Abstract

This present invention is a baseball training device for practicing hitting, comprising a swing member supporting either a static and dynamic balanced arm member having a ball at one end or a ball holder member freely supporting a ball. The swing member is supported by a base member and is restored to its equilibrium position in hitting practice mode by gravity. The rotation of the static and dynamic balanced arm member and oscillation of the swing member aid in the dissipation of force imparted to the device in hitting practice mode, making the device stable and stationary, portable and lightweight.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
There are many types of baseball training devices with which practicing hitting involves hitting a ball with extreme force. The present invention is one of them.
2. Description of Prior Art
Any discussion of the prior art throughout the specification should in no way be considered an admission that such prior art is widely known or forms part of common general knowledge in the field. With baseball, beginners seek to learn to swing; non-beginners strive to perfect their swings. For beginners, it is very desired if they can maximise the number of swings in a given period of time. For serious players, they would like to maintain their swings. When practicing hitting with a training device, some players prefer to have the ball attached to the device; others prefer not to have the ball attached to the device so as to see the trajectory the ball will take after it is hit. Many baseball training devices for practicing hitting have been developed over the years. Baseball prior art relevant to the present invention are U.S. Pat. No. 3,994,494 to Kelly; U.S. Pat. No. 4,966,367 to Oyarzabal; U.S. Pat. No. 6,099,419 to Incaudo et al; U.S. Pat. No. 6,296,582 to Minniear; U.S. Pat. No. 6,306,050 to Holder; U.S. Pat. No. 1,962,087 to Cone; U.S. Pat. No. 5,618,039 to Tsai et al. The commonality of the present invention with a sub-set of prior art is they seek to allow the player to practice in a small space. The commonality of the present invention with another sub-set of prior art is they seek to allow the player to see the trajectory of the ball after it is hit. The present invention diverges from all such prior art most importantly in the way it deals with the force imparted to the device when the ball is hit.

BRIEF SUMMARY OF THE INVENTION

One of the objectives of the present invention is to provide a baseball training device for practicing hitting without the need for a net.
Another objective of the present invention is to provide a baseball training device that is lightweight and portable and can withstand the extreme force applied when practicing hitting.
Another objective of the present invention is to provide a baseball training device that can be used equally indoors and outdoors, by both right handed and left handed players, for practicing hitting.
Another objective of the present invention is for it to be used as a Tee.
Another objective of the present invention is for it to be used to practice a level swing.
The design of the present invention achieves these objectives by incorporating a number of features from prior art, namely having a ball affixed at the end of an arm, having a ball holder member, and lastly having a horizontal guide to practice a level swing. However, it departs from prior art in the manner it achieves these objectives. With the present device, in one configuration the ball is affixed to the end of a static and dynamic balanced arm member. When the ball is hit, force is imparted to the device forcing it to move forward, upward or downward, and sideways. To minimise or prevent such movement, prior art devices have been made heavy and/or staked to the ground. To minimise forward and upward or downward movement of the base member of the present device, the base member supports a swing member which supports the static and dynamic balanced arm member with a ball at one end. When the ball is hit, the swing member oscillates, allowing the base member to be substantially stationary. Secondly, the static and dynamic balanced arm member can rotate completely, clockwise and counter-clockwise. When the ball is hit, the static and dynamic balanced arm member rotates which minimises movement, sideways and forward, of the present invention. In a second configuration, the base member supports a swing member which supports a ball holder member. When the ball is hit, it flies off the ball holder member leaving the device stationary. However, if the ball holder member itself is hit the swing member oscillates, preventing the collapse of the device as in traditional Tees.
Furthermore, the aim of this application is to illustrate the preferred embodiments and to broadly state the methodologies that may be used with this baseball training device to practice hitting.

This invention has been disclosed and described in its preferred embodiment with a certain degree of peculiarity; it is understood that the present disclosure of the preferred embodiment is only by way of example and that numerous changes in the details and arrangements of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.

Method of Use

There are three ways of practicing hitting with the present device—(a) with the static and dynamic balanced arm member, (b) with the tee, and (c) with a combination of the tee and the bridge member. With the static and dynamic balanced arm member, there are two ways of practicing hitting—stationary and simulated. When practicing stationary hitting, the ball is motionless and can be positioned so that the pitch is early, late or right over the plate. With simulated pitching, the arm is rotated counter-clockwise into the hitter if right-handed or clockwise if left-handed. Hitting with the tee is self-explanatory. When hitting with a combination of the tee and the bridge member, the tee is lowered so that the ball is just higher than the bridge member. This forces the player to swing level with the bridge member when hitting the ball. If the player swings up he/she would hit the front legs of the device.
