DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a hitting tee training device used for baseball or softball, and more particularly, to a hitting tee training exercise for a beginner, and particularly to a portable exercise device useful for training to keep an eye on the ball. The present invention relates to a mobile electric hitting tee. The present invention can develop hand-eye coordination, especially when used for training in hitting a ball with a bat by slowly moving the ball toward a child. The present invention is, of course, also useful for any normal hitting practice.

2. Description of the Related Art There are many prior arts relating to hitting tees, but none of them move and are motorized in a designed manner, as shown in the present invention. Prior art is
Rather, it merely discloses a batting tee that can change the position of a ball hit with a bat in various ways. Except for prior art which seems to be somewhat relevant, the gist of the present invention is that any ball entering the strike zone immediately before being hit by the batting tee is disclosed in any prior art. It has not been.

[0003] A somewhat related prior art is noted in US Patent No. 4,575,080, issued March 11, 1986 to Michael E. Miles. This patent teaches a batting tee device having a blower for generating an air flow for suspending a baseball. The tee causes the baseball to swing vertically and / or move circumferentially. It also has an inclined outlet under its head to rotate the tee to keep the ball floating in the airflow. Thus, the device provides a simulation of ascending, descending, or curving as the baseball approaches the batter. However, this patent does not teach tee support movement, in which the ball contacts the tee as it moves toward the batter and enters the strike zone while remaining supported. Further, the present invention does not require a blower assembly with associated noise scattering and power demand features.

[0004] Batting tees that support a ball in a stationary state are well known. A publication entitled "How to make batting tees" teaches securing a radiator hose length in the cross section of a water tube and inserting the water tube into a plywood pedestal in the form of a home plate. The device may be stabilized by a sand weight. In addition, multiple holes are drilled in the home plate to insert tube segments, and various holes on the home plate are simulated to simulate the location of multiple balls in the strike zone. You may. A baseball is mounted on a radiator hose segment. Also, basic batting tees having vertical columns, an upper flex ball support, and a weighted pedestal configured as a home plate are well known. A toy batting tee, called a "tee ball", consisting of a metal tee and a plastic ball and bat, has been on the market in the past.

[0005] US Patent No. 5,388,823, issued to Ronald G. Prieto on February 14, 1995, is representative of many prior art teaching batting tees and includes a stationary state for hitting practice. Provide adjustable positioning of a baseball. A similar variable positioning batting tee supporting a baseball in a stationary position for hitting practice is found in U.S. Pat. No. 3,489,411 issued to Dominic J. Moreri et al. On Jan. 13, 1970. The batting tee taught from these two patents is:
It has an X-, Y-, and Z-axis adjustment device for the base of the baseball ball for hitting, but does not teach that the baseball ball placed on the tee is actually moved to the batter immediately before being hit. .

[0006] In addition, various variations on the subject of an adjustable batting tee in which a baseball ball is stationary have been proposed in 19th edition.

No. 4,993,708 issued to William Prosser et al.

The above prior art does not teach the present invention. Briefly, the present invention is a simple mobile electric batting tee that approaches a batter at a predetermined, pre-designed speed, where a batter swings a tee-supported ball with a bat. When the tee enters the strike zone, the ball remains on the tee.

It is believed that the above inventions and patents, alone or in combination, do not describe the claimed invention.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a method in which children, athletes and the like use a ball, such as a bat, racket, or bare hand, which is said to be one of the most difficult trainings in any sport. This is a mobile electric hitting tee for training to hit the ball accurately. When learning the technique of hitting a round ball with a round bat, it is important to keep an eye on the ball as it hits a virtual strike zone on the home plate adjacent to the batter.

Conventional batting tee devices are generally stationary and do not assist beginners in baseball training to keep an eye on moving balls. In the prior art described above, the ball supported by the airflow is curved,
It is useful for providing ball movement comparable to sinkers and other pitching, but it is possible to use a strike zone where the batter can train a little slower if necessary when training to keep an eye on the ball. No movement of the ball supported by the guided tee is provided.

Next, common functional features of the present invention will be described with reference to a plurality of drawings attached with reference numerals. First, FIG. 7 will be described, and then two different embodiments of the mobile electric hitting tee mainly shown in FIGS. 1 and 5 will be described. Referring to FIG. 7, a batter B practicing a batting utilizing the present invention is shown. In this example, the batter is right-handed, but may be left-handed. There is no need to change the invention.

No instrument for removing the battery 148 from 0 is required and can be removed by hand. Thus, the device can be taken to a playground without power equipment. If a plurality of batteries are prepared, the present invention can be used continuously. Furthermore, there is no need for dangerous electrical cords that can well interfere with play.

The hitting tees of the above two embodiments will be described in detail. Another embodiment of the hitting tee 14 includes an upper segment 50 that expands outward at an upper end 52 to receive a ball for a baseball or softball ball, and, as is often the case, with a bat. After it has been hit, it is formed of a suitable storage material to return to its original shape. Segment 50 includes a base segment 5 joined to drive rod 12 with an elbow 56.
4 seated. In another embodiment, rod 12 and L
The joints 56 are joined only by friction fitting. Thus, when the bat hits the tee 14 unintentionally, the entire tee falls off the rod 12 and the working parts of the present invention are not damaged. In yet another embodiment, segment 50 may frictionally engage base 54 and / or segment 54 may frictionally engage elbow 56. Various combinations of friction engagements are possible.
The components of the above-mentioned hitting tee may be changed in size or parts may be deleted. For example, segment 5
0 may be longer or shorter than shown, or may extend to an elbow 56 to eliminate the base segment 54.

As shown in the preferred embodiment, the exploded view of FIG. 4 is best seen, but the hitting tee 114 has an upper segment 151 that expands outward at the upper end 153 to receive the ball. The enlarged portion may be formed of an elastic material such as rubber or plastic. The remaining portion of the upper segment 151 may be composed of a tubular rigid material such as aluminum or other impact resistant material. In other words, a material is selected that eliminates damage from being hit off the target with a bat or other device. The upper segment 151 is slidably provided on the upper end 157 of the middle segment 154 of the tubular member having a dimension and shape to receive the upper segment 151. The upper end 157 has a threaded locking collar 156, well known in the art of tubular length adjustment means,
This seats at a predetermined height relative to the middle segment 154 to clamp the upper segment. With this configuration, the height of the tee can be adjusted according to the height of the user. The middle segment 154 is opposite the base segment 16
It has opposing threaded ends 158 that are threaded to zero.
Segment 160 is also tubular and is dimensioned to receive threaded end 158 of intermediate segment 154 at its upper end 161. Additional tees (not shown) that are also threaded and uniform in size to match the dimensions of the mating end of the associated segment,
The height of 4 may be extended if necessary.

To reduce the impact of an off-target bat hit on upper segment 151, base segment 160
Has a coil spring 156 disposed between the upper end 161 and the base end 163. The base end 163 is attached to the mounting base 113 (FIG. 1).
See) for threading into mating threaded holes. When the tee bends forward with the bat striking force, the base segment 160 swings to provide a swing function to absorb force energy. The coil spring 156 preferably has a tension that keeps the tee in a stationary state upright and immovable and prevents the tee from moving in the vertical direction while the thread 116 is in a reciprocating state.

Here, the operation of the motors 32, 142 for operating the movable tees 14, 114 will be described. Each motor 32, 142 may include features for changing the speed of movement of the tee 14 with respect to the batter. This means that it can be used at different skill levels and ages (for example, slower for children and faster for middle and high school students)
Or you can choose low speed. Alternatively, the speed may be changed during the movement of a single ball. That is, tees 14, 114
Starts moving at low speed and is accelerated as the tee enters the strike zone. In addition, the operation of the motors 32 and 142 may be performed via a control box that is rigidly wired to the motor 32 or as illustrated in the handset 144.
It can be performed by remote control without wiring. These changes themselves are well known to those of ordinary skill in the art and will not be described in detail here.

A mobile tee ball player federation may be established. To that end, a portable handle 170 is attached to the boxes 10, 110 to remove the home plate and move the entire device when a match is played.
(Only shown in FIG. 3 for the preferred embodiment) may be provided. In addition, a ditch may be dug as the rod 12 moves, or, perhaps more likely, the rod 12 may be reconfigured to move over the ground to provide a durable device with a box section. Can be concealed.

Thus, the present invention is believed to provide a whole new meaning and definition for the industry designation "tee ball." The ability to express a fairly realistic confrontation of the batter and the batter obtained by actually moving the ball to the batter's strike zone can enhance the training of new baseball players, while for skilled players, Provides a new practice range. The invention may be used for training athletes or as part of a tee ball game. Further, since the present invention has a simple structure, it does not malfunction and can withstand abuse.

The present specification is not limited to the above embodiments, but encompasses all embodiments of the appended claims.
