Tennis Trainer Apparatus

Abstract

A tennis trainer apparatus has a base, a center tube, and an upper structure. The base of the tennis trainer apparatus has a plurality of evenly distributed legs which may have wheels attached for ease of positioning the apparatus in various positions on a tennis court. The center tube is easily adjustable by placing a pin in holes at varying heights. The upper structure has a left arm and a right arm, and each arm has a holding rod attached. A ball with a ball loop is removably attached to the holding rods so that when the ball is struck it can easily travel like a regular tennis ball. The ball loop is attached to the ball through use of a small rod which is inserted into the tennis ball. Ball extenders with at least one and preferably two holding rods attached are used to raise and lower the height of the ball and ball loop, to create any shot in tennis, including a serve. A tennis trainer apparatus can be easily adapted to additional sports.

Players of sports require hand-and-eye coordination which skills improve with practice. Various training apparatuses have been developed to help players practice, but these apparatuses lack in efficiency, flexibility, affordability, and portability.

Tennis can be practiced, for example, by hitting a ball against a solid wall, but there is a lack of control in this practice. Throwing machines exist which throw a plurality of balls for the player to hit, but these have barriers in the speed, path, and rotation of the ball which may be difficult to surmount initially. Beginning players find these throwing machines to be difficult to master. Additionally, these machines are expensive to purchase.

Static tees have also been used to improve ball hitting skills. Such tees consist of a substantially cylindrical post with a lower end supported by means of a base stand or driven into the ground. An upper end of the substantially cylindrical post is substantially cup shaped and supports a ball. These are more useful for baseball and softball, but the tee would get in the way of a tennis racquets.

Tethered ball practice devices are well known in the prior art. These tethered ball practice devices consist of a ball fixedly or releasably attached to a frame or support. The frame or support may be a simple pole or a pole with an extension. Devices known in the prior art provide the opportunity to hit only one ball before resetting the device. These devices do not promote natural movement of the game of tennis because such devices allow only one hit at a time. Furthermore, tethered ball practice devices have a ball which swings in concentric circles, and the ball does not behave as a regular tennis ball.

SUMMARY OF THE INVENTION

This summary is provided to introduce a selection of concepts in a simplified form, that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter. Nor is this summary intended to be used to limit the claimed subject matter's scope.

A tennis trainer apparatus is used to make learning the game of tennis easier, faster, and with much improved results over current teaching methods. The tennis trainer is designed to be placed on a tennis court as a learning tool for an instructor to use while teaching a student the art of playing tennis properly. The tennis trainer holds a tennis ball suspended in midair at various hitting positions that a student needs to learn. With the ball suspended, the instructor is able to guide the student in stance, racket position, footwork, holding the racket and hitting the ball. When the ball is hit, it leaves the tennis trainer and travels like a regular tennis ball. A student can practice with or without supervision. A student can advance rapidly in tennis by using drills in a simulated tennis game situation.

A tennis trainer apparatus is used to teach both forehand and backhand as well as overhead and slicing in a natural, flowing movement to a student. The tennis trainer apparatus consists of a base which may have wheels supporting an inner vertical member which supports a right and a left holding rod. Said holding rods have horizontal training rods which hold ball loops with tennis balls attached. Alternatively, the horizontal training rods may hold extension arms which can be used to adapt the height of a tennis ball. A storage rack may alternatively be incorporated into the design of the tennis trainer apparatus or be a free-standing device. The tennis balls used with the tennis training apparatus are modified by inserting a small rod with a loop fixedly attached into a premade hole in the ball. The small rod fixedly attaches the ball loop to the ball.

Both the foregoing summary and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing summary and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.

Advantages

Accordingly several advantages of one or more aspects are as follows: a tennis trainer apparatus is used to teach both forehand and backhand as well as overhead and slicing in a natural, flowing movement to a student. A tennis trainer apparatus is adaptable, with extension arms which can be used to adapt the height of a tennis ball. The tennis trainer apparatus is adaptable in height. A training tennis ball is made by inserting a slender rod into a pre-punched or predrilled hole in a tennis ball. The training tennis ball slides off the tennis trainer with minimal friction and approximates a regular tennis ball in play. The tennis trainer apparatus can also be used for conditioning. A person of any age can use the tennis trainer to increase strength, movement, and cardiac health.
