FIELD OF INVENTIONThis invention generally relates to a batter training apparatus utilizing a vertically and horizontally adjustable tee to allow a user to learn and practice proper technique for hitting a ball with a bat.
BACKGROUND Prior ArtA batting tee is used by baseball players and coaches in teaching, learning and practicing the skills involved in hitting a baseball. A ball placed upon a tee that can be moved horizontally to spots on and around the home plate area coupled with vertical tee adjustment, allows the users to simulate the various pitches a batter must learn to hit. The player, through repetition and instruction, can develop consistent proper technique required to hit the various pitches thrown in a game.
During instruction or practice it is desirable for the player or coach to be able to make quick, easy and spontaneous adjustments to the tee. It is desirable that the tee be capable of unlimited horizontal adjustability on and around the home plate area and also have ample vertical adjustability. It is also desirable that this adjustability be accomplished instantly and easily without the use of cumbersome adjustment devices such as pins, clips, brackets, tracks, pivots, holes, pegs, rails or legs. Furthermore, it is advantageous for the tee to have adequate stability to prevent nuisance tipping or other movement as this causes the user to spend an inordinate amount of time resetting the tee, thereby disrupting the efficiency and rhythm of practice. Finally, it is desirable that the tee be able to tip in the instance of a mishit to prevent damage to the tee and that the tee can be quickly reset to the desired spot.
An added benefit is a tee that is portable and useable in a variety of locations on a variety of substrates (such as sand, gravel, wood or artificial turf) regardless of the availability of an existing home plate and that this same tee require no extra weighting, shims, blocking or bracing.
A typical batting tee consists of base, which is often in the shape of a baseball home plate but sometimes square or round. Attached vertically to the base, (usually centered), is a set of telescoping tubes on top of which a ball can be placed. The top of the ascending tube may act as the ball holder or the ascending tube might be fitted with a ball holding device. Ball height adjustment is made utilizing the telescoping action of the vertical tubes. If the tee is permanently attached to the base, horizontal adjustment is made by moving the entire apparatus to a different area of the ground. Other tees use integrated tracks, brackets, sockets, pins, pivots or legs. Several tees of the former description are known in the prior art. U.S. Pat. No. 3,883,138 to Chorey and U.S. Pat. No. 6,358,163B1 to Tanner disclose such designs. Tees of this type suffer from a lack of stability especially on uneven substrates or when placed on the borders of an elevated home plate. These tees are also prone to nuisance tipping and movement. While some allowance for tipping can be beneficial to prevent tee damage on mishits, a tee that tips too easily must be reset even when the batter strikes the ball within an acceptable range of accuracy. This tipping movement creates an annoyance and detracts from the teaching, learning or practice objective. Users frequently are forced to stack auxiliary weights on the base of the tee to gain stability.
Another tee with a with a permanently attached base is disclosed in U.S. Pat. No. 5,386,987 to Rodino, Jr. This device uses a larger heavier base and rigidly connected telescoping rubber pipes for vertical adjustment. Because of the large intrusive base such a tee is very limited in horizontal adjustability. The rubber pipe ball holder is too bulky and creates excessive interference with the batters swing. This type of tee has no built in protection from mishits. Thus, it is susceptible to damage, tumbling and nuisance shifting.
An effort at adding some horizontal adjustability to the Rodino design is disclosed in U.S. Pat. No. 4,227,691 to Lefebvre, et, al. The options available for adjustment are limited to a few predetermined choices as dictated by locating holes installed through the base. Also, the adjustment requires the inconvenient process of unscrewing the telescopic pipe ball holder assembly from a threaded disc located under the base of the tee and reassembling it at another hole location. The bulky rubber pipe ball holder creates excessive interference with the batters swing and also has no built in protection from mishits making it vulnerable to damage, tumbling and nuisance shifting.
U.S. Pat. No. 5,556,091 to Lin discloses an attempt to improve horizontal adjustability by attaching the vertical telescoping pipe assembly to a pivoting swivel mount. The mount rotates on a centrally located bolt on the base and engages locating holes in the base surface via a spring loaded bolt. The location options are restricted by the range of the pivot and the limited number of locating holes. The tee's design makes no allowance for being struck by the bat on mishits and is susceptible to damage, nuisance shifting and tumbling.
Yet another attempt to improve the range of horizontal adjustment is disclosed in U.S. Pat. No. 7,354,360 B1 to Eckstein. This tee design utilizes a steel base consisting of two legs secured at 90 degree angles in regard to each other, forming an X. The X base is set on the ground centered over an existing home plate. The tee element has a magnet attached at the bottom end that allows it to be coupled to various locations on the steel X base. To reposition the tee the user must step on the X base to disengage the magnet for repositioning. Horizontal adjustment is limited to the area upon the X base. The design's chosen magnet is of a strength that prevents disengagement on mishits and thus the tee design is susceptible to damage and nuisance shifting. The X base design is prone to stability issues especially when the tee is positioned on the outer ends of the X legs.
Prior art discloses batting tees that use a track or channel system to facilitate horizontal adjustment, as is disclosed in U.S. Pat. No. 6,099,418 to Owen. The tee is secured to a channel installed in the base with the use of a track follower that slides in the track and is secured to the bottom of the tee with the use of a threaded shank. This creates a rigid connection that will be very susceptible to damage, as well as nuisance shifting and tumbling on mishits. Horizontal adjustability is limited to locations made available by the layout of the installed track.
U.S. Pat. No. 4,445,683 to Cardieri discloses a tee design that utilizes a tube and aperture arrangement for horizontal adjustment. The vertical adjustable tee member is inserted into vertically aligned apertures supported by a bi-level base with the bases divided by spacers. Horizontal adjustments are limited to the provided apertures. The design does not offer any protection from the force of mishits which will result nuisance movement and damage to the vertical tee member.
SUMMARYIt is an object of the present invention to provide a readily adjustable batting tee apparatus that has an expanded range of horizontal positioning and is unencumbered by limiting adjustment devices. In addition, horizontal positioning is achieved and maintained in a way that allows for tee stability while simultaneously limiting susceptibility to damage on mishits. The apparatus includes a batting tee platform component with a perimeter appreciably larger than a standard sized home plate and an independent vertically adjustable tee component. The tee platform's surface is magnetically attractive and furnished with a home plate applique. The tee is equipped with a magnetic base that allows it to be securely positioned without limitation upon the batting tee platform. The tee base's magnetic force is sufficient to hold the tee in place on reasonable bat contact but will release when subjected to mishits. Because the tee platform is substantial enough to maintain position if the tee is dislodged, it is a simple matter to reset the tee and resume activity. Desired horizontal adjustment is made by tipping the tee in any direction to break the magnetic bond and setting the tee on the desired spot. Vertical tee adjustment is achieved through simple manipulation of a set of telescoping tubes, with the adjustment held in place by friction contact made at several points within the tubes assembly. A ball holder suitably sized and made of a resilient material allows bat to ball contact to occur with minimal interference.
Presented in the drawings is a preferred embodiment of a batting tee platform and accompanying tee.
Attachment of sheet steel 21 to plywood base 20 is preferably accomplished using contact cement. The sheet steel could be attached with other adhesives or with mechanical fasteners such as screws. Alternative embodiments might replace the use of sheet steel 21 with the use of steel strips attached across platform base 20 or steel rods inlayed into platform base 20. However, maximum horizontal adjustment capability is achieved when the entire surface 18 area is magnetically attractive. Also a flat, smooth surface 18 provides a superior finish and an uncluttered appearance.
When attachment of sheet steel 21 to platform base 20 is complete all sides are sanded and edges eased to eliminate any sharp surfaces and prepare for finishing. Tee platform 8 is then painted with a durable exterior grade paint or comparable durable coating. Surface 18 painting includes a representation of home plate 19 in a contrasting color, preferably white. Surface 18 painting or home plate 19 painting might be replaced by the use of decals or other coating application techniques. Finishing not only protects batting tee platform 8 from environmental damage but also enhances aesthetic appeal. Color selection could match various field surface types.
Handle 22 attachment is undertaken upon completion of final finish coating. Preferred handle material is strong and flexible such as nylon web strap. This type of material is abrasion resistant, won't break if stepped on and will allow tee 10 and platform 8 to be carried together in one hand. Other materials such as rope or vinyl or plastic strap could be used. A shoulder strap might also be used for carrying purposes. Handle 22 is attached to tee platform 8 with mechanical fasteners such as screws 23 with finishing washers 24.
