## Background
This United States patent application is a continuation of U.S. patent application Ser. No. 12/807,211, filed Aug. 30, 2010, hereby incorporated by reference herein.


I. BACKGROUND
A sports activity swing trainer having a concave curved surface area on which a person stands to practice a swing for a sports activity.
A person typically practices a sports activity swing on a generally flat support surface. The person from practice session to practice session and from swing to swing learns the sports activity swing in relation to a limited range of difference in the person's center of gravity. However, this approach does not challenge the person to alter the sports activity swing or develop a sports activity swing responsive to a wide range of difference in the person's center of gravity.
II. SUMMARY OF THE INVENTION
Accordingly, a broad object of the invention can be to provide a sports activity swing trainer which provides a concave curved surface adapted to allow a person to stand on while practicing a sports activity swing.
Another broad object of the invention can be to provide a method of sports activity swing training in which a person alters location of the feet on a concaved curved surface to corresponding alter the person's center of gravity which challenges the person to develop a sports activity swing responsive to the change in the person's center of gravity.
Naturally, further objects of the invention are disclosed throughout other areas of the specification, drawings, photographs, and claims.

IV. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
First referring primarily to FIG. 1, a particular embodiment of a method of sports activity swing training (1) is shown in which a person (2) stands on a concave curved surface area (3) supported by a base (5) in fixed relation to a support surface (4). The person (2) standing on the concave curved surface area (3) can swing an elongate member (6) through one or more sports activity swings (7). The elongate member (6) can be one of a variety of swingable elongate members (6) such as a golf club, any of a numerous and wide varieties of sports activity swing trainers, baseball bat, baton, tennis racquet, racquet ball racquet, or the like. The standing location (8) on the concave curved surface (3) can be altered to correspondingly alter the center of gravity (9) of the person (2) during said step of swinging the elongate member (6) through one or more sports activity swings (7). By standing on the concave curved surface area (3) at a standing location (8) which raises the toes (10) of the foot (11) in relation to a heel (12) of the foot (11) moves the person's (2) center of gravity (9) backward. Conversely, by standing on the concave curved surface area (3) at a location which raises the heel (12) in relation to the toes (10) shifts the person's (2) center of gravity (9) forward. Each foot (11) of a person (2) can be located in essentially limitless combinations on the concave curved surface area (3) which correspondingly shifts the person's (2) center of gravity (9) to different locations. Altering the person's (2) center of gravity (9) further alters the swing plane of the sports activity swing (7). The swing plane affects the direction and velocity of a sports activity ball hit with a sports activity club. By using the method above described the person (2) can experience a wide and numerous variation in center of gravity (9) affecting the swing plane of the sports activity swing (7). Accordingly, the person will quickly learn to adjust the sports activity swing (7) to compensate for the change in center of gravity (9).
Additionally, embodiments of the method of sports activity swing training (1), above described, encourages rotary motion of the upper body in relation to the lower body. The upper body and lower body are capable of twisting in opposite directions. This upper body can rotate all the way through to the other side ideally in balance and with a minimal lateral motion to generate the greatest speed, power and repetition accuracy in the swing (7). When feet (11) are positioned on the concave curved surface (3) as above-described rotary motion is encouraged and lateral motion is discouraged. This occurs because the concave curved surface (3) ‘pinches’ the body to stay centered and balanced as person (2) rotates. The more balanced the person (2), the faster the swing (7).
Now referring primarily to FIGS. 2-6, a particular embodiment of a sports activity swing trainer (13) is shown which includes a top (14) providing a concave curved surface area (3) adapted to support a person (2) standing on the concave curved surface area (3). A base (5) coupled to the top (14) can be configured to support the concave curved surface area (3) in substantially rigidly fixed relation to the support surface (4) which allows the person (2) to stand within the concave curved surface area (3). The term “substantially rigidly fixed relation to the support surface” for the purposes of this invention means that embodiments of the concave curved surface are substantially inflexible or do not move in relation to the support surface in response to a person standing on the concave curved surface”. This differentiates the concave curved surface of the invention from other conventional training devices such as inflatable balance trainers or compressible balance trainers which have surfaces that are substantially altered in configuration and move in relation to a support surface in response to a person standing on the trainer.
As to certain embodiments of the sports activity swing trainer (13), the concave curved surface area (3) can provide substantially the entirety of the surface area of the top (14) (as shown in the Figures), while as to other embodiments of the sports activity swing trainer (13), the concave curved surface area (3) can comprise a portion of the top (14). The concave curved surface area (3) can have dimensional relations which are sufficient to allow a person (2) to stand within the concave curved surface area (3); however, certain embodiments of the sports activity swing trainer (13) can provide a concave curved surface area (3) of substantially greater area and even an area sufficient to allow more than one person (2) to stand within the concave curved surface area (3). As to those embodiments configured to allow one person to stand on the concave surface area (3) the length (17) can be in the range of about 36 inches to about 60 inches and the width (16) can be in the range of about 24 inches to 36 inches; but the invention is not so limited.
Again referring primarily to FIGS. 2-6, certain embodiments of the sports activity swinger trainer (13) the concave curved surface area can be curved in single direction along the width (16) or curved in a single direction along the length (17) or curved in both directions along the length (17) and the width (16). The amount of curvature in a single direction can vary between embodiments of the sports activity swing trainer (13) but embodiments of the concave curved surface area (3) can have a radius in the range of about 36 inches and about 90 inches; however, the invention is not so limited, and the amount of curvature can be of lesser or greater radius useful in swing training, as above described. The amount of curvature in the width (16) can be of lesser or greater radius than the length (17) or can be substantially the same. Certain embodiments of the sports activity swing trainer (13) can provide a concave curved surface (3) which has a configuration of a partial sphere (18). As a non-limiting example, the radius of the partial sphere (18) can be in the range of about 36 inches and about 90 inches; however, the invention is not so limited.
Now referring primarily to FIGS. 2-6, the base (5) coupled to the top (14) can be of any configuration which supports the concave curved surface area (3) with sufficient stability to allow a person (2) to perform the method of sports activity swing training (1) above-described. Referring specifically to FIGS. 4-6, certain embodiments of the base (5) of the sports activity swing trainer (13) can be a substantially solid constructional form, or can be a solid constructional form reduced in mass by including a plurality of recess elements (20) which communicate with the bottom surface (21) of the base (5) as shown for example in FIGS. 4 through 6. Certain embodiments of the base (5) of the sports activity swing trainer (13) can have a substantially hollow constructional form defined by side walls (19) which bound a hollow space beneath the concave curved surface area (3). Whether the base (5) takes a solid, semi-solid, or hollow constructional form the side walls (19) of the sports activity swing trainer (13) have a height sufficient to establish the entirety of the concave curved surface area (3) above the support surface (4). Accordingly, the height of the side walls (19) can vary depending upon the amount of curvature in the concave curved surface area (3). Understandably, the greater the amount of curvature the greater the height of the side walls (19) to avoid contact of the concave curved surface area (3) with the support surface (4).
Now referring primarily to FIGS. 1-5, certain embodiments of the sports activity swing trainer (13) can further include an aperture element (23) disposed generally in the center of the concave curved surface area (3). The aperture element (23) has dimensional relations which vary depending upon the amount of curvature of the concave curved surface area (3) and the height of the base (5). Understandably, as above-described, if the base (5) has sufficient height no aperture element (23) may be necessary. As the height of the concave surface area (3) approaches the support surface (4) by reduction in height of the base (5), or otherwise, the lowest point within the concave surface area (3) can contact the support surface (4). To produce embodiments of the sports activity swing trainer (13) which establish portions of the concave curved surface area (3) closer to the support surface (4), it may be necessary to remove a portion of the concave curved surface area (3) producing the aperture element (23). As the height of the base (5) is further reduced the open area (24) of the aperture element (23) increases.
Now referring to FIGS. 2 and 3, certain embodiments of the sports activity swing trainer (13) can further include a pass through element (25) which communicates between the bottom surface (21) and the top (14) (which in certain embodiments may be within the concave curved surface area (3)). The pass through element (25) can be located sufficiently proximate the edge of the sports activity swing trainer (13) and can have sufficient pass through area (26) to be grippably engaged by the hand (27) of a person (2).
Again referring to primarily to FIGS. 2 and 3, and FIGS. 4 and 5, certain embodiments of the sports activity swing trainer (13) can further include a friction element (28) coupled to all or a portion of the concave curved surface area (3). The friction element (28) can be provided by a wide and numerous variety of configurations, patterns, or materials made integral or applied to the concave curved surface area (3). As one non-limiting example, the friction element (28) can be a pattern of raised elements (29) applied, molded or otherwise established in the concave curved surface area. Alternately, the raised elements (29) can be established by a pattern of recessed elements (30) molded, fabricated, or cut or otherwise established in the concave curved surface area. Other embodiments of the friction element (29) can include a layer of material (31) (as shown in FIG. 2) which covers all or a portion of the concave curved surface area (3). The layer of material (31) can have slip resistant characteristics integral to the material such as rubber, neoprene, or the like, or can have a roughened or patterned surface such as treads, dimples, or the like, or can have adhesive characteristics; or abrasive characteristics conferred by particles applied to the surface.
As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a sports activity swing trainer and methods of practicing a sports activity swing.
As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.
It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of “sports activity swing trainer” should be understood to encompass disclosure of the act of “sports activity swing training”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “sports activity swing training”, such a disclosure should be understood to encompass disclosure of “sports activity swing trainer” and even a “means for sports activity swing training.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.
In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.
All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result.
Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.
