clamping block relative to the second clamping block.




The retaining sleeve may be tubular so that the proximal end of the elongate retaining rod can pass therethrough. In such a case, the device may include further a means for selectively fixing the elongate retaining rod relative to the retaining sleeve. Of course, this means could take a variety of forms. However, one preferred means could comprise a clamping member for selectively compressing about the elongate retaining rod. With this, the elongate retaining rod could be readily slid relative to the retaining sleeve to allow an adjustment of its effective length or to permit replacement of a damaged rod.




With a plurality of embodiments of the present invention for a batting practice device described, one will appreciate that the foregoing discussion broadly outlines the more important features of the invention merely to enable a better understanding of the detailed description that follows and to instill a better appreciation of the inventor's contribution to the art. Before an embodiment of the invention is explained in detail, it must be made clear that the following details of construction, descriptions of geometry, and illustrations of inventive concepts are mere examples of the many possible manifestations of the invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




As is the case with many inventions, the present invention for a batting practice device is subject to a wide variety of embodiments. However, to ensure that one skilled in the art will fully understand and, in appropriate cases, practice the present invention, certain preferred embodiments of the broader invention revealed herein are described below and shown in the accompanying drawing figures.




With this in mind and looking more particularly to the accompanying figures, a preferred embodiment of the present invention for a batting practice device is depicted generally at


10


in FIG.


1


. As

FIG. 1

shows, the batting practice device


10


incorporates an elongate and flexible retaining rod


14


with a proximal end and a distal end. Disposed at the distal end of the flexible retaining rod


14


is a target member


12


, which in this case is a standard baseball or softball. A standard baseball or softball is preferred as it most closely simulates the sensation of impact under actual playing conditions. However, the target member


12


could certainly be of a variety of types, such as a rubber ball, a plastic ball, any shape or size ball, or a member of substantially any other material. Of course, the target member


12


need not be a ball. The target member


12


could readily be employed in the shape of a puck or any other target for being struck. The only requirement is that the target member


12


be capable of withstanding an impact from a striking implement, such as a baseball or softball bat (not shown).




Similarly, the flexible retaining rod


14


certainly could be formed from a wide variety of materials. Of course, as its name would suggest, the flexible retaining rod


14


should be formed from a resiliently deformable material that will allow the batting practice device


10


to exhibit resilient deformation when the target member


12


is struck by a striking implement. For example, the flexible retaining rod


14


could be formed from a wire rope or any similarly resiliently deformable material. However, it is presently preferred to form the flexible retaining rod


14


from a strand of wire rope coated with a plastic sheath.




The target member


12


is retained at the distal end of the flexible retaining rod


14


by a ball stop


18


, which in this embodiment comprises a disk that is fixed to the distal end of the flexible retaining rod


14


. The ball stop


18


could be retained in place by welding or any other suitable mechanism. Alternatively, the ball stop


18


could be retained as by a threaded fastener


56


that passes through the ball stop


18


and into the distal end of the flexible retaining rod


14


. With this, the ball stop


18


and the target member


12


can be readily removed so that the target member


12


can be replaced, if necessary, when worn or damaged.




As

FIG. 2

shows, the target member


12


has a bore hole


20


that travels wholly through the target member


12


for receiving the flexible retaining rod


14


therethrough. The target member


12


also has a countersunk bore hole portion


22


that extends only partially through the target member


12


for receiving the ball stop


18


so that the ball stop


18


does not project therefrom. Preferably, the countersunk bore hole portion


22


will be approximately as deep as the ball stop


18


is thick. With this, the ball stop


18


will not inflict damage to a striking implement, such as a ball bat, during use of the batting practice device


10


.




Disposed at the proximal end of the flexible retaining rod is a clamping structure, which is indicated generally at


16


in FIG.


1


and is shown more particularly in FIG.


3


. As

FIGS. 1 and 3

show, the clamping structure


16


allows the batting practice device


10


to be releasably secured to a fence, such as a chain link fence


100


, by a clamping of the wire strands of the fence


100


between a first clamping block


26


and a second clamping block


28


of the clamping structure


16


. With this, the batting practice device


10


can be removably and replacably coupled to a fence


100


or the like and can be readily transported to a practice field or a game field. Looking to

FIG. 3

, one sees that the clamping structure


16


is founded on a hollow or tubular retaining sleeve


24


, which is shown more particularly in FIG.


4


. The retaining sleeve


24


has a proximal end that comprises a widened disk that forms a clamp stop


30


against which the first clamping block


26


butts. Disposed in a facing relationship to the first clamping block


26


is the second clamping block


28


. As

FIG. 5

shows, the first and second clamping blocks


26


and


28


have apertures


58


and


60


therethrough through which the retaining sleeve


24


is received. With this, the first and second clamping blocks


26


and


28


are slidably and rotatably retained on the retaining sleeve


24


.




However, the first and second clamping blocks


26


and


28


can be fixed relative to one another against relative rotation by first and second engaging pins


40


and


42


that project from the inner face of the first clamping block


26


in combination with first and second pin engaging bore holes


44


and


46


in the second clamping block


28


. The first and second clamping blocks


26


and


28


certainly could be formed from a variety of materials as could the retaining sleeve


24


. However, due to its relatively light weight and high strength, a properly chosen aluminum alloy appears preferable.




To the distal side of the second clamping block


28


relative to the clamp stop


30


is a clamping nut


32


. The clamping nut


32


is threadedly engaged with the retaining sleeve


24


for rotation relative to threads


38


that are disposed on the retaining sleeve


24


. The clamping nut


32


is knurled in this preferred embodiment for better gripping by a user without a need for tools of any kind. Although the clamping nut


32


could be crafted from many different materials, the preferred clamping nut


32


is not formed from an aluminum alloy or any other metal material because clamping nuts


32


so formed have been seen to lock relative to the second clamping block


28


thereby making relative rotation between these elements difficult. Advantageously, the present inventor has remedied this difficulty by forming the preferred clamping nut


32


from a plastic, such as an acetal resin material. For example, a preferred acetal resin is that sold under the trademark black DELRIN by the company Du Pont de Nemours, E. I. & Co. Under this arrangement, the first and second clamping blocks


26


and


28


can be pressed together or allowed to separate by relative rotation between the clamping nut


32


and the retaining sleeve


24


.




As

FIG. 3

shows most clearly, the flexible retaining rod


14


passes entirely through the retaining sleeve


24


such that a most distal end of the flexible retaining rod


14


projects through and beyond the clamp stop


30


with which the rod clamping member


34


is engaged. A threaded fastener


36


passes through the rod clamping member


34


and into the clamp stop


30


for selectively drawing the rod clamping member


34


toward the clamp stop


30


thereby to compress about the flexible retaining rod


14


. With this, when the rod clamping member


34


so compresses about the flexible retaining rod


14


, the flexible retaining rod


14


will be fixed in place relative to the clamping member


34


and the retaining sleeve


24


in general. With this, a user can selectively fix the flexible retaining rod


14


in place during use of the batting practice device


10


, and a user can loosen the rod clamping member


34


to allow the flexible retaining rod


14


to be slid relative to the retaining sleeve


24


.




However, the invention provides a further means for preventing the flexible retaining rod


14


from inadvertently being pulled from within the retaining sleeve


24


in the form of a stop sleeve


35


, which is disposed surrounding the most proximal end of the flexible retaining rod


14


. As

FIG. 3

shows, the stop sleeve


35


comprises a cylindrical sleeve, preferably formed from metal, that is fixed to the flexible retaining rod


14


as by welding or similar methods. For completeness, one will note that the plastic sheathing ceases over the length of the flexible retaining rod


14


in the area of the stop sleeve


35


, and the stop sleeve


35


has a diameter approximately equal to the diameter of the flexible retaining rod


14


over the portion where the flexible retaining rod


14


is coated with plastic sheathing.




As a result, the effective length of the flexible retaining rod


14


as it extends beyond the distal end of the retaining sleeve


24


can be readily adjusted if necessary. Furthermore, the flexible retaining rod


14


can be entirely removed from the retaining sleeve


24


. This would be useful, of course, if replacement of the flexible retaining rod


14


is required due to damage or the like.




Looking again to

FIG. 5

, one sees that the first clamping block


26


has a first clamping furrow


48


and a second clamping furrow


50


communicating across its inside face. The first and second clamping furrows


48


and


50


are disposed in a generally parallel relationship. In this exemplary embodiment, each of the first and second clamping furrows


48


and


50


has a centerline that is disposed approximately 1 and ⅛ inches from the center of the aperture


58


whereby the centerlines of the first and second furrows


48


and


50


are separated by a distance of approximately 2 and ¼ inches. Advantageously, this distance matches the distance between adjacent wire strands on a typical chain link fence, such as that indicated at


100


in FIG.


1


. Matching first and second clamping furrows


52


and


54


are disposed on the second clamping block


28


.




Under this arrangement, installation and use of the batting practice device


10


is extraordinarily simple. For example, a typical practice session with the batting practice device


10


might begin with a user's rotating the clamping nut


32


counter-clockwise so that it travels along the retaining sleeve


24


toward the distal end thereof. With this, the first and second clamping blocks


26


and


28


can be separated, and the blocks


26


and


28


can be disposed to sandwich adjacent strands


102


and


104


of a fence


100


as is shown in

FIG. 1

with the first clamping furrows


48


and


52


aligned with the first strand


102


and the second clamping furrows


50


and


54


aligned with the second strand


104


. The clamping nut


32


could then be rotated in a clockwise direction thereby causing it to travel along the retaining sleeve


24


toward the proximal end thereof. With this, the first and second clamping blocks


26


and


28


will be compressed together to fix the first and second strands


102


and


104


in place within the respective channels defined by the first clamping furrows


48


and


52


and the second clamping furrows


50


and


54


. If necessary, the effective length of the flexible retaining rod


14


could be adjusted by loosening the rod clamping member


34


and sliding the flexible retaining rod


14


any desired amount.




With the batting practice device


10


so affixed to a fence


100


, a batter can immediately employ the batting practice device


10


to practice his or her batting technique or to warm up prior to the start of a game or a given at bat. For example, a batter could strike the target member


12


repeatedly during practice, possibly under the instruction of a coach or the like, to improve his or her batting ability. Furthermore, a batter could take a number of swings at the target member


12


immediately prior to stepping to home plate to refresh his or her muscle memory and, possibly, to quell his or her nerves. With each strike of the target member


12


by a striking implement, the flexible retaining rod


14


and thus the target member


12


will deflect a given amount only to return to its approximate starting position due to the resiliency of the flexible retaining rod


14


. As a side note, the astute observer may realize that attaching the batting practice device


10


to the links of a chain link fence


100


has the further advantage of having the fence


100


itself contribute to the resiliency of the batting practice device


10


in general as the links of the fence


100


will tend to give resiliently along with the flexible retaining rod


14


.




Advantageously, as one might infer from the foregoing, the batting practice device


10


can be installed in an exceedingly rapid manner without a need for any tools whatsoever. With this, installation of the device


10


will not be likely to interfere with the play of a given game, to discourage its own use, or to detract from the time available for using the device


10


. Furthermore, the device


10


is exceedingly simple in construction, much simpler than prior art practice devices, and has no moving parts during use. As a result, it can be manufactured in an efficient manner and demonstrates little susceptibility to breakage or malfunction. Most importantly, of course, the device


10


provides an effective means for a player to practice batting and to warm up prior to a game or a given at bat.




From the foregoing, it will be clear that the present invention has been shown and described with reference to certain preferred embodiments that merely exemplify the broader invention revealed herein. Certainly those skilled in the art can conceive of alternative embodiments. For instance, those with the major features of the invention in mind could craft embodiments that incorporate those major features while not incorporating all of the features included in the preferred embodiments. With the foregoing in mind, the following claims are intended to define the scope of protection to be afforded to the present inventor, and the claims shall be deemed to include equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.




One should further note that a plurality of the following claims express certain elements as a means for performing a specific function, at times without the recital of structure or material. As the law demands, these claims shall be construed to cover not only the corresponding structure and material expressly described in the specification but also equivalents thereof.
